Choice of grazed herbage or maize silage by lactating dairy cows: influence of sward height and concentrate level Preferência por pastagem ou silagem de milho por vacas leiteiras em lactação: influência da altura do pasto e do nível de concentrado

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2010
The preference of lactating dairy cows for grazed herbage or maize silage (MS), simultaneously offered ad libitum in the field, was examined at two sward heights (SH 4-6 and 8-10cm) and two concentrate levels (CL 0 and 6kg day-1) in a 2x2 factorial ...

Proteasome inhibitor, ixazomib prevents topoisomerase‐I degradation and reverses irinotecan resistance in colorectal cancer

Molecular Oncology, EarlyView.
Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.

Estrutura da pastagem e padrões de desfolhação em capim-mombaça em diferentes alturas do dossel forrageiro Sward structure and defoliation patterns in mombaçagrass according to different canopy heights

Revista Brasileira de Zootecnia, 2005
Com o objetivo de avaliar o padrão de desfolhação em pastagens de capim-mombaça (Panicum maximum, Jacq.), novilhas leiteiras da raça HPB foram submetidas, em testes de pastejo, a cinco alturas de dossel (60, 80, 100, 120 e 140 cm), em um delineamento ...

Foraging ecology of fall-migrating shorebirds in the Illinois River valley. [PDF]

PLoS ONE, 2012
Populations of many shorebird species appear to be declining in North America, and food resources at stopover habitats may limit migratory bird populations.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Prey selection by an apex predator: the importance of sampling uncertainty. [PDF]

PLoS ONE, 2012
The impact of predation on prey populations has long been a focus of ecologists, but a firm understanding of the factors influencing prey selection, a key predictor of that impact, remains elusive.

Cannabimimetic phytochemicals in the diet - an evolutionary link to food selection and metabolic stress adaptation? [PDF]

, 2017
The endocannabinoid system (ECS) is a major lipid signalling network that plays important pro-homeostatic (allostatic) roles not only in the nervous system but also in peripheral organs.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Diet and heavy metal uptake by two top predator species in the Tees Estuary [PDF]

, 2006
The key aim of the thesis was to estimate metal uptake and its seasonal variation from the diet by two predators from the Tees Estuary, harbour seals, Phoca vitulina and cormorants, Phalacrocorax carbo.
