    The phenomenon of blood serum atherogenicity was described as the ability of human serum to induce lipid accumulation in cultured cells. The results of recent two-year prospective study in asymptomatic men provided the evidence for association between the changes in serum atherogenicity and dynamics of carotid intima-media thickness progression. The present study was undertaken to test the hypothesis that blood serum atherogenicity and its changes in dynamics may be associated with accumulation of coronary calcium in subclinical atherosclerosis. It was performed in 782 CHD-free participants of The Heinz Nixdorf RECALL (Risk Factors, Evaluation of Coronary Calcium and Lifestyle) Study, in whom blood samples have been taken at the baseline and at the end of 5-year follow-up. Opposite to the previous findings, the changes in serum atherogenicity did not correlate neither with the extent of coronary artery calcification, nor with the changes in Agatston CAC score. There was a moderate but significant rise in serum atherogenicity after 5-year followup period, and the same dynamics was observed for Agatston CAC score, but not for convenient lipid-related risk factors. The absence of association of the changes in serum atherogenicity with the changes in Agatston CAC score, along with previous findings, provides a point of view that serum-induced intracellular cholesterol accumulation is not related to the processes of calcium deposition in arterial wall, since the last one reflects the progression of already existing subclinical atherosclerotic lesions.

  2. Deuterium content variation of human blood serum

    International Nuclear Information System (INIS)

    We report, for the first time, the variation of deuterium content of blood serum of the patients with cancer disease. The tumorous cell, because of the higher growth speed , is deuterium consuming. The deuterium content of blood serum of cancerous human is diminished by about 5-7 ppm compared with that of the healthy individual. This effect is in accordance with some previous results. The replacement of tap water with deuterium depleted water in a drinking water of tumorous mice diminished the growth rate of tumors and the slight increase in the deuterium concentration stimulates growth because it is more easy for the cells to elevate the intracellular deuterium concentration up to the threshold level.

  3. Radioimmunoassay of serum β2-microglobulin in donor's blood

    International Nuclear Information System (INIS)

    Serum β2-microglobulin (β2-MG) was tested by radioimmunoassay in 149 donors' and 54 healthy volunteers' blood. The results were 203 +- 33.0 nmol/l and 176 +- 26.2 nmol/l, respectively. There was significant difference statistically between them (P2-MG content. In order to increase the quality of donated blood and to keep the health of blood donor, it is suggested that the high content of serum β2-MG is the indicator of too frequent blood donating. The results also showed that the content of β2-MG in donor's blood is not a normal reference value

    The effect of freezing regimes and storage temperatures on protein conformation and the spectrum of cord blood serum has been investigated. Changes in the parameters of ESR spectra of spin probes in cord blood serum after slow freezing and subsequent thawing were established, indicating protein conformational changes characterized by loosening. This fact is confirmed by an earlier process, the first stage of albumin heat denaturation, as indicated by calorimetric data. It was shown that slow cooling results in the aggregation of serum protein in which serum albumin and immunoglobulins play an important role. It was concluded that, for retaining the properties, of cord blood serum proteins, it is preferable to perform cooling at a rate not lower than 100 degrees C/min and a storage temperature of -80 degrees C and lower.

    Blood serum samples from 33 red howler monkeys (Alouatta seniculus) were examined. Three different phenotypes were found and denominated A, B, and C. Four serums could not be classified because their transferrin apparently did not bind iron-59, possibly owing to saturation. A difference was observed in the electrophoretic migration and pattern of the transferrins in these monkeys compared with those of other primates. PMID:14197564

    Full Text Available The measurement of lithium in blood serum requires high selectivity since the blood contains about 140 mM sodium compared to the 0.5-1.5 mM lithium level in manic depressive patients under treatment with lithium salts. This review traces the development of optical and potentiometric methods for the selective measurement of lithium in the presence of sodium. Selectivities of over 1,000:1 are achievable with properly designed ionophores.

    Serum vitamin B12 and complete blood count values were determined for 83 volunteer subjects from an American vegetarian society conference (USA). Among subjects who did not supplement their diets with vitamin B12 or multiple vitamin tablets, 92% of the vegans (total vegetarians), 64% of the lactovegetarians, 47% of the lacto-ovovegetarians and 20% of the semivegetarians had serum vitamin B12 levels less than 200 pg/ml (normal = 200-900 pg/ml). However, their complete blood count values did not deviate greatly from those found for nonvegetarians, even though some had been vegans or lactovegetarians for over 10 years. Macrocytosis among the vegetarians was minimal; none had mean corpuscular volume greater than 103 fl.

    Full Text Available Blood serum samples of HYBRO PG broilers were analyzed, with 30 samples collected from 21-day-old broilers (G1, 30 from 35-day-old birds (G2, and 30 from 42-day-old birds (G3, with the aim of establishing normal values of some blood serum parameters. The activities of the enzymes gamma-glutamyl-transferase (GGT, aspartate aminotransferase (AST, creatine kinase (CK, alkaline phosphatase (ALP, and lactate dehydrogenase (LDH, serum levels of total calcium, calcium ion, phosphorus, sodium, potassium, magnesium, chlorides, creatinine, uric acid, triglycerides, cholesterol, total protein, albumin, total and indirect and direct bilirubin, and electrophoretic profile of serum proteins in acrylamide (SDS-PAGE and agarose gel were determined. There was no influence of age on total bilirubin and albumin levels. All the other evaluated parameters presented differences in at least one age group. Protein electrophoretic profile also changed as a function of age. The obtained results can be considered as normal for the studied ages, and therefore be used as references for the interpretation of laboratory exams of broilers of this genetic line in the evaluated ages.

    Chemical cross-linking combined with mass spectrometry has proven useful for studying protein-protein interactions and protein structure, however the low density of cross-link data has so far precluded its use in determining structures de novo. Cross-linking density has been typically limited by the chemical selectivity of the standard cross-linking reagents that are commonly used for protein cross-linking. We have implemented the use of a heterobifunctional cross-linking reagent, sulfosuccinimidyl 4,4'-azipentanoate (sulfo-SDA), combining a traditional sulfo-N-hydroxysuccinimide (sulfo-NHS) ester and a UV photoactivatable diazirine group. This diazirine yields a highly reactive and promiscuous carbene species, the net result being a greatly increased number of cross-links compared with homobifunctional, NHS-based cross-linkers. We present a novel methodology that combines the use of this high density photo-cross-linking data with conformational space search to investigate the structure of human serum albumin domains, from purified samples, and in its native environment, human blood serum. Our approach is able to determine human serum albumin domain structures with good accuracy: root-mean-square deviation to crystal structure are 2.8/5.6/2.9 Å (purified samples) and 4.5/5.9/4.8Å (serum samples) for domains A/B/C for the first selected structure; 2.5/4.9/2.9 Å (purified samples) and 3.5/5.2/3.8 Å (serum samples) for the best out of top five selected structures. Our proof-of-concept study on human serum albumin demonstrates initial potential of our approach for determining the structures of more proteins in the complex biological contexts in which they function and which they may require for correct folding. Data are available via ProteomeXchange with identifier PXD001692.

  10. Ratio of blood serum ferritin and ferritin-bearing lymphocytes in breast cancer

    International Nuclear Information System (INIS)

    The ratio of the blood serum ferritin level and the amount of ferritin-bearing lymphocytes was determined in breast cancer patients and mastopathy patients. Direct relation between a rise of blood serum ferritin concentration, a drop in the amount of ferritin-bearing cells and tumor spreading was established in breast cancer. The maximum amount of ferritin-bearing cells was present in the blood of the patients with Stage I-IIA disease. Radical mastectomy in such patients returned the blood serum ferritin level and the amount of ferritin-bearing cells to normal

    We compared the cultivation of human peripheral blood lymphocytes in serum-free medium Hybris-2 and RPMI 1640 medium with 10% fetal bovine serum in the presence of phytohemagglutinin and interleukin-2. The optimal concentration of phytohemagglutinin significantly differed in serum-free and serum-containing media (0.5 and 5 microg/ml, [corrected] respectively). Both mitogens were more potent in stimulating the proliferation of lymphocytes in serum-free medium than in serum-containing medium. Strong proliferation of CD3(+) and CD4(+) T lymphocytes was observed in both media. The dynamics of other markers was similar in serum-free and serum-containing media. However, significant differences were revealed between individual donors. Our results indicate that the developed serum-free medium may be used in lymphocyte cultivation for scientific, diagnostic, and therapeutic purposes.

    Data on coffee consumption were collected for 1074 adults attending for health checks in the OXCHECK study, to assess associations with serum lipids and blood pressure. Of the sample, 70.5% drank coffee, largely instant. Coffee had no significant effects on total or high-density lipoprotein (HDL) cholesterol or blood pressure, and was negatively correlated with serum triglycerides. The type of coffee drunk in the UK does not adversely effect these cardiovascular risk factors.

    The water proton relaxation rate constant R1 = 1/ T1 (at 60 MHz) of blood serum is substantially increased by the presence of free Cu 2+ ions at concentrations above normal physiological levels. Addition of chelating agents to serum containing paramagnetic Cu 2+ nulls this effect. This was demonstrated by looking at the effect of adding a chelating agent—D-penicillamine (D-PEN) to CuSO 4 and CuCl 2 aqueous solutions as well as to rabbit blood serum. We propose that the measurement of water proton spin-lattice relaxation rate constants before and after chelation may be used as an alternative approach for monitoring the presence of free copper ions in blood serum. This method may be used in the diagnosis of some diseases (leukaemia, liver diseases and particularly Wilson's disease) because, in contrast to conventional methods like spectrophotometry which records the total number of both bound and free ions, the proton relaxation technique is sensitive solely to free paramagnetic ions dissolved in blood serum. The change in R1 upon chelation was found to be less than 0.06 s -1 for serum from healthy subjects but greater than 0.06 s -1 for serum from untreated Wilson's patients.

  17. Optical diagnosis of dengue virus infection in human blood serum using Raman spectroscopy

    International Nuclear Information System (INIS)

    We present the optical diagnosis of dengue virus infection in human blood serum using Raman spectroscopy. Raman spectra were acquired from 18 blood serum samples using a laser at 532 nm as the excitation source. A multivariate regression model based on partial least-squares regression is developed that uses Raman spectra to predict dengue infection with leave-one-sample-out cross validation. The prediction of dengue infection by our model yields correlation coefficient r2 values of 0.9998 between the predicted and reference clinical results. The model was tested for six unknown human blood sera and found to be 100% accurate in accordance with the clinical results. (letter)

    Elevated serum levels of uric acid consistently correlate with hypertension, but the directionality of the association remains debated. To help define this relationship, we used a controlled setting within a homogeneous Amish community and the Mendelian randomization of a nonsynonymous coding single-nucleotide polymorphism, rs16890979 (Val253Ile), in the SLC2A9 gene. This gene expresses the GLUT9 transporter that also transports uric acid and is associated with lower serum uric acid levels. We studied the unconfounded association between genotype and blood pressure in 516 Amish adults, each placed for 6 days on standardized diets, first with high sodium, followed by low sodium, with an intervening washout period. Blood pressure, measured using 24-h ambulatory monitoring, during both diet periods was used as the primary outcome. All participants were free of diuretic or other antihypertensive medications and the relationships between GLUT9 genotype and both serum uric acid and blood pressure were assessed. Each copy of the GLUT9 minor Ile allele was found to confer a significant 0.44 mg/dl reduction in serum uric acid and was associated with a significant mean decrease in the systolic blood pressure of 2.2 and 1.5 mm Hg on the high- and low-sodium diet, respectively. Thus, a Mendelian randomization analysis using variants in the GLUT9 gene indicates that a decrease in serum uric acid has a causal effect of lowering blood pressure. PMID:22189840

    Body weight, fasting blood glucose (GP) (BFG), serum immunoreactive insulin (IRI), serum growth hormone (GH) and serum glycosylated proteins were longitudinally followed in 2 groups of women during two years' oral contraception. One group (n = 10) received a combination of 0.030 mg ethinylestradiol and 0.150 mg levonorgestrel and the other (n = 10) a combination of 0.030 mg ethinylestradiol and 0.150 mg of desogestrel. There was a significant increase in BFG during the study and the values were still rising, when examined 2 months after discontinuation of the pill. Two subjects, reaching the level of 5.5 mmol/l showed normal pretreatment values, when investigated one year later. After 6 months' use of either preparation, GH significantly increased, remained on that level throughout the study and returned to the pretreatment level after discontinuation of the pill. Body weight, IRI and GPP did not change significantly during the study.

    2016-05-01

    In this study we generated a simple, reliable and selective approach based on carbon dots (CDs) and 4-cyanophenylboronic acid (CPBA) for blood glucose sensing. The methodology relies on the quenching of the emission of CDs by CPBA followed by its recovery by glucose. The system consisting of CDs and CPBA was characterised by Fourier transform infra red spectrum, transmissions electron microscopic, dynamic light scattering instrument, UV–visible and fluorescence techniques. The response of the probe, CD-BA in presence of different concentrations of glucose was assessed. Linear range was obtained for glucose concentrations ranging from 1 to 30 mM. Interferences by other saccharides and various biomolecules coexisting in blood serum were negligible. The chemo sensor thus developed has been successfully used for the estimation of glucose in human blood serum. The system being sensitive, efficient and easy to perform is a promising platform for blood glucose sensing.

    1993-01-01

    A liquid chromatographic method was developed for the analysis of indandione and 4-hydroxycoumarin anticoagulant rodenticides in blood serum and liver. The method enabled the measurement of serum and liver concentrations of eight anticoagulant rodenticides: brodifacoum, bromadiolone, chlorophacinone, coumafuryl, coumatetralyl, diphacinone, difenacoum, and warfarin. Anticoagulants were extracted from serum and liver with acetonitrile. Extracts were applied to solid-phase extraction columns, which contained mixed packings. Column eluates were evaporated to dryness, reconstituted, and subjected to reversed-phase liquid chromatography. Hydroxycoumarins were detected by fluorescence at an excitation wavelength of 318 nm and an emission wavelength of 390 nm. Indandiones were detected by UV absorption at 285 nm. Extraction efficiencies of greater than 75% for serum and greater than 69% for liver were obtained. The within-run precision (CV) ranged from 2.4 to 8.6% for serum and 2.6 to 8.7% for liver. The between-run precision (CV) ranged from 1.5 to 12.2% for serum and from 2.1 to 11.8% for liver. Hydroxycoumarin rodenticides were detected at 1 ng/mL of serum and 1 ng/g of liver. Indandiones were detected at 10 ng/mL of serum and 10 ng/g of liver. PMID:8429630

    Full Text Available Background and Objectives. There is no data analyzing the outcome of blood transfusions and oral iron therapy in patients with kidneys failure in sub-Saharan Africa. The present study aimed to fill that gap and assess the value of ferritin in the diagnosis of iron overload and deficiency. Design. From January to February 2012, we prospectively studied 85 hemodialysis patients (78% of males and 22% of females aged 20 to 79 years attending the Gabonese National Hemodialysis Centre. Results. Correlation studies showed (a a strong positive linear relationship between the number of blood transfusions and high serum ferritin in hemodialysis patient (Spearman r:0.74; P value: 0.0001; (b a weak association between the number of blood transfusions and serum iron concentrations (Spearman r:0.32; P value: 0.04; (c a weak association between serum ferritin and serum iron (Spearman r:0.32; P value: 0.003. Also, the strength of agreement beyond chance between the levels of ferritin and iron in the serum was poor (κ=0.14. The prevalence of iron overload was 10.6%, whereas the prevalence of iron deficiency was 2.3%, comparing (1 patients with a maximum of one transfusion not on iron therapy; (2 patients with a maximum of one transfusion on iron therapy; (3 polytransfused patients not on iron therapy; and (4 polytransfused patients on oral iron therapy. The “Kruskal-Wallis test” showed that ferritin levels varied significantly between the groups (P value: 0.0001. Conclusion. Serum ferritin is not reliable as a marker of iron overload. For patients undergoing regular transfusion we recommend routine serum ferritin measurement and yearly measurement of LIC.

    1991-01-01

    A sensitive liquid chromatographic method was developed for the analysis of 4-hydroxycoumarin anticoagulant rodenticides in blood serum. The method can simultaneously measure the serum levels of five anticoagulant rodenticides: brodifacoum, bromadiolone, coumatetralyl, difenacoum, and warfarin. Serum proteins are precipitated with acetonitrile and the supernatant is mixed with ethyl ether. The organic phase is separated, evaporated to dryness, and the residue subjected to chromatographic analysis. The anticoagulants are separated by reversed-phase gradient chromatography with fluorescence detection at an excitation wavelength of 318 nm and emission wavelength of 390 nm. Extraction efficiencies of 68.1 to 98.2% were obtained. The within-run precision (CV) ranged from 2.19 to 3.79% and the between-run precision (CV) from 3.72 to 9.57%. The anticoagulants can be quantitated at serum levels of 10 to 20 ng/mL. PMID:1943055

    Full Text Available In a herd of high-productive dairy cows of the Holstein breed, 40 cows were selected for an experiment. The animals were chosen at the period of advanced gravidity. Data on mean values of beta-carotene concentrations in blood serum of the cows show that significantly higher values (p<0.01 were established in advanced gravidity (x=9.53± 3.49 μmol/l in comparison with the values on calving day (x=5.69±3.14 μmol/l and in early puerperium (x=2.25±1.00 μmol/l. The average concentration of vitamin A in blood serum of cows varied approximately the same as the concentration of beta-carotene. The highest average concentration of vitamin A in blood serum of cows was determined in advanced gravidity (x=1.856±0.52 μmol/l, and the lowest in early puerperium (x=0.988±0.31 μmol/l (p<0.05. It can be concluded on the grounds of the results obtained in this work that the average concentration of beta-carotene and vitamin A in blood serum of cows in advanced gravidity and on the day of calving is within the limits of physiological values and in keeping with the values cited in literature, and that concentrations of beta-carotene and vitamin A in blood serum of cows two weeks after calving are significantly lower than the values obtained in advanced gravidity and on the day of calving and are lower than the physiological values most often reported in literature for this animal specie.

    Full Text Available Several epidemiologic studies have reported that exposure to noise is associated with cardiovascular disease. The increased body weight is often associated with metabolic as well as increased blood pressure. The aim of this study is to investigate the correlation between the elevation of blood pressure and serum leptin hormones due to the effects of noise in the work place. A total of 80 volunteer males where included in this study with an age range between of 20 and 45 years, they were divided in two groups equally, the 1 st group were exposed to noise in the workplace while the 2 nd group were not. The individual noise exposure was determined by using a sound level meter. The range of noise was 80-100 dBA. Body Mass Index was also taken for each individual by a standard measure, blood pressure was measured by OMRON sphygmomanometer and serum leptin was measured through venous blood sample analysis enzyme linked immunosorbent assay. Spearman rank order correlation was used to examine the correlations between Blood pressure value (Systolic, Diastolic and Leptin. All the relationships between parameters showed a positive correlation. Systolic and diastolic blood pressure values had a significant correlation to leptin hormone level in comparison to the control. There was a significant relation between leptin and blood pressure. leptin effects on the sympathetic nervous system may provide a partial explanation. Therefore, Leptin might have diverse cardiovascular actions.

  8. Identification of transferrin as the principal neptunium-binding protein in the blood serum of rats

    Wirth, R.; Taylor, D.M.; Duffield, J.

    1985-01-01

    The binding of 239Np(V) to blood serum components of rats was examined in vivo and in vitro. After gel filtration of the serum using a Sephacryl S-300 column, 98% of the applied activity appeared with protein fractions representing coeluted albumins and transferrin. A separation of the albumin- and transferrin-proteins by ion-exchange chromatography using DEAE-cellulose showed the 239Np being entirely bound to the iron-carrier protein transferrin. The high elution yields from the ion-exchange columns, greater than 90%, suggest that the binding may be quite strong. The binding capacity of transferrin for neptunium in vivo was found to decline when the iron level in blood serum was increased. Precipitation experiments showed that 84 +/- 2% of the 239Np was precipitated with 10% (w/v) trichloracetic acid, 77 +/- 3% with 90% ethanol but only 6 +/- 1% with saturated ammonium sulphate at pH 7.4. The available data indicate that as for plutonium, thorium, americium and curium, the iron transport protein, transferrin, may be the main carrier protein for neptunium in mammalian blood serum.

    In vitro generation of artificial red blood cells (RBCs) is very important to overcome insufficient and unsafe blood supply.

    In vitro generation of artificial red blood cells (RBCs) is very important to overcome insufficient and unsafe blood supply. Despite recent progresses in RBCs engineering from several stem cell sources, none of them could succeed in generation of functional RBCs in the absence of serum/plasma and feeder cells. Without the elimination of serum and plasma, human RBC engineering in a large scale is impossible, especially for the future bioreactor system.

    AIM:The healthy ranges for serum alanine aminotransferase (ALT) levels are less well studied. The aim of this study was to define the upper limit of normal (ULN) for serum ALT levels, and to assess factors associated with serum ALT activity in apparently healthy blood donors.METHODS: A total of 1 939 blood donors were included.ALT measurements were performed for all cases using the same laboratory method. Healthy ranges for ALT levels were computed from the population at the lowest risk for liver disease. Univariate and multivariate analyses were performed to evaluate associations between clinical factors and ALT levels.RESULTS: Serum ALT activity was independently associated with body mass index (BMI) and male gender, but not associated with age. Association of ALT with BMI was more prominent in males than in females. Upper limit of normal for non-overweight women (BMI of less than 25) was 34 U/L,and for non-overweight men was 40 U/L.CONCLUSION: Serum ALT is strongly associated with sex and BMI. The normal range of ALT should be defined for male and female separately.

    To appraise the national blood requirement and supply, and to determine the impact of alanine aminotransferase (ALT) and hepatitis B surface antigen (HBsAg) screening on the blood supply, 407 random blood donor sera were tested for HBsAg, human immunodeficiency virus (HIV), and ALT activity. HBsAg and anti-HIV antibody were determined by the enzyme linked immunosorbent assay (ELISA) technique using Hepanostica and Welcozyme kits, respectively. The Western Blot test was performed to confirm anti-HIV positive sera by the ELISA technique. ALT was determined by an automated photometer using ALAT kits and serologic testing for syphilis was done by the rapid plasma reagin (RPR) test. The amount of blood required in Ethiopia and the actual supply was calculated on the basis of the number and type of hospital beds in Addis Abeba and the amount of blood transfusions in units per hospital bed. The results showed that the combined donor and unit rejection rate was 34.6%. The annual blood requirement was 7 units for emergency and 4 units for nonemergency beds. The national blood requirement in 1989 was 64,350-80,000 units, but the supply met only a third of the requirement. The mean and 2SD cut off ALT levels were 28 and 69 IU/L, respectively. ALT was elevated in 9.1% of HBsAg positive but apparently healthy donors, while HBsAg screening eliminated 25% of those with elevated ALT activity. This data suggests that there is a serious blood shortage in Ethiopia and that the currently supplied blood is relatively unsafe in terms of hepatitis.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1659534

  13. Direct determination of sodium and potassium in blood serum by flow injection and atomic absorption spectrophotometry

    International Nuclear Information System (INIS)

    A simple and reliable method for the measurement of sodium and potassium in blood serum without any sample dilution by using flow injection and atomic absorption spectrophotometry is described. A sample throughout of 100 measurements per hour is possible. The coefficient of variation for within-run determination was about 1,14 and 2,36% for sodium and potassium, respectively, in serum samples (n=10). The method is easily adaptable to pediatric research, because of the low required sample volume of 5ul. (Author)

    International Nuclear Information System (INIS)

    Objective: To investigate the change of serum cortisol levels and its correlation to blood sugar and serum insulin levels in patients with type 2 diabetes mellitus. Methods: Blood sugar with oxidase method and serum cortisol insulin levels with RIA (8 AM fasting specimen) were measured in 26 patients with type 2 diabetes mellitus and 30 controls. Results: The serum cortisol levels in the diabetic patients were significantly higher than those in the controls (P<0.01). The cortisol levels were positively correlated to the blood sugar levels (r=0.32, p<0.01), but not correlated to insulin levels. Conclusion: There were cortisol secretion disturbances in patients with type 2 diabetes

    Aedes aegypti is the major vector of dengue, yellow fever and chikungunya viruses that put millions of people in endemic countries at risk. Mass rearing of this mosquito is crucial for strategies that use modified insects to reduce vector populations and transmission of pathogens, such as sterile insect technique or population replacement. A major problem for vector mosquito mass rearing is the requirement of vertebrate blood for egg production since it poses significant costs as well as potential health hazards. Also, regulations for human and animal use as blood source can pose a significant obstacle. A completely artificial diet that supports egg production in vector mosquitoes can solve this problem. In this study, we compared different blood fractions, serum and red blood cells, as dietary protein sources for mosquito egg production. We also tested artificial diets made from commercially available blood proteins (bovine serum albumin (BSA) and hemoglobin). We found that Ae. aegypti performed vitellogenesis and produced eggs when given whole bovine blood, serum, or an artificial diet containing BSA. Conversely, egg production was impaired after feeding of the red blood cell fraction or an artificial diet containing only hemoglobin. We also found that egg viability of serum-fed mosquitoes were comparable to that of whole blood and an iron supplemented BSA meal produced more viable eggs than a meal containing BSA alone. Our results indicate that serum proteins, not hemoglobin, may replace vertebrate blood in artificial diets for mass mosquito rearing. PMID:26020000

    Full Text Available Background: Emphysema is associated with high incidence of morbidity and mortality. The imbalance between oxidants and antioxidants is thought to play an important role in the pathogenesis of Emphysema. Methods: A total number of 80 subjects comprising of 40 healthy controls and 40 Emphysema cases were studied. In all the subjects, serum levels of malondialdehyde (MDA as a biomarker of lipid peroxidation and antioxidant whole blood reduced glutathione (GSH were estimated. Results: The level of whole blood reduced glutathione was significantly decreased in emphysema patients when compared to controls. Serum MDA was significantly increased in Emphysema patients when compared to controls. Conclusion: The presence of increased systemic oxidative stress in emphysema patients seems to be associated with current active smoking and systemic inflammation. The decrease in antioxidants levels appears to be mainly a consequence of increased oxidative stress. This suggests that oxidative stress is likely to be involved in pathogenesis of emphysema.

    Colorectal cancer (CRC) is the third most common cancer in men and women in the United States. Raman Molecular Imaging (RMI) is an effective technique to evaluate human tissue, cells and bodily fluids, including blood serum for disease diagnosis. ChemImage Corporation, in collaboration with clinicians, has been engaged in development of an in vitro diagnostic Raman assay focused on CRC detection. The Raman Assay for Colorectal Cancer (RACC) exploits the high specificity of Raman imaging to distinguish diseased from normal dried blood serum droplets without additional reagents. Pilot Study results from testing of hundreds of biobank patient samples have demonstrated that RACC detects CRC with high sensitivity and specificity. However, expanded clinical trials, which are ongoing, are revealing a host of important preanalytical considerations associated with sample collection, sample storage and stability, sample shipping, sample preparation and sample interferents, which impact detection performance. Results from recent clinical studies will be presented.

    This is the first investigation into the content of autoantibodies to a glycolipid antigen (AG) marker of oligodendroglial and myelin membranes, and to galactocerebrosides, in the blood serum of children with neuroinfections. High titres of these antibodies were shown in most cases of meningitis, encephalitis, meningoencephalomyelitis. High titres can persist for a long time. The data suggest that oligodendroglial and myelin structures are involved into the pathology and that autosensitization to nervous tissue is developing.

    Full Text Available The human body is constantly under attack from free radicals that occur as part of normal cell metabolism, and by exposure to environmental factors such as UV light, cigarette smoke, environmental pollutants and gamma radiation. The resulting “Reactive Oxygen Species” (ROS circulate freely in the body with access to all organs and tissues, which can have serious repercussions throughout the body. The body possesses a number of mechanisms both to control the production of ROS and to cope with free radicals in order to limit or repair damage to tissues. Overproduction of ROS or insufficient defense mechanisms leads to a dangerous disbalance in the organism. Thereby several pathomechanisms implicated in over 100 human diseases, e.g., cardiovascular disease, cancer, diabetes mellitus, physiological disease, aging, etc., can be induced. Thus, a detailed investigation on the quantity of oxygen radicals, such as hydroxyl radicals (OH● in human serum blood, and its possible correlation with antioxidant therapy effects, is highly topical. The subject of this study was the influence of schizophrenia on the amount of OH● in human serum blood. The radicals were detected by fluorimetry, using terephthalic acid as a chemical trap. For all experiments the serum blood of healthy people was used as a control group.

    Full Text Available Monoclonal gammopathy of undetermined significance (MGUS is a premalignant proliferative disorder that may progress to multiple myeloma, a malignant plasma cell neoplasia. We evaluated differential scanning calorimetry (DSC as an experimental tool for differentiating serum samples of MGUS patients from healthy individuals. DSC thermograms can be used for monitoring changes in the serum proteome associated with MGUS. MGUS patients showed great variability in serum thermogram characteristics, which depended on the IgG, IgA or IgM isotypes and/or the κ or λ light chains. Thermogram feature parameters distinguished patients with MGUS from healthy people. Serum samples, named as non-MGUS, were also collected from patients with subjacent immunological pathologies who were discarded of having MGUS through serum immunofixation. They were used to verify the sensitivity of DSC for discriminating MGUS from related blood dyscrasias. Only some DSC thermogram feature parameters differentiated, to a lesser extent, between MGUS and non-MGUS individuals. We contemplate DSC as a tool for early diagnosis and monitoring of MGUS.

    Over the last 10-15 years, γ-hydroxybutyrate (GHB) and γ-butyrolactone have become increasingly popular "club drugs", but they have also gained attention as potential agents of drug-facilitated sexual assault (DFSA). Several studies have attempted to characterize GHB's pharmacokinetic properties in humans, and the aim of this paper is to build on this research with an emphasis on DFSA cases. A 25 mg/kg dose of GHB was given to 12 GHB-naïve volunteers (6 men and 6 women). Urine and blood samples (serum and whole blood) were collected and analyzed by gas chromatography-mass spectrometry following liquid-liquid extraction. The urinary T(max) was 1 h in 11 volunteers with a mean C(max) of 67.6 mg/L (32.6-161.3 mg/L). Urinary concentrations rapidly decreased to GHB is distributed into erythrocytes. All 12 volunteers had GHB concentrations of less than 5 mg/L in both whole blood and serum after 3 h. Results verify the rapid elimination of GHB and the limited retrospective power of a concentration-based approach to prove GHB administration in blood and urine and confirm that, in DFSA cases, samples should be collected as soon as possible.

  10. Synthesis of fluorine-18 radio-labeled serum albumins for PET blood pool imaging

    International Nuclear Information System (INIS)

    We sought to develop a practical, reproducible and clinically translatable method of radiolabeling serum albumins with fluorine-18 for use as a PET blood pool imaging agent in animals and man. Fluorine-18 radiolabeled fluoronicotinic acid-2,3,5,6-tetrafluorophenyl ester, [18F]F-Py-TFP was prepared first by the reaction of its quaternary ammonium triflate precursor with [18F]tetrabutylammonium fluoride ([18F]TBAF) according to a previously published method for peptides, with minor modifications. The incubation of [18F]F-Py-TFP with rat serum albumin (RSA) in phosphate buffer (pH 9) for 15 min at 37–40 °C produced fluorine-18-radiolabeled RSA and the product was purified using a mini-PD MiniTrap G-25 column. The overall radiochemical yield of the reaction was 18–35% (n = 30, uncorrected) in a 90-min synthesis. This procedure, repeated with human serum albumin (HSA), yielded similar results. Fluorine-18-radiolabeled RSA demonstrated prolonged blood retention (biological half-life of 4.8 hours) in healthy awake rats. The distribution of major organ radioactivity remained relatively unchanged during the 4 hour observation periods either by direct tissue counting or by dynamic PET whole-body imaging except for a gradual accumulation of labeled metabolic products in the bladder. This manual method for synthesizing radiolabeled serum albumins uses fluorine-18, a widely available PET radionuclide, and natural protein available in both pure and recombinant forms which could be scaled up for widespread clinical applications. These preclinical biodistribution and PET imaging results indicate that [18F]RSA is an effective blood pool imaging agent in rats and might, as [18F]HSA, prove similarly useful as a clinical imaging agent

    Some risk factors associated with coronary heart disease (CHD) were evaluated in patients with different types of anorexia nervosa (AN). Anthropometric parameters, serum cholesterol, triglycerides and apoprotein (apo) B values, blood pressure and pulse rate were tested in 29 young female patients and 16 controls. Cholesterol, triglycerides and apo B were higher at the acute period of the illness (AN1), whereas at the chronic period the values of these parameters tended to normalize. Triglycerides were higher in patients who binge ate (bulimarexia). Systolic blood pressure decreased in all types of AN, while diastolic blood pressure decreased only in AN1; pulse rate was not altered. According to cholesterol and apo B values, AN patients may be at risk of CHD if they remain at low body weight. PMID:1855497

    The interaction between two serum blood proteins, namely human serum albumin (HSA) and human immunoglobulin G (IgG), with 1,2-dimyristoyl-sn-glycero-3-phosphatidylcholine (DMPC) liposomes has been studied in detail using dynamic light scattering, flow cytometry, enzyme-linked immunosorbent assay (ELISA), electrophoretic mobility, differential scanning calorimetry (DSC), and surface tension measurements. HSA and IgG interact with liposomes forming molecular aggregates that remain stable at protein concentrations beyond those of total liposome coverage. Both HSA and IgG penetrate into the liposome bilayer. An ELISA assay indicates that the Fc region of IgG is the one that is immersed in the DMPC membrane. The liposome-protein interaction is mainly of electrostatic nature, but an important hydrophobic contribution is also present.

