A discovery made 25 years ago about how the brain controls blood pressure regulation is only now being explored with the help of scientists from the Howard Florey Institute.
German scientist, Prof Wilfrid Jänig, is in Melbourne this month to collaborate with Florey scientists, Dr Robin McAllen and Dr Bradford Bratton, on his research involving a pathway in the brain that controls blood pressure and may worsen cardiovascular disease.

Scientists are now one step closer to improved treatment of Type 2 diabetes following significant findings made by scientists at Australia's Garvan Institute of Medical Research. World-wide, more than 200 million people suffer from this disease, resulting in disability and reduced life expectancy. In Australia it affects around 7% of the population.
People with Type 2 diabetes do not produce enough insulin, a hormone made in the pancreas that helps convert the sugar in our blood into energy in our muscles. Current therapies force our bodies to make more insulin, make better use of the insulin that already exists or mimic the action of insulin. But none of these therapies specifically address the reasons why insulin production fails in the first place.

New research by The George Institute for International Health in Sydney, Australia has found that lowering blood pressure protects stroke victims with Chronic Kidney Disease from further strokes or heart attacks. Given the high risk of cardiovascular complications in people with Chronic Kidney Disease (CKD), these results have significant implications for millions of people across the world.
According to lead author, Dr Vlado Perkovic at The George Institute, most of the CKD population will die from cardiovascular complications. "People with Chronic Kidney Disease are at a significantly greater risk of cardiovascular events than those without the disease. We found that approximately twice as many cardiovascular events were prevented when a perindopril based blood pressure lowering regimen was used in these people, compared to people with normal kidney function."

Ryle Dwyer writes on the horror of the 1918-20 pandemic which the propaganda says was caused by Spanish flu (Irish Examiner, May 1 [2003]).
How did they know it was the virus of Spanish flu that killed millions of civilians and soldiers? This disaster occurred when viruses were unknown to medical science. It took a British science team to identify the first virus in man in 1933.

Microscopic worms used for scientific research are living longer despite cellular defects, a discovery that is shedding light on how the human body ages and how doctors could one day limit or reverse genetic mutations that cause inherited diseases, according to a new University of Colorado at Boulder study.
In the first formal study of its kind, researchers manipulated the metabolic state of genetically engineered lab worms called C. elegans and discovered a window of high-efficiency cellular processing that enabled the worms to slow their rate of aging. The findings could one day contribute to the creation of gene therapies to reverse or lessen the effects of mitochondrial diseases, the largest family of human genetic diseases, said lead study author Shane Rea of CU-Boulder's Institute for Behavioral Genetics in Boulder, Colorado.

Afghanistan has begun its latest drive to vaccinate millions of children under five against the crippling polio virus, United Nations Assistance Mission in Afghanistan (UNAMA) officials have said.
The three-day campaign is the fifth in Afghanistan this year and was launched Sunday by the Afghan Ministry of Public Health (MoPH), with the support of the United Nations Children's Fund (UNICEF), the World Health Organization (WHO), Rotary International and other partners.

There is a biological reason why events that occur in tandem with emotions such as fear, anger and joy are far more memorable, a U.S. study found.
Researchers at The John Hopkins University in Baltimore, Cold Spring Harbor Laboratory in New York and New York University have identified a hormone that is released during emotional arousal; they believe the hormone "primes" nerve cells to remember events.

Some scientists think they have figured out the real job of the troublesome and seemingly useless appendix: It produces and protects good germs for your gut. That's the theory from surgeons and immunologists at Duke University Medical School, published online in a scientific journal this week.
For generations the appendix has been dismissed as superfluous. Doctors figured it had no function, surgeons removed them routinely, and people live fine without them.

Research in Germany linked higher infection risks, especially for diarrhea, to babies who swam in pools during their first year of life.
However, the study, published in the International Journal of Hygiene and Environmental Health, found no increased risks for atopic diseases -- which is when the immune system is dysregulated, resulting in allergic inflammation.

British researchers are investigating whether an extract from bilberries -- already known to help with night vision -- can prevent or delay some cancers.
Andy Gescher and colleagues at the University of Leicester, is leading an investigation to carry out clinical trials with the commercially produced substance Mirtoselect -- extracted from bilberries -- with the cooperation of patients about to undergo surgery for colorectal and liver cancer.
