The sirtuin family of histone deacetylases (HDACs) was named after their homology to the Saccharomyces cerevisiae gene silent information regulator 2 (Sir2). In the yeast, Sir2 has been shown to mediate the effects of calorie restriction on the extension o ...
Body mass and composition reflect the combined effects of three processes: energy intake, energy partitioning (storage), and energy expenditure. Energy is released from food as it is combusted to carbon dioxide and water, and is expended as heat and work w ...
A novel approach for indirect biomass detn. in case of non-const. specific metabolic rates is reported. Specific glucose consumption rate was detd. during a first calibration culture for both free suspended and immobilized cells. It was expressed as a line ...
Animal cell (Chinese Hamster Ovary) concn. was detd. online in a packed bed process using dielec. spectroscopy. This enabled the evaluation of the effect of temp. on specific metabolic rates during 3 mo of continuous culture. The effect of low cultivation ...
The present invention is directed to methods of treating a human for a variety of conditions by administering an agonist of the G protein coupled receptor TGR5. In addition, the invention includes methods for determining whether a test compound is likely t ...
The role of the tumor suppressor retinoblastoma protein (pRb) has been firmly established in the control of cell cycle, apoptosis, and differentiation. Recently, it was demonstrated that lack of pRb promotes a switch from white to brown adipocyte different ...
Oxygen is a key substrate in animal cell metab. and its consumption is thus a parameter of great interest for bioprocess monitoring and control. A system for measuring it based on an oxygen balance on the liq. phase was developed. The use of a gas-permeabl ...
Rehydration in the triatomine bug Rhodnius prolixus (Stal) is dependent on the blood meal, and water balance regulation is crucial for survival of starving bugs. In an experimental arena with zones at different climatic conditions, starved R. prolixus nymp ...
Successful behavior requires contextual modulation of learned "programs", that is, the retrieval or nonretrieval (inhibition) of behavioral elements depending on situative context. Here we report neural correlates of these elementary aspects of behavior as ...
We have explored the effects of two members of the p160 coregulator family on energy homeostasis. TIF2-/- mice are protected against obesity and display enhanced adaptive thermogenesis, whereas SRC-1-/- mice are prone to obesity due to reduced energy expen ...