  17. Analysis of blood serum of lung cancer patients using particle induced X-ray emission

    International Nuclear Information System (INIS)

    Trace elemental imbalance in human beings is postulated to exert action, directly or indirectly, on the carcinogenic process. The objective of this study was to evaluate the levels of trace elements in blood serum samples of lung cancer patients and analyze their alteration with respect to healthy controls. Particle induced X-ray emission (PIXE), a well established method for elemental analysis, was used to identify and quantify trace elements in the blood serum samples of the studied groups. The PIXE measurements were carried out using 2.5 MeV collimated proton beam from the 3 MV Tandem Pelletron Accelerator at Ion Beam Laboratory, Institute of Physics, Bhubaneswar, India. The serum of the cancerous group displayed increased concentrations of Ti, Ni, and Cu but lowered concentrations of V, Cr, Mn, Fe, Co, Zn, and Se. Statistically significant differences were found for serum Cr (p < 0.01), Fe (p < 0.0005), Ni (p < 0.05), Cu (p < 0.00005), and Zn (p < 0.0005) between the two studied groups. The copper to zinc ratio for the lung cancer group was 2.24 ± 0.39, which was almost three times the value for normal subjects (0.77 ± 0.14). The observed alterations are discussed with respect to the possible mechanisms by which these elements might influence the carcinogenic process. Significant reduction in mortality from lung cancer can be achieved by advances in early diagnosis and implementation of multidisciplinary treatment programmes leading to improvement of survivorship and better quality of life. It is expected that similar studies from all corners of the world would ultimately lead to the development of novel therapeutic agents to treat lung cancer. (author)

    Full Text Available Background & aim: The decrease of serum glucose level and lipids in diabetic patients is clinically significant. The purpose of this study was to determine the effect of Commiphora mukul extract on blood sugar and lipid profile in diabetic rats. Methods: In the present experimental study, thirty-two male Wistar rats were randomly divided into four groups: control, control treated with the extract, diabetic and diabetic treated with the extract. Diabetes was induced by intraperitoneal injection of Streptozotocin. In an eight week period, the control group of normal saline and the control group and diabetic recipient extract of CM oleo gum blue resin was given by gavage. Treatment resumed eight weeks with onset of hyperglycemia. The control and diabetic control groups received normal saline orally. Extract treated control and extract treated diabetic groups received extract of Commiphora mukul gum (300 mg/kg P.O. daily by gavage. At the end of this period, blood samples were collected from each rat and biochemical tests for investigation of glucose level and lipid profile was performed. One- way analysis of variance (ANOVA statistical test and Post-hoc test Tukey’s were used for data analysis Results: The study indicated that diabetes increases the serum levels of glucose, cholesterol, triglycerides, LDL and HDL. Administration of Commiphora mukul gum extract in diabetic groups significantly decreased the serum level of glucose, cholesterol(p<0.01 and triglyceride and LDL(p<0.001 and increased HDL(p<0.01. Conclusion: Commiphora mukul gum extract may well improve undesirable effects of diabetes on serum level of glucose, cholesterol, triglyceride, LDL and HDL.

    The microchip technology represents convenient and relatively economic tool of analyzing specific biomarkers with the purpose to diagnose diseases, to evaluate effectiveness of therapy and to investigate signaling pathways. To analyze protein composition of blood serum certain types of finished microchips which were not applied previously on the territory of Russia. The detection from 2% to 5% out of matrix of chips depending on their variety was managed without preliminary depletion of serum (removal of proteins of major fractions). Hence, partial protein composition of blood serum can be analyzed with microchips even without preliminary removal of proteins of major fractions.

    Boudewijn Klop

    Full Text Available INTRODUCTION: Erythrocytes carry apolipoprotein B on their membrane, but the determining factors of erythrocyte-bound apolipoprotein B (ery-apoB are unknown. We aimed to explore the determinants of ery-apoB to gain more insight into potential mechanisms. METHODS: Subjects with and without CVD were included (N = 398. Ery-apoB was measured on fresh whole blood samples using flow cytometry. Subjects with ery-apoB levels ≤ 0.20 a.u. were considered deficient. Carotid intima media thickness (CIMT was determined as a measure of (subclinical atherosclerosis. RESULTS: Mean ery-apoB value was 23.2% lower in subjects with increased CIMT (0.80 ± 0.09 mm, N = 140 compared to subjects with a normal CIMT (0.57 ± 0.08 mm, N = 258 (P = 0.007, adjusted P<0.001. CIMT and ery-apoB were inversely correlated (Spearman's r: -0.116, P = 0.021. A total of 55 subjects (13.6% were considered ery-apoB deficient, which was associated with a medical history of CVD (OR: 1.86, 95% CI 1.04-3.33; adjusted OR: 1.55; 95% CI 0.85-2.82. Discontinuation of statins in 54 subjects did not influence ery-apoB values despite a 58.4% increase in serum apolipoprotein B. Subjects with blood group O had significantly higher ery-apoB values (1.56 ± 0.94 a.u. when compared to subjects with blood group A (0.89 ± 1.15 a.u, blood group B (0.73 ± 0.1.12 a.u. or blood group AB (0.69 ± 0.69 a.u. (P-ANOVA = 0.002. CONCLUSION: Absence or very low values of ery-apoB are associated with clinical and subclinical atherosclerosis. While serum apolipoprotein B is not associated with ery-apoB, the ABO blood group seems to be a significant determinant.

    In the present work, metallomics studies using biomolecular (matrix-assisted laser desorption ionization time-of-flight tandem mass spectrometry, MALDI-TOF MS/MS) and elemental mass spectrometry (laser ablation inductively coupled plasma mass spectrometry, LA-ICPMS) of human blood serum samples from bipolar disorder (BD) patients compared to controls were performed. The serum samples from three different groups: control (n = 25), BD patients treated with Li (n = 15), and BD patients not treated with Li (n = 10), were pooled according to their groups and separated by two-dimensional polyacrylamide gel electrophoresis (2-D PAGE). Then, in order to determine the metals bound to the protein spots and search for differences among the studied groups, the 2-D gels were analyzed by LA-ICPMS in three distinct modes: bioimaging of metals in gel sections, line scan through the protein spots, and microlocal analysis of selected protein spots. MALDI-TOF MS/MS characterized 32 serum proteins, and they were associated with the metals previously detected. When comparing control and treated BD patient groups, a differentiation in terms of metals bound to proteins was possible to observe. The main metals bound to proteins found in all groups were Na, Mg, Zn, Ca, and Fe. Mn was only detected in the control group; Co was only observed in the control and BD patients treated with Li group. K and Ti were only found in the BD patient groups, and P was only observed in control and BD patients not treated with Li drugs. This exploratory work shows that the association of LA-ICPMS with MALDI-TOF MS/MS is a powerful strategy in metallomics studies applied to determine differences in metal-containing proteins, being able to play an important role on the discovery of potential markers for BD and its treatment with Li in serum samples.

    Full Text Available Introduction. Aim of this study was the training effect evaluation on the Special Aviation Gymnastics Instruments (SAGI on blood metallothionein (MT, zinc (Zn, copper (Cu, protein, neuron-specific enolase (NSE, and physical fitness in the examined cadets. Material and methods. The study comprised 55 cadets, aged 20, divided into two groups: examined group A (N=41 and control group B (N=14. In both groups, blood material was collected twice, i.e. before (baseline and after training (series I, during (series II, and after completion of training on the SAGI (Series III. Blood serum MT, Zn, Cu, protein, and NSE were assayed with commercially available kits. Physical fitness was assessed with commonly used fitness tests. Results. A significant decrease in serum MT was noted in both groups in all three series of assays after training, except group B in series II. NSE significantly increased in group A in series II after training. NSE activity increased significantly in group B in series I and III. In both groups, a significant decrease in blood serum Zn was noted after training in series I and II. Serum Cu significantly decreased in group A in all three series of assays. Blood serum protein significantly decreased in group A in series III. In series II, blood serum protein increased significantly in both groups. The remaining values were not changed significantly. Conclusions. Training intensity on SAGI lowered serum MT levels after training in comparison with the control group. This might be associated with Zn, Cu, and protein metabolism.

    Full Text Available Despite observational evidence from epidemiological and clinical studies associating sex hormones with various cardiometabolic risk factors or diseases, pathophysiological explanations are sparse to date. To reveal putative functional insights, we analyzed associations between sex hormone levels and whole blood gene expression profiles.We used data of 991 individuals from the population-based Study of Health in Pomerania (SHIP-TREND with whole blood gene expression levels determined by array-based transcriptional profiling and serum concentrations of total testosterone (TT, sex hormone-binding globulin (SHBG, free testosterone (free T, dehydroepiandrosterone sulfate (DHEAS, androstenedione (AD, estradiol (E2, and estrone (E1 measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS and immunoassay. Associations between sex hormone concentrations and gene expression profiles were analyzed using sex-specific regression models adjusted for age, body mass index, and technical covariables.In men, positive correlations were detected between AD and DDIT4 mRNA levels, as well as between SHBG and the mRNA levels of RPIA, RIOK3, GYPB, BPGM, and RAB2B. No additional significant associations were observed.Besides the associations between AD and DDIT4 expression and SHBG and the transcript levels of RPIA, RIOK3, GYPB, BPGM, and RAB2B, the present study did not indicate any association between sex hormone concentrations and whole blood gene expression profiles in men and women from the general population.

    2010-01-01

    Full Text Available Levels of IgM autoantibodies (AAbs to native (double-stranded and denaturated (single-stranded DNA were studied in blood serum of sixty patients with hemorrhagic fever with renal syndrome (HFRS and twenty-five healthy persons, using an ELISA technique. The median levels of IgM AAbs to double-stranded DNA in blood serum of healthy persons and HFRS patients corresponded to 0.41 and 0.53 arbitrary units, respectively. Thus, the difference between the samples from HFRS and healthy persons proved to be non-significant. The median level of IgM AAbs to single-stranded DNA in blood sera of HFRS patients (0.71 arbitrary units did significantly exceed serum values of healthy persons (0.57 arbitrary units. A probable involvement of IgM AAbs into regulation of IgG AAbs' production during virus-induced activation of autoimmune events in HFRS patients is discussed.

    End-stage liver disease (ESLD) is life-threatening and liver transplantation (LTx) is the definitive treatment with good outcomes. Given the essential role of hepatocytes in Cu homeostasis, the potential of the serum Cu isotopic composition for monitoring a patient’s condition post-LTx was evaluated. For this purpose, high-precision Cu isotopic analysis of blood serum of ESLD patients pre- and post-LTx was accomplished via multi-collector ICP-mass spectrometry (MC-ICP-MS). The Cu isotopic composition of the ESLD patients was fractionated in favour of the lighter isotope (by about ‑0.50‰). Post-LTx, a generalized normalization of the Cu isotopic composition was observed for the patients with normal liver function, while it remained light when this condition was not reached. A strong decrease in the δ65Cu value a longer term post-LTx seems to indicate the recurrence of liver failure or cancer. The observed trend in favour of the heavier Cu isotopic composition post-LTx seems to be related with the restored biosynthetic capacity of the liver, the restored hepatic metabolism and/or the restored biliary secretion pathways. Thus, Cu isotopic analysis could be a valuable tool for the follow-up of liver transplant patients and for establishing the potential recurrence of liver failure.

    Luminescent porous silicon nanoparticles (PSiNPs) have been widely used as drug delivery. However, fast biodegradation and short blood circulation have been major challenges for their biomedical applications. Herein, bovine serum albumin was readily encapsulated onto alkyl-terminated PSiNPs surfaces via hydrophobic interaction, which could significantly improve their water-dispersibility and long-term stability under physiological conditions. Furthermore, compared with PSiNPs alone, PSiNPs coated with bovine serum albumin remarkably reduced nonspecific cellular uptake in vitro and prolonged blood circulation in vivo.

    A new diagnostic approach based on Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectrometry and classification algorithm has been introduced which provides a rapid, reliable, and easy way to perform blood test for the diagnosis of renal failure. Blood serum samples from 35 renal failure patients and 40 healthy persons were analyzed by ATR-FTIR spectrometry. The resulting data was processed by Quadratic Discriminant Analysis (QDA) and QDA combined with simple filtered method. Spectroscopic studies were performed in 900-2000 cm-1 spectral region with 3.85 cm-1 data space. Results showed 93.33% and 100% of accuracy for QDA and filter-QDA models, respectively. In the first step, 30 samples were applied to construct the model. In order to modify the capability of QDA in prediction of test samples, filter-based feature selection methods were applied. It was found that the filtered spectra coupled with QDA could correctly predict the test samples in most of the cases.

    Introduction: Historically, serum alanine transaminase (ALT) has been used as a surrogate marker in the detection of hepatitis viruses in blood donors. With the availability of newer sensitive technologies for the detection of seroconversion, the value of ALT becomes questionable but continues to be used for this purpose with subsequent discarding of ALT elevated blood units. Objective: The present study aims to evaluate the significance and cost effectiveness of ALT as a surrogate marker for...

    AIM: To determine serum γ-glutamyltransferase (GGT), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) activity, and to assess their correlation with demographic and clinical findings in healthy blood donors.METHODS: This cross-sectional study was performed in 934 male blood donors, aged 18 to 68 years, who consecutively attended Tehran blood transfusion service in 2006. All participants were seronegative for HBV or HCV infections, non alcohol users, and all underwent a standard interview and anthropometric tests. Clinical and biochemical parameters including AST, ALT, and GGT activities were determined. Patients taking drugs known to cause hepatic fat deposition were excluded. For AST, ALT, and GGT variables, we used 33.33 and 66.66 percentiles, so that each of them was divided into three tertiles.RESULTS: Mean AST, ALT, and GGT activities were 25.26 ± 12.58 U/L (normal range 5-35 U/L), 33.13 ± 22.98 (normal range 5-35 U/L), and 25.11 ± 18.32 (normal range 6-37 U/L), respectively. By univariate analyses, there were significant associations between increasing AST, ALT, or GGT tertiles and age, body weight, body mass index, and waist and hip circumferences (P < 0.05). By multiple linear regression analyses, ALT was found to be positively correlated with dyslipidemia (B = 6.988, P = 0.038), whereas ALT and AST were negatively correlated with age. AST, ALT, and GGT levels had positive correlation with family history of liver disease (B = 15.763, P < 0.001), (B = 32.345, P < 0.001), (B =24.415, P < 0.001), respectively.CONCLUSION: Although we did not determine the cutoffs of the upper normal limits for AST, ALT, and GGT levels, we would suggest screening asymptomatic patients with dyslipidemia and also subjects with a family history of liver disease.

    Full Text Available The influence of different copper and zinc contents in rations on blood serum concentrations in dependence on feeding (Groups A and B and lactation (Lactation 1 and 2 was tested in a feeding trial with 60 German Holstein cows. All animals received a diet based on maize and grass silage ad libitum. 30 cows received a concentrate supplemented with copper and zinc as recommended (Group A, whereas the other 30 animals were offered a concentrate with roughly double the amount of copper and zinc (Group B. Blood samples were taken several times during the lactation to analyse serum concentrations of copper and zinc. Copper serum concentration was influenced neither by the different feeding (11.7 mol/L in Group A and 12.3 mol/L in Group B nor by the lactation (12.0 mol/L in Lactation 1 and 12.1 mol/L in Lactation 2. Zinc serum concentration was significantly influenced as well as by feeding (14.1 mol/L in Group B and 12.5 mol/L in Group A and lactation (14.2 mol/L in the second lactation and 12.8 mol/L for first lactating cows. For an exact diagnosis of trace element supply, blood serum is a not qualified indicator; other sources (feedstuffs, liver, hair must also be investigated.

    We developed a radioimmunoassay with a gamma-emitting radioligand to measure androstenedione in human serum and in dried blood-spot samples from newborns. Antisera were raised in rabbits against androstenedione linked to bovine serum albumin at positions 3, 6, or 11 on the steroid nucleus. Radioligands were prepared by linking ({sup 125}I)iodohistamine at positions 3, 6, or 11. Linkages were through either carboxymethyloxime or hemisuccinate bridges. All label and antibody combinations were examined, and the most sensitive and specific combination (antiserum raised against androstenedione-3-carboxymethyloxime-bovine serum albumin with an androstenedione-carboxymethyloxime-({sup 125}I)iodohistamine label) was selected for full evaluation. We report the performance of these selected reagents in an immunoassay for androstenedione in both serum and dried blood-spot samples from neonates. We measured concentrations of androstenedione in serum under normal and pathological conditions such as congenital adrenal hyperplasia and polycystic ovarian disease. Diurnal variation in normal men was observed. Androstenedione was measured in blood spots from neonates born at term or prematurely, with respiratory distress syndrome, or with congenital adrenal hyperplasia.

    To investigate hematological and serum protein profiles of cadaveric heart blood with regard to the cause of death, serial forensic autopsy cases (n=308, >18 years of age, within 48 h postmortem) were examined. Red blood cells (Rbc), hemoglobin (Hb), platelets (Plt), white blood cells (Wbc), total protein (TP) and albumin (Alb) were examined in bilateral cardiac blood. Blood cell counts, collected after turning the bodies at autopsy, approximated to the clinical values. Postmortem changes were not significant for these markers. In non-head blunt injury cases, Rbc counts, Hb, TP and Alb levels in bilateral cardiac blood were lower in subacute deaths (survival time, 1-12 h) than in acute deaths (survival time blood were significantly higher for non-head injury than for head injury in subacute deaths. In fire fatality cases, Plt count was markedly higher with an automated hematology analyzer than by using a blood smear test, suggesting Rbc fragmentation caused by deep burns, while increases in Wbc count and decreases in Alb levels were seen for subacute deaths. For asphyxiation, Rbc count, Hb, TP and Alb levels in bilateral cardiac blood were higher than other groups, and TP and Alb levels in the right cardiac blood were higher for hanging than for strangulation. These findings suggest that analyses of blood cells and proteins are useful for investigating the cause of death.

  14. Arterial blood pressure but not serum albumin concentration correlates with ADC ratio values in pediatric posterior reversible encephalopathy syndrome

    International Nuclear Information System (INIS)

    Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological entity affecting both adults and children characterized by neurotoxicity often in setting of hypertension coupled with distinct brain magnetic resonance imaging features. Decreased serum albumin level has been suggested to correlate with the presence of vasogenic brain edema in adult PRES. Serum albumin has thus been hypothesized to protect against neurotoxicity in PRES by reducing vasogenic brain edema through its role in maintaining plasma osmotic pressure and endothelial integrity. The purpose of our study was to investigate if such correlation between decreased serum albumin level and PRES-related vasogenic edema could be found in children. We conducted a retrospective study of 25 pediatric patients diagnosed with PRES. Underlying clinical conditions, presenting symptoms, blood pressures, and serum albumin levels at onset of symptoms were collected. Brain MR imaging studies were reviewed. We used a quantitative method to evaluate the degree of vasogenic edema by measuring apparent diffusion coefficient (ADC) values of the T2-FLAIR hyperintense brain lesions. No significant correlation was found between serum albumin level and degree of PRES-related vasogenic edema. A significant correlation was found between elevated blood pressure and degree of vasogenic edema in the temporal lobes (p = 0.02 and 0.04, respectively) but not in the other cerebral lobes or cerebellum. Our initial results suggest blood pressure, not serum albumin level, as a main biomarker for brain edema in children with PRES. Thus, our study does not suggest a protective role of serum albumin against PRES-related neurotoxicity in children. (orig.)

    Objective:To explore the relationship between levels of blood glucose, blood lipid and serum cystatin C and lower-extremity arterial disease in type 2 diabetic mellitus so as to provide the basis for the prevention and treatment of the disease.Methods:A total of 240 cases of patients with type 2 diabetic mellitus receiving physical examinations in our hospital from March 2014 to March 2015 were selected and divided into three groups. The control group was consisted of type 2 diabetes patients without lower-extremity arterial disease, the observation group 1 included type 2 diabetes patients with mild or moderate lower-extremity arterial disease, and the observation group 2 was formed by type 2 diabetes patients with severe lower-extremity arterial disease. Each group contained 80 cases. Then, the heights, weights, waist and hip circumferences of patients in the three groups were determined and the body mass index (BMI) and waist to hip ratio (WHR) were calculated; the fasting blood glucose (FBG), fasting insulin (FINS), insulin resistance index (HOMA-IR), 2 h postprandial blood glucose (2 h PG) and glycosylated hemoglobin (HBA1c) in two groups were detected; and the levels of serum total cholesterol(TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), apolipoprotein A1 (apoA1), apolipoprotein B (apoB) and cystatin C (CysC) in two groups were also tested.Results:Compared with the control group, the WHR, FBG, HOMA-IR, 2 h PG, HBA1c, LDL-C, apoB and CysC all increased significantly, and the differences were statistically significant. Besides, there were statistically significances existing between the observation groups 1 and 2. What’s more, the serum levels of TC, HDL-C, TG and apoA1 in the observation groups were not significantly different from those of the control group.Conclusions: There is a close relationship between blood glucose, blood lipid, serum cystatin C level and lower-extremity arterial

    Background Hypertension is a very important cause of morbidity and mortality. Serum gamma-glutamyl transpeptidase (GGT) is a biomarker of oxidative stress and associated with increased risk of hypertension and diabetes. The aim of this study was to evaluate the association of serum GGT level, which is an early marker of inflammation and endothelial dysfunction, with the deterioration of the diurnal rhythm of the blood pressure. Methods A total of 171 patients with hypertension were included in this study. Patients whose nighttime mean blood pressure, measured via ambulatory blood pressure monitoring, decreased between 10% and 20% compared with the daytime mean blood pressure were defined as “dippers”, whereas patients with a nighttime blood pressure decrease lower than 10% were defined as “non-dippers”. Results A total of 99 hypertensive patients (65 females/34 males) were classified as dippers and 72 patients (48 females/24 males) as non-dippers. The mean age of the non-dipper group was significantly greater than the dipper group. Serum GGT, C-reactive protein and uric acid levels were significantly higher among patients in the non-dipper group. Negative correlations were detected between GGT levels and diurnal systolic and diastolic blood pressure decreases. Conclusion Our findings revealed that GGT level was higher in the non-dipper group, and was negatively correlated with the nighttime decrease of diurnal blood pressure. C-reactive protein and uric acid levels were also higher in the non-dipper group. However, future randomized controlled prospective studies with larger patient populations are necessary to confirm our findings. PMID:27660457

    In this study, some heavy metal (Cd, Pb, Ni, Fe, Co, Cr, Mn, Cu, and Zn) concentrations were measured in the blood serum samples of 25 patients who suffered from the multiple sclerosis (MS) disease living in two industrial regions of Isfahan, Iran, using inductively coupled plasma (ICP) instrument. Also, blood serum levels of heavy metals in 25 healthy people of Isfahan and 25 healthy people of Shiraz were analyzed as controls. In industrial regions, some of the heavy metals were also measured in the soils and food crop samples (wheat, rice, and onion). The results showed that the blood serum levels of Cd, Co, Ni, and Pb of MS patients (0.032, 0.56, 1.60, and 2.90 μg L(-1), respectively) were significantly higher than those of healthy people. These values exceeded the permissible ranges that are 0.08-0.50, 0.14-1.0, and 0.80-2.50 μg L(-1) for the Co, Ni, and Pb, respectively. The mean concentrations of Fe and Zn in the blood serum of MS patients (529 and 547 μg L(-1)) were significantly lower than those in the healthy people and also less than the acceptable ranges (700-1700 and 660-1100 μg L(-1), respectively). The target hazard quotients of Pb (2.23) and Cd (1.25) via wheat and Pb (1.34) via rice consumption were higher than one. Therefore, it is proposed that consumption of local contaminated food crops may have drastically increased the concentrations of heavy metals in the human blood serum of inhabitants of industrial regions.

    Genalyte has developed a multiplex silicon photonic chip diagnostics platform (MaverickTM) for rapid detection of up to 32 biological analytes from a drop of sample in just 10 to 20 minutes. The chips are manufactured with waveguides adjacent to ring resonators, and probed with a continuously variable wavelength laser. A shift in the resonant wavelength as mass binds above the ring resonators is measured and is directly proportional to the amount of bound macromolecules. We present here the ability to multiplex the detection of hemorrhagic fever antigens in whole blood, serum, and saliva in a 16 minute assay. Our proof of concept testing of a multiplex antigencapture chip has the ability to detect Zaire Ebola (ZEBOV) recombinant soluble glycoprotein (rsGP), Marburg virus (MARV) Angola recombinant glycoprotein (rGP) and dengue nonstructural protein I (NS1). In parallel, detection of 2 malaria antigens has proven successful, but has yet to be incorporated into multiplex with the others. Each assay performs with sensitivity ranging from 1.6 ng/ml to 39 ng/ml depending on the antigen detected, and with minimal cross-reactivity.

    Full Text Available The aim of the research was to study the relation between blood haemoglobin (Hb and serum iron (Fe concentrations and changing of heart girth with age in calves. Blood samples of 66 dairy calves were taken at the age of 3, 5 and 16 weeks (wks. Blood samples were analysed for Hb and serum Fe concentration. At each bleeding, the heart girth was measured. The lowest mean concentration of Hb was measured at the age of five wks. The concentration of serum Fe and heart girth increased with age. Significant positive correlations were found between Fe concentration at 3 wks of age and heart girth of calves at 5wks (r=0.270; P=0.032 and between Fe concentration at 5 wks and heart girth of calves at 5 (r=0.283; P=0.021 and 16 wks (r=0.284; P=0.028. The lowest Hb concentration recorded at 5 wks, might suggest that this is the most critical period for developing anaemia in calves. The correlations established between heart girth and Fe concentration at different ages indicate that serum Fe concentration has some influence on changing of heart girth in calves.

    Full Text Available The paper presents the results of investigations of the presence of the bovine herpesvirus-1 (BHV-1 in samples of blood serum from 106 cows and 107 of their calves (one cow had twins. Blood was sampled from the cows immediately after parturition, and from the calves before feeding on colostrum. The examined cows and their calves originated from 5 herds in which previous investigations had shown infection with the bovine herpesvirus-1. The determination of antibodies against BHV-1 was performed using the method of virus neutralization in culture of MDBK cells with 100 TCID/50 viruses (BHV-1, TN-41 Am. Bio Research, USA. Antibodies against BHV-1 were determined in all blood serum samples of cows and in 16 samples of precolostral blood serums of calves. The antibody titer values in cows ranged from 1:4 to 1:512, and in calves the determined values were from 1:2 to 1:16. The results indicate that cows that are seropositive to BHV-1 can deliver calves seropositive to BHV-1 in about 15% cases. This must be kept in mind in selecting cows for the production of breeding material, in particular bulls for reproduction centers, as well as in making a programme for the immunoprophylaxis of calves against BHV-1. .

This polymorphism detection was based on whole blood DNA extraction. Alternatively, DNA for genetic diagnosis has been derived from buccal epithelial cells (BEC, dried blood spots (DBS, and genomic DNA from serum. The aim of the study was to investigate the reliability and accuracy of alternative routes of testing for single nucleotide polymorphism allele rs12979860CC. METHODS: Blood, plasma, and sera samples from 200 patients were extracted (400 µL. Buccal smears were tested using an FTA card. To simulate postal delay, we tested the influence of storage at ambient temperature on the different sources of DNA at five time points (baseline, 48 h, 6 days, 9 days, and 12 days. RESULTS: There was 100% concordance between blood, plasma, sera, and BEC, validating the use of DNA extracted from BEC collected on cytology brushes for genetic testing. Genetic variations in HPTR1 gene were detected using smear technique in blood smear (3620 copies as well as in buccal smears (5870 copies. These results are similar to those for whole blood diluted at 1/10. A minimum of 0.04 µL, 4 µL, and 40 µL was necessary to obtain exploitable results respectively for whole blood, sera, and plasma. No significant variation between each time point was observed for the different sources of DNA. IL28B SNPs analysis at these different time points showed the same results using the four sources of DNA. CONCLUSION: We demonstrated that genomic DNA extraction from buccal cells, small amounts of serum, and dried blood spots is an alternative to DNA extracted from peripheral blood cells and is helpful in retrospective and prospective studies for multiple genetic markers, specifically in hard-to-reach individuals.

    Serum cortisol and total protein levels, blood pressure, heart rate, lung volume, and reaction time were studied in 52 males 20-25 years of age practicing Dhammakaya Buddhist meditation, and in 30 males of the same age group not practicing meditation. It was found that after meditation, serum cortisol levels were significantly reduced, serum total protein level significantly increased, and systolic pressure, diastolic pressure and pulse rate significantly reduced. Vital capacity, tidal volume and maximal voluntary ventilation were significantly lower after meditation than before. There were also significant decreases in reaction time after mediation practice. The percentage decrease in reaction time during meditation was 22%, while in subjects untrained in meditation, the percentage decrease was only 7%. Results from these studies indicate that practising Dhammakaya Buddhist meditation produces biochemical and physiological changes and reduces the reaction time. PMID:1801007

    Sensitive and fast detection of antibiotic residues in animal derived foods and blood serum is of great interest. In this study a fluorescent aptasensor was designed for selective and sensitive detection of streptomycin (STR) based on Exonuclease III (Exo III), SYBR Gold and aptamer complimentary strand. In the absence of STR, the fluorescence intensity is weak. Upon addition of STR, the aptamer binds to its target, leading to release of complementary strand from aptamer and more protection against Exo III function. Following addition of SYBR Gold, a strong fluorescence intensity is obtained. This aptasensor showed a high selectivity toward STR with a limit of detection (LOD) as low as 54.5 nM. The validity of the procedure and applicability of the aptasensor were successfully assessed by detection of STR in a spiked milk and blood serum without interference from the sample matrix.

