    Full Text Available The implantation of the fertilized egg outside the uterine cavity leads to the development of ectopic pregnancy. The incidence of ectopic pregnancy is 1/100 births. The most common place of ectopic implantation of the fertilized ovum is the oviduct (98% with predilection for the ampullar part of the Fallopian tube. The aim of this study was to determine the predictive importance of beta-hCG and progesterone concentration compared to ultrasonographic finding in the ectopic pregnancy diagnosis.We examined 24 patients with ectopic pregnancies which we divided according to the days of amenorrhea into two groups: the first group with the total of 28 patients from 16–42 days and another group of 8 patients with amenorrhea longer than 42 days. The control group was comprised of 20 patients with vital intrauterine pregnancy, gestational age of 42-52 days. Blood samples for quantitative determination of hormones were collected on three occasions after 48 hours in the forenoon time in the examined and control group of pregnant women. Ultrasonographic examinations of all pregnant women were carried out immediately after blood sampling, with the trans-vaginal approach using "make loop" option, and measurements with an accuracy of 0.1 mm.Mean values for beta-hCG range from 698-1774 mlU/ml in the first group of pregnant women, and in the second group of 1896 mlU/ml to 4410 mlU/ml with a statistically significant difference compared to the values in the control group (p <0.001. The concentration of progesterone in the first group of women ranging from 41-70 nmol/l, and in the second group of 76-94 nmol/l which is also the statistically significant difference compared to the control group (p<0.002. We have shown that ultrasonographic finding with its parameters reliably predicts the values of biochemical parameters both in normal intrauterine pregnancy and in the case of ectopic pregnancy.Embryo viability and implantation place condition the values of

    The phenotype of women with PCOS changes with age. The study was aimed to address whether changes in biochemical parameters associated with age of the patients correlate with depression severity measured with the use of screening tools. This was a single center observational study. Women with PCOS meeting the Rotterdam criteria for PCOS were recruited. Hormonal and clinical parameters including symptoms of hyperandrogenism, age, BMI, androgen and blood lipids were analyzed in 60 patients (median age 27, median BMI 23 kg/m(2)) together with evaluation of depressive symptoms with the use Beck Depression Inventory, Patient Health Questionnaire-Nine Item (PHQ-9), Quick Inventory of Depressive Symptomatology-Self Report 16 Item (QIDS-SR16). The prevalence of depression was equal 22-33% depending on the questionnaire. The older women tended to present significantly higher BMI, SBP, waist circumference and lower androstenedione and DHEAS values than the younger group of patients. The prevalence of depression was higher in the group of older patients, however without statistical significance. Among the cohort of older patients (age ≥ 27 years, n = 29) significant correlates of depression included: nonHDL, LDL, HDL, total cholesterol (p waist circumference. Women with PCOS reporting depressive symptoms present higher levels of androgens and blood lipids. Clinicians treating women with PCOS should be aware that this group of patients is at increased risk of depression irrespectively of age and phenotype. Copyright © 2014 Elsevier Ireland Ltd.

    The lack of kinetic data concerning the biological effects of reactive oxygen species is slowing down the development of the field of redox signaling. Herein, we deduced and applied equations to estimate kinetic parameters from typical redox signaling experiments. H2O2-sensing mediated by the oxidation of a protein target and the switch-off of this sensor, by being converted back to its reduced form, are the two processes for which kinetic parameters are determined. The experimental data requ...

    Conclusions: Increased ox-LDL, hs-CRP, and e-NOS are likely to be a result of oxidative stress, a condition in which an imbalance occurs between the production and inactivation of reactive nitrogen and oxygen species. In addition, in patients with MetS, smoking is independently related to endothelial dysfunction.

    Aim of study: The aim of this study was to determine the effect of litter from Populus alba on chemical and biochemical properties related to the N cycle in soils with different pH values and trace element contents. We hypothesized that this litter would influence several parameters related to the N cycle and consequently to soil health. Area of study: we collected two reforested contaminated soils of different pH values (AZ pH 7.23 and DO pH 2.66) and a non-contaminated soil (RHU pH 7.19). Materials and methods: Soil samples were placed in 2,000 cm{sup 3} microcosms and were incubated for 40 weeks in controlled conditions. Each soil was mixed with its corresponding litter, and soils without litter were also tested for comparison. Ammonium (NH{sub 4}{sup 4}+-N) and nitrate (NO{sub 3}{sup -} -N) content, potential nitrification rate (PNR), microbial biomass nitrogen (MBN), protease activity, and several chemical properties such as pH, available trace element concentrations (extracted with 0.01 M CaCl{sub 2}) were determined at different times of incubation. Main results: Values of available trace elements did not vary during the incubation and were always higher in acid soil. In neutral soils litter presence increased values of Kjeldahl-N, NO{sub 3} –-N content, potential nitrification rate (PNR), microbial biomass nitrogen (MBN) and protease activity. Presence of trace elements in neutral soils did not alter the parameters studied. However, acidic pH and high content of available trace elements strongly affected NH{sub 4}{sup +}-N and NO{sub 3}{sup -} -N, microbial biomass N and protease activity. Research highlights: Our results showed the negative effect of the acidity and trace element availability in parameters related with the N-cycle. (Author)

    The purpose of this study was to evaluate the clinical effect on the biochemical inflammatory markers of a single oral high dose of cholecalciferol in vitamin D-deficient patients undergoing the surgical removal of lower third molars.A randomized, split-mouth, single-blind study was conducted on 25 vitamin D-deficient patients ranging between 18 and 40 years of age requiring lower third molars extraction and referred at the Oral Surgery Unit of the School of Dentistry of the University of Messina.All patients, with vitamin D3 blood levels ≦30 ng/mL, underwent bilateral surgical removal. The first extraction (control group) being conducted with the administration of a placebo, the second one (test group) being conducted with the preliminary administration of 300,000 IU of cholecalciferol 4 days before the procedure.At each surgery, clinical indexes, such as pain, edema and any functional limitation have been recorded. Clinical and biochemical parameters were registered 4 days before, immediately after, 3 and 7 days after the surgical procedure. The data obtained were processed using paired t-test. The clinical outcome parameters showed a slight to moderate improvement between the control and the vitamin-D treatment group, with statistical significance being obtained regarding the edema at defined time points. Interleukin-1-beta, interleukin-6, and tumor necrosis factor-alpha values were significantly lower (P surgery. The increase of vitamin D serum levels showed an impact on the outcome of the third molar surgery, eliciting a reduced inflammatory response and leading to a more favorable clinical course.

    2016-01-01

    Full Text Available Introduction. Combined use of bevacizumab and conventional anticancer drugs leads to a significant improvement of treatment response in patients with metastatic colorectal carcinoma (CRC. Conventional treatment protocols exert undesired effects on the liver tissue. Hepatotoxic effects are manifested as a disturbance of liver function test parameters. The relation between clinical outcome and disorder of biochemical parameters has not been completely evaluated. Objective. The objective of our study was to examine whether clinical outcome in patients with liver metastatic CRC correlates with the level of liver function test parameters. Methods. The study included 96 patients with untreated liver metastatic CRC who received FOLFOX4 protocol with or without bevacizumab. Biochemical liver parameters were performed before and after the treatment completion. Treatment response was evaluated as disease regression, stable disease, and disease progression. The patients were divided into three groups according to the accomplished treatment response. Results. In the group of patients with disease regression the post-treatment levels of aspartate aminotransferase, alanine aminotransferase, and bilirubin were statistically significantly increased. In contrast to this, gamma-glutamyltransferase and protein post-treatment values were significantly lower in relation to initial values. In patients with stable disease, difference was found only in the level of proteins being lower after the treatment. In patients with disease progression, values of aspartate aminotransferase and bilirubin were significantly increased after completed treatment. Conclusion. Treatment responses are not completely associated with the level of liver function test parameters. The only parameter which correlated with treatment response is gamma-glutamyltransferase. Its decrease is accompanied with disease regression.

    Full Text Available Abstract Background Glucose-dependent insulinotropic polypeptide (GIP is one of the incretins, which plays a crucial role in the secretion of insulin upon food stimulus and in the regulation of postprandial glucose level. It also exerts an effect on the synthesis and secretion of lipoprotein lipase, from adipocytes, important for lipid metabolism. The aim of our study was to do a case-control association analysis of common variants in GIP in association with type 2 diabetes and related biochemical parameters. Method A total of 2000 subjects which includes 1000 (584M/416F cases with type 2 diabetes and 1000 (470M/530F normoglycemic control subjects belonging to Dravidian ethnicity from South India were recruited to assess the effect of single nucleotide polymorphisms (SNPs in GIP (rs2291725, rs2291726, rs937301 on type 2 diabetes in a case-control manner. The SNPs were genotyped by using tetra primer amplification refractory mutation system-PCR (ARMS PCR. For statistical analysis, our study population was divided into sub-groups based on gender (male and female. Association analysis was carried out using chi-squared test and the comparison of biochemical parameters among the three genotypes were performed using analysis of covariance (ANCOVA. Result Initial analysis revealed that, out of the total three SNPs selected for the present study, two SNPs namely rs2291726 and rs937301 were in complete linkage disequilibrium (LD with each other. Therefore, only two SNPs, rs2291725 and rs2291726, were genotyped for the association studies. No significant difference in the allele frequency and genotype distribution of any of the SNPs in GIP were observed between cases and controls (P > 0.05. Analysis of biochemical parameters among the three genotypes showed a significant association of total cholesterol (P = 0.042 and low density lipoprotein (LDL with the G allele of the SNP rs2291726 in GIP (P = 0.004, but this was observed only in the case of female

    Xanthohumol (XN) is a hop flavonoid found in beers and refreshment drinks. Results of in vitro and animal studies indicate that it causes beneficial health effects due to DNA protective, anti-inflammatory, antioxidant, and phytoestrogenic properties. Aim of the present study was to find out if XN causes alterations of health-related parameters in humans. The effects of the flavonoid were investigated in a randomized crossover intervention trial (n = 22) in which the participants consumed a XN drink (12 mg XN/P/day). We monitored alterations of the DNA stability in single cell gel electrophoresis assays in lymphocytes and of several health-related biomarkers. A decrease of oxidatively damaged purines and protection toward reactive oxygen species induced DNA damage was found after the consumption of the beverage; also the excretion of 8-oxo-7,8-dihydro-2'-deoxyguanosine and 8-oxo-guanosine in urine was reduced. The assumption that the flavonoid causes DNA protection was confirmed in a randomized follow-up study with pure XN (n = 10) with a parallel design. Other biochemical parameters reflecting the redox- and hormonal status and lipid- and glucose metabolism were not altered after the intervention. Taken together, our data indicate that low doses of XN protect humans against oxidative DNA damage. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Preterm infants are at significant risk to develop reduced bone mineralization based on inadequate supply of calcium and phosphorus (Ca-P). Biochemical parameters can be used to evaluate the nutritional intake. The direct effect of nutritional intake on changes in biochemical parameters has not been studied. Our objective was to evaluate the effect of Ca-P supplementation on biochemical markers as serum (s)/urinary (u) Ca and P; alkaline phosphatase (ALP); tubular reabsorption of P (TrP); and urinary ratios for Ca/creatinin (creat) and P/creatinin in Very-Low-Birth-Weight infants on Postnatal Days 1, 3, 5, 7, 10, and 14. This observational study compared two groups with High ( n = 30) and Low ( n = 40) intake of Ca-P. Birth weight: median (IRQ) 948 (772-1225) vs. 939 (776-1163) grams; and gestational age: 28.2 (26.5-29.6) vs. 27.8 (26.1-29.4) weeks. Daily median concentrations of biochemical parameter were not different between the groups but linear regression mixed model analyses showed that Ca intake increased the uCa and TrP ( p = 0.04) and decreased ALP ( p = 0.00). Phosphorus intake increased sP, uP and uP/creat ratio and ALP ( p ≤ 0.02) and caused decrease in TrP ( p = 0.00). Protein intake decreased sP ( p = 0.000), while low gestational age and male gender increased renal excretion of P ( p < 0.03). Standardized repeated measurements showed that biochemical parameters were affected by nutritional intake, gestational age and gender.

    In this study, the seasonal variations in the morphometric features and in the cellular and biochemical parameters of the haemolymph were investigated in both male and female crabs (Carcinus aestuarii). Crabs were seasonally (November 2010-August 2011) collected from the Lagoon of Venice, and the moult stage, weight, width and length of the carapace, and width and length of the bigger chela were evaluated. In addition, the total haemocyte count (THC), haemocyte diameter and volume, haemolymph glucose and total protein levels, and haemolymph phenoloxidase (PO) and N-acetyl-β-glucosaminidase (NAG) activities were measured. The results demonstrated that the collected crabs were all in the intermoult stage and that the males were bigger than the females. A two-way ANOVA revealed a significant effect of season on the THC and the haemocyte volume and a significant influence of gender on the haemocyte diameter. Season and gender significantly affected the haemolymph glucose concentration, whereas haemolymph protein levels were dependent only on the season. In addition, both season and gender significantly influenced the PO and NAG activities in the haemolymph. Overall, the results demonstrated that crab morphometric features as well as haemolymph cellular and biochemical parameters varied markedly as a function of both season and gender.

  8. Leaf photosynthesis and respiration of three bioenergy crops in relation to temperature and leaf nitrogen: how conserved are biochemical model parameters among crop species?

    Given the need for parallel increases in food and energy production from crops in the context of global change, crop simulation models and data sets to feed these models with photosynthesis and respiration parameters are increasingly important. This study provides information on photosynthesis and respiration for three energy crops (sunflower, kenaf, and cynara), reviews relevant information for five other crops (wheat, barley, cotton, tobacco, and grape), and assesses how conserved photosynthesis parameters are among crops. Using large data sets and optimization techniques, the C(3) leaf photosynthesis model of Farquhar, von Caemmerer, and Berry (FvCB) and an empirical night respiration model for tested energy crops accounting for effects of temperature and leaf nitrogen were parameterized. Instead of the common approach of using information on net photosynthesis response to CO(2) at the stomatal cavity (A(n)-C(i)), the model was parameterized by analysing the photosynthesis response to incident light intensity (A(n)-I(inc)). Convincing evidence is provided that the maximum Rubisco carboxylation rate or the maximum electron transport rate was very similar whether derived from A(n)-C(i) or from A(n)-I(inc) data sets. Parameters characterizing Rubisco limitation, electron transport limitation, the degree to which light inhibits leaf respiration, night respiration, and the minimum leaf nitrogen required for photosynthesis were then determined. Model predictions were validated against independent sets. Only a few FvCB parameters were conserved among crop species, thus species-specific FvCB model parameters are needed for crop modelling. Therefore, information from readily available but underexplored A(n)-I(inc) data should be re-analysed, thereby expanding the potential of combining classical photosynthetic data and the biochemical model.

    Given the need for parallel increases in food and energy production from crops in the context of global change, crop simulation models and data sets to feed these models with photosynthesis and respiration parameters are increasingly important. This study provides information on photosynthesis and respiration for three energy crops (sunflower, kenaf, and cynara), reviews relevant information for five other crops (wheat, barley, cotton, tobacco, and grape), and assesses how conserved photosynthesis parameters are among crops. Using large data sets and optimization techniques, the C3 leaf photosynthesis model of Farquhar, von Caemmerer, and Berry (FvCB) and an empirical night respiration model for tested energy crops accounting for effects of temperature and leaf nitrogen were parameterized. Instead of the common approach of using information on net photosynthesis response to CO2 at the stomatal cavity (An–Ci), the model was parameterized by analysing the photosynthesis response to incident light intensity (An–Iinc). Convincing evidence is provided that the maximum Rubisco carboxylation rate or the maximum electron transport rate was very similar whether derived from An–Ci or from An–Iinc data sets. Parameters characterizing Rubisco limitation, electron transport limitation, the degree to which light inhibits leaf respiration, night respiration, and the minimum leaf nitrogen required for photosynthesis were then determined. Model predictions were validated against independent sets. Only a few FvCB parameters were conserved among crop species, thus species-specific FvCB model parameters are needed for crop modelling. Therefore, information from readily available but underexplored An–Iinc data should be re-analysed, thereby expanding the potential of combining classical photosynthetic data and the biochemical model.

    Full Text Available Abstract Background A prerequisite for the mechanistic simulation of a biochemical system is detailed knowledge of its kinetic parameters. Despite recent experimental advances, the estimation of unknown parameter values from observed data is still a bottleneck for obtaining accurate simulation results. Many methods exist for parameter estimation in deterministic biochemical systems; methods for discrete stochastic systems are less well developed. Given the probabilistic nature of stochastic biochemical models, a natural approach is to choose parameter values that maximize the probability of the observed data with respect to the unknown parameters, a.k.a. the maximum likelihood parameter estimates (MLEs. MLE computation for all but the simplest models requires the simulation of many system trajectories that are consistent with experimental data. For models with unknown parameters, this presents a computational challenge, as the generation of consistent trajectories can be an extremely rare occurrence. Results We have developed Monte Carlo Expectation-Maximization with Modified Cross-Entropy Method (MCEM2: an accelerated method for calculating MLEs that combines advances in rare event simulation with a computationally efficient version of the Monte Carlo expectation-maximization (MCEM algorithm. Our method requires no prior knowledge regarding parameter values, and it automatically provides a multivariate parameter uncertainty estimate. We applied the method to five stochastic systems of increasing complexity, progressing from an analytically tractable pure-birth model to a computationally demanding model of yeast-polarization. Our results demonstrate that MCEM2 substantially accelerates MLE computation on all tested models when compared to a stand-alone version of MCEM. Additionally, we show how our method identifies parameter values for certain classes of models more accurately than two recently proposed computationally efficient methods

    Full Text Available Background: Manganese (Mn related jobs may cause manganism especially in miners. Side effects include neural and pathological disorders. In spite of liver is the main organ that filters Mn (99% but few studies has performed about Mn toxicity in liver so no specific biochemical indicator is available (Gunnar. In this study, the relation between blood, urine and saliva Mn level and its hepatotoxic effects is evaluated. Materials and Methods: Blood, urine, saliva of 50 accidently selected miners collected in acid washed tubes for an experience study. Samples were used to evaluation not only biochemical parameters by pars azmoon kits but also Mn concentration by mass spectroscopy. Results: Manganese concentration in all miners in addition to blood AST, ALT, ALP increased significantly (p<0.001 related to controls. Miners with 10-15 years background had higher blood total, direct & indirect billirubin and ALP levels compared to others. Mn concentration in serum declined but in urine and saliva had no changes by working in mine. AST & ALT increased significantly in miners with 300 μg/L serum Mn concentration. Mn concentration in various samples and serum AST & ALT level were higher in native miners than non-native but in both not related to background. Conclusion: Significantly higher levels of billirubin, AST & ALT in miners compared to controls revealed Mn hepatotoxic effects in them. Also significant ALP increasing showed cholestasis in miners that supported by AST, ALT level. Significant billirubin, AST, ALT, ALP in miners with 10-15 years background revealed the importance of this period in miners liver check up. Higher Mn levels in different sources of native miners can be due to more environmental contact. Higher AST, ALT and lower ALP level in native miners indicate more hepatastoxic and less cholestasis and therefore arthrosclerosis and parkinson risk in these workers.

    Iran is a significant consumer of opium, and, generally, of opioids, in the world. Addiction is one of the important issues of the 21st century and is an imperative issue in Iran. Long-term consumption of opioids affects homeostasis. To determine the effects of opium and heroin consumption on serum biochemical parameters. In a cross-sectional study, subjects who had consumed heroin (n = 35) or opium (n = 42) for more than two years and 35 nonaddict volunteers as the control group were compared in regard to various biochemical parameters such as fasting blood sugar (FBS), Na(+), K(+), Ca(2+), blood urea nitrogen (BUN), uric acid (UA), triglyceride (TG), cholesterol, creatinine, and total protein. Chromatography was used to confirm opioid consumption, and the concentration of biochemical parameters was determined by laboratory diagnostic tests on serum. No significant differences were found in Na(+), Ca(2+), BUN, UA, TG, creatinine, and total protein concentrations among the three groups. FBS, K(+), and UA levels were significantly lower in opium addicts compared to the control group. Serum Ca(2+) concentration of heroin addicts showed a significant decrease compared to that of the control group. Both addict groups showed a significant decrease in serum cholesterol levels. Chronic use of opium and heroin can change serum FBS, K(+), Ca(2+), UA, and cholesterol. This study, one of few on the effects of opium on serum biochemical parameters in human subjects, has the potential to contribute to the investigation of new approaches for further basic studies.

    The type of fat in the diet determinates the characteristics of gut microbiota, exerting a major role in the development of metabolic syndrome. We hypothesize that a diet enriched with extra virgin olive oil (EVOO) has a distinctive effect on the intestinal microbiome in comparison with an enriched butter diet (BT) and this effect is related to the physiological benefits exerted by EVOO. Swiss Webster mice were fed standard (SD) or two high fat diets enriched with EVOO or butter. Hormonal, physiological and metabolic parameters were evaluated. At the end of the feeding period, DNA was extracted from faeces and the 16S rRNA genes were pyrosequenced. Among the main significant differences found, BT triggered the highest values of systolic blood pressure, correlating positively with the percentage of Desulfovibrio sequences in faeces, which in turn showed significantly higher values in BT than in EVOO. EVOO had the lowest values of plasmatic insulin, correlating inversely with Desulfovibrio, and had the lowest plasmatic values of leptin which correlated inversely with Sutterellaceae, Marispirillum and Mucilaginibacter dageonensis, the three showing significantly higher percentages in EVOO. The lowest total cholesterol levels in plasma were detected in SD, correlating positively with Prevotella and Fusicatenibacter, both taxa with significantly greater presence in SD. These results may be indicative of a link between specific diets, certain physiological parameters and the prevalence of some taxa, supporting the possibility that in some of the proposed effects of virgin olive oil the modulation of intestinal microbiota could be involved.

  3. Scalable Parameter Estimation for Genome-Scale Biochemical Reaction Networks

    2017-01-01

    Mechanistic mathematical modeling of biochemical reaction networks using ordinary differential equation (ODE) models has improved our understanding of small- and medium-scale biological processes. While the same should in principle hold for large- and genome-scale processes, the computational methods for the analysis of ODE models which describe hundreds or thousands of biochemical species and reactions are missing so far. While individual simulations are feasible, the inference of the model parameters from experimental data is computationally too intensive. In this manuscript, we evaluate adjoint sensitivity analysis for parameter estimation in large scale biochemical reaction networks. We present the approach for time-discrete measurement and compare it to state-of-the-art methods used in systems and computational biology. Our comparison reveals a significantly improved computational efficiency and a superior scalability of adjoint sensitivity analysis. The computational complexity is effectively independent of the number of parameters, enabling the analysis of large- and genome-scale models. Our study of a comprehensive kinetic model of ErbB signaling shows that parameter estimation using adjoint sensitivity analysis requires a fraction of the computation time of established methods. The proposed method will facilitate mechanistic modeling of genome-scale cellular processes, as required in the age of omics. PMID:28114351

    An astonishing scientific interest, embodied in over 15000 research articles so far, has been encountered since 1985 when fullerenes were discovered. From new superconductors to a rich electrochemistry and reaction chemistry, fullerene nanostructures continue to excite the scientific world, and new findings continue at record pace. This review presents many examples of the biochemical activities of fullerenes and derivatives, e. g. cytotoxic activity, selective DNA cleavage and antiviral activity against HIV. We also present some results of our testing which show that, despite its chemical and biochemical activity, fullerene matter does not present any health hazard directly related to skin irritation and allergic risks.

    Tartrazine and carmoisine are an organic azo dyes widely used in food products, drugs and cosmetics. The present study conducted to evaluate the toxic effect of these coloring food additives; on renal, hepatic function, lipid profile, blood glucose, body-weight gain and biomarkers of oxidative stress in tissue. Tartrazine and carmoisine were administered orally in two doses, one low and the other high dose for 30 days followed by serum and tissue sample collection for determination of ALT, AST, ALP, urea, creatinine, total protein, albumin, lipid profile, fasting blood glucose in serum and estimation of GSH, catalase, SOD and MDA in liver tissue in male albino rat. Our data showed a significant increase in ALT, AST, ALP, urea, creatinine total protein and albumin in serum of rats dosed with tartrazine and carmoisine compared to control rats and these significant change were more apparent in high doses than low, GSH, SOD and Catalase were decreased and MDA increased in tissue homogenate in rats consumed high tartrazine and both doses of carmoisine. We concluded that tartrazine and carmoisine affect adversely and alter biochemical markers in vital organs e.g. liver and kidney not only at higher doses but also at low doses.

    Full Text Available Background: The primary agricultural product in Egypt is the cotton crop. Children and adolescents work seasonally in the cotton fields applying pesticides. Objectives: To examine the effect of pesticide exposure on clinical and biochemical parameters in children and adolescents applying pesticides. Methods: Male children currently applying pesticides and aged between 9 and 19 years (n = 50 were recruited for this study. They were asked to complete work, health, and exposure questionnaires; examined for any medical and neurological problems with particular attention to sensory and motor functions including cranial nerves, sensory and motor system, and reflexes. From each participant, a blood sample was taken to measure acetylcholinesterase activity, and liver and kidney functions. Children who have never worked in agriculture (n = 50, matched on age, education, and socioeconomic status were also studied and served as controls. Results: More neuromuscular disorders were identified in pesticide applicators than controls. A significant lower level of acetylcholinesterase was found in the applicator group compared to the controls. There was also a significant difference in hematological, renal and hepatic indices in the exposed children compared to the control children. Working more days in the current season and also working more years as a pesticide applicator were both associated with an increase in the prevalence of neuromuscular abnormalities and significant changes in the laboratory tests. Conclusion: Children and adolescent pesticide applicators working in farms of Egypt are at risk of developing serious health problems similar to those of adults.

    Peel is a major by-product during processing of mango fruit into pulp. Recent report indicates that the whole peel powder ameliorated diabetes. In the present study, ethanolic extract of mango peel was analysed for its bioactive compounds, evaluated for α-amylase and α-glucosidase inhibitory properties, oral glucose tolerance test, antioxidant properties, plasma insulin level and biochemical parameters related to diabetes. In addition to gallic and protocatechuic acids, the extract also had chlorogenic and ferulic acids, which were not reported earlier in mango peel extracts. The peel extract inhibited α-amylase and α-glucosidase activities, with IC50 values of 4.0 and 3.5 μg/ml. Ethanolic extract of peel showed better glucose utilization in oral glucose tolerance test. Treatment of streptozotocin-induced diabetic rats with the extract decreased fasting blood glucose, fructosamine and glycated hemoglobin levels, and increased plasma insulin level. Peel extract treatment decreased malondialdehyde level, but increased the activities of antioxidant enzymes significantly in liver and kidney compared to diabetic rats. These beneficial effects were comparable to metformin, but better than gallic acid treated diabetic rats. The beneficial effects of peel extract may be through different mechanism like increased plasma insulin levels, decreased oxidative stress and inhibition of carbohydrate hydrolyzing enzyme activities by its bioactive compounds. Thus, results suggest that the peel extract can be a potential source of nutraceutical or can be used in functional foods and this is the first report on antidiabetic properties of mango peel extract.

    Infrared spectroscopy is gaining recognition as a promising method. The infrared spectra of selected regions (2000-400cm -1 ) of blood tissue samples are reported. Present study related to the role of spectral peak fitting in the study of human blood and quantitative interpretations of infrared spectra based on chemometrics. The spectral variations are interpreted in terms of the biochemical and pathological processes involved. The mean RNA/DNA ratio of fitted intensities and analytical area as calculated from the transmittance peaks at 1121cm -1 /1020cm -1 is found to be 0.911A.U and 2.00A.U. respectively. The ratio of 1659cm -1 /1544cm -1 (amide-I/amide-II) bands is found to shed light on the change in the DNA content. The ratio of amide-I/amide-II is almost unity (≅1.054) for blood spectra. The deviation from unity is an indication of DNA absorption from the RBC cells. The total phosphate content has found to be 25.09A.U. The level for glycogen/phosphate ratio (areas under peaks 1030cm -1 /1082cm -1 ) is found to be 0.286A.U. The ratio of unsaturated and saturated carbonyl compounds (C=O) in blood samples is in form of esters and the analytical areas under the spectral peaks at 1740cm -1 and 1731cm -1 for unsaturated esters and saturated esters respectively found to be 0.618A.U.

    Cypermetherin is widely used in Algeria; this insecticide belongs to the group of pyrethroids classified by the World Health Organization as moderately harmful class II (WHO, 2005). This study was conducted to search the effect of non lethal dose on biochemical parameters, hematological and histological parts of the organs. Male of domestic rabbits Oryctolagus cuniculus (1 kg) received per week and per gavage 1/10 LD50 of Cypermetherin (ARRIVO 25%, active substance of Cypermetherin 250 g/l). blood was collected 72 hours after the treatment. Enzyme activities were assayed in the plasma samples for Glutamate oxalo acetate transaminase (GOT), Glutamate pyruvate transaminase (GPT), Alcaline phosphatase (AlcP), creatinine (Crea) and glucose. Red blood (RBC) cells and white blood cells (WBC) were calculated too. The results indicated a significant increase in transaminases GOT and GPT, and AlcP explain a high energy generating product and dysfunction of the liver. A decline in Crea, Hb, RBC and WBC which is related to the immunity, this is probably due to cell lyses explain the effect of Cypermetherin on erythropoeisis. Histological examination confirmed the biochemical tests by the observation of inflammatory infiltrate and perilobular fibrosis. In conclusion, Cypermetherin with used dose affects biochemical, hematological and histological parameters of the rabbits.

    Compared to engineering or physics problems, dynamical models in quantitative biology typically depend on a relatively large number of parameters. Progress in developing mathematics to manipulate such multi-parameter models and so enable their efficient interplay with experiments has been slow. Existing solutions are significantly limited by model size. In order to simplify analysis of multi-parameter models a method for clustering of model parameters is proposed. It is based on a derived statistically meaningful measure of similarity between groups of parameters. The measure quantifies to what extend changes in values of some parameters can be compensated by changes in values of other parameters. The proposed methodology provides a natural mathematical language to precisely communicate and visualise effects resulting from compensatory changes in values of parameters. As a results, a relevant insight into identifiability analysis and experimental planning can be obtained. Analysis of NF-κB and MAPK pathway models shows that highly compensative parameters constitute clusters consistent with the network topology. The method applied to examine an exceptionally rich set of published experiments on the NF-κB dynamics reveals that the experiments jointly ensure identifiability of only 60% of model parameters. The method indicates which further experiments should be performed in order to increase the number of identifiable parameters. We currently lack methods that simplify broadly understood analysis of multi-parameter models. The introduced tools depict mutually compensative effects between parameters to provide insight regarding role of individual parameters, identifiability and experimental design. The method can also find applications in related methodological areas of model simplification and parameters estimation.

    Full Text Available The objective of this study was to assess the correlations of amylin (a pancreatic polypeptide hormone with some hormonal, biochemical and bone parameters in pullets. Forty 18-week-old pullets were used. Plasma amylin, CT (calcitonin, 1,25 (OH2 vitamin D (1,25 dihydroxycholecalciferol , serum osteocalcin, glucose, ALP (alkaline phosphatase, cholesterol, and triglycerides, as well as weight, length and total volume of tibiotarsi were measured. Plasma amylin concentration was negatively correlated with serum cholesterol (p<0.05 and triglycerides (p<0.05 concentrations. Plasma amylin concentration was significantly and positively correlated with plasma calcitonin concentrations (p<0.001. Serum ALP and plasma amylin concentrations were positively correlated (p<0.01. There were no correlations between amylin hormone and other parameters. Based on these results, it is possible to conclude that endogen amylin may effect cholesterol, triglycerides, calcitonin, and ALP levels in pullets without changing some other hormonal, biochemical and bone parameters related to calcium and lipid metabolism.

    Full Text Available Abstract Background The importance of stochasticity in cellular processes having low number of molecules has resulted in the development of stochastic models such as chemical master equation. As in other modelling frameworks, the accompanying rate constants are important for the end-applications like analyzing system properties (e.g. robustness or predicting the effects of genetic perturbations. Prior knowledge of kinetic constants is usually limited and the model identification routine typically includes parameter estimation from experimental data. Although the subject of parameter estimation is well-established for deterministic models, it is not yet routine for the chemical master equation. In addition, recent advances in measurement technology have made the quantification of genetic substrates possible to single molecular levels. Thus, the purpose of this work is to develop practical and effective methods for estimating kinetic model parameters in the chemical master equation and other stochastic models from single cell and cell population experimental data. Results Three parameter estimation methods are proposed based on the maximum likelihood and density function distance, including probability and cumulative density functions. Since stochastic models such as chemical master equations are typically solved using a Monte Carlo approach in which only a finite number of Monte Carlo realizations are computationally practical, specific considerations are given to account for the effect of finite sampling in the histogram binning of the state density functions. Applications to three practical case studies showed that while maximum likelihood method can effectively handle low replicate measurements, the density function distance methods, particularly the cumulative density function distance estimation, are more robust in estimating the parameters with consistently higher accuracy, even for systems showing multimodality. Conclusions The parameter

    The present study was conducted to determine the changes in concentrations of hormones and growth factors and their related receptor gene expressions in crop tissue, relative organ weight, and serum biochemical parameters in male and female pigeons during incubation and chick-rearing periods under artificial farming conditions. Seventy-eight pairs of 60-week-old White King pigeons with 2 fertile eggs per pair were randomly divided into 13 groups by different breeding stages. Serum prolactin and insulin-like growth factor-1 (IGF-1) concentrations in crop tissue homogenates were the highest in both male and female pigeons at 1 d of chick-rearing (R1), while epidermal growth factor (EGF) in female pigeons peaked at d 17 of incubation (I17) (P < 0.05). mRNA expression of the prolactin and EGF receptors in the crop tissue increased at the end of incubation and the early chick-rearing stage in both sexes. However, estrogen, progesterone, and growth hormone receptor expression each decreased during the early chick-rearing stage (P < 0.05). In male pigeons, IGF-1 receptor gene expression reached its peak at R7, while in female pigeons, it increased at the end of incubation. The relative weight of breast and abdominal fat in both sexes and thighs in the males was lowest at R7, and then gradually increased to the incubation period level. Serum total protein, albumin, and globulin concentrations increased to the highest levels at I17 (P < 0.05). Total cholesterol, triglyceride, and low-density lipoprotein reached their highest values at I17 in male pigeons and R25 in female pigeons (P < 0.05). In conclusion, hormones, growth factors, and their receptors potentially underlie pigeon crop tissue development. Changes in organs and serum biochemical profiles suggested their different breeding-cycle patterns with sexual effects.

    The effect of single acute oral doses of 29 and 58 mg/kg of cyanox (an organophosphorus pesticide) on selected biochemical and hematological parameters in male rats were investigated. This compound inhibited blood acetylcholine esterase (AChE) significantly, over 72 hours post-treatment with the higher dose level. Serum alkaline phosphatase (ALP) was significantly depressed, 48 hr after treatment with 58 mg/kg. Serum bilirubin was elevated significantly after 48 and 24 hr of treatment with 29 and 58 mg/kg, respectively. Serum cholesterol increased significantly over 48 hr post-treatment with both dose levels.Hypertriglyceridemia was noticed only in the higher dose group. Serum total lipids were increased significantly at both dose levels. A slight treatment-related effect was observed in serum creatinine level. The hematological investigations revealed the occurrence of macrocytic normochromic anemia that was more evident in the lower dose group

    Full Text Available Africa is rich in a wide range of flora that are exploited as herbal medicines and remedies. Several diseases such as diabetes, diarrhea, dysentery and jaundice have been successfully managed using herbal medicines. Herbal decoctions or concoctions have been used as pain killers, antibiotics, and hematinics. This study evaluated the hematopoietic and biochemical properties of the stem bark of Sterculia setigera Del. in Wistar rats. Results showed that S. setigera decoction has copiously high tannin and cardiac glycoside levels. Ingestion of the decoction by rats over a 16-day period significantly ( P < 0.05 increased the body weights of rats by 22.4% in the S. setigera -treated group. Hematological profiles showed raised levels of red blood cells, hemoglobin, packed cell volume, mean corpuscular volume, mean cell hemoglobin, mean cell hemoglobin concentration, and platelets, while biochemical parameters showed lower levels of alanine aminotransferase and aspartate aminotransferase, and slight increase in albumin and TP levels. We posit that the results justify the use of the stem bark of S. setigera as a hematinic by traditional medical practitioners and show its relative safety. Further experiments are needed to evaluate its safety.

    Full Text Available This study was aimed at selected blood biochemical parameters in the male American mink before (September-November and during the breeding (January-March season. Blood from 143 Black and Sapphire male mink at one year age was collected. The plasma was assayed for the concentration of glucose, total protein, cholesterol, HDL and LDL fractions, triacylglycerides (TG, and the activity of ALT and AST. Concentrations of glucose, protein, total and HDL/LDL cholesterol, and AST activity were generally slightly higher during the breeding season than during the non-breeding season, but remained within the reference range. In the case of ALT activity and TG concentration, the relations were reversed. The parameters studied in the Sapphire mink showed greater variation, both in- and out of the season. In Black and Sapphire males of the American mink, the studied parameters revealed slightly higher values during the breeding season than the non-breeding season. This will vary depending on the color variety. The decrease in TG concentration during the breeding season may indicate an increased energy demand due to ambient temperature falls, and/or may be a sign of increased energy consumption associated with physical exertion during mating. Consideration should be given to the nutrition of male mink during the breeding season.

    Forty two healthy Egyptian women were participated in this study to evaluate the effect of early and late menopause on some biochemical and hormonal parameters. The women were divided into three equal groups. The first was the pre-menopausal group with regular menstrual cycle, the second was the late menopausal group comprised the menopausal female less than 5 years and the third group consisted of women that became menopause since 5-9 years. The second and third groups had almost the same age and body weight. After clinical examination, fasting blood samples were collected from all volunteers. Regarding the pre-menopausal women, blood was withdrawn between the 3 rd and the 5 th day post-menstruation (follicular phase). Follicle stimulating hormone (FSH), leutinizing hormone (LH), progesterone, prolactin (PRL), testosterone, leptin and thyroxine (T4) in addition to hemoglobin (Hb), blood glucose, calcium (Ca), inorganic phosphorous (P), magnesium (Mg) and uric acid were determined. Both menopausal groups showed significant increase in FSH and LH and significant decrease in PRL and late menopausal group experienced also multiple significant correlations between FSH, LH and other tested parameters. Prolongation of menopause exhibited decrease in leptin being significant as compared to pre-menopausal women than that experienced menopause at younger age. Due to the relation between leptin hormone and osteoporosis, the results of this investigation denoted that early cessation of annulations (menopause) in Egyptian women may lead to disturbance in bone metabolism causing inhibiting osteoblastogenesis and decreasing bone mass.

    Full Text Available The health status of cows is evaluated and depending on haematological and biochemical profile of blood. Nutrition is the main technological factor that can produce profound changes in the metabolic profile in animals (Dhiman et al., 1991; Khaled et al., 1999; Ingvartsen, 2006. Blood parameters analyze can lead to identify if there are errors in nutrition of lactating cows (Payne et al., 1970. The aim of this study was the evaluation of metabolic and biochemical changes that occur during colostrum period and in terms of number of lactations in cows. The biological material was represented by a total of 60 heads of dairy cows from a family farm from Sălaj County, Romania. The cows are all from Holstein breed and presented no clinical signs of any specific pathology. Blood samples were collected from the jugular vein of each cow and analyzed. 10 individuals from each of the six lactations have been randomly selected. Haematological and biochemical parameters showed variations depending on factors analyzed here. In lactation 1 Hb was 7.55±3.05 (g/dl, while in lactation 6 the value was 12.5±2.10 (g/dl. RBC ranged as follows: in lactation 1 - 28.50±2.05 and in lactation 6 - 30.02±2.05. Lymphocytes varied within very wide limits under the influence of lactation: in lactation 1 - 2.8±1.56 and in lactation 6 - 7.55±1.80. The number of lactations and lactation rank have influenced blood biochemical and hematological parameters in dairy cows. Biochemical parameters are influenced by post-partum day, showing the lowest values in the early days of colostral period and the highest in the last few days of the same period.

    Most of the previously obtained data on cosmonauts' metabolic state concerned certain stages of the postflight period. In this connection, all conclusions, as to metabolism peculiarities during the space flight, were to a large extent probabilistic. The purpose of this work was study of metabolism characteristics in cosmonauts directly during long-term space flights. In the capillary blood samples taken from a finger, by "Reflotron IV" biochemical analyzer, "Boehringer Mannheim" GmbH, Germany, adapted to weightlessness environments, the activity of GOT, GPT, CK, gamma-GT, total and pancreatic amylase, as well as concentration of hemoglobin, glucose, total bilirubin, uric acid, urea, creatinine, total, HDL- and LDL cholesterol, triglycerides had been determined. HDL/LDL-cholesterol ratio also was computed. The crewmembers of 6 main missions to the "Mir" orbital station, a total of 17 cosmonauts, were examined. Biochemical tests were carryed out 30-60 days before lounch, and in the flights different stages between the 25-th and the 423-rd days of flights. In cosmonauts during space flight had been found tendency to increase, in compare with basal level, GOT, GPT, total amylase activity, glucose and total cholesterol concentration, and tendency to decrease of CK activity, hemoglobin, HDL-cholesterol concentration, and HDL/LDL — cholesterol ratio. Some definite trends in variations of other determined biochemical parameters had not been found. The same trends of mentioned biochemical parameters alterations observed in majority of tested cosmonauts, allows to suppose existence of connection between noted metabolic alterations with influence of space flight conditions upon cosmonaut's body. Variations of other studied blood biochemical parameters depends on, probably, pure individual causes.

    The effects of long-term (1 yr) exposure to low doses of cadmium (Cd) dissolved in drinking water on selected biochemical and antioxidant parameters were studied in Wistar rats. Rats were divided into four groups: male control group (C-m), female control group (C-f), male Cd-exposed group (Cd-m), and female Cd-exposed group (Cd-f). Cd groups were exposed to Cd dissolved in drinking water (cadmium dichloride 4.8 mg CdCl2/L, i.e., 2.5 mg Cd/L, 500-fold of maximal allowable concentration for potable water). The experiment was terminated on d 370. In all groups, biochemical parameters (total protein [TP], albumin, alanine aminotransferase, aspartate aminotransferase, glucose, cholesterol, triacylglycerols, urea, and creatinine) and antioxidant parameters (glutathione peroxidase, superoxide dismutase, and total antioxidant capacity) were measured in the blood. Total protein and albumin concentrations were decreased significantly in the Cd-m group. Other biochemical parameters did not change in Cd groups compared to control groups. Superoxide dismutase fell significantly in both male and female Cd-exposed groups. Activity of glutathione peroxidase was markedly lower in Cd-exposed groups. Total antioxidant capacity increased significantly in Cd-f group. These results suggest that chronic low-dose oral Cd exposure induces oxidative stress.

    During choledocholitiasis inflammatory oxidant stress involves the promotion of mitochondrial dysfunction through an intracellular oxidant stress in hepatocytes leading mainly to necrosis and less to apoptosis. The product of oxidative stress, malondialdehyde (MDA), is extremely cytotoxic and damages cell membranes and intracellular macromolecules. The toxicity of MDA is based on its ability to act as a mutagenic agent in a cell. Therefore, the aim of this prospective study was to establish correlation of the parameters of inflammation and biochemical markers of cholestasis with the intensity of oxidative stress in pathogenesis of liver function disorders. Seventy adult subjects of either sex included in the study were devided into two groups: I--40 patients with obstructive icterus caused by choledocholithiasis, and II--30 healthy individuals. All the participants were subjected to a clinical, laboratory and ultrasonic check-up at the Internal Department of the Military Hospital in Nis. The parameters of oxidative stress: MDA, a measure of lipid peroxidation, and inflammation parameters: C-reactive protein (CRP), fibrinogen, albumins, number of leukocytes (Leu), granulocytes (Gr), lymphocytes (Ly) and monocytes (Mo) and biochemical markers of cholestasis: activity of gamma-glutamyltransferase (gamma-GT) and alkaline phosphatase (AP) enzymes, the level of total, direct and indirect bilirubin were determined by standard biochemical methods. Lower values of albumin (p choledocholithiasis in relation to the controls. Significantly higher values of Leu (p choledocholithiasis in relation to the control. Similarly, higher values of gamma-GT, and AP (p choledocholithiasis in relation to the controls. The concentration of MDA (p choledocholithiasis in relation to the controls. There was a significant positive linear correlation of the number of leukocytes (r = 0.51, p choledocholithiasis.

    Passiflora alata (Passifloraceae) is a native plant from the South-America tropical forest that provides a much appreciated fruit known as "maracujá-doce". Although tea of the leaves of Passiflora alata is used in folk medicine as a sedative and tranquilizer, there are no investigations about its effects on biochemical parameters in blood or from its major chemical composition. The purpose of this study was to evaluate the effects of the tea of the leaves of Passiflora alata on biochemical parameters (antioxidant system, glucose and cholesterol levels) and to perform a phytochemical investigation of the tea. We isolated and identified two saponins and five C-glycosylflavones derived from apigenin, luteolin and chrysoeriol. Three of them are new in this species. Passiflora alata extract was administrated orally in rats at dose of 1000 mg/kg and it was observed an increase in high-density lipoprotein level (HDL-cholesterol).

    While anti-oxidant effects of Moringa oleifera in much oxidative stress related diseases have been well reported, cryptorchidism on the other hand has been shown to cause oxidative stress. However, study is scanty on the likely role of Moringa oleifera in reducing cryptorchidism-induced oxidative stress in rats has not been studied. The present study looked into the effects of methanolic extract of Moringa oleifera leaves (MEMO) on semen and biochemical parameters in cryptorchid rats. Twenty male albino rats (200-250 g) were randomly divided into 4 groups (n=5 each). Groups A and B were sham-operated and treated with corn-oil and 200 mg/kg of MEMO respectively, while groups C and D were rendered cryptorchid and also treated with corn-oil and 200 mg/kg of MEMO respectively. Cryptorchid rats had lower testicular weight, sperm count, germ cell count, testicular superoxide dismutase (SOD) concentration, testicular total protein and higher testicular malondialdehyde (MDA) concentration compared to sham-operated rats. MEMO had no significant effect on testicular weight and MDA concentration, while it significantly increased sperm count, germ cell count, testicular SOD and total protein in the cryptorchid rats. The present study suggests that MEMO ameliorates cryptorchidism associated germ cell loss and oxidative stress.

    Full Text Available The development of selected haematological and biochemical parameters during the laying period was monitored in common pheasant hens housed in an enhanced cage system. The cages were enhanced by the addition of two perches and a shelter formed by strips of cloth hanging in the corner of the cage. The results showed significant changes in the haematological and biochemical parameters monitored during egg laying. At the time when laying capacity approached a maximum, a decrease was observed (P<0.05 in haematocrit, erythrocytes, and haemoglobin values, whereas monocytes, eosinophils, the heterophil/lymphocyte ratio, phosphorus, and calcium exhibited an increase (P<0.05. At the end of the laying period, an increase (P<0.05 was recorded in the count of leukocytes, heterophils, lymphocytes and basophils, the heterophil to lymphocyte ratio, and the concentrations of aspartate aminotransferase, cholesterol, phosphorus, and calcium, whereas lower values (P<0.05 were recorded for haematocrit and plasma total protein in comparison with the values of the indicators at the beginning of the laying period. The results provide new information about dynamic changes in selected haematological and biochemical parameters in clinically healthy common pheasant hens during the laying period.

