    This study describes the suitability of the biological radiation indicator 'amylase in human blood serum' to identify, if previous irradiation has occurred. After 'in vivo' exposure, of the human body with organ doses > 0,5 Gy, high activities of the enzyme are found in serum. The important results of examinations from different work groups and from own experiments were summarized in tabular form and evaluated from the statistic point of view. The results show that in more than 90% of all cases, the amylase system is suitable to identify exposure beyond 0,5 to 1 Gy, approximately. However, this is only possible if the salivary glands were also exposed and blood samples are taken about 18 hours after exposure. For the differentiation between induced increase of amylase from disease and radiation induced increase, it is recommended to carry out the isoamylase test, which makes it possible to distinguish between the individual enzymes. The assessment of the total amylase is appropriate to detect, with a range of significance of P = 0,05 that radiation exposure has occurred. The increase of activity is dose dependent when the salivary glands lie in the radiation field, however, the variations of activity are very high. Therefore the radiation dose cannot be considered. Only in cases where a very high radiation induced increase of activity is observed, a rough estimation of dose at the parotid glands can be made. (orig./MG) [de

    Full Text Available The article presents the results of research on the influence of the developed complex preparation Metisevit on the dynamics of morphological and biochemical blood indicators of piglets under nitrate loading. The research established that sodium nitrate intoxication causes disbalance of the physiological level of hematological indicators of the tested animals’ organisms. This was indicated by the manifestations of subclinical chronic nitrate-nitrite toxicosis: the increase in the level of nitrates, nitrites and methemoglobin in the blood. After prolonged feeding of the piglets with sodium nitrate at a dose of 0.3 g nitrate ion/kg, the concentration of nitrates and nitrites in the blood serum reached its maximum on the 60th day of the experiment. Also, the number of leukocytes and erythrocytes in the blood increased, and the activity of aspartate- and alanineaminotransferase in the blood serum increased. We rank the extent of liver intoxication with nitrates according to intensity of aminotransferase in the blood serum of the tested piglets. The normalization of morphological and biochemical blood indicators of piglets under nitrate-nitrite intoxication requires usage of a preparation which contains vitamins, zeolites and antioxidants. If the fodder contains high doses of nitrates, 1.0 mg/kg dose of Metisevit is added to the fodder for preventing subclinical nitrate-nitrite toxicosis. Metisevit contains the following agents: phenozan acid, methionine, zeolite, selenium, vitamins E and C. The research conducted proved the feasibility of using Metisevit for preventing chronic nitrate-nitrite toxicosis in piglets. This preparation caused a decrease in the concentration of nitrates, nitrites and in the level of methemoglobin in the blood of piglets. Usage of Metisevit on piglets showed normalization of the number of erythrocytes and hemoglobin in the blood on the 10th day, and normalization of ASAT and ALAT on 30th and 90th days.

    Full Text Available The article gives the results of the research on the influence of a developed complex liposomal preparation on the dynamics of morphological and biochemical indicators of the blood of rats subjected to modeled oxidative stress caused by intermuscular injection of 50% carbon tetrachloride at a dose of 0.25 ml per 100 g of body mass. We found that in conditions of intoxication by carbon tetrachloride, the physiological level of hematological indicators of the researched animals’ body was disrupted. This is indicated by the reduction in the amount of erythrocytes, hemoglobin content, concentration of hemoglobin per erythrocyte, increase in the amount of leucocytes, mass of hemoglobin per erythrocyte and increase of colour indicator. Also, we detected suppression of protein synthesis function of the liver. The levels of total protein and albumin fraction were below the normal physiological level. High indicators were observed in the levels of creatinine, urea and total bilirubin. In order to normalize the functional state of the liver under oxidative stress it is reasonable to use a liposomal preparation which contains butafosfan, interferon, thistle and vitamins. In order to normalize morphological and biochemical indicators of the blood of rats subject to intoxication of carbon tetrachloride it is reasonable to use a liposomal preparation that contains butafosfan, selenium, thistle, methionine and vitamins. Using the liposomal preparation Butaselmevit for rats under oxidative stress the morphological and biochemical indicators in the blood normalized. On the 14th day the indictors of the number of erythrocytes, the hemoglobin content, the white blood cell count and red blood indexes compared to control came within the physiological indicators, indicating a recovery of hematopoietic function of the bone marrow and normalized indicators of the functional state of the liver.

    Full text: An attempt was made to determine the effect of irradiation of eggs by low dose ionising radiation before incubation on concentration of total protein, glucose and cholesterol in the blood plasma of chickens hatched from irradiated eggs. The eggs of heavy breeding chickens were irradiated by dose of 0.15 Gy gamma radiation ( 60 Co) before incubation. Along with the chickens which were hatched from irradiated eggs, there was the control group of chickens hatched from nonirradiated eggs. All other conditions were the same for the both groups. After hatching, blood samples were taken from the wing vein on days 1, 3, 5, 7, 10, 20, 30 and 42. The concentration of all three parameters was determined spectrophotometrically using Boehringer Mannheim GmbH optimized kits. The concentration of total protein was significantly decreased in the blood plasma of chickens hatched from irradiated eggs on days 3, 7 and 30 and increased only on day 5. The concentration of glucose in the blood plasma was increased in the same chickens on days 1 and 30. The concentration of the cholesterol was decreased in the same chickens on day 7, and increased on day 10. Obtained results indicate that low-dose of gamma radiation has effects on some metabolic processes in the chickens hatched from eggs irradiated before incubation. (author)

    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.

    The blood pressure-lowering effect of dairy products holds the potential to decrease the risk of cardiovascular disease (CVD). An open question is if the successful expression of functional properties of the probiotic strain depends on host biomarkers and/or food matrix properties. The probiotic Lactobacillus plantarum strain TENSIA® (DSM 21380) is a novel microorganism with antimicrobial and antihypertensive functional properties. The aim of this study was to characterise the functional properties of the probiotic L. plantarum TENSIA and compare its effects on host anthropometric, clinical, and blood biomarkers when consumed with cheese or yoghurt. This study involved two double-blinded randomised placebo-controlled exploratory trials (ISRCTN15061552 and ISRCTN79645828) of healthy adults over a three-week period. The three-week consumption of probiotic L. plantarum TENSIA in a daily dose of 1×1010 cfu in probiotic cheese or a daily dose of 6×109 cfu in yoghurt with different content of carbohydrates, proteins, and lipids did not significantly change the body mass index (BMI), plasma glucose and lipid levels, or inflammatory markers in the blood. Reduced lowered systolic and diastolic blood pressure values were detected, regardless of food matrix or baseline values for blood pressure and BMI. In conclusion, our study showed that three-week consumption of the probiotic L. plantarum TENSIA either in cheese or yoghurt lowered diastolic and systolic blood pressure regardless of food matrix and baseline values of blood pressure and BMI, confirming the impact of the functional properties of the probiotic strain in decreasing CVD risk.

    Though patients with chronic fatigue syndrome (CFS) have lots of complaints, abnormal findings cannot be detected by biochemical screening tests. However, some specialized blood tests have revealed neuroendocrine immune axis abnormalities, which is closely associated with each other. Recent studies indicate that CFS can be understood as a special condition based on abnormality of the psycho-neuro-endocrino-immunological system, with the distinguishing feature of CFS seeming to be the secondary brain dysfunction caused by several cytokines and/or autoantibodies. In this paper, we summarize these abnormalities found in CFS and show the neuro-molecular mechanism leading to chronic fatigue.

    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.

    2009-09-01

    Full Text Available Abstract Background CTLA-4 was initially described as a membrane-bound molecule that inhibited lymphocyte activation by interacting with B7.1 and B7.2 molecules on antigen presenting cells. Alternative splicing of mRNA encoding the CTLA-4 receptor leads to the production of a molecule (sCTLA-4 that lacks a membrane anchor and is therefore secreted into the extracellular space. Despite studies finding that people with autoimmune disease more frequently express high levels of sCTLA-4 in their blood than apparently healthy people, the significance of these findings is unclear. Methods Molecules isolated from blood using CTLA-4 specific antibodies were analyzed with ligand binding assays, mass spectroscopy, and biochemical fractionation in an effort to increase our understanding of CTLA-4 immunoreactive material. Results Mass spectroscopy analysis of the molecules recognized by multiple CTLA-4-specific antibodies failed to identify any CTLA-4 protein. Even though these molecules bind to the CTLA-4 receptors B7.1 and B7.2, they also exhibit properties common to immunoglobulins. Conclusion We have identified molecules in blood that are recognized by CTLA-4 specific antibodies but also exhibit properties of immunoglobulins. Our data indicates that what has been called sCTLA-4 is not a direct product of the CTLA-4 gene, and that the CTLA-4 protein is not part of this molecule. These results may explain why the relationship of sCTLA-4 to immune system activity has been difficult to elucidate.

    Blood biochemical and hematology analyses are helpful indicators of the physiologic health of animals, particularly when making conservation and management decisions for threatened species. In this study, we 1) established blood biochemical reference intervals for two populations of threatened, free-ranging ornate box turtles ( Terrapene ornata) in northern Illinois during their active season and 2) examined the effects of individual carapace temperature ( T c ) on blood biochemical variables by using a Bayesian hierarchic framework. Individual blood variables differed throughout the active season (May-September 2015), but there were few distinct patterns in concentrations over time. When controlling for individual variability, blood biochemical variables potassium, sodium, chloride, ionized calcium, hematocrit (percentage of packed cell volume), and osmolality showed no effect of T c (i.e., slope estimates for these variables were not credibly different from zero) and had little individual variation. Glucose and blood urea nitrogen (BUN) were found to have slopes credibly different from zero, with glucose having an estimated positive slope and BUN having an estimated negative slope, suggesting different relationships in response to T c when controlling for individual variability. These physiologic blood data will serve as important baseline reference values for the clinical evaluation of wild ornate box turtles presented for veterinary care or for comparison to other studies of wild populations. Further, this study highlights the importance of considering individual-level effects (e.g., T c ) on physiologic health variables.

    This study investigated the effect of the biochemical and biophysical properties of the plasma membrane as well as membrane morphology on the susceptibility of human red blood cells to the cholesterol-dependent cytolysin pneumolysin, a key virulence factor of Streptococcus pneumoniae, using single cell studies. We show a correlation between the physical properties of the membrane (bending rigidity and surface and dipole electrostatic potentials) and the susceptibility of red blood cells to pneumolysin-induced hemolysis. We demonstrate that biochemical modifications of the membrane induced by oxidative stress, lipid scrambling, and artificial cell aging modulate the cell response to the toxin. We provide evidence that the diversity of response to pneumolysin in diabetic red blood cells correlates with levels of glycated hemoglobin and that the mechanical properties of the red blood cell plasma membrane are altered in diabetes. Finally, we show that diabetic red blood cells are more resistant to pneumolysin and the related toxin perfringolysin O relative to healthy red blood cells. Taken together, these studies indicate that the diversity of cell response to pneumolysin within a population of human red blood cells is influenced by the biophysical and biochemical status of the plasma membrane and the chemical and/or oxidative stress pre-history of the cell. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

    Full Text Available Abstract Background This study aimed to evaluate the clinical, haematological and biochemical responses to autologous blood transfusion and the feasibility of this practice in sheep. Thus, we used eight male, 8 months old sheep, weighing on average 30 kg, from which 15 mL/kg of whole blood was collected and stored in CPDA-1 bags. Blood samples were refrigerated for 8 days and subsequently re-infused. The clinical, haematological and biochemical parameters were evaluated before blood collection and reinfusion, after 10 minutes of collection and reinfusion, after 3, 6, 12, 24, 48, 96 and 192 hours after collection and reinfusion. Results With respect to clinical parameters, we observed a decrease in heart rate after 24, 48 and 196 hours from reinfusion compared to basal values (p p p p  Conclusion Autologous transfusion in sheep slightly altered the physiological, biochemical and haematological responses of sheep, indicating that the technique proposed is safe and can be applied in the clinical practice of this species. The 8 d period was not sufficient for complete recovery of the haematological parameters after blood collection.

  3. Biological and biochemical soil quality indicators for agricultural management

    2017-04-01

    Soil quality is defined as the capacity of a soil to perform multiple functions. Agricultural soils can, in principle, sustain a wide range of functions. However, negative pressure exerted by natural and anthropogenic soil threats such as soil erosion, soil organic matter losses and soil compaction have the potential to permanently damage soil quality. Soil chemical, physical and biological parameters can be used as indicators of soil quality. The specific objective of this study is to assess the suitability of novel soil parameters as soil quality indicators. We focus on biological/biochemical parameters, due to the unique role of soil biota in soil functions and to their high sensitivity to disturbances. The novel indicators are assessed in ten European long-term field experiments (LTEs) with different agricultural land use (arable and permanent crops), management regimes and pedo-climatic characteristics. The contrasts in agricultural management are represented by conventional/reduced tillage, organic/mineral fertilization and organic matter addition/no organic matter addition. We measured two different pools of labile organic carbon (dissolved organic carbon (DOC), and permanganate oxidizable carbon (POXC)), and determined DOC quality through its fractionation in hydrophobic and hydrophilic compounds. In addition, total nematode abundance has been assessed with qPCR. These parameters will be related to soil functions which have been measured with a minimum data set of indicators for soil quality (including TOC, macronutrients, and soil respiration). As a preliminary analysis, the Sensitivity Index (SI) for a given LTE was calculated for DOC and POXC according to Bolinder et al., 1999 as the ratio of the soil attribute under modified practices (e.g. reduced tillage) compared to the conventional practices (e.g. conventional tillage). The overall effect of the sustainable management on the indicators has been derived by calculating an average SI for those LTEs

    Some biochemical effects determined on human blood after addition of a gas mixture composed of oxygen (approximately 96%) and ozone (approximately 4%) have been evaluated. Ozone was used in a mild concentration ranging between 0.21 and 1.68 mM. Within few minutes after rapid mixing of the equal gas-liquid volumes, the ozone was consumed because by instantaneously reacting with biomolecules, generating reactive oxygen species (particularly hydrogen peroxide) having very short lifetime and lipid oxidation products. The following results are oxygen-ozone dose dependent: (1) The pO(2) values have risen from about 40 up to 400 mmHg. (2) By testing the highest ozone concentration, the total antioxidant capacity of blood decreased within 1 min from 1.35 to 0.91 mM but regained its normal values within 20 min owing to the rapid reduction of oxidized antioxidants operated by erythrocytes. (3) Similarly, intraerythrocytic reduced glutathione after ozonation decreased from the initial value of 5.71 to 4.56 micromol/g Hb. (4) Both hemolysis and methemoglobin showed a negligible increase.

    Full Text Available Respiratory diseases of cattle, particularly in young animals, represent the most important health and economic problem of cattle rearing. The aim of the present study was to evaluate the changes of selected blood indices in 25 calves aged 2–9 months suffering from etiologically undifferentiated chronic respiratory diseases. Blood samples were analysed for haematological indices and selected serum biochemistry variables. The results found in sick animals were compared with results from 25 healthy animals of the same age, housing and feeding system. Significant differences in means between the groups of clinically healthy and sick calves were found in 13 out of 24 evaluated indicators. In sick animals we found significantly higher mean concentrations of haemoglobin and total number of white blood cells (P P P P P P P P < 0.05. The presented results suggest the effect of respiratory diseases in calves on several changes of haematological and selected serum biochemical indicators. They indicate that respiratory diseases did not lead only to direct disturbance of gas exchange and acid-base balance, but they also indirectly affect some other variables of blood biochemistry.

  15. Effect of aspartame on biochemical and oxidative stress parameters in rat blood

    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.

    With the purpose of evaluating the applicability of several biological indicators in accidental overexposures a study was carried out in 20 patients undergoing therapeutical total body irradiation (TBI). The following parameters were evaluated: a) Oxidative stress indicators: erythrocyte superoxide dismutase (SOD) and catalase activity (CAT), lipo peroxyde levels (TBARS) and total plasma antioxidant activity (TAA). b) Haematological indicators: reticulocyte maturity index (RMI) and charges in lymphocyte subpopulations. Non significant changes in SOD and CAT activity were observed. Significant higher TBARS levels were found in patients with unfavorable post-BTM course without any significant correlation with TAA. RMI decreased early and dropped to zero in most of the patients and rose several days prior to reticulocyte, neutrophils and platelets counts. A significant decrease in absolute counts of all lymphocyte subpopulations was observed during TBI, particularly for B lymphocytes. A subpopulation of natural killer (NK) cells (CD16+/ CD 56 +) showed a relative higher radioresistance. Cytotoxic activity was significantly decreased after TBI. These data suggest that TBARS could provide an useful evolutive indicator in accidental over exposure d patients and RMI is an early indicator of bone marrow recovery after radioinduced aplasia. The implications of the different radiosensitivities within the NK subsets remains unanswered. (author) [es

    Full Text Available Metabolic disturbances associated with fluid and electrolyte imbalance, and changes in the synthetic functions of the liver are common complications of malaria and are dependent on the degree of parasitemia. Packed cell volume (PCV, random blood glucose (RBG, total bilirubin (TB, total proteins (TP, albumin, serum electrolytes [sodium (Na+, potassium (K+, chloride (Cl-, bicarbonate (HCO3-, calcium (Ca2+, magnesium (Mg2+] and anion gap (AG were determined in fifty children with malaria aged between 1-15 years and thirty age matched apparently healthy children without malaria, using colorimetric and flame photometric methods. Data was analyzed using t-test at p < 0.05. The PCV, RBG, Na+, Mg2+, AG and TP were significantly lower and Ca2+ and TB higher in children with malaria compared to children without malaria. The serum Na+, K+, AG, TP and albumin were significantly lower and Ca2+, HCO3- and TB higher in children with severe malaria compared to those with mild malaria. Malaria and high parasite density is associated with perturbations in homeostasis of proteins and electrolytes and these may be implicated in the deleterious consequences associated with malaria in children.

    2014-10-01

    Full Text Available The aim of the study was to determine the suitability of basic haematological, biochemical, and gasometric tests in checking the effectiveness of transfusion therapy in foals during isoerythrolysis. The number of red blood cells, haemoglobin, haematocrit, and partial pressure of carbon dioxide, oxygen, and blood pH was determined immediately before and several times after blood transfusion. The concentration of serum free bilirubin was also measured to confirm haemolysis. Fluids (0.9% NaCl, multielectrolytic fluid, 5% glucose and antibiotics (penicillin, amikacin were provided to the foals. The lowest values of haematological parameters were observed before transfusion. This was accompanied by decreased partial pressure of oxygen, low pH, and increased arterial carbon dioxide tension. Transfusion of whole blood led to a gradual normalisation of the haematological parameters, also accompanied by the normalisation of gasometric indicators (decrease in pCO2 and pO2 and pH increase. Monitoring of selected haematological and gasometric parameters allows to evaluate the efficacy of blood transfusion during treatment of haemolytic disease of foals.

    Full Text Available Convolvulus L., the second largest genus of the family Convolvulaceae, has about 250 species distributed mainly in the temperate and tropical regions of the world, with a cosmopolitan distribution. According to recent studies, this genus is represented in Turkey by 33 species, 9 of which are endemic. Convolvulus species are extensively used in traditional medicine for various purposes as in ulcer treatment, diabetes, and tension. The aim of this study was to investigate the antioxidant activity and the effects of Convolvulus aucheri extract on biochemical indices in rats.The antioxidant activities of various solvent extracts (methanol, ethanol, acetone and benzene obtained from C. aucheri were evaluated by using 2,2-diphenyl-1-picrylhydrazyl (DPPH and β-carotene-linoleic acid assays. In addition, total phenolic contents in all the extracts of C. aucheri were determined as gallic acid equivalents. As for the biochemical assay, the extracts of the plant at the concentrations of 0.5 and 1 ml/100 g body weight/day were administered orally to the experimental groups for 36 days. Blood samples were taken by cardiac venipuncture on the 2nd and 4th weeks after the initial treatment. Aspartate aminotransferase (AST, alanine aminotransferase (ALT, gamma-glutamyltransferase (GGT and blood urea nitrogen (BUN were measured for the determination of liver function.Among all the extracts, the ethanolic extracts of C. aucheri showed the highest antioxidant activity (66.88 ± 0.8%. The highest free radical scavenging activity (59.50 ± 1.2% was recorded on the ethanolic extracts. The phenolic contents of the ethanolic extracts are higher than the other types of extracts (23.03 mg/g GAE. In biochemical assay, it was found a significant increase in the levels of serum ALT, AST and decrease the serum GGT levels in the experimental groups when compared to the controls (p<0.05. On the other hand, we found significant increase in the level of BUN.

    2014-01-01

    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.

    Full Text Available OBJECTIVE: To assess hematological and biochemical features of splenic effluent blood and their influence on the rise of hematological values after splenectomy. METHODS: we studied 20 patients undergoing surgical treatment for schistosomatic portal hypertension. We collected blood samples for CBC, coagulation, bilirubin and albumin in the splenic vein (perioperative and peripheral blood (immediately pre and postoperative periods. RESULTS: the splenic blood showed higher values of red blood cells, hemoglobin, hematocrit, platelet count, total leukocytes, neutrophils, lymphocytes, monocytes, eosinophils and basophils, as well as reduction of laboratory coagulation parameters in relation to peripheral blood collected preoperatively. In the postoperative peripheral blood there was an increase in the overall leukocytes and in their neutrophil component, and decreased levels of basophils, eosinophils and lymphocytes. The other postoperative variables of complete blood count and coagulation tests were not different compared with the splenic blood. The albumin values were lower postoperatively when compared to preoperative and splenic blood. There were higher values of direct bilirubin in the postoperative period when compared with the preoperative and splenic blood. Postoperative indirect bilirubin was lower compared to its value in the splenic blood. CONCLUSION: hematological and biochemical values of splenic effluent blood are higher than those found in peripheral blood in the presence of schistosomal splenomegaly. However, the splenic blood effluent is not sufficient to raise the blood levels found after splenectomy.

    Individuals donating whole blood 13 times in a 2-year period without development of iron deficiency anemia (superdonors) are a self-selected population that is deferred for low hematocrit (Hct) level less frequently than other donors. Iron metabolism was assessed in 138 superdonors through a questionnaire and measurement of Hct, serum ferritin, serum hepcidin, and serum growth differentiation factor 15 (GDF15). Genetic testing for HFE and JAK-2 mutations was also performed. Iron deficiency (ferritin level, <30 microg/L) is present in more than 60 percent of superdonors. Behaviors altering iron status included casual use of iron supplements in males, but not in females, and cigarette smoking that produced increased Hct associated with decreased ferritin. The striking biochemical characteristic of superdonors is greatly decreased serum hepcidin, consistent with their need to absorb maximal amounts of dietary iron to replace that lost from blood donation. GDF15 is normal in most superdonors, indicating that GDF15 overexpression arising from the expanded erythroid pool necessary to replace donated red cells is not the biochemical mechanism for the decreased serum hepcidin. Mutations in JAK-2 were not found, indicating that undiagnosed polycythemia vera is not a common cause for successful repeated blood donation by superdonors. Mutations in HFE associated with hemochromatosis were present in superdonors at the same frequency as the normal population. However, superdonors heterozygous for the H63D mutation in HFE had significantly decreased hepcidin : ferritin ratios demonstrating for the first time that the heterozygous state for HFE mutations is associated with alterations in hepcidin expression.

    Chronic gastritis is a prevalent gastroentestinal disease in Korea. The purpose of this study was to investigate status of foods and nutrients intake and health related biochemical indicators in the patients with chronic gastritis. Daily food and nutrient intake, blood lipids, and antioxidant indicators in the urine, were compared between a group of 19 patients diagnosed with chronic gastritis and a control group of 27 subjects having normal gastroscopy. No significant differences were found in age, height, weight, body mass index, and blood pressure between the two groups. Daily energy intakes were 1900.6 kcal for the chronic gastritis patient group, and 1931.8 kcal for the normal control group without significant difference. No significant difference was found between the two groups in all nutrient intakes except for cholesterol. The chronic gastritis patients consumed lower amount of sugars and sweeteners but greater amount of starchy food groups such as potatoes and legumes than subjects of control group consumed. Also the chronic gastritis patients showed higher serum triglyceride concentration than the normal subjects. These results indicate that the dietary pattern of chronic gastritis patients may have relation to a change in the serum lipid level; however, more systematic research with a larger samples size is required.

A total of 40 clinically healthy male and female Wistar rats were randomly divided into four groups. In the control group (C rats were fed a standard complete diet; in the experimental groups standard diets were supplemented with different doses of bee pollen. Treatment group T1 was given standard diet with the addition of bee pollen at a 0.3% concentration; in group T2 the addition was 0.5%; and in group T3 it was 0.75%. The experimental period lasted for 90 days. A significant effect (P < 0.05 of bee pollen on the body weight gain and feed conversion ratio of female rats was found. Significantly (P < 0.05 higher cholesterol concentration in blood serum of male rats was found in the groups with bee pollen addition (groups T2 and T3 compared to the control group. Lower triglyceride serum content in all female experimental groups (T1 and T3 was observed in comparison to the control. Higher serum cholesterol content in the experimental female rats was detected; significant differences were analysed in groups T1 and T3 compared to the control female group. Rapeseed bee pollen at concentrations of 0.5 and 0.75% positively affected the body weight gain of female rats, however, with higher feed consumption (P < 0.05. Rapeseed bee pollen reduced the triglycerides serum content in female rats and increased the cholesterol serum content in male and female rats (P < 0.05.

    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.

    The economic consequences from mortality of sheep after blood loss can be considerable. To date there are no reports addressing hematologic, blood gas, and biochemical changes in ovine blood stored in CPDA-1 bags. The aim of this study was to investigate hematologic, blood gas, and biochemical alterations resulting from storage of ovine blood in CPDA-1 bags to establish transfusion protocols in sheep. From each of 7 healthy 8-month-old sheep 450 mL of blood were collected into CPDA-1 bags and stored for 35 days in at 3-6°C. Samples were taken from the bags at days 0, 7, 14, 21, and 35. Whole blood was used to assess PCV, MCV, RBC count, pH, pO2 , pCO2 , and concentrations of bicarbonate, sodium, and lactate. Plasma was used to measure potassium, hemoglobin, and glucose concentrations. The PCV remained stable throughout the storage period, while plasma hemoglobin and MCV began to increase on days 7 and 21, respectively. The RBC count began to decrease on day 21. Blood pH decreased and pCO2 increased steadily throughout the storage period. Potassium concentration increased from 3.8 to 18.3 mmol/L on day 7 and remained high thereafter. In contrast, sodium concentration began to decrease on day 7. The results show that ovine blood undergoes hematologic, blood gas, and biochemical changes during storage. Further studies are required to establish RBC viability in CPDA-1 bags after a storage period of 35 days. © 2012 American Society for Veterinary Clinical Pathology.

    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 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.

    In order to study the effect of electromagnetic fields (0.3 mT, 50 Hz) on some biomechanical and biochemical properties of rats’ blood, healthy thirty male albino rats of 150 ± 10 g were divided into three equal groups namely A, B1, B2. Group A used as a control group, group B1 was continuously exposed to a magnetic field of (0.3 mT, 50 Hz) for a period of 21 days for direct effect studies. Group B2 was continuously exposed to the same magnetic field for the same period of time, then was housed away from the magnetic field for a period of 45 days for delayed effects studies. After examination, the results indicated that the apparent viscosity and the consistency index increased significantly and very high significantly for groub B1 and B2 compared to control at Pbone marrow functions. These results are supported by the blood film image, where irregularities and deformations in the RBCs membranes had been occurred. We conclude that the cell membrane properties are highly affected by the extremely low frequency (ELF) magnetic fields, which proved to be biologically toxic.

  18. Biochemical Indicators of Radiation Injury in Man. Proceedings of a Scientific Meeting

    1971-01-01

    After an organism has suffered a radiation insult, knowledge of the dose and localization of the exposure is of the greatest importance for the treatment of any radiation damage. Supplementary to the information obtained from physical dosimetry, data obtained by biochemical indicators can, on the basis of metabolic changes in the irradiated organism, help in making early diagnosis, in assessing the extent of the radiation injury, and making a prognosis. Biochemical tests under optimal conditions would not depend on the quality and distribution of the dose in the body and would also reflect the sensitivity of the individual organisms. The International Atomic Energy Agency and the World Health Organization convened a joint scientific meeting on Biochemical Indicators of Radiation Injury in Man in Paris-Le Vésinet, France, from 22 to 26 June 1970. The main purpose of the meeting was to discuss recent problems in determining which biochemical and metabolic changes occurring in irradiated organisms could be used as indicators of radiation injury and its extent, and could thus be of help in planning the proper treatment of the injured persons. During the meeting the results obtained with various biochemical indicators, and experimental techniques and laboratory methods used in this field, were evaluated and compared. Both research workers and clinicians were invited to participate at the meeting. They discussed the possible value of several tests, used successfully in experimental animals, for clinical application; ways of standardizing suitable tests; and mutual collaboration between laboratories and clinics. The outcome of their discussions is summarized in the conclusions and recommendations which are included in these Proceedings together with the papers presented

    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.

    To investigate the effects of 2 different ways of storage bag placement on some biochemical indexes of leukodepleted red blood cells (LD-RBC) to as to ensure the efficacy and safety of clinical blood transfusion. The whole blood samples of 20 donors (400 ml/donor) were selected for preparating the LP-RBC, which were divided evenly into 10 bags. The 10 bags were randomly divided into 2 groups; the bags in 1 group were placed uprightly, while the bags in another group were placed horizontally. The bags of 2 groups were stored in the same conditions. One storage bag from each group was taken randomly on day 7, 14, 21, 28, 35 respectively, and then the biochemical indexes of samples were detected and analyzed. The values of K(+) and LAC on day 14, the value of LDH on day 28 in the uprightly placed group were higher than those in the horizontally placed group (P value of Na(+) on day 28, and the value of Glu on day 35 in the uprightly placed group were lower than those in horizontally placed group (P 0.05). The storage bags placed by different ways during the storage show different influence on some biochemical indexes of LD-RBC in the storage period.

    Five sheep with average live weight of 38 kg were selected and fitted with permanent ruminal fistulae for the study of the influence of DCAB and cellulase on blood biochemical indexes in sheep. With the design of 5 x 5 Latin square, the goats were undergone four groups of treatments. As sheep in control group were only fed with basic feed, other treatments were fed with basic feed and additives. Those additives were: treatment 1 with cellulase (0.2% of dietary), treatment 2 with DCAB1 (20 mEq/100g DM), treatment 3 with cellulase (0.2% of dietary) and DCAB1 (20 mEq/100g DM) and treatment 4 with cellulase (0.2% of dietary) and DCAB2 (40 mEq/100 g DM). The results show that different DCAB and cellulase had no apparent influence on the concentrations of T 3 and T 4 (P>0.05), but they had significant influence on the concentration of insulin (P 0.05). The study indicated that addition of 0.2% cellulase to dietary while adjusting DCAB to 0.2-40 mEq/100 g DM respectively did not destroy tissues and organs of sheep. (authors)

    The loggerhead turtle (Caretta caretta) is an endangered marine reptile for whom assessing population health requires knowledge of demographic parameters such as individual growth rate. In Cape Verde, as within several populations, adult female loggerhead sea turtles show a size-related behavioral and trophic dichotomy. While smaller females are associated with oceanic habitats, larger females tend to feed in neritic habitats, which is reflected in their physiological condition and in their offspring. The ratio of RNA/DNA provides a measure of cellular protein synthesis capacity, which varies depending on changes in environmental conditions such as temperature and food availability. The purpose of this study was to evaluate the combined use of morphometric data and biochemical indices as predictors of the physiological condition of the females of distinct sizes and hatchlings during their nesting season and how temperature may influence the physiological condition on the offspring. Here we employed biochemical indices based on nucleic acid derived indices (standardized RNA/DNA ratio-sRD, RNA concentration and DNA concentration) in skin tissue as a potential predictor of recent growth rate in nesting females and hatchling loggerhead turtles. Our major findings were that the physiological condition of all nesting females (sRD) decreased during the nesting season, but that females associated with neritic habitats had a higher physiological condition than females associated with oceanic habitats. In addition, the amount of time required for a hatchling to right itself was negatively correlated with its physiological condition (sRD) and shaded nests produced hatchlings with lower sRD. Overall, our results showed that nucleic acid concentrations and ratios of RNA to DNA are an important tool as potential biomarkers of recent growth in marine turtles. Hence, as biochemical indices of instantaneous growth are likely temperature-, size- and age-dependent, the utility and

    The pre-analytical stability of 7 biochemical parameters (parathyroid hormone -PTH-, vitamins A, C E and D, 1,25-dihydroxyvitamin D and insulin) at +4 °C, was studied on whole blood samples before centrifugation. The impact of freezing at -20°C was also analyzed/performed for PTH and vitamin D. The differences in the results of assays for whole blood samples, being kept for different times between sampling time and analysis, from 9 healthy adults, were compaired by using a Student t test. The 7 analytes investigated remained stable up to 4 hours at +4°C in whole blood. This study showed that it is possible to accept uncentrifuged whole blood specimens kept at +4°C before analysis. PTH is affected by freezing whereas vitamin D is not.

    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.

    37 patients with chronic hepatitis B and C were examined. Patients were divided into 3 groups depending on the degree of connective tissue dysplasia. We investigated: free and protein-bounded hydroxyproline, collagenase activity, total alkaline phosphatase and its bone fraction, creatinine, calcium and phosphorus content in the blood serum and urine. It has been found the dependence of collagen synthesis from the state of connective tissue. The higher is the degree of dysplasia, the more intensive is the process of collagen synthesis (P < 0.05). The index of corellation between protein-bounded and free fraction can be used as a biochemical marker for determination the stage of pathological process in the liver and for monitoring the effectiveness of therapy.

    Recent studies have demonstrated associations between ABO blood groups and prognosis in various types of cancers. The aim of this study was to investigate the association between ABO blood groups and biochemical recurrence (BCR) after radical prostatectomy (RP). A total of 555 patients with prostate cancer who underwent RP were included in the study. No patients received neoadjuvant and/or adjuvant therapy. The effect of ABO blood groups on BCR was examined using univariate and multivariate analyses. During the follow-up period (mean, 52.0 months), 166 patients (29.9%) experienced BCR, with a 5-year BCR-free rate of 67.3%. Although the ABO blood group was not a significantly associated with BCR in the univariate analysis, it was an independent predictor of BCR in the multivariate analysis: blood type O patients had a significantly lower risk of BCR compared to type A patients (Hazard ratio, 0.608; 95% confidence interval, 0.410-0.902; P = 0.014). Further analyses revealed that surgical margin status confounded the assessment of the association between the ABO blood group and BCR. In the analyses of patients with a negative surgical margin, the 5-year BCR-free rate in blood type O patients was a significantly higher than that in type A patients (91.2% vs. 71.0%; P = 0.026). Blood type O is significantly associated with a decreased risk of biochemical recurrence after radical prostatectomy. Further studies are needed to clarify the nature of this association.

    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.

    Full Text Available This project was designed to study some biochemical constituents of ovarian follicular fluid (FF and peripheral blood in buffaloes. For this purpose, ovaries were collected from adult buffaloes immediately after slaughter, FF was aspirated and stored at -4°C. Blood samples were also collected from these buffaloes before slaughter, plasma was separated and stored for further analysis. Samples were classified into two groups according to the follicle diameter i.e. small (3-10 mm and large (11-20 mm. The FF and plasma samples were analyzed for various biochemical constituents, including glucose, cholesterol, total proteins, albumin, globulin, sodium, potassium, calcium, magnesium, zinc, triiodothyronine and thyroxine contents, using commercial kits.The results showed that small follicles had significantly lower (P<0.05 glucose contents than large follicles, while blood plasma had significantly higher (P<0.05 glucose contents than fluid from both classes of follicles. The differences in concentrations of cholesterol, total proteins, albumin and globulin between small and large follicles were non-significant. The concentrations of these compounds were higher in the blood than in FF, except albumin, which was higher in FF than in the blood. Contents of electrolytes and trace elements did not vary between the two follicle classes. However, the plasma levels of these electrolytes and trace elements, except potassium and zinc, were significantly higher (p<0.05 than their levels in FF. The level of potassium was significantly higher (P<0.05 in FF than in the plasma, while serum zinc level did not differ from FF. The differences in concentrations of triiodothyronine and thyroxine in fluid from small and large sized follicles were non-significant. Likewise, the levels of these hormones were non-significantly higher in blood plasma than in FF. It was concluded that FF levels of glucose differed between small and large follicle groups, while blood levels of

    The limited availability of animal manure and the high cost of good quality compost lead to difficult soil quality management under organic agriculture. Therefore, it is important to find out alternative organic soil amendments and more flexible strategies that are able to sustain crop productivity and maintain and enhance soil quality. A three years study was carried out in the experimental fields of the Mediterranean Agronomic Institute of Bari located in Valenzano, Italy. The main objective of this research is to investigate the effects of different fertility management strategies on soil quality in order to estimate the role of innovative matrices for their use in organic farming. The experiment consists of seven treatments applied to a common crop rotation. The treatments include alternative organic amendments (1- olive mill wastewater OMW, 2- residues of mushroom cultivation MUS, 3- coffee chaff COF), common soil amendments (4- compost COM, 5- faba bean intercropping LEG, 6- cow manure - MAN) and as a reference treatment (7- mineral fertilizer COV). The soil quality was assessed before and after the application of the treatments, through biological (microbial biomass carbon and nitrogen, soil respiration and metabolic quotient), biochemical (soil enzymatic activities: β-glucosidase, alkaline phospatase, urease, fluorescein diacetate (FDA) hydrolysis), and chemical (pH, soil organic carbon, soil organic matter, total nitrogen, available phosphorous, exchangeable potassium, dissolved organic carbon and total dissolved nitrogen) indicators. Based on the results obtained after the second year, all treatments were able to improve various soil chemical parameters as compared to mineral fertilizer. The incorporation of COF and OMW seemed to be more effective in improving soil total N and exchangeable K, while MAN significantly increased available P. All the amendments enhance dissolved organic C, soil respiration, microbial biomass and metabolic quotient as

    The intensive agricultural managements, increased in the last twenty years, have resulted in a decrease in fertility of soils, representing a serious threat to agricultural productivity due to both the increase in production cost, mainly for intensive use of mineral fertilizers, and the loss of the quality of crops themselves. Organic matter content is closely related to the soil fertility and its progressive reduction in cultivates soils, without a satisfactory recovery, could make agriculture untenable, resulting in a high detrimental effect on environment. But an appropriate soil management practices can improve soil quality by utilizing organic amendments as alternative to mineral fertilizers to increase soil quality and plant growth. In this context, demand of suitable indicators, whose are able to assess the impact of different agricultural managements on soil quality, has increased. It has shown that soil biological and biochemical properties are able to respond to small changes in soil conditions, thus providing information on subtle alterations in soil quality. Aim of this study was to evaluate the use of soil biological and biochemical properties as fertility indicators in agricultural soils under different agricultural managements, sited in Campania Region (Southern Italy). After a preliminary monitoring phase of soil fertility on different farms sited in five agricultural areas of Campania Region, we have selected two farms in two different study areas to assess the effect on soil quality of different organic amendments. In particular, a compost from municipal solid waste and wood from scraps of poplars pruning were supplied in different doses and ratios. Soil samplings after one month from the amendment addition and then every 4 months until a year were carried out. All collected soil samples were characterized by main physical, chemical, biochemical and biological properties. In general, the use of different organic amendments showed a positive effect

    Full Text Available The aim of this work was to monitor the relations between selected indicators of technological properties of milk and blood biochemical parameters of dairy cows with metabolic disorders. Thirty-two cows were chosen, which were divided into 3 groups: first group - cows with metabolic problems of acidosis, second group - cows with metabolic problems of alkalosis, third group - healthy cows. Blood, urine and milk samples were collected. Urea, total lipids, total proteins, glucose and calcium was determined in the blood serum. Pure acidobasic forms, pH and density of urine were determined. Proteins, lactose, non-fat-solids, somatic cells count, calcium, urea, titratable acidity, fermentability, rennetability and thermostability were determined in samples of milk. Significant negative dependences were observed in the group of cows with metabolic problems of acidosis between urea in blood and in milk (r = -0.694, P <0.05, between calcium in blood and in milk (r = -0.653, P <0, 05, and between calcium in milk and glucose in blood (r = -0.648, P <0.05. In the group of cows with alkalosis, statistically significant correlation between total lipids in blood and fat in milk was found (r = -0.879, P <0.05.

    To investigate the important diagnostic indicators for blood stasis syndrome (BSS) in patients of childbearing age with gynaecological diseases. A partial least squared-discriminant analysis (PLS-DA) were applied to BSS symptoms data of patients with gynaecological diseases, and the diagnostic indicators used by doctors of Korean medicine (DKMs) among BSS patients with gynaecological diseases were also investigated. A total of 103 patients of childbearing age with gynaecological diseases and 40 healthy controls were enrolled. Among the 103 patients, 63 (61.7%) and 40 (38.8%) were diagnosed with BSS and non-BSS, respectively, and BSS patients exhibited a more severe extent of disease. A score plot of PLS-DA showed clearly different patterns among the 3 groups. Based on the variable importance on projection of PLS-DA model, menstrual pains, dark lumps in the menstrual blood, ileocoecal tenderness and resistance, sharp pains, and sublingual varicosities were selected as the top fifive most important indicators. Moreover, more than 75% of DKMs chose dark lumps in menstrual blood, menstrual pain, and dark menstrual blood as the diagnostic indicators of BSS in patients with gynaecological diseases, and more than 49% of them also considered sharp pains, dark red tongue, sublingual varicosities, and tendency to bruise easily as diagnostic indicators of BSS. DKMs focused on menstrual symptoms and certain gynaecological symptoms to diagnose BSS patients of childbearing age with female diseases.