  15. Studies on Some Biophysical Properties of the Serum Protein of Mice blood exposed to an electric field

    International Nuclear Information System (INIS)

    As an indication of the effect of the electric field on each of the dielectric properties and the molecular structure of the serum protein of the mice blood, an electric field of a 6 kv/m strength and 50 Hz frequency was directed to three groups of mice for exposure periods 30, 45 and 60 days respectively, and investigated directly. Another group was exposed to also 60 days, but investigated after 30 days from switching off the electric field for delayed effect studies. The molecular structure of the serum protein was studied by measuring each of the dielectric relaxation and the electric conductivity in the frequency range 0.15 MHz at 4 ± 0.5 degree C and the dielectric increment (Δ), relaxation time (τ) and average molecular radii (τ) were calculated for all groups. The absorption spectra of the extracted protein were also measured in the wavelength range 200 600 nm. Moreover, electrophoresis of enzymes B-esterase, lactate and Malate dehydrogenase extracted from the blood serum of exposed mice were taken by using the gel electrophoresis technique. The results indicated that exposure of the animals to 50 H, 6 kv/m electric field resulted in the decrease of serum protein permittivity values and increase its conductivity a fact that indicates pronounced changes in the molecular structure of total serum protein the exposed mice. In addition, the intensity of the absorption spectral bands of serum protein of exposed mice were found to decrease relative to unexposed mice. Also the enzymes B-esterase and lactate dehydrogenase were slightly affected by exposing to the electric field whereas their number of bands and their intensities changed relative to the unexposed mice but the malate dehydrogenase was not affected

    Creatine kinase (CK: adenosine-5-triphosphate-creatine phosphotransferase) is an important enzyme of muscle cells; the presence of a large amount of the enzyme in blood serum is a biomarker of muscular injuries, such as acute myocardial infarction. This work describes a bi-enzyme (glucose oxidase and hexokinase based) biosensor for rapid and convenient determination of CK activity by measuring the rate of ATP production by this enzyme. Simultaneously the biosensor determines glucose concentration in the sample. Platinum disk electrodes were used as amperometric transducers. Glucose oxidase and hexokinase were co-immobilized via cross-linking with BSA by glutaraldehyde and served as a biorecognition element of the biosensor. The biosensor work at different concentrations of CK substrates (ADP and creatine phosphate) was investigated; optimal concentration of ADP was 1mM, and creatine phosphate - 10 mM. The reproducibility of the biosensor responses to glucose, ATP and CK during a day was tested (relative standard deviation of 15 responses to glucose was 2%, to ATP - 6%, to CK - 7-18% depending on concentration of the CK). Total time of CK analysis was 10 min. The measurements of creatine kinase in blood serum samples were carried out (at 20-fold sample dilution). Twentyfold dilution of serum samples was chosen as optimal for CK determination. The biosensor could distinguish healthy and ill people and evaluate the level of CK increase. Thus, the biosensor can be used as a test-system for CK analysis in blood serum or serve as a component of multibiosensors for determination of important blood substances. Determination of activity of other kinases by the developed biosensor is also possible for research purposes. PMID:26452867

    Zebrafish are an important laboratory animal model for biomedical research and are increasingly being used for behavioral neuroscience. Tricaine methanesulfonate (MS222) is the standard agent used for euthanasia of zebrafish. However, recent studies of zebrafish behavior suggest that MS222 may be aversive, and clove oil might be a possible alternative. In this study, we compared the effects of MS222 or clove oil as a euthanasia agent in zebrafish on the volume of blood collected and on serum levels of cortisol. Greater amounts of serum could be collected and lower serum levels of cortisol were present in fish euthanized with clove oil compared with equipotent dose of MS222. Euthanasia with clove oil did not blunt the expected elevation of serum cortisol levels elicited by an acute premortem stress. According to our findings, clove oil is a fast-acting agent that minimizes the cortisol response to euthanasia in zebrafish and allows the collection of large volumes of blood postmortem. These results represent a significant refinement in euthanasia methods for zebrafish. PMID:26424256

    The continuous use of synthetic hormones as contraceptive pill or hormonal replacement therapy among women is increasing day by day. The widespread use of different formulations as oral contraceptives by women throughout their reproductive cycle has given rise to a serious concern for studying the effects of oral contraceptives on enzymatic profile and DNA damage in peripheral blood lymphocytes among users. The present study was carried out on women taking oral contraceptives. The study was based on the questionnaire having the information of reproductive history, fasting, age, health, nature of menstrual cycle, bleeding and other disease. The profile of the blood serum enzymes i.e. alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH), aminotransferases (SGOT and SGPT), serum proteins (albumin and globulin) and DNA damage in lymphocytes was studied among users and non-users. The results of the present study suggest that OCs not only effects enzymatic activity but also results in DNA damage that may vary with the duration of using oral contraceptives. A significant increase in LDH, GGT, SGPT, SGOT, globulin and decrease in ALP as well as albumin was found among users as compared to non-users. The observed DNA damage was more in users as compared to non-users. Hormonal contraceptives seem to exert DNA damage and also have significant effects on blood serum enzymes. PMID:27382200

    The sampling of 100 patients with chronic autoimmune nettle rash and control group of 30 healthy donors was analyzed for identification of level of interleukin (IL)-4, IL-10, IL-17, IL-18 and γ-interferon (IFN) in serum of patients. The same sampling was examined using method ex vivo for spontaneous and induced production by cells of immune system. In patients with chronic autoimmune nettle rash increasing of spontaneous production of IL-4 and spontaneous and induced production of IL-17 and IFN was identified. The decreasing of spontaneous and induced production of IL-18 was detected too. These occurrences indicate to simultaneous activation of Th1, Th2 and Th17-population of T-lymphocytes. The analysis of level of cytokines in blood serum established only decreasing of level of IL-4 in patients with chronic autoimmune nettle rash as compared with healthy individuals. The level of other analyzed cytokines had no reliable differences that demonstrate both low informativeness of detection ofcontent of cytokines in blood serum and advantage of application of method ex vivo with detection of level of cytokines in whole blood.

    The comparative analysis of the rat liver and blood serum creatine kinase, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and purine nucleoside phosphorylase post-radiation activity levels after a total two-hour long single and fractional exposure of the animals to low-intensity 900 MHz frequency electromagnetic field showed that the most sensitive enzymes to the both schedules of radiation are the liver creatine kinase, as well as the blood serum creatine kinase and alkaline phosphatase. According to the comparative analysis of the dynamics of changes in the activity level of the liver and blood serum creatine kinase, alanine aminotransferase, aspartate aminotransferase and purine nucleoside phosphorylase, both single and fractional radiation schedules do not affect the permeability of a hepatocyte cell membrane, but rather cause changes in their energetic metabolism. The correlation analysis of the post-radiation activity level changes of the investigated enzymes did not reveal a clear relationship between them. The dynamics of post-radiation changes in the activity of investigated enzyme levels following a single and short-term fractional schedules of radiation did not differ essentially.

    Objective To examine the change of body weight (BW) and blood pressure (BP) in obese rats, clarify relationships between BP and BW and other factors. Methods Male Spraque-Dawley rats were fed either with normal diet (ND) or high calorie diet (HC) for 20 weeks. BW and BP of tail artery were observed biweekly and tetraweekly respectively; serum leptin and fasting insulin (FINS) were detected by enzyme-linked immunoadsordent assay (ELISA) and radioimmunoassay (RIA) respectively. Fasting plasma glucose (FPG) and free fatty acid(FFA) were measured by conventional means. Results BW, abdominal fat weight (AFW), ratio of abdominal fat weight to body weight (RF/W), systolic blood pressure (SBP), diastolic blood pressure (DBP), serum levels of leptin and FINS, FPG, FFA increased in the HD group after 20 weeks diet intervention (P<0.05 or P<0.01). SBP was strongly correlated with BW, leptin, FINS and FFA (P<0.05), DBP was correlated with FFA (r=0.47, P<0.05). In addition, leptin was positively correlated with BW, AFW, RF/W, FINS and FFA (P<0.05 or P<0.01). Conclusion In this study of high calorie-diet induced rats, the gain of BW is accompanied by increased BP. The obese rats have hyperleptinemia, hyperinsulinemia, hyperglycemia and dyslipidemia which may have important effects on the development of obesity-related hypertension. RF/W is the key factor in which affect serum leptin level.

    Full Text Available Introduction & Objective: One of the important functions of the cornea is to maintain normal vision by refracting light onto the lens and retina. This property is dependent in part on the ability of the corneal epithelium to undergo continuous renewal. Ocular surface failure which follows a variety of endogenous and exogenous precipitating factors, the most common being: chemical trauma, infection, alkaline burn, inflammation and hereditary conditions, lid or lash abnormalities, tear deficiency or reduced sensation. The core principal underpinning management strategy for ocular surface failure is establishing or promoting new growth of healthy conjunctiva and corneal epithelium. This process is mediated by many proteins that are inducers of corneal cell migration, proliferation, and differentiation. The current study was performed to investigate the efficacy of umbilical cord serum on alkaline corneal epithelial wound healing in the rabbit model. Materials & Methods: In this study conducted at Yasuj University of Medical Sciences in 2010, thirty two rabbits were randomly assigned into two equal groups. Central corneal alkali wound was formed in one eye of the rabbits by applying a 6-mm round filter paper, soaked in 1 N NaOH, for 60 seconds. Group one of animals received umbilical cord blood serum and group two received Sno*Tear in the eyes. The treatment was dosed 4 times a day with the eye drops, and epithelial wound closure was recorded using slit lamp. The data were analyzed to determine the rate of wound closure. Results: The mean wound radius closure rate was 0.77 mm/day (SD=0.013 for umbilical cord blood serum-treated eyes, 0.73 mm/day (SD=0.018 for artificial tear-treated eyes. Conclusion: This study shows that alkali-injured corneal epithelial wound heal faster when treated with umbilical cord blood serum than with artificial tear in rabbit model.

    We evaluated a plastic evacuated blood-drawing tube containing an integral serum-separating barrier gel, by direct comparison with a glass counterpart. The plastic tube demonstrated no differences when compared for common clinical chemistry analytes with multiple types of instruments and systems. A total of 260 such different combinations were studied with emphasis on tests sensitive to drawing and handling indexes such as lactate dehydrogenase and potassium. A total of six separate blood drawings were tested with no significant differences noted in these tests. The total study included subjective evaluations of the plastic tube's use as a blood-drawing device and objective studies based on quantitative test results from normal and hospitalized patients and use of the primary sampling tubes (both plastic and glass) for 48-h storage.

    The plasma and serum of Crocodylus siamensis have previously been reported to exhibit potent antimicrobial, antioxidant, and anti-inflammatory activities. During wound healing, these biological properties play a crucial role for supporting the formation of new tissue around the injured skin in the recovery process. Thus, this study aimed to evaluate the wound healing properties of C. siamensis plasma and serum. The collected data demonstrate that crocodile plasma and serum were able to activate in vitro proliferation and migration of HaCaT, a human keratinocyte cell line, which represents an essential phase in the wound healing process. With respect to investigating cell migration, a scratch wound experiment was performed which revealed the ability of plasma and serum to decrease the gap of wounds in a dose-dependent manner. Consistent with the in vitro results, remarkably enhanced wound repair was also observed in a mouse excisional skin wound model after treatment with plasma or serum. The effects of C. siamensis plasma and serum on wound healing were further elucidated by treating wound infections by Staphylococcus aureus ATCC 25923 on mice skin coupled with a histological method. The results indicate that crocodile plasma and serum promote the prevention of wound infection and boost the re-epithelialization necessary for the formation of new skin. Therefore, this work represents the first study to demonstrate the efficiency of C. siamensis plasma and serum with respect to their wound healing properties and strongly supports the utilization of C. siamensis plasma and serum as therapeutic products for injured skin treatment.

    Hemodialysis remains the standard therapy to treat patients affected with end-stage renal disease by removing metabolites accumulated in blood plasma. The efficiency of hemodialysis is mainly monitored by urea clearance, which is routinely checked in clinical laboratory practice. However, there is mounting evidence that the clearance behavior of selected single metabolites is not sufficient to predict long-term outcome of treatment. To address this problem, we evaluated the potential of nuclear magnetic resonance spectroscopy for monitoring hemodialysis efficiency by comprehensive profiling of blood serum metabolites. We carried out a pilot study with a cohort of end-stage chronic kidney disease patients (n = 29), analyzing their serum prior and immediately after hemodialysis. To account for supposed variability in the accumulation of metabolites and efficiency of hemodialysis, patients' blood sera were repeatedly collected over a period of several months. Our results revealed that the metabolic profile in terms of concentrations varied considerably between patients but was comparably constant on the patient's level over the period of 4 months. Interestingly, also the individual clearance of the metabolites was characteristic for each patient. Thus, it is conceivable that the observed patient-dependent clearance patterns reflect to some extent the patients' long-term perspectives. We conclude that nuclear magnetic resonance spectroscopy is an optimal tool to complement traditional clinical methods based on a single variable, providing comprehensive and much more global information, which is crucial for patient evaluation and the development of improved treatments of kidney failure.

    Full Text Available Training-induced muscle, skeletal and joint trauma may result in acute phase response reflected by the changes in the blood concentration of serum amyloid A (SAA in racehorses. It remains yet unclear if such systemic reaction could be triggered by sport injuries and what is the impact of different types of musculoskeletal trauma on SAA concentrations in racehorses. This study aimed to determine changes in the SAA blood concentration in racehorses with different types of injuries of musculoskeletal system.The study involved 28 racehorses diagnosed after the race with bone fractures (n = 7, dorsal metacarpal disease (n = 11, joint trauma (n = 4 or tendon and muscle trauma (n = 6 and 28 healthy control racehorses. Serum samples were collected twice, between 1 and 4 days of the injury or succesful completion of the race. SAA concentration was measured using the commercial ELISA kit. Differences between mean SAA concentration in respective groups were analyzed using ANOVA and Tukey post-hoc test.Mean SAA concentration within the first 4 days of the injury of muscle and tendon was significantly higher than in bone fractures, dorsal metacarpal disease, joint trauma or in the healthy horses (p<0,001. There were no significant differences between the other groups.Strain injuries of muscle and tendons can cause a moderate increase in SAA blood concentration in racehorses, reflecting the occurrence of the acute phase response. Similar reaction is not observed in the stress-related bone injuries.

    Full Text Available The aim of present study was to test hypothesis, that the leptin gene single nucleotide polymorphism (C/T giving missense mutation (Arg25Cys has an effect on concentration of blood serum total cholesterol, beta-hydroxybutyrate and urea in cattle. The experiment were performed in 58 Czech Pied bulls at 240 ± 9 days of age, which were divided in three experimental groups depending on different leptin genotypes (CC, n=28; CT, n=21; TT, n=9. Resulting genotypes in the exon 2 were CC (48.3%, CT (36.2%, and TT (15.5%. There were no differences in serum total cholesterol, urea, beta-hydroxybutyrate concentrations among the genotypes. Based on our results we may assume that analysed SNP of leptin gene have no effect on nutritional status and energy balance in fattened cattle.

    As a specific item mentioned in traditional Chinese medicine theory, processing can fulfill different requirements of therapies. Crude and wine-processed rhubarbs are used as drastic and mild laxatives, respectively. In this study, a practical method based on ultra-fast liquid chromatography coupled with diode-array detection and ion trap time-of-flight mass spectrometry was developed to screen and analyze multiple absorbed bioactive components and metabolites in the serum of both normal and acute blood stasis rats after oral administration of crude or wine-processed rhubarbs. A total of 16 compounds, mainly including phase II metabolites, were tentatively identified. Possible explanations for the processing-induced changes in pharmacological effects of traditional Chinese medicines were first explored at serum pharmacochemistry level.

    Left ventricular hypertrophy (LVH) is considered an independent risk factor even in the absence of systemic hypertension. Electrocardiographic (ECG) LVH with repolarisation changes has been found in some countries to carry more coronary risk than LVH alone. How far this observation is true among adult Nigerians is not known. We therefore decided to study adult Nigerians with ECG-LVH with or without ST-T waves changes and compare them with normal age matched controls (without ECG-LVH) in relation with established modifiable risk factors such as systemic hypertension (BP), body mass index (BMI), fasting blood sugar (FBS) and serum lipids such as total cholesterol (Tc), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglyceride (TG). Adult Nigerians who were consecutively referred to the ECG laboratory were randomly recruited. Three hundred patients were studied. Their blood pressures (BP) as well as body mass indices were recorded after recording their resting 12 read ECG using portable Seward 9953 ECG machine. Their waist-hip ratio (WHR) was also recorded. Blood samples were taken to determine their fasting blood sugar and serum lipids. Their ECG tracings were read by the cardiologists involved in the study while the blood samples were analysed by the chemical pathologist also involved in the study. At the end of the ECG reading, the patients were divided into 3 groups according to whether there was no ECG-LVH (control group A), ECG-LVH alone (group B), and ECG-LVH with ST-T waves changes (group C). One hundred and fifty (50%) patients belonged to group A, 100 (33.3%) patients to group B and 50 (16.7%) group C. Group B patients were found to have higher modifiable risk factors in form of systemic BP. Tc, LDL-C, and WHR compared to group A. However, the group C patients had increased load of these coronary risk factors in terms of BP elevation, higher BMI, FBS, and scrum cholesterol compared to group B. In addition

    The role of vasopressin (AVP) in the pathophysiology of cardiovascular disease is controversial, but this peptide hormone is elevated in heart failure and some forms of hypertension. Also, AVP has vasoconstrictor, mitogenic, hyperplasic and renal fluid retaining properties which, by analogy with angiotensin II, may have deleterious effects when present in chronic excess. Furthermore, cholesterol blood levels are also associated with hypertension, although the underlying mechanism is not known. Here we analyze the relationship between blood total cholesterol levels and serum vasopressin- degrading cystyl-aminopeptidase activity (AVP-DA) in healthy humans, and the differences between men and women. Linear correlation coefficients were calculated to test relationships between AVP-DA and blood total cholesterol levels. Sex differences were observed for AVP-DA, being this activity higher in men than in women. According to the linear model of the regression analysis, AVP-DA showed a significant negative correlation with blood total cholesterol levels in men, whereas no correlation was observed in women. Several studies in humans demonstrate the existence of greater plasma AVP concentrations in normal men compared to normal women, which could explain the gender-differences observed in the present work in relation with AVP-DA. However, AVP-DA is related to blood cholesterol levels only in men, although in our hands, women showed higher blood cholesterol levels than men. This could indicate that the risk of high cholesterol-related hypertension is more probable in men than in women. Although AVP-DA misregulation could be involved in the pathogenesis of hypertension, its relation with cholesterol levels appears only in men, but not in women.

    2005-01-01

    The effects of oligosaccharide and creatine (Cr) supplementation on glucose, lactic acid and urea nitrogen levels in blood and activity of serum creatine kinase (CK) were explored. Twenty CUBA male athletes were divided into 4 groups: group A (supplementation of Cr alone), group B (supplementation of oligosaccharide), group C (supplementation of oligosaccharide and Cr) and group D (placebo control group). By using orthogonal L4 table (23), the experiment was performed. There were factors including oligosaccharide (carbohydrate, CHO), Cr and their correlation. Each factor had two levels: supplementation and no-supplementation. The results showed that the supplementation of CHO or Cr alone, combined supplementation of CHO and Cr could significantly reduce the glucose, urea nitrogen levels in blood and serum CK activity after competition in the athletes. Moreover, the effects of combined supplementation of CHO and Cr were more satisfactory. It was concluded that supplementation of CHO and Cr could promote the recovery of physical performance and athletic abilities after athletics in basketball athletes.

    Full Text Available The influence of zearalenone on blood serum protein status and the feasibility of utilizing a modified clinoptilolite and esterified glucomannan to alleviate its harmful effects was examined in two trials, 31 and 29 days long, conducted on a total of 64 pigs (32 each 60 days old, divided into four groups, each containing 8 pigs. Control groups (K received noncontaminated feed, while experimental groups received feed supplemented with 3.84 mg/kg in the first trial and 5.12 mg/kg of zearalenone in the second trial. Pigs in the first experimental groups (O-I were given feed with toxin only. Modified clinoptilolite in the amount of 0.2% and esterified glucomannan in the amount of 0.1% were introduced in contaminated feed of the second (O-II and the third experimental groups (O-III of both trials. With the use of contaminated feed, a declining trend of the A/G ratio was observed: decrease of albumin content and increase of globulin content on account of the _ globulin fraction. A decrease of the _ globulin fraction was detected at the same time. Total protein concentration was also lower. The application of adsorbents successfully alleviated harmful effects of the F-2 toxin on the affected biochemical parameters in blood serum.

  6. Biological indicators of radiation exposure - increase of blood serum amylase following irradiation of salivary glands

    International Nuclear Information System (INIS)

    In this paper, an isoenzyme test is described which enables the proteins of pancreas to be differentiated from those of the salivary glands. This isoenzyme test, in combination with an antibody lipase test which in turn is sensitive to the pancreatic enzyme triacylglycerinlipase, has been used to examine a total of the 42 patients under radiation therapy. 25 of these patients had been subjected to partial body exposure of the head region and 17 to whole body exposure. The results show that the amount of activity increase depends upon the dose to the salivary glands and that almost exclusively the isoenzymes of these organs are responsible for the radiation-induced activity increase in the serum. The isoenzyme test proved to be a good approach in cases where pathogenic variations in the serum α-amylase activity concerning primarily the pancreatic glands had to be differentiated from radiation-induced variations.

    Full Text Available Abstract. Progressive obstruction and lung tissue remodeling comprise an important feature of the airways in COPD patients. The main processes involved in tissue remodeling in COPD are protease/antiprotease, oxidant/antioxidant imbalances, like as inflammatory and fibrotic events that contribute to development or progression of disease. TGFβ is a multifunctional growth factor that regulates synthesis of extracellular matrix proteins, primarily collagen and fibronectin, thus inducing fibrosis of respiratory ways. The aim of our study was to determine levels of TGFβ in serum and bronchoalveolar lavage fluid (BALF of COPD patients. All the patients with COPD had increased levels of TGFβ in serum, as compared with subjects without COPD (p < 0.01, but there was no difference in TGFβ concentration between patients at different stages of disease. Increased phagocytic activity of blood monocytes was found in 81% of COPD patients, as compared to controls. Phagocytosis of apoptotic T­cells and bacterial infection of monocytes leads to increased secretion of TGFβ and it may cause higher levels of TGF β in peripheral blood. TGFβ concentration in BALF of patients at stage III of disease was higher than in the patients at stage II (p < 0.05. The level of TGFβ in BALF directly correlates with number of alveolar macrophages (r = 0.39; р = 0.03. These data indicate that TGFβ is involved in chemotaxis of macrophages in COPD patients’ airways. We conclude that increased secretion of TGFβ by peripheral blood monocytes may be a result of their high phagocytic activity. Hence, TGFβ mediates interactions between the two main components underlying lung tissue remodeling, i.e. fibrosis of respiratory airways, and development of emphysema in COPD.

    Full Text Available CONTEXT: There is no rapid and cost effective tool that can be implemented as a front-line screening tool for Alzheimer's disease (AD at the population level. OBJECTIVE: To generate and cross-validate a blood-based screener for AD that yields acceptable accuracy across both serum and plasma. DESIGN, SETTING, PARTICIPANTS: Analysis of serum biomarker proteins were conducted on 197 Alzheimer's disease (AD participants and 199 control participants from the Texas Alzheimer's Research Consortium (TARC with further analysis conducted on plasma proteins from 112 AD and 52 control participants from the Alzheimer's Disease Neuroimaging Initiative (ADNI. The full algorithm was derived from a biomarker risk score, clinical lab (glucose, triglycerides, total cholesterol, homocysteine, and demographic (age, gender, education, APOE*E4 status data. MAJOR OUTCOME MEASURES: Alzheimer's disease. RESULTS: 11 proteins met our criteria and were utilized for the biomarker risk score. The random forest (RF biomarker risk score from the TARC serum samples (training set yielded adequate accuracy in the ADNI plasma sample (training set (AUC = 0.70, sensitivity (SN = 0.54 and specificity (SP = 0.78, which was below that obtained from ADNI cerebral spinal fluid (CSF analyses (t-tau/Aβ ratio AUC = 0.92. However, the full algorithm yielded excellent accuracy (AUC = 0.88, SN = 0.75, and SP = 0.91. The likelihood ratio of having AD based on a positive test finding (LR+ = 7.03 (SE = 1.17; 95% CI = 4.49-14.47, the likelihood ratio of not having AD based on the algorithm (LR- = 3.55 (SE = 1.15; 2.22-5.71, and the odds ratio of AD were calculated in the ADNI cohort (OR = 28.70 (1.55; 95% CI = 11.86-69.47. CONCLUSIONS: It is possible to create a blood-based screening algorithm that works across both serum and plasma that provides a comparable screening accuracy to that obtained from CSF analyses.

    Full Text Available Introduction: Historically, serum alanine transaminase (ALT has been used as a surrogate marker in the detection of hepatitis viruses in blood donors. With the availability of newer sensitive technologies for the detection of seroconversion, the value of ALT becomes questionable but continues to be used for this purpose with subsequent discarding of ALT elevated blood units. Objective: The present study aims to evaluate the significance and cost effectiveness of ALT as a surrogate marker for hepatitis C virus infection in healthy asymptomatic blood donors who were serologically negative. Materials and Methods: The study was conducted at clinical laboratory of a tertiary care hospital for a period of one year from November 2006 to October 2007. All donors were screened serologically for hepatitis B, C and HIV I and II, syphilis and malaria and those tested positive were excluded from further evaluation. Gender-wise reference ranges and minimal and markedly raised results for ALT (described respectively as one and two folds increase above reference range were defined and, accordingly, donors were grouped into three. Two hundred seronegative blood donors were randomly selected from all three groups of ALT results and tested for hepatitis C nucleic acid through Amplicor; HCV RNA test. The cost of discarding an ALT -only elevated blood unit was also assessed. During the study period, 25117 subjects donated blood. Eight hundred and Results: seventy two donors (3.4% were positive for one or more serological tests. ALT of all donors ranged from 0-1501 U/L (Mean ± SD; 33.4 ± 25.45U/L. The donors seronegative for all disease markers were 24245 (96.6%. Of these, 21164 (87.2% donors had their ALT within reference range while 2874 (11.8% and 207 (0.8% of donors had minimal and markedly elevated results. Thus, 621 blood bags (red cells, platelets and plasma costing $ 39200.0 were discarded based on ALT results alone. Of 200 seronegative donors evaluated

    Phytohemagglutinin (PHA) and concanavalin A (Con A)-induced blastogenesis of peripheral blood lymphocytes was examined in heat-stressed pre- and postpartal sheep. The peak responses of lymphocytes to PHA and Con A in heat-stressed sheep revealed significant reduction before and after parturition compared with those in the corresponding control animals kept under thermoneutral conditions. Furthermore, the effect of serum from control or heat-stressed sheep on PHA-induced lymphocyte blastogenesis was examined. Supplementation of serum from heat-stressed sheep significantly suppressed the blastogenesis of lymphocytes obtained from healthy sheep, bovine, and human donors. Unlike dexamethasone, heat-stressed sheep serum did not inhibit IL-2 production by PHA-stimulated human peripheral blood lymphocytes. These results indicate that the immunosuppression of heat-stressed sheep is in part mediated by serum factor(s) that can modulate T-cell function in a species nonspecific manner.

    Full Text Available The comparison of some serum protein concentrations was performed on 12 Yugoslav Trotter mares and their newborn foals. The mares included in the evaluation were divided into two groups of 6 each. The mares in the first group were vaccinated against equine herpes virus 1 and 4, in the 5th, 7th and 9th month of pregnancy, while mares in the second group were not vaccinated at all. Pregnant mares were clinically observed during the last stage of pregnancy and blood for biochemical evaluations was sampled immediately after foaling. Foals were clinically observed for seven days after birth and blood samples were collected immediately after foaling (before nursing, and 24, 48, 72 and 168 hours after birth. Foals included in the evaluation were divided into two groups according to the group allocation of the respective mares. All mares gave birth to normal foals in expected terms. Biochemical examination revealed slightly lower total gammaglobulin and IgG values in tested mares compared to the values obtained in other horse breeds. The antibody titres against equine herpes virus-1 reached the level that provides sufficient protection in vaccinated mares. Gammaglobulin and traces of IgG were present in the blood serum of foals tested immediately after birth and before nursing. A significant increase of IgG and gammaglobulin concentration was revealed in all foals after the first 24 hours of life. The observed first day increase of concentration was followed by stagnation of gammaglobulin and IgG levels in all foals. Total protein values showed a significant increase 24 hours after the first intake of colostrum in all foals. Immunoglobulin G concentration established by semiquantitative test was considered low positive in 16.67% and in 33.34% of foals from vaccinated and unvaccinated mares, respectively. Turbidimetric analyses of the same samples revealed sufficient Ig transfer, i.e. Ig concentration over 8 g/L. Comparison of the results obtained by the

  15. Dramatic effect on Selenium concentration in blood serum due to the difference between the Hungarian and Indian dietary habits

    International Nuclear Information System (INIS)

    Complete text of publication follows. The importance of Selenium as trace element in animals, as well as in humans is well known. The deficiency of Selenium was observed in case of several heavy or fatal clinical events such as high infant mortality, premature, malformations and even prostate cancer. Hungary is in the top of their worldwide statistic with parallel of the low concentration of Selenium in soil as well as in food. The direct correlation can explain in Venezuela, where the prostate cancer is 'unknown disease'. The concentration of Selenium in India is higher than the worldwide level. Under the scientific bilateral cooperation 'Speciation dependent studies on physicochemical behavior of some elements in trace scale in natural and synthetic system' the Selenium was determined in human blood serum from the group of Hungarian and group of Indian patients. The samples were given in same time from each group. The main goal of the study was explain the effect of the traditional dietary habit for the level of Selenium. Therefore the samples were taken from the visiting scientist just arrived to the host institute as well as from the host scientists too. After 2 weeks stay the sampling was repeated, when the guest scientists eat the same food as the host scientists. The measurements were done in Thermo-2 ICP-MS from blood-serum separated by centrifuge. The results are summarized in Table 1. Dramatic effect was found for the level of Selenium in blood serum. As it was expected the Hungarian samples showed low concentration of Selenium in starting of the visit, as well as the high concentration was found in Indian sample, comparing to the Hungarian sample. After two weeks the Hungarian sample showed much higher concentration, however it was still less, than in Indian sample. Similar effect was found during the visit the Indian scientists in Hungary, however their Selenium concentration decreased not so spectacular due to the Selenium 'store' in body. The general

    Full Text Available Abstract Background This research was conducted to explore the relationships between the levels of omega-3 fatty acids in serum phospholipid and key fatty acid ratios including potential cut-offs for risk factor assessment with respect to coronary heart disease and fatal ischemic heart disease. Methods Blood samples (n = 2053 were obtained from free-living subjects in North America and processed for determining the levels of total fatty acids in serum phospholipid as omega-3 fatty acids including EPA (eicosapentaenoic acid, 20:5 n-3 and DHA (docosahexaenoic acid, 22:6 n-3 by combined thin-layer and gas-liquid chromatographic analyses. The omega-3 levels were correlated with selected omega-6: omega-3 ratios including AA (arachidonic acid, 20:4n-6: EPA and AA:(EPA+DHA. Based on previously-published levels of omega-3 fatty acids considered to be in a 'lower risk' category for heart disease and related fatality, 'lower risk' categories for selected fatty acid ratios were estimated. Results Strong inverse correlations between the summed total of omega-3 fatty acids in serum phospholipid and all four ratios (omega-6:omega-3 (n-6:n-3, AA:EPA, AA:DHA, and AA:(EPA+DHA were found with the most potent correlation being with the omega-6:omega-3 ratio (R2 = 0.96. The strongest inverse relation for the EPA+DHA levels in serum phospholipid was found with the omega-6: omega-3 ratio (R2 = 0.94 followed closely by the AA:(EPA+DHA ratio at R2 = 0.88. It was estimated that 95% of the subjects would be in the 'lower risk' category for coronary heart disease (based on total omega-3 ≥ 7.2% with omega-6:omega-3 ratios Conclusions Strong inverse correlations between the levels of omega-3 fatty acids in serum (or plasma phospholipid and omega-6: omega-3 ratios are apparent based on this large database of 2053 samples. Certain fatty acid ratios may aid in cardiovascular disease-related risk assessment if/when complete profiles are not available.

    Training nonhuman animals in captivity for participation in routine husbandry procedures is believed to produce a lower stress environment compared with undergoing a general anesthetic event for the same procedure. This hypothesis rests largely on anecdotal evidence that the captive subjects appear more relaxed with the trained event. Blood markers of physiological stress responses were evaluated in 4 captive grizzly bears (Ursus arctos horribilis) who were clicker-trained for blood collection versus 4 bears who were chemically immobilized for blood collection. Serum cortisol and immunoglobulin A (IgA) and plasma β-endorphin were measured as indicators of responses to stress. Plasma β-endorphin was not different between the groups. Serum IgA was undetectable in all bears. Serum cortisol was undetectable in all trained bears, whereas chemically immobilized bears had marked cortisol elevations (p bears with extensive recent immobilization experience. These findings support the use of positive reinforcement training for routine health procedures to minimize anxiety.

