Important steps towards the development of a human vaccine against malaria

Every day 2,000 children die from malaria in Africa alone. The infection is transmitted from human to human by biting mosquitoes and remains one of the world's most devastating diseases. Despite many years of effort a vaccine is still not available but is urgently needed, if we are to make an impact on this enormous problem.

Vigorous exercise protects against breast cancer

Normal-weight women who carry out lots of vigorous exercise are approximately 30% less likely to develop breast cancer than those who don't exercise vigorously.

Good genes behaving badly behind type 1 diabetes

Investigators combing the genome in the hope of finding genetic variants responsible for triggering early-onset diabetes may be looking in the wrong place, new research at the Stanford University School of Medicine suggests.

Cancer requires support from immune system to develop, researchers report

Tumors that grow around nerves in a rare genetic disease need cooperation from cells from the immune system in order to grow, reports a team of scientists, including researchers from UT Southwestern Medical Center.

Drinking milk to ease milk allergy?

Giving children with milk allergies increasingly higher doses of milk over time may ease, and even help them completely overcome, their allergic reactions, according to the results of a study led by the Johns Hopkins Children's Center and conducted jointly with Duke University.

Blood stored for 29 days or more linked to infection

Blood stored for 29 days or more, nearly 2 weeks less than the current standard for blood storage, is associated with a higher infection rate in patients who received transfusions with the blood.

Gene against bacterial attack unravelled

Dutch researcher Joost Wiersinga from AMC Medical Centre in Amsterdam has unravelled a genetic defence mechanism against the lethal bacteria Burkholderia pseudomallei. The research is the next step towards a vaccine against this bacterium suitable for bioweapons.

New tuberculosis vaccine safer, more effective than BCG vaccine for HIV-positive people

A new tuberculosis vaccine could be safer and more effective than the currently available BCG vaccine, particularly for HIV-positive people, according to a study to be published in the November issue of Infection and Immunity, IANS/Times of India reports (IANS/Times of India, 10/24).

Cholesterol-lowering statins associated with lower risk of death from pneumonia

Individuals who take cholesterol-lowering statins before being hospitalized with pneumonia appear less likely to die within 90 days afterward, according to a report in the October 27 issue of Archives of Internal Medicine.

In mice, anxiety is linked to immune system

In the first study ever to genetically link the immune system to normal behavior, scientists at Rockefeller and Columbia universities show that mast cells, known as the pharmacologic bombshells of the immune system, directly influence how mice respond to stressful situations.

The sooner the better when it comes to HIV/AIDS treatment

New research into HIV/AIDS therapy has found that starting treatment with drugs for the AIDS virus may be better sooner than later as victims are more than 70% less likely to die when they started taking cocktails of HIV drugs earlier than currently recommended.

Warnings in NSW of whooping cough outbreak

An outbreak of whooping cough in New South Wales is causing some concern - the NSW Health Department says infection rates have soared from 2,000 cases last year, to 3,800 cases this year, and the increase is more so in some areas.

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.

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.

New molecules with many branches will help unleash potential of nanotechnology

Materials science and the pharmaceutical industry could soon be revolutionized by emerging nanotechnologies based on designer molecules with long complex tree-and branch structures. Such molecules offer almost limitless scope for design of bespoke compounds for specific applications in disease therapy, for novel materials such as resins, as well as electronic displays, and energy storage. Almost every field involving design and synthesis of chemical compounds will be transformed by the arrival of technologies allowing nanoscale design of these branched molecules, known as hyperbranched polymers.

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.
