Scientists Uncover a Novel Gene for Infantile Parkinson Disease
Scientists at the University of Birmingham have discovered genetic mutations that cause a rare childhood neurological disorder that could also have important implications for our understanding of Parkinson's disease. Led by Professor Eamonn Maher and Manju Kurian, the Birmingham team conducted detailed genetic sequencing in two families who had children diagnosed with infantile parkinsonism-dystonia (IPD) - a rare, recently discovered, genetic condition that produces symptoms similar to Parkinson's disease in children.

Cell biologist Richard Strohman has died at 82
BERKELEY — Richard Campbell Strohman, professor emeritus of molecular and cell biology at the University of California, Berkeley, and a frequent critic of the idea that genes determine destiny, died July 4 from complications of Alzheimer's disease. Born May 5, 1927, in Brooklyn, N.Y., Strohman trained in biology at the Biophysical Labs at Columbia University, from which he obtained a B.S. (1952) and Ph.D.

Salmonella Breakthrough Offers Hope for Vaccine
Scientists at the University of Birmingham have identified a protein present in non-typhoidal Salmonella (NTS) that could form the basis of a vaccine to protect against the infection that kills many tens of thousands in the developing world. In research published in PNAS, researchers reveal that a protein found on the surface of NTS called OmpD, may protect against these infections when purified from the bacteria and used in a vaccine.

Surprising new insights into the repair strategies of DNA
Surprising new insights into the repair strategies of DNA
PA 193/09 A microscopic single-celled organism, adapted to survive in some of the harshest environments on earth, could help scientists gain a better understanding of how cancer cells behave. Experts at The University of Nottingham were astonished to discover that the archaeon Haloferax volcanii was better at repairing DNA damage if enzymes, that are widely considered to be critically important in coordinating the repair of DNA, were mutated.

Researchers find early markers of Alzheimer's disease
Researchers find early markers of Alzheimer's disease
BERKELEY — A large study of patients with mild cognitive impairment revealed that results from cognitive tests and brain scans can work as an early warning system for the subsequent development of Alzheimer's disease. The research found that among 85 participants in the study with mild cognitive impairment, those with low scores on a memory recall test and low glucose metabolism in particular brain regions, as detected through positron emission tomography (PET), had a 15-fold greater risk of developing Alzheimer's disease within two years, compared with the others in the study.

Lower risk of dementia for married or cohabiting people
People who live alone have twice the risk of developing dementia and Alzheimer's disease in later life compared with married or cohabiting people, according to a research study led by Miia Kivipelto from Karolinska Institutet and published on the prominent British Medical Journal's website, According to Kivipelto, being widowed or divorced in mid-life carries three times the risk of developing dementia.

Many common genes behind schizophrenia
Genetic vulnerability to schizophrenia can be explained by the combined effect of a large number of common genes, according to a new study published in the prominent journal Nature. These genes are also linked to bipolar disorder. "As well as the connection between schizophrenia and the combined effect of a large number of genes, we have also obtained some indications that individual genes which form part of the immune system may provide protection against schizophrenia," says Christina Hultman, Professor of psychiatric epidemiology at Karolinska Institutet.

Lack of sleep could be more dangerous for women than men
Women who get less than the recommended eight hours? sleep a night are at higher risk of heart disease and heart-related problems than men with the same sleeping patterns, according to a UCL research published today in the journal SLEEP . The study, which was conducted with the Sleep Medicine Unit at the University of Warwick, showed that women who reported sleeping eight hours had significantly lower levels of a marker related to coronary heart disease (Interleukin-6) than those who reported sleeping seven hours per night.

Genetic changes after Caesarean section may explain increased risk of developing disease
Researchers at Karolinska Institutet have discovered that babies born by planned Caesarean section experience changes to the DNA pool in their white blood cells, which could be connected to altered stress levels during this method of delivery. The findings, presented in the July issue of the scientific journal Acta Paediatrica, may be a part of an explanation for why babies born by Caesarean section have an increased risk of developing certain disease in later life.

Breakthrough in combating the side effects of Quinine
Breakthrough in combating the side effects of Quinine
PA 181/09 Discovered back in the 1600s quinine was the first effective treatment in the fight against malaria - and it continues to be a commonly used treatment against this devastating disease. But the drug is associated with a long list of side effects which can range from sickness and headaches to blindness, deafness and in rare cases death — and until now no one knew why.

Lumbar punction is an important tool for the early diagnosis of Alzheimer's disease
The personal experience of patients' forgetfulness in everyday life combined with a sample of cerebrospinal fluid may be two important tools in the detection of Alzheimer's disease as early as possible. This is the conclusion of a study that has been published in Lancet Neurology, in which scientists from the Karolinska Institutet have followed patients with various forms of mild cognitive impairment for three years using, among other tests, analysis of cerebrospinal fluid.

Children susceptible to pesticides longer than expected, study finds
BERKELEY — Although it is known that infants are more susceptible than adults to the toxic effects of pesticides, this increased vulnerability may extend much longer into childhood than expected, according to a new study by researchers at the University of California, Berkeley. Among newborns, levels of paraoxonase 1 (PON1), an enzyme critical to the detoxification of organophosphate pesticides, average one-third or less than those of the babies' mothers.

Stress puts double whammy on reproductive system
Stress puts double whammy on reproductive system
BERKELEY — University of California, Berkeley, researchers have found what they think is a critical and, until now, missing piece of the puzzle about how stress causes sexual dysfunction and infertility. Scientists know that stress boosts levels of stress hormones - glucocorticoids such as cortisol - that inhibit the body's main sex hormone, gonadotropin releasing hormone (GnRH), and subsequently suppresses sperm count, ovulation and sexual activity.

Molecular Discovery Could Point the Way to New Treatment for Androgen Excess
Scientists at the University of Birmingham have uncovered a novel cause of androgen excess that may help to improve diagnosis and lead to the development of more effective treatment options for the condition polycystic ovary syndrome that affects between 5-15% of women. Researchers have discovered that a mutation in an enzyme responsible for deactivating the steroid dehydroepiandrosterone (DHEA) is sufficient to cause the over production of androgens in females.

New research reveals how specialist pre-pregnancy preparation for women and their partners is no different from the standard classes offered at antenatal clinics. In the study by the Department for Woman and Child Health at Karolinska Institutet, 1,087 first-time mothers and 1,064 of their partners took part.

Schizophrenia does not increase risk of violent crime
A new study from the Swedish medical university Karolinska Institutet and the University of Oxford finds that the severe mental disorder schizophrenia only marginally increases the risk of committing violent crime. Rather, the overrepresentation of individuals with schizophrenia in violent crime is almost entirely attributable to concurrent substance abuse.

Small risk of violence in schizophrenia unless drugs and alcohol are involved
There is an association between schizophrenia and violent crime, but it is minimal unless there are also drug or alcohol problems, a large-scale study led by Oxford University has shown. The findings, reported in the Journal of the American Medical Association, highlight the importance of treating drug or alcohol problems in people with severe mental illness.