    Full Text Available The aim of this study was to evaluate the influence of toxic cyanobacterial water blooms on blood indices in the Nile tilapia (Oreochromis niloticus. Experimental fish were exposed to natural cyanobacterial water blooms (consisting mainly of Microcystis aeruginosa and M. ichthyoblabe which contained microcystins (total concentration 1187 - 1211 μg g-1 of dry weight and 17.4 - 25.4 μg l-1 of water for 28 days without additional feeding. Control groups of fish were kept in another pond without apparent cyanobacterial bloom formation. Experimental and control rearing ponds had the same water source. After exposure, fish were placed in dechlorinated potable water for the same period. Statistical evaluation of the influence of cyanobacterial water bloom on biochemical indices of experimental fish showed a distinct increase of alkaline phosphatase (p ⪬ 0.05, total bilirubin (p ⪬ 0.001, creatinine (p ⪬ 0.01, lactate (p ⪬ 0.01 and urea (p ⪬ 0.01 when compared to controls. After transfer to the dechlorinated potable water the experimental group showed significantly lower values of phosphorus (p ⪬ 0.001, urea (p ⪬ 0.01 and cholinesterase (p ⪬ 0.05 and higher values of lactate (p ⪬ 0.05 and iron (p ⪬ 0.05 compared to controls. It may be concluded that the exposure of the Nile tilapia to the environment containing cyanobacterial water bloom influenced only some biochemical indices. However, this modulation is to a much lower degree compared to the common carp and silver carp.

    Neurosurgical procedures can be complicated by significant blood losses that have the potential to decrease tissue perfusion to critical brain tissue. Red blood cell transfusion is used in a variety of capacities both inside, and outside, of the operating room to prevent untoward neurologic damage. However, evidence-based guidelines concerning thresholds and indications for transfusion in neurosurgery remain limited. Consequently, transfusion practices in neurosurgical patients are highly variable and based on institutional experiences. Recently, a paradigm shift has occurred in neurocritical intensive care units, whereby restrictive transfusion is increasingly favored over liberal transfusion but the ideal strategy remains in clinical equipoise. The authors of this study perform a systematic review of the literature with the objective of capturing the changing landscape of blood transfusion indications in neurosurgical patients.

    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.

    Full Text Available Background: Lead is the oldest known toxic metal, physiologically and biologically harmful to living creatures. This study aimed to evaluate the lead accumulation in the liver and breast muscles of Japanese quail (Coturnix japonica and to compare concentrations in both sexes and its effect on blood biochemical factors. Methods: Twenty-four young farm Japanese quails (25 day old prepared from local breeders in December 2014 and randomly divided into control and treatment group. Treatment group were exposed to 0.4 mg per kg diet of “Lead Acetate” for 21 days. We studied the effects of lead on survival and blood biochemical factors. The lead accumulation in the liver and breast muscles of Japanese quail was determined using atomic absorption. Results: Exposure to lead caused a significant increase in the activity of enzymes (AST, (ALT, (LDH, glucose, creatinine and uric acid in poultry treated with lead compared with the control group (P<0.05. In addition, significant decrease in the activity of ALP, AChE, total protein, albumin, globulin, and triglycerides was found (P<0.05. The treated group had no significant change in the activity of CPK and cholesterol. Lead accumulation was more in the liver rather than the breast muscle. There was no significant difference between males and females as for concentration of lead in muscle and liver of quail. Conclusion: Quail have capabilities to accumulate lead in their tissues. In addition, it can lead to apparent changes in enzymes and blood biochemical factors, which show adverse effects of heavy metals on the immune and physiological system of birds.

    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.

    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.

    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 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

    Twenty-four Large White × Landrace crossbreed primigravid pigs, aged 7.50 to 8.00 months weighing between 86.15 and 88.24 kg were used to study the effects of feeding graded levels of soya bean meal (SBM) replaced blood meal (BM) diets on serum biochemical profile in gestating pigs. The pigs were randomly allotted to four finisher diets formulated such that BM replaced SBM at 0.0, 50.0, 75.0 and 100.0 %, respectively. The diets were T1 (100.0 % SBM, 0.0 % BM), T2 (50.0 % SBM, 50.0 % BM), T3 (25.0 % SBM, 75.0 % BM) and T4 (0.0 % SBM, 100.0 % BM). Individual animal's daily ration of the test diets was 2.20, 2.00 and 2.50 kg at stages one, two and three of gestation. Blood sampling and analysis for the effects of the test diets on biochemical profile of the experimental animals were carried out prior to conception, at weeks 3, 7 and 11 of gestation, respectively. The result showed no significant (P ≥ 0.05) dietary treatment effects on total protein, albumin, globulin fraction, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, creatinine and urea profile of the pigs fed with BM diets when compared to the control fed with 100.0 % SBM. There was however a significant (P ≤ 0.05) variation in these biochemical indices in all the experimental groups at different stages of gestation.

    Full Text Available 60 children with hemorrhagic vasculitis were examined in order to detect ultrasound and biochemical markers of endothelial dysfunction, depending on the degree of acti­vity and the form. Serum monocyte chemoattractant protein 1 (MCP-1 concentration was determined using enzyme-linked immunoassay, the content of nitric oxide by its stable metabolites — NO2, NO3 and S-nitrosothiol, von Willebrand factor — using aggregometry, intima-media complex thickness of the common carotid artery and endothelium-dependent dilation of the brachial artery were evaluated. Levels of von Willebrand factor and MCP-1 significantly increased, depending on the degree of hemorrhagic vasculitis activity. Statistical data show a significant decrease in the concentration of nitric oxide metabolites in the blood serum of children with mixed form and nephritic syndrome. Intima-media complex thickness of the common carotid artery was increased in children with severe hemorrhagic vasculitis, and in children with a mixed form with renal syndrome. We have detected a pathological reaction of endothelium-dependent dilation of the brachial artery regardless of the degree of activity and the form of hemorrhagic vasculitis, this fact evidences direct involvement of the endothelium in the pathological process.

    The aim of this study was to evaluate a biochemical marker with different elements of a normal blood serum and centrifuged blood serum after a different rotation system. For this technique, we used five fractions of a blood Concentrated Growth Factors system (bCGF) and a particular device for the different rotation program. Blood samples were collected from 10 volunteers aged between 35 and 55 in the Operative Unit of the “Sapienza” University of Rome with only a fraction of different biochemical elements. Through an individual blood phase separator tube of venous blood, active factions of serum and 4 fractions of red buffy coat were taken. The biochemical markers with 14 elements were examined at times: P1-11 minutes, P2-12minutes, P3-15 minutes. Exclusively biological materials which are normally applied in the regeneration techniques for different defects and lesions were used with this technique. After specific rotation programs, a different result was obtained for each cycle: P1, P2, P3. In test tubes obtained by separated blood, we observed a higher concentration of proteins, ions, and other antigens compared to normal blood plasma. Examining the biochemical results of different elements, we observed an increase (P≤0,01). Since each person’s DNA is different, we could not have the same results in 5 fractions of blood concentration, we did, however, find a good increase in only a fraction of proteins, immunoglobulin and different ions. We obtained five fractions after centrifugation, and we had an increase in different biochemical elements compared to normal blood (P≤0,01) which is significant at different times. These biochemical elements were stimulated by different growth factors, which are used by the immune system, and they induced the formation of hard and soft tissues and good regeneration.

    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.

    The present investigation has been undertaken to evaluate the role of Spirulina fusiformis in modifying the mercury-induced biochemical alterations in Swiss albino mice. Animals were divided into four groups: (i) control group - only vehicle (0.9% NaCl/olive oil) was given; (ii) HgCl(2) treated group - 5.0mg/kg b.w. HgCl(2) administered as i.p.; (iii) Spirulina treated group - 800mg/kg b.w. Spirulina extract was administered orally; (iv) combination group -S. fusiformis was administered 10 days before mercuric chloride administration and continued up to 30 days after mercuric chloride administration (5.0mg/kg b.w.). The animals were sacrificed on 1, 3, 7, 15 and 30 days and the activity of serum alkaline and acid phosphatase, serum iron level, serum calcium level, blood lipid peroxidation content and blood glutathione (GSH) level were measured. In the present investigation, mercury intoxication causes significant increase (Pcalcium level, acid phosphatase and lipid peroxidation content and significant decrease in iron level, alkaline phosphatase and glutathione level. Spirulina pre- and post-treatment with mercury prevented or reduces mercury-induced alterations in terms of calcium level, iron level, acid and alkaline phosphatase activity in serum, and lipid peroxidation and GSH level in blood. Thus from the present investigation, it can be concluded that Spirulina pre- and post-treatment with HgCl(2) significantly modulate or modify mercury-induced biochemical alteration in blood of Swiss albino mice.

    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.

    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 Low-level helium neon laser has many applications due to its photobiostimulatory effects. Although the therapeutic effects of low-level laser radiation of different wavelengths and doses are well known, but the exact mechanism of action of the laser radiation on living cells is not yet determined. The present study is designed to evaluate the photobiological effects of 2 mw helium neon laser with wavelength of 632.8 nm on hematologic and biochemical factors of rabbit blood for this purpose, 30 male New Zealand white rabbits with the body weight of 1/5-2 kg were randomly allocated into two groups of control and laser treatment. Animals of both groups were anesthetized and those of laser treatment group were subjected to irradiation with helium neon laser at a                        wavelength of 632.8 nm and output 2 mw for 30 minutes. Finally blood samples were collected from all animals and the biochemical and hematologic factors evaluated. Significant difference (p

    Full Text Available Cigarette smoking causes numerous adverse biochemical changes in plasma and blood leading to ill health effects for which therapeutic approaches are sought. The present study investigates the effect of green tea consumption on confirmed cigarette smokers. Blood samples were collected from 120 selected human male volunteers categorized in to four groups viz., controls, smokers, control volunteers consuming green tea with no habit of smoking and smokers consuming green tea were analysed. Results showed that altered plasma glucose, HbA1c, hemoglobin, hematocrit, total cholesterol, lipoprotein patterns (HDL, LDL, VLDL and lipid peroxidation along with vitamins (vitamin-D, vitamin-B12, vitamin-C and minerals (iron, total iron binding capacity, calcium, sodium, potassium, phosphorous, chloride followed by the activities of alanine aminotransferase (ALT, aspartate aminotransferase (AST, gamma glutamyl transferase (γGT and alkaline phosphatase (ALP. Furthermore, phytochemical analysis of green tea confirmed the presence of phenols, flavonoids and tannins. Antioxidants and free radical scavenging effects of green tea were assessed using 2, 2′-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid (ABTS+ and 2, 2-diphenyl-1-picrylhydrazyl (DPPH+. Results of this study clearly demonstrated that the adverse changes observed in the above biochemical parameters in smokers were reversed upon green tea supplementation which can be attributed to the phytoconstituents present in green tea. In conclusion, both in vivo and in vitro studies revealed that phytocompounds present in green tea are able to scavenge free radicals and by there offers protection against smoking induced biochemical alterations.

    The following biochemical indicators were monitored in the serum of beagles whole-body irradiated with 60 Co at a dose of 3 Gy: aspartate aminotransferase, alanine aminotransferase, alpha amylase, lactate dehydrogenase, alkaline phosphatase, total protein, Na + , K + , total lipids, beta lipoprotein and triglycerides. Antibiotics (Oxymykoin, penicillin, streptomycin) were administered to some of the dogs from day 7 to day 21 after irradiation. Apart from the increase in the lipid level at day 1 after irradiation and the drop in the activity of lactate dehydrogenase between day 1 and 7 no significant changes were observed in the course of the first week. In those dogs who were later lost, a significant increase was found in the activity of alkaline phosphatase and alpha amylase and in total lipids and beta lipoproteins betwen days 7 and 10. This increase was less significant in dogs to whom the radioprotectives cystamine and gammaphos (WR-2721) had been administered prior to irradiation. In dogs who survived after the application of radioprotectives the increase was significantly smaller or nil which demonstrates the favourable effect of the radioprotectives. The administration of antibiotics did not significantly influence the time behaviour of the indicators. From the point of view of early diagnosis of radiation damage, none of the indicators proved satisfactory. (A.K.)

    Full Text Available The aim of the study was to detect DGAT1 K232A polymorphism in 57 dairy cows of the Slovak Spotted breed and its crossbreds, and to assess possible effect of the given polymorphism on selected metabolic indices in blood serum after calving. Using the PCR-RFLP method with improved primers enabling better differentiation of genotypes we identified 45 homozygotes for alanine variant in this locus (AA genotype, 2 homozygotes for lysine variant (KK genotype, and 10 heterozygotes (AK genotype. Genotype frequencies were 0.790 for AA genotype, 0.175 for AK genotype, and only 0.035 for KK genotype. Allele frequencies were counted as 0.877 for A allele and 0.123 for K allele. In both groups of animals (AA and AK genotype increased mean values above the upper reference limit of lactate dehydrogenase, and total bilirubin, and decreased levels below the lower reference limit of triglycerides were detected. In the group of animals with AA genotype we also noticed decreased levels of non-esterified fatty acids. On the other hand, increased serum concentrations of total immunoglobulins were found in animals with AK and KK genotype. This is the first study concerning DGAT1 polymorphism in the Slovak Spotted breed and its association with selected biochemical indicators.

    There are many harmful factors that possess a damaging impact on the body of employees at aluminum production. It leads to the development of bronchial asthma (BA), chronic nonobstructive bronchitis (CNB) and chronic obstructive pulmonary disease (COPD). The pathogenesis of these disorders, as well as sensitizing effect offluorine in the aluminum production is not fully understood. The purpose of this work was to study the characteristics of laboratory indices in patients with occupational diseases of the respiratory system. In workers of aluminum production with the diagnosis of occupational diseases of respiratory system (15 patients with a diagnosis of asthma, 30 CNB cases, 20 COPD patients) we evaluated the content of total protein, total cholesterol, high density lipoprotein cholesterol (HDLC), total calcium, phosphorus, ceruloplasmin, hematological indices and performed emigration of leukocytes braking test (TTEEL). Clinical and biochemical profile ofpersons with occupational asthma was characterized by a low level of total calcium and ceruloplasmin, a high concentration of phosphorus in the blood serum and inhibition of leukocyte emigration in the test with sodium fluoride. For aluminum production CNB workers characteristic active proatherogenic process was pronounced by a decrease in the HDLC level and an increase in atherogenic index; higher hematocrit value and concentration of erythrocytes, and more than 50% of cases of sensitization to the presence of sodium fluoride. COPD cases had occupational lower average concentration of hemoglobin in the erythrocyte, total protein in serum, as well as polymorphic variant response to sodium fluoride in the form of a depression and activation of leucocytes emigration.

    Full Text Available Palm oil is thermally oxidized to increase its palatability and this has been a usual practice in most homes. This study sought to assess the biochemical responses of rats to thermally oxidized palm oil diets. Therefore, Wistar strain albino rats (Rattus norveigicus were fed with fresh palm oil (control and thermally oxidized palm oil (test groups diets and water ad libitum for 30 days. Then, the malondialdehyde (MDA contents and total protein of the plasma and liver were determined. Subsequently, the plasma liver function markers [alanine transaminase (ALT, aspartate transaminase (AST, alkaline phosphatase (ALP, albumin (ALB and total bilirubin (TBIL ] and the lipid profile [triglyceride (TRIG, total cholesterol (T-CHOL, high density lipoprotein (HDL-CHOL and low density lipoprotein (LDL-CHOL ] were assayed. The results of the study revealed that there was a significant decrease (P < 0.05 in the plasma and liver total protein, ALB, TRIG and HDL-CHOL of the test groups when compared with the control. Conversely, there was a significant increase (P < 0.05 in the activities of ALT, AST and ALP, TBIL, T-CHOL, LDL-CHOL and plasma/liver MDA of the test groups when compared with the control. These effects were most pronounced in rats fed with 20 min-thermally oxidized palm oil diet. Hence, consumption of thermally oxidized palm oil diets had deleterious effects on biochemical indices in rats. Therefore, cooking with and/or consumption of palm oil subjected to heat treatment for several long periods of time should be discouraged in our homes as this might have deleterious effects on human health.

    Full Text Available OBJECTIVE: To describe the prevalence of hepatic steatosis and to assess the performance of biochemical, anthropometric and body composition indicators for hepatic steatosis in obese teenagers.METHODS: Cross-sectional study including 79 adolecents aged from ten to 18 years old. Hepatic steatosis was diagnosed by abdominal ultrasound in case of moderate or intense hepatorenal contrast and/or a difference in the histogram ≥7 on the right kidney cortex. The insulin resistance was determined by the Homeostasis Model Assessment-Insulin Resistance (HOMA-IR index for values >3.16. Anthropometric and body composition indicators consisted of body mass index, body fat percentage, abdominal circumference and subcutaneous fat. Fasting glycemia and insulin, lipid profile and hepatic enzymes, such as aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase and alkaline phosphatase, were also evaluated. In order to assess the performance of these indicators in the diagnosis of hepatic steatosis in teenagers, a ROC curve analysis was applied.RESULTS: Hepatic steatosis was found in 20% of the patients and insulin resistance, in 29%. Gamma-glutamyltransferase and HOMA-IR were good indicators for predicting hepatic steatosis, with a cutoff of 1.06 times above the reference value for gamma-glutamyltransferase and 3.28 times for the HOMA-IR. The anthropometric indicators, the body fat percentage, the lipid profile, the glycemia and the aspartate aminotransferase did not present significant associations.CONCLUSIONS: Patients with high gamma-glutamyltransferase level and/or HOMA-IR should be submitted to abdominal ultrasound examination due to the increased chance of having hepatic steatosis.

  13. Biochemical Storage Lesions Occurring in Nonirradiated and Irradiated Red Blood Cells: A Brief Review

    Directory of Open Access Journals (Sweden)

    F. Adams

    2015-01-01

    Full Text Available Red blood cells undergo a series of biochemical fluctuations during 35–42-day storage period at 1°C to 6°C. The sodium/potassium pump is immobilised causing a decrease in intracellular potassium with an increase in cytoplasmic sodium levels, glucose levels decline, and acidosis occurs as a result of low pH levels. The frailty of stored erythrocytes triggers the formation of haemoglobin-containing microparticles and the release of cell-free haemoglobin which may add to transfusion difficulties. Lipid peroxidation, oxidative stress to band 3 structures, and other morphological and structural molecular changes also occur leading to spheroechinocytes and osmotic fragility. These changes that transpire in the red cells during the storage period are referred to as “storage lesions.” It is well documented that gamma irradiation exacerbates storage lesions and the reports of increased potassium levels leading to adverse reactions observed in neonates and infants have been of particular concern. There are, however, remarkably few systematic studies comparing the in vitro storage lesions of irradiated and nonirradiated red cell concentrates and it has been suggested that the impact of storage lesions on leucocyte reduced red blood cell concentrate (RBCC is incomplete. The review examines storage lesions in red blood cells and their adverse effects in reference to blood transfusion.

    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 main objective of the present study was to evaluate the temperature chain of red blood cells (RBC) returned unused blood bags using blood temperature indicator and ascertain the factors like transportation time, type, size of coolant box and number of bags per box. A total of 250 blood bags with the indicator were observed for the temperature changes with other factors like transportation time, type and size of coolant box and number of bags per box. The recordings were performed at several checkpoints located between the blood bank and the wards. Out of the 250 bags, 74 (29.6%) showed colour changes in which 64 (86.3%) were returned unused (RU) blood bags. The transportation time for these 74 bags was 818.3 ± 941.643 min, significantly higher than bags without colour changes, (p=0.02). Interestingly, 71.4% of the colour changes occurred within the ward. The 7 litre coolant box with an average of 1-5 blood bags per box had a statistically significant higher percentage of colour change with 59.2% compared to the 5 litre coolant box (p=0.05). This study showed that the temperature chain of blood bags was often not well maintained. These results could be mainly due to the non-adherence to the standard operating procedure (SOP) of blood transfusion and the usage of non-standardized coolant boxes.

    To investigate the correlation between glucose concentrations in serum, plasma, and whole blood measured by a point-of-care glucometer (POCG) and serum glucose concentration measured by a biochemical analyzer. Prospective clinical study. 96 blood samples from 80 dogs and 90 blood samples from 65 cats. Serum, plasma, and whole blood were obtained from each blood sample. The glucose concentrations in serum, plasma, and whole blood measured by a POCG were compared with the serum glucose concentration measured by a biochemical analyzer by use of the Lin concordance correlation coefficient (ρc) and Bland-Altman plots. For both canine and feline samples, glucose concentrations in serum and plasma measured by the POCG were more strongly correlated with the serum glucose concentration measured by the biochemical analyzer (ρc, 0.98 for both canine serum and plasma; ρc, 0.99 for both feline serum and plasma) than was that in whole blood (ρc, 0.62 for canine samples; ρc, 0.90 for feline samples). The mean difference between the glucose concentrations determined by the biochemical analyzer and the POCG in serum, plasma, and whole blood was 0.4, 0.3, and 31 mg/dL, respectively, for canine samples and 7, 6, and 32 mg/dL, respectively, for feline samples. Results indicated that use of a POCG to measure glucose concentrations in serum or plasma may increase the accuracy and reliability of diagnostic and treatment decisions associated with glucose homeostasis disorders in dogs and cats.

    Dietary supplementation of unsaturated fats in ruminants, if not stabilized, can instigate oxidative stress which can have negative impact on production performance and enhance the susceptibility to various diseases. The current study examined the effect of dietary 80 % canola oil and 20 % palm oil blend (CPOB) on serum fatty acids, antioxidant profile and biochemical indices in goats. Thirty Boer bucks (4-5 months old; initial BW, 20.34 ± 0.77 kg) were randomly assigned to diets containing 0, 4 or 8 % CPOB and fed daily for a period of 90 days. Blood was sampled from the goats on 0, 30, 60 and 90 days of the trial and the serum was analyzed for fatty acids, cholesterol, glucose, total protein, antioxidants and lipid oxidation. Neither diet nor sampling time influenced serum TBARS value, catalase, glutathione peroxidase and superoxide dismutase activities, LDL cholesterol, VLDL cholesterol, triglycerides, glucose and total protein. Goats fed 4 and 8 % CPOB had higher (P oil and palm oil blend could be supplemented in diets without instigating oxidative stress in goats.

    In the investigation of a valuable biochemical indicator in radiotherapy applied in the treatment of cancer patients, plasma hemoglobin, serum haptoglobin, total LDH enzyme and LDH isoenzyme distribution levels were measured. In immunological studies immunoproteins were determined quantitatively by immunodiffusion. Patients were irradiated generally by 2 Gy daily doses and measurements of the above factors were made weekly, during a radiation treatment for 4-6 weeks. In most of the cases examined, increase in hemoglobin and haptoglobin values were observed and the time-dependent curves of the changes showed a characteristic shape. The immunosuppressive effect of irradiation was found to be no universe phenomenon, as in some percentage of the cases an increase in the values of the immunoproteins was observed during radiation treatment, especially in grid-irradiation. Cancer patients treated by different type of radiation sources were compared. The effects of 200 kV X-ray, high-energy X-ray, electron and 60-Co-gamma radiation were evaluated and their effectivity compared. A trial was made to differentiate between type of radiation treatment in radiotherapy of cancer and to find the most promising method. (orig.) [de

    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.

    Full Text Available Time course changes in selected biochemical stress indices (corticosterone, triglycerides, glucose, cholesterol following short-term noise exposure at 100 dB for 28 min were studied in broilers aged 42 days. Corticosterone concentrations were found to increase during the first 10 min of noise exposure and to differ significantly from the control (background sound – 50 dB at Time 10 min and 14 min, then decreased continually and at 28 min returned to the initial prestress value. Triglyceride concentrations increased in broilers exposed to 100 dB noise during the first 12 min with a significant difference from the control at 12 min and 14 min. Glucose concentrations were higher due to 100 dB noise exposure for almost the entire period monitored, with significant differences between 100 dB and control broilers at 6 min and from 10 min to 14 min. Similarly as for the corticosterone concentration, a drop in triglycerides and glucose concentrations was seen approximately from Time 14 min and a return to the pre-stress value at 28 min. The cholesterol concentrations showed various temporal patterns with no significant difference between 100 dB and control broilers in this experiment. The pattern of response found in the study indicates that 100 dB noise represents a stress factor in broilers, however, there is the ability of broilers to adapt to an increased level of noise at this intensity after the first 14 min of exposure. The findings obtained in the study may contribute to expanding detailed knowledge of physiological stress responses to this specific noise stimulus in poultry, and could thereby be used to improve the welfare of broilers in intensive housing systems.

    Grape proanthocyanidins (GPCs) are a family of naturally derived polyphenols that have aroused interest in the poultry industry due to their versatile role in animal health. This study was conducted to investigate the potential benefits and appropriate dosages of GPCs on growth performance, jejunum morphology, plasma antioxidant capacity and the biochemical indices of broiler chicks. A total of 280 newly hatched male Cobb 500 broiler chicks were randomly allocated into four treatments of seven replicates each, and were fed a wheat-soybean meal-type diet with or without (control group), 7.5, 15 or 30 mg/kg of GPCs. Results show that dietary GPCs decrease the feed conversion ratio and average daily gain from day 21 to day 42, increase breast muscle yield by day 42 and improve jejunum morphology between day 21 and day 42. Chicks fed 7.5 and 15 mg/kg of GPCs show increased breast muscle yield and exhibit improved jejunum morphologies than birds in the control group. Dietary GPCs fed at a level of 15 mg/kg markedly increased total superoxide dismutase (T-SOD) activity between day 21 and day 42, whereas a supplement of GPCs at 7.5 mg/kg significantly increased T-SOD activity and decreased lipid peroxidation malondialdehyde content by day 42. A supplement of 30 mg/kg of GPCs has no effect on antioxidant status but adversely affects the blood biochemical indices, as evidenced by increased creatinine content, increased alkaline phosphatase by day 21 and increased alanine aminotransferase by day 42 in plasma. GPC levels caused quadratic effect on growth, jejunum morphology and plasma antioxidant capacity. The predicted optimal GPC levels for best plasma antioxidant capacity at 42 days was 13 to 15 mg/kg, for best feed efficiency during grower phase was 16 mg/kg, for best jejunum morphology at 42 days was 17 mg/kg. In conclusion, GPCs (fed at a level of 13 to 17 mg/kg) have the potential to be a promising feed additive for broiler chicks.

Total 14 warmblood sport horses geldings were used 7 horses in control group, 7 horses in experimental group respectively, Slovak warmblood bred, average body weight 525 plus minus 75 kg and 6 8 plus minus 3 Years. The control group of horses were fed by crimped barley, meadow hay and mineral feed mixture. Feed rations in experimental group were supplemented with a photogenic additive containing a blend of essential oils from origanum, anise and citrus, as well as a prebiotic rich in fructooligosaccharides. Blood serum was collected 3 times during the experiment, in the beginning of the experiment, and every 45 days. The experiment lasted 90 days. After the 45 days of phytoadditive supplementation we found a tendency of lower concentrations of serum triglycerides milimol l and total cholesterol milimol 1 in experimental group of horses P. In serum concentrations of glucose, total proteins and urea we find similar values in all of groups. We analyzed a positive effect of phylogenetic additive on organic matter digestibility of feed ration. In experimental group of horses we found significantly, higher organic matter faecal digestibility coefficient 73 per cent in comparison with control group 68 per cent. We analyzed insignificant effect of a phytoadditive on blood serum concentrations during 90 days of experiment. We found positive effect of phytoadditve supplementation on total faecal digestibility of organic nutrients.

    In recent years, new measures of body adiposity have been introduced: lipid accumulation product (LAP), body adiposity index (BAI) and body shape index (ABSI). These indices have been demonstrated to better associate with cardiovascular disease than other measures of adiposity. The aim of the present study was to evaluate if LAP or BAI better associate with blood viscosity than other measures of adiposity (body mass index, BMI; waist circumference, WC; waist-to-hip ratio, W/HR; waist-to-height ratio, W/HtR). 344 subjects were recruited for the present investigation. Exclusion criteria were: diabetes, elevated triglycerides, smoking and drug use. Blood lipids and glucose were measured by routine methods. Blood and plasma viscosity were measured by a cone-plate viscometer. Adiposity measures were computed as previously described. In simple correlation analyses, blood viscosity (BV) correlated with BMI, BAI, and LAP in males and with LAP in females. Correlations between plasma viscosity and adiposity indices were weak and not statistically significant. Other variables significantly related with BV were: gender, HDL- and LDL-Cholesterol, and triglycerides (p index is strongly associated to blood viscosity. This result, along with previous evidence, identifies LAP index as a potential cardiovascular risk marker.

    To determine the haematological and biochemical indicators for the early diagnosis of dengue viral infection. Patients presenting with a fever of less than 2 weeks duration, generalized morbiliform rash and bleeding manifestations were included. Clinical history was recorded and patients were placed on fluid and haematological support. Diagnosis was established by Polymerase Chain Reaction (PCR) for dengue virus or detection of dengue virus specific IgM and IgG. One hundred and four patients met the inclusion criteria during the study period. Sixty six patients had clinical and haematological features suggestive of grade I Dengue Hemorrhagic Fever (DHF); 34 patients had grade II DHF and 4 had grade III DHF out of whom 3 progressed to grade IV DHF. All the patients presented with fever followed by generalized morbiliform rash (81.73%), vomiting (79.8%), abdominal pain (65.38%), backache (62.5%), depression (60.6%) and mucosal bleeding manifestations (34.6%). Clinically, conjunctival infection was present in 93 patients (89.4%), hepatomegaly 59 (56.7%), lymphadenopathy in 17 (16.3%), splenomegaly in 13 (12.5%), pleural effusion in 11 (10.5%) and ascites in 8 (7.6%). Common laboratory findings were thrombocytopenia in 100% patients, leucopenia in 55 (52.8%), raised hematocrit in 52 (50%), and elevated aminotransferases, gamma GT in 100 (96%) patients. The overall mortality was 2.88%. In this series clinical history and examination supported by the triad of thrombocytopenia, raised hematocrit and elevated liver enzymes was sufficient for the early diagnosis of dengue hemorrhagic fever without waiting for dengue serology.

    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.

    Full Text Available Background: Trimethoprim is considered as a trimethoxy benzyl pyrimidine, the action mechanism of which is to block the synthesis of tetrahydrifolate. Sulfamethoxazole is an antibacterial drug from the sulfanamide group, this drug prevents from synthesis of dihydrofolic acid. Trimethoprim which is consumed along with sulfonamide controls the metabolic oxidants which in turn increases the anti microbial effect of each drug. In this research the effects of cotrimoxazole on the biochemical blood factors in adults male rats were studied. Materials and Methods: The animals used in the experiment were 50 male wistar rats each weighting 250 grams. The rats were divided into 5 groups of 10 randomly. The control group, the sham group receiving propylene glycol solution. Three experimenal groups received cotrimoxazole of 30, 60 and 120 mg/kg dosage. The drug injected oral for 14 days. After 14 days, blood samples were taken. Biochemical blood factors( FBS, BUN,TG, Cholestrol, Uric acid,Creatinine were measured. The results of this study were analyzed using appropriate statistical programs sach as SPSS and the Tukey, ANOVA and T- test. Results: Statistical analysis of results showed that concentration of creatinine increased significantly in experimental groups receiving 60 and 120 mg/kg dosage in comparison with the sham and control groups. Also, all groups receiving cotrimoxazole showed a significant increase in BUN concentration in comparison with to the control and sham groups. All groups receiving cotrimoxazole showed significant reduce in TG concentration compared with the control and sham groups. The group receiving cotrimoxazole of 120 mg/kg dosage showed a significant increase in cholesterol concentration compared with the control and sham groups. All groups receiving cotrimoxazole showed no significant difference in FBS and uric acid compared with the control and sham groups ( p <0.05. Conclusion: Likely cotrimoxazole increases cholesterol

    An experiment was conducted in a 3 × 3 (Cu × Zn) factorial experiment based on a completely randomized design to evaluate the effects of dietary copper and zinc on apparent mineral retention and serum biochemical indicators in young male mink on a corn-fish meal based diet. Animals were fed basal diets supplemented with Cu from copper sulfate (CuSO4) and Zn from zinc sulfate (ZnSO4). Supplemental Cu levels were 0, 15, and 30 mg/kg copper, respectively, while supplemental Zn levels were 0, 150, and 300 mg/kg, respectively. A metabolism trial of 4 days was conducted during the last week of experimental feeding. Blood samples were collected via the toe clip to determine blood hematology and blood metabolites. Copper excretion, retention, and digestibility were influenced by dietary copper (P < 0.05), however, there was also a zinc-copper interaction. Copper digestibility and retention were substantially reduced when zinc was added to the low copper diet but showed little change with zinc supplementation of the high copper diet. Both plasma Cu and plasma Zn were influenced by dietary level of the respective mineral (P < 0.05). There was no influence of dietary copper on plasma zinc; however, high Zn in the diet reduced plasma Cu concentrations. There was a zinc-copper interaction for plasma Cu (P = 0.053). Cu-Zn superoxide dismutase (Cu-Zn SOD) activity tended to be influenced by dietary zinc (P = 0.065) and dietary copper (P = 0.035). Dietary copper had a significant effect on ceruloplasmin (CER) and triglyceride (TG) concentrations (P < 0.05). Our results show that moderately high Zn in the diet (Zn:Cu ratio of 40:1) significantly reduce the apparent Cu digestibility. Our results also show that moderately high Cu in the diet increases Cu retention, but not reduces Zn absorption, and moderately high Zn in the diet reduced plasma Cu concentrations and CER activity.

    Full Text Available This study aimed to investigate the correlation between body condition score (BCS, blood biochemical metabolites, milk yield (MY and quality (Mfat in Montbéliarde cattle (31 cows reared in 5 farms of Algerian semi arid area. The BCS was measured in dry and peak of lactation (6 weeks after calving. Blood samples were taken at the time of body condition (BC measurement for determination of energy (Glucose, cholesterol, triglycerides and B-Hydroxybutyrate, nitrogen (urea and albumin and mineral (calcium metabolites. Milk yield was recorded in the 6th week of lactation (peak. A sample of milk for each cow was used to determinate milk fat, density and acidity. The results showed a significant decrease in postpartum BCS accompanied by an increase in cholesterol and B-Hydroxybutyrate (BHB concentration. The correlation analysis showed that BHB concentration in pre calving was negatively correlated with BCS (r=-0.321; P<0.05 and cholesterol (r=-0.308; P<0.05. In postpartum, BCS was negatively correlated with cholesterol (r=-0.416; P<0.05, urea (r=-0.366; P<0.05 and BHB (r=-0.487; P<0.05. However, the level of milk production decreased significantly with high glucose (r=-0.449; P<0.05 and BHB (r=-0.514; P<0.05. The fat content increased significantly with blood triglycerides (r=0.681; P<0.05 and BHB (r=0.522; P<0.05 concentration, indicating a high mobilization of body reserves used for the synthesis of milk fat. In conclusion, it can be assumed that the rate of BHB seems to be the best indicator of the nutritional status of dairy cows that determines their production level and quality.

    The metabolic mechanisms to circannual changes in body mass of bears have yet to be elucidated. We hypothesized that the Japanese black bear (Ursus thibetanus japonicus) has a metabolic mechanism that efficiently converts carbohydrates into body fat by altering insulin sensitivity during the hyperphagic stage before hibernation. To test this hypothesis, we investigated the changes in blood biochemical values and glucose and insulin responses to intravenous glucose tolerance tests (IVGTT) during the active season (August, early and late November). Four, adult, female bears (5-17 years old) were anesthetized with 6 mg/kg TZ (tiletamine HCl and zolazepam HCl) in combination with 0.1 mg/kg acepromazine maleate. The bears were injected intravenously with glucose (0.5 g/kg of body mass), and blood samples were obtained before, at, and intermittently after glucose injection. The basal triglycerides concentration decreased significantly with increase in body mass from August to November. Basal levels of plasma glucose and serum insulin concentrations were not significantly different among groups. The results of IVGTT demonstrated the increased peripheral insulin sensitivity and glucose tolerance in early November. In contrast, peripheral insulin resistance was indicated by the exaggerated insulin response in late November. Our findings suggest that bears shift their glucose and lipid metabolism from the stage of normal activity to the hyperphagic stage in which they show lipogenic-predominant metabolism and accelerate glucose uptake by increasing the peripheral insulin sensitivity.

    Objective: To determine the frequency of hyperfibrinogenaemia, elevated C-reactive protein, hyperuricaemia and elevated lipoprotein A in a clinic population of patients with type 2 Diabetes mellitus (DM) compared with healthy controls; and determine the interrelationship between fasting plasma glucose levels and indices of long-term glycaemic control (fructosamine and glycosylated haemoglobin) in DM. Study Design: Cross-sectional, analytical study. Place and Duration of Study: The study was conducted at the Lagos State University Teaching Hospital, Ikeja, from April to June 2009. Methodology: A total of 200 patients with type 2 DM and 100 age and gender matched healthy controls were recruited for the study. Glycaemic control was assessed using fasting blood glucose, fructosamine and glycosylated haemoglobin levels. The non-traditional risk factors studied included C-reactive protein (CRP), Lipoprotein a (Lpa), serum uric acid (SUA), microalbuminuria and fibrinogen. Mann-whitney, chi-square and Pearson's correlation tests were used for analysis as applicable. Results: Hyperfibrinoginaemia, elevated CRP, LPa, microalbuminuria and hyperuricaemia were present in 3.5%, 65%, 12%, 6% and 57% respectively in type 2 DM. The mean levels of these CV risk factors were significantly higher in subjects with type 2 DM than that of the control subject. There was a positive and significant correlation between HbA1c and FBS (r=0.46, p=0.0001) and HbA1c and fructosamine (r=0.49, p=0.0001). All studied CVS risk factors were related to indices of glycaemic control which were found to be interrelated. Fasting blood glucose significantly correlated with both HbA1c and fructosamine but HbA1c showed better correlation to FPG than fructosamine (r=0.51 vs. 0.32). Conclusion: Glycosylated haemoglobin and fasting plasma glucose but not fructosamine are significantly associated with microalbuminuria, fibrinogen SUA and CRP in type 2 DM. HbA1c was found to be better than fructosamine in

    Full Text Available Passive transfer of immunity in dairy calves is routinely monitored in North America. This study analyzes such type of biochemistry monitoring in 591 calves (Holstein, Fleckvieh from 19 large farms in the Czech Republic. All calves, aged 1–6 days, were blood sampled once. Serum concentrations of total protein, albumin, zinc sulphate turbidity units and γ-glutamyltransferase activity were analysed by photometry methods. The samples were divided according to concentrations of total protein and zinc sulphate turbidity units, and the age of calves. These groups were compared using nonparametric tests. The samples had good mean values (total protein 63.5 g·l-1, albumin 30.5 g·l-1, zinc sulphate turbidity 11.5 U, γ-glutamyltransferase 10.7 μkat·l-1 but 41% and 54% of calves had low total protein (-1 and zinc sulphate turbidity (P P -1; calves aged 3–6 days had significantly lower activity. It is newly suggested that samples be taken from calves 1–3 days old for γ-glutamyltransferase analysis and traditionally anytime during the first week of life for all other indicators. This first extensive analysis of passive transfer in Central Europe shows that there are widespread deficiencies in the feeding of colostrum to calves.

    Full Text Available Background: The potential role of omega – 3 (ω-3 and omega-6 (ω-6 fatty acids on blood biochemical factors are in interest and controversy. Some experiences showed that omega – 3 (ω-3 and omega-6 (ω-6 fatty acids have a potential effect on triglyceride, LDL-cholesterol, HDL-cholesterol and total cholesterol levels in diabetes mellitus. Methods: Male rats were divided into four groups (one normal group and three diabetic groups. Induction of diabetes was done by streptozotocin [50mg/kg, s.c. (STZ]. In diabetic groups, one group was Control, received STZ alone, and the other diabetic groups were fed with fish oil or corn oil for 8 weeks after 4 weeks of induction of diabetes. Plasma glucose, total cholesterol, triglyceride, LDL- choleserol and HDL-cholesterol were measured at 4 and 8 weeks after intervention. Results: Fish oil and corn oil diets had an inhibitory effect on increased plasma glucose in diabetic rat by 46.8% and 40.7%, respectively. Diabetic rats in the control group demonstrated increased plasma total cholesterol, triglyceride and LDL-cholesterol levels, but plasma total cholesterol, triglyceride and LDL-cholesterol levels were significantly decreased and HDL-cholesterol level was increased by both diets in interventional groups. Conclusion: Corn oil and fish oil supplementation have a role on plasma glucose and lipid profile in diabetic rats. To understand the functional mechanisms of these diets, further studies remain to be accomplished.

    Full Text Available Objective: To evaluate the airway function indicators and blood indicators in children with dust mite allergic rhinitis after sublingual immunotherapy. Methods: A total of 68 children with dust mite allergic rhinitis treated in our hospital from November, 2012 to October, 2015 were selected as the research subjects and randomly divided into observation group 34 cases and control group 34 cases. The control group received clinical routine therapy for allergic rhinitis, the observation group received sublingual immunotherapy, and then differences in basic lung function indicator values, small airway function indicator values and levels of serum inflammatory factors as well as serum ECP, TARC, Eotaxin-2 and VCAM were compared between two groups after treatment. Results: The FVC, FEV1, PEF and FEV1/FVC values of the observation group after treatment were higher than those of the control group (P<0.05; the MMEF, MEF50% and MEF25% values of the observation group were higher than those of the control group, and the proportion of AHR was lower than that of the control group (P<0.05; the serum IL-4, IL-9, IL-12, IL-13 and IL-16 levels of the observation group after treatment were lower than those of the control group, and the IL-10 and IL-12 levels are higher than those of the control group (P<0.05; the serum ECP, TARC, Eotaxin-2 and VCAM levels of the observation group children after treatment were lower than those of the control group (P<0.05. Conclusions: Sublingual immunotherapy for children with dust mite allergic rhinitis can optimize the airway function, reduce the systemic inflammatory response and eventually improve the children’s overall state, and it’s has positive clinical significance.