    Full Text Available Forty-five crossbred rabbits (Dutch × New Zealand White of mixed sexes with age between 5 and 7 weeks were divided into 5 groups of 9 rabbits and fed camel blood–rumen content mixture (CBRCM for 10 weeks. The CBRCM which contained 36.40% crude protein and 22.36% crude fibre was included at 0, 10, 20, 30 and 40% levels in diets of group 1, 2, 3, 4 and 5 respectively. The packed cell volume (PCV, red blood cells (RBC, mean corpuscular volume (MCV, mean corpuscular haemoglobin (MCH and mean corpuscular haemoglobin concentration (MCHC were not significantly different (P>0.05 among the treatments groups, although the haemoglobin (Hb and white blood cells (WBC were significantly (P<0.05 influenced by the treatments. The number of basophils, neutrophils, eosinophils and lymphocytes were not affected by the levels of inclusion, however, only the monocytes differed significantly (P<0.05 among the treatments. All values for blood parameters were within the normal range for growing rabbit. Thus, the study indicated that up to 40% CBRCM could be incorporated into the diets of growing rabbits without compromising the health status of the rabbits.

    Proton nuclear magnetic resonance ((1)H-NMR)-based metabolomics enables the high-resolution and high-throughput assessment of a broad spectrum of metabolites in biofluids. Despite the straightforward character of the experimental methodology, the analysis of spectral profiles is rather complex, particularly due to the requirement of numerous data preprocessing steps. Here, we evaluate how several of the most common preprocessing procedures affect the subsequent univariate analyses of blood serum spectra, with a particular focus on how the standard methods perform compared to more advanced examples. Carr-Purcell-Meiboom-Gill 1D (1)H spectra were obtained for 240 serum samples from healthy subjects of the Asklepios study. We studied the impact of different preprocessing steps--integral (standard method) and probabilistic quotient normalization; no, equidistant (standard), and adaptive-intelligent binning; mean (standard) and maximum bin intensity data summation--on the resonance intensities of three different types of metabolites: triglycerides, glucose, and creatinine. The effects were evaluated by correlating the differently preprocessed NMR data with the independently measured metabolite concentrations. The analyses revealed that the standard methods performed inferiorly and that a combination of probabilistic quotient normalization after adaptive-intelligent binning and maximum intensity variable definition yielded the best overall results (triglycerides, R = 0.98; glucose, R = 0.76; creatinine, R = 0.70). Therefore, at least in the case of serum metabolomics, these or equivalent methods should be preferred above the standard preprocessing methods, particularly for univariate analyses. Additional optimization of the normalization procedure might further improve the analyses.

    Full Text Available Pneumonia in preruminant calves is a multifactorial disease. Infectious agents, the environment, management and the immune status of the calves are all important factors in determining the outcome of an infection. Until today, the level and composition of circulating immune complexes in preruminant calves with pneumonia have not been studied in detail. We performed this work with the aim to determine whether pneumonia in three-month-old calves is followed by changes in the immune complex level and changes in the γ-globulin level as their possible constituents. Immune complexes from the calves’ sera were isolated by polyethylene glycol (PEG precipitation methods. Optical density at 350 nm (OD350 of redissolved precipitates was measured to determine the circulating immune complexes level. The OD350 level of PEG precipitates of calves with pneumonia at the time of diagnosis was 0.577±0.206 and it was statistically significantly higher (p<0.001 than OD350 the level of PEG precipitates of healthy calves (0.286±0.080. Electrophoretic analysis of sera and PEG precipitates showed that both slow and fast γ-globulins are found among serum and immune-complexes' γ-globulins, but the concentration of fast γ-globulins was significantly lower in sera of diseased calves. The level of PEG precipitable immune complexes was not correlated with the concentration of serum and PEG precipitable g-globulins. The results of this study have shown that by relatively simple PEG precipitation assay it is possible to detect an increased level of circulating immune complexes in calves with pneumonia. This can be used as an additional diagnostic parameter for the detection and follow up of the disease.

    Full Text Available Although human pluripotent stem cells (hPSCs can proliferate robustly on the feeder-free culture system, genetic instability of hPSCs has been reported in such environment. Alternatively, feeder cells enable hPSCs to maintain their pluripotency. The feeder cells are usually grown in a culture medium containing fetal bovine serum (FBS prior to coculture with hPSCs. The use of FBS might limit the clinical application of hPSCs. Recently, human cord blood-derived serum (hUCS showed a positive effect on culture of mesenchymal stem cells. It is interesting to test whether hUCS can be used for culture of feeder cells of hPSCs. This study was aimed to replace FBS with hUCS for culturing the human foreskin fibroblasts (HFFs prior to feeder cell preparation. The results showed that HFFs cultured in hUCS-containing medium (HFF-hUCS displayed fibroblastic features, high proliferation rates, short population doubling times, and normal karyotypes after prolonged culture. Inactivated HFF-hUCS expressed important genes, including Activin A, FGF2, and TGFβ1, which have been implicated in the maintenance of hPSC pluripotency. Moreover, hPSC lines maintained pluripotency, differentiation capacities, and karyotypic stability after being cocultured for extended period with inactivated HFF-hUCS. Therefore, the results demonstrated the benefit of hUCS for hPSCs culture system.

Blood samples from both the treatment group (N=33) and control group (N=30) were taken before and after treatment, and the serum levels of TNF-α, IFN-γ and IL-6 were determined by radio-immunoassay and ELISA. The total effective rate achieved in the treatment group was 90.91%. The remarkably high serum levels of TNF-α, IFN-γ and IL-6 in patients before treatment (P<0.01) were obviously decreased after one course of treatment (P<0.05) and were close to those of healthy subjects after two course of treatment (P>0.05). The data demonstrate that LHXT has the actions of reducing serum levels of TNF-α, IFN-γ and IL-6 in psoriasis of blood-heat type, and may exert a pharmacological effect targeting at the cytokines.

    The ergoline alkaloid fumigaclavine A (FuA) is one of the major mycotoxins produced by Aspergillus fumigatus, the main causative fungal agent of avian aspergillosis. To study in situ production of FuA, post-mortem respiratory tissues of various avian species, as well as blood samples of falcons (Falco sp.), were analysed by enzyme immunoassay (EIA). At a detection limit of 1.5 ng/ml, FuA EIA positive results were obtained for tissue samples from seven (64%) out of 11 birds with confirmed aspergillosis, with a maximum concentration of 38 ng/g, while all controls (n = 7) were negative. No FuA could be detected in blood serum (detection limit 0.7 ng/ml) of 15 falcons, experimentally inoculated with A. fumigatus conidia. Fungal mycelium material from tissue of clinical aspergillosis cases, cultured on malt extract agar, was highly positive in the FuA EIA in milligrams per gram range. Chromatographic analysis of mycelium extracts revealed the co-presence of FuA and the structurally related fumigaclavine C (FuC). Alkaline hydrolysis of FuA and FuC yielded the corresponding deacetylation products, FuB and FuE. This is the first report showing that fumigaclavine alkaloids are produced by A. fumigatus in situ during the course of clinical aspergillosis in birds; however, the role of these compounds in the pathogenesis of this disease is still unknown.

    The protein fraction isolated from blood of seal, Phoca groenlandica, has been found to produce hyperalgesic effect on rats exposed to thermic or electrocutaneous nociceptive stimulation, but fail to affect writhes provoked by intraperitoneal injection of acetic acid solution on mice. When combined with morphine, the fraction lowered completely its narcotic analgetic action in the above mentioned tests. On the contrary, these same proteins combined with promedol or fentanil enhanced and prolonged analgetic effect of the latter. Tested in vitro the protein showed neither opioid nor anti-opioid activity. Therefore it is reasonable to suppose that neurophysiological activity of the isolated fraction is due to the peptides formed on enzymatic hydrolysis of proteins in vivo rather than these proteins as such.

    Objective: To analyze effect of Naloxone combined with noninvasive positive pressure ventilation therapy on blood gas indexes and serum indexes of COPD complicated with respiratory failure patients. Methods: 116 cases of COPD complicated with respiratory failure patients treated in our hospital from June 2012 to June 2014 were enrolled and randomly divided into observation group (58 cases) who received Naloxone combined with noninvasive positive pressure ventilation therapy, and control group (58 cases) who received plain noninvasive positive pressure ventilation therapy. Then differences of blood gas indexes, serum inflammatory factor levels and serum prognosis-related factor levels of both groups were compared. Results: 1) after treatment, artery blood PaO2 and PH level of observation group were higher than those of control group; PaCO2 level was lower than that of control group (P<0.05); 2) after treatment, serum factor levels of IL-13, IL-18, sICAM-1, PGE2 and hs-CRP, etc of observation group were all significantly lower than those of control group (P<0.05); 3) after treatment, serum α1-AT, D-Dimer and BNP levels of observation group were lower than those of control group; FT3 level was higher than that of control group (P<0.05). Conclusion:Naloxone combined with noninvasive positive pressure ventilation therapy helps to improve ventilation and oxygenation levels of COPD complicated with respiratory failure patients, reduce systemic inflammatory response and optimize prognosis-related indexes.

    Minerals are inorganic compounds that are essential to the support of a variety of biological functions. Understanding the range and variability of the content of these minerals in biological samples can provide insight into the relationships between mineral content and the health of individuals. In particular, abnormal mineral content may serve as an indicator of illness. The development of robust, reliable analytical methods for the determination of the mineral content of biological samples is essential to developing biological models for understanding the relationship between minerals and illnesses. This manuscript describes a method for the analysis of the mineral content of small volumes of serum and whole blood samples from healthy individuals. Interday and intraday precision for the mineral content of the blood (250 μl) and serum (250 μl) samples was measured for eight essential minerals, sodium (Na), calcium (Ca), magnesium (Mg), potassium (K), iron (Fe), zinc (Zn), copper (Cu), and selenium (Se) by plasma spectrometric methods and ranged from 0.635 – 10.1% relative standard deviation (RSD) for serum and 0.348 – 5.98% for whole blood. A comparison of the determined ranges for ten serum samples and six whole blood samples provided good agreement with literature reference ranges. The results demonstrate that the digestion and analysis methods can be used to reliably measure the content of these minerals, and potentially to add other minerals. PMID:24917052

Acute-phase proteins and cytokines were measured by ELISA in 24 healthy pregnant women undergoing vaginal delivery or Cesarean section. Cord blood samples in addition to maternal blood were collected. SAA and CRP reached the maximum maternal serum levels 24 hours after delivery, while cytokines remained constant over time. SAA and CRP were significantly higher in maternal serum than in newborn's (P<.001 at the moment of delivery. SAA and CRP, regardless of the type of delivery, reproduce the common pattern observed in most inflammatory conditions. Proinflammatory cytokine serum levels do not mirror the increase in SAA and CRP levels.

    Full Text Available Serum levels of organochlorine pesticides (OCP were measured in agricultural workers from Rio de Janeiro State, Brazil. Blood samples from 26 volunteers (24 males, 02 females, 17-60 years old were taken in October 1997. OCP residues (op'DDT pp'DDT, pp'DDD, pp'DDE, aldrin, dieldrin, endrin, heptachlor, heptachlor-epoxide, alpha-, beta- and gamma-hexachlorocyclohexane, and hexachlorobenzene were analyzed by gas chromatography with an electron capture detector. Tests detected pp'DDE in 16 out of 26 samples, but pp'DDE concentration exceeded 1.4 µg/L (i.e. 1.8, 2.4 and 4.4 µg/L in only 3 of these. beta-HCH was found in 6 (23.1% out of 26 samples. In one sample beta-HCH did not exceed 1.4 µg/L, but in the remaining samples concentrations ranged from 1.4 to 5.3 µg/L. The percentage of positive pp'DDE samples increased from the youngest (£29 yrs: 30.0% to the oldest age group (³ 40 yrs: 100%. A similar trend was found for beta-HCH contamination (£ 29 yrs: 0%; 30-39 yrs: 20.0%; ³40 yrs: 66.7%. Dieldrin (3.7 µg/L was found in only one sample. No other OCP residue was found in the samples. Serum concentrations of OCPs found in this study are comparable to levels reported for the non-occupationally exposed population in Brazil and elsewhere.

    Full Text Available Fructooligosaccharide (FOS is a prebiotic, becoming apparent for its therapeutic role for diseased conditions like CHD, hypertension, diabetes and obesity. CHD and hypertension are one of the most prevalent NCD’s encountered in diabetic adults. Present study aims to assess the effect of FOS supplementation in type 2 diabetic adults on their lipemic, biophysical parameters and gut microflora parameters. A cross-sectional study was designed with 65 adult type 2 diabetics enrolled from Health clinic of The M.S. University of Baroda, Gujarat. All the subjects were randomly divided into two groups control and experimental. The experimental group was given 10 g of fructooligosaccharide and compared with the controls for lipemic parameters, hypertension and fecal counts in terms of lactic acid bacteria, bifidobacteria and enteric pathogen. Eight week supplementation of FOS resulted in an appreciable reduction in serum TC, TG and LDL levels by 10%, 4.9% and 7.8% respectively. A significant reduction (p<0.05 in systolic blood pressure was also observed as a result of FOS supplementation in the experimental group. A decline was seen in TC/HDL, LDL/HDL and non-HDL by 10.4%, 7.6% and 6.6% respectively (p<0.05, p<0.001. Gut microbiota values exhibited a significant increment in fecal log10 counts of Lactic acid bacteria and bifidobacteria by 9.3% and 10.9% respectively (p<0.001 while a significant reduction by 4.8% (p<0.001 was observed for Enteric pathogen. These outcomes revealed an efficacy of FOS in reducing serum lipid parameters, systolic BP and improving the gut microbiota in type 2 diabetic adults

  1. Apoptosis-related deregulation of proteolytic activities and high serum levels of circulating nucleosomes and DNA in blood correlate with breast cancer progression

    International Nuclear Information System (INIS)

    As cell-free circulating DNA exists predominantly as mono- and oligonucleosomes, the focus of the current study was to examine the interplay of circulating nucleosomes, DNA, proteases and caspases in blood of patients with benign and malignant breast diseases. The concentrations of cell-free DNA and nucleosomes as well as the protease and caspase activities were measured in serum of patients with benign breast disease (n = 20), primary breast cancer (M0, n = 31), metastatic breast cancer (M1, n = 32), and healthy individuals (n = 28) by PicoGreen, Cell Death Detection ELISA, Protease Fluorescent Detection Kit and Caspase-Glo®3/7 Assay, respectively. Patients with benign and malignant tumors had significantly higher levels of circulating nucleic acids in their blood than healthy individuals (p = 0.001, p = 0.0001), whereas these levels could not discriminate between benign and malignant lesions. Our analyses of all serum samples revealed significant correlations of circulating nucleosome with DNA concentrations (p = 0.001), nucleosome concentrations with caspase activities (p = 0.008), and caspase with protease activities (p = 0.0001). High serum levels of protease and caspase activities associated with advanced tumor stages (p = 0.009). Patients with lymph node-positive breast cancer had significantly higher nucleosome levels in their blood than node-negative patients (p = 0.004). The presence of distant metastases associated with a significant increase in serum nucleosome (p = 0.01) and DNA levels (p = 0.04), and protease activities (p = 0.008). Our findings demonstrate that high circulating nucleic acid concentrations in blood are no indicators of a malignant breast tumor. However, the observed changes in apoptosis-related deregulation of proteolytic activities along with the elevated serum levels of nucleosomes and DNA in blood are linked to breast cancer progression

    Pyometra is a life-threatening reproductive disorder that affects the uterus of female dogs. This study was designed to identify the possible indicators of uterine inflammation by comparing C-reactive protein (CRP), serum amyloid A (SAA), and haptoglobin (Hp) concentrations in uterine arterial and peripheral venous blood in bitches with open- and closed-cervix pyometra. CRP, SAA, and Hp concentrations were higher in bitches with closed-cervix pyometra irrespective of the site of blood collection. Higher acute-phase protein concentrations were observed in peripheral compared with uterine arterial blood in bitches with closed-cervix pyometra, whereas the levels were comparable in dogs with open-cervix pyometra. Our results indicate that mean acute-phase protein concentrations differ according to pyometra type/severity and blood source and suggest the possible use of peripheral blood levels of CRP, SAA, and Hp to monitor inflammation during the course of pyometra.

    Freeze-drying, or lyophilization, has shown great promise in addressing many of the logistical challenges of storing and preserving red blood cells (RBCs). A crucial part of any RBC lyophilization protocol is the primary drying temperature, which affects the sample drying rate and the dried cake's ability to form a stable glassy solid. Primary drying is most efficient just below the temperature at which the porous structure of the cake begins to collapse, known as the cake collapse temperature. In this short report, we utilize freeze-drying microscopy to examine the effects of human serum albumin (HSA) and hematocrit on the cake collapse temperature. Increasing the hematocrit from 0% to 20% significantly raised the cake collapse temperature from - 37.8°C to -34.8°C. Addition of 5% HSA to a 20% hematocrit RBC suspension further increased the cake collapse temperature to -20.4°C. These data provide a basis for future study of the relationship between cake collapse and overall cell survival, with the object of building a clinically-viable RBC lyophilization protocol.

    Full Text Available Background and Objective: Carbohydrates are considered as the major source of energy in physical activity. Studies show that consumption of carbohydrate foods before exercise can balance blood glucose and free fatty acids and increase athletes’ performance. In this study , we compared the effect of three kinds of foods with different glycemic indices on blood glucose (BG and serum free fatty acids (FFA in cycling ,male athletes. Material and Methods: In this clinical trial, 21 members of national cycling team randomly allocated to three equal groups of glucose (low glycemic index ، lentil (low glycemic index and potato (high glycemic index. First, Fasting blood samples (5ml were obtained to measure BG and FFA . Then the subjects were asked to eat their foods. After 45 mins of rest, they pedaled with maximal oxygen consumption VO2max for two hours and again their blood samples were taken to compare with the levels of before interventions. Results: Glucose consumption resulted in a significant decrease in FFA level after 2 hours of pedaling (P = 0.01 but no significant change in BG level. Plasma glucose was higher after eating lentil than that of potato (P<0.05, but it was not true for FFA level of both groups. Conclusion: Based on the results, the pre-exercise use of low glycemic index (lentil compared to high glycemic index (potato can better lead to increased blood glucose during exercise.

    Background: Fetal bovine serum (FBS) is widely used in cell culture laboratories, risk of zoonotic infections and allergic side effects create obstacles for its use in clinical trials. Therefore, an alternative supplement with proper inherent growth-promoting activities is demanded. Objective: To find FBS substitute, we tested human umbilical cord blood serum (hUCS) for proliferation of human umbilical cord matrix derived mesenchymal stem cells (hUC-MSCs) and human bone marrow-derived mesenchymal cells (hBM-MSCs). Materials and Methods: Umbilical cord blood of healthy neonates, delivered by Caesarian section, was collected and the serum was separated. hUC-MSCs and hBM-MSCs were isolated and characterized by assessment of cell surface antigens by flow cytometry, alkaline phosphatase activity and osteogenic/adipogenic differentiation potential. The cells were then cultured in Iscove's Modified Dulbecco's Medium (IMDM) by conventional methods in three preparations: 1- with hUCS, 2- with FBS, and 3- without serum supplements. Cell proliferation was measured using WST-1 assay, and cell viability was assessed by trypan blue staining. Results: The cells cultured in hUCS and FBS exhibited similar morphology and mesenchymal stem cells properties. WST-1 proliferation assay data showed no significant difference between the proliferation rate of either cells following hUCS and FBS supplementation. Trypan blue exclusion dye test also revealed no significant difference for viability between hUCS and FBS groups. A significant difference was detected between the proliferation rate of stem cells cultured in serum-supplemented medium compared with serum-free medium. Conclusion: Our results indicate that human umbilical cord serum can effectively support proliferation of hBM-MSCS and hUC-MSCs in vitro and can be used as an appropriate substitute for FBS, especially in clinical studies.

    ObjectiveTo investigate the changes of leptin levels in serum, cord venous blood and placenta and examine the possible relationships among them in women with gestational diabetes mellitus (GDM).Methods This case-control study was performed in 40 women with GDM and 40 normal women. The women with GDM received dietary advice, blood glucose monitoring and insulin treatment when necessary. Maternal serum and venous cord blood leptin, insulin and C-peptide levels were detected by ELISA. The expression level of leptin in placenta was measured by an immunohistochemical method. Results1. Leptin, insulin and C-peptide levels in serum of the women with GDM were significantly higher than those of the normal women (P<0.01,P<0.05, P<0.01). 2. Cord venous blood leptin and insulin in GDM group were significantly higher than in the normal group (P<0.01,P<0.05). No significant difference was found in cord venous blood C-peptide between two groups. 3. The expression of placenta leptin protein was significantly higher in GDM women than in normal women (P<0.01). There were positive correlations between placental leptin, cord venous leptin and insulin, birth weight, ponderal index in GDM women (r=0.37,P<0.05;r=0.39,P<0.05;r=0.53,P<0.01;r=0.54,P<0.01). However, there was no correlation between placental leptin and serum leptin.Conclusion The women with GDM and their fetuses suffer from hyperleptinaemia and hyperinsulinaemia. In the women with GDM, there was disorder in the interaction between leptin and insulin. The GDM women and their fetuses may be prone to insulin resistance and leptin resistance in late pregnancy.

    Full Text Available Background: The fatty acid (FA composition of serum lipids is related to the quality of dietary fat intake. Objective: To investigate the effects of a healthy Nordic diet (ND on the FA composition of serum cholesterol esters (CE-FA and assess the associations between changes in the serum CE-FA composition and blood lipoproteins during a controlled dietary intervention. Design: The NORDIET trial was a 6-week randomised, controlled, parallel-group dietary intervention study that included 86 adults (53±8 years with elevated low-density lipoprotein cholesterol (LDL-C. Serum CE-FA composition was measured using gas chromatography. Diet history interviews were conducted, and daily intake was assessed using checklists. Results: Food and nutrient intake data indicated that there was a reduction in the intake of fat from dairy and meat products and an increase in the consumption of fatty fish with the ND. The levels of saturated fatty acids in cholesterol esters (CE-SFA 14:0, 15:0, and 18:0, but not 16:0, showed a significant decrease after intake of ND compared to the control diet (p<0.01. Also, a significant increase in serum 22:6n – 3 was observed compared with the control diet (p<0.01. The changes in CE-SFA 14:0, 15:0, and 18:0 correlated positively with changes in LDL-C, HDL-C, LDL-C/HDL-C, ApoA1, and ApoB (p<0.01, respectively, whereas the changes in polyunsaturated fatty acids in cholesterol esters (CE-PUFA 22:6n – 3 were negatively correlated with changes in the corresponding serum lipids. Conclusions: The decreased intake of saturated fat and increased intake of n-3 PUFA in a healthy ND is partly reflected by changes in the serum CE-FA composition, which are associated with an improved serum lipoprotein pattern.

  9. Effect Of Garlic Oil On Haematological Parameters, Blood Respiratory Functions And Serum Testosterone In Male Rats Exposed To An Electromagnetic Field

    International Nuclear Information System (INIS)

    This study was conducted to investigate the biological effects of exposure to an electromagnetic field (EMF, 900 MHz) emitted from mobile base station antenna for 4 weeks on haematological parameters, respiratory function of blood (blood gases, acid-base status) and oxygen equilibrium curves beside the levels of serum testosterone and possible protective role of garlic oil (250 mg/kg b.w/day for 4 weeks) in male albino rats. The results revealed significant reductions in haemoglobin (Hb) contents, total leucocytes (WBC) count, mean corpuscular volume (MCV) and haematocrit value (Hct %) in rats exposed to EMF (GI). These reductions have been ameliorated by garlic oil treatment (GII). Significant increases in oxygen partial pressure (PO2) were observed in arterial (a) and alveolar (A) blood. These increases were reduced by garlic oil treatment. The percent oxygen saturation (% O2 sat) was significantly decreased in arterial while it was increased significantly in venous blood in both treated groups. There was a significant reduction in carbon dioxide partial pressure (PCO2) in the arterial blood after exposure to EMF (GI) which was decreased by garlic oil treatment. Significant reductions were recorded in arterial blood pH, bicarbonate (HCO-3), total carbon dioxide (TCO2) and arterial and venous blood base excess (BE). These reductions were decreased by garlic oil treatment in GII. The blood oxygen equilibrium curves (OEC) of (GI) and (GII) were shifted to the right compared to that of control group with non-significant increases in P50 . The level of serum testosterone was highly significantly decreased in GI. This reduction was decreased in garlic oil treated group (GII). It can be concluded that garlic oil has a protective role against the hazardous effects of EMF.

    The sources of variations that may cause physiological differences between blood serum biochemistry parameters of bulls have not been investigated in detail. Aim of the present study was to establish influence of different periods of the year and the age of breeding bulls on parameters of antioxidative status and oxidative stress in their serum and to correlate these monitored variables. Research was performed on two groups, each comprising 9 Simmental bulls: a younger group (YB) (aged 2-4 years) and older one (OB) (aged 5-10 years). Blood samples for biochemical analyses were collected from jugular vein in cold (CP) and warm periods (WP) of the year. Reduced glutathione (GSH), uric acid (UA), total protein (TP), albumin (ALB), thiobarbituric acid reactive substance (TBARS), and protein carbonyl content (PCC) serum concentration were determined, as well as activities of selenium-dependent glutathione peroxidase (Se-GSH-Px), total superoxide dismutase (TSOD), manganese superoxide dismutase (MnSOD), copper-zinc superoxide dismutase (CuZnSOD) and catalase (CAT). Serum values of SeGSH-Px, MnSOD, UA and TP in OB were significantly higher compared to those in YB during CP of the year. Significantly higher PCC concentration in serum of YB and OB were established in CP of the year than in WP. TBARS serum concentration in YB was significantly higher in comparison to that in OB during CP of the year. It can be concluded that both OB and YB show a great sensitivity to climate condition alterations during CP in comparison to WP of the year and that YB show even greater sensitivity. PMID:27288340

    Full Text Available To investigate the IgG content and its variations in uterine fluid (UF during the estrous cycle of the cow and to compare them with those of the blood serum (S, six pairs of serum and UF samples for each phase of the cycle selected out of 240 bovine genital tracts and blood samples were collected from Urmia abattoir. The UF samples were collected by gentle scraping of the endometrium using a curette after uterine incision and their IgG content and those of the serum were measured by single radial immuno-diffusion (SRID assay. Serum IgG values (Mean ± SEM were generally higher than the UF values throughout the cycle except for di-estrus (S: 38.50 ± 0.90, UF: 51.60 ± 2.10 mg mL-1, in which the highest values were observed in UF samples. In met-estrus the difference was not significant (S: 34.80 ± 1.80mg mL-1, UF: 30.80 ± 5.20 mg mL-1, however, in estrus the mean UF IgG value (12.50 ± 1.10 mg mL-1 was lower than that of the serum (31.30 ± 1.20 mg mL-1. In pro-estrus, the lowest values (S: 27.80 ± 1.30 mg mL-1, UF: 9.10 ± 1.50 mg mL-1 were obtained. The results showed a lower IgG values in the bovine UF than those of the serum in the follicular phase of the cycle, while in di-estrus the UF IgG content was the highest, suggesting some IgG production in the uterus at this phase.

  16. Fluoride Levels in Urine, Blood Plasma and Serum of People Living in an Endemic Fluorosis Area in the Thar Desert, Pakistan

    International Nuclear Information System (INIS)

    Fluoride (F/sup -/) levels in the urine, blood plasma and serum samples of people living in a village in the Thar Desert have been analysed where fluorosis is endemic and groundwater contains fluoride as high as 9.76 mg/L. Average values of fluoride levels in these human specimens i.e. urine, blood plasma and serum have been found to be 12.98 mg/L, 0.61 mg/L and 0.75 mg/L, respectively. These values are much higher than the normal values reported from other parts of the world. It was observed that urinary fluoride levels increase with age of an individual but with an insignificant correlation (r = 0.116), however, fluoride levels in plasma and serum samples did not vary considerably with age in male and female subjects. It has been found that after the age of 50 years the urinary fluoride decreases with its concomitant increase in serum fluoride level. Since groundwater is the only available source of water for human consumption and it contains higher fluoride (av. 7.09 mg/L) than WHO limit (1.5 mg/L), therefore, it is the main cause of fluorosis in the area.

    Background: Trace elements and specially minerals are critical for the development of fetus. Many minerals are transferred to the fetus for fetal stores in the latter part of the pregnancy. It has been shown that various trace elements such as Zinc, Iron, Calcium and Magnesium are metabolically interrelated and there is alteration in their concentration during pregnancy. Beyond pregnancy is associated with increased demand of all the nutrients and deficiency of any of these could affect pregnancy, delivery and outcome of pregnancy. Aim: To study the levels of trace elements namely zinc, iron, magnesium and calcium in maternal and umbilical cord blood and their association with pregnancy outcome. Methods: Sixty pregnant women in Zabol, Iran were selected from those who had registered their names for the prenatal care and who had followed up till the 3rd trimester of pregnancy ending in child birth. Biochemical parameters analyzed with help of the biochemical laboratory. Data were analyzed by SPSS software. Results: The mean biochemical profile such, serum calcium, magnesium, zinc and iron in the pregnant women were as follow: in the 1st trimester 8.3, 1.9, 74.9 and 74.4 µg/dl respectively; in the 2nd trimester 8.5, 1.9, 73.1 and 79.3 µg/dl, respectively; in the 3rd trimester 8.6, 1.9, 68.4, and 82.2 µg/dl, respectively. In the umbilical cord blood, the mean serum calcium, magnesium, zinc and iron were 8.5, 1.9, 84.1, and 89.8 µg/dl, respectively. The mean serum calcium and magnesium during the three trimesters of pregnancy were not significantly different from that in the umbilical cord blood, while the mean serum zinc and iron in the umbilical cord blood were significantly different (p<0.05) in the three trimester of pregnancy. The mean birth weight of neonates was 3.1 kg and 12% of neonates showed low birth weight. Our findings showed that, except magnesium, the profile of other biochemical variables, namely, calcium, zinc and iron in the umbilical cord blood

    Training nonhuman animals in captivity for participation in routine husbandry procedures is believed to produce a lower stress environment compared with undergoing a general anesthetic event for the same procedure. This hypothesis rests largely on anecdotal evidence that the captive subjects appear more relaxed with the trained event. Blood markers of physiological stress responses were evaluated in 4 captive grizzly bears (Ursus arctos horribilis) who were clicker-trained for blood collection versus 4 bears who were chemically immobilized for blood collection. Serum cortisol and immunoglobulin A (IgA) and plasma β-endorphin were measured as indicators of responses to stress. Plasma β-endorphin was not different between the groups. Serum IgA was undetectable in all bears. Serum cortisol was undetectable in all trained bears, whereas chemically immobilized bears had marked cortisol elevations (p < .05). The highest cortisol elevations were found in 2 bears with extensive recent immobilization experience. These findings support the use of positive reinforcement training for routine health procedures to minimize anxiety. PMID:26847149

    Objective:To determine the presence of Babesia bovis (B. bovis) in large ruminants in southern Punjab and its effect on hematological and serum biochemical profile of host animals. Methods:Blood samples were collected from 144 large ruminants, including 105 cattle and 39 buffaloes, from six districts in southern Punjab including Multan, Layyah, Muzaffar Garh, Bhakar, Bahawalnagar and Vehari. Data on the characteristics of animals and herds were collected through questionnaires. Different blood (hemoglobin, glucose) and serum (ALT, AST, LDH, cholesterol) parameters of calves and cattle were measured and compared between parasite positive and negative samples to demonstrate the effect of B. bovis on the blood and serological profile of infected animals. Results:27 out of 144 animals, from 5 out of 6 sampling districts, produced the 541-bp fragment specific for B. bovis. Age of animals (P=0.02), presence of ticks on animals (P=0.04) and presence of ticks on dogs associated with herds (P=0.5) were among the major risk factors involved in the spread of bovine babesiosis in the study area. ALT concentrations were the only serum biochemical values that significantly varied between parasite positive and negative cattle. Conclusions:This study has reported for the first time the presence of B. bovis in large ruminant and the results can lead to the prevention of babesiosis in the region to increase the livestock output.

