Medicine & Health news

A new opportunity for hepatitis C research
The hepatitis C virus is highly specialised. We humans are its natural hosts. The only other living organisms that could be infected with the hepatitis C virus in the lab are chimpanzees. Nevertheless it is - from the viewpoint of the virus - highly successful: around 170 million people are chronically infected with the virus. And with the chronic infection the risk of developing liver cancer also increases.

Diagnostic blood test can identify rare lung disease

What are the symptoms of male menopause?
EU-funded scientists have identified the symptoms behind late-onset hypogonadism or 'male menopause', a rare condition that affects 2% of men. Nine symptoms were linked for the first time to low testosterone production, the key factor in male menopause. The seven-year study was part of the EMAS ('European male ageing study') project, which received over EUR 6 million under the 'Quality of Life and Management of Living Resources' Thematic programme of the EU's Fifth Framework Programme (FP5). The findings, which are published in the New England Journal of Medicine, are expected to better gauge the need for male testosterone therapy.

Experimental psychology used to investigate spatial perception in the presence of different color tones
A room will appear to be higher or lower depending on the lightness of the color tones used on ceiling and walls. However, it would seem there is no scientific basis for the old do-it-yourself rule to paint the ceiling in a hue slightly paler than the color used on the walls if you want to create the impression that a room is higher than it actually is. This is the conclusion reached following a study conducted by the Institute of Psychology of Johannes Gutenberg University Mainz (JGU) to investigate the effect of relative brightness of coloration of ceiling, walls and floor on the perceived height of interior spaces.

Neural stem cells attack glioblastoma cells
In their latest research, scientists of the Max Delbruck Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have demonstrated how the brain's own stem cells and precursor cells control the growth of glioblastomas. Of all brain tumors, glioblastomas are among the most common and most aggressive. Dr. Sridhar Reddy Chirasani, Professor Helmut Kettenmann and Dr. Rainer Glass have now shown in cell culture and mouse model experiments just how the body's own protective mechanism they identified in an earlier study, actually works.

New study contradicts negative perceptions of menopause
New research from the University of Sheffield has found that social and psychological factors have the biggest influence upon women's sexual behaviour during the menopause, rather than biological changes such as declining hormone levels.

Majority of Ontarians suffering from rheumatoid arthritis not receiving needed speciality care
Nearly 60 per cent of Ontarians with rheumatoid arthritis — an autoimmune disease that causes chronic inflammation of the joints — were not seen by a specialist within a one year period to treat the debilitating disease, according to a new study. Even more concerning is that women of child-bearing age are less likely to see a specialist than women 45 or older, say researchers from St. Michael's Hospital, the Institute for Clinical and Evaluative Sciences (ICES), and Women's College Hospital.

Head and spine trauma from ATV accidents cost $3.24 billion annually
Severe trauma to the head and spine resulting from all-terrain vehicle (ATV) accidents are increasing dramatically according to research released today from the University of Utah Department of Neurosurgery.

Sympathetic brain to blame for high blood pressure
High blood pressure can be attributed to a disruption of blood flow to the kidneys, known as renovascular hypertension, which is caused by a narrowing or obstruction of the blood vessels that supply the kidneys. To date, renovascular hypertension had been understood as the kidney's reaction to this disrupted blood flow, which triggers hormone release from the kidneys, causing retention of body fluids, thereby elevating blood pressure. 

Want to slow aging? New research suggests it takes more than antioxidants
Don't put down the red wine and vitamins just yet, but if you're taking antioxidants because you hope to live longer, consider this: a new study published in the June 2010 issue of the journal Genetics casts doubt on the theory that oxidative stress to our tissues shortens lifespan. That's because researchers from McGill University in Canada have identified mutations in 10 different genes of worms (genes believed to have counterparts in humans) that extend their lifespan without reducing the level of oxidative stress the worms suffer. The results contradict the popular theory that production of toxic reactive oxygen species in tissues is responsible for aging.

Researchers discover trigger to early, effective antibody response

Combining sex and drugs reduces rock and roll
Sharing a bottle of red wine may seem like the best recipe for a romantic interlude. However, the evening may not turn out as planned according to a Concordia University study, which evaluated the effect of a wide range of drugs, including alcohol, on sexual behaviour. The findings, published in the journal Hormones and Behavior, definitively show that despite our preconceived notions, use of many recreational drugs can cause a loss in that lovin' feeling.

Maternal diet and genes interact to affect heart development
A pregnant mother's diet may be able to interact with the genes her unborn child inherits and influence the type or severity of birth defect according to research funded by the Wellcome Trust and the British Heart Foundation (BHF). The study, published in the journal Human Molecular Genetics, suggests that mothers who eat a high fat diet before and through pregnancy could be inadvertently putting the health of their offspring at risk.
