In ovo delivery of prebiotics and synbiotics in chickens allows for the development of intestinal microflora prior to hatching, which boosts their robustness. The goal of this study was to determine the transcriptomic profile of the spleen (S), cecal tonsils (CT), and large intestine (LI) of adult chickens injected with prebiotics and synbiotics in ovo. On day 12 of embryo development, incubati...

Genetic and receptor interference data have indicated the presence of one or more cellular receptors for subgroup B, D, and E avian leukosis viruses (ALV) encoded by the s1 allele of the chicken tvb locus. Despite the prediction that these viruses use the same receptor, they exhibit a nonreciprocal receptor interference pattern: ALV-B and ALV-D can interfere with infection by all three viral su...

S-type pyocins are bacteriocins produced by Pseudomonas aeruginosa isolates to antagonize or kill other strains of the same species. They have a modular organization comprising a receptor-binding domain recognizing a surface constituent of the target bacterium, a domain for translocation through the periplasm, and a killing or toxic domain with DNase, tRNase, or pore-forming activity. Pyocins S...

objective(s): asthma results from the interaction between genetic and environmental factors. adam33 gene on chromosome 20p13 is associated with asthma and airway hyperresponsiveness. materials and methods: this is a case-control study, where four snps s1 (rs3918396), t1 (rs2280091), t2 (rs2280090), v4 (rs2787094) of adam33 gene have been assessed in patients with allergic asthma and normal cont...

P-450c21, a cytochrome P-450 enzyme [steroid 21-monooxygenase (steroid 21-hydroxylase), EC 1.14.99.10], mediates the 21-hydroxylation of glucocorticoid and mineralocorticoid hormones in the adrenal gland. The complete sequence of a bovine P-450c21 gene shows it is 3447 base pairs long and contains 10 exons. The intron/exon organization and encoded amino acid sequence indicate that P-450c21 repr...

SARS-CoV-2, causing the COVID-19 pandemic, has claimed millions of lives worldwide. SARS-CoV-2 a high mutation rate in its genome, resulting thousands variants. The success is attributed to S gene, which encodes spike protein that interacts directly with hACE2. Mutations this gene are known increase transmission and ability escape immune system virus. This study focused on analyzing nucleotide ...