  1. Effect of low level Doses of fast neutrons on the toxicity of snake venom through measuring some biophysical properties of blood serum of rats

    International Nuclear Information System (INIS)

    This study was conducted to investigate the effect of low level doses of fission neutrons from Cf 252 source on sublethal doses (low medium) of snake venom cerastes cerastes by injecting albino eats with unirradiated or irradiated venom and measuring the biophysical alterations in the blood serum of the rats. The biophysical properties of the total serum proteins were studied through measuring their dielectric relaxation and the electric conductivity in the frequency range 0.1→5 MHz at 4 degree C. The absorption spectra of the extracted total serum protein were also measured. The results indicated that there are pronounced changes in the molecular constructions of the total serum protein such as the molecular radii, shape, the relaxation time and dielectric increment for the rats injected with unirradiated venom but for the rats injected with irradiated venom (3x108 n/cm2) corresponding values approach the control value. These changes in the molecular constructions of the total serum protein indicate changes in its biochemical properties. This fact was revealed in a previous work, where the irradiation with the fast neutrons were found to decrease the toxicity of the venom

  2. Identification of muscle-specific microRNAs in serum of muscular dystrophy animal models: promising novel blood-based markers for muscular dystrophy.

    Full Text Available Duchenne muscular dystrophy (DMD is a lethal X-linked disorder caused by mutations in the dystrophin gene, which encodes a cytoskeletal protein, dystrophin. Creatine kinase (CK is generally used as a blood-based biomarker for muscular disease including DMD, but it is not always reliable since it is easily affected by stress to the body, such as exercise. Therefore, more reliable biomarkers of muscular dystrophy have long been desired. MicroRNAs (miRNAs are small, ∼22 nucleotide, noncoding RNAs which play important roles in the regulation of gene expression at the post-transcriptional level. Recently, it has been reported that miRNAs exist in blood. In this study, we hypothesized that the expression levels of specific serum circulating miRNAs may be useful to monitor the pathological progression of muscular diseases, and therefore explored the possibility of these miRNAs as new biomarkers for muscular diseases. To confirm this hypothesis, we quantified the expression levels of miRNAs in serum of the dystrophin-deficient muscular dystrophy mouse model, mdx, and the canine X-linked muscular dystrophy in Japan dog model (CXMD(J, by real-time PCR. We found that the serum levels of several muscle-specific miRNAs (miR-1, miR-133a and miR-206 are increased in both mdx and CXMD(J. Interestingly, unlike CK levels, expression levels of these miRNAs in mdx serum are little influenced by exercise using treadmill. These results suggest that serum miRNAs are useful and reliable biomarkers for muscular dystrophy.

    Optimal dietary protocols for the athletic canine are often defined by requirements for endurance athletes that do not always translate into optimal dietary interventions for all canine athletes. Prior research studying detection dogs suggests that dietary fat sources can influence olfaction; however, as fat is added to the diet the protein calories can be diminished potentially resulting in decreased red blood cell counts or albumin status. Optimal macronutrient profile for detection dogs may be different considering the unique work they engage in. To study a calorically low protein: high fat (18:57% ME), high protein: high fat (27:57% ME), and high protein: low fat (27:32% ME) approach to feeding, 17 dogs were provided various diets in a 3 × 3 cross over design. Dogs were exercised on a treadmill and blood was taken pre-exercise, immediately post-exercise, 10- and 20-min post-exercise to assess complete blood count, serum chemistry, blood gases, and cortisol; as well as rectal and core body temperature. Exercise induced a decrease in serum phosphorus, potassium, and increases in non-esterified fatty acids and cortisol typical of moderate exercise bouts. A complete and balanced high protein: high-fat diet (27:57% ME) induced decreases in serum cortisol and alkaline phosphatase. Corn oil top dressed low protein: high-fat diet (18:57% ME) induced a slightly better thermal recovery than a complete and balanced high protein: high fat diet and a high protein: low fat (27%:32% ME) diet suggesting some mild advantages when using the low protein: high fat diet that warrant further investigation regarding optimal protein and fat calories and thermal recovery.

    The isotopic composition of blood serum Cu has been investigated as a potential parameter for the diagnosis and prognosis of liver cirrhosis. Serum samples from supposedly healthy women (reference population) and from a group of female patients suffering from liver cirrhosis of different etiologies were analysed. The procedure for isolation of serum Cu and the measurement protocol for its isotopic analysis by multi-collector inductively coupled plasma-mass spectrometry (MC-ICP-MS) were evaluated. Significant differences in the isotopic composition of Cu were observed between the reference population and the patients. A wide spread in δ(65)Cu was observed within the cirrhosis population and δ(65)Cu seems to be linked to the severity of the disease. Patients with end-stage liver disease showed a significantly lighter serum Cu isotopic composition. Many clinical parameters used for the diagnosis and monitoring of liver diseases, i.e. the levels of aspartate aminotransferase, De Ritis ratio, prothrombin and international normalized ratio, albumin, bilirubin, Na and C-reactive protein, correlate well with the δ(65)Cu values, as did the ceruloplasmin level and the ceruloplasmin/Cu concentration ratio. The isotopic composition of serum Cu appears to reveal the synthetic and hepatocellular function of the liver synergistically with inflammation and fluid retention in the cohort studied. A relevant relationship was also observed between δ(65)Cu and scores of mortality risk, such as the Model for End-stage Liver Disease (MELD) and MELD-Na. Thus, the isotopic composition of serum Cu shows potential as a new approach for the prognosis of liver disease, and although further investigation is required, for evaluation of the mortality risk in end-stage liver disease and prioritization of liver transplants.

    The effect of intrathecally administered magnesium sulphate on serum levels of magnesium, sodium, potassium, calcium and blood gas variables was studied in a rat model. Magnesium sulphate given intrathecally has previously been shown to produce segmental spinal blockade with no permanent neurological damage. The previous studies, however, had not investigated the possible systemic effects of the magnesium sulphate. The serum magnesium level increased significantly at 1 and 2 h after the intrathecal injection of both 6.3% and 12.6% magnesium sulphate (6.3%: 28% at 1 h, 24% at 2 h; 12.6%: 22% at 1 h, 16% at 2 h). These changes were not as great as occurred when the same dose of magnesium sulphate was administered intravenously. In all cases, the serum magnesium had returned to normal by 24 h. There were no significant changes in calcium, sodium or potassium levels, nor in arterial blood gas variables. These results show that intrathecally administered magnesium sulphate has little effect on electrolyte homeostasis.

    Full Text Available Background & Objective: The regular exercise training is known as a preventive and adjuvant therapy in inflammatory diseases such as cancer. The aim of this study was to determine the effect of the aerobic training on IL-10 and IL-8 levels and the count of white blood cells (WBC in women with breast cancer. Material & Methods: The statistical society of the present study included Kerman women with breast cancer. Forty patients with breast cancer were randomly divided into two groups: exercise (n = 20 and control (n = 20. The exercise group performed the endurance training for 8 weeks with the intensity between 40 to 55 percent of the target heart rate. Twenty four hours before the first session and 48 hours after the last session of the exercise protocol, blood samples were taken from both groups and then IL-10 and IL-8 levels in serum were measured by ELISA via a Boster kit. Results: The results of the present study showed that 8 weeks of the endurance exercise training did not significantly increase the IL-10 (P=0.113 serum level, but increased the WBC count (p=0.019 and decreased the serum level of IL-8 (p=0.03 significantly. Conclusion: According to the results of the present study, regular endurance training via decreasing the inflammatory factors can be considered as an effective factor along with other therapies in improving breast cancer.

    Full Text Available Background: Most lantern mantles contain low levels of radioactive thorium. Although radioactive lantern mantles present a minimal radiation health hazard, it is generally believed when inhaled or ingested, it can be dangerous. The purpose of this study was to assess the effect of short term exposure to radioactive lantern mantle on serum cortisol level and blood count.Materials and Methods: This experimental study was conducted in 2007-2009 in the school of medicine of Rafsanjan University of Medical Sciences. Twenty eight rats were divided randomly into two groups of 14 animals each. The first group was exposed to 600 mg burned radioactive lantern mantle powder (activity of 800Bq for 24 hours and inhaled radon released from mantles. The second group was exposed to non-radioactive lantern mantle powder at the same interval. Paired t-test was used to evaluate the difference in the means of cortisol and blood cell count in both groups. P<0.05 was considered as the significance level.Results: Short term exposure of animals to radioactive lantern mantle powder led to a statistically significant decreased cortisol level, while no statistically significant decrease was found in animals that were exposed to non-radioactive mantle powder. Furthermore, a significant reduction was shown in post-exposure counts of WBC in the case group.Conclusions: Despite alteration of serum cortisol level, this study could not show stimulatory effects in some blood counts

    Many studies have demonstrated the efficacy of folic acid (FA) supplementation in prevention of neural tube defects (NTDs), although the extent of NTDs varies among individuals of different races and ethnic origin. China is a multi-ethnic country with no standard practice for FA-fortified food. Milk is consumed by women, but little is known about the effects of milk on folate concentration in maternal blood and neonatal umbilical cord blood in Han and Mongolian women after stopping taking the supplement for a month and five month, respectively. The objective of this study was to determine whether only daily consumption of liquid milk can increase the blood folate concentration in pregnant women and whether there are differences in blood folate concentrations between Han and Mongolian women after cessation of FA supplementation. Of the 4052 women enrolled in the parallel group design study. Three thousand five hundred and twenty-six women had confirmed pregnancies and were randomized to receive liquid milk or not until delivery. Women who consumed the liquid milk had significantly increased serum folate concentrations at 16 and 32 weeks of gestation as well as cord blood at birth compared to control groups in both ethnic groups. Infants born to women drinking milk also had better the term birth weight and height, which may be related to the increased concentration of folate. In conclusion, daily consumption of milk can increase the serum folate concentration in pregnant Han and Mongolian women in China (differences in the efficacy of FA and milk supplementation) and may enhance birth outcomes.

    Metabolite profiling by NMR of body fluids is increasingly used to successfully differentiate patients from healthy individuals. Metabolites and their concentrations are direct reporters of body biochemistry. However, in blood plasma the NMR-detected free-metabolite concentrations are also strongly affected by interactions with the abundant plasma proteins, which have as of yet not been considered much in metabolic profiling. We previously reported that many of the common NMR-detected metabolites in blood plasma bind to human serum albumin (HSA) and many are released by fatty acids present in fatted HSA. HSA is the most abundant plasma protein and main transporter of endogenous and exogenous metabolites. Here, we show by NMR how the two most common fatty acids (FAs) in blood plasma - the long-chain FA, stearate (C18:0) and medium-chain FA, myristate (C14:0) - affect metabolite-HSA interaction. Of the set of 18 common NMR-detected metabolites, many are released by stearate and/or myristate, lactate appearing the most strongly affected. Myristate, but not stearate, reduces HSA-binding of phenylalanine and pyruvate. Citrate signals were NMR invisible in the presence of HSA. Only at high myristate-HSA mole ratios 11:1, is citrate sufficiently released to be detected. Finally, we find that limited dilution of blood-plasma mimics releases HSA-bound metabolites, a finding confirmed in real blood plasma samples. Based on these findings, we provide recommendations for NMR experiments for quantitative metabolite profiling.

    Objective The aim of our study was to investigate the relationship among age, sex, body mass index (BMI), serum lipid profiles, blood glucose (BG), and bone mineral density (BMD), making an assessment of the risk of osteoporosis. Materials and methods A total of 1,035 male and 3,953 female healthy volunteers (aged 41–95 years) were recruited by an open invitation. The basic information, including age, sex, height, weight, waistline, hipline, menstrual cycle, and medical history, were collected by a questionnaire survey and physical examination. Serum lipid profiles, BG, postprandial blood glucose, and glycosylated hemoglobin were obtained after 12 hours fasting. BMD in lumbar spine was measured by dual-energy X-ray absorptiometry scanning. Results The age-adjusted BMD in females was significantly lower than in males. With aging, greater differences of BMD distribution exist in elderly females than in males (P7.0 mmol/L was lower than in people with BG of ≤7.0 mmol/L (P<0.001). People with serum high-density lipoprotein cholesterol levels of ≥1.56 mmol/L had a greater prevalence of osteoporosis compared with high-density lipoprotein cholesterol ≤1.55 mmol/L. Logistic regression with odds ratios showed that no association was found among total cholesterol, triglyceride, low-density lipoprotein cholesterol, glycosylated hemoglobin, postprandial blood glucose and BMD. Conclusion The present study further confirmed that factors such as age, sex, weight, BMI, high-density lipoprotein cholesterol, and diabetes are significant predictors of osteoporosis in the Chinese people.

    Full Text Available The aim of the present study was to comparatively evaluate hemogram, blood serum components and anatomopathologic alterations in commercial layers experimentally challenged with an attenuated vaccine candidate strain (SG∆cobS∆cbiA and other two pathogenic strains (SGDcobS and SGNalr of Gallinarum (SG. In total, 280 commercial layers were randomly divided into 4 groups (G1, G2, G3 and G4. At five days of age, birds from groups G1 received approximately 107 colony forming units (CFU of SGDcobS; meanwhile birds from group G2 and G3 received the same dose of SGNalr and SG∆cobS∆cbiA, respectively. Birds from G4 were not infected. At 24 hours before (DBI and 24 hours after (1 DAI, and three (3 DAI, five (5 DAI, seven (7 DAI ten (10 DAI, and fifteen (15 DAI days after the infection, 10 birds of each group were humanely killed and blood samples collected to hematological and serum tests. Samples of liver, spleen, thymus, bursa of Fabricius, kidney and heart were also collected for the histological examination. Birds inoculated with SGDcobS and SGNalr showed similar alterations in hemogram, blood serum components and anatomopathologic exams. On the other hand, the exams of birds inoculated with SG∆cobS∆cbiA strain were similar to those of the uninfected birds. However, changes could be noticed in levels of uric acid and cholesterol during the course of the infection of birds from G3. Decrease in levels of light IgG 3 DAI was also observed in birds from this group. Pyknosis in kidney cells was a microscopic alteration found in birds from G3. Further studies must be done to verify if these alterations will not interfere in the performance of the vaccinate birds with SG∆cobS∆cbiA strain.

    Reestablishment of testicular normal temperature after testicular heat stress is unknown and its effect varies widely. The aim of this study was to investigate the impact of scrotal insulation (IN) on testicular temperature and its relation to semen quality and testosterone blood serum concentration. For this, 33 rams were used; 17 submitted to IN for 72 hours (using bags involving the testes) and 16 not submitted to IN (control group). The experiment was performed between August and December 2013 in Pirassununga, Brazil (21°56″13″ South/47°28'24″ West). Seminal characteristics, testosterone blood serum concentration, rectal temperature (RT), respiratory frequency, scrotal superficies mean temperature (SSMT), and eye area mean temperature (EAMT) were analyzed 7 days before IN and 21, 35, 49, 63, and 90 days afterward. Scrotal superficies mean temperature and EAMT were measured by thermography camera FLIR T620. Testosterone was evaluated by radioimmunoassay. Analysis of variance was used to determine the main effects of treatment, time, and treatment-by-time interaction using PROC MIXED of SAS software adding command REPEAT. Pearson correlation test was used to verify correlation between SSMT, EAMT, RT, and respiratory frequency. Significant difference was considered when P ≤ 0.05. At the end of IN, SSMT was higher (P rams (P = 0.03). Thus, the difference of 1.12 °C between RT and testicular temperature impacts semen quality and testosterone blood serum concentration. Moreover, this study shows that rams can recover testes temperature efficiently toward IN and that infrared thermography is an efficient tool to identify differences on SSMT. PMID:27045627

    During marketing, cattle may be exposed to periods of water deprivation. The impact of water and feed access and health status on the physiological well-being and carcass characteristics of Holstein slaughter cows during preslaughter marketing was studied through analysis of serum components, BW loss percentage, and fresh meat composition. Ninety-one multiparous Holstein cows (609 ± 89 kg mean BW, 2.9 ± 0.5 mean BCS, varying stage of lactation) were purchased over 3 wk in 3 groups (n = 31, 29, and 31) at a terminal market in central Wisconsin. Each cow was screened to determine health status (sick or not sick) and randomly assigned to 1 of 3 water and feed withdrawal treatment pens (AL, ad libitum access to water for 36 h; 18H, 18 h of ad libitum access to water followed by 18 h of water withdrawal; 36H, 36 h of water withdrawal; all 3 treatments included 36 h of feed withdrawal) in a randomized complete block arrangement with repeated measures for serum components. Blood samples were collected by tail venipuncture at 0, 9, 18, 27, and 36 h of each treatment. Ambient temperatures were 1.9 ± 6.2°C during the trial period, which occurred over a 3-wk period in March and April 2007 near Arlington, WI. No difference (P > 0.05) was observed in mean serum cortisol in AL (18.41 ± 2.17 ng/mL) or 36H (22.98 ± 2.17 ng/mL). Mean serum glucose was greater (P water and feed access treatment. Based on these results, water and feed withdrawal in lairage should not exceed 18 h during the marketing of Holstein slaughter cows acclimated to springtime conditions to maintain BW, serum component concentrations, and fresh meat composition.

    Among all plasma proteins human serum albumin (HSA) is the most studied one as it is the main transport protein and can bind a wide variety of ligands especially fatty acids (FAs). The concentration of FAs bound to HSA in human blood plasma differs by three times under abnormal conditions (fasting, physical exercises or in case of social important diseases). In the present study a surfactant sodium dodecyl sulfate (SDS) was used to simulate FAs binding to HSA. It was shown that the increase of Tyr fluorescence of human blood plasma due to SDS addition can be completely explained by HSA-SDS complex formation. Binding parameters of SDS-HSA complex (average number of sites and apparent constant of complex formation) were determined from titration curves based on tyrosine (Tyr) fluorescence.

    AIM: To explore the relationship between gastric and intestinal microcirculatory impairment and inflammatory mediators released in rats with acute necrotizing pancreatitis (ANP).METHODS: A total of 64 rats were randomized into control group and ANP group. ANP model was induced by injection of 5% sodium taurocholate under the pancreatic membrane.Radioactive biomicrosphere technique was used to measure the gastric and intestinal tissue blood flow at 2 and 12 h after the induction of ANP, meanwhile serum phospholipase A2 (PLA2) activities and interleukin-1β levels were determined. Pathologic changes in pancreas, gastric and intestinal mucosae were studied. RESULTS: The gastric blood flow in ANP group (0.62±0.06 (P<0.01) at 2 and 12 h after induction of ANP. The intestinal blood flow in ANP group (0.80±0.07 and (P<0.01). Serum PLA2 activities (94.29±9.96 and 103.71± 14.40) U/L and IL-1β levels (0.78±0.13 and 0.83±0.20) μg/L in ANP group were higher than those in control group (65.27±10.52 and 66.63±9.81) U/L, (0.32±0.06 and 0.33±0.07) μg/L (P<0.01). At 2 and 12 h after introduction of the model, typical pathologic changes were found in ANP. Compared with control group, the gastric and intestinal mucosal pathologic changes were aggravated significantly (P<0.01) at 12 h after induction of ANP. Gastric and intestinal mucosal necrosis, multiple ulcer and hemorrhage occurred.CONCLUSION: Decrease of gastric and intestinal blood flow and increase of inflammatory mediators occur simultaneously early in ANP, both of them are important pathogenic factors for gastric and intestinal mucosal injury in ANP.

    This study aimed to investigate the independent and joint association of blood pressure (BP), homocysteine (Hcy), and fasting blood glucose (FBG) levels with brachial-ankle pulse wave velocity (baPWV, a measure of arterial stiffness) in Chinese hypertensive adults.The analyses included 3967 participants whose BP, Hcy, FBG, and baPWV were measured along with other covariates. Systolic BP (SBP) was analyzed as 3 categories (SBP < 160 mmHg; 160 to 179 mmHg; ≥ 180 mmHg); Hcy as 3 categories (< 10 μmol/L; 10 to 14.9 μmol/L; ≥ 15.0 μmol/L) and FBG: normal (FBG < 5.6 mmol/L), impaired (5.6 mmol/L ≤ FBG < 7.0 mmol/L), and diabetes mellitus (FBG ≥ 7.0 mmol/L). We performed linear regression analyses to evaluate their associations with baPWV with adjustment for covariables.When analyzed individually, BP, Hcy, and FBG were each associated with baPWV. When BP and FBG were analyzed jointly, the highest baPWV value (mean ± SD: 2227 ± 466 cm/s) was observed in participants with FBG ≥ 7.0 mmol/L and SBP ≥ 180 mmHg (β = 432.5, P < 0.001), and the lowest baPWV value (mean ± SD: 1692 ± 289 cm/s) was seen in participants with NFG and SBP < 160 mmHg. When Hcy and FBG were analyzed jointly, the highest baPWV value (2072 ± 480 cm/s) was observed in participants with FBG ≥ 7.0 mmol/L and Hcy ≥ 15.0 μmol/L (β = 167.6, P < 0.001), while the lowest baPWV value (mean ± SD: 1773 ± 334 cm/s) was observed in participants with NFG and Hcy < 10 μmol/L.In Chinese hypertensive adults, SBP, Hcy, and FBG are individually and jointly associated with baPWV.Our findings underscore the importance of identifying individuals with multiple risk factors of baPWV including high SBP, FBG, and Hcy.

    A high relative molecular mass (M(r)) component which confers serum resistance on gonococci has been purified about 300-fold from a dialysed sonicate of human blood cells. Serum resistance conferred by the high M(r) factor (RIF), like that induced by cytidine-5' monophospho-N acetyl neuraminic acid (CMP-NANA), decreased when gonococci were incubated with neuraminidase. Also, the resistance-inducing activities of both high M(r) RIF and CMP-NANA were inhibited by CMP and inactivated at pH 4.0. These activities were not additive but synergistic. Neuraminidase decreased the activity of high M(r) RIF but not CMP-NANA. In tests with 14C CMP-NANA and gonococcal lipopolysaccharide, no sialyltransferase activity was detected, even in highly active samples of high M(r) RIF under conditions in which low activities of rat liver sialyltransferase were readily detected. Conversely, rat liver sialyltransferase was neither active in the RIF assay nor able to enhance the RIF activity of CMP-NANA. Nevertheless, high M(r) RIF greatly enhanced the sialyltransferase activity of a gonococcal extract; this enhancement suggests an explanation for the synergism between CMP-NANA and high M(r) RIF in inducing serum resistance in gonococci.

    The aim of the study was to characterize the systemic immune and metabolic alterations in the blood serum of growing pigs in response to a dietary supplementation with 4% of dried chicory roots. This was achieved by examining the influence of the experimental diet on serum protein changes especially these related with immunology and lipid metabolism. Serum proteins with the isoelectric point ranging from pH 3.0 to 10.0 were separated using high resolution two-dimensional electrophoresis. As a result, we found that experimental diet triggered significant changes in 37 protein spots. Of these, 14 were up-regulated, whereas 23 showed down-regulation. Of 37 significantly altered protein spots, 24 were successfully identified, representing 14 distinct gene products. Implementation of the dried chicory roots into the diet of growing pigs caused a significant down-regulation of apolipoprotein C-II complement component C6, C-reactive protein, CD14 antigen, C4b binding protein α and β chains, and fibrinogen. Piglets fed experimental diet had similar IgA, IgG and IgM concentrations, although the level of IgM tended to be lower compared to the control group. It is concluded that diet supplemented with 4% of dried chicory root may exert anti-inflammatory properties and affect lipid metabolism in growing pigs. PMID:25716964

    A simple and sensitive flow injection spectrophotometric method is reported for the determination of vitamin E using potassium ferricyanide-Fe(Ⅲ detection system. In the presence of vitamin E, Fe(Ⅲ/ferricyanide reduces. The in situ reduced ions are then reacted with unreduced portion of ferricyanide/Fe(Ⅲ to make soluble Prussian blue, which is monitored at absorption wavelength of 735 nm. Linear calibration graph was obtained in the concentration range of 0.1-40 μg mL-1. The relative standard deviations (n = 4) were in the range of 1.1-3.6%, with limits of detection (3 s blank) of 0.04 μg mL-1. The proposed method allowed 12 injections h-1. The method is applied to determine vitamin E in Pharmaceuticals, infant milk and blood serum samples using hexane extraction with the recoveries in the range of 93 ± 3 to 97.5 ± 4%. The method is validated using certified reference materials SRM 968c for blood serum samples.

    Effects of L-carnitine administration via drinking water on growth performance, carcass traits, blood serum parameters and abdominal fatty acid composition of ducks was examined. One hundred day-old Turkish native duck chicks were divided into two groups, each with five replicates and given the same diets with 0 and 200 mg/l carnitine chlorhydrate via drinking water. The study lasted 8 weeks, with the first 4 weeks as a starter and the last 4 weeks as grower period. At the end of the study five ducks were randomly selected from each subgroup for slaughter. Growth performance parameters of ducks were not affected significantly by L-carnitine administration. Live weight, daily weight gain, cumulative feed consumption and average feed conversion efficiency were found to be 1490 and 1621 g, 26.0 and 28.1 g, 5386 and 5662 g, 3.75 and 3.54 kg/kg in the control and in the carnitine groups respectively. L-carnitine administration did not effect carcass traits and serum cholesterol, total lipid, triglyceride and glucose levels. Total saturated fatty acid content of abdominal fat significantly decreased, mono- and polyunsaturated fatty acid content were not affected by L-carnitine administration. In conclusion, L-carnitine administration by drinking water did not affect growth performance, carcass traits and blood parameters in ducks.

    An atomic absorption spectrometric (AAS) method has been developed for determining microg/L levels of Sb in samples of water and blood. The AAS method is based on the concept of stabilized temperature platform furnace atomization (STPF) realized through the use of a transversely heated graphite atomizer (THGA) furnace, longitudinal Zeeman-effect background correction, and matrix modification with palladium nitrate-magnesium nitrate-nitric acid. The method of standard additions is not mandatory. The detection limit (3 standard deviations of the blank) is 2.6 microg Sb/L for the water, red blood cells (RBCs), and serum samples. Data are presented on the degree of accuracy and precision. The THGA-AAS method is simple, fast, and contamination-free because the entire operation from sampling to AAS measurement is carried out in the same tube. The method has been applied to the determination of Sb in some leachate tap water samples derived from a static copper plumbing system containing Sn/Sb solders, and in small samples (0.5 ml) of RBCs and serum derived from rats given Sb-supplemented drinking water.

Methods: the following groups were studied; (1 normal rats treated with saline; (2 normal rats treated with L-cysteine (18 mg/kg; (3 rats exposed to EMF for 21 days and treated with the vehicle (saline during the exposure period; (4 rats exposed to EMF for 21 days and treated with L-cysteine (18 mg/kg orally, 3 times per week during the exposure period; (5 rats exposed to EMF for 21 days and treated with the vehicle (saline during the exposure period and for 45 days after exposure; (6 rats exposed to EMF for 21 days and treated with L-cysteine (18 mg/kg orally, 3 times per week during the exposure period and for 45 days after exposure; Results: in rats exposed to low frequency EMF for 21 days (group2, marked increase in aspartate aminotransferase (AST and alanine aminotransferase (ALT activities in serum was observed. Plasma bilirubin level was raised. Meanwhile, significant decrease in plasma glucose levels occured after exposure to EMF. No significant changes were observed in haemoglobin level, red blood cells or total leucocytic count noted in rats exposed to EMF. The elevations in serum bilirubin, AST and ALT levels were reduced to near normal values in rats given L-cysteine druing the 21 days of exposure (group3. On the other hand, in rats examined 45 days after the end of the exposure period (group 3, no significant alterations were noted as regards bilirubin, AST, ALT and glucose levels in serum. Conclusions: these results suggest that (1 exposure to low frequency EMF of 50 Hz is associated with some degree of liver injury reflected in increased leakage of hepatoceular enzymes into plasma as well as an increase in serum bilirubin; (2 these alterations can be ameliorated by the administration of L-cysteine, as well as; (3

    Human beings working or living near an industrial site where toxic chemicals such as As, Hg, Cd, Cu, Mn, Pb, Zn and or their compounds are used or indiscriminately discharged into the environment, are constantly exposed to such chemicals via ingestion (drinking or eating), dermal contact or inhalation (breathing). However, in developing countries such as Ghana, limited data on levels of the aforementioned chemicals in whole blood and serum of human beings as a result of exposure to the aforementioned chemicals from mining communities and non-mining communities is preventing effective policy formulation to protect human health. Hence, this study was undertaken to measure the levels of the aforementioned toxic chemicals in whole blood and serum of 300 resident adults from mining (Tarkwa Nsuaem Municipality Assembly (TNMA) and Prestea Huni Valley District (PHVD)) and non-mining (Cape Coast Metropolis) communities in Ghana, using neutron activation analysis (NAA). Blood samples were taken from 200 resident adults (105 males and 95 females) from mining and 100 resident adults (60 males and 40 males) from non-mining communities in the study area following the completion of an informed consent and the issuance of ethical clearance by the Ghana Health Service Ethical Committee. The mean concentrations for As, Hg, Cd, Cu, Mn, Pb and Zn in whole blood of residents from mining communities were as follows: 38 ± 320 μg/L, 63 ± 0.23 μg/L, 303 ± 117 μg/L, 3300 ± 953, 195 ± 90 μg/L, 28 ± 14 μg/L and 1405 ± 458 μg/L, respectively; while the levels of measured toxic chemicals in the serum of resident adults from mining communities were as follows: 65 ± 14 μg/L, 358 ± 22 μg/l, 134 ± 12 μg/L, 3590 ± 254 μg/L, 401 ± 113 μg/L, 58 ± 5.8 μg/L and 49 ± 31 μg/L, respectively, for As, Hg, Cd, Cu, Mn, Pb and Zn and were found to have exceeded the permissible WHO guideline values.

    Chlorine is a public health concern and potential threat due to its high reactivity, ease and scale of production, widespread industrial use, bulk transportation, massive stockpiles and history as a chemical weapon. This work describes a new, sensitive and rapid stable isotope dilution method for the retrospective detection and quantitation of two chlorine adducts. The biomarkers 3-chlorotyrosine (Cl-Tyr) and 3,5-dichlorotyrosine (Cl2-Tyr) were isolated from the pronase digest of chlorine exposed whole blood, serum or plasma by solid-phase extraction (SPE), separated by reversed-phase HPLC and detected by tandem mass spectrometry (MS-MS). The calibration range is 2.50-1,000 ng/mL (R2 ≥ 0.998) with a lowest reportable limit (LRL) of 2.50 ng/mL for both analytes, an accuracy of ≥93% and an LOD of 0.443 ng/mL for Cl-Tyr and 0.396 ng/mL for Cl2-Tyr. Inter- and intra-day precision of quality control samples had coefficients of variation of ≤10% and ≤7.0%, respectively. Blood and serum samples from 200 healthy individuals and 175 individuals with chronic inflammatory disease were analyzed using this method to assess background levels of chlorinated tyrosine adducts. Results from patients with no known inflammatory disease history (healthy) showed baseline levels of Cl2-Tyr. Patients with inflammatory disease had baseline levels of Cl2-Tyr. Blood exposed to 2.02 ppm chlorine gas for 15 min produced 941 ng/mL Cl-Tyr and 223 ng/mL Cl2-Tyr. This high-throughput method has been developed and analytically validated for the diagnosis of human exposure to chlorine. PMID:26977104

    Full Text Available Vitamin B12, a co-factor in methyl-group transfer, is important in maintaining DNA (deoxycytidine methylation. Using two independent assays we examined the effect of vitamin B12-deficiency (plasma vitamin B12<148 pmol/L on DNA methylation in women of childbearing age. Coagulated blood clot DNA from vitamin B12-deficient women had significantly (p<0.001 lower percentage deoxycytidine methylation (3.23±0.66%; n = 248 and greater [3 H]methyl-acceptance (42,859±9,699 cpm; n = 17 than DNA from B12-replete women (4.44±0.18%; n = 128 and 26,049±2,814 cpm; n = 11 [correlation between assays: r = -0.8538; p<0.001; n = 28]. In contrast, uncoagulated EDTA-blood cell pellet DNA from vitamin B12-deficient and B12-replete women exhibited similar percentage methylation (4.45±0.15%; n = 77 vs. 4.47±0.15%; n = 47 and [3 H]methyl-acceptance (27,378±4,094 cpm; n = 17 vs. 26,610±2,292 cpm; n = 11. Therefore, in simultaneously collected paired blood samples, vitamin B12-deficiency was associated with decreased DNA methylation only in coagulated samples. These findings highlight the importance of sample collection methods in epigenetic studies, and the potential impact biological processes can have on DNA methylation during collection.

