Plasma sex hormone binding globulin (SHBG) and testosterone levels were measured in 29 patients with epilepsy (16 men and 13 women), most of them on chronic therapy with anticonvulsant drugs. Sex hormone binding globulin concentrations were increased in both sexes and testosterone levels in male patients. It is postulated that anticonvulsants may induce hepatic synthesis of SHBG.

In vitro thyroid testing in populations with low thyroxine binding globulin capacity

Total thyroxine (T{sub 4}) concentration in serum is a reliable indicator of thyroid function in most individuals, but it is affected by altered concentrations of thyroxine-binding globulin (TBG) in serum. Within certain limits, the variations in total TBG binding capacity (TBG{sub TOTAL}) caused by the fluctuations in the concentration of this binding globulin in serum can be modulated by calculating the free thyroxine index (FT{sub 4}I) as the product of T{sub 4} and the in vitro uptake of triiodothyronine by a secondary binder (T{sub 3}U). This calculation is empirically based on the facts that free TBG binding capacity (TBG{sub FREE}) is inversely related to T{sub 3}U and that T{sub 4} and T{sub 3}U show opposite behaviour when measured in sera with altered TBG: a low T{sub 4} in serum with reduced TBG{sub TOTAL} is compensated by a high value for T{sub 3}U, while an elevated T{sub 4} in serum with increased TBG{sub TOTAL} is compensated by a low value for T{sub 3}U. In both cases the product of T{sub 4} and T{sub 3} renders a normal FT{sub 4}I value, showing a certain association with the concentration of free T{sub 4} in serum (FT{sub 4}). In fact, this index has been shown to be superior than several FT{sub 4} assay systems in the assessment of thyroid status in clinical euthyroid subjects with relatively high or low T{sub 3}U 3 figs, 4 tabs

1985-01-01

Five-month-old lean and obese Zucker rats were fasted for up to 7 days (lean rats) or 28 days (obese rats), and serum total and free T4 and T3 concentrations, percent free T4 and T3 by equilibrium dialysis, and the binding of [ 125 I] T4 to serum proteins by gel electrophoresis were measured. In the lean rats, a 4- or 7-day fast resulted in significant decreases in serum total and free T4 and T3 concentrations. There was a decrease in the percent free T3 after 7 days of starvation. In contrast, a 4- or 7-day fast did not alter any of these variables in the obese rats. However, after 14 or more days of starvation, serum total T4 and T3 concentrations increased, and the percent free T4 and T3 decreased, resulting in no change in the serum free T4 or T3 concentrations in the obese rats. The percent of [ 125 I]T4 bound to serum thyronine-binding globulin increased and the percent bound to thyronine-binding prealbumin decreased with the duration of the fast in both the lean and obese rats. The increase in serum thyronine-binding globulin binding of T4 can explain the increase in serum total T4 and T3 concentrations, the decrease in percent free T4 and T3, and the normal free hormone concentration in the long term fasted obese rats. The findings in the lean rats appear to be due to a combination of the known central hypothyroidism that occurs during 4-7 days of fasting and the fasting-induced changes in T4 binding in serum. Changes in T4 and T3 binding in serum during fasting in the rat must be considered when the effects of fasting on serum concentrations of the thyroid hormones, thyroid hormone kinetics, and the peripheral action of the thyroid hormones are evaluated

2008-06-01

Albumin and globulin fractions of 1 Desi and 2 Kabuli varieties of chickpeas (Cicer arietinum) were extracted with water and salt solutions (K(2)SO(4) and NaCl). The extractable yields and particularly the albumin-globulin ratio varied greatly with the extraction medium and chickpea variety. Depending on the procedure employed, albumin could be extracted as a major fraction of chickpea proteins. Higher levels of essential amino acids and sulfur containing amino acids were found in albumins than in globulins of all chickpeas investigated. The common structural characteristics of both Kabuli and Desi chickpea albumins and globulins were clearly identified by densitometric profiles of their sodium dodecyl sulfate polyacrylamide gel patterns. Albumins contained subunits with higher molecular weights than those of globulins. The in vitro digestibility of the chickpea proteins by papain, pepsin, chymotrypsin, and trypsin indicated that globulins were more susceptible to proteolytic hydrolysis.

The molecular biology and biochemistry of rice endosperm α-globulin

International Nuclear Information System (INIS)

Shorrosh, B.S.

1989-01-01

The author's first objective was to isolate a cDNA clone that encodes the rice endosperm α-globulin. Purified antibodies against a rice storage protein, α-globulin, were used to screen a λgt11 cDNA expression library constructed from immature rice seed endosperm. The cDNA insert of clone 4A1 (identified by antibody screening) was used as a probe to identify long cDNA inserts in the library. The deduced amino acid sequence of clone A3-12 cDNA insert (identified by cDNA screening) contained the amino acid sequences of three cyanogen bromide peptides fragment of α-globulin. The calculated molecular weight and amino acid composition of the deduced amino acid sequence were similar to the α-globulin protein. Northern blot analysis indicated that mRNA of one size, approximately 1.0 kb, is expressed. Southern genomic blot analysis revealed one band with EcoRI or Hind III digestion. Cell-free translation and immunoprecipitation showed that the initial translation product is approximately 2,000 daltons larger than the mature protein. The amino acid sequence of α-globulin revealed limited regions of similarities with wheat storage proteins. The author concludes that the cDNA insert in clone A3-12 contained the entire coding region of α-globulin protein and that α-globulin is encoded by a single gene. My second objective was to inhibit the degradation of α-globulin in the salt extract of rice flour. The salt extract of rice flour contained an acid protease whose optimal pH was 3 for 3 H-casein hydrolysis. A polypeptide with molecular weight of 20,000 was immunologically reactive with α-globulin antibodies and is produced by limited proteolysis in the extract. Pepstatin inhibited the proteolysis of 3H-casein and slowed the proteolysis of α-globulin

In spite of considerable experience of practical use of serum globulin preparations, their effect on automicroflora wasn't studied. The favorable effect of therapeutic injection of homologous serum globulin preparations on automicroflora of small and large intestine of mices was established for the model of acute radiation sickness caused by /sup 60/Co irradiation with 700 R dose. The effect of injecting two types of globulin preparations was studied: ones prepared of blood of intact and hemostimulated mices (to increase the content of normal antitissue antibodies in the serum). Besides the general globulin fraction isolated by ammonium sulfate precipitation a study was made on the effect of purified IgG and IgM preparations. Threefold subcutaneous or intraperitoneal globulin in ection of 1 ..mu..g dose in a mice prevented after 2, 24, 48 h after irradiation the development of bacteriosis, typical for radiation injury - decreased accumulation of putrefactive bacteria and reduced the suppression of lactobacilli content. Globulin preparations and fractions of hemostimulated mice serum, enriched by normal antitissue antibodies are the most effective ones.

CONFORMATION CHANGES OF HUMAN SERUM γ–GLOBULIN IN THE PRESENCE OF ZINC IONS

Full Text Available Abstract. Conformational changes of human serum γ–globulin during interaction with the zinc ions were studied in a solution. It has been shown that the presence of zinc in over its physiological concentrations led to increase in optical density across the whole spectrum of γ–globulin ultraviolet absorption. On the contrary, hypochromia in the spectrum was registered after interaction of the protein with zinc used in subphisiological concentrations. Possible role of divalent metal cations in changes in conformation of the blood serum γ–globulins, and thereby in regulation of their effector functions was discussed. (Med.

Objective The association ns between prediabetes and androgens have been rarely reported, especially in Chinese men. We aimed to investigate whether androgens were associated with the prevalence of prediabetes diagnosed with new American Diabetes Association criteria in Chinese men and then to assess which androgen value was the most relevant factor. Methods A total of 2654 men (52.6±13.4 years old) were selected. Serum total testosterone (TT), sex hormone-binding globulin (SHBG) and free testosterone (FT) were measured. Covariance analysis of different androgen values were performed in age subgroups. Multinomial logistic regression was used for the association of TT, SHBG and FT with prediabetes and diabetes, as well as prediabetes in age subgroups. Results According to ADA new criteria, normoglycemia, prediabetes, and diabetes were diagnosed in 1405, 907 and 342 men, respectively. In covariance analysis, SHBG of prediabetes were found lower than that of normoglycemia but higher than that of diabetes (P prediabetes and diabetes. While, after full adjustment for age, residence area, economic status, waist circumference, metabolic factors, other two androgen values and HOMA-IR, only the associations of SHBG with prevalence of prediabetes and diabetes persisted statistically significant, especially in the elderly with prediabetes (all P for trend prediabetes and diabetes in Chinese men. Low serum SHBG was the most relevant factor for prediabetes and diabetes. Whether it is an independent predictor for incident prediabetes in Chinese men needs further explorations. PMID:27583401

Amaranth 7S globulin is a minor globulin component and its impact on the properties of an amaranth protein ingredient depends on its proportion in the variety of amaranth being considered. Some physicochemical, functional and angiotesin I-converting enzyme (ACE) inhibitory properties of amaranth vicilin were studied in this work and compared with the 11S globulin. Fluorescence spectroscopy results indicated that 7S globulin tryptophans were more exposed to the solvent and, by calorimetry, the 7S globulin denaturation temperature (T(d) ) was found lower than the 11S globulin T(d) , suggesting a more flexible structure. The 7S globulin surface hydrophobicity was higher than that of the 11S globulin, which is in agreement with the better emulsifying properties of the 7S globulin. The solubility in neutral buffer of the 7S globulin (851 ± 25 g kg(-1) ) was also higher than that of the 11S globulin (195 ± 6 g kg(-1) ). Bioinformatic analyses showed the presence of ACE inhibitory peptides encrypted in 7S tryptic sequences and peptides released after in vitro gastrointestinal digestion showed a high ACE-inhibitory capacity (IC(50) = 0.17 g L(-1) ), similar to that of 11S globulin peptides. Compared with the 11S globulin, the 7S globulin presents similar ACE inhibitory activity and some functional advantages, better solubility and emulsifying activity, which suits some food requirements. The functional behavior has been related with the structural properties. Copyright © 2011 Society of Chemical Industry.

Lee, H F; Lee, J D; Lee, Y C

1979-12-01

In course of immunizing horses with snake venoms, tetanus and diphtheria toxoids, a new serum component, T-globulin, was formed and migrated between the beta- and gamma-globulins. The T-globulin content was parallel with the antibody titre after the middle course of immunization. There were many components in snake antivenin and T-globulin was composed of most of those components. The components of diphtheria T-globulin were the same as those of crude antitoxin and tetanus T-globulin except one precipitin.

Objective: To evaluate the association between Sex Hormone Binding Globulin and preeclampsia in Iranian women considering the probable confounding effect of insulin resistance. Methods: The case-control study was conducted at the Semnan University of Medical Sciences, Iran, and comprised pregnant women who received prenatal care at Amiralmomenin Hospital in 2011. Cases represented patients admitted because of preeclampsia, while controls were randomly selected eligible pregnant women without hypertension and/or proteinuria. Fasting blood sugar and insulin were assessed for all participants as well as their blood concentration of Sex Hormone Binding Globulin. The Homeostasis Model Assessment of Insulin Resistance Score was used. The correlation between dependant and independent variables was reported by crude and adjusted odds ratio applying logistic regression models. SPSS 16.0 was used for statistical analysis. Results: Of the 100 pregnant women in the study, 45(45%) were cases. Insulin resistance was found to be significantly more frequent in the cases compared to the controls (adjusted odds ratio=2.78; 95% Confidence Interval: 1.11, 6.90; p<0.01). There was a significant reverse correlation between level of Sex Hormone Binding Globulin in blood and being a case of preeclampsia (adjusted odds ratio=0.99; 95% Confidence Interval: 0.98, 1.00; p=0.04). Conclusion: Independent of insulin resistance, every 1nmol/l increase in Sex Hormone Binding Globulin, decreases the odds of preeclampsia by 1%, notifying Sex Hormone Binding Globulin as an important biomarker about its etiology and prediction.

Aplastic anemia patients who received rabbit antithymocyte globulin exhibited response and survival rates inferior to those who received horse antithymocyte globulin in several studies. Therefore, we conducted a meta-analysis to compare rabbit and horse antithymocyte globulin as immunosuppressive therapy for aplastic anemia. We searched online databases for studies that compared antithymocyte globulin regimens as first-line treatment for aplastic anemia, including both randomized and non-randomized controlled trials. The early mortality rate at 3 months and overall response rate at 6 months were evaluated. Thirteen studies were included in the analysis. The risk ratio (RR) of early mortality for rabbit vs. horse antithymocyte globulin was 1.33 [95% confidence interval (CI) 0.69-2.57; P = 0.39], with significant heterogeneity. A sensitivity analysis suggested higher early mortality rate in patients who received rabbit antithymocyte globulin. The overall response rate was significantly higher in patients who received horse antithymocyte globulin (RR 1.27; 95% CI 1.05-1.54; P = 0.015). In conclusion, in aplastic anemia patients treated with ATG, early mortality rate was not significantly different in patients receiving horse or rabbit ATG, although a sensitivity analysis showed higher early mortality in the rabbit ATG group. Horse ATG was associated with significantly higher response rate than rabbit ATG.

Similarly to unleaded gasoline, 1,4-dichlorobenzene (1,4-DCB) administered for 2 years caused a dose-related increase in the incidence of renal tumors in male but not in female rats or in either sex of mice. Unleaded gasoline and 2,2,4-trimethylpentane (TMP), a component of unleaded gasoline, increased protein droplet formation and cell proliferation in male but not in female rat kidneys. These protein droplets contained, alpha 2u-globulin, a male rat-specific low-molecular-weight protein and 2,4,4-trimethyl-2-pentanol, a metabolite of TMP that was reversibly bound to this protein. Studies were undertaken to determine if 1,4-DCB produced similar effects; 1,2-DCB was used for comparison since it did not produce renal carcinogenesis in male rats. Gel filtration chromatography of a 116,000g supernatant prepared from kidneys of 1,4-[14C]DCB-treated rats showed that radiolabel coeluted with alpha 2u-globulin as one sharp peak as opposed to a multipeak pattern observed for 1,2-[14C]DCB; the maximal quantity of radiolabel for 1,4-DCB was twice that for 1,2-DCB. Equilibrium dialysis of kidney cytosol in the presence or absence of sodium dodecyl sulfate demonstrated that the radiolabel was reversibly bound to alpha 2u-globulin; the amount for 1,4-[14C]DCB-treated rats was almost twice as much as that for 1,2-[14C]DCB-treated rats. 1,2-DCB was also shown to be covalently bound to renal alpha 2u-globulin, and covalently bound to liver and plasma high-molecular-weight proteins. 1,4-DCB and, to a minor extent, 2,5-dichlorophenol, the major metabolite of 1,4-DCB, were reversibly bound to renal alpha 2u-globulin from 1,4-DCB-treated rats. 1,4-DCB increased protein droplet formation in male but not in female rat kidneys, whereas equimolar doses of 1,2-DCB showed no effect in either sex. Renal cell proliferation, measured by [3H]thymidine incorporation into renal DNA, was increased after 1,4-DCB but not after 1,2-DCB treatment. Nephrotoxicity and biochemical alterations induced by

standard-deviation increase in the plasma level of sex hormone–binding globulin was 0.28 (95% CI, 0.13 to 0.58) among women and 0.29 (95% CI, 0.15 to 0.58) among men, a finding that suggests that sex hormone–binding globulin may have a causal role in the risk of type 2 diabetes. CONCLUSIONS Low circulating levels of sex hormone–binding globulin are a strong predictor of the risk of type 2 diabetes in women and men. The clinical usefulness of both SHBG genotypes and plasma levels in stratification and intervention for the risk of type 2 diabetes warrants further examination. PMID:19657112

Human immune serum gamma globulin and rabbit anti-Stap. aureus antibody have been successfully labeled with sup(99m)Tc at pH 7.4 with an average binding efficiency of 86 and 82%, respectively. The labeled proteins behave similarly to unlabeled gamma-globulin fraction in the normal human serum as demonstrated by protein electrophoresis. The biological half-time of sup(99m)Tc-gamma-globulin in dog has been determined to be 54 min for the fast component and 14.7 hr for a slower component. Immunological assays demonstrate no significant change in antibody activity after labeling process. (author)

For treatment of severe aplastic anemia, immunosuppressive therapy with horse antithymocyte globulin results in superior response and survival compared with rabbit antithymocyte globulin. This relative benefit may be different in the setting of transplantation as rabbit antithymocyte globulin results in more profound immunosuppression. We analyzed 833 severe aplastic anemia transplants between 2008 and 2013 using human leukocyte antigen (HLA)-matched siblings (n=546) or unrelated donors (n=287) who received antithymocyte globulin as part of their conditioning regimen and bone marrow graft. There were no differences in hematopoietic recovery by type of antithymocyte globulin.

Globulins-gamma from voluntary blood donors immunized with the Cuban BC antimeningococcus vaccine is now being used in our country for the treatment of the meningococcus disease. This study of the effect of Co-60 irradiation on antimeningococcus globulins-gamma was carried out to try to eliminate the inconvenience shown by the traditionally used sterilization procedures (losses in the filter and persistence of viral contamination). globulins-gamma was obtained by ethanol fractionation and was irradiated at a different dose in solution with different stabilizers and it was also lyophilized. Results of the chemical controls carried out lead to the conclusion that it is possible to use radiosterilization on this product in a lyophilized form. The preservation of bactericidal activity, even after the highest irradiation doses, confirms the above mentioned. 13 refs

Questioning the role of actinfree Gc-Globulin as actin scavenger in neurodegenerative central nervous system disease: relationship to S-100B levels and blood-brain barrier function.

Preliminary studies report on significantly higher levels of the major cytoskeleton protein actin in CSF of patients with neurodegenerative conditions and that the dynamics of these levels obviously correlates with disease progression and clinical disability. One of the primary functions of actinfree Gc-Globulin is to bind and neutralize extracellular monomeric actin, released into the circulation by necrotic or ruptured cells, and thus ameliorating the clinical outcome in situations of severe organ damage. This is the first study to investigate actinfree Gc-Globulin and S100-B levels (as reliable marker of neurodegeneration) in paired CSF and serum samples of patients with multietiological CNS diseases. 42% of all patients with CNS disease displayed serum concentrations of actinfree Gc-Globulin above the established reference range. CSF concentrations of actinfree Gc-Globulin and S100-B were positively correlated with the severity of blood-brain barrier (BBB) dysfunction. Furthermore, patients with severe BBB dysfunction presented a higher percentage of intrathecal synthesis of actinfree Gc-Globulin compared to patients with mild to moderate dysfunction and to patients with normal BBB function. Representative longitudinal data from selected patients demonstrated an inverse behaviour of actinfree Gc-Globulin and S100-B CSF concentrations, suggesting a consumption of the actin scavenger capacity of Gc-Globulin in times of increased neuronal damage. This presumption was supported by the fact that those conditions associated with a severe neuronal damage, in particular CNS trauma, and highest S100-B concentrations simultaneously displayed lowest actinfree Gc-Globulin levels, and thus residual actin binding capacity of Gc-Globulin. In summary, our data propose a function of actinfree Gc-Globulin also in the clearance of actin filaments from CSF of patients with neuronal damage. However, active recruitment of hepatic derived actinfree Gc-Globulin to the site of CNS

A total number of 180 mature rats (120 females and 60 males) weighing from 120-140 g were used to study the effect of two doses (2 and 4 Gy) whole-body gamma irradiation on the level of total protein and protein fractions in serum of pregnant rats during the period of organogenesis. It was found that the levels of total protein, albumin and gamma globulins significantly decreased according to the doses of exposure. The levels of alpha and beta globulins significantly increased more in the serum of rats exposed to 2 Gy than in rats exposed to 4 Gy. The level of A/G ratio significantly decreased more in the serum of rats exposed to 2Gy than in those exposed to 4 Gy

Full Text Available Chickpea seed germination was carried out over a period of 6 days. Little variation in the nitrogen and total globulin content was observed. The major globulin (11 S type showed higher variation after the 4th day of germination. The elution behaviour and distribution of the isolated major globulin fraction on Sepharose CL-6B chromatography showed little modification at the end of germination. On SDS-PAGE the peak eluted from Sepharose CL-6B showed changes in protein bands between 20 and 30 kDa and above 60 kDa, indicating protein degradation during the period. Proteolytic activity was detected in the albumin fraction of the seeds, which increased up to the fourth and then decreased up to the sixth day, when isolated chickpea total globulin and casein were used as substrates. Chickpea flour, isolated albumin and total globulin fractions did not show an increase for in vitro digestibility; however, the isolated major globulin was more susceptible to hydrolysis after germination.A germinação das sementes de grão-de-bico foi acompanhada por um período de 6 dias, no qual pequenas variações nos teores de nitrogênio e globulina total foram registradas.

Durum wheat (Triticum turgidum ssp. durum (Desf.) Husn.) is an economically important crop used for the production of semolina, which is the basis of pasta and other food products. Its grains provide proteins and starch for human consumption. Grain development is a key process in wheat physiology; it is highly affected by a number of enzymes that control the metabolic processes governing accumulation of starch and storage proteins and ultimately grain weight. Most of these enzymes are present in the albumin/globulin grain fraction, which represents about a quarter of total seed proteins. With the aim to describe the dynamic profile of the albumin/globulin fraction during durum wheat grain development, we performed a proteomic analysis of this subproteome using a two-dimensional differential gel electrophoresis (2D-DIGE)-based approach and compared six developmental stages. A total of 285 differentially (237 over- and 48 under-) represented spots was identified by nanoLC-ESI-LIT-MS/MS, which were associated with 217 non-redundant Triticum sequence entries. Quantitative protein dynamics demonstrated that carbon metabolism, energy, protein destination/storage, disease/defense and cell growth/division functional categories were highly affected during grain development, concomitantly with progressive grain size increase and starch/protein reserve accumulation. Bioinformatic interaction prediction revealed a complex network of differentially represented proteins mainly centered at enzymes involved in carbon and protein metabolism. A description of 18 proteins associated with wheat flour human allergies was also obtained; these components showed augmented levels at the last developmental stages. By providing a comprehensive understanding of the molecular basis of durum wheat grain development, yield and quality formation, this study provides the foundation and reveals potential biomarkers for further investigations of durum wheat breeding and semolina quality.

Proteomic analysis is emerging as a highly useful tool in food research, including studies of food allergies. Two-dimensional gel electrophoresis involving isoelectric focusing and sodium dodecyl sulfate polyacrylamide gel electrophoresis is the most effective method of separating hundreds or even thousands of proteins. In this study, albumin and globulin tractions of pea seeds cv. Ramrod were subjected to proteomic analysis. Selected potentially alergenic proteins were identified based on their molecular weights and isoelectric points. Pea seeds (Pisum sativum L.) cv. Ramrod harvested over a period of two years (Plant Breeding Station in Piaski-Szelejewo) were used in the experiment. The isolated albumins, globulins and legumin and vicilin fractions of globulins were separated by two-dimensional gel electrophoresis. Proteomic images were analysed in the ImageMaster 2D Platinum program with the use of algorithms from the Melanie application. The relative content, isoelectric points and molecular weights were computed for all identified proteins. Electrophoregrams were analysed by matching spot positions from three independent replications. The proteomes of albumins, globulins and legumin and vicilin fractions of globulins produced up to several hundred spots (proteins). Spots most characteristic of a given fraction were identified by computer analysis and spot matching. The albumin proteome accumulated spots of relatively high intensity over a broad range of pi values of ~4.2-8.1 in 3 molecular weight (MW) ranges: I - high molecular-weight albumins with MW of ~50-110 kDa, II - average molecular-weight albumins with MW of ~20-35 kDa, and III - low molecular-weight albumins with MW of ~13-17 kDa. 2D gel electrophoregrams revealed the presence of 81 characteristic spots, including 24 characteristic of legumin and 14 - of vicilin. Two-dimensional gel electrophoresis proved to be a useful tool for identifying pea proteins. Patterns of spots with similar isoelectric

A method for the assay of thyroxine-binding globulin on reusable Sephadex G-25 columns is described. It depends upon elution by diluted iodothyronine-free serum of protein-bound [ 125 I]thyroxine from the columns under conditions where binding to thyroxine-binding prealbumin and albumin are abolished. It is simple, rapid and precise, and permits determinations inlarge numbers of samples. Values (mg/l; mean +- S.D.) were: normals 31.6+-5.4, hyperthyroid 28.3+-4.8, hypothyroid 40.6+-7.5, oral contraceptives 40.1+-6.8, pregnant 50.3+-5.4, cirrhotics 20.7+-4.3. Concentrations were reduced in serum heated at 56degC, while the uptake of [ 125 I]triiodothyronine was increased. There was a significant negative correlation between thyroxine-binding globulin concentration and triiodothyronine uptake in the heated serum samples and in euthyroid subjects

Trends in shortages of vaccines and immune globulin products from 2001 through 2015 in the United States are described. Drug shortage data from January 2001 through December 2015 were obtained from the University of Utah Drug Information Service. Shortage data for vaccines and immune globulins were analyzed, focusing on the type of product, reason for shortage, shortage duration, shortages requiring vaccine deferral, and whether the drug was a single-source product. Inclusion of the product into the pediatric vaccination schedule was also noted. Of the 2,080 reported drug shortages, 59 (2.8%) were for vaccines and immune globulin products. Of those, 2 shortages (3%) remained active at the end of the study period. The median shortage duration was 16.8 months. The most common products on shortage were viral vaccines (58%), especially hepatitis A, hepatitis B, rabies, and varicella vaccines (4 shortages each). A vaccine deferral was required for 21 shortages (36%), and single-source products were on shortage 30 times (51%). The most common reason for shortage was manufacturing problems (51%), followed by supply-and-demand issues (7%). Thirty shortages (51%) were for products on the pediatric schedule, with a median duration of 21.7 months. Drug shortages of vaccines and immune globulin products accounted for only 2.8% of reported drug shortages within a 15-year period, but about half of these shortages involved products on the pediatric vaccination schedule, which may have significant public health implications.

The relationship of cigarette smoking, age, total testosterone free testosterone and sex hormone binding globulin (SHBG) were examined by solid phase radioimmunoassay in 90 randomly chosen healthy males of different ages. The serum levels of these hormones were investigated for smokers compared with non-smokers, of the same ages in 3 groups (adolescent males, middle aged males, and old aged males). Results indicated that cigarette smokers showed increased serum levels of testosterone (60.0% higher, P> 0.05), free testosterone (51.0 higher, P > 0.005) in young adolescent males group, testosterone (27.8% higher, P > 0.001), free testosterone (21.3% higher, P > 0.001) in middle aged males group, and testosterone (21.0% higher, P > 0.001), free testosterone (16.8% higher, P > 0.4) in old ages males group. SHBG was calculated as a mean of free and total testosterone in each group. smokers showed higher mean values of SHBG than non-smokers. Age was positively associated with serum SHBG, it was found that SHBG increased by 17.2% from the youngest (> 18 years) to the oldest age (> 65 years)

Corticosteroid-binding globulin (CBG) is a plasma protein that binds corticosterone and may regulate access of hormone to tissues. The role of CBG during a stress response is not clear. In this study, southern toads, Bufo terrestris, were exposed to a chronic pollutant (coal-combustion-waste), to determine changes in CBG and free corticosterone levels. Since toads exposed to chronic pollutants in previous studies did not exhibit the predicted changes in metabolic rate and mass, but did experience a significant elevation in total corticosterone, we hypothesized that CBG would likewise increase and thus, mitigate the effects of a chronic (i.e. 2 months) pollutant stressor. To conduct this study, we first characterized the properties of CBG in southern toads. After characterization, we monitored the changes in CBG, total corticosterone, and free corticosterone in male toads that were exposed to either coal-combustion-waste or control conditions. CBG increased in all groups throughout the experiment. Total corticosterone, on the other hand, was only significantly elevated at four weeks of exposure to coal-combustion-waste. The increase in CBG did not parallel the increase in total corticosterone; as a result, free corticosterone levels were not buffered by CBG, but showed a peak at four weeks similar to total corticosterone. This finding indicates that, in this species, CBG may not provide a protective mechanism during long-term pollution exposure.

Electron micrographs of isolated human alpha(2)M-molecules, obtained by the negative contrast technique, revealed morphologically homogenous structures resembling a graceful monogram of the two letters H and I. The modal values for the length and width of the alpha(2)M particles were 170 A and 100 A, respectively. Purified rabbit alphamacroglobulins contained about 80% alpha(1)M- and 20% alpha(2)M-globulins. The isolated rabbit alpha(1)M- and alpha(2)M-molecules were morphologically indistinguishable from one another and from human alpha(2)M-molecules. Preliminary immunoprecipitation studies demonstrated that the two rabbit alphaM-globulins were antigenically different. Sedimentation constant determinations gave s(20, w) values of 18.8 and 18.2 for rabbit alpha(1)M and alpha(2)M, respectively.

Lack of Globulin Synthesis during Seed Development Alters Accumulation of Seed Storage Proteins in Rice

Directory of Open Access Journals (Sweden)

Hye-Jung Lee

2015-06-01

Full Text Available The major seed storage proteins (SSPs in rice seeds have been classified into three types, glutelins, prolamins, and globulin, and the proportion of each SSP varies. It has been shown in rice mutants that when either glutelins or prolamins are defective, the expression of another type of SSP is promoted to counterbalance the deficit. However, we observed reduced abundances of glutelins and prolamins in dry seeds of a globulin-deficient rice mutant (Glb-RNAi, which was generated with RNA interference (RNAi-induced suppression of globulin expression. The expression of the prolamin and glutelin subfamily genes was reduced in the immature seeds of Glb-RNAi lines compared with those in wild type. A proteomic analysis of Glb-RNAi seeds showed that the reductions in glutelin and prolamin were conserved at the protein level. The decreased pattern in glutelin was also significant in the presence of a reductant, suggesting that the polymerization of the glutelin proteins via intramolecular disulfide bonds could be interrupted in Glb-RNAi seeds. We also observed aberrant and loosely packed structures in the storage organelles of Glb-RNAi seeds, which may be attributable to the reductions in SSPs. In this study, we evaluated the role of rice globulin in seed development, showing that a deficiency in globulin could comprehensively reduce the expression of other SSPs.

Rebalance between 7S and 11S globulins in soybean seeds of differing protein content and 11SA4.

Protein content and globulin subunit composition of soybean seeds affect the quality of soy foods. In this proteomic study, the protein profile of soybean seeds with high (∼45.5%) or low (∼38.6%) protein content and with or without the glycinin (11S) subunit 11SA4 was examined. 44 unique proteins and their homologues were identified and showed that both protein content and 11SA4 influenced the abundance of a number of proteins. The absence of 11SA4 exerted a greater impact than the protein content, and led to a decreased abundance of glycinin G2/A2B1 and G5/A5A4B3 subunits, which resulted in lower total 11S with a concomitant higher total β-conglycinin (7S). Low protein content was associated with higher glycinin G3/A1aB1b and lower glycinin G4/A5A4B3. Using the proteomic approach, it was demonstrated that 11SA4 deficiency induced compensatory accumulation of 7S globulins and led to a similar total abundance for 7S+11S irrespective of protein content or 11SA4.

Patients taking hydrocortisone (HC) replacement for primary or secondary adrenal failure require individual adjustment of their dose. In addition to modifying the administered doses of HC for each patient, physicians are increasingly interested in variations in the bioavailability of glucocorticoid replacement. One potential determinant of the bioavailability of replaced HC is a variation in serum cortisol-binding globulin (CBG) concentration, which may, in turn, affect interpretation of cortisol profiles and individual dose selection for patients on hydrocortisone replacement therapy. To investigate the hypothesis that there is a circadian variation in CBG levels. A total of 34 male patients divided into 3 groups (10 patients with non-somatotroph structural pituitary disease on HC replacement, 11 patients with treated acromegaly on HC replacement and 13 patients with treated acromegaly not on HC replacement) and 10 healthy volunteers were included. Cortisol and CBG levels were measured at 6 time points (0800, 1100, 1300, 1500, 1700 and 1900). No significant circadian variation in CBG concentration was found in any of the 4 groups. Circadian variation in serum cortisol during hydrocortisone replacement is not attributable to changes in cortisol-binding globulin concentration. Changes in serum cortisol levels may thus be explained by other factors including 11 β-hydroxysteroid dehydrogenase type 1 activity or circadian changes in the binding properties of CBG. © 2015 John Wiley & Sons Ltd.

Radioimmunoassay of testosterone and of sexual hormone-binding globulin in plasma of women with hirsutism

International Nuclear Information System (INIS)

Warenik-Szymankiewicz, A.; Baron, J.; Chawlisz, K.

1980-01-01

Plasma-borne testosterone was determined in 176 women with hirsutism, and in 47 patients sexual hormone-binding globulin was determined as well. The highest average testosterone values were recorded from cases with congenital adrenogenital syndrome (AGS). In cases of postnatal AGS values were much lower, but they were clearly in excess of those recordable from Stein-Leventhal syndrome. Plasma borne testosterone in cases of hirsutism came very close to testosterone levels established in the context of Stein-Leventhal syndrome. Testosterone levels dropped with significance, following AGS treatment, using cortisol derivatives, and following wedge-shaped ovariectomy. Sexual hormone binding-globulin was found to be strongly reduced in almost all women with hirsutism. Such reduction seemed to suggest the presence of increased amounts of free active testosterone in the blood of those patients. Determination of plasma-borne testosterone in cases of hirsutism is considered to be essential to both diagnosis of the endocrinological syndromes and monitoring of therapy. (author)

Anti-T lymphocyte globulin (ATLG) modulates the alloreactivity of T lymphocytes, reducing the risk of immunological posttransplant complications, in particular rejection and graft-versus-host disease, after allogeneic hematopoietic stem cell transplantation (HSCT). We developed and validated a new enzyme-linked immunosorbent assay (ELISA) method to measure serum levels of total ATLG and evaluate the pharmacokinetics (PK) of the drug in children with β-Thalassemia, receiving allogeneic HSCT. Diluted serum samples were incubated with Goat-anti-Rabbit IgG antibody coated on a microtiter plate and then, with Goat-anti-Human IgG labeled with horseradish peroxidase. After incubation and washings, substrate solution was added and absorbance was read at 492 nm. ATLG concentrations in samples were determined by interpolation from a standard curve (range: 200-0.095 ng/mL), prepared by diluting a known amount of ATLG in phosphate-buffered saline (PBS). Low, medium, and high-quality control concentrations were 1.56, 6.25, and 25 ng/mL, respectively. This method was developed and validated within the acceptance criteria in compliance with the Guidelines for a biological method validation: the sensitivity of the method was 0.095 ng/mL. We analyzed serum samples from 14 children with β-Thalassemia who received ATLG (Grafalon) at a dose of 10 mg/kg administered as intravenous (IV) infusion on days -5, -4, and -3 before HSCT (day 0). Blood sampling for PK evaluation was performed on days -5, -4, and -3 before and after drug infusion; and then from day -2 to +56. The median total ATLG levels pre-IVand post-IV were 0 and 118 mcg/mL on day -5; 85.9 and 199.2 mcg/mL on day -4; 153 and 270.9 mcg/mL on day -3, respectively. The median PK values of CL was 0.0029 (range: 0.0028-0.0057) L·kg·d, Vd was 0.088 (range: 0.025-0.448) L/kg and t1/2 was 20.2 (range: 5.8-50.2) days. These data suggest that given the marked interindividual variability of total ATLG disposition, the development of

Human sex hormone binding globulin (SHBG) is encoded by a normal and a variant allele. The resulting SHBG phenotypes (the homozygous normal SHBG, the heterozygous SHBG and the homozygous variant SHBG phenotype) can be distinguished by their electrophoretic patterns. We developed a novel detection....... This method of detection was used to determine the distribution of SHBG phenotypes in healthy controls of both sexes and in five different pathological conditions characterized by changes in the SHBG level or endocrine disturbances (malignant and benign ovarian neoplasms, hirsutism, liver cirrhosis...... on the experimental values. Differences in SHBG phenotypes do not appear to have any clinical significance and no sex difference was found in the SHBG phenotype distribution....

Low levels of sex hormone-binding globulin and hyperproinsulinemia as markers of increased pancreatic ß-cell demand in men

Directory of Open Access Journals (Sweden)

1998-12-01

Full Text Available Low levels of sex hormone-binding globulin (SHBG are considered to be an indirect index of hyperinsulinemia, predicting the later onset of diabetes mellitus type 2. In the insulin resistance state and in the presence of an increased pancreatic ß-cell demand (e.g. obesity both absolute and relative increases in proinsulin secretion occur. In the present study we investigated the correlation between SHBG and pancreatic ß-cell secretion in men with different body compositions. Eighteen young men (30.0 ± 2.4 years with normal glucose tolerance and body mass indexes (BMI ranging from 22.6 to 43.2 kg/m2 were submitted to an oral glucose tolerance test (75 g and baseline and 120-min blood samples were used to determine insulin, proinsulin and C-peptide by specific immunoassays. Baseline SHBG values were significantly correlated with baseline insulin (r = -0.58, P28 kg/m2, N = 8 and nonobese (BMI £25 kg/m2, N = 10 groups, significantly lower levels of SHBG were found in the obese subjects. The obese group had significantly higher baseline proinsulin, C-peptide and 120-min proinsulin and insulin levels. For the first time using a specific assay for insulin determination, a strong inverse correlation between insulinemia and SHBG levels was confirmed. The finding of a strong negative correlation between SHBG levels and pancreatic ß-cell secretion, mainly for the 120-min post-glucose load proinsulin levels, reinforces the concept that low SHBG levels are a suitable marker of increased pancreatic ß-cell demand.

The pronounced fragility that characterizes swine erythrocytes is likely to produce a variable degree of hemolysis during blood sampling, and the free hemoglobin may then unpredictably bias the quantification of several analytes. The aim of this study was to evaluate the degree of acceptability of values obtained for several biochemical parameters at different levels of hemolysis. Progressively increased degrees of physical hemolysis were induced in 3 aliquots of 30 nonhemolytic sera, and the relative effects on the test results were assessed. To define the level of hemolysis, we used both visual estimation (on a scale of 0 to 3+) and analytical assessment (hemolytic index) and identified the best analytical cutoff values for discriminating the visual levels of hemolysis. Hemolysis led to a variable and dose-dependent effect on the test results that was specific for each analyte tested. In mildly hemolyzed specimens, C-reactive protein, haptoglobin, β1-globulin, β2-globulin, α1-globulin, γ-globulin, sodium, calcium, and alkaline phosphatase were not significantly biased, whereas α2-globulin, albumin, urea, creatinine, glucose, total cholesterol, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transferase, nonesterified fatty acids, bilirubin, phosphorus, magnesium, iron, zinc, copper, lipase, triglycerides, lactate dehydrogenase, unbound iron-binding capacity, and uric acid were significantly biased. Chloride and total protein were unbiased even in markedly hemolyzed samples. Analytical interference was hypothesized to be the main source of this bias, leading to a nonlinear trend that confirmed the difficulty in establishing reliable coefficients of correction for adjusting the test results. © 2015 The Author(s).

Full Text Available Nonmyeloablative (NMA conditioning with total lymphoid irradiation and antithymocyte globulin (TLI/ATG has been shown to protect against acute graft-versus-host disease (GVHD. We report here our institutional experience with allogeneic transplantation following NMA conditioning with TLI/ATG (. GVHD prophylaxis consisted of a combination of a calcineurin inhibitor and mycophenolate mofetil. Median patient age was 59 years. The median followup of surviving patients is 545 days. One patient experienced primary graft rejection. The median time to neutrophil engraftment was 18 days and platelet engraftment was 9.5 days. The cumulative incidence (CI of grade II–IV acute GVHD at day +100 was 28.6% and 38.1% at day +180. The CI for grade III-IV acute GVHD was 28.6% at day +180. CI of chronic GVHD was 45.2% at 1 year. The CI of disease relapse was 9.5% at 1 year. The rate of nonrelapse mortality (NRM was 0% at day +100 and only 9.5% at 1 year. The overall and progression free survival at 1 year was 81% and 80.4%, respectively. Our limited, retrospective data show encouraging relapse and NRM rates with TLI/ATG-based NMA conditioning, but with higher than previously reported rates of acute and chronic GVHD, underscoring the need for novel strategies designed to effectively prevent GVHD.

THE EFFECTS OF COPPER AND ZINC IONS DURING THEIR BINDING WITH HUMAN SERUM γ-GLOBULIN

Full Text Available Abstract. Conformational changes of human serum γ-globulin were studied during and after its binding with copper and zinc ions, using molecular ultrafiltration and differential spectrophotometry. The contents of nonbound metals in the filtrate were evaluated, resp., with sodium diethyl thyocarbamate and o-phenanthroline. It has been shown that copper and zinc exhibited common biological properties during their interactions with protein, but the binding differed sufficiently under similar experimental conditions. E.g., it was confirmed that copper was more active at the external sites of γ-globulin molecule, whereas zinc demonstrated tropicity for the areas of protein intraglobular compartments. The metal-binding sites have been described that differ in their parameters of interactions with cations and their spatial location within globular domains. Approaches are suggested for dynamic analysis of saturation for these differently located sites by the metal ions. We discuss the issues of altered conformational state of the γ-globulin molecule during the binding of cations, as well as potential usage of these data in clinical immunology.

1989-01-01

A high serum cortisol concentration, apparently due to increased cortisol-binding globulin (CBG), was found in a patient (index case) with chronic active hepatitis (CAH). We therefore performed further studies to determine whether increased cortisol binding is generally associated with CAH. Serum samples were obtained from 15 hospitalized patients with long-term liver function test elevations but no evidence of cirrhosis, 15 normal subjects without a history of hepatitis, four healthy pregnant women, and 10 alcoholic patients with stigmata of cirrhosis. Serum cortisol binding was measured by an adaptation of a previously described charcoal uptake method. Thyroxine-binding globulin (TBG) and sex hormone-binding globulin were determined by radioimmunoassays. Charcoal uptake of 125I cortisol from sera of normal subjects and additional patients with CAH revealed that increased serum cortisol binding by a saturable site, presumably CBG, was associated with CAH. Cortisol binding was significantly correlated with immunoassayable TBG, suggesting that in CAH, similar mechanisms may be responsible for increasing the serum concentrations of CBG and TBG

Obesity, insulin resistance, and weight loss have been associated with changes in hypothalamic-pituitary-adrenal (HPA) axis. So far, no conclusive data relating to this association are available. In this study, we aim to investigate the effects of massive weight loss on cortisol suppressibility, cortisol-binding globulin (CBG), and free cortisol index (FCI) in formerly obese women. Ten glucose-normotolerant, fertile, obese women (BMI >40 kg/m2, aged 38.66 +/- 13.35 years) were studied before and 2 years after biliopancreatic diversion (BPD) when stable weight was achieved and were compared with age-matched healthy volunteers. Cortisol suppression was evaluated by a 4-mg intravenous dexamethasone suppression test (DEX-ST). FCI was calculated as the cortisol-to-CBG ratio. Insulin sensitivity was measured by an euglycemic-hyperinsulinemic clamp, and insulin secretion was measured by a C-peptide deconvolution method. No difference was found in cortisol suppression after DEX-ST before or after weight loss. A decrease in ACTH was significantly greater in control subjects than in obese (P = 0.05) and postobese women (P obese subjects, an increase of free cortisol was associated with a simultaneous decrease in CBG levels, which might be an adaptive phenomenon relating to environmental changes. This topic, not addressed before, adds new insight into the complex mechanisms linking HPA activity to obesity.

Clinical outcomes after hepatitis C infection from contaminated anti-D immune globulin. Irish Hepatology Research Group.

2012-02-03

BACKGROUND AND METHODS: In February 1994, batches of anti-D immune globulin used in Ireland during 1977 and 1978 to prevent Rh isoimmunization were found to be contaminated with hepatitis C virus (HCV) from a single infected donor. In March 1994, a national screening program was initiated for all women who had received anti-D immune globulin between 1970 and 1994. Of the 62,667 women who had been screened when this study began, 704 (1.1 percent) had evidence of past or current HCV infection, and 390 of those 704 (55 percent) had positive tests for serum HCV RNA on reverse-transcription-polymerase-chain-reaction analysis. All 390 were offered a referral for clinical assessment and therapy. We evaluated 376 of these 390 women (96 percent); the other 14 were not seen at one of the designated treatment centers. RESULTS: The mean (+\\/-SD) age of the 376 women was 45+\\/-6 years at the time of screening. They had been infected with hepatitis C for about 17 years. A total of 304 women (81 percent) reported symptoms, most commonly fatigue (248 [66 percent]). Serum alanine aminotransferase concentrations were slightly elevated (40 to 99 U per liter) in 176 of 371 women (47 percent), and the concentrations were 100 U per liter or higher in 31 (8 percent). Liver biopsies showed inflammation in 356 of 363 women (98 percent); in most cases the inflammation was slight (41 percent) or moderate (52 percent). Although the biopsy samples from 186 of the 363 women (51 percent) showed evidence of fibrosis, only 7 women (2 percent) had probable or definite cirrhosis. Two of the seven reported excessive alcohol consumption. CONCLUSIONS: Most of the women with HCV infection 17 years after receiving HCV-contaminated anti-D immune globulin had evidence of slight or moderate hepatic inflammation on liver biopsy, about half had fibrosis, and 2 percent had probable or definite cirrhosis.

To investigate whether total antioxidant capacity (TAC) could predict the response to ovulation induction to clomiphene citrate (CC) in nonobese women with polycystic ovary syndrome. Prospective longitudinal follow-up study. Academic hospital. Fifty-five nonobese, oligomenorrheic women with polycystic ovary syndrome and normal indices of insulin sensitivity. None. Standard clinical examinations and ultrasonographic and endocrine screening, including FSH, LH, E(2), P, total T, sex hormone-binding globulin, DHEAS, and TAC were performed before initiation of CC medication. Within the total group, 27 (49%) of the patients did not ovulate at the end of follow-up. TAC, free androgen index, and ovarian volume were all significantly different in CC nonresponders from those in responders. Total antioxidant capacity was found to be the best predictor in univariate analysis (odds ratio, 171.55; 95% confidence interval, 10.61-2,772.93), and it had the highest area in the receiver operating characteristics analysis (0.91). In a multivariate prediction model, TAC, free androgen index, and ovarian volume showed good predictive power, with Hosmer-Lemeshow goodness of fit test of 0.80. Total antioxidant capacity was the strongest predictor of ovarian response during CC induction of ovulation in these patients. It can be concluded that TAC can be used as a routine screening test.

Full Text Available CONTEXT AND OBJECTIVE: Metabolic syndrome consists of a set of factors that imply increased risk of cardiovascular diseases. The objective here was to evaluate the association between sex hormone-binding globulin (SHBG, sex hormones and metabolic syndrome among men. DESIGN AND SETTING: Retrospective analysis on data from the study "Endogenous oestradiol but not testosterone is related to coronary artery disease in men", conducted in a hospital in São Paulo. METHODS: Men (aged 40-70 who underwent coronary angiography were selected. The age, weight, height, waist circumference, body mass index and prevalence of dyslipidemia, hypertension and diabetes of each patient were registered. Metabolic syndrome was defined in accordance with the criteria of the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation and Treatment of High Blood Cholesterol in Adults (NCEP-ATPIII. Serum samples were collected to assess the levels of glucose, total cholesterol, HDL-cholesterol (high density lipoprotein, triglycerides, albumin, SHBG, estradiol and total testosterone (TT. The levels of LDL-cholesterol (low density lipoprotein were calculated using Friedewald's formula and free testosterone (FT and bioavailable testosterone (BT using Vermeulen's formula. RESULTS: 141 patients were enrolled in the study. The prevalence of metabolic syndrome was significantly higher in the first SHBG tercile than in the second and third terciles. A statistically significant positive association between the SHBG and TT values was observed, but no such association was seen between SHBG, BT and FT. CONCLUSION: Low serum levels of SHBG are associated with higher prevalence of metabolic syndrome among male patients, but further studies are required to confirm this association.

d-Limonene is a naturally occurring monoterpene, which when dosed orally, causes a male rat-specific nephrotoxicity manifested acutely as the exacerbation of protein droplets in proximal tubule cells. Experiments were conducted to examine the retention of [ 14 C]d-limonene in male and female rat kidney, to determine whether d-limonene or one or more of its metabolites associates with the male rat-specific protein, alpha 2u-globulin, and if so, to identify the bound material. The results indicated that, 24 hr after oral administration of 3 mmol d-limonene/kg, the renal concentration of d-limonene equivalents was approximately 2.5 times higher in male rats than in female rats. Equilibrium dialysis in the presence or absence of sodium dodecyl sulfate indicated that approximately 40% of the d-limonene equivalents in male rat kidney associated with proteins in a reversible manner, whereas no significant association was observed between d-limonene equivalents and female rat kidney proteins. Association between d-limonene and male rat kidney proteins was characterized by high-performance gel filtration and reverse-phase chromatography. Gel filtration HPLC indicated that d-limonene in male rat kidney is associated with a protein fraction having a molecular weight of approximately 20,000. Separation of alpha 2u-globulin from other kidney proteins by reverse-phase HPLC indicated that d-limonene associated with a protein present only in male rat kidney which was definitively identified as alpha 2u-globulin by amino acid sequencing. The major metabolite associated with alpha 2u-globulin was d-limonene-1,2-oxide. Parent d-limonene was also identified as a minor component in the alpha 2u-globulin fraction

Immune Thrombocytopenia (ITP) is characterised by an autoimmune antibody-mediated destruction of platelets and impaired platelet production. Few controlled trials exist to guide management of patients with ITP in Indian scenario for which patients require an individualized approach. Anti-D (Rho (D) immune globulin) at a higher dose can prove to be a cost effective and safe alternative for Indian patients with ITP. To compare the safety and efficacy of higher dose (75μg/kg) intravenous Anti-D immune globulin against the standard dose of 50μg/kg for the management of ITP in Indian patients. One hundred and sixty four children with newly diagnosed ITP between 4-14 years were randomly selected for inclusion and were treated with 50μg/kg (standard dose) or 75μg /kg (higher dose) of Anti-D to compare the efficacy and safety of higher dose intravenous anti-D immune globulin. Efficacy of Anti-D was measured in terms of rate of response and median time to response for increase in platelet counts. Any adverse event was noted. A decrease in haemoglobin concentration suggested accompanying haemolysis. Seventy one out of 84 patients treated with Anti-D at 75μg/kg produced complete response (85%) with median time of response being 2.5 days. On the contrary, 45 patients (70%) patients treated with 50μg/kg had complete response. However, there was no significant increase in haemolysis with higher dose. A significant correlation was found between dose and peak increase in platelet count measured at 7 th day following administration. However, there was no relationship between the decrease in haemoglobin and the dose given, or between the increase in platelet count and fall in haemoglobin. A 75μg/kg dose of Anti-D is more effective with acceptable side effect in comparison to 50μg dose for treatment of newly diagnosed Indian patients of ITP.

Antithymocyte Globulin Induces a Tolerogenic Phenotype in Human Dendritic Cells

Tobias Roider

2016-12-01

Full Text Available Antithymocyte globulin (ATG is used in the prevention of graft-versus-host disease during allogeneic hematopoietic stem cell transplantation. It is generally accepted that ATG mediates its immunosuppressive effect primarily via depletion of T cells. Here, we analyzed the impact of ATG-Fresenius (now Grafalon® on human monocyte-derived dendritic cells (DC. ATG induced a semi-mature phenotype in DC with significantly reduced expression of CD14, increased expression of HLA-DR, and intermediate expression of CD54, CD80, CD83, and CD86. ATG-DC showed an increase in IL-10 secretion but no IL-12 production. In line with this tolerogenic phenotype, ATG caused a significant induction of indoleamine 2,3-dioxygenase expression and a concomitant increase in levels of tryptophan metabolites in the supernatants of DC. Further, ATG-DC did not induce the proliferation of allogeneic T cells in a mixed lymphocyte reaction but actively suppressed the T cell proliferation induced by mature DC. These data suggest that besides its well-known effect on T cells, ATG modulates the phenotype of DC in a tolerogenic way, which might constitute an essential part of its immunosuppressive action in vivo.

2016-04-06

The present work investigates the formation of protein aggregates (85 °C, 60 min incubation) upon heat treatment of β-lactoglobulin (βlg)-pea globulins (Glob) mixtures at pH 7.2 and 5 mM NaCl from laboratory-prepared protein isolates. Various βlg/Glob weight ratios were applied, for a total protein concentration of 2 wt % in admixture. Different analytical methods were used to determine the aggregation behavior of "mixed" aggregates, that is, surface hydrophobicity and also sulfhydryl content, protein interactions by means of SDS-PAGE electrophoresis, and molecule size distribution by DLS and gel filtration. The production of "mixed" thermal aggregates would involve both the formation of new disulfide bonds and noncovalent interactions between the denatured βlg and Glob subunits. The majority of "mixed" soluble aggregates displayed higher molecular weight and smaller diameter than those for Glob heated in isolation. The development of pea-whey protein "mixed" aggregates may help to design new ingredients for the control of innovative food textures.

