this study was conducted to detect the presence ofseja gene among salmonella enteritidis isolates from poultry sources by polymerase chain reaction (pf'r) and evaluate its potential as diagnostic and epidemiological tools. thirty salmonella isolates from poultry sources: broilers. broiler breeders, layers, hatcheries, and poultry abattoirs were investigated. upper and forward primers were ...

Tears contain many different proteins which can act as endogenous fluorescence biomarkers. This biological fluid is not used in clinical practice yet. The aim of this work is an experimental analysis of final fluorescence intensity of tear ́s proteins from right and left eye of healthy subjects by synchronous fluorescence fingerprint. Tears of the healthy subjects exhibited the final protein flu...

Background Adherence to treatment, healthy lifestyle, physical activities, smoking, diet, and salt intake are important factors to control for an effective decrease in blood pressure (BP) values for patients diagnosed with essential hypertension (HT). The aim of this work was to study the adherence to antihypertensive treatment and factors predicting this behavior in Lebanese patients. In addit...

BACKGROUND The blood pressure (BP) increase with age is well documented in adults and children. However, in the pediatric age group, body size is the most important determinant of age-related BP increases. The aim of the present analysis was to investigate the relationships between age, gender, and body size and BP in children. METHODS To this purpose, data were analyzed from 4,514 prepuberta...

RecA-mediated recombination requires regions of homology between donor and recipient DNA for successful integration. This paper investigates the effect of the relationship between the length of gene-sized inserts (434, 733, 2228 and 2400 bp) and flanking sequence homology (100 - ca. 11 000 bp) on transformation frequency in Acinetobacter baylyi strain BD413. Both insert size and size of the hom...
