Respiratory syncytial virus may hide in the lungs, lead to asthma

Conventional wisdom has been that respiratory syncytial virus (RSV) - a common virus that causes infection in the lungs - comes and goes in children without any long lasting impact.

Feeling itchy? it may be stress!

German and Canadian researchers are suggesting that stress may make people itch - they say stress possibly activates immune cells in the skin and inflames it.

Human rhinovirus found to manipulate genes

Sneezing, runny nose and chills? You might blame the human rhinovirus (HRV), which causes 30 to 50 percent of common colds. But in reality, it's not the virus itself but HRV's ability to manipulate your genes that is the true cause of some of the most annoying cold symptoms.

Simple gene-based blood test, quicker, more accurate evaluation for cystic fibrosis

Researchers at National Jewish Health have identified a simple gene-based blood test that more accurately and quickly measures cystic fibrosis patients' response to therapy than current tests.

Even minimally symptomatic obstructive sleep apnea increases cardiovascular risk

People with even minimally symptomatic obstructive sleep apnea (OSA) may be at increased risk for cardiovascular disease because of impaired endothelial function and increased arterial stiffness, according to a study from the Oxford Centre for Respiratory Medicine in the UK.

High dose flu vaccine boosts immune response in elderly

Giving people age 65 and older a dose four times larger than the standard flu vaccine boosts the amount of antibodies in their blood to levels considered protective against the flu, more so than the standard flu vaccine does. The findings from a study of nearly 4,000 people were presented Oct. 26 at a national meeting on infectious diseases.

Life in Canada more deadly for immigrants?

Immigrants who come to Canada seeking a better life may in fact be setting themselves up for possible premature death.

Scientists discover how a well-known protein repairs broken DNA ends

During the life cycle of our cells, a minefield of environmental and biological assaults can lead to double-stranded DNA breaks, the most lethal and dangerous form of DNA damage. Now, in research published online this week in Nature, Rockefeller University scientists reveal that when these breaks occur, a protein called 53BP1 helps repair them by mobilizing their dangly DNA ends - findings that uncover a previously unknown aspect of how double-stranded breaks can get fixed.

A new role for a critical DNA repair molecule in the immune system

The human immune system is a brilliantly adaptable weapon against foreign invaders. But it all depends on the work of specialized cells called lymphocytes that have made a risky evolutionary gambit to mutate their own DNA.

Exposure to low doses of mercury changes the way the arteries work

An international team of researchers has shown that mercury is another important factor in cardiovascular disease as it changes the way arteries work. One of the possible sources of exposure of humans to mercury is by eating contaminated fish.

Why some people have a better head for languages

Learning a second language is usually difficult and often when we speak it we cannot disguise our origin or accent. However, there are important differences between individuals with regard to the degree to which a second language is mastered, even for people who have lived in a bilingual environment since childhood.

Grant funds research on environmental link to breast cancer

A foundation that funds research that examines the environmental causes of breast cancer has awarded a grant to a post-doctoral associate at the University of Rochester Medical Center.

Mouse genes guide search for human anxiety disorder genes

We are all familiar with the question - "Are you a man or a mouse?" What if the answer is "a little of both"? Because of the power of molecular genetics research in animals and the maturation of animal models, the path to identifying genes involved in particular types of behavior, such as fear, is much clearer in animals than in humans.

Memory function varies after damage to key area of the brain

Scientists at the University of Liverpool have discovered dramatic differences in the memory performance of patients with damage to the hippocampus, an area of the human brain key to memory.

Socioeconomic and treatment factors affect non-Hodgkin lymphoma patients' survival

Socioeconomic factors and the type of treatment received have an impact on a non-Hodgkin lymphoma (NHL) patient's risk of dying. That is the finding of a new study published in the December 1, 2008 issue of CANCER, a peer-reviewed journal of the American Cancer Society.