    Estimation of the neurological prognosis of infants suffering from perinatal asphyxia and signs of hypoxic-ischemic encephalopathy is of great clinical importance; however, it remains difficult to satisfactorily assess these signs with current standard medical practices. Prognoses are typically based on data obtained from clinical examinations and neurological tests, such as electroencephalography (EEG) and neuroimaging, but their sensitivities and specificities are far from optimal, and they do not always reliably predict future neurological sequelae. In an attempt to improve prognostic estimates, neurological research envisaged various biochemical markers detectable in the umbilical cord blood of newborns (NB). Few studies examining these biochemical factors in the whole blood of newborns exist. Thus, the aim of this study was to determine the expression and concentrations of proinflammatory cytokines (TNF-α, IL-1β and IL-6) and specific CNS enzymes (S-100 and enolase) in infants with perinatal asphyxia. These data were compared between the affected infants and controls and were related to the degree of HIE to determine their utilities as biochemical markers for early diagnosis and prognosis. The levels of the proinflammatory cytokines and enzymes were measured by enzyme-linked immunosorbent assay (ELISA) and Reverse Transcription polymerase chain reaction (RT-PCR). The expression and serum levels of the proinflammatory cytokines, enolase and S-100 were significantly increased in the children with asphyxia compared with the controls. The role of cytokines after hypoxic-ischemic insult has been determined in studies of transgenic mice that support the use of these molecules as candidate biomarkers. Similarly, S-100 and enolase are considered promising candidates because these markers have been correlated with tissue damage in different experimental models. Copyright © 2016.

    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.

    This study was conducted to identify dietary patterns and evaluated their association with biochemical blood profiles and body weight among adults with type 2 diabetes mellitus. This was a cross sectional study conducted among 400 patients with type 2 diabetes mellitus in Tehran from March to August 2013. Biochemical blood profiles, socio-demographic, lifestyle, anthropometric measurements, and dietary data were obtained. Dietary data from food frequency questionnaire were used to derive dietary patterns. Factor analysis was conducted to ascertain the dietary patterns, and analysis of covariance was fitted to assess the relation between blood profiles, body weight and adherence to dietary patterns. Three dietary patterns by factor analysis were identified, Vegetable & Poultry, Western and Semi-healthy. After control for potential confounders, body mass index (b = -0/03, p fasting blood glucose (b = 0.014, p related to HDL-cholesterol (b = 0.006 p related to body weight, semi healthy related to lower LDL and higher HDL cholesterol whereas western related to higher fasting blood glucose and total cholesterol. Further studies are necessary to confirm the benefits of the dietary patterns for diabetes.

    In the work authors inform results on studying influence of a productive solution of uranium on some biochemical parameters of blood of an organism at experimental animals. It is established that all samples of a productive solution of uranium possesses high toxicity and causes destruction of experimental animals with infringement of a picture of blood. Experiments on influence on biochemical and hematology defined parameters of blood on chickens - broilers and on which female quails from daily age raised on cellular batteries in communities on 50 heads in conditions adequate to the requirement. Fed in plenty with the dry forages prepared according to 'Recommendations on the normalized feeding an agricultural bird' (1996), recipes 5-2; 6-1. To chickens in plenty allowed water from auto drinking bowls. Conditions of a micro climate corresponded to hygienic requirements. At carrying out of experiences studied the following parameters: preservation of a livestock, the reason of a withdrawal, weight of a body - weekly up to the end of experience, consumption of a forage, an expense of a forage for 1 kg of a gain have established weight of a body the methods standard in poultry farming. After application of a productive solution took blood from under wings of a vein and in blood have established maintenance of hemoglobin, quantity of red cells, leukocytes and a leukocyte of the formula, the maintenance of calcium and phosphorus.

    The study was performed in eight high-pregnant cows in which medium to high ketonuria was repeatedly detected. The control group consisted of six cows free from ketonuria before parturition. Blood and urine were sampled from the cows two to eight weeks before parturition, on the day of parturition, 24 hours, three to five days and two to six weeks after parturition. The concentrations of oxidated ketone bodies and beta-hydroxybutyrate were determined by the distilling method. Further, the values of clinico-biochemical parameters in the urine and blood were determined within the range of the preventive diagnosis system. No marked changes in the health condition were found by the current clinical examination. The average concentration of total ketone bodies in the blood of the cows two to eight weeks before parturition was 29.2 mg per litre; the respective values recorded in the control cows were lower by about a half. The concentration of ketone bodies in the blood of the cows in the experimental group decreased on the day of parturition. The decrease was followed by a gradual rise of the total ketone bodies content in the blood up to 50.6 mg per litre two to six weeks after parturition. Alterations testifying to a disorder in the function of liver were observed in the cows of both groups throughout the period under study. The disorder was due to excessive administration of crude protein to the high-pregnant cows combined with the use of low-quality silage. After parturition the feed ration was not differentiated according to performance and was deficient in the basic nutrients and vitamins. Ketonuria was obviously due to the simultaneous intensification of hepatal and alimentary ketogenesis, caused by hepatopathy in combination with the intake of large amounts of poor-quality silage containing butyric acid.

    Two groups of dogs were fed for 90 days a diet irradiated with 60 Co to a dose of 25 kGy/kg. Two other groups of experimental animals were fed over the same period a nonirradiated diet. Laboratory examinations of the irradiated feeds showed their microbiological and mycological intactness. Irradiation caused a significant 35% degradation of essential amino acids and an increase in ammoniacal nitrogen, destruction changes in the lipid component of the feeds and partial decomposition of the saccharide component. Organoleptic examination of the irradiated feeds did not show any perceptible changes. Hematological examination of the animals fed the irradiated feeds showed significant negative effects on the blood count. Biochemical examination of the blood serum and plasma showed that the total protein of the experimental dogs dropped and that the creatinine level had also significantly decreased. The increase in free ammonia caused by ionizing radiation increased the pH level in the dogs' blood. The destruction of the lipid fraction in the feeds caused a decrease in the activity of lipofilic axerophthol thereby distrubing the biological value of the feeds. There was a significant decrease in the magnesium level in animals fed the irradiated feeds without biological supplements. On the other hand, the levels of potassium, calcium and phosphorus did not reflect the difference between the two groups of animals. (author)

    The freshwater golden apple snail, Pomacea canaliculata, is one of the world's 100 worst invasive alien species. The snails' wide distribution, high abundance, and sensitivity to environmental pollution make them a potential bioindicator for environmental contamination. In this study, the biochemical status of golden apple snails collected from paddy fields throughout the island of Taiwan was examined. This study found that the biochemical status of apple snails collected from paddy fields differed from that of animals bred and maintained in the laboratory. Furthermore, certain biochemical endpoints of the snails collected from the paddy fields before and after agricultural activities were also different-hemolymphatic vitellogenin protein was induced in male snail after exposure to estrogen-like chemicals, the hepatic monooxygenase (1.97 +/- 0.50 deltaA(650mm) 30 min(-1) mg(-1) protein in control group) and glutathione S transferase (0.02 +/- 0.01 delta A(340mm) 30 min(-1) mg(-1) protein in control group) snails exposed to pesticides, as well as the hepatopancreatic levels of aspartate aminotransferase (450.00 +/- 59.40 U mg(-1) mg(-1) protein in control group) and alanine aminotransferase (233.27 +/- 42.09 U mg(-1) mg(-1) protein in control group) decreased the indicating that xenobiotics destroyed hepatopancreatic. The above findings reveal that apple snail could be used as a practical bioindicator to monitor anthropogenic environmental pollution.

    The tolerance potential against the oxidative injury in native plants from forest ecosystems affected by environmental stressors depends on how efficiently they keep their pro-oxidant/antioxidant balance. Great variations in plant tolerance are expected, highlighting the higher relevance of measuring biochemical leaf trait indicators of oxidative injury in species with similar functions in the forest than in single species. The use of this functional approach seems very useful in the Brazilian Atlantic Forest because it still holds high plant diversity and was the focus of this study. We aimed at determining the tolerance potential of tree species from the Atlantic Forest remnants in SE Brazil against multiple oxidative environmental stressors. We assumed that pioneer tree species are more tolerant against oxidative stress than non-pioneer tree species and that their tolerance potential vary spatially in response to distinct combined effects of oxidative environmental stressors. The study was carried out in three Atlantic Forest remnants, which differ in physiognomy, species composition, climatic characteristics and air pollution exposure. Leaves of three pioneer and three non-pioneer species were collected from each forest remnant during wet (January 2015) and dry periods (June 2015), for analyses of non-enzymatic and enzymatic antioxidants and oxidative injury indicators. Both hypotheses were confirmed. The pioneer tree species displayed biochemical leaf traits (e.g. high levels of ascorbic acid, glutathione and carotenoids and lower lipid peroxidation) that indicate their higher potential tolerance against oxidative environmental stressors than non-pioneer species. The biochemical leaf traits of both successional groups of species varied between the forest remnants, in response to a linear combination of oxidative environmental stressors, from natural (relative humidity and temperature) and anthropogenic sources (ozone and nitrogen dioxide).

  19. Architectural and biochemical expressions of mustard gas keratopathy: preclinical indicators and pathogenic mechanisms.

    Directory of Open Access Journals (Sweden)

    Patrick McNutt

    Full Text Available A subset of victims of ocular sulfur mustard (SM exposure develops an irreversible, idiotypic keratitis with associated secondary pathologies, collectively referred to as mustard gas keratopathy (MGK. MGK involves a progressive corneal degeneration resulting in chronic ocular discomfort and impaired vision for which clinical interventions have typically had poor outcomes. Using a rabbit corneal vapor exposure model, we previously demonstrated a clinical progression with acute and chronic sequelae similar to that observed in human casualties. However, a better understanding of the temporal changes that occur during the biphasic SM injury is crucial to mechanistic understanding and therapeutic development. Here we evaluate the histopathologic, biochemical and ultrastructural expressions of pathogenesis of the chronic SM injury over eight weeks. We confirm that MGK onset exhibits a biphasic trajectory involving corneal surface regeneration over the first two weeks, followed by the rapid development and progressive degeneration of corneal structure. Preclinical markers of corneal dysfunction were identified, including destabilization of the basal corneal epithelium, basement membrane zone abnormalities and stromal deformation. Clinical sequelae of MGK appeared abruptly three weeks after exposure, and included profound anterior edema, recurring corneal erosions, basement membrane disorganization, basal cell necrosis and stromal degeneration. Unlike resolved corneas, MGK corneas exhibited frustrated corneal wound repair, with significantly elevated histopathology scores. Increased lacrimation, disruption of the basement membrane and accumulation of pro-inflammatory mediators in the aqueous humor provide several mechanisms for corneal degeneration. These data suggest that the chronic injury is fundamentally distinct from the acute lesion, involving injury mechanisms that operate on different time scales and in different corneal tissues.

    Full Text Available Background and Objective: The implementation of quality system and continuous evaluation of all activities of the Blood Transfusion Services (BTS can help to achieve the maximum quantity and quality of safe blood. Optimizing blood collection and processing would reduce the rate of discard and improve the efficiency of the BTS. The objective of this study is to determine the rate of discard of blood and blood component and identify its reasons at the National Blood Centre (NBC, Kuala Lumpur, during the year of 2007 in order to introduce appropriate intervention. Study Designs and Methods: Data on the number of discarded whole blood units and its components, reasons for discard, and the number of blood components processed as well as the number of collected blood units were obtained from the Blood Bank Information System - NBC database. These were analyzed. Results: The total number of blood units collected in 2007 was 171169 from which 390636 units of components were prepared. The total number of discarded whole blood units and its components was 8968 (2.3%. Platelet concentrate recorded the highest of discard at 6% (3909 followed by whole blood at 3.7% (647, fresh frozen plasma (FFP at 2.5% (2839, and cryoprecipitate at 2% (620. The rate of discarded packed red blood cells RBCs, plasma aphaeresis, and PLT aphaeresis was less than 1% at 0.6% (902, 0.6% (37, and 0.29% (14, respectively. RBC contamination of PLT and plasma were the major cause of discard at 40% (3558. Other causes include leakage (26% - 2306, lipemia (25% - 2208, and underweight (4% - 353. Conclusion: Good donor selection, training and evaluation of the staff, as well as implementation of automation will help to improve processes and output of BTS. This would reduce discard of blood components and wastage caused by non conformance.

    Full Text Available Abstract Background Hematologic and biochemical data are needed to characterize the health status of animal populations over time to determine the habitat quality and captivity conditions. Blood components and the chemical entities that they transport change predominantly with sex and age. The aim of this study was to utilize blood chemistry monitoring to establish the reference levels in a small prosimian primate, the Grey Mouse Lemur (Microcebus murinus. Method In the captive colony, mouse lemurs may live 10–12 years, and three age groups for both males and females were studied: young (1–3 years, middle-aged (4–5 years and old (6–10 years. Blood biochemical markers were measured using the VetScan Comprehensive Diagnostic Profile. Because many life history traits of this primate are highly dependent on the photoperiod (body mass and reproduction, the effect of season was also assessed. Results The main effect of age was observed in blood markers of renal functions such as creatinine, which was higher among females. Additionally, blood urea nitrogen significantly increased with age and is potentially linked to chronic renal insufficiency, which has been described in captive mouse lemurs. The results demonstrated significant effects related to season, especially in blood protein levels and glucose rates; these effects were observed regardless of gender or age and were likely due to seasonal variations in food intake, which is very marked in this species. Conclusion These results were highly similar with those obtained in other primate species and can serve as references for future research of the Grey Mouse Lemur.

    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.

    Full Text Available Deoxynivalenol (DON, produced by the Fusarium genus, is a major contaminant of cereal grains used in the production of fish feed. The effect of mycotoxin deoxynivalenol on rainbow trout (Oncorhynchus mykiss was studied using a commercial feed with the addition of DON in a dose of 2 mg/kg feed. The fish (n=40 were exposed to the mycotoxin for 23 days. The trout were divided into two groups, control and experimental groups. Control groups were fed a commercial feed naturally contaminated with a low concentration of DON (225 μg/kg feed; experimental groups were fed a commercial feed with the addition of DON (1964 μg/kg feed. Plasma biochemical and haematological indices, biometric parameters, and histopathological changes were assessed at the end of the experiment. The experimental groups showed significantly lower values in MCH (P<0.05. In biochemical indices, after 23-day exposure, a significant decrease in glucose, cholesterol (P<0.05, and ammonia (P<0.01 was recorded in the experimental group compared to the control group. Our assessment showed no significant changes in biometric parameters. The histopathological examination revealed disorders in the caudal kidney of the exposed fish. The obtained data show the sensitivity of rainbow trout (O. mykiss to deoxynivalenol.

    Cardiopulmonary bypass (CPB), functioning as the pumping system and the gas exchange functions, is one of the important instruments in cardiovascular operations. But it has many unfavourable problems such as massive blood transfusion, hemodilution, abnormality of coagulation, etc. In fact, 5 or 6 units of blood are necessary to prime CPB in infant, child, and adult. After CPB, massive blood transfusion is necessary to keep good circulation, and to recover from hemodilution and abnormal coagul...

    The stability of biochemical analytes has already been investigated, but results strongly differ depending on parameters, methodologies, and sample storage times. We investigated the stability for many biochemical parameters after different storage times of both whole blood and plasma, in order to define acceptable pre- and postcentrifugation delays in hospital laboratories. Twenty-four analytes were measured (Modular® Roche analyzer) in plasma obtained from blood collected into lithium heparin gel tubes, after 2-6 hr of storage at room temperature either before (n = 28: stability in whole blood) or after (n = 21: stability in plasma) centrifugation. Variations in concentrations were expressed as mean bias from baseline, using the analytical change limit (ACL%) or the reference change value (RCV%) as acceptance limit. In tubes stored before centrifugation, mean plasma concentrations significantly decreased after 3 hr for phosphorus (-6.1% [95% CI: -7.4 to -4.7%]; ACL 4.62%) and lactate dehydrogenase (LDH; -5.7% [95% CI: -7.4 to -4.1%]; ACL 5.17%), and slightly decreased after 6 hr for potassium (-2.9% [95% CI: -5.3 to -0.5%]; ACL 4.13%). In plasma stored after centrifugation, mean concentrations decreased after 6 hr for bicarbonates (-19.7% [95% CI: -22.9 to -16.5%]; ACL 15.4%), and moderately increased after 4 hr for LDH (+6.0% [95% CI: +4.3 to +7.6%]; ACL 5.17%). Based on RCV, all the analytes can be considered stable up to 6 hr, whether before or after centrifugation. This study proposes acceptable delays for most biochemical tests on lithium heparin gel tubes arriving at the laboratory or needing to be reanalyzed. © 2016 Wiley Periodicals, Inc.

    To determine blood cell morphologic characteristics and hematologic and plasma biochemical reference ranges for iguanas housed in a warm indoor and outdoor environment with regular exposure to direct sunlight. Original study. 51 clinically normal iguanas (18 males, 25 females, and 8 juveniles) housed in 3 Florida locations. Blood was collected from the coccygeal or ventral abdominal vein. Any samples that had obvious hemolysis or clot formation were not used. Leukocyte counts were determined manually; other hematologic values were obtained by use of a commercially available cell counter. Plasma biochemical values were determined by use of a spectrophotometric chemistry analyzer. Blood smears were stained with Wright-Giemsa and cytochemical stains for morphologic and cytochemical evaluation. Hematologic ranges were generally higher in this study than previously reported. Thrombocytes were variable in appearance between individuals and sometimes difficult to distinguish from lymphocytes on a Wright-Giemsa preparation. Concentrations of calcium, phosphorus, total protein, globulins, and cholesterol were significantly higher, and the albumin:globulin ratio was significantly lower, in healthy gravid females than in male or nongravid female iguanas. Nongravid females had significantly higher calcium and cholesterol concentrations, compared with males. The calcium:phosphorus ratio was > 1 in all iguanas. Gravid females had a calcium phosphorus product ranging between 210 and 800. Intracytoplasmic inclusions were identified within the erythrocytes of some iguanas. Hematologic ranges for iguanas in this study are higher than those reported for iguanas. Sex and age of the iguana should be considered when evaluating biochemical values. Healthy ovulating and gravid females may have significantly increased electrolyte and protein concentrations, but maintain a calcium:phosphorus ratio > 1.

Fishes were treated with 0 (control, 0.1, 0.5 and 1% of yarrow extract for 30 days. Plasma alanine aminotransferase (ALT, aspartate aminotransferase (AST, lactate dehydrogenase (LDH, alkaline phosphatase (ALP, creatine kinase (CK, peroxidase activity, total complement and lysozyme activity, glucose, total protein, triglyceride and cholesterol were measured after 15 and 30 days of yarrow treatment. There were no significant changes in the lysozyme activity and glucose levels. Total protein and globulin levels were significantly higher in the fish fed with diets enriched with 1% yarrow extract on day 30. Triglyceride and cholesterol levels was significantly decreased in the fish fed with diets containing 0.5% and 1% yarrow extract on day 30 (P<0.05. LDH, CK and peroxidase activities in the fish fed with diets having 1% yarrow extract were significantly decreased at the end of the experiment (P<0.05. In contrast, a significant increase in AST, ALP and total complement activity was observed in the fish fed with 1% yarrow extract diet, on day 15 (P<0.05. The weight gain and specific growth rate increased and food conversion ratio decreased in in the fish fed 1% yarrow extract on day 30. Condition factor in the fish fed with yarrow extract was significantly higher than control group on 30 day. In conclusion, on the basis of these results, oral administration of yarrow extract up to 0.5% have not side effect on blood biochemical and clinical parameters of fishes. However, oral administration of 1% of yarrow extract caused cytotoxicity and modifications in blood biochemical parameters of fish.

    Full Text Available The aim of the present study was to evaluate the effect of breed on haematological and biochemical indicators in 3 dwarf rabbit breeds. In the experiment, 30 sexually intact dwarf rabbit females aged 6 mo were used. With the sole exception of white blood cells and haematocrit value, breed had the most significant effect on the majority of haematological indicators monitored. The red blood cell count was higher in the Dwarf Lop compared to the Netherland Dwarf (+1.91×1012 cells/L; P<0.05 and also the Teddy Dwarf (+1.32×1012 cells/L; P<0.05. For haemoglobin concentration, a higher value was found in the Netherland Dwarf than in the Teddy Dwarf (+39.29 g/L; P<0.05 and the Dwarf Lop (+26.36 g/L; P<0.05. For erythrocytic indicators, the highest values of mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration were found in the Netherland Dwarf. The breed had a significant effect on the urea and potassium values. A higher value of urea was recorded in the Dwarf Lop compared to the Teddy Dwarf (+1.56 mmol/L; P<0.05. For potassium, a higher value was found in the Netherland Dwarf compared to the Teddy Dwarf (+0.85 mmol/L; P<0.05. In addition, a significantly positive correlation (P<0.05 was found between the live weight of dwarf females and values of haematocrit (0.49, albumin (0.54, alanine aminotransferase (0.51, and aspartate aminotransferase (0.41, while a significantly negative correlation (P<0.05 was found between their live weight and values of triacylglycerols (–0.44, alkaline phosphatase (–0.38 and inorganic phosphorus (–0.52.

    Full Text Available The contents of total phenolic compounds, chlorogenic acid and peroxidase activity as well as monophenols to polyphenols ratio were studies in the suckers of the hops as indices of resistance to Verticillium albo-atrum and Fusarium sambucinum. The suckers of hop taken in the early spring from the healthy and infected plots were used in the experiments. As a research material were included cv. 'Northern Brewer' - a wilt tolerant variety, two wild susceptible varieties - cv. 'Lubelski' and cv. 'Brewers Gold', four breeding clones and one male plant. It was found that, 'Northern Brewer' contains more total phenolic compounds, rnonophenols and chlorogenic acid, and in particular considerably higher peroxidase activity as compared to cv. 'Lubelski'. Taking into consideration the contents of these compounds, in the majority of cases, the new breeding clones were similar to the mother variety 'Northern Brewer'. It seems resonable to assume, that the new clones should be more wilt tolerant than varieties and populations cultivated in our country.

    The main objectives of this study were (1) to gain insight into sensitivities of vital organs systems after treatments with cadmium chloride (CdCl 2 ), gamma ( 60 Co) radiation, and combined CdCl 2 -gamma radiation; (2) to determine physiological and cellular/molecular changes after these same treatments; and (3) to develop a summary of biochemical/hematological indicators for each insult individually, as well as for the co-insult treatment. Three lethality studies, Acute CdCl 2 , Chronic CdCl 2 , and Acute Radiation, wwere used to determine sublethal doses for the fourth study (Co-insult), which utilized various combinations of CdCl 2 and gamma radiation and from which the hematological and biochemical data were derived. Radiation groups exhibited statistically significant decreases in the total number of leukocytes, lymphocytes, and polyneutrophils. Significant increases were seen in serum iron, lactate dehydrogenase (LDH), alkaline phosphatase, and triglycerides. Cadmium groups had increased total numbers of leukocytes, polyneutrophils, and serum glutamic oxaloacetate transminase (SGOT). Decreases were seen in lymphocytes, hemoglobin, hematocrit, total red blood cell counts, and total protein. When co-insult treatments were used, significant decreases were seen in the total number of leukocytes, polyneutrophils, lymphocytes, hemoglobin, total red blood cells, and serum iron

    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)

    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.

    Thiamine (vitamin B1) is an essential enzyme cofactor in most organisms required at several stages of anabolic and catabolic intermediary metabolism. However, little is known on the positive effects of thiamine in diabetic type 1 (DMT1) patients. The objectives of this study were to evaluate the biochemical changes related to thiamine deficiency in patients with DMT1 outcomes among Saudi adults. We hypothesized that blood thiamine deficiency in patients with DMT1 manifestations might lead to an increase in metabolic syndrome. A total of 77 patients with DMT1 (age 35.8 ± 5.5) and 81 controls (age 45.0 ± 18.1) (total N = 158) were randomly selected from the Riyadh Cohort Study for inclusion. Saudi adults with diabetes type 1, a significant decrease in systolic (P blood pressure (P = 0.008) and microalbuminuria (P = 0.02). Moreover, cholesterol, glucose and triglycerides were significantly increased (P 0.001, 0.001 and 0.008, respectively) in patients with diabetes type 1 compared to controls. On the other hand, HDL, TMP, TDP and thiamine, were significantly decreased in patients with diabetes type 1 (P 0.005, 0.002, 0.005, and 0.002), respectively. A strong association between blood thiamine level and diabetes type 1 was detected in our study population. The results confirmed the role of thiamine and thiamine phosphate esters, in preventing metabolic changes and complications of diabetes type 1. The levels of these thiamine and thiamine phosphate esters were correlated with diabetes related biomarkers including HDL, glucose, triglycerides and cholesterol, as well as microalbuminuria, LDL and urine thiamine. The results support a pivotal role of blood thiamine and its phosphate esters in preventing the biochemical changes and complications in patients with DMT1.

Paraquat can have adverse effects on the health of aquatic organisms. The aim of this study was to detect the alterations in the blood biochemical parameters of common carp exposed to sub-lethal concentrations of commercial formulations of paraquat. Methods: The fish were exposed to sub-lethal concentrations (0.2 and 0.4 mg.L-1 of paraquat for 21 days. Biochemical parameters including glucose, total protein, albumin, globulin, creatinine, triglyceride and cholesterol levels, and aspartate aminotransferase (AST, alanine aminotransferase (ALT, lactate dehydrogenase (LDH, creatine phosphokinase (CK, alkaline phosphatase (ALP and γ-glutamyl transferase (GGT activities were measured. Results: A significantly increase was observed in AST activity in fish exposed to 0.4 mg.L-1 paraquat. Paraquat caused a significant (P < 0.05 increase in plasma ALT, LDH and CPK activities and plasma creatinine levels. Although ALP activity significantly (P < 0.05 increased in fish exposed to 0.2 mg.L-1 paraquat, the fish exposed to 0.4mg.L-1 paraquat exhibited a significant (P < 0.05 decrease in ALP activity. A significant (P < 0.05 decrease in GGT activity, total protein, albumin and globulin levels as well as cholesterol and triglyceride levels was observed in fish exposed to sub-lethal concentrations of paraquat. Conclusion: Exposure to sub-lethal concentrations of paraquat may cause changes in blood biochemical parameters in common carp.

    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.

    The aim of the study is to examine the relationship between toner-exposed work and health indices related to respiratory disorders and to confirm the baseline of a cohort study to clarify the effect of toner exposure in manufacturing plants. Subjects were 1614 male workers (809 toner-exposed workers and 805 referents) who were engaged in toner manufacturing plants in Japan (Fuji Xerox Co., Ltd). The age of subjects was from 19 to 59 years, and the average age was 40.2 years(median 40 years, SD 7.67). We conducted a pulmonary function test (PEFR, VC, FVC, FEV(1.0)%, V25/Ht) and a blood cell test (RBC, Hb, Hct, Plt, WBC, cell contents of WBC) and measured biochemical indices in blood (ALT, AST, gamma-GTP, CRP, IgE) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) in urine. Student t-test and logistic regression analysis were applied to compare between the toner-exposed workers and the referents and to analyze the relationship among indices of effects and independent factors. There was no significant difference between the two groups in blood cell count and biochemical indices. Inflammation- and allergy-related markers such as 8OHdG and IgE also showed no significant difference between toner-exposed workers and the referents. The influence of smoking on pulmonary function indices was observed, but there was no relationship between the pulmonary function and toner-exposed work. In this article, we report a preliminary cross-sectional analysis in the subjects of a cohort study. No difference in pulmonary function indices was observed between the toner-exposed workers and the referents, and there was no consistent relationship between the exposure status and examined indices; however, the prevalence of subjective respiratory symptoms was higher in the exposed workers as presented in another report. Further analysis is important in the ongoing cohort study to clarify the effect of toner exposure on respiratory systems.

    The experiment was designed to study the effect of supplemented dried live yeast (DLY) + vitamin E to the diet of growing calves under hot summer conditions in Egypt. Six bovine Baladi calves with 115 kg initial body weight and 8-10 months old were used during two periods. In the first period, the calves were offered the concentrated basal diet only for one month and considered as a control period. In the second period, the calves were fed the same basal diet which supplemented with 15 g dried live yeast (Saccharomyces cerevisiae) + 600 IU vitamin E (alpha- tocopherol) per calf daily for one month and considered as a treated period. Body weight was recorded at the beginning and the end of each period, and daily gain was calculated for each animal. Blood samples were collected from each animal at the end of each period to determine some blood biochemical parameters and T 3 and T 4 concentrations as well as some immunological indices.The results showed that supplementation of DLY + 600 IU vitamin E to the diet of calves reduced significantly (P 3 and T 4 levels and improved feed efficiency and daily gain. It is concluded that supplementation of growing calves with 15 g DLY + 600 IU vitamin E / calf / day under Egyptian hot summer conditions reduced the effect of heat stress as shown by a decline in RT and modified most blood constituents and thyroid function which leads to an improvement in growing calves

    An experimental study comparing the dynamics of several biochemical markers before and after osteosynthesis, utilizing implants coated with titanium and hafnium nitrides and non-coated implants on rabbits' bones. The Study has been conducted on 30 rabbits of both sexes, at the age of 6-7 months, weighing 2526.5±74.4 gm. Animals underwent open osteotomy of the tibia in the middle third of the diaphysis followed by the intramedullary nailing. The level of alkaline phosphatase, calcium, phosphorus, total protein, glucose, ALT and AST were monitored for 60 days. the use of implants coated with titanium and hafnium nitrides, which have high strength, thermal and chemical stability, was not accompanied by the development of additional negative reactive changes compared to non-coated implants. Nanotechnology used in manufacturing bioinert coatings for implants for osteosynthesis, has made the post-operative period less complicated as reflected by less expressed changing in the markers of bone metabolism and hepatotoxicity.

    In birds, blood samples are often collected from the jugular, medial metatarsal, and basilic vein. Samples are sometimes collected by toe nail clip, but concerns to avoid drawing blood from the nail include pain after nail clips for blood collection, potential differences in complete blood count (CBC) results, and potential contamination with uric acid values. To compare differences in biochemical and hematologic values in blood samples obtained by jugular venipuncture versus toenail clip, blood samples were collected from Moluccan cockatoos (Cacatua moluccensis) (N = 23) and sent to a commercial laboratory for routine CBCs and serum biochemical analysis. Results showed good agreement between venipuncture and nail clip blood samples in red blood cell count, packed cell volume, heterophil count and percentage, lymphocyte count and percentage, aspartate aminotransferase, chloride, creatine phosphokinase, glucose, lactate dehydrogenase, total protein, and uric acid values. Constant bias was found in values of bile acids, cholesterol, and hemoglobin. Proportional bias toward higher values in the jugular sample were found in total white blood cell (WBC) count and inorganic phosphorus. Serum calcium plots revealed a proportional bias toward higher values in the toe nail blood when values were increased. Results suggest some differences in WBC count, bile acids, calcium, cholesterol, hemoglobin, and phosphorus values between blood samples collected by jugular venipuncture and samples collected by toe nail clip, but the differences are mostly minor and, with the possible exception of inorganic phosphorus and marginally elevated or very low WBC counts, are unlikely to affect the use or interpretation of the avian blood panel.

    Full Text Available We analyzed the blood serum of the rainbow trout in relation to various physico-chemical properties of water and diet composition. Fish were reared in two ponds that were supplied by water from different sources. The identified differences in the biochemical parameters are caused by different environmental factors in ponds and different feed composition. Low oxygen values caused by different temperatures is a key stress factor of the noted differences. Statistically significant differences are noted for AST (aspartate aminotransferase, ALT (alanine aminotransferase, triglycerides, urea and iron (0.00. Evident were also different mineral concentrations of Ca and P (0.05 as well as glucose and cholesterol (0.05.

    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.

    A high prevalence of low serum vitamin B-12 concentrations has been reported in studies and surveys in Latin America including Mexico, but the functional consequences are unknown. This randomized controlled trial assessed the response to a high-dose vitamin B-12 supplementation of women in rural Querétaro, Mexico. Participants aged 20-59 y were stratified at baseline to deficient, marginal, and adequate status groups (serum vitamin B-12, 75-148, 149-220, and >220 pmol/L, respectively), and each group was randomized to vitamin B-12 treatment (single dose of 1 mg i.m. then 500 μg/d orally for 3 mo, n = 70) or placebo (n = 62). Measures at baseline and 3 mo included: complete blood count, serum vitamin B-12, holotranscobalamin (holoTC), folate, ferritin, C-reactive protein (CRP), bone alkaline phosphatase, and methylmalonic acid (MMA) and plasma total homocysteine (tHcy). At baseline, 11% of the women were vitamin B-12 deficient and 22% had marginal status. HoloTC was low (271 nmol/L) and tHcy (>12 μmol/L) occurred in 21 and 31%, respectively, and correlated with serum vitamin B-12 (r = -0.28, P alkaline phosphatase. Vitamin B-12 supplementation normalized biochemical indicators of vitamin B-12 status in the treatment group but did not affect the functional outcomes measured.

    Experiment was conducted to investigate the effects of borax, cysteamine and the mixture of two compounds on growth performance, serum biochemical indices, protein turn-over and nitrogen aggradation of sheep by using isotope ( 15 N-Gly) technique, nitrogen balance trial and serum testing. The results showed that both borax and cysteamine could increase the growth performance of sheep, especially the cysteamine and its mixture with borax, which increased average daily feed intake (P 3 ) and levothyroxine (T 4 ) of mixture were higher than that of control group (P<0.05), and the concentrations of growth hormone (GH) and insulin-like growth factors (IGF-1) were also significantly higher than those of control group (P<0.01). There was no significant difference of insulin (INS) between experiment groups and control group (P<0.05). Both mixture and borax contributed to increasing nitrogen retention, net nitrogen utilization, digestibility and biological value. Both borax and cysteamine accelerated protein degradation rate, apparent amino acid utilization rate and net amino acid utilization rate as well as biological value, body protein and oxidation rate, but the former was greater than the later.

    A comparative analysis of the effect of silver nanoparticles (SNP) with a diameter of 14 nm and silver sulfate (SS) on biochemical indices of the state of the organism under the administration of preparations with drinking water to mice F1 CBAxC57Bl (from 0.1 to 500 mg Ag/l for 2 weeks) and nonlinear rats (from 0.01 to 5 mg Ag/l within 6 months) has been performed In the experiment on mice there was found an increase in activity of glutathione reductase (GR) in erythrocytes under the administration of both drugs and reduction of antiradical activity of serum--under the introduction of SNP only. The administration of low doses of SNP in the experiment on rats caused much less pronounced changes in serum markers of the state of the liver; kidneys, protein and lipids metabolism in comparison with equivalent doses of the SS, that as a whole with the qualitative differences on GR activity in erythrocytes satisfactorily was explained by activation of phagocytic cells with nanoparticles. Thus, for the first time the SNP biological effects in animals were shown to be caused both by the exposure to solubilized Ag+ ions and by the response of cells to the surface of the nanoparticles themselves.

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

    Few studies have been done to evaluate anticoagulants for use with blood samples from birds and reptiles. Heparin currently is the most commonly used anticoagulant in practice, but may adversely affect blood cell staining and quantitation. The purpose of this study was to evaluate the effects of lithium heparin, K3-EDTA, and sodium citrate, with and without the addition of albumin, on hematologic variables in macaw (Ara sp) and python (Python molurus bivittatus) blood samples. Blood samples from 10 macaws and 10 Burmese pythons were collected in heparin-coated syringes and placed into tubes containing either lithium heparin, K3-EDTA, or sodium citrate with and without the addition of 0.25 mL of a 22% bovine serum albumin solution. Cell lysis was determined by counting the number of lysed cells/200 WBCs in Wright's-Giemsa-stained blood smears and by qualitative evaluation of pink plasma in microhematocrit tubes. A CBC was done after 3, 12, and 24 hours of storage at 4 degrees C in anticoagulant-containing tubes and results were compared with those obtained at 0 hour for the heparin-coated syringe sample. A biochemical panel also was done at each time point in similarly stored lithium-heparin samples. Hemolysis was significantly increased in citrated samples from both macaws and pythons beginning at 12 hours. At 24 hours, 19 of 30 (63%) macaw samples in all anticoagulants had >100 lysed cells/200 WBCs. There were no significant differences in hematologic values in samples from pythons collected in heparin or EDTA at any time point. No significant differences were found in the number of lysed cells or in other hematologic data in samples with albumin. Glucose concentration decreased and potassium concentration increased significantly over time in heparinized blood samples. Based on the results of this study, whole blood samples anticoagulated with lithium heparin or EDTA should be evaluated within 12 hours (macaws) or 24 hours (pythons) of collection and stored at 4

    Full Text Available The study of genetic markers and identification of new markers make the subject of an increasing number of research projects in various fields such as genetics of immunology, biochemical genetics, molecular genetics, quantitative genetics and the genetic amelioration of animals. The information provided by electrophoresis graphs has been used to determine the frequency of various categories of alleles (for the loci of pre-albumin, transferines and serum amylases, the frequency of various phenotypes and the genetic structure for each and every locus and, simultaneously, for the loci being studied. The discussion over the varieties of serum proteins was carried on for the purpose of using them as genetic markers, in order to appreciate the levels of genetic unity or diversity within the stock of swine that has been studied. A pair of simple alleles has been determined for each of the three loci. When the three loci were studied simultaneously, out of the 27 possible combinations, only 15 have been found. The sample studied has found to be genetically balanced for every of the three loci. However, when the simultaneous study has been applied, the same sample has not been found genetically balanced.

    Plasma biochemical profiles were studied in 112 mature (3 to 5-year-old) healthy cattle comprised of 61 Thai indigenous and 51 Simmental x Brahman crossbred male and cyclic female cattle at Nongkwang (Central Thailand) Livestock Research and Breeding Center, Thailand. Data were analysed for the effect of breed and sex. The results showed that the plasma glucose and gamma-glutamyl transferase (GGT) in the two breeds were significantly (P < 0.05) different. Furthermore, the urea, creatinine, albumin, total protein, aspartate amino transferase (AST), alanine amino transferase (ALT) and alkaline phosphatase (ALP) levels in Thai indigenous were significantly (P < 0.01) higher than in crossbred cattle. However, creatine kinase did not significantly differ in crossbred and indigenous animals. A sex difference was found in glucose level with male Thai indigenous having significantly higher levels (P < 0.05) than the other three groups. Plasma urea concentration in male crossbred cattle was lower than in the other groups (P < 0.05). Female crossbred cattle had significantly (P < 0.05) lower plasma creatinine levels than the other animals. Furthermore, levels of albumin in male and total protein in female crossbred were the lowest (P < 0.05) among the groups. The AST, ALT, ALP and GGT levels were significantly (P < 0.05) different between male and female. Female crossbred cattle had the lowest (P < 0.05) AST and GGT levels, whereas lowest (P < 0.05) ALT and ALP concentration was determined in male individuals of these breeds.

    The CDC’s National Report on Biochemical Indicators of Diet and Nutrition in the US Population (Nutrition Report) is a serial publication that provides ongoing assessment of the population’s nutritional status. The Nutrition Report presents data on blood and urine biomarker concentrations (selected water- and fat-soluble vitamins and nutrients, trace elements, dietary bioactive compounds) from a representative sample of the population participating in the NHANES. The Second Nutrition Report (released in 2012) contains reference information (means and percentiles) for 58 biomarkers measured during all or part of 2003–2006, stratified by age, sex, and race-ethnicity. Where available, we presented cutpoint-based prevalence data during 2003–2006, and data on changes in biomarker concentrations or prevalence since 1999. Blood vitamin concentrations were generally higher in older (≥60 y) compared to younger (20–39 y) adults and lower in Mexican Americans and non-Hispanic blacks compared to non-Hispanic whites. Nearly 80% of Americans (≥6 y) were not at risk for deficiencies in any of the 7 vitamins studied (A, B-6, B-12, C, D, E and folate). Deficiency rates varied by age, sex, and race-ethnicity. About 90% of women (12–49 y) were not at risk for iron deficiency, but only 68% were not at risk for deficiencies in iron and all 7 vitamins. Young women (20–39 y) had median urine iodine concentrations bordering on insufficiency. First-time data are presented on plasma concentrations of 24 saturated, mono- and polyunsaturated fatty acids. Tabulation and graphical presentation of NHANES data in the Second Nutrition Report benefits those organizations involved in developing and evaluating nutrition policy. PMID:23596164

    To investigate the relationship between waist circumference and blood pressure (BP) to determine if waist circumference was an indicator of BP in preschool children. Body weight, height, waist circumference (WC), hip circumference, and blood pressure of 939 3-6-year-old preschool children were collected. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) in obese children were significantly higher than that in normal weight children in both sexes (phigh blood pressure in children of both sexes. Multiple linear stepwise regression analysis using SBP as the dependent variable showed that BMI and WC were significant independent factors that influence high blood pressure adjusted for age, WtHr and waist-to-hip circumference ratio (WHr) in boys. When using DBP as the dependent variable, BMI was the only significant independent factor that influenced high blood pressure adjusted for age, WtHr and WHr, in both sex-es. Waist circumference was independently associated with high blood pressure in boys aged 3-6 years. In addition to BMI, increased waist circumference was found to be an indicator of high blood pressure in the preschool children, especially in boys.

