Abstract: The aim of this research was to investigate essential groups of amino acids and effect of amino acid supplementation. P. ACIDILACTICI culture was grown in chemically defined medium (CDM) with initial pH 6.35 and at 30°C. To minimize the number of experiments, the experimental design was based on grouping the metabolic amino acid pool. The selected amino acid groups were the following: a) phenylalanine and tyrosine; b) lysine, methionine, isoleucine; c) leucine and valine and d) histidine. The concentration of each…

Abstract: Hepatitis B virus (HBV) infection develops in forms from asymptomatic carrier to cirrhosis. There are several studies examining the quality of life of patients with HBV in literature. However, only two studies have investigated the psychiatric morbidity in hepatitis B patients. In this study, we evaluated psychiatric morbidity and quality of life in inactive HbsAg carriers. This case-controlled study was performed among 26 healthy volunteers as control group and 31 inactive HbsAg carriers. Seven (22.5%) of our Hepa…

Abstract: A marine exopolysaccharide (EPS) producing bacterium was isolated from a sponge sample at about 16 m depth in red sea (Huraghada, Egypt). Phenotypic characterization demonstrated that, the bacterium is a gram negative rod motile by means of single polar flagellum, showing wide range of carbohydrate utilization. Phylogenetic analysis based on 16S Ribosomal deoxyribonucleic acid (rDNA) sequence revealed 99% homology with PSEUDOALTEROMONAS sp., accordingly the name PSEUDOALTEROMONAS sp. AM was proposed. Maximum EPS pr…

Abstract: This research was aimed to determine the incidence and antibiotic susceptibility profile of bacteria isolated from mobile phones of food handlers in Birnin Kebbi, Kebbi state Nigeria, using aseptic swab technique. Hundred swab samples from mobile phones of food handlers were collected. Bacteria Isolated were enumerated using pour plate method and overall mean aerobic mesophilic bacterial counts of 2.70x106CFU/ml was obtained. Bacterial isolates (n=111) belonging to three genera; S. aureus (n=88) Escherichia coli (n…

Abstract: Lactic acid bacteria (LAB) commonly used in food, as starter cultures are known to produce antimicrobial substances such as bacteriocins and have great potential as food bio-preservatives. Yogurt is a probiotic dairy product having Lactobacillus bulgaricus as natural source for fermentation. The aim of this study was to determine the antimicrobial activity of bacteriocin, produced by Lactobacillus bulgaricus isolated from yogurt and tested against pathogenic organisms. The identification of the culture was based on…

Abstract: Bioactive substances from marine biota have been found useful as special tools in pharmacological and biomedical research. In the present study, the in vitro antimicrobial activity of crude methanolic extracts of six species of cephalopods (Sepia kobiensis, Sepiella inermis, Sepioteuthis lessoniana, Octopus aegina, Octopus aerolatus, Octopus dollfusi) from Cuddalore (Southeast coast of India) was studied. The antimicrobial activity was screened against 10 species of clinically isolated human pathogenic bacteria nam…

Abstract: These days one of the real problems that cause the prejudice-economy in animal farms yearly is parasitic disease. For that reason and to prevent these problems the use of antiparasitic drugs is necessary. Ivermectin is a broad spectrum antiparasitic agent and is in different dosage forms such as injection, oral and pour-on. The aims of this study was to evaluate the efficacy of ivermectin pour-on administration against natural Nematodirus spathiger nematode infections in cattle and also to determine the prevalent r…

Abstract: Chronic heart failure (CHF) is characterized by diminished cardiac output and pooling of blood in the venous system. Using transcriptome data, we constructed a regulation network to identify the potential genes that related to heart failure. In the network, some of transcription factors and its’ target genes have been proved to be related to heart failure in previous study. According to the regulation network, we found some new transcription factors and target genes, which have not been proved to be directly relate…

Abstract: In the present study, structural properties of C7 Si5 Ge3 cluster and interaction between this cluster and vitamin C have been studied extensively utilizing density functional theory (DFT) employing B3LYP exchange correlation. Nuclear magnetic resonance (NMR) properties are calculated by using density functional method (B3LYP) with 6-31G, 6-311G* and cc-pvdz as basis sets. Also natural bond orbital (NBO) analysis has been performed for C7 Si5 Ge3 cluster and C7 Si5 Ge3 inside vitamin C. Our results indicate that vi…
