Seoul virus outbreak associated with home-based rat-breeding facilities

Experts from CDC are working with the Illinois Department of Health and the Wisconsin Department of Health Services to investigate cases of Seoul virus infections among eight people who worked at several rat-breeding facilities in the two states. Seoul virus is not commonly found in the United States, though there have been several reported outbreaks in wild rats. This is the first known outbreak associated with pet rats in the United States.

Tracking movement of immune cells identifies key first steps in inflammatory arthritis

Using a novel approach for imaging the movement of immune cells in living animals, researchers have identified what appear to be the initial steps leading to joint inflammation in a model of inflammatory arthritis.

Researchers unlock mechanism of drug resistance in aggressive breast cancer

Scientists report findings of how triple negative breast cancer cells are able to bypass treatment with trametinib, a U.S. Food and Drug Administration-approved drug that belongs to a class of commonly used anti-cancer drugs called kinase inhibitors. The researchers also reported findings from laboratory models of breast cancer testing a potential treatment approach that could prevent the onset of resistance.

New genetic engineering technique could help design, study biological systems

A new technique will help biologists tinker with genes, whether the goal is to turn cells into tiny factories churning out medicines, modify crops to grow with limited water or study the effects of a gene on human health. The technique allows scientists to precisely regulate how much protein is produced from a particular gene. The process is simple yet innovative and, so far, works in everything from bacteria to plants to human cells.

Number of women who take maternity leave has stalled

The number of U.S. women taking maternity leave has not changed in 22 years despite factors that suggest it should be increasing, a new study found. During the same time, the number of fathers taking paternity leave more than tripled.

Think binge drinking is safer for your liver than regular heavy drinking? Think again

Alcoholic liver disease (ALD) occurs on a spectrum of severity. The majority of people who drink excessively develop a fatty liver, which though often symptom free, can progress to a state of inflammation, fibrosis, and cell death that can be fatal. Little is known about liver disruption that may occur in problem drinkers who are not alcohol dependent. To help understand the development of ALD, this study used a rodent model to examine differences in liver damage between binge drinkers and heavy drinkers.

New, old science combine to make faster medical test

Magnetic nanoparticles are coated with an antibody, then aligned in formation within a magnetic field and tallied under laser optics. The result could lead to speedy diagnoses for infectious diseases.

Study discusses model for understanding nutrition and brain development

For nearly a decade, researchers have studied the piglet as a translational model to understand which aspects of early brain development are affected by nutrition interventions. In a recent review article, investigators provide background for the work they do with nutrition and neurodevelopment using the piglet as a model.

Team uncovers cellular responses to bird flu vaccine

New research eavesdrops on gene expression in human immune system cells before and after vaccination against bird flu, exposing cellular responses associated with a vaccine constituent called AS03, short for adjuvant system 03. Using massive computation, the investigators pursue a systems biology approach, providing a new wealth of detail about vaccine responses and data for the generation of new hypotheses.

Type 1 diabetes linked to gut inflammation, bacteria changes

People with Type 1 diabetes exhibit inflammation in the digestive tract and gut bacteria, a pattern that differs from individuals who do not have diabetes or those who have celiac disease, according to a new study.