    Patients with type 2 diabetes mellitus develop many complications including osteopenia, which is associated with high fracture risk. Osteocalcin is a non collagenous protein derived from the osteoblasts. Recently, it was found that osteocalcin enhances the pancreatic beta cell proliferation, insulin secretion and protection against type 2 diabetes. Investigation of the association of serum osteocalcin and other bone turnover markers with blood glucose level and diabetes mellitus duration in type 2 diabetic patients. Twenty diagnosed type 2 diabetic patients together with 20 healthy controls were enrolled in this study. Serum osteocalcin, alkaline phosphatase activity and calcium concentrations were measured by commercial ELISA kits. The results showed that type 2 diabetic patients exhibited a significantly lower serum osteocalcin and calcium (p=0.0001 and 0.002 respectively) and a higher alkaline phosphatase (p=0.008) compared to the controls. Multiple linear regression analysis revealed that serum osteocalcin was inversely associated with fasting blood glucose and Diabetes Mellitus duration (β=- 0.018; p=0.007 and β=- 0.085; p=0.014 respectively) in Type 2 diabetic patients. In addition, alkaline phosphatase was positively associated (β=0.828; p=0.015) while serum calcium was negatively associated (β=- 0.046; p=0.048) with Diabetes Mellitus duration. These results refer to the strong association between diabetes and bone turnover markers and call for monitoring of diabetes-associated osteopenia in type 2 diabetic patients.

    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.

    Recombinant human serum albumin (rHSA) incorporating 2-[8-[N-(2-methylimidazolyl)]octanoyloxymethyl]-5,10,15,20-[tetrakis[alpha,alpha,alpha,alpha-o-(1-methylcyclohexanoyl)amino]phenyl]porphinatoiron(II) [albumin-heme (rHSA-heme)] is an artificial hemoprotein which has the capability to transport O(2) in vitro and in vivo. A 20% exchange transfusion with rHSA-heme into anesthetized rats has been performed to evaluate its clinical safety by monitoring the circulation parameters and blood parameters for 6 h after the infusion. Time course changes in all parameters essentially showed the same features as those of the control group (without infusion) and rHSA group (with administration of the same amount of rHSA). Blood biochemical tests of the withdrawn plasma at 6 h after the exchange transfusion have also been carried out. No significant difference was found between the rHSA-heme and rHSA groups, suggesting the initial clinical safety of this entirely synthetic O(2)-carrier as a red-cell substitute.

    Full Text Available Dietary energy for chickens normally includes cereal grains and fat. This innovative study investigated the effect of replacing part of the corn and fat in broiler chicken rations with graded levels of sugar syrup on growth performance and biochemical parameters. 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.

    The study objectives were to investigate the indicators of obesity most associated with high blood pressure in community-dwelling elderly and identify among these which one best discriminates high blood pressure. This is an epidemiological, population, cross-sectional and home-based study of elderly people (≥ 60 years, n = 316) residing in northeastern Brazil. The results showed that the body mass index and the body adiposity index were the indicators more closely associated with high blood pressure in both sexes. Both in female and male genders, body mass index showed high values of specificity and low sensitivity values for discriminating high blood pressure, whereas the body adiposity index showed high sensitivity and moderate specificity values. In clinical practice and health surveillance, it is suggested that both indicators be used as screening tools for hypertension in the elderly. © 2013 Wiley Publishing Asia Pty Ltd.

    Full Text Available There have been conflicting reports regarding the association of perioperative blood transfusion (PBT with oncologic outcomes including recurrence rates and survival outcomes in prostate cancer. We aimed to evaluate whether perioperative blood transfusion (PBT affects biochemical recurrence-free survival (BRFS, cancer-specific survival (CSS, and overall survival (OS following radical prostatectomy (RP for patients with prostate cancer.A total of 2,713 patients who underwent RP for clinically localized prostate cancer between 1993 and 2014 were retrospectively analyzed. We performed a comparative analysis based on receipt of transfusion (PBT group vs. no-PBT group and transfusion type (autologous PBT vs. allogeneic PBT. Univariate and multivariate Cox-proportional hazard regression analysis were performed to evaluate variables associated with BRFS, CSS, and OS. The Kaplan-Meier method was used to calculate survival estimates for BRFS, CSS, and OS, and log-rank test was used to conduct comparisons between the groups.The number of patients who received PBT was 440 (16.5%. Among these patients, 350 (79.5% received allogeneic transfusion and the other 90 (20.5% received autologous transfusion. In a multivariate analysis, allogeneic PBT was found to be statistically significant predictors of BRFS, CSS, and OS; conversely, autologous PBT was not. The Kaplan-Meier survival analysis showed significantly decreased 5-year BRFS (79.2% vs. 70.1%, log-rank, p = 0.001, CSS (98.5% vs. 96.7%, log-rank, p = 0.012, and OS (95.5% vs. 90.6%, log-rank, p < 0.001 in the allogeneic PBT group compared to the no-allogeneic PBT group. In the autologous PBT group, however, none of these were statistically significant compared to the no-autologous PBT group.We found that allogeneic PBT was significantly associated with decreased BRFS, CSS, and OS. This provides further support for the immunomodulation hypothesis for allogeneic PBT.

    Exercise induced cardiac fatigue (EICF) and cardiac dysrhythmias are well described conditions identified in high-level human athletes that increase in frequency with intensity and duration of exercise. Identification of these conditions requires an understanding of normal pre- and post-race cardiac assessment values. The objectives of this study were to (1) characterize selected indices of cardiac function, electrophysiologic parameters, and biochemical markers of heart dysfunction prior to and immediately after high level racing in Thoroughbred horses receiving furosemide; and (2) create pre- and post-race reference values in order to make recommendations on possible screening practices for this population in the future. Thirty Thoroughbred horses were enrolled in the study with an age range of 3-6 years. All horses received furosemide prior to racing. Physical exams, ECGs, and echocardiograms were performed prior to racing (T0) and within 30-60 min following the race (T1). Blood samples were obtained at T0, T1, 4 h post-race (T4) and 24 h after the race (T24). Electrolytes, hematocrit, cardiac troponin I, and partial pressure CO2 values were obtained at all time points. Heart rate was significantly increased post-race compared to baseline value with a median difference of 49 bpm, 95% CI [31,58],(P horses demonstrating regurgitation through the aorta and AV valves was noted. Systolic function measured by fractional shortening increased significantly with a mean difference of 7.9%, 95% CI [4.8, 10.9], (P horse served as its own control, as such the possible effect of regression to the mean cannot be ruled out. The reference intervals generated in this study may be used to identify selected echocardiographic and electrocardiographic abnormalities in racing horses receiving furosemide.

    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.

    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.

    Full Text Available Co-administration of vitamin E and selenium has positive effects on growth performance of avian species, but their effect is not fully elicited in the Japanese quail. Also, controversial reports exist for the effect of vitamin E and selenium on avian performance. This study was designed to investigate the effect of different levels of selenium (0, 0.2 and 0.4 mg/kg and vitamin E (0, 150 and 300 mg/kg in the diet of the Japanese quail. Birds received mesh diet from the start of the study, then selenium and vitamin E were added on day 17. At the end of the study, after food deprivation for 6 hours, Japanese quail (1 male and 1 female were selected and blood samples collected for biochemical investigations and determination of glucose, albumin, total protein, cholesterol, triglyceride, HDL and LDL levels. There was significant decrease in cholesterol, glucose, and triglyceride levels and significant decrease in albumin and total protein levels on day 35 (p

    Blood samples and physical data were collected weekly from a colony of gray wolves (Canis lupus) maintained under natural weather arid light conditions. Sampling over 33 continuous months indicated that hemoglobin, hematocrit, red blood cells, mean corpuscular hemoglobin concentration (MCHC), and thyroxine exhibited consistent circannual patterns of variation in both males and females. Hemoglobin levels peaked at 15-16 g/dl in January in females and at 16-17 g/dl in February in males, and were lowest in August at 10.5-11.5 g/dl (P patterns of hematocrit, red blood cells, and MCHC were similarly timed. Females also had a cyclic pattern of white blood cell counts and body weight; their weight peaked in early February and was lowest in August (P pattern.

    Full Text Available The present study is aimed to assess the influence of artificial photoperiod on the blood cell indices of an Indian catfish, Clarias batrachus(Linn.. Blood samples taken from adult fishes exposed to artificial photoperiod of 24L:0D and 0L:24D for a short period of 24 hrs, were analyzed for total RBC, total WBC, differential leukocyte count (DLC and some physiological variables – glucose and chloride. The total RBC and WBC counts were unaffected by both the artificial photoperiod regimes. However, lymphopenia (p<.05 and neutrophilia (p<.05 were observed under 24L:0D photoperiod. Blood chloride levels were significantly higher (p<.05 in 24L:0D whereas blood glucose levels remained unchanged in both the photoperiod treatments. The 0L:24D photoperiod did not produce any significant change in the blood cell indices neither in the physiological variables. The findings indicate that exposure to continuous light for as short a duration as of 24 hrs elicits stress responses in the leukocyte profile of this nocturnal fish and highlights the role of leukocyte profile as potential stress biomarkers in vertebrates.

    2017-01-01

    Full Text Available The red blood cell distribution width (RDW obtained from a standard complete blood count (CBC is a convenient and inexpensive biochemical parameter representing the variability in size of circulating erythrocytes. Over the past few decades, RDW with mean corpuscular volume (MCV has been used to identify quite a few hematological system diseases including iron-deficiency anemia and bone marrow dysfunction. In recent years, many clinical studies have proved that the alterations of RDW levels may be associated with the incidence and prognosis in many cardiovascular and cerebrovascular diseases (CVDs. Therefore, early detection and intervention in time of these vascular diseases is critical for delaying their progression. RDW as a new predictive marker and an independent risk factor plays a significant role in assessing the severity and progression of CVDs. However, the mechanisms of the association between RDW and the prognosis of CVDs remain unclear. In this review, we will provide an overview of the representative literatures concerning hypothetical and potential epidemiological associations between RDW and CVDs and discuss the underlying mechanisms.

    1985-01-01

    A new method is recommended to interpret the results in radionuclide studies of renal blood flow with the mathematical modelling of transport of a non-diffusible indicator in the blood vessels. The analytic proportions are ascertained between mean transit time of indicator, mean retention time (both at impulse influence and at occurence of any signal at the input) for different forms of transport function, and impulse-shaped retention function of the studied physiological system. By means of external measuring of radioactivity this allows to estimate the mean transit time of the indicator by the studied element of hemodynamics, an index, used in classically physiological studies. The recommended system of physiological indices describes the statistic and dynamic parameters of the vessel network in each kidney adequately. The use of this method showed its efficiency on principle in 7 healthy persons and in 4 patients with clinically manifest kidney diseases. (author)

    Blood culture is considered the "gold standard" for the diagnosis of bacteremia, critical condition with high morbidity and mortality. Because of its importance, it is estimated that the blood culture is a critical test that requires close monitoring on the quality with which the process is performed. The objective of this work is to show the results of the monitoring carried out during the past three years, of 5 quality indicators of blood cultures in the laboratory of the Hospital Clínico de la Pontificia Universidad Católica de Chile, considering pre-analytical, analytical and post-analytical aspects. In the 3 years monitored the mean contamination was 0,7%, 46% of adult bottles had adequate volume, match between Gram stain with final identification was 99.4%, 100% of correct participations were achieved in surveys of external quality control and Gram staining notification before 1 hour was 88.7%. With regard to proposed aims, in 2011 the laboratory complies with all, except the percentage of bottles with appropriate volume of blood inoculated. This indicator is very low and should be corrected as soon as possible since it is known that it is an important condition for optimum performance of blood cultures.

    Full Text Available In this study the effects of mesolites from Moghueieh region and their particles size on performance, blood biochemical parameters and nutrient digestibility in broiler chickens were evaluated. The experiment was conducted on a completely randomized design with three treatments: without mesolite (control and with fine particle mesolite (passed of 1 mm sieve and stay in 0.225 mm sieve or large particle mesolite (passed of 3.36 mm sieve and stay in 1.68 mm sieve. Mesolite added in amount of 2% in diet from 7 day of age. Results indicated that chickens fed large particle mesolite showed reduced performance and fine particle mesolite had no effect on broilers performance. When compared with the controls, body weight gains were significantly lower for birds fed diets containing large particle mesolite. Birds fed large particle mesolite showed higher feed conversion ratio. At the end of the experiment (42 day of age, control group had higher serum TG. Concentration of serum HDL in chickens fed large particle mesolite was higher than control group. Level of serum alkaline phosphatase, glucose, albumin, thyroxin, cholesterol, LDL and uric acid and digestibility of dry matter and protein were not affected by treatments.

  5. 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

    The present study was carried out to determine the effect of ewes breeds on some blood biochemical and hormones levels during mating, pregnancy and post.partum periods. A total number of 42 ewes, 1.5 . 3.5 years of age with body weight ranged between 45 to 55 kg from breeding flock in Research Farm of Nuclear Research Centre, Atomic Energy Authority were used in this study. Animals were divided into two groups according to their breed. The first group included 18 Ossimi breed ewes and the second group included 24 Rahmani breed ewes. Blood samples were collected from both breed at 10, 20, 30, 50, 100, 120, 140, and 145 days up to parturitions and at 30 and 60 days of post. partum. Serum total lipids and cholesterol, progesterone (P4) and estradiol . 17β (E2) were determined. It was found that Ossimi ewes had lower level of both sexual hormones than Rahmani once. Plasma progesterone and estradiol-17 β levels increased gradually as pregnancy time passed reaching its maximum level at the 140th day of the pregnancy period in Rahmani and Ossimi, then decreased during the last 5 days. Additionally, Rahmani ewes had relatively higher mean values of estradiol-17 β at 30th and 60th days compared with Ossime ewes. While, the least squares mean of progesterone decreased in Rahmani ewes compared with Ossime ewes at the same time of estimation. Ossimi ewes having higher means of total lipids (L) and cholesterol (C) than in Rahmani ewes while, the values of L/C ratio were found to be higher in Rahmani ewes than Ossimi ones.

    Absorption and elution experiments showed that it was impossible to separate antibodies against blood group factor M' from antibodies against bovine lymphocyte antigen (BoLA) A16 in an antiserum showing haemolytic activity against M' as well as lymphocytotoxic activity against BoLA-A16....... To elucidate the structural relationship between BoLA-A16 and blood group antigen M', immunoprecipitation experiments on red and white cell lysates isolated from M'-A16 positive and negative cattle were carried out. These results showed that M(r) 44,000 and M(r) 12000 polypeptides can be precipitated from both...... difference in the pI of the immunoprecipitable components of red and white cells was observed. All together, this indicates that either the blood group antigen M' is the BoLA-A16 class I antigen or M' and BoLA-A16 are two different class I polypeptides with the same relative mass, sharing identical epitopes...

    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.

    Results of a four-year study on somatic mutation in peripheral blood lymphocytes among Metro Manila residents as an indicator of exposure to environmental pollution conducted by the Philippine Nuclear Research Institute (PNRI) is presented. The study which involves mutation indexing of 200 blood donors demonstrated very strong correlation between high levels of ambient air pollution and increase incidence of mutation at the specific gene locus in peripheral blood lymphocytes among residents of specific areas in Metro Manila. Using the PNRI adapted protocol to determine incidence of mutation at a specific gene marker, hypoxanthine guanine phosphoribosyl transferase (HGPRT), our database analysis indicated a statistically significant difference between mean mutation index of blood donors residing in an area with lower level of pollution (Las Pinas) compared to those residents living in areas with the highest estimated pollution level (Valenzuela). The results of the statistical analyses should provide regulators the direction in incorporating the data into their pollution abatement program to maximize health impact. Biomarker analysis should play a greater role in the future in the formulation of national environment policies. The temporal variation of these ''aseline data'' as the Philippine moves forward through the next several years in its industrialization program should in itself be a very valuable source of environmental policy instruments.

    This study was carried out to establish biochemical parameters with potential diagnostic value to assess the nutritional status of healthy seabass. For that purpose, triplicate groups of seabass juveniles were submitted to different feeding protocols: fed for 14 days; fed for 7 days followed by 7 days of fasting or fasted for 14 days. At the end of the trial, body, liver and viscera were randomly sampled for proximate composition analysis. Blood was also collected and the following plasma parameters were analyzed by standard clinical methods: glucose; cholesterol; triglycerides; protein; inorganic phosphorus; calcium; magnesium; alkaline phosphatase (ALP); aspartate aminotransferase; lactate dehydrogenase; creatine phosphokinase and lipase. No major effect of feed deprivation on body composition, visceral index, perivisceral and hepatic lipid content were observed, whereas hepatosomatic index and hepatic glycogen were reduced. Previous feeding conditions strongly influenced the plasma parameters in seabass. Comparatively to the fed group, plasma glucose, cholesterol and calcium levels were reduced after 2 weeks of fasting while plasma triglycerides, protein, inorganic phosphorus and ALP attained minimum levels after 1 week of fasting. Overall, enzymatic activity parameters showed higher variability than biochemistry parameters. In conclusion, during short-term starvation (nutritional status of seabass and may be useful to monitor feeding practices in aquaculture. Further studies are, however, required to extend results of this study to other fish size classes.

    To explore the relationship between adiposity and blood pressure (BP)of urban and rural residents in China. The data in the China Health and Nutrition survey (CHNS) in 2006 were utilized. Cross-sectional analysis was carried out on the relationship between blood pressure and body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) among 6433 adult inhabitants aged 18-60 from 9 provinces of China. A multiple regression equation was used for the prediction of blood pressure with these indicators. The average SBP and DBP were increased linearly with the increase of BMI, WC, WHR and WHtR. A statistically significant linear association was found between each adiposity indicator and BP level in separate regression models controlled by age. The regression coefficients were higher in women than that in men. A gain of 0.77 in BMI, 2.43 cm in WC, 2.66% in WHR and 1.54% in WHtR for men and a gain of 0.75, 2.12 cm, 2.54% and 1.53% respectively for women would have a corresponding elevation of 1 mmHg in SBP. Multiple stepwise regression analyses showed that DBP was related with WHtR. There was a stable linear relationship between adiposity indicators and BP. WHtR not a good predicator of SBP and DBP in Chinese adults.

    Head and neck cancer accounts for an estimated 47,560 new cases and 11,480 deaths annually in the United States, the majority of which are squamous cell carcinomas (HNSCC). The overall 5 year survival is approximately 60% and declines with increasing stage at diagnosis, indicating a need for non-invasive tests that facilitate the detection of early disease. DNA methylation is a stable epigenetic modification that is amenable to measurement and readily available in peripheral blood. We used a semi-supervised recursively partitioned mixture model (SS-RPMM) approach to identify novel blood DNA methylation markers of HNSCC using genome-wide methylation array data for peripheral blood samples from 92 HNSCC cases and 92 cancer-free control subjects. To assess the performance of the resultant markers, we constructed receiver operating characteristic (RJC) curves and calculated the corresponding area under the curve (AUC). Cases and controls were best differentiated by a methylation profile of six CpG loci (associated with FGD4, SERPINF1, WDR39, IL27, HYAL2 and PLEKHA6), with an AUC of 0.73 (95% CI: 0.62–0.82). After adjustment for subject age, gender, smoking, alcohol consumption and HPV16 serostatus, the AUC increased to 0.85 (95% CI: 0.76–0.92). We have identified a novel blood-based methylation profile that is indicative of HNSCC with a high degree of accuracy. This profile demonstrates the potential of DNA methylation measured in blood for development of non-invasive applications for detection of head and neck cancer. PMID:22430805

    Full Text Available Background In view of the increasing prevalence of obesity in children, it is necessary to investigate the relative performance of different indicators used for its assessment and health consequences. Objectives To examine concordance between various indicators used for assessing obesity among adolescents and to examine their ability to predict risk of high systolic blood pressure. Design Cross-sectional study, from two schools catering to affluent class. Subjects Children in age 9–16 yr (n = 1146 boys and 1036 girls. Measurements Body weight, height, skinfold thickness at triceps (TSFT and body fat percent by trained investigators and blood pressure measurement by a pediatrician using sphygmomanometer. Results Prevalence of overweight was lowest with criterion of TSFT (11.7% in boys; 7.6% in girls and was highest using criterion of body fat percent (53.7% in boys and 28.4% in girls. Body mass index (BMI had high significant correlation with each of the indicator and with systolic blood pressure (SBP as well, in both sexes. All the indicators with conventional cut offs showed poor sensitivity for predicting high SBP. However, receiver operating characteristics (ROC cut-offs improved sensitivity considerably, but the values were much lower compared to conventional cut-offs. Conclusions There is considerable disparity in the estimates of overweight children obtained by different indicators. Lower values of ROC cut-offs highlights the need for population specific customized classification systems for assessing obesity in view of the probable population differences in relative risks of non-communicable adult diseases.

    The cross-sectional area of a nutrient foramen of a long bone is related to blood flow requirements of the internal bone cells that are essential for dynamic bone remodelling. Foramen area increases with body size in parallel among living mammals and non-varanid reptiles, but is significantly larger in mammals. An index of blood flow rate through the foramina is about 10 times higher in mammals than in reptiles, and even higher if differences in blood pressure are considered. The scaling of foramen size correlates well with maximum whole-body metabolic rate during exercise in mammals and reptiles, but less well with resting metabolic rate. This relates to the role of blood flow associated with bone remodelling during and following activity. Mammals and varanid lizards have much higher aerobic metabolic rates and exercise-induced bone remodelling than non-varanid reptiles. Foramen areas of 10 species of dinosaur from five taxonomic groups are generally larger than from mammals, indicating a routinely highly active and aerobic lifestyle. The simple measurement holds possibilities offers the possibility of assessing other groups of extinct and living vertebrates in relation to body size, behaviour and habitat.

    The present study was formulated to find out the status of important season related thermal stress biomarkers of pure-bred (Hampshire) and crossbred (50% Hampshire × 50% local) pigs under the agro-climatic condition of Assam State, India. The experiment was also aimed to study the role of different level of energy ration (110, 100, and 90% energy of NRC feeding standard for pig) in variation of physiological and biochemical parameters in two genetic groups of pigs in different seasons. The metabolizable energy value were 3260, 2936.5, and 3585.8 kcal/kg in grower ration and 3260.2, 2936.6, and 3587 kcal/kg in finisher ration for normal energy (NE), low energy (LE) and high energy (HE), respectively. Both the genetic group of animals were housed separately under intensive system of management. Each pen was measuring 10' × 12' along with an outer enclosure. Six weaned piglets (almost similar body weight of average 10.55 kg) of each group were kept in a separate pen. However, after attainment of 35 kg body weight, the animals of a group were divided in two pens of three animals each. The present experiment indicated that average ambient temperature during summer months (27.33-29.51 °C) was above the comfort zone for pigs (22 °C). The significantly (P energy (HE) ration during summer season. Serum triiodothyronine (T 3 ) and thyroxine (T 4 ) concentrations were significantly (P energy level of the ration might be helpful to minimize the effects of thermal stress during summer.

    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.

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

    Full Text Available Background: Zinc is an important cause of morbidity, particularly among young children. The dietary, functional, and biochemical indicators should be used to assess zinc status and to indicate the need for zinc interventions. Objective: The purpose of this study was to determine the zinc status and reference intervals for serum zinc concentration considering dietary, functional, and biochemical indicators in apparently healthy children in the Northeast Region of Brazil. Design: The cross-sectional study included 131 healthy children: 72 girls and 59 boys, aged between 6 and 9 years. Anthropometric assessment was made by body mass index (BMI and age; dietary assessment by prospective 3-day food register, and an evaluation of total proteins was performed. Zinc in the serum samples was analyzed in triplicate in the same assay flame, using atomic absorption spectrophotometry. Results: With respect to dietary assessment, only the intake of fiber and calcium was below the recommendations by age and gender. All subjects were eutrophic according to BMI and age classification. Zinc intake correlated with energy (p=0.0019, protein (p=0.0054, fat (p<0.0001, carbohydrate (p=0.0305, fiber (p=0.0465, calcium (p=0.0006, and iron (p=0.0003 intakes. Serum zinc correlated with protein intake (p=0.0145 and serum albumin (p=0.0141, globulin (p=0.0041, and albumin/globulin ratio (p=0.0043. Biochemical parameters were all within the normal reference range. Reference intervals for basal serum zinc concentration were 0.70–1.14 µg/mL in boys, 0.73–1.17 µg/mL in girls, and 0.72–1.15 µg/mL in the total population. Conclusions: This study presents pediatric reference intervals for serum zinc concentration, considering dietary, functional, and biochemical indicators, which are useful to establish the zinc status in specific groups. In this regard, there are few studies in the literature conducted under these conditions, which make it an innovative methodology.

    Full Text Available Extreme climatic conditions and hypobaric hypoxia at high altitude hinders the growth and productivity of chickens. The present study was carried out to examine the effect of aqueous extract of Prunus armeniaca seeds on health, survivability, antioxidants, plasma biochemical parameters, and immune status of broiler chickens at high altitude. Phytochemical analysis of extract revealed the presence of high phenolics, flavonoids, and carotenoids contents. Before the in vivo study, in vitro efficacy evaluation indicated a significant protective effect of the extract in chicken peripheral blood lymphocytes. For in vivo study, experimental groups include control (fed the basal diet, and treatment T1, T2, T3, T4, T5, and T6 which received an aqueous extract of P. armeniaca in drinking water at concentrations of 100, 150, 200, 300, 400, and 800 mg/kg body weight of chicken respectively, along with basal diet for 42 days. Body weight was significantly increased in all treatment groups as compared to control group and the highest body weight was recorded in T3 group. Higher profit was gained in treatment groups due to lesser mortality in chickens. Moreover, chicken in the treatment groups had significantly higher total antioxidant capacity, free radical scavenging activity, interleukin-2, total protein, albumin, globulin level and lower malondialdehyde, interleukin-6, glucose, cholesterol, triglyceride, ALT and AST level as compared to control group. Results suggest that, P. armeniaca extract at 200 mg/kg body weight of chicken, exhibited the beneficial effect on growth performance and survivability rate of broilers and therefore, could be useful as phytogenic feed additive for broiler chickens at high altitude cold desert.

    The identification of regions prone to atherogenesis in the arterial network is compounded by the complex, slow interaction of mechanical and biomechanical processes. In recent times simplifications to the analysis of the near wall hemodynamics have been sought-after to identify plaque prone regions. Mean parameters have been defined to analyze the common fluid mechanical hypotheses considering the role of wall shear stress (WSS) variations in the pathological changes to the endothelium. In this study well known WSS indicators are applied to varying flow conditions of blood-like fluids in a 90-degree arterial bifurcation. The conventional indicators identify two distinct, focal regions that correlate with a known plaque prone location near arterial bifurcations. The results however demonstrate that the interpretation of the indicators can be difficult under varying flow conditions unless complementary parameters are considered simultaneously. A new indicator is also suggested that extracts the peaks of the temporal WSS gradients (PTWSSGs) and is shown to co-incide well with plaque prone regions. The PTWSSG could be used as a complimentary atherogenic indicator in bifurcating arteries, thereby expanding cardiovascular disease studies to the consideration of alternative fluid mechanical hypotheses. The inclusion of a non-Newtonian model is important in predicting the WSS and temporal WSS gradient distributions near the bifurcation due to the separation bubble induced fluctuations in the shear. Atherogenic indicators could be misleading if non-Newtonian effects are excluded. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available ABSTRACT: The objective of this study was to evaluate clinical signs, gas analysis, and metabolic effects of diarrhea in milk-fed calves consuming starter feed containing citrus pulp (CP as a replacement for corn. Twenty-four newborn Holstein male calves were distributed into treatments according to starter composition: (1 0% CP, (2 32% CP, (3 64% CP, on dry matter basis. The calves were housed in individual hutches, with free access to water and concentrate, and received 4 L/d of milk replacer. After diarrhea diagnosis, evaluations of fecal score, score of clinical signs and measurement of physiological parameters were performed three times a day during 3-d. Blood samples were collected for electrolytes, blood gases, and plasma biochemical analysis. Starter feed composition had no negative effect (P>0.05 on fecal score, characteristics of diarrheic stools and on the aggravation of diarrhea clinical signs. Biochemical, blood gases and electrolytes changes, as a function of starter composition, did not resulted (P>0.05 in dehydration, acidosis, or other metabolic disturbance animals. Total lactate and D-lactate plasma concentrations were higher for calves on control and 64% CP, and L-lactate was highest for the 64% CP; however, calves showed no signs of metabolic acidosis. Thermal comfort indexes influenced clinical and physiological parameters (P<0.05. Citrus pulp may replace corn in starter composition without prejudice to intestinal health or metabolism of young diarrheic calves.

    Introduction Haemoglobin is a key determinant of maximal oxygen uptake. This study's objective was to assess total haemoglobin mass (tHb-mass), as well as blood volume and morphological indices in athletes training different sports disciplines. Material and methods This study was conducted on 176 endurance and non-endurance athletes (males and females). tHb-mass, blood volume (BV), plasma volume (PV), and red cell volume (RCV) were determined by optimized carbon monoxide rebreathing method. Haemoglobin concentration (Hb), haematocrit (Hct), red blood count (RBC) were also determined. Results In endurance sports, gender regardless, no significant differences in relative mean values of tHb-mass (12.8–13.1 g/kg – males; 10.4–10.6 g/kg – females), BV (90.8–94.0 ml/kg – males; 82.7–86.9 ml/kg – females), RCV (36.6–38.0 ml/kg – males; 31.1–31.5 ml/kg – females) or of PV in males (54.2–56.4 ml/kg) were observed. The above indices’ relative values, gender regardless, were significantly lower in judo (11.2 ±0.7 g/kg, 81.8 ±5.9 ml/kg, 48.6 ±4.5 ml/kg and 33.1 ±2.0 ml/kg – males; 9.3 ±0.7 g/kg, 74.3 ±5.6 ml/kg, 46.4 ±4.0 ml/kg and 27.9 ±2.1 ml/kg – females) compared to endurance sports (p morphological blood indices in males, whereas this differentiation was found between certain sports in female athletes. Conclusions The lack of differences in tHb-mass, BV, PV and RCV in endurance sports and presence of this differentiation between various sports shows that the types of training might affect levels of mentioned indices. Measurements of tHb-mass and BV parameters prove Hb, Hct and RBC to have limited value for haematological status evaluations. PMID:24273557

    To compare results of biochemical analyses performed on plasma samples obtained from healthy dogs and cats by use of standard and microsample blood collection tubes. Evaluation study. 29 healthy client-owned animals (14 dogs and 15 cats). A blood sample (3 mL) was collected from each animal; 2.5 mL was transferred into a vacuum tube that contained lithium heparin, and 0.5 mL was transferred into a microsample tube that contained lithium heparin. Variables evaluated were albumin, bicarbonate, BUN, calcium, chloride, cholesterol, creatinine, glucose, phosphorus, potassium, sodium, total bilirubin, and total protein concentrations and alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, and creatine kinase activities. Results for the 2 types of tubes in each species were compared by use of Pearson correlation coefficients, Passing-Bablok regression analysis, and Bland-Altman analysis. Data were normally distributed, except for creatine kinase activity of cats. The Pearson correlation coefficient was minimal for total bilirubin concentration in cats and moderate, high, or very high for all other variables. Constant bias for cholesterol and glucose concentration in dogs was identified during Bland-Altman analysis, although the mean difference between types of blood collection tubes was small. No constant or proportional bias for any other variable was revealed by regression analysis or Bland-Altman analysis. Samples obtained from healthy dogs and cats by use of microsample blood collection tubes that contained lithium heparin provided clinically equivalent biochemical results, compared with results for samples obtained by use of standard blood collection tubes, and minimized the total sample volume collected for diagnostic testing.

    Full Text Available High blood pressure (HBP is the leading risk factor for mortality worldwide, but few adolescents know their blood pressure numbers. In youth, overweight is a key risk factorfor HBP. The objective of this study was to evaluate the capability of anthropometric indicators of obesity as predictors of HBP in adolescents. We conducted a cross-sectional study with 1,142 adolescents, both sex, 14-19 yearsold, from Santa Maria, RS, Brazil. The following anthropometric indicators were analyzed: body mass index (BMI, waist circumference (WC, waist-height ratio (WHR, and body adiposity index (BAI. The HBP was identified when above the 95 percentile for blood pressure. We used the analysis of Receiver Operating Characteristic (ROC curves with 95% confidence interval, cutoff points with better accuracy were identified by sensitivity and specificity values. The prevalenceof HBP was 23.6%, and it was higher among boys (33.2%. The highest values for area under de ROC curves were: WHR (0.73; 95% CI: 0.69-0.77 and BAI (0.71;95% CI: 0.67-0.75 for girls. For boys: BMI (0.64; 95%CI: 0.60-0.68 and WHR (0.63; 95%CI: 0.59-0.68. The cutoff points proposed for WHR (boys=0.44; girls=0.45 presented de highest sensitivity and specificity values, both above 60%. The results of this study support that anthropometric measures of adiposity are valid in the identification of HBP in adolescents. Boys and girls with WHR ≥0.44and ≥0.45, respectively, are at high risk for HBP.

  13. Cellular changes in blood indicate severe respiratory disease during influenza infections in mice.

    Full Text Available Influenza A infection is a serious threat to human and animal health. Many of the biological mechanisms of the host-pathogen-interactions are still not well understood and reliable biomarkers indicating the course of the disease are missing. The mouse is a valuable model system enabling us to study the local inflammatory host response and the influence on blood parameters under controlled circumstances. Here, we compared the lung and peripheral changes after PR8 (H1N1 influenza A virus infection in C57BL/6J and DBA/2J mice using virus variants of different pathogenicity resulting in non-lethal and lethal disease. We monitored hematological and immunological parameters revealing that the granulocyte to lymphocyte ratio in the blood represents an early indicator of severe disease progression already two days after influenza A infection in mice. These findings might be relevant to optimize early diagnostic options of severe influenza disease and to monitor successful therapeutic treatment in humans.

    In recent years, {sup 68}Ga-DOTA-peptides positron emission tomography (PET)/CT has been increasingly used to study patients with neuroendocrine tumours (NET). However, performing specialized examinations in the appropriate contest is mandatory for both medical and economic reasons. The aim of the study is to evaluate the potential usefulness of {sup 68}Ga-DOTA-NOC PET/CT in patients with suspected NET. Among the patients undergoing {sup 68}Ga-DOTA-NOC PET/CT at our centre, we reviewed those studied for suspected NET based on the presence of either clinical signs/symptoms or imaging or raised biochemical markers or a combination of these conditions. PET/CT results were compared with clinical and imaging follow-up of at least 1 year or pathology. Overall 131 suspected NET cases were included. The most common condition considered suspicious for NET was the increase of blood markers (66), followed by inconclusive findings at conventional imaging (CI, 41), clinical signs/symptoms (10), equivocal {sup 18}F-fluorodeoxyglucose (FDG) PET (7) or somatostatin receptor scintigraphy (SRS, 4), or a combination of the above (3). PET/CT results were true-positive in 17 cases, true-negative in 112 and false-negative in 2 (overall sensitivity 89.5 %, specificity 100 %). Interestingly, increased blood markers and clinical signs/symptoms were associated with the lowest frequency of true-positive findings (1/66 and 1/10, respectively), while CI findings were confirmed in one third of the cases (13/41). Overall, the incidence of NET in the studied population was 14.5 % (19/131). Our data confirm the good accuracy (98 %) of {sup 68}Ga-DOTA-NOC PET/CT in NET lesion detection. However, our results also suggest that {sup 68}Ga-DOTA-NOC PET/CT may not be routinely recommended in patients with a suspicion of NET based on the mere detection of increased blood markers or clinical symptoms. Positive CI alone or in association with clinical/biochemical findings is on the contrary associated with

    New sources of dioxins and increased dioxin concentrations in the environment, coupled with their increased bioavailability along the food chain and accumulation in adipose tissues, contribute to various adverse long-term biological effects. The purpose of the study was to determine whether tocopherol protects the CNS by decreasing the pro-inflammatory influence of free radicals generated by TCDD; whether acetylsalicylic acid inhibits the production of inflammatory mediators; and whether the combined administration of tocopherol and acetylsalicylic acid to TCDD-exposed rats has a potential CNS-protective effect. The study included 117 rats divided into 8 groups: 75 female and 12 male Buffalo rats aged 8-10 weeks, weighing 140-160 g; as well as 30 female rats aged 6 weeks and weighing 120 g, which were the offspring of females from each study group. In the experiment, the following substances were used: 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), dosed at 5 μg/kg BW and 12.5 μg/kg BW, diluted in a 1% DMSO solution at the concentration of 1 μg/ml; α-tocopherol acetate, dosed at 30 mg/kg BW, in 0.2 ml of oil solution; and acetylsalicylic acid, 50mg/kg BW, suspended in 0.5 ml of starch solution, administered orally using a feeding tube. Pleurisy was induced by an injection of 0.15 ml of 1% carrageenin solution. The use of tocopherol reduces the adverse effects of the inflammatory reaction induced by TCDD. Administering tocopherol improves protein metabolism by reducing protein catabolism, and raises γ-globulin fraction levels. Combined acetylsalicylic acid and tocopherol suppress catabolic processes accompanying inflammation. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available The benefits of dairy consumption seem to extend beyond its significant contribution to ensuring nutrient intake adequacy as indicated by the favourable associations with several health outcomes reported by different studies. The aims of the present study were to examine the associations of milk consumption with fitness, anthropometric and biochemical indices in children and further explore whether the observed associations are attributed to vitamins B2 and B12 derived from milk. A representative subsample of 600 children aged 9–13 years participating in the Healthy Growth Study was examined. Data were collected on children’s dietary intake, using 24 h recalls, as well as on fitness, anthropometric and biochemical indices. Regression analyses were performed for investigating the research hypothesis, adjusting for potential confounders and for B-vitamin status indices (i.e., plasma riboflavin, methylmalonic acid and total homocysteine concentrations, dietary calcium intake and plasma zinc concentrations that could possibly act as effect modifiers. Milk consumption was positively associated with the number of stages performed in the endurance run test (ERT (β = 0.10; p = 0.017 and negatively with body mass index (BMI (β = −0.10; p = 0.014, after adjusting for several potential confounders and effect modifiers. Dietary intakes of vitamin B2 and B12 derived from milk were also positively associated with the number of ERT stages (β = 0.10; p = 0.015 and β = 0.10; p = 0.014 respectively. In conclusion, higher intake of milk as well as vitamin B2 and B12 derived from milk were independently associated with higher cardiorespiratory fitness in Greek preadolescents. The key roles of these B-vitamins in substrate oxidation, energy production, haemoglobin synthesis and erythropoiesis could provide a basis for interpreting these associations. However, further research is needed to confirm this potential interpretation.

    Julian, R, Meyer, T, Fullagar, HHK, Skorski, S, Pfeiffer, M, Kellmann, M, Ferrauti, A, and Hecksteden, A. Individual patterns in blood-borne indicators of fatigue-trait or chance. J Strength Cond Res 31(3): 608-619, 2017-Blood-borne markers of fatigue such as creatine kinase (CK) and urea (U) are widely used to fine-tune training recommendations. However, predictive accuracy is low. A possible explanation for this dissatisfactory characteristic is the propensity of athletes to react to different patterns of fatigue indicators (e.g., predominantly muscular [CK] or metabolic [U]). The aim of the present trial was to explore this hypothesis by using repetitive fatigue-recovery cycles. A total of 22 elite junior swimmers and triathletes (18 ± 3 years) were monitored for 9 weeks throughout 2 training phases (low-intensity, high-volume [LIHV] and high-intensity, low-volume [HILV] phases). Blood samples were collected each Monday (recovered) and Friday (fatigued) morning. From measured values of CK, U, free-testosterone (FT), and cortisol (C) as determined in the rested and fatigued state, respectively, Monday-Friday differences (Δ) were calculated and classified by magnitude before calculation of ratios (ΔCK/ΔU and ΔFT/ΔC). Coefficient of variation (CV) was calculated as group-based estimates of reproducibility. Linear mixed modeling was used to differentiate inter- and intraindividual variability. Consistency of patterns was analyzed by comparing with threshold values (1.1 for all weeks). Reproducibility was very low for fatigue-induced changes (CV ≥ 100%) with interindividual variation accounting for 45-60% of overall variability. Case-wise analysis indicated consistent ΔCK/ΔU patterns for 7 individuals in LIHV and 7 in HILV; 5 responded consistently throughout. For ΔFT/ΔC the number of consistent patterns was 2 in LIHV and 3 in HILV. These findings highlight the potential value of an individualized and multivariate approach in the assessment of fatigue.

    Patients with ventricular assist devices still suffer from high rates of adverse events. Since many of these complications are linked to the flow field within the pump, optimization of the device geometry is essential. To investigate design aspects that influence the flow field, we developed a centrifugal blood pump using industrial guidelines. We then systematically varied selected design parameters and investigated their effects on hemodynamics and hydraulic performance using computational fluid dynamics. We analysed the flow fields based on Eulerian and Lagrangian features, shear stress histograms and six indicators of hemocompatibility. Within the investigated range of clearance gaps (50-500 µm), number of impeller blades (4-7), and semi-open versus closed shroud design, we found association of potentially damaging shear stress conditions with larger gap size and more blades. The extent of stagnation and recirculation zones was reduced with lower numbers of blades and a semi-open impeller, but it was increased with smaller clearance. The Lagrangian hemolysis index, a metric commonly applied to estimate blood damage, showed a negative correlation with hydraulic efficiency and no correlation with the Eulerian threshold-based metric.

