Are forest disturbances amplifying or canceling out climate change-induced productivity changes in European forests?

Recent studies projecting future climate change impacts on forests mainly consider either the effects of climate change on productivity or on disturbances. However, productivity and disturbances are intrinsically linked because 1) disturbances directly affect forest productivity (e.g.

Aging Effects of Ryanodine Receptor Variants Corresponding to Human Myopathic Mutations.

Delaying the decline in skeletal muscle function will be critical to better maintenance of an active lifestyle in old age. The skeletal muscle ryanodine receptor, the major intracellular membrane channel through which calcium ions pass to elicit muscle contraction, is central to calcium ion balance and is hypothesized to be a significant factor for age-related decline in muscle function. The nematode is a key model system for the study of human aging, and strains were generated with modified ryanodine receptors corresponding to human myopathic variants linked with malignant hyperthermia and related conditions.

Association between weekend admission and mortality for upper gastrointestinal hemorrhage: an observational study and meta-analysis.

Higher in-hospital mortality for weekend vs. weekday admissions has been described. We performed a retrospective study and accompanying meta-analysis to examine the association between weekend admission for upper gastrointestinal hemorrhage (UGIH) and in-hospital mortality.