The aim of this study was to clarify the effect of low and high dietary protein on some biochemical and hematological parameters in blood of female albino rats. A total number of 75 albino female rats were equally divided into 3 groups, the first group was fed 20% protein diet and served as control and the second and third groups were fed 5% and 65% protein for 5 weeks and served as low and high protein dietary groups, respectively. The results showed high significant decreases in serum growth hormone, ferritin levels and iron concentration in group II and there was significant increase in unsaturated iron binding capacity (UIBC) in group III, compared to control group. Studies of total protein and its fractions revealed high significant decreases in total protein, albumin, alpha-1-globulin, beta-globulin as well as gamma globulin in group II and significant increases in total protein, alpha-1- globulin, beta-globulin and gamma-globulin in group III, compared to normal control group. The hematological investigations in group II revealed significant decreases in hemoglobin value, total leukocyte count, platelets, mean corpuscular hemoglobin concentration (MCHC), erythrocytic count and mean corpuscular volume (MCV). On the other hand, there was significant increase in total leukocyte count in group III if compared to control group

Liappis, N.; Hoffmann, U.; Rao, M.L.

1986-01-01

The concentrations of triiodothyronine, thyroxine, thyrotropin and thyroxine-binding globulin were determined in fasting serum from 11 healthy men (age 18-25 years) by radioimmunoassays conducted over a period of 4 weeks on 5 consecutive days per week. The concentrations of thyroxine and thyroxine-binding globulin were very consistent intraindividually, with coefficients of variation of 7.84% and 9.37%, respectively. The triiodothyronine and thyrotropin levels showed significant intraindividual variability with coefficients of variation of 18.38% and 51.85%, respectively. These results point to the type of difficulties encountered in judging serum values, namely intraindividual variations over a given period of time. (orig.) [de

11S Storage globulin from pumpkin seeds: regularities of proteolysis by papain.

Rudakova, A S; Rudakov, S V; Kakhovskaya, I A; Shutov, A D

2014-08-01

Limited proteolysis of the α- and β-chains and deep cleavage of the αβ-subunits by the cooperative (one-by-one) mechanism was observed in the course of papain hydrolysis of cucurbitin, an 11S storage globulin from seeds of the pumpkin Cucurbita maxima. An independent analysis of the kinetics of the limited and cooperative proteolyses revealed that the reaction occurs in two successive steps. In the first step, limited proteolysis consisting of detachments of short terminal peptides from the α- and β-chains was observed. The cooperative proteolysis, which occurs as a pseudo-first order reaction, started at the second step. Therefore, the limited proteolysis at the first step plays a regulatory role, impacting the rate of deep degradation of cucurbitin molecules by the cooperative mechanism. Structural alterations of cucurbitin induced by limited proteolysis are suggested to generate its susceptibility to cooperative proteolysis. These alterations are tentatively discussed on the basis of the tertiary structure of the cucurbitin subunit pdb|2EVX in comparison with previously obtained data on features of degradation of soybean 11S globulin hydrolyzed by papain.

Spatial and temporal dynamics of corticosterone and corticosterone binding globulin are driven by environmental heterogeneity.

2008-02-01

The question of whether changes in glucocorticoid concentrations reflect consistent changes in physiology associated with transitions between different stages of reproduction, or whether they reflect responses to environmental conditions, is one the central issues in field endocrinology studies. We examined the temporal and spatial dynamics of corticosterone (CORT, baseline, and acute stress-induced) and corticosterone binding globulin (CBG) concentrations in blood of Black-legged Kittiwakes (Rissa tridactyla) breeding at four major colonies in the Bering Sea, Alaska, during 1999-2005. We found that total CORT, free CORT, and CBG capacity varied inconsistently among reproductive stages, colonies, and years. Total CORT levels were positively correlated with CBG capacity. Variation in free CORT was largely driven by variation in total CORT. Results suggest that the adrenocortical function and CBG in breeding kittiwakes do not vary as a consequence of stage-specific modulation associated with a particular reproductive stage as in some short-lived passerine birds. Rather, in accord with predictions for a long-lived species, the lack of consistent colony, year, and reproductive stage patterns in baseline and maximum CORT, and CBG indicates that environmental factors, probably local dynamics of food availability, drive variation in these factors.

Isolation of the corticosteroid-binding globulin CBG was achieved by 5 chromatographical steps on cortisol Sepharose, QAE-Sephadex A-50, Con A-Sepharose and hydroxylapatite. The purity of the isolated CBG was demonstrated in polyacrylamide gel electrophoresis, SDS electrophoresis, immunodiffusion and ultracentrifugation. Microheterogeneity was shown in isoeletric focusing by 5 bands in the pH range of 3.7-4.2, which could be reduced to one major band after neuraminidase treatment. The equimolar binding of cortisol to CBG was demonstrated by binding studies. The association constant for cortisol was 2.8 x 10 8 M -1 , for progesterone 1.7 x 10 6 M -1 . From analytical ultracentrifugation, the molecular weight was calculated on 50 700; the sedimentation coefficient was 3.6 S, the partial specific volume 0.690 ml/g, the Stokes radius 38 A and the frictional coefficient ratio 1.5. A specific radioimmunoassay for CBG was established using the purified CBG for immunization, radioiodination and for calibration standards. The normal range of CBG levels in human serum was 2.4-4.4 mg/100 ml (mean +- 2SD). Studies were performed to compare the levels of CBG and thyroxine-binding globulin (TBG). No sex differences but a significant biphasic age dependence were observed for both proteins. In pregnancy and under oestrogen treatment of women and men, CBG was demonstrated to be the more distinct indicator of oestrogenic activity as compared with TBG, whereas the sensitivity of TBG was more pronounced to supposedly antioestrogenic substances like Danazol, and in severe disease. No coincidence of genetic CBG and TBG deficiencies have been found so far. (author)

Full Text Available The effects of various ionic strengths and protein concentrations on the fibrils structure and gel properties of rice bran globulin (RBG at pH 2.0 were investigated using atomic force microscopy (AFM, rheometer, and scanning electron microscope (SEM. AFM images showed the morphology of assembling RBG fibrils from strand beads to becoming branch clustered, when electrostatic repulsive forces attenuated gradually with increasing ionic strength. NaCl seems to accelerate the kinetics of fibrils formation, resulting in a significant increase in Th T fluorescence intensity. The increased ionic strengths promote particle size increasing and zeta potential decreasing synchronously. The percolation model G'~C-Cpn be used to calculate theoretical RBG gels concentration at various ionic strengths (0–500 mM, which decreased from 15.17 ± 0.63 to 2.26 ± 0.27 wt%. SEM images exhibited a granular mesh-like gel structure. A more homogenous structure occurred in low ionic strength. This study elucidates properties of RBG fibrils and gels as a bioactive material.

Objective: To study the oral health effect of long term low dose radiation on exposure personnel and to provide a basis for further improving the protection ability. Methods: Testing method, which was based on APT and HSA interactions induced by synchronous fluorescence specific changes, and intensity and concentrations of HSA in the solution in the system of synchronous fluorescence showed a good linear relations. the establishment of a APT as a molecular probe was used to test concentration of salivary total protein (TP), albumin (ALB), globulin (GLO) and albumin by synchronous fluorescence spectrum analysis. The information was analyzed in Foxpro 6.0 and SPSS 16.0 software. Result: Protein (TP) Mean Value was 3.904 ±1.369 g/L, Minimum Value was 0.30 g/L and Maximum Value was 7.50 g/L. Albumin (ALB) Mean Value was 0.965±0.665 g/L, Minimum Value was 0.09 g/L and Maximum Value was 3.98 g/L. Globulin (GLO) Mean Value was 2.895±0.947 g/L, Minimum Value was 0.01 g/L and Maximum Value was 5.81 g/L. A/G Mean Value was 0.327. Conclusion: Long term and low dose of radiation would break the chronic physiological balance and concentration of salivary total protein (TP), albumin (ALB), globulin (GLO) and albumin and globulin ratio (A/G) changed obviously. It was necessary to do more special oral health care, further improve the individual protection consciousness, strengthen the radiation monitoring and protection measures, improve the regulation system, and reduce radiation damage on special personnel health significantly.

To assess the efficacy of the yeast-recombinant vaccine, the authors administered the vaccine in combination with hepatitis B immune globulin to high-risk newborns. If infants whose mothers were positive for both hepatitis B surface antigen and the e antigen receive no immunoprophylaxis, 70% to 90% become infected with the virus, and almost all become chronic carriers. Among infants in this study who received hepatitis B immune globulin at birth and three 5- + g doses of yeast-recombinant hepatitis B vaccine, only 4.8% became chronic carriers, a better than 90% level of protection and a rate that is comparable with that seen with immune globulin and plasma-derived hepatitis B vaccine. Hepatitis surface antigen and antibodies were detected by radioimmunoassay. These data suggest that, in this high-risk setting, the yeast-recombinant vaccine is as effective as the plasma-derived vaccine in preventing hepatitis B virus infection and the chronic carrier state

A complex of polyadenylic-polyuridylic acids effectively inhibits the in vivo production of immunologic tolerance to human gamma globulin in mice. Moreover, this effect can be obtained only when the polynucleotide complex is given within 4 hr after antigen administration. Reconstitution of irradiated mice with combinations of T and B cells originating from tolerant or previously untreated mice demonstrates that poly A:U is responsible for the adjuvant effect observed. Poly A:U exerts its adjuvant effect primarily upon T cells, while B cells remain essentially uninfluenced by the polynucleotides

This investigation aimed to study the effects of aflatoxins B 1 +G 1 mixture mainly on total body water (TBW) and on total body solids (TBS) of male albino rats. Some blood components and some reproductive characteristic were also taken into consideration. Two groups, each of 8 male rats were fed the same ration. Rats of one group had been individually ingested daily with a dose of 22 μg B 1 plus 22 μg G 1 for 15 successive weeks. The obtained results showed that aflatoxin administration caused: 1- A decrease in final body weight (FBW), TBW (P<0.01) and TBS (P<0.05). 2- A decrease in serum total proteins (P<0.01), albumin (P<0.05), globulin (P<0.05), glucose (P<0.05) and increase in serum cholesterol, GOT and GPT (P<0.05) activities. 3- A decrease in each of the number of effective matings of males and delivery percentages of females mated with treated males.1 tab

B.Sc in Environmental Hygiene, Kerman University of Medical Sciences Abstract Background: The prevalence rate of opioids consumption is high in Iran. The latest research approach related to substance abuse considers the role of plasma proteins in novel treatments of addiction. Since long-term consumption of opioids has some effects on liver function and plasma transfer systems, the present study was designed to determine the electrophoretic profile of plasma proteins in opiates-addict subjects. Materials and methods: In this cross-control study, the sample groups consisted of 42 opium consumers and 35 heroine dependents as case group and 35 non-addict volunteers as control group. The control group was matched with addicts for age and sex. Opioid consumption was confirmed by laboratory diagnostic tests on urine samples such as immunochromatography (RSA, rapidosis and complementary tests including liquid-solid column chromatography and thin layer chromatography (TLC. After blood collection and serum preparation, serum electrophoresis was performed. Data were presented as mean±SEM and analyzed by SPSS ver.11.5. The comparison of groups was done by using parametric tests and p<0.01 was considered as statistically significant. Results: There was no significant difference in the amounts of albumin, alpha-1-globulin, alpha-2-globulin and beta-globulin between groups. Gamma-globulin concentration was not significantly different between

Background: Wound healing disorders are probably the most common post-transplantation surgical complications. It is thought that wound healing disturbance occurs due to antiproliferative effects of immunosuppressive drugs. On the other hand, success of transplantation is dependent on immunosuppressive therapies. Antihuman thymocyte globulin (ATG) has been widely used as induction therapy but the impact of this treatment on wound healing is not fully understood. Objective: To investigate wound...

Total energy consumption in Finland increased by one percent

The total energy consumption in Finland increased by less than a percent in 1999. The total energy consumption in 1999 was 1310 PJ corresponding to about 31 million toe. The electric power consumption increased moderately by 1.6%, which is less than the growth of the gross national product (3.5%). The final consumption of energy grew even less, only by 0.5%. Import of electric power increased by 19% in 1999. The import of electric power was due to the availability of low-priced electric power on the Nordic electricity markets. Nuclear power generation increased by 5% and the consumption of wood-based fuels by 3%. The increment of the nuclear power generation increased because of the increased output capacity and good operability of the power plants. Wind power production doubles, but the share of it in the total energy consumption is only about 0.01%. The peat consumption decreased by 12% and the consumption of hydroelectric power by 15%. The decrease in production of hydroelectric power was compensated by an increase import of electric power. The consumption of fossil fuels, coal, oil and natural gas remained nearly the same as in 1998. The gasoline consumption, however, decreased, but the consumption of diesel oil increased due to the increased road transport. The share of the fossil fuels was nearly half of the total energy consumption. The consumption of renewable energy sources remained nearly the same, in 23% if the share of peat is excluded, and in 30% if the share of peat is included. Wood-based fuels are the most significant type of renewable fuels. The share of them in 1999 was over 80% of the total usage of the renewable energy sources. The carbon dioxide emissions in Finland decreased in 1999 by 1.0 million tons. The total carbon dioxide emissions were 56 million tons. The decrease was mainly due to the decrease of the peat consumption. The final consumption of energy increased by 0.5%, being hence about 1019 PJ. Industry is the main consumer of energy

We describe our experiences with, and compare the outcomes of, 2 groups of renal transplant patients treated with thymoglobulin or antithymocyte globulin-Fresenius as induction therapy at transplant to reduce the incidence of acute rejection and prevent delayed allograft function. Twenty-four recipients of deceased-donor or living-donor kidney transplants received thymoglobulin, and 23 patients received antithymocyte globulin-Fresenius. Patient and graft survival and efficacy and safety were assessed at 3 months. The demographic characteristics of both groups were comparable, but the predominant donor type was significantly different. Incidence of complications, delayed graft function, and creatinine concentrations were comparable in both groups. At 3 months after the transplant, patient survival rate was 92% in the thymoglobulin group and 96% in the antithymocyte globulin-Fresenius group (P > .05), and death-censored graft survival rate for both groups was not significantly different. Average hematocrit and lymphocyte, neutrophil, and platelet counts were comparable in both groups at 3 months' follow-up. Average white blood count at 1 month was significantly different between the groups: at 5.62 ± 2.45 × 103 cells/mm³ in the thymoglobulin group and 7.85 ± 4.10 × 103 cells/mm³ in the ATG-F group (P Fresenius were generally comparable.

Group-specific component (Gc)-globulin-derived macrophage-activating factor (GcMAF) generated by a cascade of catalytic reactions with deglycosidase enzymes exerts antitumor activity. We hypothesized that degalactosyl Gc-globulin (DG3), a precursor of GcMAF, also plays a role in recovery from cancer as well as GcMAF due to progression of deglycosylation by generally resident sialidases and mannosidases. We prepared the subtypes of DG3, such as 1f1f and 1s1s and its 22 homodimers, by using vitamin D3-binding Sepharose CL-6B and examined their antitumor activity in mice bearing Lewis lung carcinoma cells, by counting the number of nodules formed in their lungs. Antitumor activity of DG3 was observed regardless of its subtype, being equivalent to that of GcMAF. The injection route of DG3 affected its antitumor activity, with subcutaneous and intramuscular administration being more favorable than the intraperitoneal or intravenous route. In order to obtain significant antitumor activity, more than 160 ng/kg of DG3 were required. DG3 proved to be promising as an antitumor agent, similarly to GcMAF.

Full Text Available Abstract Background The 11S globulin Sin a 2 is a marker to predict severity of symptoms in mustard allergic patients. The potential implication of Sin a 2 in cross-reactivity with tree nuts and peanut has not been investigated so far. In this work, we studied at the IgG and IgE level the involvement of the 11S globulin Sin a 2 in cross-reactivity among mustard, tree nuts and peanut. Methods Eleven well-characterized mustard-allergic patients sensitized to Sin a 2 were included in the study. A specific anti-Sin a 2 serum was obtained in rabbit. Skin prick tests (SPT, enzyme-linked immunosorbent assay (ELISA, immunoblotting and IgG or IgE-inhibition immunoblotting experiments using purified Sin a 2, Sin a 1, Sin a 3, mustard, almond, hazelnut, pistachio, walnut or peanut extracts were performed. Results The rabbit anti-Sin a 2 serum showed high affinity and specificity to Sin a 2, which allowed us to demonstrate that Sin a 2 shares IgG epitopes with allergenic 11S globulins from tree nuts (almond, hazelnut, pistachio and walnut but not from peanut. All the patients included in the study had positive skin prick test to tree nuts and/or peanut and we subdivided them into two different groups according to their clinical symptoms after ingestion of such allergenic sources. We showed that 11S globulins contain conserved IgE epitopes involved in cross-reactivity among mustard, tree nuts and peanut as well as species-specific IgE epitopes. Conclusions The allergenic 11S globulin Sin a 2 from mustard is involved in cross-reactivity at the IgE level with tree nuts and peanut. Although the clinical relevance of the cross-reactive IgE epitopes present in 11S globulins needs to be investigated in further detail, our results contribute to improve the diagnosis and management of mustard allergic patients sensitized to Sin a 2.

Methods: Retrospective analysis of 26 pediatric patients with aplastic anemia, treated between 1996 and 2011 with rabbit antithymocyte globulin plus cyclosporine. Results: The overall response rate at six months was 34.6% (9/26, and the cumulative incidence of relapse was 26.5% (95% confidence interval [CI]: 1.4%-66% at 5 years. The cumulative incidence of clonal evolution after immunosuppressive therapy was 8.3% (95% CI: 0.001%-53.7% at five years with both clonal evolutions in non -responders who acquired monosomy 7 karyotype. The overall survival at five years was 73.6% (95% CI: 49.2%-87.5%. Conclusions: The present results confirm the poor response rate with rabbit antithymocyte globulin as first therapy in pediatrics patients, similar to what has been reported for patients of all ages. This confirmation is problematic in Brazil, given the lack of horse antithymocyte globulin in many markets outside the United States.

Sex hormone-binding globulin (SHBG) is a glycoprotein which regulates bioavailability of sex steroid hormones. Interest in SHBG has escalated in recent years because of its inverse association with polycystic ovary syndrome (PCOS), obesity, insulin resistance, metabolic syndrome, and diabetes type II. This meta-analysis was performed to examine the associations of SHBG with PCOS and to correlate serum SHBG levels with various PCOS associated endocrine and metabolic dysregulation as well as to determine the effects of various therapeutic agents on serum SHBG levels in PCOS patients in order to assess the true accuracy of SHBG in the prediction of PCOS. A literature search was performed using Pub-Med, Science direct, google scholar, EMBASE, and Cochrane library. A total of 675 relevant records were identified, of which 62 articles were included. Meta-analysis using a random-effects model was performed using STATA version 13 to calculate standardized mean difference (SMD) with 95% confidence intervals (95 % CIs). SHBG levels in controls were significantly higher than that of PCOS patients (SMD= -0.83, 95%CI = -1.01, -0.64), with significant heterogeneity across studies (I 2 = 93.9% and p=0.000). Our results suggest that the lower serum SHBG levels are associated with the risk of PCOS. SHBG may also play an important role in various metabolic disturbances in PCOS patients. Therapeutic interventions improved SHBG levels in PCOS women which further reduced PCOS associated complications. Therefore, SHBG levels may prove to be a useful biomarker for the diagnosis and treatment of PCOS.

To evaluate the diagnostic value of the ratio of serum thyroxine(T 4 ) /thyroxine-binding globulin (TBG) for the thyroid status in pregnancy and newborn serum thyroxine, TBG, triiodothyronine, and free thyroxine levels were radioimmunoassayed in normal pregnant women at each of the trimesters, and the calculated serum T 4 /TBG ratios were compared with other parameters such as T 3 /TBG ratio and free T 4 /TBG ratio and free T 4 /TBG ratio. Serum T 4 levels were elevated with the proportionate increase in TBG levels during pregnancy, leading to the nearly constant value of serum T 4 /TBG ratios as in normal non-pregnant controls. In contrast, serum T 3 /TBG and free T 4 /TBG ratios varied considerably during pregnancy. In newborn, T 4 levels were nearly not changed with compared non-pregnant control value and TBG levels were elevated. The results indicate that serum T 4 /TBG ratio is a better parameter than others in evaluating the thyroid status during pregnancy and but newborn is a no better.

1986-01-01

Two molecular varieties of thyroxine-binding globulin (TBG) of human retroplacental blood, obtained as a result of fractionation of pure TBG on concanavalin A-Sepharose, were studied. It was shown that these varieties (TBG-1 and TBG-2) are immunologically identical; they have the same molecular weight and amino acid composition, exhibit the same affinity for thyroid hormones, and are indistinguishable in spectral characteristics. And yet, TBG-1 and TBG-2 have differences in charge, detectable in isoelectrofocusing, and a different monosaccharide composition. The existence of molecular varieties of TBG during pregnancy is apparently due to the peculiarities of the glycosylation of the polypeptide chain during TBG biosynthesis

To investigate the clinical characteristics of twins with thyroxine binding globulin (TBG) deficiency and to find SERPINA7 gene mutations. Data(2015) related to clinical characteristics, serum biochemistry, gene mutations and pedigree of two children with TBG deficiency were collected in the First Affiliated Hospital of College of Medicine, Zhejiang University. The related literature was searched form China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, National Center for Biotechnology Information and PubMed (up to December 2015) by using search terms "Thyroxine binding globulin deficiency, gene, mutation" . Both patients were diagnosed as central hypothyroidism at the beginning and treated with L-thyroxine. Both of the identical twins of the triplet were observed for mutation in exon3, c. 631G﹥A(p.A211T), a new mutation had not been reported, but their parents and another non-identical triplet brother were normal. Literature review showed that 23 foreign cases with SERPINA7 gene mutation had been reported, however, no Chinese with SERPINA7 gene mutation had been reported. Among reported cases it was shown that SERPINA7 gene mutations located in exon, intron, promoter and enhancer. Up to now, 49 variants had been identified, 41 of them located in the mutated genes. Including these two cases, patients with thyroxine binding globulin deficiency were characterized by reduced serum TH levels, but normal free TH and TSH and absence of clinical manifestations. The new mutation of SERPINA7 gene c. 631G﹥A(p.A211T)is not transmitted via the known X chromosome linked heredity, and as the cases were test tube triplet infants, it is a de novo mutation. The serum thyroid function tests of TBG deficiency showed decreased TT4, TT3 and normal TSH and TBG deficiency is often misdiagnosed as central hypothyroidism.

2012-12-01

Low albumin to globulin ratio has been found previously to have a high positive predictive value for feline infectious peritonitis (FIP) in cats with clinical signs highly suggestive of the disease. However, FIP can have a more vague clinical presentation. This retrospective study found that the positive predictive value of an albumin:globulin (A:G) ratio of <0.8 and <0.6 was only 12.5% and 25%, respectively, in a group of 100 cats with one or more clinical signs consistent with FIP. The negative predictive value was 100% and 99% for an A:G ratio of <0.8 and A:G<0.6%, respectively. Therefore, when the prevalence of FIP is low, the A:G ratio is useful to rule out FIP but is not helpful in making a positive diagnosis of FIP.

Ganciclovir-resistant cytomegalovirus (CMV) is associated with significant morbidity in solid organ transplant recipients. Management of ganciclovir-resistant CMV may be complicated by nephrotoxicity which is commonly observed with recommended therapies and/or rejection induced by "indirect" viral effects or reduction of immunosuppression. Herein, we report a series of four high serologic risk (donor CMV positive/recipient CMV negative) kidney transplant patients diagnosed with ganciclovir-resistant CMV disease. All patients initially developed "breakthrough" viremia while still receiving valganciclovir prophylaxis after transplant and were later confirmed to exhibit UL97 mutations after failing to eradicate virus on adequate dosages of valganciclovir. The patients were subsequently and successfully treated with reduced-dose (1-2 mg/kg) cidofovir and CMV-hyperimmune globulin, given in 2-week intervals. In addition, all patients exhibited stable renal function after completion of therapy, and none experienced acute rejection. The combination of reduced-dose cidofovir and CMV-hyperimmune globulin appeared to be a safe and effective regimen in patients with mild disease due to ganciclovir-resistant CMV.

Volume and globulin increased significantly where where as body weight, albumin and albumin/globulin ratio decreased significantly. These differences in the physiological and biochemical parameters in disease induced condition require the necessity for analyzing this condition for the changes in the pharmacokinetics parameter like, absorption distribution metabolism and excretion leading to alteration in the pharmacokinetics of drug.

Full Text Available Compounds isolated from Agaricus blazei Murill represent a group of promising natural immunomodulators for use in the treatment of neoplasms. We have evaluated the serum biochemical profile of healthy and Ehrlich tumor-bearing mice treated with different extracts of A. blazei. Total, supernatant, and polysaccharide extracts of A. blazei were obtained from suspensions (at acidic or neutral pH kept in a water bath at 60 °C or in an ultrasonic bath at 37 °C. After oral administering the extracts to mice for 21 days, blood samples were collected for determination of aspartate aminotransferase (AST, alanine aminotransferase (ALT, creatine kinase (CK, urea, total protein, albumin, globulins, and alpha-, beta- and gamma-globulin fractions. The presence of the tumor led to a significant increase in serum CK and AST activities and in the concentrations of total globulin and the gamma-globulin fraction, and to a decrease in the albumin and alpha2-globulin levels. The polysaccharide extracts of A. blazei reduced the serum AST and ALT activities, probably due to a hepatoprotective effect. In addition, polysaccharide and supernatant extracts inhibited the tumor-induced increase in gamma-globulin levels. Thus, the supernatant and polysaccharide fractions of the extract of A. blazei have potential for use in complementary antineoplastic treatments.

James, Andrew T; Yang, Aijun

2016-03-01

The content and globulin subunit composition of soybean proteins are known to affect tofu quality and food-grade soybeans usually have higher levels of proteins. We studied the tofu quality of soybeans with high (44.8%) or low (39.1%) protein content and with or without the 11S globulin polypeptide, 11SA4. Both protein content and 11SA4 significantly affected tofu gel properties. Soybeans containing more protein had smaller seeds which produced significantly firmer (0.663 vs.0.557 N, pseed size, tofu hardness and water holding capacity and led to significant changes to the profile of storage protein subunits, which may have contributed to the improvement in tofu gel properties. These results suggest that, in combination with higher protein content, certain protein subunits or their polypeptides can also be targeted in selecting soybeans to further improve soy food quality.

Male F-344 rats were administered corn oil (vehicle control), d-limonene (positive control, 300 mg/kg), or MIBK (1000 mg/kg) and female F-344 rats corn oil (vehicle control) or MIBK for 10 consecutive days by oral gavage. Approximately 24 h after the final dose the kidneys were excised and the left kidney prepared and evaluated for histological changes including protein (hyaline) droplet accumulation, immunohistochemical staining for α2u-globulin (α2u), and proliferating cell nuclear antigen (PCNA) to quantitate renal cell proliferation. The right kidney was prepared for quantitation of total protein and α2u using an ELISA. MIBK elicited an increase in protein droplets, accumulation of α2u, and renal cell proliferation in male, but not female rats, responses characteristic of α2u-mediated nephropathy. MIBK produced identical histopathological changes in the male rat kidney when compared to d-limonene, an acknowledged inducer of α2u-nephropathy except that the grade of severity tended to be slightly lower with MIBK. MIBK did not induce any effects in female rats. Therefore, renal histopathology, along with the other measures of α2u accumulation, provides additional weight of evidence to support the inclusion of MIBK in the category of chemicals exerting renal effects through a α2u-nephropathy-mediated mode-of-action

Serum corticosteroid levels are routinely measured as markers of stress in wild animals. However, corticosteroid levels rise rapidly in response to the acute stress of capture and restraint for sampling, limiting its use as an indicator of chronic stress. We hypothesized that serum corticosteroid binding globulin (CBG), the primary transport protein for corticosteroids in circulation, may be a better marker of the stress status prior to capture in grizzly bears (Ursus arctos). To test this, a full-length CBG cDNA was cloned and sequenced from grizzly bear testis and polyclonal antibodies were generated for detection of this protein in bear sera. The deduced nucleotide and protein sequences were 1218 bp and 405 amino acids, respectively. Multiple sequence alignments showed that grizzly bear CBG (gbCBG) was 90% and 83% identical to the dog CBG nucleotide and amino acid sequences, respectively. The affinity purified rabbit gbCBG antiserum detected grizzly bear but not human CBG. There were no sex differences in serum total cortisol concentration, while CBG expression was significantly higher in adult females compared to males. Serum cortisol levels were significantly higher in bears captured by leg-hold snare compared to those captured by remote drug delivery from helicopter. However, serum CBG expression between these two groups did not differ significantly. Overall, serum CBG levels may be a better marker of chronic stress, especially because this protein is not modulated by the stress of capture and restraint in grizzly bears.

Our study was designed to assess whether AGR is associated with the prognosis of gastric cancer patients. Patients and methods: A total of 507 gastric cancer patients between 2005 and 2012 were included. The AGR was defined as the ratio of serum albumin to nonalbumin and calculated by the equation: albumin/(total protein - albumin. Furthermore, AGR was divided into two groups (low and high using the X-tile software. Survival analysis stratified by AGR groups was performed. Results: The mean survival time for each group was 36.62 months (95% CI: 33.92–39.32 for the low AGR group and 48.95 months (95% CI: 41.93–55.96, P=0.003 for the high AGR group. Patients in the high group (AGR ≥1.93 had a significantly lower 5-year mortality in comparison with the low group (AGR <1.93 (52.4% vs 78.5%, P=0.003. The high AGR group showed obviously better overall survival than the low AGR group according to Kaplan–Meier curves (P=0.003. Multivariate analysis showed that AGR was an independent predictive factor of prognosis in gastric patients. Conclusion: Pretreatment AGR is a significant and independent predictive factor of prognosis. Keywords: gastric cancer, survival, inflammation, albumin–globulin ratio

Radiation modification of protein based polymers as well as the development of gamma irradiation techniques as a method of food sterilisation and preservation induces necessity of better recognition of the physicochemical changes occurring in proteins after gamma irradiation. Recently differential scanning calorimetry (DSC) was applied widely in structural studies of proteins. Also thermoanalytical methods (TG, DTG) applied for proteins pyrolysis were also found to be useful in characterisation of proteins structure and the properties of proteins containing tissues. In presented paper, the aforementioned methods were applied for investigation of the gamma irradiation influence on thermal decomposition of gamma and alpha globulins and the results were related to their structural modifications. It has been found, that irradiation influences the course of decomposition of gamma and alpha globulins. Irradiation of solid native proteins result in decreased temperature of decomposition, especially decreased temperature of the last stage. The effects of irradiation performed for water suspensions were clearly more significant. The relatively large differences between decomposition of the irradiated and non-irradiated samples were detected by DSC and thermogravimetry already after irradiation of water suspensions

A comparative study was made of the serological properties and virus-neutralizing activity of antiencephalitis gamma-globulin and Fab-fragments isolated from it by gel-filtration. Horse immunoglobulins against the autumno-summer tick-borne encephalitis virus could be disintegrated with the aid of papaine to monovalent Fab-fragments which (according to the complement fixation reaction, the test of suppression of the complement fixation, and the HAIT) retained the serological activity whose level was compared with that of the serological activity of gamma-globulin. Fab-fragments possessed a marked virus-neutralizing activity. The mean value of a logarithm of the neutralization index was 2.65 +/- 0.2 for Fab-fragments and 3.74 +/- 0.38 for gamma-globulin (P less than 0.01).

Objectives The aim of this study was to evaluate whether the frequency of electrophoretic changes in serum of cats with feline infectious peritonitis (FIP) changed in recent years vs past years. Methods Agarose gel electrophoresis (AGE) and capillary zone electrophoresis (CZE) from cats with FIP and healthy cats recorded in the periods 2004-2009 and 2013-2014 were retrospectively analysed. Relative and absolute values of each electrophoretic fraction were recorded and the number of cats showing single or combined electrophoretic changes consistent with FIP (hypoalbuminaemia, inverted albumin to globulin [A:G] ratio, increased total protein, total globulin, alpha [α] 2 -globulin and gamma [γ]-globulin concentration) were counted. Additionally, a visual analysis of electrophoretograms was also performed. Results for the two time periods were statistically compared. Results The details of 91 AGE procedures (41 from cats with FIP and 50 from healthy cats) and 45 CZE procedures (26 from cats with FIP and 19 from healthy cats) were obtained from the database. No significant differences between the two time periods were found both in FIP and in healthy cats analysed with CZE and in healthy cats analysed with AGE. Compared with 2004-2009, cats with FIP sampled in 2013-2014 with AGE showed a significantly lower concentration of total protein, γ-globulins and total globulins, and a significantly higher A:G ratio and percentage of albumin and α 2 -globulins. Using both AGE and CZE, in recent years the proportion of cats with high α2-globulins without gammopathy and the proportion of cats with gammopathy alone decreased. With a visual approach, the number of patterns considered as dubious increased in the second period with AGE (non-statistically significant). Conclusions and relevance The frequency of electrophoretic abnormalities in cats with FIP decreased in recent years, independently of the technique employed. Although the mechanism responsible for this change was

Elevation of corticosteroid-binding globulin in Obese strain (OS) chickens: possible implications for the disturbed immunoregulation and the development of spontaneous autoimmune thyroiditis

Faessler, R.; Schauenstein, K.; Kroemer, G.; Schwarz, S.; Wick, G.

1986-01-01

Basal plasma levels of corticosterone and corticosteroid-binding globulin (CBG) have been investigated in Obese strain (OS) chickens afflicted with spontaneous autoimmune thyroiditis (SAT). Corticosterone was determined radioimmunologically, and CBG by using a highly sensitive radioligand saturation assay. OS chickens displayed total corticosterone levels not different from healthy normal White Leghorn (NWL) chickens. CBG, however, was found to be twice as high in OS chickens as compared with their healthy counterparts, irrespective of sex or age. This quantitative difference in the CBG level is not compensated for by either altered affinity or specificity of the molecule. Furthermore, no differences were found in the response of OS and NWL lymphocytes to the suppressive effect of glucocorticoids in vitro. It was therefore assumed that OS animals are deficient in free, hormonally active corticosterone. An additional indication for such a diminished glucocorticoid tonus was that in vivo treatment of OS chickens with glucocorticoid hormones, thus increasing the free and active hormone fraction, normalizes the T cell hyperreactivity and significantly reduces thyroid infiltration. Possible pathophysiological implications of a diminished glucocorticoid tonus for spontaneous autoimmunity, as well as possible explanations for the beneficial effects of glucocorticoid treatment on the development of SAT, are discussed

Background: Androgens are involved in the development of acne. The aim of this study was to find out if there was an association of serum testosterone and sex hormone binding globulin (SHBG) in females with acne based on its severity. Methods: It was a cross sectional study, conducted in Dermatology unit of Fauji Foundation Hospital (FFH), Rawalpindi. Duration of study was eight months. Adult females with acne were enrolled in the study. Patients were categorized into minor, mild, moderate groups. Blood samples were taken for serum testosterone and SHBG. Results: Five hundred and thirty-one adult female were enrolled into the study. The mean age was 21.49±4.73 years. Acne was graded as minor in 78 (14.7 percent) cases, mild in 248 (46.7 percent) and moderate in 205 (38.6 percent). There was no statistically significant relationship between the levels of serum testosterone (p=0.776) and SHBG (p=0.711) with acne severity. Conclusion: There was no association of serum testosterone and sex hormone binding globulin levels in females with acne based on its severity. (author)

Increasing productivity through Total Reuse Management (TRM)

Science.gov (United States)

Schuler, M. P.

1991-01-01

Total Reuse Management (TRM) is a new concept currently being promoted by the NASA Langley Software Engineering and Ada Lab (SEAL). It uses concepts similar to those promoted in Total Quality Management (TQM). Both technical and management personnel are continually encouraged to think in terms of reuse. Reuse is not something that is aimed for after a product is completed, but rather it is built into the product from inception through development. Lowering software development costs, reducing risk, and increasing code reliability are the more prominent goals of TRM. Procedures and methods used to adopt and apply TRM are described. Reuse is frequently thought of as only being applicable to code. However, reuse can apply to all products and all phases of the software life cycle. These products include management and quality assurance plans, designs, and testing procedures. Specific examples of successfully reused products are given and future goals are discussed.

Steroid hormone-binding globulin in human serum displays different isoelectric focusing (IEF) patterns among individuals, suggesting genetic variation in the gene for this extracellular steroid carrier protein. Analysis of allele frequencies and family studies suggested the existence of two codominant alleles of the gene. Subsequent determination of the molecular basis of a variant of the gene was carried out using DNA from homozygous individuals from a single Belgian family. It was of interest to characterize other variant individuals to determine whether all variants identified by IEF phenotyping were caused by the same mutation or whether other mutations occurred in the gene in different populations. Previous studies identified Mexican subjects who were heterozygous for the variant IEF phenotype. Denaturing gradient gel electrophoresis was used to localize the mutation in these subjects and to purify the variant allele for DNA sequence analysis. The results show that the mutation in this population is identical to that identified in the Belgian family, and no other mutations were detected in the gene. These data represent the first analysis of steroid hormone-binding globulin gene variation in heterozygous subjects and further support the conclusion of biallelism of the gene worldwide. 11 refs., 2 figs., 1 tab.

A possible relationship between melatonin (MEL) secretion and pituitary-testicular function as well as the circadian rhythmicity of serum MEL, lutropin (LH), folitropin (FSH), estradiol (E 2 ), total testosterone (T) and sex hormone-binding globulin (SHBG) were evaluated in 16 men with the primary obesity (body mass index - BMI > 43 kg/m 2 ; waist-to-hip circumference ratio - WHR > 1.0) and in 17 healthy volunteers with normal body weight. The mean 24-h MEL level was significantly higher in obese patients than in healthy control individuals. Moreover, all obese men showed some abnormalities of MEL circadian pattern such as decreased ratio between day and night MEL levels, abnormal secretory peaks during the light hours and lower interindividual variability for timing amplitude. Abnormal circadian variations of MEL were associated with reduced 24-h mean values of LH, FSH, T and SHBG, whereas E 2 levels were elevated. (author). 49 refs, 4 figs, 2 tabs

The incidence of graft rejection was determined in 66 children with acquired aplastic anaemia (AA) following bone marrow transplantation (BMT) from a related donor. Eleven of 65 evaluable patients experienced either early or late rejection. Multivariate analysis identified previous immunosuppressive therapy with antithymocyte-globulin (ATG) and ciclosporin (CsA) as a risk factor for graft rejection (relative risk: 16.6, P = 0.001). Patients who received ATG and CsA had a significantly lower probability of failure-free survival than those who did not (69.7 +/- 6.2% vs. 87.9 +/- 8.0%, P = 0.044). These results suggest that BMT should be instituted immediately in children with severe AA who have human leucocyte antigen-identical siblings.

Broad T cell depletion by polyclonal anti-thymocyte globulins (ATG) has been used for many years as a part of immunosuppressive treatment in transplantation. Currently, two different ATG are used in clinical practice, Thymoglobulin and Grafalon. Due to differences in the immunization source, these products contain different specificities and quantity of antibodies. These differences may have clinical consequences. We conducted a nested study in a large prospective multicentric cohort of kidney transplant to determine whether Grafalon-treated and Thymoglobulin-treated patients experience different lymphocyte reconstitution and clinical outcomes. 182 patients matched for age, gender, CMV status, CMV prophylaxis, number of previous transplantation, and maintenance immunosuppressive treatment were included (Thymoglobulin, [n=91]; Grafalon®, [n=91]). One-year post-transplant, recent thymic emigrants were significantly decreased (12±10% vs 21±12%; p<0.001) in Grafalon-treated patients. By contrast, T cell activation (CD38+DR+Ki67+) and senescence (CD8+CD57+CD28-) was increased in Thymoglobulin-treated patients. Compared to Grafalon, Thymoglobulin was not associated with a significantly different rate of acute rejection. CMV disease (p=0.013) was more frequent in Thymoglobulin-treated patients. Grafalon and Thymoglobulin seem to be equivalent to prevent acute rejection. CMV disease is more frequent in Thymoglobulin-treated patients. One year post-transplant immune profile profoundly differs according to the type of ATG. Copyright © 2017 Elsevier B.V. All rights reserved.

Acute Lung Injury during Antithymocyte Globulin Therapy for Aplastic Anemia

Directory of Open Access Journals (Sweden)

Ewan Christopher Goligher

2009-01-01

Full Text Available The case of a 33-year-old man with aplastic anemia who experienced recurrent episodes of hypoxemia and pulmonary infiltrates during infusions of antithymocyte globulin (ATG is described. With the use of high-dose corticosteroids, the patient’s original episodes resolved, and were subsequently prevented before additional administrations of ATG. Rare reports of an association between ATG and acute lung injury are found in the literature, but this is the first report of successful steroid-supported re-exposure. Although the mechanism of ATG-related acute lung injury remains uncertain, it may be parallel to the mechanism of transfusion-related acute lung injury because the pathogenesis of the latter relies, in part, on antileukocyte antibodies. ATG-related toxicity should be included in the differential diagnosis of new, infusion-associated pulmonary infiltrates, and corticosteroids may be a useful therapeutic consideration in the management.

Associations of smoking habit with serum levels of total protein as well as protein fractions were studied in a population consisting of 4,739 atomic-bomb survivors and unexposed control subjects in Hiroshima, Japan who participated in the 1979-1981 period of the Adult Health Study, an ongoing health follow-up program of the Radiation Effects Research Foundation. Smoking was strongly related to serum protein concentration after correction for age, sex, and body mass index. Among current smokers, levels of total protein, beta globulin, and gamma globulin were significantly lower and levels of alpha-1 and alpha-2 globulin were significantly higher, when compared with nonsmokers. For serum albumin levels a decrease was also noted, but it failed to attain statistical significance. Ex-smokers were indistinguishable from nonsmokers in terms of the serum protein levels analyzed. With an increase of the amount of daily cigarette consumption, monotonic increases of serum levels were observed only in alpha-1 globulin. Duration of smoking was related to increased alpha-1 and alpha-2 globulin. Smoking duration was also associated with albumin level, but the trend was not monotonic. The radiation exposure effect on serum protein level was significant in several instances but was in general much smaller than the smoking effect, and its inclusion in the regression models did not noticeably affect the association between smoking and serum proteins

Immunosuppressive therapy (IST) with antithymocyte globulin (ATG) and cyclosporine (CsA) is the standard treatment for children with severe aplastic anemia (SAA) with no human leukocyte antigen-matched siblings. Due to the unavailability of horse ATG in China, porcine antilymphocyte globulin (p-ALG), which is less expensive and more effective than rabbit ATG, is widely used. We sought to evaluate the efficacy and safety profile of modified IST with p-ALG plus delayed CsA at day 21 in 50 SAA children. Eighteen SAA patients who progressed from nonsevere aplastic anemia (NSAA) were classified as SAA-II; the other 32 patients were classified as SAA-I. Overall response (OR) rates at 3, 6 and 12 months were 56, 64 and 62%, respectively. The 10-year overall survival (OS) rate and disease-free survival (DFS) rate were 80 and 56%. The OR, OS and DFS rates in the SAA-I group were clearly better than those in the SAA-II group. Death rate from infection within 30 days was 4%. Modified IST with p-ALG plus delayed CsA is a reliable and well-tolerated treatment for children with SAA, and reduces early death due to infection. Modified IST is more suitable for children with SAA-I.

Full Text Available The objective of our study was to determine the effects of clinoptilolite supplemented in colostrum on the blood serum protein electrophoretic pattern of new-born calves. Methods: Romanian Black and White new-born calves involved in the study were divided into 3 groups: the control group (C that received colostrum without clinoptilolite, and experimental groups I (E1 and II (E2 that received colostrum supplemented with 0.5% and 2% clinoptilolite, respectively. The concentration of total protein and protein fractions (albumin, α1-globulin, α2-globulin, β-globulin and γ-globulin were analyzed by electrophoresis on cellulose acetate. Results: At hour 30 after birth, concentrations of γ-globulins, β-globulin and total protein in E1 group of calves were higher than in control group by 42.11% (p < 0.05, 28.48% (p > 0.05 and 18.52% (p > 0.05, respectively, and were higher, but not significantly, in group E2 compared to the control group. This was in accordance with a significant lower albumin/globulin ratio in groups E1 and E2 (29.35%, p < 0.05 and 35.87%, p < 0.05, respectively than in control group at 30 h postpartum, which indicates an obvious increase of the globulins fraction in experimental groups. The conclusion: Clinoptilolite was effective in improving passive transfer in new-born calves, but it was more effective if added in colostrum with a dose of 0.5% than with a dose of 2%.

Imamura, Rikiyo; Yoshimasa, Yasunao; Hamada, Satoshi

1979-01-01

Serum levels of thyroxine (T 4 )-binding globulin (TBG) were determined by a radioimmunoassay using cellulose-linked antibody to TBG. Values obtained in healthy young adults averaged 1.62 +- 0.25 (SD) mg/100 ml, and no significant difference was detected between males and females. The TBG levels remained within the normal limit in hyperthyroidism while they were significantly increased in hypothyroidism. Interestingly enough, TBG levels were significantly elevated in chronic thyroidities with no overt hypothyroidism. In normal pregnancy, TBG was increased slightly in the first trimester, and markedly in the second and third trimesters. In one case of congenital TBG deficiency, no immunoreactive TBG was detected. It was demonstrated, further, that an inverse relationship (r = -0.7593) existed between the TBG level and serum triiodothyronine uptake index, and that a direct relation (r = +0.6557) was present between the TBG level and T 4 in sera from normal subjects and pregnancy. Ratios of T 4 /TBG were markedly increased in hyperthyroidism, and decreased in hypothyroidism, showing no overlap with the normal subjects, whereas they were below the normal limit in half the cases in the second and third trimesters of pregnancy. The radioimmunoassay for TBG was useful in evaluating hypothyroid states, because it could differentiate the increase in T 4 associated with elevated TBG from hyperthyroidism. (author)

To assess the predictive value of the albumin to globulin ratio (AGR) in evaluation of disease severity and prognosis in myasthenia gravis patients. A total of 135 myasthenia gravis (MG) patients were enrolled between February 2009 and March 2015. The AGR was detected on the first day of hospitalization and ranked from lowest to highest, and the patients were divided into three equal tertiles according to the AGR values, which were T1 (AGR 1.53). The Kaplan-Meier curve was used to evaluate the prognostic value of AGR. Cox model analysis was used to evaluate the relevant factors. Multivariate Logistic regression analysis was used to find the predictors of myasthenia crisis during hospitalization. The median length of hospital stay for each tertile was: for the T1 21 days (15-35.5), T2 18 days (14-27.5), and T3 16 days (12-22.5) (Pmyasthenia gravis. At the multivariate Cox regression analysis, the AGR (Pmyasthenia gravis patients. Respectively, the hazard ratio (HR) were 4.655 (95% CI: 2.355-9.202) and 0.596 (95% CI: 0.492-0.723). Multivariate Logistic regression analysis showed the AGR (Pmyasthenia crisis. The AGR may represent a simple, potentially useful predictive biomarker for evaluating the disease severity and prognosis of patients with myasthenia gravis.

The effect of a 60-day period of treatment with L-T/sub 3/ (200 ..mu..g/day) was evaluated in hirsute obese women and normal controls. The obese patients were also submitted to a low calorie high protein diet. Mean initial weight significantly declined with a significant lowering of the mean DHEA-S level. There were changes in serum T/sub 3/ which rose in both obese and normal patients. Serum sex-hormone binding globulin levels at baseline studies were significantly higher in normal controls than in obese patients. At the end of the 60-day period of L-T/sub 3/ administration it was observed in both groups a 2-4 fold increase in serum SHBG levels but normal controls had significantly higher mean values than obese individuals.

The present study was carried out to investigate the role of epinephrine in modifying the radiation induced effects on serum protein as presented by total protein, protein fractions and albumin/globulin (A/G) ratio in adult albino rats. Epinephrine was intraperitoneally injected at a concentration of 200 M/g body weight, 15 min, pre-9 or just after 0 whole body gamma-irradiation of rats at a dose of 6 Gy (single dose). Studies have been undertaken at periods of 1 hr, 4 hrs, 1,3 and 7 days after irradiation. Data of the present study revealed that whole body gamma-irradiation induced significant decreased in the total content of serum protein and albumin at 1,3 and 7 days post radiation exposure alpha 1-globulin significantly increased only on the 1 st hr post-irradiation, however alpha 1-globulin significantly increased along all the experimental periods. B-globulin insignificantly changed after irradiation but gamma-globulin significantly decreased during the experimental periods. These changes were associated with significant decreases in A/G ratio at 3 and 7 days post-irradiation. Administration of epinephrine pre-or after radiation exposure produced some amelioration in the radiation induced changes in the studied parameters. So, it could be concluded that epinephrine plays a beneficial radioprotective role through its pharmacologic properties

To evaluate the efficacy, safety, and costs of rabbit antithymocyte globulin (TMG) induction in patients who received kidney transplants from living unrelated donors. Retrospective cohort study. Large academic medical center. Eighty-seven patients who received kidney transplants from living unrelated donors: 40 of the recipients underwent transplantation between January 1, 2003, and December 31, 2004, and did not receive TMG induction (no induction group); 47 underwent transplantation between January 1, 2005, and June 30, 2006, and received TMG induction (induction group). All patients received cyclosporine-based immunosuppression. Biopsy-proven acute rejection, posttransplantation complications, and inpatient hospital costs for the first 12 months after transplantation were compared between groups using standard univariate statistical analyses. Induction significantly decreased the occurrence of biopsy-proven acute rejection versus no induction (2% vs 48%, pTMG treatment. Slightly elevated initial costs associated with TMG induction were offset by lower costs related to rejection treatment. Total inpatient costs for the 12 months after transplantation were comparable between the groups (no induction $66,038 vs induction $74,183, p>0.05). For the no induction versus induction groups, no significant differences in cytomegalovirus disease (5% vs 6%), malignancy (3% vs 2%), graft failures (5% vs 6%), mortality (5% vs 4%), and serum creatinine concentrations (mean +/- SD 1.4 +/- 0.3 vs 1.5 +/- 0.3 mg/dl) were observed at 12 months (p>0.05 for all comparisons). Five-day TMG induction effectively reduced the 1-year acute rejection rate without significantly increasing total inpatient costs or posttransplantation complications among recipients of kidney transplants from living unrelated donors.

2016-04-01

The influence of heating (100 °C; 0-15 min) on the relative molecular mass, protein unfolding and secondary structure of quinoa globulins was studied at pH 6.5 (low solubility), 8.5 and 10.5 (high solubility). The patterns of denaturation and aggregation varied with pH. Heating triggered the disruption of the disulfide bonds connecting the acidic and basic chains of the chenopodin subunits at pH 8.5 and 10.5, but not at pH 6.5. Large aggregates unable to enter a 4% SDS-PAGE gel were formed at pH 6.5 and 8.5, which became soluble under reducing conditions. Heating at pH 10.5 lead to a rapid dissociation of the native chenopodin and to the disruption of the subunits, but no SDS-insoluble aggregates were formed. No major changes in secondary structure occurred during a 15 min heating, but an increase in hydrophobicity indicated unfolding of the tertiary structure in all samples.

Blood serum proteins are significant indicators of animal health. Nevertheless, several factors should be considered to appropriately interpret their concentrations in blood. Therefore, the objectives of this study were (1) to assess the effect of herd productivity, breed, age and stage of lactation on serum proteins and (2) to investigate association between serum proteins and somatic cell count (SCC) in dairy cattle. Milk and blood samples were collected from 1508 cows of six different breeds (Holstein Friesian, Brown Swiss, Jersey, Simmental, Rendena and Alpine Grey) that were housed in 41 multi-breed herds. Milk samples were analyzed for composition and SCC, while blood samples were analyzed for serum proteins (i.e. total protein, albumin, globulin and albumin-to-globulin ratio (A : G)). Herds were classified as low or high production, according to the cow's average daily milk energy yield adjusted for breed, days in milk (DIM) and parity. Data were analyzed using a linear mixed model that included the fixed effects of DIM, parity, SCS, breed, herd productivity and the random effect of the Herd-test date within productivity level. Cows in high producing herds (characterized also by greater use of concentrates in the diet) had greater serum albumin concentrations. Breed differences were reported for all traits, highlighting a possible genetic mechanism. The specialized breed Jersey and the two dual-purpose local breeds (Alpine Grey and Rendena) had the lowest globulin concentration and greatest A : G. Changes in serum proteins were observed through lactation. Total protein reached the highest concentration during the 4th month of lactation. Blood albumin increased with DIM following a quadratic pattern, while globulin decreased linearly. As a consequence, A : G increased linearly during lactation. Older cows had greater total protein and globulin concentrations, while albumin concentration seemed to be not particularly affected by age. A linear relationship

Isoforms of thyroxine-binding globulin as a model for molecular epidemiology of human cancer risk

International Nuclear Information System (INIS)

Golovaty, A.S.; Lapko, A.G.