    Oocyte quality may be a governing factor in influencing in vitro fertilization (IVF) outcomes. However, morphological evaluation of oocyte quality is difficult in conventional IVF cycles. Follicular-fluid (FF), the site for oocyte growth and development, has not yet been sufficiently explored to obtain a marker indicative of oocyte quality. Anti-Mullerian hormone (AMH) is produced by granulosa cells of preantral and early-antral follicles and is released in FF. To investigate AMH as a biochemical indicator of functional viability/quality of oocyte produced in the FF micro-environmental milieu. Prospective study involving 132 cycles of conventional IVF-embryo transfer (ET) in infertile women. AMH concentration was estimated in pooled FF on day of oocyte pickup. Cycles were sorted into low and high groups according to median (50 (th) centile) values of measurement. Main outcome measure was oocyte viability, which included morphological assessment of oocyte quality, fertilization rate, clinical pregnancy, and implantation rates. Graph-pad Prism 5 statistical package. Low FF AMH group shows significantly higher percentage of top-quality oocytes (65.08 ± 24.88 vs. 50.18 ± 25.01%, P =0.0126), fertilization (83.65 ± 18.38 vs. 75.78 ± 21.02%, P =0.0171), clinical pregnancy (57.57 vs. 16.67%, P >0.0001), and embryo implantation rates (29.79 vs. 7.69%, P >0.0001) compared to high FF AMH group. FF AMH shares an inverse correlation with FF E2 (Pearson r = -0.43, r(2) = 0.18) and clinical pregnancy (Pearson r = -0.46, r(2) = 0.21). Threshold value of FF AMH for pregnancy is >1.750 ng/mg protein. FF AMH is a plausible biochemical indicator of functional viability of oocyte in conventional IVF cycles.

    Correlations were sought between mortality of animals and some biochemical indices. These included elevated levels of deoxycytidine in urine (an indicator of DNA metabolism), elevated levels of histamine, reduced cholinesterase activity in blood, and changes in peripheral blood morphology (reduced erythrocyte and lymphocyte counts). These indices were found to correlate directly with mortality. Regression equations were derived for all the indices studied

    This study examined the effects of estrogen supplementation on markers of neutrophil infiltration and damage in skeletal muscle of rats following ischemia. Male and female gonad-intact rats, with or without 14 days of estrogen supplementation were subjected to two hours of hind-limb ischemia and sacrificed at 24, 48 or 72 hours post-ischemia. Control animals were sacrificed without ischemia. Plantaris and red and white gastrocneimus muscles were removed and assayed for myeloperoxidase (MPO), a marker of neutrophil infiltration, and glucose-6-phosphate dehydrogenase (G6PD) and beta-glucuronidase (betaGLU), as markers of muscle damage. Significant elevations of MPO, G6PD and betaGLU activities were observed at various time points post-ischemia. No systematic differences between genders were noted in any of the measures. Estrogen supplementation in both male and female animals failed to significantly attenuate post-ischemia increases in MPO, G6PD and betaGLU activities in any of the muscles studied and in some cases accentuated activities of some of these measures. Unlike previous findings following exercise in skeletal muscle, this study failed to demonstrate estrogen-induced attenuation of indices of neutrophil infiltration or damage in skeletal muscles of rats up to 72 hours following ischemia. This demonstrates that estrogen may not consistently attenuate neutrophil infiltration and that a number of variables including damage modality, tissue or estrogen level may influence this.

    Full Text Available This study evaluated Jatropha curcas seed cake fermented by Aspergillus niger for use as a potential source of protein in animal feed production. Wistar rats were randomly assigned to 4 groups (A–D, of 3 rats each and fed different protein-rich diets for 4 weeks. Group 1 (control was fed with soybean as a protein source, while Groups 2, 3, and 4 were given feeds supplemented instead with Aspergillus-fermented J. curcas, unfermented J. curcas, and a mix of Aspergillus-fermented J. curcas and soybean (1:1, respectively. At the end of the experiment, rats were sacrificed, and their serum and vital organs were harvested for further analyses. Proximate analyses of the various diet combinations showed significant (P < 0.05 variations in crude protein, crude fibre, ether extract, and ash content. Enzyme assays (alanine transaminase, aspartate transaminase, and alkaline phosphatase in rat serum and tissue homogenates indicate that the detoxification of J. curcas kernel cake by A. niger fermentation is viable and promising. Body weight generally did not differ significantly between the groups, but all rats put on weight in week 1 (Group 2 most strongly. The initial weight gain was followed by a slight decreasing trend in all groups in weeks 2–4, probably due to an adaptation mechanism. One rat fed with the unfermented cake (Group 3 died in week 2, confirming that the cake is not safe for direct consumption until it is processed. Our data support further use of Aspergillus-fermented J. curcas as an alternative protein source in animal feed preparation.

    Contamination of aquatic ecosystems by human and animal wastes is a global concern for water quality. Disclosing fate and transport processes of fecal indicator organism (FIO) in large water bodies is a big challenge due to material intensive and time consuming methods used in microbiological water quality monitoring. In respect of utilization of large surface water resources there is a dearth of rapid microbiological methods that allow a near-real time health related water quality monitoring to be implemented into early warning systems. The detection of enzymatic activities has been proposed as a rapid surrogate for microbiological pollution monitoring of water and water resources (Cabral, 2010; Farnleitner et al., 2001, 2002). Methods such as the beta-D-Glucuronidase assay (GLUC), targeting FIO such as E. coli, were established. New automated enzymatic assays have been implemented during the last years into on-site monitoring stations, ranging from ground- to surface waters (Ryzinska-Paier et al., 2014; Stadler et al., 2017, 2016). While these automated enzymatic methods cannot completely replace assays for culture-based FIO enumeration, they yielded significant information on pollution events and temporal dynamics on a catchment specific basis, but were restricted to stationary measurements. For the first time we conducted ship-borne and automated measurements of enzymatic GLUC activity on large fresh water bodies, including the Columbia River, the Mississippi River and Lake Mendota. Not only are automated enzymatic assays technically feasible from a mobile vessel, but also can be used to localize point sources of potential microbial fecal contamination, such as tributaries or storm drainages. Spatial and temporal patterns of enzymatic activity were disclosed and the habitat specific correlation with microbiological standard assays for FIO determined due to reference samples.

    Very premature infants are at high risk of bleeding complications; however, few data exist on ranges for standard coagulation tests. The primary objective of this study was to measure standard plasma coagulation tests and thrombin generation in very premature infants compared with term infants. The secondary objective was to evaluate whether an association existed between coagulation indices and intraventricular hemorrhage (IVH). Cord and peripheral blood of neonates coagulation factor levels were measured and tissue factor-stimulated thrombin generation was characterized. Control plasma was obtained from cord blood of term neonates. One hundred and sixteen infants were recruited. Median (range) GA was 27.7 (23.7-29.9) weeks and mean (SD) birth weight was 1020 (255) g. Median (5th-95th percentile) day 1 PT, APTT and fibrinogen were 17.5 (12.7-26.6) s, 78.7 (48.7-134.3) s and 1.4 (0.72-3.8) g L(-1) , respectively. No difference in endogenous thrombin potential between preterm and term plasma was observed, where samples were available. Levels of coagulation factors II, VII, IX and X, protein C, protein S and antithrombin were reduced in preterm compared with term plasma. Day 1 APTT and PT were not associated with IVH. In the largest cross-sectional study to date of very preterm infants, typical ranges for standard coagulation tests were determined. Despite long clotting times, thrombin generation was observed to be similar in very preterm and term infants. © 2015 International Society on Thrombosis and Haemostasis.

    Similar to people with metabolic syndrome, bottlenose dolphins (Tursiops truncatus) can have a sustained postprandial hyperglycemia and hyperinsulinemia, dyslipidemia, and fatty liver disease. A panel of potential postprandial blood-based indicators of insulin resistance and metabolic syndrome were compared among 34 managed collection dolphins in San Diego Bay, CA, USA (Group A) and 16 wild, free-ranging dolphins in Sarasota Bay, FL, USA (Group B). Compared to Group B, Group A had higher insulin (2.1 ± 2.5 and 13 ± 13 μIU/ml), glucose (87 ± 19 and 108 ± 12 mg/dl), and triglycerides (75 ± 28 and 128 ± 45 mg/dl) as well as higher cholesterol (total, high-density lipoprotein cholesterol, and very low density lipoprotein cholesterol), iron, transferrin saturation, gamma-glutamyl transpeptidase (GGT), alanine transaminase, and uric acid. Group A had higher percent unmodified adiponectin. While Group A dolphins were older, the same blood-based differences remained when controlling for age. There were no differences in body mass index (BMI) between the groups, and comparisons between Group B and Group A dolphins have consistently demonstrated lower stress hormones levels in Group A. Group A dolphins with high insulin (greater than 14 μIU/ml) had higher glucose, iron, GGT, and BMI compared to Group A dolphins with lower insulin. These findings support that some dolphin groups may be more susceptible to insulin resistance compared to others, and primary risk factors are not likely age, BMI, or stress. Lower high-molecular weight adiponectin has been identified as an independent risk factor for type 2 diabetes in humans and may be a target for preventing insulin resistance in dolphins. Future investigations with these two dolphin populations, including dietary and feeding differences, may provide valuable insight for preventing and treating insulin resistance in humans.

    The Joint Commission accredits health care organisations in the USA as a prerequisite for licensure. In 2011, TJC published seven Patient Blood Management Performance Measures to improve the safety and quality of care. These Measures will provide hospital-specific information about clinical performance. Of the seven TJC PBM Performance Measures, we decided to evaluate PBM-02, "Transfusion indication RBC", at our hospital. Blood transfusion orders were collected from May 2 to August 2, 2011 and the data analysed. Of the 724 consecutive red blood cell transfusion orders, 694 (96%) documented both clinical indication and pre-transfusion haemoglobin/haematocrit results. The leading transfusion indication (47% of total) was "high risk patients with pre-transfusion Hb of change by introducing the single-unit transfusion policy. The majority (96%) of the transfusion orders met The Joint Commission criteria by providing both transfusion indication and pre-transfusion Hb and/or Hct values. Our transfusion guidelines recommend single-unit red blood cell transfusions with reassessment of the patient after each transfusion for need to receive more blood. Although most (72%) initial orders followed our transfusion guidelines, 70% of patients who received a single unit initially went on to receive more blood (some in excess of 10 units). Our objective data may be helpful in evaluating blood ordering practices at our hospital and in identifying specific clinical services for review.

    Atomic Energy Centre, Dhaka under the Bangladesh Atomic Energy Commission was recently awarded a research contract from the International Atomic Energy Agency to investigate the levels of micronutrients (K, Ca, Mn, Fe, Ni, Cu, Zn) and pollutants (As, Pb) in health indices (hair, blood, etc.) to study their interactions and impacts on the nutritional status of Bangladeshi population. The project was scheduled to start in December 2001 and to be completed by November 2002. To date, sampling and sample preparation techniques for heavy metal analysis in hair and blood using XRF/PIXE have been investigated, and some preliminary work on sample analysis has been performed. It indicates that both PIXE and XRF methods can be used for the determination of nutritionally important trace metals in health indices after a simple sample treatment for volume reduction either by oven or freeze drying. Results of Biochemical assessment of nutritional status of Bangladeshi pre-school children under normal and malnutrition conditions from a previous study has been given in the Results section of this paper. There has been found a positive correlation of malnutrition with some nutritional parameters such as fasting blood glucose, serum total protein, serum total albumin, and serum Cu and Zn levels. Hair Zn level had no significant correlation (p>0.05) with serum Zn level but hair Cu level had a positive correlation with serum Cu level. The trace element concentrations in hair of both normal and malnourished children in the age group of 1-5 years, as studied do not show any regular dependence on nutritional status of the subjects. Only the low copper content in the hair of the malnourished group can possibly be linked with nutritional disorders. (author)

    Diagnosis and treatment of infective endocarditis (IE) is still a challenge for physicians. Group of patients with the worst prognosis is treated in Intensive Cardiac Care Unit (ICCU). Etiologic agent can not be identified in a substantial number of patients. The aim of study is to find differences between patients with blood culture negative infective endocarditis (BCNIE) and blood culture positive infective endocarditis (BCPIE) treated in ICCU by comparing their clinical course and laboratory parameters. Retrospective analysis of 30 patients with IE hospitalized in ICCU Swietokrzyskie Cardiac Centre between 2010 and 2016. This group consist of 26 men (86,67%) and 4 women (13,3%). Mean age was 58 years ±13. Most of the cases were new disease, recurrence of the disease was observed in 2 cases (6,7%). 8 patients (26,7%) required artificial ventilation, 11 (36,7%) received inotropes and 6 (20%) vasopresors. In 14 (46,7%) cases blood cultures was negative (BCNIE), the rest of patients (16, 53,3%) was blood cultures - positive infective endocarditis (BCIE). Both of the groups were clinically similar. There were no statistically significant differences in incidence of cardiac implants, localization of bacterial vegetations, administered catecholamines, antibiotic therapy, artificial ventilation, surgical treatment, complication and in-hospital mortality. Incidence of cardiac complications in all of BCNIE cases and in 81,3% cases of BCPIE draws attention, but it is not statistically significant difference (p=0,08). There was statistically significant difference in mean BNP blood concentration (3005,17 ng/ml ±2045,2 vs 1013,42 ng/ml ±1087,6; p=0,01), but there were no statistically significant differences in rest of laboratory parameters. BCNIE group has got higher mean BNP blood concentration than BCPIE group. There were no statistically significant differences between these groups in others laboratory parameters, clinical course and administered antibiotic therapy

    To examine the utility of waist-to-height ratio to identify risk of high blood pressure when compared to body mass index and waist circumference in South Indian urban school children. Secondary data analysis from a cross-sectional study. Urban schools around Bangalore, India. 1913 children (58.1% males) aged 6-16 years with no prior history of chronic illness (PEACH study). Height, weight, waist circumference and of blood pressure were measured. Children with blood pressure ?90th percentile of age-, sex-, and height-adjusted standards were labelled as having high blood pressure. 13.9% had a high waist-to-height ratio, 15.1% were overweight /obese and 21.7% had high waist circumference. High obesity indicators were associated with an increased risk of high blood pressure. The adjusted risk ratios (95% CI) of high systolic blood pressure with waist-to-height ratio, body mass index and waist circumference were 2.48 (1.76, 3.47), 2.59 (1.66, 4.04) and 2.38 (1.74, 3.26), respectively. Similar results were seen with high diastolic blood pressure. Obesity indicators, especially waist-to-height ratio due to its ease of measurement, can be useful initial screening tools for risk of high blood pressure in urban Indian school children.

    The study of the frequency of chromosomal aberrations per cell is the tool used in Biological dosimetry studies. Using dose-effect calibration curve obtained in our laboratory, we can evaluate the radioprotector effect of the EEP (ethanolic extract of propolis) in cultures in vitro. Propolis is the generic name for resinous substance collected by honeybees. The results showed a reduction in chromosomal aberrations's frequency of up to 50 %. The following study consisted of analyzing human peripheral blood lymphocytes exposed to 2 Gy γ rays, in presence and absence of EEP, the change in the frequency of chromosome aberrations was analysed with biological dosimetry. The protection against the formation of dicentric and ring was dose-dependent, but there seemed to be a maximum protection, i.e. a further increase in the concentration of EEP does not show additional protection. This work studies the effect of the EEP of the cellular cycle using the mitotic and cellular proliferation index, as an alternative for the screening cytostatic activity. The results indicate that the lymphocytes which were cultures in presence of EEP exhibited a significant and dependent-concentration decrease in mitotic index and proliferation kinetics. The possible mechanisms involved in the radioprotective influence of EEP are discussed. (authors)

    The relationship among iron status, ferritin, and folate levels, and the possible contribution of folate measurement in the prediction of iron response in hemodialysis patients, have not been assessed. In addition to serum ferritin and transferrin saturation (TSAT), serum and red blood cell (RBC) folate levels were evaluated as indices for intravenous iron therapy responsiveness in 60 hemodialysis patients. Patients were classified as iron responders or nonresponders depending on whether they exhibited a rise in hemoglobin above 1 g/dl after administration of 1 g of iron sucrose. An inverse relation between serum ferritin concentration and RBC folate levels was found in iron responders (n=26, r=-0.62, p<0.001) but not in nonresponders (n=34, r=0.07, p=nonsignificant). Only serum and RBC folate levels could predict iron response in patients with ferritin levels above 150 microg/l (n=25), with a sensitivity of 83.3% and a specificity of 94.7%. Our findings suggest that RBC folate concentration is inversely related with ferritin levels in iron-responsive but not in non-responsive hemodialysis patients. Serum and RBC folate concentration seems to predict response to iron administration better than serum ferritin or TSAT in patients with ferritin levels above 150 microg/l; therefore, in these patients, it might be used to guide iron management.

    Full Text Available ABSTRACT BACKGROUND Small bowel bleeding is a leading indication for small bowel capsule endoscopy. The Suspected Blood Indicator (SBI is a software feature directed to automatically detect bleeding lesions during small bowel capsule endoscopy. OBJECTIVE We aimed to assess SBI diagnostic accuracy for small bowel haemorrhage or potentially bleeding lesions during small bowel capsule endoscopy for small bowel bleeding. Methods - Single-centre retrospective study including 281 consecutive small bowel capsule endoscopy performed for small bowel bleeding during 6 years. The investigators marked lesions with high bleeding potential (P2, such as angioectasias, ulcers and tumours, as well as active bleeding during regular small bowel capsule endoscopy viewing with PillCam SB2(r. All small bowel capsule endoscopy were independently reviewed by another central reader using SBI. RESULTS Among the 281 patients, 29 (10.3% presented with active haemorrhage while 81 (28.9% presented with a P2 lesion. The most frequently observed P2 lesions were angioectasias (52, ulcers (15, polyps (7 and ulcerated neoplasias (7. SBI showed a 96.6% (28/29 sensitivity for active small bowel bleeding, with a 97.7% negative predictive value. Regarding P2 lesions, the SBI displayed an overall sensitivity of 39.5%, being highest for ulcerated neoplasias (100%, but significantly lower for angioectasias (38.5% or ulcers (20.0%. CONCLUSION Although SBI sensitivity for the automatic detection of potentially bleeding lesions was low, it effectively detected active small bowel bleeding with very high sensitivity and negative predictive value.

    Evaluation of a neonate for suspected early neonatal sepsis routinely includes blood tests such as complete blood count, C-reactive protein (CRP) and culture. In order to obviate the need for venepuncture, we prospectively compared these tests in paired samples from umbilical cord and peripheral venous blood drawn during the first hours after birth in both preterm and term infants. Paired blood samples were studied from asymptomatic neonates with risk factors for early sepsis. Data were collected on maternal and neonatal factors that may have influenced the correlation between the tests. Three hundred fifty pairs of samples were studied. Significant correlation between umbilical cord and peripheral venous samples was found for white blood cell (WBC; r = 0.683) and platelets (PLT) (r = 0.54). Correlation for hemoglobin was lower (r = 0.36). No cases of early neonatal sepsis were detected. However, contamination rates were 12% in umbilical cord blood and 2.5% in peripheral venous blood cultures. WBC rose after birth and the 90th percentile rose from 22 500 in umbilical cord blood to 29 700 in peripheral blood. Screening for sepsis with umbilical cord CBC may be useful provided normal ranges are adjusted accordingly.

    Abstract Hypertension is fast becoming a major public health problem across sub-Saharan Africa. We sought to determine the prevalence of high blood pressure (BP) and associated risk factors as indicator of preclinical hypertension in a rural Gambian population. We analyzed data on 6160 healthy Gambians cross-sectionally. Attention was given to 5 to <18-year olds (N = 3637), as data from sub-Saharan Africa on this young age group are scarce. High BP was defined as systolic blood pressure (SBP) above the 95th percentile for age-sex specific height z scores in <18-year olds employing population-specific reference values. Standard high BP categories were applied to ≥18-year olds. In <18-year olds, the multivariable analysis gave an adjusted high BP prevalence ratio of 0.95 (95% confidence interval [CI] 0.92–0.98; P = 0.002) for age and 1.13 (95% CI 1.06–1.19; P < 0.0001) for weight-for-height z score (zWT-HT); sex and hemoglobin were not shown to affect high BP. In adults age 1.05 (95% CI 1.04–1.05; P < 0.0001), body mass index z score 1.28 (95% CI 1.16–1.40; P < 0.0001), hemoglobin 0.90 (95% CI 0.85–0.96; P < 0.0001) and high fasting glucose 2.60 (95% CI 2.02–3.36; P < 0.0001, though the number was very low) were confirmed as risk factors for high BP prevalence; sex was not associated. The reported high BP prevalence and associated risk factors in adults are comparable to other studies conducted in the region. The observed high BP prevalence of 8.2% (95% CI 7.4–9.2) in our generally lean young Gambians (<18 years) is alarming, given that high BP tracks from childhood to adulthood. Hence there is an urgent need for further investigation into risk factors of pediatric high BP/hypertension even in rural African settings. PMID:28353557

    To study relations between disturbances of cerebral venous circulation and parameters of 24-h blood pressure monitoring in hypertensive patients. A total of 72 patients aged 28 to 60 years with essential hypertension of stage II have undergone 24-h blood pressure monitoring and MR-venography of the brachiocephalic veins on a low-field MR-tomograph using 2D TOF angiography. Symptoms of disturbed cerebral venous circulation were found in 60% patients. Major venous collectors were asymmetric in 79.2% patients, 40.3% had marked asymmetry, 14% had severe asymmetry. Disturbances of venous outflow significantly more frequently occurred in non-dippers and night-peakers as well as in high variability of blood pressure. Patients with marked asymmetry of venous collectors had elevated nocturnal systolic and diastolic blood pressure, high load indices of nocturnal systolic and diastolic pressure, a low degree of nocturnal fall of blood pressure. Disturbance of venous cerebral outflow in hypertensive patients is closely related with alterations of a circadian profile of blood pressure: circadian index of blood pressure, variability of blood pressure.

    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.

    In most cases cerebrospinal fluid (CSF) leaks are iatrogenic and caused by medical interventions, such as lumbar puncture, peridural anesthesia and surgical interventions on the spine, However, spontaneous cerebral hypotension is currently detected more frequently due to improvements in diagnostic possibilities but often the cause cannot be clarified with certainty. There are various diagnostic tools for confirming the diagnosis and searching for the site of CSF leakage, such as postmyelography computed tomography (postmyelo-CT), indium 111 radioisotope cisternography and (myelo) magnetic resonance imaging (MRI), which show different sensitivities. In accordance with own experience native MRI with fat-saturated T2-weighted sequences is often sufficient for diagnosing CSF leakage and the site. For the remaining cases an additional postmyelo-CT or alternatively myelo-MRI is recommended. In some patients with spontaneous cranial hypotension multiple CSF leaks are found at different spinal levels. The main symptom in most cases is an orthostatic headache. While post-puncture syndrome is self-limiting in many cases, spontaneous CSF leakage usually requires blood patch therapy. A lumbar blood patch can be safely carried out under guidance by fluoroscopy. In the case of a cervical or dorsal blood patch, CT guidance is recommended, which ensures epidural application of the blood patch and minimizes the risk of damaging the spinal cord. Despite a high success rate at the first attempt with a blood patch of up to 85 %, some cases require repeating the blood patch. A targeted blood patch of a CSF leak should generally be favoured over a blindly placed blood patch; nevertheless, if a CSF leak cannot be localized by CT or MRI a therapeutic attempt with a lumbar blood patch can be carried out. After a successful blood patch intracranial hygromas and pachymeningeal enhancement in the head show fast regression; however, epidural hygromas of the spine can persist for a period of

    Hypertensive disorders of pregnancy (HDP) remain a leading cause of maternal and perinatal morbidity and mortality worldwide. In Australia approximately 10% of all pregnancies are affected by HDP. There is growing evidence that endothelial damage caused by HDP remains after pregnancy and has long term consequences on maternal health. The aim of our research was to determine the association between HDP and risk of having high blood pressure in later life. Self-reported data regarding a physician's diagnosis of HDP and of high blood pressure later in life were obtained from women recruited from the 45 and Up Study, Australia. Relative risks (converted from odds ratios) and 99% confidence intervals were estimated using logistic regression, adjusting for demographic and lifestyle characteristics. A total of 82,164 women were included in the study, of which 9,845 reported having HDP. Women who had HDP had a significantly increased risk of having high blood pressure later in life compared to women who did not have HDP (adjusted relative risk of 2.05, 99% CI 1.99-2.11, phigh blood pressure 6.3 years (99% CI 5.85-6.66, phigh blood pressure compared to women who have a healthy pregnancy. Women with HDP should be monitored closely in the years following pregnancy for early identification and intervention of high blood pressure. Copyright © 2010. Published by Elsevier B.V.

    Male cotton rats (Sigmodon hispidus) were studied at three industrial waste sites near Houston, Texas, to determine whether various morphological, biochemical, and histopathological indices provided evidence of contaminant exposure and toxic insult. Only modest changes were detected in cotton rats residing at waste sites compared with reference sites. No single parameter was consistently altered, except hepatic cytochrome P-450 concentration which was lower ( [Formula: see text] ) at two waste sites, and tended to be lower ( [Formula: see text] ) at a third waste site. Elevated petroleum hydrocarbon concentrations were detected in rats at one waste site, but contaminant burdens of rats from the other sites were unremarkable. Unlike rats captured in summer, those trapped in winter exhibited hepatocellular hypertrophy and up to a 65% increase in liver: body weight ratio, cytochrome P-450 concentration, and activities of aniline hydroxylase, aryl hydrocarbon hydroxylase, and glutathione S-transferase. Although genotoxicity has been previously documented in cotton rats residing at two of the waste sites, biomarkers in the present study provided little evidence of exposure and damage

    A method to determine the spectrophotometric biochemical oxygen demand (BOD(sp)) was studied with high sensitivity and reproducibility by employing 2,6-dichlorophenolindophenol (DCIP) as a redox color indicator, the yeast Saccharomyces cerevisiae, and a temperature-controlling system providing a three-consecutive-stir unit. The absorbance of DCIP decreased due to the metabolism of organic substances in aqueous samples by S. cerevisiae. Under optimum conditions, a calibration curve for glucose glutamic acid concentration between 1.1 and 22mg O(2) L(-1) (r=0.988, six points, n=3) was obtained when the incubation mixture was incubated for 10min at 30 degrees C. The reproducibility of the optical responses in the calibration curve was 1.77% (average of relative standard deviations; RSD(av)). Subsequently, the characterization of this method was studied. The optical responses to pure organic substances and the influence of chloride ions, artificial seawater, and heavy metal ions on the sensor response were investigated before use with real samples. Measurements of real samples using river water were performed and compared with those obtained using the BOD(5) method. Finally, stable responses were obtained for 36 days when the yeast cell suspension was stored at 4 degrees C (response reduction, 89%; RSD(av) value for 9 testing days, 8.4%).

    Full Text Available The research work was aimed at investigating physiological, biochemical, analgesic and anesthetic indices of dogs anesthetized with propofol-ketamine and maintained with repeat bolus and constant infusions of propofol. Eight dogs, assigned to two groups (n=4, were used in this study. All dogs were pre-medicated with atropine (at 0.03 mg/kg bwt and xylazine (at 2 mg/kg bwt. Anesthesia was induced by a concurrent administration of propofol (at 4 mg/kg bwt and ketamine (at 2.5 mg/kg bwt. Maintenance of anesthesia in Group 1 was done with a repeat bolus of propofol (at 2 mg/kg bwt, while in Group 2 it was done with a constant infusion of propofol (at 0.2 mg/kg bwt/min. Gastrotomy was performed in both groups, and anesthesia was maintained for 60 min. Physiological, analgesic, anesthetic parameters and plasma glucose concentration were measured. There was no significant (P>0.05 difference found in the analgesia and pedal reflex scores, durations of analgesia and recumbency, recovery time and standing time between the groups. The heart rate, respiratory rate and rectal temperature reduced significantly (P0.05 between the groups. In conclusion, both maintenance protocols are suitable for dogs, although the repeat bolus technique produces marked cardiopulmonary depression.

    Full Text Available The objective of the present study was to investigate the effects of methionine (Met supplementation on growth performance of cubs, nutrient digestibility, nitrogen metabolism and serum biochemical parameters of female blue foxes. One hundred primiparous female blue foxes that were similar in breeding date, pedigree, age, and weight were selected for the trial. The foxes were randomly assigned to four groups (n = 25 each group and fed diets supplemented with Met at 2 (Met2, 4 (Met4, 6 (Met6 and 8 g/kg (Met8, respectively, for 40 days. Our data showed that body weights at 20 and 40 d were significantly higher in the Met4 group than in the Met2 group (P < 0.05. The Met4 group also had the highest apparent digestibility of dry matter and crude protein compared with either the Met2, Met6, or Met8 group (P < 0.05. The serum Met and isoleucine (Ile concentrations were significantly higher in the Met4 group than in the Met6 or Met8 group (P < 0.05. In summary, these data indicate that supplementary Met improves growth performance of cubs likely due to increased crude protein and dry matter and increased nitrogen retention of female blue foxes. The optimal amount of Met supplementation is 10 g/kg basal diet.

    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.

    In order to determine the clinical conditions of Japanese Black (JB) cattle with growth retardation, we determined the changes of body growth, blood profiles of metabolism and hormones caused by intensified nutrition (sufficient total digestible nutrients and digestible crude protein for a target daily gain set at 1.2-1.3 kg/day) in three cattle. The daily gain (DG) was increased during the intensified period (Intense) compared with the preparation period (Pre), but the DG in the Intense period was 36-66% of the target DG. Serum albumin, total cholesterol, insulin and IGF-1 increased during the Intense period compared with the Pre period. Serum GH showed high levels in the Pre period, whereas it showed lower levels in the Intense period. These results suggested that the present growth retarded cattle had abnormalities in their metabolic systems and lacked nutrient absorption.

    There is concern that transgenic Bt-crops carry genes that could have undesirable effects on natural and agro-ecosystem functions. We investigated the effect of Bt-cotton (expressing the Cry 1Ac protein) on several microbial and biochemical indicators in a sandy loam soil. Bt-cotton (MRC-6301Bt) and its non-transgenic near-isoline (MRC-6301) were grown in a net-house on a sandy clay loam soil. Soil and root samples were collected 60, 90, and 120 days after sowing. Soil from a control (no-crop) treatment was also included. Samples were analysed for microbial biomass C, N and P (MBC, MBN, MBP), total organic carbon (TOC), and several soil enzyme activities. The microbial quotient (MQ) was calculated as the ratio of MBC-to-TOC. The average of the three sampling events revealed a significant increase in MBC, MBN, MBP and MQ in the soil under Bt-cotton over the non-Bt isoline. The TOC was similar in Bt and non-Bt systems. Potential N mineralization, nitrification, nitrate reductase, and acid and alkaline phosphatase activities were all higher in the soil under Bt-cotton. Root dry weights were not different (P > 0.05), but root volume of Bt-cotton was higher on 90 and 120 days than that of non-Bt cotton. The time of sampling strongly affected the above parameters, with most being highest on 90 days after sowing. We concluded from the data that there were some positive or no negative effects of Bt-cotton on the studied indicators, and therefore cultivation of Bt-cotton appears to be no risk to soil ecosystem functions.

    To determine the utility of capillary blood ketone levels as an indicator of inadequate intake of breast milk in the early postnatal period. Levels of capillary blood beta-hydroxybutyrate (βOHB), the main ketone body in the blood, were measured with a bedside ketone meter in 585 full-term neonates aged 48-95 hours who were breastfed exclusively. Relationships between weight-loss percentage, blood sodium, glucose, pH, partial pressure of carbon dioxide, base-deficit levels, and βOHB levels were investigated. The diagnostic accuracy of βOHB for predicting excessive weight loss (weight loss ≥10% of birth weight) and hypernatremic dehydration (blood sodium level ≥150 mEq/L) was determined. βOHB levels were correlated positively with weight-loss percentage and blood sodium levels and were correlated negatively with blood glucose levels. The diagnostic accuracy of βOHB was 0.846 (optimal cut off, 1.55 mmol/L; sensitivity, 80.9%, specificity, 74.0%) for predicting excessive weight loss and 0.868 (optimal cut off, 1.85 mmol/L; sensitivity, 94.3%; specificity, 69.9%) for predicting hypernatremic dehydration according to the area under the receiver operating characteristic curve. Multiple logistic analysis revealed that βOHB and weight loss percentage were the only independent predictors of hypernatremic dehydration. Increases in βOHB levels also were associated with worsening metabolic acidosis and hypocapnia. High βOHB levels were associated with inadequate intake of breast milk in the early postnatal period. The use of bedside capillary blood ketone levels may be clinically useful as an indicator of dehydration, energy depletion, and acid-base imbalance in breastfeeding infants in the early postnatal period.

    Full Text Available Epidemiological studies suggest a relationship between blood lipids and immune-mediated diseases, but the nature of these associations is not well understood. We used genome-wide association studies (GWAS to investigate shared single nucleotide polymorphisms (SNPs between blood lipids and immune-mediated diseases. We analyzed data from GWAS (n~200,000 individuals, applying new False Discovery Rate (FDR methods, to investigate genetic overlap between blood lipid levels [triglycerides (TG, low density lipoproteins (LDL, high density lipoproteins (HDL] and a selection of archetypal immune-mediated diseases (Crohn's disease, ulcerative colitis, rheumatoid arthritis, type 1 diabetes, celiac disease, psoriasis and sarcoidosis. We found significant polygenic pleiotropy between the blood lipids and all the investigated immune-mediated diseases. We discovered several shared risk loci between the immune-mediated diseases and TG (n = 88, LDL (n = 87 and HDL (n = 52. Three-way analyses differentiated the pattern of pleiotropy among the immune-mediated diseases. The new pleiotropic loci increased the number of functional gene network nodes representing blood lipid loci by 40%. Pathway analyses implicated several novel shared mechanisms for immune pathogenesis and lipid biology, including glycosphingolipid synthesis (e.g. FUT2 and intestinal host-microbe interactions (e.g. ATG16L1. We demonstrate a shared genetic basis for blood lipids and immune-mediated diseases independent of environmental factors. Our findings provide novel mechanistic insights into dyslipidemia and immune-mediated diseases and may have implications for therapeutic trials involving lipid-lowering and anti-inflammatory agents.

    Intracellular glutathione in its reduced state is a principal cellular biomolecule with antioxidant activity. Glutathione and homocysteine metabolism are closely associated. As both oxidative stress and hyperhomocystinemia are associated with hypertension, we assessed the relationships between these variables. An observation-based case-control study, performed at a university teaching hospital. Middle-aged male patients with untreated uncomplicated essential hypertension (mean +/- standard deviation age 53.0 +/- 7.2 years, n = 48) before any treatment and controls with similar age distributions (age 51.6 +/- 5.5 years, n = 28) were evaluated. In all subjects, the plasma levels of homocysteine, lipids, creatinine, protein, and glucose were measured. Reduced and oxidized glutathione and folic acid were measured from red blood cells (RBC). The hypertensive patients had decreased levels of red blood cell reduced glutathione (RBC-GSH) and increased levels of oxidized glutathione, which resulted in elevated ratio of oxidized/reduced glutathione as compared to controls (P < 0.001). Plasma homocysteine levels were significantly higher in the hypertensive patients versus the age-matched controls (P < 0.004). In the hypertensive patients, RBC-GSH correlated inversely with systolic blood pressure, serum creatinine, protein and RBC folic acid. No correlation was detected between RBC-GSH and homocysteine. In the controls, RBC-GSH correlated inversely with homocysteine, RBC folic acid and creatinine. According to multiple regression, in the hypertensive patients RBC-GSH was related to systolic blood pressure, hemoglobin, plasma homocysteine, creatinine and protein. Such a relationship was not detected for the controls. In untreated hypertensive patients both homocysteine and systolic blood pressure are associated with intracellular oxidative stress as determined by RBC-GSH.

    The aim of the present study was to evaluate the effects of occupational exposure to lead (Pb) and cadmium (Cd) on markers of oxidative stress in glazers in tile industries. Total antioxidant capacity (TAC), malondialdehyde (MDA), and the activity of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) were determined in the blood of 80 subjects, including 40 glazers and 40 nonexposed subjects. Mean levels of blood Cd (8.90 ± 2.80 µg/L) and blood Pb (62.90 ± 38.10 µg/L) of glazers showed a significant increase compared with the control group. In the serum of glazers, the level of MDA was significantly higher and the level of TAC was significantly lower than the control group. We have noted a disturbance in the levels of antioxidants by a significant increase in the CAT activity and a significant decrease in the activities of SOD and GPx in the serum of glazers compared with the controls. Correlation analysis demonstrated that the serum MDA level and CAT activity were positively associated with the blood levels of Pb and Cd. Also, GPx and SOD were negatively correlated with blood Cd levels. The study clearly indicated that co-exposure to Cd and Pb can induce oxidative stress in glazers, resulting in increased lipid peroxidation and altered antioxidant enzymes.

  9. Changes in the blood-nerve barrier after sciatic nerve cold injury: indications supporting early treatment

    2015-01-01

    Full Text Available Severe edema in the endoneurium can occur after non-freezing cold injury to the peripheral nerve, which suggests damage to the blood-nerve barrier. To determine the effects of cold injury on the blood-nerve barrier, the sciatic nerve on one side of Wistar rats was treated with low temperatures (3-5°C for 2 hours. The contralateral sciatic nerve was used as a control. We assessed changes in the nerves using Evans blue as a fluid tracer and morphological methods. Excess fluid was found in the endoneurium 1 day after cold injury, though the tight junctions between cells remained closed. From 3 to 5 days after the cold injury, the fluid was still present, but the tight junctions were open. Less tracer leakage was found from 3 to 5 days after the cold injury compared with 1 day after injury. The cold injury resulted in a breakdown of the blood-nerve barrier function, which caused endoneurial edema. However, during the early period, the breakdown of the blood-nerve barrier did not include the opening of tight junctions, but was due to other factors. Excessive fluid volume produced a large increase in the endoneurial fluid pressure, prevented liquid penetration into the endoneurium from the microvasculature. These results suggest that drug treatment to patients with cold injuries should be administered during the early period after injury because it may be more difficult for the drug to reach the injury site through the microcirculation after the tissue fluid pressure becomes elevated.

    The main objective of this work was to investigate the impact of dietary chromium supplementation on growth indices, carcass yield, and some hematological and biochemical blood parameters of growing Japanese quails subjected to heat stress. A total of 360 unsexed 2-week-old Japanese quail chicks were used in a 2 × 3 factorial arrangement that had two ambient temperatures (23 ± 2 and 33 ± 2 °C) and three dietary chromium (0.00, 500, and 1000 μg Cr/kg diet as chromium picolinate). For induction of heat stress, the room temperature was set at 33 ± 2 °C from 2 to 6 weeks of age. Results showed that body weight, body weight gain, and feed intake were decreased for birds subjected to heat stress condition during 2 to 4 and 2 to 6 weeks of age. Feed conversion was not significantly (P > 0.05) affected by high ambient temperature throughout the experiment. Carcass, dressing, liver, and heart percentages were not influenced by the ambient temperature or dietary chromium or their combinations. Significant temperature × chromium combinations were observed for hemoglobin value (P = 0.025) and packed cell volume (P = 0.001). Cholesterol and glucose in plasma were increased (P = 0.004 or 0.022) in quails subjected to heat stress condition. Plasma measurements of total proteins, albumin, globulin, lipids, glucose, and A/G ratio of quail chicks were not influenced (P > 0.05) by chromium, while cholesterol was increased with increasing chromium level (P = 0.033). High ambient temperature or dietary chromium levels or their interactions did not (P > 0.05) affect plasma levels of aspartate transaminase (AST), alanine transaminase (ALT), triiodothyronine (T3), thyroxin (T4), or T3/T4 ratio of growing quails. From these observations, it can be concluded that dietary chromium supplementation of growing Japanese quail subjected to heat stress condition could beneficially affect growth performance and carcasses, as well as modulate the hematological

    Gated blood pool scan is frequently used for evaluating the change in cardiac function in various cardiac diseases. But resting gated blood pool scan using only LVEF as a cardiac index has been consistently shown to have a low sensitivity, which is about 50%, in detecting coronary artery disease. So it is recommended to compare exercise gated blood pool scan to resting gated blood pool scan. Exercise tests, however, are not always possible, especially in patients with musculoskeletal diseases, recent myocardial infarction and in elderly persons. We studied the usefulness of resting gated blood pool scan using multiple indices in evaluating the patients with coronary artery disease. Studied cases were 185 patients with coronary artery disease (angina pectoris 31, myocardial infarction 154) and 25 normals with low likelihood of coronary artery disease. We used 99m Tc-labeled RBC, 740 MBq labeled by in vivo method. The data were evaluated by Micro DELTA computer program. The results were as following: 1) The ejection rates (PER, AER) and filling rates (PFR, AFR) were different in normals and patients with angina pectoris or myocardial infarction. 2) Mean phase angle, ejection rates and filling rates could separate normals from coronary artery disease patients with normal LVEF. 3) Regional ejection fraction was decreased at the site of the infarct in patients with myocardial infarction. 4) Peak filling rate was the most detectable index in evaluation of cardiac function in patients with coronary artery disease. 5) The threshold at 1.5 standard deviation of normal range was considered as the most reliable cut-off value from ROC analysis. These data suggest that the resting gated blood pool scan has an important role in the evaluation of cardiac functional changes using various cardiac indices in patients with coronary artery disease.