    Turmeric, (Curcuma ionga), is a dietary antioxidant and has been known since ancient times to possess therapeutic properties. The present investigation examined the correlation between raw and irradiated turmeric powder (at dose levels of 10, 15 and 20 kGy) intake and the physiological effects on organs weight, haematological parameters, indices of liver function and lipid profile in growing Albino male rats. Also, this study was performed to examine the efficacy of radiation processed turmeric powder to modulate the induced hyperlipidaemia in growing Albino male rats. Thirty six male rats were equally and randomly categorized into six groups. Control group fed a reference diet (casein diet), high fat diet was daily received to rats for 6 weeks. Other animals fed daily on high fat diets containing either raw or irradiated turmeric powder (2 g per 100 g diet) at doses 10, 15 or 20 kGy for 6 weeks. The results showed that the relative spleen, kidneys, heart, lungs, and testes weight, and the levels of Hb, PCV and MCHC were not changed in animals fed the experimental diets for 6 weeks. Animals kept on HFD suffered from liver enlargement. Dietary interventions through administrating 2% (w/w) raw or irradiated turmeric powder at 20 kGy normalized the liver size as compared with those received reference diet. Meanwhile, the results revealed that rats fed on high fat diet significantly increased plasma AST, ALT, TC and TG and significant decrease was observed in HDL. Meanwhile, feeding rats on diet containing of either raw or irradiated turmeric powder at 10, 15 and 20 kGy induced a significant improvement in the above mentioned parameters. These results imply that irradiated turmeric powder at 20 kGy can offer protection against the biochemical changes as a consequence of hyperlipidaemic food and contribute to the regulation of lipid metabolism safely

    Full Text Available ABSTRACT This study aimed to provide baseline data for the serum biochemical parameters of Brazilian sport horses undergoing physical training for eventing to be used as a practical guide. A total of 139 blood samples were collected by vacuum venipuncture of the jugular vein from healthy horses in training. Tubes without anticoagulant were used for biochemical analysis. Means and standard deviations were determined for aspartate aminotransferase (AST (306.27±84.66 U/L, creatine kinase (CK (181.06±80.38 U/L, urea (29.51±5.82 mg/dL, creatinine (1.44±0.20 mg/dL, gamma glutamyl transferase (GGT (14.58±6.55 U/L, calcium (13.22±0.59 mg/dL, and albumin (2.86±0.16 g/dL. The specific reference ranges were: AST, 197-454 U/L; CK, 116-290 U/L; urea, 22-42 mg/dL; creatinine, 1.2-1.8 mg/dL; GGT, 9-26 U/L; calcium, 12.2-14.2 mg/dL; and albumin, 2.6-3.1 g/dL. Beneficial effects of the training program on the horses were observed and these effects did not lead to any changes in the biochemical parameters studied. The environment may influence the serum biochemical parameters, particularly AST and CK, of Brazilian sport horses.

    Garlic extract has various medical effects on the treatment of many diseases as hypertension, atherosclerosis, inflammation and diabetes. The alteration of the biochemical parameters in blood serum of irradiated rats may play an important role in determining the pathogenesis of radiation exposure. Many of the damaging effects of ionizing radiation are mediated by reactive free radicals. This study was designed to evaluate the protective role of garlic against gamma irradiation (5Gy) induced biochemical disorders in rats. Samples were collected at 1, 7 and 14 days post-irradiation. Lipid peroxide content (malondialdehyde), cholesterol, HDL-C, LDL-C, fatty acids, glucose, insulin, glycogen, haemoglobin, ferritin andiron were estimated.Garlic was orally administered to rats (100 mg/kg body weight) for 14 days before exposure to single dose of gamma irradiation at dose level 5 Gy. The data revealed significant increase in the levels of lipid peroxide, cholesterol, LDL-cholesterol, fatty acids, insulin, glucose and iron accompanied with significant decrease in the levels of HDL-cholesterol, glycogen, haemoglobin and ferritin due to radiation exposure. Administration of garlic alone to the rats caused nonsignificant changes in the estimated parameters indicating its safe use, but the treatment with garlic to rats before radiation exposure ameliorated the changes induced by gamma irradiation and tended to normalize their levels.It could be concluded that garlic administration may has a beneficial role in restoring the biochemical disorders induced by 5 Gy gamma irradiation

    The activity of aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase, total protein, albumin and cholesterol levels were determined in the blood serum of Japanese quails infected with coccidia and treated with Baycox (active ingredient: toltrazuril). Lower levels of AST and ALT activity were noted in treated birds regardless of the applied Baycox dose. The biochemical changes observed in the blood serum of Japanese quails point to coccidia-induced damage of digestive system tissues despite an absence of pronounced clinical symptoms. Significantly lower levels of AST activity and higher levels of LDH activity in treated birds indicate that coccidiosis treatment with toltrazuril contributed to the regeneration of digestive system tissues. An insignificant increase in cholesterol levels was noted, whereas the other serum biochemical parameters remained within the reference ranges.

    Aflatoxins are toxic fungal metabolites that have adverse effects on humans and animals. Tarantula cubensis D6 is used as a homeopathic medicine for different purposes. The present study investigates the effects of Tarantula cubensis D6 on the oxidant-antioxidant balance and some biochemical parameters against exposure to aflatoxin. Thirty-two Sprague-Dawley female rats were used and evenly divided into four groups. Group 1 served as control. Groups 2, 3, and 4 received 200 μl/kg.bw/day Tarantula cubensis D6 (applied subcutaneously), 400 μg/kg.bw/day total aflatoxin (approximately 80% AF B1, 10% AF B2, 6 %AF G1, and 4% AF G2), and 200 μl/kg.bw/day Tarantula cubensis D6 plus 400 μg/kg.bw/day total aflatoxin, respectively, for 28 days. At the end of 28 days, blood samples and some organs (liver, kidney, brain, and spleen) were taken from all the animals. Oxidative stress markers (MDA, SOD, CAT, GSH-Px) and some biochemical parameters (glucose, triglyceride, cholesterol, BUN, creatinine, AST, ALT and ALP, total protein, albumin) were evaluated in blood samples and tissues. Aflatoxin caused negative changes in all oxidative stress parameters and some biochemical parameters (glucose, triglyceride, cholesterol, creatinine, AST, ALT, ALP, total protein, albumin). Administration of Tarantula cubensis D6 partly alleviated aflatoxin-induced negative changes. Our results indicated that Tarantula cubensis D6 partially neutralized the deleterious effects of aflatoxin. Copyright © 2015 The Faculty of Homeopathy. Published by Elsevier Ltd.

    To estimate the reference intervals for commonly used blood haematology and biochemical parameters in an adult (18-55yrs) population of residents of Mampong Akuapem. This was a population based cross sectional study of a randomly selected sample of the adult population of Mampong. The sample was selected from an updated census list of the Mampong area. Median values (95% range) for measured parameters were established as follows: Haemoglobin, (males) 14.2 g/dl (females) 12.0 g/dl Alanine aminotransferase (ALT), (female) 19.6 U/L (males) 26.1 U/L and Creatinine, (males) 108 mmol/L (females) 93 mmol/L. In comparison to reference values that are commonly used in Ghana, the haemoglobulin levels from this study were lower, and liver function parameters higher. This could be a result of genetic or environmental differences and calls for the need to establish site specific reference values applicable to our population.

    Metals are released into aquatic systems from many sources, often at sublethal concentrations. The effects of sublethal concentrations of metals on fish are not entirely understood. The objective of this study was to determine the hematological and biochemical effects of a range of copper concentrations (6.4, 16.0, 26.9 ??g Cu/L) on rainbow trout (Oncorhynchus mykiss) over a prolonged period of time. Trout were exposed to copper, and, at intervals of 3, 7, 14, and 21 days, selected parameters were evaluated. Hemoglobin, hematocrit, plasma glucose, and plasma cortisol levels were elevated in trout exposed to 26.9 ??g Cu/L at day 3 and then returned to levels comparable to control fish. Plasma protein and lactate levels were not significantly altered in trout from any copper treatment. Hepatic copper concentration and hepatic metallothionein mRNA expression were consistently elevated in trout exposed to 26.9 ??g Cu/L. Both of these parameters stabilized by day 3, with only hepatic copper concentration showing a further increase at day 21. Hepatic copper concentration and hepatic metallothionein mRNA expression appear to be robust indicators of copper exposure. Most blood-based parameters evaluated appear to be associated with a transitory, nonspecific stress response. The return of elevated hematological and biochemical parameters to control levels after 3 days and thestabilization of hepatic metallothionein mRNA expression and copper concentration over a similar time period suggested acclimation to dissolved copper at 26.9 ??g/L. Further analysis of the data on blood-based parameters indicated that certain parameters (hemoglobin, hematocrit, plasma glucose, plasma cortisol) may be useful in field monitoring.

    Full Text Available Ten grape rootstocks were subjected to moisture and salinity stress in two separate experiments. The influence of these stresses on gas exchange, water relation, and biochemical parameters was monitored at various stages of stress cycle. Both stresses indicated significant changes in the physiological and biochemical parameters studied. Some biochemical constituents increased by several folds in few rootstock cultivars which also recorded increased osmotic potential suggesting their role in osmotic adjustment. Some of the rootstock cultivars such as 110R, 1103P, 99R, Dogridge, and B2/56 recorded increased phenolic compounds under stressed conditions. The same rootstock also recorded increased water use efficiency. The increased accumulation of phenolic compounds in these cultivars may indicate the possible role of phenolic compounds as antioxidants for scavenging the reactive oxygen species generated during abiotic stresses thus maintaining normal physiological and biochemical process in leaves of resistant cultivars.

    Full Text Available The aim of this study was to present the performance and some biochemical parameters in the blood of hens fed feed mixtures with different levels of lutein. The study involved a total of 291 Tetra SL hybrid laying hens, divided into 3 groups (O0 with 0 mg/kg lutein added, O200 with 200 mg/kg lutein added and O400 with 400 mg/kg lutein added, and lasted for 5 weeks. The O0 group included 93 hens, whereas experimental groups 98 and 100 hens, respectively. The highest egg production and the best feed consumption per egg were recorded in O400 group with a total of 3367 pieces of eggs produced and 128.60 g of feed consumed. The best laying intensity (96.68% and number of eggs per laying hen (34.19 as well as the highest feed consumption per day (129.01 g, was recorded in O200 group. Lutein added to feed mixtures for laying hens did not significantly affect the values of biochemical parameters in blood (P>0.05. An increase in total cholesterol (CHOL and HDL cholesterol content as well as the decrease of total protein (PROT and albumin (ALB content in the experimental groups can be observed. The content of glucose (GUK and urea was similar between the experimental groups, while the highest content of triglycerides (TGC was recorded in O200 group. It can be concluded that different levels of lutein added to the feed mixtures for laying hens did not have negative effect on the performance and blood biochemical parameters of laying hens.

    Aim: To investigate the influence of season on erythrocyte picture, plasma enzyme and electrolyte profile of local pig of Mizoram at a different age. Materials and Methods: A volume of 2 ml of blood samples were collected from 72 Zovawk pigs of three different age groups viz. pre-weaning, grower and adult pigs reared in College of Veterinary Sciences and Animal Husbandry Selesih, Aizawl, Mizoram, India, livestock farm during summer and winter in order to find out influence of season on erythrocyte picture, enzyme and electrolyte profile. The hematological parameters were estimated by using an automatic blood analyzer. The biochemical parameters were estimated by using diagnostic kits. Results: The grower pigs had lower hemoglobin (Hb), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular Hb (MCH) during summer, rainy and winter seasons (p<0.05) and lower MCH concentration (MCHC) during summer season (p<0.05). Adult pigs had lower Hb with higher total erythrocyte count in rainy season. PCV and MCV of adult pigs decreased in summer (p<0.05). Serum glutamic oxaloacetic transaminase activity of both the grower and adult groups increased during summer and rainy seasons (p<0.05). Zovawk pigs had higher sodium (Na) and lower potassium (K) in rainy season (p<0.05). Pre-weaning piglets had higher Na, K, calcium (Ca), and magnesium (Mg) in summer than in winter. Grower pigs had higher Na, K and Ca in summer (p<0.05). Pi of pre-weaning and grower groups was higher in winter. Adult pigs had lower alkaline phosphatase activity and Ca in summer and higher Pi and Mg in winter (p<0.05). Conclusion: Seasonal variation in some hemato-biochemical parameters of Zovawk pig were investigated. Influence of season on the hemato-biochemical profile was most evident during the grower stage, followed by adults and pre-weaning piglets. PMID:27065639

    Full Text Available Residual renal function (RRF is an important prognostic factor for peritoneal dialysis patients as it influences the quality of life and mortality. This study was conducted to explore the potential factors correlated with RRF. A cross-sectional study was conducted by recruiting 155 patients with residual GFR more than 1mL/min per 1.73m2 at the initiation of peritoneal dialysis. We collected the demographic characteristics, nutritional markers and biochemical parameters of all participants, and analyzed the correlation between these variables and residual GFR as well. The odds ratio of RRF loss associated with each of the nutritional markers and biochemical parameters were estimated by logistic regression model. The residual GFR was negatively correlated with serum phosphate (ORQ3 = 2.67, 95%CI: 1.03-6.92; ORQ4 = 3.45, 95%CI: 1.35-9.04, magnesium (ORQ4 = 3.77, 95%CI: 1.48-3.63, and creatinine (ORQ3 = 2.93, 95%CI: 1.09-7.88; ORQ4 = 8.64 95%CI: 2.79-26.78, while positively associated with normalized protein catabolic rate (ORQ3 = 0.24, 95%CI: 0.09-0.65; ORQ4 = 0.11, 95%CI: 0.03-0.35, 24 hours urine volume(ORQ1 = 22.87, 95%CI: 2.76-189.24; ORQ3 = 0.08, 95%CI: 0.02-0.28 and serum chlorine concentrations (ORQ1 = 5.34, 95%CI: 1.94-14.68; ORQ4 = 0.28, 95%CI: 0.09-0.85, respectively. Our study suggested that the nutritional markers and biochemical parameters, though not all, but at least in part were closely correlated with RRF in peritoneal dialysis patients.

    Full Text Available Abstract Background Firefighters who are facing fires, are frequently exposed to hazardous materials including carbon monoxide, hydrogen cyanide, hydrogen chloride, benzene, sulphur dioxide, etc. This study aimed to evaluate some relevant serum biochemical and blood hematological changes in activity involved firefighters in comparison to normal subjects. Subjects and Methods Two groups of male firefighters volunteered to participate in the study. The first included 28 firefighters from Jeddah, while the second included 21 firefighters from Yanbu, with overall age ranged 20–48 years. An additional group of 23 male non-firefighters volunteered from both cities as normal control subjects, of age range 20–43 years. Blood samples were collected from all volunteer subjects and investigated for some relevant serum biochemical and blood hematological changes. Results The results obtained showed that, there were statistically significant differences in liver function, kidney function, serum lipid profile, cortisol, creatine kinase, lactate dehydrogenase, iron and its biologically active derivatives, and blood picture in firefighters as compared with the normal control group. These results indicate that, fire smoke mainly affects serum biochemical and blood hematological parameters. Such results might point out to the need for more health protective and prophylactic measures to avoid such hazardous health effects that might endanger firefighters under their highly drastic working conditions. Conclusion Besides using of personal protective equipments for firefighters to protect them against exposure to toxic materials of fire smoke, it is recommended that, firefighters must be under continuous medical follow up through a standard timetabled medical laboratory investigations to allow for early detection of any serum biochemical or blood hematological changes that might happen during their active service life and to allow for early treatment whenever

    Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a frequently diagnosed condition in adult horses. The underlying etiology is still unknown. Hematologic, biochemical, and endocrine values have not been reported in EOTRH-affected horses. The main objective of the study was to describe the hematologic, biochemical, and endocrine parameters in horses with EOTRH. Descriptive cross-sectional study of client-owned animals with EOTRH. A complete blood count, biochemistry panel, and endocrine profile were performed in horses diagnosed with EOTRH. Diagnosis was based on oral and radiographic examination findings and confirmed with histopathology. Eighteen horses with EOTRH aged 10 to 32 years from various regions of the United States were sampled. The only consistent abnormality on the complete blood cell count and chemistry panel was hypoalbuminemia (88%). Endocrine parameters demonstrated no major abnormalities in the functioning of the thyroid and pituitary pars intermedia. The parathyroid hormone concentration was increased in 7 (47%) of 15 horses with an elevated 25-hydroxy vitamin D in 3 (17%) of 17 horses. Main Limitations: The main limitations of this study are the small sample size and lack of age-matched and management-matched control horses. The relevance of elevated parathyroid hormone in this study cannot be determined due to the lack of age-based controls and large population studies. With the small population evaluated in this study, there are no obvious hematological, biochemical, and endocrine changes evident. Further evaluation with signalment-matched controls will be necessary to evaluate some trends noted in the laboratory values.

    Although, the effect of Ramadan fasting on the risks for Cardiovascular Disease (CVD) has been reported in several studies, the results were inconsistent. In addition, the effect of Ramadan fasting on biochemical parameters in Thai subjects has not been evaluated. The aim of this study was to investigate the effect of Ramadan fasting on anthropometry, blood pressure, Fasting Blood Glucose (FBG), lipid profiles, and body composition in healthy Thai subjects. A total of 65 healthy subjects (21 men and 44 women) aged between 19-24 years were randomly recruited. Anthropometry, blood pressure, FBG, Total Cholesterol (TC), Triglyceride (TG), High Density Lipoprotein-Cholesterol (HDL-C), Low Density Lipoprotein-Cholesterol (LDL-C), and body composition were measured before Ramadan, end of Ramadan and after one month of Ramadan. There were no changes in anthropometry, blood pressure, lipid profiles and body composition in both genders before Ramadan, end of Ramadan and after one month of Ramadan. Nevertheless, FBG levels were significantly increased after one month of Ramadan compared with baseline (5.09±0.50 versus 4.83±0.38 mmol/L, p=0.016, respectively) in women. The Ramadan fasting did not affect the lipid, anthropometric and body composition in healthy Thai subjects. However, the increased FBG levels after one month of Ramadan were observed in women. To improve the favourable biochemical parameters after Ramadan fasting, the lifestyle modifications such as, increased intake of healthy diets and increased physical activity should be recommended.

    2015-01-01

    Full Text Available Aspartame (ASP is one of the most widely used nonnutritive sweeteners. This study investigates the chronic effects of ASP on hematological and biochemical parameters, and its effects on the oxidative/antioxidative status in the red blood cells of Wistar albino rats. Rats were provided with ASP (40 mg/kg/daily for six weeks in drinking water. Increased food and fluid intake was observed in the ASP-treated rats. Total body mass was significantly decreased in the ASP-treated rats. Treatment with ASP caused an increase in the concentrations of glucose, cholesterol, LDL-cholesterol, and in the activities of alanine aminotransferase (ALT, aspartate aminotransferase (AST and lactate dehydrogenase (LDH, as well as a decrease in the levels of HDL-cholesterol in the serum. A significant decline in the number of white blood cells (WBC was observed after ASP uptake. Based on the results we conclude that ASP induces oxidative stress, observed as an alteration of the glutathione redox status, which leads to increased concentrations of nitric oxide (NO and lipid peroxides (LPO in the red blood cells. Changes in biochemical parameters, lipid metabolism, as well as changes in the levels of oxidative stress markers and the appearance of signs of liver damage indicate that chronic use of ASP can lead to the development of hyperglycemia, hypercholesterolemia and associated diseases.

    2008-09-01

    Full Text Available Abstract D-ribose, a naturally occurring pentose carbohydrate, has been shown to replenish high- energy phosphates following myocardial ischemia and high intensity, repetitive exercise. Human studies have mainly involved short-term assessment, including potential toxicity. Reports describing adverse effects of D-ribose with prolonged ingestion have been lacking. Therefore, this study assessed the toxicity of extended consumption of D-ribose in healthy adults. Nineteen subjects ingested 20 grams/Day (10 grams, twice a Day of ribose with serial measurements of biochemical and hematological parameters at Days 0, 7, and 14. No significant toxic changes over the 14-day assessment period occurred in complete blood count, albumin, alkaline phosphatase, gamma glutamyltransferase, alanine amiotransferase, and aspartate aminotransferase. However, D-ribose did produce an asymptomatic, mild hypoglycemia of short duration. Uric acid levels increased at Day 7, but decreased to baseline values by Day 14. D-ribose consumption for 14 days appears not to produce significant toxic changes in both hematological and biochemical parameters in healthy human volunteers.

    Liao, Jia-yu; Song, Yang; Liu, Yan

    2015-12-01

    Förster resonance energy transfer (FRET) has been widely used in biological and biomedical research because it can determine molecule or particle interactions within a range of 1-10 nm. The sensitivity and efficiency of FRET strongly depend on the distance between the FRET donor and acceptor. Historically, FRET assays have been used to quantitatively deduce molecular distances. However, another major potential application of the FRET assay has not been fully exploited, that is, the use of FRET signals to quantitatively describe molecular interactive events. In this review, we discuss the use of quantitative FRET assays for the determination of biochemical parameters, such as the protein interaction dissociation constant (K(d)), enzymatic velocity (k(cat)) and K(m). We also describe fluorescent microscopy-based quantitative FRET assays for protein interaction affinity determination in cells as well as fluorimeter-based quantitative FRET assays for protein interaction and enzymatic parameter determination in solution.

    Effect of daily oral doses of 0.9 and 2.5 mg/kg of the carbamate insecticide oxamyl for 16 days on selected hematological and biochemical parameters in male rats was investigated. The weight of animals was significantly decreased compared to controls. The hematological studies revealed significant reduction in red blood cell count, hemoglobin and hematocrit values. Impairment of thyroid function was noticed by elevation of triiodothyronine (T 3 ) and depression of thyroxine (T 4 ). Brain acetylcholinesterase (AchE) was moderately inhibited in the first few days of exposure. However, the results of the parameters investigated indicate a moderate degree of toxicity of oxamyl following oral exposure of the doses selected

    Full Text Available Pulmonary complications and closely related with them systemic functional-biochemical abnormalities are the most common complications of cerebral stroke. The purpose of the work was to research functional-biochemical parameters of respiratory function and to find it’s association with morphological changes in the lungs because of intracerebral hemorrhage. 37 sectional observations in patients who die of intracerebral hemorrhage were analized. It was conducted analysis of morphological transformations and retrospective analysis of functional-biochemical findings of respiratory functions, in order to detect changes of systemic hemodynamics, oxygen balance and ion-osmotic one and acid-alkaline status. The results of the study. The changes of blood gas composition and acid-alkaline status are registered in the lungs in the background of microcirculation disturbance from the first hours of development of intracerebral hemorrhage. During the first days of the onset of disease the partial oxygen pressure in arterial blood (РаО2 decreased 50,88% in comparison with the calculated normative findings. Partial pressure of carbon dioxide (РаСО2 in the arterial blood rosed by 52,17%. Without conducting artificial lung ventilation PO2 in venous blood decreased by 45,9%, and PCO2 increased by 40%. I has been marked a decrease in the oxygen capacity of the blood, due to the reduction of hemoglobin content in the blood to 103,7 minus 2 g/l and the concomitant decline in hematocrit up to 0,24-0,3. Deficit of the foundations has averaged from -6 to -10 mmol/l. These changes have led to a impression of the respiratory and metabolic acidosis, with a significant increase in the concentration of hydrogen ions. In the first day after the development of the disease with a rapid growing marks of swelling of the brain with concomitant dislocation of the brain stem, blood pH was 7,28 minus 0,02. It has been histologically determined interstitial edema, that

    Tea (Camellia Sinensis (L.)) is an important economic crop and the market price of tea depends largely on its quality. This research aims to explore the potential of hyperspectral remote sensing on predicting the concentration of biochemical components, namely total tea polyphenols, as indicators of tea quality at canopy scale. Experiments were carried out for tea plants growing in the field and greenhouse. Partial least squares regression (PLSR), which has proven to be the one of the most successful empirical approach, was performed to establish the relationship between reflectance and biochemical concentration across six tea varieties in the field. Moreover, a novel integrated approach involving successive projections algorithms as band selection method and neural networks was developed and applied to detect the concentration of total tea polyphenols for one tea variety, in order to explore and model complex nonlinearity relationships between independent (wavebands) and dependent (biochemicals) variables. The good prediction accuracies (r2 > 0.8 and relative RMSEP < 10 %) achieved for tea plants using both linear (partial lease squares regress) and nonlinear (artificial neural networks) modelling approaches in this study demonstrates the feasibility of using airborne and spaceborne sensors to cover wide areas of tea plantation for in situ monitoring of tea quality cheaply and rapidly.

    Periodontal diseases in dogs are caused by bacteria colonising the oral cavity. The presence of plaque comprising accumulations of aerobic and anaerobic bacteria leads to the development of periodontitis. Due to the fact that in a large percentage of cases periodontal diseases remain undiagnosed, and consequently untreated, they tend to acquire a chronic character, lead to bacteraemia and negatively impact the health of internal organs. The aim of the present study was to perform a qualitative microbiological analysis of gingival pockets and determine the correlations between selected morphological and biochemical blood parameters and the extent periodontal diseases. Twenty-one dogs treated for periodontal diseases were qualified for the study and subsequently divided into two groups: with 3rd and 4th stage of periodontal disease. Swabs from the patients' gingival pockets were taken for bacteriological testing. Blood was tested for parameters including erythrocyte count, haemoglobin concentration, haematocrit values and leukocyte count. Blood serum was analyzed with respect to the concentrations of alanine transaminase (ALT), aspartate transaminase (AspAT/AST) and urea. The microbiological analysis of gingival pockets indicated the presence of numerous pathogens with a growth tendency in bacterial cultures observed in dogs with advanced-stage periodontal disease. The concentration of biochemical blood markers was significantly higher in dogs with 4th stage of periodontal disease, to compared to the 3rd-stage group. Morphological parameters were not significantly different with the exception of haemoglobin concentration, which was lower in dogs with 4th stage disease. In both groups, elevated leukocyte counts were observed. By conducting a detailed microbiological examination, it is possible to provide a better prognosis, plan adequate treatment and monitor dogs treated for peridontopathy.

    In this study, we evaluated the effects of BDE-99 on hormone homeostasis, as well as in urinary and serum biochemical parameters of adult male rats. Animals (10 per group) received BDE-99 by gavage at single doses of 0, 0.6 and 1.2mg/kg. Forty-five days after BDE-99 exposure, urine and serum samples were collected for hormonal and biochemical analysis. Oxidative stress (OS) markers in erythrocytes, plasma and urine were also evaluated. Urinary excretion of total protein significantly increased following BDE-99 exposure, while lactate dehydrogenase (LDH), gamma-glutamil transferase (GGT), and N-acetylglucosaminidase (NAG) activities significantly decreased. Liver toxicity was evidenced by elevated serum activities of the enzymes glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) and alkaline phosphatase (ALP). Following BDE-99 administration, OS markers in erythrocytes showed an increase in superoxide dismutase (SOD) activity, and a reduction in glutathione reductase (GR) activity. In urine, isoprostane levels increased after BDE-99 exposure. The hormonal analysis showed a significant decrease in testosterone and progesterone levels. These results support the hypothesis that BDE-99 interacts with hormonal response. Moreover, BDE-99 administration to adult male rats showed signs of renal and hepatic toxicity.

    Objective(s) : Fasting during the month of Ramadan is a religious obligation and belief for healthy adult Muslims. The aim of the present study was to determine the effects of Ramadan Fasting and physical activity on 'Blood Hematological-Biochemical Parameters'. In this study, twenty-six healthy males in two experimental groups were compared in two different instances before and after the training period. The groups which were selected by convenience sampling method were divided into two non-active fasting (n=13) and active fasting (n=13) groups. For comparison purposes between groups, paired and independent sample t-test was performed, respectively, after ensuring their normality within a significance level of P≤0.05. HDL-C increased significantly in both active and non-active fasting groups, Moreover, amount of hematocrit (Hct), red blood cell count (RBC), TC, LDL, VLDL, LDL/HDL and TC/ HDL decreased significantly. Amount of hemoglobin (Hgb) and glucose reduced significantly in the active-fasting group. The variation of the means between the groups in the Hgb index and LDL/HDL were statistically significant. Fasting during the month of Ramadan by regular physical activity caused positive alterations in Hematological-Biochemical Index. These changes may be due to the alterations in diet, biology response of the body to the starving and physical activity during this month.

    Full Text Available Aim: In Sultanate of Oman, goats are considered as one of the most important livestock in which there are many breeds of goat such as Batinah, Jabali, Dhofari, Jabal Al-Akhdar, Sahrawi, and Sahrawi Musandam. Little hematological and biochemical information is known on Omani goat breeds; therefore, the main purpose of this study was to determine reference baseline data regarding hematological and biochemical values of different Omani goat breeds. Materials and Methods: A total of 30 healthy animals of different Omani goat breeds (Jabali, Jabal Al-Akhdar, Sahrawi, and Sahrawi Musandam were selected randomly from different areas in Sultanate of Oman. The blood samples were collected from the jugular vein into two tubes for blood hematology and biochemical analysis. Statistical analysis was applied by using GraphPad Prism 7 software to calculate the minimum and maximum values to determine the range, mean, standard deviation of the mean and the p value. Results: No statistically significant variation in most hematological and biochemical parameters was found among the Omani goat breeds. The results of blood hematology revealed that the mean white blood cells (14.6±3.32 x103/μL, and the percentage of neutrophils in Omani goats (60.87±8.46% were higher than that in most goat breeds. Higher values of red blood cells (12.8±1.28 x106/μL, hemoglobin (10.4±1.92 g/dl, hematocrit (38.29±4.06%, and lower values of mean corpuscular HGB concentration (27.05±3.5 g/dl were observed in Omani goat breeds comparing to that in the other goat breeds. Lower values of total bilirubin (0.22±0.03 mg/dl, blood urea nitrogen (14.62±2.66 mg/dl, and cholesterol (48.58±19.05 mg/dl were found in Omani goat breeds when compared to that of the other goat breeds. Conclusion: The obtained results are considered as the first values to be published for the different Omani goat breeds. This study is considered as preliminary study which can be used as a reference for further

    The effects of pregnancy on some biochemical parameters were studied using 20 sexually mature, cycling goats with weight range 20-25 kg. They were randomly separated into two groups of 10 animals each. In one group, oestrus was detected while going round with a buck in the morning and evening; a single buck on detection of oestrus mated the does and the does were tagged as pregnant after confirmation of non-return of oestrus. The other group was kept cycling and tagged as non-pregnant. The mean serum glucose concentration in pregnant does was 63.35 +/- 7.70 mg/dl, significantly lower than 71.59 +/- 1.14 mg/dl for non-pregnant does (p 0.05), as did the liver enzymes (ALT, AST). Therefore this study showed that low serum glucose and high cholesterol levels are features of mid to late pregnancy in Sahel goats.

    Full Text Available This paper presents the results of some biochemical parameters obtained in the laboratory of “Elena Beldiman” Emergency Hospital Barlad, and in the”Dr. Stoian –Dr. Ungureanu”Private Medical Practice on 10 patients diagnosed with multiple myeloma during 2005-2011. Numerous researches over serum proteins with the help of various methods ( refractometry have shown the presence of some changes in protein fractions of blood serum. These changes express the change of the normal ratio between these fractions, that means disorders in colloidal structure of blood. The results of the electrophoresis analysis, also in accordance with those from the scholarly literature, show that the changes in the condition of the blood serum are due to the increase in the globulins fractions which is linked to the growth of the immunological processes, the antibodies synthesis being especially closely linked to gammaglobulinic fraction

    This study evaluated the effects of diets containing 0, 2.5, 5, 7.5 and 10% of Spirulina platensis on hematological and serum biochemical parameters of rainbow trout (Oncorhynchus mykiss). Fish (n=180; 101±8 g) were randomly divided into fifteen 300 L fiberglass tanks in triplicates for a period of ten weeks. The RBC, WBC, hemoglobin, total protein and albumin levels increased significantly in the groups supplemented with S. platensis. Dietary inclusion of S. platensis had no significant effects on hematocrit, cholesterol, triglyceride and lactate of the blood. HDL-cholesterol was larger in rainbow trout fed 10% S. platensis in comparison with the other diets, whereas LDL-cholesterol significantly decreased with increasing of S. platensis inclusion. Cortisol and glucose significantly decreased with increasing of S. platensis inclusion. The present results demonstrate that inclusion of 10% S. platensis can be introduced as an immunostimulant in rainbow trout diets. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available This study aimed to investigate the effects of n-hexane, chloroform, ethyl acetate, n-butanol and aqueous fractions of the methanolic extract of Melia azedarach fruits on serum glucose, lipid profile, GPT, ALP and creatinine of normal rabbits. Each fraction at a dose of 50 mg/kg body weight was orally administered to normal rabbits for 40 days and the serum biochemical parameters were estimated on days 20 and 40 after treatment. All of the extracts significantly decreased serum glucose, cholesterol, triglycerides and LDL concentrations, however, their administration caused elevation of serum HDL levels. All except the aqueous extract, caused a significant rise in the serum levels of GPT, ALP and creatinine. The present study demonstrates that all of the extracts possess hypoglycemic, hypolipidemic and HDL boosting properties. Of the tested extracts, only the aqueous fraction was found safe, as it caused no significant alterations in the serum levels of GPT, ALP and creatinine.

    Full Text Available Objective This study investigated the effect of fermented biogas residue (FBR of wheat on the performance, serum biochemical parameters, and meat quality in pigs. Methods We selected 128 pigs (the mean initial body weight was 40.24±3.08 kg and randomly allocated them to 4 groups (1 control group and 3 treatment groups with 4 replicates per group and 8 pigs per pen in a randomized complete block design based on initial body weight and sex. The control group received a corn-soybean meal-based diet, the treatment group fed diets containing 5%, 10%, and 15% FBR, respectively (abbreviated as FBR5, FBR10, and FBR15, respectively. Every group received equivalent-energy and nitrogen diets. The test lasted 60 days and was divided into early and late stages. Blood and carcass samples were obtained on 60 d. Meat quality was collected from two pigs per pen. Results During the late stage, the average daily feed intake and average daily gain of the treatment groups was greater than that of the control group (p<0.05. During the entire experiment, the average daily gain of the treatment groups was higher than that of the control group (p<0.05. Fermented biomass residue did not significantly affect serum biochemical parameters or meat quality, but did affect amino acid profiles in pork. The contents of Asp, Arg, Tyr, Phe, Leu, Thr, Ser, Lys, Pro, Ala, essential amino acids, non-essential amino acids, and total amino acids in pork of FBR5 and FBR10 were greater than those of the control group (p<0.05. Conclusion These combined results suggest that feeding FBR could increase the average daily gain and average daily feed intake in pigs and the content of several flavor-promoting amino acids.

    Full Text Available ABSTRACT The aim of this study was to evaluate the effects of forced molting using biochemical parameters and histopathological findings in laying hens. 36 Hyline W36 strain laying hens, 90 weeks old were chosen for this research. Eight of these chickens were randomly selected and placed in a cage as the control group before the molting program began. All the others 28 chickens were used for the forced molting program. Eight laying hens were slaughtered at the end of the molting program named as molting group. The remaining 20 hens were fed for 37 days, weighted and slaughtered when they reached the maximum egg production (80% as postmolting group. Then, blood was analyzed for malondialdehyde, glutathione, catalase, glucose, calcium, phosphorus, albumin, globulin, total protein, triiodothyronine, thyroxine and Vitamin C. The malondialdehyde and glutathione levels of the thyroid and liver tissues were also analyzed along with an examination of the histopathological changes of the liver, ovarium and thyroid glands; and live body, liver, ovarium, thyroid weights and thyroid lengths. In conclusion, it was found that forced molting produces stress and notable side effects in hens, like the oxidant and antioxidant status of the organs, tissue weights and sizes, hormon profiles, blood biochemical and histopathological parameter changes. The activities of thyroid malondialdehyde (p<0.05, liver glutathione (p<0.01, plasma catalase (p<0.001 were significantly decreased in molting group compared to control values, while liver malondialdehyde levels were significantly increased (p<0.001 and thyroid glutathione levels had nonsignificant effect. These levels in molting hens were the first study for veterinary science.

    Hypertensive crisis is a common clinical situation that presents a high rate of morbidity and mortality and it is characterized by symptomatic rise of blood pressure (BP), systolic (SBP) ≥ 180 mmHg and/or diastolic (DBP) ≥ 120 mmHg. It is classified as emergency (HE) or hypertensive urgency (HU). There is no description of laboratory findings in patients who present acute BP elevation. Thus, this study had the objective to assess the biochemical-metabolic parameters of patients with HC. We studied 74 normotensive individuals (NT), 74 controlled hypertensive patients (ContrHT), 50 subjects with HU, and 78 with HE for evaluating biochemical-metabolic parameters. HE occurs in older individuals and more frequently in those with known hypertension. More patients with HE had dyslipidemia than those with HU (58% vs. 38%). The diastolic BP and heart rate were higher in the HE group (120 mmHg and 87 bpm) compared to ContrHT (71 mmHg and 71 bpm; p hypertensive crisis ContrHT = controlled hypertensive DBP = diastolic blood pressure GFR = glomerular filtration rate HbA1c = glycated hemoglobin HDLc = high-density lipoprotein cholesterol HE = hypertensive emergency HPLC = high-performance liquid chromatography HR = heart rate HU = hypertensive urgency JNC 7 = VII Joint National Committee on the Detection, Evaluation, and Treatment of High Blood Pressure LDLc = low-density lipoprotein cholesterol MDRD = Modification of Diet in Renal Disease NT = normotensive RASB = renin-angiotensin system blockers SBP = systolic blood pressure TC = total cholesterol TG = triglycerides.

    Full Text Available From a complex experiment of establishing the effects of lecithin supplemented in the diet of small ruminants, in this paper we present the influence of lecithin on some sanguine biochemical parameters at lactating sheep and goat. The researches were made on a experimental group formed by 5 sheep from łurcana breed and 5 goats from Crapatina breed, which were fed in the first experimental period with a base ratio (Br formed by 1.5 kg of hill hay and 0.2 kg concentrate forage mixture, in the second experimental period the Br was supplemented with 100 g lecithin/day/animal. At the end of each experimental period were taken blood samples to establish some biochemical parameters from sanguine serum. The supplementation of base ration with 100 g lecithin/day/animal at lactating sheep and goats did not produced significant changes to values of total proteins (TS, albumin, creatinine, urea and total bilirubins (TB from sanguine serum. Contrary to expectation the cholesterol and triglycerides were higher than normal both in sheep (from 82 mg/dl to 83 mg/dl for cholesterol and from 23 mg/dl to 45 mg/dl for triglycerides but specially in goats (from 59 mg/dl to 68 mg/dl for cholesterol and from 24 mg/dl to 55 mg/dl for triglycerides. Were registered significant increment of activity of alkaline phosphatase and in γ – GT and a decrease of plasmatic activity of pancreatic α-amylase both in sheep and goats.

    Predictors of quantitative evaluation of hepatic steatosis and liver fat content (LFC) using clinical and laboratory variables available in the general practice in the obese children are poorly identified. To build predictive models of hepatic steatosis and LFC in obese children based on biochemical parameters and anthropometry. Hepatic steatosis and LFC were determined using proton magnetic resonance spectroscopy in 171 obese children aged 5.5-18.0 years. Routine clinical and laboratory parameters were also measured in all subjects. Group analysis, univariable correlation analysis, and multivariate logistic and linear regression analysis were used to develop a liver fat score to identify hepatic steatosis and a liver fat equation to predict LFC in each subject. The predictive model of hepatic steatosis in our participants based on waist circumference and alanine aminotransferase had an area under the receiver operating characteristic curve of 0.959 (95% confidence interval: 0.927-0.990). The optimal cut-off value of 0.525 for determining hepatic steatosis had sensitivity of 93% and specificity of 90%. A liver fat equation was also developed based on the same parameters of hepatic steatosis liver fat score, which would be used to calculate the LFC in each individual. The liver fat score and liver fat equation, consisting of routinely available variables, may help paediatricians to accurately determine hepatic steatosis and LFC in clinical practice, but external validation is needed before it can be employed for this purpose. © 2014 The Authors.

    The objective of the study was to determine whether levels of biochemical and haematological parameters in patients with eating disorders (EDs) varied from the general population. Whilst dietary restrictions can lead to nutritional deficiencies, specific abnormalities may be relevant to the diagnosis, pathogenesis and treatment of EDs. With ethics approval and informed consent, a retrospective chart audit was conducted of 113 patients with EDs at a general practice in Brisbane, Australia. This was analysed first as a total group (TG) and then in 4 ED subgroups: Anorexia nervosa (AN), Bulimia nervosa (BN), ED Not Otherwise Specified (EDNOS), and AN/BN. Eighteen parameters were assessed at or near first presentation: cholesterol, folate, vitamin B12, magnesium, manganese, zinc, calcium, potassium, urate, sodium, albumin, phosphate, ferritin, vitamin D, white cell count, neutrophils, red cell count and platelets. Results were analysed using IBM SPSS 21 and Microsoft Excel 2013 by two-tailed, one-sample t-tests (TG and 4 subgroups) and chi-square tests (TG only) and compared to the population mean standards. Results for the TG and each subgroup individually were then compared with the known reference interval (RI). For the total sample, t-tests showed significant differences for all parameters ( p  data would support routine measurement of a full blood count and electrolytes, phosphate, magnesium, liver function tests, ferritin, vitamin B12, red cell folate, vitamin D, manganese and zinc for all patients at first presentation with an ED.

    Recurrent acute and life-threatening metabolic decompensations are thought to be the major cause of mortality and morbidity in patients with propionic acidemia (PA). Since metabolic decompensations in these patients usually develop gradually, there is considerable uncertainty about the beginning and when emergency treatment should be initiated. The major aim of this study was to evaluate the usefulness of biochemical parameters for improving decision-making on the start of emergency treatment. We analysed data of 16 PA patients continuously followed in our centre. Metabolic decompensation was defined clinically by the occurrence of at least one of three alarming symptoms: vomiting, food refusal or impaired consciousness. Thirty-eight biochemical parameters were analysed. A total of 259 metabolic decompensations were documented and compared with 625 routine visits. Among the symptoms used to clinically define metabolic decompensations, vomiting was most frequent (87 %). In total, 19 biochemical parameters differentiated between metabolic decompensations and routine visits. Among them ammonia, acid-base balance and anion gap were most reliable to identify a metabolic decompensation, and to estimate its severity. A comparative analysis of patients with PA and methylmalonic acidemia during metabolic decompensation showed similar results. Ammonia, acid-base balance and anion gap are important biochemical parameters to identify an (impending) metabolic decompensation and to assess its severity in PA patients. The identified biochemical parameters should be integrated in an algorithm for clinical decision-making on emergency treatment and should be tested in a prospective trial.

    Consumption of green banana flour (GBF) may promote health benefits, such as, decreased appetite, weight loss, glycemic control, intestinal function and lipid profile improvement, aging delay, cancer and heart disease prevention. The aim of this study was to evaluate the effects of green banana flour consumption on anthropometric and biochemical parameters in overweight women. The glycemic index of flour in the study was determined. The effects of consumption of 20 g of green banana flour/day on weight, body mass index (BMI), blood pressure, waist and hip circumference, body composition, hemoglobin, lipid profile, glucose, insulin, insulin resistance, liver function and energy intake were evaluated in 25 overweight women for 45 days. The glycemic index of the flour under study was classified as low. Reduction (p blood pressure, hip circumference and fasting glucose levels were found in women who had metabolic syndrome criteria. Consumption of green banana flour (20 g/day) for 45 days did not promote weight loss or changes in body composition in overweight women. It was noted, however, decreased hip circumference. Significant health parameter improvements were also noted in individuals with metabolic syndrome, which showed a reduction in systolic blood pressure and fasting glucose.

    The present study was designed to investigate the effect of exposure to pulsed electromagnetic spectrum on some biochemical and hematological parameters in female albino rats. A group of mature female rats was exposed to 10 pulses of electromagnetic spectrum (frequency 8-12 GHz) 3 times/week for 3 weeks. The untreated group was considered as the control group. At the end of the experiment, serum levels of malondialdehyde, thyroid triiodothyronine and thyroxine (T3, T4), α-feto protein, estradiol, calcium, urea, creatinine and other hematological parameters were estimated. The present data revealed that serum levels of estradiol, malondialdehyde, urea, creatinine, triiodothyronine and thyroxine were elevated in the exposed group while serum calcium was significantly decreased. Non-significant difference was found in the value of α-feto protein between the two groups. The hematological studies revealed that exposure of rats to electromagnetic spectrum induced significant reduction in red blood cells (RBCs), hemoglobin concentration (Hb) and in hematocrit percent (Hct%), while reticulocyte count (Ret %) was elevated in the treated group. Non-significant changes were observed in platelets, leukocyte (WBCs) and lymphocytic counts in the exposed group as compared to the control group

    Biochemical methane potential (BMP) test is a key analytical technique to assess the implementation and optimisation of anaerobic biotechnologies. However, this technique is characterised by long testing times (from 20 to >100days), which is not suitable for waste utilities, consulting companies or plants operators whose decision-making processes cannot be held for such a long time. This study develops a statistically robust mathematical strategy using sensitivity functions for early prediction of BMP first-order model parameters, i.e. methane yield (B 0 ) and kinetic constant rate (k). The minimum testing time for early parameter estimation showed a potential correlation with the k value, where (i) slowly biodegradable substrates (k≤0.1d -1 ) have a minimum testing times of ≥15days, (ii) moderately biodegradable substrates (0.1

    Full Text Available The effect of oral administration of iron on haematological, biochemical and immunological parameters in neonatal calves was studied. Ten calves from a private farm in Gharbia Governorate were used. Calves were separated from their dams immediately after birth and received colostrum during the first hours after calving and twice daily for 48 h. Thereafter, they received whole milk. Calves were divided into two equal groups. The first group was kept as controls. Calves of the second group were given ferrous sulphate at a dose of 250 mg/calf daily, beginning at one day of age; this was continued for 28 days. Three blood samples were collected from each calf in all groups at 14, 21, 28 and 35 days of age. Iron administration produced a significant increase in red blood cell count, haemoglobin, packed cell volume and blood indices, in addition to non-significant changes in total and differential leukocyte counts. The administration of iron resulted in a significant increase in serum iron, total proteins, globulins, thyroid hormones, lymphocyte stimulation index, phagocytosis, body weight and body gain. The administration of iron is suggested as routine practice in calf-producing farms due to its advantageous effects on the parameters tested.

The study is carried out with 10 women: 5 premenopausal and 5 postmenopausal women. The serum Li levels, bone metabolism indicators (i.e., ALP, Ca, P, Mg, Cu, Zn and some biochemical parameters such as serum tryglyceride, alkalene phosphatase, total cholesterol, HDL, LDL and cholesterol levels were determined. The estrogen blood level of women in menopause period was found to be lower than that of women in pre-menopause period (p<0.01 and the FSH level was found to be higher (p<0.01. In the lipid profile the triglyceride level in the post-menopause period was found to be low (p<0.05 and HDL (p<0.001, LDL (p<0.001 and the cholesterol levels were found to be high (p<0.001. The alkalene phosphatase (p<0.001 and Vitamin-D levels (p<0.001 were found to decrease. When the mineral levels were investigated no meaningful difference was observed in the serum magnesium and copper levels while zinc (p<0.01 and phosphorus (p<0.005 levels were observed to increase, the calcium levels (p<0.05 decreased and Li levels considerably decreased (p<0.0001. According to the results obtained it was determined for the first time that Li defficiency can be related with menopause and the related diseases and thus Li therapy can be used in developing new treatment protocols of menopause as an alternative method.