2000-01-01

The novel field of molecular epidemiology of human cancer risk has added a new branch to classical epidemiology by providing a direct link between human cancer and carcinogen exposure. It was estimated that about 80% of cancers are due to environmental factors. The blood proteins are almost certainly targets for modification in human cancer, and their identification and characterization will be of primary importance in the development of the new and rapidly evolving field of molecular epidemiology. Among blood proteins that are altered in human cancer, TBG occupies a special place because the level of human blood TBG is the most sensitive to intensification of biosynthesis and proliferation processes in organisms in different types of cancer. The increase of TBG concentration in cancer can be result from both activation of TBG biosynthesis in liver or altering of post translation glycosylation that prolongs protein survival time. The molecular basis for the change in the properties of TBG in cancer is unknown. These distinctive changes could have important consequences for the function of TBG in cancer and may help to develop more precise markers for monitoring pathological progression in this disease. Considerable variability and subtlety can occur in the carbohydrate composition and structure of serum glycoproteins in disease. This can be either as a major change, such as an increase in the number of oligosaccharide branches at a particular glycosylation site or as a minor change such as the addition of an extra fucose or sialic acid residue. Increased fucosylation has also been reported for transferrin and alpha-fetoprotein in liver cancer; thyroglobulin in thyroid cancer, IgG in myeloma, haptoglobin in ovarian cancer. The last own studies have shown that in clinically healthy teenagers born in Khojniki (137 Cs 185-555 kBq/m), we have found an unusual thyroid profile exhibiting increased levels of total triiodothyronine (T3), total thyroxine (T4), and thyroxine

This investigation was undertaken to evaluate thyroxine-binding globulin (TGB) as a marker of liver tumors, in conjection with the liver scintigram. Of 30 patients with primary hepatocellular carcinoma (PHC), 22 (73.3%) showed significantly higher TBG concentrations. Eight patients (26.7%) showed normal TBG concentrations. In the case of 27 our of 30 patients with definite liver tumors, defects were apparent on the scintigrams. But seven of them had normal TBG concentrations in spite of the defects on the scintigrams. Out of 33 postoperative patients with liver metastasis, 28 (84%) had a raised TBG concentration. Only five (15.2%) had a normal TBG level. In 31 patients (93.9%) out of 33 with liver metastasis, a definite diagnosis was made on the basis of the liver scintigram. In 28 (90.3%) of these 31 people, the TBG concentration was higher than normal. Among 63 patients with liver tumors, both primary and metastatic, the test sensitivity for liver tumors was 92.1% (58/63) based on the accuracy of the liver scintigram. It was 79.4% (50/63) based on the TBG measurement. Why TBG increases to such an extent in spite of the euthyroid state remains unexplained. But it may be concluded that elevated TBG with positive liver scintigram furnishes a sensitive, fairly reliable, nonspecific tumor marker to determine liver tumors, especially in the case of liver metastasis.

The amount of tracer [125I]T4 bound to serum thyronine-binding globulin (TBG) was measured by polyacrylamide gel electrophoresis in adult thyroidectomized (TX) rats and normal 1-day to 4-week-old rat puts. Thyroidectomy was associated with the appearance of significant amounts of [125I]T4 binding to serum TBG in lean rats, but not in obese Zucker rats. Treatment of the TX rats in vivo with replacement doses of T4 prevented this increase in TBG binding, but enrichment of serum from TX rats with T4 did not. Significant amounts of tracer [125I]T4 binding to TBG was present in serum from 1- to 3-week-old normal rat pups, but not in 1-day- or 4-week-old pups. There were significantly higher levels of TBG binding of [125I]T4 in serum from 2-week-old rat pups raised in litters of 16 pups compared to those raised in litters of 4 pups. All manipulations that result in the appearance of TBG in rat serum also result in either weight loss or a slowing in the rate of growth, suggesting that the appearance of TBG in rat serum has a nutritional component. This possibility is further supported by the observations that increases in TBG binding of [125I]T4 are not found in obese Zucker rats fed a low protein-high carbohydrate diet for 14 days or fasted for 7 days, or after thyroidectomy, perhaps owing to the large stores of fuel in the obese rat

In a clinical setting, especially with species of special interest, it is important to use all clinical pathology testing options for general health monitoring and diagnosis. Protein electrophoresis (EPH) has previously been shown to be an important adjunct tool in veterinary medicine. Serum samples from 18 free-ranging and 12 zoo-based koalas (Phascolarctos cinereus) were subject to EPH analysis. Significant differences were found between the two groups for the following values: total protein, albumin, beta globulins, and albumin-globulin ratio (P < 0.05). By using the combined data, the minimum-maximum values for the EPH fractions were as follows: total protein 5.0-7.8 g/dl, albumin 2.8-4.7 g/dl, alpha-1 globulins 0.5-1.1 g/dl, alpha-2 globulins 0.3-0.7 g/dl, beta globulins 0.4-1.0 g/dl, gamma globulins 0.2-1.0 g/dl, and albumin-globulin ratio 1.0-2.1.

Serum protein concentrations provide insight into the nutritional and immune status of organisms. It has been suggested that some marine turtles are capital breeders that fast during the nesting season. In this study, we documented serum proteins in neophyte and remigrant nesting leatherback sea turtles (Dermochelys coriacea). This allowed us to establish trends across the nesting season to determine whether these physiological parameters indicate if leatherbacks forage or fast while on nesting grounds. Using the biuret method and agarose gel electrophoresis, total serum protein (median = 5.0 g/dl) and protein fractions were quantified and include pre-albumin (median = 0.0 g/dl), albumin (median = 1.81 g/dl), α1-globulin (median = 0.90 g/dl), α2-globulin (median = 0.74 g/dl), total α-globulin (median = 1.64 g/dl), β-globulin (median = 0.56 g/dl), γ-globulin (median = 0.81 g/dl) and total globulin (median = 3.12 g/dl). The albumin:globulin ratio (median = 0.59) was also calculated. Confidence intervals (90%) were used to establish reference intervals. Total protein, albumin and total globulin concentrations declined in successive nesting events. Protein fractions declined at less significant rates or remained relatively constant during the nesting season. Here, we show that leatherbacks are most likely fasting during the nesting season. A minimal threshold of total serum protein concentrations of around 3.5–4.5 g/dl may physiologically signal the end of the season's nesting for individual leatherbacks. The results presented here lend further insight into the interaction between reproduction, fasting and energy reserves and will potentially improve the conservation and management of this imperiled species.

Full Text Available Studies of the changes in serum protein pattern in the neonatal period in animals are still limited. Therefore, the objective of this study was to evaluate the changes in the concentrations of serum protein fractions in 7 clinically healthy merino lambs (4 males, 3 females during their first month of life. The first blood sampling was performed before the colostrum intake and then at 1, 2, 7, 14 and 30 days of age. Blood serum was analysed for total serum protein concentrations and for the relative and absolute values of serum protein fractions - albumin, alpha1- (α1, alpha2- (α2, beta- (β, and gamma- (γ globulins. The results showed a significant effect of age on the serum total protein concentrations and for all the protein fractions. The concentrations of total proteins and γ-globulins increased significantly 1 day after the colostrum intake (P P 1-globulins significantly decreased during the first month of life (P 2- and β-globulins increased significantly from birth till the end of the monitored period (P < 0.001. Our results suggest that the serum protein electrophoretic pattern in growing lambs is significantly influenced by the age of the evaluated animal, and this should be taken into consideration when interpreting the serum protein profile. Our findings extend existing knowledge about significant changes in the protein profile associated with the physiological adaptation process in the neonatal period in young animals.

Full Text Available Over 2003-2005 at the Experiment Station at Wierzchucinek at the University of Technology and Life Sciences in Bydgoszcz, there was performed a strict one-factor micro-plot experiment in split-splot design. The factor tested was a type of microelements [n=5: Cu, Zn, Mn, Mo, B]. The microelements were foliar sprayed in a chelated form, as the series of Symfonia fertilizers. The study aimed at comparing the effect of five agricultural-engineering basic microelements on the contents and protein composition of the seeds of Aura cultivar. The fertilization applied, boron and manganese in particular, showed an effect on the increase in the contents of total protein in bean seeds. It also modified the fractional composition of the bean seed protein. There was observed a clear increase in the fraction of albumins and globulins in seeds as a result of the microelements applied, except for boron. The fertilization with molybdenum, boron, copper and zinc reduced the content of glutelins, and the sum of glulelins and prolamines in the bean seeds.

[125I] Thyroxine has been covalently bound to the thyroxine binding site in thyroxine-binding globulin by reaction with the bifunctional reagent, 1,5-difluoro-2,4-dinitrobenzene. An average of 0.47 mol of [125I] thyroxine was incorporated per mol protein; nonspecific binding amounted to 8%. A labeled peptide fragment was isolated from a proteolytic digest of the derivatized protein by HPLC and its amino acid composition was determined. Comparison with the amino acid sequence of thyroxine-binding globulin indicated partial correspondence of the labeled peptide with two possible regions in the protein. These regions also coincide with part of the barrel structure present in the closely homologous protein, alpha 1-antitrypsin.

Ten male buffalo calves were used in the present study. The animals were housed in semi-open barn. Ration was composed of concentrate mixture and wheat straw according to NRC (1985). Animals were allowed to drink fresh water ad libitum. Plasma cortisol, total protein, albumin, globulin, urea, creatinine, GPT and GOT were determined at the end of thermoneutral and summer heat stress exposure periods. Rectal temperature and respiration rate were recorded daily during both periods whereas body weight was recorded weakly during each period. Summer heat stress induced significant increases in rectal temperature, respiration rate, plasma cortisol, albumin/globulin ratio, plasma urea-N, creatinine, GPT and GOT while total protein, albumin, globulin did not affect by summer heat stress. Body weight was decreased under heat stress in both summer seasons but increased with age. In conclusion, summer heat stress induced alterations in some physiological and biochemical parameters of blood and body weight of male buffalo calves, and the young calves were less tolerant to summer heat stress than the older calves.

The albumin/globulin ratio (AGR) has been widely reported to be a potential predictor of prognosis in digestive system cancers (DSCs), but convincing conclusions have not been made. Therefore, herein, we performed a meta-analysis of relevant studies regarding this topic to evaluate the prognostic value of AGR in patients with DSCs. Three databases, including PubMed, EMBase, and Web of science, were searched comprehensively for eligible studies through September 8, 2017. The outcomes of interest included overall survival (OS), disease-free survival (DFS), and cancer-specific survival (CSS). In our meta-analysis, pooled analysis of 13 studies with 9269 patients showed that a low AGR was significantly correlated with poor OS (HR = 1.94; 95% CI: 1.57-2.38; P digestive system cancers. A low pretreatment AGR may be a useful predictive prognostic biomarker in human digestive system cancers.

Endocrine disruption: In silico interactions between phthalate plasticizers and corticosteroid binding globulin.

Science.gov (United States)

Sheikh, Ishfaq A; Beg, Mohd A

2017-12-01

Endocrine disruption is a phenomenon when a man-made or natural compound interferes with normal hormone function in human or animal body systems. Endocrine-disrupting compounds (EDCs) have assumed considerable importance as a result of industrial activity, mass production of synthetic chemicals and environmental pollution. Phthalate plasticizers are a group of chemicals used widely and diversely in industry especially in the plastic industry, and many of the phthalate compounds have endocrine-disrupting properties. Increasing evidence indicates that steroid nuclear receptors and steroid binding proteins are the main targets of endocrine disruption. Corticosteroid-binding globulin (CBG) is a steroid binding protein that binds and transports cortisol in the blood circulation and is a potential target for endocrine disruption. An imbalance of cortisol in the body leads to many health problems. Induced fit docking of nine important and environmentally relevant phthalate plasticizers (DMP, BBP, DBP, DIBP, DnHP, DEHP, DINP, DnOP, DIDP) showed interactions with 10-19 amino acid residues of CBG. Comparison of the interacting residues of CBG with phthalate ligands and cortisol showed an overlapping of the majority (53-82%) of residues for each phthalate. Five of nine phthalate compounds and cortisol shared a hydrogen bonding interaction with the Arg-252 residue of CBG. Long-chain phthalates, such as DEHP, DINP, DnOP and DIDP displayed a higher binding affinity and formed a number of interactions with CBG in comparison to short-chain phthalates. The similarity in structural binding characteristics of phthalate compounds and native ligand cortisol suggested potential competitive conflicts in CBG-cortisol binding function and possible disruption of cortisol and progesterone homeostasis.

To determine changes in serum concentrations of total and free testosterone in young and middle-aged men.the healthy men (n=126) were divided 20-29 yr, 30-39 yr and 40-49 yr three groups,their serum levels of total testosterone (T), free testosterone (FT), luteinizing hormone (LH), follicle-stimulating hormone (FSH), sex hormone binding globulin (SHBG) and estradiol (E2) were detected. The results were statically analyzed. The results showed that the levels of serum T and FT was found significantly decreased in 30-39 yr group than in 20-29 yr group (15.06±13 nmol/L vs 20.41±86 nmol/L, P<0.01; 9.36±95 pg/L vs 11.48±88 pg/L, P<0.05; respectively). There were young trends that age-related decline in androgen levels. (authors)

Rapid increases in total lightning (also termed "lightning jumps") have been observed for many decades. Lightning jumps have been well correlated to severe and hazardous weather occurrence. The main focus of lightning jump work has been on the development of lightning algorithms to be used in real-time assessment of storm intensity. However, in these studies it is typically assumed that the updraft "increases" without direct measurements of the vertical motion, or specification of which updraft characteristic actually increases (e.g., average speed, maximum speed, or convective updraft volume). Therefore, an end-to-end physical and dynamical basis for coupling rapid increases in total flash rate to increases in updraft speed and volume must be understood in order to ultimately relate lightning occurrence to severe storm metrics. Herein, we use polarimetric, multi-Doppler, and lightning mapping array measurements to provide physical context as to why rapid increases in total lightning are closely tied to severe and hazardous weather.

Anthropogenic compounds with the capacity to interact with the steroid-binding site of sex hormone binding globulin (SHBG) pose health risks to humans and other vertebrates including fish. Building on studies of human SHBG, we have applied in silico drug discovery methods to identify potential binders for SHBG in zebrafish (Danio rerio) as a model aquatic organism. Computational methods, including; homology modeling, molecular dynamics simulations, virtual screening, and 3D QSAR analysis, successfully identified 6 non-steroidal substances from the ZINC chemical database that bind to zebrafish SHBG (zfSHBG) with low-micromolar to nanomolar affinities, as determined by a competitive ligand-binding assay. We also screened 80,000 commercial substances listed by the European Chemicals Bureau and Environment Canada, and 6 non-steroidal hits from this in silico screen were tested experimentally for zfSHBG binding. All 6 of these compounds displaced the [ 3 H]5α-dihydrotestosterone used as labeled ligand in the zfSHBG screening assay when tested at a 33 μM concentration, and 3 of them (hexestrol, 4-tert-octylcatechol, and dihydrobenzo(a)pyren-7(8H)-one) bind to zfSHBG in the micromolar range. The study demonstrates the feasibility of large-scale in silico screening of anthropogenic compounds that may disrupt or highjack functionally important protein:ligand interactions. Such studies could increase the awareness of hazards posed by existing commercial chemicals at relatively low cost

A survey using questionnaires was made on 152 facilities from July through September 1984 to examine normal reference ranges of serum thyroxine binding globulin (TBG), thyroxine (TT 4 ), and triiodothyronine (TT 3 ). Normal reference ranges of TBG were in good agreement with each other, with the exception of four facilities showing high upper limits. An average value of the upper and lower limits in 83 facilities was 13.7 +- 1.9 μg/ml; and the standard deviation was 28.6 +- 2.8 μg/ml. Differences (approximately 10 %) in coefficient of variation were comparable to those (5.7-9.6 %) obtained from the previous survey. There were approximately 10 % differences in coefficient of variation for both TT 4 and TT 3 . (Namekawa, K.)

Total lymphoid irradiation (TLI) with antithymocyte globulin (ATG) is a unique regimen that prepares recipients for allogeneic hematopoietic cell transplantation by targeting lymph nodes, while sparing large areas of the bone marrow. TLI is reported to increase the frequency of CD4+CD25+FoxP3+ T-regulatory cells (Treg) relative to conventional T cells. In this study, barriers to hematopoietic stem cell (HSC) engraftment following this nonmyeloablative conditioning were evaluated. TLI/ATG resulted in profound lymphoablation but endogenous host HSC remained. Initial donor HSC engraftment occurred only in radiation exposed marrow sites, but gradually distributed to bone marrow outside the radiation field. Sustained donor engraftment required host lymphoid cells insofar as lymphocyte deficient Rag2γc−/− recipients had unstable engraftment compared with wild-type. TLI/ATG treated wild-type recipients had increased proportions of Treg that were associated with increased HSC frequency and proliferation. In contrast, Rag2γc−/− recipients who lacked Treg did not. Adoptive transfer of Treg into Rag2γc−/− recipients resulted in increased cell cycling of endogenous HSC. Thus, we hypothesize that Treg influence donor engraftment post-TLI/ATG by increasing HSC cell cycling, thereby promoting the exit of host HSC from the marrow niche. Our study highlights the unique dynamics of donor hematopoiesis following TLI/ATG, and the effect of Treg on HSC activity. PMID:24591203

The association of endogenous androgens and sex hormone-binding globulin (SHBG) with metabolic syndrome (MetS) and type 2 diabetes mellitus (T2DM) mostly 23562 refers to small and selected study samples with immunoassay-based measurements. Thus, we investigated the association of hormone levels with MetS and T2DM in women from a large population-based sample. A total of 2077 women from the Study of Health in Pomerania were assessed at baseline (N = 3160, 1997-2001) and 5-year follow-up (N = 1711, 2002-2006). We investigated associations of total testosterone (T) and androstenedione measured by liquid chromatography-tandem mass spectrometry, SHBG by immunoassay, and free T and free androgen index with MetS and T2DM. Baseline prevalence of MetS and T2DM was 23.1% (N = 365) and 9.5% (N = 196), with an incidence of 17.7 and 7.0 per 1.000 person-years, respectively. Cross-sectional analyses yielded inverse associations of SHBG with MetS (relative risk [RR], 0.67; 95% confidence interval [CI], 0.60-0.74) and T2DM (RR, 0.61; 95% CI, 0.50-0.74) after multivariable adjustment. In longitudinal analyses, only age-adjusted models showed an inverse association of baseline SHBG with incident MetS (RR, 0.61; 95% CI, 0.51-0.73) and T2DM (RR, 0.58; 95% CI, 0.43-0.78). Multivariable-adjusted models stratified by menopausal status revealed an inverse association between SHBG and incident MetS risk in postmenopausal women (RR, 0.65; 95% CI, 0.51-0.81). This longitudinal population-based study revealed independent inverse associations of SHBG with MetS and T2DM, suggesting low SHBG as a potential risk marker for cardiometabolic morbidity, especially among postmenopausal women.

Surface-enhanced Raman spectroscopy (SERS) of serum albumin and globulin were employed to detect hepatocellular carcinoma (HCC). Tentative assignments of SERS bands show specific biomolecular changes associated with cancer development. These changes include a decrease in relative amounts of tryptophan, glutamine, glycine, and serine, indicating excessive consumption of amino acids for protein duplication. Principal component analysis was also introduced to analyze the obtained spectra, resulting in both diagnostic sensitivity and specificity of 100%. More importantly, it reveals that this method can detect HCC patients with alpha-fetoprotein negative test results, suggesting its great potential as a new alternative to detect HCC.

To compare the changes induced by oral versus transdermal estrogen therapy on the total and free serum concentrations of testosterone (T), thyroxine (T4), and cortisol (C) and the concentrations of their serum binding globulins sex hormone-binding globulin, thyroxine-binding globulin, and cortisol-binding globulin in naturally menopausal women. Randomized, open-label, crossover. Interventions included a 6-week withdrawal from previous hormone therapy (baseline), followed in randomized order by 12 weeks of oral conjugated equine estrogens (CEE) (0.625 mg/d) and 12 weeks of transdermal estradiol (TD E2) (0.05 mg/d), with oral micronized progesterone (100 mg/d) given continuously during both transdermal estrogen therapy regimens. Twenty-seven women were enrolled in the study, and 25 completed both treatment periods. The mean(SD) percentage changes from baseline of sex hormone-binding globulin, total T, and free T with oral CEE were +132.1% (74.5%), +16.4% (43.8%), and -32.7% (25.9%), respectively, versus +12.0% (25.1%), +1.2% (43.7%), and +1.0% (45.0%) with TD E2. The mean (SD) percentage changes of thyroxine-binding globulin, total T4, and free T4 with oral CEE were +39.9% (20.1%), +28.4% (29.2%), and -10.4% (22.3%), respectively, versus +0.4% (11.1%), -0.7% (16.5%), and +0.2% (26.6%) with TD E2. The mean (SD) percentage changes of cortisol-binding globulin, total C, and free C with oral CEE were +18.0% (19.5%), +29.2% (46.3%), and +50.4% (126.5%), respectively, versus -2.2% (11.3%), -6.7% (30.8%), and +1.8% (77.1%) with TD E2. Concentrations of all hormones and binding globulins were significantly different (P < or = 0.003) during administration of oral versus transdermal estrogen therapy, except for free T4 and free C. Compared with oral CEE, TD E2 exerts minimal effects on the total and free concentrations of T, T4, and C and their binding proteins.

Testosterone and insulin-like growth factor-1 (IGF-1) are essential factors for the maintenance of bone health in men. However, the results for the association of testosterone and IGF-1 with bone parameters were not consistent in prior studies. We evaluated the relationship of testosterone, sex hormone-binding globulin (SHBG), and IGF-1 with bone mineral density (BMD) and bone turnover markers (BTMs) in Korean men. We enrolled 1227 men aged ≥50 years in this cross-sectional study. Serum levels of total testosterone (TT), SHBG, IGF-1, osteocalcin, and C-terminal cross-linking telopeptide of type I collagen (CTX) were measured. Free testosterone (FT) was calculated using Vermeulen's method. BMD was measured by dual-energy X-ray absorptiometry. TT level was not related to BMD or BTMs in the unadjusted model; however, after adjusting for SHBG and IGF-1, the association between TT and BTMs was significant (β = -0.139 for osteocalcin and β = -0.204 for CTX). SHBG levels were negatively associated with lumbar BMD, and positively associated with BTMs in all models. As SHBG level increased, the prevalence of osteopenia or osteoporosis defined by BMD significantly increased (OR of 1SD change, 1.24). IGF-1 levels were significantly related with BMD, but not with BTMs. Meanwhile, FT levels were positively associated with BMD and negatively associated with BTMs. In conclusion, SHBG levels were independently related with bone parameters and osteopenia in men aged ≥50 years. IGF-1 levels were positively associated with BMD, but not with BTMs. SHBG may play a role in regulating age-related bone loss in men after middle-age.

The extent of DNA-repair induced by UV-C irradiation was measured in peripheral unstimulated lymphocytes of 24 patients with aplastic anaemia at different stages of disease and compared with the results obtained in 92 controls. As parameter of the DNA-repair synthesis, the incorporation of (/sup 3/H)thymidine in the presence of 2 mmol/l hydroxyurea (HU) was taken. Of 19 patients tested after treatment with antilymphocyte globulin (ALG), 5 were in complete autologous haemopoietic remission, defined as > 1000 granulocytes/mm/sup 3/, > 100 000 platelets/mm/sup 3/ and a nontransfused haemoglobin value > 10 g%. 14 patients were in partial remission, defined as improvement of haemopoietic function, not meeting the criteria for complete remission. 4/5 patients in complete remission had normal DNA-repair synthesis, compared to 4/14 patients in partial remission. In 92 controls, a normal level was found in 70 cases. In 4/5 patients examined at diagnosis and at various intervals after ALG-treatment, DNA-repair synthesis was low at diagnosis. It increased after therapy and paralleled improvement of haemopoietic function to some extent. It is suggested that in aplastic anaemia there are different populations of lymphocytes with differing DNA-repair capacity; ALG treatment seems to favour expansion of the normal population, which is associated with improvement of haemopoietic function.

Primary infections with normal third stage larvae of Dictyocaulus filaria at a dose of 150 1/kg caused significant decrease in the levels of haemoglobin, blood glucose, serum total proteins, serum albumin, albumin/globulin ratio and increase in levels of total globulins and lactate dehydrogenase (LDH) activity in lambs. Almost similar changes in the above blood constituents excepting for haemoglobin, blood glucose and LDH activity were noticed in lambs immunised with two doses of gamma irradiation larvae and subsequently challenged with normal larvae of D. filaria at a dose of 150 1/kg. In both the infected groups, serum calcium, inorganic phosphorus, malate dehydrogenase and alkaline phosphatase activities were, however, not affected.

Full Text Available Abstract Background Hereditary Inclusion Body Myopathy (HIBM is an autosomal recessive, adult onset, non-inflammatory neuromuscular disorder with no effective treatment. The causative gene, GNE, codes for UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase, which catalyzes the first two reactions in the synthesis of sialic acid. Reduced sialylation of muscle glycoproteins, such as α-dystroglycan and neural cell adhesion molecule (NCAM, has been reported in HIBM. Methods We treated 4 HIBM patients with intravenous immune globulin (IVIG, in order to provide sialic acid, because IgG contains 8 μmol of sialic acid/g. IVIG was infused as a loading dose of 1 g/kg on two consecutive days followed by 3 doses of 400 mg/kg at weekly intervals. Results For all four patients, mean quadriceps strength improved from 19.0 kg at baseline to 23.2 kg (+22% directly after IVIG loading to 25.6 kg (+35% at the end of the study. Mean shoulder strength improved from 4.1 kg at baseline to 5.9 kg (+44% directly after IVIG loading to 6.0 kg (+46% at the end of the study. The composite improvement for 8 other muscle groups was 5% after the initial loading and 19% by the end of the study. Esophageal motility and lingual strength improved in the patients with abnormal barium swallows. Objective measures of functional improvement gave variable results, but the patients experienced improvements in daily activities that they considered clinically significant. Immunohistochemical staining and immunoblotting of muscle biopsies for α-dystroglycan and NCAM did not provide consistent evidence for increased sialylation after IVIG treatment. Side effects were limited to transient headaches and vomiting. Conclusion The mild benefits in muscle strength experienced by HIBM patients after IVIG treatment may be related to the provision of sialic acid supplied by IVIG. Other sources of sialic acid are being explored as treatment options for HIBM.

Genome wide association identifies common variants at the SERPINA6/SERPINA1 locus influencing plasma cortisol and corticosteroid binding globulin.

Full Text Available Variation in plasma levels of cortisol, an essential hormone in the stress response, is associated in population-based studies with cardio-metabolic, inflammatory and neuro-cognitive traits and diseases. Heritability of plasma cortisol is estimated at 30-60% but no common genetic contribution has been identified. The CORtisol NETwork (CORNET consortium undertook genome wide association meta-analysis for plasma cortisol in 12,597 Caucasian participants, replicated in 2,795 participants. The results indicate that <1% of variance in plasma cortisol is accounted for by genetic variation in a single region of chromosome 14. This locus spans SERPINA6, encoding corticosteroid binding globulin (CBG, the major cortisol-binding protein in plasma, and SERPINA1, encoding α1-antitrypsin (which inhibits cleavage of the reactive centre loop that releases cortisol from CBG. Three partially independent signals were identified within the region, represented by common SNPs; detailed biochemical investigation in a nested sub-cohort showed all these SNPs were associated with variation in total cortisol binding activity in plasma, but some variants influenced total CBG concentrations while the top hit (rs12589136 influenced the immunoreactivity of the reactive centre loop of CBG. Exome chip and 1000 Genomes imputation analysis of this locus in the CROATIA-Korcula cohort identified missense mutations in SERPINA6 and SERPINA1 that did not account for the effects of common variants. These findings reveal a novel common genetic source of variation in binding of cortisol by CBG, and reinforce the key role of CBG in determining plasma cortisol levels. In turn this genetic variation may contribute to cortisol-associated degenerative diseases.

Polar extracts of the stinging nettle (Urtica dioica L.) roots contain the ligans (+)-neoolivil, (-)-secoisolariciresinol, dehydrodiconiferyl alcohol, isolariciresinol, pinoresinol, and 3,4-divanillyltetrahydrofuran. These compounds were either isolated from Urtica roots, or obtained semisynthetically. Their affinity to human sex hormone binding globulin (SHBG) was tested in an in vitro assay. In addition, the main intestinal transformation products of plant lignans in humans, enterodiol and enterolactone, together with enterofuran were checked for their activity. All lignans except (-)-pinoresinol developed a binding affinity to SHBG in the in vitro assay. The affinity of (-)-3,4-divanillyltetrahydrofuran was outstandingly high. These findings are discussed with respect to potential beneficial effects of plant lignans on benign prostatic hyperplasia (BPH).

Nutritional Habits have changed significantly and junk foods have become widely popular, in recent years. The present study aimed to shed the light on the effect of potato chips and / or ketchup consumption on some biochemical parameters. Sixty four male and female albino rats were used in the study. Animals were maintained on 0.25 g potato chips/ rat and / or 0.125 g ketchup / rat, 5 days a week for 4 weeks. Potato chips showed the lowest body wt gain in the male rats after 4 weeks but, ketchup modulated this negative effect of the potato chips in the group of male animals fed on potato chips plus ketchup. Potato chips significantly decreased brain serotonin, liver glutathione (GSH) and catalase (CAT) in both sexes; brain dopamine, serum total proteins, albumin, total globulins, α 2 - and β 1 -globulins in the females and serum thyroxine (T 4 ) in the male rats. Ketchup apparently affected serum T 4 and A / G ratio in both sexes, brain dopamine and liver GSH in the males in addition to brain serotonin, serum total globulins and ?1-globulin in the female rats. Potato chips plus ketchup significantly changed T 4 , dopamine, GSH, CAT, α 1 and α 2 -globulins in both sexes; serotonin and β 1 -globulin in the male rats, total proteins and albumin in the females. It could be concluded that potato chips consumption might induce numerous adverse effects in various body organs

2000-01-01

Abstract A radioimmunoassay (RIA) for total corticosterone (CORT) in rat plasma requiring a plasma volume of 2 μl was established. The importance of inactivating plasma corticosteroid-binding globulin (CBG), denatured by heat, before measuring CORT was shown. The method was evaluated and shown...... the blood sampling procedure. The result showed that the method had a capacity to detect CORT concentrations comparable with previous reported basal concentrations. Finally, the possible stress inducing effect of the blood sampling procedure was examined using two groups of male rats housed under either...... conventional or enriched environmental conditions. The result indicated that conventional environment housing induces slightly stressed animals compared to enriched housing. Enriched housing may provide an environment that makes it possible for rats to compensate for a stressful situation, i.e., the blood...

Lymphocyte-depleting induction lowers acute rejection (AR) rates among high-immunologic risk (HIR) renal transplant recipients, including African Americans (AAs), retransplants, and the sensitized. It is unclear whether different HIR subgroups experience similarly low rates of AR. We aimed to describe the incidence of AR and de novo donor-specific antibody (dnDSA) among HIR recipients categorized by age, race, or donor type. All received antithymocyte globulin (ATG) induction and triple maintenance immunosuppression. A total of 464 HIR recipients from 2007 to 2014 were reviewed. AR and dnDSA rates at 1 year for the entire population were 14% and 27%, respectively. AR ranged from 6.7% among living donor (LD) recipients to 30% in younger AA deceased donor (DD) recipients. De novo donor-specific antibody at 1 year ranged from 7% in older non-AA LD recipients to 32% in AAs. AA race remained as an independent risk factor for AR among DD recipients and for dnDSA among all HIR recipients. Development of both AR and dnDSA within the first year was associated with a 54% graft survival at 5 years and was an independent risk factor for graft loss. Despite utilization of recommended immunosuppression for HIR recipients, substantial disparities exist among subgroups, warranting further consideration of individualized immunosuppression in certain HIR subgroups. © 2016 Steunstichting ESOT.

This study was designed to examine the levels of serum protein fractions and testosterone, in addition to histopathological changes of small intestine and liver of Japanese quail following feeding with diets containing different concentrations of boiled oil (BO). Male Japanese quails (n=120), arranged into four groups each of three replicates, were supplemented with BO at 1%, 2% and 4% at the expense of 4% cotton seed oil (CSO). At the end of the experiment (10 weeks), three birds from each replicate were slaughtered and serum, small intestine and liver were collected for the determination of total testosterone, total protein, albumin and globulin fractions and fat studying the histology of small intestine and liver. The data revealed that feeding with BO led to decrease of total proteins and β-globulins in addition to cellular damages of small intestine and liver. This effect was increased with increasing the BO concentration in the diet

A total number of 1600 fertile eggs from japanese quail birds were used in this study. The eggs were divided into eight groups then incubated. NDV and vite were administered to the groups of eggs in Ovo injection at day 14 from incubation. Hatchability, body weight, egg production and mortality were recorded weekly for each group. Five blood samples were collected weekly from each group to measure total serum proteins, albumin, globulin, T3, T4 and HI titre. The results of this work revealed an increase in total serum proteins, globulin, and a decrease in t3, T4 and albumin values of the in ove vaccinating groups. Also HI titre recorded higher values due to ovo vaccination alone or combined with vit. E. It was noticed that the group injected by inactive vaccine plus vit. E registered high increases in hatchability, body weight and egg production beside a decrease in mortality

Antithymocyte globulins (ATGs) are part of the immunosuppression arsenal currently used by clinicians to prevent or treat acute rejection in solid organ transplantation. ATG is a mixture of non-specific anti-lymphocyte immunoglobulins targeting not only T cell subsets but also several other immune and non-immune cells, rendering its precise immunoglobulin composition difficult to appreciate or to compare from one preparation to another. Furthermore, several mechanisms of action have been described. Taken together, this probably explains the efficacy and the side effects associated with this drug. Recent data suggest a long-term negative impact on allograft and patient outcomes, pointing out the need to better characterize the potential toxicity and the benefit-risk balance associated to this immunosuppressive therapy within large clinical trials. © The Author 2016.

Fractionated total lymphoid irradiation (TLI) has been used for attempts at induction of a donor-specific tolerant-like state in allograft recipients and for immunosuppressive effects. Cyclosporin A (Cy A) has been shown to suppress rejection of organ grafts in many species including man. The present study was designed to test the effectiveness of TLI in combination with either Cy A or rabbit anticynomolgus thymocyte globulin (ATG) and azathioprine. Thirty-one orthotopic cardiac allografts were performed using surface cooling and total circulatory arrest in outbred cynomolgus monkeys. TLI was administered preoperatively in fractions of 100 rad until a total of 600 or 1800 rad was achieved. Cy A was administered 17 mg/kg/day. All treatment groups demonstrated extended survival. Myocardial biopsies as early as 4 weeks were consistent with mild rejection in all treatment groups. No significant synergistic effect upon survival could be demonstrated utilizing TLI (1800 rad) plus ATG and azathioprine was associated with a high incidence of early death attributable to leukopenia and infection. Cy A alone or in combination with TLI was associated with the development of lymphoid malignancy

One hundred twenty-seven Jersey cows (1 to 6 years of age) within a 160.93-km radius of Baton Rouge, La, were selected at random over a 3-year period to determine serum values for total creatine kinase, aspartate transaminase, calcium, phosphorus, alkaline phosphatase, cholesterol, total protein, globulin, urea nitrogen, and glucose. Breed and age were partitioned as possible sources of variation. Seasonal temperature and management influences were taken into account by restricting the sampling area. Seasonal temperature and management influences along with reproductive status and stage of lactation, were randomized by sampling over the 3-year period. All serum values, except aspartate transaminase, urea nitrogen, and glucose were influenced by age. Serum cholesterol, total protein, and glucose were influenced by age. serum cholesterol, total protein, and globulin tended to increase with age, whereas creatine kinase, calcium, phosphorus, and alkaline phosphatase generally decreased with age.

A retrospective review of a consecutive series of spinal fusions comparing patient and procedural characteristics of patients who developed surgical site infections (SSIs) after spinal fusion. It is known that increased surgical time (incision to closure) is associated with a higher rate of postoperative SSIs. We sought to determine whether increased total anesthetic time (intubation to extubation) is a factor in the development of SSIs as well. In spine surgery for deformity and degenerative disease, SSI has been associated with operative time, revealing a nearly 10-fold increase in SSI rates in prolonged surgery. Surgical time is associated with infections in other surgical disciplines as well. No studies have reported whether total anesthetic time (intubation to extubation) has an association with SSIs. Surgical records were searched in a retrospective fashion to identify all spine fusion procedures performed between January 2010 and July 2012. All SSIs during that timeframe were recorded and compared with the list of cases performed between 2010 and 2012 in a case-control design. There were 20 (1.7%) SSIs in this fusion cohort. On univariate analyses of operative factors, there was a significant association between total anesthetic time (Infection 7.6 ± 0.5 hrs vs. no infection -6.0 ± 0.1 hrs, P operative time (infection 5.5 ± 0.4 hrs vs. no infection - 4.4 ± 0.06 hrs, P infections, whereas level of pathology and emergent surgery were not significant. On multivariate logistic analysis, BMI and total anesthetic time remained independent predictors of SSI whereas ASA status and operative time did not. Increasing BMI and total anesthetic time were independent predictors of SSIs in this cohort of over 1000 consecutive spinal fusions. 3.

Although antithymocyte globulin (ATG) had been widely used in hematopoietic stem cell transplantation from unrelated donor due to its ability to prevent acute and chronic graft-versus-host disease (GVHD), the comparative efficacy and safety of ATG-Thymoglobulin (ATG-T) and ATG-Fresenius (ATG-F) in patients undergoing HLA-mismatched allogeneic peripheral blood stem cell transplantation from unrelated donors (UR-PBSCT) has not been evaluated. Retrospective analysis of patients who underwent HLA-mismatched UR-PBSCT between January 2003 and December 2013 and received pre-transplant ATG-T at a total dose of 10 mg/kg or ATG-F at a total dose of 20 mg/kg was performed. Patients who received ATG-T (n = 23) or ATG-F (n = 28) had similar baseline demographic, disease, and transplant characteristics. There were no significant between-groups differences in the probability of acute GVHD (P = 0.721) and chronic GVHD (P = 0.439). ATG-F was associated with nonsignificant trends toward higher disease-free survival at 3-year follow-up compared with ATG-T (45.7 ± 11.1 vs 61.3 ± 9.7 %, respectively, P = 0.07). A significantly greater proportion of ATG-T patients experienced high fever than ATG-F patients (P < 0.01) during ATG infusion. There was no difference in the rate of infection between the two treatment groups. There were less adverse effects comparing ATG-F with ATG-T. ATG-T at a total dose of 10 mg/kg and ATG-F at a total dose of 20 mg/kg had a similar clinical outcome in the setting of HLA-mismatched UR-PBSCT.

Are the levels of total circulating cell-derived microparticles (cMPs) and circulating tissue factor-containing microparticles (cMP-TF) increased in patients with endometriosis? The levels of total cMP, but not cMP-TF, were higher in patients with endometriosis, and these were attributed to higher levels in patients with deep infiltrating endometriosis (DIE). Previous studies have reported elevated levels of total cMP in inflammatory conditions as well as higher levels of other inflammatory biomarkers in endometriosis. Increased expression of tissue factor (a transmembrane receptor for Factor VII/VIIa) in eutopic and ectopic endometrium from patients with endometriosis has been described. There is no previous data regarding total cMP and cMP-TF levels in patients with endometriosis. A prospective case-control study including two groups of patients was carried out. The E group included 65 patients with surgically confirmed endometriosis (37 with DIE lesions) and the C group comprises 33 women without surgical findings of any form of endometriosis. Patients and controls were recruited during the same 10-month period. Controls were the next patient without endometriosis undergoing surgery, after including two patients with endometriosis. Venous blood samples for total cMP and cMP-TF determinations were obtained at the time of surgery, before anesthesia at a tertiary care center. To assess total cMP, an ELISA functional assay was used and cMP-TF activity in plasma was measured using an ELISA kit. Total cMP levels in plasma were higher in the E group compared with the C group (P < 0.0001). The subanalysis of endometriosis patients with DIE or with ovarian endometriomas without DIE showed that total cMP levels were higher in the DIE group (P = 0.001). There were no statistically significant differences in cMP-TF levels among the groups analyzed. This is a preliminary study in which the sample size was arbitrarily decided, albeit in keeping with previous studies analyzing

The early experiment result in our hospital showed that anti-thymocyte globulin (ATG) inhibited the proliferation of lymphoid tumor cells in the T-cell tumors. We used the ATG as the part of the conditioning regimen and to evaluate the long-term anti-leukemia effect, the safety and complication in the patients with highly aggressive T-cell lymphomas. Twenty-three patients were enrolled into this study. At the time of transplant, six patients reached first or subsequent complete response, three patients had a partial remission and 14 patients had relapsed or primary refractory disease. The conditioning regimen consisted of ATG, total body irradiation, toposide and cyclophosphamide. The complete remission rate after transplant was 95.7%. At a median follow-up time of 25 months, 16 (69.6%) patients are alive and free from diseases, including nine patients in refractory and progressive disease. Seven patients died after transplant, five from relapse and two from treatment-related complications. The incidence of grades II–IV acute graft-vs-host disease (GvHD) was 39.1%. The maximum cumulative incidence of chronic GvHD was 30%. The most frequent and severe conditioning-related toxicities observed in 8 out of 23 patients were grades III/IV infections during cytopenia. Thus, ATG-based conditioning is a feasible and effective alternative for patients with highly aggressive T-cell tumors

Full Text Available The acute phase response is an important adaptive response to sepsis and injury. As anabolic steroids increase protein synthesis we postulated that these agents might also increase hepatic acute phase protein synthesis. Male Wistar rats were pretreated with testosterone or danazol for 48 h prior to caecal ligation and puncture (CLP. Thirty-six h following surgery the animals were killed and blood taken for full blood count, total protein, albumin, α, β and γ globulin fractions on serum electrophoresis, complement C3 and transferrin levels. Danazol increased the α1, α2 and β1 globulin serum protein fractions in comparison with no surgery and CLP alone groups. These results indicate that danazol increases plasma acute phase proteins, as measured by electrophoresis, in this model of intra-abdominal sepsis.

Full Text Available An epizootic outbreak of rabies occurred in 1995 in Ribeirão Preto, SP, with 58 cases of animal rabies (54 dogs, 3 cats and 1 bat confirmed by the Pasteur Institute of São Paulo, and one human death. The need to provide care to a large number of people for the application of equine rabies immune globulin (ERIG prevented the execution of the skin sensitivity test (SST and often also the execution of desensitization, procedures routinely used up to that time at the Emergency Unit of the University Hospital of the Faculty of Medicine of Ribeirão Preto, University of São Paulo (EU-UHFMRP-USP, a reference hospital for the application of heterologous sera. In view of our positive experience of several years with the abolition of SST and of the use of premedication before the application of antivenom sera, we used a similar schedule for ERIG application. Of the 1489 victims of animal bites, 1054 (71% received ERIG; no patient was submitted to SST and all received intravenously anti-histamines (anti-H1 + anti-H2 and corticosteroids before the procedure. The patients were kept under observation for 60 to 180 minutes and no adverse reaction was observed. On the basis of these results, since December 1995 ERIG application has been decentralized in Ribeirão Preto and has become the responsibility of the Emergency Unit of the University Hospital and the Central Basic Health Unit, where the same routine is used. Since then, 4216 patients have received ERIG (1818 at the Basic Health Unit and 2398 at the EU-UHFMRP, with no problems. The ideal would be the routine use of human rabies immune globulin (HRIG in public health programs, but this is problematic, because of their high cost. However, while this does not occur, the use of SST is no longer justified at the time of application of ERIG, in view of the clinical evidence of low predictive value and low sensitivity of SST involving the application of heterologous sera. It is very important to point out

The present study was carried out to investigate the modulatory effect of olive oil (5 ml/kg b.wt.) against the toxicological effects of repeated daily oral administration of the organophosphorus pesticides malaphos (137.5 mg/kg), mephosfolan (0.89 mg/kg) and phosfolan (1.0 mg/kg) for one, two and four weeks on certain biochemical parameters such as serum albumin, globulin and A/G ratio, low density lipoprotein-cholesterol (LDL-cholesterol), high density lipoprotein-cholesterol (HDL-cholesterol), total cholesterol, total protein, gamma glutamyl transferase ( GT) and plasma triglycerides. In addition, modulation of blood urea, creatinine and uric acid were observed through all the experimental intervals. Also, the serum concentration of triiodothyronine (T 3 ), thyroxine (T 4 ) and thyroid stimulating hormone (TSH) were determined.The data obtained revealed significant decrease in serum total protein, albumin, globulin and HDL-cholesterol while significant increase in serum albumin to globulin ratio (A/G), triglycerides, creatinine, urea, uric acid, LDL-cholesterol, total cholesterol and GT in all treated groups was observed. On the other hand, the data recorded imbalance in thyroid function as a result of pesticides treatments, which donated that each of the three pesticides increased TSH secretion, while malaphos caused significant decrease in both T 3 and T 4 levels, mephosfolan increased T 4 and decreased T 3 levels, whereas phosfolan pesticide decreased T 4 and increased T 3 levels after one, two and four weeks post-treatment.Administration of olive oil during treatment with malaphos, mephosfolan and phosfolan pesticides attenuates to a great extent the destructive effects of pesticides on the assayed parameters, this effect is attributed to the beneficial properties whom olive oil possess as anti-oxidative potential that may act to protect the body organs against the pesticides toxicity and also due to the amelioration of oxidative stress of free radicals.

Usually serum albumin is measured with dye-binding assay as bromocresol green (BCG) and bromocresol purple (BCP) methods. The aim of this paper was to examine the differences in albumin measurements between the Advia2400 BCG method (AlbBCG), Dimension RxL BCP (AlbBCP) and capillary zone electrophoresis (CZE). Albumin concentrations from 165 serum samples were analysed using AlbBCG, AlbBCP and CZE. CZE was employed to estimate different serum protein fractions. Influence of globulins on albumin concentration discrepancies between methods was estimated as well as the impact of the albumin method on aCa concentrations. Medcalc was employed for statistical analysis, setting a value of P albumin concentrations. AlbBCG were positively biased versus CZE (3.54 g/L). There was good agreement between CZE and ALbBCP (Albumin results from the BCP and BCG methods may result in unacceptable differences and clinical confusion, especially at lower albumin concentrations. Serum acute phase proteins contribute to overestimating the albumin concentration using AlbBCG.

Full Text Available The total solids content of feedstocks affects the performances of anaerobic digestion and the change of total solids content will lead the change of microbial morphology in systems. In order to increase the efficiency of anaerobic digestion, it is necessary to understand the role of the total solids content on the behavior of the microbial communities involved in anaerobic digestion of organic matter from wet to dry technology. The performances of mesophilic anaerobic digestion of food waste with different total solids contents from 5% to 20% were compared and the microbial communities in reactors were investigated using 454 pyrosequencing technology. Three stable anaerobic digestion processes were achieved for food waste biodegradation and methane generation. Better performances mainly including volatile solids reduction and methane yield were obtained in the reactors with higher total solids content. Pyrosequencing results revealed significant shifts in bacterial community with increasing total solids contents. The proportion of phylum Chloroflexi decreased obviously with increasing total solids contents while other functional bacteria showed increasing trend. Methanosarcina absolutely dominated in archaeal communities in three reactors and the relative abundance of this group showed increasing trend with increasing total solids contents. These results revealed the effects of the total solids content on the performance parameters and the behavior of the microbial communities involved in the anaerobic digestion of food waste from wet to dry technologies.

In literature there are many results which have shown that low dose radiation can stimulate many physiological processes of living organism. In our earlier paper it was shown that low dose of gamma radiation has a stimulative effect upon metabolic process in chickens hatched from eggs irradiated before incubation. This was proved by increase of body weight gain and body weight, as well as by increase of two enzymes activities in blood plasma (aspartate aminotransferase and alanine aminotransferase) which play an important role in protein metabolism. Therefore, an attempt was made to determine the effect of eggs irradiation by low dose gamma rays upon concentration of total proteins and protein fractions in the blood plasma of chickens hatched from irradiated eggs. The eggs of heavy breed chickens were irradiated with a dose of 0.15 Gy gamma radiation (60Co) before incubation. Along with the chickens which were hatched from irradiated eggs, there was a control group of chickens hatched from nonirradiated eggs. All other conditions were the same for both groups of chickens. Blood samples were taken from the right jugular vein on the 1 s t and 3 r d day, or from the wing vein on days 5 and 7 after hatching. The total proteins concentration in the blood plasma was determined by the biuret method using Boehringer Mannheim GmbH optimized kits. The protein fractions (albumin, α 1 -globulin, α 2 -globulin, β- and γ-globulins) were estimated electrophoretically on Cellogel strips. The total proteins concentration was significantly decreased in blood plasma of chickens hatched from irradiated eggs on days 3 (P t h day (P 2 -globulin was decreased on days 1 (P t h day of life. Obtained results indicate that low dose of gamma radiation has mostly inhibitory effect upon concentration of total proteins and protein fractions in the blood plasma of chickens hatched from irradiated eggs before incubation.

Studies were carried out on the interactions of uncharged latex beads (0.76 micrometer) with baby hamster kidney cells. Binding of beads to the cells occurred if the beads were coated by cold insoluble globulin (CIG) (plasma fibronectin) but not if the beads were coated by bovine albumin. Bovine albumin-coated beads did not bind to the cells even in the presence of excess CIG in the incubation medium. Binding of beads occurred randomly over the entire surfaces of cells in suspension.

During the period from June. 1969 to Dec. 1970, the serum protein electrophoretic patterns of 44 cases of various cancer patients have been studied to determine the alterations in serum protein fractions in patients who were responding to irradiation or those failing. The serum electrophoretic pattern could be observed as an indicator of prognosis or radiosensitivity. A blood sample was obtained prior to any treatment and the follow up sampling was performed 2 times during radiation therapy. Serum total protein was determined by the method of Wolfson and serum electrophoresis was carried out by using Spinoco Model R B electrophoresis system. The results were following: Seven cases out of cases of cervical cancer responding favorably to radiotherapy showed decreased in Alpha-2 globulin fraction were increased. A case whose third time serum electrophoretic pattern showed multiple myeloma type died 5 months after radiotherapy with bone metastasis. Four cases out of 9 cases of favorably responded breast cancer patients showed decreased in Alpha-2 globulin foraction compared with 2 cases of unfavorable response showed increased in Alpha-2 globulin fraction

Objective The association between type 2 diabetes and low testosterone has been well recognized. However, testosterone levels in men with prediabetes have been rarely reported. We aimed to investigate whether prediabetes was associated with an increased risk of testosterone deficiency. Methods This study included 1,306 men whose sex hormones was measured during a medical examination. Serum total testosterone and sex hormone-binding globulin were measured; free and bioavailable testosterone concentrations were calculated by Vermeulen’s formula. Prediabetes was defined by impaired fasting glucose (IFG), impaired postprandial glucose (IPG), or glycated hemoglobin (HbA1c) 5.7%-6.4%. Logistic regression was performed to obtain the odds ratios (OR) for subnormal total testosterone (prediabetic and diabetic men compared with normoglycemic individuals, while adjusting for age, BMI, waist circumference, and metabolic syndrome (MetS). Results Normoglycemia, prediabetes, and diabetes were diagnosed in 577 (44.2%), 543 (41.6%), and 186 (14.2%) men, respectively. Prediabetes was associated with an increased risk of subnormal total testosterone compared to normoglycemic individuals (age-adjusted OR=1.87; 95%CI=1.38-2.54). The risk remained significant in all multivariate analyses. After adjusting for MetS, the OR in prediabetic men equals that of diabetic patients (1.49 versus 1.50). IFG, IPG, and HbA1c 5.7%-6.4% were all associated with an increased risk of testosterone deficiency, with different levels of significance in multivariate analyses. However, neither prediabetes nor diabetes was associated with subnormal free testosterone in multivariate analyses. Conclusions Prediabetes is associated with an increased risk of testosterone deficiency, independent of obesity and MetS. After adjusting for MetS, the risk equals that of diabetes. Our data suggest that testosterone should be measured routinely in men with prediabetes. PMID:24069277

This study was designed to compare the effects of the anti-human T lymphocyte globulin (Fresenius, ATG-F)and rabbit anti-human thymocyte immunoglobulin (Genzyme, R-ATG)in the treatment of childhood aplastic anemia (AA) and their effects. A total of 59 children with aplastic anemia were analyzed in the present study, including 34 cases of severe aplastic anemia (SAA), 12 cases of very severe aplastic anemia (VSAA) and 13 cases of transfusion-dependent non-severe aplastic anemia (NSAA). While receiving immunosuppressive therapy (IST), 30 and 29 patients, with long-term oral supplement with cyclosporin A (CSA), androgen and Chinese traditional medicines, were treated with ATG-F and R-ATG, respectively. When it was necessary, some supportive cares such as component transfusion and infection control were also employed. Absolute counts of peripheral blood lymphocyte (ALC) at various time points were dynamically detected after ATG therapy. According to the International Aplastic Anemia Treatment and Effect standards. There were no statistically significant differences in the overall response rate (67%(20/30)vs. 69%(20/29), χ(2)=0.036, P=0.676) and the survival rate (87%(26/30)vs. 83%(24/29), χ(2)=0.173, P=0.676) between the ATG-F and R-ATG groups. There were significant and long-term ALC decrease after ATG therapy, the rate of ALC decrease in ATG-F and R-ATG group, the ALC only recovered to 47.8% (ATG-F group) and 47.4% (R-ATG group) of the pre-treatment level respectively. ATG-F 5 mg/(kg·d) and R-ATG 3.75 mg/(kg·d)could achieve similar effects in the treatment of childhood AA, through similar significant clearance of T cells. Therefore, all of these suggest that ATG-F and R-ATG might serve as the drugs of front-line choice for IST in childhood AA patients who do not have an available human leukocyte antigen identical related donor.

