Researchers identify candidate genes for histiocytoid cardiomyopathy

Researchers are closing in on a rare genetic disorder causing a heart condition in infants. Histiocytoid cardiomyopathy (HC) often causes sudden death before a child reaches 2 years of age. Gene analysis is helping to narrow the many theories surrounding the genetic basis of HC.

Scientists discover chemical compound that inhibits poxviruses from replicating

A team of scientists from Boston University School of Medicine (BUSM) have identified a novel compound that inhibits viruses from replicating. The findings, which are published online in the Journal of Virology, could lead to the development of highly targeted compounds to block the replication of poxviruses, such as the emerging infectious disease Monkeypox.

Mitochondrial dysfunction in tissue stem cells can cause aging-associated degeneration

Aging-related tissue degeneration can be caused by mitochondrial dysfunction in tissue stem cells. The research group of Professor Anu Suomalainen Wartiovaara at the University of Helsinki, with their collaborators in Max Planck Institute for Biology of Aging, Karolinska Institutet and University of Wisconsin, reported on the 3rd January in Cell Metabolism their results on mechanisms of aging-associated degeneration.

Hydrogen sulfide decreases manufacture of kidney scarring matrix proteins

Hydrogen sulfide, a gas notorious for its rotten-egg smell, may have redeeming qualities after all. It reduces high glucose-induced production of scarring proteins in kidney cells, researchers from The University of Texas Health Science Center San Antonio report in the Journal of Biological Chemistry.

Protein increases lean mass while extra calories increase fat mass

In a study conducted among 25 healthy individuals living in a controlled setting who were randomized to overconsumption of different levels of protein diets, those consuming the low-protein diet had less weight gain compared to those consuming normal and high protein diets, and calories alone, and not protein appeared to contribute to an increase in body fat, according to a study in the January 4 issue of JAMA.

Origin of osteoporosis could be directly linked to manganese depletion

The loss of manganese could mean that calcium does not stick to bones and could cause osteoporosis. This is the new theory put forward by researchers at the University of Castilla-La Mancha (UCLM) in Spain after studying deer antlers.

Combination of biomarkers indicates high risk of Alzheimer's in the future

Physician Oskar Hansson and his research group are studying biomarkers - substances present in spinal fluid and linked to Alzheimer's disease. The group has studied close to 140 people with mild memory impairment, showing that a certain combination of markers (low levels of the substance beta-amyloid and high levels of the substance tau) indicate a high risk of developing Alzheimer's disease in the future.