    Background, aim, and scope Restoration of lakes and reservoirs with extensive cyanobacterial water bloom often requires evaluation of the sediment quality. Next to the chemical analysis of known pollutants, sediment bioassays should be employed to assess toxicity of the present contaminants and to make predictions of associated risk. Brno reservoir in the Czech Republic is a typical example of water bodies with long-term problems concerning cyanobacterial water blooms. Comprehensive assessment of reservoir sediment quality was conducted since successful reservoir restoration might require sediment removal. An important part of this survey focused on an examination of the utility of Tubifex tubifex and its sublethal biochemical markers for the assessment of direct sediment toxicity. Materials and methods This complex study included chemical analysis of contaminants (heavy metals, organic pollutants), ecotoxicity testing of sediment elutriates (tests with Daphnia magna, Pseudomonas putida, Sinapis alba, Scenedesmus subspicatus), and other parameters. We have tested in more detail the applicability of T. tubifex as a test organism for direct evaluation of contact sediment toxicity. Survival tests after 14 days of exposure were complemented by an assessment of parameters serving as biomarkers for sublethal effects [such as total glutathione content (GSH), activities of the enzymes glutathione transferase (GST), glutathione peroxidase (GPx), and glutathione reductase (GR)]. The data matrix was subjected to multivariate analysis to interpret relationships between different parameters and possible differences among locations. Results The multivariate statistical techniques helped to clearly identify the more contaminated upstream sites and separate them from the less contaminated and reference samples. The data document closer relationships of the detected sediment contamination with results of direct sediment exposure in the T. tubifex test regarding mortality but namely

    Full Text Available ABSTRACT: The purpose of this study was to assess the levels of available phosphorus (AP in the diet of growing pigs selected for lean deposition on the hematological, biochemical, and bone performance parameters. A total of 64 commercial hybrid pigs (32 castrated males and 32 females; mean initial weight: 23.31±2.4kg; age: 55-90 days were used. Animals were distributed into a randomized block design with four treatments, eight replicates, and two animals (one male and one female per experimental unit. The treatments consisted of a basal diet and another three diets, which were obtained by supplementing the basal diet with dicalcium phosphate replacing the inert phosphate, resulting in four diets with 0.100, 0.180, 0.260, and 0.340% of available phosphorus. The levels of available phosphorus quadratically influenced the daily weight gain, feed consumption, and feed conversion, which increased up to the estimated levels 0.331; 0.330, and 0.302% of available phosphorus. Levels of phosphorus showed no influence on the hematological parameters, which remained within the reference values. Levels of available phosphorus increased linearly the ash and phosphorus contents in the metacarpal bone and decreased linearly the alkaline phosphatase activity. Levels of available phosphorus (0.331 and 0.302%, corresponding to a daily intake of 5.73 and 5.18g d-1 provided respectively the best results for weight gain and feed conversion in pigs with high genetic potential, without change in hematological parameters.

    Full Text Available Aim: In this study, sub-acute toxicity of deltamethrin on hematological and biochemical blood parameters of male albino Swiss mice was evaluated. Materials and Methods: Generally, the maximum permissible residue level (MRL of deltamethrin for food products lies between 0.01 to 0.5 mg/kg body weight. So the mice were exposed orally with two doses of pesticide i.e. 0.1 and 0.5 mg/kg body weight. The doses were given on a daily basis for a period of 15 days and 30 days respectively. Ground nut oil was used as control treatment. Samples of blood were collected at the end of the treatment. Hepatotoxicity was evaluated by quantitative analysis of the serum enzymes alanine transaminase (ALT, aspartate transaminase (AST, alkaline phosphatase (ALKP, total bilirubin (TBIL and serum urea. Alterations of hematological parameters were analysed by total leukocyte, differential leukocyte count and hemoglobin levels. Results: Significant increase in the levels of hepatic enzymes (ALT, AST, ALKP were observed for both doses, but no considerable differences were found by histological analysis. The hematological parameters showed significant alterations for 0.5 mg/kg body weight dose which is indicated by leukocytosis, lymphocytosis and neutropenia in long duration study. Conclusions: The results indicated that even very low dose of deltamethrin can promote hematological and hepatic alterations. Thus it is imperative to do further studies on the detrimental effect of the low levels of pyrethroid commonly present in our food, which further necessitate the reduction of maximum permissible levels of residual synthetic pyrethroid levels in foods and feed.

    Cefpodoxime is a semisynthetic third generation cephalosporin analogue with a relatively broader spectrum of antimicrobial activity against gram negative and gram positive organisms. This is attributed to their somewhat increased resistance to degradation by the betalactamase. Cefpodoxime shows good activity against Klebsiella pneumonia, many members of enterobactericeae and almost all strains of Escherichia coli. It is extensively used in human beings against infections caused by susceptible organisms for a prolonged period and even without its judicious indication. Though various researchers have worked on the pharmacokinetic aspects of the drug, its effects on biochemical parameters and spermatozoa activity are scarcely available in literature. To determine the oral kinetic ( blood and tissue) after single therapeutic dose of cefpodoxime proxetil (20mg/kg oral bid 7 days) in rats of either sex on tissue half life and certain biochemical parameters such as glucose, hemoglobin, protein, ALT, AST and other parameters like tissue residue, sperm count and spermatozoa motility in male rats. For kinetic studies,24 Wister rats of either sex, 3 months of age, (180-210 gm) were used.(Group I-IV; n=6) Blood samples collected from each animal of Group IV through heart puncture at 0 hour to serve as predrug control. All the group (I-IV) received cefpodoxime proxetil 20 mg/kg once orally as a single dose. At the end of 1,4,12 and 24 hour post oral administration, GroupI,II,III and IVwere utilized for kinetic studies. Blood samples were collected from each animal and vital organs viz brain, lung, liver, spleen, kidney and heart were dissected out for drug analysis and determination of weight. For biochemical parameters, tissue residue and spermatozoa motility, twelve male rats were randomly divided into Groups A and B (n=6) Group B received cefpodoxime (20mg/kg orally bid 7 days) while Group A served as control.

    Dermatophilosis is one of the major economically important diseases of cattle in Nigeria. Managing the condition has been very challenging and re-occurrence has been reported with moderate to high morbidity and mortality. The incidence and biochemical features of cattle with dermatophilosis was conducted in June to December 2016 across the four geopolitical zones of Oyo state, Nigeria. Clinical diagnosis were made based on appearance of dermatophilosis lesion, breeds morphologically characterized, ageing were based on rostral dentition and severity based on the extent and nature of the lesion. Biochemical analysis was based on standard procedure as prescribed by Fortress International. Fifty cattle were found to be infected with clinical dermatophilosis during the period of the study. Twenty four (48%) in Ibadan zone, 14 (28%) in Oyo/Ogbomosho, 8 (16%) in Oke-ogun and 4 (8%) in Ibarapa zone. Breeds distribution across the zones showed 28 (56%) White Fulani, 5 (10%) Sokoto Gudali, 3 (6%) Adamawa Gudali, 7 (14%) Red Bororo, 5 (10%) Cross breeds while the Kuri was 2 (4%). Regarding animal ages, less than 2 years old were 2 animals (4%) while the adults were 48 animals (96%) and they fall under the categories of 2-2½ years of age, 3-3½ years of age and those which are over 3½ years of age. The different levels of severity were categorized into mild (20 (40%)), moderate (23 (46%)) and severe (7 (14%)) .The best parameters were seen in White Fulani, while the least were seen in Adamawa Gudali. The age group in the category of 3 - 3½ years had most of the best serum values while the least values were seen in animals less than 2 years of age. Cattle exhibiting mild lesions had most of the best serum values and the least values were observed in cattle with severe lesions. No significant difference (p > 0.05) was observed in the mean values for the various parameters studied among the breeds, age, and severity of condition.

    Tuberculosis (TB) remains a major public health issue due to the increasing incidence of type 2 diabetes mellitus (T2DM), which exacerbates the clinical course of TB and increases the risk of poor long-term outcomes. The aim of this study was to characterize the pharmacokinetics of rifampin (RIF) and its relationship with biochemical and immunological parameters in patients with TB and T2DM. The biochemical and immunological parameters were assessed on the same day that the pharmacokinetic evaluation of RIF was performed. Factors related to the metabolic syndrome that is characteristic of T2DM patients were not detected in the TB-T2DM group (where predominant malnutrition was present) or in the TB group. Percentages of CD8(+) T lymphocytes and NK cells were diminished in the TB and TB-T2DM patients, who had high tumor necrosis factor alpha (TNF-α) and low interleukin-17 (IL-17) levels compared to healthy volunteers. Delayed RIF absorption was observed in the TB and TB-T2DM patients; absorption was poor and slower in the latter group due to poor glycemic control. RIF clearance was also slower in the diabetic patients, thereby prolonging the mean residence time of RIF. There was a significant association between glycemic control, increased TNF-α serum concentrations, and RIF pharmacokinetics in the TB-T2DM patients. These altered metabolic and immune conditions may be factors to be considered in anti-TB therapy management when TB and T2DM are concurrently present.

    Full Text Available Aim: The aim of the present study was the evaluation of non-microbial salivary caries activity parameters and salivary biochemical indicators in predicting dental caries. Materials and Methods: The present study was carried out on 60 children, aged 4-6 years, selected from the schools of Panchkula district, Haryana, on the basis of their caries status. Level of hydration, flow rate, pH, buffering capacity, relative viscosity, calcium, phosphorus and alkaline phosphatase levels in caries-free and caries-active children were evaluated. Results: Results showed that 90% of subjects in the caries-free group and 30% of subjects in the caries-active group had normal level of hydration value of less than 60 s and the difference was found to be statistically very highly significant. Normal flow rate of stimulated saliva was found in 90% of the subjects in caries-free group and 33.3% subjects in the caries active group and difference was found to be statistically very highly significant. Adequate salivary pH was found in 100% subjects in caries-free group and 30% in caries-active group and the difference was statistically very highly significant. Conclusion: To conclude, within limitations of this study, it became clear that normal level of hydration and higher values for flow rate, pH, buffering capacity of saliva lead to good oral health and a reduced caries occurrence. Increased salivary viscosity plays a role in increasing caries incidence. Salivary biochemical indicators like calcium, phosphorus and alkaline phosphatase also play their respective role in determining caries susceptibility of an individual. These salivary parameters can be used as diagnostic tool for caries risk assessment.

    Wheat germ oil is an organic nutritionally rich vegetable oil. It is an excellent source of vitamin E and essential fatty acids (octacosanol, linoleic and linolenic). The study confirmed the beneficial role of the used anti-oxidation agents as recommended radio-protectors due to their ability of scavenging free radicals produced by ionizing radiation. The efficacy of daily oral treatment of rats with wheat germ oil (10 mg/ Kg body wt) for 15 days to control many of the damaging effects of ionizing radiation when male rats were subjected to fractionated 8 Gy (2 Gy day after day) of gamma irradiation were studied. Blood samples were collected from animals at 10 and 15 days after treatment and/or exposure. In blood, the data obtained revealed that, radiation exposure caused significant increases in levels of malondialdehyde (MDA), triacylglycerol (TG), total cholesterol (TC), low-density lipoproteins (LDL) and glucose at the 10th day. Meanwhile, significant reduction in contents of total protein, albumin, globulins, high-density lipoproteins (HDL), vitamin E and glucose were recorded at the 15th day. Also, the majority of these parameters were estimated in liver tissues. The results revealed that administration of the natural product wheat germ oil partially ameliorated the radiation-induced biochemical disturbances. These effects were explained in the light of the presumed different mechanisms of wheat germ oil actions

    Banana (Musa paradisiaca L.) popularly known as kadali (S) belongs to the family Musaceae is an economically important plant due to its nutritive fruit used as staple food all over the world. Several techniques have been employed to delay fruit ripening and softening by storing preclimacteric bananas in modified or controlled atmospheres. The Food and Drug Administration (FDA) has recommended the usage up to 1.0 kGy of gamma irradiation for delaying the ripening in fruits. Irradiation significantly improved shelf life by inhibiting the fungal growth in strawberries. Hence, present work was undertaken to scrutinize the impact of gamma irradiation on the ripening, storage and the biochemical attributes of Musa paradisiaca L. variety kadali. Present work revealed that irradiation at 0.2 kGy and 0.3 kGy retained their organoleptic properties till 16th day of storage against under normal conditions. Nutritional parameters such as ascorbic acid content, soluble sugar and protein contents were significantly higher in irradiated fruits. Hence, lower dose of gamma irradiation could be successfully used in extending the shelf life and nutritional quality and delay the process of ripening in Musa paradisiaca L.

    2014-09-01

    Full Text Available Triplicate groups of fed and starved olive flounder, Paralichthys olivaceus (body weight: 119.8±17.46 g, were examined over 42 days for physiological changes using hematological, biochemical, and non-specific immune parameters. No significant differences in concentrations of blood hemoglobin and hematocrit and plasma levels of total cholesterol, aspartate aminotransferase, alanine aminotransferase, glucose, and cortisol were detected between fed and starved groups at any sampling time throughout the experiment. In contrast, plasma total protein concentrations were significantly lower in starved fish than in fed fish from day 7 onwards. Moreover, plasma lysozyme concentrations were significantly higher in starved flounder from day 21 onwards. This result confirms that the response of olive flounder to short-term (less than about 1.5 months starvation consists of a readjustment of metabolism rather than the activation of an alarm-stress response. The present results indicate that starvation does not significantly compromise the health status of fish despite food limitation.

    This paper reports on the concept, fabrication and characterization of a multi-chip module microlaboratory. The application is in the spectrophotometric analysis of human physiological fluids in a clinical setting. The system is composed of three stacked parts: (1) a central microfluidic system die containing the microchannels, which is fabricated by applying MEMS techniques to an SU-8 layer, (2) an optical filtering system on the top side, fabricated using a dielectric thin-films multilayer and (3) a detection and readout system on the bottom side, which is fabricated in a CMOS microelectronic process. The system modularity and emphasis on microfabrication provides potential for low unit cost. The application is the simultaneous and quantitative measurement of the concentration of four biochemical parameters in human physiological fluids by spectrally selective optical absorption. The intensity of the light transmitted through the physiological fluid results in an electrical output signal in the form of bit streams, which allows simple computer interfacing. A simple white light source is used for illumination, due to the optical filtering system, which makes the microlaboratory portable. The quantitative measurement of chloride, creatinine, total protein and uric acid in urine is successfully demonstrated.

    Full Text Available The aim of this study was conducted to evaluate the effect of Gundelia tournefortii on some biochemical parameters in hyperglycemic and hyperlipidemic mice. Male albino mice were induced hyperglycemic and hyperlipidemic by daily injection of dexamethasone 1 mg/kg of body weight intramuscularly (i.m., the mice randomly divided into five groups (6-8 mice in each group. The group 1: served as negative control group; the group 2: injected with dexamethasone at dose 1 mg /kg.b.w.i.m and served as positive control group; the groups 3, 4, 5: treated with extract of G. tournefortii at doses: 75, 150, 300 mg/kg.b.w. orally respectively companied with injection of dexamethasone 1 mg/kg.b.w.i.m. All treatment were once daily for 22 days. Dexamethasone treatment lead to significant increase in levels of glucose, cholesterol, and triglyceride, and significant decrease of body weight, without any effect on level of total protein. G. tournefortii extract treatment at doses: 75 mg/kg.b.w. resulted significant decrease levels of glucose, and body weight. Beneficial effect were seen when mice treated with G. tournefortii at dose of 300 mg/kg.b.w. that lead to significant decrease in levels of glucose, triglyceride, and cholesterol. These results indicate the usefulness of G. tournefortii extract as hypoglycemia and hypolipidemia in dexamethasone treated mice.

    Major depression is a heterogeneous psychiatric disorder whose pathophysiology is not clearly established yet. Some studies have shown that oxidative stress and mitochondrial dysfunction are involved in the development of major depression. Since most depressed patients do not achieve complete remission of symptoms, new therapeutic alternatives are needed and omega-3 has been highlighted in this scenario. Therefore, we have investigated the effects of omega-3 on behavioral and biochemical parameters in rats submitted to chronic mild stress (CMS). Male Wistar rats were submitted to CMS for 40 days. After the CMS period, we administered a 500 mg/kg dose of omega-3 orally, once a day, for 7 days. The animals submitted to CMS presented anhedonia, had no significant weight gain, presented increased levels of lipid peroxidation and protein carbonylation, and inhibition of complex I and IV activities of the mitochondrial respiratory chain. The treatment with omega-3 did not reverse anhedonia; however, it reversed weight change, increased lipid peroxidation and protein carbonylation levels, and partially reversed the inhibition of mitochondrial respiratory chain complexes. The findings support studies that state that major depression is associated with mitochondrial dysfunction and oxidative stress, and that omega-3 supplementation could reverse some of these changes, probably due to its antioxidant properties.

    Full Text Available Objective. A 42-days feeding trial was carried out to evaluate the influences of differently thermal processed soybean meal on the broilers blood biochemical parameters. Materials and methods. A total of 200 male birds of Ross strain were allocated into five different diets formulated using differently heat-treated soybean meals, with ten birds per treatment and per replicate. Diets contained: raw soybean (controls, autoclaved for a short (121°C, 20 min; Aut1 group or medium length period (121°C, 30 min; Aut2 group soybean meal, micro-waved soybean meal (46°C, 540 Watt, 7 min; McW group and browned soybean meal (120°C, 20 min; Brn group. Results. Blood serum metabolites showed that all treated diets presented lower lipid metabolism makers and higher protein metabolism markers. Broilers showed increased final body weight when fed heat-treated meals compared with control. Results suggested that thermal treatments altered the lipid metabolism in broilers that might originate a decrease in abdominal fat deposition. Conclusions. Comparison of the results for all the treated groups showed the Aut2 treatment is the most suitable method for soybean thermal treatment processing; in contrast, the Aut1 treatment had the closest results to the control group.

    The aim of this study was to compare biochemical parameters of cultured rainbow trouts (Oncorhynchus mykiss, Walbaum, 1972) reared in two different trout farms' (Agri and Erzurum). The average weights of fish were 150±10gr for first station (Agri), 230±10gr for second station (Erzurum). Fishes used in research were randomly caught from pools, and fifteen pieces were used for each group. Fishes were fed with commercial trout feed with 45-50% crude protein twice a day. The levels of AST, ALT, LDL, total cholesterol and triglyceride in the second station (Erzurum) were found to be higher (p<0.05) than that of first station (Agri). Whereas, the levels of HDL in the second station (Erzurum) were found to be lower (p<0.05) than that of first station (Agri). Differences in the levels of total cholesterol and AST, ALT, HDL, LDL, triglyceride may be associated with size, sex, sexual maturity and environmental conditions (temperature, pH, hardness and dissolved oxygen).

    The results obtained on the model of starvation shows that nutritional dropsy led to the significant decrease of glucose, total cholesterol (TCh) and triglycerides (TC), as well as increase of non-estherified fatty acids (NEFA) in blood serum. In the rats with nutritional dropsy after treatment fed with standard diet enriched with soybean protein body weight returned to normal values as well as levels of Glucose, TCh and TC. However, concentration of NEFA remained increased. In the experimental group received additionally taurepar or taurhythman the level of NEFA decreased up to the normal one. It is necessary to mention that taurine derivatives did not change the biochemical parameters in blood of normal non-starved rats. We suppose that these new substances promote reduction of intensity of hyperlipidemic processes. It is known, that during starvation incomplete oxidation of fatty acids leads to acidosis with following destruction of mitochondria membraine. Finding property of taurine derivatives to decrease the concentration of non-estherified fatty acids points at their ability for restoration of tricarboxilic acid's cycle and prevention of accumulation of suboxidized molecules of NEFA and acidosis development.

    Full Text Available The biochemical analyses of the blood are largely used for the routine diagnosis and especially for the metabolic survey in farm animals. These facts conduct us to the idea that similar analyses, applied on honeybee hemolymph, could be used IN monitoring the healthy state of honeybee colonies. The present studies represent preliminary researches, which aimed to investigate the variability of the main biochemical parameters in the hemolymph of the healthy honeybees (Apis mellifera in inactive season. The researches were carried out on honeybee samples collected from 5 honeybee colonies belonging to a breeding apiary of the Institute for Beekeeping Research and Development from Bucharest.

    Full Text Available This paper presents the values of blood biochemical parameters of Simmental cows (n = 60, divided into five groups (dry cows, early puerperium, late puerperium, the fifth month of lactation, and cows with an extended service period. The ration for lactating cows contained an insufficient amount of dry matter, a third less than the lower limit of their requirements. In all examined groups of cows, a strong protein deficiency and excess calcium was found in the diet. Total protein concentration in all groups of cows were on the upper physiological limit, and the concentrations of bilirubin, carotene, vitamin A and total lipids were within the normal range. Low concentrations of urea in the third, fourth and fifth group of cows (3.1±0.39 mmol/l, 2.9±0.38 mmol/l and 3.3±0.43 mmol/l, respectively indicate the imbalance of protein and energy in the diet. The presence of an energy deficit is also indicated by the low blood glucose in all groups of cows, especially the second and fifth groups of cows (2.2±0.04 mmol/l and 2.3±0.07 mmol/l, respectively. The unfavorable ratio of calcium and phosphorus in the diet resulted in the narrowing of the calcium:phosporus ratio in blood serum, which is particularly evident in cows with an extended service period (2.1±0.07 mmol/l compared to 1.9± 0.11 mmol/l. Based on these results,we conclude that the tested herd exhibits subclinical health disorders, caused by an inadequate diet and with adverse effects on the productive and reproductive parameters.

    Full Text Available Background/Aim. During choledocholitiasis inflammatory oxidant stress involves the promotion of mitochondrial dysfunction through an intracellular oxidant stress in hepatocytes leading mainly to necrosis and less to apoptosis. The product of oxidative stress, malondialdehyde (MDA, is extremely cytotoxic and damages cell membranes and intracellular macromolecules. The toxicity of MDA is based on its ability to act as a mutagenic agent in a cell. Therefore, the aim of this prospective study was to establish correlation of the parameters of inflammation and biochemical markers of cholestasis with the intensity of oxidative stress in pathogenesis of liver function disorders. Methods. Seventy adult subjects of either sex included in the study were devided into two groups: I - 40 patients with obstructive icterus caused by choledocholithiasis, and II - 30 healthy individuals. All the participants were subjected to a clinical, laboratory and ultrasonic check-up at the Internal Department of the Military Hospital in Niš. The parameters of oxidative stress: MDA, a measure of lipid peroxidation, and inflammation parameters: C-reactive protein (CRP, fibrinogen, albumins, number of leukocytes (Leu, granulocytes ( Gr, lymphocytes (Ly and monocytes (Mo and biochemical markers of cholestasis: activity of γ-glutamyltransferase (γ-GT and alkaline phosphatase (AP enzymes, the level of total, direct and indirect bilirubin were determined by standard biochemical methods. Results. Lower values of albumin (p < 0.001, and significantly higher values of fibrinogen (p < 0.05 and CRP (p < 0.001 were found in the blood of the patients with cholestasis due to choledocholithiasis in relation to the controls. Significantly higher values of Leu (p < 0.01 and Gr (p < 0.001 with decreasing number of Ly (p < 0.001 and Mo (p < 0.001 were found in blood of the patients with cholestasis due to choledocholithiasis in relation to the control.

    Taking Dahlia pinnata 'Fenxishi' as test material, this paper studied its leaf physiological and biochemical responses to different degrees of drought stress and re-watering. With the increasing extent and duration of drought stress, the leaf relative water content, water potential, and chlorophyll content of D. pinnata 'Fenxishi' decreased significantly, leaf relative electric conductivity and malondialdehyde (MDA) content had a significant increase, plasma membrane was damaged, and massive ions were leaked out. The damage of plasma membrane was most serious under severe stress, and could not recover to the control level after re-watering. The leaf soluble sugar and proline contents also increased significantly with increasing extent and duration of drought stress. Especially for proline content, it was increased significantly in the later period of moderate and severe stresses, suggesting its lower sensitivity to water deficit. The leaf soluble protein content had a trend of down-up-down, while the activities of superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT) decreased after an initial increase. There were some differences in the responses of the three enzymes to drought stress and reactive oxygen, exhibiting their coordinating role.

    To evaluate the per capita availability of energy and macronutrients in the home and frequency of food consumption by adolescents and to relate them with anthropometric and biochemical variables, as well as verify if the eating habits of parents are associated to the children. We evaluated the weight, height, body fat (%BF), glucose, insulin, triglycerides, total cholesterol (TC) and fractions of 120 adolescents. We evaluated also the eating habits of adolescents and their parents. Adolescents with more than 35% of available lipids had 9.1-fold higher chances of presenting alterations in TC. Those who replaced the main meals for snacks had 3.66, 4.66 and 2.82 higher chances of presenting alterationsin %BF, insulin and triglycerides, respectively. The daily consumption of fruit was considered as a protective factor in relation to hyperinsulinemia. There was a similar feeding behavior among adolescents and their mothers. The results suggest the importance of specific attention to adolescent health, focused on family education. Copyright © AULA MEDICA EDICIONES 2013. Published by AULA MEDICA. All rights reserved.

    2000-01-01

    The objective of this work was to evaluate the effect of gamma radiation in reducing the bacterial population of the sugar cane must and verify its influence in the ethanolic fermentation. For this purpose, some microbiological and biochemical parameters of the ethanolic fermentation were analyzed, such as bacterial count; viability, replication and living replicates of the yeast; p H, acidity (total and volatile), glycerol and production of organic acids (acetic, lactic and succinic) during the fermentation; and fermentative yield. Bacteria of the genera Bacillus and Lactobacillus are the most common contaminants of the ethanolic fermentation and they might cause a decrease in the fermentative yield. The ionizing radiations may affect the microorganisms altering the DNA of the cells, which lose the ability to reproduce themselves and die. The experimental design was in randomized blocks (three) with one replicate in each block. The must was sugar-cane juice with approximately 5% of total reducing sugar. Bacteria of the following species were tested: Bacillus subtilis, Bacillus coagulans, Lactobacillus plantarum and Lactobacillus fermentum. The experiments were the inoculation of each bacteria separately in the must, the inoculation of the mixture of the four bacteria in the must and the use of natural sugar-cane juice with its own contaminating microorganisms. The contaminated must was irradiated with the doses of 0.0 (control), 2.0,4.0, 6.0, 8.0 and 10.0 kGy of gamma radiation (60-Cobalt) at an average rate of 2.0 kGy/h. After the irradiation, the fermentation of the must was carried out using the yeast Saccharomyces cerevisiae (Fleischmann). It was also accomplished an experiment with the inoculation of the mixture of the four bacteria in the must and, instead of using gamma radiation to decontaminate the must, it was used the antimicrobial Kamoran ID in the concentration of 3 ppm. The effects of the irradiation of the must were: reduction of the bacterial

    With the boom in industrialization, there is an increase in the level of heavy metals in the soil which drastically affect the growth and development of plants. Nickel is an essential micronutrient for plant growth and development, but elevated level of Ni causes stunted growth, chlorosis, nutrient imbalance, and alterations in the defense mechanism of plants in terms of accumulation of osmolytes or change in enzyme activities like guiacol peroxidase (POD), catalase (CAT), and superoxide dismutase (SOD). Ni-induced toxic response was studied in seedlings of finger millet, pearl millet, and oats in terms of seedling growth, lipid peroxidation, total chlorophyll, proline content, and enzymatic activities. On the basis of germination and growth parameters of the seedling, finger millet was found to be the most tolerant. Nickel accumulation was markedly lower in the shoots as compared to the roots, which was the highest in finger millet and the lowest in shoots of oats. Plants treated with a high concentration of Ni showed significant reduction in chlorophyll and increase in proline content. Considerable difference in level of malondialdehyde (MDA) content and activity of antioxidative enzymes indicates generation of redox imbalance in plants due to Ni-induced stress. Elevated activities of POD and SOD were observed with high concentrations of Ni while CAT activity was found to be reduced. It was observed that finger millet has higher capability to maintain homeostasis by keeping the balance between accumulation and ROS scavenging system than pearl millet and oats. The data provide insight into the physiological and biochemical changes in plants adapted to survive in Ni-rich environment. This study will help in selecting the more suitable crop species to be grown on Ni-rich soils.

    Full Text Available Cardamom is a strong antioxidant plant, so it is called the queen of spices. In the present study, we explored the potentials of cardamom on developmental, learning ability and biochemical parameters of mice offspring. Thirty pregnant mice were allocated to three groups of ten animals in each. Groups Π and Ш received pilsbury's Diet containing 10 and 20% of cardamom (w/w respectively, whereas Group I used as control. Cardomom was administered from the first day of pregnancy and was continued until post-natal day 15 (PD 15 and thereafter the mothers were switched to plain pilsbury's Diet. During the weaning period, three pups in each litter were color marked from the others, and were subjected to various tests (Physical assessment such body weight and eye opening and hair appearance; the neuromaturation of reflexes like righting, rotating, and cliff avoidance reflexes; learning ability and memory retention; estimation of monoamines neurotransmitters like dopamine and serotonin, non-enzymatic oxidative stress such as TBARS and GSH in forebrain at different ages of pups. The results indicated that the body weight gain was declining significantly. Hair appearance and eyes opening were delayed significantly. Righting, rotating, and cliff avoidance reflexes were delayed in treated animals. Exposure to cardamom led to enhance learning and memory retention as compared to control. Monoamines (DA, 5-HT and GSH were elevated, whereas TBARS was inhibited significantly. In conclusion, perinatal cardamom exposure enhanced learning and memory as compared to control. Cardamom and its benefit compounds were transported via placenta or/and milk during lactation. Cardamom needs more researches to investigate its benefits on other kinds of behavior.

    Full Text Available Introduction: Hunger and reduction in regular energy intake can lead to a number of problems based on their intensity. For instance, low energy level can cause blood cell production to decline or it may pose a higher risk of anemia. It can also weaken the immune system and platelet aggregation or negatively affect clot formation. This study aimed to have a closer look at fasting and regular physical activity and their impacts on body composition and blood hematological-biochemical parameters among professional wrestlers. Method: In this semi-experimental study, 9 subjects were selected by convenience sampling. The selected training program included participation in this exerciseprogram, 90 min per session, 6 times per week for a period of one month. Blood samples were obtained four times: before the start of Ramadan, 2 weeks after the start, during the last week and 2 weeks after the end of Ramadan. To make intra-group comparison, repeated measure analysis of variance was used. For all statistical comparisons, the level of significance was considered at PResults: Body weight and red blood cell count (RBC dropped significantly at the end of Ramadan (Respectively P= 0.001 and P=0.034. However, the number of white blood cells (WBC and circulating platelets (PLT significantly increased during fasting (Respectively P= 0.048 and P=0.042. As a matter of fact, PLT and WBC were the only factors which dramatically increased during fasting. Intra-group variations of tetracycline (TC, low-density lipoprotein (LDL, LDL: high-density lipoprotein (HDL, triglyceride (TG: HDL and TC: HDL reduced at the end of Ramadan. However, HDL levels ​​drastically increased during fasting (P≤0.05.

    Full Text Available Background: According to the high prevalence of cardiovascular diseases (CVDs in developing countries as well as high treatment expenses for patients and health-care systems, CVDs prevention in such societies has a great importance. One of the most effective strategies is improvement of knowledge and attitude towards the CVDs risk factors. This study aimed to evaluate the knowledge and attitude of females on CVDs risk factors and also the relationship between knowledge and attitude with obesity indices and biochemical parameters. Methods: This cross-sectional study was performed on 89 women with the age range of 11 to 67 y old and body mass index (BMI of 24 to 51 kg/m2. Participants were interviewed face to face using a valid questionnaire in order to evaluate their knowledge and attitude on CVDs risk factors. Blood sampling was implemented after 12 h of overnight fasting. Fasting blood glucose (FBG and lipid profile were assessed by enzymatic methods. Anthropometric measurements were performed and obesity indices were calculated. Results: More than 70% of participants had moderate or good knowledge and attitude about CVDs risk factors. Participant's knowledge and attitude had a significant positive association with educational level and a significant reverse relationship with age, total cholesterol, LDL-cholesterol, and obesity indices. Conclusions: Results of this study indicated that knowledge and attitude levels on CVDs risk factors affect the obesity indices and metabolic profile. Hence, knowledge and attitude enhancement is the main target and initial step in improving life quality and preventing cardiovascular diseases.

    The relationship between ultraviolet absorbance at 280 nm (UV280) and the 5-day Biochemical Oxygen Demand (BOD5) test was evaluated using wastewater samples collected during March - December 1998 from the Fort Meade wastewater treatment plant (Maryland, U.S.A.). Three types of samples were collected: raw influent wastewater, primary effluent, and the effluent from the nitrification settling basin. A regression of BOD5 on UV280 was obtained using half of the data, with the other half of the data used to test application of the equation. The presence of NO3 and NO2, did not interfere with the BOD5/UV relationship. However, the relative fraction of organic compounds that absorb at UV280 and are biodegradable did appear to decrease across the treatment plant, thereby reducing the strength of the association between BOD5 and UV280 further along the treatment train. Interestingly, the exclusion of solids > 1 microm from the BOD5 test did not strengthen the association between BOD5 and UV280. These results suggest that simple UV absorbance measurements may be a useful analytical tool for wastewater treatment personnel, allowing them to quickly monitor for changes in the BOD5 during the treatment process and to quickly estimate the BOD5 when determining what dilutions to use in the standard BOD5 test. However, such relationships are likely to be wastewater and treatment plant specific and variable with time and treatment.

    Full Text Available Amongst the numerous co-adjuvant therapies which could influence the incidence and progression of diabetic complications, antioxidants and flavonoids are currently being tested in clinical trials. We investigated the effect of naringerin on biochemical parameters in streptozotocin-induced (STZ - 60 mg/kg, i.p. diabetic rats. Male rats were divided into four groups: G1: untreated controls; G2: normal rats receiving naringerin; G3: untreated diabetics; G4: diabetics rats receiving naringerin. The naringerin (50mg/kg, i.p, decreased the hyperglycaemia and hyperlipidaemia associated with STZ-diabetes. The concentrations of serum insulin in treated diabetic rats tended to be increased. Naringerin treatment prevents STZ-induced changes in the activities of ALT, AST and LDH in the liver and heart, indicating the protective effect of naringerin against the hepatic and cardiac toxicity caused by STZ. The glycogen level in cardiac and hepatic tissues elevated with naringerin in diabetic rats. The naringerin can improve the glucose and lipid metabolism and is beneficial in preventing diabetic complications.Dentre as numerosas terapias para minimizar as complicações diabéticas, os antioxidantes e flavonoides são testados na clínica médica.

    The effects were studied of intravenous and intramuscular administration of radioprotectives cystamine and gammaphos in dogs on the biochemical parameters of the blood serum. The activities were studied of enzymes aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, creatinine kinase, gamma-glutamyl transpeptidase, lactate dehydrogenase, malate dehydrogenase, sorbitol dehydrogenase and alpha-amylase. The contents were determined of total protein, albumin, bilirubin, urea nitrogen, creatinine, glucose, triglycerides, cholesterol, lipids, calcium, sodium and potassium. Cystamine was shown to be hepatotoxic. The intramuscular administration of gammaphos was found to be more advantageous than of cystamine. Only slight increase was observed in the activities of lactate dehydrogenase, malate dehydrogenase, and alpha-amylase. With cystamine, the changes in all biochemical parameters were most marked.

    Folate metabolism is fundamental to several biological functions and required for cell replication, division, and survival. The mammalian folic acid cycle is highly complex and the enzymes, methylenetetrahydrofolate reductase (MTHFR), methionine synthase (MTR), and methionine synthase reductase (MTRR), have crucial roles in this metabolic pathway. The common polymorphisms of the MTHFR (C677T and A1298C), MTRR (A66G), and MTR (A2756G) enzymes are well documented as folate deficiency-related disorders, but their roles have not been examined in acromegalic patients. The aim of this study was to compare the genotypic distribution of these gene polymorphisms between patients with acromegaly and controls and explore whether these polymorphisms were associated with biochemical and hormonal parameters in acromegaly. We examined 91 acromegaly patients and 112 healthy subjects who were compared in terms of age and gender. Blood specimens of the subjects were collected in tubes containing ethylenediaminetetraacetic acid. Genomic DNA was isolated from peripheral blood leukocytes and genotyping of the MTHFR (C677T and A1298C) gene polymorphisms was assessed by melting temperature analyses after real-time polymerase chain reaction (PCR), whereas MTRR A66G and MTR A2756G gene polymorphism analyses were performed by PCR/restriction fragment length polymorphism from the isolated DNA of the subjects. MTHFR-677TT genotype frequency was significantly higher in the acromegaly group than the control group (p=0.017), and a significant increase was found in fibrinogen (p=0.032) levels in 677TT-carrying acromegaly patients. MTRR-66AA genotype was significantly higher in the control group than the acromegaly group (p=0.004). Total cholesterol (p=0.048) and C-reactive protein (p=0.046) levels decreased significantly in 66AA genotypes. Although MTR-2756AG genotype frequency was not different between the control and acromegaly groups, 2756AG genotype-carrying individuals have higher left

    The purpose of this study is to evaluate, using a questionnaire developed by our research group, whether occupational exposure to physical, chemical and psychosocial urban stressors can lead to alterations in perceived stress in a group of both male and female outdoor workers. The study also examines possible correlations between the levels of stress as inferred from the scores of the questionnaire and the levels of certain stress-related parameters (prolactin levels, consumption of coffee, chocolate, alcohol and cigarette smoking). We evaluated a final sample of 480 subjects (342 male and 138 female). All workers included in the study were divided into three groups on the basis of scores of the questionnaire. About 60% of workers showed a moderate or severe stress condition, with a statistically significant prevalence of female workers and younger subjects. There was a statistically significant correlation between the questionnaire score and the mean levels of stress-related parameters. The increase of perceived stress increases significantly the mean levels of prolactin and the consumption of coffee, chocolate and cigarettes. There was no statistically significant differences for alcohol consumption. The results show that exposure to chemical physical and psycho-social urban stressors can influence perceived stress in outdoor workers. The questionnaire used in our research could be an useful instruments for physicians during the health surveillance visits

    Within a series of regular projects investigating the suitability of biochemical parameters as biomarkers for the early recognition of environmental pollution, the levels of selected phenolic compounds were determined in Scots pine needles (Pinus sylvestris L.) from young and adult trees at three field sites with different SO{sub 2} pollution (Roesa>Taura>Neuglobsow). Young trees showed no differences in the levels of soluble phenolics in case of increasing loads of SO{sub 2}, whereas the concentration of the soluble phenolic component catechin in previous needles of adult trees altered significantly. In current year`s needles, differences were only found in the presence of high SO{sub 2} deposition. In contrast to catechin, picein and total phenolics remained unaffected. The concentration of catechin in the previous year`s needles of adult trees correlated positively with needle necroses. The phenolic components of the cell walls of pine needles were also analysed. The main phenolic compounds were identified as p-coumaric acid and ferulic acid. Differences in the levels of p-coumaric acid were detected in the needles of adult trees between the three sites, with the highest levels being measured at the site with the lowest pollution (Neuglobsow). However, changes in the p-coumaric acid content in young trees were low. No site-related differences were found regarding ferulic acid in adult and young pines. The findings are discussed and compared with data reported in the literature. (orig.)

    Anaerobic digestion of commercial food waste is a promising alternative to landfilling commercial food waste. This study characterized 11 types of commercial food wastes and 12 co-digestion blends. Bio-methane potential, biodegradable fraction, and apparent first-order hydrolysis rate coefficients were reported based upon biochemical methane potential (BMP) assays. Food waste bio-methane potentials ranged from 165 to 496 mL CH4/g VS. Substrates high in lipids or readily degradable carbohydrates showed the highest methane production. Average bio-methane potential observed for co-digested substrates was -5% to +20% that of the bio-methane potential of the individual substrates weighted by VS content. Apparent hydrolysis rate coefficients ranged from 0.19d(-1) to 0.65d(-1). Co-digested substrates showed an accelerated apparent hydrolysis rate relative to the weighted average of individual substrate rates. These results provide a database of key bio-digestion parameters to advance modeling and utilization of commercial food waste in anaerobic digestion. Copyright © 2016 Elsevier Ltd.

    Studies have shown that oxidative stress, found in patients with type 2 diabetes, may be due to changes in the metabolism of minerals, such as magnesium and iron. Data related to compartmentalization of these minerals in diabetes are scarce and controversial. This study assessed the influence of magnesium on biochemical parameters of iron and oxidative stress in patients with type 2 diabetes. A case-control study in male and female subjects aged 27-59 years, divided into two groups: type 2 diabetes (n=40) and control (n=48). Intake of magnesium and iron was assessed by three-day food record. Plasma, erythrocyte and urinary levels of magnesium, serum iron, ferritin, total iron binding capacity, fasting glucose, glycated hemoglobin, insulin, creatinine clearance and plasma thiobarbituric acid reactive substances (TBARS) were analyzed. Magnesium intake and plasma magnesium were lower in diabetic subjects. There was low urinary magnesium excretion, with no difference between groups. Although normal, the diabetic group had lower serum iron and ferritin concentrations compared to control subjects. Plasma TBARS in diabetic patients was higher than control while creatinine clearance was lower. An inverse correlation between erythrocyte magnesium and serum iron and ferritin was observed in the diabetes group. Diabetes induced hypomagnesemia and this, associated with chronic hyperglycemia, may have enhanced oxidative stress. Erythrocyte magnesium may have contributed to prevent iron overload and worsening of oxidative stress and hyperglycemic status. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

    This work investigated the effects of low and high doses of inorganic mercury in drinking water on biochemical parameters of pregnant rats and their offspring. Female Wistar rats were treated during pregnancy with 0, 0.2, 0.5, 10 or 50 μg Hg(2+)/mL as HgCl(2). Rats were euthanized on day 20 of pregnancy. Pregnant rats presented a decrease in total water intake in all doses of mercury tested. At high doses, a decrease in the total food intake and in body weight gain was observed. Pregnant rats exposed to 50 μg Hg(2+)/mL presented an increase in kidney relative weight. Mercury exposure did not change serum urea and creatinine levels in any of the doses tested. Moreover, mercury exposure did not change porphobilinogen synthase activity of kidney, liver and placenta from pregnant rats in any of the doses tested, whereas fetuses of pregnant rats exposed to 50 μg Hg(2+)/mL presented an increase in the hepatic porphobilinogen synthase activity. In general, pregnant rats presented alterations due to HgCl(2) exposure in drinking water. However, only the dose 50 μg Hg(2+)/mL appeared to be enough to cross the blood-placenta barrier, since at this dose the fetuses presented change in the porphobilinogen synthase activity.

  16. Remarkable analytic relations among greybody parameters

    2016-09-01

    In this paper we derive and discuss several implications of the analytic form of a modified blackbody, also called greybody, which is widely used in Astrophysics, and in particular in the study of star formation in the far-infrared/submillimetre domain. The research in this area has been greatly improved thanks to recent observations taken with the Herschel satellite, so that it became important to clarify the sense of the greybody approximation, to suggest possible further uses, and to delimit its intervals of validity. First, we discuss the position of the greybody peak, making difference between the optically thin and thick regimes. Second, we analyse the behaviour of bolometric quantities as a function of the different greybody parameters. The ratio between the bolometric luminosity and the mass of a source, the ratio between the so-called `submillimetre luminosity' and the bolometric one, and the bolometric temperature are observables used to characterize the evolutionary stage of a source, and it is of primary importance to have analytic equations describing the dependence of such quantities on the greybody parameters. Here we discuss all these aspects, providing analytic relations, illustrating particular cases, and providing graphical examples. Some equations reported here are well known in Astrophysics, but are often spread over different publications. Some of them, instead, are brand new and represent a novelty in Astrophysics literature. Finally, we indicate an alternative way to obtain, under some conditions, the greybody temperature and dust emissivity index directly from an observing spectral energy distribution, avoiding a best-fitting procedure.

    Variations in maternal blood parameters, which are mostly induced by the physiological changes that occur during pregnancy, have been reported in different gestational periods. The use of the established reference intervals for healthy adult females leads to the misclassification of healthy pregnant women as abnormal. Our aim was to establish appropriate reference intervals for biochemical, haematological and haemostatic parameters in the first and third trimesters of pregnancy. We included 565 healthy pregnant women with normal pregnancies. Blood samples were collected for biochemical analyses, complete blood counts and coagulation analyses at 8-12 and 28-37 weeks of gestation. The median and reference intervals (the 2.5th and 97.5th values) were calculated for each parameter during pregnancy and then compared to the established reference intervals for healthy adult females. Significant increases in triglyceride, total cholesterol, low-density lipoprotein cholesterol, uric acid, alkaline phosphatase, white blood cell, mean platelet volume, fibrinogen and D-dimer reference intervals and clear decreases in total protein, albumin, blood urea nitrogen, creatinine, red blood cell, haemoglobin, haematocrit, platelet counts and thrombin time reference intervals were observed during pregnancy. According to the 'n%', most changes were observed beginning in the first trimester. Compared to the established reference intervals, the greatest misclassifications were observed for ALB, ALP and D-Di. Changes in maternal blood parameters during pregnancy were confirmed. We recommend that the reference intervals for most blood parameters be revised to account for the gestational period.

    Analysis of 24 years of lunar laser ranging data is used to test the principle of equivalence, geodetic precession, the PPN parameters beta and gamma, and G/G. Recent data can be fitted with a rms scatter of 3 cm. (a) Using the Nordtvedt effect to test the principle of equivalence, it is found that the Moon and Earth accelerate alike in the Sun's field. The relative accelerations match to within 5 x 10(exp -13) . This limit, combined with an independent determination of y from planetary time delay, gives beta. Including the uncertainty due to compositional differences, the parameter beta differs from unity by no more than 0.0014; and, if the weak equivalence principle is satisfied, the difference is no more than 0.0006. (b) Geodetic precession matches its expected 19.2 marc sec/yr rate within 0.7%. This corresponds to a 1% test of gamma. (c) Apart from the Nordtvedt effect, beta and gamma can be tested from their influence on the lunar orbit. It is argued theoretically that the linear combination 0.8(beta) + 1.4(gamma) can be tested at the 1% level of accuracy. For solutions using numerically derived partial derivatives, higher sensitivity is found. Both 6 and y match the values of general relativity to within 0.005, and the linear combination beta+ gamma matches to within 0,003, but caution is advised due to the lack of theoretical understanding of these sensitivities. (d) No evidence for a changing gravitational constant is found, with absolute value of G/G less than or equal to 8 x lO(exp -12)/yr. There is significant sensitivity to G/G through solar perturbations on the lunar orbit.

    Swarna makshika (chalcopyrite) bhasma (SMB) has been used for different therapeutic purposes since long in Ayurveda. The present study is conducted to evaluate the effect of conventionally prepared SMB on different bio-chemical parameters in experimental animals, for providing scientific data base for its logical use in clinical practice. The genuine SMB was prepared by following classical techniques of shodhana and marana most commonly used by different Ayurvedic drug manufacturers. Shodhana was done by roasting raw swarna makshika with lemon juice for three days and marana was performed by 11 putas. The experimental animals (rats) were divided into two groups. SMB mixed with diluted honey was administered orally in therapeutic dose to Group SMB and diluted honey only was administered to vehicle control Group, for 30 days. The blood samples were collected twice, after 15 days and after 30 days of drug administration and different biochemical investigations were done. Biochemical parameters were chosen based on references from Ayurvedic classics and contemporary medicine. It was observed that Hb% was found significantly increased and LDL and VLDL were found significantly decreased in Group SMB when compared with vehicle control group. This experimental data will help the clinician for the logical use of SMB in different disease conditions with findings like low Hb% and high LDL, VLDL levels.