Preventing acute rejection (AR) after kidney transplantation is of utmost importance because an AR can have a negative impact on long-term allograft survival. Directory of Open Access Journals (DOAJ), Google Scholar, PubMed, EBSCO, and Web of Science have been searched. At the moment this can be done by using rabbit anti-thymocyte globulins (rATGs) as an induction therapy. However, because rATGs are associated with some deleterious side-effects, such as the opportunistic infections cytomegalovirus (CMV) and de novo post-transplant cancer, it is very important they are used optimally, i.e., at minimal doses that avoid many side-effects but still retain optimal treatment efficacy. Recent data show that the risk of CMV infection can be minimized using tacrolimus plus everolimus, and not tacrolimus plus mycophenolic acid, as the maintenance immunosuppression. The use of rATG is particularly valuable in; (a) sensitized patients; (b) in recipients from an expanded-criteria donor, thus enabling the introduction of calcineurin inhibitors at reduced doses; and (c) for patients where steroid avoidance is contemplated. However, we also need to consider that rATG may increase the risk of de novo cancer, even though recent data indicate this is unlikely and that any risk can be reduced by using mammalian target of rapamycin (mTOR) inhibitors instead of mycophenolic acid combined with low-dose calcineurin inhibitors. Even though rATGs do not improve long-term kidney-allograft survival, they may help reduce calcineurin-inhibitor dosage during the early post-transplant period and minimize the risk of AR.

Anti-T lymphocyte globulin Fresenius (rATG-F; ATG-Fresenius) and antithymocyte globulin (thymoglobulin), which are included in transplant protocols, are used to reduce the risk of chronic graft-versus-host disease (cGVHD) or suppress allograft rejection. Available clinical studies have been conducted in heterogenous patient populations and with different administration protocols including stem cell sources. Additionally, the pharmacokinetics of ATG is variable, and the clinically effective dose of rATG-F, in particular, is not exactly known. The aim of the study was to investigate the clinical outcomes of acute myeloid leukemia (AML) patients who underwent hemopoietic peripheral stem cell transplantation from full-matched sibling donors and given two different doses of r-ATG-F. This was a single-center, retrospective chart review conducted between July 2005 and July 2016. Sixty-nine consecutive AML patients who underwent transplant with fludarabine- and busulfan-based conditioning were included in the study. Patients in Group 1 received 15 mg/kg body weight rATG-F to 2013 (n = 46), and Group 2 received 30 mg/kg of rATG-F dose begining in 2013 to reduce to cGVHD (n = 23). Cyclosporine and methotrexate were used to treat acute GVHD (aGVHD) prophylaxis. Outcome parameters were compared between the groups. Although the recommended dose r-ATG-F had led to a decrease in the cumulative incidence of cGVHD (27 [58.7%] vs. 8 [34.8%]; p = .03), it also increased the infection rate at 1 year (3 [6.5%] vs. 4 [17.4%]; p = .02). The two groups were similar in terms of engraftment time, aGVHD, relapse, nonrelapse mortality, and rATG-F-related toxicity. A Cox regression model revealed that aGVHD III-IV was associated with increased nonrelapse mortality at 1 year (hazard ratio = 18.2; 95% confidence interval, 1.667-199.255; p = <.02). No patients developed rATG-F-related severe adverse events (Common Terminology Criteria grade 4 or 5). Dose difference of

Emerging Role of Corticosteroid Binding Globulin in Glucocorticoid-driven Metabolic Disorders

Full Text Available Glucocorticoid hormones (GCs are critical for survival since they ensure energy supply necessary to the body in an ever challenging environment. GCs are known to act on appetite, glucose metabolism, fatty acid metabolism and storage. However, in order to be beneficial to the body, GC levels should be maintained in an optimal window of concentrations. Not surprisingly, conditions of GC excess or deficiency, e.g. Cushing’s syndrome or Addison’s disease are associated with severe alterations of energy metabolism. Corticosteroid Binding Globulin (CBG, through its high specific affinity for GCs, plays a critical role in regulating plasma GC levels. Genetic studies in various species including humans have revealed that CBG is the major factor influencing inter-individual genetic variability of plasma GC levels, both in basal and stress conditions. Some, but not all of these genetic studies have also provided data linking CBG levels to body composition. The examination of CBG-deficient mice submitted to hyperlipidic diets unveiled specific roles for CBG in lipid storage and metabolism. The importance of CBG is even more striking when animals are submitted to high-fat diet combined to chronic stress, mimicking our occidental lifestyle. An influence of CBG on appetite has not been reported but remains to be more finely analyzed. Overall, a role of CBG in GC-driven metabolic disorders is emerging in recent studies. Although subtle, the influence of CBG in these diseases could open the way to new therapeutic interventions since CBG is easily accessible in the blood.

Full Text Available Biochemical and hematimetric indicators of inflammation and cell damage were correlated with bilirubin and hepatic and pancreatic enzymes in 30 chronic male alcoholics admitted into psychiatric hospital for detoxification and treatment of alcoholism. Aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, alkaline phosphatase, and total bilirubin were altered, respectively, in 90%, 63%, 87%, 23% and 23% of the cases. None of the indicators of inflammation (lactic dehydrogenase, altered in 16% of the cases; alpha-1 globulin, 24%; alpha-2 globulin, 88%; leucocyte counts, 28% was correlated with alterations of bilirubin or liver enzymes. Lactic dehydrogenase was poorly sensitive for detection of hepatocytic or muscular damage. Alterations of alpha-globulins seemed to have been due more to alcohol metabolism-induced increase of lipoproteins than to inflammation. Among indicators of cell damage, serum iron, increased in 40% of the cases, seemed to be related to liver damage while creatine phosphokinase, increased in 84% of the cases, related to muscle damage. Hyperamylasemia was found in 20% of the cases and significantly correlated with levels of bilirubin, alkaline phosphatase and gamma-glutamyltransferase. It was indicated that injuries of liver, pancreas, salivary glands, and muscle occurred in asymptomatic or oligosymptomatic chronic alcoholics.

Corticosteroid-binding globulin (CBG) binds most of the cortisol in circulation and is a non-functional member of the family of serine protease inhibitors (serpins) with an exposed elastase sensitive reactive centre loop (RCL). The RCL can be cleaved by human neutrophil elastase, released from activated neutrophils, and can also be cleaved at nearby site(s) by elastase released by Pseudomonas aeruginosa, and at two further sites, also within the RCL, by bovine chymotrypsin. Cleavage of the RCL results in a conformational change accompanied by a marked decrease in affinity for cortisol and hence its release at the site of proteolysis. These cleavages are irreversible and the similar half-lives of cleaved and intact CBG could mean that there may be some advantage in slowing the rate of CBG cleavage in acute inflammation thereby increasing the proportion of intact CBG in circulation. Here we show, for the first time, that pre-incubation of tethered human CBG with two monoclonal antibodies to the RCL of CBG protects against cleavage by all three enzymes. Furthermore, in plasma, pre-incubation with both RCL monoclonal antibodies delays neutrophil elastase cleavage of the RCL and one of these RCL monoclonal antibodies also delays bovine chymotrypsin cleavage of the RCL. These findings may provide a basis and rationale for the concept of the use of RCL antibodies as therapeutic agents to effectively increase the proportion of intact CBG in circulation which may be of benefit in acute inflammation.

BAL lymphocyte percentages, quantitated gallium-67 lung uptake, and SACE levels have all been proposed as measures of disease activity in sarcoidosis. We analyzed 32 paired sera and BAL fluids from sarcoidosis patients by high-resolution agarose electrophoresis to look for protein changes characteristic of systemic or local inflammation and compared the results with those from the above tests. Nine patients (group 1) had serum inflammatory protein changes and increased total protein, albumin, beta 1-globulin (transferrin), and gamma-globulin levels in fluid recovered by BAL. Thirteen patients (group 2) had normal protein levels in sera but abnormal protein levels in BAL specimens. Ten patients (group 3) had normal protein levels in sera and in BAL specimens. Patients in groups 1 and 2 had a disproportionate increase in beta 1-globulin (transferrin) and gamma-globulin levels in their BAL specimens. The BAL lymphocyte percentage changes paralleled the BAL protein level changes, suggesting relationships among the immunoregulatory role of these cells, increased local immunoglobulin synthesis, and the pathogenesis of altered alveolar permeability. Gallium-67 uptake was highest in patients with serum inflammatory protein changes. Thus, systemic inflammation may facilitate pulmonary gallium-67 uptake, possibly by changes in BAL fluid or serum transferrin saturation and/or kinetics. SACE levels showed no relationship to changes in the levels of serum or BAL proteins. These data suggest that the various proposed measures of disease activity reflect different aspects of inflammation in sarcoidosis

Cardiovascular disease (CVD) is the leading cause of death in the world and is the primary cause of mortality among Americans. One of the many reasons for the pathogenesis of CVD is attributed to eating diets high in saturated fat and refined carbohydrates and low in fruits and vegetables. Epidemiological evidence has supported a strong association between eating diets rich in fruits and vegetables and cardiovascular health. An experiment was conducted utilizing 24 adults with hypercholesterolemia and hypertriglyceridemia to evaluate the impact of drinking 20 fl oz of freshly squeezed orange juice daily for 90 days on blood pressure, lipid panels, plasma antioxidant capacity, metabolic hormones, lipid peroxidation, and inflammatory markers. Except for addition of drinking orange juice, subjects did not modify their eating habits. The findings suggested that drinking orange juice does not affect (P>.1) blood pressure, lipid panels, metabolic hormones, body fat percentage, or inflammatory markers. However, total plasma antioxidant capacity was significantly increased (Pjuice consumption. Drinking orange juice may protect the cardiovascular system by increasing total plasma antioxidant status and by lowering lipid peroxidation independent of other cardiovascular risk markers evaluated in this study.

Peas provide an excellent plant protein resource for human diets, but their proteins are less readily digestible than animal proteins. To identify the relationship between composition and in vitro digestibility of pea protein, eight pea varieties with a wide range of protein content (157.3-272.7 g kg(-1)) were determined for the proportion of albumins and globulins, their compositions using sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and in vitro protein digestibility (IVPD) before and after heat treatment using a multi-enzyme (trypsin, chymotrypsin and peptidase) method. The proportion of albumins based on total seed protein content decreased from 229 to 147 g kg(-1) as seed protein content increased from 157.3 to 272.7 g kg(-1), while the proportion of globulins increased from 483 to 590 g kg(-1). The IVPDs of eight raw pea seeds were 79.9-83.5%, with significant varietal variations, and those were improved to 85.9-86.8% by cooking. Albumins, including (pea albumins 2) PA2, trypsin inhibitor, lectin and lipoxygenase, were identified as proteolytic resistant proteins. Globulins were mostly digested by protease treatment after heating. The quantitative ratio of albumins and globulins, and the quantitative variations of albumin protein components, including lipoxygenase, PA2, lectins and trypsin inhibitors, appear to influence the protein digestibility of both raw and cooked pea seeds.

To understand the underlying molecular mechanism of the cholesterol-lowering effect of soybean 7S globulins, the interactions of their pepsin-released peptides (7S-peptides) with cell membrane models consisting of dipalmitoylphosphatidylcholine (DPPC), dioleoylphosphatidylcholine (DOPC), and cholesterol (CHOL) were systematically studied. The results showed that 7S-peptides were bound to DPPC/DOPC/CHOL liposomes mainly through van der Waals forces and hydrogen bonds, and the presence of higher CHOL concentrations enhanced the binding affinity (e.g., DPPC/DOPC/CHOL = 1:1:0, binding ratio = 0.114; DPPC/DOPC/CHOL = 1:1:1, binding ratio = 2.02). Compression isotherms indicated that the incorporation of 7S-peptides increased the DPPC/DOPC/CHOL monolayer fluidity and the lipid raft size. The presence of CHOL accelerated the 7S-peptide accumulation on lipid rafts, which could serve as platforms for peptides to develop into β-sheet rich structures. These results allow us to hypothesize that 7S-peptides may indirectly influence membrane protein functions via altering the membrane organization in the enterocytes.

In 3 experiments 29 cows were exposed to whole-body irradiation, using 9 MeV X-rays of a linear accelerator, with doses of 1.50 and 2.00 Gy or 60 Co gamma rays with a dose of 2.75 Gy, as a midline dose. 2 weeks prior to irradiation the first immunization was applied using human gamma globulin. 4 or 5 weeks after irradiation a second immunization was carried out. The antibody titres were investigated. The irradiation failed to affect the antibody titres after the first immunization. After the second immunization the antibody titres of the irradiated animals remained diminished significantly (α = 0.05). This has been attributed to a damage of the memory cell pool. (author)

Irradiations was performed at doses of 50, 100, 150 or 200 R according to groups, either, as single dose or as fractionated doses. It was established that changes begin to become evident only after total exposure of 100 R. It occurs a decrease of cellular constituents and more often than not an increase of total proteins and {gamma}-globulins.

Objective Analyze bile duct ligation effect upon glycosaminoglycans content and matrix metalloproteinase (MMPs activities. Methods Animals (6-8 weeks; n = 40 were euthanized 2, 7 or 14 days after bile duct ligation or Sham-surgery. Disease evolution was analyzed by body and liver weight, seric direct bilirubin, globulins, gamma glutamyl transpeptidase (GGT, alkaline phosphatase (Alk-P, alanine and aspartate aminotransferases (ALT and AST, tissue myeloperoxidase and MMP-9, pro MMP-2 and MMP-2 activities, histopathology and glycosaminoglycans content. Results Cholestasis caused cellular damage with elevation of globulins, GGT, Alk-P, ALT, AST. There was neutrophil infiltration observed by the increasing of myeloperoxidase activity on 7 (P = 0.0064 and 14 (P = 0.0002 groups which leads to the magnification of tissue injuries. Bile duct ligation increased pro-MMP-2 (P = 0.0667, MMP-2 (P = 0.0003 and MMP-9 (P<0.0001 activities on 14 days indicating matrix remodeling and establishment of inflammatory process. Bile duct ligation animals showed an increasing on dermatan sulfate and/or heparan sulfate content reflecting extracellular matrix production and growing mitosis due to parenchyma depletion. Conclusions Cholestasis led to many changes on rats’ liver parenchyma, as so as on its extracellular matrix, with major alterations on MMPs activities and glycosaminoglycans content.

The Steller sea lion, Eumetopias jubatus, has experienced regionally divergent population trends over recent decades. One potential mechanism for this disparity is that local factors cause reduced health and, therefore, reduced survival of individuals. The use of blood parameters to assess sea lion health may help to identify whether malnutrition, disease and stress are important drivers of current trends, but such assessments require species-specific knowledge of how parameters respond to various health challenges. We used principal components analysis to identify which key blood parameters (principal analytes) best described changes in health for temporarily captive juvenile Steller sea lions in known conditions. Generalized additive mixed models were used to estimate the changes in principal analytes with food intake, time in captivity and acute trauma associated with hot-iron branding and transmitter implant surgery. Of the 17 blood parameters examined, physiological changes for juvenile sea lions were best described using the following six principal analytes: red blood cell counts, white blood cell counts, globulin, platelets, glucose and total bilirubin. The white blood cell counts and total bilirubin declined over time in captivity, whereas globulin increased. Elevated red blood cell counts, white blood cell counts and total bilirubin and reduced globulin values were associated with lower food intake. After branding, white blood cell counts were elevated for the first 30 days, while globulin and platelets were elevated for the first 15 days only. After implant surgery, red blood cell counts and globulin remained elevated for 30 days, while white blood cell counts remained elevated during the first 15 days only. Glucose was unassociated with the factors we studied. These results were used to provide expected ranges for principal analytes at different levels of food intake and in response to the physical challenges of branding and implant surgery

Epidemiological studies consistently show that circulating sex hormone binding globulin (SHBG) levels are lower in type 2 diabetes patients than non-diabetic individuals, but the causal nature of this association is controversial. Genetic studies can help dissect causal directions...... used data from this SNP, or closely correlated SNPs, in 27 657 type 2 diabetes patients and 58 481 controls from 15 studies. We then used data from additional studies to estimate the difference in SHBG levels between type 2 diabetes patients and controls. The SHBG SNP rs1799941 was associated with type...... 2 diabetes [odds ratio (OR) 0.94, 95% CI: 0.91, 0.97; P = 2 x 10(-5)], with the SHBG raising allele associated with reduced risk of type 2 diabetes. This effect was very similar to that expected (OR 0.92, 95% CI: 0.88, 0.96), given the SHBG-SNP versus SHBG levels association (SHBG levels are 0.2...

Full Text Available Allogeneic hematopoietic stem cell transplantation (AHSCT is the treatment of choice for young patients with severe aplastic anemia (SAA. The association of antithymocyte globulin (ATG and cyclophosphamide (CY is the most frequently used conditioning regimen for this disease. We performed this retrospective study in order to compare the outcomes of HLA-matched sibling donor AHSCT in 41 patients with SAA receiving cyclophosphamide plus ATG (ATG-CY, N = 17 or cyclophosphamide plus busulfan (BU-CY, N = 24. The substitution of BU for ATG was motivated by the high cost of ATG. There were no differences in the clinical features between the two groups, including age, gender, cytomegalovirus status, ABO match, interval between diagnosis and transplant, and number of total nucleated cells infused. No differences were observed in the time to neutrophil and platelet engraftment, or in the risk of veno-occlusive disease and hemorrhage. However, there was a higher risk of mucositis in the BU-CY group (71 vs 24%, P = 0.004. There were no differences in the incidence of neutrophil and platelet engraftment, acute and chronic graft-versus-host disease, and transplant-related mortality. There was a higher incidence of late rejection in the ATG-CY group (41 vs 4%, P = 0.009. Although the ATG-CY group had a longer follow-up (101 months than the BU-CY group (67 months, P = 0.04, overall survival was similar between the groups (69 vs 58%, respectively, P = 0.32. We conclude that the association BU-CY is a feasible option to the conventional ATG-CY regimen in this population.

Full Text Available The aim of this study was to compare the effects of two levels of crude protein using poultry by-product meals (PBPM fed during late gestation on the performance, blood metabolites, and colostrum composition of Holstein dairy cows. Sixteen multiparous cows 26±6 d before expected calving were assigned randomly to two treatments containing 1 14% and 2 16% crude protein. The cow’s BCS was 3.56 ± 0.5 on average, at the beginning of the trial. Yields of milk, protein, lactose, fat, and SNF were not affected by prepartum dietary CP level. Colostrum composition (fat, CP and Total solids, blood metabolites (Ca, Glucose, Total protein, Albumin, Globulin and Urea N, and metabolic diseases incidence were not influenced by prepartum dietary CP level. There was no significant difference between treatments in body weight and BCS changes. As expected, blood urea N before calving was higher in the cows fed 16% CP diets. Serum cholesterol during prepartum and postpartum periods was significantly decreased as the CP increased in the diet. In general, although postpartum glucose level increased in cows which received 16% CP in the diet, it seems that no other obvious advantages over feeding the 14% CP diet are apparent. So feeding this last diet is recommended to close up cows.

PROGRESSIVE ALTERATION OF SERUM PROTEINS IN RATS SEVERAL MONTHS AFTER AN ACUTE OR PROTRACTED IRRADIATION

Delayed changes of the serum proteins in male Sprague Dawley rats that survived the acute radiation syndrome were investigated. Doses of Co/sup 60/ gamma ranging from LD/sub O/ to LD/sub 50/ were given to rats six to eight weeks of age. Paper electrophoreses and microdosage of proteins by the buiret method were performed on plasma proteins for 206 rats: 29 with acute irradiation; 73 chronic irradiation; 44 acute irradiation following cold acclimatization; and 80 normal animals. No significant variations in the total serum proteins were found in andy one group. Alpha globulins were found to be slightly above normal in some irradiated rats, but there was no significant variation in the BETA globulin fraction. Gamma globulins showed a marked and consistent increase following irradiation. Thus for observed protein chandges in irradiated rats have not proven to be dose dependent. It is suggested that the changes may provide a link between early irradiation syndrome and late effects. (H.M.G.)

Sex hormone-binding globulin (SHBG expression in ovarian carcinomas and its clinicopathological associations.

Directory of Open Access Journals (Sweden)

Ruixia Huang

Full Text Available Sex hormone-binding globulin (SHBG is known as a carrier protein. It is classically thought to be mainly synthesized in the liver and then secreted into the circulating system, where it binds to sex steroids with a high affinity and modulates the bio-availability of the hormones. Other organs known to produce SHBG include brain, uterus, testis, prostate, breast and ovary, and the local expressed SHBG may play an important role in tumor development. However, SHBG expression status and its clinicopathological significance in ovarian cancer cells are not reported yet. In our present study, we examined and found the variable SHBG expression in four ovarian cancer cell lines (OV-90, OVCAR-3, SKOV-3 and ES-2 by immunocytochemistry and Western blotting. We then extended our study to 248 ovarian carcinoma samples, which were collected at The Norwegian Radium Hospital, Oslo University Hospital with complete clinical information, and discovered that SHBG was variably expressed in these ovarian carcinomas. Higher level of SHBG expression was significantly associated with more aggressive histological subtype (p = 0.022, higher FIGO stage (p = 0.018 and higher histological grade (grade of differentiation, p = 0.020, although association between SHBG expression and OS/PFS was not observed. Our results demonstrate that ovarian cancer cells produce SHBG and higher SHBG expression in ovarian carcinoma is associated with unfavorable clinicopathological features.

Increasing Provasculature Complexity in the Arabidopsis Embryo May Increase Total Iron Content in Seeds: A Hypothesis

Full Text Available Anemia due to iron deficiency is a worldwide issue, affecting mainly children and women. Seed iron is a major source of this micronutrient for feeding, however, in most crops these levels are too low to meet daily needs. Thus, increasing iron allocation and its storage in seeds can represent an important step to enhance iron provision for humans and animals. Our knowledge on seed iron homeostasis is mainly based on studies performed in the model plant Arabidopsis thaliana, where iron accumulates in endodermis cells surrounding the embryo provasculature. It has been reported that cotyledon provasculature pattern complexity can be modified, thus we hypothesize that changes in the complexity of embryo vein patterns may affect total iron content in Arabidopsis seeds. This approach could be used as basis to develop strategies aimed to biofortify seeds.

In a randomized, international study comparing rabbit antithymocyte globulin (TMG) and basiliximab (BAS) induction in renal transplant recipients at risk for delayed graft function or acute rejection (n=278), TMG was associated with less acute rejection at 1 year. This study analyzed outcomes stratified by standard criteria donor (SCD), extended criteria donor (ECD), and hypertensive donor. Data-capture limitations necessitated defining ECD as donor age more than 60 years or 50 to 60 years with hypertension and renal insufficiency. Seventy-five recipients received ECD-kidneys (28.4% TMG vs. 25.6% BAS, P=NS) and 203 recipients received SCD-kidneys (72.6% TMG vs. 74.4% BAS, P=NS). Recipients of an ECD or hypertensive donor-kidney had similar outcomes between treatment groups. Recipients of an SCD-kidney treated with TMG had less rejection (odds ratio [OR] 0.48). Recipients of a normotensive donor-kidney treated with TMG had less rejection (OR 0.56). Recipients of a normotensive, SCD-kidney treated with TMG had less rejection (OR 0.47) and death (OR 0.17) than their counterparts treated with BAS. Contrary to its perceived niche in recipients of ECD-kidneys, TMG was most beneficial in patients who received a normotensive, deceased SCD kidney.

Full Text Available Over time, mankind has tried to find different ways of costs reduction. This subject which we are facing more often nowadays, has been detailed studied, without reaching a general model, and also efficient, regarding the costs reduction. Costs reduction entails a number of benefits over the entity, the most important being: increase revenue and default to the profit, increase productivity, a higher level of services / products offered to clients, and last but not least, the risk mitigation of the economic deficit. Therefore, each entity search different modes to obtain most benefits, for the company to succeed in a competitive market. This article supports the companies, trying to make known a new way of minimizing the total cost of acquisitions, by presenting some hypotheses about the increasing variable demand, proving them, and development of formulas for reducing the costs. The hypotheses presented in the model described below, can be maximally exploited to obtain new models of reducing the total cost, according to the modes of the purchase of entities which approach it.

Forty male albino rats were divided equally into four groups, the first group acted as control group, the second group was subjected to 5 Gy whole body gamma irradiation, the third group was injected intraperitoneally daily with soya oil (15 mg/kg b.w. for 14 days) before gamma irradiation and the fourth group was injected intraperitoneally daily with garlic oil (150/kg b.w. for 14 days) before gamma irradiation. Mortality percentage and body weight were recorded. Blood samples were collected one week post-gamma irradiation from all animals for biochemical analysis. Serum levels of thiobarbituric acid reactive substance (TBARS), total lipids, triglycerides and cholesterol were measured. Total proteins and albumin were measured using photometric methods. Globulin value was calculated by subtraction of albumin from total protein values. The results showed that gamma irradiation with dose level of 5 Gy induced retardation of live body weight and increased the mortality. The data also showed significant increases in TBARS, total lipids, triglycerides and cholesterol levels, whereas the levels of total proteins, albumin and globulin were significantly decreased. The soya oil or garlic oil injected pre-irradiation exerted noticeable amelioration in induced radiation changes on body weight, mortality, TBARS, lipid profiles and protein fractions

Avascular necrosis (AVN) may confer an increased risk of complications and readmission following total hip arthroplasty (THA). However, current risk-adjustment models do not account for AVN. A total of 1706 patients who underwent THA for AVN from 2011 to 2013 were selected from the American College of Surgeon's National Surgical Quality Improvement Program database and matched 1:1 to controls using a predetermined propensity score algorithm. Rates of 30-day medical and surgical complications, readmissions, and reoperations were compared between cohorts. Propensity-score logistic regression was used to determine independent associations between AVN and outcomes of interest. Patients with AVN had a higher rate of medical complications than those without AVN (20.3% vs 15.3%, respectively; PAvascular necrosis of the femoral head is an independent risk factor for transfusion up to 72 hours postoperatively and readmission up to 30 days following total hip replacement.

Rice seed storage protein (SSP) is an important source of nutrition and energy. Understanding the genetic basis of SSP content and mining favorable alleles that control it will be helpful for breeding new improved cultivars. An association analysis for SSP content was performed to identify underlying genes using 527 diverse Oryza sativa accessions grown in two environments. We identified more than 107 associations for five different traits, including the contents of albumin (Alb), globulin (Glo), prolamin (Pro), glutelin (Glu), and total SSP (Total). A total of 28 associations were located at previously reported QTLs or intervals. A lead SNP sf0709447538, associated for Glu content in the indica subpopulation in 2015, was further validated in near isogenic lines NIL(Zhenshan97) and NIL(Delong208), and the Glu phenotype had significantly difference between two NILs. The association region could be target for map-based cloning of the candidate genes. There were 13 associations in regions close to grain-quality-related genes; five lead single nucleotide polymorphisms (SNPs) were located less than 20 kb upstream from grain-quality-related genes ( PG5a , Wx , AGPS2a , RP6 , and, RM1 ). Several starch-metabolism-related genes ( AGPS2a , OsACS6 , PUL , GBSSII , and ISA2 ) were also associated with SSP content. We identified favorable alleles of functional candidate genes, such as RP6 , RM1 , Wx , and other four candidate genes by haplotype analysis and expression pattern. Genotypes of RP6 and RM1 with higher Pro were not identified in japonica and exhibited much higher expression levels in indica group. The lead SNP sf0601764762, repeatedly detected for Alb content in 2 years in the whole association population, was located in the Wx locus that controls the synthesis of amylose. And Alb content was significantly and negatively correlated with amylose content and the level of 2.3 kb Wx pre-mRNA examined in this study. The associations or candidate genes identified would

Full Text Available We studied the association of physical activity and adherence to the Mediterranean diet, in total antioxidant capacity (TAC. A random sample of 1514 men and 1528 women was selected from Attica region. Physical activity was assessed with a translated version of the validated “International Physical Activity Questionnaire” (iPAQ, and dietary intake through a validated Food Frequency Questionnaire (FFQ. Adherence to the Mediterranean diet was assessed by the MedDietScore that incorporated the inherent characteristics of this diet. TAC was positively correlated with the degree of physical activity (P<.05. TAC was also positively correlated with MedDietScore (r=0.24, P<.001. Stratified analysis by diet status revealed that the most beneficial results were observed to highly active people as compared to inactive, who also followed the Mediterranean diet (288  ±  70 μmol/L, 230  ±  50 μmol/L, resp., after adjusting for various confounders. Increased physical activity and greater adherence to the Mediterranean diet were associated with increased total antioxidant capacity.

Increased conformity offers diminishing returns for reducing total knee replacement wear.

Wear remains a significant problem limiting the lifespan of total knee replacements (TKRs). Though increased conformity between TKR components has the potential to decrease wear, the optimal amount and planes of conformity have not been investigated. Furthermore, differing conformities in the medial and lateral compartments may provide designers the opportunity to address both wear and kinematic design goals simultaneously. This study used a computational model of a Stanmore knee simulator machine and a previously validated wear model to investigate this issue for simulated gait. TKR geometries with different amounts and planes of conformity on the medial and lateral sides were created and tested in two phases. The first phase utilized a wide range of sagittal and coronal conformity combinations to blanket a physically realistic design space. The second phase performed a focused investigation of the conformity conditions from the first phase to which predicted wear volume was sensitive. For the first phase, sagittal but not coronal conformity was found to have a significant effect on predicted wear volume. For the second phase, increased sagittal conformity was found to decrease predicted wear volume in a nonlinear fashion, with reductions gradually diminishing as conformity increased. These results suggest that TKR geometric design efforts aimed at minimizing wear should focus on sagittal rather than coronal conformity and that at least moderate sagittal conformity is desirable in both compartments.

Ankylosing spondylitis (AS) is a chronic autoimmune spondyloarthropathy that primarily affects the axial spine and hips. Progressive disease leads to pronounced spinal kyphosis, positive sagittal balance, and altered biomechanics. The purpose of this study is to determine the complication profile of patients with AS undergoing total hip arthroplasty (THA). The Medicare sample was searched from 2005 to 2012 yielding 1006 patients with AS who subsequently underwent THA. Risk ratios (RRs) with 95% confidence intervals (CIs) were calculated for 90-day, 2-year, and the final postoperative follow-up for complications including hip dislocation, periprosthetic fracture, wound complication, revision THA, and postoperative infection. Compared to controls, AS patients had an RR of 2.50 (CI, 1.04-5.99) of THA component breakage at 90-days post-operatively and 1.99 (CI, 1.10-3.59) at 2-years. The RR of periprosthetic hip dislocation was elevated at 90 days (1.44; CI, 0.93-2.22) and significantly increased at 2-years (1.67; CI, 1.25-2.23) and overall follow-up (1.49; CI, 1.14-1.93). Similarly, the RR for THA revision was elevated at 90-days (1.46; CI, 0.97-2.18) and significantly increased at 2-years (1.69; CI, 1.33-2.14) and overall follow-up (1.51; CI, 1.23-1.85). Patients with AS are at increased risk for complications after THA. Altered biomechanics from a rigid, kyphotic spine place increased demand on the hip joints. The elevated perioperative and postoperative risks should be discussed preoperatively, and these patients may require increased preoperative medical optimization as well as possible changes in component selection and position to compensate for altered spinopelvic biomechanics.

This study aimed to evaluate changes in total body water (TBW) in soccer athletes using a deuterium oxide dilution method and bioelectrical impedance (BIA) formulas after 7 days of creatine supplementation. In a double-blind controlled manner, 13 healthy (under-20) soccer players were divided randomly in 2 supplementation groups: Placebo (Pla, n=6) and creatine supplementation (CR, n=7). Before and after the supplementation period (0.3 g/kg/d during 7 days), TBW was determined by deuterium oxide dilution and BIA methods. 7 days of creatine supplementation lead to a large increase in TBW (2.3±1.0 L) determined by deuterium oxide dilution, and a small but significant increase in total body weight (1.0±0.4 kg) in Cr group compared to Pla. The Pla group did not experience any significant changes in TBW or body weight. Although 5 of 6 BIA equations were sensitive to determine TBW changes induced by creatine supplementation, the Kushner et al. 16 method presented the best concordance levels when compared to deuterium dilution method. In conclusion, 7-days of creatine supplementation increased TBW determined by deuterium oxide dilution or BIA formulas. BIA can be useful to determine TBW changes promoted by creatine supplementation in soccer athletes, with special concern for formula choice. © Georg Thieme Verlag KG Stuttgart · New York.

Superfetation increases total fecundity in a viviparous fish regardless of the ecological context

Superfetation is the ability of females to simultaneously carry multiple broods of embryos at different developmental stages. This is an uncommon reproductive strategy that has evolved independently several times in viviparous fishes. The ecological conditions that favor higher degrees of superfetation (the presence of more simultaneous broods) still remain unclear. In this study we tested hypotheses about the potential effects of three particular ecological factors (water flow velocity, population density, and adult mortality) on superfetation. We used data on six populations of one fish species from the family Poeciliidae (Poeciliopsis baenschi) and a multimodel inference framework to test these hypotheses. We found no clear associations between the degree of superfetation and these ecological factors. Instead, we found a positive relationship between the total number of embryos carried by females and superfetation. Females increased their total fecundity as they overlapped more broods and this pattern was independent of the particular ecological conditions. Thus, in P. baenschi superfetation may facilitate a greater reproductive output. In addition, this positive relationship between total number of embryos and superfetation was stronger in small- and medium-sized females, whereas large females produced few or no simultaneous broods regardless of their total fecundity. The observed lack of association between superfetation and ecological variables is noteworthy because previous studies on other congeneric species have found that superfetation may vary as a function of water flow velocity or food availability. Our results indicate that the effect of particular selective factors on the degree of superfetation may differ among closely related species.

We describe a simple method for the immobilisation of anti-thyroxine antibody on to the surface of polystyrene tubes and a simple assay format for the quantitative estimation of total thyroxine in serum. The immobilisation of anti-thyroxine antibody was achieved through passive adsorption of normal rabbit gamma globulin and anti-rabbit antibody raised in goat, as immune bridges. This procedure ensured minimum utilisation of primary and secondary antibody as neat sera without precipitation or affinity purification. The developed assay system using these antibody coated tubes covers a range of 0-240 ng/mL of thyroxine with intra and inter assay variations of less than 10 %. (author)

The first-line formulation of antithymocyte globulin (ATG) remains unknown. We aimed to systematically review evidence to compare the efficacy and safety profiles of different ATGs. We did a systematic review and meta-analysis of randomized controlled trials (RCTs) and cohort controlled studies comparing horse and rabbit ATG in immunosuppressive therapy of treatment-naïve aplastic anemia. We searched The Cochrane Library, PubMed, EMBASE, ClinicalTrials.gov , and conference proceedings of American Society of Hematology and European Society for Blood and Marrow Transplantation annual meetings. The outcomes were 3-, 6-, and 12-month response; early mortality; relapse; and evolution. We pooled hazard ratios for relapse and odds ratios (ORs) for other outcomes using fixed-effect or random-effect models based on the heterogeneity. This study was registered with PROSPERO, number CRD42016036945. We included 1636 participants from three RCTs and 11 cohort controlled studies. Allocation to horse ATG increased 6-month response events by 86% compared with rabbit ATG. The benefit of horse ATG was mainly driven by increase in studies with non-Asian (OR 95% CI = 2.39 (1.54-3.69), p < 0.0001) and good partial response criterion (OR 95% CI = 2.73 (1.53-4.89), p = 0.0007). The early mortality and evolution were similar between groups. Compared with rabbit ATG, horse ATG had superior remission by 6 months and equivalent safety profiles in patients with treatment-naïve AA. Evidence for further responses beyond 6 to 12 months was limited.

Trunnionosis has reemerged in modern total hip arthroplasty for reasons that remain unclear. Bearing frictional torque transmits forces to the modular head-neck interface, which may contribute to taper corrosion. The purpose of this study is to compare frictional torque of modern bearing couples in total hip arthroplasty. Mechanical testing based on in vivo loading conditions was used to measure frictional torque. All bearing couples were lubricated and tested at 1 Hz for more than 2000 cycles. The bearing couples tested included conventional, highly crosslinked (XLPE) and vitamin E polyethylene, CoCr, and ceramic femoral heads and dual-mobility bearings. Statistical analysis was performed using Student t test for single-variable and analysis of variance for multivariant analysis. P ≤ .05 was considered statistically significant. Large CoCr metal heads (≥36 mm) substantially increased frictional torque against XLPE liners (P = .01), a finding not observed in ceramic heads. Vitamin E polyethylene substantially increased frictional torque compared with XLPE in CoCr and ceramic heads (P = .001), whereas a difference between conventional and XLPE was not observed (P = .69) with the numbers available. Dual-mobility bearing with ceramic inner head demonstrated the lowest mean frictional torque of all bearing couples. In this simulated in vivo model, large-diameter CoCr femoral heads and vitamin E polyethylene liners are associated with increased frictional torque compared with smaller metal heads and XLPE, respectively. The increased frictional torque of vitamin E polyethylene and larger-diameter femoral heads should be considered and further studied, along with reported benefits of these modern bearing couples.

Polar bears (Ursus maritimus) from several subpopulations undergo extended fasting during the ice-free season. However, the animals appear to conserve protein despite the prolonged fasting, though the mechanisms involved are poorly understood. We hypothesized that elevated concentrations of corticosteroid binding globulin (CBG), the primary cortisol binding protein in circulation, lead to cortisol resistance and provide a mechanism for protein conservation during extended fasting. The metabolic state (feeding vs. fasting) of 16 field sampled male polar bears was determined based on their serum urea to creatinine ratio (>25 for feeding vs. polar bears sampled. Serum CBG expression was greater in lactating females relative to non-lactating females and males. CBG expression was significantly higher in fasting males when compared to non-fasting males. This leads us to suggest that CBG expression may serve as a mechanism to conserve protein during extended fasting in polar bears by reducing systemic free cortisol concentrations. This was further supported by a lower serum glucose concentration in the fasting bears. As well, a lack of an enhanced adrenocortical response to acute capture stress supports our hypothesis that chronic hunger is not a stressor in this species. Overall, our results suggest that elevated serum CBG expression may be an important adaptation to spare proteins by limiting cortisol bioavailability during extended fasting in polar bears.

Intramuscular Immune Serum Globulin (IM ISG) is recommended as post-measles exposure prophylaxis (PEP) when administered within 6days of initial exposure, with variable effectiveness in preventing measles disease. Effectiveness of IM ISG PEP in preventing clinical measles was assessed during a 2014 measles outbreak among a religious-affiliated community in British Columbia, Canada. Fifty-five self-reporting measles susceptible contacts were offered exclusively IM ISG PEP within an eligibility period best surmised to be within 6days of initial measles case exposure. Clinical outcome of IM ISG PEP recipients was determined by selective active surveillance and case self-reporting. IM ISG PEP failure was defined as onset of a measles-like rash 8-21days post-IM ISG PEP. Post-IM ISG PEP measles IgG antibody level was tested in 8 recipients. Factors associated with measles disease were analyzed. Seventeen of 55 IM ISG PEP recipients developed clinically consistent measles in the following 8-21days, corresponding to an estimated crude protective effectiveness of 69%. In school aged children 5-18years, among whom potential exposure intensity and immune status confounders were considered less likely, estimated IM ISG PEP protective effectiveness was 50%. Age effectiveness against measles disease within 8-21days post-ISG administration was 69%. Accuracy of this estimated protective effectiveness is vulnerable to assumptions and uncertainties in ascertaining exposure details and pre-exposure immune status. Increasing the Canadian recommended measles IM ISG PEP dose from 0.25 to 0.5ml/kg (up to 15ml maximum volume) may increase protective effectiveness. Copyright © 2017 Elsevier Ltd.

In experiments on different animals a study was made of the effect of total-body γ-irradiation on binding of corticosteroids with blood plasma proteins. It was demonstrated that the increase in the number of physiologically active corticosteroids at the peak of radiation sickness is due to diminution of linking ability of corticosteroid-binding globulin of blood plasma and independent ot the total concentration of hormones in blood which is, evidently, a general radiobiological law

Serum protein electrophoresis is a useful screening test in equine laboratory medicine. The method can provide valuable information about changes in the concentrations of albumin and alpha-, beta-, and gamma-globulins and thereby help characterize dysproteinemias in equine patients. Reference values for horses using agarose gel as a support medium have not been reported. The purpose of this study was to establish reference intervals for serum protein concentrations in adult horses using agarose gel electrophoresis and to assess differences between warm-blooded and heavy draught horses. In addition, the precision of electrophoresis for determining fraction percentages and the detection limit were determined. Blood samples were obtained from 126 clinically healthy horses, including 105 Thoroughbreds and 21 heavy draught horses of both sexes and ranging from 2 to 20 years of age. The total protein concentration was determined by an automated biuret method. Serum protein electrophoresis was performed using a semi-automated agarose gel electrophoresis system. Coefficients of variation (CVs) were calculated for within-run and within-assay precision. Data from warm-blooded and draught horses were compared using the Mann-Whitney U test. Within-run and within-assay CVs were draught horses and so combined reference intervals (2.5-97.5%) were calculated for total protein (51.0-72.0 g/L), albumin (29.6-38.5 g/L), alpha(1)-globulin (1.9-3.1 g/L), alpha(2)-globulin (5.3-8.7 g/L), beta(1)-globulin (2.8-7.3g/L), beta(2)-globulin (2.2-6.0 g/L), and gamma-globulin (5.8-12.7 g/L) concentrations, and albumin/globulin ratio (0.93-1.65). Using agarose gel as the supporting matrix for serum protein electrophoresis in horses resulted in excellent resolution and accurate results that facilitated standardization into 6 protein fractions.

The 2008 World Health Organization classification proposed a new entity in childhood myelodysplastic syndrome, refractory cytopenia of childhood. However, it is unclear whether this morphological classification reflects clinical outcomes. We retrospectively reviewed bone marrow morphology in 186 children (median age 8 years; range 1-16 years) who were enrolled in the prospective study and received horse antithymocyte globulin and cyclosporine between July 1999 and November 2008. The median follow-up period was 87 months (range 1-146 months). Out of 186 patients, 62 (33%) were classified with aplastic anemia, 94 (49%) with refractory cytopenia of childhood, and 34 (18%) with refractory cytopenia with multilineage dysplasia. Aplastic anemia patients received granulocyte colony-stimulating factor more frequently and for longer durations than other patients (Paplastic anemia, 4 patients with refractory cytopenia of childhood, and 3 patients with refractory cytopenia with multilineage dysplasia. Although the cumulative incidence of total clonal evolution at ten years was not significantly different among the 3 groups, the cumulative incidence of monosomy 7 development was significantly higher in aplastic anemia than in the other groups (P=0.02). Multivariate analysis revealed that only granulocyte colony-stimulating factor administration duration of 40 days or more was a significant risk factor for monosomy 7 development (P=0.02). These findings suggest that even the introduction of a strict morphological distinction from hypoplastic myelodysplastic syndrome cannot eradicate clonal evolution in children with aplastic anemia.

Objectives: To review the current process for IFE at IALCH in the context of reflective testing and to examine the use of the alpha-2-globulin/alpha-1-globulin ratio as a predictor of a positive IFE result. Methods: Data for 1260 consecutive SPEP tests performed at the IALCH National Health Laboratory Service were collected between February and July 2011. SPEP and IFE were performed with a Sebia Hydrasys automated electrophoresis system. The alpha-2-globulin/alpha-1-globulin ratio was calculated using density of corresponding fractions on SPEP. Results: Analysis revealed that of the 1260 SPEPs performed during the analysis period, 304 IFEs were suggested by the reviewing pathologist. A total of 45 (15% of the suggested IFEs were subsequently requested by the attending clinicians. Almost half (46.5% (n = 20 of the suggested IFEs that were performed revealed the presence of a paraprotein. There was no statistically-significant difference between the alpha-2-globulin/alpha-1-globulin ratio for patients with positive or negative IFEs (p-value = 0.2. Conclusions: This study reveals the need for reflective addition of IFE testing by the laboratory following suspicious findings on SPEP.

T{sub 4}-binding globulin (TBG) is the major thyroid hormone transport protein in man. Inherited abnormalities in the level of serum TBG have been classified as partial deficiency, complete deficiency, and excess. Sequencing analysis of the TBG gene, located on Xq21-22, has uncovered the molecular defects causing partial and complete deficiency. However, the mechanism leading to inherited TBG excess remains unknown. In this study, two Japanese families, F-A and F-T, with inherited TBG excess were analyzed. Serum TBG levels in hemizygous males were 58 and 44 {mu}g/mL, 3- and 2-fold the normal value, respectively. The molecule had normal properties in terms of heat stability and isoelectric focussing pattern. The sequence of the coding region and the promoter activity of the TBG gene were also indistinguishable between hemizygotes and normal subjects. The gene dosage of TBG relative to that of {beta}-globin, which is located on chromosome 11, and Duchenne muscular dystropy, which is located on Xp, was evaluated by coamplification of these target genes using polymerase chain reaction and subsequent quantitation by HPLC. The TBG/{beta}-globin ratios of the affected male and female of F-A were 3.13 and 4.13 times, respectively, that in the normal males. The TBG/Duchenne muscular dystrophy ratios were 2.92 and 2.09 times the normal value, respectively. These results are compatible with three copies of TBG gene on the affected X-chromosome. Similarly, a 2-fold increase in gene dosage was demonstrated in the affected hemizygote of F-T. A 3-fold tandem amplification of the TBG gene was shown by in situ hybridization of prometaphase and interphase chromosomes from the affected male with a biotinylated genomic TBG probe, confirming the gene dosage results. Gene amplification of TBG is the cause of inherited TBG excess in these two families. 35 refs., 3 figs., 2 tabs.

Full Text Available Low total testosterone (TT and sex hormone-binding globulin (SHBG concentrations have been associated with the metabolic syndrome (MetS in men, but the reported strength of association varies considerably.We aimed to investigate whether associations differ across specific subgroups (according to age and body mass index (BMI and individual MetS components.Two previously published meta-analyses including an updated systematic search in PubMed and EMBASE.Cross-sectional or prospective observational studies with data on TT and/or SHBG concentrations in combination with MetS in men.We conducted an individual participant data meta-analysis of 20 observational studies. Mixed effects models were used to assess cross-sectional and prospective associations of TT, SHBG and free testosterone (FT with MetS and its individual components. Multivariable adjusted odds ratios (ORs and hazard ratios (HRs were calculated and effect modification by age and BMI was studied.Men with low concentrations of TT, SHBG or FT were more likely to have prevalent MetS (ORs per quartile decrease were 1.69 (95% CI 1.60-1.77, 1.73 (95% CI 1.62-1.85 and 1.46 (95% CI 1.36-1.57 for TT, SHBG and FT, respectively and incident MetS (HRs per quartile decrease were 1.25 (95% CI 1.16-1.36, 1.44 (95% 1.30-1.60 and 1.14 (95% 1.01-1.28 for TT, SHBG and FT, respectively. Overall, the magnitude of associations was largest in non-overweight men and varied across individual components: stronger associations were observed with hypertriglyceridemia, abdominal obesity and hyperglycaemia and associations were weakest for hypertension.Associations of testosterone and SHBG with MetS vary according to BMI and individual MetS components. These findings provide further insights into the pathophysiological mechanisms linking low testosterone and SHBG concentrations to cardiometabolic risk.

The present study was conducted to investigate the harmful effects and biochemical changes caused by dimethoate, an organophosphorus insecticide, at two different doses which represents 1/50 of LD 5 0 (4.3 mg/kg body weight/day) or 1/10 of LD 5 0 (21.5 mg/kg body weight/day). After thirty days of daily oral administrations to male rats, serum total lipids, triglycerides, cholesterol and high density lipoprotein levels were estimated. Also, its toxic effects on serum total protein, albumin, globulin and glucose levels were studied. The glucose level at the early periods after the treatment with dimethoate using D-(U-I4C) glucose was studied. The results showed significant increases in serum total lipids, triglycerides, y-globulin and glucose levels. On the other hand, cholesterol, HDL, total protein and albumin levels in serum of rats were decreased after dimethoate treatment. In conclusion, the data obtained in the present study indicated that dimethoate has harmful effects on the parameters under investigation after thirty days of daily treatments and also on glucose level after few hours of its administration compared to control rats

Total knee arthroplasty (TKA) in people with knee osteoarthritis increases knee-specific and general physical function, but it has not been established if there is a relationship between changes in these elements of functional ability. This study investigated changes and relationships between knee biomechanics during walking, physical activity, and use of time after TKA. Fifteen people awaiting TKA underwent 3D gait analysis before and six months after surgery. Physical activity and use of time were determined in free-living conditions from a high resolution 24-h activity recall. After surgery, participants displayed significant improvements in sagittal plane knee biomechanics and improved their physical activity profiles, standing for 105 more minutes (p=0.001) and performing 64 min more inside chores on average per day (p=0.008). Changes in sagittal plane knee range of motion (ROM) and peak knee flexion positively correlated with changes in total daily energy expenditure, time spent undertaking moderate to vigorous physical activity, inside chores and passive transport (r=0.52-0.66, p=0.005-0.047). Restoration of knee function occurs in parallel and is associated with improvements in physical activity and use of time after TKA. Increased functional knee ROM is required to support improvements in total and context specific physical activity. © 2015 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Full Text Available (1 Background: Pediatric obesity continues to be a major public health issue. Poor food selection in the school cafeteria is a risk factor. Chocolate or strawberry flavored milk is favored by the majority of elementary school students. Previous health promotion efforts have led to increased selection of plain milk, but may compromise total milk purchased. In our study, we examined the effectiveness of small prizes as incentives to improve healthy food and beverage selection by elementary school students; (2 Methods: In a small Midwestern school district, small prizes were given to elementary school students who selected a “Power Plate” (PP, the healthful combination of a plain milk, a fruit, a vegetable and an entrée with whole grain over two academic school years; (3 Results: PP selection increased from 0.05 per student to 0.19, a 271% increase (p < 0.001. All healthful foods had increased selection with plain milk having the greatest increase, 0.098 per student to 0.255, a 159% increase (p < 0.001; (4 Total milk purchased increased modestly from 0.916 to 0.956 per student (p = 0.000331. Conclusion: Giving small prizes as a reward for healthful food selection substantially improves healthful food selection and the effect is sustainable over two academic years.

Full Text Available Determination of the physiological electrophoretic patterns in animals is very useful for clinicians in diagnosing healthy and sick animals. The objective of this study was to investigate the serum protein electrophoretic pattern in cows, sheep, and goats in order to evaluate the differences in the size and number of protein fractions between the evaluated ruminant species. Ten adult multiparous high-yielding dairy cows, 10 adult female sheep and 10 adult female goats were included in this study. All the evaluated animals were clinically healthy. Serum was analyzed for total serum protein concentrations, and for the relative and absolute values of protein fractions with calculation of albumin/globulin ratios. Serum protein fractions were separated by zone electrophoresis on buffered agarose gel. Serum protein electrophoresis identified 6 distinct bands, comprising albumin, alpha1- (α1, alpha2- (α2, beta1- (β1, beta2- (β2, and gamma- (γ globulins in cows. In sheep, serum proteins exhibited 6 fractions: albumin, α1-, α2-, β-, γ1- and γ2-globulins. In goats, serum proteins were separated into 5 fractions: albumin, α1-, α2-, β- and γ-globulins. Significant differences in the relative as well as absolute means were found for the albumin/globulin ratio and most of the protein fractions, except γ-globulins. No significant differences were found in the concentration of total proteins. These results describe the marked species differences in most of serum protein fractions between the evaluated groups of animals, and contribute to the current knowledge about the physiological electrophoretic pattern of serum proteins in ruminants, which can be used for diagnostic purposes.

To identify possibly independent associations of perinatal, sociodemographic and lifestyle factors with childhood total and visceral body fat. A representative sample of 2655 schoolchildren (9-13 years) participated in the Healthy Growth Study, a cross-sectional epidemiological study. Seventy-seven primary schools in four large regions in Greece. A sample of 1228 children having full data on total and visceral fat mass levels, as well as on anthropometric, dietary, physical activity, physical examination, socio-economic and perinatal indices, was examined. Maternal (OR=3·03 and 1·77) and paternal obesity (OR=1·62 and 1·78), maternal smoking during pregnancy (OR=1·72 and 1·93) and rapid infant weight gain (OR=1·42 and 1·96) were significantly and positively associated with children's increased total and visceral fat mass levels, respectively. Children's television watching for >2 h/d (OR=1·40) and maternal pre-pregnancy obesity (OR=2·46) were associated with children's increased total and visceral fat mass level, respectively. Furthermore, increased children's physical activity (OR=0·66 and 0·47) were significantly and negatively associated with children's total and visceral fat mass levels, respectively. Lastly, both father's age >46 years (OR=0·57) and higher maternal educational level (OR=0·45) were associated with children's increased total visceral fat mass level. Parental sociodemographic characteristics, perinatal indices and pre-adolescent lifestyle behaviours were associated with children's abnormal levels of total and visceral fat mass. Any future programme for childhood prevention either from the perinatal age or at late childhood should take these indices into consideration.

