Study reveals role of circadian rhythms in regenerative capacity of skin stem cells

The investigation reveals the role of the daily biological clock (circadian rhythms) in the regenerative capacity of skin stem cells. Disruption of this rhythm results in premature tissue ageing and a greater predisposition to the development of skin tumours. The

Stem cell markers can aid in determining origin of pediatric sarcomas

The authors of a report in the current issue of the journal Pediatric and Developmental Pathology sought to use stem cell markers as an aid in determining the cell of origin. The expression of stem cell-associated proteins shows differences that can help identify how the tumors evolve. Eighty-one tumors were analyzed, all diagnosed in patients under 18 years old.

Mathematical model accurately predicts horizontal gaze movements of eye

In one respect, handling a computer mouse is just like looking in the rearview mirror: well established movements help the brain to concentrate on the essentials. But just a simple gaze shift to a new target bears the possibility of an almost infinite number of combinations of eye and head movement: how fast do we move eye and head? How much does the eye rotate, how much the head? Until now, it was unclear why the brain chooses a particular movement option from the set of all possible combinations.

POPG inhibits influenza infections in cell cultures and mouse models

A natural lipid in the fluid lining the lungs inhibits influenza infections in both cell cultures and mouse models, according to researchers at National Jewish Health. These findings, combined with previous studies demonstrating effectiveness against respiratory syncytial virus, suggest that the molecule, known as POPG, may have broad antiviral activity.