    Global synchronization across specialized brain networks is a common feature of network models and in-vivo electrical measurements. Although the imaging of specialized brain networks with blood oxygenation sensitive resting state functional magnetic resonance imaging (rsfMRI) has enabled detailed study of regional networks, the study of globally correlated fluctuations with rsfMRI is confounded by spurious contributions to the global signal from systemic physiologic factors and other noise sources. Here we use an alternative rsfMRI method, arterial spin labeled perfusion MRI, to characterize global correlations and their relationship to correlations and anti-correlations between regional networks. Global fluctuations that cannot be explained by systemic factors dominate the fluctuations in cerebral blood flow. Power spectra of these fluctuations are band limited to below 0.05 Hz, similar to prior measurements of regional network fluctuations in the brain. Removal of these global fluctuations prior to measurement of regional networks reduces all regional network fluctuation amplitudes to below the global fluctuation amplitude and changes the strength and sign of inter network correlations. Our findings support large amplitude, globally synchronized activity across networks that require a reassessment of regional network amplitude and correlation measures.

    OBJECTIVE To determine the effects of stacked wedge pads and chains applied to the forefeet of Tennessee Walking Horses on behavioral and biochemical indicators of pain, stress, and inflamation. ANIMALS 20 Tennessee Walking Horses. PROCEDURES Horses were randomly assigned to 2 treatment groups: keg shoes (control; n = 10) or stacked wedge pads and exercise with chains (10). Ten days before treatment application, an accelerometer was attached at the left metatarsus of each horse to record daily activity. Horses were exercised for 20 minutes daily, beginning on day -7. On day 0, exercise ceased, the forefeet were trimmed, and the assigned treatment was applied. From days 1 through 5, horses were exercised as before. Blood samples for measurement of plasma cortisol, substance P, and fibrinogen concentrations were collected on days -5, 1, and 5 before and after exercise and every 30 minutes thereafter for 6 hours. RESULTS No significant differences in plasma concentrations of cortisol, substance P, and fibrinogen were detected between groups. Although lying behaviors changed after shoes were applied, these behaviors did not differ significantly between groups. Shoeing appeared to have altered behavior to a greater extent than did the type of treatment applied. CONCLUSIONS AND CLINICAL RELEVANCE Application of stacked wedge pads and chains to the forefeet of horses for a 5-day period as performed in this study evoked no acute or subacute stress or nociceptive response as measured. Although these findings should not be extrapolated to the long-term use of such devices in Tennessee Walking Horses performing the running walk, the data should be considered when making evidence-based decisions relating to animal welfare and the use of stacked wedge pads and chains.

    Alpha-thalassemia is known to be prevalent in the Eastern region of Saudi Arabia. There are no large scale reports regarding the effect of alpha-thalassemia on red cell indices of cord blood from Saudi Arabia. Similarly, there are reports regarding the interaction of alpha-thalassemia and the sickle-cell gene in relation to red cell indices in cord blood. To address these issues, we undertook a study on neonatal cold blood samples. In a prospective study, cord blood samples from 504 neonates from the Qatif area of the Eastern Province of Saudi Arabia were analyzed for complete blood counts (CBC) and cellulose acetate Hb electrophoresis. Hb S was confirmed by citrate agar Hb electrophoresis. There were 243 case samples with normal Hb electrophoresis (Hb A 27.2+- 7% and Hb F 72.6+-7.7%). Their mean Hb (g/dL), RBC (x10/L), Hct (%), MCV (pg), MCHC (g/dL), RDW-SD (fl) and RDW-CV (%) were 15.05+-1.6, 4.5+-0.5, 47.4+-5.3, 106+-8, 33.6+-2.3, 31.8+-1.7, 69.2+-9.5 and 17.9+-1.7, respectively. There were 136 cases with alpha-thalassemia trait (alphaTT), 57 cases with sickle cell trait (SCT) and 50 cases of sickle cell trait with alplha-thalassemia trait (SCT/ alphaTT). There were ten cases of Hb H disease (6 definite), including one with sickle cell disease (SCD) and two with SCT, Hb Bart's 23.9%-43.6%; four probable with Hb Bart's 10.9%-16.1% and one with SCT. The effect on red cell parameters in Hb H disease were most pronounced. In addition, there seven cases of SCD, four of whom had coexistent alpha-thalassemia trait (SCD/alphaTT). The prevalence of alpha-thalassemia in this cohort of Saudi population was 39.99%. Hb H disease appeared as common as SCD. Sickle cell gene was seen in 23.4% of neonatal samples. Apha-thalassemia gene significantly reduces MCH, MCV, RDW-SD, Hct, Hb and increase RBC count in both normal or sickle cell trait neonates. Generally, the variation of red cell parameters is directly proportional to the amount of Hb Bart's in the cord blood. Sickle cell

    The pain perception to distension of the oesophagus can be explained by activation of receptors responding to mechanical deformation or to distension-induced ischaemia. The aim of this study was to develop a new method for detection of changes in segmental blood flow during distension based...... on measurement of heat transfer. A bag was distended in the distal oesophagus of six healthy subjects followed by cooling or heating of the bag fluid to 5 or 60 degrees C. After equilibrium, the temperature was allowed to change back to body temperature. The temperature was recorded together with intraluminal...... ultrasound imaging, allowing assessment of the heat transfer properties at different bag volumes. The heat transfer constants were higher after heating the bag than after cooling the bag (Tukey, P

    Full Text Available Lead as one of the environmental pollutants can threats the life of living creatures in many ways. In this study, hematological effects of chronic toxicity of the lead acetate in adult male rats through measurement of the lead concentration in the blood of animal’s heart by atomic absorption as well as hematological analyses and differential cell count were investigated. Results showed that lead concentration in the treatment group was significantly higher than that of the control groups (P<0.001, and basophilic stippling, Howell-Jolly bodies, decreased RBC count (anemia, increased leukocyte count (leukocytosis, monocytosis, eosinopenia, neutrophilia, and thrombocytosis were observed in the test group (P<0.001. It is concluded that microcytic hypochromic anemia can be attributed to the interaction of lead with iron and copper metabolism and increased leukocyte count may be linked to the inflammatory effects of lead on lymphatic organs.

In electronic patient records, many diagnostic and procedural codes are registered, but unfortunately, it is usually not specified which one is the reason for transfusion. Therefore, a method is needed to determine the most likely indication for transfusion in an automated way.Study design and methods: An algorithm to identify the most likely transfusion indication was developed and evaluated against a gold standard based on the review of medical records for 234 cases by 2 experts. In a second step, information on misclassification was used to fine-tune the initial algorithm. The adapted algorithm predicts, out of all data available, the most likely indication for transfusion using information on medical specialism, surgical procedures, and diagnosis and procedure dates relative to the transfusion date.Results: The adapted algorithm was able to predict 74.4% of indications in the sample correctly (extrapolated to the full data set 75.5%.

    Full Text Available Blood-brain barrier (BBB disruption is one of the hallmarks of multiple sclerosis (MS. It is incompletely understood whether BBB disruption is the initial MS event leading to MS lesion formation or whether it is merely a consequence of cellular infiltration in the central nervous system (CNS. The presence of gadolinium enhancing (Gd+ lesions on serial brain MRI scans is frequently used to evaluate BBB disruption. The presence of Gd enhancement has therefore been used as a reference for most works evaluating promising biomarkers of BBB disruption that are reviewed here. These promising biomarkers include cytokines and chemokines, and their receptors, cell surface markers, and matrix metalloproteinases and their natural inhibitors. At this time, none of these markers have been shown as sensitive as the presence of Gd enhancement to reflect BBB disruption. However, MRI scanning is not only unpractical and expensive; it may also under represent the overall extent of BBB disruption. Developing new MS biomarkers that are sensitive and specific for BBB disruption could 1 improve the monitoring of disease activity; 2 improve the monitoring of response to MS therapies which target BBB disruption; and 3 advance our understanding of dynamic MS processes participating in BBB disruption.

The fowls were divided in three groups (26 females and 3 males in each group. They were reared in a free-range management system with elements of organic production. The experimental treatments were as followed: first (control group without dietary supplement, second group with 100 mg Zinteral 35 per kg diet containing 35 mg/kg zinc oxide, third group with the same amount of Zinteral 35 together with 250 mg vitamin C per kg diet. During the three periods with different ambient temperature, the hens supplemented either with zinc alone (second group or co-administered zinc + vitamin C (third group had significantly lower levels of plasma corticosterone (P<0.001, serum cholesterol (P<0.05 and glucose (P<0.05 than those from the first (control group. The differences between the third and the first groups were bigger versus those between the second and the first groups. For the entire period (March 1 and June 21, egg production was higher by 2.22 % and 4.60 % in the second and third groups respectively in comparison to the first group. The combination of 100 mg Zinteral 35 and 250 mg vitamin C per 1 kg diet exhibited a synergistic effect in reducing cold and heat stress in laying hens and increased their egg production.

    Full Text Available Abstract Background The pyrethroid class of insecticides, including deltamethrin, is being used as substitutes for organochlorines and organophosphates in pest-control programs because of their low environmental persistence and toxicity. This study was aimed to investigate the impact of commonly used pesticides (deltamethrin on the blood and tissue oxidative stress level in catfish (Clarias gariepinus; in addition to the protective effect of α-tocopherol on deltamethrin induced oxidative stress. Catfish were divided into three groups, 1st control group include 20 fish divided into two tanks each one contain 10 fish, 2nd deltamethrin group, where Fish exposed to deltamethrin in a concentration (0.75 μg/l and 3rd Vitamin E group, Fish exposed to deltamethrin and vitamin E at a dose of 12 μg/l for successive 4 days. Serum, liver, kidney and Gills were collected for biochemical assays. Tissue oxidative stress biomarkers malondialdhyde (MDA and catalase activity in liver, kidney and gills tissues, serum liver enzymes (ALT and AST, serum albumin, total protein, urea and creatinine were analysed. Results Our results showed that 48 h. exposure to 0.75 μg/l deltamethrin significantly (p  Conclusions It could be concluded that deltamethrin is highly toxic to catfish even in very low concentration (0.75 μg/l. Moreover the effect of deltamethrin was pronounced in the liver of catfish in comparison with kidneys and gills. Moreover fish antioxidants and oxidative stress could be used as biomarkers for aquatic pollution, thus helping in the diagnosis of pollution. Adminstration of 12 μg/l α-tocopherol restored the quantified tissue and serum parameters, so supplementation of α-tocopherol consider an effective way to counter the toxicity of deltamethrin in the catfish.

    Full Text Available Aim: The present study was conducted to explore the effect of supplemental heat on mortality rate, growth performance, and blood biochemical profiles of indigenous Ghungroo piglets in sub-tropical cold and humid climatic conditions of Tripura, a state of the north eastern hill (NEH region of India. Materials and Methods: The experiment was conducted on 38 indigenous Ghungroo piglets from birth up to 60 days of age. Among the 38 piglets, 19 piglets were provided with supplemental heat ranging between 17.0°C and 21.1°C for the period of the first 30 days and thereafter between 24.1°C and 29.9°C for the next 30 days. The other 19 piglets were exposed to natural environmental minimum temperatures ranging between 7.2°C and 15.0°C during the first 30 days and then between 18.5°C and 25.5°C for the next 30 days. Results: The supplemental heat resulted in 10.6% reduction of piglet mortality from the 2nd till the 7th day of age. These beneficial effects could be related with the lower (p<0.05 plasma glutamate pyruvate transaminase (GPT and cortisol levels and higher (p<0.05 plasma alkaline phosphatase (AP concentrations in heat supplemented group compared to control group. Plasma AP, GPT, glucose, triiodothyronine, and luteinizing hormone concentrations decreased (p<0.05 gradually with the advancement of age in both control and supplemental heat treated piglets. Conclusion: Supplemental heat could be beneficial since it is related to a reduction of piglet mortality during the first week of life under farm management system in the sub-tropical climate of NEH region of India.

    Objective To determine the impact of maternal obesity and gestational weight gain across pregnancy on fetal indices of inflammation and iron status. Study design Eighty-five healthy term newborns delivered via elective cesarean were categorized by 2 maternal body mass index (BMI) thresholds; above or below 30 kg/m2 or above or below 35 kg/m2. Umbilical cord plasma levels of C-reactive protein, interleukin (IL)-6, tumor necrosis factor (TNF)-α, ferritin, and hepcidin were assayed. Cytokines released by phytohemagglutinin-stimulated umbilical cord mononuclear cells (MNCs) were assayed. Results Maternal class II obesity, defined as BMI of 35 kg/m2 and above, predicted higher C-reactive protein and TNF-α in umbilical cord plasma (Pumbilical cord iron indices were associated with maternal obesity. When ferritin was low, IL-6 was higher (P < .04), but this relationship was present primarily when maternal BMI exceeded 35 kg/m2 (P < .03). Ferritin was correlated with hepcidin (P < .0001), but hepcidin was unrelated to either maternal BMI or inflammatory indices. Conclusions Class II obesity and above during pregnancy is associated with fetal inflammation in a threshold fashion. Although maternal BMI negatively impacted fetal iron status, hepcidin, related to obesity in adults, was related to iron status and not obesity in fetuses. Pediatricians should be aware of these relationships. PMID:26970931

    Full Text Available Background: The youth of this era are the sufferings of overweight and obesity because of sedentary lifestyle, eating habits, altered pattern of behaviour and mental stress. Abdominal obesity is a predominant risk factor of cardiovascular disease. With this background, this study was proposed to correlate abdominal obesity with blood pressure (BP in young adults. Materials and Methods: A total of 205 young male adults of 20–25 years were selected from various local educational institutions. Estimation for waist circumference (WC, hip circumference (HC and BP recording was done. Waist–hip ratio (WHR was calculated from WC and HC. Recording of BP was performed between 8 and 9 am after 5–10 min rest. On the basis of WC, participants were classified into two groups, i.e., WC ≤90 cm and WC >90 cm. On the basis of WHR, participants were classified into two groups, i.e., WHR <0.90 and WHR ≥0.90. Results: In the present study, we found that the participants those WC and WHR above the cut-off value shown significantly more BP (both systolic and diastolic than normal. Likely, the pulse pressure was higher in participants WC and WHR above cut-off value but not significant. We found a positive correlation between WC and WHR with BP. Conclusion: This study suggested that WC and WHR have a positive correlation with BP and hence concluded that adults with abdominal obesity are at higher risk to develop CVD in their future life.

    Blood indicators are used as a tool to diagnose metabolic disorders. The present work was conducted to study the relationships among blood indicators of lipomobilization and hepatic function in high-yielding dairy cows. Two groups of Holstein cows were studied: 27 early lactation cows and 14 mid lactation cows from four different herds with similar husbandry characteristics in Galicia, Spain. Blood samples were obtained to measure beta-hydroxybutyrate (BHB), non-esterified fatty acids (NEFA), triglycerides (TG), and the activity of aspartate transaminase (AST) and gamma-glutamyl transferase. Cows in early lactation had higher levels of BHB and NEFA than mid lactation cows. High lipomobilization (NEFA > 400 µmol/L) was detected in 67% and 7% of early lactation and mid lactation cows, respectively, while subclinical ketosis (BHB > 1.2 mmol/L) was detected in 41% and 28% of the early lactation and lactation cows, respectively. TG concentrations were low in all cows suffering subclinical ketosis and in 61% of the cows with high lipomobilization. During early lactation, 30% of cows suffered hepatic lipidosis as detected by levels of AST. Compromised hepatic function was observed in early lactation cows as shown by lower concentrations of glucose, total protein, and urea.

    Blood pressure (BP) may be adversely affected by a variety of sleep disturbances, including sleep fragmentation, hypoxemia, respiratory disturbances, and periodic limb movements. We aim to identify which polysomnography indices are most strongly and consistently associated with systolic and diastolic blood pressure (SBP, DBP) levels in a population-based sample. Cross-sectional analysis of data from 2,040 participants in the Multi-Ethnic Study of Atherosclerosis (MESA) who underwent polysomnography at MESA Exam 5 in 2011-2013. Multisite cohort study. Participants were mean age 68 y (54% females; 28% African American, 24% Hispanic, 11% Chinese). Thirty-two candidate polysomnography predictors were identified representing the domains of breathing disturbance frequency, hypoxemia, sleep architecture, and periodic limb movements. Cluster analysis was used for variable reduction. Statistical models, adjusted for potential confounders, were derived using stepwise regression. Final models were selected using cross-validation techniques. The apnea-hypopnea index (AHI) defined using a 4% desaturation hypopnea criterion (AHI4P) was most consistently associated with SBP level. The AHI and periodic limb movement index (associated with arousals; PLMIA) were significantly associated with DBP. Estimated adjusted differences in SBP and DBP levels between an individual with no sleep apnea (AHI4P = 0) and one with moderately severe sleep apnea (AHI4P = 30) were 2.2 mm Hg and 1.1 mm Hg, respectively. Each 10-unit increase in the PLMIA was associated with an increase in DBP of 1.2 mm Hg. Our results support the use of a currently recommended apnea-hypopnea index definition as a marker of blood pressure risk and indicate that measurement of limb movements with arousals is also independently associated with diastolic blood pressure. © 2015 Associated Professional Sleep Societies, LLC.

    Full Text Available Preeclampsia (PE is an obstetric disorder with high morbidity and mortality rates but without clear pathogeny. The dysfunction of the blood coagulation-fibrinolysis system is a salient characteristic of PE that varies in severity, and necessitates different treatments. Therefore, it is necessary to find suitable predictors for the onset and severity of PE.We aimed to evaluate blood coagulation parameters and platelet indices as potential predictors for the onset and severity of PE.Blood samples from 3 groups of subjects, normal pregnant women (n = 79, mild preeclampsia (mPE (n = 53 and severe preeclampsia (sPE (n = 42, were collected during early and late pregnancy. The levels of coagulative parameters and platelet indices were measured and compared among the groups. The receiver-operating characteristic (ROC curves of these indices were generated, and the area under the curve (AUC was calculated. The predictive values of the selected potential parameters were examined in binary regression analysis.During late pregnancy in the normal pregnancy group, the activated partial thromboplastin time (APTT, prothrombin time (PT, thrombin time (TT and platelet count decreased, while the fibrinogen level and mean platelet volume (MPV increased compared to early pregnancy (p<0.05. However, the PE patients presented with increased APTT, TT, MPV and D-dimer (DD during the third trimester. In the analysis of subjects with and without PE, TT showed the largest AUC (0.743 and high predictive value. In PE patients with different severities, MPV showed the largest AUC (0.671 and ideal predictive efficiency.Normal pregnancy causes a maternal physiological hypercoagulable state in late pregnancy. PE may trigger complex disorders in the endogenous coagulative pathways and consume platelets and FIB, subsequently activating thrombopoiesis and fibrinolysis. Thrombin time and MPV may serve as early monitoring markers for the onset and severity of PE

    Whole body retention (WBR) and urinary excretion (UE) of 99m Te-diphosphonate were determined in 161 healthy adults and the results were compared to accepted biochemical markers of bone turnover. WBR was corrected for total body bone mineral (TBBM) and UE from forearm bone mineral content (BMC). Both uncorrected and corrected retention measurements were highly significantly correlated to the biochemical markers (P<0.001), but the r values were low (0.22-0.64). All bone turnover variables demonstrated considerably higher levels of bone turnover in postmenopausal women than in premenopausal women (P<0.001), whereas the variables were unchanged with age in men. The correction of WBR for TBBM and UE for BMC increased the validity of the retention methods and the two calculations gave exactly the same results on a group basis, both demonstrating significantly higher bone turnover in women than in men in each age group (P<0.05-P<0.001). All the turnover variables were measured in a group of perimenopausal women (n=33). The data clearly demonstrated that bone turnover is menopause dependent, whereas age in itself is of minor significance. (orig.)

    Full Text Available Background: Systolic blood pressure recovery (rSBP is of prognostic value for predicting the survival and co-morbidity rate in patients with coronary artery disease (CAD. This study investigated the association between rSBP and exercise indices after complete cardiac rehabilitation program (CR in a population-based sample of patients undergoing coronary artery bypass grafting (CABG.Methods: The sample population consisted of 352 patients who underwent pure CABG. The patients underwent standard symptom-limited exercise testing immediately before and also after the completion of the CR sessions. rSBP was defined as the ratio of the systolic blood pressure at 3 minutes in recovery to the systolic blood pressure at peak exercise.Results: An abnormal baseline rSBP after exercise was a strong predictor of exercise parameters in the last session, including metabolic equivalents (β = -0.617, SE = 0.127, p value < 0.001 and peak O2 consumption (β = -1.950, SE = 0.363, p value < 0.001 measured in the last session adjusted for baseline exercise characteristics, demographics, function class, and left ventricular ejection fraction.Conclusion: The current study strongly emphasizes the predictive role of baseline rSBP after exercise in evaluating exercise parameters following CR. This baseline index can predict abnormal METs value, peak O2 consumption, post-exercise heart rate, and heart rate recovery after a 24-session CR program.

    Individual variation of examination performance depends on many modifiable and non-modifiable factors, including pre-examination anxiety. Medical students' quality of life (QoL) and certain biochemical changes occurring while they are preparing for examinations has not been explored. We hypothesize that these parameters would determine the examination performance among medical students. Fourth-year medical students (n=78) from the University of Ruhuna, Sri Lanka, were invited. Their pre- and post-exam status of QoL, using the World Health Organization Quality of Life (WHOQOL-BREF) questionnaire, and the level of biochemical marker levels (i.e., serum levels of thyroid profile including thyroglobulin, cortisol and ferritin) were assessed. Differences between the scores of QoL and serum parameters were compared with their performance at the examination. The mean QoL score was significantly lower at pre-exam (56.19±8.1) when compared with post-exam (61.7±7.1) levels (pexam (0.9 mIU/L; interquartile range 0.74-1.4 mIU/L) was significantly lower (p=0.001) when compared with the level after the exam (median of 2.7 mIU/L; IQR 1.90-3.60). The mean±SD fT4 level was significantly higher before the exam (19.48±0.4 pmol/L at study entry vs. 17.43±0.3 pmol/L after the exam; pexam (43.15 (23.5-63.3) µg/L) was significantly lower (p≤0.001) when compared with after-exam status (72.36 (49.9-94.9) µg/L). However, there was no difference in mean serum cortisol levels (16.51±0.7 at pre-exam and 15.88±0.7 at post-exam, respectively; p=0.41). Students had higher fT4 and low ferritin levels on pre-exam biochemical assessment. It was evident that students who perform better at the examination had significantly higher QoL scores at each domain tested through the questionnaire (Physical health, Psychological, Social interaction and Environment). The higher the QoL scores, the better the grades were. It was also found that students who failed exhibited profound differences in the

    Full Text Available At present, gold nanoparticles (GNPs are widely used in biomedical applications such as cancer diagnostics and therapy. Accordingly, the potential toxicity hazards of these nanomaterials and human safety concerns are gaining significant attention. Here, we report the effects of prolonged peroral administration of GNPs with different sizes (2, 15 and 50nm on morphological changes in lymphoid organs and indicators of peripheral blood of laboratory animals. The experiment was conducted on 24 white mongrel male rats weighing 180–220g, gold nanospheres sizes 2, 15 and 50nm were administered orally for 15 days at a dosage of 190μg/kg of animal body weight. The GNPs were conjugated with polyethylene glycol to increase their biocompatibility and bioavailability. The size-dependent decrease of the number of neutrophils and lymphocytes was noted in the study of peripheral blood, especially pronounced after administration of GNPs with size of 50nm. The stimulation of myelocytic germ of hematopoiesis was recorded at morphological study of the bone marrow. The signs of strengthening of the processes of differentiation and maturation of cellular elements were found in lymph nodes, which were showed as the increasing number of immunoblasts and large lymphocytes. The quantitative changes of cellular component morphology of lymphoid organs due to activation of migration, proliferation and differentiation of immune cells indicate the presence of immunostimulation effect of GNPs.

    Monocytes play a crucial role in immune response against Mycobacterium tuberculosis infection. The purpose of this current study was to investigate the morphology present on monocytes in peripheral blood from patients with active pulmonary tuberculosis (APTB) and the laboratory performance of the changes for discriminating cases from normal healthy subjects (NHS). A total of 71 peripheral blood samples from patients with APTB, and 65 samples from NHS were analyzed. The mean monocyte volume with its distribution width and mean monocyte conductivity as well as monocyte light scatter were detected by VCS technology used on the LH750 hematology analyzer. Correlations of these changes with the serum cytokine level in the immune alterations were further evaluated. The Receiver operating characteristic curve (ROC) analysis was used to highlight the clinical implication. In APTB patients, the mean monocyte volume showed significant difference associated with an evident elevation in the mean monocyte volume distribution width compared to those in NHS. Furthermore, the mean monocyte volume had positive relationship with the serum level of interleukine-1β response to M. tuberculosis infection. Simultaneous measurement of the mean monocyte volume and its distribution width was able to distinguish active infection with an excellent sensitivity of 84.5% and specificity of 90.5% comparable to those obtained from pro-inflammatory cytokine interleukine-6 identifying APTB with great accuracy. The morphological changes of monocytes particular increased mean volume may be a potential indicator to predict active tuberculosis infection. Copyright © 2018. Published by Elsevier B.V.

    A study was conducted to assess the effect of combined stresses (thermal and nutritional) on endocrine and biochemical responses in Malpura ewes. Twenty eight adult Malpura ewes (average body weight 33.56 kg) were used in the present study. The ewes were divided into four groups viz., GI ( n = 7; control), GII ( n = 7; thermal stress), GIII ( n = 7; nutritional stress) and GIV ( n = 7; combined stress). The animals were stall fed with a diet consisting of 60% roughage and 40% concentrate. GI and GII ewes were provided with ad libitum feeding while GIII and GIV ewes were provided with restricted feed (30% intake of GI ewes) to induce nutritional stress. GII and GIV ewes were kept in climatic chamber at 40°C and 55% RH for 6 h a day between 1000 hours and 1600 hours to induce thermal stress. The study was conducted for a period of two estrus cycles. The parameters studied were Hb, PCV, glucose, total protein, total cholesterol, ACP, ALP, cortisol, T4, T3, and insulin. Combined stress significantly ( P ewes. It can be concluded from this study that two stressors occurring simultaneously may impact severely on the biological functions necessary to maintain homeostasis in sheep.

    Previous studies have determined that alpha-quartz (crystalline silica) can cause pulmonary inflammation, damage, and fibrosis. However, the temporal relationship between silica inhalation and pulmonary inflammation, damage, and fibrosis has not been fully examined. To address this gap in our knowledge of silica-induced pulmonary fibrosis, a chronic inhalation study using rats was designed. Specifically, rats were exposed to a silica aerosol (15 mg/m3 silica, 6 h/d, 5 d/wk, 116 d), and measurements of pulmonary inflammation, damage, and fibrosis were monitored throughout the study. We report (1) data demonstrating that the silica aerosol generation and exposure system produced a consistent silica aerosol of respirable size particles; (2) the time course of silica deposition in the lung; (3) calculations that demonstrate that the rats were not in pulmonary overload; (4) histopathological data demonstrating time-dependent enhancement of silica-induced alveolitis, epithelial hypertrophy and hyperplasia, alveolar lipoproteinosis, and pulmonary fibrosis in the absence of overload; and (5) biochemical data documenting the development of lipidosis, lung damage, and fibrosis.

    Metaiodobenzylguanidine (MIBG) scans are sensitive testing tools for neuroblastoma. Persistent positive MIBG scans in patients with stage 3 neuroblastoma have previously been found to indicate maturation rather than regression. We assessed the significance of this finding in stage 4 neuroblastoma in the present study. Fifteen consecutive pediatric patients with stage 4 neuroblastoma treated between 2004 and 2014 at the Kagoshima University Hospital were retrospectively examined. Treatment involved a combination of multiagent chemotherapy, resection, autologous peripheral blood stem cell transplantation (PBSCT), radiotherapy, and maintenance therapy with retinoic acid. The MIBG uptake in each patient during treatment was assessed using a Curie score. The 5-year event-free and overall survival rates in 15 patients were 38.9% and 58.7%, respectively. Four patients with persistent positive MIBG scans who underwent autologous PBSCT but experienced decreased 123 I-MIBG uptake during the clinical course survived without progression, and their event-free survival (EFS) was significantly superior to that of patients who showed negative MIBG scans after PBSCT (5-year EFS rate: 18.2%, p = 0.0176). Therefore, persistent positive MIBG scans with gradually decreased uptake after PBSCT do not always indicate neuroblastoma progression, and may instead indicate tumor maturation in some selected cases, if not all cases, of stage 4 neuroblastoma.

    Blood culture (BC) is the gold standard when a bacteraemia is suspected, and is one of the most requested microbiological tests in paediatrics. Some changes have occurred in recent years: the introduction of new vaccines, the increasing number of patients with central vascular catheters, as well as the introduction of continuous monitoring BC systems. These changes have led to the review and update of different factors related to this technique in order to optimise its use. A practice guideline is presented with recommendations on BC, established by the Spanish Society of Paediatric Emergency Care and the Spanish Society for Paediatric Infectious Diseases. After reviewing the available scientific evidence, several recommendations for each of the following aspects are presented: BC indications in the Emergency Department, how to obtain, transport and process cultures, special situations (indications and interpretation of results in immunosuppressed patients and/or central vascular catheter carriers, indications for anaerobic BC), differentiation between bacteraemia and contamination when a BC shows bacterial growth and actions to take with a positive BC in patients with fever of unknown origin.

    Full Text Available The aim of the study – determining of changes in peripheral blood (PB in patients with secondary erythrocytosis (SE and polycythemia vera (PV, detection of discriminatory parameters levels of PB indicators and analyzing of their operating characteristics for differentiation of erythrocytosis and predicting of thrombotic events in patients with PV. Materials and methods. The material for the study was the results of clinical trials of 210 patients with erythrocytosis who underwent differential diagnosis between PV and SE. Results and discussion. The optimal threshold for differential diagnosis of red blood cells content between PV and SE is >6.08•1012/ L, the diagnostic value of the marker equals to the level of a good diagnostic marker (AUC=0.82; 95% CI=0.77-0.87, p 57.5% with its capacity – 0.72 (0.66-0.78, p 8.9•109/L, and the boundary of marker is consistent with a good level of efficiency (AUC=0.79, 95% CI=0.72-0.84, p287•109 /L" to differentiate erythrocytosis is 0.90 (0.86-0.94, p 55%" and "WBC >12.3•109 /L", according to the AUC (AUC=0.65; 95% CI=0.52-0.79, p=0.021 and AUC=0.66; 95% CI=0.55-0.77, p=0.003, respectively, corresponds to the average power level. Conclusion. Hemoglobin has not confirmed its value for the differential diagnosis between PV and SE. Using other parameters of PB with the aim of differentiating PV and SE is rational, but their discriminatory power levels greatly depend on the group erythrocytosis. In our cohort were obtained the following most appropriate criteria for inclusion of patients in the group of patients with PV: "WBC >8.9•109/L", "red blood cells >6.08•1012/L" and "hematocrit >57.5%". The most significant marker of general clinical blood test to differentiate between PV and SE is "platelets >287•109/L". Hematocrit over 55% and WBC over 12.3•109/L are valuable prognostic markers of thrombosis in PV patients, but their use is appropriate only in a cohort of patients with PV without

    Full Text Available Background and purpose: Approximately one-third of the world's population suffers from anemia. Anemia in adults causes irritability, impaired mental focus, difficulty in daily activities, and sleep. Body mass index (BMI is an indicator of nutritional status in adults. The current study aimed to assess the body mass index and blood indices of students in local domain. Materials and methods:   This cross-sectional study was performed on the students of Babol University of Medical Sciences. BMI value was obtained based on weight and height for each case.  Cell blood count was also carried out for each participant. Hemoglobin of less than 12 g/dl and 13g/dl were considered as anemia in females and males, respectively. Results: Of 312 sample students, 212 cases were female and 100 were male. The average BMI and hemoglobin were 22.8 kg/m2 and 14 g/dl, respectively. Fifty-five (17.6% students were anemic. Also, the analysis of distribution of BMI measurement by gender showed that being underweight was more prevalent in females (9.4% in comparison with males (5%. The highest prevalence rate of anemia was observed in the cases that had BMI ≥ 25. Overall, not any significant statistical difference was observed between BMI and anemia. Conclusion: With regard to the results, overweight and obesity were associated with a lower probability of anemia in students. It was also revealed that anemia and emaciation, mainly observed in female students, should be considered as major issues for health care system. Thus, public health intervention was suggested to be performed so as to prevent combined micronutrient deficiencies and obesity. An investigation of the potential causes of this phenomenon was also recommended.

    Recanalization of occluded vessels has been attempted for the treatment of acute hemispheric ischemic stroke, but increases the risk of hemorrhage. The purpose of this study is to determine the indications for recanalization therapy in acute ischemic stroke by quantitative evaluation of cerebral blood flow by SPECT. We studied retrospectively the relationship between regional cerebral blood flow (rCBF) measured by 99m Tc-HM-PAO SPECT before treatment and the radiological final outcome in 9 patients, who had hemispheric ishemic strokes and underwent successful recanalization of the occluded artery by endovascular technique within 6 hours after onset. A noninvasive method described by Matsuda et al (Patlak plot) was used for the quantitative measurement of rCBF with SPECT. The results showed that the low value of rCBF before treatment correlated with the development of infarction after recanalization. When recanalization was achieved between 2 and 6 hours after onset, the critical level of rCBF to develop infarction was 25-30 ml/100 g/min. Despite early recanalization, one patient with a significant rCBF defect suffered from hemorrhagic transformation after recanalization. The measurement of rCBF by 99m Tc-HM-PAO SPECT is available for emergent cases and is very useful to determine the extent and the degree of ischemic insult in acute ischemic strokes. Our data indicate that if the residual rCBF, measured by SPECT, is over 25 ml/100 g/min, emergent recanalization therapy should be considered, while on the other hand, if the residual rCBF is severely reduced (below 20 ml/100 g/min), acute recanalization is contraindicated to avoid fatal hemorrhagic transformation. A prospective study to enhance our preliminary results is needed. (author)

The measurement of rCBF by {sup 99m}Tc-HM-PAO SPECT is available for emergent cases and is very useful to determine the extent and the degree of ischemic insult in acute ischemic strokes. Our data indicate that if the residual rCBF, measured by SPECT, is over 25 ml/100 g/min, emergent recanalization therapy should be considered, while on the other hand, if the residual rCBF is severely reduced (below 20 ml/100 g/min), acute recanalization is contraindicated to avoid fatal hemorrhagic transformation. A prospective study to enhance our preliminary results is needed. (author)

    Although a single-item job satisfaction measure has been shown to be reliable and inclusive as multiple-item scales in relation to health, studies including immunological data are few. The purpose of this study was to evaluate the validity of single-item job and family life satisfaction based on its association with immune indices. A total of 189 white-collar employees (70% men) underwent a blood draw for the measurement of natural killer (NK), total T, and B cell counts as well as plasma immunoglobulin (Ig) G concentrations and completed single-item job and family life satisfaction measures, respectively. The response options for satisfaction measures were 'dissatisfied' (coded 1) to 'satisfied' (coded 4). Spearman's partial correlations controlling for cofactors revealed that increased job satisfaction was positively associated with NK cells (rsp=0.201, p=0.007) and IgG (rsp=0.178, p=0.018), while family life satisfaction was unrelated to immune indices. Those who reported a combination of low job/low family life satisfaction had significantly lower NK and higher B cell counts than those with a high job/high family life satisfaction. Our study suggests that the single-item summary measure of job satisfaction, but not family life satisfaction, may be a valid tool to evaluate immune status in healthy white-collar employees.

    Maximum home systolic blood pressure has been shown to predict target organ damage. We aimed to clarify the association between maximum home systolic blood pressure and urine albumin to creatinine ratio, an indicator of early-phase diabetic nephropathy in patients with type 2 diabetes. In 1040 patients, we assessed the relationship of mean or maximum home systolic blood pressure and urine albumin to creatinine ratio, and compared the area under the receiver operating characteristic curve of mean or maximum home systolic blood pressure for diabetic nephropathy (urine albumin to creatinine ratio ⩾30 mg/g Cr). Multivariate linear regression analyses indicated that mean morning systolic blood pressure ( β = 0.010, p blood pressure ( β = 0.008, p blood pressure was 0.667 (0.634-0.700; p blood pressure, as well as mean home systolic blood pressure, was significantly associated with diabetic nephropathy in patients with type 2 diabetes.

    Effect of long-term oral administration of three different concentrations (0.5, 1.0, and 2.0%) of micronized β-1.3/1.6-D-glucan derived from oyster mushroom (Pleurotus ostreatus, Hiratake) on biometrical, haematological, biochemical, and immunological indices of half-year-old rainbow trout (Oncorhynchus mykiss) was assessed in the study. Rainbow trout were feed commercial feed pellets containing β-1.3/1.6-D-glucan in the concentrations of 0.5, 1.0, and 2.0% for 85 days. Biometrical indices consisted in total and standard length, body and liver weight, from which derived somatic parameters such as Fulton´s condition factor and hepatosomatic index were calculated. Haematological parameters were evaluated according to unified methods for haematological examination in fish. Plasma biochemical profile was analysed using biochemical analyser Konelab 20i and Easy Lyte Analyzer. A phagocyte cells metabolic activity (induced chemiluminescence of phagocytes) was determined as an immunological parameter by a microplate luminometric method on Immunotech LM-01T. No clinical signs of behavioral, respiratory, or neurologic distress were observed in rainbow trout. Fish showed normal feeding behavior. As for biometric parameters, no significant changes in total and standard length, body weight, liver weight, as well as in condition factor and hepatosomatic index of experimental and control fish were found. In the course of the study, weight gains in rainbow trout were similar and continuous. Shifts in PCV (prainbow trout was not altered by oyster mushroom β-1.3/1.6-D-glucan administration. After long-term oral administration of three concentrations of micronized β-1.3/1.6-D-glucan derived from oyster mushroom (Pleurotus ostreatus, Hiratake) shifts in haematological and biochemical profiling were found in half-year-old rainbow trout (O. mykiss) in environmental conditions of a commercial rainbow trout fishery. Biometrical indices were not found significantly altered. No

    Full Text Available The aim of this study was to determine the effect of changes in body condition in the dry period and the early lactation period on the incidence of retained placenta and ketosis in 94 high-yielding Holstein-Friesian cows. Body condition scoring was performed every two weeks from the beginning of the dry period until week 18 of lactation. Blood for the measuring of indicators of metabolism was sampled in weeks 1 and 2 ante partum and in weeks 1, 2, 3, 7 and 15 post partum. Retained placenta was reported in 11 cows, and ketosis was diagnosed in 18 animals. One week ante partum, the serum profile of cows diagnosed with ketosis during lactation revealed 0.52 mmol/l β-hydroxybutyric acid and 0.29 mmol/l non-esterified fatty acids on average. One week post partum, the serum profile of cows with ketosis revealed 1.59 mmol/l β-hydroxybutyric acid and 1.09 mmol/l non-esterified fatty acids and cows with retained placenta 1.65 and 1.41, respectively. From the week 5 ante partum to the point of lowest body condition the average body condition loss reached 1.4 points in cows with retained placenta, 1.1 points in cows with ketosis, and 0.8 points in healthy cows. Retained placenta and ketosis increased significantly conception rates by 0.47 and 0.50, respectively. Our results show that monitoring changes in the body condition and non-esterified fatty acids and β-hydroxybutyric acid blood levels in high-yielding cows in the transition period, followed by taking relevant disease-control measures, may be effective in reducing the incidence of retained placenta and ketosis in dairy cattle herds.

    Individual responses to hemorrhage vary, with varying periods of compensation before the development of shock. We characterized heart rate and blood pressure variability measures during hemorrhage of 25 mL/kgBody Weight for 15 min in conscious sheep (N = 7, 14 total hemorrhages) as markers of the transition from compensated to decompensated shock using the continuous wavelet transform. Heart rate-low frequency (HR-LF) and systolic blood pressure-low frequency (SBP-LF) indices were developed to represent the change in spectral power during hemorrhage as low-frequency (0.06 - 0.15 Hz) power divided by the sum of high (0.15 - 1.0 Hz)- and very low (0.02 - 0.06 Hz) frequency power. Heart rate rose from 96.3 (22.2) beats/min (mean [SD] across all trials) to a peak of 176.0 (25.4) beats/min occurring at a minimum time of 5.3 min to a maximum of 22.1 min (11.7 [1.6] min), depending on the trial, after the start of hemorrhage. During the HR-compensated response to hemorrhage, there was elevated HR-LF and SBP-LF in five of the seven animals. In these animals, HR-LF and SBP-LF dropped to below baseline levels around the time of the peak HR. The results from this conscious-animal study suggest that HR and SBP low-frequency power rise during the compensation phase of the response to hemorrhage in conscious sheep. Use of variability monitoring could aid in describing an individual's current response to hemorrhage and anticipation of impending decompensation; however, individual differences in the response limit this potential.

