Study reveals how dengue virus replicates without triggering the body's defenses

A new study reveals how dengue virus manages to reproduce itself in an infected person without triggering the body's normal defenses. Duke researchers report that dengue pulls off this hoax by co-opting a specialized structure within host cells for its own purposes, like a lazy roommate sneaking bits of his laundry into the communal wash.

Unhealthy diet makes the body's defenses more aggressive in the long term

The immune system reacts similarly to a high fat and high-calorie diet as to a bacterial infection. This is shown by a recent study led by the University of Bonn.

New TSRI study uncovers workings of first potential treatment for Marburg virus

With a mortality rate of up to 88 percent, Marburg virus can rip through a community in days. In 2005, an outbreak of Marburg virus struck a pediatric ward in the country of Angola. With no treatment available, doctors struggled to help as the virus killed 329 of 374 infected patients.

New study discovers key brain circuit implicated in social behavior

A new study by researchers at Roche in Basel, Switzerland has identified a key brain region of the neural circuit that controls social behavior. Increasing the activity of this region, called the habenula, led to social problems in rodents, whereas decreasing activity of the region prevented social problems.

Human cardiac-muscle patches improve recovery from heart attack injury

Large, human cardiac-muscle patches created in the lab have been tested, for the first time, on large animals in a heart attack model. This clinically relevant approach showed that the patches significantly improved recovery from heart attack injury.

Clinical study investigates lifestyle biomarkers in prostate cancer survivors

Advanced glycation end products, which have been linked to many chronic diseases, including diabetes, cardiovascular disease and cancer, build up in the body from birth due to normal metabolism but are often higher in those eating the high-fat, high-sugar, highly processed foods characteristic of the Western diet.

Study identifies enzyme that regulates inflammation and metabolism in fat tissue

The human body has two primary kinds of fat--white fat, which stores excess calories and is associated with obesity, and brown fat, which burns calories in order to produce heat and has garnered interest as a potential means of combating obesity.

Researchers find evidence for genetic relationship between epileptic seizures and depression

From the time of Hippocrates, physicians have suspected a link between epilepsy and depression. Now, for the first time, scientists at Rutgers University-New Brunswick and Columbia University have found evidence that seizures and mood disorders such as depression may share the same genetic cause in some people with epilepsy, which may lead to better screening and treatment to improve patients' quality of life.
