Drug tracked in tissue
17 October 2011 When a new drug is developed, the manufacturer must be able to show that it reaches its intended goal in the body’s tissue, and only that goal. Such studies could be made easier with a new method now established at Lund University in Sweden. The method is a special type of mass spectrometry which can be used on drugs 'off the shelf', i.e. without any radioactive labelling which may change the behaviour of the drug.

Enzyme identified as possible reason for multiple miscarriage and infertility
Professor Jan Brosens from Warwick Medical School has unveiled research which shows how abnormal regulation of an enzyme in the inner wall of the uterus may be at the root of infertility and miscarriage. The findings have implications for the treatment of infertility and recurrent miscarriage and could also lead to new contraceptives.

Effects of ’cognitive enhancement’ drug on sleep-deprived doctors
Researchers have carried out a preliminary study looking at the effects of the 'cognitive enhancement' drug modafinil on the performance of doctors who had been deprived of sleep for one night. Modafinil, discovered in the 1970s, is currently prescribed in the UK for the treatment of sleepiness associated with narcolepsy, sleep apnoea, and shift work sleep disorder, a condition that affects people who frequently have to work at night.

Diagnosis guidelines may be inadequate to help clinicians detect viable pregnancies thought to be miscarriages
Adapted from a news release issued by Wiley-Blackwell Friday 14 October Current guidelines that help clinicians decide whether a woman has had a miscarriage are unreliable, possibly resulting in the inadvertent termination of wanted pregnancies, according to new research. The findings from three new studies at Imperial College London and Katholieke Universiteit Leuven show that a viable embryo may be present in some cases in which a miscarriage has been diagnosed.

Kill the stem cells responsible for brain tumors
Researchers have developed a new screening approach to identify chemical compounds that can target and kill the stem cells responsible for creating deadly brain tumors. Glioblastoma is one of the deadliest malignancies, typically killing patients within 12 to 18 months. These brain cancers consist of two kinds of cells: a larger, heterogeneous population of tumor cells and a smaller sub-population of stem cells, which are treatment-resistant.

Stem cells could help repair damaged heart muscle
New research has found that stem cells derived from human cord blood could be an effective alternative in repairing heart attacks. At least 20 million people survive heart attacks and strokes every year, according to World Health Organisation estimates, but many have poor life expectancy and require continual costly clinical care.

Economic Conditions and Alcohol Consumption
Previous studies have found that health outcomes improve during an economic downturn. Job loss means less money available for potentially unhealthy behaviors such as excessive drinking, according to existing literature on employment and alcohol consumption. A new study by health economist Michael T. French from the University of Miami and his collaborators has concluded just the opposite-heavy drinking and alcohol abuse/dependence significantly increase as macroeconomic conditions deteriorate.

Vitamin D is crucial against tuberculosis
Vitamin D is crucial against tuberculosis
Vitamin D is not just important for building strong bones - it also plays an essential role in the body's fight against infections such as tuberculosis, an international research team has found. Tuberculosis, a potentially fatal lung disease, causes an estimated 1.8 million deaths annually, according to the World Health Organization, and it especially impacts those with reduced immunity, such as HIV-infected individuals.

15-year increase in life expectancy for people with HIV in UK
15-year increase in life expectancy for people with HIV in UK
New research has found the life expectancy of HIV-positive individuals in the UK has increased by over 15 years since 1996. The findings, published today [12 Oct 2011] in the BMJ , suggest that improvements in antiretroviral therapy treatment has helped people with the disease to live longer. Until now, few studies have estimated how long those with HIV in the UK are likely to live.

Acidic food and drink can damage teeth
Eating fruit such as apples could be up to four times more damaging to teeth than carbonated drinks, according to a new study led by Professor David Bartlett at the King's Dental Institute. Published in the Journal of Dentistry , the study looked at links between diet and tooth wear at several sites in the mouth, in more than 1,000 men and women aged 18 to 30.

Dialysis for kidney disease now initiated earlier
It has become increasingly clear that patients in the United States are starting dialysis at higher and higher levels of kidney function. A team of researchers, led by Ann O'Hare , University of Washington associate professor of medicine and affiliate investigator at Group Health Research Institute , set out recently to find out what this means for patients, and how much earlier patients are starting dialysis compared with past practices.

Everest expedition suggests nitric oxide benefits for patients in intensive care
The latest results from an expedition to Mount Everest that looked at the body's response to low oxygen levels suggest that drugs or procedures that promote the body's production of a chemical compound called nitric oxide (NO) could improve the recovery of critically ill patients in intensive care. Oxygen is required by all larger organisms, including humans, to survive.

Three gene faults linked to melanoma
An international team of researchers has discovered the first DNA faults linked to melanoma - the deadliest skin cancer - that are not related to hair, skin or eye colour. Cancer Research UK scientists at the University of Leeds, together with a team from the GenoMEL consortium, scanned the genes in blood samples from almost 3000 Europeans with melanoma, and compared these with samples taken from the general population.

The secret life of the American teen
Andrew Fuligni and his colleagues want to understand the secret life of the American teenager. Their research has examined whether stress in the teen years affects kids' health as adults (it does), whether teens maintain their religious ties and beliefs as adults (they do) and if ethnic minority-based stigmatization affects how they perform in school (it does).

New method to diagnose sinusitis could reduce use of antibiotics
05 October 2011 A new method of diagnosing sinusitis is presented in a new thesis from Lund University. The results offer the potential to reduce the use of antibiotics and the costs of the disease to society. Sinusitis is a very common disease and exists in both an acute and a chronic form. In Europe, over nine per cent of the population suffers from chronic sinusitis.