    Full Text Available The aim of the study was to determine the effect of a phytogenic additive on blood serum indicator levels and fatty acids profile of breast, leg muscles and liver in fattening turkeys. The experiment was realized in private turkey farm and in the Department of Animal Nutrition, Faculty of Agrobiology and Food Resources, Slovak University of Agriculture in Nitra. A total of 300 clinically healthy female turkeys (broad-breasted white turkey, hybrid XL were used in the experiment. Female turkeys were randomly divided into two groups (150 pcs per each. In the control group, turkey were fed with standard complete feed mixtures for fattening, in the experimental group, standard diets from the beginning to 12th week were supplemented with the a blend of essential oils from origanum, anise and citrus fruits as well as a prebiotic rich fructooligosaccharides in dosage 1kg per 1000 kg of feed mixture. Fattening lasted 18 weeks. Blood serum was collected at the end of the experiment, during the slaughter of birds. Samples of breast and leg muscles, and liver for fatty acids composition evaluation were collected during birds dissection (10 samples per each group. After the 12 weeks of phytoadditive supplementation, a tendency of lower activity of serum alanine aminotransferase (53.963 vs. 3.499 U/L and aspartate aminotransferase (6.238 vs. 1.012 U/L in experimental group of turkeys was found (P0.01 content of cis-8,11,14-eicosadienoic and arachidonic acids. The phytoadditive supplementation significantly (P<0.01 decreased content of some unsaturated fatty acids in turkeys tissues, as well. In experimental group of turkey have been recorded lower level of elaidic and oleic acids in the breast muscle and cis-11,14-eicosadienoic and arachidonic acids in the liver, compare to birds from control group.

    Full Text Available Objective: To explore the effect of atorvastatin calcium on the carotid atherosclerotic plaque, serum lipid level, and cerebral hemodynamic indicators in patients with transient ischemic attack (TIA. Methods: A total of 80 patients with TIA and carotid atherosclerotic plaque who were admitted in our hospital and confirmed by the ultrasound were included in the study and randomized into the treatment group and the control group (n = 40. The patients in the two groups were given TIA routine treatments and aspirin. On this basis, the patients in the treatment group were given atorvastatin calcium. The carotid ultrasound before treatment and 6 months after treatment in the two groups was performed to compare the atherosclerotic plaque area and IMT. The serum lipid level and cerebral hemodynamic parameters were detected. Results: IMT and carotid plaque area after treatment in the treatment group were significantly reduced when compared with before treatment (P0.05. TC, TG, and LDL levels after treatment were significantly reduced when compared with before treatment (P<0.05, while HDL level was significantly elevated when compared with before treatment (P<0.05. TC, TG, and LDL levels after treatment in the treatment group were significantly lower than those in the control group (P<0.05, while HDL level was significantly higher than that in the control group (P<0.05. The average blood velocity and average blood flow volume of cerebral circulation after treatment in the treatment group were significantly higher than those in the control group (P<0.05, while the cerebrovascular characteristic resistance and peripheral resistance were significantly lower than those in the control group (P<0.05. Conclusions: Atorvastatin calcium in the treatment of TIA can significantly reduce the serum lipid level, alleviate or stabilize the carotid atherosclerotic

    Full Text Available Exercise is beneficial for a variety of age-related disorders. However, the molecular mechanisms mediating the beneficial adaptations to exercise in older adults are not well understood. The aim of the current study was to utilize a dual approach to characterize the genetic and metabolic adaptive pathways altered by exercise in veteran athletes and age-matched untrained individuals. Two groups of 50-60 year old males: competitive cyclists (athletes, n = 9; VO2peak 59.1±5.2 ml·kg(-1·min(-1; peak aerobic power 383±39 W and untrained, minimally active individuals (controls, n = 8; VO2peak 35.9±9.7 ml·kg(-1·min(-1; peak aerobic power 230±57 W were examined. All participants completed an acute bout of submaximal endurance exercise, and blood and urine samples pre- and post-exercise were analyzed for gene expression and metabolic changes utilizing genome-wide DNA microarray analysis and NMR spectroscopy-based metabolomics, respectively. Our results indicate distinct differences in gene and metabolite expression involving energy metabolism, lipids, insulin signaling and cardiovascular function between the two groups. These findings may lead to new insights into beneficial signaling pathways of healthy aging and help identify surrogate markers for monitoring exercise and training load.

    It has been suggested that coffee may affect the gut-brain axis with conflicting outcomes. Moreover, there is insufficient evidence to determine whether the type or temperature of coffee consumed will have a different impact on the gut-brain axis. The purpose of this study was to investigate the effects of acute coffee consumption on the following: 1. self-reported GI symptoms and salivary gastrin, 2. stress indices [salivary cortisol and alpha-amylase (sAA)] and psychometric measures, and 3. blood pressure (BP), in healthy, daily coffee consuming individuals in non-stressful conditions. This was a randomized, double blind, crossover clinical trial, in which 40 healthy individuals (20 men, 20 women), 20-55 years of age, randomly consumed four 200 ml coffee beverages containing 160 mg caffeine (hot and cold instant coffee, cold espresso, hot filtered coffee), 1 week apart. Salivary samples and psychometric questionnaires were collected at baseline and post-coffee consumption at 15,30, and 60 min for salivary gastrin and sAA measurements and at 60,120, and 180 min for cortisol measurements. BP was measured at beginning and end of each intervention. ClinicalTrials.gov ID: NCT02253628 RESULTS: Coffee consumption significantly increased sAA activity (P = 0.041), with significant differences only between cold instant and filter coffee at 15 and 30 min post-consumption (P Coffee temporarily increased salivary gastrin, without differences between coffee types. Coffee did not affect salivary cortisol or self-reported anxiety levels. Coffee consumption significantly increased BP, within the healthy physiological levels, in a gender specific manner at the end of the experimental periods, without differences between coffee types. Acute coffee consumption in non-stressful conditions activated sAA and BP but not salivary cortisol, indicating activation of the sympathetic nervous system. Post-coffee sAA increase without a concomitant cortisol increase may also indicate that

    This study aimed to describe chronological patterns of changes of various candidate blood components in milk during the acute phase of a mammary immune response in detail. Eight dairy cows were challenged with Escherichia coli lipopolysaccharide in one udder quarter. Milk from challenged and control quarters and blood samples were taken before, and 1 and 2 h after challenge and then every 15 min until 5 h after challenge. The SCC, serum albumin, immunoglobulin (Ig)G1, IgG2, lactate dehydrogenase (LDH), and L-lactate in milk and blood, and α-lactalbumin in blood were analysed. All selected parameters in milk increased in challenged quarters but did not increase in control quarters. Milk IgG1, IgG2, serum albumin, and LDH were already significantly increased at 2 h after challenge whereas a significant increase of SCC was detectable at 2.75 h and L-lactate was increased at 2.25 h after challenge. In blood L-lactate was increased at 3.75 h after challenge, however, other factors in blood did not change significantly within the 5 h of experiment. In conclusion, the increase of blood components in milk during inflammation follows two different patterns: There is a rapid increase for IgG1, IgG2, or LDH, before the increase of SCC, and their concentrations reach a plateau within 3 h. On the other hand, SCC and L-lactate show a slower but consistent increase not reaching a plateau within 5 h after LPS challenge. L-lactate increases to higher concentrations in milk than in blood. This clearly shows that the increase of blood components follows different patterns and is therefore a controlled and compound-specific process and not exclusively an unspecific type of leakage.

    High 24-h ambulatory blood pressure (ABP) variability is associated with poor cardiovascular outcomes. We analysed a large ABP monitoring database containing data from hypertensive patients treated with telmisartan\\/amlodipine combination or various monotherapies with the aim of quantifying the 24-h distribution of blood pressure (BP) reduction by treatment through the smoothness index and of developing and testing a new treatment-on-variability index (TOVI) to quantify the effects of treatment on both mean BP and BP variability.

    This study was conducted to explore the association of eating frequency (EF) with anthropometric indices and blood pressure (BP) in children and adolescents. This nationwide cross-sectional study was performed on a multi-stage sample of 14,880 students, aged 6-18 years, living in 30 provinces in Iran. Parents were asked to report dietary intake of children as frequency of food groups and/or items. EF was defined as the sum of the daily consumption frequency of main meals and snacks. Association of EF with weight disorders, abdominal obesity, and elevated BP was assessed using different logistic regression models adjusted for potential confounding factors. Eating more frequently (≥ 6 vs. ≤ 3) was found among students who were at younger age (11.91 vs. 13.29 years) (pobese compared to those who had EF ≤ 3. Having EF of 4 (OR: 0.82, CI: 0.71-0.94), 5 (OR: 0.86, CI: 0.74-0.99), and ≥ 6 (OR: 0.73, CI: 0.63-0.85) was related to lower prevalence of abdominal adiposity. Higher EF was associated with lower mean values of anthropometric and BP measures, as well as with lower prevalence of generalized and abdominal obesity in children and adolescents. Longitudinal studies are needed to assess the long-term effects of EF on body composition in the pediatric age group. Copyright © 2016 Sociedade Brasileira de Pediatria.

    This study analyzes pre-Katrina variation in aggregate student performance and children's blood lead (BPb) in 117 elementary school districts in metropolitan New Orleans. Fourth grade student achievement on Louisiana Educational Assessment Program (LEAP) tests were analyzed as a function of BPb for children 1-6 years old within school districts, controlling for student-teacher ratios, percent of students eligible for a free or discounted lunch, and school racial demography. Measures of performance across subject areas (English Language Arts, Science, Mathematics, and Social Studies) include school Achievement Test Scores (ATS) and indices of agreement and variation in student achievement. ATS are measured on a 5-point scale, corresponding to achievement categories of advanced=5 to unsatisfactory=1. Regression results show that median BPb (microg/dL) and percent of children with BPb > or =10 microg/dL are significantly associated with reductions in test scores across all subjects and depress variation in student performance across achievement categories. These data suggest that assisting children with improved school performance requires alleviation of pre-school Pb exposure and its associated neurotoxic damage. Cost-benefit calculations suggest that it is more cost effective to pay for onetime primary prevention instead of paying continuous expenses focused on reversing neurotoxic damage.

  7. Comparison between visual half-field performance and cerebral blood flow changes as indicators of language dominance.

    The determination of hemispheric language dominance (HLD) can be accomplished in two ways. One approach relies on hemispheric differences in cerebral blood flow velocity (CBFV) changes during language activity, while the other approach makes use of performance differences between the left and right visual field when verbal stimuli are presented in a tachistoscopic visual field paradigm. Since both methodologically different approaches claim to assess functional HLD, it seems plausible to expect that the respective laterality indices (LI) would correspond. To test this expectation we measured language lateralisation in 58 healthy right-handed, left-handed, and ambidextrous subjects with both approaches. CBFV changes were recorded with functional transcranial Doppler sonography (fTCD). We applied a lexical decision task with bilateral visual field presentation of abstract nouns and, in addition, a task of mental word generation. In the lexical decision task, a highly significant right visual field advantage was observed for number of correct responses and reaction times, while at the same time and contrary to expectation the increase of CBFV was significantly higher in the right than left hemisphere. During mental word generation, the acceleration of CBF was significantly higher in the left hemisphere. A comparison between individual LI derived from CBF measurement during mental word generation and from visual field performances in the lexical decision task showed a moderate correspondence in classifying the subjects' HLD. However, the correlation between the corresponding individual LI was surprisingly low and not significant. The results are discussed with regard to the issue of a limited reliability of behavioural LI on the one hand and the possibility of a fundamental difference between the behavioural and the physiological indicators of laterality on the other hand.

    High blood pressure is strongly associated with obesity in different populations. However, it is unclear whether different anthropometric indicators of obesity can satisfactorily predict high blood pressure in the school setting. This study evaluated the sensitivity and specificity of body mass index, waist circumference, and waist to height ratio in the detection of high blood pressure in adolescents. The sample consisted of 8295 adolescents aged 10-17 years. Weight was measured using a digital scale, height with a stadiometer, and waist circumference using a tape measure. Blood pressure was measured by an automatic blood pressure measuring device. ROC curves were used for the analysis of sensitivity and specificity of the three anthropometric indices in identifying high blood pressure. Binary Logistic Regression was used to assess the association of body mass index, waist circumference, and waist to height ratio with high blood pressure. Low values of sensitivity were observed for body mass index (0.35), waist circumference (0.37), and waist to height ratio (0.31) and high values of specificity for body mass index (0.86), waist circumference (0.82), and waist to height ratio (0.83) in the detection of high blood pressure. An association was observed between adolescents classified with high body mass index (OR=3.57 [95% CI=3.10-4.10]), waist cirumference (OR=3.24 [95% CI=2.83-3.72]), and waist to height ratio (OR=2.94 [95% CI=2.54-3.40]) with high blood pressure. Body mass index, waist circumference, and waist to height ratio presented low sensitivity to identify adolescents with high blood pressure. However, adolescents classified with high body mass index, waist circumference, and waist to height ratio demonstrated a high association of presenting high blood pressure.

    Not only the nutritional status and biological activity but also the soil ecological functioning or soil health has been impacted profoundly by land degradation in the karst area of southwest China where the karst ecosystems are generally considered as extremely vulnerable to land degradation under intensified land-use changes. The objectives of this study are to elucidate the changes in overall soil quality by a holistic approach of soil nutritional, biological activity, and soil health indicators in the karst area as impacted by intense cultivation and vegetation degradation. Topsoil samples were collected on selected eco-tesserae in a sequence of land degradation in a karst area of southwest Guizhou in 2004. The soil nutrient pools of organic carbon (Corg), extractable extracellular carbon (Cext), total soil nitrogen (Nt), alkali-hydrolyzable nitrogen (Nah), total phosphorus (Pt), available phosphorus (Pa) were analyzed by wet soil chemistry. The soil biological properties were studied by means of measurements of microbial biomass carbon (both by fumigation-extraction, FE-Cmic, and by calculation from substrate-incubation respiration, SIR-Cmic) of respiration [respiration without addition of substrates, basal respiration (BR), and potential respiration (PR) with substrate-incubation] and of soil enzyme activities (invertase, urease, and alkaline phosphatase). Soil health status was assessed by simple indices of Cmic/Corg and BR/Cmic in conjunction with bacterial community structures determined by polymerase chain reaction and denaturing gradient gel electrophoresis. While the nutritional pool parameters, such as Corg and Cext, described basically the changes in soil life-supporting capacity with cultivation interference and vegetation declined, those parameters of biological activity such as FE-Cmic, SIR, and SIR-Cmic as well as bacterial community structures measured by molecular method evidenced well the changes in soil functioning for ecosystem health with

    Full Text Available Research and development of health science require an animal model which has been known for itsorigin and characteristics. One of experimental animal model which is commonly used is albino rat. Thepurpose of this study was to investigate weight of organs (kidney, liver, spleen, and lung, hematologicalvalues (hemoglobin, hematocrit, erythrocyte and leucocyte, and the values of the biochemical blood (SGPT,SGOT, glucose and total protein of the albino rat at different ages. This study used 60 rats, which weredivided into 3 groups based on age namely 1, 2, and 3 months and groups based on sex that each groupconsisted of 10 males and 10 females. Samples of age and sex groups of rat were taken randomly. Eachcage consisted of 5 rats with the same ages and sex. Those rats fed and tap water ad libitum. The rats weresacrificed anaesthetically by with ether to take their blood and measure their organ‘s weight. Data wasanalyzed using one way ANOVA test, except data from heart organ which was analyzed using nonparametrictest (Friedman Test. To find out the increase of rats body weight age 1 -3 months, it was usedregression linier test.

    Full Text Available The objective of this study was to assess the effects of the season, travel duration and trailer compartment location on blood creatine-kinase (CK, lactate and cortisol concentrations in 384 pigs and assess their relationships with trailer temperature, heart rate and gastrointestinal tract temperature (GTT, behavior, carcass damage scores and meat quality. Blood CK was greater in pigs transported in summer (p = 0.02, after 18 h transportation (p < 0.001 and in pigs located in C4, C5 and C10 (p = 0.002. In winter, the concentration of blood lactate was higher (p = 0.04 in pigs transported for 6 h in C5. Pigs located in C10 showed higher (p = 0.01 concentration of cortisol than those transported for 18h in C4 in summer. The highest correlations were between blood cortisol and GTT (r = 0.53; p < 0.001, and between blood CK and GTT (r = 0.41; p < 0.001, truck temperature (r = 0.42; p < 0.001, and pHu in the longissimus muscle (r = 0.41; p < 0.001. In conclusion, although increased blood cortisol and CK levels appear to indicate a physical stress condition in transported pigs, the weak to moderate correlations with environmental and other animal welfare indicators suggest that blood stress parameters can only be used as a complementary measurement in the assessment of the pigs’ response to transport stress.

    Full Text Available Abstract Objectives: This study was conducted to explore the association of eating frequency (EF with anthropometric indices and blood pressure (BP in children and adolescents. Methods: This nationwide cross-sectional study was performed on a multi-stage sample of 14,880 students, aged 6–18 years, living in 30 provinces in Iran. Parents were asked to report dietary intake of children as frequency of food groups and/or items. EF was defined as the sum of the daily consumption frequency of main meals and snacks. Association of EF with weight disorders, abdominal obesity, and elevated BP was assessed using different logistic regression models adjusted for potential confounding factors. Results: Eating more frequently (≥6 vs. ≤3 was found among students who were at younger age (11.91 vs. 13.29 years (p < 0.001. Students who reported an EF of 4 (OR: 0.67, CI: 0.57–0.79, 5 (OR: 0.74, CI: 0.62–0.87, and 6 (OR: 0.54, CI: 0.44–0.65 had lower odds of being obese compared to those who had EF ≤ 3. Having EF of 4 (OR: 0.82, CI: 0.71–0.94, 5 (OR: 0.86, CI: 0.74–0.99, and ≥6 (OR: 0.73, CI: 0.63–0.85 was related to lower prevalence of abdominal adiposity. Conclusion: Higher EF was associated with lower mean values of anthropometric and BP measures, as well as with lower prevalence of generalized and abdominal obesity in children and adolescents. Longitudinal studies are needed to assess the long-term effects of EF on body composition in the pediatric age group.

  16. Aspects on the Physiological and Biochemical Foundations of Neurocritical Care

    Carl-Henrik Nordström

    2017-06-01

    Full Text Available Neurocritical care (NCC is a branch of intensive care medicine characterized by specific physiological and biochemical monitoring techniques necessary for identifying cerebral adverse events and for evaluating specific therapies. Information is primarily obtained from physiological variables related to intracranial pressure (ICP and cerebral blood flow (CBF and from physiological and biochemical variables related to cerebral energy metabolism. Non-surgical therapies developed for treating increased ICP are based on knowledge regarding transport of water across the intact and injured blood–brain barrier (BBB and the regulation of CBF. Brain volume is strictly controlled as the BBB permeability to crystalloids is very low restricting net transport of water across the capillary wall. Cerebral pressure autoregulation prevents changes in intracranial blood volume and intracapillary hydrostatic pressure at variations in arterial blood pressure. Information regarding cerebral oxidative metabolism is obtained from measurements of brain tissue oxygen tension (PbtO2 and biochemical data obtained from intracerebral microdialysis. As interstitial lactate/pyruvate (LP ratio instantaneously reflects shifts in intracellular cytoplasmatic redox state, it is an important indicator of compromised cerebral oxidative metabolism. The combined information obtained from PbtO2, LP ratio, and the pattern of biochemical variables reveals whether impaired oxidative metabolism is due to insufficient perfusion (ischemia or mitochondrial dysfunction. Intracerebral microdialysis and PbtO2 give information from a very small volume of tissue. Accordingly, clinical interpretation of the data must be based on information of the probe location in relation to focal brain damage. Attempts to evaluate global cerebral energy state from microdialysis of intraventricular fluid and from the LP ratio of the draining venous blood have recently been presented. To be of clinical relevance

    The endothelium-specific antigen PAL-E is expressed in capillaries and veins throughout the body with the exception of the brain, where the antigen is absent from anatomical sites with a patent blood-brain barrier. In this study we determined vascular endothelial staining for PAL-E in the normal eye in relation to the ocular blood-tissue barriers. Immunohistochemical staining of frozen tissue sections of eyes from 22 cornea donors and a number of normal animal autopsy eyes was performed for the PAL-E antigen and the blood-brain barrier marker glucose transporter 1. In normal human and animal eyes, endothelial PAL-E staining was absent from the microvasculature in iris, ciliary muscle, optic nerve and retina. In a few normal human eyes, some weakly stained capillaries were observed in the retina and nerve fiber layer, mostly in the peripapillary area. Marked staining of capillaries and venules with PAL-E was observed in the conjunctiva, episclera, sclera, ciliary processes, choriocapillaris and optic nerve head. In general, the endothelial antigen PAL-E is absent from microvessels involved in the blood-ocular and the blood-retinal barriers. PAL-E may therefore be a useful marker to identify pathological breakdown of blood-ocular barriers.

    The effectiveness of several non-lethal techniques as indicators of total lipid content in smallmouth bass Micropterus dolomieu, walleye Sander vitreus and channel catfish Ictalurus punctatus was investigated. The techniques included (1) the Fulton and relative condition factors, (2) relative mass, (3) plasma indicators of nutritional status (alkaline phosphatase, calcium, cholesterol, protein, triglycerides and glucose) and (4) readings from a hand-held, microwave energy meter. Although simple linear regression analysis showed that lipid content was significantly correlated with several predictor variables in each species, the r2 values for the relations ranged from 0·17 to 0·50 and no single approach was consistent for all species. Only one model, between energy-meter readings and lipid content in I. punctatus, had an r2 value (0·83) high enough to justify using it as a predictive tool. Results indicate that no single variable was an accurate and reliable indicator of whole body lipid content in these fishes, except the energy meter for I. punctatus.

    Cardiovascular events associated with energy drink consumption have been reported, but few data exist to delineate the hemodynamic effects of energy drinks. To compare the effects of an energy drink versus caffeine supplementation on blood pressure (BP) indices as measured by 24-hour ambulatory BP monitoring (ABPM). Healthy, nonsmoking, normotensive volunteers (aged 18-45 years) taking no medications were enrolled in a single-center, open-label, 2-period crossover pilot study. During each study period, subjects received either an energy drink (Red Bull Energy Drink, each dose containing 80 mg of caffeine and 1000 mg of taurine in an 8.3-oz serving) or a control (compounded caffeine solution, each dose containing 80 mg of caffeine solution in 8 oz of bottled water) at 0800, 1100, 1500, and 1900 hours and underwent 24-hour ABPM. The study periods were separated by a washout period (4-30 days). Mean 24-hour, daytime, and nighttime systolic (SBP), diastolic (DBP), and mean arterial (MAP) BP; BP load; and percent nocturnal dipping were compared between study periods. Nine subjects (5 females, mean [SD] age 27.7 [5.0] years) completed the study. Mean 24-hour SBP (123.2 vs 117.4 mm Hg, p = 0.04), DBP (73.6 vs 68.2 mm Hg, p = 0.02), and MAP (90.1 vs 84.8 mm Hg, p = 0.03) were significantly higher during energy drink supplementation versus caffeine supplementation. Daytime DBP (77.0 vs 72.0 mm Hg, p = 0.04) also was significantly higher with the energy drink versus caffeine supplementation. Trends in higher daytime SBP (127.0 vs 121.9 mm Hg, p = 0.05) and MAP (93.6 vs 88.6 mm Hg, p = 0.05) were recorded with energy drink supplementation versus caffeine supplementation. Nighttime SBP and DBP loads were significantly higher with the energy drink, but nocturnal dipping did not differ significantly between study periods. Single-day energy drink supplementation increased mean 24-hour and daytime BP compared to caffeine control in this pilot study. Additional research is

    Full Text Available The aim of this study was to investigate the protective effects of vitamin C against lead toxicity by measuring the blood parameters and studying histopathology of testis in diabetic male rats. Wister rats (42 were randomly assigned into7 groups: I healthy; II fed lead acetate only; III vitamin C administered only; IV diabetic; V diabetic rats administered by vitamin C; VI diabetic rats given lead acetate and VII diabetic rats received lead acetate and vitamin C. The diabetic and lead groups had higher glucose, cholesterol, LDL, triglycerides and lower insulin and HDL concentration than the control group. It was found that vitamin C administration led to a lower level of blood glucose, cholesterol, LDL and triglycerides and higher HDL concentration in diabetic rats significantly. It was concluded that the antioxidant property of vitamin C resulted in reducing the oxidative stress complications of toxic levels of lead acetate in diabetic rats.

    Dendritic cells (DCs) isolated from tumor bearing animals or from individuals with solid tumors display functional abnormalities and the DC impairment has emerged as one mechanism for tumor evasion from the control of the immune system. Ductal pancreatic adenocarcinoma (PDAC), the most common pancreatic cancer, is recognized as a very aggressive cancer type with a mortality that almost matches the rate of incidence. We examined the systemic influence ductal pancreatic adenocarcinoma (PDAC) exerted on levels of peripheral blood DCs and inflammatory mediators in comparison to the effects exerted by other pancreatic tumors, chronic pancreatitis, and age-matched controls. All groups examined, including PDAC, had decreased levels of myeloid DCs (MDC) and plasmacytoid DCs (PDC) and enhanced apoptosis in these cells as compared to controls. We found elevated levels of PGE2 and CXCL8 in subjects with PDAC, and chronic pancreatitis. Levels of these inflammatory factors were in part restored in PDAC after tumor resection, whereas the levels of DCs were impaired in the majority of these patients ~12 weeks after tumor removal. Our results prove that solid pancreatic tumors, including PDAC, systemically affect blood DCs. The impairments do not seem to be tumor-specific, since similar results were obtained in subjects with chronic pancreatitis. Furthermore, we found that PDAC patients with a survival over 2 years had significant higher levels of blood DCs compared to patients with less than one year survival. Our findings points to the involvement of inflammation in the destruction of the blood MDCs and PDCs. Furthermore, the preservation of the blood DCs compartment in PDAC patients seems to benefit their ability to control the disease and survival

Material and methods. There had been examined 120 patients with a lumbar and sacral dorsopathy aged from 22 to 69 years (middle age of 49,5 years with prescription of a disease from 1 to 5 years, among them men of 34,2%, women of 65,8%. Results. The analysis of effects of various medical methods on a condition of local blood circulation in the bottom extremities showed that the most expressed its compensation is noted at complex application of mechanical pulse traction influence and electrotherapy for patients with a dorsopathy of lumbar and sacral department of a backbone that is confirmed by restoration to normal values of all indicators rheovasogramm. Conclusion. High clinical results of application of the combined medical and rehabilitation complex are based on compensation of local blood circulation that is shown in elimination of deficiency of blood supply due to improvement of a tone of arterial vessels and elimination of venous stagnation, and also due to increase of linear speed of a blood-groove and development of collateral blood circulation. Application of electrical impulse and mechanical traction influences, more at their combination promotes fermentative activity of the systems responsible for a protein exchange that is important for prevention of degenerate and dystrophic process progressing.

    The fruit of Ligustrum lucidum (FLL, Nuzhenzi in Chinese) is an important traditional medicine, and have attracted significant research attention because of their various biological activities. However, there are few research reports available on the use of FLL as a feed additive in livestock nutrition, particularly in layers. This study was conducted to determine the effects of supplementation of the diet of laying hens with FLL on laying performance, egg quality and blood metabolites. A total of 360 72-week-old hens were allocated to three dietary treatments (eight replications of 15 hens/treatment group) and were fed either a control diet or a diet supplemented with an inclusion level of 0.25% or 0.50% of FLL powder in the final feed, until 78 weeks of age. Hens were housed in a three-tier cage system. Feed and water were provided ad libitum. Blood samples and eggs were collected at the end of the experiment. The results showed that dietary supplementation with FLL did not affect egg weight, feed conversion ratio, eggshell thickness, albumen height, egg yolk color, eggshell breaking strength or egg shape index. However, FLL supplementation significantly decreased (Phens fed FLL compared with the control group. It can be concluded that FLL, at a supplementation level of 0.25% final feed, can be used as an effective feed additive to improve the performance of laying hens during the late laying period.

    Full Text Available Abstract: The Study of Cardiovascular Risk in Adolescents (ERICA is a pioneering study that aimed to assess the prevalence of cardiovascular risk factors, including metabolic syndrome components in Brazilian adolescents. This study aims to describe the methodological aspects related to blood collection as well as to report pertaining results of the preparation, transport, storage, and exams in ERICA. Exams in ERICA were performed in a single laboratory and blood samples were collected in schools in a standardized manner. Logistics involved air transportation of samples to the reference laboratory with controlled temperature since sample collection. The serum was stored in local biorepositories in four centers to be used in future analyses. During the study, 284,247 exams were performed and rate of participation in exams was 56.2%, thus involving 40,732 adolescents. From the total, 92.6% of the samples reached the reference laboratory maintaining the temperature between 0-10°C. No clinical significant changes in results due to temperature changes were identified. External quality control recorded satisfactory results in 98.7% of the evaluations. Four biorepositories with samples of 7,785 adolescents were created. Thus, we can consider that the logistics adopted in ERICA was fairly successful and description of this as well as the difficulties experienced in Brazil can inform and facilitate the planning of future studies, especially in developing countries.

However, few studies have evaluated the association of RBC count with microvascular complications in patients with type 2 diabetes mellitus (T2DM. The purpose of this study was to investigate the association of RBC count with microvascular complications in patients with T2DM.Methods: This study involved 369 patients with T2DM: 243 with one or more microvascular complications and 126 without microvascular complications. Anticoagulated blood was collected and analyzed in an automated blood cell counter. The presence of risk factors for microvascular complications was determined.Results: The proportion of patients with microvascular complications increased as the RBC count decreased (P < 0.001. After adjustment for known risk factors for microvascular complications by logistic regression analysis, lower quartiles of RBC count were associated with a higher risk of microvascular complications compared with the reference group composed of the highest quartile (first quartile, odds ratio 4.98, 95% confidence interval 1.54–6.19, P = 0.008; second quartile, odds ratio 3.21, 95% confidence interval 1.17–5.28, P = 0.024.Conclusion: A decreased RBC count is associated with microvascular complications in Chinese patients with T2DM. The RBC count is a potential marker to improve further the ability to identify diabetic patients at high risk of microvascular complications.Keywords: red blood cell count, microvascular complication, type 2 diabetes

    Full Text Available The goal is to study the cerebral blood flow and psychometric characteristics in veterans of Afghanistan with early forms of chronic brain ischemia. Material and Methods. The study included 74 veterans of the Afghan war aged from 45 to 55 years: group 1, 28 people with NPNKM; Group 2-28 patients with circulatory encephalopathy stage 1; group 3-18 healthy persons. Doppler examination of cerebral vessels was carried out on the unit «Smart-lite». Reactive and personal anxiety of patients was assessed using the scale of Spielberger, evaluation of the quality of life through the test SAN. Determining the level of neuroticism and psychoticism was conducted by the scale of neuroticism and psy-choticism. Results: The study of cerebral blood flow in the Afghan war veterans showed signs of insolvency of carotid and carotid-basilar anastomoses, hypoperfusion phenomenon with the depletion of autoregulation, violation of the outflow of venous blood at the level of the microvasculature, accompanied by cerebral arteries spasm. More than 40% of patients with early forms of chronic brain ischemia had high personal anxiety, low levels of well-being and activity, with maximum expression of dyscirculatory hypoxia. Conclusion. Readaptation of veterans of Afghanistan is accompanied by the changes in psychometric performance and the formation of the earliest forms of brain chronic ischemia associated with inadequate hemodynamics providing increased functional activity of the brain and the inefficiency of compensatory-adaptive reactions.

    Ischemic placental disease is a concept that links intrauterine growth retardation (IUGR) and preeclampsia (PE) back to insufficient remodeling of uterine spiral arteries. The rheological consequences of insufficient remodeling of uterine spiral arteries were hypothesized to mediate the considerably later manifestation of obstetric disease. However, the micro-rheology in the intervillous space (IVS) cannot be examined clinically and rheological animal models of the human IVS do not exist. Thus, an in silico approach was implemented to provide in vivo inaccessible data. The morphology of a spiral artery and the inflow region of the IVS were three-dimensionally reconstructed to provide a morphological stage for the simulations. Advanced high-end supercomputing resources were used to provide blood flow simulations at high spatial resolution. Our simulations revealed turbulent blood flow (high-velocity jets and vortices) combined with elevated blood pressure in the IVS and increased wall shear stress at the villous surface in conjunction with insufficient spiral artery remodeling only. Post-hoc histological analysis of uterine veins showed evidence of increased trophoblast shedding in an IUGR placenta. Our data support that rheological alteration in the IVS is a relevant mechanism linking ischemic placental disease to altered structural integrity and function of the placenta.

    This study was conducted to investigate the effect of different supplementation levels of Chlorella microalgae on serum metabolites and the plasma content of minerals in laying hens reared under heat stress condition (27.5-36.7 °C, variable). A total number of 378 (40 weeks of age, with mean body weight of 1390 ± 120 g) were randomly allocated to six treatments with seven replicates. The birds were randomly assigned to 6 treatments (C, T1, T2, T3, T4, and T5) with 7 replicate cages of 9 birds. C. microalgae at the rates of 100, 200, 300, 400, and 500 ppm with water were offered to groups T1, T2, T3, T4, and T5, respectively, while group C served as a control. At 71 days of trial, blood samples (14 samples per treatment) were taken for measuring serum metabolites and at 72 days for plasma mineral analysis. The results of this experiment showed that the supplementation of 200-500 ppm C. microalgae decreased the serum content of cholesterol, triglycerides, and LDL ( P < 0.05) whereas HDL content increased ( P < 0.05) in the hens supplemented with C. microalgae (300 or 400 and 500 ppm). C. microalgae at rates of 300-500 ppm caused a marked ( P < 0.05) increase in the plasma content of manganese or iodine and selenium but other minerals were not statistically different among treatments. Overall, from the results of the present experiment, it can be concluded that supplementation of C. microalgae at high rates was beneficial on blood parameters of laying hens reared under heat stress.

    Tattoo pigments are deposited in the skin and known to distribute to regional lymph nodes. Tattoo pigments are small particles and may be hypothesized to reach the blood stream and become distributed to peripheral organs. This has not been studied in the past. The aim of the study was to trace tattoo pigments in internal organs in mice extensively tattooed with 2 different tattoo ink products. Three groups of mice were studied, i.e., 10 tattooed black, 10 tattooed red, and 5 untreated controls. They were tattooed on the entire back with commercial tattoo inks, black and red. Mice were sacrificed after 1 year. Samples were isolated from tattooed skin, lymph nodes, liver, spleen, kidney, and lung. Samples were examined for deposits of tattoo pigments by light microscopy and transmission electron microscopy (TEM). TEM identified intracellular tattoo pigments in the skin and in lymph nodes. TEM in both groups of tattooed mice showed tattoo pigment deposits in the Kupffer cells in the liver, which is a new observation. TEM detected no pigment in other internal organs. Light microscopy showed dense pigment in the skin and in lymph nodes but not in internal organs. The study demonstrated black and red tattoo pigment deposits in the liver; thus, tattoo pigment distributed from the tattooed skin via the blood stream to this important organ of detoxification. The finding adds a new dimension to tattoo pigment distribution in the body, i.e., as observed via the blood in addition to the lymphatic pathway. © 2017 S. Karger AG, Basel.

    Conventional semi-infinite analytical solutions of correlation diffusion equation may lead to errors when calculating blood flow index (BFI) from diffuse correlation spectroscopy (DCS) measurements in tissues with irregular geometries. Very recently, we created an algorithm integrating a Nth-order linear model of autocorrelation function with the Monte Carlo simulation of photon migrations in homogenous tissues with arbitrary geometries for extraction of BFI (i.e., αD{sub B}). The purpose of this study is to extend the capability of the Nth-order linear algorithm for extracting BFI in heterogeneous tissues with arbitrary geometries. The previous linear algorithm was modified to extract BFIs in different types of tissues simultaneously through utilizing DCS data at multiple source-detector separations. We compared the proposed linear algorithm with the semi-infinite homogenous solution in a computer model of adult head with heterogeneous tissue layers of scalp, skull, cerebrospinal fluid, and brain. To test the capability of the linear algorithm for extracting relative changes of cerebral blood flow (rCBF) in deep brain, we assigned ten levels of αD{sub B} in the brain layer with a step decrement of 10% while maintaining αD{sub B} values constant in other layers. Simulation results demonstrate the accuracy (errors < 3%) of high-order (N ≥ 5) linear algorithm in extracting BFIs in different tissue layers and rCBF in deep brain. By contrast, the semi-infinite homogenous solution resulted in substantial errors in rCBF (34.5% ≤ errors ≤ 60.2%) and BFIs in different layers. The Nth-order linear model simplifies data analysis, thus allowing for online data processing and displaying. Future study will test this linear algorithm in heterogeneous tissues with different levels of blood flow variations and noises.

    Full Text Available Background: In Brazil, listeriosis is not a notifiable disease; thus, the incidence of Brazilian cases remains unknown. Listeria monocytogenes is not always included in automated systems, and its detection depends on the high skill level of microbiology laboratory professionals. This paper describes the characteristics of L. monocytogenes isolates fortuitously obtained from an endocarditis case in Recife, PE, Brazil. Methods: Six bacterial isolates obtained from six blood cultures from a 28-year-old male bearing a prosthetic mitral heart valve were analyzed by PCR using primers specific of L. monocytogenes to confirm a presumptive identification, determine the serotype and presence of the virulence genes (inlA, inlB, inlC, inlJ, hly, plcA, actA, prfA in an attempt to determine the Listeria genotype by PCR-ribotyping. Results: The samples were identified as L. monocytogenes 4b. All investigated virulence genes were amplified by PCR, and the identity of the amplified segments was confirmed by sequencing. A deletion of 105 base pairs was detected in the actA gene. All of the samples generated the same PCR-ribotype pattern, clustered into a single ribotype, and were considered a single strain. Conclusion: L. monocytogenes infection should be considered in endocarditis differential diagnoses, especially among high-risk groups, due to its high pathogenicity and the environmental ubiquity.

    Full Text Available The objective of the work was to investigate the influence of partial substitution of magnesium oxide with natural bentonite in feed mixtures used in feeding of cows during their exposure to heat stress. The investigation lasted 30 days and was carried out during last ten days of may and first twenty days of June when average air temperature in stables was 36.6±2.5oC. In the experiment there were included 30 cows of Holstein breed in first phase of lactation, which were divided into two groups of 15 cows: control (C and experimental (E. Group C was fed with experimental mineral mixture that contained 60% of magnesium oxide during the whole investigation period. Group E was fed with experimental mineral mixture that contained 40% of magnesium oxide as well as 20% of natural bentonite. Remaining ingredients in both control and experimental mineral mixtures were the same and also contained 20% of sodium bicarbonate and 20% of zeolite in the same quantities. The control and experimental mineral mixtures were mixed into complete feed mixture (18% UP in the amount of 1%. At tne end of the investigation period, on the 30th day, there were taken samples of rumens contents for determining pH, and after that blood samples, in which, after the separation of blood serum, were determined glucose concentration, total proteins, albumin, globulin, urea, HDL cholesterol, LDL cholesterol, total bilirubin, calcium and phosphorus, as well as the activity of ALT and AST. By computation there was calculated the ratio between albumin and globulin, ALT and AST, and the ratio between calcium and phosphorus. Daily allowance and milk chemical composition ( percentage of fat, proteins and dry substance were determined at the end of the investigation period, that is on the 30th day of lactation, for each cow individually. Partial substitution of magnesium oxide with bentonite influenced milk production increase, but it was statistically insignificant. Besides that, in E

    The present study investigates the influence of supplementing Pediococcus acidilactici strain FT28 on serum biochemistry, carcass and physicochemical properties of meat in fattening pigs. A total of 36 piglets (28day) were randomly divided into three groups of four replicates of three animals in each. Each group was fed one of the experimental diet as basal diet alone (Control-T0); basal diet supplemented with Pediococcus acidilactici strain FT28 (swine origin probiotic-T1) and basal diet supplemented with Lactobacillus acidophilus NCDC-15 (dairy origin probiotic-T2). Increased (P<0.05) level of serum total protein and albumin, and decreased (P<0.05) triglyceride were observed with probiotic supplementation either of swine or dairy origin, compared to control. The level globulin and glucose were higher (P<0.05) in T1 group among the dietary groups. Carcass traits remained unaltered except for the weight of ham, kidney and spleen which were higher (P<0.05) in the T1 group. Water holding capacity and TBARS were improved (P<0.05) in the T1 group than control, however comparable to the T2 group. The ether extract, pH and sensory attributes (juiciness and appearance) were improved (P<0.05) in the T1 group among the dietary groups. It is evident from the present study that P. acidilactici FT28 could serve as probiotic for enhancing carcass quality and physicochemical properties of pork without influencing the blood metabolites.

    Dietary supplementation with echium oil (EO) containing stearidonic acid (SDA) is a plant-based strategy to improve long-chain (LC) n-3 (ω-3) polyunsaturated fatty acid (PUFA) status in humans. We investigated the effect of EO on LC n-3 PUFA accumulation in blood and biochemical markers with respect to age, sex, and metabolic syndrome. This double-blind, parallel-arm, randomized controlled study started with a 2-wk run-in period, during which participants (n = 80) were administered 17 g/d run-in oil. Normal-weight individuals from 2 age groups (20-35 and 49-69 y) were allotted to EO or fish oil (FO; control) groups. During the 8-wk intervention, participants were administered either 17 g/d EO (2 g SDA; n = 59) or FO [1.9 g eicosapentaenoic acid (EPA); n = 19]. Overweight individuals with metabolic syndrome (n = 19) were recruited for EO treatment only. During the 10-wk study, the participants followed a dietary n-3 PUFA restriction, e.g., no fish. After the 8-wk EO treatment, increases in the LC n-3 metabolites EPA (168% and 79%) and docosapentaenoic acid [DPA (68% and 39%)] were observed, whereas docosahexaenoic acid (DHA) decreased (-5% and -23%) in plasma and peripheral blood mononuclear cells, respectively. Compared with FO, the efficacy of EO to increase EPA and DPA in blood was significantly lower (∼25% and ∼50%, respectively). A higher body mass index (BMI) was associated with lower relative and net increases in EPA and DPA. Compared with baseline, EO significantly reduced serum cholesterol, LDL cholesterol, oxidized LDL, and triglyceride (TG), but also HDL cholesterol, regardless of age and BMI. In the FO group, only TG decreased. Overall, daily intake of 15-20 g EO increased EPA and DPA in blood but had no influence on DHA. EO lowered cardiovascular risk markers, e.g., serum TG, which is particularly relevant for individuals with metabolic syndrome. Natural EO could be a noteworthy source of n-3 PUFA in human nutrition.

