effect of probiotic (clostat) levels on the performance and immune response of heat stressed broilers, was evaluated in a completely randomized design on 144 day-old male ross broiler chicks with four treatments and four replicates (nine birds each). experimental diets were consisted in four levels of probiotic (0, 0.05, 0.1 and 0.2). birds were raised under normal condition till 25 days of age...

Eight virulence factors associated with uropathogenic Escherichia coli (UPEC) were investigated in 204 clinical isolates of E. coli recovered from urine cultures at counts ≥10(5). The bacteria were classified into two groups according to the number of leukocytes in urine samples from which they were isolated: group I ≤8 leukocytes/hpf, 104 strains; group II >8 leukocytes/hpf, 100 strains....

Background: The need for simulation in minimally invasive surgery (MIS) has been established. Uptake of simulator training remains poor however. This study quantifies the global availability of simulation equipment, how it is currently used and clinicians’ aspirations for the future, including the emerging phenomenon of pre-operative rehearsal/warm-up. Methods: An online survey was distributed ...

The Nation's spending for health in fiscal year 1976 reached $139.3 billion, or $638 per person, according to preliminary figures. This total was 14 percent higher than the $122.2 billion spent for health in 1975. In the 2 years since price controls on the health industry were lifted, expenditures have risen $33.0 billion (31 percent). During this period, the economy has grown at a relatively s...

Recent protest movements brought attention to the one percent, a segment of the population that is critical to understanding inequality and social mobility but that attracts relatively little research attention. In this article, I survey current research on the one percent in the United States. I distinguish income from wealth and show that both are very concentrated but that the concentration ...

the current study was designed to estimate the frequency of igf-i gene 1 polymorphism and investigate if their polymorphisms have association with biometric traits in moghani sheep by pcr-sscp method. for this purpose, a number of 100 sheep were randomly chosen from moghani sheep jafarabad, moghan breeding station that located in ardabil state and blood samples were collected from the left jugu...

The flux of teniposide (VM-26) across the cell membrane was compared for L1210 cells, nine VM-26-resistant L1210 sublines, and three partially revertant lines. The nine resistant sublines were maintained in medium with VM-26. A "zero-time," temperature-independent binding of VM-26 to cells, attributable to adsorption on the cell membrane or to solvation in the membrane, varied independently of ...