    Full Text Available Background. Organism’s lipid peroxidation is one of the most often examined and known physiological process evoked by free radicals. It concerns oxidation reaction of unsaturated fatty acid and/or other lipids leading to lipid oxidation products (LOP, which as a result of further changes generate among others the malondialdehyde molecules. The aim of the work was an estimation if raw or cooked kale addition to rat’s diet infl uences antioxidant defense effi ciency in their organisms in comparison to rats fed with standard AIN-93G diet. Material and methods. The experiment was conducted with 36 Wistar strain, male rats over 21 days. The rats were divided into 3 groups (each 12 stuck which were fed with: standard diet AIN-93G (2 groups, AIN-93G diet with 10% addition of raw kale (2 groups, and AIN-93G with 10% addition of cooked lyophilised kale. The total content of polyphenols (FC method and antioxidant activity (ABTS+• were previously determined in raw and then in cooked kale. On the 20th day of experiment, half of rats (6 stuck of each kind of the diet were injected intraperitoneally by the solution of paraquat (PQ in physiological salt to evoke the oxidative stress. The next day animals were stunned and blood from their hearts was sampled. In the obtained serum, the levels of lipid oxidation products (LOP and malondialdehyde (MDA were assessed. Results. It was observed that in blood serum of rats fed with modifi ed diet with raw and cooked lyophilised kale addition the lipid oxides level was lower in comparison to control group fed with standard diet (p < 0.05. It was found that intoxication with paraquat caused growth of MDA and LOP levels in blood serum of all rats in comparison to not intoxicated groups but that growth was the lowest in group fed diet with cooked kale addition. Conclusion. Diet with kale, both raw and cooked, effi ciently inhibited the lipid peroxidation process in rats’ organisms, ongoing during natural metabolism

  20. Experimental toxicity studies of cadmium in human blood serum in Jordan, using inductively coupled plasma (ICP) techniques

    International Nuclear Information System (INIS)

    A spectrometric inductively coupled plasma-emission atomic technique was used for the determination of cadmium in human blood samples. An organized system for the collection and handling of cadmium of human blood samples was applied. Also procedures for collection, preparation, analysis and quality control were suggested. The aim of this is to assist scientists world wide to produce comparable data which will be useful on regional, national and international scale. The guideline in this study is directed to (Cd) which ranged from non detectable to low measurable values. Limit of detection of ICP-EAS was in the range from 0.3 ppb to 40 ppb. Accuracy was evaluated by analysis of the certified reference materials, using a standard addition method. One hundred and three human blood samples were analyzed; the population for the study had ages between nineteen and twenty years. Samples were collected at a specific time during a typical study day and analyzed for cadmium. The results of analysis showed a low measurable and non-detectable concentrations of (Cd), which is within and below the limits recommended by World health Organization (WHO). (author)

  1. A defined, feeder-free, serum-free system to generate in vitro hematopoietic progenitors and differentiated blood cells from hESCs and hiPSCs.

    Full Text Available Human ESC and iPSC are an attractive source of cells of high quantity and purity to be used to elucidate early human development processes, for drug discovery, and in clinical cell therapy applications. To efficiently differentiate pluripotent cells into a pure population of hematopoietic progenitors we have developed a new 2-dimensional, defined and highly efficient protocol that avoids the use of feeder cells, serum or embryoid body formation. Here we showed that a single matrix protein in combination with growth factors and a hypoxic environment is sufficient to generate from pluripotent cells hematopoietic progenitors capable of differentiating further in mature cell types of different lineages of the blood system. We tested the differentiation method using hESCs and 9 iPSC lines generated from different tissues. These data indicate the robustness of the protocol providing a valuable tool for the generation of clinical-grade hematopoietic cells from pluripotent cells.

    Objective: To observe the anti-inflammatory effect of cerivastatin in a mouse model of vascular injury and its cholesterol-lowering effect. Methods: We developed a mouse model of vascular remodeling induced by polyethylene cuff placement and determined the anti-inflammatory effects of cerivastatin in wild mice. Cerivastatin was given by Alzet micro-osmotic minipumps implanted intraperitoneally at the same time as cuff placement at doses of 0.1 mg/kg, 0.5 mg/kg and 1 mg/kg per day, respectively for 2 weeks after cuff placement. The insufficient doses of Cerivastatin to lower serum cholesterol and systolic blood pressure through the neointimal formation and BrdU index were investigated in mouse femoral injury artery induced by cuff-placement. Results: There was a little change in serum cholesterol by the treatment with cerivastatin, the cross-sectional area of intima of injured femoral artery was significantly increased, the neointima formation was significantly increased by the cuff-induced vascular injury at day 14. The neointimal formation and BrdU index were inhibited in the 1 mg/kg cerivastatin, but not in the 0.1 mg/kg and 0.5 mg/kg cerivastatin. Furthermore, 1 mg/kg of cerivastatin significantly inhibited the expression of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) without lowering serum cholesterol.Conclusions: These results suggest that cerivastatin can inhibit vascular inflammation and the proliferation of vascular smooth muscle cells (VSMCs) through its lipid-lowering independent action. Such effects of cerivastatin may be an important mechanism, by which it prevents the development of atherosclerotic lesions.

    In recent years, there has been a growth in reports of antiepileptic drugs (AEDs) being misused on their own or in combination with other drugs of abuse in a variety of toxicological case types such as drug abuse, suicide, overdose and drug facilitated crime. To our knowledge, there are no simultaneous quantification methods for the analysis of the most commonly encountered AEDs in postmortem whole blood and clinical plasma/serum samples at the same time. A simple, accurate and cost-effective liquid chromatography-tandem mass spectrometric (LC-MS-MS) method has been developed and validated for the simultaneous quantification of carbamazepine (CBZ) and its metabolite CBZ-10,11-epoxide, eslicarbazepine acetate, oxcarbazepine and S-licarbazepine as a metabolite, gabapentin, lacosamide, lamotrigine, levetiracetam, pregabalin, phenobarbital, phenytoin and its metabolite 5-(p-hydroxyphenyl)-5-phenylhydantoin, retigabine (ezogabine) and its metabolite N-acetyl retigabine, rufinamide, stiripentol, topiramate, tiagabine, valproic acid, vigabatrin and zonisamide in postmortem whole blood, serum and plasma which would be suitable for routine forensic toxicological analysis and therapeutic drug monitoring. All AEDs were detected and quantified within 17 min without endogenous interferences. The correlation coefficient (R(2)) was >0.995 for all AEDs with accuracy ranging from 90 to 113% and precision <13% for all analytes. The recovery ranged from 70 to 98%. No carryover was observed in a blank control injected after the highest standard and the matrix effect was acceptable and ranged from 90 to 120%. The method has been successfully verified using authentic case samples that had previously been quantified using different methods. PMID:25217536

    Oropharyngeal cancer is a significant public health issue in the world. The incidence of oropharyngeal cancer has been increased among people who have habit of chewing smokeless tobacco (SLT) in Pakistan. The aim of present study was to evaluate the concentration of nickel (Ni) in biological samples (whole blood, serum) of oral (n = 95) and pharyngeal (n = 84) male cancer patients. For comparison purposes, the biological samples of healthy age-matched referents (n = 150), who consumed and did not consumed SLT products, were also analyzed for Ni levels. As the Ni level is very low in biological samples, a preconcentration procedure has been developed, prior to analysis of analyte by flame atomic absorption spectrometry (FAAS). The Ni in acid-digested biological samples was complexed with ammonium pyrrolidinedithio carbamate (APDC), and a resulted complex was extracted in a surfactant Triton X-114. Acidic ethanol was added to the surfactant-rich phase prior to its analysis by FAAS. The chemical variables, such as pH, amounts of reagents (APDC, Triton X-114), temperature, incubation time, and sample volume were optimized. The resulted data indicated that concentration of Ni was higher in blood and serum samples of cancer patients as compared to that of referents who have or have not consumed different SLT products (p = 0.012-0.001). It was also observed that healthy referents who consumed SLT products have two to threefold higher levels of Ni in both biological samples as compared to those who were not chewing SLT products (p < 0.01).

    The effects of sub-chronic exposure to cadmium (Cd) on the blood glutathione, serum zinc and on the kidney histological organisation in rats as well as the possible protective role of zinc (Zn) are the object of this study. For this purpose, 60 male Wistar rats (8 weeks old) were divided into three groups: the first group was exposed to Cd in the form of CdCl(2), administered in five doses (each of 0.4 mg Cd/kg b.w.) on days 5, 10, 15, 20 and 25, giving a total dose of 2mg Cd/kg b.w., i.p.; the second group was simultaneously exposed to Zn and Cd with the same timeline and the same doses of Cd as the first group but with, in addition, injections of Zn in the form of ZnCl(2), administered in doses of 0.8 mg Zn/kg b.w., giving a total dose of 4 mg Zn/kg b w, i.p.; a control group received 0.5 mL of physiological saline in an identical manner. Intoxication with Cd was followed by a significant decrease in blood glutathione, increase in oxidized glutathione as well as histological damage in kidneys. Pre-treatment with Zn exhibited a protective role against Cd toxicity with a significant decrease in serum zinc content. This fact may be explained by an excessive use of zinc in metallothionein synthesis as a cadmium detoxification agent.

    1985-10-01

    Full Text Available Levels of plasma cyclic AMP, serum immunoreactive insulin (IRI, serum c-peptide immunoreactivity (CPR and blood sugar (BS were determined 0, 15, 30, 45 and 60 min after a glucagon injection (0.01 mg per kg body weight in normal controls, patients with acute hepatitis and liver cirrhosis. Plasma cyclic AMP responses to glucagon in liver disease patients varied widely in peak value, and only in patients with fulminant hepatitis and decompensated liver cirrhosis with poor prognosis was the response suppressed. The peak response of BS was found significantly later in liver cirrhosis patients than in normal controls. IRI and CPR responses to glucagon were lower in acute hepatitis patients than in normal controls and liver cirrhosis patients. IRI levels and their sum were also lower in acute hepatitis patients, although CPR levels were not significantly different. Thus, the ratio of the sum of CPR from 0 to 60 min to that of IRI was significantly higher in acute hepatitis, indicating impaired pancreatic secretion of insulin to glucagon stimulation as well as increased uptake of insulin by the liver in acute hepatitis.

    In 34 pure breed Arabian horses divided into four groups (Gr. I--10 pregnant mares, Gr. II--7 barren mares, Gr. III--10 foals born in 1981, Gr. IV--7 foals born in 1982) seasonal changes in total blood serum protein, its electrophoretic fractions and the activity of AspAT and AlAT were studied. Seasonal cyclicity was found in all groups in the amount of total serum proteins, and alpha 2- and beta 1-globulin fractions. Cyclicity was found in the level of albumin and activity of AspAT in three groups, not Gr. II, and in gamma-globulin, not Gr. IV. beta 2-globulin and AlAT cyclicity was found in two groups and alpha 1-globulin cyclicity was found only in Gr. II. Out of nine indices studied, cyclicity was found in eight of them in pregnant mares, Gr. I; in seven in older foals, Gr. III; in six in the young foals, Gr. IV; and in five in barren mares, Gr. II.

    The article presents data on the effect of the combined action of food and muscular load on the level of hydrolytic enzymes in blood serum of healthy young people 18-22 years old, with various levels of adaptation to the effects of physical activity. The first group (n = 8) of the examined persons were high-qualified athletes developing their speed and power qualities in anaerobic energetic regime (Greco-Roman wrestling, sambo, judo). The second group (n = 8) were athletes developing endurance in aerobic energetic regime (skiers, track and field athletes--stayers, biathletes). The control group (n = 8) consists of non-athletes. The content of hydrolytic enzymes: pepsinogen-1, pepsinogen-2, the activity of pancreatic alpha-amylase, lipase were defined by ELISA. The content and activity of ferments were defined in blood serum, taken in the morning fasting and post-prandial period in dynamics after 15, 45, 75 and 105 min after administration of the test breakfast (100 g of ground boiled beef and 200 ml of unsweetened tea) in a state of relative physiological rest and after the veloergometric exercise muscular load (at the level of 60-70% of maximal oxygen consumption) during an hour (in 7-14 days). Multidirectional changes of concentration of investigated enzymes in the postprandial period among examined were defined in the conditions of relative physiological rest and under the action of the muscular tension. For groups of athletes higher alpha-amylase and lipase blood activity were characteristic both in a state of physiological rest and under the action of muscular load. It was also determined that after the muscular tension there was an increase in activity of alpha-amylase at 75 min and lipases at 15 min relative to background indicators at non-athletes. For the athletes from the second group the increase (p < 0.01) relative to background data of activity as alpha-amylase as lipase on an empty stomach was noted. However postprandial (15-45 min) alpha-amylase (p

    Metabolites and their concentrations are direct reporters on body biochemistry. Thanks to technical developments metabolic profiling of body fluids, such as blood plasma, by for instance NMR has in the past decade become increasingly accurate enabling successful clinical diagnostics. Human Serum Albumin (HSA) is the main plasma protein (˜60% of all plasma protein) and responsible for the transport of endogenous (e.g. fatty acids) and exogenous metabolites, which it achieves thanks to its multiple binding sites and its flexibility. HSA has been extensively studied with regard to its binding of drugs (exogenous metabolites), but only to a lesser extent with regard to its binding of endogenous (non-fatty acid) metabolites. To obtain correct NMR measured metabolic profiles of blood plasma and/or potentially extract information on HSA and fatty acids content, it is necessary to characterize these endogenous metabolite/plasma protein interactions. Here, we investigate these metabolite-HSA interactions in blood plasma and blood plasma mimics. The latter contain the roughly twenty metabolites routinely detected by NMR (also most abundant) in normal relative concentrations with fatted or non-fatted HSA added or not. First, we find that chemical shift changes are small and seen only for a few of the metabolites. In contrast, a significant number of the metabolites display reduced resonance integrals and reduced free concentrations in the presence of HSA or fatted HSA. For slow-exchange (or strong) interactions, NMR resonance integrals report the free metabolite concentration, while for fast exchange (weak binding) the chemical shift reports on the binding. Hence, these metabolites bind strongly to HSA and/or fatted HSA, but to a limited degree because for most metabolites their concentration is smaller than the HSA concentration. Most interestingly, fatty acids decrease the metabolite-HSA binding quite significantly for most of the interacting metabolites. We further find

    Knowledge is limited on the efficacy of hindgut-fermentable dietary fibre to reduce blood, bile and body tissue cholesterol levels. In three experiments with growing pigs the effects of different kinds and levels of bacterially fermentable fibre (BFS) on cholesterol metabolism were examined. Various diets calculated to have similar contents of metabolizable energy were supplied for complete fattening periods. In the first experiment, a stepwise increase from 12 to 20% BFS was performed by supplementing diets with fermentable fibre from sugar beet pulp (modelling hemicelluloses and pectin). Beet pulp, rye bran (modelling cellulose) and citrus pulp (pectin) were offered either independently or in a mixture in the second experiment. These diets were opposed to rations characterized in carbohydrate type by starch either mostly non-resistant (cassava) or partly resistant (maize) to small intestinal digestion. The third experiment was planned to explore the interactions of BFS from citrus pulp with fat either through additional coconut oil/palm kernel oil blend or full-fat soybeans. In all experiments the increase of the BFS content was associated with a constant (cellulose) or decreasing (hemicelluloses, pectin) dietary proportion of non-digestible fibre. In experiment 1 an inverse dose-response relationship between BFS content and cholesterol in blood serum and adipose tissue as well as bile acid concentration in bile was noted while muscle cholesterol did not respond. In experiment 2 the ingredients characterized by cellulose and hemicelluloses/pectin reduced cholesterol-related traits relative to the low-BFS-high-starch controls whereas, except in adipose tissue cholesterol content, the pectinous ingredient had the opposite effect. However, the changes in serum cholesterol mainly affected HDL and not LDL cholesterol. Adipose tissue cholesterol also was slightly lower with partly resistant starch compared to non-resistant starch in the diet. Experiment 3 showed that

    Full Text Available To investigate the effects of daily supplementation with docosahexaenoic acid (DHA on coronary heart disease risks in 38 middle-aged men with hypertension and/or hypercholesterolemia in Scotland, a five-week double-blind placebo-controlled dietary supplementation with either 2 g of DHA or active placebo (1 g of olive oil was conducted. Percent composition of DHA in plasma phospholipids increased significantly in DHA group. Systolic and diastolic blood pressure and heart rate decreased significantly in DHA group, but not in placebo group. High-density lipoprotein cholesterol (HDL-C increased significantly, and total cholesterol (TC/HDL-C and non-HDL-C/HDL-C ratios decreased significantly in both groups. There was no change in TC and non-HDL-C. We conclude that 2 g/day of DHA supplementation reduced coronary heart disease risk factor level improving blood pressure, heart rate, and lipid profiles in hypertensive, hypercholesterolemic Scottish men who do not eat fish on a regular basis.

    Full Text Available The timely supply of newborn calves with optimal quantities of colostrum has a key role in the process of immune protection in the early phase of their lives. Passively acquired antibodies can protect the digestive organs from infection caused by E.coli bacteria, and it seems also from the appearance of diseases of the respiratory tract. These examinations were performed on a cattle farm where bronchopneumonia was one of the most significant health problems, and a group of 39 calves were selected for the investigations. The calves were fed with their mothers’ colostrum after birth, and then with collective milk. Immunoglobulin concentration was determined in blood samples taken during the postcolostral period, with the method using zinc-sulphate. At the age of 40 days, the calves were administered a polyvalent inactivated vaccine, and revaccinated 20 days after that (Vibak, Veterinary Department Subotica. In 74.34% calves, the immunoglobulin G concentration ranged from 26 to 40 g/l. In 25.66% calves, the immunoglobulin concentration was lower, from 8 to 25 g/l. The calves found to have a lower concentration of immunoglobulin in blood contracted bronchopneumonia more frequently, and the outcome of the disease in some cases was mortality, even.

    Full Text Available Although it is recognized that the mechanical stresses associated with physical activity augment bone mineral density and improve bone quality, our understanding of how exercise modulates bone homeostasis at the molecular level is lacking. In a before and after trial involving 43 healthy adults, we measured the effect of six months of supervised exercise training on the spontaneous and phytohemagglutinin-induced production of osteoclastogenic cytokines (interleukin-1α, tumor necrosis factor-α, antiosteoclastogenic cytokines (transforming growth factor-β1 and interleukins 4 and 10, pleiotropic cytokines with variable effects on osteoclastogenesis (interferon-γ, interleukin-6, and T cell growth and differentiation factors (interleukins 2 and 12 by peripheral blood mononuclear cells. We also measured lymphocyte phenotypes and serum markers of bone formation (osteocalcin, bone resorption (C-terminal telopeptides of Type I collagen, and bone homeostasis (25 (OH vitamin D, estradiol, testosterone, parathyroid hormone, and insulin-like growth factor 1. A combination of aerobic, resistance, and flexibility exercises done on average of 2.5 hours a week attenuated the production of osteoclastogenic cytokines and enhanced the production of antiosteoclastogenic cytokines. These changes were accompanied by a 16% reduction in collagen degradation products and a 9.8% increase in osteocalcin levels. We conclude that long-term moderate intensity exercise exerts a favorable effect on bone resorption by changing the balance between blood mononuclear cells producing osteoclastogenic cytokines and those producing antiosteoclastogenic cytokines.

    Rats were fed an irradiated high-moisture diet (KSC-25) with or without access to a water bottle. Physiologic values were compared between these two groups and a group of rats fed a purified diet. Hematologic and serum biochemical values, urine specific gravity, and intestinal enzyme activities were determined from samples collected from the three groups of rats. Sprague Dawley rats (n=32) fed the irradiated high-moisture diet with or without a water bottle were the test animals. Rats (n=16) fed an irradiated purified diet and water provided via a water bottle were the control group. The purified diet formulation, modified AIN-76A, is a commonly used purified diet for laboratory rodents. All rats remained alert and healthy throughout the study. A comparison of the physiologic values of rats in this study with reported normal values indicated that all of the rats in the study were in good health. Significant differences (P less than 0.05) of the physiologic values from each rat group are reported.

    The article presents data on the effect of the combined action of food and muscular load on the level of hydrolytic enzymes in blood serum of healthy young people 18-22 years old, with various levels of adaptation to the effects of physical activity. The first group (n = 8) of the examined persons were high-qualified athletes developing their speed and power qualities in anaerobic energetic regime (Greco-Roman wrestling, sambo, judo). The second group (n = 8) were athletes developing endurance in aerobic energetic regime (skiers, track and field athletes--stayers, biathletes). The control group (n = 8) consists of non-athletes. The content of hydrolytic enzymes: pepsinogen-1, pepsinogen-2, the activity of pancreatic alpha-amylase, lipase were defined by ELISA. The content and activity of ferments were defined in blood serum, taken in the morning fasting and post-prandial period in dynamics after 15, 45, 75 and 105 min after administration of the test breakfast (100 g of ground boiled beef and 200 ml of unsweetened tea) in a state of relative physiological rest and after the veloergometric exercise muscular load (at the level of 60-70% of maximal oxygen consumption) during an hour (in 7-14 days). Multidirectional changes of concentration of investigated enzymes in the postprandial period among examined were defined in the conditions of relative physiological rest and under the action of the muscular tension. For groups of athletes higher alpha-amylase and lipase blood activity were characteristic both in a state of physiological rest and under the action of muscular load. It was also determined that after the muscular tension there was an increase in activity of alpha-amylase at 75 min and lipases at 15 min relative to background indicators at non-athletes. For the athletes from the second group the increase (p enzyme activity on an empty stomach its increase can be occurred in the postprandial period. Lipase activity changed in groups of athletes unidirectionally

    Full Text Available The purpose of this study was to investigate the effects of two weeks of detraining on somephysical fitness indexes and lactate dehydrogenase (LDH and creatine phosphokinase (CPKenzymes in blood serum of elite taekwondo players. Sixteen elite male taekwondo players withthe averages of age of 18/43 ± 1/20 years; weight 64/49 ± 3/03 kg and years of experience 6/46± 1/36 years were selected voluntarily based on interviews and questionnaires and all of themwere participated in taekwondo training for four weeks equally. Then the subjects were dividedrandomly into an experimental and control groups. The experimental group had a two-week detraining;while the control group continued its training program. To calculate of anaerobicpower and speed (physical fitness indexes were used consecutive vertical jumps (Ergojumptest for 30 seconds and speed 40 yards test in two phases (Before and after of detraining. Bloodsamples to determine the desired enzymes were taken in before and after of detraining following12 to 14 hours of being empty-stomached. Data was analyzed via dependent and independent ttestin significant level P ≥ 0.05. The results of this study have demonstrated that two weeks ofdetraining caused insignificantly decrease of anaerobic power (P = 0/057 and significantly decreaseof speed (P = 0/001 in taekwondo players. Also it was observed that the levels of CPKand LDH blood have reduced significantly (P = 0/001 after tow weeks of detraining. Based theabove finding; it can be claimed that two weeks of detraining have a negative effect on speedand levels of CPK and LDH blood in taekwondo players.

    Cecropia obtusifolia and Marrubium vulgare have been widely used in Mexican traditional medicine for the control of type 2 diabetes. In order to evaluate the clinical effect produced by the aqueous extract from these species on type 2 non-controlled diabetes mellitus, a total of 43 outpatients were included. Based on the European NIDDM (policy group) criteria, only patients with poor response to the conventional treatment were selected. All patients maintained their medical treatment and also received a prepared infusion of the dry leaves of the plant treatment for 21 days. In a double-blind manner, the patients were randomly grouped as follows: 22 patients were treated with C. obtusifolia and 21 with M. vulgare. The fasting blood glucose values were reduced by 15.25% on patients treated with C. obtusifolia, while cholesterol and triglycerides were decreased by 14.62% and 42.0%, respectively (ANOVA pvulgare, the plasma glucose level was reduced by 0.64% and cholesterol and triglycerides by 4.16% and 5.78%, respectively. When the results were compared between groups, significant differences in glucose and cholesterol diminution were found. The obtained results showed that the infusion prepared with the leaves of C. obtusifolia (containing 2.99+/-0.14mg of chlorogenic acid/g of dried plant) produced beneficial effects on carbohydrate and lipid metabolisms when it was administered as an adjunct on patients with type 2 diabetes with poor response to conventional medical treatment.

    Prunus divaricata (Alloocheh) is a small tree cultivating in Iran, Middle East and central Asia. Prunus genus has many species with anti-oxidant, anti-hyperlipidemia and anti-hyperglycemia effects. In the present study the anti-diabetic and anti-hyperlipidemic effects of P. divaricata fruits were examined in normal and streptozotocin (STZ)-induced diabetic rats. Both groups, control and reference rats received normal saline and glibenclamide respectively. Test groups were treated with Prunus freeze dried juice (PFDJ, 200, 400, 800 mg/kg) and Prunus freeze dried extract (PFDE, 100, 200, 400 mg/kg) started at the 3(rd) day of the experiment and continued for 27 days thereafter. Weight changes of animals were checked periodically. Fasting blood glucose (FBG) level as well as serum triglyceride (TG), total cholesterol (TC), high density lipoprotein (HDL) and low density lipoprotein (LDL) cholesterol were determined. Different treatments had no significant effect on body weight increments of normal rats, while in diabetic rats, PFDJ (800 mg/kg) and PFDE (400 mg/kg) opposed with weight loss. In acute phase of experiment (0-8 h of 3(rd) day), none of tested fractions were effective in reducing FBG and serum lipids of normal rats. During the sub-acute phase (13(th) and 30(th) days) however, the greatest test doses of PFDJ (800 mg/kg) and PFDE (400 mg/kg) induced hypoglycema. In diabetic groups, PFDJ and PFDE, at all test doses, could diminish FBG during sub-acute phase of the experiment. In addition, PFDJ and PFDE at most examined doses could diminish TG significantly and they were also effective on cholesterol derivatives in different magnitude. PMID:26339257

    This study was carried out to investigate the effect of dietary supplementation of red ginseng by-product (RGB) on the laying performance, blood biochemistry, and microbial population in laying hens. A total of 120 Hy-Line Brown laying hens (75 weeks old) were randomly allotted to 1 of 3 dietary treatments with 4 replicates per treatment. A commercial-type basal diet was prepared, and 2 additional diets were prepared by supplementing 5.0 or 10.0 g/kg of RGB to the basal diet at the expense of corn. The diets were fed to hens on an ad libitum basis for 4 weeks. There were no differences in feed intake, egg weight, and feed conversion ratio during 4 weeks of the feeding trial. However, hen-day egg production was significantly greater (p<0.05) for the RGB treatment groups than that for the basal treatment group. There were no differences in triglyceride, aspartate aminotransferase, and alanine aminotransferase during the 4-week feeding trial. However, RGB supplementation increased (p<0.05) the serum immunoglobulin G (IgG) and IgM content compared with basal treatment group. The total cholesterol was lower (p<0.05) in the RGB treatments groups than that in the basal treatment group. The intestinal Lactobacillus population was greater (p<0.05) for the RGB treatments groups than that for the basal treatment group. However, the numbers of Salmonella and Escherichia coli were not different among dietary treatments. During the entire experiment, there was no significant difference in egg quality among all the treatments. In conclusion, in addition to improving hen-day production, there were positive effects of dietary RGB supplementation on serum immunoglobulin and cholesterol levels in laying hens. PMID:26954140

    In the present study we introduced a two-dimensional electrophoresis and matrix-assisted laser desorption/ionisation time of flight mass spectrometry-based proteomic workflow to identify proteins that show altered expression as a result of the addition of 2% of water extract of inulin-type fructans to the diet of growing piglets. This analysis allowed us to detect an average of 240 spots per gel with a mass range from 10 to 250 kDa and a pH ranging from 3 to 10. Twenty protein spots were found to show statistically significant differences in their expression. Of these, 7 protein spots were up-regulated, whereas 13 showed down-regulation in response to the experimental diet. In total, 13 spots were identified, representing 8 distinct gene products. The experimental diet caused a significant change in proteins directly or indirectly involved in hemostasis and the innate immune response. Increased levels of fibrinogen along with decreased plasminogen expression may indicate that a fructan-rich diet favours the deposits of fibrin and promotes blood clotting. We also found increased expression of vitronectin and the alpha subunit of the complement component C8 which may protect the host organism against excessive cytolitic activity of the activated complement. The piglets from the experimental group had slightly increased values of IgG and IgA, whereas the IgM level tended to be decreased. The fructan-rich diet did not have any influence on plasma total cholesterol, HDL and LDL cholesterol and triglyceride levels.

    Full Text Available Equine Mesenchymal stromal cells (MSC are commonly transported, chilled or frozen, to veterinary clinics. These MSC must remain viable and minimally affected by culture, transport, or injection processes. The safety of two carrier solutions developed for optimal viability and excipient use were evaluated in ponies, with and without allogeneic cord blood-derived (CB MSC. We hypothesized that neither the carrier solutions nor CB-MSC would elicit measurable changes in clinical, hematological, or biochemical parameters. In 9 ponies (study 1 a bolus of HypoThermosol® FRS (HTS-FRS, CryoStor® CS10 (CS10 or saline was injected IV (n=3/treatment. Study 2, following a one week washout period 5x107 pooled allogeneic CB-MSC were administered IV in HTS-FRS following 24h simulated chilled transport. Study 3, following another one week washout period 5x107 pooled allogeneic CB-MSC were administered IV in CS10 immediately after thawing. Nine ponies received CB-MSCs in study 2 and 3 and three ponies received the cell carrier media without cells. CB-MSCs were pooled in equal numbers from five unrelated donors. In all studies ponies were monitored with physical examination, and blood collection for 7 days following injection. CD4 and CD8 lymphocyte populations were also evaluated in each blood sample.In all three studies, physical exam, complete blood cell count, serum biochemistry, and coagulation panel did not deviate from established normal ranges. Proportions of CD4+ and CD8+ lymphocytes increased at 168h post injection in CB-MSC treatment groups regardless of the carrier solution. Decreases in CD4+/CD8+ double positive populations were observed at 24 h and 72 h in CB-MSC treated animals. There was no difference in viability between CB-MSC suspended in HTS-FRS or CS10.HTS-FRS and CS10 used for low volume excipient injection of MSC suspensions was not associated with short-term adverse reactions. HTS-FRS and CS10 both adequately maintain CB-MSC viability

    Full Text Available Abstract Background Acute appendicitis is one of the most common surgical emergencies. Accurate diagnosis of acute appendicitis is based on careful history, physical examination, laboratory and imaging investigation. The aim of the study is to analyze the role of C-reactive protein (CRP, white blood count (WBC and Neutrophil percentage (NP in improving the accuracy of diagnosis of acute appendicitis and to compare it with the intraoperative assessment and histopathology findings. Materials and methods This investigation was a prospective double blinded clinical study. The study was done on 173 patients surgically treated for acute appendicitis. The WBC, NP, and measurement of CRP were randomly collected pre-operatively from all involved patients. Macroscopic assessment was made from the operation. Appendectomy and a histopathology examination were performed on all patients. Gross description was compared with histopathology results and then correlated with CRP, WBC, and NP. Results The observational accuracy was 87,3%, as compared to histopathological accuracy which was 85.5% with a total of 173 patients that were operated on. The histopathology showed 25 (14.5% patients had normal appendices, and 148 (85.5% patients had acutely inflamed, gangrenous, or perforated appendicitis. 52% were male and 48% were female, with the age ranging from 5 to 59 with a median of 19.7. The gangrenous type was the most frequent (52.6%. The WBC was altered in 77.5% of the cases, NP in 72.3%, and C-reactive protein in 76.9% cases. In those with positive appendicitis, the CRP and WBC values were elevated in 126 patients (72.8%, whereas NP was higher than 75% in 117 patients (67.6%. Out of 106 patients with triple positive tests, 101 (95.2% had appendicitis. The sensitivity, specificity, and positive predictive values of the 3 tests in combination were 95.3%, 72.2%, and 95.3%, respectively. Conclusion The raised value of the CRP was directly related to the severity of

    We investigated the possible pathogenic role of a microRNA (miR-155) in primary immune thrombocytopenia (ITP). We used quantitative real-time PCR to determine the relative expression of miR-155 and SOCS1 (suppressor of cytokine signaling) mRNA in peripheral blood mononuclear cells (PBMCs) from 28 ITP patients and 28 healthy controls. Cytokine plasma levels were determined by ELISA. Possible associations between miR-155 levels and serum cytokine concentrations were assessed using Spearman or Pearson correlation analysis. Seven naive ITP patients were followed and the effects of medical treatment on miR-155 levels were assessed. Compared to healthy controls, ITP patients had increased miR-155 and decreased SOCS1 mRNA levels. ITP patients also had increased plasma IL-17A and decreased IL-4, IL-10 and TGF-β1 levels. miR-155 levels were negatively correlated with platelet counts, SOCS1 mRNA levels, and the plasma levels of IL-4, IL-10 and TGF-β1, but positively correlated with plasma IL-17A levels. Medical treatment for ITP decreased miR-155 levels. Thus, our results suggest that miR-155 might be involved in the pathogenesis of ITP by regulating cytokine profiles, which may be mediated by miR-155 targeting SOCS1. PMID:25413124

    Since several high level natural radiation areas (HLNRAs) exist on our planet, considerable attention has been drawn to health issues that may develop as the result of visiting or living in such places. City of Ramsar in Iran is an HNLRA, and is a tourist attraction mainly due to its hot spas. However, the growing awareness over its natural radiation sources has prompted widespread scientific investigation at national level. In this study, using an ELISA method, the level of expression of three tumor markers known as carcinoembryonic antigen (CEA), prostate-specific antigen (PSA) and carcino antigen 19-9 (CA19-9) in blood serum of 40 local men of Ramsar (subject group) was investigated and compared to 40 men from the city of Noshahr (control group). Noshahr was previously identified as a normal level natural radiation area (NLNRA) that is some 85 km far from Ramsar. According to statistical analysis, there was a significant difference in the levels of PSA and CA19-9 markers between the two groups (p < 0.001) with those of Ramsar being considerably higher. CEA level did not show any difference. Although some of the volunteers tested positive to the markers, they were in good health as confirmed by the physician. Moreover, the high number of positive markers in Noshahr was considerable. Therefore, future study is needed to further validate this result and to determine the level of positivity to tumor markers in both cities.

