Hemato-Biochemical studies on Egyptian Buffaloes and Calves naturally infected with Foot and Mouth Disease Virus serotype SAT 2

Foot and mouth disease (FMD) is a highly contagious viral disease of all cloven footed domestic and wild animals. This work was planned to study the different markers for diagnosis of FMDV serotype Sat2 in adult buffaloes and calves including clinical, hematological and biochemical examinations. A total number of sixty animals were divided into four groups. The first group was apparently healthy adult buffaloes, while the second was naturally infected adult buffaloes, a third group was apparently healthy suckling calves and finally the fourth group was naturally infected suckling calves. The recorded clinical signs were fever, salivation, loss of appetite, depression, lameness, blisters or vesicles, erosions and ulcers in the mucosa of the mouth, tongue, lips, gums, pharynx, palate and between the claws. Anemia, leucopenia, lymphopenia and monocytopenia were recorded in infected adult buffaloes and calves. Myocardial injury proved by presence of degenerated myocardial fibers and lymphocyte cell infiltration with a significant increase in cardiac markers like cardiac torponin I, CPK and LDH in addition to a significant hyperkalemia, hypocalcaemia and hypomagnesemia in buffaloe calves. Moreover, electrophoresis showed hyoproteinemia, hypoalbuminemia and hypoglobulinemia in infected animals. It could be concluded that the elevation of cardiac markers emphasized that FMD is more severe in young calves than adult animals. Therefore, it is recommended to evaluate the prognosis of FMD infection in calves by these markers

Serological, hematological, Biochemical and Oxidative Markers During Foot and Mouth Disease Serotype ‘O’ Infection, Egypt

Foot and mouth disease (FMD) is an extremely grave communicable disease of livestock. It affects all wild and domestic animals with cloven hoof. It is caused by Aphtho virus (Apthous fever) or (FMDV) foot and mouth disease virus which is originated from family Picornaviridae. 30 adult female water buffaloes, 3-5 years old infected with FMD serotypes, O. These animals were located at Sharkia governorate, Egypt during the period beetwen December 2014 to March 2015. Hematological findings showed no significant change in erythrogram and reduction in total leukocytes in the early stage of FMDV infection. Moreover development of macrocytic normochromic anemia and increase in total leukocytes and lymphocytic counts was reported in the late stage of infection. A significant decrease in cholesterol , progesterone , total proteins, albumin , globulins, calcium and sodium levels in infected groups, while a significant increase in serum activities of ALT ,AST, glucose, total, direct ,indirect bilirubine, phosphorous potassium, NO. MDA, CK-MB, LDH and CTNI. Without alterations in creatinine level

The role of nutrition related genes and nutrigenetics in understanding the pathogenesis of cancer

AbstractNutrition has a predominant and recognizable role in health management. Nutrigenetics is the science that identifies and characterizes gene variants associated with differential response to nutrients and relating this variation to variable disease states especially cancer. This arises from the epidemiological fact that cancer accounts for a high proportion of total morbidity and mortality in adults throughout the world. There is much evidence to support that genetic factors play a key role in the development of cancer; these genetic factors such as DNA instability and gene alterations are affected by nutrition. Nutrition may also lead to aberrant DNA methylation, which in turn contributes to carcinogenesis. The aim of this work is to clarify the basic knowledge about the vital role of nutrition-related genes in various disease states, especially cancer, and to identify nutrigenetics as a new concept that could highlight the relation between nutrition and gene expression. This may help to understand the mechanism and pathogenesis of cancer. The cause of cancer is a complex interplay mechanism of genetic and environmental factors. Dietary nutrient intake is an essential environmental factor and there is a marked variation in cancer development with the same dietary intake between individuals. This could be explained by the variation in their genetic polymorphisms, which leads to emergence of the concept of nutrigenomics and nutrigenetics

Plasma Elaidic Acid Level as Biomarker of Industrial Trans Fatty Acids and Risk of Weight Change: Report from the EPIC Study

