APOE ε4 predicts risk of future depression

One of the most powerful predictors in neuropsychiatry is the epsilon 4 (ε4) allele of the apolipoprotein gene (APOE).

HIV, Ebola appear to be of animal origin

The hepatitis A virus can trigger acute liver inflammation which generally has a mild course in small children but which can become dangerous in adults.

Researchers develop biochemical trick that can extend lifespan of peptides

Researchers at University of the Pacific have developed a biochemical trick that can significantly extend the lifespan of peptides, smaller cousins of proteins. The finding opens up new possibilities for creating peptides to treat cancer, infertility and other conditions.

Preschoolers' working memory can predict later dropout risk

Preschoolers who score lower on a working memory task are likely to score higher on a dropout risk scale at the age of 13, researchers at Université Sainte-Anne and the University of Montreal revealed today.

Scientists identify protein that helps map brain tumours

Scientists have discovered a protein that helps map the edge of brain tumours more clearly so they show up on magnetic resonance imaging (MRI) scans, according to new research presented at the National Cancer Research Institute Cancer Conference in Liverpool today.

Loughborough researchers secure £545,000 to help tackle Antimicrobial Resistance

Researchers at Loughborough University have secured £545,000 to help tackle growing resistance to antibiotics.

Hypersexual disorder can be linked to hyperactive stress systems

New research from Karolinska Institutet in Sweden shows that hypersexual disorder - known popularly as sex addiction - can be linked to hyperactive stress systems. In a stress regulation test using the cortisone drug dexamethasone, men with hypersexual disorder showed higher levels of stress hormones than controls, a finding that the researchers hope will contribute to improved therapy for this patient group.

Duke University mathematicians developing ways to help doctors predict tumor growth

Mathematicians at Duke University are developing ways to help doctors predict how different cancers are likely to progress when actual measurements of tumor growth are hard to come by.

New combination treatment provides better wound healing compared to SSGs alone

The use of meshed split skin autographs (SSGs) is a standard treatment for large, deep burns. However, serious scarring is often a result. In an effort to improve wound healing and reduce scarring, a team of researchers in The Netherlands tested a treatment technique on patients with serious, deep burns that employed SSGs along with autologous cultured proliferating epidermal cells (ECs) compared to SSGs alone.

New peptide-based hydrogel could one day facilitate microsurgery

Skillful surgeons can do amazing things in extremely small places, but finding better ways to suture tiny blood vessels has been an ongoing challenge for even the best.

TSRI scientists awarded NIH grant to investigate molecular machinery involved in cancer metastasis

Cancer metastasis occurs when tumor cells escape from a primary tumor, via the blood stream, and establish tumors in secondary locations. When the metastases are found in distant tissues and organs, doctors call this stage IV cancer, and the survival rate is low.

PolyU researchers develop novel biosensor for measuring glucose level in saliva

Diabetic patients have to monitor blood glucose regularly and frequently, but conventional method of taking blood sample for measuring glucose level is painful. It is therefore important to develop high performance biological sensors for monitoring the glucose level at a reasonable cost.

Secret tunnels used by cancer cells can be exploited to deliver drug therapies, suggests new study

A new discovery published in the Nov. 2015 issue of The FASEB Journal shows that cancer cells use previously unknown channels to communicate with one another and with adjacent non-cancerous cells.

Findings suggest potential metabolic pathway against cancer

When cancer cells compete with immune cells for glucose, the cancer wins. As a result, the immune T cells are not healthy and don't have the weapons to kill the cancer.

Rice scientists solve long-standing mystery about hemophilia protein

Rice University scientists have solved a long-standing mystery about where the body stores and deploys blood-clotting factor VIII, a protein that about 80 percent of hemophiliacs cannot produce due to genetic defects.

Inhibiting key enzyme pathways decreases inflammation and frailty in aged mice

Chronic inflammation, closely associated with frailty and age-related diseases, is a hallmark of aging. Mayo Clinic researchers have discovered that inhibiting key enzyme pathways reduces inflammation in human cells in culture dishes and decreases inflammation and frailty in aged mice.

Salk scientists uncover enzyme responsible for suppressing deadly lung cancer

Scientists at the Salk Institute have uncovered a molecule whose mutation leads to the aggressive growth of a common and deadly type of lung cancer in humans.

Research sheds new light on the fight against tonsil cancer

Researchers at Simon Fraser University and the BC Cancer Agency have developed a groundbreaking method to identify and separate stem cells that reside in the tonsils. Their research, which sheds new light on the fight against oral cancer, is published today in the journal Stem Cell Reports.

Findings support higher dietary requirements of vitamin E for obese people with metabolic syndrome

A recent study suggests that obese people with metabolic syndrome face an unexpected quandary when it comes to vitamin E - they need more than normal levels of the vitamin because their weight and other problems are causing increased oxidative stress, but those same problems actually cause their effective use of vitamin E to be reduced.

Researchers use genomic techniques to show why different strains of Salmonella infect particular animal species

It's called bird flu for a reason. Particular characteristics about the influenza virus known as H5N1 allow it to primarily affect avifauna, though in some worrying cases the disease has been passed to humans.
