Scientists make breakthrough in study of Autoimmune Disease
Diseases of the immune system such as multiple sclerosis, rheumatoid arthritis and psoriasis could be treated by a gas produced naturally by the body, scientists at the University have found. Autoimmune disease occurs when a person's immune system attacks his own body. It is a major global health problem and it is vital that better treatment is found.

Retina holds the key to better vision in deaf people
Retina holds the key to better vision in deaf people People who are deaf benefit from better vision due to the fact their retinas develop differently, experts at the University of Sheffield have shown. The research, which was funded by RNID – Action on Hearing Loss and published today (1 June 2010) in the journal PlosONE suggests that the retina of adults who are either born deaf or have an onset of deafness within the very first years of life actually develops differently to hearing adults in order for it to be able to capture more peripheral visual information.

Brain study shows why alcoholics fall off the wagon again and again
A new University of Sussex study adds to our understanding of why recovering alcoholic patients find it so hard to give up boozing for good. Researchers looked at the behaviour and brain activity of alcoholic patients who had recently undergone detoxification, and found that the very act of detoxification from alcohol results in damage to the areas of the brain that veto spontaneous desire - such as the desire to drink.

Study offers hope for cancer therapy
Ovarian cancer patients could be helped by a test that identifies the specific type of tumour they have. University researchers hope this improved diagnosis will help doctors to personalise treatment programmes so that patients receive the most effective drugs. The Edinburgh team worked with scientists from Ireland to identify six subgroups of the disease, each of which had a different genetic signature.

Pancreas betrayed by 'double agent'
Pancreas betrayed by 'double agent'
Science | Health Jonathan Wood | 27 May 11 Stellate cells, a type of cell in the pancreas which normally helps the body respond to damage or disease of the pancreas, can act as a double agent when it comes to cancer. These mysterious cells become 'partners in crime' with pancreatic cancer cells, Oxford University researchers have shown, stimulating growth of the cancer cells and protecting them against radiotherapy.

African trial questions emergency treatment of children in shock
African trial questions emergency treatment of children in shock
Giving fluids rapidly through a drip into a vein (fluid resuscitation) as an emergency treatment for African children suffering with shock from severe infections does not save lives, according to a major clinical trial funded by the Medical Research Council (MRC). The ground-breaking research showed that giving children fluids slowly to replace the needs of a sick child who cannot drink, rather than rapid fluid resuscitation, is safer and more effective in aiding recovery.

High risk of Parkinson’s disease for people exposed to pesticides near workplace
In April 2009, researchers at UCLA announced they had discovered a link between Parkinson's disease and two chemicals commonly sprayed on crops to fight pests. That epidemiological study didn't examine farmers who constantly work with pesticides but people who simply lived near where farm fields were sprayed with the fungicide maneb and the herbicide paraquat.

Polypill halves predicted heart disease and stroke risk in international trial
Polypill halves predicted heart disease and stroke risk in international trial
The world's first international polypill trial has shown that a four-in-one combination pill can halve the predicted risk of heart disease and stroke. The results are published online today in the open access journal PLoS ONE . The once-a-day polypill contains aspirin and agents to lower blood pressure and cholesterol.

Study links wealth to diabetes death risk
Having diabetes has the same effect on someone's risk of death as living in a very deprived community, research shows. University researchers have found that people with Type 2 diabetes from an affluent background had the same risk of dying as someone without the condition from a deprived area. But the highest risks of suffering an early death remained in patients from the worst off backgrounds who had diabetes.

Cockroach Allergens and Childhood Asthma
Cockroach Allergens in the Home May Help Explain Why Childhood Asthma is More Prevalent in Some Urban Neighborhoods Than Others Children living on NYC blocks where asthma is common have higher levels of exposure to cockroach allergens and are more likely to be sensitized to it. In New York City, the prevalence of asthma among children entering school varies by neighborhood anywhere from 3% to 19%, and children growing up within walking distance of each other can have 2-3 fold differences in risk for having asthma.

Research study reveals profile for female drink-drivers
PA 169/11 Female drink-drivers are more likely to be older, better-educated and divorced, widowed or separated, research has shown. The study by academics at The University of Nottingham found that emotional factors and mental health problems were common triggers in alcohol-related offences committed by women.

Treating HIV patients early with antiretrovirals significantly reduces spread of virus to partners
Administering antiretroviral medicines to HIV-positive men and women when their immune systems are relatively healthy reduces their risk of transmitting the virus to sexual partners by 96 percent, according to findings from a large-scale clinical study sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Nerve-stimulation treatment effective against epilepsy
Nerve-stimulation treatment effective against epilepsy
Medications are the mainstay of treatment for epilepsy, but for a considerable number of patients — estimated to be as many as 1 million in the U.S. — drugs don't work. These patients suffer from a type of epilepsy known as refractory or drug-resistant epilepsy, in which drugs can't control their seizures .

Expert discovers simple method of dealing with harmful radioactive iodine
Expert discovers simple method of dealing with harmful radioactive iodine A novel way to immobilise radioactive forms of iodine using a microwave, has been discovered by an expert at the University of Sheffield. Iodine radioisotopes are produced by fission of uranium fuel in a nuclear reactor. Radioactive iodine is of concern because it is highly mobile in the environment and selective uptake by the thyroid gland can pose a significant cancer risk following long term exposure.

Quality of nursing home care no protection against litigation
Providing high quality care in nursing homes does little to guard against risks of being sued, a new University of Melbourne study has found. The Melbourne Law School study found the risks of being sued differed only slightly between the highest and lowest quality nursing homes. Published in the New England Journal of Medicine, Relationship between Quality of Care and Negligence Litigation in Nursing Homes analysed negligence claims brought against 1465 nursing homes in the US between 1998 and 2006.

Caltech researchers develop quick, low-cost, and portable microchip for immune monitoring and clinical applications PASADENA, Calif.—There's a wealth of health information hiding in the human immune system. Accessing it, however, can be very challenging, as the many and complex roles that the immune system plays can mask the critical information that is relevant to addressing specific health issues.

Scientists find new drug target in breast cancer
Scientists find new drug target in breast cancer
Researchers have identified a new protein involved in the development of drug resistance in breast cancer which could be a target for new treatments, they report today Medicine. In a mouse model of breast cancer, blocking production of the protein using genetic techniques caused tumours to shrink. The scientists are now looking for new drugs which could achieve a similar effect.

Does Eating Give You Pleasure, or Make You Anxious?
New study reveals biological reasons for feelings of anxiety instead of reward in patients with anorexia May 19, 2011 By Debra Kain Perhaps the most puzzling symptom of anorexia nervosa - a disorder that tends to occur in young women - is the refusal to eat, resulting in extreme weight loss. While most people have a great deal of difficulty in dieting and losing weight, particularly if a diet extends over many months or years, individuals with anorexia nervosa can literally diet themselves to death.
