pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Anti Microbial Resistance Profile of E. coli isolates From Tropical Free Range Chickens [PDF]

, 2005
Normal intestinal flora of humans and animals constitute enormous reservoir of resistance genes for potentially pathogenic bacteria and may serve as major indictors of selection pressure exerted by anti-microbial use in a given population.

Seroprevalence of Neospora caninum infection in free ranging chickens (Gallus domesticus) [PDF]

Journal of Parasitic Diseases, 2014
Recently chickens are considered as an important intermediate hosts for Neospora caninum. Free range chickens expose to infection with N. caninum oocysts because they feed from the ground therefore they could be a good index of the environmental contamination. We studied N. caninum infection in free range chickens by serological.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Effect of breed suitability, system design and management on welfare & performance in traditional & organic poultrymeat (OF0153) [PDF]

, 2002
Background Over the past fifty years broiler production accounted for almost all of the meat chickens produced in the UK. As a result, only broiler hybrids were available for use by UK producers, and these were not thought to be suited for use in some ...

The pyruvate generator is a common phenomenon in mitochondria from different rat and mouse brain regions

FEBS Letters, EarlyView.
The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

Predation in Organic and Free-Range Egg Production

Animals, 2020
On organic and free-range poultry farms, a free-range is provided for animal welfare reasons. However, farmers report sightings of birds of prey and sometimes foxes or other predators within the free-range areas.

Improved texture of breast meat after a short finishing feeding period of broilers in an organic free-range system [PDF]

, 2013
In order to develop an organic broiler product with high ethical value, high meat quality and based on locally produced feed, we tested if a long period without high quality protein feed followed by a finishing period with a high quality protein ration ...

Heat Stress and feeding strategies in meat-type chickens [PDF]

, 2011
Heat stress can induce hyperthermia in poultry. A reduction in heat load can be achieved by increasing the possibilities for dissipation, decreasing the level of heat production or by changing the thermal production pattern within a day.