    Adverse impacts of immunity in terrestrial non-target organisms exposed to neonicotinoid insecticides have been reported, but the causal link between insecticide exposure and possible immune alterations in fish remains limited. In the present study, the potential genotoxicity and immunotoxicity of three neonicotinoids (imidacloprid, nitenpyram, and dinotefuran) were assessed in Chinese rare minnows by using a 60-day chronic toxicity test. The hematological and biochemical parameters of juvenile Chinese rare minnows and changes in the transcription of six inflammation-related genes were determined after exposure to neonicotinoids at 0.1, 0.5, or 2.0 mg/L. A clear difference in the frequency of erythrocytes with micronuclei (MN) was observed after treatment with 2.0 mg/L imidacloprid (p < .05). Additionally, exposure to 0.5 or 2.0 mg/L imidacloprid significantly increased the binucleated (BN) erythrocytes and those with notched nuclei (NT) (p < .05). A serum protein electrophoresis (SPE) assay showed significant alterations in the serum protein in all treatments (p < .05), and further analysis indicated decreases in immunoglobulin (Ig) in treatments with 0.5 or 2.0 mg/L imidacloprid or dinotefuran or with 0.1 mg/L nitenpyram (p < .05). Moreover, a biochemical assay confirmed that immunoglobulin M (IgM) levels were indeed significantly decreased upon treatment with imidacloprid or dinotefuran at 0.5 or 2.0 mg/L (p < .05). In addition, the transcriptional levels of the inflammatory cytokines IL-6, INF-α, TNF-α, and IL-1β were markedly down-regulated after all imidacloprid treatments (p < .05), whereas the expression levels of only TNF-α and IL-1β were significantly down-regulated following the 0.5 and 2.0 mg/L dinotefuran treatments (p < .05). Taken together, our results clearly demonstrate that imidacloprid, rather than nitenpyram and dinotefuran, can induce genotoxicity. The responsiveness of these immune indicators

    Oxytocin (OXT) is a neurohypophysial hormone which is synthesized in the paraventricular and supraoptic nuclei of the hypothalamus. OXT is currently attracting considerable attention because it has been discovered that it regulates various functions of behavior especially in the context of social interactions. OXT is a key component in bone formation, glycemia, male sexuality, cardiac differentiation and pregnancy and thus it is important to be further explored. The authors review various aspects of gestational diabetes, including definition, screening, diagnostic procedures, complications, clinical evaluation, indications of delivery and neonatal aspects. Not only the relation among diabetes mellitus, oxytocin and neurophysiology concerning erectile dysfunction, but also the role of OXT in the activity of arginine and vasopressin is investigated. It is imperative to develop technological and experimental methods that will be able to reveal the oxytocin and its potential.

    Full Text Available A. crassiflora Mart. a Brazilian savannah fruit, is a source of phytochemical compounds that possess a wide array of biological activities, including free radical scavenging. This native fruit proved to potentialize the mutagenic process in previous in vivo investigations. The aim of the present study was to investigate the effects of A. crassiflora Mart. pulp intake on colonic cell proliferation and on the development of Aberrant Crypt Foci (ACF in male Wistar rats. The animals were fed with either a commercial diet or a diet supplemented with A. crassiflora Mart. pulp mixed in 1%, 10% or 20% (w/w for 4 weeks or 20 weeks. The carcinogen 1,2-dimethylhydrazine dihydrochloride (4 doses, 40 mg kg-1 each was used to induce colonic ACF. After euthanasia, the blood, liver and colon samples were collected for biochemical determinations, oxidative stress or ACF development analysis, respectively. Immunohistochemical analyses of the colonic mucosa were performed using antibodies against proliferating cell nuclear antigen (PCNA in normal-appearing colonic crypt and β-catenin in ACF. There was no ACF development in the colon from groups treated with A. crassiflora Mart. pulp. Also, the biochemical and oxidative stress analysis, PCNA labeling and ACF development (number, multiplicity or cellular localization of β-catenin were unchanged as a result of marolo pulp intake. Thus, the present results suggest that A. crassiflora Mart. pulp intake did not exert any protective effect in the colon carcinogenesis induced by DMH in rats.

    Full Text Available The grass snake Natrix natrix (Linnaeus, 1758 is a partly hygrophilous species, distributed throughoutUkraine. This snake may be considered as a test object for environmental biomonitoring. Modern biochemical methods make it possible to obtain new scientific data on the effects of anthropogenic pressure on reptiles. Blood is a sensitive and informative indicator of the condition of an organism as it responds quickly to most changes in exogenous and endogenous factors, and reflects negative influences on both individual and, indirectly, populations. Changes in biochemical parameters may be used as biomarkers of the state of health of reptiles in ecosystems under varying degrees of anthropogenic pressure. Due the increase in anthropogenic influence the development and introduction of new methods of perceptual research, collection of up-to-date information and development of a database of reptile biochemical parameters have become an urgent priority. We collected mature individuals of the grass snake in floodplain ecosystems on the right bank of the Dnieper River in Dnipropetrovsk city. Grass snakes from floodplain habitats on the left bank of theSamaraRiver (O.L. Belgard Prysamarskii International Biosphere Station, Novomoskovsk district, Dnipropetrovsk province were studied as the control specimens. Our study demonstrated statistically significant differences between snakes from the study sites in the amount of albumin, urea and urea nitrogen, and inorganic phosphorus, as well as in alanine aminotransferase (ALT and alkaline phosphatise (AP activity. The amount of albumin in the blood serum of specimens from the anthropogenically transformed areas was significantly lower (by 25% than in that of the snakes caught in the control habitats. Decrease of the albumin concentration usually indicates abnormal processes in the kidneys and liver. According to the changes observed in the concentration of albumin, a corresponding increase in the albumin to

    To the best of our knowledge, any study about biochemical response of filamentous algae in the complex freshwater ecosystems has not been found in the literature. This study was designed to explore biochemical response of filamentous algae in different water bodies from May 2013 to October 2014, using multivariate approach in the South East of Turkey. Environmental variables were measured in situ: water temperature, oxygen concentration, saturation, conductivity, salinity, pH, redox potential, and total dissolved solid. Chemical variables of aqueous samples and biochemical compounds of filamentous algae were also measured. It was found that geographic position and anthropogenic activities had strong effect on physico-chemical variables of water bodies. Variation in environmental conditions caused change in algal biomass composition due to the different response of filamentous species, also indicated by FTIR analysis. Biochemical responses not only changed from species to species, but also varied for the same species at different sampling time and sampling stations. Multivariate analyses showed that heavy metals, nutrients, and water hardness were found as the important variables governing the temporal and spatial succession and biochemical compounds. Nutrients, especially nitrate, could stimulate pigment and total protein production, whereas high metal content had adverse effects. Amount of malondialdehyde (MDA), H2O2, total thiol groups, total phenolic compounds, proline, total carbohydrate, and metal bioaccumulation by filamentous algae could be closely related with heavy metals in the ecosystems. Significant increase in MDA, H2O2, total thiol group, total phenolic compounds, and proline productions by filamentous algae and chlorosis phenomenon seemed to be an important strategy for alleviating environmental factors-induced oxidative stress as biomarkers.

    Full Text Available This paper introduces an improved Differential Evolution algorithm (IDE which aims at improving its performance in estimating the relevant parameters for metabolic pathway data to simulate glycolysis pathway for yeast. Metabolic pathway data are expected to be of significant help in the development of efficient tools in kinetic modeling and parameter estimation platforms. Many computation algorithms face obstacles due to the noisy data and difficulty of the system in estimating myriad of parameters, and require longer computational time to estimate the relevant parameters. The proposed algorithm (IDE in this paper is a hybrid of a Differential Evolution algorithm (DE and a Kalman Filter (KF. The outcome of IDE is proven to be superior than Genetic Algorithm (GA and DE. The results of IDE from experiments show estimated optimal kinetic parameters values, shorter computation time and increased accuracy for simulated results compared with other estimation algorithms

    Morbid obesity needs to be treated by bariatric procedures. Proper dietary preparation of patients before surgery conditions their postoperative status. Assessment of dietary habits, nutritional status and biochemical parameters of the blood in patients being prepared for different bariatric procedures. The study involved a group of 27 obese adults: 19 women (mean age: 40.4 ±13.9 years) and 8 men (mean age: 39.6 ±12.7 years) qualified for bariatric procedures. Body composition, dietary habits and selected biochemical parameters of blood were assessed. Statistical analysis of the results was conducted using Statistica 9.0. Daily food rations consumed by women provided 1910.6 ±915.9 kcal/day, and by men 2631 ±1463.2 kcal/day on average. In both groups, the consumption of major nutrients was found to be inadequate. In both groups, deficiency was observed in the dietary intake of folic acid and potassium. Additionally, there was a decrease in the intake of vitamin D(3), calcium and iron in women and magnesium in men. In the two groups, disturbances were noted in lipid and carbohydrate metabolism. Our study indicates the necessity for dietary instructions in bariatric patients with regard to proper dietary habits and to reduce the risk of malnutrition before and after surgery.

    Trigonella foenum-graecum L. is enriched with many active ingredients. TFG oil was evaluated for its protective effect against deltamethrin toxicity in rats. Rats of the control group were administered saline. The 2nd group was administered deltamethrin (DLM) orally at a concentration of 15 mg/kg body mass. The 3rd and 4th groups were administered DLM at a concentration of 15 mg/kg body mass and were fed diets containing 2.5% and 5% TFG oil, respectively. DLM intoxication reduced red blood cell and platelet counts, hemoglobin concentration, and hematocrit value while it induced leucocytosis. Furthermore, it increased serum levels of lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, γ-glutamyltransferase, triglycerides, cholesterol, uric acid, urea, and creatinine; increased hepatic, renal, and brain lipid peroxidation; decreased serum acetylcholine esterase level; and decreased hepatic, renal, and brain antioxidant markers' activities. However, TFG oil kept the studied hematological and biochemical parameters within normal ranges. In addition, it prevented lipid peroxidation and oxidative stress induced by DLM intoxication in a dose-dependent manner. Therefore, these results indicated that TFG oil inhibited the toxic effects of DLM on hematological and biochemical parameters as well as oxidative status by its free radical scavenging and potent antioxidant activities, and it appeared to be a promising protective agent against DLM-induced toxicity.

    Full Text Available ABSTRACT Yucca schidigera Ortgies, Asparagaceae, is a herbaceous plant. Due to the high saponin content the powdered branches and leaves are used as natural food additive for human and animal. The aim of this study was to investigate the effects of Y. schidigera extracts on plasma leptin, ghrelin, adiponectin, insulin, thyroid hormones and some biochemical parameters in mice fed a high-fat diet. Male Swiss Albino mice were divided into seven equal groups. Group I (negative control group was given standard diet; Group II was given high-fat diet; Group III was given high-fat diet with carboxymethylcellulose; Groups IV–VII were given hexane, petroleum ether, ethyl acetate, and methanol extracts of Y. schidigera and high-fat diet via gastric gavage for 60 days. High-fat diet significantly increased plasma leptin, insulin, free T3 hormone, glucose, cholesterol, low-density lipoprotein, triacylglyceride, aspartate aminotransferase and alanine aminotransferase levels, and significantly decreased plasma ghrelin, adiponectin and free T4 hormone levels. On the other hand, hormone levels, lipid profile and biochemical parameters were improved by the administration of the PE extract. Y. schidigera extracts could be used as preventive medicine in nutritional disorders via regulating energy metabolism and hormonal functions.

    Frequent use of antibiotics to stimulate growth and health of animals leads to the development of antibiotic-resistant populations of microorganisms. In this context, alternatives like herbs and spices to antibiotics are of importance, as they are natural products. Therefore, the present experiment was designed to evaluate the performance, carcass traits, hematology and serum biochemical parameters of broilers fed ration containing varying levels of Lepidium satvium (Garden cress) seed powder as feed additive up to the age of 42 days. A total of 204 Cobb-500 day-old broiler chicks were randomly distributed into four treatments with three replicates of 17 chicks each. Garden cress (GC) was included in the ration at 0 (0GC), 0.75 (0.75GC), 1.50 (1.5GC) and 2.25 % (2.25GC) in each treatments. Growth performance, carcass characteristics, heamatology, serum biochemical and economic efficiency parameters were observed. The crude protein, ether extract and crude fiber content of GC were 22.4, 25.7 and 10.5 %, respectively. Daily dry matter intake and average daily gain during the entire experimental period were affected (p  0.05). Sex differences were significant for eviscerated, carcass and kidney percentages with greater values for females than males. All hematological parameters were within the normal range. However, inclusion of GC improved (p health of broilers. Based on the production parameters used in the study, GC can be included as feed additive at a level of 0.75 % in the total ration for better and positive results on biological performance and health status of broilers.

    We performed numerical analysis and design parameter optimization of a silicon-based grating waveguide refractive index (RI) sensor. The performance of the grating waveguide RI sensor was determined by the full-width at half-maximum (FWHM) and the shift in the resonance wavelength in the transmission spectrum. The transmission extinction, a major figure-of-merit of an RI sensor that reflects both FWHM and resonance shift performance, could be significantly improved by the proper determination of three major grating waveguide parameters: duty ratio, grating period, and etching depth. We analyzed the transmission characteristics of the grating waveguide under various design parameter conditions using a finite-difference time domain method. We achieved a transmission extinction improvement of >26 dB under a given bioenvironmental target change by the proper choice of the design procedure and parameters. This design procedure and choice of appropriate parameters would enable the widespread application of silicon-based grating waveguide in high-performance RI biochemical sensor.

Radio frequency signals of 1800 MHz (continuous wave transmission, 217 Hz modulate and Global System for Mobile Communications [GSM - non-DTX]) with 1.09 w/kg specific absorption rate (SAR) value were used for 15 and 30 min. Cell phone radiation induced a significant increase of superoxide dismutase (SOD); there was a statistically significant effect of talking time on the levels of SOD, F(2, 33) = 8.084, p < 0.05, ω = 0.53. The trend analysis suggests a significant quadratic trend, F(1, 33) = 4.891, p < 0.05; indicating that after 15 min of talking the levels of SOD increased, but as talking time increased the SOD activity started to drop. In contrast to this, there was no statistically significant effect of talking time on the level of salivary albumin, cytochrome c, catalase or uric acid. Results suggest that exposure to electromagnetic radiation may exert an oxidative stress on human cells as evidenced by the increase in the concentration of the superoxide radical anion released in the saliva of cell phone users.

    Flacourtia montana an endemic species of Western Ghat which is well known for its ethno-medicinal value was chosen for the study. Matured seeds collected from Beithangady region of Dakshina Kannada district were irradiated with different doses (0, 25, 50, 100, 150, 200, 250, 300 Gy) of gamma radiation using 60 Co gamma source at Board of Radiation and Isotope Technology (BRIT). Effect of gamma radiation on growth and biochemical constituents were compared with that of control plants. An increase in germination percentage, speed and vigour index was observed at lower dosages, and the dose of 100 Gy was found to be more effective out of the selected doses as far as growth is concerned. Doses of 25 and 100 Gy showed 95 and 100% germination respectively but the germination was reduced at higher dosages. Total chlorophyll content at 10 Gy was found to be 19.56 mg/gfw while in control was 14 mg/gfw. Phenolic content was higher at 50 Gy and proline content at 150 Gy. Slight increase in carbohydrate content was observed in irradiated samples. Hence, lower doses of radiation treatment may be recommended to increase growth and phenolic content of plant F.montana.

    Cadmium (Cd) is a toxic environmental and occupational pollutant with reported toxic effects on the kidneys, liver, lungs, bones, and the immunity system. Based on its physicochemical similarity to cadmium, zinc (Zn) shows protective effects against cadmium toxicity and cadmium accumulation in the body. Nano-zinc and nano-zinc oxide (ZnO), recently used in foods and pharmaceutical products, can release a great amount of Zn 2+ in their environment. This research was carried out to investigate the more potent properties of the metal zinc among sub-acute cadmium intoxicated rats. Seventy-five male Wistar rats were caged in 15 groups. Cadmium chloride (CdCl 2 ) was used in drinking water to induce cadmium toxicity. Different sizes (15, 20, and 30 nm) and doses of nano-zinc particles (3, 10, 100 mg/kg body weight [bw]) were administered solely and simultaneously with CdCl 2 (2-5 mg/kg bw) for 28 days. The experimental animals were decapitated, and the biochemical biomarkers (enzymatic and non-enzymatic) were determined in their serum after oral exposure to nano-zinc and cadmium. Statistical analysis was carried out with a one-way ANOVA and t test. P cadmium- and nano-zinc-treated rats compared with the controls. However, albumin, total protein, and HDLc significantly decreased in the cadmium- and nano-zinc-treated rats compared with the controls (P cadmium intoxication.

    A laboratory-scale study was conducted on the batch anaerobic digestion of sunflower oil cake (SuOC), solid waste derived from the extraction process of sunflower oil. A multi-reactor system was used to compare methane production from this waste at inoculum to substrate ratios (ISRs) of 3.0, 2.0, 1.5, 1.0, 0.8 and 0.5 (expressed as volatile solids (VS) basis). The tests were carried out at mesophilic temperature (35 C) and run against a control of inoculum without substrate. The results obtained in the biochemical methane potential (BMP) tests showed that the ultimate methane yield (Y{sub M,ult}) decreased considerably from 227{+-}23 to 107{+-}11 ml CH{sub 4} at standard temperature and pressure (STP) conditions g{sup -1} VS{sub added} when the ISR decreased from 3.0 to 0.5, showing a clear influence of the ISR on the methane yield coefficient. The biodegradability (BD) of the waste also decreased from 86% to 41% when the ISR varied from 3.0 to 0.5. A net total ammonia nitrogen (TAN) yield of 39.2 mg N g{sup -1} VS{sub added} was obtained, and this value was not influenced by the ISRs assayed, which demonstrated the appropriate operation of the hydrolytic-acidogenic stage of the overall digestion process. A clear imbalance of the methanogenic process was observed at the lowest ISRs studied (0.5 and 0.8) due to a considerable increase in CODs and TVFA in the digestates. The profile of VFA was also influenced by the ISR, typical of the proteinaceous substrates. (author)

    Full Text Available Abstract Background The abolition of in-feed antibiotics or chemotherapeutics as growth promoters have stimulated the swine industry to look for alternatives such as organic acids, botanicals, probiotics and tannin. The objective of the present study was to compare the effects of a combination of acids and tannin with diet with organic acids and diet without growth promoters on the growth performance and selected biochemical, haematological and antioxidant enzyme parameters in grower pigs. Tannin is more natural and cheaper but possibly with the same effectiveness as organic acids with regard to growth performance. Methods Thirty-six 7 week old grower pigs, divided into three equal groups, were used in a three week feeding trial. Group I was fed basal diet, group II basal diet with added organic acids and group III basal diet with added organic and inorganic acids and tannin. Pigs were weighed before and after feeding and observed daily. Blood was collected before and after the feeding trial for the determination of selected biochemical, haematological and antioxidant enzyme parameters. One-way ANOVA was used to assess any diet related changes of all the parameters. Paired t-test was used to evaluate changes of blood parameters individually in each group of growers before and after feeding. Results No clinical health problems related to diet were noted during the three week feeding trial. The average daily gain (ADG and selected blood parameters were not affected by the addition to basal diet of either acids and tannin or of organic acids alone. Selected blood parameters remained within the reference range before and after the feeding trial, with the exception of total serum proteins that were below the lower value of reference range at both times. The significant changes (paired t-test observed in individual groups before and after the feeding trial are related to the growth of pigs. Conclusion Diet with acids and tannin did not improve the

    To define groups of patients according to the changes of biochemical parameters, that is, serum calcium, phosphate and parathyroid hormone (PTH), over a 2-year follow-up period using group-based multi-trajectory modeling (GBMM) among a cohort of dialysis patients with newly diagnosed secondary hyperparathyroidism (SHPT) (ie, PTH≥500 ng/L for the first time) and to compare their patient characteristics and treatments. Pharmacoepidemiological study. In the 12 dialysis units located in the French region of Lorraine. A total of 269 dialysis patients with newly diagnosed SHPT were prospectively included from December 2009 to May 2012 and followed-up for 2 years. We identified four distinct trajectory groups: 'rapid PTH drop' experiencing a rapid and sharp decrease (over weeks) in PTH level associated with decreasing phosphate level within normal range (n=34; 12.7%), 'gradual PTH decrease' experiencing a gradual and continuous decrease (over months) in PTH level and maintaining phosphate at a middle level throughout the study (n=98; 36.4%), 'slow PTH decrease with high phosphate' experiencing a slow decrease in PTH level associated with a relatively high phosphate level (n=105; 39.0%) and 'uncontrolled SHPT' with high levels of PTH and phosphate throughout the study (n=32; 11.9%). Patients in the 'uncontrolled SHPT' group were significantly (p<0.00001) younger than patients in other groups. Kidney Disease Improving Global Outcomes (KDIGO) targets for PTH, phosphate and calcium were reached simultaneously for 14.9% of patients at baseline and 16.7% at the end of the study. Patients were given cinacalcet more frequently at months 3 and 6 in the 'rapid PTH drop' and at month 24 in the 'uncontrolled SHPT' groups. Over 2 years following a new SHPT diagnosis, a younger age and a higher rate of alkaline phosphatase were associated to a continuous uncontrolled SHPT. Patients with the lowest PTH at the end of the follow-up tended to receive more often cinacalcet. Clinical

    The subchronic effect of aqueous stem bark extract of Khaya senegalensis on some biochemical, haematological, and histopathological parameters of rats was investigated. The rats were divided into six groups of five rats per group. Groups I to VI were administered graded doses of 0, 400, 800, 1200, 1600, and 2000 mg/kg bw, respectively. The result of study revealed that administration of the Khaya senegalensis for twenty-eight days at the experimental dose resulted in significant (P < 0.05) increase in urea, electrolytes (Na(+), K(+)), and creatinine levels. The extract also significantly (P < 0.05) increased serum activity of ALT, AST, and ALP. The levels of protein, albumin, and bilirubin were significantly changed when compared to their control values, but they were not dose dependent. The hematological indices assayed in this study were not significantly affected at the experimental dose when compared to the control values. Histological studies of the liver showed cellular degeneration and necrosis and bile duct hyperplasia and fibrosis with lymphocytic infiltration of the hepatocyte, providing supportive evidence for discussing the biochemical findings, indicative of functional derangement. The histological architecture of the kidney and that of the heart were however preserved. The result of this study indicates that the aqueous stem bark extract of K. senegalensis may affect the cellular integrity of vital organs of the body.

Methodology and Results: Three species of cyanobacteria (Anabaena laxa, Anabaena fertilissima and Nostoc muscorum were collected from the culture collection of Soils, Water and Environment Research Institute, Agriculture Research Center, Giza, Egypt, to investigate their biochemical composition under different growth conditions, using BG110 (nitrogen free as growth medium. These conditions were represented by control medium, static glucose medium with (1%, w/v, aerated medium (aerated by bubbling technique depending on CO2 normally existed in air with a concentration of 0.03%, molasses medium (0.7%, v/v and aerated medium enriched with glucose (1%, w/v. Lipid content, total carbohydrates, soluble proteins and free amino acids were determined at the previous conditions. Glucose at 0.7% (w/v was the most favorable for lipid production in A. laxa, where it exhibited the highest lipid content (427 μg/g fresh wt.. Increasing molasses concentration up to 0.7% (v/v produced an increase in lipid contents of the tested cyanobacterial strains. The highest lipid content of both N. muscorum (366.2 μg/g fresh wt. and A. laxa (357.4 μg/g fresh wt. were recorded at molasses concentrations of 0.1 and 0.7% (v/v, respectively. A. laxa expressed high significant values for both proteins (31.6 μg/mL and free amino acids (40.5 mg/g dry wt. after 6 days of incubation period under aerated enriched glucose condition (1%, w/v. Also, at the same growth conditions, A. fertilissima exhibited high significant values for carbohydrates at 4th day (876.8 mg/g dry wt.. Conclusion, significance and impact of study: Aerated enriched glucose medium (1%, w/v was the best growth medium condition used in the present study.

    Twenty cows in mid-lactation were randomly ground into 4 diets with dietary cation-anion balance (DCAB, mEq/100 g dry matter) values of 87 (control), 300, 400 and 500 to measure the effect of DCAB on blood biochemical parameters and urine index. In blood, luteotropin significantly increased at DCAB 400 fed sample, estradiol (E2) and urea decreased at DCAB 400 and 500 fed sample. However, Lactate dehydrogenate, creatine phosphokinase and total protein had a significant increase for DCAB 300 and 400 fed sample. Calcium for all treatments significantly increased. In urine, Urea and pH significantly increased, but K + reduced at DCAB 400 and 500 fed sample. Cl - was lower for all treatments, and Na + was higher for DCAB 300 and 500 fed sample. Urea was enhanced at DCAB 400 feed. DCAB 400 is suited as the feed for midlactation cows. (authors)

    Triplicate groups of fed and starved olive flounder, Paralichthys olivaceus (body weight: 119.8±17.46 g), were examined over 42 days for physiological changes using hematological, biochemical, and non-specific immune parameters. No significant differences in concentrations of blood hemoglobin and hematocrit and plasma levels of total cholesterol, aspartate aminotransferase, alanine aminotransferase, glucose, and cortisol were detected between fed and starved groups at any sampling time throughout the experiment. In contrast, plasma total protein concentrations were significantly lower in starved fish than in fed fish from day 7 onwards. Moreover, plasma lysozyme concentrations were significantly higher in starved flounder from day 21 onwards. This result confirms that the response of olive flounder to short-term (less than about 1.5 months) starvation consists of a readjustment of metabolism rather than the activation of an alarm-stress response. The present results indicate that starvation does not significantly compromise the health status of fish despite food limitation.

    Full Text Available Soil salinity occupies a prominent place among the soil problems that threaten the sustainability of agriculture over a vast area in the world. It affects plant morpho-physiology and ultimately leads to reduction in productivity. It is essential to test important medicinal plants for their salinity tolerance as research efforts aim to explore economic benefits under saline conditions. Keeping in view the importance of Stevia and salinity, present study had been designed to investigate the effect of salinity on biochemical parameters in two Stevia genotypes. Two node microcuttings were subjected to MS media supplemented with different NaCl concentrations (0, 25, 50, 75, 100, 125 mM. Chlorophyll amount was observed to be decreased as compared to sugars, proline and phenols with increased salt concentrations.

    The present study investigated the effects of different dietary nettle (Urtica dioica) levels on biochemical, hematological and immunological parameters in beluga (Huso huso). Fish were divided into 4 groups before being fed for 8 weeks with 0%, 3%, 6% and 12% of nettle. The blood samples were collected on week 4 and 8. The use of nettle did not significantly change the mean cell volume, mean cell haemoglobin, lymphocytes, eosinophils, albumin, glucose, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and lysozyme activity on week 4 and 8. After 4 weeks, the total red blood cell (RBC) and hematocrit (Ht) showed a significant increase in 12% nettle group compared to the 3% nettle and control groups but haemoglobin (Hb) had a significant change in 12% nettle compared to the control. At the same time was not found a significant change in the mean cell haemoglobin concentration (MCHC), total white blood cell (WBC), neutrophils, respiratory burst activity (RB), total immunoglobulin (Ig) and total protein (TP), triglyceride (Tri) and cholesterol (Chol). After 8 weeks, the fish treated with nettle exhibited significantly increase in neutrophil and Hb levels compared to the control and between treatment groups, 12% nettle group shown the highest Hb while RBC and Hct values significantly rose in fish fed by 12% compared to the control. Supplementing 6% and 12% nettle increased the WBC and MCHC compared to the other groups. The group fed 12% showed a highly significant difference in RB, TP and Ig after 8 weeks. However, Tri and Chol were significantly decreased in the juvenile beluga fed by the 6% and 12% nettle diet compared to the other groups. The results suggest that by using this herb there will be an improvement in hemato-biochemical parameters and immune function of juvenile beluga.

    An influence of various humic-plant feed additives based on some herbs (nettle, chamomile, yarrow, perforatum), lucerne and humic materials on biochemical indices of Lohmann Brown (LB) layers blood plasma was estimated. Hens were housed in deep litter system, 20 birds in a group. Four groups were formed: control (C - standard feeding), and experimental, supplemented with prepara- tions: E-1 herbal-humic, E-2 humic-herbal and E-3--humic-lucerne. Hens were placed in the pens on the 16th week of life, addition of preparations with standard food mixture started at the 22nd wk and lasted until 66th wk of life. Blood for analyses was collected four times in the following periods: 27, 37, 54 and 65th wk of life. The applied humic-plant preparations to a limited degree affected the values of examined biochemical parameters in serum: total protein (TP), albumins (Albs), glucose (Glu), urea, triacylglycerols (TAG), total cholesterol (TCh), alanine aminotransferase (ALT), aspartate aminot- ransferase (AST) and alkaline phosphatase (ALP). It is difficult to determine based on these study, which preparation is one the most active biologically, however is seems that humic-lucerne prepara- tion affected the examined blood parameters to the highest degree. The reference values ranges in hens blood serum LB hens were proposed for: TP (43-65 g/l), Albs (15-22 g/l), urea (0.5-1.2 mmol/l), Glu 10-15 mmol/l), TCh (2.2-4.5 mmol/l), TAG (10-24 mmol/l), AST (4-12 U/l), ALT (150-280 mmol/l) and ALP (190-350 U/l).

    Full Text Available The effects of different dietary electrolyte balance (DEB on growth performance, nitrogen (N metabolism and some blood biochemical parameters were investigated in 2 to 3 months old growing rabbits. A total of 150 growing rabbits of 2 months age were randomly divided into five groups according to average body weight, with 30 rabbits in each group. The DEB levels of the five experimental diets were −154, −3.16, +201, +347, and +500 meq/kg of dry matter (DM, respectively. There was a 7-d adaptation period and a 23-d experimental period. The results showed that the DEB levels had a quadratic affect on the average daily feed intake (ADFI (p<0.001. The greatest ADFI was achieved when the DEB level was +201 meq/kg DM. Fecal N (FN content linearly decreased (0.047, while digestible N (DN, retained N (RN, efficiency of intake N converted into digestible N (DN/IN and the efficiency of intake N converted into retained N (RN/IN linearly increased with the DEB increase (0.020, 0.004, 0.021, and 0.049, respectively. Serum phosphorus (P ion content linearly increased with the DEB increase (p = 0.036. The DEB had a quadratic relationship with serum anion gap (AG (p = 0.002 and serum parathyroid hormone (PTH content (p = 0.016. The DEB levels quadratically affected base excess (BE in the plasma (p<0.001. In conclusion, the DEB unaffected growth performance but affected feed intake, N metabolism and some blood biochemical parameters of growing rabbits.

    The influence of hydrocortisone acetate treatment (4 mg/100 g body weight i.m. and daily injected) was studied in pregnant rats and their litters. The parameters controlled were: food intake, body weight and body nitrogen, and liver enzimatic activity of PEPCK, in the mothers and number of foetus, weight, body nitrogen content and liver PEPCK activity in the litter. The hormonal treatment induces a significant reduction of food intake and weight of the mothers. In the same way the total body nitrogen content, is reduced but not its concentration (body nitrogen content/g body weight). Likewise, cortisone injection reduces the number of newborns, and, significantly, the individual weight of the same. At the 21st gestation day, the nitrogen content of the litter, given by g of weight, is also significantly reduced. Liver activity of PEPCK was significantly increased in the pregnant rat in all days under study and was not detected in the foetus in the 21st day.

    Full Text Available In hemodialysis patients, deviations from KDIGO recommended values of individual parameters, phosphate, calcium or parathyroid hormone (PTH, are associated with increased mortality. However, it is widely accepted that these parameters are not regulated independently of each other and that therapy aimed to correct one parameter often modifies the others. The aim of the present study is to quantify the degree of association between parameters of chronic kidney disease and mineral bone disease (CKD-MBD.Data was extracted from a cohort of 1758 adult HD patients between January 2000 and June 2013 obtaining a total of 46.141 records (10 year follow-up. We used an advanced data analysis system called Random Forest (RF which is based on self-learning procedure with similar axioms to those utilized for the development of artificial intelligence. This new approach is particularly useful when the variables analyzed are closely dependent to each other.The analysis revealed a strong association between PTH and phosphate that was superior to that of PTH and Calcium. The classical linear regression analysis between PTH and phosphate shows a correlation coefficient is 0.27, p<0.001, the possibility to predict PTH changes from phosphate modification is marginal. Alternatively, RF assumes that changes in phosphate will cause modifications in other associated variables (calcium and others that may also affect PTH values. Using RF the correlation coefficient between changes in serum PTH and phosphate is 0.77, p<0.001; thus, the power of prediction is markedly increased. The effect of therapy on biochemical variables was also analyzed using this RF.Our results suggest that the analysis of the complex interactions between mineral metabolism parameters in CKD-MBD may demand a more advanced data analysis system such as RF.

    Full Text Available ABSTRACT: This study aimed to evaluate the influence of replacing soybean oil with extra virgin coconut oil in normolipidic and hyperlipidic diets, on the lipid metabolism of Wistar rats. In the first stage of the experiment (30 days, 36 rats were divided into 2 groups and fed with a control or a hyperlipidic diet. Six animals from each group were then killed, and the remaining rats were redistributed into 4 new groups: 2 groups remained on the control and hyperlipidic diets, and in the diets of the other 2 groups, the soybean oil was replaced with coconut oil (30 days. At the end of the assay, the biological models were decapitated for blood collection and removal of organs and peritoneal fat. Although the diet intake differed among groups during both stages of the experiment, no differences were noted with regard to weight gain and peritoneal fat. Replacing soybean oil with coconut oil in the rat diet lowered triglyceride and low-density lipoprotein serum concentrations in both groups. Liver parameters, namely, total cholesterol and triacylglycerols, increased with the substitution of soybean oil by coconut oil in the normolipidic diet and decreased in the hyperlipidic diet. Thus, replacing soybean oil by coconut oil may improve serum and liver lipid levels in Wistar rats.

    To investigate the therapeutical effect of vitamin D supplementation on the metabolism and endocrine parameters of PCOS patients. Clinical studies investigating the therapeutic effect of vitamin D supplementation on PCOS patients were selected by searching PubMed, Embase, The Cochrane library and Web of Science until April 2016. The included articles were selected according to the inclusion criteria. Serum HOMA-IR, QUICKI, LDL, DHEAS, free testosterone (FT), total testosterone (TT), PTH, 25-hydroxy-vitamin D, and triglyceride of PCOS patients were enrolled for evaluating the therapeutic effects of vitamin D. 16 studies were included in this study. There was no significant difference between the placebo group and vitamin D group in the concentration of serum 25-hydroxy-vitamin D in patients with PCOS (P = 0.06). After treated with vitamin D, the serum 25-hydroxy-vitamin D in PCOS patients was increased (P HOMA-IR, QUICKI, LDL, DHEAS, FT, and TT in PCOS patients did not change. Subgroup analysis showed that the serum triglyceride of PCOS patients was decreased by low dose of vitamin D supplementation (HOMA-IR, QUICKI, LDL, DHEAS, FT, and TT. Furthermore, less than 50,000 IU vitamin D supplementation is sufficient for decreasing serum triglyceride.

    Full Text Available Sporting competitions are becoming more demanding in terms of intensity of effort, and this means controlling all aspects that affect athletic performance. Food, hydration and supplementation, before, during and after training or competition directly affect health, body composition, performance and recovery of the athlete. The assessment of nutritional status is required for proper advising of the athlete, through blood tests to control the process of adaptation to training. The aim of this paper is to provide practical tools for dietitiansnutritionists to control the health and nutritional status of athletes, as well as monitoring their adaptation to workloads and competition periods. Performing analytical tests to control of protein metabolism, lipid profile, ions, blood tests and iron metabolism, in addition to review some hormonal parameters, may be of interest in order to observe the potential existence of overtraining states. The correct understanding and interpretation of laboratory tests (under sports doctor’s supervision will be most important and useful for dietitiansnutritionists, performing dietary and nutritional advice to athletes, because it will determine the status of the athlete and propose different individual feeding strategies depending on the training phase and response.

    Zinc (Zn) and chromium (Cr) act as essential nutrients; however, they can be toxic at higher concentrations. In this study, earthworm species Eudrilus eugeniae was studied for its sensitivity to sublethal doses of Cr (8 ppm) and Zn (350 ppm) in terms of alterations occurred in oxidative stress indices and reproductive parameters in the testis. A significant (p food intake was observed on 7, 14 and 21 days of Cr toxicity; while increased rate was evident upon 7 days of Zn exposure. Changes evident in the rate of cocoon production (-39.54 and +38.63 %), hatchability (-77.85 and +30.0 %) highlight higher toxic potential of Cr than Zn, respectively. Moderate to severe vacuolization in spermatic follicles and higher incidence of tailless (+52.6 % in Cr and 20.8 % in Zn), and head bent (+18.8 % in Cr and 0 % in Zn) sperms were evident in Cr(VI) exposed worms emphasizing the higher vulnerability of E. eugeniae to Cr toxicity. A significant (p implied from results that excessive free radical production and inadequate antioxidant defenses have lead to morphological alterations in sperms which sequentially reduced the reproductive rate.

    Full Text Available OBJECTIVES: Tension cost, the ratio of myosin ATPase activity to tension, reflects the economy of tension development in the myocardium. To evaluate the mechanical advantage represented by the tension cost, we studied papillary muscle contractility and the activity of myosin ATPase in the left ventricles in normal and pathophysiological conditions. METHODS: Experimental protocols were performed using rat left ventricles from: (1 streptozotocin-induced diabetic and control Wistar rats; (2 N-nitro-L-arginine methyl ester (L-NAME hypertensive and untreated Wistar rats; (3 deoxycorticosterone acetate (DOCA salt-treated, nephrectomized and salt- and DOCA-treated rats; (4 spontaneous hypertensive rats (SHR and Wistar Kyoto (WKY rats; (5 rats with myocardial infarction and shamoperated rats. The isometric force, tetanic tension, and the activity of myosin ATPase were measured. RESULTS: The results obtained from infarcted, diabetic, and deoxycorticosterone acetate-salt-treated rats showed reductions in twitch and tetanic tension compared to the control and sham-operated groups. Twitch and tetanic tension increased in the N-nitro-L-arginine methyl ester-treated rats compared with the Wistar rats. Myosin ATPase activity was depressed in the infarcted, diabetic, and deoxycorticosterone acetate salt-treated rats compared with control and sham-operated rats and was increased in N-nitro-L-arginine methyl ester-treated rats. These parameters did not differ between SHR and WKY rats. In the studied conditions (e.g., post-myocardial infarction, deoxycorticosterone acetate salt-induced hypertension, chronic N-nitro-L-arginine methyl ester treatment, and streptozotocin-induced diabetes, a positive correlation between force or plateau tetanic tension and myosin ATPase activity was observed. CONCLUSION: Our results suggest that the myocardium adapts to force generation by increasing or reducing the tension cost to maintain myocardial contractility with a better

    There is generally a dearth of information involving reference ranges of health variables for numerous elasmobranch species commonly housed in zoos and aquaria; thus, extrapolation from a few existing elasmobranch studies is commonly used to assess health parameters in these species. The primary objective of this study was to establish baseline complete blood cell count and plasma chemistry reference ranges for captive individuals of the cownose ray Rhinoptera bonasus, an elasmobranch that is widely displayed in zoos and aquaria worldwide. This study was conducted using 18 adult cownose rays currently housed at the Mystic Aquarium and Institute for Exploration in Connecticut. Median blood and plasma values were 550 cells/microL for total white blood cell count; 511,250 cells/microL for total red blood cell count; 31% for packed cell volume; 5.8 g/L for total solids; 2.85 g/dL for total protein; 33 units (U)/L for aspartate aminotransferase; 34 U/L for alkaline phosphatase; 0.2 mg/dL for total bilirubin; 1,155 mg/dL for urea nitrogen; 0.1 mg/dL for creatinine; 0.6 g/dL for albumin; 2.15 g/dL for globulins; 144 mg/dL for cholesterol; 157 mg/dL for triglycerides; 45 mg/dL for glucose; 16.9 mg/dL for calcium; 5.8 mg/dL for phosphorus; 294 mmol/L for sodium; 1.55 mmol/L for potassium; and 270 mmol/L for chloride. Gamma glutamyl transpeptidase, amylase, creatine kinase, and lactate dehydrogenase were below the detectable limits for several samples. In nine samples, alanine aminotransferase levels were below the instrument range (< 4 U/L). No significant differences between sexes were detected. The reference ranges reported in this study should provide a useful guide for routine health monitoring of captive cownose rays.

    This study examines the effect of water-current speed on hematological, biochemical and immune parameters in juvenile tinfoil barb ( Barbonymus schwanenfeldii). Blood samples were taken on days 1, 23 and 45 from control fish and from two training groups maintained at current speeds of 0.06 bl/s (body length per second), 0.66 bl/s, and 1.92 bl/s, respectively. Significantly increased red-blood-cell counts and hematocrit were observed in the post-training groups on days 23 and 45. Significantly increased hemoglobin concentrations were also observed in the 1.92 bl/s group on days 23 and 45. In contrast, values of mean corpuscular volume were significantly lower in the 1.92 bl/s group than in the other groups on day 45. Nitroblue-tetrazolium-positive cells and lysozyme and superoxidase dismutase activities in the plasma increased significantly with increasing training intensity on days 23 and 45. Antibacterial activities were significantly increased in the trained groups compared with the control group on day 23; significantly elevated alkaline phosphatase activity was observed in the 1.92 bl/s groups on day 45. Therefore, training intensities of 0.66 and 1.92 bl/s enhanced the blood oxygen-carrying capability and plasma immune parameters of juvenile tinfoil barbs.

    Here we analyze the outcomes of unlimited access to a low-energy (LE) diet in dams and their offspring. At 3 weeks' gestation, pregnant Wistar rats were divided into two groups: (1) the control group received a normoenergetic diet; and (2) the experimental group received the LE diet. In dams, lactation outcomes, food intake, body weight, plasma IGF-1, prealbumin, transferrin and retinol-binding protein levels were evaluated; in offspring, biometric and biochemical parameters and food intake were evaluated. No differences were observed during pregnancy. However, after lactation, dams that received the LE diet demonstrated significant reductions in body weight (P<0.05), plasma IGF-1 (P=0.01), prealbumin and visceral fat (P<0.001). Pups born to dams that received the LE diet demonstrated reduced body length and weight at weaning (P<0.001) and were lighter than the control animals at the end of the experimental period. Pups also demonstrated reduced plasma, low-density lipoprotein (P=0.04), triglycerides (P=0.002) and glucose levels (P<0.05), and differences were noted in visceral fat. These results indicate that feeding dams with LE diet during the reproductive period induces acute malnutrition and impairs the growth and development of offspring, as well as certain metabolic parameters.

    To determine whether or not there was a significant difference between the methods of centrifugation (CF) and multiple-pass hemoconcentration (MPH) of the residual cardiopulmonary-bypass volume in relation to biochemical measurements and patient outcomes. Prospective, randomized, and controlled. Conducted at a western Canadian tertiary care hospital. Consisted of 61 consecutive male and female patients from ages 40 to 80 who were scheduled for cardiac surgery with cardiopulmonary bypass. Either the centrifugation or multiple-pass hemoconcentration method was used to process the residual blood from the cardiopulmonary bypass circuit. The 12-hour postoperative levels of serum hemoglobin were not significantly different in the centrifugation group as compared to the multiple-pass hemoconcentration group. However, the serum levels of total protein and albumin were significantly higher in the multiple-pass hemoconcentration group as compared to the centrifugation group. Additionally, after 12-hours postoperatively, the serum fibrinogen and platelet counts were significantly higher in the multiple-pass hemoconcentration group as compared to those of the centrifugation group. The allogeneic product transfusion index and the chest-tube blood drainage indices were lower in the multiple-pass hemoconcentration group as compared to the centrifugation group. Although the CF method provided a product in a shorter turnaround time, with consistent clearance of heparin, the MPH method trended towards enhanced biochemical and clinical patient outcomes over the 12-hour postoperative period.

    Full Text Available Of highest biological value are natural concentrates of optimally combined substances produced by nature. One of food supplements of this kind is dietary Spirulina produced by the Tianshi firm (China. It is a most rationally balanced food supplement of a high biological value; it satisfies the needs of the whole body, including its immune system. The aim of the current work was to assess the effect of the multicomponent natural food supplement Spirulina on the physical development, blood morphological, biochemical picture and immune function of sportsmen. Materials and Methods: The study cohort comprised 12 high performance sportsmen (age 20-22 years. They were using tablets of Spirulina, a dietary product for 14 days. Physical development was determined with the aid of standard methods. The general blood picture was analyzed with the aid of a Micros-60 hematological analyzer (company ABX DIAGNOSTICS, France. Lymphocytes and their subsets were analysed by flow cytometery (FACSCalibur, Becton Dickinson Immunocytometry Systems (BDIS, USA and the absolute and percentage values were calculated. To evaluate immune function lymphocyte blasttransformation response to mitogens was studied. Results: Investigations carried out on endurance-training sportsmen showed that a 14-d administration of Spirulina exerted a positive effect on blood morphological composition indices and its biochemical changes. The results of our study confirm the positive effect of Spirulina food supplement on the quantitative parameters of immune system. Part of the study cohort after weeks showed a tendency of normalizing CD3 , CD3 CD4 lympocite count: positive changes were still present two weeks following the interruption of Spirulina intake

    The present study was conducted to assess the role played by some factors including age, residence location, diet, hypertension and job pattern, as incidental factors in the atherogenic process, on the lipid, lipoprotein, homocysteine, vitamin B 12 and folic acid in apparently healthy Egyptian males. Sera from one hundred and forty six apparently healthy male volunteers were analyzed for total cholesterol, triglycerides, high density Iipoproteins cholesterol (HDL-c), low density lipoproteins cholesterol (LDL-c), apolipoprotein A. (Apo At), apolipoprotein B ( Apo B ) and homocysteine, in addition to vitamin B I2 and folic acid. Data from the present study showed that middle aged individuals (over 40 years), urban volunteers, butter users, volunteers experiencing mental work and hypertensives experienced increased lipid fractions when compared to their counterparts. The data also showed the lack of an effect of the previous factors on serum homocysteine, folic acid or vitamin B 12 . In view of the previous findings, it may be concluded that factors such as: age, urban residence, butter consumption, hypertension and intellectual work may contribute to the etiology of atherosclerosis through their impact on serum lipid fractions. Serum homocysteine and related vitamins B 12 and folic acid seem to be unmodified by these factors

    The increased production of urban sewage sludge requires alternative methods for final disposal. A very promising choice is the use of sewage sludge as a fertilizer in agriculture, since it is rich in organic matter, macro and micronutrients. However, urban sewage sludge may contain toxic substances that may cause deleterious effects on the biota, water and soil, and consequently on humans. There is a lack of studies evaluating how safe the consumption of food cultivated in soils containing urban sewage sludge is. Thus, the aim of this paper was to evaluate biochemical and redox parameters in rats fed with corn produced in a soil treated with urban sewage sludge for a long term. For these experiments, maize plants were grown in soil amended with sewage sludge (rates of 5, 10 and 20 t/ha) or not (control). Four different diets were prepared with the corn grains produced in the field experiment, and rats were fed with these diets for 1, 2, 4, 8 and 12 weeks. Biochemical parameters (glucose, total cholesterol and fractions, triglycerides, aspartate aminotransferase and alanine aminotransferase) as well the redox state biomarkers such as reduced glutathione (GSH), malondialdehyde (MDA), catalase, glutathione peroxidase and butyrylcholinesterase (BuChE) were assessed. Our results show no differences in the biomarkers over 1 or 2 weeks. However, at 4 weeks BuChE activity was inhibited in rats fed with corn grown in soil amended with sewage sludge (5, 10 and 20 t/ha), while MDA levels increased. Furthermore, prolonged exposure to corn cultivated in the highest amount per hectare of sewage sludge (8 and 12 weeks) was associated with an increase in MDA levels and a decrease in GSH levels, respectively. Our findings add new evidence of the risks of consuming food grown with urban sewage sludge. However, considering that the amount and type of toxic substances present in urban sewage sludge varies considerably among different sampling areas, further studies are needed to

    Africa is rich in a wide range of flora that are exploited as herbal medicines and remedies. Several diseases such as diabetes, diarrhea, dysentery and jaundice have been successfully managed using herbal medicines. Herbal decoctions or concoctions have been used as pain killers, antibiotics, and hematinics. This study evaluated the hematopoietic and biochemical properties of the stem bark of Sterculia setigera Del. in Wistar rats. Results showed that S. setigera decoction has copiously high tannin and cardiac glycoside levels. Ingestion of the decoction by rats over a 16-day period significantly ( P bark of S. setigera as a hematinic by traditional medical practitioners and show its relative safety. Further experiments are needed to evaluate its safety.