    Herein, we present a novel strategy for the synthesis of an iron nitride nanoparticles-encapsulated nitrogen-doped graphene (FeN NPs/NG) core-shell hierarchical nanostructure to boost the electrochemical performance in a highly sensitive, selective, reproducible, and stable sensing platform for nicotinamide adenine dinucleotide (NADH). This core-shell hierarchical nanostructure provides an excellent conductive network for effective charge transfer and avoids the agglomeration and restacking of NG sheets, which provides better access to the electrode material for NADH oxidation. The FeN NPs/NG core-shell hierarchical nanostructure demonstrates direct and mediatorless responses to NADH oxidation at a low potential. This material displays a high sensitivity of 0.028μA/μMcm(2), a wide linear range from 0.4 to 718μM, and a detection limit of 25nM with a fast response time of less than 3s. The interferences from common interferents, such as glucose, uric acid, dopamine, and ascorbic acid, are negligible. The fabricated sensor was further tested for the determination of NADH in human blood serum. The resulting high sensitivity, excellent selectivity, outstanding stability, and good reproducibility make the proposed FeN NPs/NG core-shell hierarchical nanostructure as a promising candidate for biomedical applications.

The biochemical parameters of free-radical processes (catalyse and SOD activities, LPO levels) remained unchanged in the inhaling animals. Ethanol or acetone inhalation caused a significant decrease in blood catalyse activity and serum LPO levels. The acetone- and ethanol-induced changes in the activity of ceruloplasmin were heterodirectional. It can be concluded that it is useful to study the biochemical parameters of serum free-radical processes and to employ the findings in the therapy of inhalation toxicomanias.

    This study was conducted to investigate changes in blood enzyme parameters and to evaluate the relationship between insulin-like growth factor-1 (IGF-1), antler growth and body weight during the antler growth of sika deer (Cervus nippon). Serum enzyme activity and IGF-1 concentrations were measured in blood samples collected from the jugular and femoral veins at regular intervals during the antler growth period. Blood samples were taken in the morning from fasted stags (n = 12) which were healthy and showed no clinical signs of disease. Alfalfa was available ad libitum and concentrates were given at 1% of body weight to all stags. The experimental diet was provided at 9 am with water available at all times. There were no significant differences in alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase during antler growth, but alkaline phosphatase concentrations increased with antler growth progression, and the highest alkaline phosphatase concentration was obtained 55 days after antler casting. Serum IGF-1 concentrations measured from blood samples taken from the jugular vein during antler growth, determined that levels of IGF-1 was associated with body weight and antler growth patterns. Serum IGF-1 concentrations were higher at the antler cutting date than other sampling dates. Antler length increased significantly during antler growth (palkaline phosphatase concentration was related to antler growth and both antler growth and body weight were associated positively with IGF-1 concentrations during antler growth.

    Surface glycoconjugates of normal and transformed blood cells are commonly characterized by plant lectins. To infer physiological significance of protein-carbohydrate interactions, mammalian lectins are obviously preferable as research tools. So far, human serum lectins have not been used to assess their binding to immunophenotyped human normal or transformed blood cells. Thus, our study combines two groups of lectins with different specificity from plant and human sources. Besides concanavalin A (ConA) we have isolated the mannose-binding protein and serum amyloid P component from human serum. Especially the mannose-binding protein is believed to play a role in host defence against bacteria and yeast cells with unknown impact on normal and tumor cells. These three lectins establish the first group. In addition to the immunomodulatory mistletoe lectin, whose binding can elicit enhanced cytokine secretion from mononuclear blood cells, we included the beta-galactoside-binding lectin (14 kDa) from human placenta in the second group. The initial series of measurements was undertaken using two-color flow cytometry to determine the phenotype-associated binding (based on cluster designation; CD) of the lectins to blood and bone marrow cells from normal donors and the cell line CEM (T-lymphoblastoid), KG1-A (primitive myeloid leukemia) and Croco II (B-lymphoblastoid). Heterogeneity was apparent for each lectin in the CD-defined cell populations. Significant differences in binding were noted between Viscum album agglutinin (VAA) and other lectins for CD4+ cells from blood and between mannose-binding protein (MBP) and VAA versus 14 kDa, ConA and serum amyloid P component (SAP) for CD19+ cells from bone marrow.(ABSTRACT TRUNCATED AT 250 WORDS)

    Background Tubercular lymphadenitis (TL) is the most common form of extra-pulmonary tuberculosis (TB) consisting about 15–20% of all TB cases. The currently available diagnostic modalities for (TL), are invasive and involve a high index of suspicion, having limited accuracy. We hypothesized that TL would have a distinct cytokine signature that would distinguish it from pulmonary TB (PTB), peripheral tubercular lymphadenopathy (LNTB), healthy controls (HC), other lymphadenopathies (LAP) and cancerous LAP. To assess this twelve cytokines (Tumor Necrosis Factor (TNF)—α, Interferon (IFN) -γ, Interleukin (IL)-2, IL-12, IL-18, IL-1β, IL-10, IL-6, IL-4, IL-1Receptor antagonist (IL-1Ra), IL-8 and TNF-β, which have a role in pathogenesis of tuberculosis, were tested as potential peripheral blood biomarkers to aid the diagnosis of TL when routine investigations prove to be of limited value. Methods and Findings A prospective observational cohort study carried out during 2010–2013. This was a multi-center study with three participating hospitals in Delhi, India where through random sampling cohorts were established. The subjects were above 15 years of age, HIV-negative with no predisposing ailments to TB (n = 338). The discovery cohort (n = 218) had LNTB (n = 50), PTB (n = 84) and HC (n = 84). The independent validation cohort (n = 120) composed of patients with cancerous LAP (n = 35), other LAP (n = 20) as well as with independent PTB (n = 30), LNTB (n = 15) and HC (n = 20). Eight out of twelve cytokines achieved statistical relevance upon evaluation by pairwise and ROC analysis. Further, variable selection using random forest backward elimination revealed six serum biosignatures including IL-12, IL-4, IL-6, IL-10, IL-8 and TNF-β as optimal for classifying the LNTB status of an individual. For the sake of clinical applicability we further selected a three analyte panel (IL-8, IL-10 and TNF-β) which was subjected to multinomial modeling in the independent

    Full Text Available Abstract Background The plasma protein α2-antiplasmin (α2AP is cross-linked to fibrin in blood clots by the transglutaminase factor XIIIa, and in that location retards clot lysis. Competition for this effect could be clinically useful in patients with thrombosis. We hypothesized that fusion of N-terminal portions of α2-antiplasmin to human serum albumin (HSA and production of the chimeric proteins in Pichia pastoris yeast would produce a stable and effective competitor protein. Results Fusion protein α2AP(13-42-HSA was efficiently secreted from transformed yeast and purified preparations contained within a mixed population the full-length intact form, while fusions with longer α2AP moieties were inefficiently secreted and/or degraded. The α2AP(13-42-HSA protein, but not recombinant HSA, was cross-linked to both chemical lysine donors and fibrin or fibrinogen by factor XIIIa, although with less rapid kinetics than native α2AP. Excess α2AP(13-42-HSA competed with α2AP for cross-linking to chemical lysine donors more effectively than a synthetic α2AP(13-42 peptide, and reduced the α2AP-dependent resistance to fibrinolysis of plasma clots equally effectively as the peptide. Native α2AP was found in in vivo clots in rabbits to a greater extent than α2AP(13-42, however. Conclusion In this first report of transfer of transglutamination substrate status from one plasma protein to another, fusion protein α2AP(13-42-HSA was shown to satisfy initial requirements for a long-lasting, well-tolerated competitive inhibitor of α2-antiplasmin predicted to act in a clot-localized manner.

  7. The effect of high level natural ionizing radiation on expression of PSA, CA19-9 and CEA tumor markers in blood serum of inhabitants of Ramsar, Iran

    International Nuclear Information System (INIS)

    Since several high level natural radiation areas (HLNRAs) exist on our planet, considerable attention has been drawn to health issues that may develop as the result of visiting or living in such places. City of Ramsar in Iran is an HNLRA, and is a tourist attraction mainly due to its hot spas. However, the growing awareness over its natural radiation sources has prompted widespread scientific investigation at national level. In this study, using an ELISA method, the level of expression of three tumor markers known as carcinoembryonic antigen (CEA), prostate-specific antigen (PSA) and carcino antigen 19-9 (CA19-9) in blood serum of 40 local men of Ramsar (subject group) was investigated and compared to 40 men from the city of Noshahr (control group). Noshahr was previously identified as a normal level natural radiation area (NLNRA) that is some 85 km far from Ramsar. According to statistical analysis, there was a significant difference in the levels of PSA and CA19-9 markers between the two groups (p < 0.001) with those of Ramsar being considerably higher. CEA level did not show any difference. Although some of the volunteers tested positive to the markers, they were in good health as confirmed by the physician. Moreover, the high number of positive markers in Noshahr was considerable. Therefore, future study is needed to further validate this result and to determine the level of positivity to tumor markers in both cities. -- Highlights: • Expression of three tumor markers was examined in 80 volunteers from Ramsar. • There was a significant difference in the levels of PSA and CA19-9 markers. • Some of the volunteers from the control city of Noshahr also tested positive. • Radiation might have caused an adaptive response in people of Ramsar. • Further study is necessary to re-confirm the positivity to tumor marker

    Full Text Available Objective  To analyze the characteristics of genetic mutations in reverse-transcriptase (RT domain of HBV covalently closed circular DNA (cccDNA in peripheral blood mononuclear cells (PBMCs obtained from chronic hepatitis B (CHB patients with drug-resistant mutations in serum virions during nucleoside/nucleotide analog (NA therapy. Methods  A total of 30 CHB patients admitted to 302 Hospital of PLA from July 2010 to August 2011 were included in this study. All the patients were confirmed to harbor the drug-resistant mutations in serum virions during an NA therapy longer than 6 months. Total DNA was extracted from PBMCs isolated from 30 whole blood samples at the same time point as that of serum analysis. Plasmid-safe ATP-dependent DNase (PSAD digestion in combination with rolling circle amplification and gap-spanning semi-nested PCR were used to amplify the RT region of HBV cccDNA. NA-resistant-associated mutations were analyzed at nine sites. Results  HBV cccDNA was efficiently amplified in 16 out of 30 (53.3% PBMC samples, and the detection rate was not correlated with HBeAg-positive rate, serum ALT level or HBV DNA load. Five of 16 (31.3% patients were sustained to have genotype B HBV infection, and 11 of 16 (68.8% were of genotype C HBV infection, and the result was consistent with the genotyping results using serum HBV. Different from drug-resistant mutations detected in the serum virions, the viruses detected in HBV cccDNA of 16 PBMC samples were all wild-type viruses without NA-resistant-associated mutations in RT region. Conclusions  During NA antiviral treatment, if drug-resistant mutations occur in serum HBV DNA of CHB patients, the dominant species of HBV cccDNA in PBMCs from the same patient is still the original wild-type strains. It is speculated that PBMCs might be the potential "repository" of HBV wild-type strain in vivo.

  11. Determination of oligo elements, platinum and relation Zn/Cu in samples of blood serum and urine among oncological pediatric patients by means of Total Re flexion X-Ray Fluorescence

    International Nuclear Information System (INIS)

    Full text: An analytic methodology has been developed by means of Total Reflection X-Ray Fluorescence, for the determination of oligo elements, platinum in serum and urine, and the relation Zn/Cu in samples of blood serum of oncological pediatric patient. The technique allows the simultaneous determination of interesting elements with quantities of samples of microliters order, which is an advantage over other atomic spectroscopy techniques, because the analytic quality of the results is comparable. A simple procedure was developed by TXRF that allows the monitoring of levels of platinum in serum and urine, of drugs containing platinum, administered to patients under chemotherapy treatment, at the same time that the levels of Ca, K and the oligo elements Zn, Cu, Fe and Se are obtained. The procedure was also applied to the analysis of oligo elements in samples of serum and urine among oncological pediatric patient before the treatment and in a normal group (healthy) as reference. From the results obtained, it is deduced that there are significant differences among the total average levels of Zn and Cu among the groups with cancer and normal, as well as in the relation Zn/Cu, which was shown like a parameter with possible capacity for the cancer diagnosis in a more appropriated way than the oligo elements level, as it has already been reported before in the literature of researches on cancer in adults. All the details inherent to the developed analytic method will be object of discussion

    AIM: Noninvasive diagnosis of hepatic fibrosis has become the focus because of the limited biopsy, especially in the surveillance of treatment and in screening hepatic fibrosis.Recently, regulatory elements involved in liver fibrosis, such as platelet derived growth factor-BB (PDGF-BB), transforming growth factor-β1 (TGF-β1), matrix metalloproteinase-1 (MMP-1), and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1), have been studied extensively. To determine whether these factors or enzymes could be used as the indices for the diagnosis of hepatic fibrosis, we investigated them by means of receiver operating characteristic (ROC) curve.METHODS: Serum samples from sixty patients with chronic viral hepatitis B and twenty healthy blood donors were assayed to determine the level of PDGF-BB, TGF-β1, MMP-1, and TIMP-1 with ELISA, and HA, PCIII, C-IV, and LN level with RIA. The message RNA (mRNA) expression of TIMP-1 and MMP-1 in peripheral blood mononuclear cells (PBMCs) was detected by RT-PCR and Northern blot hybridization. Liver biopsy was performed in all patients.The biopsy samples were histopathologically examined. The trial was double-blind controlled.RESULTS: The serum level of PDGF-BB, TIMP-1, the ratio of TIMP-1 and MMP-1 (TIMP-1/MMP-1), mRNA expression of TIMP-1 (TIMP-1mRNA), and the ratio of TIMP-1mRNA and MMP-1mRNA (TIMP-1mRNA/MMP-1mRNA) in patients was significantly higher than those in the healthy blood donors (t=2.514-11.435, P=0.000-0.016). The serum level of PDGF-BB, TIMP-1, TIMP-1/MMP-1, and TIMP-1mRNA was positively correlated with fibrosis stage and inflammation grade (r=0.239-0.565, P=0.000-0.033), while the serum level of MMP-1 was negatively correlated with fibrosis stage and inflammation grade, and TIMP-1mRNA/MMP-1mRNA was positively correlated with inflammation grade. Through the analysis by ROC curve, serum PDGF-BB was the most valuable marker, and its sensitivity was the highest among the nine indices. The markers with the highest

    β-alanine (BA) supplementation may increase muscle buffering capacity and affect physiological responses during exercise. We examined the effects of 4 weeks of BA supplementation on muscle carnosine and serum lactate in male rats. Rats (n = 24, age: 2 months, body weight: 265±22 g) were divided into a BA supplementation or control group. Along with aerobic acclimatization exercise (15 m·min(-1), 8-10 min·day(-1), 4 days·week(-1) for 4 weeks), the BA group had access to BA powder in their drinking water (1.8%) with the control group having access to plain water for 4 weeks. After 4 weeks, rats ran on a treadmill at speeds of 15, 20, 25, 30, and 35 m·min(-1), respectively, each for 4 min, in order to measure post-exercise serum lactate. Muscle carnosine and serum lactate levels were measured with high-performance liquid chromatography (HPLC) and enzyme-linked immunosorbant assay (ELISA) procedures, respectively. Following BA supplementation, carnosine content in the m.rectus femoris increased by 117% (p carnosine content and reduces serum lactate; these changes may indicate an adaptation of rat skeletal muscles to postpone peripheral muscle fatigue during high-intensity exercise.

    The aim of this paper is to investigate the content of chromium, cobalt and nickel in serum and erythrocytes in children with type 1 diabetes mellitus, depending on the level of glycemic control. The study was conducted on 68 children with type 1 diabetes mellitus. The patients were divided into four groups based on glycemic control. Group I was composed of 9 children with optimal level of glycemic control. Group II - 25 children with suboptimal level of glycemic control. Group III - 34 children with a high risk to life level of glycemic control. Group IV (control group) consisted of 30 healthy children. Compensation state of type 1 diabetes was evaluated according to ISPAD (Consensus for the Management of Type 1 Diabetes Mellitus in Children and Adolescens 2000). The content of trace elements in biological agents was determined by atomic absorbtion spectrophotometry method with C-115M1 mass-spectrophotometer, manufactured by «Selmi» enterprise (Ukraine). It is found that there is a decrease in serum concentrations of chromium and erythrocyte content of cobalt in patients with optimal level of glycemic control. The deficiency of chromium is accompanied by the deficiency of cobalt in patients with suboptimal level of glycemic control. The lower levels of cobalt and nickel are recorded simultaneously, but there is theexcess of chromium in the erythrocytes of these patients. Patients, who suffer from 1 type diabetes mellitus and high risk for life level of glycemic control have considerable polideficiency of cobalt, nickel and chromium in serum.The increasing level of chromium was recorded only in the erythrocytes. The level of glycemic control and the duration of 1 type diabetes mellitus are important in the forecasting of the development of chronic diabetic complications. It is found that the duration of 1 type diabetes mellitus influences the levels of cobalt and nickel in serum mostly, while the level of glycemic control influences the chromium content. PMID

    Arsenic (As) exerts oxidative stress with depletion of body selenium in monogastric animals. But in ruminants this fact is not yet verified. Vitamin E is an effective dietary antioxidant. Thus, in this experiment, the protective effect of vitamin E against arsenic toxicity induced by sodium arsenite (60mg As/kg diet) was investigated in goat kids. For this, 21 male kids were divided into three equal groups and fed either basal diet as such (control), or supplemented with 60mg As/kg diet and 60mg As/kg diet+250IU vitamin E/kg diet for 180 days. Vitamin E supplementation alleviated the toxic effects caused by arsenic on serum alanine aminotransferase and aspartate aminotransferase and lipid peroxidation. It also prevented the depletion of reduced glutathione content and reduction in activity of catalase, superoxide dismutase and glutathione-s-transferase in erythrocytes resulted from arsenic intoxication. The elevated levels of arsenic and reduced levels of selenium in the serum and tissues in arsenic treated animals were attenuated by vitamin E supplementation, though not completely. However, serum cortisol level was not affected by arsenic. It was concluded that arsenic exerts cortisol independent stressor mechanism and supplementation of vitamin E at a level of 250IU/kg diet was partially effective in reducing tissue accumulation of arsenic in the body and protect the kids from oxidative stress induced by arsenic.

  2. Diagnostic informative value of gastroduodenal regulatory peptides of the blood serum on an empty stomach and after test breakfasts of various compositions

    International Nuclear Information System (INIS)

    Gastrin, secretin and cholecystokinin were determined by a radioimmunoassay in healthy persons (19) and in patients with peptic ulcer (13) on an empty stomach and after test breakfasts with different nutrients. In the healthy persons the blood concentration of regulatory peptides was lower than in the patients. Breakfasts increased the concentrations of gastrin, secretin and cholecystokinin in the patients much more than in the controls. Some differences in changes of the blood concentration of peptides were noted with regard to a type of test breakfast. However differentiated reactions of the endocrine apparatus of the gastroduodenal complex in response to the breakfasts were not a reliable functional and diagnostic criterion

    In a study made in the follow-up clinic on 684 patients with mammary carcinoma it was found that there were 64 cases of local recurrence and 244 cases of distant metastases. In both groups the serum iron and the serum copper balance in blood tests, in relation to the clinical proof of local recurrence and/or distant metastases, was investigated. It was found that there were 43.7% pathological serum iron and serum copper findings with local recurrences and 62.7% with distant metastases. The drift apart tendency of the blood serum values in patients with distant metastases could be proved in 78.7% of the cases and in 77.5% of the cases before any clinical proof. Thus, these observations allow the statement that the blood serum iron and serum copper imbalance in blood tests is of very real value in the early diagnosis of distant metastases.

    Cytokines are essential mediators of immune response and inflammatory reactions. Patients with chronic renal failure (CRF) commonly present with abnormalities of immune function related with impaired kidney function and the accumulation of uremic toxins in addition to bioincompatibility of dialyzer membranes. During a hemodialysis (HD) session, cytokines are released mainly by monocytes activated by endotoxin-type compounds in dialyzer fluid,complement factors and direct contact with dialyzer membrane. The study included 15 CRF patients, aged 36.4 ± 2.9 years, on regular HD maintenance therapy for mean 68 ± 10 months and 15 healthy controls. It was designed to assess serum levels of a panel of inflammatory cytokines: IL-1β, IL-2, IL-6, IL-8 and TNF-α in CRF patients on regular maintenance HD before, 20, 60 and 240 minutes of a single HD session in parallel with C-reactive protein (CRP) as an additional parameter. CRP concentration was increased in HD patients when compared with healthy controls. The concentrations of IL-1, IL-6, IL-8 and TNF-α were increased, whereas the serum level of IL-2 was not altered during a single HD session.

  6. The bone mass density in men aged over 50 and its relation to the concentration of free and total testosterone in the blood serum

    International Nuclear Information System (INIS)

    As the mean length of life increases, osteoporosis affects a growing number of men and women, thus becoming an important medical and socioeconomic problem in many countries. Pathogenesis and the prevalence of the osteoporosis in women are well established, however, in men, they are still controversial. In this study, the bone mass density (BMD) of the lumbar spine was determined in 100 healthy men age 50-83, using quantitative computed tomography (QCT). Also, the total serum and free testosterone was measured. The mean BMD was 123.1I39.3 mg/cm3, and the values below a fracture threshold were noted in 39% of subjects. The mean concentration of total and free serum testosterone was 4.3I1.7 ng/ml and 6.2I3.7 pg/ml, respectively. There was a significant (p3, respectively). There was no correlation found between total testosterone and BMD. Results indicate that reduced bone mass density in males over 50 is as frequent as recently reported in females. Moreover, sex hormones seem to be related to osteoporosis development in men as well. (author)

    In the blood sera of pigs vaccinated with inactivated vaccines manufactured by three different manufacturers the RIA method was used to determine the specific antibodies to the virus of Aujeszky's disease. In certain groups of vaccinated pigs the results of the RIA examination are unfavourably affected by the bond of antibodies to the cellular antigenous determinants. This proves that following vaccination antibodies are formed not only against the viral antigen but also against the antigens of cells on which the vaccination virus is propagated. These shortcomings are eliminated by the use of suitable cellular cultures for the preparation of viral and control antigens. Antigens are applicable for RIA and for ELISA examinations of blood sera of infected and vaccinated pigs. The advantages are described of the RIA and ELISA methods as compared with the virus neutralization test.

    利用fat-1转基因小鼠模型,研究内源性n-3多不饱和脂肪酸(n-3 PUFAs)的血糖血脂调节作用.采用fat-1转基因小鼠和C57BL/6野生型小鼠喂食高n-6、低n-3 PUFAs的标准配方饲料4周,然后2组小鼠给予高糖饮液自由饮用4周,每周测体重.第8周末,取血离心测血糖、胰岛素、甘油三脂(TG)、胆固醇(TC)、高密度脂蛋白(HDL-C)、低密度脂蛋白(LDL-C)水平.结果表明:fat-1转基因小鼠体重增加幅度、空腹血糖值、血清胰岛素、胰岛素抵抗指数、血清TC、TG、HDL-C、LDL-C水平明显低于野生型小鼠(P<0.05).认为n-3 PUFAs能抑制体重增长,降低小鼠血糖、血脂和胰岛素抵抗,起到调节血糖、血脂的作用.%In this study, we investigate the effects of endogenous n-3 PUFAs on blood glucose and serum lipid in fat-1 transgenic mouse model. The transgenic and wild type mice are maintained on a 10%corn oil diet which has high ratio of n-6/n-3 polyunsaturated fatty acids for 4 weeks. Then make them drink high sugar pinocytosis freely for another four weeks. On the eighth weekend, serum glucose, insulin, serum triglyceride (TG), serum total cholesterol (TC), serum high-density lipoprotein cholesterol (HDL-C), serum low-density lipoprotein cholesterol (LDL-C) levels of blood serum are tested after blood collection and centrifugation. The weight gain rate, fasting blood sugar and serum insulin levels, insulin resistance index, serum TC, TG, HDL-C, LDL-C of fat-1 transgenic mice are found to be significantly lower than those of wild type mice (P<0.05). The tests indicate that n-3 polyunsaturated fatty acids can reduce the blood glucose and serum lipid, which may play a vital role in regulating blood lipid and decreasing insulin resistance.

    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-I-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. PMID:9254521

    Iron, copper, zinc and selenium were determined directly in serum samples from healthy individuals ( n=33) and cancer patients ( n=27) by total reflection X-ray fluorescence spectrometry using the Compton peak as internal standard [L.M. Marcó P. et al., Spectrochim. Acta Part B 54 (1999) 1469-1480]. The standardized concentrations of these elements were used as input data for two-layer artificial neural networks trained with the generalized delta rule in order to classify such individuals according to their health status. Various artificial neural networks, comprising a linear function in the input layer, a hyperbolic tangent function in the hidden layer and a sigmoid function in the output layer, were evaluated for such a purpose. Of the networks studied, the (4:4:1) gave the highest estimation (98%) and prediction rates (94%). The latter demonstrates the potential of the total reflection X-ray fluorescence spectrometry/artificial neural network approach in clinical chemistry.

    High-dose chemotherapy with autologous bone marrow and/or peripheral blood stem cell (PBSC) support is increasingly employed in the adjuvant treatment of high-risk breast cancer. Subsequent radiotherapy has been reported to be associated with morbidity and mortality resulting from pulmonary toxicity. In addition, the course of radiation therapy may be hampered by excess myelosuppression. The aim of this study was to investigate the contribution to radiation-induced toxicity of a high-dose chemotherapy regimen (CTC) that incorporates cyclophosphamide, thiotepa and carboplatin, in patients with high-risk breast cancer.

    The administration of angiotensin II receptor antagonist(AIIA) to patients with advanced chronic renal failure(CRF) is not actively recommended. This study was performed to verify the appropriateness of this situation and to determine if there are any substantial differences between patients with a serum creatinine(SCr) level higher than 3 mg/dl and those with a lower SCr level in terms of the clinical effects such as renal function, serum potassium level and systemic blood pressure(BP) after the administration of AIIA. Sixteen patients with advanced CRF who were admitted to the out-patient clinic in Jikei University Hospital(1998/1-1999/12) were enrolled(average age: 65 years, underlying renal disease: diabetic nephropathy 6, CGN 5, and other 1). They had never been administered AIIA before. The patients were classified into two groups in accordance with their level of SCr: group A(SCr lower than 3.0 mg/dl; n = 11), and Group B(SCr higher than 3.0 mg/dl; n = 5). Losartan(50 mg/day) administration was started in order to examine parameters such as the SCr, potassium, BP at the out-patient clinic, and urinary protein excretion at the 0, 1, 3, 6, 9, and 12 month time points. Although the 1/SCr values provided negative slopes with time in both groups, no significant difference was found between the two slopes. There were no changes in the serum potassium levels or urinary protein excretion during the study period in either group, and no statistical difference was found between the two groups. Although the serum potassium level exceeded 5.5 mEq/l in two patients each in both groups, the level was controlled by diet therapy with restricted potassium. BP was reduced significantly in both groups during the study period, and no statistical difference in BP reduction was observed between the two groups. In conclusion, the results indicate there were no differences in the effect on renal function, serum potassium levels or systemic BP between the patients with a SCr level

    A simple, cost effective, and fast gas chromatography method with flame ionization detection (GC-FID) for simultaneous measurement of ethylene glycol, 1,2-propylene glycol and glycolic acid was developed and validated for clinical toxicology purposes. This new method employs a relatively less used class of derivatization agents - alkyl chloroformates, allowing the efficient and rapid derivatization of carboxylic acids within seconds while glycols are simultaneously derivatized by phenylboronic acid. The entire sample preparation procedure is completed within 10 min. To avoid possible interference from naturally occurring endogenous acids and quantitation errors 3-(4-chlorophenyl) propionic acid was chosen as an internal standard. The significant parameters of the derivatization have been found using chemometric procedures and these parameters were optimized using the face-centered central composite design. The calibration dependence of the method was proved to be quadratic in the range of 50-5000 mg mL(-1), with adequate accuracy (92.4-108.7%) and precision (9.4%). The method was successfully applied to quantify the selected compounds in serum of patients from emergency units.

    The favorable effects of fulvic acids as fertilizers are very well known and they have been used long time ago in their natural state in dead leaves. Their extraction from natural sources is rather expensive, but the production of very similar carbon amino saccharides by sugar oxidation has been industrially applied in Mexico. Good properties of this commercial product as fertilizer have been proved empirically in different crops as well as at laboratory level, by the efficient absorption of radioactive labeled mineral ions in vegetables when they are carried by this synthetic organic matter in aqueous solution. Now, its effect has been tested by filtration of radioactively labeled 45Ca2+ and 32PO 4 3- ions from drinking water to blood serum through mice liver and kidneys. The results indicate that the filtration and diffusion of these mineral ions also improved, the same that in vegetables, in the presence of the synthetic carbon amino saccharides highly soluble in water. These results suggest the appropriateness of further research to evaluate their possible use either as a dietary complement or as auxiliaries in the treatment of liver and kidney diseases.

    A forensic procedure for the quantitative confirmation of lysergic acid diethylamide (LSD) and the qualitative confirmation of its metabolite, N-demethyl-LSD, in blood, serum, plasma, and urine samples is presented. The Zymark RapidTrace was used to perform fully automated solid-phase extractions of all specimen types. After extract evaporation, confirmations were performed using liquid chromatography (LC) followed by positive electrospray ionization (ESI+) mass spectrometry/mass spectrometry (MS/MS) without derivatization. Quantitation of LSD was accomplished using LSD-d3 as an internal standard. The limit of quantitation (LOQ) for LSD was 0.05 ng/mL. The limit of detection (LOD) for both LSD and N-demethyl-LSD was 0.025 ng/mL. The recovery of LSD was greater than 95% at levels of 0.1 ng/mL and 2.0 ng/mL. For LSD at 1.0 ng/mL, the within-run and between-run (different day) relative standard deviation (RSD) was 2.2% and 4.4%, respectively.