    The objective of this study was to validate the novel integration of oscillometric (Vasotens(®)) technology into a BPLab(®) ambulatory blood pressure (BP) monitoring system to measure central BP, the aortic augmentation index, and pulse wave velocity (PWV) compared with the recommended and widely accepted tonometric method. The ARTERY Society guidelines for comparison of PWV measurement techniques were used as the basis for recruitment of 99 individuals (mean age 44±19 years, 52 males). The standard for comparison was the conventional "classic" SphygmoCor device. Accordance of the two methods was satisfactory (r=0.98, mean difference of 2.9±3.5 mmHg for central systolic BP; r=0.98, mean difference of -1.1±2.3 mmHg for central diastolic BP; r=0.83, mean difference of -2.6%±13% for aortic augmentation index; r=0.85, mean difference of 0.69±1.4 for PWV). The performance of Vasotens algorithms using an oscillometric ambulatory BP monitoring system is feasible for accurate diagnosis, risk assessment, and evaluation of the effects of antihypertensive drugs.

    The peripheral blood content in women, which, due to their occupation are exposed to low dose ionizing radiation effect, has been investigated. One hundred and ten women from 20 to 50 years of age and occupation service in a sphere of ionizing radiation from 6 months to 4 years (an average length of 2,5 years) were examined. The unequal external gamma irradiation was the fundamental factor of the radiation effect under conditions of occupational media. The mean annual dose did never exceed the maximum permissible limits. As control, a group of 106 clinically healthy women of the same age and working in the industry but not exposed to radiation effect, was formed. Hemoglobin quantity, erythrocytes and leukocytes number, differential count of leukocytes and thrombocytes number were analyzed. Not any statistically significant differences (p > 0,05) between the mean values of the studied parameters of the control group and this one of women exposed to occupational irradiation were observed. This analysis of the hematological parameters represents the first stage of the already undertaken dynamic examination of the health status of a new and relatively stable contingent of occupationally irradiated persons.

    This study investigated the effect of the biochemical and biophysical properties of the plasma membrane as well as membrane morphology on the susceptibility of human red blood cells to the cholesterol-dependent cytolysin pneumolysin, a key virulence factor of Streptococcus pneumoniae, using single cell studies. We show a correlation between the physical properties of the membrane (bending rigidity and surface and dipole electrostatic potentials) and the susceptibility of red blood cells to pneumolysin-induced hemolysis. We demonstrate that biochemical modifications of the membrane induced by oxidative stress, lipid scrambling, and artificial cell aging modulate the cell response to the toxin. We provide evidence that the diversity of response to pneumolysin in diabetic red blood cells correlates with levels of glycated hemoglobin and that the mechanical properties of the red blood cell plasma membrane are altered in diabetes. Finally, we show that diabetic red blood cells are more resistant to pneumolysin and the related toxin perfringolysin O relative to healthy red blood cells. Taken together, these studies indicate that the diversity of cell response to pneumolysin within a population of human red blood cells is influenced by the biophysical and biochemical status of the plasma membrane and the chemical and/or oxidative stress pre-history of the cell.

    Full Text Available Background: Elevation of the neutrophil to lymphocyte ratio (NLR has been shown to be an indicator of poor prognosis in many malignancies including recurrent glioblastoma multiforme. Objectives: This study was aimed at assessing if the NLR and other leukocyte counts and indices were deranged in treatment-naïve patients with primary brain tumors when compared with an age-matched healthy control group. Materials and Methods: This was a prospective comparative clinical observational study by design. A healthy control population was compared with treatment-naïve patients diagnosed with intra- and extraaxial brain tumors. Leukocyte counts (neutrophil, lymphocyte, monocyte, eosinophil, and basophil counts as well as leukocyte ratios such as the NLR and the monocyte to lymphocyte ratio (MLR were calculated. We also evaluated if the counts and indices were related to the tumor volume. Results: In all patients with tumors, the platelet and neutrophil counts were elevated when compared to the controls. In contrast, monocyte counts and the MLR were found to be decreased in patients with tumors when compared to the controls. The subset of patients with glioblastoma showed a significant increase in NLR when compared to the controls. Conclusions: Significant changes in the neutrophil, monocyte, and platelet counts as well as NLR and MLR were observed. Prospective longitudinal studies are required to determine the prognostic and therapeutic implications of these findings.

    The absolute difference between aortic and right atrial systolic pressure (systolic pressure gradient) and the difference between the aortic diastolic and right atrial diastolic pressure (coronary perfusion pressure) were evaluated in a series of 63 adult mongrel dogs undergoing five different methods of cardiopulmonary resuscitation (CPR). Fluid-filled pressure monitoring catheters were placed in the ascending aorta and right atrium in each of the animals after induction of anesthesia with morphine sulfate and 1% halothane and oxygen. The animals were then fibrillated with a transvenous electrode catheter that had been introduced into a ventricle. After a "down time" of 3 minutes during which no CPR was performed, the animals' lungs were ventilated, and one of five methods of CPR was initiated. The systolic pressure gradient and coronary perfusion pressure were measured in all animals 1 minute after CPR was begun, and in all but the group undergoing open-chest cardiac massage after 7 minutes and 17 minutes of CPR. The systolic pressure gradient and coronary perfusion pressure were greatest during open-chest cardiac massage (true cardiac compression), intermediate in external mechanical CPR (Thumper) and standard CPR (greater in small dogs than large dogs), and lowest in CPR performed with a combined thoracic and abdominal vest apparatus (predominantly thoracic pump). The observation that the systolic pressure gradient between intrathoracic chambers is largest in open-chest cardiac massage and smallest in vest CPR suggests that similar measurements recorded during the performance of human cardiac resuscitation may be useful in determining the mechanism of blood flow.

    Work-related stress can lead to various health problems ranging from job-related exhaustion to psychiatric and somatic diseases. Biomarkers of job-related exhaustion could help to improve our understanding of the biological mechanisms and might be useful to guide prevention and treatment strategies. The present study included 12 male cases suffering from job-related exhaustion and 12 matched healthy controls. Severity of exhaustion was assessed with the Maslach Burnout Inventory (MBI) and the Shirom-Melamed Burnout Measure (SMBM). Whole genome expression profiles derived from whole blood cells (baseline and following glucocorticoid-receptor (GR) stimulation with 1.5mg dexamethasone p.o.) and corresponding plasma cortisol levels were analyzed. All cases participated in regular aerobic exercise for 12 consecutive weeks and were then re-assessed at follow-up for exhaustion symptoms as well as for cortisol levels and gene expression profiles. At baseline, we found increased basal cortisol levels and an enhanced suppression of plasma cortisol concentrations following dexamethasone in cases suffering from job-related exhaustion. Gene expression analysis revealed that 1.6-fold more transcripts were significantly regulated by dexamethasone in cases as compared to controls. At follow-up after 12 weeks of regular exercise training which was accompanied by significantly improved exhaustion severity scores, cortisol levels and gene expression profiles of cases normalized to the levels observed in controls. In conclusion, we detected GR-induced neuroendocrine and gene expression changes in cases suffering from job-related exhaustion which are in line with an increased sensitivity of GR function. This GR dysregulation normalized with symptom recovery. Copyright © 2014 Elsevier Ltd. All rights reserved.

Recent studies have reported the role of hematological indices in contributing to the vascular injury in diabetic patients. Thus, the aim of this study was to determine hematological indices and their correlation with fasting blood glucose level and anthropometric measurement in type 2 DM patients in comparison with healthy controls. Methods: A comparative cross-sectional study was conducted at the chronic illness clinic of Gondar University Hospital from February to April 2015. A total of 296 participants (148 cases and 148 healthy controls were selected using systematic random sampling technique. Data were collected using a pretested structured questionnaire. Fasting blood glucose levels and hematological indices were determined by using Bio Systems A25 and Sysmex-KX 21N analyzers, respectively. Independent sample t-test, Mann–Whitney U-test, and correlation statistics were used. A P-value <0.05 was considered as statistically significant. Result: There was significant difference in red blood cell distribution width (47.3±2.6 fL vs 45.2±3 fL between diabetic patients and controls. Total white blood cells in 103/µL (6.59±1.42 vs 5.56±1.38, absolute lymphocyte count in 103/µL (2.60±0.70 vs 2.04±0.63, and absolute neutrophil count in 103/µL (3.57±1.46 vs 3.11±1.04 increased significantly in diabetic patients compared with controls, respectively.

    Full Text Available Aims: This study aimed to evaluate some relevant serum biochemical and hematological changes in concentration level involved firefighters in comparison to normal controls. Materials and Methods: This study involved two groups of male firefighters to participate in the study. The first group included 50 firefighters from Dammam while the second group included 50 firefighters from Khobar. An additional control group of 50 male nonfirefighters from both cities was included in the study. Blood samples were collected from all participants and investigated for some relevant biochemical, hematological differences and blood heavy metals between the three studied groups. Results: The results obtained showed that there were statistically significant differences in liver function, serum lipid profile, creatine kinase, lactate dehydrogenase, iron and ferritin, and blood picture in firefighters as compared with normal control group, while there were no statistically significant differences in the levels of blood heavy metals in firefighters as compared to normal controls. These results indicate that fire smoke mainly affects serum biochemical and hematological parameters but does not affect serum heavy metals levels. Conclusion: Such results might point out to the need for more health protective and prophylactic measures to try to avoid such hazardous health effects that might endanger firefighters under their highly drastic working conditions, and firefighters must be under continuous medical follow-up through a standard timetabled medical laboratory investigations to allow for the early detection of any biochemical or hematological changes.

    The composite histological endpoint comprising nonalcoholic steatohepatitis (NASH) and NAFLD activity score ≥4 and advanced fibrosis (F ≥ 2) ("fibrotic NASH") is becoming an important diagnostic target in NAFLD: it is currently used to select patients for inclusion in phase III therapeutic trials and will ultimately be used to indicate treatment in clinical practice once the new drugs are approved. To develop a new blood test specifically dedicated for this new diagnostic target of interest. Eight Hundred and forty-six biopsy-proven NAFLD patients from three centres (Angers, Nice, Antwerp) were randomised into derivation and validation sets. The blood fibrosis tests BARD, NFS and FIB4 had poor accuracy for fibrotic NASH with respective AUROC: 0.566 ± 0.023, 0.654 ± 0.023, 0.732 ± 0.021. In the derivation set, fibrotic NASH was independently predicted by AST, HOMA and CK18; all three were combined in the new blood test MACK-3 (hoMa, Ast, CK18) for which 90% sensitivity and 95% specificity cut-offs were calculated. In the validation set, MACK-3 had a significantly higher AUROC (0.847 ± 0.030, P ≤ 0.002) than blood fibrosis tests. Using liver biopsy in the grey zone between the two cut-offs (36.0% of the patients), MACK-3 provided excellent accuracy for the diagnosis of fibrotic NASH with 93.3% well-classified patients, sensitivity: 90.0%, specificity: 94.2%, positive predictive value: 81.8% and negative predictive value: 97.0%. The new blood test MACK-3 accurately diagnoses fibrotic NASH. This new test will facilitate patient screening and inclusion in NAFLD therapeutic trials and will enable the identification of patients who will benefit from the treatments once approved. © 2018 John Wiley & Sons Ltd.

  2. Comparison of the Blood Level OF Leptin in Umbilical Cord of Newborns of Mothers With Gestational Diabetes and Normal Mothers and Its Relationship With Growth Indices of Newborns

    Full Text Available Background Diabetes is defined as an abnormal increase in blood glucose levels and is the most common disease that can complicate pregnancy. Leptin, a hormone produced mainly in adipose tissue, plays an important role in preventing fat accumulation in tissues such as skeletal muscle and myocardium and can be used to evaluate changes in lipid levels effectively. Leptin cannot cross the placental barrier, and its level in the umbilical cord is of fetal origin. Objectives Due to the lack of similar studies in Ahvaz, we aimed to determine the relationship between umbilical blood levels of this hormone with growth indices of newborns with normal mothers and mothers with gestational diabetes mellitus (GDM. Materials and Methods After delivery and using the aseptic method, 5 mL of blood from the umbilical vein was taken immediately by staffs to separate serum and was then stored at −20°C. Serum level of leptin was measured using the Elisa method in two groups: “case” and “control.” All information collected in the questionnaires was analyzed using SPSS-19 software as well as other statistical methods. Results Serum leptin levels in the cord blood of mothers with GDM were significantly higher than in normal mothers. There was a significant relationship between serum leptin levels and birth weight in infants with diabetic mothers. In this study, no significant correlation was observed between cord leptin levels and other growth indices. Conclusions Changes in neonatal leptin levels can reflect changes in the body fat tissue and neonatal birth weight and could be effective in predicting weight gain in newborns with mothers who have gestational diabetes and may reduce birth trauma or future complications.

    Full Text Available Present study analyzed the changes in peripheral blood testosterone concentrations and testicular cytogram in relation to age and semen quality in crossbred males. Three different age groups of crossbred males viz. bull calves (6 months, n = 5, young bulls (15 months, n = 5 and adult bulls (4 to 6 years, n = 8 were utilized for the study. Testicular fine needle aspiration cytology technique was used to quantify testicular cytology and their indices. Peripheral blood testosterone concentrations were measured using enzyme-linked immunosorbent assay method. Semen samples collected from adult bulls were microscopically evaluated for quality parameters. Mean peripheral blood testosterone concentrations in bull calves, young bulls and adult bulls were 2.28±0.09 ng/mL, 1.42±0.22 ng/mL and 5.66±1.08 ng/mL respectively, and that in adult bulls were significantly different (p<0.01 from young bulls and bull calves. There was no significant difference between the proportion of different testicular cells in bull calves and young bulls. Between young and adult bulls, significant differences (p<0.01 were observed in the proportion of spermatocytes, spermatozoa, and sperm: Sertoli cell ratio. The proportions of Sertoli cells showed a significant difference (p<0.01 between the three age groups. The number of primary spermatocytes had a positive correlation with peripheral blood testosterone concentrations in bull calves (r = 0.719, p<0.01. Number of Sertoli cells per 100 germ cells was negatively correlated with blood testosterone concentration in young bulls (r = −0.713, p<0.01. Among different semen parameters in adult bulls, ejaculate volume (r = 0.790, p<0.05 had positive relationship, and sperm motility had significant negative correlation (r = −0.711, p<0.05 with testosterone concentrations. The number of Sertoli cells and Sertoli cell index had a positive correlation with various semen quality parameters (p<0.001. Results of the present study

    Full Text Available Hibiscus sabdariffa L. has been used traditionally as herbal medicine and has been documented to have a broad range of therapeutic effects. The present study aimed to investigate the effects of chronic administration of aqueous extract of flowers of Hibiscus sabdariffa on the histology of the kidney and some biochemical indices of renal function in male Wistar rats. Twenty (20 Wistar rats were randomly divided into four (4 groups of five rats each. The extract was administered orally in doses 200, 500, and 800 mg/kg body weight for 21 days. The kidney was harvested and processed histologically and blood samples were taken for biochemical assays. The histological results showed dose dependent pathological states and the biochemical analysis revealed a dose dependant variation in renal indices. These results suggest that chronic administration of aqueous extract of Hibiscus sabdariffa may be toxic to the kidney.

    Although used mainly for transplantation of hematopoietic stem cells in the treatment of blood disorders, umbilical cord blood (UCB)-based therapies are now being used increasingly for novel applications in nonhematopoietic diseases and as a form of cellular regenerative therapy or immune modulation. We performed a systematic scoping review by searching Medline, EMBASE, and the Cochrane Library for published articles, and we searched www.clinicaltrials.com and the World Health Organization International Clinical Trials Registry Platform to describe the breadth of published studies and ongoing clinical activity in umbilical cord-based cellular therapy for regenerative therapy and immune modulation. The most commonly published area of expertise in the use of UCB-derived cellular transplantation for novel indications is for neurological disorders and this remains the most active area of study in ongoing registered trials. An increasingly broad range of disorders, however, are reflected in ongoing registered trials, which suggests greater activity, interest, and investment in UCB-derived cellular therapy. Interestingly, adult patients compose the majority of patients reported in published reports and registered ongoing clinical studies continue to enroll predominantly adult subjects. Geographically, Asian countries appear most active in UCB-derived cellular therapy and our analysis of ongoing studies suggests this trend will likely continue. Regular assessment of published and ongoing activity in UCB transplantation for emerging novel indications will be critical for informing UCB banking establishments and funding agencies to guide changes in banking practices related to emerging trends in cell therapy.

    Vitamin D supplementation has been shown to decrease insulin resistance through which it might cause fatty liver. Fatty liver increasingly results in type 2 diabetes mellitus (T2DM). Insulin resistance and fatty liver are particularly closely related. The aim of present study is to examine the effect of vitamin D supplementation on blood sugar and different indices of insulin resistance in patients with non-alcoholic fatty liver disease (NAFLD). This randomized placebo-controlled clinical trial was conducted on 60 patients with NAFLD, who were divided equally into intervention and control groups. Patients in the intervention group received vitamin D3 (50,000 IU) and patients in the control group received placebo capsules every week for 10 weeks. Blood sugar, homeostatic model assessment-insulin resistance (HOMA-IR), and homeostatic model assessment-beta cell (HOMA-B) were checked at baseline and after 10 weeks of the intervention. Adjustment for variables was performed by analysis of covariance (ANCOVA). Vitamin D supplementation resulted in increased serum 25-hydroxy vitamin D [25(OH) D] concentration in the intervention group compared to the control group [+68 (12) vs. -1.9 (2.44); P = 0.001]. Intake of vitamin D supplements led to a marginally significant decrease in fasting blood glucose [FBS: -12 (4) in the intervention group compared to - 3 (2) in the control group; P = 0.055]. Also, HOMA-IR decreased in the intervention group compared to the control group [-1.75 (0.23) vs. 0.12 (0.41); P = 0.066]. Vitamin D supplementation resulted in decreased HOMA-IR and FBS concentration in patients with NAFLD; however, it did not affect the insulin level and HOMA-B significantly.

    We examined the factors considered to change body composition and blood biochemistry indicators in menopausal middle-aged and elderly women. These changes result from exercise by walking as part of their daily activities and lemon consumption by women who live on the small islands of the Seto Inland Sea, Japan's largest citrus fruit (lemon)-producing region. Between September 2011 and March 2012, we recorded the daily lemon consumption and the number of steps taken by 101 middle-aged and elderly female lemon farmers. We also measured their body dimensions, body compositions, and blood pressure pulse wave velocity and conducted blood tests before and after the survey period. The results before and after the survey period were compared by the t-test and associations were determined on the basis of Pearson's correlation coefficient. Covariance structural analysis was carried out to determine causal associations. From the results of covariance structure analysis, lemon intake did not have a direct impact on each item examined. The third item, i.e., "the factors related to arteriosclerosis," was affected indirectly via citric acid and fatigue, and anticoagulation was shown. The fourth item, i.e., "the factors related to maintenance of muscle mass," which is affected by menopausal years and the change in walking speed, was shown to be associated with the second item, i.e., "the factors related to lipid metabolism." Menopausal years affected the first, third and fourth items. Lemon intake did not have a direct impact on each item. Lemon has been shown to indirectly affect the third item through citric acid. Walking affected the second item, the level of total cholesterol, such as HDL cholesterol, through the fourth item. The importance of providing services that lead to sustained physical activity and a well-balanced metabolism between lipids and carbohydrates has been shown.

    Capsule endoscopy (CE) is the gold standard to diagnose small bowel bleeding. The "suspected blood indicator" (SBI) offers an automated detection of active small bowel bleeding but validity of this technique is unknown. The objective was to analyze specificity and sensitivity of the SBI using the second small bowel capsule generation for the detection of active bleeding. This is a retrospective analysis of all patients (199) who attended our clinic for CE from June 2008 through March 2013. The second-generation PillCam SB 2 capsule was used for detection of (1) luminal blood content and (2) potentially responsible small bowel lesions. The findings of an independent investigator were correlated to SBI findings and a number of SBI markings were analyzed by a receiver operating characteristic (ROC). In 157/199 cases, no sign of active bleeding or altered blood was detected. One hundred and thirty-seven of these 157 cases provided at least one SBI marking and a mean of 18.4 positive SBI markings per record were found. In 20 cases, neither SBI nor the human investigator detected abnormalities. Thirteen patients showed investigator-detected minor bleeding with mean SBI findings of 36 positive screenshots per record. When major bleeding was diagnosed by the investigator (n = 29), SBI detected a mean of 46.6 SBI-positive markings. SBI turned positive in 179 patients, whereas the investigator detected active bleeding in 42 cases. All patients with active bleeding were detected by SBI (sensitivity 100%, specificity 13%). ROC analysis revealed 51.0 SBI markings being the optimal cutoff for active versus no bleeding (sensitivity 79.1%, specificity 90.4%, misclassification of 15.3%). The new SBI software is a reliable tool to exclude active bleeding and/or major lesions but analysis of the CE video by a trained investigator is still important for the detection of lesions responsible for past bleeding.

    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

    Concerning the biochemical reactions of the lung parenchyma to irradiation the following points have been developed. Role of biochemically active substances (histamine, serotonin, kinins, catecholamines, prostaglandins) in the early reaction of the lung to irradiation, their common feature being their vascular impact point. Lung irradiation and lipids (fatty acids and lipid metabolism in general); irradiation, by raising the proportion of unsaturated at the expense of saturated fatty acids, may give rise to serious physiological respiratory disorders. Lung irradiation and blood fluidity (fibrinolytic activity, heparin, platelet factors). Pulmonary interstitium and irradiation (of the three interstitium components collagen plays a preferential part). Irradiation and immunological lung reaction (reasons behind the immunological theory, immunological assistance, immunological mechanism of pulmonary reactions towards pollutants). Enzymatic lung radiolesion indicators. Three kinds of physiological changes have been considered. Vascular physiology disturbances caused by the initial biochemical reactions; anomalies of physiological or functional trials, images of the lesion formed; disorders of the cell physiology of carcinogenesis [fr

Blood samples were evaluated for hemato-biochemical parameters following standard procedures. Results indicated seroprevalence of brucellosis 20.13 and 16.23% in horses by RBPT and SAT, respectively. Brucellosis does not lead to any significant change in hematological and biochemical parameters in relation to age, sex, body condition and lactation except few parameters. The values of erythrocyte sedimentation rate, neutrophil, basophil and alkaline phosphatase significantly decreased in brucellosis positive animals as compared to healthy animals whereas lymphocytes and alanine aminotransferase were in opposite order. It was concluded from the results that prevalence of brucellosis in horse population is of concern; therefore, control measures should be opted so that its zoonotic threat is curtailed. (author)

    Myocardial blood flow during pharmacological vasodilatation is depressed in patients with idiopathic dilated cardiomyopathy even the in absence of overt heart failure; the extent of myocardial blood flow abnormalities is not predictable by left ventricular ejection fraction (LVEF) and diastolic dimensions. To assess whether myocardial blood flow impairment in idiopathic dilated cardiomyopathy without overt heart failure can be related to Doppler-derived dP/dt and to echocardiographically determined left ventricular end systolic stress - which is linked to myocardial blood flow reserve in advanced disease. Twenty-six patients, New York Heart Association Class I-II, (LVEF 37.4 +/- 1.4%, left ventricular diastolic dimensions 62.6 +/- 0.9 mm) underwent resting/dipyridamole [13N]NH3 flow positron emission tomography and an ultrasonic study. Regional myocardial blood flow values (ml/min per g) were computed from positron emission tomography data in 13 left ventricular (LV) myocardial regions and averaged to provide mean myocardial blood flow and myocardial blood flow reserve, defined as dipyridamole/resting mean myocardial blood flow ratio. Resting myocardial blood flow was 0.686 +/- 0.045, dipyridamole myocardial blood flow 1.39 +/- 0.15 and myocardial blood flow reserve 2.12 +/- 0.2, lower than in controls (P < 0.01). The ratio dP/dt was directly related to dipyridamole myocardial blood flow and myocardial blood flow reserve (r = 0.552 and 0.703, P < 0.005 and P < 0.0001); no relation was found between myocardial blood flow and LVEF left ventricular diastolic dimensions, and left ventricular end systolic stress. In idiopathic dilated cardiomyopathy patients without overt heart failure, the extent of myocardial blood flow reserve impairment is related to dP/dt but not to more classical indices of left ventricular function.

    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.

    The long time use of opium has some effects on serums biochemical factors, the determination of this variation is a new approach in understanding off addiction and relive of drug abuser health. Hence in this study, these indicators in person who were withdrawing of opium have been studied. In this cross-sectional study bloods biochemical factors such as fasting blood sugar (FBS), sodium (Na), calcium (Ca), uric acid (UA), blood urea nitrogen (BUN), creatinine, cholesterol, total protein, and fibrinogen in three groups serum were studied: (1) Who had been permanent opium users more than 2 years (case). (2) Dependent person who has taken one month addiction withdrawal course (control). (3) A healthy group that had been demographically similar to the other groups. According to these study findings, FBS serum level in the case group is lower than control group. Serum level of Na, creatinine, and blood triglyceride (TG) in case study are higher than group control. Concentration of potassium, Ca, UA, BUN, cholesterol, total serum protein, fibrinogen, and thrombin time in case study and group control showed no significant difference. Also, in withdrawing case serum level of Na, Ca, UA, BUN, creatinine, and TG significantly increase and thrombin time decrease. According to this study not only the longtime use of opium but also opium with drawerin opium dependent people can change their serum biochemical factors. So recognition, treatment, and prevention of this change could be a new step in improving of health and condition of patients.

    Tumor cells communicate with stromal cells, including cancer-associated fibroblasts (CAFs) and tumor-associated macrophages (TAMs), to form microenvironment inhibiting immune responses. Regulatory T cells (Tregs, CD4+CD25+FoxP3+) stimulate immune tolerance and facilitate tumor progression. We analyzed the changes in Treg frequencies assessed using flow cytometry in the peripheral blood of patients with urothelial bladder cancer before and after tumor-removal. Changes in Treg frequency were investigated in relation to clinicopathomorphological indicators of tumor malignancy and expression of RCAS1 on CAFs and TAMs. Higher Treg frequencies were observed in early phase of tumor growth (pTa-pT2), in larger tumors, with more aggressive type of invasion, and with expression of RCAS1. The later phase of tumor development, accompanied by a nonclassic differentiations and pT3-pT4 advancement, had lower number of tumor infiltrating lymphocytes (TILs) and lower Treg frequency. Furthermore, in pT2-pT4 tumors, a decreased post-surgery Treg frequency was associated with poorer prognosis: patients with the lowest frequency of Tregs died first. These findings strongly suggest that the Treg frequencies at later phase of tumor growth, associated with a low anti-tumor response, represent a new and important prognostic indicator in urinary bladder cancer.

    In boron neutron capture therapy (BNCT), positron emission tomography (PET) with 4-borono-2- 18 F-fluoro-phenylalanine (FBPA) is the only method to estimate an accumulation of 10 B to target tumor and surrounding normal tissue after administering 10 B carrier of L-paraboronophenylalanine and to search the indication of BNCT for individual patient. Absolute concentration of 10 B in tumor has been estimated by multiplying 10 B concentration in blood during BNCT by tumor to blood radioactivity (T/B) ratio derived from FBPA PET. However, the method to measure blood radioactivity either by blood sampling or image data has not been standardized. We compared image-derived blood radioactivity of FBPA with blood sampling data and studied appropriate timing and location for measuring image-derived blood counts. We obtained 7 repeated whole-body PET scans in five healthy subjects. Arterialized venous blood samples were obtained from the antecubital vein, heated in a heating blanket. Time-activity curves (TACs) of image-derived blood radioactivity were obtained using volumes of interest (VOIs) over ascending aorta, aortic arch, pulmonary artery, left and right ventricles, inferior vena cava, and abdominal aorta. Image-derived blood radioactivity was compared with those measured by blood sampling data in each location. Both the TACs of blood sampling radioactivity in each subject, and the TACs of image-derived blood radioactivity showed a peak within 5 min after the tracer injection, and promptly decreased soon thereafter. Linear relationship was found between blood sampling radioactivity and image-derived blood radioactivity in all the VOIs at any timing of data sampling (p radioactivity measured in the left and right ventricles 30 min after injection showed high correlation with blood radioactivity. Image-derived blood radioactivity was lower than blood sampling radioactivity data by 20 %. Reduction of blood radioactivity of FBPA in left ventricle after 30 min of FBPA

    Normal response to different types of exercise needs to be established before performance, training level, or exercise intolerance can be assessed. The aim of this research was to describe the hematologic and biochemical changes that dogs undergo during an agility competition. Fifteen dogs were subjected to an agility test that covered a distance of 360-400 m with 40 obstacles. Basal venous blood samples were drawn 1 week before the competition, immediately after exercise, and at 5, 15, and 30 minutes of recuperation. A CBC, plasma biochemical profile, and lactate concentration were determined by standard methods using automated analyzers. Serum cortisol concentration was measured by competitive immune-enzyme analysis; insulin was measured by sandwich ELISA. Hematologic response to the agility test consisted of significant increases in RBC count, hemoglobin concentration, and HCT, with no change in total protein concentration. Serum triglyceride concentrations were increased postexercise, with highest values observed at 30 minutes of recuperation. Postexercise lactate concentrations exceeded the anaerobic threshold of 4 mmol/L. Serum lactate dehydrogenase activity was significantly higher after 30 minutes of recuperation. Significant differences were not observed in other analytes. Our results indicate that agility competitions induce mild to moderate changes in hematologic and biochemical results consistent with splenic contraction, increased lipolysis, and utilization of anaerobic pathways involved in energy resynthesis in muscle.

    Biological indicators are used for assessing DNA damage and repair in cells exposed to ionising radiation. DNA Double-strand breaks (DSBs) have been known as one of the most significant lesion producing lethal and mutagenic effects in irradiated cells. A new biological marker for DSBs is the presence of γ-H2AX foci in cells nucleus after exposure to ionising radiation. γ-H2AX formation was analysed in human lymphocytes. The blood was obtained from a same donor in three different occasions and exposed to doses of 0, 0.2 and 0.5 Gy of gamma rays with a dose-rate of 1.2 Gy/min. After blood irradiation the lymphocytes were incubated 30 minutes at 37 C degrees, isolated, fixed with paraformaldehyde, and spread on a microscope slide using a Cytospin. The slides were stored at -20 C degrees and immuno-stained the next day and 14, 16, 27 and 37 days after irradiation to test the influence of the storage time on results. The number of foci per cell was scored automatically, in about 200 cells per dose using HISTOLAB and CARTOGRAPH software. The mean of number of foci/cell for samples was as follow 0 Gy= 0.15 ± 0.04, 0.2 Gy =2.06 ± 0.25 and 0.5 Gy=5.21 ± 0.36 without appreciable effect of the storage time on the final results. Nevertheless some aspects require additional research, particularly the background values of the assay. A higher variability of DNA damage was observed for control samples, than for exposed ones. The influence of the number of cells scored on this variability should be tested. (author)

    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.

    Full Text Available Introduction: Beta thalassemia trait (BTT must be differentiated from iron deficiency anemia to avoid unnecessary iron therapy and for the prevention of thalassemia major by genetic counseling. In a tertiary care hospital, it is vital that the screening tool is not only sensitive but also specific so as to be cost effective and save time. Aim: The aim of this study was to evaluate the new Sehgal index and compare it to existing complete blood count-based indices for the best combination of sensitivity and specificity to predict BTT. Materials and Methods: Study was done in 2 phases - Phase 1: A retrospective analysis of 1022 consecutive high-performance liquid chromatography (HPLC cases from July 2008 to June 2011. Phase 2: A prospective analysis of 973 consecutive HPLC cases from July 1, 2011 to June 10, 2013 was done to confirm the results of Phase 1 and the applicability of the new Sehgal index. Results: Prevalence of BTT was 28.8% (294/1022 and 25.39% (247/973 in Phase 1 and Phase 2, respectively. Receiver operating characteristic-area under the curve and Youden index was highest for new Sehgal index, followed by Mentzers index <14. The prospective study shows results similar to those in Phase 1 confirming the superiority of the above two indices. Conclusion: Sehgal index and Mentzers index <14 showed the best combination of sensitivity and specificity in predicting BTT. The best indices or combination can be used as a "validated flag rule" in the analyzer middleware program in a hospital for identifying suspected cases of BTT.

    Full Text Available ABSTRACT The objective of this study was to evaluate stress responses in dog snapper (Lutjanus jocu during transport by evaluating their hematological and biochemical responses. Twenty-five wild dog snapper specimens were used in the experiment (220 ± 68 g and 24.5 ± 2.5 cm total length. Blood samples were collected prior to transport (control, and fish were placed in two transport boxes, one with anesthetic and one without anesthetic. Immediately after transport and after 24 h, blood was collected from the fish that underwent each treatment (with anesthetic and without anesthetic. Biochemical and hematological results demonstrated the inefficiency of benzocaine as a stress reliever during handling and transport. Biochemical parameters revealed the effects of stress during transport, and after 24 h, glucose levels and hematological parameters (hemoglobin, erythrocytes, leukocytes, neutrophils and MCH showed a tendency to return to control levels. This study is the first to report stress response measurements of hematological and biochemical indicators in dog snapper, representing an important basis for the planning of future experiments involving the transport and handling of this fish species.

    Full Text Available OBJECTIVE: The objective of this analysis was to test the impact of daily supplementation with multiple micronutrients (MM during pregnancy on Zn, vitamin A and folate status compared to iron only (Fe. MATERIAL AND METHODS: The study was carried out during 1997-2000 in a semi-urban community in Morelos state, Mexico. Women were randomly assigned to MM (n= 249 or Fe (n= 258 and received supplements daily (6 d/wk under supervision by the field team from recruitment (approximately 9 weeks pregnancy until delivery. Blood samples were collected on a sub-sample of women at baseline, 32 weeks pregnancy and one month postpartum (1PP and assessed for serum zinc, retinol and whole blood folate (baseline and 1PP only. A breast milk sample was extracted at 1PP and assessed for retinol content. RESULT: At baseline there was no significant difference between supplementation groups in mean Zn, retinol or folate concentrations or the prevalence of deficiencies (Zn 12.2%, vitamin A 2.8%, folate 5.3%. Mean change in Zn and retinol concentrations from baseline to 32 weeks pregnancy did not differ between groups or between baseline and 1PP for Zn, retinol or folate. At 1PP, there was a tendency (p= 0.09 towards a lower prevalence of folate deficiency/depletion in the MM group (10.0% than the Fe group (18.5%. CONCLUSIONS: MM supplementation during pregnancy did not improve zinc or vitamin A status compared to Fe only. There is some indication that folate status may have improved with MM supplementation despite low prevalence of deficiency. While lack of response in serum retinol may be explained by generally adequate status, the lack of impact on zinc status requires further exploration.OBJETIVO: Evaluar el efecto de la suplementación diaria con múltiples micronutrimentos (MM durante el embarazo en el estado de zinc, vitamina A y folato comparado con la suplementación sólo con hierro (Fe.

    To determine whether vitamin E (dl-..cap alpha..-tocopherol) supplementation of the diet provides protection from inhaled oxidants such as ozone (O/sub 3/) in community air pollution, its effects were studied in healthy adult volunteers. Experimental groups received 800 or 1600 IU of vitamin E for 9 weeks or more; control groups received placebos. Double-blind conditions were maintained throughout the study. Biochemical parameters studied included red blood cell fragility; hematocrit and hemoglobin values; red cell glutathione concentration; and the enzymes acetylcholinesterase, glucose-6-phosphate dehydrogenase, and lactic acid dehydrogenase. No significant differences between the responses of the supplemented and placebo groups to a controlled O/sub 3/ exposure (0.5 ppM for 2 h) were found for any of these parameters. The results indicate that vitamin E supplementation in humans, at the levels employed in this experiment, gives no added protection against blood biochemical effects of O/sub 3/ in intermittently exercising subjects under exposure conditions simulating summer ambient air pollution episodes.

    To evaluate the correlation between the coronary sinus flow and the infusion volume in the coronaries and assess the performance of coronary sinus flow in predicting coronary artery occlusion in an isolated pig heart. The coronary sinus flow was measured in 16 isolated pig hearts by pulsed Doppler ultrasound. The correlation between the coronary sinus flow and the infusion volume in different coronary artery was analyzed, and the performance of coronary sinus flow in predicting different coronary artery occlusion was deducted. There were no statistically significant differences between the coronary sinus flow and the infusion volume in different coronary artery (p>0.05). The correlations between the coronary sinus flow and the infusion volume in left anterior descending coronary artery (LAD), left circumflex coronary artery (LCX), LAD and LCX, and LAD, LCX and right coronary artery (RCA) were all higher than 0.85 (p85% sensitivity and specificity. Excepting RCA mild occlusion (80% sensitivity and specificity. Conclusions The coronary sinus flow measured by pulsed Doppler ultrasound can effectively and exactly reflect the infusion volume in coronaries, which is a powerful indicator of coronary blood supply.

    There are numerous reports of the effect of inulin on the bioavailability of mineral compounds. However, there are no conclusive reports concerning its beneficial impact (or lack thereof) in the case of such essential trace elements as iron, copper, or zinc. The aim of the study was to compare the effects of inulin addition with different degrees of polymerization (DPs) on growth performance in fatteners as well as on blood plasma concentrations of iron, copper, and zinc and selected hematological indices. The experiment was conducted throughout the fattening period (up to a body weight of approximately 115 kg) on 112 weaners with an initial weight of 25.0 ± 0.5 kg divided into 7 groups. The first group served as a control, while the other groups received increasing doses (1, 2, and 3 %) of standard inulin (SI; DP av  ≥ 10) or long-chain inulin (LCI, DP av  ≥ 23) in complete mixtures. Compared with the control, the supplementation of the mixtures with inulin increased the average daily gains, the final body weight, and the plasma content of trace elements (P inulin with a lower polymerization degree (P inulin polymerization degree, a higher final body weight and increased copper (P inulin addition was found to have modified the analyzed indices, and the optimal supplementation level was estimated at 20  g·kg -1 diet. Inulin with the higher DP exerted a more pronounced effect on the analyzed properties.

    Full Text Available The aim of the present study was to determine the effects of propylene glycol on metabolic variables of hepatic function, body condition score, milk fat-protein concentration and reproductive performance of dairy cows after ending administration. Postparturient dairy cows (n = 200 of Holstein Friesian breed were divided into two groups of 100 individuals. The experimental group received during days 0-7 post partum an oral daily dose of 600 ml of propylene glycol; the control group was without any supplement. The hepatic enzymes, glucose, cholesterol and serum albumin were measured on days 10-15, 45-50 and 70 post partum. Reproduction indicators of dairy cows were calculated from the farm recording data and the milk data record from a regular dairy control (days 10, 20, 30, and 50 post partum. Animals that received propylene glycol in the first 7 days post partum had reduced activities of aspartate transaminase and gamma-glutamyl transferase, elevated cholesterol concentration (P 0.05 and low milk fat percentage (P P 0.05. Our results suggest that some blood indicators of hepatic function, milk fat concentration and calving to first oestrus interval can be improved for 70 days post partum by the use of propylene glycol drenching in the first 7 days post partum. The beneficial effect of this treatment could be evaluated by easily available data, which can be used by practitioners in the field to analyze fertility problems in dairy herds and more exactly to examine whether metabolic stress, among other factors, is involved in the fertility problem.

    Hydrocephalus is associated with enlargement of cerebral ventricles. We hypothesized that magnetic resonance (MR) imaging parameters known to be influenced by tissue water content would change in parallel with ventricle size in young rats and that changes in blood-brain barrier (BBB) permeability would be detected. Hydrocephalus was induced by injection of kaolin into the cisterna magna of 4-week-old rats, which were studied 1 or 3 weeks later. MR was used to measure longitudinal and transverse relaxation times (T1 and T2) and apparent diffusion coefficients in several regions.

MR characteristics cannot be used as direct surrogates for water

    Full Text Available Shock is a clinical condition characterized by decreased blood flow to vital organs due to imbalance between size of vascular bed and effective circulating blood volume and the inability of body tissues to metabolize nutrients normally. The decreased blood flow to vital organs like kidney, liver, spleen, brain etc. is caused by pulling and stagnation blood elsewhere in circulation. The defective blood flow to tissues implies incomplete oxygen supply to the cells, tissues and organs consequent effect being interference with metabolism. It is very essential to study physicobiochemical aspect of shock because after knowing the pathways involved in various physio -pathological processes, we can undertake effective treatment and there by shock can be satisfactorily treated and prevented. Following are the various physico-biochemical processes stated by various workers to study the shock. [Vet. World 2009; 2(4.000: 161-162

    The Strep-Zym identification system, a combination of 23 enzymatic tests, allowed a rapid biochemical characterization of Streptococcus uberis. The biochemical profiles of the S. uberis cultures clearly differed from those of S. agalactiae and S. dysgalactiae. Serological grouping of S. uberis revealed polysaccharide antigens of groups E, G, P and U. Some cultures of S. uberis demonstrated CAMP-like synergistic hemolytic activities on sheep blood agar and reacted specifically with the lectins of Helix pomatia and Dolichos biflorus. The occurrence of group polysaccharides, CAMP-like reactivities, and the lectin agglutination reactions were obviously not related to each other or to any of the biochemical properties. These reactions, possibly of importance as virulence factors, might serve as epidemiological markers.