    We investigated effects of dietary administration of stinging nettle (Urtica dioica) on growth performance, biochemical, hematological and immunological parameters in juvenile and adult Victoria Labeo (Labeo victorianus) against Aeromonas hydrophila. Fish were divided into 4 groups and fed for 4 and 16 weeks with 0%, 1%, 2% and 5% of U. dioica incorporated into the diet. Use of U. dioica in the diet resulted in improved biochemical, hematological and immunological parameters. Among the biochemical parameters; plasma cortisol, glucose, triglyceride and cholesterol decreased while total protein and albumin in fish increased with increasing dietary inclusion of U. dioica. Among the haematology parameters: red blood cell (RBC), white blood cell (WBC) counts, haematocrit (Htc), mean cell haemoglobin (MCH), mean cell haemoglobin concentration (MCHC) and netrophiles increased with increasing dietary inclusion levels of U. dioica, some depending on the fish age. Serum immunoglobulins, lysozyme activity and respiratory burst were the main immunological parameters in the adult and juvenile L. victorianus measured and they all increased with increasing herbal inclusion of U. dioica in the diet. Dietary incorporation of U. dioica at 5% showed significantly higher relative percentage survival (up to 95%) against A. hydrophila. The current results demonstrate that using U. dioica can stimulate fish immunity and make L. victorianus more resistant to bacterial infection (A. hydrophila). Copyright © 2015 Elsevier Ltd.

    Salt is widely used to melt snow on roads especially in mountain regions. Whether as rock salt or aerosols, spread or sprayed over road surfaces, salt may result in increased salt concentrations in soils, which, in turn, affect natural vegetation, especially tree seedlings already subjected to various other types of abiotic stress. The authors investigated the effects of salt treatment-related stress on seedling growth and certain biochemical parameters in Quercus robur to determine ion concentrations in root tips. Seedlings growing in a quartz sand/vermiculite mixture were subjected to NaCl concentrations of 0, 50, or 100 mM for 5 weeks. The results showed that high NaCl concentrations caused a marked reduction in total leaf biomass 55 and 75% for 50 and 100 mM treatments, respectively, in dry weight of stems (84%) and roots (175%) for 100 mM treatment and modified root architecture, whereas no changes appeared in leaf number. A non-significant decrease in relative water content, with changes in ion balance was recorded. Comparison of stressed to control plants show an increase in sodium (3.5-8-fold), potassium (0.6-fold), and chloride (9.5-14-fold) concentrations in the root tips while the K + /Na + ratio decreased. In taproots, no significant biochemical differences were observed between the salt-treated and the control plants for acid invertase activity, reducing sugars, sucrose, or soluble protein contents. The significance of ion and sugar accumulations in relation to osmotic adjustment and the ability of oak seedlings to cope with salt stress are discussed.

    Lead is one of the common toxic materials widely occurring in the Nigerian environment. Even with the change to unleaded petrol, other significant sources still remain to be addressed. The deleterious impact of lead on human health, is well documented. The effects range from attention-grabbing mass mortality - as happened in Zamfara State recently, to no less serious but grossly neglected neurocognitive and neurodevelopmental effects, including lowered intelligence quotient scores. All these impacts are most serious in children, especially fetuses who receive their burden from their mothers. Ninety percent of lead in most adults resides in the bones with a half-life measured in decades. Therefore, fetuses and breast-fed children in this generation will remain seriously at risk of exposure to damaging lead levels no matter the efforts to rid our external environment of lead in the years to come. In this work, we have investigated the correlation between Blood Lead Levels (BLL) and up to 35 physiological and biochemical parameters of nutritional importance in 62 women of child-bearing age from lIe-lfe, Nigeria. BLL was determined in venous blood using Inductively- coupled plasma Mass Spectrometry. Our results show that BLL significantly correlates with Packed Cell Volume (PCV), Creatine Clearance, and the ratio of Low-density Lipids to High density Lipids in these women. When the subjects were stratified into different Nutritional Status group based on their Body Mass Index, significant correlation was found between BLL and Age but only in Obese subjects.

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

    This paper examines the effects of gluten-free bread enriched with functional ingredients (milk powder, poppy, sunflower and pumpkin seeds, egg yolk, carum, hazel nuts and amaranth) on the morphological and biochemical parameters and antioxidant status of rats serum. Rats were provided test diets--gluten-free breads and water ad libitum. After 14 days, the animals were weighed and killed. A hazel nut-amaranth bread diet significantly increased the level of thrombocytes when compared to control bread. A mixed bread diet significantly decreased cholesterol levels in rats. All fortified breads decreased triglyceride levels and alanine transaminase activity and caused an increase in antiradical activity of the serum. In rats fed with poppy-milk bread, milk-seed bread and mixed bread, a marked decrease in superoxide dismutase activity was found. Enriched breads reduced the levels of triglyceride and improved the antiradical properties of serum, although the physiological relevance of this needs to be confirmed by human studies.

    Full Text Available The aim of this report was to study the biochemical parameters in sheep blood under conditions of various intensities of parasitic infection with Strongyloides papillosus, as well as after therapy with albendazole (ABZ. Investigations were performed on sheep of the Würtemberg race (n = 30 in which were detected mild, moderate and high intensities of parasitic infection with S. papillosus. The control group (n = 10 was composed of sheep negative to parasitic infections. The degree and type of changes were monitored by determining the concentrations of glucose, total proteins, albumin, A/G ratio, AST, urea, total bilirubin, calcium, phosphorus, total LDH activity and isoenzymatic LDH1-5 distributions. On the basis of the obtained results, we determined, through isoenzymatic LDH distribution, that during parasitic infection with S. papillosus, there is ongoing damage to the liver, heart muscle and lung, while after therapy with ABZ, the liver suffers the most damage. The concentration of glucose, total proteins and albumin fell linearly with the rise in the intensity of parasitic infection (p0.05 and phosphorus (p<0.05 also fall linearly with the rise of the intesity of the parasitic infection. The trend in the concentration fall of these macroelements, continues also after treatment with albendazole (p<0.001. Having in mind our previous studies in the field of oxidative stress and phenomena lying behind these changes, we strongly recommend that in antiparasitic treatment protocols, beside antihelminthics, compounds with antioxidative properties should also be used.

Experimental treatments consisted of feeding a corn-soy basal diet alone, or with graded levels of sugar syrup in increments of 5%, 10% and 15%. All starter diets were isonitrogenous and isocaloric. Body weight gain and efficiency of feed utilization of chicks fed the control diet alone were not significantly (P < 0.05 different from chicks fed diets supplemented with either 5% or 15% sugar syrup. Supplementation of sugar syrup to broiler diets had no significant effect on blood glucose, creatinine, total protein, or liver enzymes. Adding 5% sugar syrup to broiler rations significantly decreased blood cholesterol and triglycerides in chickens fed the sugar syrup diet compared with birds fed the control diet. In conclusion, the results shows sugar syrup can be used in poultry ration to replace part of the corn as a source of energy. These results allowed the authors to recommend the safe usage of sugar syrup in broiler rations.

    This study evaluated preclinical and clinical safety of marshmallow ( Althaea officinalis L.) extract as a naturopathic medicine in common carp deliberately infected with Aeromonas hydrophila . The fish were fed 0 (control), 2.50, 5.00 and 10.00 g of marshmallow extract for 60 days in a preclinical experiment and then, challenged with A. hydrophila for a 10-day experiment. Significant increases were observed in aspartate aminotransferase (AST), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), creatine phosphokinase (CPK) activities and plasma creatinine levels in fish fed 10 g marshmallow extract per kg feed. However, alanine aminotransferase (ALT) significantly decreased on day 60. The fish fed 2.50 g marshmallow extract per kg feed indicated increased levels of total protein and globulin. There were no significant changes in albumin levels ( p > 0.05). 2.50 and 5.00 g marshmallow significantly decreased triglyceride and cholesterol levels and increased glucose levels ( p Marshmallow extract at 5.00 and 10.00 g can adjust plasma biochemical parameters in fish challenged with A. hydrophila . The results of preclinical studies and pharmaceutical toxicity of marshmallow extract revealed that dietary levels lower than 5.00 g were safe and effective. The results of this clinical study demonstrated that marshmallow extract (5.00 g kg -1 feed) can protect fish against A. hydrophila .

    Chronic hyperglycemia in diabetes is a major causative factor of free radical generation which further leads to many secondary diabetic complications via the damage to cellular proteins, membrane lipids, and nucleic acids. Zinc is an essential trace element in all living systems and plays a structural role in many proteins and enzymes. Somatostatin is known to have inhibitory effects on various gastrointestinal functions. Therefore, we determined somatostatin protein production and secretion levels, and biochemical and light microscopical changes following zinc supplementation in the gastrointestinal tract of streptozotocin (STZ)-diabetic rats. The animals were divided into four groups: Group I: control (untreated) animals; Group II: control animals given zinc sulfate; Group III: diabetic animals; and Group IV: diabetic animals given zinc sulfate. Zinc sulfate was given to the animals by gavage at a daily dose of 100 mg/kg body weight for 60 days. Diabetes was induced by intraperitoneal (i.p.) injection of STZ in a single dose of 65 mg/kg. For histological studies, stomach and duodenum tissues were fixed in Bouin solution and sections stained with Masson’s trichrome and Periodic-Acid-Schiff. Tissue homogenates were used for protein, lipid peroxidation (LPO), glutathione (GSH), and nonenzymatic glycosylation (NEG) analyses. Zinc supplementation to the STZ-diabetic rats revealed the protective effect of zinc on these parameters. Zinc supplementation may contribute to prevent at least some complications of diabetes mellitus

    Introduction Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disorder associated with ovulatory dysfunction. Presently, little is known about the primary factors that initiate PCOS. Chamomile flowers are used in alternative medicine for its anti-spasmolytic and anti-inflammatory effects. Antispasmodic properties of chamomile ease menstrual cramps and lessen the possibility of premature labor. This medicinal herb also stimulates menstruation. In this study, we evaluated the effects of Chamomile alcoholic-extract on the biochemical and clinical parameters in a rat model of PCOS. Materials and Methods Estrous cyclicity of 30 virgin adult cycling rats was monitored by vaginal smears obtained between 0800 and 1200 hours. After about 4 days, each rat received an i.m. injection of Estradiol Valerate (Aburaihan Co., Iran), 2 mg in 0.2 ml of corn oil, to induce PCO. Corn oil was injected to the rats in the control group. All the rats in the experimental group were evaluated for follicular cysts 60 days after the injection. Rats with PCOS were treated by multiple doses (25, 50, 75 mg/kg) of intraperitoneal injections of Chamomile alcoholic-extract for ten days. The data were statistically analyzed at a significance level of pChamomile can decrease the signs of PCOS in the ovarian tissue and help LH secretion in rats (pChamomile. PMID:23926485

    The conventional Biochemical Oxygen Demand (BOD) method takes five days to analyze samples. A microbial fuel cell (MFC) may be an alternate tool for rapid BOD determination in water. However, a MFC biosensor for continuous BOD measurements of water samples is still unavailable. In this study, a MFC biosensor inoculated with known mixed cultures was used to determine the BOD concentration. Effects of important parameters on establishing a calibration curve between the BOD concentration and output signal from the MFC were evaluated. The results indicate monosaccharides were good fuel, and methionine, phenylalanine, and ethanol were poor fuels for electricity generation by the MFC. Ions in the influent did not significantly affect the MFC performance. CN(-) in the influent could alleviate the effect of antagonistic electron acceptors on the MFC performance. The regression equation for BOD concentration and current density of the biosensor was y = 0.0145x + 0.3317. It was adopted to measure accurately and continuously the BOD concentration in actual water samples at an acceptable error margin. These results clearly show the developed MFC biosensor has great potential as an alternative BOD sensing device for online measurements of wastewater BOD.

    Reactive oxygen species (ROS) generated from UV-B radiation have the capacity to cause oxidative decomposition which leads to the formation of toxic components as well as lipid peroxidation. Considering this fact, the present study was performed to evaluate the effect of a cream (O/W) containing the essential oil of Calendula officinalis on biochemical parameters of the skin of albino rats against UV-B radiation. The fingerprint analysis of Calendula essential oil was performed by HPLC with special reference to 1,8-cineole and α-pinene. The results indicated that the treatment with creams containing 4% and 5% of Calendula essential oil caused a significant decrease in the malonyldialdehyde level, whereas the levels of catalase, glutathione, superoxide dismutase, ascorbic acid, and the total protein level were significantly increased after 1 month of daily irradiation and treatment when compared to untreated control groups. The results suggest that the cutaneous application of the essential oil of Calendula prevents UV-B-induced alterations in the level of antioxidants in skin tissue. PMID:23008814

    The objective of this research was to evaluate the biochemical and hormonal parameters of Santa Inês sheep that received diets with different levels of guava agro-industrial waste (GAW). Forty non-castrated male animals of the Santa Inês breed were used, with an average initial weight of 21.3 ± 2.6 kg, and an average age of 120 days. The animals were distributed in a completely randomized design, with five treatments and eight replicates, and fed with increasing GAW levels replacing hay (0.0, 7.5, 15.0, 22.5 and 30.0%). After the beginning of the diet period, blood samples were collected every 2 weeks approximately 3 h after feeding. Cholesterol concentration had a significant effect (P < 0.01) with the inclusion of GAW. The animals that ingested the control diet had the highest concentrations of cholesterol. T3 and T4 hormones showed a significant difference (P < 0.01) among the treatments, i.e. the animals that ingested the control diet had the lowest concentrations of these hormones. We concluded that the inclusion of GAW in up to 30% decreases the concentration of cholesterol and increases the concentrations of T3 and T4 in the blood, aiding the metabolism of the animals.

    This study was conducted at El-Khaer and El-Barka project, El-Salhya town, El-Sharkia governorate, Egypt. Forty Friesian calves with average body weight of 320 kg were used in this research and divided into four experimental groups. Olive pulp was incorporated in the four groups R1, R2, R3 and R4 at rates of 0, 10, 20 and 30% in calves feeds to replace similar amounts of maize, respectively. Diets were fed for 60 days then body weight was recorded at the beginning and at the end of the experiment and the daily weight gain was calculated for each animal. Blood samples were taken from each animal at the end of the experiment to determine some blood biochemical parameters. The results indicated that the maximum average daily body weight gain was achieved by Friesian calves in R4 (1.38 kg/d). Non-significant changes were recorded in total protein, AST, T4 and lipids but the increase in calcium, phosphorus, urea and creatinine levels was within the normal levels. Feed efficiency was highest in R4 (30% olive pulp) and the feed cost for total weight gain was the lowest value in the same group. It could be recommended to use olive pulp in ruminant ration at 30%, especially when the traditional feed grains are not available and feed costs would be reduced

    A large proportion of South African feedlot cattle are crossbreds of Brahman (BrX, Bos indicus), and Simmental (SiX, Bos taurus). A sample of 20 grain fed bulls from each of these crossbreeds was used to compare meat quality with that of the small frame indigenous Nguni (NgX, Sanga) by evaluating a variety of biochemical and genetic parameters previously shown to be associated with meat tenderness. Shear force values were generally high (5.6kg average at 14days post mortem), with SiX animals higher than BrX or NgX (P=0.051) despite higher calpastatin:calpain ratio in BrX (P<0.05). Calpain activity and cold shortening were both correlated with tenderness for all classes. The sample size was too small to accurately estimate genotypic effects of previously published markers in the CAST and CAPN1 genes, but the allele frequencies suggest that only modest progress would be possible in these South African crossbreds using these markers.

    The purpose of this study was to investigate the effect of diurnal variation on biochemical results of first trimester aneuploidy screening test. A total of 2725 singleton pregnant female, who had normal fetal nuchal translucency (NT) thickness, were included in the study during this period. Individuals were divided into two groups according to the sampling time (morning group: 09:00-11:00 am and afternoon group: 02:00-04:00 pm). Hormonal parameters (free-beta human chorionic gonadotropin [free β-hCG] and pregnancy-associated plasma protein-A [PAPP-A] multiples of median [MoM] levels) of first trimester (11(+0)-13(+6) weeks) combined aneuploidy screening test were compared between morning and afternoon groups. PAPP-A MoM levels were significantly lower in the afternoon group when compared to the morning group (p = 0.001), whereas free β-hCG MoM levels were similar in the both groups (p = 0.392). Rate of high risk for Down syndrome (Combine risk >1/300) and amniocentesis ratio were found higher in the afternoon group than morning group, but there were no difference between groups for the number of fetuses with Down syndrome. Receiving the venous blood sample for first trimester aneuploidy screening test in the afternoon causes low PAPP-A MoM levels.

    To determine whether the use of the subdermal contraceptive implant releasing etonogestrel (Implanon) affects serum hormonal and biochemical indices. Seventy women with a mean age of 28.5+/-3.4 years were enrolled into this prospective observational study. After placement of an Implanon rod, they were followed-up for three years. Baseline and end-of-study values of serum low-density lipoprotein (LDL), high-density lipoprotein (HDL), cholesterol, triglycerides, fasting glucose, blood urea nitrogen (BUN), creatinine, SGOT, SGPT, follicle stimulating hormone (FSH), luteinizing hormone (LH), oestradiol, free 3,5,3'-tri-iodothyronine (fT3), free thyroxine (fT4), thyroid stimulating hormone (TSH), and prolactine (PRL) were compared using Student's t-test. There was no failure of contraception during the three year period. No statistically significant differences were observed between the initial and final levels of fasting blood glucose, BUN, SGOT, SGPT, LDL, HDL, E2, FSH, LH, fT3, fT4 and TSH (p>0.05), but the increase in PRL, cholesterol and triglycerides, and the decrease in creatinine levels at the end of three years were statistically significant (p<0.05) although the values were still within normal ranges. Our findings confirm data from the literature according to which Implanon does not affect meaningfully reproductive hormonal parameters, thyroid function, hepatic and renal functions, and glucose metabolism. However, further studies are needed to elucidate lipid metabolism changes.

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

    Full Text Available Abstract Background Previous studies have shown the short-term or intermediate-term practice of yoga to be useful for ameliorating several mental disorders and psychosomatic disorders. However, little is known about the long-term influences of yoga on the mental state or stress-related biochemical indices. If yoga training has a stress-reduction effect and also improves an individual's mental states for a long time, long-term yoga practitioners may have a better mental state and lower stress-related biochemical indices in comparison to non-experienced participants. This study simultaneously examined the differences in mental states and urinary stress-related biochemical indices between long-term yoga practitioners and non-experienced participants. Methods The participants were 38 healthy females with more than 2 years of experience with yoga (long-term yoga group and 37 age-matched healthy females who had not participated in yoga (control group. Their mental states were assessed using the Profile of Mood States (POMS questionnaire. The level of cortisol, 8-hydroxydeoxyguanosine (8-OHdG and biopyrrin in urine were used as stress-related biochemical indices. Results The average self-rated mental disturbance, tension-anxiety, anger-hostility, and fatigue scores of the long-term yoga group were lower than those of the control group. There was a trend toward a higher vigor score in the long-term yoga group than that in the control group. There were no significant differences in the scores for depression and confusion in the POMS between the two groups. The urine 8-OHdG concentration showed a trend toward to being lower in the long-term yoga group in comparison to the control group. There were no significant differences in the levels of urine biopyrrin or cortisol. Conclusions The present findings suggest that long-term yoga training can reduce the scores related to mental health indicators such as self-rated anxiety, anger, and fatigue.

    Full Text Available In this experimental prospective study, we aimed to analyze the effect of transient scrotal hyperthermia on the male reproductive organs, from the perspective of sperm parameters, semen plasma biochemical markers, and oxidative stress, to evaluate whether different frequencies of heat exposure cause different degrees of damage to spermatogenesis. Two groups of volunteers (10 per group received testicular warming in a 43°C water bath 10 times, for 30 min each time: group 1: 10 consecutive days; group 2: once every 3 days. Sperm parameters, epididymis and accessory sex gland function, semen plasma oxidative stress and serum sex hormones were tested before treatment and in the 16-week recovery period after treatment. At last, we found an obvious reversible decrease in sperm concentration (P = 0.005 for Group 1 and P= 0.008 for Group 2 when the minimums were compared with baseline levels, the same below, motility (P = 0.009 and 0.021, respectively, the hypoosmotic swelling test score (P = 0.007 and 0.008, respectively, total acrosin activity (P = 0.018 and 0.009, respectively, and an increase in the seminal plasma malondialdehyde concentration (P = 0.005 and 0.017, respectively. The decrease of sperm concentration was greater for Group 2 than for Group 1 (P = 0.031. We concluded that transient scrotal hyperthermia seriously, but reversibly, negatively affected the spermatogenesis, oxidative stress may be involved in this process. In addition, intermittent heat exposure more seriously suppresses the spermatogenesis compared to consecutive heat exposure. This may be indicative for clinical infertility etiology analysis and the design of contraceptive methods based on heat stress.

    Full Text Available Background: In this study, the potential side effects of Khaya grandifolola (KG and Enatia chlorantha (EC were investigated on liver function and hematological parameters of Swiss albino mice infected with malaria. Method: This study was carried out in part in the Department of Biochemistry, Kwara State University, Malete, and in part in the Department of Biochemistry, Faculty of Life Sciences, University of Ilorin, Ilorin, Nigeria, 2016. Aqueous extracts of both KG and EC were screened for the presence of some phytochemicals using gas chromatography-mass spectrometry. Five groups of eight animals each were used. Group A was administered with only distilled water. Group B was administered with 50 mg/kg body weight of artemisinin-based combination therapy (ACT. Groups C, D, and E were treated with 400 mg/kg body weight of KG, EC and KG-EC combination, respectively. After 28 d, the animals were sacrificed for biochemical analysis. Results: The levels of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and bilirubin activities were not significantly different (P˂0.05 in all the extract treated animal groups as compared to ACT. However, there was increase in the concentrations of ATL and total bilirubin when compared with that of controls. There was no significant difference (P˂0.05 among Hb, RBC, PCV, WBC, lymphocytes, and platelets compared with ACT. However, they increased as compared to the control groups. Conclusion: The aqueous bark extracts of KG and EC either in single or in combined form resulted in hepatotoxicity compared to controls. They also have deleterious effects on hematological parameters of the Swiss mice following administration.

    Chronic obstructive pulmonary disease (COPD) is an airway inflammatory disease caused by inhalation of toxic particles, mainly cigarette smoking, and now is accepted as a disease associated with systemic characteristics. The aim of this work was to investigate and compare selected biochemical parameters in patients with and without COPD. Observation group consisted of clinically stable patients with COPD (n = 60). The control group was healthy persons from the general population, without COPD, who were divided into two subgroups – smokers (n = 30) and non-smokers (n = 30). Laboratory parameters were investigated by automated clinical chemistry analyzer LISA 200th. Albumin in our measurements showed an average value of 39.55 g.l-1 in the patient population; 38.89 g.l-1 in smokers and in non-smokers group 44.65 g.l-1. The average value of pre-albumin in the group of patients was 0.28 ± 0.28 g.l-1 and 0.30 ± 0.04 g.l-1 in smokers group. The average value of the orosomucoid in patients was about 1.11 ± 0.90 mg.ml-1. In the group of smokers, the mean value of orosomucoid was 0.60 ± 0.13 mg.ml-1. The level of C-reactive protein (CRP) in the patient group reached an average value of 15.31 ± 22.04 mg.l-1, in the group of smokers was 5.18 ± 4.58 mg. l-1. Prognostic inflammatory and nutritional index (PINI) in the group of patients showed a mean value of 4.65 ± 10.77 and 0.026 ± 0.025 in smokers. The results of this work show, that the values of index PINI in COPD patients are significantly higher than in smokers (P COPD.

    Tannic acid (TA) is a polyphenolic compound with a health-promoting potential for humans. It is hypothesised that TA effects on the relative weight of internal organs and biochemical blood indices are modified by dietary protein level in rats. The study involved 72 rats divided into 12 groups fed diets with 10 or 18% of crude protein (CP) and supplemented with 0, 0.25, 0.5, 1, 1.5 or 2% of TA. After 3 weeks of feeding, the relative weight of the caecum was greater in rats fed TA diets, while feeding diets with 10% of CP increased the relative weight of the stomach, small intestine and caecum, but decreased that of kidneys and spleen. Albumin concentration was higher in rats fed 0.25% and 0.5% TA diets than in rats given the 2% TA diets. The 2% TA diets reduced creatine kinase (CK) activity compared to non-supplemented diets and those with 0.5, 1 and 1.5% of TA. Rats fed the 10% CP diets had a higher activity of alkaline phosphatase, amylase, and γ-glutamyltransferase as well as the concentration of iron and cholesterol, but lower that of urea and uric acid. The interaction affected only cholinesterase activity. In conclusion, TA induced caecal hypertrophy and could act as a cardioprotective agent, as demonstrated by reduced CK activity, but these effects were not modified by dietary protein level.

METHODS: This was a cross-sectional study in which 21 therapy-naïve patients with AML were compared with a group of 24 healthy individuals. The following data were analyzed: serum proteins, leucocytes and subgroups, erythrocytes, hematocrit, hemoglobin, platelets, cytokines in peripheral blood mononuclear cells cultures under spontaneous and BCG- or PHA-stimulated conditions, immunoglobulin A, and erythrocytic glutathione. Statistical analysis was performed using SPSS software, considering as significant p-values < 0.05. RESULTS: Serum albumin levels were higher (p < 0.0001 in the control group, as well as all the parameters related to red blood cells (p < 0.0001. For leucocytes and subgroups, no statistical difference was found between the AML and the control groups. For cytokines, the concentrations were significantly higher under spontaneous and BCG-stimulated conditions for TNF-a, IL-6, IL-10, and IFN-? in the control group. Under PHA-stimulated conditions, the concentration was higher (p = 0.002 only for IL-6. No difference was found between the two groups for the other cytokines and for IgA in the saliva. Erythrocytic glutathione was higher (p < 0.0001 in AML patients. CONCLUSIONS: It was possible to characterize the biochemical and immunological profile of pediatric patients with AML, as well as highlight some significant differences in these parameters when comparing with healthy children and adolescents.

This was a cross-sectional study in which 21 therapy-naïve patients with AML were compared with a group of 24 healthy individuals. The following data were analyzed: serum proteins, leucocytes and subgroups, erythrocytes, hematocrit, hemoglobin, platelets, cytokines in peripheral blood mononuclear cells cultures under spontaneous and BCG- or PHA-stimulated conditions, immunoglobulin A, and erythrocytic glutathione. Statistical analysis was performed using SPSS software, considering as significant p-values<0.05. Serum albumin levels were higher (p<0.0001) in the control group, as well as all the parameters related to red blood cells (p<0.0001). For leucocytes and subgroups, no statistical difference was found between the AML and the control groups. For cytokines, the concentrations were significantly higher under spontaneous and BCG-stimulated conditions for TNF-α, IL-6, IL-10, and IFN-γ in the control group. Under PHA-stimulated conditions, the concentration was higher (p=0.002) only for IL-6. No difference was found between the two groups for the other cytokines and for IgA in the saliva. Erythrocytic glutathione was higher (p<0.0001) in AML patients. It was possible to characterize the biochemical and immunological profile of pediatric patients with AML, as well as highlight some significant differences in these parameters when comparing with healthy children and adolescents.

    To investigate: 1) acanthocytosis and presence of acanthocytes in peritoneal fluid as a diagnostic marker for hemangiosarcoma (HSA) in dogs with non-traumatic hemoabdomen; and 2) the association between other erythrocyte, biochemical, and hematologic abnormalities as a mean of differentiating HSA from other disease. Prospective double-blinded cohort study. Dogs (n = 40) with non-traumatic hemoabdomen. Dogs diagnosed with hemoabdomen (January 2012 to May 2013) had cytologic evaluation of abdominal effusion and peripheral blood smears. Peripheral blood CBC, PT, and aPTT, as well as blood and effusion acanthocytes, keratocytes, schistocytes, lactate, glucose, PCV, and TP results were compared using the paired t-test or Fisher's exact test. Based on histologic confirmation of HSA, dogs were divided into 2 groups (HSA, non-HSA) and variables compared. There was no significant difference in erythrocyte morphology in abdominal effusion or peripheral blood between dogs with HSA or non-HSA related hemoabdomen. Platelet concentration and peripheral blood PCV were significantly lower in the HSA group. A reliable preoperative biochemical or cytologic test to differentiate between HSA and non-HSA related hemoabdomen was not identified. © Copyright 2015 by The American College of Veterinary Surgeons.

    Bifenthrin (BIF) is a pyrethroid (PYR) insecticide. The target point for PYR's toxic action are voltage sensitive sodium channels in the central nervous system (CNS). Intoxication with PYRs results in motor activity impairment and death in insects. Although PYRs are considered to be safe for mammals, there were numerous cases of pyrethroid poisoning in humans, animals and pets described. The general population is chronically exposed to PYRs via grain products, dust and indoor air. Therefore new questions arise: whether PYRs act in a dose-additive fashion in the course of subacute poisoning, are there other target organs (but brain) for BIF and if there is one common mechanism of its' toxic action in different organs. The objective of this work was to characterize the effect of BIF at the doses of 4 or 8 mg/kg injected intraperitoneally (i.p.) daily for 28 consecutive days on memory and motor activity, hematological, biochemical and histopathological parameters in mice. BIF at the doses of 8 mg/kg or 4 mg/kg of body mass was administered i.p. daily to the mice for 28 consecutive days. Motor function was measured on day 1, 7, 14 and 28 and memory retention was tested in a passive avoidance task on day 2, 7, 14 and 28. BIF significantly impaired memory retention on day 2. BIF decreased locomotor activity at every stage of the experiment in a single dose depending manner. No behavioral cumulative effect was observed. Subacute poisoning with the higher dose of BIF caused anaemia, elevated white blood cell count (WBC), elevated alanine transaminase (ALT), superoxide dismuthase (SOD), and decreased glutathione peroxidase (GPx) activity. Lymphocyte infiltrates were visualized in the livers. subacute poisoning with BIF decreases locomotor activity in a single dose proportionate manner. BIF damages also the liver and alters blood morphology. The possible common mechanism of these effects can be oxidative stress.

    Consumption of soft drinks, in particular carbonated beverages, has markedly increased in the last two to three decades. In fact, the carbonated beverages are the most popular refreshments among most of the world's population. The aim of this study was to assess the body weight gains and analyze some biochemical and hematological parameters in male and female Balb/c mice. Animals were provided with diluted coca cola (fructose rich soft drink) for 6 weeks and were matched against corresponding control animals. The control animals were maintained on tap water ad libitum and coca cola was diluted v/v by tap water. The results revealed that the percentages of body weight gains of male and female control animals were significantly higher than the corresponding mice provided with coca cola. Hemoglobin content (Hb, g/100ml blood), erythrocytes (RBCs), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), leucocytes (WBCs), granulocytes and blood platelet counts were significantly decreased in the groups of mice treated with the soft drink, compared to the control groups. However, significant increases were observed in lymphocytes in the treated groups. Consumption of the soft drink (coca cola) in both male and female animal groups exhibited significant increases of total cholesterol, triglycerides, low density lipoprotein-c and atherogenic index. Levels of serum calcium significantly decreased in both male and female treated mice than the corresponding control groups. Consumption of coca cola did not affect the levels of T3. This study suggests that consumption of high fructose soft drink may lead to many health problems

    The aim of the present study was to evaluate the effect of the association of whole body vibration (WBV) exercise with an aqueous extract of coriander on the biodistribution of the radiopharmaceutical sodium pertechnetate, on the concentration of some plasma biomarker, on the feed intake, on the body mass, and on the stool consistency in rats. Rats were divided in four groups and submitted to different treatments for 40 days. The control group (CON) received deionized water. The group treated with coriander (COR) received the extract of coriander. The rats that were exposed to WBV exercises (WBV-E) also received deionized water. A group of animals received coriander and was exposed to WBV (COR + WBV-E). We found in testis a decrease (0.13 ± 0.01 to 0.06 ± 0.03) of the percentages of injected radioactivity per gram (%ATI/g) in the WBV-E in comparison with the COR. There is no significant alteration on the concentrations of the plasma biomarkers. The feed intake showed a statistically significant increase in WBV-E. No significant difference on the body mass was found. The stool analysis showed a statistical difference on the consistency between COR (hard and dry, darker) and all the other groups (normal). In conclusion, it was verified that possible modifications in some biochemical/physiological parameters of the rats submitted to WBV exercise would be capable to increase the feed intake without changing the body mass, and normalizing the stool consistency altered by the coriander supplementation. Further studies are needed to try to understand better the biological effects involving the association of WBV exercise and coriander. © 2017 The Author(s).

    Organophosphorus (OP) insecticides constitute one of the most widely used classes of pesticides being employed for both agricultural and landscape pest control. The purpose of this study was to investigate the effect of dimethoate (DM), an organophosphorus insecticide, on some biochemical and histopathological parameters in liver of adult male guinea pigs as well as the possible role of Withania somnifera extract in attenuation of DM-induced hepatotoxicity. The animals were divided randomly into 5 groups and kept at 5 animals per group in an environmentally controlled condition with free access to food and water ad libitum. The first group was served as a control group and administered with olive oil orally; the group II received aqueous extract of W. somnifera (100 mg kg(-1) b.wt.) orally, group III, IV and V was administered with DM (14 mg kg(-1); 1/25LD50) for 21 days orally. Group IV and V received 100 mg kg(-1) of W. somnifera extract and silymarin, respectively half hour before DM administration for 21 days. DM caused a statistically significant increase in the serum level of liver enzymes (AST, ALT, ALP) when compared to control animals, whereas, W. somnifera and silymarin pre-treatment to the DM-intoxicated animals resulted in a significant normalization of the enzymes activities. On the other hand W. somnifera extract reduced the incidence of histopathological changes such as cytoplasmic vacuolization and degeneration in nuclei, rupture of epithelia lining the central vein, widened sinusoidal space and lymphocyte infiltration induced by DM treatment in guinea pigs. In conclusion, the results of this study suggest that W. somnifera aqueous extract could protect the liver against DM-induced oxidative damage.

    Shelf-stable milk could benefit from sensory quality improvement. Current methods of heating cause flavor and nutrient degradation through exposure to overheated thermal exchange surfaces. Rapid heating with microwaves followed by sudden cooling could reduce or eliminate this problem. The objectives for this study were focused on designing and implementing continuous microwave thermal processing of skim fluid milks (white and chocolate) to compare sensory, microbiological, and biochemical parameters with conventionally prepared, indirect UHT milks. All test products were aseptically packaged and stored at ambient temperature for 12 mo. Every 3 mo, samples were taken for microbiological testing, reactive sulfhydryl determinations, active enzyme analysis, instrumental viscosity readings, color measurements, and descriptive sensory evaluation. Microbiological plate counts were negative on all milks at each time point. Enzymatic assays showed that plasmin was inactivated by both heat treatments. 5,5'-dithio-bis(2-nitrobenzoic acid) analysis, a measure of reactive sulfhydryl (-SH-) groups, showed that the initial thiol content was not significantly different between the microwave-processed and UHT-treated milks. However, both heating methods resulted in an increased thiol level compared with conventionally pasteurized milk samples due to the higher temperatures attained. Sulfhydryl oxidase, a milk enzyme that catalyzes disulfide bond formation using a variety of protein substrates, retained activity following microwave processing, and decreased during storage. Viscosity values were essentially equivalent in microwave- and UHT-heated white skim milks. Sensory analyses established that UHT-treated milks were visibly darker, and exhibited higher caramelized and stale/fatty flavors with increased astringency compared with the microwave samples. Sweet aromatic flavor and sweet taste decreased during storage in both UHT and microwave milk products, whereas stale/fatty flavors

    This study was conducted to evaluate the effects of zinc methionine (Zn-Met) supplementation on the performance, egg quality, antioxidant status and some biochemical parameters of blood serum in laying hens from 22 to 34 weeks of age. A total of 120 Hisex Brown laying hens of 22-week-old were randomly allocated into five treatments with six cage replicates for each (four hens/replicate). Dietary treatments consisted of the basal diet with no Zn-Met supplementation (control group) and basal diet supplemented with 25, 50, 75 or 100 mg Zn-Met/kg diet. No significant differences were observed on body weight, body weight gain or feed conversion ratio due to dietary Zn-Met supplementation. However, highly significant impact was observed on daily feed intake. Egg number, egg weight and egg mass were increased in the group fed diet supplemented with the highest level of Zn-Met (100 mg/kg of diet) as compared to other groups. All egg quality traits were statistically (p > .05 or .01) affected as a response to dietary Zn-Met supplementation except egg shape index, shell percentage and yolk index. In comparison with the control group, dietary supplementation of 25, 50, 75 or 100 mg Zn-Met/kg decreased serum triglyceride and LDL-cholesterol levels. Serum cholesterol level was increased with all dietary levels of Zn-Met in comparison with the control group. Dietary Zn-Met supplementation increased the serum content of zinc, where the highest values were recorded with 50 and 100 mg Zn-Met/kg diet. Dietary Zn-Met levels did not affect the antioxidant indices in blood serum except for the activity of copper-zinc superoxide dismutase (Cu-Zn-SOD). The activity of Cu-Zn-SOD was increased with Zn-Met supplementations with no differences among supplemental zinc levels. It is concluded that dietary Zn-Met supplementation reduced serum triglyceride, LDL-cholesterol and increased Zn status and resulted in promoting antioxidant ability of laying hens, and the addition of 100 mg Zn

    The present study was conducted to determine the heavy metal contamination in soil with accumulation in edible parts of plants and their subsequent changes in biochemical constituents due to wastewater irrigation. Though the wastewater contains low levels of the heavy metals (Fe, Mn, Pb, Cd, and Cr), the soil and plant samples show higher values due to accumulation. The trend of metal accumulation in wastewater-irrigated soil is in the order: Fe > Pb > Mn > Cr > Cd. Of the three species Colocasia esculentum, Brassica nigra, and Raphanus sativus that are grown, the order of total heavy metal accumulation in roots is Raphanus sativus > Colocasia esculentum, while in shoots the order is Brassica nigra > Colocasia esculentum > Raphanus sativus. The enrichment factor (EF) of the heavy metals in contaminated soil is in the sequence of Cd (3) > Mn (2.7) > Cr (1.62) > Pb (1.46) > Fe (1.44), while in plants EF varies depending upon the species and plant part. C. esculentum and R. sativus show a higher EF for Cr and Cd. All plants show a high transfer factor (TF > 1) for Cd signifying a high mobility of Cd from soil to plant whereas the TF values for Pb are very low as it is not bioavailable. Results of the biochemical parameters show decrease in total chlorophyll and total amino acid levels in plants and an increase in amounts of soluble sugars, total protein, ascorbic acid, and phenol except B. nigra for protein in plants grown in soil irrigated with wastewater as compared to control site.

    Two schemes of parameter relations, linear relation and non-linear relation are discussed. The linear relation of coupling constants is derived directly from an underlying symmetry of the classical theory and is preserved usually in the quantum theory. The non-linear relation is not derived by a same manner but is derived by more involved way which is intrinsically connected with quantum theory. An underlying symmetry which leads the linear relation is shown to be essential in the non-linear relation too. Some extension is also discussed

    Full Text Available In the present study, the median lethal concentration (LC 50 of neem leaf extract to Cirrhinus mrigala for 24 h was found to be 1.035 g l-l. During the study period, the haematological parameters including Hb, Hct, RBC, MCV, MCH and MCHC levels were significantly decreased in neem leaf extract exposed fish when compared to the control fish whereas WBC count was increased. Similarly, plasma Na+ and Cl- levels were significantly lower and K+ level were significantly higher when compared to the control. In biochemical study, elevated plasma glucose and induced protein levels were noticed. The enzymes, glutamate oxaloacetate transaminase (GOT and glutamate pyruvate transaminase (GPT activities were increased significantly in gill, liver and muscle of treated fish compared to that of their control groups. The results of the present investigation suggest that neem leaf extracts affects the hematological, ionoregulatory, biochemical and enzymological parameters of fish and alterations of these parameters can be useful in environmental biomonitoring of neem based products in freshwater environment.Keywords: Azadirachta indica, Acute toxicity, Cirrhinus mrigala, Haematology, Ion regulation, Biochemical and Enzymological parameters.

    Full Text Available Metabolic syndrome (MS is a multifactorial disease involving inflammatory activity and endothelial dysfunction. The aim of the present study was to evaluate the relationship between the changes in lipoperoxidation, in immunological and biochemical parameters and nitric oxide metabolite (NOx levels in MS patients. Fifty patients with MS (4 males/46 females and 50 controls (3 males/47 females were studied. Compared to control (Mann-Whitney test, MS patients presented higher serum levels (P < 0.05 of fibrinogen: 314 (185-489 vs 262 (188-314 mg/dL, C-reactive protein (CRP: 7.80 (1.10-46.50 vs 0.70 (0.16-5.20 mg/dL, interleukin-6: 3.96 (3.04-28.18 vs 3.33 (2.55-9.63 pg/mL, uric acid: 5.45 (3.15-9.65 vs 3.81 (2.70-5.90 mg/dL, and hydroperoxides: 20,689 (19,076-67,182 vs 18,636 (15,926-19,731 cpm. In contrast, they presented lower (P < 0.05 adiponectin: 7.11 (3.19-18.22 vs 12.31 (9.11-27.27 µg/mL, and NOx levels: 5.69 (2.36-8.18 vs 6.72 (5.14-12.43 µM. NOx was inversely associated (Spearman’s rank correlation with body mass index (r = -0.2858, P = 0.0191, insulin resistance determined by the homeostasis model assessment (r = -0.2530, P = 0.0315, CRP (r = -0.2843, P = 0.0171 and fibrinogen (r = -0.2464, P = 0.0413, and positively correlated with hydroperoxides (r = 0.2506, P = 0.0408. In conclusion, NOx levels are associated with obesity, insulin resistance, oxidative stress, and inflammatory markers. The high uric acid levels together with reactive oxygen species generation may be responsible for the reduced NO levels, which in turn lead to endothelial dysfunction. The elevated plasma chemiluminescence reflecting both increased plasma oxidation and reduced antioxidant capacity may play a role in the MS mechanism.

    Full Text Available ABSTRACT Food Intolerance, is a reaction against food, but not immunological manner, and may be confused with real food allergies. In this study, effects of special weight-loss diet together with an elimination diet on body composition and biochemical parameters of overweight and obese people who were diagnosed with food intolerance were investigated. The study group consists of 20 patients in total who were followed-up and treated in Yorktest Turkey Laboratory; who were diagnosed with food intolerance, and whose BMI was > 26kg/m2. Bloodletting for these patients was executed with Lancet from their fingertips, and the blood drawn from these patients was assessed via enzyme-linked immunosorbent assay (ELİSA method, and food reactions of patients were determined for each food. Biochemical parameters of these patients are routine tests, which are necessary for food intolerance tests, and they are analyzed at Yorktest Turkey Laboratory for two times: before and after elimination diet plus special weight-loss diet. It has been determined that, the most common sensivity is obtained against yeast, egg yolk and white, cranberry, cow’s milk, chicken, lentils and parsley. Anthropometric measurements and biochemical parameters before and after elimination diet plus special weight-loss diet applied to participants, were significantly improved in statistical manner. Due to positive changes in body composition and biochemical parameters obtained through application of special weight-loss diets together with elimination diet applied to fat and obese people, we think that this diet might be used for medical nutrition treatment of obesity as a treatment option.

    To evaluate the usefulness of whole body bone mineral densitometry in the diagnosis of frequent osteopenia of preterm infants by comparison with the wrist radiographs and biochemical parameters. From January 1995 to January 1996, we obtained whole body bone mineral density(BMD) studies using dual energy X-ray absorptiometry(DXA) and wrist radiographs of 39 preterm infants. They were divided into three groups according to birth weight, under 1500g, 1501g to 2000g and above 2000g, and four grades of skeletal change, as seen on wrist radiography, according to the scoring method of Koo et al. Groups of birth weight and grades of skeletal change were then correlated with whole body BMD and biochemical parameters. For comparison, normal data were obtained from 13 infants born at full term. Data were analyzed by one way analysis of variation(ANOVA) and correlation and regression analysis. A p-value of less than 0.05 was considered significant. Whole body BMDs were significantly lower in the more premature and smaller birth weight infants(r=0.77, p=0.0000), and in the higher grade of skeletal change(r-0.5276, p=0.0000). Aggravated skeletal changes were found in infants with lower birth weight(r= -0.3822, p=0.01). Interobserver variation in grading skeletal change was 42.9%, and intraobserver variation was 18.4%. Biochemical parameters such as serum calcium, phosphate, alkaline phosphatase, parathromone, calcitonin and 25-hydroxy-vitamine D did not vary significantly according to either birth weight or skeletal change(p > 0.05). Premature osteopenia is more effectively diagnosed by measuring whole body BMD using DXA than by grading radiographical skeletal change or by biochemical parameters

    Full Text Available Objective: To evaluate the effect of ethanolic extract of Pericampylus glaucus (Lam Merr (P. glaucus on biochemical parameters in high fats diets treated rats. Methods: The effect of P. glaucus extract on biochemical parameters was studied in male Sprague Dawley rats. The high-fat diets along with standard normal laboratory rat’s diets were given for a period of 28 days along with ethanolic extract of P. glaucus and standard drug. The standard group was treated with simvastatin at dose of 80 mg/kg and the tested groups were treated with ethanol extract of P. glaucus at 400, 600 and 800 mg/kg daily for 28 days of the experiment. The weight of animals in each group was measured weekly and the effect of extract and standard on serum lipids profile was evaluated at the end of the study. Results: The results showed that the ethanolic extract of P. glaucus at different doses of 400, 600 and 800 mg/kg and standard drug induced a significant reduction in the body weight (P < 0.001, total cholesterol, triglycerides (TG, low density lipoproteins (LDL and uric acid levels and increase (P < 0.001 in high density lipoproteins (HDL as compared to untreated hyperlipidemic group. Conclusions: The present work indicates that the ethanolic extract significantly suppressed the biochemical parameters in high fats diet treated animals, suggesting the antihyperlipidemic potential of P. glaucus.

    Cancer treatment with cyclophosphamide (CP) may result in reproductive toxicity as one of its side effects. The pumpkin seed is a rich natural source of antioxidant. We have assessed the possible protective efficacy of pumpkin seed extract on sperm characteristics, biochemical parameters and epididymal histology of CP-treated rats. Male adult Wistar rats were categorised into four groups. Group 1 served as control and received intraperitoneal (IP) injection of isotonic saline solution. Group 2 rats were treated with CP by IP injection in a single dose of 100 mg/kg body weight, only once. Group 3 and 4 received CP plus 300 and 600 mg/kg pumpkin seed extract respectively. Six weeks after treatment, sperm characteristics, biochemical parameters and histopathological changes were examined. Results showed that, sperm characteristics in CP-treated rats were significantly decreased. Biochemical analysis results showed that the co-administration of 300 mg pumpkin seed extract could increase the total antioxidant capacity (TAC) level significantly. In CP-treated rats, histopathological changes such as vacuolisation, disorganisation and separation of epididymal epithelium were observed as well. Interestingly, pumpkin seed extract could improve the above-mentioned parameters remarkably in CP-treated rats. Our findings indicated that pumpkin seed extract might be used as protective agent against CP-induced reproductive toxicity. © 2013 Blackwell Verlag GmbH.

