Researchers aim to overcome resistance to bowel cancer screening in Scots

Academics are to look at ways to encourage Scots to take part in a new national screening programme for bowel cancer, a leading cause of cancer deaths in Western nations.

Better understanding of T cell response

Swedish and U.K. researchers report that an apparently "acute" human viral infection can cause a persistent, activated CD8+ T cell response a long time after patients have recovered.

Cheeks may hold the clue to lung cancer risk

According to Canadian researchers DNA changes in cells taken from the inside of the cheek are associated with a risk for stage I lung cancer.

Botox not just for glamour, great for stroke victims too

Botox, or botulinum toxin's, main claim to fame currently seems to be associated with stars and others who wish for fuller lips and ironed out wrinkles, but the treatment does in fact have a far more credible and worthwhile reputation which continues to grow.

Gene fusion appears to cause prostate cancer

Scientists at the University of Michigan Medical School, in collaboration with researchers at Harvard's Brigham and Women's Hospital, have discovered a recurring pattern of scrambled chromosomes and abnormal gene activity that occurs only in prostate cancer.

Hormone found naturally in the body has the ability to cause limited weight loss

Research at the Oregon National Primate Research Center (ONPRC) at Oregon Health & Science University has demonstrated that a hormone found naturally in the body has the ability to cause limited weight loss. Specifically, the research revealed that peptide YY (PYY) can reduce food consumption in the morning, leading to a mild level of weight loss in the short term.

Environment is a major factor influencing the success of the addiction recovery

New research in monkeys suggests that, although living in an "enriched" environment can make someone less vulnerable to abusing cocaine, once started, extended drug abuse can eliminate the social advantage the abuser originally had.

DCDC2 gene linked to dyslexia

Pediatric researchers at Yale School of Medicine have identified a gene on human chromosome 6 called DCDC2, which is linked to dyslexia, a reading disability affecting millions of children and adults.

Novel mouse model of medulloblastoma

A collaboration of researchers, led by Dr. Martine Roussel of St. Jude Children's Research Hospital, has developed a novel mouse model of medulloblastoma -- the most prevalent malignant pediatric brain tumor -- that the researchers hope will more accurately represent the genetic changes involved in human brain tumor development.

HDLs provide human immunity to certain parasites

For years biomedical researchers have known that high density lipoproteins, commonly called HDLs or "good cholesterol," are responsible for protecting humans from certain parasites, but couldn't explain how.

Morphine withdrawal enhances hepatitis C virus (HCV) replicon expression

Researchers at the University of Pennsylvania have demonstrated that morphine withdrawal complicates hepatitis C by suppressing IFN-alpha-mediated immunity and enhancing virus replication.

Discovery of how communication between cancer cells is controlled

The discovery, by scientists at Monash University and the Sloan Kettering Cancer Centre in New York, of how communication between cancer cells is controlled has promised new treatment options for malignant tumours.

Search for genes responsible for anxiety disorders

Increasing the activity of two enzymes better known for their role in oxidative stress metabolism turns normally relaxed mice into "Nervous Nellies," according to research conducted at the Salk Institute for Biological Studies and reported in the early online edition of Nature.

Researchers can now more accurately predict who will develop type 1 diabetes

In the process, they've also uncovered signs of a new protein that may forecast a more rapidly developing form of the disease. Together, these findings could help researchers screen patients for clinical trials that eventually may lead to a vaccine or cure for type 1 diabetes.

Scientists unravel complex mechanisms in the brain that regulate body weight

Scientists are one step closer to unraveling the complex mechanisms in the brain that regulate body weight. Working with mice -- whose appetites are controlled by systems very similar to those in humans – they have identified a specific type of neuron that is essential for feeding behavior.

Lack of sex could be a signpost to extinction

Researchers from Imperial College London believe that when species become asexual they could be on their way to extinction.

Scientists say there is less white matter in the frontal lobes of those who struggle with focusing

When it comes to focusing on a task amid distractions, some folks more than 60 years old are as mentally sharp as 22-year-olds. Others struggle. Researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign have shed some light on why that is.
