Exogenous histamine decreases food intake and injection of H-1 antagonists increases food intake in rats. Previous work has focused on the effect of relatively large doses of histamine on eating behavior, and have not measured the effect of histamine on postprandial satiety behaviors. This work measures the effect of small and large doses of histamine and investigates the effects of an H-1 rece...

in this study, 90 internal organ samples of poultry with symptoms of colibacillosis were obtained from maragheh poultry farms in east azerbaijan, iran. in total, 70 bacterial isolates were confirmed as escherichia coli (e. coli) strains using standard biochemical tests, and antibiotic sensitivity was determined by the disk diffusion method. antibiotics used in this study included ampicillin, pe...

Anthelmintic resistance has been increasingly reported in cattle worldwide over the last decade, although reports from Europe are more limited. The objective of the present study was to evaluate the efficacy of injectable formulations of ivermectin and moxidectin at 0.2 mg per kg bodyweight against naturally acquired gastro-intestinal nematodes in cattle. A total of 753 animals on 40 farms were...

AIM This study was conducted to investigate the occurrence of pathogenic Escherichia coli and Salmonella species in retail raw table eggs sold for human consumption in Enugu State and to determine the resistance of these pathogens to antimicrobials commonly used in human and veterinary practices in Nigeria. MATERIALS AND METHODS A total of 340 raw table eggs comprising 68 composite samples (5...

625 IRAQ, Afghanistan, Kosovo, Bosnia, Somalia, Mozambique, Indonesia – all countries that have suffered or are currently suffering from the effects of conflict or natural disaster, and all countries where veterinary expertise has been required. While media images from such areas primarily focus on the human cost, livestock and draught animals are often an essential part of the lives of the peo...

1. Proof. (a) Let x ∈ [0, 1] and δ > 0, we want to show that there exist n such that nλ mod 1 ∈ (x−δ, x+δ), for which it suffices to show that there exists n0 and y ∈ (−δ, δ) such that n0λ ≡ y (mod 1). Then take n to be an appropriate multiple of n0. To prove the reduced proposition, choose m such that 10−m < δ. Note that there exist n1 < n2 such that (n1λ mod 1) and (n2λ mod 1) have the same f...

Fecal samples from 335 dairy farm residents and 1458 cattle on 80 farms were tested for Vero cytotoxin (VT)-producing Escherichia coli (VTEC). Residents were also tested for antibodies to VT1 and O157 lipopolysaccharide (LPS). Residents and cattle on farms with VTEC-positive persons or E. coli O157:H7-positive cattle were retested. Twenty-one persons (6.3%) on 16 farms (20.8%) and 46% of cattle...

Imprinted genes show differential expression between maternal and paternal alleles as a consequence of epigenetic modification that can result in ‘parent-of-origin’ effects on phenotypic traits1. There is increasing evidence from mouse and human studies that imprinted genes may influence behavior and cognitive functioning2. Previous work in girls with Turner syndrome (45,XO) has suggested that ...
