Evolutionary temperature compensation of carbon fixation in marine phytoplankton [PDF]

, 2020
The efficiency of carbon sequestration by the biological pump could decline in the coming decades because respiration tends to increase more with temperature than photosynthesis.

Consequences of simulated microgravity in neural stem cells: biological effects and metabolic response. [PDF]

, 2015
Objective: Microgravity was often shown to cause cell damage and impair cell cycle in a variety of biological systems. Since the effects on the neural system were poorly investigated, we aimed to gain insight into how biological processes such as cell ...

Metabolic effects of diets differing in glycaemic index depend on age and endogenous GIP [PDF]

, 2009
Aims/hypothesis High- vs low-glycaemic index (GI) diets unfavourably affect body fat mass and metabolic markers in rodents. Different effects of these diets could be age-dependent, as well as mediated, in part, by carbohydrate-induced stimulation of ...
