How hepatitis B and delta viruses establish infection of liver cells
Science Daily - 18 Jun 2019 20:35
Researchers have developed a new, scalable cell culture system that allows for detailed investigation of how host cells respond to infection with hepatitis B (HBV) and delta virus (HDV).
Inhaling air pollution-like irritant alters defensive heart-lung reflex for hypertension
Science Daily - 18 Jun 2019 20:35
Using a rat model for high blood pressure (hypertension), a common chronic cardiovascular condition, researchers found that preexisting hypertension altered normal reflexes in the lungs to affect autonomic regulation of ...
Biology of leptin, the hunger hormone, revealed
Science Daily - 18 Jun 2019 19:31
New research offers insight into leptin, a hormone that plays a key role in appetite, overeating, and obesity. The findings advance knowledge about leptin and weight gain, and also suggest a potential strategy for develo...
Gene linked to cannabis abuse
Science Daily - 18 Jun 2019 18:48
New research shows that a specific gene is associated with an increased risk of cannabis abuse. The gene is the source of a so-called nicotine receptor in the brain, and people with low amounts of this receptor have an i...