Highlights: •Combining solar panels and crops on the same land increases the total productivity. •Use of solar trackers permits to balance or promote food/energy production. •Controlling mode of trackers strongly affect the total production per unit area. •Dynamic agrivoltaic systems increases productivity without competing with food. -- Abstract: Agrivoltaic systems, consisting of the combination of photovoltaic panels (PVPs) with crops on the same land, recently emerged as an opportunity to resolve the competition for land use between food and energy production. Such systems have proved efficient when using stationary PVPs at half their usual density. Dynamic agrivoltaic systems improved the concept by using orientable PVPs derived from solar trackers. They offer the possibility to intercept the variable part of solar radiation, as well as new means to increase land productivity. The matter was analysed in this work by comparing fixed and dynamic systems with two different orientation policies. Performances of the resulting agrivoltaic systems were studied for two varieties of lettuce over three different seasons. Solar tracking systems placed all plants in a new microclimate where light and shade bands alternated several times a day at any plant position, while stationary systems split the land surface into more stable shaded and sunlit areas. In spite of these differences, transient shading conditions increased plant leaf area in all agrivoltaic systems compared to full-sun conditions, resulting in a higher conversion of the transmitted radiation by the crop. This benefit was lower during seasons with high radiation and under controlled tracking with more light transmitted to the crop. As expected, regular tracking largely increased electric production compared to stationary PVPs but also slightly increased the transmitted radiation, hence crop biomass. A large increase in transmitted radiation was achieved by restricting solar tracking around midday

Seasonal influence on biochemical profile and serum protein electrophoresis for Boa constrictor amarali in captivity

LFN Silva

Full Text Available Similarly to other reptiles, snakes are ectothermic animals and depend exclusively on the environment for the maintenance of their physiological, biochemical and immunological processes. Thus, changes in biochemical values can be expected due to seasonal influence. Twenty-two adult specimens of Boa constrictor amarali kept in captivity were used. Blood collections were done in two different seasons: winter (July 2004 and summer (January 2005 for the following assays: uric acid, aspartate aminotransferase (AST, glucose, cholesterol, total protein, and serum protein electrophoresis. The mean biochemical results found in summer and winter, respectively, were: 6.3 ± 3.4 and 11.3 ± 6.2 mg/dL for uric acid; 28.7 ± 12.4 and 20.7 ± 16.2 UI/L for AST; 26.3 ± 17 and 17.4 ± 6.8 mg/dL for glucose; 67.3 ± 30.2 and 69.7 ± 38.5 mg/dL for cholesterol; and 5.9 ± 1.6 and 5.9 ± 1.4 g/dL for total protein. Results regarding electrophoresis in summer and winter, respectively, were: 1.9 ± 0.7 and 2.4 ± 0.6 g/dL for albumin; 0.7 ± 0.2 and 0.5 ± 0.2 g/dL for α-globulin; 1.5 ± 0.5 and 1.7 ± 0.6 g/dL for β-globulin; and 1.8 ± 0.5 and 1.5 ± 0.5 g/dL for g-globulin. In the summer, there was a significant increase in AST and a decrease in uric acid (p < 0.05. Serum protein electrophoresis showed a significant increase in α-globulin fraction (p < 0.05 in the same season. There were not significant differences between seasons for the remaining variables. Based on these results, the period of the year must be considered in the interpretation of some biochemical values for these animals.

Microalgae are an attractive biofuel feedstock because of their high lipid to biomass ratios, lipid compositions that are suitable for biodiesel production, and the ability to grow on varied carbon sources. While algae can grow autotrophically, supplying an exogenous carbon source can increase growth rates and allow heterotrophic growth in the absence of light. Time course analyses of dextrose-supplemented Chlorella vulgaris batch cultures demonstrate that light availability directly influences growth rate, chlorophyll production, and total lipid accumulation. Parallel photomixotrophic and heterotrophic cultures grown to stationary phase reached the same amount of biomass, but total lipid content was higher for algae grown in the presence of light (an average of 1.90 mg/mL vs. 0.77 mg/mL over 5 days of stationary phase growth).

Biochemical and haematological parameters are increasingly used to diagnose disease in green sea turtles. Specific clinical pathology tools, such as plasma protein electrophoresis analysis, are now being used more frequently to improve our ability to diagnose disease in the live animal. Plasma protein reference intervals were calculated from 55 clinically healthy green sea turtles using pulsed field electrophoresis to determine pre-albumin, albumin, α-, β- and γ-globulin concentrations. The estimated reference intervals were then compared with data profiles from clinically unhealthy turtles admitted to a local wildlife hospital to assess the validity of the derived intervals and identify the clinically useful plasma protein fractions. Eighty-six per cent {19 of 22 [95% confidence interval (CI) 65-97]} of clinically unhealthy turtles had values outside the derived reference intervals, including the following: total protein [six of 22 turtles or 27% (95% CI 11-50%)], pre-albumin [two of five, 40% (95% CI 5-85%)], albumin [13 of 22, 59% (95% CI 36-79%)], total albumin [13 of 22, 59% (95% CI 36-79%)], α- [10 of 22, 45% (95% CI 24-68%)], β- [two of 10, 20% (95% CI 3-56%)], γ- [one of 10, 10% (95% CI 0.3-45%)] and β-γ-globulin [one of 12, 8% (95% CI 0.2-38%)] and total globulin [five of 22, 23% (8-45%)]. Plasma protein electrophoresis shows promise as an accurate adjunct tool to identify a disease state in marine turtles. This study presents the first reference interval for plasma protein electrophoresis in the Indo-Pacific green sea turtle.

Full Text Available In this study, serum biochemistry and native protein electrophoresis in newborn calves with diarrhea and arthritis, were performed in order to evaluate the changes along with clinical findings for their possible application in the diagnosis and prognosis of disease. Based on clinical examination, animals were allotied into two groups comprising either diseased or healthy animals. Urea, creatinine, ALT, AST, LDH, albumin, total protein, glucose, total cholesterol, uric acid and iron levels were determined in the sera. Serum protein native polyacrilamide gel electrophoresis (nPAGE was performed followed by protein band ratio estimation supported with densitometry at 596 nm. Differences between the average mean of healthy and diseased animals were compared statistically (Kruskal-Walley test. In this study a decrease in serum glucose and cholesterol values (p<0.001, increase in urea, LDH levels and α1-and α2-globulin levels (p<0.01 and p<0.05 respectively were found to be associated with the disease. As a result, the observed significant changes in biochemical parameters and clinical investigation in calves, suggesting acute inflammation causing the decrease in glucose and increase in α-globulins, may be of prognostic value.

High dietary protein diets are widely used to manage overweight and obesity. However, there is a lack of consensus about their long-term efficacy and safety. Therefore, the aim of this study was to assess the effect of long-term high-protein consumption on body weight changes and death outcomes in subjects at high cardiovascular risk. A secondary analysis of the PREDIMED trial was conducted. Dietary protein was assessed using a food-frequency questionnaire during the follow-up. Cox proportional hazard models were used to estimate the multivariate-adjusted hazard ratio (HR) and 95% confidence intervals (95%CI) for protein intake in relation to the risk of body weight and waist circumference changes, cardiovascular disease, cardiovascular death, cancer death and total death. Higher total protein intake, expressed as percentage of energy, was significantly associated with a greater risk of weight gain when protein replaced carbohydrates (HR: 1.90; 95%CI: 1.05, 3.46) but not when replaced fat (HR: 1.69; 95%CI: 0.94, 3.03). However, no association was found between protein intake and waist circumference. Contrary, higher total protein intake was associated with a greater risk of all-cause death in both carbohydrate and fat substitution models (HR: 1.59; 95%CI: 1.08, 2.35; and HR: 1.66; 95%CI: 1.13, 2.43, respectively). A higher consumption of animal protein was associated with an increased risk of fatal and non-fatal outcomes when protein substituted carbohydrates or fat. Higher dietary protein intake is associated with long-term increased risk of body weight gain and overall death in a Mediterranean population at high cardiovascular risk.

Full Text Available Passive immunity transfer (PIT evaluation is an essential tool for the maintenance of healthy calves during the first months of life. Since lactation number and breed have been proven to influence immunoglobulin levels in colostrum, the aim of this study was to evaluate PIT from primiparous and multiparous Canchim cows to their calves. Blood samples were collected from the calves before colostrum intake and 1, 2, 7, 15 and 30 days thereafter, while colostrum samples from the cows were taken immediately after parturition. Activities of gamma-glutamyl transferase (GGT, alkaline phosphatase (ALP, and concentrations of total protein, albumin, globulins, immunoglobulin A (IgA, immunoglobulin G (IgG, total and ionized calcium, inorganic phosphorus, magnesium, sodium and potassium were evaluated in calves' serum and activities of GGT and ALP and concentrations of total protein, IgA and IgG were assessed in cow's colostrum whey. Immunoglobulins concentrations were evaluated by electrophoresis in polyacrylamide gels. Serum biochemistry evaluations revealed an increase in gamma-glutamyl transferase and alkaline phosphatase activities and in total protein, globulins, immunoglobulin A and immunoglobulin G levels in calves' serum after colostrum intake. Only total protein and light chain immunoglobulin G levels in colostrum whey were affected by the cows' lactation number. Phosphorus and magnesium levels in blood serum increased after colostrum intake, while sodium and potassium levels oscillated in the experimental period. PIT was influenced by the cows' lactation number but was efficient in both groups.

Full Text Available Background. The pretreatment albumin and globulin ratio (AGR was an inflammation-associated factor which was related to the overall survival in various malignancies. The aim of this study was to evaluate the prognostic value of AGR in patients with gastric cancer. Method. This retrospective study included 862 cases pathologically diagnosed with gastric cancer. All patients were randomly divided into the testing group (431 cases and validation group (431 cases. The relationships of AGR with clinicopathologic characteristics and prognosis were analyzed by Kaplan-Meier and Cox regression methods. Results. In the testing group, the median overall survival was 26.90 months and the cutoff value of AGR was 1.50 based on R language. Kaplan-Meier analysis showed that lower AGR was correlated with poorer overall survival. Multivariate analysis demonstrated that AGR was an independent prognostic factor for overall survival (HR: 0.584, 95% CI = 0.351–0.973, and p = 0.039. In the validation group, the median overall survival was 24.10 months. Lower AGR (≤1.50 also had a significantly poorer overall survival by Kaplan-Meier analysis. According to multivariate analysis, the AGR was also confirmed to be an independent prognostic factor for overall survival (HR: 0.578, 95% CI = 0.373–0.897, and p = 0.015. Conclusions. Our study suggested that the pretreatment AGR could be a prognostic biomarker for overall survival in patients with gastric cancer.

To explore the influence of water fluoride exposure on sex hormone binding globulin (SHBG) and testosterone in adult male. Cross-sectional study was conducted in three villages of Tongxu county including high fluoride group (HFG), defluoridation project group (DFPG) and control group (CG) based on the fluoride concentration in drinking water. Adult male who were born and raised in the village and aged 18 - 50 years old were recruited using cluster sampling. Fasting blood and morning urine samples were collected. The fluoride levels in drinking water and urine were detected by fluoride-ion selective electrode method. Serum SHBG level was determined using enzyme-linked immunosorbent assay (ELISA). The chemical luminescence immune analysis method was used to detect serum testosterone content. Serum SHBG level was 47.85 nmol/L in CG, 31.37 nmol/L in DFPG and 24.52 nmol/L in HFG respectively. There were significant difference among of three groups (P < 0.05). Serum testosterone level was 3.69 ng/ml in CG, 4.61 ng/ml in DFPG and 4.83 ng/ml in HFG respectively. Serum testosterone level in HFG was significantly higher than that in CG (P < 0.05). Serum SHBG level in HFG has positive correlation with serum testosterone (r = 0.230, P = 0.049), which has not been observed in DFPG and CG. Long-time fluorine exposure may affect serum SHBG and testosterone level in adult male.

Full Text Available PurposeSex hormone-binding globulin (SHBG modulates the availability of biologically active free sex hormones. The regulatory role of SHBG might be important in the relationship between hormone levels and the modification of lipid profiles in girls with precocious puberty. However, few studies have evaluated the relationship of SHBG, free estradiol index (FEI, and lipid levels in these girls.MethodsOne hundred and nine girls less than 8 years of age with pubertal development were enrolled. FEI was calculated with SHBG and estradiol (E2. We analyzed SHBG between peak luteinizing hormone (LH≥5 (IU/L (group 1 and LH<5 (IU/L (group 2 through a gonadotropin releasing hormone stimulation test.ResultsBody mass index (BMI standard deviation score (SDS was higher in group 2 than in group 1 (P=0.004. Serum SHBG levels did not differ and FEI was not higher in group 1 (P=0.122. Serum cholesterol, HDL, and LDL did not differ; however, triglyceride levels were higher in group 2 (P=0.023. SHBG was negatively correlated with bone age advancement, BMI, BMI SDS, and FEI, and was positively correlated with HDL. However, SHBG was not correlated with E2 or peak LH.ConclusionSerum SHBG itself might not be associated with precocious puberty in girls, but it might be related to BMI and lipid profiles. Further studies are needed to reveal the relationship between sex hormone and obesity in girls with precocious puberty.

Hollmen, T.; Franson, J.C.; Hario, Martti; Sankari, S.; Kilpi, Mikael; Lindstrom, K.

2001-01-01

During 1997–1999, we collected serum samples from 156 common eider (Somateria mollissima) females incubating eggs in the Finnish archipelago of the Baltic Sea. We used serum chemistry profiles to evaluate metabolic changes in eiders during incubation and to compare the health and nutritional status of birds nesting at a breeding area where the eider population has declined by over 50% during the past decade, with birds nesting at two areas with stable populations. Several changes in serum chemistries were observed during incubation, including (1) decreases in serum glucose, total protein, albumin, β‐globulin, and γ‐globulin concentrations and (2) increases in serum uric acid, creatine kinase, and β‐hydroxybutyrate concentrations. However, these changes were not consistent throughout the 3‐yr period, suggesting differences among years in the rate of carbohydrate, lipid, and protein utilization during incubation. The mean serum concentrations of free fatty acids, glycerol, and albumin were lowest and the serum α‐ and γ‐globulin levels were highest in the area where the eider population has declined, suggesting a role for nutrition and diseases in the population dynamics of Baltic eiders.

Horse antithymocyte globulin (h-ATG) (ATGAM(®) ) is the first choice of treatment in very severe patients with aplastic anemia who do not have any HLA matched sibling donor. h-ATG is a heterologous serum that may cause anaphylaxis. Alternative treatment strategies must be planned in case of hypersensitivity. Desensitization must be considered in patients without an alternative treatment of choice. We aimed to present the h-ATG desensitization protocol and consider its effectiveness in patients with aplastic anemia who are hypersensitized with h-ATG and do not have an alternative treatment of choice. Skin prick tests were performed with non-diluted solution in eight very severe patients with aplastic anemia who are followed up in Ege University Children's Hospital. Although skin prick test was found negative in these eight patients, different dilution h-ATG intradermal tests were performed and found positive in all patients. h-ATG desensitization program was started to these hypersensitized patients. Desensitization program was started to six male and two female very severe patients with aplastic anemia whose ages were between seven and 19 yr (median: 12.9 yr). All of the patients completed the desensitization program. While local reaction was seen in two patients, systemic reaction was seen in one patient and late reaction was seen in one patient during and after desensitization program. A successful desensitization program with h-ATG in children with aplastic anemia is presented. Even though there is not an exposure before to such high allergy potential heterologous serum, skin tests should be performed and desensitization must be started to patients who are hypersensitized to h-ATG. As the expected effectiveness of the treatment is so much, the desensitization protocol can be carried out safely and effectively with trained stuff although allergic reactions can be seen. © 2015 John Wiley & Sons A/S.

Human sex hormone-binding globulin gene expression- multiple promoters and complex alternative splicing

Directory of Open Access Journals (Sweden)

Rosner William

2009-05-01

Full Text Available Abstract Background Human sex hormone-binding globulin (SHBG regulates free sex steroid concentrations in plasma and modulates rapid, membrane based steroid signaling. SHBG is encoded by an eight exon-long transcript whose expression is regulated by a downstream promoter (PL. The SHBG gene was previously shown to express a second major transcript of unknown function, derived from an upstream promoter (PT, and two minor transcripts. Results We report that transcriptional expression of the human SHBG gene is far more complex than previously described. PL and PT direct the expression of at least six independent transcripts each, resulting from alternative splicing of exons 4, 5, 6, and/or 7. We mapped two transcriptional start sites downstream of PL and PT, and present evidence for a third SHBG gene promoter (PN within the neighboring FXR2 gene; PN regulates the expression of at least seven independent SHBG gene transcripts, each possessing a novel, 164-nt first exon (1N. Transcriptional expression patterns were generated for human prostate, breast, testis, liver, and brain, and the LNCaP, MCF-7, and HepG2 cell lines. Each expresses the SHBG transcript, albeit in varying abundance. Alternative splicing was more pronounced in the cancer cell lines. PL- PT- and PN-derived transcripts were most abundant in liver, testis, and prostate, respectively. Initial findings reveal the existence of a smaller immunoreactive SHBG species in LNCaP, MCF-7, and HepG2 cells. Conclusion These results extend our understanding of human SHBG gene transcription, and raise new and important questions regarding the role of novel alternatively spliced transcripts, their function in hormonally responsive tissues including the breast and prostate, and the role that aberrant SHBG gene expression may play in cancer.

Acute Exercise Increases Plasma Total Antioxidant Status and Antioxidant Enzyme Activities in Untrained Men

Full Text Available Antioxidant defences are essential for cellular redox regulation. Since free-radical production may be enhanced by physical activity, herein, we evaluated the effect of acute exercise on total antioxidant status (TAS and the plasma activities of catalase, glutathione reductase, glutathione peroxidase, and superoxide dismutase and its possible relation to oxidative stress resulting from exercise. Healthy untrained male subjects (=34 performed three cycloergometric tests, including maximal and submaximal episodes. Venous blood samples were collected before and immediately after each different exercise. TAS and enzyme activities were assessed by spectrophotometry. An increase of the antioxidant enzyme activities in plasma was detected after both maximal and submaximal exercise periods. Moreover, under our experimental conditions, exercise also led to an augmentation of TAS levels. These findings are consistent with the idea that acute exercise may play a beneficial role because of its ability to increase antioxidant defense mechanisms through a redox sensitive pathway.

Full Text Available Abstract Background Sex hormone-binding globulin (SHBG levels and sex hormones have been implicated in the pathogenesis of type 2 diabetes and cardiovascular diseases. As fatty liver has been suggested to be a major determinant of SHBG levels, we examined whether the associations of SHBG and testosterone with diabetes were independent of fatty liver. Methods We conducted a case–control study that included 300 diabetes cases (215 men and 85 women and 300 matched controls from the Saku cohort study. Diabetes was defined by either fasting plasma glucose levels ≥126 mg/dL, 2-h post-load glucose levels ≥200 mg/dL after a 75 g oral glucose tolerance test, or diabetes diagnosed by physicians. We fitted conditional logistic regression models to examine the associations between SHBG and total testosterone levels with diabetes by sex. To evaluate the impact of fatty liver, we used the fatty liver index (FLI, a validated measure derived from serum triglyceride levels, body mass index (BMI, waist circumference, and γ-glutamyltransferase levels. Results After adjusting for age, family history of diabetes, smoking, physical activity, BMI, and FLI, SHBG levels were inversely associated with diabetes among women (odds ratio [OR] comparing the highest with the lowest quartiles, 0.13 [95% confidence interval {CI}, 0.02–0.96], but not among men. Similar patterns were observed in a subgroup analysis restricted to postmenopausal women"(OR, 0.12 [95% CI, 0.01–1.17]. In contrast, testosterone levels were inversely associated with diabetes among men (OR, 0.45 [95% CI, 0.23–0.89], but not among women. Conclusions Our findings suggest that SHBG in women and testosterone in men may be inversely associated with diabetes.

1983-01-01

Seven bone marrow transplant recipients with acute lymphoblastic leukemia receiving a mean dose rate of 0.07 Gy/min of total body irradiation towards the pelvic midpoint and the lungs had an increased (p<0.01) overall death rate of 86 per cent compared with 33 per cent among 27 patients with acute non-lymphoblastic leukemia or acute lymphoblastic leukemia treated with a mean dose rate of 0.04 Gy/min. Among the patients receiving the higher dose rate there was an increased mortality in causes related to radiation toxicity like early septicemia, interstitial pneumonitis and pulmonary fibrosis, compared with all patients receiving the lower dose rate (p<0.01) and also with 10 patients from this group with acute lymphoblastic leukemia (p<0.02).

This experiment was carried out under hot environmental conditions, where temperature-humidity index was equivalent to 86 - 90 and 78 - 80 during day and night, respectively. Twelve bovine Baladi calves of 8 - 10 months old and 112 kg average initial live body weight were used in this study. The calves were divided into two groups of 6 animals each to study the effect of supplementation of dried whey milk on some blood biochemical and immunological indices and growth performance of calves under hot weather conditions of Egypt. The results showed that supplementation of dried whey milk to the diet of heat-stressed calves at the level of 150 g / calf / day reduced significantly each of respiration rate and rectal temperature as well as serum lipid concentrations and their fractions e.g. total cholesterol and phospholipids. Also, dried whey milk supplement caused a significant decline in both AST and ALT activities and reduced significantly alpha globulin concentration, while non-significant changes were observed in each of beta globulin, gamma globulin and immunoglobulin G. However, supplementing dried whey milk to growing calves increased significantly serum concentrations of total protein, albumin, calcium, phosphorous, T 3 and T 4 . Moreover, dried whey milk improved significantly both feed efficiency and daily gain of growing calves. It could be concluded that addition of dried whey milk to the diet reduced rectal temperature and respiration rate and induced an improvement in most blood biochemical parameters and growth performance of heat-stressed bovine Baladi calves.

To measure plasma concentration of ionized calcium in healthy green iguanas. Prospective study. 9 juvenile and 21 (10 male, 11 female) adult iguanas. Blood samples were obtained from each iguana, and plasma calcium, glucose, phosphorus, uric acid, total protein, albumin, globulin, potassium, and ionized calcium concentrations, aspartate transaminase (AST) activity, and pH were measured. Heparinized blood was used for measurement of ionized calcium concentration and blood pH. A CBC was also performed to assess the health of the iguanas. Significant differences were not detected among the 3 groups (juveniles, males, and females) with regard to ionized calcium concentration. Mean ionized calcium concentration measured in blood was 1.47 +/- 0.105 mmol/L. Significant differences were detected between juveniles and adults for values of phosphorus, glucose, total protein, albumin, globulin, and AST activity. Ionized calcium concentration provides a clinical measurement of the physiologically active calcium in circulation. Evaluation of physiologically active calcium in animals with suspected calcium imbalance that have total plasma calcium concentrations within reference range or in gravid animals with considerably increased total plasma calcium concentrations is vital for determining a therapeutic plan. Accurate evaluation of calcium status will provide assistance in the diagnosis of renal disease and seizures and allow for better evaluation of the health status of gravid female iguanas.

Full Text Available Defatted Brazil nut kernel flour, a rich source of high quality proteins, is presently being utilized in the formulation of animal feeds. One of the possible ways to improve its utilization for human consumption is through improvement in its functional properties. In the present study, changes in some of the functional properties of Brazil nut kernel globulin were evaluated after acetylation at 58.6, 66.2 and 75.3% levels. The solubility of acetylated globulin was improved above pH 6.0 but was reduced in the pH range of 3.0-4.0. Water and oil absorption capacity, as well as the viscosity increased with increase in the level of acetylation. Level of modification also influenced the emulsifying capacity: decreased at pH 3.0, but increased at pH 7.0 and 9.0. Highest emulsion activity (approximately 62.2% was observed at pH 3.0 followed by pH 9.0 and pH 7.0 and least (about 11.8% at pH 5.0. Emulsion stability also followed similar behavior as that of emulsion activity.Farinha desengordurada de amêndoa de castanha-do-Pará, fonte rica de proteína de alta qualidade, vem sendo, atualmente, aproveitada apenas na formulação de ração animal.

Full Text Available B-cell lymphoproliferative disorder (B-LPD is generally characterized by the proliferation of Epstein-Barr virus (EBV-infected B lymphocytes. We here report the development of EBV-negative B-LPD associated with EBV-reactivation following antithymocyte globulin (ATG therapy in a patient with aplastic anemia. The molecular autopsy study showed the sparse EBV-infected clonal T cells could be critically involved in the pathogenesis of EBV-negative oligoclonal B-LPD through cytokine amplification and escape from T-cell surveillances attributable to ATG-based immunosuppressive therapy, leading to an extremely rare B-cell-rich T-cell lymphoma. This report helps in elucidating the complex pathophysiology of intractable B-LPD refractory to rituximab.

Venous thromboembolic disease (VTD), deep venous thrombosis and pulmonary embolism, causes morbidity and mortality following total hip and total knee arthroplasties, while ileus complicates up to 4.0%. The clinical courses of 2,949 patients undergoing 3,364 consecutive primary and revision total hip and total knee arthroplasties, radical debridements, and reimplantations at one institution over a 2-year period were reviewed to examine the relationship between ileus and VTD. VTD prophylaxis consisted of aspirin and intermittent plantar pulse boots for all patients except those at high risk, who received parenteral chemical prophylaxis and boots. Ileus occurred in 62 patients (2.1%) and symptomatic DVT in 51 (1.7%). With ileus, the incidence of DVT was 8.1%: odds ratio 5.5 (P =.0036). Symptomatic pulmonary embolism occurred in 7 patients (0.24%); with ileus the incidence was 3.2%: odds ratio 19.6 (P =.0082). A significant increase was observed in rates of VTD with ileus. We recommend using parenteral chemical and mechanical prophylaxis in patients with ileus following total hip and total knee arthroplasties.

2013-07-01

Full Text Available Background: Epidemiological studies have shown that sex hormone-binding globulin (SHBG has a role in glucose homeostasis in both men and women. However, a prospective study on Japanese-American subjects concluded that SHBG was not a significant risk factor in either men or women, suggesting ethnic differences. We were not aware of any evaluation of SHBG in subjects of African ancestry. Objectives: We investigated the association between SHBG and insulin resistance in type 2 diabetic diabetic men in a hospital in Nigeria. Method: Forty-eight male subjects with type 2 diabetes and 20 non-diabetic male subjects were recruited in this cross-sectional hospital-based study by the convenient sampling method.Height and circumferences around the waist and hip were measured to the nearest 0.5 cm and the waist–hip ratio was calculated from this measurement. Weight was measured and body mass index was calculated. Fasting plasma glucose concentration was measured by the glucose oxidase method with a between-run coefficient of variation of 3%. Insulin and SHBG were measured by means of enzyme-linked immunosorbent assay (ELISA. Results: There was a statistically-significant difference between test results for the diabetic and non-diabetic patients. The mean SHBG concentration was higher in the non-diabetic group (42.2 nmol/L than the diabetic group (30.5 nmol/L. A significant inverse association between insulin resistance and SHBG was observed (r = 0.353, p < 0.015. Conclusion: This study supported earlier observations that a significant inverse correlation exists between SHBG and insulin resistance and provides evidence that the relationship may extend to type 2 diabetic men of African ancestry in Nigeria.

Loss of P53 Function in Colon Cancer Cells Results in Increased Phosphocholine and Total Choline

Directory of Open Access Journals (Sweden)

Noriko Mori

2004-10-01

Full Text Available Mutations in the p53 gene are the most frequently observed genetic lesions in human cancers. Human cancers that contain a p53 mutation are more aggressive, more apt to metastasize, and more often fatal. p53 controls numerous downstream targets that can influence various outcomes such as apoptosis, growth arrest, and DNA repair. Based on previous observations using 1H magnetic resonance spectroscopy (MRS, we have identified choline phospholipid metabolite intensities typical of increased malignancy. Here we have used 1H MRS to characterize the choline phospholipid metabolite levels of p53+/+ and p53−/– cells, and demonstrated that loss of p53 function results in increased phosphocholine and total choline. These data suggest that the increased malignancy of cancer cells resulting from loss of p53 may be mediated, in part, through the choline phospholipid pathway.

The total concentration of THC has been monitored in cannabis preparations sold in Dutch coffee shops since 1999. This annual monitoring was issued by the Ministry of Health after reports of increased potency. The level of the main psychoactive compound, Delta9-tetrahydrocannabinol (THC), is measured in marijuana and hashish. A comparison is made between imported and Dutch preparations, and between seasons. Samples of cannabis preparations from randomly selected coffee shops were analyzed using gas chromatography (GC-FID) for THC, CBD and CBN. In 2004, the average THC level of Dutch home-grown marijuana (Nederwiet) (20.4% THC) was significantly higher than that of imported marijuana (7.0% THC). Hashish derived from Dutch marijuana (Nederhasj) contained 39.3% THC in 2004, compared with 18.2% THC in imported hashish. The average THC percentage of Dutch marijuana, Dutch hashish and imported hashish was significantly higher than in previous years. It nearly doubled over 5 years. During this period, the THC percentage in imported marijuana remained unchanged. A higher price had to be paid for cannabis with higher levels of THC. Whether the increase in THC levels causes increased health risks for users can only be concluded when more data are available on adjusted patterns of use, abuse liability, bioavailability and levels of THC in the brain.

.This research aimed to evaluate the changes in the white blood cell count and some serum proteins of confined cattle (CC and grass cattle (GC. From the 120 blood samples collected, 60 were obtained from confined Nelore male bovines and 60 from animals with the same characteristics but managed extensively. Samples were obtained at the moment of slaughter. Parameters studied were the white blood cell count, serum albumin/globulin ratio and concentration of plasma fibrinogen. Descriptive statistics was used in the analysis of the data, and the averages, standard deviation and coefficient of variation calculated for all parameters evaluated. The comparisons between averages were made by non-parametric test. The grazing cattle showed higher levels of globulin and fibrinogen when compared to the confined ones (globulin: GC=3.29g dL-1±0.76; CC=2.99g dL-1±0.60 and Fibrinogen: GC=872mg dL-1±610; CC=633mg dL-1±319. The total number of white blood cells mL-1 was 7.64±2.15 in confined cattle and 7.72±1.84 in grazing cattle. There was no significant difference between this variable and differential white blood cell count as well as the total serum protein (g dL-1 from grazing cattle (6.10±0.53 and confined cattle (5.96±0.49. The level of albumin from confined cattle (3.01g dL-1± 0.43 and the A/G ratio (1.07±8.91 were greater when compared to the grazing bovines (2.82g dL-1±0.45 and (0.95±0.38 respectively. The higher serum levels of albumin found in confined herd suggest that they were subjected to a more adequate nutritional diet. The constant immunological challenge suffered by the GC could be responsible for the elevated serum levels of globulin and fibrinogen. These results showed that although feedlots present a stressful environment they did not show any blood alterations correlated to this fact.

Previously, we demonstrated that caffeine, a natural alkaloid, stimulates increased incidences of pulmonary hypertension syndrome (ascites) in broilers. The present study was designed to evaluate the ergogenic effects of caffeine on broiler performance and blood parameters. One-hundred-and-ninety-two Ross 308 male broiler chicks were randomly assigned at one d of age to 16 pens with 4 treatment groups. On d 3, the drinking water was supplemented with caffeine at levels of zero, 12.5, 25, and 50 mg/kg BW/day. Caffeine supplementation linearly improved (P caffeine (P > 0.05). On d 28, increasing caffeine supplementation caused linear reductions in plasma albumin, total protein, globulin, and triglyceride concentrations, and caffeine supplementation increased plasma uric acid concentrations (P caffeine did not consistently affect plasma albumin, globulin, triglyceride, total protein, uric acid, or urea concentrations (P > 0.05), whereas plasma glucose concentrations increased linearly with increasing caffeine levels (P caffeine (P > 0.05), but plasma T 3 concentrations were reduced by caffeine supplementation on d 28 and 42 (P caffeine supplementation on d 42. Skin temperature was not influenced by caffeine supplementation (P > 0.05). There was a negative correlation between thyroid hormone concentrations and BW on d 42 (P caffeine supplementation at the levels of 12.5 to 25 mg/kg BW/day increased BWG, decreased FCR and T 3 , and significantly altered blood biochemistry parameters. © 2016 Poultry Science Association Inc.

1995-01-01

Purpose: Recurrent acute cardiac allograft rejection is an important cause of repeat hospitalization and a major mode of mortality, particularly during the 6 months immediately following transplant. Total lymphoid irradiation (TLI) has been shown experimentally to induce a state of partial tolerance when administered prior to transplantation. Anecdotal reports of clinical experience have also suggested efficacy of TLI in treatment of recurrent cardiac rejection. The purpose of this study is to evaluate the safety and efficacy of TLI for treatment of early or recurrent heart transplant rejection. Materials and Methods: Between January 1990 and June 1992, 49 patients postallograft cardiac transplant were given courses of TLI for treatment of early or recurrent rejection after conventional therapy with Methylprednisolone, antithymocyte globulin, OKT3, and methotrexate. Two patients failed to complete their therapy and were not evaluated. Two other patients received a second TLI course, making a total of 49 courses delivered. Indications for TLI were early rejection (n = 5), recurrent rejection (n = 38), and recurrent rejection with vasculitis (n = 6). The dose goal of the TLI protocol was 8 Gy in 10 fractions given twice weekly. Three separate fields were used to encompass all major lymph node-bearing areas. The actual mean dose was 7 Gy (range 2.4-8.4 Gy), and the duration of treatment was 8 to 106 days. These variations were secondary to leukopenia or thrombocytopenia. Results: The mean posttransplant follow-up is 15 ± 1.2 months (maximum 27 months). Among patients initiating TLI within 1 month posttransplant (n = 15), the rejection frequency decreased from 1.83 episodes/patient/month pre-TLI to 0.13 episodes/patient/month post-TLI (p < 0.0001). For those who began TLI 1-3 months after transplant (n = 21), rejection decreased from 1.43 to 0.10 episodes/patient/month (p < 0.0001). When TLI was started more than 3 months posttransplant (n = 11), the pre-TLI and post

Smoking has many adverse health effects in infants and adults. The purpose of the study was to study the effect of passive cigarette smoking on oxidative and antioxidative status of plasma in passive smoker infants and their mothers and to compare with those of non-smokers. Subjects were randomly chosen from infants aged 8-26 weeks and their mothers aged 20-34 years. Passive smoker infants (n = 29) and their mothers (n = 29) were defined as having other family members who smoked six or more cigarettes per day continually for at least 8 weeks. Non-smokers were defined as infants (n = 30) and their mothers (n = 24) who had never been exposed to passive smoking. The antioxidative status of plasma were perused by measuring the total antioxidant capacity. Oxidative status was evaluated by predicating total peroxide level, oxidative stress index, protein oxidation and lipid peroxidation. Plasma concentrations of total antioxidant capacity were significantly lower in passive smoker infants and their mothers than non-passive smoker infants and their mothers. However, lipid peroxidation and oxidative stress index were remarkably higher in passive smoker infants and their mothers than those of non-passive smoker infants and their mothers. There were significant correlations between the oxidative and antioxidative parameters of the passive smoker infants and their mothers. Oxidants are increased and antioxidants are decreased in passive smoker infants and their mothers than those of non-smokers. Passive smoker infants and their mothers are exposed to potent oxidative stress.

Full Text Available The association between sex hormone-binding globulin (SHBG and arterial stiffness in women is not conclusive. In addition, obesity might also be involved in the relationship between SHBG and atherosclerosis. The aim of this study was to determine the relationship between SHBG and arterial stiffness in association with central obesity in women. This cross-sectional study included 381 women who participated in the health checkup programs in one hospital. The brachial-ankle pulse wave velocity (baPWV was measured as a marker for arterial stiffness. A negative correlation was observed between SHBG levels and baPWV (rho = −0.281. The relationship was significant even after adjusting for potential confounders (beta = −0.087 in fully adjusted model. After considering the interaction between central obesity and SHBG levels, the significant association was evident only in obese women (P for interaction = 0.025. Adjustment for a 10-year atherosclerotic cardiovascular disease (ASCVD risk scores, instead of each cardiovascular risk factor individually, did not affect the significance of the relationship between SHBG levels and baPWV. Serum levels of SHBG were negatively associated with arterial stiffness independent of cardiovascular risk factors or 10-year ASCVD risk scores in Korean women. The relationship may be potentiated by central obesity.

Despite being recommended as first-line immunosuppressive therapy in severe aplastic anemia (SAA), horse antithymocyte globulin (ATG) is still unavailable in many countries outside the USA. Rabbit ATG is more lymphocytoxic than horse ATG, and this might result in a higher incidence of severe infections and early mortality. This study was designed to identify the risk factors for early mortality and overall survival (OS) after rabbit ATG in patients with SAA. We retrospectively reviewed 185 patients with SAA who underwent rabbit ATG and cyclosporine. The incidence of death in 3 months following rabbit ATG therapy was 15.1% (28/185). Early mortality was mainly related to infectious complications, despite adequate antibiotic and/or antifungal treatment. Age > 35 years (odds ratio [OR] 5.06, P = 0.001) and baseline absolute neutrophil count (ANC) ≤ 0.1 × 10 9 /L (OR 7.64, P  35 years (OR 1.88, P = 0.03), baseline ANC ≤ 0.1 × 10 9 /L (OR 2.65, P < 0.001), and lack of response to rabbit ATG (OR 11.40, P < 0.001) were independently associated with mortality. Alternative strategies are needed for the treatment of SAA patients in countries were horse ATG is unavailable, particularly for those at high risk for early mortality after rabbit ATG due to a higher age and very low pre-treatment neutrophil count.

Rabbit corticosteroid-binding globulin (CBG) from the serum of pregnant and nonpregnant females differs in terms of charge microheterogeneity, and both forms were, therefore, radiolabeled and injected iv into 23- to 27-day pregnant rabbits (n = 6) to assess their biological half-lives and possible transfer to the fetal compartment. After an initially rapid distribution phase, the serum half-lives of both forms of [ 125 I]CBG were essentially identical (approximately 13 h) and did not vary at different gestational ages. There was also no difference in the transfer of either form of [ 125 I]CBG from maternal to fetal compartments in any of the animals studied. Moreover, [ 125 I]CBG showed no sign of degradation and retained its steroid-binding activity in fetal urine and amniotic fluid. Twenty-two hours after administration of [ 125 I]CBG to rabbits (n = 2) at 23 days gestation, its mean level in fetal urine (7 cpm/microliter) and amniotic fluid (2.5 cpm/microliter) was much higher than that in fetal blood (0.6 cpm/microliter). More importantly, the specific activities of [ 125 I]CBG in fetal urine and amniotic fluid were comparable to that in maternal serum, and approximately 2 orders of magnitude higher than that in fetal serum. Taken together, these results suggest that CBG in fetal urine and amniotic fluid is largely of maternal origin, and that maternal CBG crosses the fetal kidney preferentially

Sex-Hormone Binding Globulin (SHBG) may be associated to Pre-eclampsia (PE) and Fetal Growth Restriction (RCIU). To determine if maternal serum SHBG concentrations during the first and second trimesters are predictive biomarkers of Pre-eclampsia and RCIU. Prospective cohort study carried out in the Fetal Medicine Unit, Universidad de Chile Clinical Hospital between January, 2005 and December, 2006. Blood samples were obtained from unselected pregnant women during routine 11-14 week and 22-25 week ultrasound examinations, conforming two different study groups. Posteriorly, serum SHBG concentrations were determined in women who developed Pre-eclampsia, RCIU and their respective controls. Fifty five patients were included in the 11-14 weeks group. Nine women that developed PE, 10 that developed RCIU and 36 controls were selected from this group. There were no significant differences in SHBG levels between patients with PE, RCIU or controls (324.7 (26.6), 336.8 (33.9) and 377.5 (24.3) nmol/L, respectively). Fifty four women were included in the 22-25 weeks group. Eight women who developed Pre-eclampsia, 15 who developed RCIU and 31 controls were selected. Again, there were no significant differences in SHBG levels between patients with PE, RCIU or controls (345.5 (151.1), 383.8 (143.4) and 345.5 nmol/l (151.1), respectively). Maternal SHBG serum levels did not predict subsequent development of Pre-eclampsia and RCIU.

Total ankle arthroplasty (TAA) is an increasingly used, effective treatment for end-stage ankle arthritis. Although numerous studies have associated blood transfusion with complications following hip and knee arthroplasty, its effects following TAA are largely unknown. This study uses data from a large, nationally representative database to estimate the association between blood transfusion and inpatient complications and hospital costs following TAA. Using the Nationwide Inpatient Sample (NIS) database from 2004 to 2014, 25 412 patients who underwent TAA were identified, with 286 (1.1%) receiving a blood transfusion. Univariate analysis assessed patient and hospital factors associated with blood transfusion following TAA. Patients requiring blood transfusion were more likely to be female, African American, Medicare recipients, and treated in nonteaching hospitals. Average length of stay for patients following transfusion was 3.0 days longer, while average inpatient cost was increased by approximately 50%. Patients who received blood transfusion were significantly more likely to suffer from congestive heart failure, peripheral vascular disease, hypothyroidism, coagulation disorder, or anemia. Acute renal failure was significantly more common among patients receiving blood transfusion ( P < .001). Blood transfusions following TAA are infrequent and are associated with multiple medical comorbidities, increased complications, longer hospital stays, and increased overall cost.

Total knee replacement utilization in the United States more than doubled from 1999 to 2008. Although the reasons for this increase have not been examined rigorously, some have attributed the increase to population growth and the obesity epidemic. Our goal was to investigate whether the rapid increase in total knee replacement use over the past decade can be sufficiently attributed to changes in these two factors. We used data from the Nationwide Inpatient Sample to estimate changes in total knee replacement utilization rates from 1999 to 2008, stratified by age (eighteen to forty-four years, forty-five to sixty-four years, and sixty-five years or older). We obtained data on obesity prevalence and U.S. population growth from federal sources. We compared the rate of change in total knee replacement utilization with the rates of population growth and change in obesity prevalence from 1999 to 2008. In 2008, 615,050 total knee replacements were performed in the United States adult population, 134% more than in 1999. During the same time period, the overall population size increased by 11%. While the population of forty-five to sixty-four-year-olds grew by 29%, the number of total knee replacements in this age group more than tripled. The number of obese and non-obese individuals in the United States increased by 23% and 4%, respectively. Assuming unchanged indications for total knee replacement among obese and non-obese individuals with knee osteoarthritis over the last decade, these changes fail to account for the 134% growth in total knee replacement use. Population growth and obesity cannot fully explain the rapid expansion of total knee replacements in the last decade, suggesting that other factors must also be involved. The disproportionate increase in total knee replacements among younger patients may be a result of a growing number of knee injuries and expanding indications for the procedure.

Single-shot antithymocyte globulin (ATG) prior to reperfusion followed by tacrolimus (TAC), mycophenolate mofetil (MMF), and prednisolone (PRD) is an established induction therapy in simultaneous pancreas kidney transplant (SPK) recipients. We retrospectively analyzed 6-month data from 105 patients who received their first SPK. From January 1996 to December 2000, ATG-Fresenius was used. Since January 2001, Thymoglobulin has been administered. In the first group, 58 patients were treated with ATG-Fresenius (4-6 mg/kg body weight). In the second group, 47 patients received Thymoglobulin (1.5-2.5 mg/kg body weight). HLA-mismatch was comparable. After an observation period of 6 months, patients, kidney, and pancreas graft survival is 98.3%, 96.6%, and 93.1% in group I and 97.9%, 97.9%, and 85.1% in group II, respectively. In each group, one death with functioning graft (DWFG) was observed. Twenty (34.5%) acute rejection episodes (AR) were observed (18 patients) in group I. They were treated with steroids (n = 16) or steroids/OKT3 (n = 4). One kidney graft failure was observed due to rejection and one due to DWFG. Four pancreas grafts were lost (thrombosis, n = 2; AR, n = 1; DWFG, n = 1). In group II, 15 AR (31.9%) were seen in 12 patients and were treated with steroids (n = 12), steroids/ATG (n = 1), or steroids/OKT3 (n = 2). Seven pancreas (thrombosis, n = 5; rejection, n = 1; DWFG, n = 1) and one kidney (DWFG, n = 1) graft losses occurred. These data clearly establish that single-shot ATG prior to reperfusion, followed by TAC, MMF, and PRD results in a low incidence of AR (34.5% in group I and 31.9% in group II) after SPK. Only 6.9% (group I) and 6.4% (group II) of the patients received antibodies for rejection treatment.

Silencing of beta-carotene hydroxylase increases total carotenoid and beta-carotene levels in potato tubers

Directory of Open Access Journals (Sweden)

2007-03-01

Full Text Available Abstract Background Beta-carotene is the main dietary precursor of vitamin A. Potato tubers contain low levels of carotenoids, composed mainly of the xanthophylls lutein (in the beta-epsilon branch and violaxanthin (in the beta-beta branch. None of these carotenoids have provitamin A activity. We have previously shown that tuber-specific silencing of the first step in the epsilon-beta branch, LCY-e, redirects metabolic flux towards beta-beta carotenoids, increases total carotenoids up to 2.5-fold and beta-carotene up to 14-fold. Results In this work, we silenced the non-heme beta-carotene hydroxylases CHY1 and CHY2 in the tuber. Real Time RT-PCR measurements confirmed the tuber-specific silencing of both genes . CHY silenced tubers showed more dramatic changes in carotenoid content than LCY-e silenced tubers, with beta-carotene increasing up to 38-fold and total carotenoids up to 4.5-fold. These changes were accompanied by a decrease in the immediate product of beta-carotene hydroxylation, zeaxanthin, but not of the downstream xanthophylls, viola- and neoxanthin. Changes in endogenous gene expression were extensive and partially overlapping with those of LCY-e silenced tubers: CrtISO, LCY-b and ZEP were induced in both cases, indicating that they may respond to the balance between individual carotenoid species. Conclusion Together with epsilon-cyclization of lycopene, beta-carotene hydroxylation is another regulatory step in potato tuber carotenogenesis. The data are consistent with a prevalent role of CHY2, which is highly expressed in tubers, in the control of this step. Combination of different engineering strategies holds good promise for the manipulation of tuber carotenoid content.

The ability of simvastatin to mitigate the increases in risk factors for and the occurrence of cardiac disease after 10 Gy total body irradiation (TBI) was determined. This radiation dose is relevant to conditioning for stem cell transplantation and threats from radiological terrorism. Male rats received single dose TBI of 10 Gy. Age-matched, sham-irradiated rats served as controls. Lipid profile, heart and liver morphology and cardiac mechanical function were determined for up to 120 days after irradiation. TBI resulted in a sustained increase in total- and LDL-cholesterol (low-density lipoprotein-cholesterol), and triglycerides. Simvastatin (10 mg/kg body weight/day) administered continuously from 9 days after irradiation mitigated TBI-induced increases in total- and LDL-cholesterol and triglycerides, as well as liver injury. TBI resulted in cellular peri-arterial fibrosis, whereas control hearts had less collagen and fibrosis. Simvastatin mitigated these morphological injuries. TBI resulted in cardiac mechanical dysfunction. Simvastatin mitigated cardiac mechanical dysfunction 20-120 days following TBI. To determine whether simvastatin affects the ability of the heart to withstand stress after TBI, injury from myocardial ischemia/reperfusion was determined in vitro. TBI increased the severity of an induced myocardial infarction at 20 and 80 days after irradiation. Simvastatin mitigated the severity of this myocardial infarction at 20 and 80 days following TBI. It is concluded simvastatin mitigated the increases in risk factors for cardiac disease and the extent of cardiac disease following TBI. This statin may be developed as a medical countermeasure for the mitigation of radiation-induced cardiac disease.

Rabies is an acute encephalitis that is nearly always fatal. It is caused by infection with viruses of the genus Lyssavirus, the most common of which is Rabies lyssavirus. The Council of State and Territorial Epidemiologists (CSTE) defines a confirmed human rabies case as an illness compatible with rabies that meets at least one of five different laboratory criteria.* Four of these criteria do not depend on the patient's rabies vaccination status; however, the remaining criterion, "identification of Lyssavirus-specific antibody (i.e. by indirect fluorescent antibody…test or complete [Rabies lyssavirus] neutralization at 1:5 dilution) in the serum," is only considered diagnostic in unvaccinated patients. Lyssavirus-specific antibodies include Rabies lyssavirus-specific binding immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies and Rabies lyssavirus neutralizing antibodies (RLNAs). This report describes six patients who were tested for rabies by CDC and who met CSTE criteria for confirmed human rabies because they had illnesses compatible with rabies, had not been vaccinated for rabies, and were found to have serum RLNAs (with complete Rabies lyssavirus neutralization at a serum dilution of 1:5). An additional four patients are described who were tested for rabies by CDC who were found to have serum RLNAs (with incomplete Rabies lyssavirus neutralization at a serum dilution of 1:5) despite having not been vaccinated for rabies. None of these 10 patients received a rabies diagnosis; rather, they were considered to have been passively immunized against rabies through recent receipt of intravenous immune globulin (IVIG). Serum RLNA test results should be interpreted with caution in patients who have not been vaccinated against rabies but who have recently received IVIG.

This paper is a report on the analysis of equatorial electron content, TEC, during magnetic storms. Storms between 1969 and 1972 have been examined as part of an on-going study of TEC morphology during magnetically disturbed days. The published magnetic Ksup(p) indices and TEC data from the Legon abservatory have been employed. The general picture arising from the analysis is that the total electron content of the ionosphere is significantly enhanced during magnetic storms. (author)

Antithymocyte globulin rabbit (r-ATG) has been used for the treatment and prevention of acute rejection in renal transplant recipients (RTR). Current manufacturer recommendations for r-ATG dictate the need for administration through a high-flow vein (central line). Previous studies have shown peripheral administration of r-ATG to be safe; however, these studies suggest the co-administration of heparin and hydrocortisone and did not compare the infusion-site reaction rates to a control group. A retrospective analysis was conducted of adult RTR receiving r-ATG or basiliximab between January 2004 and October 2006. Each agent was administered through a dedicated peripheral line. The primary endpoint was the incidence of infusion-site reactions. Other endpoints included the need to replace the intravenous catheter and the incidence of systemic thrombosis within 1 month of transplantation. During the study period, 152 peripheral infusions of r-ATG and 92 peripheral infusions of basiliximab were administered. No difference in infusion-site reactions was noted between the groups. There was also no difference either in the need for peripheral line replacement or the rates of systemic thrombosis. Peripheral administration of r-ATG is safe and can be infused without concomitant heparin and hydrocortisone. This method of r-ATG infusion was shown to be as safe as peripherally administered basiliximab.

The United States Food and Drug Administration (FDA) has approved unconjugated monoclonal antibodies (MAbs) for immunotherapy (IT) of B-cell lymphoma, breast cancer and acute myeloid leukemia. More recently, approval has been given for conjugated ZevalinTM ((90)yttrium ibritumomab tiuxetan, IDEC-Y2B8, Biogen Idec, Cambridge, MA) and BexxarTM ((131)I-tositumomab, Corixa, Corp., Seattle, WA and GlaxoSmithKline, Philadelphia, PA) anti-CD20 MAbs for use in radioimmunotherapy (RIT) of non-Hodgkin's lymphoma (NHL), thus redefining the standard care of cancer patients. Because of, and despite a lack of basis for concern about allergic reactions due to human antibody responses to these foreign proteins, assays were developed to determine HAGA (human anti-globulin antibody) levels that developed in patient sera following treatment with MAbs. Strategies were also devised to ''humanize'' MAbs and to temporarily block patient immune function with drugs in order to decrease the seroconversion rates, with considerable success. On the other hand, a survival advantage has been observed in some patients who developed a HAGA following treatment. This correlates with development of an anti-idiotype antibody cascade directed toward the MAbs used to treat these patients. What follows is a selective review of HAGA and its effect on cancer treatment over the past 2 decades.

Species-specific antibodies (Ab) for the measurement of immunoglobulins (Ig) are valuable tools for determining the humoral immune status of threatened and endangered wildlife species such as dugongs. However, no studies have reported antibody reagents against dugong immunoglobulin. The object of this study was to develop an Ab with specificity for dugong IgG and apply this tool to survey total IgG levels in plasma samples from a live wild population of dugongs in southern Queensland, Australia. Dugong IgG was isolated from plasma by protein A/G column chromatography and a polyclonal antiserum was successfully raised against the dugong IgG through immunization of mice. The anti-dugong antiserum was reactive with dugong serum but not immunoglobulin from other species such as rats and humans. When tested against a panel of dugong plasma samples, relative IgG levels from dugongs (n = 116) showed biologically relevant relationships with pregnancy status and a principal component of Body Mass Index (BMI)/globulin/fecal glucocorticosteroid (chronic stress) levels combined, which together accounted for 9.2% of the variation in total Ig levels. Together these data suggest that dugongs show variation in total IgG and that this correlates with some physiological parameters of dugong health. Copyright © 2018 Elsevier B.V. All rights reserved.

Cryptorchism is one of the few well-described risk factors for testicular cancer. It has been suggested that both conditions are related to increased in utero estrogen exposure. The evidence supporting the "estrogen hypothesis" has been inconsistent, however. An alternative hypothesis suggests that higher in utero androgen exposure may protect against the development of cryptorchism and testicular cancer. In order to examine both hypotheses, we studied maternal hormone levels in two populations at diverse risks of testicular cancer; Black Americans (low-risk) and White Americans (high-risk). The study population of 200 mothers of cryptorchid sons and 200 mothers of noncryptorchid sons was nested within the Collaborative Perinatal Project, a cohort study of pregnant women and their children. Third trimester serum levels of estradiol (total, free, bioavailable), estriol, testosterone (total, free, bioavailable), sex hormone-binding globulin, alpha-fetoprotein, and the ratios of estradiols to testosterones were compared between the case and control mothers. The results found no significant differences in the levels of testosterone (total, free, bioavailable), alpha-fetoprotein, sex hormone-binding globulin, or in the ratios of estrogens to androgens. Total estradiol, however, was significantly lower in the cases versus the controls (P = 0.03) among all mothers and, separately, among White mothers (P = 0.05). Similarly, estriol was significantly lower among all cases (P = 0.05) and among White cases (P = 0.05). These results do not support either the estrogen or the androgen hypothesis. Rather, lower estrogens in case mothers may indicate that a placental defect increases the risk of cryptorchism and, possibly, testicular cancer.

