Researchers collaborate to reduce effects of aging eye Posted: 17 Jan 2014 04:13 PM PST Aging gracefully may not be an option for the 40 million people worldwide who are blind or have significant visual impairment. It's reported that 65% of those with visual impairment and 82% of those who are blind are over 50 years of age. Ophthalmic leaders from around the world address "the aging eye" to focus attention on unmet needs and accelerate the translation of research findings into effective clinical care.

New study reveals links between alcoholic liver disease, circadian clock Posted: 17 Jan 2014 12:37 PM PST Researchers have revealed a putative role for the circadian clock in the liver in the development of alcohol-induced hepatic steatosis, or fatty liver disease.

Breakthrough technology enables gene silencing to heal wounds Posted: 17 Jan 2014 07:39 AM PST Researchers have developed a tissue scaffold that can deliver gene therapy to wounds over a period of several weeks.

New discovery on Giant Cell Arteritis sheds light on cause Posted: 17 Jan 2014 06:06 AM PST New research has revealed -- for the first time -- how the condition Giant Cell Arteritis (GCA) may be caused by a certain group of white blood cells called 'neutrophils'. GCA (also known as temporal arteritis) is a condition which causes severe inflammation in the blood vessels and primarily affects the elderly.

Patients with learning disabilities become 'invisible' in hospitals, says study Posted: 17 Jan 2014 06:05 AM PST Hospital patients with learning disabilities face longer waits and mismanaged treatment due to a failure to understand them by nursing staff, says a new report.

Statin use reduces delirium in critically ill patients Posted: 17 Jan 2014 05:58 AM PST Continued use of statins may help prevent delirium in critically ill patients who received statins before hospital admission, according to a new study of 470 intensive care patients in the UK.

45 years on: How serotonin makes schistosome parasites move Posted: 16 Jan 2014 04:03 PM PST Schistosoma mansoni and its close relatives are parasitic flatworms that affect millions worldwide and kill an estimated 250,000 people a year. A study identifies a new part of the molecular pathway that controls parasite movement. And because coordinated movement is essential for the schistosome life cycle in its human host, this protein is a promising new drug target.

Higher vitamin D levels associated with better cognition, mood in Parkinson's disease patients Posted: 16 Jan 2014 04:02 PM PST A new study exploring vitamin D levels in patients with Parkinson's disease (PD) opens up the possibility of a new avenue of early intervention that may delay or prevent the onset of cognitive impairment and depression.

Changes in brain gray matter volume associated with memory deficits in early Parkinson's disease Posted: 16 Jan 2014 04:02 PM PST Research by a team of investigators suggests that the free recall memory deficits common even in early stages Parkinson's disease are related to structural changes in the brain, specifically parietal cortical gray matter volume.

Risk factor identified for life-threatening disease in preemies Posted: 16 Jan 2014 01:20 PM PST Many premature infants suffer a life-threatening bowel infection called necrotizing enterocolitis (NEC). Researchers have now identified a marker to identify those infants who are at risk for the infection, enabling doctors to employ early preventive strategies.

Research sheds new light on heritability of disease Posted: 16 Jan 2014 10:08 AM PST A group of international researchers has published a paper describing a study aimed at better understanding how inherited genetic differences, or variants, predispose certain individuals to develop diseases such as type 2 diabetes. The study integrated computational methodology with experimentation to address and prove underlying genetic causes of type 2 diabetes.

Drugs that weaken traumatic memories hold promise for PTSD treatment Posted: 16 Jan 2014 10:06 AM PST Memories of traumatic events often last a lifetime because they are so difficult to treat through behavioral approaches. A preclinical study reveals that drugs known as histone deacetylase inhibitors can enhance the brain's ability to permanently replace old traumatic memories with new memories, opening promising avenues for the treatment of post-traumatic stress disorder and other anxiety disorders.

Team discovers key mechanisms to inhibit triple negative breast cancers Posted: 16 Jan 2014 10:05 AM PST A team of researchers have identified critical complex mechanisms involved in the metastasis of deadly "triple negative" breast cancers (TNBC). These tumors are extremely difficult to treat, frequently return after remission, and are the most aggressive form of breast cancer in women. The discovery of this critical interaction of mechanisms could be used to develop new life saving treatments to kill metastatic tumors in TNBC.

Important discovery for diagnosis of genetic diseases Posted: 16 Jan 2014 08:35 AM PST A new study shows the importance of the chromatin architecture in controlling the activity of genes, especially those required for proper embryonic development. This discovery could have a significant impact on the diagnosis of genetic diseases.