Background Few epidemiological studies have examined the association between dietary trans fatty acids and weight gain, and the evidence remains inconsistent. The main objective of the study was to investigate the prospective association between biomarker of industrial trans fatty acids and change in weight within the large study European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Methods Baseline plasma fatty acid concentrations were determined in a representative EPIC sample from the 23 participating EPIC centers. A total of 1,945 individuals were followed for a median of 4.9 years to monitor weight change. The association between elaidic acid level and percent change of weight was investigated using a multinomial logistic regression model, adjusted by length of follow-up, age, energy, alcohol, smoking status, physical activity, and region. Results In women, doubling elaidic acid was associated with a decreased risk of weight loss (odds ratio (OR) = 0.69, 95% confidence interval (CI) = 0.55-0.88, p = 0.002) and a trend was observed with an increased risk of weight gain during the 5-year follow-up (OR = 1.23, 95% CI = 0.97-1.56, p = 0.082) (p-trend<.0001). In men, a trend was observed for doubling elaidic acid level and risk of weight loss (OR = 0.82, 95% CI = 0.66-1.01, p = 0.062) while no significant association was found with risk of weight gain during the 5-year follow-up (OR = 1.08, 95% CI = 0.88-1.33, p = 0.454). No association was found for saturated and cis-monounsaturated fatty acids. Conclusions These data suggest that a high intake of industrial trans fatty acids may decrease the risk of weight loss, particularly in women. Prevention of obesity should consider limiting the consumption of highly processed foods, the main source of industrially-produced trans fatty acids

Genetic deficiency of aldose reductase counteracts the development of diabetic nephropathy in C57BL/6 mice

National Science Foundation of China [30770490]; 973 Program of China [2009CB941601]; Science Planning Program of Fujian Province [2009J1010]; Natural Science Foundation of Fujian Province [2009J01180]; Fujian Provincial Department of Science and TechnoloThe aim of the study was to investigate the effects of genetic deficiency of aldose reductase in mice on the development of key endpoints of diabetic nephropathy. A line of Ar (also known as Akr1b3)-knockout (KO) mice, a line of Ar-bitransgenic mice and control C57BL/6 mice were used in the study. The KO and bitransgenic mice were deficient for Ar in the renal glomeruli and all other tissues, with the exception of, in the bitransgenic mice, a human AR cDNA knockin-transgene that directed collecting-tubule epithelial-cell-specific AR expression. Diabetes was induced in 8-week-old male mice with streptozotocin. Mice were further maintained for 17 weeks then killed. A number of serum and urinary variables were determined for these 25-week-old mice. Periodic acid-Schiff staining, western blots, immunohistochemistry and protein kinase C (PKC) activity assays were performed for histological analyses, and to determine the levels of collagen IV and TGF-beta 1 and PKC activities in renal cortical tissues. Diabetes-induced extracellular matrix accumulation and collagen IV overproduction were completely prevented in diabetic Ar-KO and bitransgenic mice. Ar deficiency also completely or partially prevented diabetes-induced activation of renal cortical PKC, TGF-beta 1 and glomerular hypertrophy. Loss of Ar results in a 43% reduction in urine albumin excretion in the diabetic Ar-KO mice and a 48% reduction in the diabetic bitransgenic mice (p < 0.01). Genetic deficiency of Ar significantly ameliorated development of key endpoints linked with early diabetic nephropathy in vivo. Robust and specific inhibition of aldose reductase might be an effective strategy for the prevention and treatment of diabetic nephropathy

Immunological, hematological, biochemical, and histopathological studies on cows naturally infected with lumpy skin disease

Aim: Lumpy skin disease (LSD) is an infectious viral disease of cattle caused by an LSD virus (LSDV) of the family Poxviridae characterized by skin nodules covering all parts of the body. There are many aspects of LSD remaining unknown, thus immunological, hematological, and biochemical parameters were estimated. Materials and Methods: During an outbreak of LSD in Sharkia governorate from Egypt, 211 cows aging (2-4 years) were examined clinically for the presence of LSD lesions during the period from July to November 2014. A total of 134 cows from those showed lesions suspected to be LSD. Results: Recorded clinical signs were pyrexia with the development of skin nodules of varying sizes which ranged from a few to several hundred sometimes coalesced together enlargements of the peripheral lymph nodes. Intracytoplasmic inclusion bodies were noticed in the histopathological examination. Immunological studies revealed a significant decrease of lymphocyte transformation rate, phagocytic % and killing % which was marked within 2 weeks postinfection. LSD resulted in non-significant in hemogram in 1st-2nd day post-infection while a macrocytic hypochromic anemia within 10-14th days post-infection. Leucopenia and lymphopenia were recorded 1st-2nd day post-infection while at 10-14th showed granulocytic leukocytosis. Biochemical analysis revealed hypoproteinemia, hypoalbuminemia, and hyperglobulinemia especially gamma globulins. The significant increase in serum alanine aminotransferase, aspartate aminotransferase activities, creatinine level, blood urea nitrogen and creatine phosphokinase Conclusion: LSDV infected cows in early stages revealed leucopenia. Immunosuppressive effect was pronounced later. In late stage revealed hemolytic anemia, leukocytosis and increase of serum CK, which could aid in diagnosis. Disturbance in liver and kidney function tests have been occurred