We previously demonstrated that a nonmyeloablative preparative regimen can induce mixed chimerism and renal allograft tolerance between MHC-disparate non-human primates. The basic regimen includes anti-thymocyte globulin (ATG), total body irradiation (TBI, 300 cGy), thymic irradiation (TI, 700 cGy), splenectomy, donor bone marrow (DBM) infusion, and posttransplant cyclosporine therapy (CYA, discontinued after 4 weeks). To evaluate the importance and to minimize the toxicity of irradiation, kidney allografts were transplanted with various manipulations of the irradiation protocol. Monkeys treated with the basic protocol without TBI and TI did not develop chimerism or long-term allograft survival. In monkeys treated with the full protocol, all six monkeys treated with two fractionated dose of 150 cGy developed chimerism and five monkeys appeared tolerant. In contrast, only two of the four monkeys treated with fractionated doses of 125 cGy developed chimerism and only one monkey survived long term. The degree of lymphocyte depletion in all recipients was proportional to the TBI dose. The fractionated TBI regimen of 150 cGy appears to be the most consistently effective regimen for establishing donor bone marrow cell engraftment and allograft tolerance. (author)

The total nucleated cell dosage of umbilical cord blood (UCB) is an important factor in determining successful allogeneic hematopoietic stem cell transplantation after a minimum human leukocyte antigen donor-recipient match. The northern South American population is in need of a new-generation cord blood bank that cryopreserves only units with high total nucleated cell content, thereby increasing the likelihood of use. Colombia set up a public cord blood bank in 2014; and, as a result of its research for improving high total nucleated cell content, a new strategy for UCB collection was developed. Data from 2933 collected and 759 cryopreserved cord blood units between 2014 and 2015 were analyzed. The correlation of donor and collection variables with cellularity was evaluated. Moreover, blood volume, cell content, CD34+ count, clonogenic capacity, and microbial contamination were assessed comparing the new method, which combines in utero and ex utero techniques, with the conventional strategies. Multivariate analysis confirmed a correlation between neonatal birth weight and cell content. The new collection method increased total nucleated cell content in approximately 26% and did not alter pre-cryopreservation and post-thaw cell recovery, viability, or clonogenic ability. Furthermore, it showed a remarkably low microbial contamination rate (1.2%). The strategy for UCB collection developed at the first Colombian public cord blood bank increases total nucleated cell content and does not affect unit quality. The existence of this bank is a remarkable breakthrough for Latin-American patients in need of this kind of transplantation. © 2017 The Authors Transfusion published by Wiley Periodicals, Inc. on behalf of AABB.

Genetic improvement of soybean seed proteins by γ-ray irradiation

International Nuclear Information System (INIS)

Kitamura, Keisuke

1998-01-01

Although soybeans have the highest protein content among seed crops, the protein quality is poor due to the low content of the sulfur-containing amino acids, cysteine and methionine. Soybean 7S globulin and 11S globulin are the two major protein components, accounting for about 70% of the total seed protein. The 11S globulin contains three to four times more methionine and cysteine per unit protein than that of the 7S globulin. Furthermore, the two globulins show considerable differences in food processing properties such as gel-making ability and emulsifying capacity. The 7S globulin is composed of three kinds of polypeptides, designated as α, α' and β subunits. A variety of soybean cv. Keburi, which lacks α' subunit was identified in a germplasm collection. An induced mutant line which lacks both α and α' subunits, was recently identified in the progeny of γ-ray-irradiated seeds from a line lacking α' subunit. On the other hand, the 11S globulin is composed of the A 1a B 2 , A 1b B 1b , A 2 B 1a , A 3 B 4 and A 4 A 5 B 3 subunits. It has become possible to breed soybeans with markedly modified protein composition from extremely high to extremely low 7S : 11S ratios using mutant genes for the subunits of the two globulins. Lipoxygenase catalyzes the hydroperoxydation of unsaturated fatty acids and polyunsaturated lipids. Soybean seeds contain three lipoxygenase isozymes, called L-1, L-2 and L-3, which are responsible for the generation of grassy-beany and bitter tastes, limiting the use of whole soybeans and soy proteins in certain food products. In the early 1980s, three types of spontaneous mutant soybean varieties lacking L-1, L-2 or L-3 were detected. Soybean cultivars having the lipoxygenase-null traits could become economically valuable for the manufacture of soy products such as soy milk due to their low levels of beany taste and their enhanced storage stability.

Plasma very low-density lipoprotein (VLDL) can be used to select for low body fat or abdominal fat (AF) in broilers, but its correlation with AF is limited. We investigated whether any other biochemical indicator can be used in combination with VLDL for a better selective effect. Nineteen plasma biochemical indicators were measured in male chickens from the Northeast Agricultural University broiler lines divergently selected for AF content (NEAUHLF) in the fed state at 46 and 48 d of age. The average concentration of every parameter for the 2 d was used for statistical analysis. Levels of these 19 plasma biochemical parameters were compared between the lean and fat lines. The phenotypic correlations between these plasma biochemical indicators and AF traits were analyzed. Then, multiple linear regression models were constructed to select the best model used for selecting against AF content. and the heritabilities of plasma indicators contained in the best models were estimated. The results showed that 11 plasma biochemical indicators (triglycerides, total bile acid, total protein, globulin, albumin/globulin, aspartate transaminase, alanine transaminase, gamma-glutamyl transpeptidase, uric acid, creatinine, and VLDL) differed significantly between the lean and fat lines (P linear regression models based on albumin/globulin, VLDL, triglycerides, globulin, total bile acid, and uric acid, had higher R2 (0.73) than the model based only on VLDL (0.21). The plasma parameters included in the best models had moderate heritability estimates (0.21 ≤ h2 ≤ 0.43). These results indicate that these multiple linear regression models can be used to select for lean broiler chickens. © 2017 Poultry Science Association Inc.

Full Text Available Effects of higher levels of chromium alone and in combination with copper were investigated in broiler chicks divided into seven equal groups viz. A, B, C, D, E, F and G. Group G served as control receiving no treatment. Groups A, B and F received chromium chloride at the rate of 2 g/kg and nicotinic acid 150 mg/kg feed while C, D and F received chromium chloride 8 g/kg and nicotinic acid 150mg/kg. Broilers of groups A and C received copper sulfate at the rate of 200 mg/kg while groups Band D 400 mg/kg feed. Haematological parameters studied revealed non-significant difference between treatment groups and control in haemoglobin concentration and total erythrocyte counts. However, only at 4th week, lower PCV was observed in birds fed higher levels of chromium chloride alone. Increase in TLC was observed in birds fed low chromium alone or' with low levels of copper. Results of serum proteins including total protein, albumin and globulin during first three weeks showed significantly or relatively lower values in treatment groups than control. Serum globulins generally revealed non-significant difference between treatment groups and control.

Antithymocyte globulin (ATG) is used as induction therapy after cardiac transplant for enhancing immunosuppression and delaying the initiation of nephrotoxic drugs. It is unknown if ATG induction is associated with decreased coronary plaque progression by intravascular ultrasound (IVUS). Patients transplanted between March 2010 and December 2012 with baseline and 1-year IVUS were included. All patients transplanted were included in a secondary analysis. Change in plaque progression was measured in a blinded fashion on matched coronary segments and contrasted between patients induced with ATG and those who were not. One hundred and three patients were included in IVUS arms. Mean age at transplant was 55.8 ± 12.6 years, and 33.0% were female. Patients induced with ATG were more sensitized (54.3% versus 14.3%). Plaque progression was attenuated in patients who received ATG by changes in maximal intimal area (1.0 ± 1.2 versus 2.3 ± 2.6 mm(2); P = 0.001), maximal percent stenosis (6.3 ± 7.9 versus 12.8 ± 12.3%; = 0.003), maximal intimal thickness (0.2 ± 0.2 versus 0.3 ± 0.3 mm; P = 0.035), and plaque volume (0.5 ± 0.7 versus 1.0 ± 1.3 mm(3)/mm; P = 0.016). Rapid plaque progression by maximal percent stenosis (≥ 20%) occurred less frequently in the ATG arm (4.3% versus 26.3; P = 0.003). Survival (P = 0.242) and any treated rejection (P = 0.166) were not statistically different between groups. Patients receiving ATG had a higher rate of first-year infection (P = 0.003), perhaps related to increased intravenous antibiotic use immediately postoperatively, and a trend toward more biopsy-proven rejection (P = 0.073). Induction therapy with ATG is associated with reduced first-year coronary plaque progression as assessed by IVUS, despite an increased prevalence of sensitized patients with a trend toward more rejection. © 2016 American Heart Association, Inc.

Blood total antioxidant capacity (TAC) has become a key bio-marker for animal health. Forest-grazing cattle are known to forage various native plants that have high TAC. This study evaluated differences of plasma TAC between forest-grazing (FG) and pasture-grazing cattle (PG). Experiment 1 monitored the plasma TAC levels of 32 Japanese Black cattle. The level in PG did not change throughout the grazing period. However, that in FG, which increased from summer, was significantly higher than that in PG through fall (P trees consumed by FG were higher than those in pasture grasses. Results of this study show that plasma TAC of grazing Japanese Black cattle in forestland increase from summer through fall. © 2013 Japanese Society of Animal Science.

Gastrectomy induces osteopenia. We examined the effects of feeding a diet containing soluble dietary fiber, guar gum hydrolysate (GGH, 50 g/kg diet), on intestinal calcium absorption and bone mineralization in totally gastrectomized (Roux-en-Y esophagojejunostomy) rats by comparing them with those in two control groups (laparotomized and bypassed rats). In the bypassed rats, chyme bypassed the duodenum and upper jejunum without gastrectomy. In a second separate experiment, we compared calcium absorption and bone mineralization in the gastrectomized rats fed diets containing soluble and insoluble calcium salts and in bypassed rats fed insoluble calcium. In Experiment 1, apparent absorption of calcium supplied as a water-insoluble salt was more than 50% lower in gastrectomized rats than in the intact (laparotomized) or bypassed rats 3 wk after the start of feeding the test diets (P Calcium absorption was higher (P Experiment 2, absorption of soluble calcium in the gastrectomized rats did not differ from the absorption of calcium from calcium carbonate by bypassed rats. The soluble calcium pool in the cecal contents was significantly lower in gastrectomized rats (Experiment 1) than in intact or bypassed control rats, and was higher (P calcium absorption correlated most closely (r = 0.787, P calcium content was significantly lower in gastrectomized rats fed insoluble calcium than in bypassed rats fed the same diet, but was partially restored in the rats fed soluble calcium (Experiment 2). Bone calcium was not increased by feeding GGH in gastrectomized rats (Experiment 1). We conclude that the severely diminished calcium absorption following total gastrectomy is totally due to a decrease in calcium solubilization, and feeding GGH partially restores calcium absorption. The decrease in bone calcium that occurs as a result of gastrectomy is mainly due to diminished intestinal calcium absorption.

Wheat is a staple food grain in India after rice and occupies number one position in the world. The wheat crop not only gives food grains but also gives fodder for animals. Among many preservation methods irradiation is a current technique used to overcome infestation, contamination and spoilage of stored grains. The present study is aimed to check the changes in composition of irradiated wheat flour. Wheat flour was exposed to five different irradiation doses (0.25 KGy, 0.5KGy, 1KGy, 5KGy and 10 KGy) by using 60 Co gamma-irradiation chamber. Irradiated flour was stored in air sealed polyethylene pouch and plastic container at room temperature for different time intervals (0 th day, 1 month and 3 months). The stored flour was checked for total antioxidant activity by phosphomolybdate method and total carbohydrates concentration by phenol-sulphuric acid method. On 0 th day total antioxidant activity and total carbohydrate concentration was found to be increased at 0.5KGy (0.113 mg/ml and 0.045 mg/ml respectively) when compared to control (0.79 mg/ml and 39.5 mg/ml). Similarly for 1 month stored samples of air sealed polyethylene pouch total antioxidant activity and total carbohydrate concentration was observed to be increased at 0.5KGy (0.117 mg/ml and 0.045mg/ml respectively) when compared to control (0.096 mg/ml and 0.035 mg/ml). But in case of stored samples of plastic container total antioxidant activity increased at 0.25KGy (0.060 mg/ml) and total carbohydrate increased at 5KGy (0.051 mg/ml). Increased and decreased values were found in both factors for 3 months stored samples of air sealed polyethylene pouch and plastic container. Total antioxidant activity increased at 5KGy (0.072 mg/ml) for polyethylene bag samples and at 0.5KGy (0.137 mg/ml) for plastic container sample. Same way total carbohydrate concentration increased at 0.25KGy (0.046 mg/ml) and at 1KGy (0.045 mg/ml) respectively. This increase is due to affects of γ-irradiation on biomolecules by

The strain on clinic and surgeon resources resulting from a rise in demand for total knee replacement (TKR) requires reconsideration of when and how often patients need to be seen for follow-up. Surgeons will otherwise require increased paramedical staff or need to limit the number of TKRs they undertake. We reviewed the outcome data of 16 414 primary TKRs undertaken at our centre to determine the time to re-operation for any reason and for specific failure mechanisms. Peak risk years for failure were determined by comparing the conditional probability of failure, the number of failures divided by the total number of TKRs cases, for each year. The median times to failure for the most common failure mechanisms were 4.9 years (interquartile range (IQR) 1.7 to 10.7) for femoral and tibial loosening, 1.9 years (IQR 0.8 to 3.9) for infection, 3.1 years (IQR 1.6 to 5.5) for tibial collapse and 5.6 years (IQR 3.4 to 9.3) for instability. The median time to failure for all revisions was 3.3 years (IQR 1.2 to 8.5), with an overall revision rate of 1.7% (n = 282). Results from our patient population suggest that patients be seen for follow-up at six months, one year, three years, eight years, 12 years, and every five years thereafter. Patients with higher pain in the early post-operative period or high body mass index (≥ 41 kg/m(2)) should be monitored more closely.

Analysis of interrelationship between the protein fractions content and blood serum immunoglobulins with irradiation of atomic industry enterprises workers

989 workers of atomic industry at the age from 35 to 78 years old subjected to the general external gamma radiation and incorporation of plutonium 239 in a wide range of doses about 17-40 years ago have been examined for the protein indices with the radiation effect bearing in mind nine non-radiation factors. The step-by-step regression analysis revealed a positive linear link for the total protein level, absolute content of alpha-1-globulins with the total dose of external gamma radiation. Increasing of serum proteins entropy, correlated with external radiation by protein shifts effect, had not coincided with its age increasing. The influence of plutonium-239 incorporation on the examined protein parameters was not found

alpha 2u-Globulin (alpha 2u) has been shown to accumulate in the kidneys of male rats treated with 2,2,4-trimethylpentane (TMP). 2,4,4-Trimethyl-2-pentanol (TMP-2-OH), a metabolite of TMP, is found reversibly bound to alpha 2u isolated from the kidneys of these treated rats. The objectives of the following study were to characterize the ability of [3H]TMP-2-OH to bind to alpha 2u in vitro and to determine whether other compounds that cause this protein to accumulate have the same binding characteristics. Although compounds that have been shown to cause the accumulation of alpha 2u in male rat kidneys compete in vitro with [3H]TMP-2-OH for binding to alpha 2u, they do so to varying degrees. The binding affinity (Kd) of the [3H]TMP-2-OH-alpha 2u complex was calculated to be on the order of 10(-7) M. The inhibition constant values (Ki) determined for d-limonene, 1,4-dichlorobenzene, and 2,5-dichlorophenol were all in the range 10(-4) M, whereas the Ki values for isophorone, 2,4,4- or 2,2,4-trimethyl-1-pentanol, and d-limonene oxide were determined to be in the range 10(-6) and 10(-7) M, respectively. TMP and 2,4,4- and 2,2,4-trimethylpentanoic acid did not compete for binding. This suggests that other factors, besides binding, are involved in the accumulation of alpha 2u. In this study the ability of a chemical to bind to alpha 2u was used as a measure of biological activity to assess structure-activity relationships among the chemicals tested and known to cause the accumulation of alpha 2u. The results so far suggest that binding is dependent on both hydrophobic interactions and hydrogen bonding

Apoptotic effects of antilymphocyte globulins on human pro-inflammatory CD4+CD28- T-cells.

Directory of Open Access Journals (Sweden)

Full Text Available BACKGROUND: Pro-inflammatory, cytotoxic CD4(+CD28(- T-cells with known defects in apoptosis have been investigated as markers of premature immuno-senescence in various immune-mediated diseases. In this study we evaluated the influence of polyclonal antilymphocyte globulins (ATG-Fresenius, ATG-F on CD4(+CD28(- T-cells in vivo and in vitro. PRINCIPAL FINDINGS: Surface and intracellular three colour fluorescence activated cell sorting analyses of peripheral blood mononuclear cells from 16 consecutive transplant recipients and short-term cell lines were performed. In vivo, peripheral levels of CD3(+CD4(+CD28(- T-cells decreased from 3.7 ± 7.1% before to 0 ± 0% six hours after ATG-F application (P = 0.043 in 5 ATG-F treated but not in 11 control patients (2.9 ± 2.9% vs. 3.9 ± 3.0%. In vitro, ATG-F induced apoptosis even in CD4(+CD28(- T-cells, which was 4.3-times higher than in CD4(+CD28(+ T-cells. ATG-F evoked apoptosis was partially reversed by the broad-spectrum caspase inhibitor benzyloxycarbonyl (Cbz-Val-Ala-Asp(OMe-fluoromethylketone (zVAD-fmk and prednisolon-21-hydrogensuccinate. ATG-F triggered CD25 expression and production of pro-inflammatory cytokines, and induced down-regulation of the type 1 chemokine receptors CXCR-3, CCR-5, CX3CR-1 and the central memory adhesion molecule CD62L predominately in CD4(+CD28(- T-cells. CONCLUSION: In summary, in vivo depletion of peripheral CD3(+CD4(+CD28(- T-cells by ATG-F in transplant recipients was paralleled in vitro by ATG-F induced apoptosis. CD25 expression and chemokine receptor down-regulation in CD4(+CD28(- T-cells only partly explain the underlying mechanism.

Insulin-like growth factor-I (IGF-I) stimulates ovarian androgen production. Insulin-like growth factor binding protein-1 (IGFBP-1) inhibits IGF actions in vitro. To investigate the effect of oral contraceptive (OC) pills, given for 3 months, on serum gonadotropin, androgen, IGF-I, and IGFBP-1 concentrations, and glucose tolerance in seven women with polycystic ovarian disease (PCOD) and in five healthy control subjects. Seven women with PCOD and five healthy control subjects. An oral glucose tolerance test (OGTT) was performed before and after treatment with OC. After treatment with OC, serum luteinizing hormone, androstenedione, and free testosterone levels decreased, and sex hormone-binding globulin concentration increased in the women with PCOD as well as in the control subjects. The cumulative response of serum insulin to OGTT was larger in the women with PCOD than in the control subjects both before and after treatment. Serum IGF-I concentration, which was unchanged during OGTT, decreased from basal level of 326 +/- 70 micrograms/L to 199 +/- 28 micrograms/L after treatment with OC in the women with PCOD, whereas no change was found in the control subjects (from 235 +/- 11 micrograms/L to 226 +/- 11 micrograms/L). Treatment with OC caused an increase of the mean basal IGFBP-1 concentration from 24 +/- 7 micrograms/L to 73 +/- 14 micrograms/L in the women with PCOD. This increase was constant during the OGTT. In the control subjects, treatment with OC did not result in any significant change in IGFBP-1 concentrations (from 44 +/- 11 micrograms/L to 61 +/- 9 micrograms/L). The combination of decreased total IGF-I concentration and increased IGFBP-1 concentration induced by OC may decrease ovarian androgen production in PCOD.

The purpose of this study was to establish reference intervals of the protein electrophoretic fractions and the acute-phase proteins hemoglobin binding protein (as determined by the haptoglobin assay) and C-reactive protein (CRP) and assess any possible correlations between varying age class, sex, location (Illinois or Michigan), year, or presence of snake fungal disease (SFD). Banked plasma samples were assayed from 130 eastern massasaugas from 2009 to 2014 in Illinois and Michigan. Snakes from Michigan had higher total protein (mean: 5.50 g/dl), albumin/globulin ratio (0.42), albumin (1.59 g/dl), and gamma globulins (0.55 g/dl) than from snakes in Illinois (4.72 g/dl, 0.29, 1.03 g/dl, 0.38 g/dl, respectively). Snakes in Illinois (22.19 g/ml) had higher CRP than snakes in Michigan (10.89 mg/ml). Adults had higher gamma globulins (0.47 g/dl) than juveniles (0.28 g/dl). Males had higher alpha-2 globulins (0.98 g/dl) and CRP (21.4 mg/ml) than females (0.85, 11.6, respectively). There were no significant differences in absolute plasma proteins in SFD-positive snakes, but the percentage of gamma globulins was significantly higher in positive snakes. Future research in this area can now build on this data to determine changes in population health over time or due to specific environmental or disease threats.

The jojoba, Simmondsia chinensis, is a characteristic desert plant native to the Sonoran desert. The jojoba meal after oil extraction is rich in protein. The major jojoba proteins were albumins (79%) and globulins (21%), which have similar amino acid compositions and also showed a labile thrombin-inhibitory activity. SDS-PAGE showed two major proteins at 50 kDa and 25 kDa both in the albumins and in the globulins. The 25 kDa protein has trypsin- and chymotrypsin-inhibitory activities. In vitro digestibility of the globulins and albumins resembled that of casein and soybean protein concentrates and was increased after heat treatment. The increased digestibility achieved by boiling may be attributed to inactivation of the protease inhibitors and denaturation of proteins.

Full Text Available This work focuses on the study of the effect of exercise on biochemical and hormonal rates in young men of different body types. The study involved 40 students of 17-23 years old, who were divided into 4 groups. Each group included 10 people with different somatotype (chest, muscular and the level of physical fitness (don't go in for sports, sportsmen. It was specified that there are some different changes (depending on somatotype in the blood of students who aren't involved in sports. The changes are caused by increasing the amount of total protein, soluble triglycerides, β-globulin, hormone of growth against minor changes in the content of the aqueous phase and the reduction of glucose, cholesterol, α-and γ-globulin, insulin. Slight exercise stress in sportsmen with breast somatotype insignificantly changed biochemical indicators of blood, muscular - there was almost no effect in biochemical indicators of blood; but it led to changes in hormonal status of sportsmen.

Nowadays, increasing attention has been given to the roles of free radicals generated through oxidative stres. The present study aims to evaluate the antioxidative role lycopene extracted from tomato processing wastes or pomace against hazards induced by gamma irradiation. Male rats were adminstered lycopene by a daily intragastric gavage(0.24mg/rat/day) or supplemented in a standard casein diet (6.5 Gy) of whole body gamma radiation. Lipid peroxides (MDA) reduced ghutathione (GSH) and superoxide dismutase activity (SOD) were determined in liver homogenate, as well as serum levels of alanine aminotransferase (ALT). asparate aminotransferase (AST), toral protein, albumin, globulin and A/G ratio were investigated 2 and 13 days post irradiation and/or lycopene administration. The results revealed that exposure to ionizing radiation resulted in significant elevation in MDA, ALT,AST, albumin levels and A/G ratio. Meanwhile, radiation exposure caused significant reduction in weight gain, SOD activity, GSH, total protein and globulin levels

Full Text Available Genome-wide association studies (GWAS have successfully identified common genetic variants that contribute to breast cancer risk. Discovering additional variants has become difficult, as power to detect variants of weaker effect with present sample sizes is limited. An alternative approach is to look for variants associated with quantitative traits that in turn affect disease risk. As exposure to high circulating estradiol and testosterone, and low sex hormone-binding globulin (SHBG levels is implicated in breast cancer etiology, we conducted GWAS analyses of plasma estradiol, testosterone, and SHBG to identify new susceptibility alleles. Cancer Genetic Markers of Susceptibility (CGEMS data from the Nurses' Health Study (NHS, and Sisters in Breast Cancer Screening data were used to carry out primary meta-analyses among ~1600 postmenopausal women who were not taking postmenopausal hormones at blood draw. We observed a genome-wide significant association between SHBG levels and rs727428 (joint β = -0.126; joint P = 2.09 × 10(-16, downstream of the SHBG gene. No genome-wide significant associations were observed with estradiol or testosterone levels. Among variants that were suggestively associated with estradiol (P<10(-5, several were located at the CYP19A1 gene locus. Overall results were similar in secondary meta-analyses that included ~900 NHS current postmenopausal hormone users. No variant associated with estradiol, testosterone, or SHBG at P<10(-5 was associated with postmenopausal breast cancer risk among CGEMS participants. Our results suggest that the small magnitude of difference in hormone levels associated with common genetic variants is likely insufficient to detectably contribute to breast cancer risk.

Rabbit antithymocyte globulin (rATG; thymoglobulin, Genzyme) in combination with cyclosporine, as first-line immunosuppressive therapy, was evaluated prospectively in a multicenter, European, phase 2 pilot study, in 35 patients with aplastic anemia. Results were compared with 105 age- and disease severity-matched patients from the European Blood and Marrow Transplant registry, treated with horse ATG (hATG; lymphoglobulin) and cyclosporine. The primary end point was response at 6 months. At 3 months, no patients had achieved a complete response to rATG. Partial response occurred in 11 (34%). At 6 months, complete response rate was 3% and partial response rate 37%. There were 10 deaths after rATG (28.5%) and 1 after subsequent HSCT. Infections were the main cause of death in 9 of 10 patients. The best response rate was 60% for rATG and 67% for hATG. For rATG, overall survival at 2 years was 68%, compared with 86% for hATG (P = .009). Transplant-free survival was 52% for rATG and 76% for hATG (P = .002). On multivariate analysis, rATG (hazard ratio = 3.9, P = .003) and age more than 37 years (hazard ratio = 4.7, P = .0008) were independent adverse risk factors for survival. This study was registered at www.clinicaltrials.gov as NCT00471848.

The United States Food and Drugs Administration (FDA) has approved unconjugated monoclonal antibodies (MAbs) for immunotherapy (IT) of B-cell lymphoma, breast cancer and acute myeloid leukemia. More recently, approval has been given for conjugated ZevalinTM ({sup 9}0yttrium ibritumomab tiuxetan, IDEC-Y2B8, Biogen Idec, Cambridge, MA) and BexxarTM ({sup 1}31I-tositumomab, Corixa, Corp., Seattle, WA and GlaxoSmithKline, Philadelphia, PA) antiCD20 MAns for use in radioimmunotherapy (RIT) of non-Hodgikin's lymphoma (NHL), thus redefining the standard care of cancer patients. Because of, and despite a lack of basis for concern about allergic reactions due to human antibody responses to these foreign proteins, essays were developed to determine HAGE (human anti-globulin antibody) levels that developed in patient sera following treatment with MAbs. Strategies were also devised to humanize MAbs and to temporarily block patient immune function with drugs in order to decrease the seroconversion rates, with considerable success. On the other hand, a survival advantage has been observed in some patients who developed a HAGA following treatment. This correlates with development of an anti-idiotype antibody cascade directed toward the MAbs used to treat these patients. What follows is a selective review of HAGA and its effect on cancer treatment over the past 2 decades.

Lung function decline is a well-recognized complication following allogeneic SCT (allo-SCT). Reduced-intensity conditioning (RIC) and in vivo T-cell depletion by administration of antithymocyte globulin (ATG) may have a protective role in the occurrence of late pulmonary complications. This retrospective study reported the evolution of lung function parameters within the first 2 years after allo-SCT in a population receiving the same RIC regimen that included fludarabine and i.v. BU in combination with low-dose ATG. The median follow-up was 35.2 months. With a median age of 59 years at the time of transplant, at 2 years, the cumulative incidences of non-relapse mortality was as low as 9.7%. The cumulative incidence of relapse was 33%. At 2 years, the cumulative incidences of extensive chronic GVHD (cGVHD) and of pulmonary cGVHD were 23.1% and 1.9%, respectively. The cumulative incidences of airflow obstruction and restrictive pattern were 3.8% and 9.6%, respectively. Moreover, forced expiratory volume (FEV1), forced vital capacity (FVC) and FEV1/FVC ratio remained stable from baseline up to 2 years post transplantation (P=0.26, P=0.27 and P=0.07, respectively). These results correspond favorably with the results obtained with other RIC regimens not incorporating ATG, and suggest that ATG may have a protective pulmonary role after allo-SCT.

Full Text Available Protein profile of twelve healthy adult dogs averaging 14.2±5.4kg was evaluated after the inoculation of yellow scorpion venom (Tityus serrulatus. The animals were randomly divided in two experimental groups (G (n= 6: GI control, which received 0.5mL of phosphate buffered saline (PBS subcutaneously in the medial side of the left thigh (MSLT, and GII which received T. serrulatus venom (250μg/kg, diluted in 0.5mL of PBS subcutaneously in the MSLT. Blood samples were collected before the venom inoculation (time zero and after 2, 6, 12, 24, 48 and 72h to obtain serum for measurement of total proteins. The fractionated protein profile was done by electrophoresis on agarose films using Tris and Amido Black staining and quantification of albumin and globulin fractions by software. The results showed no changes in the levels of total proteins, albumin and α, β and γ globulin or reversal of the albumin:globulin ratio between the groups, concluding that the dose of 250μg/kg of Tityus serrulatus venom did not induce acute phase proteins in dogs.

Effects of ranavirus infection of red-eared sliders (Trachemys scripta elegans) on plasma proteins.

Ranavirus is an emerging disease that infects fish, amphibians, and reptiles. Ranavirus induces an inflammatory response leading to death in many susceptible species. Red-eared sliders (RES; Trachemys scripta elegans) are vulnerable to ranavirus infection and are economically significant chelonians kept in the pet trade and utilized in research. Early identification of RES with inflammatory diseases would allow for isolation of affected individuals and subsequent disease investigation, including molecular testing for ranavirus. Validation of an inexpensive, clinically relevant, and reproducible diagnostic test that detects inflammation in turtles is needed. Although commonly used, plasma protein electrophoresis to detect an inflammatory acute-phase protein response has not been evaluated in a controlled environment in turtles with experimentally induced inflammatory disease. The objective of this study was to measure plasma protein fractions by electrophoresis to determine if an acute-phase protein response occurs in RES during infection with a frog virus 3-like ranavirus (FV3-like virus) isolated from a chelonian. A Bradford assay and agarose gel electrophoresis (AGE) were performed using plasma collected during a study of the effect of temperature on the pathogenesis of ranavirus in RES. In RES at the time of viremia, total albumin (ALB(mg/ml)) and albumin to globulin ratio were significantly lower and beta-globulin percentage was significantly higher in RES exposed to ranavirus (n = 4) as compared to matched, uninfected RES (n = 8). In the last sample collected prior to death, total protein (TP(mg/ml)), ALB(mg/ml), alpha-globulin percentage, and total alpha-globulin (alpha(mg/ml)) were significantly lower in RES exposed to ranavirus (n = 4) than control individuals (n = 8). In summary, FV3-like virus induces a decrease in plasma albumin concentration at the onset ofviremia and decreases in TP(mg/ml, ALB(mg/ml), and alpha(mg/ml) concentrations prior to death in

Uric Acid or 1-Methyl Uric Acid in the Urinary Bladder Increases Serum Glucose, Insulin, True Triglyceride, and Total Cholesterol Levels in Wistar Rats

Directory of Open Access Journals (Sweden)

T. Balasubramanian

2003-01-01

Full Text Available In animals deprived of food for a long period, a drop in the fat mass below 5% of the total body mass results in an increase in blood glucocorticoids and uric acid levels, followed by foraging activity. Since the glucocorticoids increase the uric acid excretion, an increase in the level of uric acid in the bladder urine could be the signal for this feeding behaviour and subsequent fat storage. Accumulation of fat is associated with hyperglycaemia, hyperinsulinaemia, hyperlipidaemia, and hypercholesterolaemia as seen in the metabolic syndrome or hibernation. It is hypothesized that uric acid or its structurally related compound, 1-methyl uric acid (one of the metabolites of the methyl xanthines namely caffeine, theophylline, and theobromine present in coffee, tea, cocoa, and some drugs, can act on the urinary bladder mucosa and increases the blood glucose, insulin, triglyceride, and cholesterol levels. In rats, perfusion of the urinary bladder with saturated aqueous solution of uric acid or 1-methyl uric acid results in a significant increase in the serum levels of glucose, insulin, true triglyceride, and total cholesterol in comparison with perfusion of the bladder with distilled water at 20, 40, and 80 min. The uric acid or the 1-methyl uric acid acts on the urinary bladder mucosa and increases the serum glucose, insulin, true triglyceride, and total cholesterol levels.

This study examined conservation easements and their effectiveness at reducing phosphorus and solids transport to streams. The U.S. Geological Survey cooperated with the Minnesota Board of Water and Soil Resources and worked collaboratively with the Hawk Creek Watershed Project to examine the West Fork Beaver Creek Basin in Renville County, which has the largest number of Reinvest In Minnesota land retirement contracts in the State (as of 2013). Among all conservation easement programs, a total of 24,218 acres of agricultural land were retired throughout Renville County, and 2,718 acres were retired in the West Fork Beaver Creek Basin from 1987 through 2012. Total land retirement increased steadily from 1987 until 2000. In 2000, land retirement increased sharply because of the Minnesota River Conservation Reserve Enhancement Program, then leveled off when the program ended in 2002. Streamflow data were collected during 1999 through 2011, and total phosphorus and total suspended solids data were collected during 1999 through 2012. During this period, the highest peak streamflow of 1,320 cubic feet per second was in March 2010. Total phosphorus and total suspended solids are constituents that tend to increase with increases in streamflow. Annual flow-weighted mean total-phosphorus concentrations ranged from 0.140 to 0.759 milligrams per liter, and annual flow-weighted mean total suspended solids concentrations ranged from 21.3 to 217 milligrams per liter. Annual flow-weighted mean total phosphorus and total suspended solids concentrations decreased steadily during the first 4 years of water-quality sample collection. A downward trend in flow-weighted mean total-phosphorus concentrations was significant from 1999 through 2008; however, flow-weighted total-phosphorus concentrations increased substantially in 2009, and the total phosphorus trend was no longer significant. The high annual flow-weighted mean concentrations for total phosphorus and total suspended solids

In the present study, grape (Vitis vinifera L.) seed endosperm proteins were characterized after sequential fractionation, according to a modified Osborne procedure. The salt-soluble fraction (albumins and globulins) comprised the majority (58.4%) of the total extracted protein. The protein fractions analysed by SDS-PAGE showed similar bands, indicating different solubility of the same protein components. SDS-PAGE in non-reducing and reducing conditions revealed the polypeptide composition of the protein bands. The main polypeptides, which were similar in all the grape varieties analysed, were identified by LC-MS/MS as homologous to the 11S globulin-like seed storage proteins of other plant species, while a monomeric 43 kDa protein presented high homology with the 7S globulins of legume seeds. The results provide new insights about the identity, structure and polypeptide composition of the grape seed storage proteins. Copyright © 2014 Elsevier Ltd. All rights reserved.

Muscle mass plays an important role in determining cardiovascular and metabolic risks in polycystic ovary syndrome (PCOS). In addition, whether lean mass influences carotid intima-media thickness (IMT) in PCOS has not been assessed. Prospective investigation. Ninety-five women with PCOS were age- and weight-matched to 90 ovulatory controls. All women had dual X-ray absorptiometry for lean, fat and bone mass, and bone mass density (BMD). Serum testosterone, sex hormone-binding globulin, insulin, and glucose and carotid IMT were determined. Free androgen index (FAI) and insulin resistance (by QUICKI) were calculated. In PCOS, waist circumference and insulin were higher and QUICKI lower than in controls (Plean mass were higher in PCOS compared to controls (PPCOS (PPCOS patients had abnormal (> or = 0.9 mm) values. Lean mass correlated with fat parameters, insulin, QUICKI, and FAI, but not with total testosterone; and after adjustments for insulin and QUICKI, lean mass still correlated with fat mass (PLean mass correlated with IMT (Plean mass independently of insulin. Bone mass correlated with lean and fat mass, but not with insulin or androgen. PCOS patients with 'pathological' IMT values had higher % trunk fat, lean mass, and insulin, lower QUICKI, and higher testosterone and FAI compared with those with normal IMT. Lean mass is increased in PCOS, while bone mass is similar to that of matched controls. The major correlates of lean mass are fat mass and insulin but not androgen. Lean mass also correlated with IMT, and although influenced by insulin, small changes in IMT may partially reflect changes in muscle mass, while clearly abnormal values relate to more severe abnormalities of PCOS.

Full Text Available Severe aplastic anemia (SAA is probably an immune-mediated disorder, and immunosuppressive therapy is recommended for patients with no available donor for bone marrow transplant. Between October 1984 and November 1987, 25 consecutive children and adolescents with SAA with no HLA-compatible marrow donor received equine antithymocyte globulin (ATG (15 mg kg-1 day-1 for 10 days. The patients were evaluated 6 weeks, 6 months, and 12 months after starting ATG treatment. Thereafter, patients were evaluated yearly until July 1998. Median age was 10 years (range, 1.5-20 years, granulocyte counts on referral ranged from 0.032 to 1.4 x 10(9/l (median 0.256 x 10(9/l, and 12 patients had granulocyte counts <0.2 x 10(9/l. At a median follow-up of 9.6 years (range, 8.6-11.8 years, 10 patients (40% remained alive with good marrow function. No morphologic evidence of hematological clonal disorders has been observed, although two patients probably have acquired clonal chromosomal abnormalities (trisomy 8 and del(6q21, respectively. Responses to ATG were observed between 6 weeks and 6 months from the start of treatment in 60% of evaluable patients. The response rate was not different in patients whose granulocyte count at diagnosis was <0.2 x 10(9/l, or in those who were <10 years of age. This study supports the view that, when compared with supportive measures, ATG is an effective treatment for children or adolescents with SAA. Although these results are inferior to those reported for marrow transplantation or more intensive immunosuppressive regimens, these patients who responded to ATG are long-term survivors with stable peripheral blood counts and a low rate of relapse.

Total body irradiation: current indications; L`irradiation corporelle totale: les indications actuelles

The choice of dose and fractionation for total body irradiation is made difficult by the large number of considerations to be taken into account. The outcome of bone marrow transplantation after total body irradiation can be understood in terms of tumor cell killing, engraftment, and normal tissue damage, each of these endpoints being influenced by irradiation-, disease-, transplant-, and patient- related factors. Interpretation of clinical data is further hampered by the overwhelming influence of logistic constraints, the small numbers of randomized studies, and the concomitant variations in total dose and fraction size or dose rate. So far, three cautious conclusions can be drawn in order to tentatively adapt the total body irradiation schedule to clinically-relevant situations. Firstly, the organs at risk for normal tissue damage (lung, liver, lens, kidney) are protected by delivering small doses per fraction at low dose rate. This suggests that, when toxicity is at stake (e.g. in children), fractionated irradiation should be preferred, provided that inter-fraction intervals are long enough. Secondly, fractionated irradiation should be avoided in case of T-cell depleted transplant, given the high risk of graft rejection in this setting. An alternative would be to increase total (or fractional) dose of fractionated total body irradiation, but this approach is likely to induce more normal tissue toxicity. Thirdly, clinical data have shown higher relapse rates in chronic myeloid leukemia after fractionated or low dose rate total body irradiation, suggesting that fractionated irradiation should not be recommended, unless total (or fractional) dose is increased. Total body irradiation-containing regimens, primarily cyclophosphamide / total body irradiation, are either equivalent to or better than the chemotherapy-only regimens, primarily busulfan / cyclophosphamide. Busulfan / cyclophosphamide certainly represents a reasonable alternative, especially in patients who

Proteolytic cleavage or partial degradation of proteins is one of the important post-translational modifications for various biological processes, but it is difficult to analyze. Previously, we demonstrated that some subunits of the major rice (Oryza sativa L.) seed storage protein glutelin are partially degraded to produce newly identified polypeptides X1-X5 in mutants in which another major seed storage protein globulin is absent. In this study, the new polypeptides X3 and X4/X5 were immunologically confirmed to be derived from GluA3 and GluA1/GluA2 subunits, respectively. Additionally, the new polypeptides X1 and X2 were at least in part the α polypeptides of the GluB4 subunit partially degraded at the C-terminus. Simulated 2D-PAGE migration patterns of intact and partially degraded α polypeptides based on the calculation of their MWs and pIs enabled us to narrow or predict the possible locations of cleavage sites. The predicted cleavage sites were also verified by the comparison of 2D-PAGE patterns between seed-extracted and E. coli-expressed proteins of the intact and truncated α polypeptides. The results and methodologies demonstrated here would be useful for analyses of partial degradation of proteins and the structure-function relationships of rice seed protein bodies. © 2017 WILEY-VCH Verlag GmbH & Co.

2009-01-01

The relationship between the epicardial fat volume measured by 64-slice multidetector computed tomography (MDCT) and the extension and severity of coronary atherosclerosis was investigated. Both MDCT and conventional coronary angiography (CAG) were performed in 71 consecutive patients who presented with effort angina. The volume of epicardial adipose tissue (EAT) was measured by MDCT. The severity of coronary atherosclerosis was assessed by evaluating the extension of coronary plaques in 790 segments using MDCT data, and the percentage diameter stenosis in 995 segments using CAG data. The estimated volume of EAT indexed by body surface area was defined as VEAT. Increased VEAT was associated with advanced age, male sex, degree of metabolic alterations, a history of acute coronary syndrome (ACS) and the presence of total occlusions, and showed positive correlation with the stenosis score r=0.28, P=0.02) and the atheromatosis score (r=0.67, P 3 /m 2 ) to be the strongest independent determinant of the presence of total occlusions odds ratio 4.64. P=0.02). VEAT correlates with the degree of metabolic alterations and coronary atheromatosis. Excessive accumulation of EAT might contribute to the development of ACS and coronary total occlusions.

A simple and rapid Hepatitis A Virus (HAV titration assay based on antibiotic resistance of infected cells: evaluation of the HAV neutralization potency of human immune globulin preparations

Directory of Open Access Journals (Sweden)

Kaplan Gerardo G

2008-12-01

Full Text Available Abstract Background Hepatitis A virus (HAV, the causative agent of acute hepatitis in humans, is an atypical Picornaviridae that grows poorly in cell culture. HAV titrations are laborious and time-consuming because the virus in general does not cause cytopathic effect and is detected by immunochemical or molecular probes. Simple HAV titration assays could be developed using currently available viral construct containing selectable markers. Results We developed an antibiotic resistance titration assay (ARTA based on the infection of human hepatoma cells with a wild type HAV construct containing a blasticidin (Bsd resistance gene. Human hepatoma cells infected with the HAV-Bsd construct survived selection with 2 μg/ml of blasticidin whereas uninfected cells died within a few days. At 8 days postinfection, the color of the pH indicator phenol red in cell culture media correlated with the presence of HAV-Bsd-infected blasticidin-resistant cells: an orange-to-yellow color indicated the presence of growing cells whereas a pink-to-purple color indicated that the cells were dead. HAV-Bsd titers were determined by an endpoint dilution assay based on the color of the cell culture medium scoring orange-to-yellow wells as positive and pink-to-purple wells as negative for HAV. As a proof-of-concept, we used the ARTA to evaluate the HAV neutralization potency of two commercially available human immune globulin (IG preparations and a WHO International Standard for anti-HAV. The three IG preparations contained comparable levels of anti-HAV antibodies that neutralized approximately 1.5 log of HAV-Bsd. Similar neutralization results were obtained in the absence of blasticidin by an endpoint dilution ELISA at 2 weeks postinfection. Conclusion The ARTA is a simple and rapid method to determine HAV titers without using HAV-specific probes. We determined the HAV neutralization potency of human IG preparations in 8 days by ARTA compared to the 14 days required by the

Full Text Available Abstract Background High prevalence of obesity and cardiovascular disease is attributable to sedentary lifestyle and eating diets high in fat and refined carbohydrate while eating diets low in fruit and vegetables. Epidemiological studies have confirmed a strong association between eating diets rich in fruits and vegetables and cardiovascular health. The aim of this pilot study was to determine whether drinking fresh carrot juice influences antioxidant status and cardiovascular risk markers in subjects not modifying their eating habits. Methods An experiment was conducted to evaluate the effects of consuming 16 fl oz of daily freshly squeezed carrot juice for three months on cardiovascular risk markers, C-reactive protein, insulin, leptin, interleukin-1α, body fat percentage, body mass index (BMI, blood pressure, antioxidant status, and malondialdehyde production. Fasting blood samples were collected pre-test and 90 days afterward to conclude the study. Results Drinking carrot juice did not affect (P > 0.1 the plasma cholesterol, triglycerides, Apo A, Apo B, LDL, HDL, body fat percentage, insulin, leptin, interleukin-1α, or C-reactive protein. Drinking carrot juice decreased (P = 0.06 systolic pressure, but did not influence diastolic pressure. Drinking carrot juice significantly (P Conclusion Drinking carrot juice may protect the cardiovascular system by increasing total antioxidant status and by decreasing lipid peroxidation independent of any of the cardiovascular risk markers measured in the study.

The aim of this study is to determine the changes in serum protein and its fractions by using electrophoresis in Holstein cows during different months of pregnancy in comparison with non-pregnant cows and to determine hormonal levels including T4, T3 and progesterone hormones. The samples were taken from 40 pregnant cows during deferent months and 10 non-pregnant cows. Significant decrease in the levels of total protein, albumin and globulin were observed in the third and late month of pregnancy than in mid pregnancy where the values were 6.5, 3.1 and 3.4 g/dl for early months and 6.5, 3.2 and 3.3 g/dl for late month as compared to the non-pregnant cows. Significant increase in α-1globulin was observed during months of pregnancy by about 33.3%. The decrease in the levels of α-2, β and γ-globulins were recorded by about 10%, 45.3% and 21.6%, respectively. A marked decrease in T4 hormone (5.0 μg/dl) was observed in pregnant cows than in non-pregnant ones (7.1 μg/dl). Also, a decreasing T3 level (169 ng/dl) was recorded as compared to non-pregnant cows (221 ng/dl). High significant increase in progesterone level was recorded in the mid pregnancy until reached the maximum value (49.94 ng/ml) at the 7 th month of pregnancy then declined (2.42 ng/ml) at the late month of pregnancy. In conclusion, during pregnancy of Holstein dairy cows, a decline in protein fractions and thyroid hormonal levels were recorded during different months as compared to non- pregnant cows. The opposite trend was observed in progesterone levels. The increasing progesterone level at the mid pregnancy indicated its importance in the continuation of pregnancy and maintenance of fetus against maternal rejection.

Full Text Available We investigated 252 non-obese female subjects aged 13-39 years to evaluate if an exaggerated descent of sex hormone binding globulin (SHBG levels during adolescence can play a role in the development of hirsutism. Body hair was assessed according to Ferriman and Gallwey (FG, with a stringent criterion of normality of 4 and controls (FG Se investigaron 252 mujeres con peso normal, de 13 a 39 años de edad, para evaluar si un descenso exagerado en los niveles de la globulina transportadora de hormonas sexuales ("sex hormone binding globulin"; SHBG puede tener un rol en el desarrollo de hirsutismo. Este signo fue evaluado con la escala de Ferriman y Gallwey (FG, empleando un criterio riguroso de normalidad 4 y controles (FG < 4, ciclos menstruales regulares, sin acné. En adolescentes de 15-18 años, los valores de SHBG fueron menores en las "hirsutas", los niveles de FT fueron similares en ambos grupos y el índice de FG correlacionó inversamente con SHBG. En las mujeres de 19-39 años, los niveles de FT fueron mayores en las "hirsutas", los valores de SHBG fueron similares en ambos grupos y FG correlacionó positivamente con FT. Los valores más bajos de SHBG se observaron entre 15 y 18 años, pero la pendiente de disminución a partir de los valores de 13-14 años fue mayor en el grupo de "hirsutas". Los valores de FT se incrementaron progresivamente con la edad, pero el aumento fue mayor en el grupo de "hirsutas". Estos resultados sugieren un rol importante del descenso de SHBG en la adolescencia vs. un incremento más acentuado de los niveles de testosterona en las adultas, como factores que condicionan el desarrollo del hirsutismo en esos dos diferentes periodos de la vida.

Bacterial meningitis is a disease of pronounced clinical significance, especially in the developing world. Immediate treatment with antibiotics is essential, and no single test can provide a conclusive diagnosis. It is well established that elevated total protein in cerebrospinal fluid (CSF) is associated with bacterial meningitis. Brillouin spectroscopy is a widely used optical technique for noninvasive determination of the elastic moduli of materials. We found that elevated protein levels in CSF alter the fluid elasticity sufficiently to be measurable by Brillouin spectroscopy, with model healthy and diseased fluids distinguishable to marked significance (P = 0.014), which increases with sample concentration by dialysis. Typical raw output of a 2-stage VIPA Brillouin spectrometer: inelastically scattered Brillouin peaks (arrows) and elastically scattered incident radiation (center cross). © 2014 WILEY-VCH Verlag GmbH & Co.

Full Text Available ABSTRACT The aim of this study was to determine the effects of the replacement of different levels of protein derived from soybean meal with that from peas in broiler diets on serum protein fractions. A corn-soybean meal basal diet was formulated as the control diet (Control=C (NRC, 1994, and then pea was added to the control diet to replace 20% (P20 or 40% (P40 of the crude protein of the control diet. The diets were randomly fed to 12 pens per treatment, each housing five birds, for 42 days. Blood samples were collected from 36 birds (3 birds x 4 pens x3 treatments and the serum protein fractions were separated. Gamma-globulin percentage was higher in group P20 compared with C and P40 groups. Total protein, beta-globulin, and gamma-globulin concentrations were significantly higher in group P20 compared with those of both control and P40 group (p<0.05.

Full Text Available Background: The purpose of this study was to investigate the influence of tranexamic acid (TXA on functional outcomes in the immediate postoperative period after total knee arthroplasty (TKA. We hypothesized that the known benefits of TXA would confer measurable clinical improvements in physical therapy (PT performance, decrease pain, and decrease hospital length of stay (LOS. Methods: We retrospectively analyzed 560 TKA patients, including 280 consecutive patients whose surgery was performed before the initiation of a standardized TXA protocol and the first 280 patients who received TXA after protocol initiation. Outcome measurements included postoperative changes in hemoglobin and hematocrit, LOS, pain scores, destination of discharge, and steps ambulated with PT over 5 sessions. Results: TXA administration resulted in less overall drops in hemoglobin (P < .001 and hematocrit levels (P < .001. Moreover, patients administered TXA ambulated more than their counterparts during every PT session, which was statistically significant during the second (P = .010, third (P = .011, and fourth (P = .024 sessions. On average, the TXA cohort ambulated 20% more per PT session than patients who did not receive TXA (P < .001. TXA administration did not influence pain levels during PT, hospital LOS, or discharge destination in this investigation. Conclusions: It is well known that TXA reduces postoperative anemia, but this study also demonstrates that it confers early perioperative functional benefits for TKA patients. Potential mechanisms for this benefit include reduced rates of postoperative anemia and reduced rates of hemarthroses.

2000-01-01

In nutritional protein deficiency, numerous studies verified utilization of amino acids generated from tissue degradation in intensive protein synthesis. Unlike liver, muscle protein synthesis is extremely dependent on external supplies of essential amino acids. Prolonged nutritional protein deficiency results in decrease of body weight as well as total protein concentration, in particular in early days of starvation. In prolonged starvation during the war, significant decrease of body weight was registered in 70 subjects while their total protein concentration remained within the expected range and did not significantly differ the values recorded in the control group. Concentration of serum albumines in the control group was lower than the concentration recorded in the tested group, while the serum globulins concentration was higher in the control group. Although the difference in body weight between the tested and the control group was statistically significant, no significant difference in the concentration of total proteins, albumines and globulines was recorded.

Birth of new neurons in the hippocampus persists in the brain of adult mammals and critically underpins optimal learning and memory. The process of adult neurogenesis is significantly reduced following brain irradiation and this correlates with impaired cognitive function. In this study, we aimed to compare the long-term effects of two environmental paradigms (i.e. enriched environment and exercise) on adult neurogenesis following high-dose (10Gy) total body irradiation. When housed in standard (sedentary) conditions, irradiated mice revealed a long-lasting (up to 4 months) deficit in neurogenesis in the granule cell layer of the dentate gyrus, the region that harbors the neurogenic niche. This depressive effect of total body irradiation on adult neurogenesis was partially alleviated by exposure to enriched environment but not voluntary exercise, where mice were single-housed with unlimited access to a running wheel. Exposure to voluntary exercise, but not enriched environment, did lead to significant increases in microglia density in the granule cell layer of the hippocampus; our study shows that these changes result from local microglia proliferation rather than recruitment and infiltration of circulating Cx 3 cr1 +/gfp blood monocytes that subsequently differentiate into microglia-like cells. In summary, latent neural precursor cells remain present in the neurogenic niche of the adult hippocampus up to 8 weeks following high-dose total body irradiation. Environmental enrichment can partially restore the adult neurogenic process in this part of the brain following high-dose irradiation, and this was found to be independent of blood monocyte-derived microglia presence.

Do Work-Life Balance Policies Increase a Firm's Total Factor Productivity?: Evidence from panel data of Japanese firms (Japanese)

OpenAIRE

YAMAMOTO Isamu; MATSUURA Toshiyuki

2011-01-01

This paper examines how firms' policies for workers' work-life balance (WLB) affect total factor productivity (TFP) in the long run, by using panel data of Japanese firms from the 1990s. Although we observed a positive correlation between firms' WLB policies and their TFP, once controlling for unobserved firm heterogeneity, we found no causal relationship where WLB policies increase a firm's TFP in the long run. Under the following conditions, however, WLB policies would likely improve a firm...