  6. Serum ferritin

    International Nuclear Information System (INIS)

    Serum ferritin (SF) concentration as determined by the immunoradiometric method allows the direct measurement of a fraction of the body ferritin pool. In normal subjects, SF is an excellent index of body iron stores. In certain conditions associated with increased ferritin synthesis (such as liver disease, inflammation, malignancy, chronic disorders, ineffective erythropoiesis, or during ferrotherapy), SF may not accurately reflect body iron stores. In hyposideremic anemias SF concentration permits to differentiate those due to iron deficiency from those due to chronic disorders. With a good assay quality, subnormal SF levels are incontrovertible in the diagnosis of iron deficiency. SF determination has been investigated as possible tumor marker. When performed in combination with the alpha-fetoprotein assay, SF enhances the specificity of serodiagnosis of hepatoma. SF results must be interpreted bearing in mind the possible participation of circumstances that i) modify the body iron stores and ii) lead to increased ferritin synthesis. (author)

    methodology with favorable cost/benefice ratio. The use of this methodology implies in reference interval estimation. OBJECTIVE: To estimate the reference interval for serum ionized calcium, and to evaluate interferences in tourniquet time application, and interferences in sample refrigeration before analysis. MATERIAL AND METHOD: to estimate the reference interval we included the results of 11,320 consecutive calcium ionized determinations accomplished from January 2000 to November 2002; in order to evaluate the effect of sample refrigeration, 16 samples were collected in duplicate, so that one tube was placed in ice bath and the other was maintained in room temperature. To evaluate the effect of tourniquet application time, we collected blood samples from one arm of 6 normal subjects, immediately after, and from the other arm, after 3 minutes of the tourniquet application. The blood was collected in evacuated tubes with gel separator and centrifuged up to 30 minutes after collection. All determinations were performed up to 4 hours after the centrifugation by ion-selective electrode. RESULTS: regarding to the central 95% data distribution, the inferior and superior limits were, respectively, 1.11 (confidence interval of 90%: 1.1 to 1.11 and 1.4mmol/l (confidence interval of 90%: 1.39 to 1.41. No significant differences were detected between results with and without refrigeration and between samples with less than 1 and after 3 minutes of tourniquet application.

    Full Text Available "Free" iron, a potentially radical-generating low mass iron, and not found in normal human blood, was increased in the serum of blood-transfused thalassemia major patients seen in the Yangon General Hospital, Yangon, Myanmar (Burma. The low mass iron was detected by the bleomycin assay. Fifty-one blood samples were analyzed (from 28 males and 23 females. High "free" iron was detected in 47 sera samples from thalassemia patients. Serum ferritin, which reflects the body store iron, was higher than the normal range (10-200 ng/ml in 49 patients. On the other hand, serum iron of 39 sera samples fell within the normal range (50-150 micrograms/dl. Four were less than 50 micrograms/dl and eight were more than 150 micrograms/dl. Almost all the patients' sera of normal or higher serum iron level contained "free" iron. Thus, almost all the sera from thalassemic patients from Myanmar contain bleomycin-detectable iron, even when serum iron is within the normal range. In developing countries where undernutrition is prevalent (serum albumin in these patients was 3.6 +/- 0.4 g/dl, P < 0.0001 vs. control value of 4.0 - 4.8 g/dl, normal serum iron does not preclude the presence of free iron in the serum.

However, the relationship between serum calcium and coronary heart disease is unclear. The purpose of this study was to compare serum calcium levels in patients with coronary heart disease and those in healthy individuals. Methods: This retrospective, case-control study conducted in the People's Republic of China comprised 380 cases and 379 controls. Serum calcium levels, blood lipids, and anthropometric measurements were measured in both groups. The Student's unpaired t-test or Chi-square test was used to compare differences between cases and controls. Pearson's partial correlation coefficient was used to determine the association between serum calcium, blood lipids, and blood pressure in both groups. Results: Our results indicate that the average level of serum calcium in cases was higher than in controls. Serum calcium levels showed no correlation with any parameter except for triglycerides in either group. Conclusion: Overall, these data suggest that serum calcium has no influence on coronary heart disease or triglyceride levels in the general population.

    With the increase of people"s living standard and the changes of living form, the number of people who suffer from hypercholesterolemia is increasing. It is not only harmful to heart and blood vessel, but also leading to obstruction of cognition. The conventional blood detection technology has weakness such as complex operation, long detecting period, and bad visibility. In order to develop a new detection method that can checkout hypercholesterolemia conveniently, spectroscopy of cholesterol in hypercholesterolemia serum is obtained by the multifunctional grating spectrograph. The experiment results indicate that, under the excitation of light-emitting diode (LED) with the wavelength at 407 nm, the serum from normal human and the hypercholesterolemia serum emit different fluorescence spectra. The former can emit one fluorescence region with the peak locating at 516 nm while the latter can emit two more regions with peaks locating at 560 nm and 588 nm. Moreover, the fluorescence intensity of serum is non-linear increasing with the concentration of cholesterol increases when the concentration of cholesterol is lower than 13.8 mmol/L, and then, with the concentration of cholesterol increase, the fluorescence intensity decreases. However, the fluorescence intensity is still much higher than that of serum from normal human. Conclusions can be educed from the experiments: the intensity and the shape of fluorescence spectra of hypercholesterolemia serum are different of those of normal serum, from which the cholesterol abnormal in blood can be judged. The consequences in this paper may offer an experimental reference for the diagnosis of the hypercholesterolemia.

  20. Ferritin. Radioimmunological determination in serum and clinical significance

    International Nuclear Information System (INIS)

    Ferritin is an iron storage protein which has been shown to be present in blood serum only recently. An immunoradiometric determination of ferritin in 324 subjects with different iron stores is reported. In healthy men and women a ferritin concentration of 131 μg/l (SD: 1.59) and 67 μg/l (SD: 1.79) was found respectively. In male and female blood donors as well as patients with iron deficiency and iron overload significant differences of serum ferritin concentration could be demonstrated. In clinical practice the determination of serum ferritin is a valuable method for the estimation of body iron stores. (orig.)

    Three groups of male rats were housed in metabolic cages. The control group was fed ad libitum, a second group was fasted and diabetes was induced in the third group by the subcutaneous injection of alloxan. After 48 hours all animals were bled and livers, which were quick-frozen in situ, were obtained. Fasted and diabetic animals were ketotic as manifested by lowering urinary pH and elevated urinary and blood acetoacetate and ..beta..-hydroxybutyrate. Blood and hepatic content of acetate was elevated in diabetic versus control rats. Blood and hepatic content of acetate was not increased in fasted animals. In fasted rats total urinary Zn and Cu were decreased and Mg and Ca did not differ significantly from control values. In diabetic rats total urinary excretion of Mg was increased whereas urinary Zn, Cu and Ca levels did not differ significantly from control values. In fasted animals only serum Zn was diminished. In diabetic rats serum Cu and Ca were decreased and serum Mg was increased while serum Zn was unchanged. Thus, the ketosis of fasting differs from the ketosis of diabetes in several of its metabolic manifestations. 11 references, 9 figures.

    Antimicrobial activity of sera from many crocodilian species has been recognized. This activity was proposed to be mediated, at least in part, by complement. Due to the fact that complement proteins have different functions in the immune system, they may be involved in phagocytic process of phagocytes. In the present study, the effects of Siamese crocodile serum on phagocytic activity of macrophages as well as the possible involvement of complement in this process were examined. The results showed increases in the phagocytosis of both Escherichia coli and to a lesser extent, Staphylococcus aureus upon incubation of murine macrophage cell line with fresh crocodile serum (FS). Similar to FS, other crocodile blood products, including freeze dried serum (DS) and freeze dried whole blood (DWB) exhibited phagocytosis-enhancing property. However the ability of DWB to enhance phagocytosis was less efficient than that of FS and DS, suggesting that serum factors were involved in this process. Treatment of FS with heat at 56 degrees C for 30 min deteriorated the effect of FS on bacterial uptake of macrophages, suggesting that complement proteins play a role in the modulation of the phagocytic process. Collectively, the results of the present study suggested that crocodile serum enhances the macrophage phagocytic activity through complement activity and, therefore, may be taken as an alternative medicine for supporting the human immune responses.

    2008-01-01

    Full Text Available Artificial blood is a product made to act as a substitute for red blood cells. While true blood serves many different functions, artificial blood is designed for the sole purpose of transporting oxygen and carbon dioxide throughout the body. Depending on the type of artificial blood, it can be produced in different ways using synthetic production, chemical isolation, or recombinant biochemical technology. Development of the first blood substitutes dates back to the early 1600s, and the search for the ideal blood substitute continues. Various manufacturers have products in clinical trials; however, no truly safe and effective artificial blood product is currently marketed. It is anticipated that when an artificial blood product is available, it will have annual sales of over $7.6 billion in the United States alone.

    The authors present the results of using the indirect hemagglutination inhibition test (IHIT) for quantitative determination of A, M and G immunoglobulins in the blood sera of humans in comparison with the method of radial immunodiffusion in agar (RID) after Mancini. The results of IHIT were no less precise and reproducible than those of RID. The significance of the correlation coefficient of grades after Spirman constituted greater than 99.9% for both tests. On this basis a conclusion was made that, having a number of advantages over RID, IHIT could be recommended for quantitative titration of immunoglobulins of various classes. PMID:804778

    Full Text Available Background and aims: Dysphagic patients who underwent endoscopic gastrostomy (PEG usually present protein-energy malnutrition, but little is known about micronutrient malnutrition. The aim of the present study was the evaluation of serum zinc in patients who underwent endoscopic gastrostomy and its relationship with serum proteins, whole blood zinc, and the nature of underlying disorder. Methods: From patients that underwent gastrostomy a blood sample was obtained minutes before the procedure. Serum and whole blood zinc was evaluated using Wavelength Dispersive X-ray Fluorescence Spectroscopy. Serum albumin and transferrin were evaluated. Patients were studied as a whole and divided into two groups: head and neck cancer (HNC and neurological dysphagia (ND. Results: The study involved 32 patients (22 males, aged 43-88 years: HNC = 15, ND = 17. Most (30/32 had low serum zinc, 17/32 presented normal values of whole blood zinc. Only two, with traumatic brain injury, presented normal serum zinc. Serum zinc levels showed no differences between HNC and ND patients. There was no association between serum zinc and serum albumin or transferrin. There was no association between serum and whole blood zinc. Conclusions: Patients had low serum zinc when gastrostomy was performed, similar in HNC and ND, being related with prolonged fasting and unrelated with the underlying disease. Decrease serum zinc was unrelated with low serum proteins. Serum zinc was more sensitive than whole blood zinc for identifying reduced zinc intake. Teams taking care of PEG-patients should include zinc evaluation as part of the nutritional assessment, or include systematic dietary zinc supply.

    Obesity, metabolic syndrome, dyslipidemia, and poor quality of life are common conditions associated with hypertension, and incidence of hypertension is age dependent. However, an effective program to prevent hypertension and to improve biomedical factors and quality of life has not been adequately examined or evaluated in Chinese older adults. This study aims to examine the effectiveness of a Tai Chi program to improve health status in participants with hypertension and its related risk factors such as dyslipidemia, hyperglycemia, and quality of life in older adults in China. A randomized study design was used. At the conclusion of the intervention, 266 patients remained in the study. Blood pressure and biomedical factors were measured according to the World Diabetes Association standard 2002. A standardized quality-of-life measure was used to measure health-related quality of life. It was found that a Tai Chi program to improve hypertension in older adults is effective in reducing blood pressure and body mass index, maintaining normal renal function, and improving physical health of health-related quality of life. It did not improve existing metabolic syndrome levels, lipid level (dyslipidemia) or fasting glucose level (hyperglycemia), to prevent further deterioration of the biomedical risk factors. In conclusion, Tai Chi is effective in managing a number of risk factors associated with hypertension in Chinese older adults. Future research should examine a combination of Tai Chi and nutritional intervention to further reduce the level of biomedical risks.

  9. Assessment of Serum Vitamin D Levels in Hypertensive Patients

    International Nuclear Information System (INIS)

    High blood pressure is very prevalent worldwide, as well as vitamin D deficiency. There are several observation data that support the concept that vitamin D is involved in the pathogenesis of hypertension. Also some clinical data demonstrate positive effect of vitamin D therapy on hypertension. We studied serum levels of vitamin D and its association with blood pressure in 30 hypertensive patients and 20 age and socioeconomic status matched healthy controls. There was no statistically significant difference in serum vitamin D levels in the group of patients compared with controls. In patients group, patients with body mass index (BMI) > 30 kg/m2 showed statistically significant decrease in serum vitamin D levels as compared to those with BMI ≤ 30 kg/m2 (P = 0.021). There was no significant association between serum vitamin D levels and age, systolic and diastolic blood pressure in the group of patients. A negative correlation between serum vitamin D levels and BMI was found in patients group (P = 0.045). In conclusion, no association between serum levels of vitamin D and blood pressure in hypertensive patients, but it is statistically associated with BMI. Further large scale studies are needed putting in consideration the effect of genetic factor

    Full Text Available The interest in the clinical importance of serum magnesium level has just recently begun with the analysis and findings of abnormal magnesium level in cardiovascular, metabolic and neuromuscular disorder. Although the serum level does not reflect the body magnesium level, but currently, only serum magnesium determination is widely used. Erythrocyte magnesium is considered more sensitive than serum magnesium as it reflects intracellular magnesium status. According to NCCLS (National Committee for Clinical Laboratory Standards every laboratory is recommended to have its own reference range for the tests it performs, including magnesium determination. The reference range obtained is appropriate for the population and affected by the method and technique. This study aimed to find the reference range of serum and plasma magnesium and also intracellular magnesium i.e. erythrocyte magnesium by direct method, and compare the results of serum and plasma magnesium. Blood was taken from 114-blood donor from Unit Transfusi Darah Daerah (UTDD Budhyarto Palang Merah Indonesia (PMI DKI Jakarta, consisted of 57 male and 57 female, aged 17 – 65 years, clinically healthy according to PMI donor criteria. Blood was taken from blood set, collected into 4 ml vacuum tube without anticoagulant for serum magnesium determination and 3 ml vacuum tube with lithium heparin for determination of erythrocyte and plasma magnesium Determination of magnesium level was performed with clinical chemistry auto analyzer Hitachi 912 by Xylidil Blue method colorimetrically. This study showed no significant difference between serum and heparinized plasma extra cellular magnesium. The reference range for serum or plasma magnesium was 1.30 – 2.00 mEq/L and for erythrocyte magnesium was 4.46 - 7.10 mEq/L.

    Full Text Available   Stem cells are naïve or master cells. This means they can transform into special 200 cell types as needed by body, and each of these cells has just one function. Stem cells are found in many parts of the human body, although some sources have richer concentrations than others. Some excellent sources of stem cells, such as bone marrow, peripheral blood, cord blood, other tissue stem cells and human embryos, which last one are controversial and their use can be illegal in some countries. Cord blood is a sample of blood taken from a newborn baby's umbilical cord. It is a rich source of stem cells, umbilical cord blood and tissue are collected from material that normally has no use following a child’s birth. Umbilical cord blood and tissue cells are rich sources of stem cells, which have been used in the treatment of over 80 diseases including leukemia, lymphoma and anemia as bone marrow stem cell potency.  The most common disease category has been leukemia. The next largest group is inherited diseases. Patients with lymphoma, myelodysplasia and severe aplastic anemia have also been successfully transplanted with cord blood. Cord blood is obtained by syringing out the placenta through the umbilical cord at the time of childbirth, after the cord has been detached from the newborn. Collecting stem cells from umbilical blood and tissue is ethical, pain-free, safe and simple. When they are needed to treat your child later in life, there will be no rejection or incompatibility issues, as the procedure will be using their own cells. In contrast, stem cells from donors do have these potential problems. By consider about cord blood potency, cord blood banks (familial or public were established. In IRAN, four cord blood banks has activity, Shariati BMT center cord blood bank, Royan familial cord blood banks, Royan public cord blood banks and Iranian Blood Transfusion Organ cord blood banks. Despite 50,000 sample which storage in these banks, but the

    study of the historical rise and current workings of safety practices in the Danish blood system. Here, we identify a strong focus on contamination in order to avoid 'tainted blood', at the expense of working with risks that could be avoided through enhanced blood monitoring practices. Of further...... significance to this focus are the social dynamics found at the heart of safety practices aimed at avoiding contamination. We argue that such dynamics need more attention, in order to achieve good health outcomes in transfusion medicine. Thus, we conclude that, to ensure continuously safe blood systems, we...... need to move beyond the bifurcation of the social and medical aspects of blood supply as two separate issues and approach social dynamics as key medical safety questions....

  6. Ferritin in cattle serum

    International Nuclear Information System (INIS)

    A commercially available radioimmunoassay kit for human serum ferritin was used to determine the ferritin concentration in serum or plasma of 41 calves from 0 to 106 days of age, 192 cows and 35 bulls from 2 to 11 years of age. The geometric average concentration of ferritin was 2.1, 12.6 and 4.5 ng/ml for the calves, cows and bulls, respectively. The cows were statistically different from the calves and bulls; there were no differences between the calves and bulls. Within the cows one herd was found to have lower serum ferritin levels than all the other herds (P < 0.05) but no differences in packed cell volumes were present. The data suggest that a radioimmunoassay procedure with a ferritin antibody specific for bovine ferritin could be useful in the study of iron metabolism in cattle. (author)

    Objective The low rate of engraftment in children with β-thalassemla has seriouslyrestricted the popularity of the hematopoietic stem cell transplantation (HSCT). Panel reactive antibody(PRA) has been regarded as one of the important factors for the success of kidney transplantation. Poly-transfusion before transplantation is associated with the production of PRA. Also PRA is produced in thechildren with β-thalassemia major who need poly-transfusion for life. PRA might be one of factors inducingthe low rate of engraftment in children with β-thalassemia. This study focused on observing the effect of PRAon the proliferation, differentiation, apoptosis and necrosis of cord blood CD34+ cells in vitro by incubatingthe cord blood CD34+ cells with serum containing PRA. Method Seven samples of cord blood werecollected and the HLA typing for every sample was done. Seven sera positive for PRA and seven negativesera were selected respectively. Mononuclear cells ( MNCs ) were obtained by FicoU-Hapaque densitygradient centrifugation. CD34+ cells were isolated from MNCs by positive selection using an immunomagneticseparation ( CD34+ progenitor cell isolation kit and auto-MACS). The CD34+ ceils of umbilical cord bloodwere incubated with the serum and complement in the following groups: A (absence of serum), B (presenceof PRA positive serum ), C (presence of PRA positive serum and complement ), D (presence ofcomplement), and E ( presence of PRA negative serum). After incubation the samples were centrifuged andthe supernatant was collected for LDH detection. At the same time the CD34+ cells were harvested forassessing the expression of Annexin V and CD95 of the CD34+ cells by flow cytometry and also for thedetection of the DNA synthesis by3H-TaR incorporation. Meanwhile the cells were inoculated into themethylcellulose cultural system. The proliferation and hematopoietic potential of the CD34 + cell of cord bloodby the colony formation assay were detected on the day 10. Result

During airway inflammation, many cytokines and chemokines are released and some are detectable in the sera.Objective: Serum chemokines and cytokines, involved in airway inflammation in asthma patients, were investigated.Methods: A total of 191 asthma patients were classified by hierarchical cluster analysis, including the following parameters: forced expiratory volume in 1 second (FEV1, eosinophil cationic protein (ECP serum levels, blood eosinophils, Junipers asthma symptom score, and the change in FEV1, ECP serum levels, and blood eosinophils after 3 weeks of asthma therapy. Serum proteins were measured by multiplex analysis. Receiver operating characteristic (ROC curves were used to evaluate the validity of serum proteins for discriminating between asthma clusters.Results: Classification of asthma patients identified one cluster with high ECP serum levels, increased blood eosinophils, low FEV1 values, and good FEV1 improvement in response to asthma therapy (n=60 and one cluster with low ECP serum levels, low numbers of blood eosinophils, higher FEV1 values, and no FEV1 improvement in response to asthma therapy (n=131. Serum interleukin (IL-8, eotaxin, vascular endothelial growth factor (VEGF, cutaneous T-cell-attracting chemokine (CTACK, growth-related oncogene (GRO-α, and hepatocyte growth factor (HGF were significantly different between the two clusters of asthma patients. ROC analysis for serum proteins calculated a sensitivity of 55.9% and specificity of 75.8% for discriminating between them.Conclusion: Serum cytokine and chemokine levels might be

    to control grass insect pests in the dairy regions of Antioquia, Colombia, has been linkedto thyroid hormone and estradiol alterations. This study used gaschromatography to detect chlorpyrifos residues in the milk and blood of Holstein cows, fed with chlorpyrifos treated grass. Additionally, it measured, by radioimmunoanalysis, the blood levels of thyroid hormone and estradiol in the cows the day before their entrance in the treated pastures and through-out the following 30 days. Although gas chromatography was effective in detecting chlorpyrifos in milk and serum during standardization, it did not detect any chlorpyrifos residues in the serum and milk samples from the studied animals.No significant difference was found in thyroid hormone and estradiol levels through-out the treatment. These findings indicate that treating grass with chlorpyrifos according to manufacturer’s instructions does not generate detectable residues of the insecticide in the blood and milk of the cows feeding on the grass. The results could also indicate that under the manufacturer’s recommendations, chlorpyrifos is not and endocrine disruptor for dairy cows.

    Objective. Adropin is a newly identified regulatory protein encoded by the Enho gene and is critically involved in energy homeostasis and insulin sensitivity. This study aims to determine the correlation of serum adropin concentrations with diabetic nephropathy (DN). Methods. This study consisted of 245 patients with type 2 diabetes mellitus (T2DM) and 81 healthy subjects. Then T2DM patients were divided into normoalbuminuria, microalbuminuria, and macroalbuminuria subgroups based on urine albumin to creatinine ratio (ACR). Results. T2DM patients showed significantly lower serum adropin concentrations than those in the controls. T2DM patients with macroalbuminuria had significantly decreased serum adropin concentrations compared with the other three groups. In addition, T2DM patients with microalbuminuria showed lower serum adropin concentrations than those in patients with normoalbuminuria. Logistic regression analysis showed that serum adropin was correlated with decreased risk of developing T2DM and DN. Pearson correlation analysis indicated that serum adropin was negatively correlated with body mass index (BMI), blood urea nitrogen, creatinine, and ACR and positively correlated with glomerular filtration rate. Furthermore, multiple linear regression analysis showed that BMI and ACR were negatively correlated with serum adropin levels. Conclusion. Serum adropin concentrations are negatively associated with renal function. Adropin may be implicated in the pathogenesis of DN development. PMID:27546995

    A nested, matched case-control study was conducted to assess the relationship between serum levels of copper and the subsequent risk of cancer. One hundred thirty-three cases of cancer were identified during 1974-1984 among 5000 members of a northwest Washington State employee cohort from whom serum specimens had been previously obtained and stored. Two hundred forty-one controls were selected at random from the cohort and were matched to the cases on the basis of age, sex, race, and date of blood draw. Serum copper levels were measured by atomic absorption spectrometry. Risk of a subsequent diagnosis of cancer was positively associated with serum copper levels, but only among those cases diagnosed within 4 years of the time the serum specimens were collected. Among cases diagnosed more than 4 years after specimen collection, there was no consistent association between serum copper levels and risk. Adjustment for age, sex, race, occupational status, cigarette smoking, family history of cancer, alcohol consumption, and, among females, use of exogenous hormones had no appreciable effect on these relationships. The findings suggest that the presence of cancer may increase serum copper levels several years prior to its diagnosis. They are less supportive of the hypothesis that serum copper levels affect cancer risk.

    Full Text Available Objective: The study aims to investigate the risk of post-transfusion transmission of hepatitis c virus (HCV in the circumstances of occult HCV when anti-HCV is undetectable by ELISA and HCV-RNA is detected by RT-PCR in the plasma and or in peripheral blood mononuclear cells (PBMCs of donor blood and the recipients are immunocompromised. Patients & methods: The study covered 18 chronic renal failure patients (CRF [12 males (66.7% their age ranged from 28 to 65 years and 6 females (33.3 % their age ranged from 15 to 55 years] undergoing hemodialysis in Nile Hospital as part of their therapy have to receive blood transfusions (275 blood units for the first time. Commercial ELISA kits for anti-HCV and nested-RT-PCR (N-RT-PCR kits were used. Results: Anti-HCV was positive in one serum from the eighteen (5.5% poly transfused CRF patients at the end of the study while the seventeen sera were negative. This serum was also positive for HCV RNA by N-RT-PCR. Out of the 20 transfused blood units, one blood unit (three components were tested by blood banking anti-HCV negative by ELISA, were positive for HCV RNA by N-RT-PCR. The collective markers of this blood unit represent an occult HCV. The risk of acquiring post-transfusion HCV infection from an occult HCV blood unit is 5%. Real time PCR showed variation in the viral load of the serum of the infected CRF patient, the plasma of blood unit, the PBMCs of this blood unit whether activated by PHA-M or not.

    Cadmium (Cd) is an industrial pollutant and carcinogenic metal. Most in vitro Cd toxicity studies have been carried out in various cell lines cultured in 10% fetal bovine serum (FBS) containing medium. In this report, we compared the toxic effect of Cd (0-300 microM) on cell growth, total RNA, total proteins, and antioxidant enzymes in rat normal liver cells cultured in medium with 10% FBS or commercially available serum-free medium for 4 or 8 hours. With Cd concentration at above 100 microM, the total levels of RNA, protein and cell growth decreased in serum-containing medium, while their levels increased in serum-free medium compared to the controls. The glutathione peroxidase and glutathione reductase levels were lower in serum-free medium than in serum-containing medium, indicating less oxidative stress in cells grown in serum-free medium. These results clearly suggest that Cd showed higher toxicity to liver cells grown in serum-containing medium in comparison to commercially available serum-free medium. It is speculated that albumin and other substances present in commercial serum-free medium chelated Cd and thereby protected these cells against Cd toxicity. Even under in vivo conditions, cadmium enters into various organs after passing through blood which contains serum. Based on these studies, it appears that media containing serum may be ideal for in vivo toxicity correlation studies with animal cells.

    The models of hyperlipidemia tilapia induced by high-fat diet were established to explore the effects of fermented mulberry leaves on serum lipid and blood glucose levels of hyperlipidemia tilapia ( Oreochromis niloticus) . A total of 450 male GIFT tilapia with the initial average body weight of 45 g were randomly divided into 5 groups with 3 replicates per group, and 30 fish in each replicate. The fish in normal control group were fed with a basal diet, and the other 4 groups were fed the basal diet ( model control group) and diets contained 7.5% and 15.0% fermented mulberry leaves ( low level fermented mulberry leaves group and high level fer-mented mulberry leaves group, respectively) , and 0.5% ginkgo flavone ( ginkgo flavone group) after the es-tablishment of the hyperlipidemia model, respectively. The experiment lasted for 8 weeks. The results showed as follows: after feeding 5 and 8 weeks, the body weight in model control group was significantly lower than that in normal control group, low level fermented mulberry leaves group, high level fermented mulberry leaves group and ginkgo flavone group (P0.05) . The serum total cholesterol ( TCHO) and low-density lipoprotein cholesterol ( LDL-C) contents and TCHO/high-density lipoprotein cholesterol ( HDL-C) in low level fermented mulberry leaves group, high level fermented mulberry leaves group and ginkgo fla-vone group were significantly lower than those in model control group (P0.05) . Compared with the model control group, the serum HDL-C content in high level fermented mulberry leaves group and ginkgo flavone group was significantly increased (P0.05). High-fat diet could significantly increase the blood glucose level in model control group, low level fermented mulberry leaves group, high level fermented mulberry leaves group and ginkgo flavone group (0 week, P0.05). These results indicate that fermented mulberry leaves can decrease the serum lipid and blood glucose levels, and enhance the antioxidant ability of

    Normal human serum inhibits Acanthamoeba (encephalitis isolate) binding to and cytotoxicity of human brain microvascular endothelial cells, which constitute the blood-brain barrier. Zymographic assays revealed that serum inhibits extracellular protease activities of acanthamoebae. But it is most likely that inhibition of specific properties of acanthamoebae is a consequence of the initial amoebicidal-amoebistatic effects induced by serum. For example, serum exhibited amoebicidal effects; i.e....

    Full Text Available A 43-year-old man was referred by his general practitioner to the hepatology clinic with deranged serum aminotransferases, discovered as part of routine blood tests. The objective was to identify the cause of elevated serum aminotransferases in this patient in a systematic manner. Thorough history and physical examination revealed a background history of rippling muscle disease secondary to caveolin-3 protein deficiency, with typical clinical signs. There was a positive family history of musculoskeletal disease in the patient's father and brother. Previous diagnostic tests performed to investigate the patient's musculoskeletal symptoms, including muscle biopsies, were revisited. Subsequent systematic investigations such as blood tests, liver ultrasound scan and Fibroscan® were performed to exclude potential causes of the deranged serum aminotransferases. Liver biopsy was not performed. A consistent pattern of chronic low-grade elevations of serum aminotransferases, less than three times the upper limit of the normal range, was found. This was associated with a consistently elevated serum creatine kinase and normal renal function tests. Previous muscle biopsies had revealed chronic degenerative and regenerative changes suggestive of a focal necrotizing myopathy. Liver ultrasound scan and Fibroscan® were normal. With exclusion of other liver diseases and identification of profoundly elevated serum creatine kinase concentration, the deranged aminotransferases were attributed to rippling muscle disease.

Los métodos empleados fueron AGID en suero, ELISA en muestras de suero y leche y PCR en linfocitos sanguíneos. De un total de 126 animales analizados, AGID identificó un menor número de animales positivos (75 comparado con las pruebas PCR y ELISA aplicadas en muestras de suero y leche (100. Tres animales positivos a AGID fueron negativos a PCR y 28 de las 51 muestras negativas a AGID fueron positivas mediante PCR. La sensibilidad diagnóstica de PCR con respecto a AGID fue de 96%, mientras que la especificidad fue de 45% (kappa 0,45. Todos los animales positivos a AGID fueron también positivos a ELISA aplicado tanto en suero como en leche, mientras que 25 animales negativos a AGID fueron consignados como positivos a ELISA, en ambas muestras biológicas. De esta forma, la sensibilidad diagnóstica de ELISA respecto a AGID fue de un 100%, mientras que la especificidad fue de 51% (kappa 0,55. La menor sensibilidad observada de AGID no es debido a reacciones falso positivas de ELISA y PCR, sino más bien a una mayor sensibilidad de estas últimas, lo que sugiere reconsiderar la utilización del método AGID en aquellos países en que aún se utiliza como método oficial en los programas de erradicación de leucosis.Different methods available for the detection of bovine leukaemia virus (BLV infection were evaluated.

    OBJECTIVE To study the effects of long-term training with different intensities on Perilpin and HSL in gene expression and blood serum in protein content among rat's skeletal muscle. METHODS 46 SD male rats were collected in adaptive training, and 6 rats were excluded. 40 rats were randomly divided into group C (sedentary control group), group L (low-intensity movement), group M (medium-intensity movement) and group N (high-intensity movement). The methods of Biochemistry and Rel-Time PCR were carried out to test the expression of ATGL and HSL. RESULTS Compared with Group C, FFA in the blood serum in each group was significantly higher (P < 0.05, P < 0.01). The HSL expression in the R and N groups significantly increased (P < 0.05). The expression of R gene expressed most. The Perilpin expression in R and N groups decreased (P < 0.05) , and expression of R gene express least. CONCLUSION The long-term training with different intensities can lead to the up-regulating of HSL in gene expression among rat's tibialis anterior and down-regulating of Perilipin in protein content. Medium intensity, especially the high-intensive long training, could dramatically improve the levels of Perilpin in gene expression. High-intensify training could enhance the HSL in gene expression and lower the content of peillipin, and enhance the fat hydrolysis ability in skeletal muscle.%目的 研究长期不同强度运动对大鼠胫骨前肌HSL、Perilipin基因表达及血清FFA含量的影响.方法 46只雄性SD大鼠,适应练习时淘汰6只.将40只大鼠随即分为安静对照组(C组)、中等耐力运动组(M组)、大强度运动组(N组)、抗阻训练组(R组).10周训练结束后采用生化方法测定各组大鼠血清FFA含量,RT- PCR法测定ATGL、HSL基因表达.结果 与C组相比,运动各组血清中FFA含量增加(P< 0.05,P< 0.01);R组、N组HSL基因表达上调(P<0.05),其中R组基因表达量最多;R组、N组Perilipin基因表达下调(P<0.05),其中