    A study was conducted using 240 female day-old broiler chicks to evaluate the effects of dietary chromium picolinate (CrPic), peppermint essential oil (P.mint), or their combination on growth performance and blood biochemical parameters of female broiler chicks raised under heat stress conditions (HS, 23.9 to 38 °C cycling). Average daily gain (ADG), average daily feed intake (ADFI), and feed conversion ratio (FCR) were obtained from 1 to 42 days of age. Furthermore, at the end of the experiment (day 42), birds were bled to determine some blood biochemical parameters and weighed for final body weight (BW). ADFI, ADG, and BW were not influenced significantly by dietary CrPic and P.mint ( P > 0.05). A significant interaction between dietary CrPic and P.mint on FCR ( P = 0.012) was detected. FCR significantly decreased in chicks fed the diet including both CrPic and P.mint compared with the CrPic group. Significant interaction between dietary P.mint and CrPic on serum concentrations of triglycerides, glucose, and albumin were observed ( P dietary treatments ( P > 0.05). The serum concentrations of glucose, triglycerides were decreased ( P dietary supplementation with combined P.mint and CrPic could have beneficial effects on some blood biochemical parameters of female chicks reared under heat stress conditions.

    Full Text Available SHROB rats have been suggested as a model for metabolic syndrome (MetS as a situation prior to the onset of CVD or type-2 diabetes, but information on descriptive biochemical parameters for this model is limited. Here, we extensively evaluate parameters related to CVD and oxidative stress (OS in SHROB rats. SHROB rats were monitored for 15 weeks and compared to a control group of Wistar rats. Body weight was recorded weekly. At the end of the study, parameters related to CVD and OS were evaluated in plasma, urine and different organs. SHROB rats presented statistically significant differences from Wistar rats in CVD risk factors: total cholesterol, LDL-cholesterol, triglycerides, apoA1, apoB100, abdominal fat, insulin, blood pressure, C-reactive protein, ICAM-1 and PAI-1. In adipose tissue, liver and brain, the endogenous antioxidant systems were activated, yet there was no significant oxidative damage to lipids (MDA or proteins (carbonylation. We conclude that SHROB rats present significant alterations in parameters related to inflammation, endothelial dysfunction, thrombotic activity, insulin resistance and OS measured in plasma as well as enhanced redox defence systems in vital organs that will be useful as markers of MetS and CVD for nutrition interventions.

    Full Text Available Empirical relationships for magnitude scales and fault parameters were produced using 436 Iranian intraplate earthquakes of recently regional databases since the continental events represent a large portion of total seismicity of Iran. The relations between different source parameters of the earthquakes were derived using input information which has usefully been provided from the databases after 1900. Suggested equations for magnitude scales relate the body-wave, surface-wave as well as local magnitude scales to scalar moment of the earthquakes. Also, dependence of source parameters as surface and subsurface rupture length and maximum surface displacement on the moment magnitude for some well documented earthquakes was investigated. For meeting this aim, ordinary linear regression procedures were employed for all relations. Our evaluations reveal a fair agreement between obtained relations and equations described in other worldwide and regional works in literature. The M0-mb and M0-MS equations are correlated well to the worldwide relations. Also, both M0-MS and M0-ML relations have a good agreement with regional studies in Taiwan. The equations derived from this study mainly confirm the results of the global investigations about rupture length of historical and instrumental events. However, some relations like MW-MN and MN-ML which are remarkably unlike to available regional works (e.g., American and Canadian were also found.

    The testing of general relativity at cosmological scales has become a possible and timely endeavor that is not only motivated by the pressing question of cosmic acceleration but also by the proposals of some extensions to general relativity that would manifest themselves at large scales of distance. We analyze here correlations between modified gravity growth parameters and some core cosmological parameters using the latest cosmological data sets including the refined Cosmic Evolution Survey 3D weak lensing. We provide the parametrized modified growth equations and their evolution. We implement known functional and binning approaches, and propose a new hybrid approach to evolve the modified gravity parameters in redshift (time) and scale. The hybrid parametrization combines a binned redshift dependence and a smooth evolution in scale avoiding a jump in the matter power spectrum. The formalism developed to test the consistency of current and future data with general relativity is implemented in a package that we make publicly available and call ISiTGR (Integrated Software in Testing General Relativity), an integrated set of modified modules for the publicly available packages CosmoMC and CAMB, including a modified version of the integrated Sachs-Wolfe-galaxy cross correlation module of Ho et al. and a new weak-lensing likelihood module for the refined Hubble Space Telescope Cosmic Evolution Survey weak gravitational lensing tomography data. We obtain parameter constraints and correlation coefficients finding that modified gravity parameters are significantly correlated with σ 8 and mildly correlated with Ω m , for all evolution methods. The degeneracies between σ 8 and modified gravity parameters are found to be substantial for the functional form and also for some specific bins in the hybrid and binned methods indicating that these degeneracies will need to be taken into consideration when using future high precision data.

    Various parameters were measured during the period of composting of dairy manure and rice chaff in different ratios (dairy manure/rice chaff=V/V, pile 1: 75/25; pile 2: 80/20; pile 3: 85/15) to evaluate their suitability as indicators for the composting process. The temperature in pile 1 increased rapidly and remained above 60 °C for 30 days, while the temperature in pile 3 increased slowly relative to the other two piles. Furthermore, the degradation of organic substrates, as indicated by the reduction of C/N ratio, was rapid in pile 1 (below 20% 28 days after beginning of the composting). The major fluctuations of various water-soluble fractions in all piles were observed during the first 3 weeks, and the results in general showed that the highest microbial populations and enzymatic activities also appeared in this phase. Various parameters indicated that the rapid composting method was a feasible one for treating agricultural wastes. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Aim: This study was conducted to evaluate the physiological and biochemical effect in chickens of the Ross breed of a food enriched with agroindustrial waste. Materials and Methods: The food is one of the main components of the total cost for the production of chickens. Rations should be formulated to provide the correct balance of energy, protein, amino acids, minerals, vitamins and essential fatty acids, to allow optimal growth and performance. This study was intended to evaluate a natural feed for chicken, made from corn, yucca meal, eggshells, orange peel, soybean meal, salt and garlic, enriched with agroindustrial waste (molasses, milk whey and ferment of coffee. The weight gain was evaluated in broilers using a diet enriched with different agroindustrial wastes, with respect to a control food of the same composition but not containing residue. To develop the experiment 120 male Ross 308 chicks were used, these were evaluated for 6 weeks. Physicochemical test for the food and the agroindustrial waste were performed; moisture was determined; organic carbon, organic material and the ash, to characterize the agroindustrial wastes, the reducing sugars content using a spectrophotometer at 540 nm and proteins through the Kjeldahl method was evaluated. During the experiment, the weight gain of chickens and feed conversion was evaluated; the end of the experiment the weight of eviscerated channel relative weight breast, thighs, pancreas, and abdominal fat was determined, besides including blood chemistries as determination of cholesterol, triglycerides, and glucose. Finally, the microbiological analyzes to detect the presence of Escherichia coli in the cecum was determinate. Data were analyzed by InfoStat statistical program using the generalized linear model procedure. The statistical comparison was made by Tukey test at the 95% probability level. Results: After the evaluation, fed chickens with the treatments food + milk whey (FMW and food

  1. Relating stick-slip friction experiments to earthquake source parameters

    2012-01-01

    Analytical results for parameters, such as static stress drop, for stick-slip friction experiments, with arbitrary input parameters, can be determined by solving an energy-balance equation. These results can then be related to a given earthquake based on its seismic moment and the maximum slip within its rupture zone, assuming that the rupture process entails the same physics as stick-slip friction. This analysis yields overshoots and ratios of apparent stress to static stress drop of about 0.25. The inferred earthquake source parameters static stress drop, apparent stress, slip rate, and radiated energy are robust inasmuch as they are largely independent of the experimental parameters used in their estimation. Instead, these earthquake parameters depend on C, the ratio of maximum slip to the cube root of the seismic moment. C is controlled by the normal stress applied to the rupture plane and the difference between the static and dynamic coefficients of friction. Estimating yield stress and seismic efficiency using the same procedure is only possible when the actual static and dynamic coefficients of friction are known within the earthquake rupture zone.

    Full Text Available Perinatal immune challenge leads to neurodevelopmental dysfunction, permanent immune dysregulation and abnormal behaviour, which have been shown to have translational validity to findings in human neuropsychiatric disorders (e.g. schizophrenia, mood and anxiety disorders, autism, Parkinson's disease and Alzheimer's disease. The aim of this animal study was to elucidate the influence of early immune stimulation triggered by systemic postnatal lipopolysaccharide administration on biochemical, histopathological and morphological measures, which may be relevant to the neurobiology of human psychopathology. In the present study of adult male Wistar rats we examined the brain and plasma levels of monoamines (dopamine, serotonin, their metabolites, the levels of the main excitatory and inhibitory neurotransmitters glutamate and γ-aminobutyric acid and the levels of tryptophan and its metabolites from the kynurenine catabolic pathway. Further, we focused on histopathological and morphological markers related to pathogenesis of brain diseases--glial cell activation, neurodegeneration, hippocampal volume reduction and dopaminergic synthesis in the substantia nigra. Our results show that early immune stimulation in adult animals alters the levels of neurotransmitters and their metabolites, activates the kynurenine pathway of tryptophan metabolism and leads to astrogliosis, hippocampal volume reduction and a decrease of tyrosine hydroxylase immunoreactivity in the substantia nigra. These findings support the crucial pathophysiological role of early immune stimulation in the above mentioned neuropsychiatric disorders.

    Biochemical changes that are taking place in patients with periodontitis 1 and 2 the quality of the individuals place in a laqtatdegidrogenazis, alkaline phosphatase activity increase and reduced activity amilazais. Therefore we can conclude that, there is an increase in superoxide substances, which causes an increase in the oral cavity patobakteriebis and quality of periodontitis. The grape seed and coriander oil is of vegetable origin and antioxidant drugs. Their action causes a statistically significant increase in the amilazis, alkaline phosphatase and laqtatdegidrogenazis reduction, while the latter leads pH - rate of return to oral fluid. It should be noted that the positive effect of coriander oil, but less effective.

    Full Text Available An 8-wk experiment was conducted to evaluate the effect of replacing fish meal (FM with soy protein isolate (SPI on the growth, digestive enzyme activity and serum biochemical parameters of juvenile Amur sturgeon (Acipenser schrenckii. SPI was used to replace 0, 25, 50, 62.5, 75, 87.5, 100% of dietary FM and 100% replacement supplemented crystalline amino acid. Healthy sturgeon with an average initial weight of 26.38±0.24 g were randomly assigned to 24 aquaria (8 treatments with triplicates each at an initial stocking density of 11 fish per aquarium and cultured for 8 wks. The results showed that 75.00% or more substitution resulted in a poor weight gain rate, feed conversion ratio and survival rate compared to that of fish fed the control diet (p<0.05, whereas no significant differences were observed between diets of 25.00% to 62.50% substitution. Protease, lipase and amylase activity in foregut, mid-gut and hindgut were significantly (p<0.05 decreased by diets where SPI replacement levels were 62.50% or more. Levels of serum total protein (TP and globulin decreased significantly from 21.03, 10.34 to 14.05, 5.63 g/L with the increasing dietary SPI (p<0.05, but alkaline phosphatase activity significantly increased (p<0.05. In addition, supplemental crystalline amino acid in the FM absence diet did not improve growth performance, intestine digestive enzyme activities and serum biochemical parameters. In conclusion, the results from this study showed adverse effects of inclusion of SPI in diets on growth performance, feed utilization and serum biochemical parameters in juvenile Amur sturgeon. Based on WGR and replacement ratio presented in this report, a 57.64% replacement level was recommended.

    Fifty-one Simmental crossbred steers (357.0 ± 16.5 kg) were used to compare a standard total mix ration (TMR) with variants on animal performance, ruminal fermentation, blood biochemical parameters, and carcass characteristics. Corn grain and cotton seed meal were partially replaced by ensiled mulberry leaves (EML) or sun-dried mulberry fruit pomace (SMFP). Experimental diets had similar amounts of crude protein (CP), acid detergent fiber (ADF), and metabolizable energy (ME). Animals were divided into three groups: control group (CONT), 8% EML group, and 6.3% SMFP group. Performance, including average daily weight gain (ADG), and dry matter intake (DMI), was measured. Blood and rumen samples were collected at the end of the experiment (16 weeks). There were no differences in final body weight (P = 0.743), ADG (P = 0.425), DMI (P = 0.642), or ADG/DMI (P = 0.236) between the groups. There were no differences (P = 0.2024) in rumen pH values; ammonia N was lower (P = 0.0076) in SMFP than in the EML and CONT groups. There were differences in the concentrations of total and individual volatile fatty acids, while no differences were determined in blood biochemical parameters (i.e., plasma glucose, urea concentrations, triglycerides, total protein, insulin, IgG, alanine transaminase, and aspartate aminotransferase, P ≥ 0.098). No differences were observed in carcass characteristics (P ≥ 0.513), tenderness (P = 0.844), adipose and lean color values (P ≥ 0.149), and chemical composition (P ≥ 0.400); however, intramuscular fat was lower in the EML and SMFP groups compared to the CONT animals (P = 0.034). In conclusion, diets supplemented with these two mulberry products in an isocaloric and isonitrogenous manner have similar effects to corn grain and cotton seed meals on steer performance, blood biochemical parameters and carcass characteristics, with the exception of ruminal VFA concentrations and lower intramuscular fat content.

    Reproductive toxicity is one of the side effects of cyclophosphamide (CP) in cancer treatment. Pumpkin seeds and Zingiber officinale are natural sources of antioxidants. We investigated the possible protective effect of combined pumpkin seed and Zingiber officinale extracts on sperm characteristics, epididymal histology and biochemical parameters of CP-treated rats. Male adult Wistar rats were divided randomly into six groups. Group 1, as a control, received an isotonic saline solution injection intraperitoneally (IP). Group 2 were injected IP with a single dose of CP (100 mg/kg) once. Groups 3 and 4 received CP plus 300 and 600 mg/kg combined pumpkin seed and Zingiber officinale extract (50:50). Groups 5 and 6 received only 300 and 600 mg/kg combined pumpkin seed and Zingiber officinale extract. Six weeks after treatment, sperm characteristics, histopathological changes and biochemical parameters were assessed. In CP-treated rats, motile spermatozoa were decreased, and abnormal or dead spermatozoa increased significantly (P < 0.001) but administration of the mixed extract improved sperm parameters. Epididymal epithelium and fibromascular thickness were also improved in extract-treated rats compared to control or CP groups. Biochemical analysis showed that the administration of combined extracts could increase the total antioxidant capacity (TAC) level significantly in groups 3, 4, 5 and 6. Interestingly, the mixed extract could decrease most of the side effects of CP such as vacuolization and separation of epididymal tissue. Our findings indicated that the combined extracts might be used as a protective agent against CP-induced reproductive toxicity.

    Full Text Available This study evaluated the effects of probiotic, Lactobacillus plantarum on serum biochemical and some immune parameters of immunized rainbow trout weighting 29.6±1.84 g, with streptococcosis/lactococosis vaccine at 16±1.5°C, for 60 days. A commercial diet was used as the control. Fish in the first treatment were immunized with streptococcosis/lactococosis vaccine in bathing route for 1 min. In the second group, the vaccinated trout were also fed diet containing L. plantarum (108 CFU g-1. In the third treatment, fish were only fed the diet supplemented with L. plantarum (108 CFU g-1. The results showed that vaccinated trout with or without L. plantarum feeding diets significantly decreased heterophils. Meanwhile it enhances serum lysozyme, alternative complement activities, antibody titer, total leukocytes, lymphocytes, and serum biochemical parameters, including ALP, IgM, and total protein levels compared to control groups. Moreover, the highest levels of above mentioned parameters were found in vaccinated fish that fed L. plantarum. In addition, the vaccinated fish that fed L. plantarum showed significantly elevated cholesterol levels compared to the control group. The results showed that the dietary L. plantarum improved the immunity of immunized trout with streptococcosis/lactococosis vaccine.

    This study had the aim of evaluating the effects of medium-chain fatty acids (MCFA) on performance, carcass characteristics, some blood parameters and antibody titre against sheep red blood cells (SRBC) in quail. A total of 240 quail chicks were allotted to 4 treatments consisting of respectively 0, 1, 2 and 4 g/kg dietary MCFA. There were no significant differences in body weight, feed intake and feed conversion ratio among treatments at different stages of the experiment. MCFAs had no significant effect on breast, thigh, liver, spleen and bursa of Fabricius weight ratios. However, the relative weight of abdominal fat significantly decreased in quail receiving 0.2 and 0.4 MCFA as compared to other treatments. Concentrations of low-density lipoprotein-cholesterol (LDL), triglycerides and total cholesterol were decreased and high-density lipoprotein (HDL)-cholesterol was increased in quail chicks receiving MCFA compared with control quail chicks. The concentrations of SRBC antibody were not statistically different among treatments. It is concluded that MCFA significantly decreased LDL, triglycerides, cholesterol and abdominal fat and increased HDL in quail chicks.

    Full Text Available The purpose of this study was to assess the correlation between health-related quality of life (HRQoL and clinically relevant osteodensitometric and biochemical parameters in postmenopausal osteoporotic women. Bone mineral density (BMD and T scores of the lumbar vertebrae and femoral neck were assessed in 100 osteoporotic women (56 without previous fractures and 44 with previous fractures using dual x-ray absorptiometry. The Fracture Risk Assessment Tool (FRAX index for major osteoporotic and hip fractures was calculated based on demographic data and hip BMD. Venous blood samples were taken from each subject for biochemical analysis (serum calcium, phosphorus, alkaline phosphatase and vitamin D levels. HRQoL was assessed using the QUALEFFO-41 questionnaire (domains: Health perception, Pain, and Physical, Social and Mental function. Basic participant characteristics (age, menopause length, body mass index, smoking habits, hereditary tendency towards fracture, fracture history correlated with some of the QUALEFFO-41 domains, but the correlation coefficients were low (r<0.3, except in the case of the correlation between Pain and fracture history (r=0.638. Of the six variables included in the multiple regression model, fracture history was shown to be the most significant predictor with respect to the following three QUALEFFO-41 domains: Pain (b=20.511, Social function (b=2.548 and Health perception (b=3.185. Correlation analysis showed that after adjustment for basic characteristics, BMD and T score of the femoral neck and Pain (r=0.331 and r=0.449, respectively, Social function (r=0.422 and r=0.419 and Health perception (r=0.434 for T score of the femoral neck exhibited the strongest correlations. Vitamin D was negatively correlated with Mental function, while the other biochemical parameters exhibited variable correlations with the QUALEFFO- 41 domains (r≈0.2-0.5. Our study confirmed the previously established relationship between BMD of the

    The aim of the current study was to measure circulating metabolic and inflammation-related biochemical analytes in obese cats before and after weight loss. Thirty-seven overweight neutered cats were studied, median body weight 6.85 kg (range, 4.70 to 10.30 kg), representing a range of ages and both sexes. An individualized weight-loss program was devised for each cat and monitored until completion. Body fat mass was determined by dual-energy x-ray absorptiometry, whereas plasma concentrations of acute-phase proteins (APPs; eg, haptoglobin and serum amyloid A), hormones (eg, insulin, IGF-1, and adiponectin), and enzymes (eg, butyrylcholinesterase and paraoxonase type 1 [PON-1]) associated with inflammation and metabolic compounds (eg, glucose) were also measured. No significant changes were found in APPs after weight loss (P > 0.3), but significant increases in plasma adiponectin (P = 0.021) and IGF-1 (P = 0.036) were seen, whereas insulin (P cats that failed to complete weight loss than cats that were successful, whereas glucose concentration was greater. Finally, multivariable linear regression analysis showed that lean tissue loss during weight management was associated with percentage weight loss (greater weight loss, greater lean tissue loss; R = 0.71, P < 0.001) and plasma adiponectin concentration before weight loss (lesser adiponectin, more lean tissue loss; R = -0.52, P = 0.023). In conclusion, various metabolic abnormalities occur in feline obesity, and these can be linked to outcomes of weight-loss programs. The changes that occur with weight loss suggest an improved metabolic status. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available The purpose of this study was to investigate the changes in higher fatty acids and related biochemical characteristics of flue-cured tobacco during the process of aging. The concentration of total lipids in flue-cured tobacco decreased gradually during natural aging, but the concentration of individual principal higher fatty acids in flue-cured tobacco changed much differently during aging. Myristic acid (C14:0 increased constantly during the whole aging process. Stearic acid (C18:0 and oleic acid (C18:1 increased at the initial stages of aging and reached maximum contents after one year of aging, but decreased thereafter. Palmitic acid (C16:0, linoleic acid (C18:2, and linolenic acid (C18:3 decreased constantly throughout aging, especially the linolenic acid content which decreased drastically. Furthermore, the ratio of unsaturated fatty acids (C18:1; C18:2; C18:3 and saturated fatty acids (C14:0; C16:0; C18:0 decreased continuously during aging, from 1.00 at the initial stage to 0.43 at the end of aging, when it seemed to be stabilized. The maximum rate of decrease of the ratio was between 12 to 18 mo during aging. The activity of lipoxygenase (LOX and peroxidation value (POV initially increased and reached their highest levels after 6 mo of aging, but steadily decreased thereafter. The acid value (AV and malondialdehyde (MDA content increased during the first 12 mo of aging, then decreased rapidly after 12 and 18 mo, respectively.

  17. Effects of Discontinuous Administration of Dietary Mannan oligosaccharide and β-1,3-glucan on Hematological and Blood Serum Biochemical Parameters of Rainbow trout (Oncorhynchus mykiss

    Full Text Available Introduction Bans and restrictions of antibiotics as feed additives in fish culture in many countries have resulted in the increase in studies on alternative dietary supplements such as prebiotics to enhance the health and production of cultured fish. Prebiotics are nondigestible food ingredients that beneficially affect the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the colon. In addition, prebiotics promote the growth of lactic acid bacteria that are beneficial to health and lessen the density of pathogenic microorganisms. Because of the conservation of immune system, it is suggested that alternate administration of different immunostimulants may activate different parts of immune system of shrimps and take advantage of different immunostimulants to solve the problem of immunity fatigue and enhance the immunity continuously. However, there is no report on the discontinuous administration of immunostimulants for rainbow trout. Thus, considering the strategic importance of this species, the goal of this study was to assess the effects of discontinuous administration of dietary mannan oligosaccharide and β-1,3-glucan on hematological and blood serum biochemical parameters of rainbow trout. Materials and Methods A 6-week trial was conducted to compare the effects of discontinuous administration of dietary mannan oligosaccharide and β-1,3-glucan on hematological and blood serum biochemical parameters of rainbow trout (Oncorhynchus mykiss. Four feeding strategies were set, including feeding prebiotic-free diet continuously (control, feeding dietary prebiotic continuously (1.5 g kg-1, feeding dietary alternately (one week prebiotic+one week control diet and 2 Day prebiotic+5 Day control diet. Juveniles were fed the experimental diet in rate of 4% of the body weight per day, spread across two feeding time. At the end of the experiment, three fish were sampled randomly from each tank and were

    18F-fluoride PET/CT exhibits high sensitivity to delineate and measure the extent of bone metastatic disease in patients with prostate cancer. 18F-fluoride PET/CT could potentially replace traditional bone scintigraphy in clinical routine and trials. However, more studies are needed to assess repeatability and biological uptake variation. The aim of this study was to perform test-retest analysis of quantitative PET-derived parameters and blood/serum bone turnover markers at the same time point. Ten patients with prostate cancer and verified bone metastases were prospectively included. All underwent two serial 18F-fluoride PET/CT at 1 h post-injection. Up to five dominant index lesions and whole-body 18F-fluoride skeletal tumour burden were recorded per patient. Lesion-based PET parameters were SUVmax, SUVmean and functional tumour volume applying a VOI with 50% threshold (FTV 50% ). The total skeletal tumour burden, total lesion 18F-fluoride (TLF), was calculated using a threshold of SUV of ≥15. Blood/serum biochemical bone turnover markers obtained at the time of each PET were PSA, ALP, S-osteocalcin, S-beta-CTx, 1CTP and BAP. A total of 47 index lesions and a range of 2-122 bone metastases per patient were evaluated. Median time between 18F-fluoride PET/CT was 7 days (range 6-8 days). Repeatability coefficients were for SUVmax 26%, SUVmean 24%, FTV 50% for index lesions 23% and total skeletal tumour burden (TLF) 35%. Biochemical bone marker repeatability coefficients were for PSA 19%, ALP 23%, S-osteocalcin 18%, S-beta-CTx 22%, 1CTP 18% and BAP 23%. Quantitative 18F-fluoride uptake and simultaneous biochemical bone markers measurements are reproducible for prostate cancer metastases and show similar magnitude in test-retest variation.

    Pregnancy is accompanied by several hemodynamic, biochemical and hematological changes which revert to normal values after labor. The mean values of these parameters have been reported for developed countries, but not for Mexican women. Furthermore, labor constitutes a stress situation, in which these factors may be altered. It is known that serologic increase of heat shock protein (Hsp) 70 is associated with abnormal pregnancies, presenting very low level in normal pregnant women. Nevertheless, there are no studies where these measurements are compared in healthy pregnant women at their third trimester of pregnancy (3TP) and the active labor phase (ActLP). Seventy five healthy Mexican pregnant women were included. Hemodynamic, biochemical and hematological parameters were obtained in all cases, and serum Hsp70 levels were measured in a sample of 15 women at 3TP and at ActLP. Significant differences were found in most analysis performed and in Hsp70 concentration at 3TP as compared to ActLP, however all were within normal range in both conditions, supporting that only in pathological pregnancies Hsp70 is drastically increased. Results obtained indicate that 3TP and ActLP have clinical similarities in normal pregnancies, therefore if abnormalities are found during 3TP, precautions should be taken before ActLP.

    Full Text Available The purpose of this study was to evaluate the efficacy of yeast glucomannan (YG and sodium bentonite (SB in reducing the toxicity in broilers fed a diet naturally contaminated with aflatoxin. Three hundred 7-day-old Ross 308 strain broilers were chosen and randomly assigned to 10 dietary treatments. Serum biochemical parameters and pathological changes in the liver were investigated at 42 d of age. Chickens fed a diet containing 250 ppb of aflatoxin displayed a decrease in uric acid, cholesterol, and triglycerides, and an increase in serum activities of AST and ALT when compared to control group. There were considerable gross and histopathological hepatic lesions (P < 0.05 in the form of small to moderate hydropic and/or fatty degeneration, bile duct hyperplasia, periportal fibrosis, cells infiltration, and congestion, in chickens fed the 250 ppb aflatoxincontaining diet. The addition of YG and SB to the aflatoxin-containing diet partially reduced the negative effects of aflatoxin. The 0.1% YG supplementation to the aflatoxin-contaminated diet significantly prevented the pathological effect of aflatoxin on serum biochemical parameters and liver, and was found to be more effective than other treatments.

    2011-06-01

    Full Text Available BACKGROUND: Sickle cell anemia is a hemoglobinopathy caused by a mutation that results in the production of an abnormal hemoglobin molecule, hemoglobin S (Hb S. This is responsible for profound physiological changes, such as the sickling of red blood cells. Several studies have shown that hydroxyurea protects against vaso-occlusive crises. OBJECTIVE: The aim of this study was to evaluate the oxidative stress associated with biochemical parameters in patients with sickle cell anemia treated with hydroxyurea. METHODS: The study was conducted with 20 male and 25 female patients at the Hospital Universitário Walter Cantídio. The patients were divided into two groups: a study group (n = 12, patients with sickle cell anemia who were receiving hydroxyurea and a control group (n = 33 of sickle cell anemia patients not submitted to hydroxyurea treatment. The biochemical parameters analyzed were ferritin, transferrin, and serum iron. Glutathione was measured in its reduced form to analyze the oxidative state. RESULTS: The results showed insignificant increases in the levels of serum iron, transferrin and ferritin in patients treated with hydroxyurea when compared with those who did not take the medication. However, the glutathione levels were significantly higher in patients taking hydroxyurea than in controls. CONCLUSION: These results indicate that hydroxyurea possibly acts as an antioxidant by increasing glutathione levels.

    This study aimed to evaluate the effects of a supplement that contains resveratrol and hyaluronic acid (RH supplement) in aged lame horses. A total of 16 horses of both sexes, aged between 15 and 22 years, weighing between 350-450 kg and showing lameness due to arthritis of the knee, hock, stifle, and fetlock joints and stiffness owing to ageing were used for the study. They comprised eight horses that were administered the RH supplement for three weeks and eight others that served as controls and were given only a Saccharomyces cerevisiae yeast strain used as carrier in the supplement. Blood samples were collected from each horse before supplementation (week 0) and at weekly intervals for the three weeks of the experiment. Biochemical parameters including creatine kinase, aspartate aminotransferase, urea, glucose, total cholesterol, sodium, potassium, chloride, and calcium were measured by standard methods. There was a significant (P˂0.05) reduction in values of creatine kinase and glucose in the horses administered the RH supplement. It was concluded that the RH supplement may reduce the level of these biochemical parameters and their deleterious effects especially during ageing in horses.

    Tumor Necrosis Factor (TNF-alpha) is expressed primarily in adipocytes and elevated levels of this cytokine have been associated with obesity. The purpose of this investigation was to test whether the TNF-alpha -308 polymorphism were associated with insulin resistance or obesity related traits in non-diabetic and diabetic patients visiting Sheikh Zayed Hospital, Lahore, Fatima Hospital and Irfan Clinic in Sargodha. In non diabetic subjects the AA allele carriers, compared with homozygous G allele carriers had significantly lower (28%) triglyceride values and 15% higher HDL yal ues, whereas other parameters tested 81id not show any significant variation. In diabetic patients the AA allele carriers, compared with GG allele carriers, besides having 31 % higher FBS and 26% higher creatinine, had 20% higher cholesterol and 34% higher triglycerides. The HDL values were 14% less, compared to GG allele carriers. In normal subjects (BMI 22.85:1:0.25 kgim2), the AA allele carriers showed 132%, 125%, 65% and 112% higher triglycerides, cholesterol and LDL values compared with GG allele carriers. The HDL and creatinine did not show any significant change. In the overweight subjects (BMI: 27.17+-0.17 kgim/sup 2/) all these values were lower than in AA allele carriers compared with GG allele carriers. The AA allele carries had FBS, triglycerides, cholesterol and LDL 28%, 48%, 14% and 14% lower than in the GG allele' carriers, respectively. In obese subjects, (BMI: 36.73+-0.78kgm/sup 2/), however, the FBS, triglycerides, cholesterol and creatinine values were 5%, 8%, 7% and 14% higher in AA allele carries compared to GG allele carriers, respectively. The LDL content was 8% lower in AA allele carrier as compared with the respective GG allele carriers, It is concluded that replacement of G at -308 with A leads to reduced risk for cardiovascular disease in non-diabetic subject, whereas in diabetic patients this mutation-increases the risk of CVD. Using BMI as index of obesity, it was

    Diseases of the cardiovascular system is one of the most common causes of death among people over 65 years. Due to its course and incidence are a major cause of disability and impaired quality of life for seniors, as well as a serious economic problem in health care. Important role in the prevention of cardiovascular disease plays making systematic physical activity, which is a component of any rehabilitation program. Regular physical training by doing cardio-and vasoprotective has a beneficial effect on cardiovascular status and physical performance in patients with diagnosed coronary heart disease, regardless of age. The aim of this study was to evaluate the effect of controlled exercise on selected biochemical parameters and functional myocardial infarction. A group of 89 patients were divided into 3 subgroups. In group I (n = 30) was performed 2 weeks cardiac rehabilitation program, in group II (n = 30) 4 weekly. Streamline the program consisted of a series of interval training performed using a bicycle ergometer and general exercise. The remaining group (gr. III, n = 29) participated in individually selected training program. In all subjects before and after the training cycle underwent thoracic impedance plethysmography, also determined the level of plasma natriuretic peptide NT-proBNP and echocardiography and exercise test. After training, in groups, which carried out a controlled physical training, improvement was observed: exercise capacity of patients respectively in group I (p = 0.0003), group II (p = 0.0001) and group III (p = 0.032), stroke volume SV, cardiac output CO and global myocardial contractility, there was also reduction in the concentration of natriuretic peptide NT-proBNP. Furthermore, the correlation between the results shown pletyzmography parameters and NT-proBNP, SV, CO and EF. Regular physical training as part of the cardiac rehabilitation has a beneficial effect on biochemical parameters and functional myocardial infarction in patients

    This study aimed to evaluate the validity of the suggested method (SM) to estimate the urinary level of seven biochemical parameters within 24 hours with an innovative formula using morning and random urine specimens. A total of 133 clients referring to the laboratory of the Endocrinology & Metabolism Research Institute, Tehran University of Medical Sciences, participated voluntarily in the investigation with providing three urine samples of 24-hour, morning and random. Seven biochemical parameters (calcium, phosphorus, urea, creatinine, uric acid, microalbumin and protein) were measured in all three samples. After applying the proposed formula and the formula of the parameter-to-creatinine ratio (p/c), the results obtained from morning and random samples were compared statistically with those of 24-hour urine samples. Compared to the p/c ratio method, nearly all the results of the SM were more correlated with the 24-hour method (24-hrM). Among the results obtained in the SM, the values of urea, calcium and phosphorus in the morning urine and those of uric acid, microalbumin, protein and creatinine in the random urine showed higher correlation with the respective results of the 24-hrM. The new method seems to be a feasible alternative to the methods of 24-hour and p/c ratio for measuring morning values of urea, calcium and phosphorus as well as random values of uric acid, microalbumin, protein and creatinine. This method is a compromised method when 24 hours urine specimen is impossible to get by certain patients. © 2017 by the Association of Clinical Scientists, Inc.

    Protein-energy wasting (PEW) is prevalent in haemodialysis. Obesity is an independent risk factor of kidney insufficiency, but it is proposed to have beneficial roles in better outcomes in the final stage of disease. Better nutritional status and body reserves are among probable mechanisms, but direct examinations are limited. The present study aimed to investigate whether obese patients have preferable nutritional status compared to normal weight patients based on malnutrition inflammation score (MIS) and other PEW parameters in haemodialysis. This case-control study investigated 52 normal weight (18.5 < body mass index (BMI) < 25 kg/m 2 ) and 48 obese (BMI≥30 kg/m 2 ) patients on regular haemodialysis. PEW was assessed based on anthropometric and biochemical factors, recent weight changes, appetite, anorexia, dietary intake and MIS. Obese patients had better MIS compared with the normal weight group (P < 0.001), although varying degrees of wasting were prevalent among this group too (75% mild and 25% moderate wasting). The obese group had less significant weight loss (4.2 vs 8%) and anorexia and better appetite. However, a considerable percentage of patients in both groups showed muscle (94.6% of normal weight and 19.5% of obese) and peripheral fat tissue (89.2% of normal weight and 31.7% of obese) losses compared to the 50th percentile. Biochemical parameters were not significantly different between groups except for triglyceride (P = 0.001), transferrin and total iron-binding capacity (P = 0.028). MIS was significantly better in obese patients; however, both groups showed degrees of wasting based on MIS and other PEW parameters. Nutritional status of obese haemodialysis patients should be monitored regularly because of high risk of PEW like other BMI categories. © 2017 Dietitians Association of Australia.

    Full Text Available AIM Role of Interleukin-6 and HS-CRP Levels in the assessment of active thyroid eye disease. MATERIALS & METHODS A prospective observational study of 30 patients from the age group of 20-60 years with thyroid eye disease done at Regional Institute of Ophthalmology. All patients were subjected to detailed history, ocular examination, systemic examination, biochemical analysis and Imaging. Patients are categorised as mild, moderate and severe active disease based on clinical activity score. For the period of two years, patients are followed at regular periodic intervals according to the severity of disease and results were analysed. RESULTS Out of 30 patients studied, majority of the patients were females (60%, and 70% of the patients had bilateral disease. Among 30 patients, 83.33% in hyperthyroid state, 3.33% in Hypothyroid state, 13.33% in Euthyroid state (Table 3. Smoking being important risk factor in 30% among males. 50% of patients presented with mild disease, 30% with moderate disease, 0% with severe disease. IL-6, HS-CRP levels are increased only in patients with severe active disease (Table 6. Remission attained in all patients when treated earlier with steroids. CONCLUSION Identifying disease activity early and aggressive treatment with systemic steroids in active phase of moderate and severe disease has reduced the morbidity associated with disease. Correlation of IL-6, HS-CRP, TFT levels are significantly increased only in patients with active phase of severe thyroid eye disease but not significantly elevated in active phase of moderate disease. Another pitfall is IL-6 is an expensive ELISA based diagnosis. Thus, IL-6 & HS-CRP cannot be routinely used to screen patients with Thyroid eye disease.

    Understanding of soil phosphorus (P) adsorption chemistry is essential for evolving best fertilizer management practices aimed at enhancing fertilizer P use efficiency and environment quality. Soil chemical parameters which govern P adsorption maxima and binding strength in calcareous and non-calcareous soils were determined. Five soils representing three different parent materials i.e. mixed mineralogy alluvium, loess and non calcareous sandstone were sampled at genetic horizons in each profile. Phosphorus adsorption isotherm was developed for each of the 32 soil samples by equilibration of two g air dry soil with 0 to 4000 mgl/sup -1/ (0 to 125 mM) P in 20 ml of 10 mM KCI; and fitted to Langmuir and Freundlich equations. The chemical parameters i.e. pH, CaCO/sub 3/, total and dissolved organic carbon, exchangeable calcium, dithionite extractable iron (Fe/sub d/) and aluminum (AI/sub d/), oxalate extractable iron (Fe/sub o/) and aluminum (Al/sub o/) and as a test for plant available P extractable with NaHCO/sub 3/ were determined. The Fruendlich equation, an empirical relation between adsorbed and solution P, fitted the adsorption isotherms better than the Langmuir equation which relates adsorption to solid surface coverage by adsorbate. Adsorption maxima at low affinity sites positively correlated with soil CaCO/sub 3/ due to precipitation as Ca-P and to extractable iron oxide; and the binding strength of high affinity (kJ sites correlated positively with soil Fe/sub d/, Al/sub o/, AI/sub d/, and crystalline iron oxide (Fe/sub d/-Fe/sub o/) contents. The Freundlich parameter b/sub r/, adsorption exponent which signifies sorption intensity also positively correlated with soil Fe/sub d/, Fe/sub cr/ and Aid contents. Phosphorus adsorption at its low concentration in equilibrium solution seems to be governed by soil iron oxides and precipitation as Ca-P is important only at high P concentration, less frequently achieved in farm fields.

    The present study aimed to evaluate the effect of propolis use on hematological and serum biochemical parameters in Blue-fronted Amazons (Amazona aestiva). For this, 12 adult birds were distributed randomly into individual cages, divided into treatments with different propolis levels (A = 0.0%; B = 0.5%; and C = 1.0%), in 3 distinct phases (I, II, and III), with 15-d duration for phases I and III and 30 d for phase II, totaling 60 d. In phases I and III, all birds received treatment A ration, and in phase II received A, B, or C (4 birds per treatment). At the end of each phase, blood was collected for biochemical and hematological evaluations. The variables were analyzed by ANOVA (P < 0.05). Results suggest that 0.5% propolis reduced lactate dehydrogenase levels, whereas treatment B augmented hemoglobin concentrations and eosinophil count. It is concluded that 0.5% propolis improves levels of lactate dehydrogenase, hemoglobin, and eosinophils. © 2014 Poultry Science Association Inc.

    Full Text Available Rhamdia quelen (silver catfish and Leporinus obtusidens (piava were exposed to a commercial formulation Roundup(r, a glyphosate-based herbicide at concentrations of 0.2 or 0.4 mg/L for 96 h. The effects of the herbicide were analyzed on the alanine aminotransferase (ALT and aspartate aminotransferase (AST activities and glucose in plasma, glucose and protein in the mucus layer, nucleotide hydrolysis in the brain, and protein carbonyl in the liver. The parameters were chosen, owing to a lack of information concerning integrated analysis, considering oxidative damage parameters, liver damage, and effects on the mucus layer composition and triphosphate diphosphohydrolase (NTPDase activities. Plasmatic glucose levels were reduced in both species, whereas the transaminase activities (ALT and AST increased after exposure to the herbicide. Herbicide exposure increased protein and glucose levels in the mucus layer in both species. There was a reduction in both NTPDase and ecto-5'-nucleotidase activity in the brain of piava, and increased enzyme activity in silver catfish at both concentrations tested. The species showed an increase in protein carbonyl in the liver after exposure to both concentrations of the glyphosate. Our results demonstrated that exposure to Roundup(r caused liver damage, as evidenced by increased plasma transaminases and liver protein carbonyl in both of the fish species studied. The mucus composition changed and hypoglycemia was detected after Roundup(r exposure in both species. Brain nucleotide hydrolysis showed a different response for each fish species studied. These parameters indicated some important and potential indicators of glyphosate contamination in aquatic ecosystems.

    Children of mothers after liver transplantation (LT) are exposed during fetal life to the immunosuppressive agents. These drugs may have hepatotoxic and nephrotoxic effects. The aim of the work was to assess liver and kidney parameters of children born from mothers who had LT. The research included 51 children of mothers after LT and 51 children from a control group who were born in the First Department of Obstetrics and Gynecology in Warsaw between 2001 and 2013. The control group consisted of children born in the similar gestational age. Analysis concerned neonates, infants, and children older than 12 months. Two liver parameters (alanine transaminase [ALT] and aspartate transaminase [AST]) as well as two kidney parameters (urea and creatinine) were assessed. For statistical analysis we used Fisher's exact test and the Mann-Whitney test. All children from the LT group had correct ALT levels. In the control group, 5 of 51 cases (9.8 %) had levels that were greater than the norm, and those cases concerned only children younger than 12 months. The average concentration of ALT in the LT group was 15.14 U/L and the average for the control group was 22.6 U/L (P = .012699, Mann-Whitney test). Three of 51 children in the LT group (5.9%) and 8 of 51 (15.7%) in the control group had AST levels that were increased (P = .2003; Fisher's exact test). Incorrect AST levels were reported in all age groups. Incorrect values of kidney parameters concerned only neonates. Increased creatinine levels were reported in 3 of 51 cases (5.9%) in the LT group and in 1 of 51 cases (1.96%) in the control group (P = .6175; Fisher's exact test). The average concentration of creatinine in children of mothers after LT was 0.51 mg/dL, and the average of the control group was 0.44 mg/dL (P = .223698; Mann-Whitney test). Only 1 of 51 children in the LT group (1.96%) had an increased urea level. All children from both the LT and the control groups had normal ultrasound images of urinary tract and

    Currently light emitting diodes (LEDs) are considered to be most preferable source for space plant growth facilities. We performed a complex study of growth and photosynthesis in Chinese cabbage plants (Brassica chinensis L.) grown with continuous LED lighting based on red (650 nm) and blue (470 nm) LEDs with a red to blue photon ratio of 7:1. Plants grown with high-pressure sodium (HPS) lamps were used as a control. PPF levels used were about 100 μmol/(m2 s) (PPF 100) and nearly 400 μmol/(m2 s) (PPF 400). One group of plants was grown with PPF 100 and transferred to PPF 400 at the age of 12 days. Plants were studied at the age of 15 and 28 days (harvest age); some plants were left to naturally end their life cycle. We studied a number of parameters reflecting different stages of photosynthesis: photosynthetic pigment content; chlorophyll fluorescence parameters (photosystem II quantum yield, photochemical and non-photochemical chlorophyll fluorescence quenching); electron transport rate, proton gradient on thylakoid membranes (ΔpH), and photophosphorylation rate in isolated chloroplasts. We also tested parameters reflecting plant growth and productivity: shoot and root fresh and dry weight, sugar content and ascorbic acid content in shoots. Our results had shown that at PPF 100, plants grown with LEDs did not differ from control plants in shoot fresh weight, but showed substantial differences in photophosphorylation rate and sugar content. Differences observed in plants grown with PPF 100 become more pronounced in plants grown with PPF 400. Most parameters characterizing the plant photosynthetic performance, such as photosynthetic pigment content, electron transport rate, and ΔpH did not react strongly to light spectrum. Photophosphorylation rate differed strongly in plants grown with different spectrum and PPF level, but did not always reflect final plant yield. Results of the present work suggest that narrow-band LED lighting caused changes in Chinese

    Potassium sorbate is the potassium salt of sorbic acid, is a widespread and efficient antioxidant that has multiple functions in plants, traditionally associated with the reactions of photosynthesis; however, it has moderate toxicity to various species including rat, fish, bacteria and human health. The effects of potassium sorbate on the movement and photosynthetic parameters of Euglena gracilis were studied during short-term exposure. Potassium sorbate showed acute toxicity to the green flagellate E. gracilis affecting different physiological parameters used as endpoints in an automatic bioassay such as motility, precision of gravitational orientation (r-value), upward movement and alignment, with mean EC50 values of 2867.2 mg L(-1). The concentrations above 625 mg L(-1) of potassium sorbate induce an inhibition of the photosynthetic efficiency and electron transport rate and, in concentrations more than 2500.0 mg L(-1), the Euglena cells undergo a complete inhibition of photosynthesis even at low light irradiation.

    Oxidative stress due to hyperglycemia is a major cause of diabetes complications. The aim of this study was to evaluate the effects of pomegranate seed oil (PSO) on serum biochemical parameters, cardiomyopathy and nephropathy induced by diabetes mellitus. W/A adult rats were divided into four groups (12 each): group 1, received saline (1 mL/kg), group 2, received streptozotocin (STZ, 65 mg/kg, a single dose as i.p.), groups 3 and 4, received STZ + PSO (0.4 and 0.8 mL/kg, daily by gavage, respectively). After three weeks, six rats of each group and one week later the remaining animals were anesthetized, blood samples were taken for measuring serum biochemical parameters. Sections of heart and kidneys were used for histopathological studies and the remaining tissues were homogenized for measuring malondialdehyde (MDA) and total sulfhydryl groups. Significant elevation of serum creatinine and urea, LDL, triglyceride, glucose levels as well as urine markers, MDA levels in tissue homogenates and a significant decrease in total thiol content and serum HDL were observed in STZ-treated group as compared with control group. PSO treatment resulted in a significant decrease in tissue MDA content, serum creatinine and urea levels as well as urine markers as compared with STZ-treated group. Lipid profile was ameliorated with PSO treatment. PSO also significantly reversed STZ-induced depletion in thiol content and histological abnormality. Effect of PSO was more specific at 28th than 21th days of study. The results showed that PSO has a protective effect against diabetes complications in rats.