Recent Advances in the Management of Foreign Body Syndrome in Cattle and Buffaloes: A Review

Directory of Open Access Journals (Sweden)

Ashraf M. Abu-Seida and Oday S. Al-Abbadi

2016-11-01

Full Text Available Foreign body syndrome (FBS is a fairly common disease of cattle and buffaloes, especially in the developing countries. This disease is caused by ingestion of indigestible metallic and non-metallic blunt or sharp foreign objects. It is associated with high economic losses and therefore an urgent science-based policy is required to control and manage this syndrome. Indiscriminate feeding habits, feed scarcity, industrialization and mechanization of agriculture are predisposing factors for FBS in bovine and bubaline. The condition is difficult to diagnose solely on the basis of clinical signs and physical examination. However, laboratory diagnosis and imaging techniques like radiography and ultrasonography can be of high diagnostic value in detecting the condition. Anemia, increased packed cell volume, neutrophilia with a left shift, increased total protein, globulin, total bilirubin, Alanine Aminotransferase, Alkaline Phosphatase, Phosphorus and decreased albumin/globulin ratio and Calcium are the common abnormal laboratory findings. Recently, ultrasonography has replaced radiography for diagnosis of FBS in bovine and bubaline due to its availability and accuracy in evaluation of features of the reticulum, detection of penetrating metallic objects, diagnosis and assessment of various sequelae of FBS including; local and diffuse traumatic reticuloperitonitis, reticular, splenic, hepatic, abdominal and thoracic abscesses, diaphragmatic hernia, traumatic pericarditis and pleuropneumonia. Although, FBS is ideally treated with rumenotomy, it can be prevented to a large extent by proper management practices, increasing the awareness among the livestock keepers, oral administration of rumen magnets at the age of one year and reapplication of a new magnet every 4 years in animals at high risk.

Full Text Available The objective of this paper was to determine the effect of levamisole (LEV on immunoglobulin concentration in the serum of boars exposed to 3-day stress induced by exogenous ACTH. Boars were assigned to 4 groups (n=7. The first group received LEV for 3 days (2.5 mg/kg BW, the second group received ACTH (10 μg/kg BW for 3 days and the third group received LEV for 3 consecutive days and ACTH for the following 3 days (2.5 mg/kg BW; ACTH 10 μg/kg BW. The control group received saline solution during the 6 days. Concentrations of cortisol, total protein, globulin, albumin and immunoglobulin (IgG, IgA and IgM were determined during treatments and on the 16th day post-administration. Cortisol concentration was increased in both ACTH treated groups during all three days of administration and the day after the last ACTH treatment (p<0.05. ACTH increased total protein levels during the stress period and over the next 16 days (p<0.05. However, in the LEV+ACTH group total protein levels were elevated only on day 1 and 2 of ACTH injection (p<0.05 and after the end of treatment on day 11 and 22 (p<0.05. LEV stimulated the increase of protein concentrations compared to control values after LEV treatment, on days 5, 14, 18 and 22 (p<0.05. Serum albumins were not affected by LEV or ACTH treatment. Globulin concentrations were increased throughout and on the 16th day after administration of ACTH in the ACTH and LEV+ACTH groups (p<0.05. Globulin concentrations did not differ between LEV and control groups of boars. ACTH treatment elevated serum IgG concentration during the stress period (p<0.05 and over the next 16 days (p<0.05. However, in the LEV+ACTH group of boars, IgG levels were elevated on days 1 and 3 after ACTH injection (p<0.05 and days 1 and 5 in the post-treatment period (p<0.05. LEV had no impact on IgG levels compared to the control boars. However, increased IgA concentrations in boars treated with LEV were determined on day 2 (p<0.05 and day 11 (p

Induced groundwater flux by increases in the aquifer's total stress.

Science.gov (United States)

Chang, Ching-Min; Yeh, Hund-Der

2015-01-01

Fluid-filled granular soils experience changes in total stress because of earth and oceanic tides, earthquakes, erosion, sedimentation, and changes in atmospheric pressure. The pore volume may deform in response to the changes in stress and this may lead to changes in pore fluid pressure. The transient fluid flow can therefore be induced by the gradient in excess pressure in a fluid-saturated porous medium. This work demonstrates the use of stochastic methodology in prediction of induced one-dimensional field-scale groundwater flow through a heterogeneous aquifer. A closed-form of mean groundwater flux is developed to quantify the induced field-scale mean behavior of groundwater flow and analyze the impacts of the spatial correlation length scale of log hydraulic conductivity and the pore compressibility. The findings provided here could be useful for the rational planning and management of groundwater resources in aquifers that contain lenses with large vertical aquifer matrix compressibility values. © 2014, National Ground Water Association.

Full Text Available The effect of 4 different diets, in terms of protein quantity and quality, on total serum protein (TSP, albumin and globulin was investigated. Non-pregnant mares that were not lactating (n = 36, pregnant mares that had foaled (n = 24 and their foals (n = 24 were used in this study. Daily total protein intake had no effect on blood protein concentrations in the mares. Total protein intake and quality (available essential amino-acids did affect the body mass of mares during lactation. When mares were fed the minimum recommended (National Research Council 1989 total daily protein, foal mass decreased by approximately 25 % at weaning compared to the foals whose dams were on a higher level of protein intake. The TSP concentrations of foals at birth were on average 10 g/ℓ lower than those of the mares. Albumin concentrations of foals during the first 60 days of life were on average 2-3 g/ℓ lower than those of the mares. Globulin concentrations of foals were approximately 5 g/ℓ lower than those of mares at weaning.

To compare the safety and efficacy of rabbit antithymocyte globulin (r-ATG) with basiliximab in renal transplant recipients for whom an early steroid withdrawal (ESW) regimen was planned. Single-center, retrospective, cohort study. Tertiary care medical center, including inpatient hospital stays and outpatient nephrology clinics. Ninety-nine consecutive adult recipients of living- or deceased-donor renal transplants between January 1, 2004, and December 31, 2007, in whom ESW was planned and who received either r-ATG or basiliximab; patients receiving an extended-criteria kidney donation or a donation after cardiac death were excluded. All patients received mycophenolate mofetil and tacrolimus as maintenance therapy with planned ESW. Induction therapy was either r-ATG 1.5 mg/kg/day for 4 days (68 patients) or basiliximab 20 mg on postoperative days 0 and 4 (31 patients). The primary composite end point of biopsy-proven acute rejection (BPAR), graft loss, and death occurred in 6 patients (9%) and 9 patients (29%) in the r-ATG and basiliximab groups at 1 year after transplantation, respectively (p=0.01), with rates of 7% (5/68 patients) and 26% (8/31 patients) for BPAR (p=0.02), 0% and 3% (1/31 patients) for graft loss (p=0.31), and 2% (1/68 patients) and 0% for patient death (p>0.99). Average time to first BPAR was significantly longer in the r-ATG group (mean ± SD 151.4 ± 82.9 vs 53.6 ± 68.4 days, p<0.01). Kidney function at 12 months was similar between the two groups. Rabbit-ATG was associated with a lower frequency and delayed onset of BPAR compared with basiliximab in renal transplant recipients who received an ESW regimen.

This paper presents an investigation of total ionizing dose (TID) induced image lag sources in pinned photodiodes (PPD) CMOS image sensors based on radiation experiments and TCAD simulation. The radiation experiments have been carried out at the Cobalt −60 gamma-ray source. The experimental results show the image lag degradation is more and more serious with increasing TID. Combining with the TCAD simulation results, we can confirm that the junction of PPD and transfer gate (TG) is an important region forming image lag during irradiation. These simulations demonstrate that TID can generate a potential pocket leading to incomplete transfer.

Clinical outcome of increased flexion gap after total knee arthroplasty. Can controlled gap imbalance improve knee flexion?

2017-06-01

Increased range of motion (ROM) while maintaining joint stability is the goal of modern total knee arthroplasty (TKA). A biomechanical study has shown that small increases in flexion gap result in decreased tibiofemoral force beyond 90° flexion. The purpose of this paper was to investigate clinical implications of controlled increased flexion gap. Four hundred and four TKAs were allocated into one of two groups and analysed retrospectively. In the first group (n = 352), flexion gap exceeded extension gap by 2.5 mm, while in the second group (n = 52) flexion gap was equal to the extension gap. The procedures were performed from 2008 to 2012. The patients were reviewed 12 months postoperatively. Objective clinical results were assessed for ROM, mediolateral and sagittal stability. Patient-reported outcome measures were the WOMAC score and the Forgotten Joint Score (FJS-12). After categorizing postoperative flexion into three groups (poor < 90°, satisfactory 91°-119°, good ≥ 120°) significantly more patients in group 1 achieved satisfactory or good ROM (p = 0.006). Group 1 also showed a significantly higher mean FJS-12 (group 1: 73, group 2: 61, p = 0.02). The mean WOMAC score was 11 in the first and 14 in the second group (n.s.). Increase in flexion gap did not influence knee stability. The clinical relevance of this study is that a controlled flexion gap increase of 2.5 mm may have a positive effect on postoperative flexion and patient satisfaction after TKA. Neither knee stability in the coronal and sagittal planes nor complications were influenced by a controlled increase in flexion gap. III.

Full Text Available Quinoa (Chenopodium quinoa Willd is an ancient Andean seed-producing crop well known for its exceptional nutritional properties and resistance to adverse environmental conditions, such as salinity and drought. Storage proteins, amino acid composition, and bioactive compounds play a crucial role in determining the nutritional value of quinoa seeds. Seeds harvested from three Chilean landraces of quinoa, one belonging to the salares ecotype (R49 and two to the coastal-lowlands ecotype, VI-1 and Villarrica (VR, exposed to two levels of salinity (100 and 300 mM NaCl were used to conduct a sequential extraction of storage proteins in order to obtain fractions enriched in albumins/globulins, 11S globulin and in prolamin-like proteins. The composition of the resulting protein fractions was analyzed by one- and two-dimensional polyacrylamide gel electrophoresis. Results confirmed a high polymorphism in seed storage proteins; the two most representative genotype-specific bands of the albumin/globulin fraction were the 30- and 32-kDa bands, while the 11S globulin showed genotype-specific polymorphism for the 40- and 42-kDa bands. Spot analysis by mass spectrometry followed by in silico analyses were conducted to identify the proteins whose expression changed most significantly in response to salinity in VR. Proteins belonging to several functional categories (i.e., stress protein, metabolism, and storage were affected by salinity. Other nutritional and functional properties, namely amino acid profiles, total polyphenol (TPC and flavonoid (TFC contents, and antioxidant activity (AA of protein extracts were also analyzed. With the exception of Ala and Met in R49, all amino acids derived from protein hydrolysis were diminished in seeds from salt-treated plants, especially in landrace VI-1. By contrast, several free amino acids were unchanged or increased by salinity in R49 as compared with VR and VI-1, suggesting a greater tolerance in the salares landrace

Spent coffee grounds are waste material generated during coffee beverage preparation. This by-product disposal causes a negative environmental impact, in addition to the loss of a rich source of nutrients and bioactive compounds. A rotating central composition design was used to determine the optimal conditions for the bioactivity of phenolic compounds obtained after the solid state fermentation of spent coffee grounds by Bacillus clausii . To achieve this, temperature and fermentation time were varied according to the experimental design and the total phenolic and flavonoid content, antioxidant activity and antimicrobial activity were determined. Surface response methodology showed that optimum bioprocessing conditions were a temperature of 37 °C and a fermentation time of 39 h. Under these conditions, total phenolic and flavonoid contents increased by 36 and 13%, respectively, in fermented extracts as compared to non-fermented. In addition, the antioxidant activity was increased by 15% and higher antimicrobial activity was observed against Gram positive and negative bacteria. These data demonstrated that bioprocessing optimization of spent coffee grounds using the surface response methodology was an important tool to improve phenolic extraction, which could be used as an antioxidant and antimicrobial agents incorporated into different types of food products.

This study was carried out to determine the level of certain biochemical variables reflecting the energy metabolic statuses during the first week of lactation in goats. A total of 120 Anglo-Nubian, Angora, Baladi, and Damascus does (30 does per breed) were used throughout 5 consecutive parities (30 does per parity) to investigate the effect of breed, parity, day of lactation, and their interaction on serum metabolites including total protein, albumin, globulin, glucose, total lipids, cholesterol, and transaminases. Blood samples were collected every other day during the first week of lactation. Baladi does had the greatest (P 0.05) after kidding. Baladi goats had the least (P 0.05) by breed whereas both rectal temperature and coefficient of heat tolerance were affected (P Baladi goats expressed an aspect of adaptability where their rectal temperature decreased and coefficient of heat tolerance increased with increasing parity number.

The aim of this study is to compare calculated free testosterone (cFT) and total testosterone (T) in predicting late-onset hypogonadism (LOH) in middle-aged and elderly males. We surveyed a random sample of 608 males between the ages of 45 and 87 years from Shanghai, China. The Aging Male Symptoms (AMS) questionnaire and the Androgen Deficiency in Aging Male (ADAM) questionnaire were completed by the subjects. Testosterone (T), sex hormone-binding globulin (SHBG), albumin, and other blood biochemical indexes were measured in 332 males. The corresponding cFT was obtained using the Vermeulen formula and the correlations between T and cFT were analyzed by SPSS statistical software. Among the 332 males who underwent biochemical evaluation, 289 males (87.0%) was positively screened by the ADAM questionnaire and 232 males (69.9%) by the AMS questionnaire. As suggested by linear regression, cFT exhibited a negative correlation with age in both ADAM+ and AMS+ group, whereas T did not appear to have significant correlation with age. Besides, there were statistically significant differences in cFT (Pmales. © 2016 Wiley Periodicals, Inc.

This experiment was conducted to study the importance of supplementing wheat germ to the diet of growing local goats in Egypt for improving their some blood biochemical components as well as growth performance. Forty goats with 4 months age and average initial body weight 5 ± 0.5 kg were used in the present study which lasted 5 months. The animals were divided randomly into two equal groups; the 1st group fed basic diet without supplement (control) and the 2nd group of animals fed on the same basic diet with supplemented wheat germ at the rate of 5 g/head/day. The body weight was recorded at the beginning and the end of the experiment to calculate the daily gain of body weight for each animal. Blood samples were withdrawn at the end of experiment to estimate some blood parameters concentrations including total protein, albumin, globulin, urea, creatinine, total cholesterol, Ca, P, Mg, Zn, immunoglobulin G (IgG), total antioxidants and triiodothyronine (T3). The results showed that the addition of wheat germ by the rate of 5 gm/ head/ day to the diet of growing goats significantly increased the concentrations of total proteins, globulin, phosphorus, magnesium and zinc and led to significant decrease in the levels of total cholesterol. Significant improvement in levels of IgG, total antioxidants and T3 hormone in the blood were also observed. In addition, there was significant improvement in the feed efficiency of growing goats although total and daily gains of treated animals were affected by the diet supplement. It could be concluded that addition of wheat germ (5 g/head/day) led to modification of all studied blood components and led to improved feed efficiency in growing local goats, therefore, it could be recommended to use the wheat germ in growth stages because the economic return to this addition is preferable.

The aim of the present study is to examine the physiological effect of supplemental palm oil fatty acids- Ca salt and buffer on some biochemical and hormonal levels, milk yield and composition for high yielding Holstein Friesian cows during transition period. Thirty six Holstein Friesian cows, aged 53±1.4 months and 739±19.86 kg body weight, were used. The cows were randomly divided into three groups; 12 cows each, control group, the second group received 4% calcium salt palm oil fatty acid (Ca-POFA) and the third group received Ca-POFA + buffer ( 0.5% sodium bicarbonate) for three weeks before and after parturition (transition period). Blood samples were collected at 21, 14, 7 and 2 days before and 2, 7, 14 and 21 days after parturition to assess total protein, albumin, globulin, glucose, cholesterol, creatinine, total lipids and total cholesterol in addition to cortisol and progesterone hormones. Milk yield were recorded for each animal and samples were taken after parturition at different intervals (7, 14 and 21 days) to assess milk composition. Significant decreases in total protein, globulin, total lipids, cortisol and progesterone levels in post-partum cows compared to pre-partum were improved after Ca-POFA + buffer supplementation. On the other hand, increased levels of serum albumin, cholesterol and creatinine were recorded in post-partum period which returned to the normal level as shown in albumin only after treatment with Ca-POFA + buffer. A continuous increase in cholesterol and creatinine levels was observed as a result of supplementation of Ca-POFA + buffer (0.5% sodium bicarbonate). Significant improvements in milk yield, 4% FCM and GE were determined after Ca-POFA + buffer supplementation whereas non-significant changes were recorded in total solids, fat, protein and ash content of milk. In the present study, supplementation of cows in transition period with Ca-POFA + buffer (0.5% sodium bicarbonate) can improve the levels of some blood components

To characterize metabolic features of women with polycystic ovary syndrome (PCOS) by exercise behavior and determine relative health benefits of different exercise intensities. Cross-sectional study. Tertiary academic institution. Three hundred and twenty-six women aged 14-52 years-old with PCOS by Rotterdam criteria examined between 2006 and 2013. International Physical Activity Questionnaire (IPAQ) administered to classify patients into three groups based on Department of Health and Human Services (DHHS) Guidelines of vigorous, moderate, and inactive, along with physical examination and serum testing. Blood pressure, body mass index (BMI), waist circumference, fasting lipids, fasting glucose and insulin, 2-hour 75-gram oral glucose tolerance, homeostatic model assessment of insulin resistance (HOMA-IR). The DHHS guidelines for adequate physical activity were met by 182 (56%) women. Compared with moderate exercisers and inactive women, the vigorous exercisers had lower BMI and lower HOMA-IR; higher levels of high-density lipoprotein cholesterol and sex hormone-binding globulin; and a reduced prevalence of the metabolic syndrome. In a multivariate logistic regression analysis controlling for age, BMI, and total energy expenditure, every hour of vigorous exercise reduced a patient's odds of metabolic syndrome by 22% (odds ratio 0.78; 95% confidence interval, 0.62, 0.99). Women with PCOS who met DHHS guidelines for exercise demonstrated superior metabolic health parameters. Vigorous but not moderate activity is associated with reduced odds of the metabolic syndrome, independent of age, BMI, and total energy expenditure. PCOS patients should be encouraged to meet activity guidelines via vigorous physical activity. Copyright © 2016 American Society for Reproductive Medicine. Published by Elsevier Inc.

Full Text Available The importance of biomarkers to predict recovery following total hip arthroplasty (THA is still unclear to clinicians. To assess the preoperative biomarkers of patients with pseudoarthrosis of the femoral neck and their dynamics in the early postoperative period after THA, 50 patients aged 33 to 82 years old, 18 males and 32 females diagnosed with pseudoarthrosis of the femoral neck after failed internal fixation and failed conservative management were studied. The control group consisted of 30 healthy people aged 27 to 50 years, 13 males, 17 females. Patients’ blood was examined for biochemical markers upon admission, and then on the 7th and 14th days after surgery. Their blood serum content of total protein, albumin, glycoproteins, sialic acids, chondroitin sulfates, haptoglobin, glucose, cholesterol, triglycerides, ALT, AST, alkaline phosphatase, GGT, acid phosphatase, thymol index; interleukins (IL-1, IL-4 and IL-6. and C-reactive protein was measured. The content of glycoproteins in the blood exceeded the norm by 2.3 times, chondroitin sulfate by 4.7 times, sialic acids by 1.5 times, haptoglobin by 55.8%, fibrinogen by 19.1%, globulin by 19,6%, alkaline phosphatase activity by 72.3%, IL-1 by 94.7 and IL-6 by 3 times, C-reactive protein by 2.6 times. After THA there was a gradual decrease in blood biochemical and immunological markers. The most informative laboratory markers were glycoproteins, chondroitin sulfates, sialic acids, haptoglobin, activity of alkaline phosphatase, IL-1, IL-6 and IL-4, and C-reactive protein. Subsequent research is required to validate these dynamics.

A transient increase in total head phosphotyrosine levels is observed upon the emergence of Aedes aegypti from the pupal stage

Full Text Available Phosphorylation and dephosphorylation of protein tyrosine residues constitutes a major biochemical regulatory mechanism for the cell. We report a transient increase in the total tyrosine phosphorylation of the Aedes aegypti head during the first days after emergence from the pupal stage. This correlates with an initial reduction in total head protein tyrosine phosphatase (PTP activity. Similarly, phosphotyrosine (pTyr-containing bands are seen in extracts prepared from both male and female heads and are spread among a variety of structures including the antennae, proboscis and the maxillary palps combined with the proboscis. Also, mosquitoes treated with sodium orthovanadate, a classical PTP inhibitor, show reduced blood-feeding activity and higher head tyrosine phosphorylation levels. These results suggest that pTyr-mediated signalling pathways may play a role in the initial days following the emergence of the adult mosquito from the pupal stage.

Obesity increases the risk of deep infection after total joint arthroplasty (TJA). Our objective was to determine whether there may be body mass index (BMI) and weight thresholds indicating a higher prosthetic joint infection rate. We included all 9,061 primary hip and knee arthroplasties (mean age 70 years, 61% women) performed between March 1996 and December 2013 where the patient had received intravenous cefuroxime (1.5 g) perioperatively. The main exposures of interest were BMI (5 categories: prosthetic joint infection. The mean follow-up time was 6.5 years (0.5-18 years). 111 prosthetic joint infections were observed: 68 postoperative, 16 hematogenous, and 27 of undetermined cause. Incidence rates were similar in the first 3 BMI categories (infection from the early postoperative period onward (adjusted HR = 2.1, 95% CI: 1.3-3.6). BMI ≥ 35 or weight ≥ 100 kg may serve as a cutoff for higher perioperative dosage of antibiotics.

Beginning in November 1981, eight patients with end stage diabetic nephropathy underwent renal cadaveric transplantation after TLI. Transplantation was done between 2 to 11 days after the end of a fractionated TLI to a total dose of 20 to 30 Gy. During the same observation period, 60 nondiabetic patients with end stage renal disease of different origin also received a cadaveric kidney graft, with a conventional regimen of immunosuppression that consists of anti-lymphocyte-globulin, tapering high doses of prednisone, and azathioprine. Phytohemagglutinin (PHA)-, concanavalin A (con A)-, and pokeweed mitogen (PWM)-induced blastogenesis, as well as the mixed lymphocyte reaction (MLR) and the cell-mediated lympholysis (CML) decreased progressively during the first months after conventional immunosuppression to 50% of the pretransplantation level, and remained there for the first year after transplantation. These tests were much more impaired after TLI and again no recovery occurred during the first year. In the clinic, the more profound immunosuppression in TLI patients was more frequently associated with viral infections (cytomegalovirus and herpes zoster). The incidence of rejections, however, was somewhat less frequent in the TLI-treated group and occurred significantly later. After TLI, the mean cumulative dose of steroids needed for kidney transplantation during the first year after transplantation could be substantially reduced

The percentage of obese postmenopausal women with metabolic syndrome is rising, and physical factors associated with the metabolic syndrome prevalence or incidence are also rising, including high body mass index (BMI), visceral fat area (VFA), low plasma sex hormone-binding globulin (SHBG) levels, and low cardiorespiratory fitness. Therefore, we investigated the influence of aerobic exercise on SHBG, body fat index (BFI), and metabolic syndrome factors in obese postmenopausal Korean women. Thirty healthy postmenopausal, women aged 53.46 ± 2.4 years and with over 32% body fat, were randomly assigned to an aerobic exercise group (EX; n=15) or to a "nonexercise" control (Con; n=15) group. The primary outcome measurements were serum SHBG, lipid profiles, insulin levels, and metabolic syndrome factors. Secondary outcome measurements were body composition, VFA, blood pressure (BP), and homeostasis model assessment of insulin resistance (HOMA-IR). Posttraining body weight and BFI (Pmetabolic syndrome factors (Pexercise group but not in the control group. SHBG levels also showed a significant positive correlation with high-density lipoprotein cholesterol (HDL-C) and significant negative correlations withglucose, diastolic blood pressure, fat mass, BMI, and percent body fat (Pexercise improves body composition, SHBG, insulin levels, and metabolic syndrome factors. These findings suggest that in obesepostmenopausal Korean women, 16 weeks of aerobic exercise is effective for preventing the metabolic syndrome caused by obesity.

A new available oxidizing agent, 1, 3, 4, 6-tetra chloro-3α, diphenyl glycoluril(iodogen) was compared with chloramine-T (Ch-T), Iodine-mono chloride (I Cl) and N-Bromo succinimide (NBS) in the radio-iodination of gamma-globulin (γ-G) with 'no-carrier-added' (nca) Na 131 I (T 1/2=8 d). In Phosphate and acetate buffer solution, the optimum reaction conditions with respect to PH, concentration of oxidizing agent, reaction time and concentration of γ-G were determined. The optimum conditions which were found require 100μ l of buffer (pH 7.4, 0.025 M), 500μg γ-G (0.003 μmol), (10-40) μg of oxidizing agent and the desired amount of carrier-free radioiodine. Highest radiochemical yield (>85-90%) were obtained at pH 7.4. Separation and identification of the labelled products were achieved by means of high performance liquid chromatography (HPLC) and thin layer chromatography (TLC). 8 figs., 1 tab

Dietary natural plant secondary metabolites (PSM) extracted from a pomegranate peel (PP) byproduct have the potential to improve milk yield and the milk fatty acid profile of dairy cows. This experiment was performed to assess the influence of different dietary levels of PP extract (PPE) on feedlot performance, ruminal status, nutrient utilization, and antioxidant status in fattening Moghani lambs. Thirty-two lambs (initial BW of 22 ± 1.2 kg) were used in a completely randomized design with a 72-d period and 4 treatments: PPE0 (no extract), PPE15 (15 mL PPE/kg of diet DM), PPE30 (30 mL PPE/kg of diet DM), and PPE45 (45 mL PPE/kg of diet DM). Feed intake, lamb growth, diet digestibility, microbial nitrogen (N) synthesis (MNS), N retention, rumen parameters, and blood metabolites were determined. The addition of PPE to the diet of lambs had no effect on DMI (linear [L], = 0.96; quadratic [Q], = 0.65). In vivo digestibility coefficients of DM, OM, CP, and Ash-free NDF were not affected (L, ≥ 0.28; Q, ≥ 0.26) by different levels of PPE, but it increased ADG (L, = 0.045; Q, = 0.19) and G:F (L, = 0.046; Q, = 0.20). Rumen pH, VFA concentrations, and acetate-to-propionate ratio were not affected (L, ≥ 0.14; Q, ≥ 0.23) by PPE supplementation. Dietary inclusion of PPE decreased the ruminal concentration of ammonia N (L, = 0.014; Q, = 0.67), total protozoa enumeration (L, concentrations of glucose, triglycerides, cholesterol, total protein, albumin, or albumin-to-globulin ratio. Blood urea N (L, = 0.021; Q, = 0.32) decreased with dietary addition of PPE, while total antioxidant capacity (TAC) in the rumen fluid (L, = 0.032; Q, = 0.64) and TAC in the blood (L, = 0.041; Q, = 0.51) increased. Overall, dietary inclusion of PPE, up to 45 mL/kg of diet DM, linearly improved animal growth, N retention, and antioxidant capacities of the blood and rumen fluid. The PPE is a safe natural additive for use in sheep diets that can help to reduce environmental pollution by reducing

Full Text Available Abstract Background Prenatal factors may contribute to the development of peanut allergy. We evaluated the risk of childhood peanut allergy in association with pregnancy exposure to Rh immune globulin, folic acid and ingestion of peanut-containing foods. Methods We conducted a web-based case-control survey using the Anaphylaxis Canada Registry, a pre-existing database of persons with a history of anaphylaxis. A total of 1300 case children with reported peanut allergy were compared to 113 control children with shellfish allergy. All were evaluated for maternal exposure in pregnancy to Rh immune globulin and folic acid tablet supplements, as well as maternal avoidance of dietary peanut intake in pregnancy. Results Receipt of Rh immune globulin in pregnancy was not associated with a higher risk of peanut allergy (odds ratio [OR] 0.86, 95% confidence interval [CI] 0.51 to 1.45, nor was initiation of folic acid tablet supplements before or after conception (OR 0.53, 95% CI 0.19 to 1.48. Complete avoidance of peanut-containing products in pregnancy was associated with a non-significantly lower risk of peanut allergy (OR 0.53, 95% CI 0.27 to 1.03. Conclusion The risk of childhood peanut allergy was not modified by the following common maternal exposures in pregnancy: Rh immune globulin, folic acid or peanut-containing foods. Clinical implications Rh immune globulin, folic acid supplement use and peanut avoidance in pregnancy have yet to be proven to modulate the risk of childhood anaphylaxis to peanuts. Capsule Summary Identification of prenatal factors that contribute to peanut allergy might allow for prevention of this life-threatening condition. This article explores the role of three such factors.

Pecans (cv. Desirable) contained approximately 10% protein on a dry weight basis. The minimum nitrogen solubility (5.9-7.5%) at 0.25-0.75 M trichloroacetic acid represented the nonprotein nitrogen. Among the solvents assessed for protein solubilization, 0.1 M NaOH was the most effective, while borate saline buffer (pH 8.45) was judged to be optimal for protein solubilization. The protein solubility was minimal in the pH range of 3-7 and significantly increased on either side of this pH range. Increasing the NaCl concentration from 0 to 4 M significantly improved ( approximately 8-fold increase) protein solubilization. Following Osborne protein fractionation, the alkali-soluble glutelin fraction (60.1%) accounted for a major portion of pecan proteins followed by globulin (31.5%), prolamin (3.4%), and albumin (1.5%), respectively. The majority of pecan polypeptides were in the molecular mass range of 12-66 kDa and in the pI range of 4.0-8.3. The pecan globulin fraction was characterized by the presence of several glycoprotein polypeptides. Lysine was the first limiting essential amino acid in the defatted flour, globulin, prolamin, and alkaline glutelin fractions. Leucine and tryptophan were the first limiting essential amino acids in albumin and acid glutelin fractions, respectively. Rabbit polyclonal antibodies detected a range of pecan polypeptides in the 12-60 kDa range, of which the globulin fraction contained the most reactive polypeptides.

Plasma glucocorticoids (GCs) are commonly used as measures of stress in wildlife. A great deal of evidence indicates that only free GC (GC not bound by the specific binding protein, corticosteroid-binding globulin, CBG) leaves the circulation and exerts biological effects on GC-sensitive tissues. Free hormone concentrations are difficult to measure directly, so researchers estimate free GC using two measures: the binding affinity and the binding capacity in plasma. We provide an inexpensive saturation binding method for calculating the binding affinity (equilibrium dissociation constant, K d) of CBG that can be run without specialized laboratory equipment. Given that other plasma proteins, such as albumin, also bind GCs, the method compensates for this non-specific binding. Separation of bound GC from free GC was achieved with dextran-coated charcoal. The method provides repeatable estimates (12% coefficient of variation in the red squirrel, Tamiasciurus hudsonicus), and there is little evidence of inter-individual variation in K d (range 2.0-7.3 nM for 16 Richardson's ground squirrels, Urocitellus richardsonii). The K d values of 28 mammalian species we assessed were mostly clustered around a median of 4 nM, but five species had values between 13 and 61 nM. This pattern may be distinct from birds, for which published values are more tightly distributed (1.5-5.1 nM). The charcoal separation method provides a reliable and robust method for measuring the K d in a wide range of species. It uses basic laboratory equipment to provide rapid results at very low cost. Given the importance of CBG in regulating the biological activity of GCs, this method is a useful tool for physiological ecologists.

Background Previous reports showed that outcome of rabbit antithymocyte globulin (rATG) was not satisfactory as the first-line therapy for severe aplastic anemia (SAA). We explored a modifying schedule of administration of rATG. Design and Methods Outcomes of a cohort of 175 SAA patients, including 51 patients administered with standard protocol (3.55 mg/kg/d for 5 days) and 124 cases with optimized protocol (1.97 mg/kg/d for 9 days) of rATG plus cyclosporine (CSA), were analyzed retrospectively. Results Of all 175 patients, response rates at 3 and 6 months were 36.6% and 56.0%, respectively. 51 cases received standard protocol had poor responses at 3 (25.5%) and 6 months (41.2%). However, 124 patients received optimized protocol had better responses at 3 (41.1%, P = 0.14) and 6 (62.1%, P = 0.01). Higher incidences of infection (57.1% versus 37.9%, P = 0.02) and early mortality (17.9% versus 0.8%, P<0.001) occurred in patients received standard protocol compared with optimized protocol. The 5-year overall survival in favor of the optimized over standard rATG protocol (76.0% versus. 50.3%, P<0.001) was observed. By multivariate analysis, optimized protocol (RR = 2.21, P = 0.04), response at 3 months (RR = 10.31, P = 0.03) and shorter interval (<23 days) between diagnosis and initial dose of rATG (RR = 5.35, P = 0.002) were independent favorable predictors of overall survival. Conclusions Optimized instead of standard rATG protocol in combination with CSA remained efficacious as a first-line immunosuppressive regimen for SAA. PMID:23554855

The efficacy and safety of daclizumab and anti-thymocyte globulin-Fresenius (ATG-F) as induction therapy in kidney transplantation (KT) were investigated in 45 KT performed in our center between March and May 2002. Group II (n=10) received daclizumab as induction therapy, and Group I (n=35) were induced with a single intraoperative bolus therapy of ATG-F. All patients were at low-risk, and the recipient and donor demographics, as well the immunosuppression regimen employed were comparable in both groups. Drug safety, assessed by the occurrence of side effects, was almost comparable in the two groups, except for more thrombocytopenia in Group II (P<0.0004). Acute rejection (AR) occurred in 10% in Group I and 11.4% in Group II (P=NS). There were more infections in Group II (42.8%) than in Group I (10%) (P<0.009). Bacterial and viral infections were more common in Group II (69 and 23%) than in Group I (10 and 0%) (P<0.05). The hospital stay was similar in both groups. Mean serum creatinine levels upon discharge, at 1, 3 and 6 months were: 1.23+/-0.11, 1.21+/-0.06, 1.25+/-0.11 and 1.35+/-0.08 in Group I and 2.18+/-0.43, 1.49+/-0.16, 1.49+/-0.16 and 1.35+/-0.08 in Group II, respectively. While better serum creatinine levels were observed in Group I upon discharge (P<0.048), this was due to the presence of more sensitized patients in Group II. The 6 months actuarial patient and graft survival were identical in both groups (100 and 100%, respectively). Although both daclizumab and ATG-F were effective and safe as induction therapy in KT, less bacterial and viral infections and lower early serum creatinine levels were noted in daclizumab-treated patients.

T-cell costimulation has been shown to provide positive signals for T-cell activation and generation of effector activity. In this study, we analyzed the presence of antibodies (Abs) against the T-lymphocyte costimulatory molecules CD28, CTLA-4, CD80, and CD86 in anti-T-lymphocyte (ATG) and antithymocyte (TMG) globulin preparations to address their mechanism of action. We focused our attention on the role of CTLA-4-specific Abs in the immunosuppressive effect of ATG/TMG, because anti-CTLA-4 agonistic Abs may suppress T-cell proliferation and nonagonistic Abs may lead to T-cell depletion through an Ab-dependent cell cytotoxicity mechanism. ATG/TMG and patients' sera were tested for binding to recombinant human costimulatory molecules by ELISA techniques. CTLA-4 specificity was also analyzed by cytoplasmic immunofluorescence staining of a CTLA-4 transfectant by competitive inhibition immunofluorescence and by cell proliferation assay in allogeneic mixed lymphocyte reaction (MLR). Either ATG or TMG predominantly contained anti-CTLA-4 Abs, with higher reactivity in ATG followed by anti-CD86 and -CD28 Abs, whereas anti-CD80 Abs were found only in ATG. Anti-CTLA-4 Abs present in ATG/TMG recognized the native form of CTLA-4 molecule, and their removal reduced the effect of ATG in an allogeneic MLR. Kinetic studies indicated that such Abs were present in the sera of 12 ATG-treated leukemic patients up to 21 days after ATG administration. These data suggest that the novel anti-CTLA-4 Abs found in ATG may greatly contribute to its immunosuppressive effect, thus accounting for the absence of rejection and exceptionally low incidence of graft-versus-host disease in the group of patients analyzed.

In assessing clinical and pathophysiological development of type 2 diabetes (T2D), the critical role of the sex steroids axis is underappreciated, particularly concerning the sex-specific relationships with many relevant cardiometabolic outcomes. In this issue of the Journal of Diabetes, we provide a comprehensive overview of these significant associations of germline variants in the genes governing the sex steroid pathways, plasma levels of steroid hormones, and sex hormone-binding globulin (SHBG) with T2D risk that have been observed in many clinical and high-quality large prospective cohorts of men and women across ethnic populations. Together, this body of evidence indicates that sex steroids and SHBG should be routinely incorporated into clinical characterization of T2D patients, particularly in screening prediabetic patients, such as those with metabolic syndrome, using plasma levels of SHBG. Given that several germline mutations in the SHBG gene have also been directly related to both plasma concentrations of SHBG and clinical manifestation of T2D, targeting signals in the sex steroid axis, particularly SHBG, may have significant utility in the prediction and treatment of T2D. Further, many of the environmental endocrine disrupting chemicals may exert their potential adverse effects on cardiometabolic outcomes via either estrogenic or androgenic signaling pathways, highlighting the importance of using the sex steroids and SHBG as important biochemical markers in both clinical and population studies in studying sex-specific mechanisms in the pathogenesis of T2D and its complications, as well as the need to equitably allocate resources in studying both men and women. © 2016 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

Purpose Several open-label randomized studies have suggested that in vivo T-cell depletion with anti-T-lymphocyte globulin (ATLG; formerly antithymocyte globulin-Fresenius) reduces chronic graft-versus-host disease (cGVHD) without compromising survival. We report a prospective, double-blind phase III trial to investigate the effect of ATLG (Neovii Biotech, Lexington, MA) on cGVHD-free survival. Patients and Methods Two hundred fifty-four patients 18 to 65 years of age with acute leukemia or myelodysplastic syndrome who underwent myeloablative HLA-matched unrelated hematopoietic cell transplantation (HCT) were randomly assigned one to one to placebo (n =128 placebo) or ATLG (n = 126) treatment at 27 sites. Patients received either ATLG or placebo 20 mg/kg per day on days -3, -2, -1 in addition to tacrolimus and methotrexate as GVHD prophylaxis. The primary study end point was moderate-severe cGVHD-free survival. Results Despite a reduction in grade 2 to 4 acute GVHD (23% v 40%; P = .004) and moderate-severe cGVHD (12% v 33%; P < .001) in ATLG recipients, no difference in moderate-severe cGVHD-free survival between ATLG and placebo was found (2-year estimate: 48% v 44%, respectively; P = .47). Both progression-free survival (PFS) and overall survival (OS) were lower with ATLG (2-year estimate: 47% v 65% [ P = .04] and 59% v 74% [ P = .034], respectively). Multivariable analysis confirmed that ATLG was associated with inferior PFS (hazard ratio, 1.55; 95% CI, 1.05 to 2.28; P = .026) and OS (hazard ratio, 1.74; 95% CI, 1.12 to 2.71; P = .01). Conclusion In this prospective, randomized, double-blind trial of ATLG in unrelated myeloablative HCT, the incorporation of ATLG did not improve moderate-severe cGVHD-free survival. Moderate-severe cGVHD was significantly lower with ATLG, but PFS and OS also were lower. Additional analyses are needed to understand the appropriate role for ATLG in HCT.

This study designed to evaluate the hazardous effects of gamma-radiation and to investigate the role of high protein diet, vitamin C and vitamin E as radioprotectors in rats followed exposure to a single dose of whole body gamma irradiation of 7 Gy. 120 male albino rats were divided into six equal groups of 20 rats each : control, irradiated , high protein (P), vitamin C, vitamin E and combination (C + E + P) supplemented groups. The variation in levels of total protein, albumin, globulin, A/G ratio, cholesterol, triglycerides, urea, creatinine, corticosterone, testosterone, apoptosis and the activities of ALT ,AST ,LDH ,CK and CKMB were estimated for all groups. Serum corticosterone and testosterone detection were carried out according to the radioimmunoassay (RIA) technique. Serum apoptosis detection was carried out using the Enzyme-linked immunosorbent assay (ELISA). Analyses were carried out at the end of one week pre gamma irradiation, one and two weeks post gamma irradiation . In the irradiated group, an increase in serum triglycerides, urea, creatinine and testosterone levels, apoptosis and ALT, AST, CK, LDH activities were observed compared to control. While there was a decrease in both globulin and cholesterol levels and no changes in albumin level and CKMB activity. In almost supplemented groups, the reverse was occurred except in triglycerides, cholesterol, globulin and CK . Based on these biochemical observations, it was concluded that vitamin C and vitamin E treatment exerts a protective effect against irradiation damage while high protein diet has protective or ameliorative effects to some extent

Prior studies have reported mixed results regarding relationships between vitamin D, androgens, and sex hormone-binding globulin in patients with polycystic ovary syndrome. However, less is known regarding these associations in eumenorrheic, premenopausal women. Our objective was to study the relationships between serum vitamin D and androgen biomarkers in eumenorrheic women with a history of pregnancy loss who were attempting pregnancy. This was an analysis of a cohort of 1191 participants from the Effects of Aspirin in Gestation and Reproduction trial (2006-2012). Participants were attempting to conceive, aged 18-40 years, with 1-2 documented prior pregnancy losses and no history of infertility, and recruited from 4 academic medical centers in the United States. Serum vitamin D (25-hydroxyvitamin D) and hormone concentrations were measured at baseline. Vitamin D concentration was negatively associated with free androgen index (percentage change [95% confidence interval, -5% (-8% to -2%)] per 10 ng/mL increase) and positively associated with sex hormone-binding globulin (95% confidence interval, 4% [2-7%]), although not with total testosterone, free testosterone, or dehydroepiandrosterone sulfate after adjusting for age, body mass index, smoking status, race, income, education, physical activity, and season of blood draw. Overall, vitamin D was associated with sex hormone-binding globulin and free androgen index in eumenorrheic women with prior pregnancy loss, suggesting that vitamin D may play a role in the bioavailability of androgens in eumenorrheic women. We are limited in making assessments regarding directionality, given the cross-sectional nature of our study. Copyright © 2018. Published by Elsevier Inc.

The effects of total fasting for 31 +/- 10 days followed by re-alimentation with an 800 calorie diet on thyroid function, i.e. T4,T3,rT3,RT3U (resin T3 uptake), and TSH, and on TBG levels in serum were studied sequentially in obese hospitalized patients (N=18). Additionally, cortisol, growth hormone, prolactin, parathyrin and free fatty acids were followed as hormonal and metabolic parameters, respectively. Further, CBG, transferrin, alpha 2-haptoglobin and complement C'3 were measured as representatives of other serum proteins. Results before fasting: T4, T3, TBG, cortisol, CBG, alpha 2-haptoglobin and complement C'3 of the obese patients were elevated when compared with healthy normal weight controls, whereas rT3, T4/TBG ratio, T3/TBG ratio, TSH, coritsol/cbg ratio, growth hormone, prolactin, parathyrin and transferrin of the obese group were normal. RT3U and fT4 index were decreased in the obese patients. Results during fasting: Significant decreases were observed during fasting for the following parameters -- T3, TBG, T3/TBG ratio, transferrin, alpha 2-haptoglobin complement C'3. rT3, T4/TBG ratio, RT3U, fT4 index and FFA increased. T4, tsh response to TRH stimulation, cortisol, CBG, cortisol/cbg ratio, parathyrin, growth hormone and prolactin did not change. Results during re-alimentation: T3, TBG, T3/TBG ratio, TSH response to TRH, transferrin, alpha 2-haptoglobin and complement C'3 increased. Conversely, fT3, RT3U, FFA, cortisol and cortisol/cbg ratio decreased whereas the other parameters did not change. 1) There is no evidence for primary hypothyroidism in obese patients during prolonged fasting and re-alimentation. 2) The rapid decrease of T3 and increase of RT3U after initiation of fasting are not fully explained by the observed slower decreases in TBG. 3) The alterations of T3, rT3 and RT3U resemble in their kinetics the changes in FFA levels. 4) Fasting reduced the levels of only certain serum proteins, interestingly TBG, transferrin, alpha 2

In the ill hospitalized patient with clinically relevant malnutrition, there is a measurable decrease in the ratio of the total body potassium to total body water (TBK/TBW) and a detectable increase in the ratio of total exchangeable sodium to total exchangeable potassium (Nae/Ke). To evaluate body composition analyses in anorexia nervosa patients with chronic uncomplicated semistarvation, TBK and TBW were measured by whole body K40 counting and deuterium oxide dilution in 10 females with stable anorexia nervosa and 10 age-matched female controls. The ratio of TBK/TBW was significantly (p less than 0.05) higher in anorexia nervosa patients than controls. The close inverse correlation found in published studies between TBK/TBW and Nae/Ke together with our results suggest that in anorexia nervosa, Nae/Ke may be low or normal. A decreased TBK/TBW is not a good indicator of malnutrition in the anorexia nervosa patient. The use of a decreased TBK/TBW ratio or an elevated Nae/Ke ratio as a definition of malnutrition may result in inappropriate nutritional management in the patient with severe nonstressed chronic semistarvation.

Full Text Available The current study was designed to probe pathological effects of colistin in growing broilers. One hundred twenty day-old broiler chicks were divided into six equal groups A-F. These birds were injected colistin sulphate, 0, 5, 10, 20, 40 and 80 mg/kg BW respectively through intramuscular route. The different serum-biochemical parameters including total protein, albumen, globulin, ALT, AST, LDH, GGT, creatinine and BUN were determined at day 21 and 42 of experiment. The hematological parameters including RBC, WBC, PCV and Hb were determined twice. The serum total protein values were significantly higher in group E as compared with control group. At day 42 groups, C-E had significantly lower albumen values as compared to group A. The similar pattern was observed in globulin values. The creatinine & urea was also found significantly higher in group D and E at day 21 of experiment, while at day 42 all the groups having significantly higher urea level in comparison with group A indicating nephrotoxic effect of colistin. The serum enzymes including ALT and AST were significantly higher in group D & E as compared with group A, which is an indication of liver damage. The LDH and GGT values showed significantly increasing trend in experimental groups compared with control. The erythrocytes and leucocytes count were significantly higher in control and low dose groups as compared with higher colistin dose groups. It is concluded that lavish parenteral administration of colistin resulted in increased levels of hepato-renal serum indicators and lower values of hematological parameters.

Protein electrophoresis of serum samples from endangered, wild whooping cranes ( Grus americana ) was performed to help assess the health of the only self-sustaining, migratory population in North America. Serum samples from wild adult cranes (n = 22) were taken at Aransas National Wildlife Refuge, Texas, USA during winter. Wild juvenile cranes (n = 26) were sampled at Wood Buffalo National Park, Northwest Territories, Canada, in midsummer. All captive crane samples were acquired from the International Crane Foundation, Baraboo, WI, USA. Captive adult cranes (n = 30) were sampled during annual examinations, and archived serum samples from captive juvenile cranes (n = 19) were selected to match the estimated age of wild juveniles. Wild juveniles had significantly lower concentrations of all protein fractions than wild adults, except for prealbumin and γ globulins. All protein fraction concentrations for wild juveniles were significantly lower compared with captive juveniles, except for prealbumin and γ globulins, which were higher. Wild adults had significantly greater γ globulin concentrations than captive adults. Captive juveniles had significantly lower prealbumin and albumin concentrations and albumin : globulin ratios than captive adults. The higher γ globulin concentrations in wild versus captive cranes are likely because of increased antigenic exposure and immune stimulation. Protein fraction concentrations vary significantly with age and natural history in this species. Reference intervals for serum protein electrophoresis results from captive adult whooping cranes are provided in this study.

Total knee replacements (TKRs) are being increasingly performed in patients aged age of the patient and prosthesis survival following primary TKR using nationwide data collected from the Finnish Arthroplasty Register. From Jan 1, 1997 through Dec 31, 2003, 32,019 TKRs for primary or secondary osteoarthritis were reported to the Finnish Arthroplasty Register. The TKRs were followed until the end of 2004. During the follow-up, 909 TKRs were revised, 205 (23%) due to infection and 704 for other reasons. Crude overall implant survival improved with increasing age between the ages of 40 and 80. The 5-year survival rates were 92% and 95% in patients aged 65 years of age (p age groups 65 years remained after adjustment for these factors (p age impairs the prognosis of TKR and is associated with increased revision rates for non-infectious reasons. Diagnosis, sex, type of TKR, use of patellar component, and fixation method partly explain the differences, but the effects of physical activity, patient demands, and obesity on implant survival in younger patients warrant further research.

Contemporarily, food production without food additives is very rare. Increasingly often, however, scientific works report on adverse effects of specified, single food additives on the body. Data is, in turn, lacking on the synergistic effect of a mixture of different food additives on body functions and its main metabolic pathways. The objective of this study, an animal model, was to evaluate if and in what way the compound of chosen and most frequently used and consumed food additives, along with the change of diet composition to processed, purified, influence the selected markers of protein metabolism. The animals were divided into four groups, which were fed with compound of feed pellets: group I and II with basic compound, group III and IV with modified compound in which part of the full grain was replaced by isocalorie wheat flour type 500 and saccharose. Animals from groups I and III received tap water, which was standing for some time, to drink. Animals from groups II and IV received solution of chosen additives to food and next they were given water to drink. The amount of given food additives was evaluated by taking into consideration their consumption by people recalculated to 1 kg of their body mass. The experiment spanned for 7 weeks. It was ascertained that the applied additives caused significant changes in total protein concentration and its fractions: albumin, alpha1-globulin, alpha2-globulin, beta-globulin and gamma-globulin in the blood serum of the animals under research, which can indicate and contribute to disclosure of creation of undesirable food reaction, especially when recommended levels of consumption of those additives are being exceeded. The organism response to the applied additives and accompanying it change of diet was essentially connected to sex of the animals. Undesirable character of changes taking place under the influence of applied additives, was observed both in animals fed with basic feed and modified feed with various

BACKGROUND: Butter is known to have a cholesterol-raising effect and, therefore, has often been included as a negative control in dietary studies, whereas the effect of moderate butter intake has not been elucidated to our knowledge. OBJECTIVE: We compared the effects of moderate butter intake...... their habitual diets. The study included 47 healthy men and women (mean ± SD total cholesterol: 5.22 ± 0.90 mmol/L) who substituted a part of their habitual diets with 4.5% of energy from butter or refined olive oil. RESULTS: Study subjects were 70% women with a mean age and body mass index (in kg/m(2)) of 40.......4 y and 23.5, respectively. Butter intake increased total cholesterol and LDL cholesterol more than did olive oil intake (P cholesterol compared with the run-in period (P

Few studies have analyzed the association between elevated BMI and complications after total shoulder arthroplasty (TSA). Previous studies have not consistently arrived at the same conclusion regarding whether obesity is associated with a greater number of postoperative complications. We used a national surgical database to compare the 30-day complication profile and hospitalization outcomes after primary TSA among patients in different BMI categories. We asked: (1) Is obesity associated with an increased risk of complications within 30 days of primary TSA? (2) Is obesity associated with increased operative time? The American College of Surgeons National Surgical Quality Improvement Program(®) database for 2006 to 2012 was queried to identify all patients who underwent a primary TSA for osteoarthritis of the shoulder. The ACS-NSQIP(®) database was selected for this study as it is a nationally representative database that provides prospectively collected perioperative data and a comprehensive patient medical profile. Exclusion criteria included revision TSA, infection, tumor, or fracture. We analyzed 4796 patients who underwent a primary TSA for osteoarthritis of the shoulder. Patients who underwent a TSA were divided in four BMI categories: normal (18.5-25 kg/m(2)), overweight (25-30 kg/m(2)), obesity Class 1 (30-35 kg/m(2)), and obesity Class 2 or greater (> 35 kg/m(2)). Perioperative hospitalization data and 30-day postoperative complications were compared among different BMI classes. Differences in patient demographics, preoperative laboratory values, and preexisting patient comorbidities also were analyzed among different BMI groups, and multivariate analysis was used to adjust for any potential confounding variables. There was no association between BMI and 30-day complications after surgery (normal as reference, overweight group relative risk: 0.57 [95% CI, 0.30-1.06], p = 0.076; obesity Class 1 relative risk: 0.52 [95% CI, 0.26-1.03], p = 0.061; obesity

To retrospectively evaluate the outcome and toxicity of total lymphoid irradiation (TLI) based conditioning regimen for allogeneic hematopoietic stem cell transplantation (HSCT) in severe aplastic anemia (SAA) patients who experienced an engraftment failure from prior HSCT or were heavily transfused. Between 1995 and 2006, 20 SAA patients received TLI for conditioning of HSCT. All patients were multi-transfused or had long duration of disease. Fifteen (75%) patients had graft failure from prior HSCT. In 18 (90%) patients, the donors were human leukocyte antigen identical siblings. The stem cell source was the peripheral blood stem cell in 15 (75%) patients. The conditioning regimen was composed of antithymocyte globulin plus TLI with a median dose of 750 cGy in 1 fraction. The graft-versus-host disease (GVHD) prophylaxis used cyclosporine with methotrexate. With a median follow-up of 10.8 years, graft failures developed in 6 patients. Among them, 3 patients received their third HSCT to be engrafted finally. The Kaplan-Meier overall survival rate was 85.0% and 83.1% at 5 and 10 years, respectively. The incidence of acute and chronic GVHD was 20% and 20%, respectively. None of the patients have developed a malignancy after HSCT. In our study, TLI based conditioning in allogeneic HSCT was feasible with acceptable rates of GVHD in SAA patients who experienced graft failure from prior HSCT or was at a high risk of graft rejection. We achieved relatively better results of engraftment and survival with a long term follow-up.

