Gene variants influence size of brainstem, other structures

Researchers have found a link between 48 common genetic variations and the size of the brainstem and other subcortical structures deep within the brain. These structures control a wide array of functions ranging from learning ...

Failure of mitochondrial quality control causes heart disease

Mutations in the gene that encodes a protein called adenine nucleotide translocator (ANT) cause a variety of conditions, such as heart disease and weakness of the eye muscles, but the underlying mechanism of how these mutations ...

Scientists shed light on how brains turn pain up or down

Pain perception is essential for survival, but how much something hurts can sometimes be amplified or suppressed: for example, soldiers who sustain an injury in battle often recall not feeling anything at the time.

Cardiology

Less inflammation = better healing

Myocardial infarction (MI), commonly called heart attack, remains a leading cause of mortality and morbidity worldwide, raising an urgent need for novel therapies.

Limiting mealtimes may increase exercise motivation

Limiting access to food in mice increases levels of the hormone, ghrelin, which may also increase motivation to exercise, according to a study published in the Journal of Endocrinology.

Faulty signalling pathway linked to congenital heart condition

A congenital heart condition known as left ventricular non-compaction (LVNC), which occurs when muscly projections in the embryonic heart fail to transform into compact heart muscle, could be caused by signaling defects, ...
