Thyroid hormone metabolism in poultry [PDF]

Biotechnologie, Agronomie, Société et Environnement, 2000
Thyroid hormone (TH) receptors preferentially bind 3.5,3'-triiodothyronine (T3). Therefore the metabolism of thyroxine (T4) secreted by the thyroid gland in peripheral tissues, resulting in the production and degradation of receptor-active T3, plays a ...

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

FEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

The Chicken and the Egg

, 1993
“Which came first, the chicken or the egg?” For all its innocence, this is a question which, as this paper will show, obliges one to think deeply about the terms in which one ultimately seeks to explain biological systems. “A hen is only the egg’s way of making another egg”, in Butler’s (1878)1 apt phrase, sums up the view that organisms can most ...

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

FEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Backyard chickens in the United States: a survey of flock owners.

Poultry Science, 2014
Although it has become increasingly popular to keep backyard chickens in the United States, few studies have provided information about these flocks. An online survey of backyard chicken owners was conducted, advertised through Master Gardeners' websites,

Guiding AlphaFold to predict how Munc13‐1 opens Syntaxin‐1

FEBS Open Bio, EarlyView.
The syntaxin‐1 Habc‐domain (orange), linker (pink) and SNARE motif (yellow) form a closed conformation that binds to Munc18‐1 (violet) and is opened by the Munc13‐1 MUN domain (cyan) to form the SNARE complex that triggers neurotransmitter release.

Progress from Chicken Genetics to the Chicken Genome

Poultry Science, 2006
The chicken has a proud history, both in genetic research and as a source of food. Here we attempt to provide an overview of past contributions of the chicken in both arenas and to link those contributions to the near future from a genetic perspective. Companion articles will discuss current poultry genetics research in greater detail.
