Receptors for vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP) in the goose cerebral cortex were characterized using two approaches: (1) in vitro radioreceptor binding of [(125)I]-VIP, and (2) effects of peptides from the VIP/PACAP/secretin family on cyclic AMP formation. The binding of [(125)I]-VIP to goose cortical membranes was rapid, stable,...
Interferons are a group of antiviral cytokines acting as the first line of defense in the antiviral immunity. Here, we describe the antiviral activity of goose type I interferon (IFNα) and type II interferon (IFNγ) against duck plague virus (DPV). Recombinant goose IFNα and IFNγ proteins of approximately 20 kDa and 18 kDa, respectively, were expressed. Following DPV-enhanced green fluorescent p...
In comparison with hen egg white lysozyme, goose lysozyme is known to be aberrant in both its structure and its enzymatic behavior in the presence of polymers of N-acetylglucosamine or cell suspensions of Micrococcus luteus. Our chemical studies show, however, that like the hen enzyme, goose lysozyme has muramidase activity. At several pH levels ranging from 3.5 to 7.1 the goose enzyme liberate...
The goose is an economically important waterfowl that exhibits unique characteristics and abilities, such as liver fat deposition and fibre digestion. Here, we report de novo whole-genome assemblies for the goose and swan goose and describe the evolutionary relationships among 7 bird species, including domestic and wild geese, which diverged approximately 3.4~6.3 million years ago (Mya). In con...
Explaining and predicting animal distributions is one of the fundamental objectives in ecology and conservation biology. Animal habitat selection can be regulated by top-down and bottom-up processes, and is mediated by species interactions. Species varying in body size respond differently to top-down and bottom-up determinants, and hence understanding these allometric responses to those determi...
The fronting of the nucleus of the high back vowel /u/, as in the keyword GOOSE [21], is a sound change in progress that has been widely documented throughout the English-speaking world. This paper provides a detailed analysis of the GOOSE-fronting among a sample of 30 speakers from San Francisco, California, stratified according to age, gender, and ethnicity.
We report the draft genome sequence of goose dicistrovirus assembled from the filtered feces of a Canadian goose from South Lake Union in Seattle, Washington. The 9.1-kb dicistronic RNA virus falls within the family Dicistroviridae; however, it shares <33% translated amino acid sequence within the nonstructural open reading frame (ORF) from aparavirus or cripavirus.
Migratory birds are of particular interest for population genetics because of the high connectivity between habitats and populations. A high degree of connectivity requires using many genetic markers to achieve the required statistical power, and a genome wide SNP set can fit this purpose. Here we present the development of a genome wide SNP set for the Barnacle Goose Branta leucopsis, a model ...
Interferon γ receptor 1 (IFNGR1) and IFNGR2 are two cell membrane molecules belonging to class II cytokines, which play important roles in the IFN-mediated antiviral signaling pathway. Here, goose IFNGR1 and IFNGR2 were cloned and identified for the first time. Tissue distribution analysis revealed that relatively high levels of goose IFNγ mRNA transcripts were detected in immune tissues, inclu...
مطالعه اثرات شستشو، مدت زمان و دمای نگهداری بر خصوصیات جوجه کشی تخم غازهای بومی استان آذربایجان شرقی
The aim of this study was to investigate the effects of washing, storage time and storage temperature on hatchability and post- hatch growth of East Azarbaijan goose eggs. A total of 144 clean goose eggs were randomly selected from Malekan goose research station, East Azarbaijan and were asigned randomly for each treatment. There were 12 treatments in a factorial arrangement 2×3×2 based on...