    Full Text Available The aim of the work was to study the influence of rhamnolipid biocomplex and ethylthiosulfanilate on field pea and sorghum plants when growing in petroleum contaminated soil. Plant seeds were treated with solutions of rhamnolipid biocomplex or ethylthiosulfanilate (0.01 g/l before planting and grown in containers with soil artificially contaminated with petroleum (5, 8 and 10%. Effect of rhamnolipid biocomplex and ethylthiosulfanilate was determined by the determination of growth (weight, length plants and biochemical parameters (content of photosynthetic pigments, hydrogen peroxide, malondialdehyde. The stimulating effect of rhamnolipid biocomplex and ethylthiosulfanilate on growth parameters of field pea was shown: the shoot mass has significantly increased on 39%, root mass – on 26% if compared with the control. For sorghum somewhat smaller increase of growth parameters was observed. Under the influence of rhamnolipid biocomplex and ethylthiosulfanilate the content of photosynthetic pigments in field pea and sorghum has also increased. It was determined that the action rhamnolipid biocomplex and ethylthiosulfanilate promoted the decrease of indicators of plant oxidative reactions if compared with control: the content of hydrogen peroxide – in average on 15% and 16%, malondialdehyde – on 13.5% and 16% respectively. The results of the study testify to the effectiveness of rhamnolipid biocomplex and ethylthiosulfanilate as growth stimulators for field pea and sorghum, as well as improvement of adaptive capability of plants to unfavorable conditions. It creates the prospects of their application as effective and ecologically safe substances for the intensification of contaminated soil phytoremediation.

    Mathematical modelling is fundamental to understand the dynamic behavior and regulation of the biochemical metabolisms and pathways that are found in biological systems. Pathways are used to describe complex processes that involve many parameters. It is important to have an accurate and complete set of parameters that describe the characteristics of a given model. However, measuring these parameters is typically difficult and even impossible in some cases. Furthermore, the experimental data are often incomplete and also suffer from experimental noise. These shortcomings make it challenging to identify the best-fit parameters that can represent the actual biological processes involved in biological systems. Computational approaches are required to estimate these parameters. The estimation is converted into multimodal optimization problems that require a global optimization algorithm that can avoid local solutions. These local solutions can lead to a bad fit when calibrating with a model. Although the model itself can potentially match a set of experimental data, a high-performance estimation algorithm is required to improve the quality of the solutions. This paper describes an improved hybrid of particle swarm optimization and the gravitational search algorithm (IPSOGSA) to improve the efficiency of a global optimum (the best set of kinetic parameter values) search. The findings suggest that the proposed algorithm is capable of narrowing down the search space by exploiting the feasible solution areas. Hence, the proposed algorithm is able to achieve a near-optimal set of parameters at a fast convergence speed. The proposed algorithm was tested and evaluated based on two aspartate pathways that were obtained from the BioModels Database. The results show that the proposed algorithm outperformed other standard optimization algorithms in terms of accuracy and near-optimal kinetic parameter estimation. Nevertheless, the proposed algorithm is only expected to work well in

    Full Text Available Aim: This study was conducted on Ouled Djellal ewes in arid area of south-east Algeria in order to reveal the influence of altitude and landforms on some hematological and biochemical parameters. Materials and Methods: A total of 160 ewes having 3-5 years of age, multiparous, non-pregnant, non-lactating and reared in arid areas of South East Algeria were included. Blood samples were divided according to factors of altitude and landform (plain region at 150 m above sea level, tableland region at 600 m above sea level and mountain region at 1000 m above sea level. The whole blood was analyzed for hematology, and plasma samples for biochemical analysis. Results: The study found lowest glucose concentrations were detected in tableland region at 600 m. In plain region at 150 m, ewes had a higher (p<0.01 concentration of cholesterol and triglyceride. Furthermore, a higher concentration of total proteins (p<0.01 and urea (p<0.05 were detected in plain region at 150 m. The average blood creatinine concentration in mountain ewes at 1000 m and tableland ewes at 600 m were higher (p<0.05 that in plain ewes at 150 m. The highest calcium concentration was found at the altitude of 150 m and the lowest at the altitude of 1000 m (1.12±0.35 mmol/L vs. 0.52±0.03 mmol/L. Phosphorus levels were higher at altitudes of 150 m than at the altitude of 600 m and 1000 m (0.93±0.42 mmol/L vs. 0.68±0.54 mmol/L, 0.23±0.01 mmol/L. The highest hemoglobin concentration and value of hematocrit were detected in mountain ewes at the altitude of 1000 m (120.61 g/L, 40% and the lowest at the altitude of 150 m (73.2 g/L, 31% (p<0.001. Conclusion: We concluded that hematological and biochemical parameters in Ouled Djellel ewes reared in arid area may be affected by altitude and landforms.

    The aim of the present study was to investigate anti-inflammatory activity of Diclocor in the setting of collagen-induced osteoarthritis in rats in comparison with its active monocomponents-diclofenac sodium and quercetin. The study was conducted on the model of collagen-induced osteoarthritis and included measurement of sialic acids, glycoproteins, C-reactive protein, prostaglandin E2, 6-keto-prostaglandin F1α, thromboxane B2, and leukotriene B4. Lastly, morphologic study with morphometry was also performed. Diclocor is superior to quercetin and diclofenac sodium by the degree of pharmacological effect on some of the studied parameters. The differences between the values were statistically significant. Diclocor is a promising corrector of inflammatory and destructive joint diseases. Owing to the presence of both diclofenac sodium and quercetin in its composition, Diclocor exhibits a complex mechanism of anti-inflammatory action affecting cyclooxygenase and lipoxygenase ways of arachidonic acid biotransformation.

    Effect of Capparis spinosa (C. spinosa) and Acacia arabica (A. arabica) dry powder as plant molluscicide on some glycolytic and gluconeogenic enzymes on snail tissues, was investigated. Lactate debydrogenase (LDH), Pyruvate Kinase (PK), Hexokinase (HK), phosphofructokinase (PFK), glucose phosphate isomerase (GPI) as important glycolytic enzymes, were markedly manipulated by both plants when measured one day and one week post-treatment. On the other hand glucose-6-phosphatase (G-6Pase), fructose 1.6 diphosphatase (FDpase), phosphoenol pyruvate carboxykinase (PEPCK) as gluconeogenic enzymes were significantly affected by the moluscicidal plants. In addition, some other parameters as glycogen, glucose, total protein, 5-nucleotidase alpha-hydroxybutyrate dehydrogenase (HBDH) and succinate dehydrogenase (SDH) as kreb's cycle enzyme were tested. As conclusion, LC25 and LC50 concentrations of C. spinosa and A. arabica might render B. alexandrina physiologically unsuitable for S. mansoni infection.

    Different monofloral honeys have a distinctive flavor and color because of differences in physicochemical parameters because of their principal nectar sources or floral types. Honey samples were collected from Apis mellifera colonies forged on 10 floras to analyze the quality of honey in terms of standards laid by Honey Grading and Marking Rules (HGMR), India, 2008 and Codex Alimentarious Commission (CAC), 1969 . The honey samples were analyzed for various physicochemical parameters of honey quality control, i.e., pH, total acidity, moisture, reducing sugars, non-reducing sugars, total sugars, water insoluble solids (WIS), ash content, 5-hydroxymethylfurfural content, and diastase value. The antioxidant potential was estimated using Folin-Ciocalteu reagent. Further, honey samples were assayed for antibacterial activities against clinical isolates of Staphylococcus aureus and Escherichia coli using the hole-plate diffusion method. The physicochemical variation in the composition of honey because of floral source shows Ziziphus honey with high pH and diastase values along with low acidity, whereas Helianthus honey contained high reducing sugar and low moisture content. Amomum, Brassica, Acacia, and Citrus contained lowest amount of non-reducing sugars, ash, WIS, and moisture, respectively. Lowest 5-hydroxymethylfurfural (HMF) value was detected in Amomum honey, while highest HMF value was observed with Eucalyptus. The maximum antibacterial and antioxidant potential was observed in Azadirachta and Citrus, respectively. The quality of honey produced by local beekeepers met HGMR and CAC standards, and the chemical composition and biological properties of honey were dependent on the floral source from which it was produced.

    Full Text Available BACKGROUND: Relationship of left ventricular diastolic dysfunction (LVDD with parameters that could provide more information than hemodynamic renal indexes has not been clarified. We aimed to explore the association of comprehensive renal parameters with LVDD in a community-based elderly population. METHODS: 1,166 community residents (aged ≥ 65 years, 694 females participating in the Shanghai Heart Health Study with complete data of renal parameters were investigated. Echocardiography was used to evaluate diastolic function with conventional and tissue Doppler imaging techniques. Serum urea, creatinine, urea-to-creatinine ratio, estimated glomerular filtration rate (eGFR and urinary albumin-to-creatinine ratio (UACR were analyzed on their associations with LVDD. RESULTS: The prevalence of LVDD increased in proportion to increasing serum urea, urea-to-creatinine ratio and UACR. These three renal parameters were found negatively correlated to peak early (E to late (A diastolic velocities ratio (E/A, and positively to left atrial volume index; UACR also positively correlated with E to peak early (E' diastolic mitral annular velocity ratio (E/E'. Serum urea, urea-to-creatinine ratio and UACR correlated with LVDD in logistic univariate regression analysis, and urea-to-creatinine ratio remained independently correlated to LVDD [Odds ratio (OR 2.82, 95% confidence interval (CI 1.34-5.95] after adjustment. Serum urea (OR 1.18, 95%CI 1.03-1.34, creatinine (OR 6.53, 95%CI 1.70- -25.02, eGFR (OR 0.22, 95%CI 0.07-0.65 and UACR (OR 2.15, 95%CI 1.42-3.24 were revealed independent correlates of advanced (moderate and severe LVDD. CONCLUSIONS: Biochemical parameters of renal function were closely linked with LVDD. This finding described new cardio-renal relationship in the elderly population.

    Measurement of the rates of important biogeochemical fluxes on regional or global scales is vital to understanding the geochemical and climatic consequences of natural biospheric processes and of human intervention in those processes. Remote data gathering and interpretation techniques were used to examine important cycling processes taking place in wetlands over large geographic expanses. Large area estimation of vegetative biomass and productivity depends upon accurate, consistent measurements of canopy spectral reflectance and upon wide applicability of algorithms relating reflectance to biometric parameters. Results of the use of airborne multispectral scanner data to map above-ground biomass in a Delaware salt marsh are shown. The mapping uses an effective algorithm linking biomass to measured spectral reflectance and a means to correct the scanner data for large variations in the angle of observation of the canopy. The consistency of radiometric biomass algorithms for marsh grass when they are applied over large latitudinal and tidal range gradients were also examined. Results of a 1 year study of methane emissions from tidal wetlands along a salinity gradient show marked effects of temperature, season, and pore-water chemistry in mediating flux to the atmosphere.

    Full Text Available The work presents the results of investigations of the effect of natural zeolite (clinoptilolite type on the degree of resumption of cloistral immunoglobulin, the value of hematological parameters and enzyme activity in blood serum (AST, ALT, and LDH, body mass, and daily growth of calves in the first three months of life. Investigations were carried out on three groups of 10 male and female calves each, with a 1:1 ratio of sexes, (control, K, and two experimental groups, I and II, of the black-and-white breed, Holstein type. All three groups of calves were fed with the usual rations (colostrum, collective cows' milk, fodder mix with 18% total proteins, and Lucerne hay.The experimental groups of calves, as opposed to the controls, received colostrums and collective cows' milk with the addition of a preparation based on natural zeolite in quantities of 5 and 10 g/l milk. The concentration of immunoglobulin G in blood serum of experimental groups of calves was significantly higher than the values of the control group (35.9±6.43 g/l in Group I; 32.5±7.39 g/l in Group II; 20.8±6.88 g/l in control group K. The results of the investigations of the values of hematological parameters (number of erythrocytes, hemoglobin concentration, and hematocrit value do not show any digressions from the physiological values and are approximately the same in the experimental and the control groups of calves, which indicates that the examined quality of the zeolite-based preparation did not affect the degree of the resumption of iron and other oligoelements significant for erythropoietin. The data on the enzyme activity in blood serum indicate that the examined preparation does not cause any significant functional or morphological changes in the tissue of parenchymatous organs or muscles. There were no significant disorders in the health of calves of the experimental groups, while 3 calves of the control group had gastrointestinal disorders (diarrhea. Calves of

    The aim of the present research was to discover plant food extracts and probiotics that may have bioactivity towards chronic inflammation. Three plant food extract mixtures expected to be rich in phenolic compounds, carotenoids and tocopherols were prepared. The anti-inflammatory activity of the different mixtures as well as probiotic bacteria (Bifidobacterium bifidum) were evaluated in adjuvant arthritis in rats. The anti-inflammatory effect, mechanism of action and safety of the three mixtures and Bifidobacterium bifidum were studied by measuring the size of inflammation and the determination of inflammatory and oxidative stress biomarkers, colonic bacteria profile and specific cytogenetic parameters. The contents of tocopherols, {beta}-carotene and phenolic compounds in the mixtures were determined. The results show that the tested mixtures and Bifidobacterium bifidum possess promising anti-inflammatory effects. The mechanism of action seems to involve a reduction in oxidative stress and inflammatory bio markers and an effect on colonic microflora. Genotoxicity and DNA fragmentation induced by adjuvant arthritis were prevented after supplementation with the tested mixtures. (Author) 61 refs.

    Aflatoxins as potent mycotoxins can influence vital parameters in chickens. Turmeric was used in decreasing toxic effect of mycotoxins on vital organs, traditionally. The study compared the protective effect of turmeric and Mycoad(TR) in broilers exposed to aflatoxin. Chickens (270) were divided into six groups. The chickens were fed a basal diet, turmeric extract (5 mg/kg diet), Mycoad(TR) (25 mg/kg diet), productive aflatoxin (3 mg/kg diet), aflatoxin plus turmeric extract (3 versus 5 mg/kg diet), and aflatoxin plus Mycoad(TR) (3 versus 25 mg/kg diet) in basal diet. At 28 d old, we determined plasma concentration of total protein, albumin, triglyceride, cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), calcium, potassium, phosphorous, uric acid, aspartate transferase (AST), and alanine aminotransferase (ALT). Furthermore, liver and kidney were sampled for pathological examination. Chickens fed turmeric with aflatoxin had significant lower ALT, AST, and uric acid than chickens fed aflatoxin (11.4 ± 0.79, 228 ± 9, and 6 ± 0.4 versus 17.2 ± 1.7, 283 ± 5, and 7.7 ± 0.1) whereas, total protein, calcium, and HDL values in chickens fed aflatoxin plus turmeric increased significantly (2.66 ± 0.16, 8.4 ± 0.2, and 920 ± 4.1 versus 1.7 ± 0.17, 7 ± 0.2, and 690 ± 4.8). Pathological examination revealed severe congestion, degeneration, and necrosis in liver and kidney in chickens that received aflatoxin. The study showed that turmeric may provide protection against the toxic effects of aflatoxin on liver and kidney.

    The aim of this study was to investigate effects of two dietary medicinal herbs, Rose hip (Rosa canina) and Safflower (Carthamus tinctorius) supplementation on growth performance, haematological, biochemical parameters and innate immune response of in juvenile beluga, Huso huso. Fish (26.3 ± 0.4 g) were allocated into 15 tanks (20 fish per tank) and triplicate groups were fed a control diet or diets containing 1% and 2% of medicinal herbs, respectively. Feed conversion ratio (FCR), specific growth rate (SGR) and condition factor (CF) did not show significant differences (P > 0.05) in fish given herbal diets. Significant differences were observed in number of white blood cells (WBC) and haemoglobin (Hb) values among the dietary treatments. The serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were significantly lower in supplemented diet groups compared with the control. Innate immune responses (lysozyme activity and ACH 50 ) were significantly higher in 2% Safflower-fed fish compared with other groups (P < 0.05). These results indicate that medicinal herbs in diets can be considered as a beneficial dietary supplement for improving the physiological parameters and enhance the immune response of Persian sturgeon.

    This study investigated the effect of dietary supplementation of probiotic Pedicoccus acidilactici and nucleotide (separately or combined) on growth performance, intestinal microbiota, hemato-immunological parameters, and immunity response in goldfish (Carassius auratus). Fish (average weight 5-6 g) were acclimatized and divided into eight experimental diets supplemented with P. acidilactici of different concentrations (0.1, 0.2, and 0.3% diet) and nucleotides (0 and 0.5% diet) for 6 months. Fish fed with experimental diets showed significant differences in terms of final weight, weight gain, feed conversion ratio, daily growth rate, and condition factor when compared to control diet (P < 0.05). Fish fed with probiotic (0.3%) separately and combined with nucleotide (0.5%) had highest RBC and WBC when compared to other diets (P < 0.05), while the highest values for Hb and Hct as well as total protein, glucose, albumin, and globulin were observed in probiotic (0.2%) and nucleotide (0.5%) combined diet. Serum lysozyme and anti-protease activities were significantly higher in probiotic (0.1 and 0.2%) and nucleotide (0.5%) combined diets. Similarly, these two diets combined showed the highest colonization of P. acidilactici when compared to other diets. In conclusion, combined dietary probiotic and nucleotide improve the growth performance, hemato-biochemical parameters, and intestine growth in C. auratus.

    Extracellular vesicles (EVs) from mesenchymal stromal cells (MSC) are emerging as valuable therapeutic agents for tissue regeneration and immunomodulation, but their clinical applications have so far been limited by the technical restraints of current isolation and characterisation procedures. This study shows for the first time the successful application of Raman spectroscopy as label-free, sensitive and reproducible means of carrying out the routine bulk characterisation of MSC-derived vesicles before their use in vitro or in vivo, thus promoting the translation of EV research to clinical practice. The Raman spectra of the EVs of bone marrow and adipose tissue-derived MSCs were compared with human dermal fibroblast EVs in order to demonstrate the ability of the method to distinguish the vesicles of the three cytotypes automatically with an accuracy of 93.7%. Our data attribute a Raman fingerprint to EVs from undifferentiated and differentiated cells of diverse tissue origin, and provide insights into the biochemical characteristics of EVs from different sources and into the differential contribution of sphingomyelin, gangliosides and phosphatidilcholine to the Raman spectra themselves.

    Full Text Available Heavy metals as pollutants in the working and living environment are a serious health and environmental problem because they are toxic, non-biodegradable, accumulate in living systems and have a long half-life in soil. Sources of lead contamination are combustion products in the chemical industry and metallurgy, industrial waste water, landfills, traffic etc. Lead enters into the body via the food chain and drinking water. In the body lead is deposited in the liver, kidneys, brain and mineral tissues. Excretion of lead causes damage to the epithelial cells of certain organs. High level exposure to cadmium is usually the result of environmental pollution by human activities. Exposure to cadmium can lead to acute and chronic tissue damage of various organs, including liver and kidneys in humans and in animals. In this paper we analyzed the effects of lead and cadmium exposure, in working and living environment, on the model system of experimental animals, particularly the activity of certain liver enzymes, acid and alkaline DNase, and standard biochemical blood parameters. The study showed that lead and cadmium significantly affect the protein content, red blood cells, hemoglobin and hematocrit, and the activity of liver enzymes. This harmful effect of this toxic metal can be reduced by the supplements.

    The incorporation of functional ingredients like amaranth (Amaranthus dubius Mart. ex Thell.) in bread making is a strategy to increase fiber intake, which is associated with beneficial health effects, improving glycemic response and lipid profile. Thirty male Sprague dawley rats were randomized into three groups: diet of bread with 0% amaranth (PA0, control), diet of bread with 10% amaranth (PA10) and bread diet with 20% amaranth (PA20) for determining the feed intake, weight gain, triglyceride, total cholesterol, VLDL-C, LDL-C, HDL-C, protein and postprandial glycemic response. Data were analyzed using a completely randomized with 10 replications analysis, using the comparison test of Tukey for biochemical parameters. Postprandial glycemic response was analyzed by the method of repeated measures over time. The daily intake and weight gain was not affected (P>0.05) in the groups with PA10 and PA20. The concentration of glucose, triglycerides and protein showed statistically significant differences (P>0.05) by the difference in content of amaranth diets. The values of total cholesterol, LDL-C, and atherogenic risk factor index were statistically significant (P. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

    The article studied UV-B effects on biochemical parameters and active ingredients in flowers of Qi chrysanthemum and Huai chrysanthemum during the bud stage. The experiment included four UV-B radiation levels (CK, ambient UV-B; T1, T2 and T3 indicated a 5%, 10% and 15% increase in ambient UV-BBE, respectively) to determine the optimal UV-B radiation intensity in regulating active ingredients level in flowers of two chrysanthemum varieties. Flower dry weight of two cultivars was not affected by UV-B radiation under experimental conditions reported here. UV-B treatments significantly increased the rate of superoxide radical production, hydrogen peroxide (H2O2) (except for T1) and malondialdehyde concentration in flowers of Huai chrysanthemum and H2O2 concentration in flowers of Qi chrysanthemum. T2 and T3 treatments induced a significant increase in phenylalanine ammonia lyase enzyme (PAL) activity, anthocyanins, proline, ascorbic acid, chlorogenic acid and flavone content in flowers of two chrysanthemum varieties, and there were no significant differences in PAL activity, ascorbic acid, flavone and chlorogenic acid content between the two treatments. These results indicated that appropriate UV-B radiation intensity did not result in the decrease in flower yield, and could regulate PAL activity and increase active ingredients content in flowers of two chrysanthemum varieties. © 2014 The American Society of Photobiology.

    This study aimed to investigate the 677C > T and 1298A > C MTHFR gene polymorphisms and their metabolic effects on the levels of folate, vitamin B12 and homocysteine in the serum of Turkish spina bifida occulta (SBO) patients and healthy individuals in disease. A case-control study was performed to detect 677C > T and 1298A > C MTHFR gene polymorphisms in 39 SBO patients and 34 healthy individuals. The folate, vitamin B12 and homocysteine concentrations in the serum of SBO and healthy individuals were evaluated and compared with MTHFR gene polymorphisms. 677 CC/CT/TT MTHFR genotype frequency differences between the SBO patients and controls were not significant (x(2)=3.325, P=0.068; x(2)=1.479, P=0.224; x(2)=0.275, P=0.600; respectively). 1298A > C MTHFR genotype frequency differences between the SBO patients and controls were significant (x(2)=8.477, P=0.004). The frequencies of the Aand C alleles of the 1298A > C polymorphism did not differ in a statistically significant manner between the groups (x(2)=0.576, P=0.448). The biochemical parameters were not significantly different between SBO patients and healthy individuals (P > 0.05). The 677C > T and 1298A > C polymorphisms of the MTHFR gene cannot be regarded as major risk factors for SBO in the Turkish patients 677TT homozygosity may affect the metabolism of homocysteine.

    Gestational diabetes mellitus (GDM) is defined as varying glucose intolerance, with first onset or recognition in pregnancy. This study evaluates clinical and biochemical parameters in a possible association between GDM and gingivitis. A total of 167 pregnant females was included in the study. There were 101 females with GDM and 66 females without GDM. Subgroups were created according to the presence or absence of gingival inflammation. Plaque index, bleeding on probing, and probing depth were recorded at four sites per tooth. Serum, saliva, and gingival crevicular fluid (GCF) levels of interleukin (IL)-6, IL-8, soluble receptor activator of nuclear factor-kappa B ligand (sRANKL), osteoprotegerin (OPG), B-cell activating factor (BAFF), and a proliferation-inducing ligand (APRIL) were determined by enzyme-linked immunosorbent assay. Data were analyzed by Kruskal-Wallis and Mann-Whitney U tests and Spearman correlation analysis. Age and anthropometric indices were higher in the GDM than non-GDM group (P gingivitis group than non-GDM with gingivitis group (P = 0.044). Serum and GCF BAFF (P gingivitis group than GDM without gingivitis group. The inflammatory response seems to be more pronounced in females with GDM. The observed increase in both local and systemic levels of inflammatory cytokines may suggest an interaction between gingivitis and GDM.

    Full Text Available The periparturient period is critical according to health, productivity and profitability. As this period is fundamental for the success of the lactation period, the interest in improving periparturient health by dietary supplements increased in recent years. The present study investigated the effects of feeding nicotinic acid (NA combined with varying dietary energy densities on immunological, hematological and biochemical parameters of periparturient cows differing in parity. Thirty-six multiparous and 20 primiparous dairy cows were enrolled in the study 42 days before expected parturition date until 100 days postpartum with the half of the cows being supplemented with 24 g of NA/d. After parturition a diet with 30% concentrate was fed to all cows which was followed by different concentrate escalation strategies. Dietary NA supplementation was ceased on day 24 postpartum. Dietary NA increased (P = 0.010 serum nicotinamide concentrations (mean of 3.35 ± 1.65 µg/mL, whereas NA could not be detected. Present data emphasize that periparturient cows are faced with major physiological challenges and that both parity-groups have different prerequisites to adapt to those changes irrespective of NA supplementation. The overfeeding of energy to cows which were similar in body condition score had only minor effects on periparturient immune system function and the metabolism of those cows.

    The 5'-nucleotidases constitute a ubiquitous family of enzymes that catalyze either the hydrolysis or the transfer of esterified phosphate at the 5' position of nucleoside monophosphates. These enzymes are responsible for the regulation of nucleotide and nucleoside levels in the cell and can interfere with the phosphorylation-dependent activation of nucleoside analogs used in therapies targeting solid tumors and viral infections. In the present study, we report the initial biochemical and functional characterization of a 5'-nucleotidase from Xylella fastidiosa that is related to the human cytosolic 5'-nucleotidase I. X. fastidiosa is a plant pathogenic bacterium that is responsible for numerous economically important crop diseases. Biochemical assays confirmed the phosphatase activity of the recombinant purified enzyme and revealed metal ion dependence for full enzyme activity. In addition, we investigated the involvement of Xf5'-Nt in the formation of X. fastidiosa biofilms, which are structures that occlude the xylem vessels of susceptible plants and are strictly associated with bacterial pathogenesis. Using polyclonal antibodies against Xf5'-Nt, we observed an overexpression of Xf5'-Nt during the initial phases of X. fastidiosa biofilm formation that was not observed during X. fastidiosa planktonic growth. Our results demonstrate that the de/phosphorylation network catalyzed by 5'-nucleotidases may play an important role in bacterial biofilm formation, thereby contributing novel insights into bacterial nucleotide metabolism and pathogenicity.

    Although connections between cognitive deficits and age-associated brain differences have been elucidated, relationships with motor performance are less well understood. Here, we broadly review age-related brain differences and motor deficits in older adults in addition to cognition-action theories. Age-related atrophy of the motor cortical regions and corpus callosum may precipitate or coincide with motor declines such as balance and gait deficits, coordination deficits, and movement slowing. Correspondingly, degeneration of neurotransmitter systems-primarily the dopaminergic system-may contribute to age-related gross and fine motor declines, as well as to higher cognitive deficits. In general, older adults exhibit involvement of more widespread brain regions for motor control than young adults, particularly the prefrontal cortex and basal ganglia networks. Unfortunately these same regions are the most vulnerable to age-related effects, resulting in an imbalance of "supply and demand". Existing exercise, pharmaceutical, and motor training interventions may ameliorate motor deficits in older adults. Copyright 2009 Elsevier Ltd. All rights reserved.

    An integrated, miniaturized, low-power instrument capable of the detection and early characterization of microbial life in the soil of Mars is proposed. Based on the detection apd monitoring of on-going metabolism as being the surest evidence for extant life, the experiments will probe for chirality in metabolism, for circadian rhythm, and for photosynthesis. However, the instrument package will also be able to detect biosignatures and a variety of other physical and chemical parameters of the Martian surface that have significance for life. These include the presence and the physical state of water, the existence of an oxidant, the pH and the penetrability of the soil. Using the legacy of the 1976 Viking Labeled Release (LR) life detection experiment in conjunction with state-of-the-art laser diode spectral analysis, the instrument can be flown stand-alone, with or without a rover, or as part of an MSL-type mission. Sterility for experiment integrity and for planetary protection is provided.

During the 8-to-21-day period, even if interaction between NPP levels and phytase sources was significant (P<0.01, BW, ADG and ADFI always increased due to dietary supplementation of phytase, with source not differing. Dietary high NPP enhanced serum calcium and P concentrations on day 21 and 42 (linear contrast, P<0.01, while decreased alkaline phosphatase (AKP activity on day 42 (linear contrast, P<0.001, and interaction was not significant. Both dietary sources of phytase decreased serum AKP activities on day 42 (P<0.001, and urea nitrogen content on day 21 (P<0.01 and 42 (P<0.001. Both phytase improved ash percentage on day 21 and P content in tibia at 21 and 42 days of age (P<0.001. The results confirmed that dietary supplementation of phytase may enhance P availability during the 8-to-21-day period. Nevertheless, no difference between the two phytase sources was observed.

    This study investigated effects of dietary supplementation with vitamin C, vitamin E on performance, biochemical parameters, and oxidative stress induced by copper toxicity in broilers. A total of 240, 1-day-old, broilers were assigned to eight groups with three replicates of 10 chicks each. The groups were fed on the following diets: control (basal diet), vitamin C (250 mg/kg diet), vitamin E (250 mg/kg diet), vitamin C + vitamin E (250 mg/kg + 250 mg/kg diet), and copper (300 mg/kg diet) alone or in combination with the corresponding vitamins. At the 6th week, the body weights of broilers were decreased in copper, copper + vitamin E, and copper + vitamin C + vitamin E groups compared to control. The feed conversion ratio was poor in copper group. Plasma aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase activities, iron, copper concentrations, and erythrocyte malondialdehyde were increased; plasma vitamin A and C concentrations and erythrocyte superoxide dismutase were decreased in copper group compared to control. Glutathione peroxidase, vitamin C, and iron levels were increased; aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and copper levels were decreased in copper + vitamin C group, while superoxide dismutase, glutathione peroxidase, and vitamin E concentrations were increased; aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase were decreased in copper with vitamin E group compared to copper group. The vitamin C concentrations were increased; copper, uric acid, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and malondialdehyde were decreased in copper + vitamin C + vitamin E group compared to copper group. To conclude, copper caused oxidative stress in broilers. The combination of vitamin C and vitamin E addition might alleviate the harmful effects of copper as demonstrated by decreased lipid peroxidation and hepatic enzymes.

    The purpose of this study is to determine the effect of L-ascorbic acid and alpha-tocopherol as well as combination of these vitamins with or without exposure to physical exercise on intensity of lipid peroxidation, activity of xanthine oxidase, activity of total antioxidative system, concentration of glutathione, and activity of catalase in the serum of guinea pigs. The experimental measurements of intensity of lipid peroxidation, activity of xanthine oxidase, activity of total antioxidative system, concentration of glutathione, and activity of catalase were done in the serum of guinea pigs. The animals were exposed to the test load to achieve exhaustion and the test was terminated when the animal for the third time to sink into the water. The results of this study demonstrated that endurance exercise of guinea pigs induced oxidative stress response in terms of increased lipid peroxidation and activity of xanthine oxidase in the serum of experimental animals. Our study investigated the antioxidant activity of L-ascorbic acid and alpha-tocopherol also measuring three protective markers in the serum: total antioxidant activity, content of glutathione and activity of catalase. The results obtained show that the vitamins influence the concentrations of above mentioned biochemical parameters, which points out their protective effect of swimming-induced oxidative stress. Single or combined administration of L-ascorbic acid and alpha-tocopherol caused significant inhibition of these markers indicating the important antioxidant activity of the vitamins. Results lead to conclude that the combined treatments with vitamins with or without exposure to physical exercise showed the clear synergistic effect..

    Full Text Available The objectives of this study were to study the effects of different levels of dietary copper on copper and zinc balance, plasma minerals and serum biochemical parameters of mink in the growing-furring periods. One hundred and five standard dark male mink were randomly assigned to seven groups with the following dietary treatments: basal diet with no supplemental Cu (Control; basal diet supplemented with either 6, 12, 24, 48, 96, or 192 mg/kg Cu from copper sulfate, respectively. The average daily gain (ADG linearly (P = 0.0026, P = 0.0006 responded to increasing levels of Cu; maximal growth was seen in the Cu24 group. Feed efficiency tended to improve with the increase of dietary copper level (linear P = 0.0010, quad, P = 0.0011. Fecal copper, urinary copper, retention copper responded in a linear (P < 0.05 fashion with increasing level of Cu. The effect of level of Cu was linear (P < 0.001 for plasma Cu concentration. The serum glutamic-oxalacetic transaminase (GOT and glutamic-pyruvic transaminase (GPT activities were increased linearly (P < 0.05 with dose of Cu, but serum total protein (TP and albumin (ALB concentrations decreased linearly (P < 0.05 as dietary copper levels increased. Effect of level of Cu was linear (P < 0.001 for serum ceruloplasmin (CER concentration or Cu-Zn superoxide dismutase (Cu-Zn SOD activity. Supplemental dose of Cu linearly decreased serum triglyceride (TG (P = 0.011 and total cholesterol (TC (P = 0.007. Our results indicated that the activity of Cu-dependent enzymes was enhanced by increasing dietary Cu concentration and that supplementation of Cu in the diet of mink could alter the plasma lipid profile and copper concentration.

    Full Text Available The aim of this study was to investigate the effects of administering antioxidants, including vitamin C and chitosan on oxidative stress markers in muscle as edible tissues of Cyprinus carpio exposed to cadmium chloride. In this experiment, by exposing to 0.2 mg/L cadmium chloride for 21 days, fish were fed a normal diet, diet containing chitosan (1000 mg/kg diet, vitamin C (1000 mg/kg diet or both vitamin C and chitosan. Oxidative stress markers, including the activity of catalase, total antioxidant and malondialdehyde (MDA as well as biochemical parameters, including the activity of aspartate aminotransferase (AST, alanine aminotransferase (ALT, creatine phosphokinase (CPK, lactate dehydrogenase (LDH, and acetylcholinesterase (AChE were measured. Fish exposure to cadmium chloride significantly increased AST, LDH, CPK, catalase, and MDA activity, while it significantly decreased AST and AChE activity, and levels of total antioxidant in muscle cells. Administration of chitosan or vitamin C alone or in combination with each other to fish exposed to cadmium chloride was effective in regulating ALT, CPK, and catalase activity. Although administration of vitamin C and chitosan caused a significant decrease in MDA, AST and LDH, these enzymes were still significantly higher than those in the control group. Administration of vitamin C and chitosan had no significant effects on the activity of AChE and levels of total antioxidant. Although, chitosan alone could not prevent oxidative stress damages in muscle tissues of cadmium-treated fish, administration of vitamin C combined with chitosan may increase the efficiency of antioxidant defense system and improve the detoxification system in the muscles of fish exposed to cadmium chloride.

    Full Text Available The present stduy was planned to investigate the relations of bone mineral density and biochemical markers of bone turnover with plasma levels of homocysteine, vitamin B12 and folate in postmenaposal women. The study was performed in 148 osteoporotic and 75 osteopenic postmenopausal patients. Control group included 61 age-matched healthy postmenopausal women with normal bone mineral density. Plasma homocysteine, serum vitamin B12, folate levels, biochemical markers of bone formation and resorption and lomber vertebra (L2-L4 bone mineral density were determined in study groups. In osteoporotic group, plasma homocysteine levels and both serum and urine markers of bone resorption were found to be increased and, vitamin B12 levels which were found to be significantly decreased had a significant correlation with osteocalcin levels. Althought less marked, similar findings were obtained in osteopenic group, as well. In summary, it was concluded that the reduction in vitamin-B12 levels in osteoporotic postmenaposal women may cause negative effects on bone tissue both by increasing bone resorption indirectly through an increment in homocysteine levels and by a reduction in the direct stimulatory effect of vitamin-B12 on osteoblast and may contribute to development of osteoporosis by shifting the balance between bone formation and resorption in favor of the latter. Therefore, it was suggested that determination of plasma homocysteine and vitamin B12 levels and vitamin B12 supplementation in deficient cases might be useful in treatment of osteoporosis.

    2014-08-01

    The kinetics of cultivation of zygomycete filamentous fungus Rhizopus oryzae in deproteinized whey medium in relation to chitosan production was studied here to optimize chitosan production from R. oryzae as well as utilize whey, a by-product of sweetmeat industry as a cheap source of sugar in the cultivation process. Chitosan content of R. oryzae biomass was found to be increased with time during cultivation and reached maximum (13·6%) after 72 h and then declined steadily. Maximum 1·13 g of chitosan was obtained from one litre of deproteinized whey medium. Concentration of lactose in the medium was observed to be reduced from 45·0 to 11·7 g l(-1) during cultivation resulting in decrease in biochemical oxygen demand (BOD) of whey by approx. 60%, and this was important from environmental point of view before discharging whey into any water body. However, no significant change in pH or titratable acidity was noted during the entire course of cultivation, probably due to good buffering capacity of the medium. Molecular weight of chitosan varied from 130 to 230 kDa depending on the time of cultivation, but no significant change in degree of deacetylation of chitosan (approx. 87%) was found during cultivation. Whey is the largest by-product of dairy industries, and its disposal is a big environmental issue because of its high biological oxygen demand (BOD) value. This study will help to lower BOD value of whey by using it as a cultivation medium for fungus R. oryzae that contains chitosan, a very commercially important material on its cell wall. Moreover, the study on biochemical changes in whey during cultivation process with R. oryzae will help to understand the exact changes occurring in the medium and optimize cultivation process to isolate chitosan in larger extent with better and uniform physicochemical properties. © 2014 The Society for Applied Microbiology.

    Full Text Available The objective of this study was to investigate the effects of L-carnitine on growth performance, organ weight, biochemical parameters of blood, heart and liver, and ascites susceptibility of broilers at different ages reared under a low-temperature environment. A total of 420 1-d-old male Ross 308 broilers were randomly assigned to two dietary treatments with fifteen replicates of fourteen broilers each. Treatment diets consisted of L-carnitine supplementation at levels of 0 and 100 mg/kg. At 11-d of age, low temperature stress was used to increase ascites susceptibility. Blood, heart and liver samples were collected at different ages for analysis of boichemical parameters. The results showed that, there was no significant difference in growth performance with L-carnitine supplementation, but the mortality due to ascites was significantly decreased. Dietary L-carnitine supplementation significantly reduced heart index (HI and ascites heart index (AHI on d 21, lung index (LUI on d 35 and liver index (LI on d 42. The broilers fed diets containing L-carnitine had significantly lower red blood cell counts (RBC, hemoglobin (HGB concentration and hematocrit (HCT on d 42. Dietary L-carnitine supplementation significantly reduced malondialdehyde (MDA content of heart tissue on d 21 and 35, and significantly increased total superoxide dismutase (T-SOD and Glutathione peroxidase (GSH-Px activity of the heart on d 21 and 42. L-carnitine supplementation significantly reduced serum triglyceride (TG content on d 28 and 35 and serum glucose (GLU on d 35 and 42, and significantly increased serum total protein (TP and globulin (GLO content on d 42. L-carnitine supplementation significantly enhanced liver succinodehydrogenase (SDH, malic dehydrogenase (MDH and Na+-K+-ATPase activity on d 28, and tended to reduce the lactic acid (LD level of liver on d 35 (p = 0.06. L-carnitine supplementation significantly reduced serum uric acid (UA content on d 28, 35 and 42

    Obesity and diabetes are major public health problems throughout the World. Obese individuals body mass index (BMI) is >30 kg/m2. Obesity is characterized by increased waist circumference, total body fat and hyperglycemia. The increased triglyceride and cholesterol level is also shown in obese individuals. The development of obesity is largely due to the consumption of high energy food and sedentary lifestyle. This study was held with the participation of patients applied to Siirt State Hospital endocrine policlinic for treatment. Our aim is to try to determine the biochemical relation and border line of obese and obese+diabetes mellitus patients. Patients and control group lipid profiles were studied in the hospital biochemisty laboratory. Laboratory results of diabetes+obese, obese and control groups were evaluated. Patients and control samples blood serum levels were compared according to their lipid profiles. In 2015, 735 diabetes mellitus type 2 patients applied to Endocrine polyclinic. Some of these patient's serum levels were evaluated. Difference between diabetes+obese and diabetes groups were near critical level for LDL and trigliserid. There were not observed statistically significant difference between groups in terms of HDL and cholesterol. There were found significant difference between groups for blood glucose pdiabetes patients blood serum values nearly close to each other. Obese subjects were been diabetic obese with age. In women obesity and diabetes mellitus prevalence were seen too much.

    The Irish population is at risk of vitamin D deficiency during the winter months, but the secular trend over the past 40 years is for marked improvement. Multiple sclerosis (MS) is common in Ireland with a latitudinal pattern favouring highest incidence in northern regions; MS is linked strongly with vitamin D status as a causal factor. We sought firstly to study the relationship between vitamin D status and vitamin D-related bone biochemistry, and secondly to evaluate if MS had an independent effect on vitamin D related markers of bone remodelling. Using a case-control design of 165 pairs (MS patient and matched control) residing in three different geographic regions during winter months, we measured serum 25-hydroxyvitamin D (25OHD), parathyroid hormone (PTH), C-terminal telopeptide of type I collagen (CTX) and total procollagen type I amino-terminal propeptide (PINP). Given the paired case-control design, associations were explored using mixed-effects linear regression analysis with the patient-control pair as a random effect and after log transformation of 25OHD. A two-way interaction effect was tested for vitamin D status (25OHD ppppp=0.921), CTX (p=0.912), or PINP (p=0.495). As regards an interaction effect, the presence of MS and 25OHD p=0.207). In conclusion, in Ireland in winter only a minority had any abnormality in the secondary indices of vitamin D deficiency, and MS had no independent effect on parathyroid status or bone remodelling activity.

    With the first three terms of Harris formula included and Mottelson's method followed, a new relation of the parameters of Bohr-Mottelson rotational spectra formula is brought forward. Superdeformed bands of even-even nuclei and normal deformed bands of nuclei in actinide and rare-earth are fitted with four-parameter Bohr-Mottelson rotational spectra formula. The relations of the parameters A, B, C, D are studied. The result show, for normal deformed bands, the new relation approach the experiment value in the same degree as the relation deduced from ab formula, but for superdeformed bands, the new relation is closer to the experiment than the relation deduced from ab formula. Three-parameter Harris formula may have better convergence than two-parameter Harris formula

    Full Text Available In aphids there is a fecundity-dispersal trade-off between wingless and winged morphs. Recent research on the molecular mechanism of wing morphs associated with dispersal reveals that insulin receptors in the insulin signaling (IS pathway regulate alteration of wing morphs in planthoppers. However, little is known about whether genes in the IS pathway are involved in developmental regulation in aphid nymphs with different wing morphs. In this study, we show that expression of the insulin-related peptide 5 gene (Apirp5 affects biochemical composition and embryo development of wingless pea aphids, Acyrthosiphon pisum. After comparing expression levels of major genes in the IS pathway between third instar winged and wingless nymphs, we found that Apirp5 showed higher expression in head and thorax of the wingless nymphs than in the winged nymphs. Although microinjection treatment affects physical performance in aphids, nymphs with RNA interference of Apirp5 had less weight, smaller embryo size and higher carbohydrate and protein contents compared to control group. Comparison between winged and wingless nymphs showed a similar trend. These results indicate that Apirp5 is involved in embryo development and metabolic regulation in wing dimorphic pea aphid.

    Cigarette smoking causes cardiovascular (CV) disease, but the relative roles of nicotine and other components of tobacco smoke remain unclear. We investigated the effect of stopping smoking by using nicotine replacement therapy (NRT) on hemorheology parameters, on the cotinine and thiocyanate plasma concentrations and the exhaled carbon monoxide (CO). Open, parallel-group trial (intervention group and control smokers). 197 males, aged 25-45 years, smoking > 20 cigarettes per day (cpd). 164 subjects were instructed to stop smoking and received NRT for 12 weeks and 33 acted as controls. After 12 weeks, NRT was discontinued and all subjects were followed-up at 26 weeks. Beginning with week 4, the treated subjects were divided into abstainers (self-reported, verified by exhaled CO hematocrit, white blood cells, cotinine and thiocyanate plasma concentrations and exhaled CO, all assessed at 4, 8, 12 and 26 weeks. After 6 months, plasma fibrinogen (228.2 vs. 275.4 mg/dl at baseline, p hematocrit and white blood cell count decreased to a greater extent in abstainers than in reducers and relapsers. Not only abstainers but also reducers did benefit of the temporarily stop smoking. Smoking cessation improved CV parameters despite the measured cotinine and thiocyanate plasma levels, and use of nicotine medications did not negate these improvements. A smoking cessation for a short time and smoking of reduced cpd also improved these parameters temporarily.

    Full Text Available The present study was performed with tilapia (Oreochromis niloticus to evaluate the effects of diet supplementation with grape seed proanthocyanidins (GSPs on fish growth performance, some serum parameters and body composition. Three hundred tilapia fingerlings with the initial average body weight of 9.50±1.25 g were randomly divided into five treatment groups with four replicates in each group and 15 fish in each replicate. The dietary GSPs levels of five treatment groups were 0 (control group, 200, 400, 600, and 800 mg/kg, respectively. The trial period was 49 days. Growth performance parameters were significantly improved by GSPs supplementation (P<0.05, while survival rates were similar among all groups (P>0.05. Serum parameter results showed that activities of aminotransferase aspartate in 200 and 400 mg/kg GSPs groups and alanine aminotransferase in 400 mg/kg GSPs group were lowered significantly (P<0.05. Levels of triglyceride and total cholesterol (except 200 mg/kg GSPs group were significantly lowered, while lysozyme activity and albumin level were significantly higher in fish of GSPs supplemented groups, independently from the level of supplementation. The highest crude protein level and lowest crude lipid level were found in fish of all GSPs supplemented groups, while levels of moisture and ash in fish of all groups were similar (P>0.05. The results indicated that dietary 200 mg/kg GSPs could exert beneficial effects on growth and body composition of tilapia fingerlings, and ameliorate serum biochemistry parameters related to health status.

    The purpose of this study was to explore in rats the possible influence of the type of dietary fat at two extreme levels of vitamin E on several biochemically determined hepatic changes and on a number of quantitatively analyzed structural and ultrastructural variations with age in hepatic cells. Six groups of weanling Wistar male rats were fed ad libitum isoenergetic diets containing similar amounts (15 g per 100 g diet) of saturated fat (coconut oil), unsaturated fat (safflower oil) or a combination of both at two levels of dl-alpha-tocopherol (2 or 200 mg per 100 g of diet). Determinations were performed in rats killed at 3, 6, 12, 18 and 24 months. Although in relation to age and irrespective of the type of diet, several of the biochemical parameters fluctuated with time, comparisons of the results between the youngest and oldest rats showed no changes in the levels of hepatic RNA, phospholipids, cholesterol, total tocopherols and total collagens, significant increases in DNA and triglycerides and a significant decrease in total protein. While the type of diet did not have in general significant influences on the levels of DNA, RNA, total protein and collagens, either the type of dietary fat and/or the levels of vitamin E had some definite effects on the levels of triglycerides, cholesterol, phospholipids and total tocopherols, as well as on the in vitro formation of malonaldehyde and on the eventual occurrence of in vivo lipoperoxidation (diene conjugation). These effects, however, varied in relation to the duration of the diverse dietary treatments. The morphologic studies indicated that all the livers had variable but generally moderate degrees of fatty changes (mainly due to triglyceride accumulation) which were attributed to the moderate obesity found in the rats. The mean nuclear and cell dimensions of hepatocytes, the number of binucleated hepatocytes, surface density of rough endoplasmic reticulum, numerical density of mitochondria and the fractional

    The aim of this study has been the biochemical demonstration of the presence of gamma-aminobutyric acid (GABA) in the Mediterranean sea fan Eunicella cavolini by means of high-performance liquid chromatography, and the description of the distribution pattern of GABA and its related molecules, glutamic acid decarboxylase (GAD), vesicular GABA transporter (VGAT) and one of the GABA receptors (GABA(B) R) by immunohistochemical methods. The interrelationships of GABA, GAD and GABA receptor immunoreactivity have been established by using double-immunohistochemical methods and confocal microscopy. The immunodetection of monoclonal and/or polyclonal antibodies has revealed GABA immunoreactivity throughout the polyp tissue, both in neuronal and non-neuronal elements. GAD immunoreactivity has been mostly localized in the neuronal compartment, contacting epithelial and muscular elements. GABA(B) R immunoreactivity appears particularly intense in the nematocytes and in the oocyte envelope; its presence in GAD-immunoreactive neurons in the tentacles suggests an autocrine type of regulation. Western blot analysis has confirmed that a GABA(B) R, with a molecular weight of 142 kDa, similar to that of rat brain, is present in E. cavolini polyp tissue. The identification of the sites of the synthesis, vesicular transport, storage and reception of GABA strongly suggests the presence of an almost complete set of GABA-related molecules for the functioning of the GABAergic system in this simple nervous system. The distribution of these different immunoreactivities has allowed us to hypothesize GABA involvement in nematocyst discharge, in body wall and enteric muscular contraction, in neuronal integration and in male gametocyte differentiation.