To retrospectively evaluate the outcome and toxicity of total lymphoid irradiation (TLI) based conditioning regimen for allogeneic hematopoietic stem cell transplantation (HSCT) in severe aplastic anemia (SAA) patients who experienced an engraftment failure from prior HSCT or were heavily transfused. Between 1995 and 2006, 20 SAA patients received TLI for conditioning of HSCT. All patients were multi-transfused or had long duration of disease. Fifteen (75%) patients had graft failure from prior HSCT. In 18 (90%) patients, the donors were human leukocyte antigen identical siblings. The stem cell source was the peripheral blood stem cell in 15 (75%) patients. The conditioning regimen was composed of antithymocyte globulin plus TLI with a median dose of 750 cGy in 1 fraction. The graft-versus-host disease (GVHD) prophylaxis used cyclosporine with methotrexate. With a median follow-up of 10.8 years, graft failures developed in 6 patients. Among them, 3 patients received their third HSCT to be engrafted finally. The Kaplan-Meier overall survival rate was 85.0% and 83.1% at 5 and 10 years, respectively. The incidence of acute and chronic GVHD was 20% and 20%, respectively. None of the patients have developed a malignancy after HSCT. In our study, TLI based conditioning in allogeneic HSCT was feasible with acceptable rates of GVHD in SAA patients who experienced graft failure from prior HSCT or was at a high risk of graft rejection. We achieved relatively better results of engraftment and survival with a long term follow-up.

SHABON, M.H.

2009-01-01

Curcuma longa is the scientific name of Turmeric, which can be found on spice racks worldwide. This herb is responsible for the yellow coloring of many Currie dishes. Female albino rats were treated with oral administration of curcumin for 14 days before γ-irradiation. γ Radiation was applied in 0.1, 0.75 and 2 Gy, 1 hour after the last dose of curcuma administration. Animals were divided into control and 6 treated groups, all were irradiated with γ-rays, only three were injected with curcumin. Blood collected 1 and 48 hours after irradiation. Serum total protein, albumin, globulins, cholesterol, triglycerides, SGOT and SGPT were determined.Curcuma was found to elevate the protein profile (total protein, albumin and globulin) and ameliorates the hyperlipidaemic effects of γ- radiation. Curcuma also improved the liver functions affected by γ- irradiation.The experiment concluded that curcuma can be used as a radioprotector for occupationally exposed individuals to low doses and low dose rates.

Full Text Available FIABA ONLUS (Italian Fund for Elimination of Architectural Barriers was founded in 2000 with the aim of promoting a culture of equal opportunities and, above all, it has as its main goal to involve public and private institutions to create a really accessible and usable environment for everyone. Total accessibility, Total usability and Total mobility are key indicators to define quality of life within cities. A supportive environment that is free of architectural, cultural and psychological barriers allows everyone to live with ease and universality. In fact, people who access to goods and services in the urban context can use to their advantage time and space, so they can do their activities and can maintain relationships that are deemed significant for their social life. The main aim of urban accessibility is to raise the comfort of space for citizens, eliminating all barriers that discriminate people, and prevent from an equality of opportunity. “FIABA FUND - City of ... for the removal of architectural barriers” is an idea of FIABA that has already affected many regions of Italy as Lazio, Lombardy, Campania, Abruzzi and Calabria. It is a National project which provides for opening a bank account in the cities of referring, in which for the first time, all together, individuals and private and public institutions can make a donation to fund initiatives for the removal of architectural barriers within its own territory for a real and effective total accessibility. Last February the fund was launched in Rome with the aim of achieving a Capital without barriers and a Town European model of accessibility and usability. Urban mobility is a prerequisite to access to goods and services, and to organize activities related to daily life. FIABA promotes the concept of sustainable mobility for all, supported by the European Commission’s White Paper. We need a cultural change in management and organization of public means, which might focus on

Full Text Available A 42-day trial was undertaken to study the effect of different dietary levels of thyme essential oil (TEO on serum biochemical indices of broiler chickens. Seven hundred and sixty-eight selected one-day-old Mahua broilers were divided into 8 dietary treatment groups with an addition of 0.00, 0.05, 0.10, 0.15, 0.20, 0.25, 0.30 and 0.35 mg/kg of thyme essential oil respectively, with 4 replicate pens per treatment group (24 birds each. The feeding programme included a starter diet until day 21 and a finisher diet from day 22 until day 42. The results suggested that TEO markedly increased serum total proteins and globulins on day 21, significantly decreased alanine aminotransferase activity (P≤0.05, the albumin- to-globulin ratio, and serum urea on day 21 and 42, and in particular it improved highdensity lipoproteins on day 21 and 42 (P≤0.05. In conclusion, TEO can promote protein metabolism, enhance lipolysis and strengthen the immune function. Furthermore, after a comprehensive analysis, the ideal range of the essential oil addition to the broiler feed proved to be between 0.1 and 0.25 mg/kg.

Rheumatoid factor interference in immunogenicity assays for human monoclonal antibody therapeutics.

Science.gov (United States)

Tatarewicz, Suzanna; Miller, Jill M; Swanson, Steven J; Moxness, Michael S

2010-05-31

Rheumatoid factors (RFs) are endogenous human antibodies that bind to human gamma globulins. RFs demonstrate preferential binding to aggregated gamma globulins and are involved in the clearing mechanism of immune complexes. Immunoassays designed to measure human anti-human antibodies (HAHA) after administration of monoclonal antibody therapeutics are thus vulnerable to interference from RFs. When using a sensitive electrochemiluminescent (ECL) bridging immunoassay, samples from subjects with rheumatoid arthritis demonstrated much higher baseline reactivity than healthy subjects. Interference was found to be dependent on the aggregation state of the therapeutic antibody that had been conjugated with the detection reagent (ruthenium). Size exclusion high performance liquid chromatography (SE-HPLC) demonstrated that of the total integrated peaks, as little as 0.55% high molecular weight aggregates (>600kDa) were sufficient to cause increased reactivity. Stability studies of the ruthenium and biotin conjugated therapeutic antibody indicated that storage time, temperature and buffer formulation were critical in maintaining the integrity of the reagents. Through careful SE-HPLC monitoring we were able to choose appropriate storage and buffer conditions which led to a reduction in the false reactivity rate in therapeutic-naïve serum from a rheumatoid arthritis population.

To ascertain whether tranexamic acid reduces the blood loss and transfusion rate and volumes; increase the prevalence of deep vein thrombosis (DVT); and investigate factors associated with DVT in patients undergoing primary bilateral total knee arthroplasties (TKAs) without use of chemical thromboprophylaxis. There were 874 patients (1748 knees) in the control group who did not receive tranexamic acid and 871 patients (1742 knees) in the study group who received tranexamic acid. Mechanical compression device was applied without any chemical thromboprophylaxis. Transfusion rates and volumes were recorded. DVT was diagnosed using both sonogram and venogram at 7 or 8 day post-operatively. Intra- and post-operative blood loss and transfusion volumes were significantly lower in the tranexamic acid group. The prevalence of DVT was 14% (245 of 1748 knees) in the control group and 18% (314 of 1742 knees) in the tranexamic acid group. Pre- and post-operative perfusion lung scans revealed no evidence of PE in any patients in either group. Coagulation or thrombophilic data or molecular genetic testing was not significantly different between the two groups. The use of tranexamic acid reduces the volume of blood transfusion and does not increase the prevalence of DVT or PE in the patients who did not receive routine chemical thromboprophylaxis after primary bilateral simultaneous sequential TKAs in Asian patients.

Total body irradiation

1987-01-01

The multitude of papers and conferences in recent years on the use of very large megavoltage radiation fields indicates an increased interest in total body, hemibody, and total nodal radiotherapy for various clinical situations. These include high dose total body irradiation (TBI) to destroy the bone marrow and leukemic cells and provide immunosuppression prior to a bone marrow transplant, high dose total lymphoid irradiation (TLI) prior to bone marrow transplantation in severe aplastic anemia, low dose TBI in the treatment of lymphocytic leukemias or lymphomas, and hemibody irradiation (HBI) in the treatment of advanced multiple myeloma. Although accurate provision of a specific dose and the desired degree of dose homogeneity are two of the physicist's major considerations for all radiotherapy techniques, these tasks are even more demanding for large field radiotherapy. Because most large field radiotherapy is done at an extended distance for complex patient geometries, basic dosimetry data measured at the standard distance (isocenter) must be verified or supplemented. This paper discusses some of the special dosimetric problems of large field radiotherapy, with specific examples given of the dosimetry of the TBI program for bone marrow transplant at the authors' hospital

Utilization of total knee and hip arthroplasty has greatly increased in the past decade in the United States; these are among the most expensive procedures in patients with Medicare. Advances in surgical techniques, anesthesia, and care pathways decrease hospital length of stay. We examined how trends in hospital cost were altered by decreases in length of stay. Procedure, demographic, and economic data were collected on 6.4 million admissions for total knee arthroplasty and 2.8 million admissions for total hip arthroplasty from 2002 to 2013 using the National (Nationwide) Inpatient Sample, a component of the Healthcare Cost and Utilization Project. Trends in mean hospital costs and their association with length of stay were estimated using inflation-adjusted, survey-weighted generalized linear regression models, controlling for patient demographic characteristics and comorbidity. From 2002 to 2013, the length of stay decreased from a mean time of 4.06 to 2.97 days for total knee arthroplasty and from 4.06 to 2.75 days for total hip arthroplasty. During the same time period, the mean hospital cost for total knee arthroplasty increased from $14,988 (95% confidence interval [CI], $14,927 to $15,049) in 2002 to $22,837 (95% CI, $22,765 to $22,910) in 2013 (an overall increase of $7,849 or 52.4%). The mean hospital cost for total hip arthroplasty increased from $15,792 (95% CI, $15,706 to $15,878) in 2002 to $23,650 (95% CI, $23,544 to $23,755) in 2013 (an increase of $7,858 or 49.8%). If length of stay were set at the 2002 mean, the growth in cost for total knee arthroplasty would have been 70.8% instead of 52.4% as observed, and the growth in cost for total hip arthroplasty would have been 67.4% instead of 49.8% as observed. Hospital costs for joint replacement increased from 2002 to 2013, but were attenuated by reducing inpatient length of stay. With demographic characteristics showing an upward trend in the utilization of joint arthroplasty, including a shift

The Amerlex Free Thyroxin (T 4 ) Radioimmunoassay Kit (Amersham International Ltd.) is a new direct equilibrium radioimmunoassay for free T 4 based on an antiserum with very high affinity for T 4 , and a unique 125 l-labeled T 4 analog as tracer. It is a very simple single-tube radioimmunoassay, making use of Amerlex particles to separate antibody-bound from free species. Interassay precision (CV) is 3.7% at 13 pmol/L and 2.3% at 30 pmol/L; within-assay precision is 4.2% at 21 pmol/L. The reference interval is 11-22 pmol/L. The assay did not misclassify any patients tested who had untreated myxedema or untreated thyrotoxicosis. The free T 4 assay excelled both the free T 4 index and the T 4 /T 4 -binding globulin ratio in correcting for increased thyroxin-binding globulin from pregnancy, and it was better than the index but not better than the ratio in correcting for increased thyroxin-binding globulin in users of oral contraceptives

Full Text Available Fish has many health benefits but is also the most common source of methylmercury. The bioavailability of methylmercury in fish may be affected by other meal components. In this study, the effect of green tea on the bioavailability of methylmercury from an oral bolus of fish muscle tissue was studied in rats and compared to a water treated control group and a group treated with meso-2,3-dimercaptosuccinic acid (DMSA, a compound used medically to chelate mercury. Rats were given a single oral dose of fish tissue via gavage and one of the treatments. Rats were given access to food for 3 h at 12 h intervals. They were dosed with each of the treatments with each meal. Blood samples were collected for 95 hours. Green tea significantly increased the concentration of total mercury in blood relative to the control, whereas DMSA significantly decreased it. In addition, feeding caused a slight increase in blood mercury for several meals following the initial dose.

Developmental stuttering is known to be a sexually dimorphic and male-biased speech motor control disorder. In the present case-control study, we investigated the relationship between developmental stuttering and steroid hormones. Serum levels of testosterone, dihydrotestosterone (DHT), dehydroepiandrosterone (DHEA), oestradiol, progesterone, cortisol, and sex hormone binding globulin (SHBG), as well as the 2nd/4th digit ratio (2D:4D), an indicator of prenatal testosterone level, were compared between children who stutter (CWS) and children who do not stutter (CWNS). Moreover, two SNPs (CYP17 -34 T:C (MSP AI) and CYP19 T:C (Trp:Arg)) of cytochrome P450, which is involved in steroid metabolism pathways, were analysed between the groups. Our results showed significantly higher levels of testosterone, DHT, and oestradiol in CWS in comparison with CWNS. The severity of stuttering was positively correlated with the serum levels of testosterone, DHEA, and cortisol, whereas no association was seen between the stuttering and digit ratio, progesterone, or SHBG. The CYP17CC genotype was significantly associated with the disorder. Copyright © 2017 Elsevier Inc. All rights reserved.

Greenacre, Cheryl B; Flatland, Bente; Souza, Marcy J; Fry, Michael M

2008-12-01

To compare results of clinical biochemical analysis using an Abaxis VetScan bench-top analyzer with reagents specifically marketed for avian use and a Hitachi 911 analyzer, plasma (both methods) and whole blood (VetScan method) samples from 20 clinically healthy Hispaniolan Amazon parrots (Amazona ventralis) were analyzed. Correlation between methods was very high (r = 0.9-1.0) for aspartate aminotransferase (AST), calcium, glucose, and uric acid; high (r = 0.7-0.89) for creatine kinase (CK), phosphorus, potassium, and total protein; moderate (r = 0.5-0.69) for globulin; and low (r = 0.3-0.49) for albumin and sodium. VetScan analyzer results for globulin, sodium, and uric acid had a constant negative bias (values below those from the Hitachi method). Based on difference plot analysis, results for AST, calcium, CK, and glucose are comparable. Because 16 of 20 values fell below the lower detection limit of the VetScan analyzer, bile acid data were excluded from analysis. By using a relatively small sample size (0.1 ml whole blood or plasma), the VetScan analyzer offers rapid in-house results, compact size, and ease of operation. For 4 of the most clinically relevant biochemical analytes used in avian medicine (AST, calcium, CK, glucose), it offers reliable values. For an additional 4 analytes (phosphorous, potassium, total protein, uric acid), establishing analyzer-specific reference intervals is recommended. Neither the VetScan nor the Hitachi method is recommended to assess albumin and globulin concentrations.

A doubling of microphytobenthos biomass coincides with a tenfold increase in denitrifier and total bacterial abundances in intertidal sediments of a temperate estuary.

Directory of Open Access Journals (Sweden)

Helen Decleyre

Full Text Available Surface sediments are important systems for the removal of anthropogenically derived inorganic nitrogen in estuaries. They are often characterized by the presence of a microphytobenthos (MPB biofilm, which can impact bacterial communities in underlying sediments for example by secretion of extracellular polymeric substances (EPS and competition for nutrients (including nitrogen. Pyrosequencing and qPCR was performed on two intertidal surface sediments of the Westerschelde estuary characterized by a two-fold difference in MPB biomass but no difference in MPB composition. Doubling of MPB biomass was accompanied by a disproportionately (ten-fold increase in total bacterial abundances while, unexpectedly, no difference in general community structure was observed, despite significantly lower bacterial richness and distinct community membership, mostly for non-abundant taxa. Denitrifier abundances corresponded likewise while community structure, both for nirS and nirK denitrifiers, remained unchanged, suggesting that competition with diatoms for nitrate is negligible at concentrations in the investigated sediments (appr. 1 mg/l NO3-. This study indicates that MPB biomass increase has a general, significantly positive effect on total bacterial and denitrifier abundances, with stimulation or inhibition of specific bacterial groups that however do not result in a re-structured community.

Full Text Available This study was conducted to compare the bio-efficacy of herbal methionine (H-Met relative to DL-methionine (DL-Met on 160 “Ross 308” broiler chickens. DL-Met and H-Met were added to the basal diet in eight experimental treatments with three and four concentrations respectively in starter, grower and finisher period. Blood parameters which were measured at 24 and 42 days of age consisted of: serum proteins (total protein, albumin and globulin, serum uric acid, serum fats (low density lipoprotein, high density lipoprotein, triglyceride and cholesterol and serum enzymes (alanine amino transaminase and aspartate amino transaminase. Completely randomized design, multi-exponential and multilinear regressions were used to determine bio-efficacy of H-Met in terms of performance and blood parameters of broilers. The results showed that supplemented methionine (Met sources had no significant effect on blood parameters at 24 day of age. At 42 day of age the amounts of globulin and serum high density lipoprotein (HDL increased with supplemented Met, (p < 0.05. Regression analysis revealed that H-Met was 55.00, 71.00, 78.00, 47.00, 58.00 and 73.00% as efficacious as DL-Met for body weight gain, feed intake, feed conversion ratio, albumin, globulin and high density lipoprotein criteria, respectively. The average of bio-efficacy of H-Met compared to DL-Met was 67.00% and 59.00% on average across performance criteria and blood criteria respectively and was 63.00% across these two criteria tested. The results of the present study indicated that H-Met can be administered as a new and a natural source of Met in poultry industry.

Data were less clear in women, especially across the full adult lifespan, and when segmented by premenopausal and postmenopausal status. 120 healthy women (60 premenopausal and 60 postmenopausal) in Olmsted County, MN, USA, a stable well studied clinical population. Dependent variables: measurements of 10 h fasting high-density lipoprotein cholesterol, total cholesterol, low-density lipoprotein cholesterol, and triglycerides. testosterone, estrone, estradiol, 5-alpha-dihydrotestosterone, and sex-hormone binding globulin (by mass spectrometry); insulin, glucose, and albumin; abdominal visceral, subcutaneous, and total abdominal fat [abdominal visceral fat, subcutaneous fat, total abdominal fat by computerized tomography scan]; and a panel of cytokines (by enzyme-linked immunosorbent assay). Multivariate forward-selection linear-regression analysis was applied constrained to P abdominal visceral fat (P abdominal visceral fat (P abdominal fat and interleukin-8 (P = 2.0 × 10 -5 , 16.9 % of variance; and P = 0.0031, 9.4 % of variance, respectively). Premenopausal vs. postmenopausal comparisons identified specific relationships that were stronger in premenopausal than postmenopausal individuals, and vice versa. Age was a stronger correlate of low-density lipoprotein cholesterol; interleukin-6 of triglycerides and high-density lipoprotein; and both sex-hormone binding globulin and total abdominal fat of non high-density lipoprotein cholesterol in premenopausal than postmenopausal women. Conversely, sex-hormone binding globulin, abdominal visceral fat, interleukin-8, adiponectin were stronger correlates of triglycerides; abdominal visceral fat, and testosterone of high-density lipoprotein cholesterol; and age of both non high-density lipoprotein and low-density lipoprotein in postmenopausal than premenopausal women.

Parathion in technical or formulated form at a sub-lethal dose of 1/20 LD 50 was applied orally or dermally at 2-day interval for three months to determine its effect on RNA, DNA and protein content as well as RNA ase and DNA ase activity in different organs liver, brain and kidneys of adult male albino rats. Also, serum GOT, GPT and ALP activity as well as serum total soluble protein, albumin, globulin, bilirubin and uric acid content were determined in adult male albino rats (Rattus norvegicus). In addition, the present studies were undertaken to investigate different biological activities of the above parameters of black nightshades (Solanum nigrum L) methanolic extract. Two kinds of experimental works were taken off (antioxidants and protective). The results showed that technical and formulated parathion increased RNA and protein content but the content of DNA was insignificantly decreased in all rat organs tissue (liver, brain and kidneys) relative to control. The activity of RNA ase was also stimulated. In case of liver and kidney functions the present data observed that serum GOT, GPT and ALP activity was stimulated but total soluble protein, albumin and globulin content was decreased but the urea, uric acid and bilirubin content of serum was increased. Also, liver lipid peroxidation was elevated significantly either by technical or formulated parathion (ingested orally or induced dermally). It should be noted that formulated parathion ingested orally was the most effective, but the technical one had the lowest toxicity. The results of the present studies showed that crude methanolic extract of black nightshades ripe fruits has a strong antioxidant activity as showed by DPPH, nitric oxide scavenging, total reducing power, Fenton's reaction and total antioxidant capacity assay. Finally the the methanolic extract of the present medicinal plant observed a valuable influence as a protective agent in vivo in serum, liver, brain and kidneys damage of parathion

The present study was aimed to investigate the immunological competence of chlorpyrifos (CPF) insecticide after oral administration in layer chickens. A total of 20 White Leghorn birds were given CPF in drinking water at 0.3 ppm/bird/day (no observable effect level dose) for a period of 3-month. Immune competence status of layer birds and chicks hatched from CPF-treated birds were estimated at 15 days interval in layer birds and monthly interval in chicks using immunological and biochemical parameters. There was a significant decrease in values of total leukocytes count, absolute lymphocyte count, absolute heterophil count, total serum protein, serum albumin, serum globulin, and serum gamma globulin in the birds treated with CPF as compared to control. Similarly, immune competence tests such as lymphocyte stimulation test, oxidative burst assay, and enzyme-linked immunosorbent assay tests indicated lower immunity in birds treated with CPF as compared to control. Subsequently, chicks produced from CPF-treated birds were also examined for immune competence, but no significant difference was observed between chicks of both the groups. The exposure to CPF produced hemo-biochemical and other changes that could be correlated with changes in the immunological profile of layer chickens suggesting total stoppage of using CPF in poultry sheds.

We investigated the radiological and epidemiological data of 4,151 subjects followed up from 1976 to 2003 to determine individual risk factors for hip osteoarthritis (OA), hip pain and/or treatment by total hip replacement (THR). Pelvic radiographs recorded in 1992 were assessed for evidence of hip......-joint degeneration and dysplasia. Sequential body mass index (BMI) measurements from 1976 to 1992, age, exposure to daily lifting and hip dysplasia were entered into logistic regression analyses. The prevalence of hip dysplasia ranged from 5.4% to 12.8% depending on the radiographical index used. Radiological hip OA...

The proximate cause of functional hypothalamic amenorrhea (FHA) is reduced GnRH drive. The concomitant increase in circulating cortisol suggests that psychogenic stress plays an etiologic role, but others have argued for a strictly metabolic cause, such as undernutrition or excessive exercise. Indeed, our finding that the cerebrospinal fluid (CSF) concentration of CRH was not elevated in FHA cast doubt about the extent of hypothalamic-pituitary-adrenal activation in FHA and, therefore, we wondered whether central cortisol levels were elevated. We tested the null hypothesis that CSF cortisol levels would be comparable in FHA and eumenorrheic women (EW). The study is a cross-sectional comparison. The study was set in a general clinical research center at an academic medical center. Fifteen women with FHA who were of normal body weight and 14 EW participated. Blood samples were collected at 15-min intervals for 24 h, followed by procurement of 25 ml CSF. Cortisol, cortisol-binding globulin (CBG), and SHBG levels in blood and CSF were the main outcome measures. CSF cortisol concentrations were 30% greater when serum cortisol was 16% higher in FHA compared with EW. Circulating CBG, but not SHBG, was increased in FHA and, thus, the circulating free cortisol index was similar in FHA and EW. Because CBG and SHBG were nil in CSF, the increase in CSF cortisol in FHA was unbound. The hypothalamic-pituitary-adrenal axis is activated in FHA. The maintenance of CRH drive despite increased CSF cortisol indicates resistance to cortisol feedback inhibition. The mechanisms mediating feedback resistance likely involve altered hippocampal corticosteroid reception and serotonergic and GABAergic neuromodulation.

Induction therapy with a T cell-depleting agent followed by mycophenolate mofetil and tacrolimus is presently the most frequently used immune suppression (IS) regimen in islet transplantation. This study assesses its safety and tolerability in nonuremic type 1 diabetic recipients. Fifty-one patients (age, between 29 and 63 years) with high glycemic variability and problematic hypoglycemia received intraportal islet grafts under anti-thymocyte globulin-mycophenolate mofetil-tacrolimus protocol. They were followed up for over 48 months for function of the implant and adverse events. Severe hypoglycemia and diabetic ketoacidosis were absent in patients with functioning graft. Immune suppressive therapy was maintained for 48 months in 29 recipients with sustained function (group A), whereas 16 patients stopped earlier due to graft failure (group B) and in 6 for other reasons. Group A was significantly older at the time of implantation and achieved higher graft function at posttransplantation month 6 under similar dose of IS. Prevalence of IS-related side effects was similar in groups A and B, occurring predominantly during the first year posttransplantation. IS-related serious adverse events (SAE) were reported in 47% of patients, with 4 presenting with cytomegalovirus infection and 4 (age, 42-59 years) diagnosed with cancer. Except in 1 patient with cancer, all SAEs resolved after appropriate treatment. These risk/benefit data serve as a basis for clinical decision-making before entering an intraportal islet transplantation protocol. A longer benefit is observed in recipients of higher age (≥40 years), but it is not associated with more side effects and SAE.

Three different synthetic chocolate colourant agents (A, B and C) were administered to healthy adult male albino rats for 30 and 60 day periods to evaluate their effects on body weight, blood picture, liver and kidney functions, blood glucose, serum and liver lipids, liver nucleic acids (DNA and RNA), thyroid hormones (T3 and T4) and growth hormone. In addition, histopathological examinations of liver, kidney and stomach sections were studied. These parameters were also investigated 30 days after colourant stoppage (post effect). Ingestion of colourant C (brown HT and indigocarmine) significantly decreased rat body weight, serum cholesterol and HDL-cholesterol fraction, while, T4 hormone, liver RNA content, liver enzymes (S. GOT, S. GPT and alkaline phosphatase), total protein and globulin fractions were significantly elevated. Significant increases were observed in serum total lipids, cholesterol, triglycerides, total protein, globulin and serum transaminases in rats whose diets were supplemented with chocolate colours A and B (sunset yellow, tartrazine, carmoisine and brilliant blue in varying concentrations). Haematological investigations demonstrated selective neutropenia and lymphocytosis with no significant alterations of total white blood cell counts in all rat groups, while haemoglobin concentrations and red blood cell counts were significantly decreased in the rats who were administered food additives A and B. Eosinophilia was noted in rats fed on colourant A only. No changes were recorded for blood glucose, growth hormone and kidney function tests. Histopathological studies showed brown pigment deposition in the portal tracts and Van Küpffer cells of the liver as well as in the interstitial tissue and renal tubular cells of the kidney mainly induced by colourant A. Congested blood vessels and areas of haemorrhage in both liver and renal sections were revealed in those rats who were given colourants B and C. There were no-untoward-effects recorded in the

Experiments were planned to study the radioprotective effect of chlorpromazine (CPZ) and Cysteamine (Cys), when injected separately or combined before irradiation, on some factors affecting the development of rat bone. The results obtained can be summarized as follows: (1) The body weight decreased due to gamma-irradiation. (2) The mortality rate increased after irradiation, but diminished by single or double chemical injection before irradiation. (3) The serum total protein; albumin, globulin contents and A/G ratio were significantly increased, 6 hrs. After irradiation, then declined afterwards. (4) Histochemically, a decrease in bone protein content was demonstrates after irradiation. The above irradiation effects were suppressed by injection of the radioprotective substances. Their effect seems to be cumulative. 4 fig.,3 tab.

The aim of this study was to evaluate the effects of a single high dose of the anti-T-lymphocyte globulin Fresenius (ATG-F), given before kidney transplantation, on the prevention of acute rejection response and infections and on the survival rate of the renal graft and patient. Databases including PubMed, Embase, and the Cochrane Library were searched to identify randomized controlled trials relevant to studying the presurgical use of a single high dose of ATG-F. Five RCTs that included 346 patients were selected. The meta-analysis suggested that the application of ATG-F reduced the postsurgical acute rejection reaction incidence compared to that of the control group (relative risk = 0.50, 95% confidence interval = 0.35-0.71, P = .0001). However, the application of ATG-F exhibited no significant effect on the incidence of urinary tract infection, cytomegalovirus infection, and delayed graft function. Furthermore, the one-year patient survival rate and kidney graft survival rate were not affected. The meta-analysis suggested that the reperfusion use of a single high dose (9 mg/kg) of ATG-F could effectively reduce the incidence of postsurgical acute rejection response without affecting the occurrence of infections, the survival rates of kidney grafts and patients, or the incidence of delayed graft function.

The effect of linseed oil (LO) supplementation on nutrient digestibility, forage (i.e., timothy hay) in sacco ruminal degradation, ruminal fermentation characteristics, protozoal populations, milk production, and milk fatty acid (FA) profile in dairy cows was investigated. Four ruminally cannulated, primiparous lactating cows were used in a 4 × 4 Latin square design (28-d periods). They were fed a total mixed ration (50:50 forage:concentrate (F:C) ratio [dry matter (DM) basis] without supplementation (control, CTL), or supplemented (wt/wt; DM basis) with LO at 2, 3, or 4%. Supplementation with LO had no effect on DM intake (19 kg/d) and apparent total-tract digestibility of nutrients (organic matter, neutral detergent fiber, acid detergent fiber, starch, and gross energy). Ruminal pH, ammonia, and total volatile FA concentrations were not changed by LO supplementation to diets. Extent of changes in volatile FA pattern and effective ruminal degradability of DM of timothy hay were minor. Neither the total numbers nor the genera distribution of protozoa was changed by the addition of increasing amounts of LO to the diet. Milk yield increased linearly (26.1, 27.3, 27.4, and 28.4 kg/d for CTL to LO4, respectively) as the amount of LO added to the diet increased. Milk fat content was not affected by LO supplementation, whereas milk protein content decreased linearly with increasing amounts of LO in the diet. Milk fat proportions of several intermediates of ruminal biohydrogenation of polyunsaturated FA (i.e., trans-10 18:1, trans-11 18:1, cis-9,trans-11 18:2, trans-11,cis-15 18:2, and cis-9,trans-11,cis-15 18:3) increased linearly with LO addition to the diet. The proportion of cis-9,cis-12 18:2 decreased linearly (2.06, 1.99, 1.91, and 1.83% for CTL to LO4, respectively) as the amount of LO in the diet increased. Milk fat content of cis-9,cis-12,cis-15 18:3 increased as the level of LO in the diet increased up to 3% but no further increase was observed when 4% of LO

The purpose of this study was to identify the effect of soy protein based diet on renal and pancreatic disorders in female obese rats. Animals assigned into group I in which 30 rats fed on a balanced diet. Group II contained 30 rats fed on a diet containing 30% fats for 4 weeks. At the end of the 4 th week, one-half of each group was treated as group III which contain 15 rats (half of group I) fed on diet containing 25% soy protein for 3 weeks and represents soy protein group, and the other half served as control. Group IV contained 15 rats (half of group II) fed on a diet containing 25% soy protein for 3 weeks and served as obese + soy protein group, and the other half fed on a normal balanced diet for 3 weeks and represents the obese group. Body weights of rats were recorded every week during the experimental period. Renal and pancreatic functions were measured as urea, creatinine, glomerular filtration rate (creatinine clearance), ammonia, sodium and potassium ions, total protein, albumin, globulin, glucose, insulin and alpha-amylase activity. Feeding with soy protein led to a very high significant increase in urea while creatinine was significantly decreased and creatinine clearance was significantly increased in the groups fed on soy protein. Ammonia concentration was increased in all groups and there was non-significant alteration in sodium and potassium ion concentrations. In soy protein groups (groups III and IV), total protein, albumin and globulin levels were increased. Glucose level was increased in obese rats and significantly decreased in groups III and IV. In group IV, insulin level was decreased which implicated to insulin excess in obesity. Soy protein decreased alpha-amylase activity in groups III and IV as compared to control rats. From these results, soy protein have a direct and protective effect on glomerular disorders and pancreatic secretions. This may be due to isoflavone contents in soy which can modulate the disturbance in metabolism

Full Text Available Fifty-six cats with naturally occurring Babesia felis infection were studied. No breed or sex predilection could be identified, but there was an apparent predilection for young adult cats less than 3 years of age. Macrocytic, hypochromic, regenerative anaemia was present in 57 % of the cats and in-saline agglutination tests were positive in 16 %. No characteristic changes were observed in total or differential leukocyte counts. Thrombocyte counts were variable and thrombocytopaenia was an inconsistent finding. Hepatic cytosol enzyme activity and total bilirubin concentrations were elevated in the majority of cats. Serum protein values were mostly normal, but increased values were occasionally observed and polyclonal gammopathies were observed in all cats with increased total globulin concentrations. No remarkable changes in renal parameters were observed. A variety of electrolyte abnormalities occurred in a number of cats, but no consistent pattern of change could be identified. A close correlation was evident between peripheral and central parasite counts. Concurrent infections with Haemobartonella felis, feline immunodeficiency virus and/or feline leukemia virus were identified in a number of cats.

Full Text Available Aim: An experimental study was conducted on 192-day-old broiler chicks for evaluating the effect of 10% neem leaf extract (NLE supplementationon biochemical parameters in chickens experimentally infected with Escherichia coli O78 at 107 CFU/0.5 ml at 7 days of age. Materials and Methods: The 192-day-old broiler chicks were procured. These chicks were divided into two groups (A and B containing 96 birds each on the 1st day. Diet of all the chicks of Group A was supplemented with 10%NLE in water, whereas chicks of Group B were given feed and water devoid of NLE supplementation throughout the experiment. After rearing for 1 week, chicks of both the groups (A and B were again divided into two subgroups (Group A into A1 and A2 and Group B into B1 and B2 of 54 and 42 birds, respectively. At the age of 7 days all the chicks of groups A1 and B1 were injected with E. coli O78 at 107 CFU/0.5 ml intraperitoneally. Blood samples were collected from six chicks from each group at day 0, 2, 4, 7, 14, 21, 28 days post-infection and serum was separated for biochemical studies. Results: There was a significant increase in serum alanine transaminase (ALT, aspartate transaminase (AST, lactate dehydrogenase (LDH activities, globulin concentration and a decrease in total protein (TP, albumin concentrations, and alkaline phosphatase (ALP activity in both the infected groups. However, the changes in biochemical values, i.e., ALT, AST, LDH, ALP, TP, albumin, and globulin wereof lower magnitude in NLE supplemented group suggesting hepatoprotective and cardioprotective effect of NLE. Conclusions: Fromthe present study, it is reasonable to conclude that significant increase in the value of ALT, AST, LDH, globulin, and significant decrease in the value of ALP, TP, and albumin was of lower magnitude in supplemented infected group (A1 as compared to non-supplemented infected group (B1 suggesting hepatoprotective and cardioprotective effect of NLE.

Increasing access to the intrauterine device (IUD), as part of a comprehensive method mix, is a key strategy for reducing unintended pregnancy and maternal mortality in low-income countries. To expand access to IUDs within the framework of informed choice, Population Services International (PSI) has historically supported increased IUD service delivery through private providers. In applying a total market lens to better understand the family planning market and address major market gaps, PSI identified a lack of high-quality public provision of IUDs. In 2013, PSI started a pilot in 4 countries (Guatemala, Laos, Mali, and Uganda) to grow public-provider IUD service delivery through increased public-sector engagement while maintaining its ongoing focus on private providers. In collaboration with country governments, PSI affiliates carried out family planning market analyses in the 4 pilot countries to identify gaps in IUD service delivery and create sustainable strategies for scaling up IUD services in the public sector. Country-specific interventions to increase service delivery were implemented across all levels of the public health system, including targeted advocacy at the national level to promote government ownership and program sustainability. Mechanisms to ensure government ownership were built into the program design, including a proof-of-concept approach to convince governments of the feasibility and value of taking over and scaling up interventions. In the first 2 years of the pilot (2013-2014), 102,055 IUD services were provided to women at 417 targeted public-sector facilities. These preliminary results suggest that there is untapped demand for IUD service delivery in the public sector that can be met in part through greater participation of the public sector in family planning and IUD provision. © White et al.

Although range of motion (ROM) is considered as an important factor for good outcome after total knee arthroplasty (TKA), the association of the degree of ROM with functional outcome and patient satisfaction is debated. We, therefore, investigated whether increased ROM would affect functional outcome and patient satisfaction after TKA in Asian patients. We reviewed 630 patients who underwent primary TKA with minimum 2-year follow-up. Clinical outcomes were evaluated by Knee Society (KS) score, Western Ontario and McMaster Universities osteoarthritis index, and high-flexion knee score. Patient satisfaction was evaluated using a validated questionnaire. The association of ROM and change in ROM (cROM) with clinical outcomes and satisfaction were analyzed using partial correlation analysis and multiple median regression analysis. All functional scores showed significant correlation with postoperative ROM (r = 0.129, P = .001 in Knee Society score; r = -0.101, P = .012 in Western Ontario and McMaster Universities osteoarthritis index; r = 0.183, P satisfaction (r = 0.192, P = .005). Postoperative ROM and cROM were revealed as predisposing factors affecting function outcome using multivariable regression analysis. cROM was found as a predisposing factor affecting satisfaction. Based on the results of this study, ROM positively associated with functional outcome and cROM positively associated with patient satisfaction after TKA. These findings suggest that increased ROM after TKA is an important factor for functional outcome and satisfaction in Asian patients. Copyright © 2015 Elsevier Inc. All rights reserved.

Automated mobile phone messaging has not been reported in total joint arthroplasty (TJA). Our purpose was to compare Press Ganey (PG) and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores between TJA patients who did and did not receive perioperative automated mobile phone messages. Patients were prospectively enrolled and received messages for 1 week prior until 2 weeks after TJA. Message content included reminders, activity, and pain control. Patients answered select PG/HCAHPS and questions regarding their experience with the automated communication platform. Average PG/HCAHPS scores were compared to historical TJA patients in the 3-year window prior (control group) with significance P communication via automated mobile phone messaging had improved patient satisfaction scores postoperatively. Patients perceived this form of communication was useful and kept them better informed. Automated mobile phone messaging can be an easily integrated, helpful adjunct to surgeons, healthcare systems, and case managers to more effectively communicate with patients undergoing TJA in this era of value-based care.

Stem cell transplantation (SCT) from an unrelated donor (URD) is often considered in patients with severe aplastic anemia (SAA) whom immunosuppressive therapy failed and matched sibling donor is not available. To reduce the incidence of graft-versus-host disease (GVHD) in URD SCT, introducting antithymocyte globulin (ATG) into the conditioning regimen has been proposed. Although ATG was shown to play a role in reducing GVHD in a cohort with diverse hematologic diseases, its role in SAA remains uncertain. The aim of this study was to determine the efficacy and toxicity of ATG in URD SCT for adult patients with SAA. We investigated 83 adult patients with SAA who underwent URD SCT between 2003 and 2014. The transplantation strategy consisted of total body irradiation (total 800 cGy) and cyclophosphamide (total 100 mg/kg to 120 mg/kg), followed by tacrolimus and a short-term methotrexate. We divided patients into 2 groups: group 1 (n = 25), which received HLA-matched (8/8) bone marrow (BM) without ATG, and group 2 (n = 58), which received SCT from either an HLA-mismatched donor or peripheral blood (PB). Thereafter, group 2 was subdivided according to ATG use into group 2A (without ATG, n = 26), which served as a historical cohort, and group 2B (with ATG, n = 32). Rabbit ATG (Thymoglobulin; Genzyme-Sanofi, Lyon, France) was used in group 2B at a dose of 2.5 mg/kg. The median age of all patients was 30 years (range, 17 to 59 years). The incidence of GVHD was significantly lower in group 2B than group 2A, as demonstrated by the rate of grade II to IV acute GVHD at day 100 (31.2% versus 61.5%, P = .003) and the rate of chronic GVHD at 3 years (21.9% versus 65.4%, P = .002). The overall survival rates of the 3 groups were similar. However, GVHD-free, failure-free survival (GFFS) was significantly higher in group 2B than group 2A (P = .034). A multivariable model identified use of ATG as an independent factor affecting grades II to IV acute

Full Text Available Hotel industries are one of the fastest growing areas in India, which is attracting more number of jobs & tourists. This also results in direct impact on Indian economy. All Hotels comprises a higher element of total working cost and they are a good source of income. Hospitality is one of the most important components of hotel industry. To give a good hospitality in hotels to customers, we need to use different machines in different departments. For example if we take section of housekeeping it consists of different sub departments like Rooms & corridors, Toilets, Linen, Furniture and furnishings, Gardens, Public areas etc. In this connection a small implementation of TPM tool called focused improvement & planned maintenance, implemented in alternative usage of electrical systems (energy conservation. Result showed a very significant improvement in energy saving. By adopting Small changes show a significant improvement in the overall system. It also indicates the dire need of proper industrial tools in hotels. Total Productive Maintenance (TPM is one of the pioneering approaches which can be achieved in above said things [1][2].

Rh immune globulin (RhIG) has been used successfully for many years for the antenatal suppression of anti-D in D- mothers carrying D+ babies to prevent hemolytic disease of the fetus and newborn. Although the mechanism of RhIG-induced immunosuppression remains unknown, a recent report (TRANSFUSION 2006;46:1316-22) has shown that women receiving RhIG produce elevated levels of transforming growth factor (TGF)β-1, a powerful immunosuppressant cytokine. It was suggested that induction of TGFβ-1 and immunosuppression may be independent of cognate antigen recognition by RhIG. Herein, we present a description of a mother and baby that supports this hypothesis. Red blood cells and serum were analyzed using saline-tube indirect antiglobulin test methods. RhIG (RhoGAM) was administered after each amniocentesis performed at 28, 31, and 36 weeks' gestation. A group A, D-(cde), K+, Fy(a-b+), MNs, Jk(a+b+) mother with no detectable anti-D had an anti-Fy(a) titer of 4096 before RhIG but only 256 after RhIG. Mother gave birth to a group O, D-(cde), Fy(a+b+) healthy baby boy having a weak-positive direct antiglobulin test with anti-Fy(a) eluted from his cells and the titer in the cord serum was 4. This case demonstrates the potential immunosuppressive properties of RhIG for down regulation of a possible clinically significant alloantibody, not anti-D, where no D+ antigen is in the circulation of the mother. The case illustrates the potential utility for using RhIG to modulate antibody levels in situations other than for classical suppression of anti-D production. Although the mechanism in this case is unknown, TGFβ-1-mediated or antibody-mediated immunosuppression to soluble nonparticulate antigens are possible mechanisms. © 2010 American Association of Blood Banks.

Obesity is frequently associated with complications after total hip arthroplasty (THA) and is often concomitant with malnutrition. The purpose of this study was to investigate the independent morbidity risk of malnutrition relative to obesity. The National Surgical Quality Improvement Program from 2005 to 2013 was queried for elective primary THA cases. Malnutrition was defined as albumin malnutrition with 30-day outcomes. A total of 40,653 THA cases were identified, of which 20,210 (49.7%) had preoperative albumin measurements. Propensity score adjustment successfully reduced potential selection bias, with P > .05 for differences between those with and without albumin data. Malnutrition incidence increased from 2.8% in obese I to 5.7% in obese III patients. With multivariable propensity-adjusted logistic regression, malnutrition was a more robust predictor than any obesity class for any postoperative complication(s) (odds ratio [OR] 1.61, 95% confidence interval [CI] 1.25-2.08), major complications (OR 1.63, 95% CI 1.21-2.19), respiratory complications (OR 2.35, 95% CI 1.27-4.37), blood transfusions (OR 1.71, 95% CI 1.44-2.03), and extended length of stay (OR 1.35, 95% CI 1.14-1.59). Malnutrition incidence increased significantly from obese I to obese III patients and was a stronger and more consistent predictor than obesity of complications after THA.

Full Text Available Analyses of haematological and biochemical constituents were carried out on the Norwegian subspecies of free-ranging red deer (Cervus elaphus atlanticus. All animals were captured from January to March by using a mixture of xylazine and tiletamin-zolazepam. Immobilisation was performed with plastic projectile syringes fired from a dart gun. Fourteen haematological parameters were analysed. There were no differences in the values between hinds and stags and between adults and calves (P > 0.01. Of the 22 biochemical compounds investigated there was a significant difference (P < 0.01 between calves and adults for lactate dehydrogenase (LD, globulin, beta globulin, gamma globulin, and the minerals Na, K, Mg, Zn, Ca, and P. Differences (P < 0.01 between hinds and stags were found in cholesterol, gamma glutamyl transferase (GGT, alpha-1 globulin, alpha-2 globulin and Cu. The blood values determined in this study can be used as reference values for this red deer subspecies immobilised with a mixture of xylazine-tiletamin-zolazepam for health control and diagnosis of diseases.Abstract in Norwegian /Sammendrag:Hematologiske og biokjemiske parametere er analysert på norsk frittlevende hjort (Cervus elaphus atlanticus.

Transforming growth factor-β (TGF-β), interleukin-10 (IL-10), and forkhead box P3 (Foxp3) have important roles in breast cancer development. Previous studies confirmed a correlation between these immune molecules and tumor characteristics, but their association with nutritional status in breast cancer is largely unknown. We aimed to investigate the association between body mass index (BMI), hemoglobin, total protein, albumin, globulin (GLB), albumin/GLB ratio (AGR), pre-albumin, prognostic nutritional index, and TGF-β, IL-10, and Foxp3 mRNA expression in patients with breast cancer. Quantitative real-time PCR was used to detect the mRNA expression of TGF-β, IL-10, and Foxp3 in the peripheral blood of 107 patients with breast cancer and 21 healthy controls. We found that TGF-β mRNA levels were 2.6-fold, 3.2-fold, and 2.3-fold higher in patients with low BMI (BMI (BMI BMI ≥ 25), respectively (P BMI, may strongly affect systematic immune function in patients with breast cancer. © 2018 IUBMB Life, 70(3):237-245, 2018. © 2018 International Union of Biochemistry and Molecular Biology.

This research was conducted in the multilevel marketing industry. Unprofessional salespersons behavior and responsibility can ruin the image of the multilevel marketing industry and distrust to the multilevel marketing industry. This leads to decreased company revenue due to lack of public interest in multilevel marketing products. Seeing these conditions, researcher develop training programs to improve the competence of salespersons in making sales. It was done by looking at factors that affect the level of salespersons sales. The research analyzes several factors that influence the salesperson’s sales level: presentation skills, questioning ability, adaptability, technical knowledge, self-control, interaction involvement, sales environment, and intrapersonal skills. Through the analysis of these factors with One Sample T-Test and Multiple Linear Regression methods, researchers design a training program for salespersons to increase their sales. The developed training for salespersons is basic training and special training and before training was given, salespersons need to be assessed for the effectivity and efficiency reasons.

Four different types of commercial JFET input operational amplifiers were irradiated with ionizing radiation under a variety of test conditions. All experienced significant increases in input offset voltage (Vos). Microprobe measurement of the electrical characteristics of the de-coupled input JFETs demonstrates that the increase in Vos is a result of the mismatch of the degraded JFETs. (authors)

Low acid pepsin treated gamma-globulin was applied to ammonium sulfate salting out method, which was a method to separate bound fraction from free one in radioimmunoassay of steroid hormone, and the effect of the separation and the standard curve were examined. Pepsin treated gamma-globulin was prepared in pH 1.5 to 5.5 and then the pepsin was completely removed. It had an effect to accelerate the precipitation in radioimmunoassay of steroid hormone labelled with 3 H. The effect of pepsin treated gamma-globulin to adhere free steroid hormone and to slat out bound one was compared with that of human gamma-globulin. Pepsin treated gamma-globulin, which was water soluble, could easier reach its optimal concentration, and the separation effect was better than human gamma-globulin. The standard curve of it was steeper, particularly in a small dose, and the reproducibility was also better. It could be applied not only to aldosterone and DOC, but also to the steroid hormones, such as progesterone and DHEA, and it seemed suitable for routine measurement method. (Kanao, N.)

Some biochemical and haematological variables were measured in piglets during the first 48 hours after birth. The piglets were reared either by the sow, or bottle-fed with colostrum (either natural or sterilised by irradiation), or a commercial milk replacer. Mean haemoglobin concentrations, packed cell volumes and erythrocyte counts decreased by approximately 45 per cent in all the groups between birth and 48 hours, but leucocyte counts increased more markedly in the colostrum-fed groups. All the colostrum-fed groups showed rapid increases in serum total protein concentrations which were almost entirely due to increases in gamma globulin concentrations. There was no difference in this respect between natural colostrum and colostrum sterilised by irradiation with 500 Krad of gamma rays. Colostrum sterilised by irradiation can protect piglets against infectious agents and simplify the rearing of piglets under specific pathogen free conditions.

The radical change of lifestyle during Ramadan fast has shown to affect cardiometabolic risk variables in adults. In youth, however, no studies are available. We aimed to evaluate the effect of Ramadan fast on Body Mass Index (BMI) and the cardiometabolic profile of obese adolescents. A prospective cohort study was conducted. We measured weight, height, body composition, blood pressure, heart rate, glucose, insulin, total cholesterol, low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol, triglycerides, and high sensitivity C-reactive protein (hs-CRP) levels before, during the last week of and at 6 weeks after Ramadan. Twenty-five obese adolescents were included. BMI and glucose metabolism did not change after Ramadan or at 6 week after cessation of Ramadan. At the end of Ramadan, a significant decrease in body fat percentage was observed, while significant increases in heart rate, total cholesterol, LDL cholesterol, HDL cholesterol, and hs-CRP were found (all P < 0.05). Six weeks after Ramadan, all parameters returned to baseline levels. In this sample of 25 ethnic obese adolescents transient cardiometabolic changes were observed during Ramadan fasting. Since most of these changes were reversible within 6 weeks, there seems no harm or benefit for obese adolescents to participate in Ramadan.

Full Text Available Aim: The present study was aimed to investigate the immunological competence of chlorpyrifos (CPF insecticide after oral administration in layer chickens. Materials and Methods: A total of 20 White Leghorn birds were given CPF in drinking water at 0.3 ppm/bird/day (no observable effect level dose for a period of 3-month. Immune competence status of layer birds and chicks hatched from CPF-treated birds were estimated at 15 days interval in layer birds and monthly interval in chicks using immunological and biochemical parameters. Results: There was a significant decrease in values of total leukocytes count, absolute lymphocyte count, absolute heterophil count, total serum protein, serum albumin, serum globulin, and serum gamma globulin in the birds treated with CPF as compared to control. Similarly, immune competence tests such as lymphocyte stimulation test, oxidative burst assay, and enzyme-linked immunosorbent assay tests indicated lower immunity in birds treated with CPF as compared to control. Subsequently, chicks produced from CPF-treated birds were also examined for immune competence, but no significant difference was observed between chicks of both the groups. Conclusion: The exposure to CPF produced hemo-biochemical and other changes that could be correlated with changes in the immunological profile of layer chickens suggesting total stoppage of using CPF in poultry sheds.

Full Text Available In the present investigation, an antihyperlipidemic activity of Cladophora koeiei ethanol extract against six pathogenic bacteria was conducted. Also, we evaluate the activity of the alga extract against hyperlipedemia in the administrated albino rates through measuring the blood lipid profiles [triglycerides (TG, total cholesterol (TC, low-density lipoprotein (LDL-C, high-density lipoprotein cholesterol (HDL-C, cholesterol] and induced hepatic damage by measuring the contents of creatinine, total proteins, blood urea nitrogen (BUN, albumin and globulin and diagnostic marker enzymes such as aspartate aminotransaminase (AST and alanine aminotransaminase (ALT. Alga extract proved efficient activity against the tested bacteria ranged between medium and high suppression action. Results revealed also, the efficiency of C. koeiei extract in the decreasing the triglycerides (TG, total cholesterol (TC, low-density lipoproteins (LDL-C, blood urea nitrogen (BUN and creatinine caused by alcohol. However, the treatment by alga extract exhibits high-density of lipoproteins (HDL-C (beneficial, total protein, albumin, and globulins. Also, the algal treatments masking the lethal effects caused by harmful alcohol from raising the rate of enzymes ALT, AST, which returned to the normal state in the groups treated with alga extract. Our findings provide the evidence that new natural antioxidant substances can be present in the C. koeiei extract and hence this alga proves to be effective as a source for therapeutic agents.

Different alcoholic beverages exert different effects on inflammation and oxidative stress but these results are controversial and scanty in some aspects. We analyze the effect of different alcoholic beverages after a fat-enriched diet on lipid profile, inflammatory factors and oxidative stress in healthy people in a controlled environment. We have performed a cross-over design in five different weeks. Sixteen healthy volunteers have received the same oral fat-enriched diet (1486kcal/m(2)) and a daily total amount of 16g/m(2) of alcohol, of different beverages (red wine, vodka, brandy or rum) and equivalent caloric intakes as sugar with water in the control group. We have measured the levels of serum lipids, high sensitivity C-reactive protein (hsCRP), tumor necrosis factor α (TNFα), interleukin 6 (IL-6), soluble phospholipase A2 (sPLA2), lipid peroxidation (LPO) and total antioxidant capacity (TAC). Red wine intake was associated with decreased of mean concentrations of hsCRP, TNFα and IL-6 induced by fat-enriched diet (p<0.05); nevertheless, sPLA2 concentrations were not significantly modified. After a fat-enriched diet added with red wine, TAC increased as compared to the same diet supplemented with rum, brandy, vodka or the control (water with sugar) (p<0.05). Moderate red wine intake, but not other alcoholic beverages, decreased pro-inflammatory factors and increased total antioxidant capacity despite a fat-enriched diet intake in healthy young volunteers.
