Yerkes researchers create animal model of chronic stress

Researchers at Yerkes National Primate Research Center created an animal model to study the effects of chronic stress on behavior, physiology, and reproduction. Corticotropin-releasing factor (CRF) is a key neurohormone involved in stress response, and its increased expression is linked to anxiety, depression, and infertility.

DNA editing tool flips its target

Scientists at Emory University School of Medicine have identified a crucial protein called UHRF1 that acts like a bookmark to maintain the correct pattern of DNA methylation. This process is essential for normal development and preventing cancer, as alterations in methylation patterns can lead to gene silencing at the wrong times.

Respiratory illnesses and dog bites a concern for travelers to China for 2008 Olympics

Respiratory illnesses, such as the common cold and pneumonia, were the primary diagnoses for travelers in China. Dog bites were also a significant concern, with 400 reported cases over 10 years, leading to rabies vaccination needs. Travelers can minimize risks by planning ahead, using common sense, and taking necessary vaccinations.

Fruit flies show how salmonella escapes immune defenses

Researchers used a transgenic fruit fly model to study how Salmonella evades immune defenses, finding that the protein AvrA shuts down key signaling pathways. This allows the bacteria to cause severe intestinal infections. The study's results suggest that other pathogens may target similar biochemical networks to avoid elimination.

Blood pressure enzyme can have tumor-sensing role

Researchers found that increasing production of angiotensin-converting enzyme in macrophages enhances the immune system's ability to sense and respond to tumors. This discovery suggests a strategy for amplifying immune system function in humans, potentially enhancing cancer patients' ability to resist tumor growth.

Alcohol may amplify chronic rejection in lung transplants

A recent study found that chronic alcohol consumption by lung donors promotes scarring and airway injury after transplantation. The research, published in the American Journal of Respiratory and Critical Care Medicine, raises questions about human lung donors with a history of alcohol abuse.
