Insights into a long life without cancer: The case of the bowhead whale

Molecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Formulação com aminoácidos totais ou digestíveis em rações com níveis decrescentes de proteína bruta para frangos de corte de 21 a 42 dias de idade Total and digestible amino acids formulation in diets with decreasing levels of crude protein for broilers from 21 to 42 days of age

Revista Brasileira de Zootecnia, 2008
Foram realizados dois experimentos para avaliar a formulação de rações para frangos de corte com redução do nível de proteína bruta (PB) e suplementadas com aminoácidos sintéticos, formuladas com base nos aminoácidos totais - AAT (experimento 1) ou ...

Molecular cancer prevention: Intercepting disease

Molecular Oncology, EarlyView.
Oncological practice must evolve, from treating established tumours to proactive cancer interception before clinical manifestation. This will require mechanistic insight into tumour initiation, validated biomarkers of early disease development and redesigned clinical trials, enabling cancer interception to become a core pillar of oncology with the ...

Níveis de lisina digestível em rações para frangos de corte de 22 a 42 dias de idade, mantidos em ambiente de termoneutralidade Requirements of dietary digestible lysine for broilers from 22 to 42 days old on thermoneutral environment

Revista Brasileira de Zootecnia, 2005
Dois ensaios foram conduzidos para se avaliarem os efeitos de níveis de lisina digestível em rações, mantendo ou não a relação aminoacídica, sobre o desempenho de frangos de corte dos 22 aos 42 dias, criados em ambiente de termomeutralidade. No ensaio 1,

Ideal Glasses and Protein Network Dynamics

, 2005
Quantitative topological analogies between the flexibilities of optimized inorganic glasses, small biological molecules, and proteins suggest that mean field estimates of internal stress are useful in identifying mechanisms supporting living materials and their enzymatic products.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Alcohol‐induced altered glycans in human tracheal epithelial cells promote bacterial adhesion

FEBS Open Bio, EarlyView.
Alcohol induces altered glycans to promote bacteria adhesion. Heavy alcohol drinking is known to increase the risk of bacterial pneumonia. However, the link between alcohol levels and risk of infection remains underexplored. Recently, we found that alcohol induced α2‐6sialo mucin O‐glycans in human tracheobronchial epithelial cells, which mediated the ...
