Ketamine reduces suicidality in depressed patients
Drug treatment options for depression can take weeks for the beneficial effects to emerge, which is clearly inadequate for those at immediate risk of suicide. view more (2009-09-10)
Study identifies a common genetic risk factor for colorectal and prostate cancer
A study led by researchers at the Keck School of Medicine of the University of Southern California (USC) has found that one of seven genetic risk factors previously identified as increasing the probability of developing prostate cancer also increases the probability of developing colorectal cancer. view more (2007-07-09)
Biological FM signal maintains inflammation in cancer, asthma and other diseases
A study published in Science examines a key player in conditions such as cancer, inflammatory bowel disease, rheumatoid arthritis and asthma and has shown that cells use a sophisticated communication system to coordinate responses to infection and maintain inflammation in the body. view more (2009-04-10)
Purdue-IU researchers explore new method for early disease diagnosis
Purdue University researchers worked with the Indiana University School of Medicine to establish a technique that provides a new approach for detecting a number of genetic disorders found in infants and young children. view more (2007-07-19)
Osteoarthritis may be sign of faster 'biological ageing'
Osteoarthritis, the degenerative inflammatory bone disease, may be a sign of faster "biological ageing," suggests research published ahead of print in the Annals of the Rheumatic Diseases. view more (2006-10-02)
Blood test identifies women at risk from Alzheimer's
Middle-aged women with high levels of a specific amino acid in their blood are twice as likely to suffer from Alzheimer's many years later, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden. view more (2009-11-09)
Plastic-Protein Hybrids
Functional membrane proteins in a block copolymer matrix Biological membranes form a fluid matrix, in which proteins "swim". Many of these membrane proteins are of interest for both pharmacological and biotechnological applications - for example, they are under consideration as biosensors for the rapid screening of pharmaceutical agents.... view more...

UK scientists all set for New Year encounter with a comet
On January 2nd 2004 the NASA space mission, STARDUST, will fly through comet Wild 2, capturing interstellar particles and dust and returning them to Earth in 2006. Space scientists from the Open University and University of Kent have developed one of the instruments which will help tell us more about comets and the evolution of our own solar... view more...

BRAIN RESEARCH REVEALS STRUCTURAL DIFFERENCES IN VIOLENT OFFENDERS WITH MENTAL DISORDERS
New brain imaging data has revealed structural differences in the brains of violent offenders with mental disorders, bringing research closer to finding a biological basis for violent behaviour in the mentally ill. Preliminary findings were reported by researchers from London's Institute of Psychiatry at the International Congress on Schizophrenia... view more... (1999-04-19)
MRI: A window to genetic properties of brain tumors
Doctors diagnose and prescribe treatment for brain tumors by studying, under a microscope, tumor tissue and cell samples obtained through invasive biopsy or surgery. view more (2008-03-25)
Apollo 11 moon rocks still crucial 40 years later, say WUSTL researchers
A lunar geochemist at Washington University in St. Louis says that there are still many answers to be gleaned from the moon rocks collected by the Apollo 11 astronauts on their historic moonwalk 40 years ago July 20. view more (2009-07-20)
Increased levels of Muellerian-inhibiting substance could mean greater breast cancer risk
Women with increased levels of Müllerian inhibiting substance (MIS), best known for regulating in utero sexual differentiation in boys, may be at a greater risk for breast cancer. view more (2009-10-12)
Breakthrough in pre-eclampsia test
A team at the University of Leeds has discovered a way of diagnosing pre-eclampsia, a condition which affects almost one in ten pregnant women and accounts for up to 15% of all premature deliveries. view more (2008-02-13)
New study shows way to avoid overtreatment in breast cancer
The numbers of women who receive adjuvant chemotherapy for breast cancer could be reduced by 30 to 40% if the results of a new molecular study are put into practice. Dr Laura van 't Veer from the Netherlands Cancer Institute told the news briefing that micro array technology* can help predict which breast cancers will metastasise (spread) and... view more...

Our genome changes over lifetime, Johns Hopkins experts say
Researchers at Johns Hopkins have found that epigenetic marks on DNA-chemical marks other than the DNA sequence-do indeed change over a person's lifetime, and that the degree of change is similar among family members. view more (2008-06-25)
St. Jude finds young age may give survival advantage to children with certain brain tumors
St. Jude Children's Research Hospital investigators have shown that children under 3 years old who have a brain tumor called diffuse pontine glioma (DPG) appear to have a better outcome than older children with the same cancer. view more (2008-05-30)
In a rare disorder, a familiar protein disrupts gene function
As reported this week in the open-access journal PLoS Biology, an international team of scientists studying a rare genetic disease has discovered that a bundle of proteins already known to be important for keeping chromosomes together also plays an important role in regulating gene expression in humans. view more (2009-05-27)
New NIST reference material for peptide analysis
The National Institute of Standards and Technology (NIST) has issued its first-ever reference material designed to improve the performance and reliability of experiments to measure the masses and concentrations of peptides in biomolecular samples. view more (2007-05-29)
The mental health dangers of birth hypoxia
Complications during pregnancy and birth, such as birth hypoxia - the shortage of oxygen in the body - are associated with an increased risk for schizophrenia. view more (2008-10-28)
Pesticides Persist in Ground Water
Numerous studies over the past four decades have established that pesticides, which are typically applied at the land surface, can move downward through the unsaturated zone to reach the water table at detectable concentrations. view more (2008-07-02)