    The increasing trend of ban on the use of antibiotic growth promoters (AGPs) across the globe in the poultry industry has led to a growing need for alternatives to AGPs. Prebiotic, probiotic and their combination as a synbiotic have been considered as potential alternatives. This study aimed to investigate the effects of a prebiotic (isomaltooligosaccharide, IMO), a probiotic (PrimaLac®), and their combination (synbiotic) on hen performance, biochemical and haematological responses, and relative organ weights from 20 to 52 weeks of age. Supplementation of 1% IMO (PRE), 0.1% PrimaLac® (PRO) and 1% IMO + 0.1% PrimaLac® (SYN) improved (P feed intake and egg production at 20-36 weeks of age; body weight gain, feed conversion ratio and egg mass at 20-36 and 20-52 weeks of age; and egg weight at 20-36, 37-52 and 20-52 weeks of age. Compared to control-fed hens at 20-36 weeks of age, PRO- and SYN-fed hens produced less (P hens produced more large size eggs. From 37 to 52 weeks of age, PRE-, PRO- or SYN-fed hens produced less (P hens from 20 to 52 weeks of age. These results demonstrated the use of PRE, PRO and SYN as alternative feed additives to AGPs for improving the health and productivity of hens, while PRO is the best for commercial layer production to yield maximum profit.

    The aim of this study was to determine whether polycystic ovary syndrome (PCOS) affects the biochemical components of first trimester combined aneuploidy screening test. A case-control study was performed at a tertiary referral hospital between years 2007-2013. Singleton pregnancies in the first trimester (11(+0) -13(+6) week) who had a history of PCOS and underwent first trimester combined aneuploidy screening test were included in the study. Three hundred and seventeen women met the criteria for inclusion. Control group was formed by 942 healthy pregnant women with similar gestational and maternal ages using a 1 : 3 ratio. Pregnancy-associated plasma protein-A (PAPP-A), free β-human chorionic gonadotropin (fβ-hCG) and fetal nuchal translucency were compared between the study group and the controls. The biochemical components PAPP-A and fβ-hCG were significantly lower in the PCOS group compared with the control group (p = 0.001). There was no difference among groups with regard to the nuchal translucency measurements (p = 0.128). Our study shows that the levels of biochemical components of first trimester combined aneuploidy screening test (PAPP-A and fβ-hCG) are altered in pregnant women with PCOS. Future trials of larger scale are needed to asses any need for readjustment of the risk in the patient population with PCOS. © 2014 John Wiley & Sons, Ltd.

    Extensive herbicide usage has led to the evolution of resistant weed populations that cause substantial crop yield losses and increase production costs. The multiple herbicide resistant (MHR) Avena fatua L. populations utilized in this study are resistant to members of all selective herbicide families, across five modes of action, available for A. fatua control in U.S. small grain production, and thus pose significant agronomic and economic threats. Resistance to ALS and ACCase inhibitors is not conferred by target site mutations, indicating that non-target site resistance mechanisms are involved. To investigate the potential involvement of glutathione-related enzymes in the MHR phenotype, we used a combination of proteomic, biochemical, and immunological approaches to compare their constitutive activities in herbicide susceptible (HS1 and HS2) and MHR (MHR3 and MHR4) A. fatua plants. Proteomic analysis identified three tau and one phi glutathione S-transferases (GSTs) present at higher levels in MHR compared to HS plants, while immunoassays revealed elevated levels of lambda, phi, and tau GSTs. GST specific activity towards 1-chloro-2,4-dinitrobenzene was 1.2-fold higher in MHR4 than in HS1 plants and 1.3- and 1.2-fold higher in MHR3 than in HS1 and HS2 plants, respectively. However, GST specific activities towards fenoxaprop-P-ethyl and imazamethabenz-methyl were not different between untreated MHR and HS plants. Dehydroascorbate reductase specific activity was 1.4-fold higher in MHR than HS plants. Pretreatment with the GST inhibitor NBD-Cl did not affect MHR sensitivity to fenoxaprop-P-ethyl application, while the herbicide safener and GST inducer mefenpyr reduced the efficacy of low doses of fenoxaprop-P-ethyl on MHR4 but not MHR3 plants. Mefenpyr treatment also partially reduced the efficacy of thiencarbazone-methyl or mesosulfuron-methyl on MHR3 or MHR4 plants, respectively. Overall, the GSTs described here are not directly involved in enhanced rates of

    Multiorgan failure including liver dysfunction is a common finding in sickle cell anemia (SCA) patients, the cause of which is multifactorial with advancing age said to be a major determinant. There is a paucity of data on liver function among SCA patients in relation to age in northern Nigerian hospitals, including Ahmadu Bello University Teaching Hospital (ABUTH), Zaria. This study was to assess the biochemical liver function tests (LFTs) as they relate to age among SCA patients in steady state, with a view to improving the overall monitoring of these patients. This study was carried out in ABUTH, Zaria, Northern Nigeria. LFTs were carried out in 100 SCA and 100 apparently healthy participants (controls). The SCA group was made up of fifty adults and fifty children diagnosed of SCA, whereas the control group was made up of fifty adults and fifty children who were apparently healthy and had hemoglobin AA. Paired two-tailed Student's t-test for matched samples and Pearson's linear correlation statistical methods were employed for the data analysis using Microsoft Office Excel 2007. A P ≤ 0.05 was considered as statistically significant. The serum concentrations of total bilirubin (TB), alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and AST/ALT ratio were significantly higher in SCA patients compared to the controls (P = 0.001, P = 0.001, P = 0.05, P = 0.05 and P = 0.001, respectively). Serum total protein (TP) and ALB were significantly lower (P = 0.01 and P < 0.05, respectively) in SCA patients compared with the controls. The levels of TB, ALT, AST, ALP, and AST/ALT were significantly lower in SCA adults compared to SCA children, whereas TP and ALB were higher in SCA adults compared to the SCA children. There were significant negative correlations between age and each of TB, ALT, AST, ALP, and AST/ALT, and significant positive correlations between age and each of TP and ALB in SCA patients. There are mild LFTs derangements

    Peanut, an important oilseed crop, frequently encounters drought stress (DS) during its life cycle. In this study, four previously developed mtlD transgenic (T) peanut lines were used for detailed characterization under DS, at the reproductive stage using lysimeter system under controlled greenhouse conditions. In dry-down experiments, T lines maintained better photosynthetic machinery, such as, photosynthesis rate, stomatal conductance, transpiration rate, and SPAD (Soil-Plant Analyses Development) values, and had lower oxidative damage, including lipid membrane peroxidation and hydrogen peroxide and superoxide radical accumulation than WT, when exposed to 24 days of DS. WT plants had a more negative water potential (WP; up to -3.22 MPa) than T lines did (-2.56 to -2.71 MPa) at day 24 of DS treatment. During recovery, T lines recovered easily whereas 67% of WT plants failed to recover. In T lines, the rate of photosynthesis strongly and positively correlated with the transpiration rate ( r = 0.92), RWC ( r = 0.90), WP ( r = 0.86), and total chlorophyll content ( r = 0.75), suggesting its strong correlation with water retention-related parameters. Furthermore, yield parameters such as, pod weight and harvest index of T lines were up to 2.19 and 1.38 times more than those of WT plants, respectively. Thus, the significantly better performance of mtlD T peanut lines than of WT plants under DS could be attributed to the accumulation of mannitol, which in turn helped in maintaining the osmoregulation and ROS scavenging activity of mannitol and ultimately conferred water-economizing capacity and higher yield in T lines than in WT plants.

    Clinical management of Ebola virus disease remains challenging. Routine laboratory analytics are often unavailable in the outbreak setting, and few data exist for the associated haematological and biochemical abnormalities. We aimed to assess laboratory and clinical data from patients with Ebola virus disease to better inform clinical management algorithms, improve understanding of key variables associated with outcome, and provide insight into the pathophysiology of Ebola virus disease. We recruited all patients, alive on arrival, with confirmed Ebola virus disease who were admitted to the Kerry Town Ebola treatment centre in Sierra Leone. At admission, all patients had clinical presentation recorded and blood taken for Ebola confirmation using reverse-transcriptase-PCR (RT-PCR) and for haematological and biochemical analysis. We studied the association between these and clinical outcome. The primary outcome was discharge from the Ebola treatment centre. 150 patients were admitted to the treatment centre between Dec 8, 2014, and Jan 9, 2015. The mean age of patients was 26 years (SD 14·7). Case fatality rate was 37% (55/150). Most patients presented with stage 2 (gastrointestinal involvement, 72/118 [61%]) and stage 3 (severe or complicated, 12/118 [10%]) disease. Acute kidney injury was common (52/104 [50%]), as were abnormal serum potassium (32/97 [33%]), severe hepatitis (54/92 [59%]), and raised C-reactive protein (21/100 [21%]). Haematological abnormalities were common, including raised haematocrit (15/100 [15%]), thrombocytopenia (47/104 [45%]), and granulocytosis (44/104 [42%]). Severe acute kidney injury, low RT-PCR cycle threshold (Ebola virus disease is associated with a high prevalence of haematological and biochemical abnormalities, even in mild disease and in the absence of gastrointestinal symptoms. Clinical care that targets hypovolaemia, electrolyte disturbance, and acute kidney injury is likely to reduce historically high case fatality rates

    Nowadays quality plays a vital role in all the products. Hence, the development in manufacturing process focuses on the fabrication of composite with high dimensional accuracy and also incurring low manufacturing cost. In this work, an investigation on machining parameters has been performed on jute-flax hybrid composite. Here, the two important responses characteristics like surface roughness and material removal rate are optimized by employing 3 machining input parameters. The input variables considered are drill bit diameter, spindle speed and feed rate. Machining is done on CNC vertical drilling machine at different levels of drilling parameters. Taguchi’s L16 orthogonal array is used for optimizing individual tool parameters. Analysis Of Variance is used to find the significance of individual parameters. The simultaneous optimization of the process parameters is done by grey relational analysis. The results of this investigation shows that, spindle speed and drill bit diameter have most effect on material removal rate and surface roughness followed by feed rate.

    The effect of excretion-secretion products (ESP) of five abundant fouling invertebrate species (bivalve mollusks Hiatella arctica and Mytilus edulis, solitary ascidia Styela rustica, sponge Halichondria panicea, and sea starAsterias rubens, inhabiting the White Sea) on the biochemical status of blue mussel M. edulis was assessed by the dynamics of lysosomal enzymes activity (nucleases, glycoside hydrolases, and cathepsins). ESP of conspecific species had no effect on the metabolism of the mollusks of this species. ESP of A. rubens, S. rustica, and H. panicea activated the same enzymes. First, acid RNase and glycoside hydrolases activity increased, but in different ways. The metabolites of H. arctica affected the activity of proteometabolism enzymes.

    New relations which connect cross sections with neutral current parameters have been obtained in deep inelastic and (quasi-)elastic ν(ν-bar)N, e ± (μ ± )N scattering. The relations are independent of the structure functions and formfactors of the nucleon. A known example is the Paschos-Wolfenstein relation in ν(ν-bar)N scattering. The relations have been obtained with allowance for the contribution of the extra Z' bozon which makes it possible to use them both for extractions of the standard model parameters (ρ, sin 2 Θ W ) and for the search for some manifestations of new physics. 21 refs.; 1 tab

    The study introduced anti-hyperglycemic influence of aqueous extract of Ocimum basilicum seeds (AEOBS) in Streptozotocin (STZ) induced diabetic rats and estimating its potential to ameliorate altered level of biochemical parameters, serum electrolytes level and haematological indices along with its effect on body weight of treated rats. The albino rats were selected to observe oral glucose tolerance test by oral intake of aq. glucose solution (4g/kg, body weight) in normal rats and estimation of blood glucose level after administration of AEOBS at 250mg/kg, 500mg/kg and standard drug glibenclamide at 0.6mg/kg, body weight. Antidiabetic activity was evaluated in chronic study models by STZ induced diabetes in rats followed by blood glucose estimation. Chronic study model was selected to carry out further studies to evaluate the effect of AEOBS at 250mg/kg, 500mg/kg and standard drug on body weight, alterations in biochemical parameters including AST, ALT, ALP, total bilirubin and total protein, alterations in serum electrolytes like Na + , K + , Cl - , HCO 3 - along with estimation of haematological indices like red blood cells (RBC), white blood cells (WBC), hemoglobin (Hb), lymphocytes, neutrophils, eosinophils, monocytes and basophils. AEOBS significantly reduced the blood glucose level of diabetic rats at both doses. Body weight was also improved significantly. Similarly, the levels of biochemical parameters, serum electrolytes, and haematological indices were significantly ameliorated at both doses of AEOBS. The histopathological results revealed reconstitution of pancreatic islets towards normal cellular architecture in rats treated with AEOBS. The results illustrated that AEOBS have eminent antidiabetic potential in STZ effectuated diabetes in rats and can be extensively used for the treatment of diabetes mellitus-II and its associated complications including anaemia, diabetic nephropathy, liver dysfunction, and immunosuppression.

    Spodoptera frugiperda is the principal corn pest in Brazil. Searches for new control methods that minimize the adverse effects of synthetic insecticides have initiated a resurgence of the use of botanical insecticides. Citronella oil (a product of Cymbopogon winterianus) is an effective repellent and insecticide. Thus, biochemical profile changes in oil-treated larvae and its influence on reproduction were assessed. Corn leaves dipped in a 50mg/mL concentration were offered to third instar larvae for 24h and assessed in sixth instar to estimate protein, lipid, sugar, and glycogen levels. Adult testes and ovarioles were collected for histological and histochemical analysis 24h after emergence. Number of eggs and hatching rate were also measured. Oil-treated larvae showed an increase in glycogen and a decrease in protein, lipid, and totals sugar content. Control testes exhibited connective tissue lining and cysts with abundant spermatozoids. However, intense peripheral vacuolation and neutral carbohydrates reduction occurred in oil-treated individuals. Control ovarioles showed normal morphologic characteristics. On the other hand, oil-treatment ovarioles showed follicular cell stratification and removal, reduced nurse cell development, reduced yolk quantity, a thinner conjunctiva sheath, and a reduction in proteins and neutral carbohydrates. Eggs derived from oil-treated pairs were unviable. Therefore, sub-lethal doses of citronella oil alters the biochemical profile of S. frugiperda larvae, causing damage to their reproductive histophysiology and results in diminished reproduction or reproductive failure.

    Full Text Available Background. Gallium (Ga is used as radioimaging in diagnosis of cancers and also as a chemotherapeutic agent in the treatment of cancers. It is believed that gallium may interfere with iron metabolism and reduce cell growth in cancer tissues. Methods. Gallium as Ga-nitrate was injected daily to male rats. Animals were killed and sera were collected at indicated time. Serum iron parameters were determined spectrophotometrically. Transferring in complex with Ga was isolated and purified using immunoaffinity chromatography techniques. Results. Data found from immunoaffinity technique showed that Ga in the serum was bound to transferring, an iron carrier protein. Daily administration of Ga (50mg/kg as Ga-nitrate for 10 days reduced serum levels of iron, TIBC, Hb and Hct by 57, 37, 30 and 29 percent respectively, suggesting the reduction of transferring saturation by 30 percent. Significant reductions in the above parameters was also seen where Ga (10mg/kg was injected daily for 30 and 60 days. Discussion. Results obtained from present study indicated that gallium might be able to interfere with iron metabolism. More investigation is needed to elucidate the exact mechanism by which gallium undertakes its role in the cells with intercellular iron biochemical pathways.

    Leaves of three different sweet basil (Ocimum basilicum L.) cultivars (Italico a foglia larga, Cammeo, and Italiano classico) packed in macro-perforated polyethylene bags were stored at chilling (4°C) or non-chilling temperature (12°C) for 9days. During storage, visual quality, physiological (respiration rate, ethylene production, ammonium content) and chemical (antioxidant activity, total polyphenols and polyphenol profile) parameters were measured. Detached leaves stored at chilling temperature showed visual symptoms related to chilling injury, while ethylene production and ammonium content resulted associated to cultivar sensibility to damage at low temperature. Storage at 4°C caused a depletion in polyphenols content and antioxidant capability, which was preserved at 12°C. Regarding the polyphenols profile, stressful storage conditions did not enhance the phenolic metabolism. However, leaves stored at 12°C did not loss a significant amount of metabolites respect to fresh leaves, suggesting the possibility to extend the storability after the expiration date, for a possible recovery of bioactive compounds.

    Eleven-day-old female Mule ducks (Cairina moschata x Anas platyrhynchos) were individually infected per os with a single inoculation containing 10(4), 10(5) or 10(6) sporulated oocysts of E mulardi, or kept as uninfected controls. No mortality was observed. Growth rate was not modified at lower doses, but was reduced in the other 2 groups, with weight loss on d 7 post inoculation (PI). Blood was detected in feces by chemical characterization of hemoglobin as early as d 3 PI with the highest infecting dose, while oocyst excretion began on d 6 PI in all infected groups. With 10(5) and 10(6) oocysts, the authors observed a significant increase in sedimentation rate and a slight anemia. Total protein and lipid concentrations in the plasma decreased in the 3 infected groups. These results show the pathogenic effect of E mulardi in Mule duckling, with dose-dependent changes. All parameters, except sedimentation rate, showed maximal variations during the acute phase of infection, between d 6 and d 9 PI, and returned to normal values early, in relation to the infecting dose, except that the weight remained lower than in the uninfected group at the final control (d 28 Pl). These perturbations have been described in avian coccidiosis.

    This study aimed to examine the relationship between changes in systemic vitamin B12 concentrations with pro-inflammatory cytokines, anthropometric factors and biochemical markers of cardiometabolic risk in a Saudi population. A total of 364 subjects (224 children, age: 12.99 ± 2.73 (mean ± SD) years; BMI: 20.07 ± 4.92 kg/m² and 140 adults, age: 41.87 ± 8.82 years; BMI: 31.65 ± 5.77 kg/m²) were studied. Fasting blood, anthropometric and biochemical data were collected. Serum cytokines were quantified using multiplex assay kits and B12 concentrations were measured using immunoassay analyzer. Vitamin B12 was negatively associated with TNF-α (r = -0.14, p vitamin B12 was negatively associated with serum resistin (r = -0.160, p vitamin B12 was negatively associated with TNF-α (r = -0.242, p vitamin B12 in all subjects (r² = -0.17, p B12 in adults (r² = -0.78, p vitamin B12 concentrations were associated with pro-inflammatory cytokines and biochemical markers of cardiometabolic risks in adults. Maintaining adequate vitamin B12 concentrations may lower inflammation-induced cardiometabolic risk in the Saudi adult population.

    Full Text Available The instrumented-Timed-Up-and-Go test (iTUG provides detailed information about the following movement patterns: sit-to-walk (siwa, straight walking, turning and walk-to-sit (wasi. We were interested in the relative contributions of respective iTUG sub-phases to specific clinical deficits most relevant for daily life in Parkinson's disease (PD. More specifically, we investigated which condition-fast speed (FS or convenient speed (CS-differentiates best between mild- to moderate-stage PD patients and controls, which parameters of the iTUG sub-phases are significantly different between PD patients and controls, and how the iTUG parameters associate with cognitive parameters (with particular focus on cognitive flexibility and working memory and Health-Related-Quality of Life (HRQoL.Twenty-eight PD participants (65.1 ± 7.1 years, H&Y stage 1-3, medication OFF state and 20 controls (66.1 ± 7.5 years performed an iTUG (DynaPort®, McRoberts BV, The Netherlands under CS and FS conditions. The PD Questionnaire 39 (PDQ-39 was employed to assess HRQoL. General cognitive and executive functions were assessed using the Montreal Cognitive Assessment and the Trail Making Test.The total iTUG duration and sub-phases durations under FS condition differentiated PD patients slightly better from controls, compared to the CS condition. The following sub-phases were responsible for the observed longer total duration PD patients needed to perform the iTUG: siwa, turn and wasi. None of the iTUG parameters correlated relevantly with general cognitive function. Turning duration and wasi maximum flexion velocity correlated strongest with executive function. Walking back duration correlated strongest with HRQoL.This study confirms that mild- to moderate-stage PD patients need more time to perform the iTUG than controls, and adds the following aspects to current literature: FS may be more powerful than CS to delineate subtle movement deficits in mild- to moderate-stage PD

    The abuse of morphine has risen considerably in recent years, mainly due to the increase of its prescription in clinical medicine. Also, increased consumption of processed foods, rich in trans fatty acids (TFA), has caused concerns about human health. Thus, the aim of our study was to determine whether trans fat consumption in the perinatal period may affect preference for morphine in adolescent female and male rats. Dams were orally supplemented with water (C-control) or hydrogenated vegetable fat (HVF-rich in TFA) during gestation and lactation periods. On post-natal day 43, pups were exposed to morphine (4mg/kg i.p., for 4 days) and assessed in the conditioned place preference paradigm. Anxiety-like symptoms were assessed, and oxidative status of the brain was estimated by reactive species (RS) generation. Female rats with HVF supplementation showed increased morphine preference and less anxiety-like symptoms. Additionally, both male and female rats from HVF-supplementation showed increased RS generation in the ventral tegmental area, whose level was similar in morphine-conditioned female rats. RS generation was increased in the hippocampus of morphine-conditioned female rats, regardless of the supplementation of their dams. We may infer that gender is a predictive factor to opioid preference, since adolescent female rats showed more susceptibility to addiction than males. Furthermore, trans fat consumption across the perinatal period is able to modify parameters of opioid preference in female rats, possibly due to TFA incorporation in phospholipid membranes, modifying the endogenous opioid system and the oxidative status in brain areas related to drug addiction.

    This contribution reports the effects of Moringa oleifera leaves (MOLs) meal on the growth performances, nutrient digestibility, carcass trait, meat quality, antioxidant capacity and biochemical parameters of growing New Zealand white rabbits. The MOL was substituted for alfalfa meal at levels of 0, 10%, 20% and 30% to obtain respective diets MOL0, MOL10, MOL20 and MOL30. Each treatment was replicated five times with 10 rabbits per replicate. Results showed the average daily weight gain (ADWG) and feed conversion ratio (FCR) of rabbits fed MOL20 diet were significantly better (p oleifera leaves (MOL0, MOL10). The meat drip loss of rabbits fed with diet MOL10 was significantly lower (p oleifera leaves. No significant differences were found in the digestibility of crude fibre (CF), crude fat (EE), ash, crude protein (CP) and nitrogen-free extract (NFE) among the dietary groups. Moringa oleifera leaves also have a significant impact on serum albumin (ALB), low-density lipoprotein cholesterol (LDLC), triiodothyroxine (T 3 ) and tetraiodothyroxine (T 4 ) values and the activity of superoxide dismutase (SOD) and catalase (CAT) in serum and liver. The results indicated that M. oleifera leaves could be developed as a good feed source, and it not only could substitute for alfalfa meal well but also has a significant effect on growth performance, meat quality, antioxidant and biochemical parameters of rabbits. © 2017 Blackwell Verlag GmbH.

    Advancement in materials synthesis largely depends up on their diverse applications and commercialisation. Antifungal effects of phytogenic silver nanoparticles (AgNPs) were evident, but the reports on the effects of the same on agricultural crops are scant. Herein, we report for the first time, size dependent effects of phytogenic AgNPs (synthesised using Stevia rebaudiana leaf extract) on the germination, growth and biochemical parameters of three important agricultural crops viz., rice ( Oryza sativa L), maize ( Zea mays L) and peanut ( Arachis hypogaea L). AgNPs with varied sizes were prepared by changing the concentration and quantity of the Stevia rebaudiana leaf extract. As prepared AgNPs were characterized using the techniques, such as high-resolution transmission electron microscopy, particle size and zeta potential analyser. The measured (dynamic light scattering technique) average sizes of particles are ranging from 68.5 to 116 nm. Fourier transform infrared studies confirmed the participation of alcohols, aldehydes and amides in the reduction and stabilisation of the AgNPs. Application of these AgNPs to three agricultural crop seeds (rice, maize and peanut) resulted in size dependent effects on their germination, growth and biochemical parameters such as, chlorophyll content, carotenoid and protein content. Further, antifungal activity of AgNPs also evaluated against fungi, Aspergillus niger .

    2008-01-01

    In order to establish the relationships between macroseismic and instrumental parameters, macroseismic field of 28 historical earthquakes that produced great effects in the Colombian territory were studied. The integration of the parameters was made by using the methodology of Kaussel and Ramirez (1992), for great Chilean earthquakes; Kanamori and Anderson (1975) and Coppersmith and Well (1994) for world-wide earthquakes. Once determined the macroseismic and instrumental parameters it was come to establish the model of the source of each earthquake, with which the data base of these parameters was completed. For each earthquake parameters related to the local and normal macroseismic epicenter were complemented, depth of the local and normal center, horizontal extension of both centers, vertical extension of the normal center, model of the source, area of rupture. The obtained empirical relations from linear equations, even show behaviors very similar to the found ones by other authors for other regions of the world and to world-wide level. The results of this work allow establishing that certain mutual non compatibility exists between the area of rupture and the length of rupture determined by the macroseismic methods, with parameters found with instrumental data like seismic moment, Ms magnitude and Mw magnitude.

    Gelidium corneum (Hudson) J.V. Lamouroux is a very important primary producer in the Cantabrian coastal ecosystem. Some local declines in their populations have been recently detected in the Basque coast. Occurrences of yellowing and an unusual branch breakdown pattern have also been reported for some G. corneum populations. In order to gain further insight into those environmental stressors operating at a local scale, here we investigate if shallow subtidal populations of G. corneum living under potentially different conditions of irradiance (PAR and UVA) and water temperature exhibit differences in some biochemical indicators of stress, namely C:N, antioxidant activity (radical cation of 2,2‧-azino-bis (3-ethylbenzothiazoline-6-sulfonate); ABTS+ assay) and mycosporine-like amino acids (MAAs) (Asterine 330 and Palythine). We hypothesised that G. corneum subjected to higher ambient levels of irradiance and water temperature would show higher C:N ratios, lower antioxidant activity and higher MAA concentrations. Our results partially support this hypothesis. We found that G. corneum exposed to increased levels of irradiance (PAR, UVA) exhibited greater C:N ratios and lower antioxidant activity (higher IC50), whereas no relationship was found regarding MAAs. No differences in biochemical performance in relation to temperature were detected among G. corneum exposed to comparable high light. Similarly, G. corneum growing under lower UVA radiation levels showed no differences in any of the measured biochemical variables with regard to PAR and water temperature. These findings suggest that, among the environmental factors examined, UVA radiation may be an important driver in regulating the along-shore variation in G. corneum biochemical performance. Therefore, the role of irradiance, especially UV radiation, in potential future alterations in Cantabrian G. corneum populations cannot be ruled out as a potential underlying factor.

    Full Text Available Background: This study was conducted to determine the efficacy of milk thistle seeds (MTSs in counteracting the toxic effects of aflatoxin B1 (AFB1 in a contaminated diet fed to broilers. Methods: Two dietary inclusion rates of AFB1 (0, 0.250 and 500 ppb and MTS (0, 0.5 and 1% were tested in a 3×3 factorial manner. The effect of nine experimental treatments was assessed using 216 one-d-old Ross 308 male broiler chicks in a randomized complete design with 4 replicates of 6 birds each from one to 21 days of age. The effects of dietary AFB1 and MTS on serum biochemistry factors, antibody titer against Newcastle disease (ND and influenza disease (ID in broilers were evaluated at the end of this period. Results: Statistical analysis of the main effects of diets indicated no significant changes in uric acid, cholesterol, triglycerides, low density lipoprotein (LDL, ID, and phosphorus compared to the control (P>0.01. Also, addition of 500 ppb of dietary AFB1 into the diet was associated with significant decreases in serum glucose, calcium, high density lipoprotein (HDL, and ND compared to the control group (P<0.01. The contaminated diet significantly increased the activities of aspartate aminotransferase (AST and alanine aminotransferase (ALT (P<0.05. Conclusion: Milk thistle showed protective effects and resulted in some serum enzyme activities and serum biochemical changes associated with aflatoxin toxicity.

    This experiment aimed to evaluate the effect of calcium soap of fatty acid (CSFA) supplementation on serum biochemical and hormones and ovarian activity during out-of-the-breeding season in ewes. Twelve crossbred ewes, 2-3 years of age and weighting 45–55 kg, were allocated into two equal groups. The first group was control and the other was treated with 50 g/head of CSFA. All ewes were fed basal diet and treated with 60 mg of medroxy progesterone acetate intravaginal sponge for 12 day. At the third day of sponge removal, the CSFA-treated group was given 50 g/head of CSFA daily for two estrous cycles. During the estrus phase, ovarian activity was detected using ultrasonography in both groups. All ewes were then subjected to natural breeding and conception rate. Blood samples were collected from all ewes during treatment period. Results revealed significant (P < 0.05) increases in serum cholesterol, triglycerides, low-density lipoprotein cholesterol, glucose, and progesterone levels with decrease in calcium and phosphorous levels in treated group. In treated group, normal-size ovaries and more than one follicle on the ovaries were detected and pregnancy rate increased. In conclusion, CSFA supplementation was effective to maintain the reproductive performance when ewes were out of the breeding season. PMID:22629155

    Full Text Available In order to investigate the effect of physical forms of starter diets on performance, weaning age, nutrient digestibility and rumen biochemical factors, 24 female of neonatal Brown Swiss calves (average body weight of 39.5±1.2 kg were randomly assigned to three treatments. Dietary treatments were mashed (MS, pelleted (PS, and texturized (TS starter using 8 calves from birth till 90 days of age in each treatment. Diets were formulated to be iso-nitrogenous with 21% crude protein. Based on the experimental results, calves that received PS and TS diets, had significant higher average daily gain (ADG than those receiving MS (p0.05. Ruminal pH was higher (p<0.01 in MS than the other groups, but ruminal ammonia (g/dl concentration was not different among the treatments. Body measurements such as body length, pin width, hip width, pin to hip length, size of metacarpus and metatarsus bones, hip height, wither height, stomach size and heart girth were not significantly different among the treatments. Overall, it is concluded that starter diets in the form of pellet and texture can improve performance in neonatal Brown Swiss calves compared to the mashed form.

    This is a preliminary study of a specific nutritional supplement -Supportan(®) - for the clinical support of patients with locally advanced head and neck (H&N) cancers who underwent treatment with concurrent radiochemotherapy (RT-CHT). Seven patients received nutritional supplement (Supportan(®)) plus habitual diet during a median time of treatment with RT on 7.8 weeks plus concurrent weekly CHT(S). Specific serum protein fractions as a potential useful tool to evaluate the nutritional status were determined. The main objective was to assess the compliance with the above-mentioned treatment. Patients completed the nutritional support, 5 / 7 patients via oral route and 2/7 patients through nasogastric tube. All studied patients, that completed treatment, had not severe mucositis -ulcera, hemrraghe and/ or infection. None of them had another severe toxicity by treatment nor had impairment of Pefomance Status. No differences in all specific sera proteins were observed between S and To. In this preliminary study of few patients, we have observed a potential usefulness of Supportan(®) in the compliance of concurrent RT-CHT in patients with H&N cancers; moreover, its administration was useful to maintain the initial biochemical nutritional profile.

    The attempt of this paper is to present an effective approach for the optimization of the shot peening process of welded AISI 304 austenitic stainless steel with multi performance characteristics using Grey relational analysis (GRA) based on Taguchi orthogonal array. Twenty-seven experimental runs are performed to determine best process parameters level. An analysis of variance (ANOVA) is carried out to identify significant peening parameters. The response tables are obtained for analyzing the optimal levels of shot peening parameters and major factors that affect the quality function. The multiple performance characteristics including tensile strength, surface hardness and surface roughness are the quality functions considered for the optimization. Further mathematical models are developed using regression analysis for the tensile strength, surface hardness and surface roughness. It will be very helpful to the engineers in deciding the levels of the shot peening parameters for desired performance characteristics

    Full Text Available Carcass composition in reindeer is affected by feed intake and the age and sex of the animal. Studies have also shown that age, sex, carcass trim fat content and total intramuscular fat content (IMF influence lipid class composition. The aim of this study was to compare lipid class composition and IMF in relation to carcass weight, conformation and trim fat content, and to investigate how these parameters are affected by age, sex and different feed sources. Five groups of reindeer were studied. Two groups of calves were fed two grain-based pelleted feeds with different lipid compositions for approximately two months before slaughter. One of these groups was fed with conventional pellets, and the other with pellets enriched with linseed cake to increase the amount of n-3 fatty acids in the diet. Three groups of grazing reindeer were also included in the study, consisting of adult males, adult females or calves. Reindeer calves fed pellets had higher slaughter weights, higher trim fat content and better carcass conformation scores compared to the grazing calves. However, there was no significant difference in IMF between pellet-fed and grazing calves. Adult female reindeer had the highest and grazing calves the lowest slaughter weights, trim fat and IMF. There was no difference in lipid class composition in meat from calves fed with the two pelleted feeds, whereas grazing calves had a higher amount of phospholipids. Squalene was identified and quantified as a component of intramuscular lipids in reindeer meat. Effekt av produktionssystem, ålder och kön på slaktkroppskvalitet och några biokemiska egenskaper hos renköttAbstract in Swedish / Sammandrag: Slaktkroppssammansättningen hos renar påverkas av både foderintag, fodersammansättning och djurens ålder och kön.

    Agro-Land Surface Models (agro-LSM) have been developed from the coupling of specific crop models and large-scale generic vegetation models. They aim at accounting for the spatial distribution and variability of energy, water and carbon fluxes within soil-vegetation-atmosphere continuum with a particular emphasis on how crop phenology and agricultural management practice influence the turbulent fluxes exchanged with the atmosphere, and the underlying water and carbon pools. A part of the uncertainty in these models is related to the many parameters included in the models' equations. In this study, we quantify the parameter-based uncertainty in the simulation of sugar cane biomass production with the agro-LSM ORCHIDEE-STICS on a multi-regional approach with data from sites in Australia, La Reunion and Brazil. First, the main source of uncertainty for the output variables NPP, GPP, and sensible heat flux (SH) is determined through a screening of the main parameters of the model on a multi-site basis leading to the selection of a subset of most sensitive parameters causing most of the uncertainty. In a second step, a sensitivity analysis is carried out on the parameters selected from the screening analysis at a regional scale. For this, a Monte-Carlo sampling method associated with the calculation of Partial Ranked Correlation Coefficients is used. First, we quantify the sensitivity of the output variables to individual input parameters on a regional scale for two regions of intensive sugar cane cultivation in Australia and Brazil. Then, we quantify the overall uncertainty in the simulation's outputs propagated from the uncertainty in the input parameters. Seven parameters are identified by the screening procedure as driving most of the uncertainty in the agro-LSM ORCHIDEE-STICS model output at all sites. These parameters control photosynthesis (optimal temperature of photosynthesis, optimal carboxylation rate), radiation interception (extinction coefficient), root

    Although men presenting with clinically localized prostate cancer (PrCA) often are treated with radical prostatectomy or radiation therapy with curative intent, about 25-40% develop biochemically recurrent PrCA within 5 years of treatment, which has no known cure. Studies suggest that carotenoid and tocopherol intake may be associated with PrCA risk and progression. We examined plasma carotenoid and tocopherol levels in relation to prostate-specific antigen (PSA) levels among men with PSA-defined biochemical recurrence of PrCA. Data analyzed were from a 6-month diet, physical activity and stress-reduction intervention trial conducted in South Carolina among biochemically recurrent PrCA patients (n=39). Plasma carotenoids and tocopherol levels were measured using high-performance liquid chromatography (HPLC). Linear regression was used to estimate least-square means comparing PSA levels of men with high versus low carotenoid/tocopherol levels, adjusting for covariates. After adjusting for baseline PSA level, plasma cis-lutein/zeaxanthin level at 3 months was related inversely to PSA level at 3 months (P=0.0008), while α-tocopherol (P=0.01), β-cryptoxanthin (P=0.01), and all-trans-lycopene (P=0.004) levels at 3 months were related inversely to PSA levels at 6-months. Percent increase in α-tocopherol and trans-β-carotene levels from baseline to month 3 were associated with lower PSA levels at 3 and 6 months. Percent increase in β-cryptoxanthin, cis-lutein/zeaxanthin and all-trans-lycopene were associated with lower PSA levels at 6 months only. Certain plasma carotenoids and tocopherols were related inversely to PSA levels at various timepoints, suggesting that greater intake of foods containing these micronutrients might be beneficial to men with PSA-defined PrCA recurrence.

    Full Text Available Background: This study aimed to examine the relationship between changes in systemic vitamin B12 concentrations with pro-inflammatory cytokines, anthropometric factors and biochemical markers of cardiometabolic risk in a Saudi population. Methods: A total of 364 subjects (224 children, age: 12.99 ± 2.73 (mean ± SD years; BMI: 20.07 ± 4.92 kg/m2 and 140 adults, age: 41.87 ± 8.82 years; BMI: 31.65 ± 5.77 kg/m2 were studied. Fasting blood, anthropometric and biochemical data were collected. Serum cytokines were quantified using multiplex assay kits and B12 concentrations were measured using immunoassay analyzer. Results: Vitamin B12 was negatively associated with TNF-α (r = −0.14, p < 0.05, insulin (r = −0.230, p < 0.01 and HOMA-IR (r = −0.252, p < 0.01 in all subjects. In children, vitamin B12 was negatively associated with serum resistin (r = −0.160, p < 0.01, insulin (r = −0.248, p < 0.01, HOMA-IR (r = −0.261, p < 0.01. In adults, vitamin B12 was negatively associated with TNF-α (r = −0.242, p < 0.01 while positively associated with resistin (r = 0.248, p < 0.01. Serum resistin was the most significant predictor for circulating vitamin B12 in all subjects (r2 = −0.17, p < 0.05 and in children (r2 = −0.167, p < 0.01 while HDL-cholesterol was the predictor of B12 in adults (r2 = −0.78, p < 0.05. Conclusions: Serum vitamin B12 concentrations were associated with pro-inflammatory cytokines and biochemical markers of cardiometabolic risks in adults. Maintaining adequate vitamin B12 concentrations may lower inflammation-induced cardiometabolic risk in the Saudi adult population.

    A biological complex organism is involuntarily guided from all sides by measure and regulation systems. The human being is such a complex organism. Many cyclical processes are simultaneously at work, making it unclear how and why which process takes place at which moment. Noticeable examples are the 28-day menstrual cycle and the 40-week pregnancy. The time of activation in the middle of the menstrual is fairly clear. Hormonal changes also occur in this period. Why the hormonal changes occur, and what their relationship is with the activation of the processes is unclear. That is also the case during pregnancies. What is it that determines that a pregnancy should last an average of 40 weeks? What causes the changes in a complicated pregnancy? What are those changes? Prostaglandin concentrations have been found to have some relationship with these changes, but the activation of these changes and how to examine them is unknown. Using an example from practical experience, this article illustrates what Horrobin and Manku already reported in 1977, namely, the properties of prostaglandin E1 and 6-keto pgF1α: reversal effect with elevated concentration. The properties described is exceptionally suitable for the time of activation in a biochemically regulated measure and regulation system. These properties can help explain the occurrence of physiological cycles. The known electronic saw-tooth wave has a biochemical analogue with this. This paper describes the presumed relationship between hormones and the accompanying prostaglandins with the hormone effects based on what is known regarding their concentrations progress. This relationship reveals the practical consequences of the experimentally found sensitivity of biochemical effects with regard to the accompanying prostaglandins. This paper shows how the theoretical relationship between effects of oestrogens and progestagens result in a curve that comprise observable aspects of the Basal Body Temperature Curve. The

    The present study was conducted to investigate the effects of dietary dandelion extracts (DE) supplementation on growth performance, feed utilization, body composition, plasma biochemical indices, immune responses, hepatic antioxidant abilities, and resistance to the pathogen Vibrio harveyi in Trachinotus ovatus. A basal diet supplemented with DE at 0, 0.50, 1.00, 2.00, 4.00 and 10.00 g kg -1 were fed to golden pompano for 8 weeks. The study indicated that dietary supplementation with DE could significantly improve final body weight (FBW), weight gain rate (WGR), specific growth rate (SGR), feed efficiency ratio (FER), feed intake (FI), protein efficiency ratio (PER) and protein deposit rate (PDR) (P dietary DE (P dietary DE (P dietary DE showed significant increase in plasma total protein, complement 4 content and alkaline phosphatase, lysozyme, glutathione reductase (GSR) activity, but significant decrease in triglyceride, low density lipoprotein cholesterol, malondialdehyde (MDA) content and aspartate aminotransferase activities compared to the control group (P < 0.05). Hepatic antioxidant enzymes (SOD, T-AOC, CAT, GSH-Px, GSR) significantly increased whereas MDA content significantly decreased in fish fed 1.00 g kg -1 DE supplement (P < 0.05). After challenge with Vibrio harveyi, significant higher post-challenge survival was observed in fish fed DE supplement (P < 0.05). These results indicated that golden pompano fed a diet supplemented with DE (especially at 1.00 g kg -1 of fed supplement) could significantly promote its growth performance, feed utilization, body protein deposit, immune ability, hepatic and plasma antioxidative enzyme activities and improve its resistance to infection by Vibrio harveyi.

    Acerola contains high levels of vitamin C and rutin and shows the corresponding antioxidant properties. Oxidative stress on the other hand is an important factor in the development of obesity. In this study, we investigated the biochemical and antigenotoxic effects of acerola juice in different stages of maturity (unripe, ripe and industrial) and its main pharmacologically active components vitamin C and rutin, when given as food supplements to obese mice. Initial HPLC analyses confirmed that all types of acerola juice contained high levels of vitamin C and rutin. DPPH tests quantified the antioxidant properties of these juices and revealed higher antioxidant potentials compared to pure vitamin C and rutin. In an animal test series, groups of male mice were fed on a standard (STA) or a cafeteria (CAF) diet for 13 weeks. The latter consisted of a variety of supermarket products, rich in sugar and fat. This CAF diet increased the feed efficiency, but also induced glucose intolerance and DNA damage, which was established by comet assays and micronucleus tests. Subsequently, CAF mice were given additional diet supplements (acerola juice, vitamin C or rutin) for one month and the effects on bone marrow, peripheral blood, liver, kidney, and brain were examined. The results indicated that food supplementation with ripe or industrial acerola juice led to a partial reversal of the diet-induced DNA damage in the blood, kidney, liver and bone marrow. For unripe acerola juice food supplementation, beneficial effects were observed in blood, kidney and bone marrow. Food supplementation with vitamin C led to decreased DNA damage in kidney and liver, whereas rutin supplementation led to decreased DNA damage in all tissue samples observed. These results suggest that acerola juice helps to reduce oxidative stress and may decrease genotoxicity under obesogenic conditions. Copyright © 2014 Elsevier B.V. All rights reserved.

    Previous studies have shown that Spirulina platensis Gomont (Phormidiaceae) (SP) extract has beneficial effects on many disease conditions. The putative protective effects of SP were investigated in diabetic rats. The current study investigates the antioxidant effects of SP in diabetic Wistar rats. Alloxan monohydrate (150 mg/kg body weight) was intraperitoneally administrated to induce diabetes. An aqueous suspension of SP powder in distillate water (10% w/v) was administrated orally by gavage (1 mL/day) for 50 days. Histopathological, biochemical and antioxidant analyses were performed. Glycemia, liver function and HOMA-IR were assessed using Spinreact and ELISA kits. SP exhibited high-antioxidant activity. The IC 50 values of the SP aqueous extract were 70.40 and 45.69 mg/L compared to those of the standard antioxidant BHT, which were 27.97 and 19.77 mg/L, for the DPPH and ABTS tests, respectively. The diabetic animals showed a significant increase in glycaemia (from 4.05 to 4.28 g/L) and thiobarbituric acid reactive substances (50.17 mmol/g protein) levels. Treatment with SP significantly reduced glycaemia by 79% and liver function markers [glutamate pyruvate transaminase (GPT), glutamate oxaloacetate transaminase (GOT) and alkaline phosphatase (Alk-p)]) by 25, 36 and 20%, respectively, compared to that of the controls. There was a significant increase in superoxide dismutase (48%), total antioxidant status (43%), glutathione peroxidase (37%) and glutathione reductase (16%) in the diabetic rats treated with SP. These results showed that SP has high antioxidant activity, free radical scavenging, antihyperglycemic and hepatoprotective effects in diabetes.

    This study aimed at exploring the citation parameters of contact lenses articles published in the Ophthalmology thematic category of the Journal Citation Reports (JCR). The Thompson Reuters Web of Science database was accessed to record bibliometric information and citation parameters of all journals listed under the Ophthalmology area of the 2011 JCR edition, including the journals with main publication interests in the contact lens field. In addition, the same database was used to unveil all contact lens-related articles published in 2011 in the same thematic area, whereupon differences in citation parameters between those articles published in contact lens and non-contact lens-related journals were explored. Significant differences in some bibliometric indicators such as half-life and overall citation count were found between contact lens-related journals (shorter half-life and fewer citations) and the median values for the Ophthalmology thematic area of the JCR. Visual examination of all Ophthalmology journals uncovered a total of 156 contact lens-related articles, published in 28 different journals, with 27 articles each for Contact Lens & Anterior Eye, Eye & Contact Lens, and Optometry and Vision Science. Significant differences in citation parameters were encountered between those articles published in contact lens and non-contact lens source journals. These findings, which disclosed contact lenses to be a fertile area of research, may be of interest to researchers and institutions. Differences in bibliometric indicators are of relevance to avoid unwanted bias when conducting between- and within-discipline comparisons of articles, journals, and researchers.

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

    We conducted an in-depth analysis of the proteomic and biochemical profiles of the venom of neonate and adult short-tailed pit vipers (Gloydius brevicaudus). Identified proteins were assigned to a few main toxin families. Disintegrin, phospholipase A2 (PLA2), serine proteinase, cysteine-rich secretory protein, C-type lectin-like protein, l-amino acid oxidase and snake venom metalloproteinase (SVMP) were detected in both venoms, while 5'-nucleotidase was detected only in the adult venom. SVMP was the predominant protein family in both venoms (neonate: 65.7%; adult: 64.4%), followed by PLA2 (neonate: 13.4%; adult: 25.0%). Antivenomic analysis revealed that commercial G. brevicaudus antivenom almost neutralized the chromatographic peaks with medium and high molecular masses in both venoms, but did not completely recognize peaks with low molecular mass. Toxicological and enzymatic activities show remarkable age-related variation in G. brevicaudus venom, probably resulting from variation in venom composition. Our data demonstrate age-related variation across venomics, antivenomics and biochemical profiles of G. brevicaudus venom, and have implications for the management of G. brevicaudus bites, including improving antivenom preparation by combining both venoms. This study investigates the composition and biochemical activity of neonate and adult Gloydius brevicaudus venoms. We found remarkable age-related variation in venom biological activity, likely the result of variation in venom composition. Antivenomics analysis was used to explore difference in neonate and adult G. brevicaudus venoms. Our findings have implications for the diagnosis and clinical management of G. b
