Methionine Regulates Antitumour Function of CD8+ T Cells Through Polyamine Synthesis

Immunology, EarlyView.
Methionine restriction in vitro enhances CD8+ T cell effector function by suppressing polyamine synthesis and progressively induces the co‐expression of PD‐1 and TIM‐3. Consistently, sustained dietary methionine restriction diminishes the efficacy of adoptive T cell therapy (ACT) and promotes the expression of terminal exhaustion‐associated markers ...

Genetic Control of Canalization for Twinning Rates in Polypay and Rambouillet Sheep Using Threshold or Double Hierarchical Generalized Linear Models

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In most sheep production systems, the ideal scenario is for every ewe to lamb and successfully raise twins. However, selection for increased number of lambs born (NLB) is often accompanied by a higher incidence of triplet and higher‐order births, which increases management challenges and producer reluctance to intensify selection for this ...

Estimating Patagonian toothfish (Dissostichus eleginoides) length at first maturity from their age, sex and temperature experience around South Georgia

Journal of Fish Biology, EarlyView.
Abstract Patagonian toothfish (Dissostichus eleginoides) are a long‐lived, slow‐growing deep‐sea species endemic to the Southern Hemisphere and the focus of longline fisheries managed to ensure sustainable exploitation. Managing the fisheries relies on accurate stock assessments that include pertinent biological and exploitation processes.

Modelling relationships between juvenile brown trout (Salmo trutta L.) density and landscape characteristics: Integration of electrofishing data and spatial data to assess population status

Journal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta L.) are ecologically and economically important, but like many salmonids their populations are declining. Trout exhibit a high level of phenotypic plasticity, ranging from freshwater residency to anadromy. This complexity causes problems for assessment and constrains application of adult catch‐based assessment methods
