A map for eye disease: Most detailed molecular map of eye region associated with vision loss Posted: 01 Aug 2014 09:50 AM PDT Vision specialists have created the most detailed molecular map of a region of the human eye associated with disease, including age-related macular degeneration. The map catalogs more than 4,000 proteins in each of three areas of the choroid.

'Normal' bacteria vital for keeping intestinal lining intact Posted: 01 Aug 2014 09:50 AM PDT Scientists have found that bacteria that aid in digestion help keep the intestinal lining intact. The findings could yield new therapies for inflammatory bowel disease and a wide range of other disorders.

Small RNAs in blood may reveal heart injury Posted: 01 Aug 2014 08:58 AM PDT Like clues to a crime, specific molecules in the body can hint at exposure to toxins, infectious agents or even trauma, and so help doctors determine whether and how to treat a patient. In recent years, tiny pieces of RNA called microRNAs have captured scientific attention for their potential as markers of health and disease.

New mothers still excessively sleepy after 4 months, study shows Posted: 01 Aug 2014 07:50 AM PDT New mothers are being urged to be cautious about returning to work too quickly, after a study found one in two were still excessively sleepy four months after giving birth. "Sleep disruption strongly influences daytime function, with sleepiness recognized as a risk-factor for people performing critical and dangerous tasks," an author of the new article said.

Recent use of some birth control pills may increase breast cancer risk, study suggests Posted: 01 Aug 2014 06:12 AM PDT Women who recently used birth control pills containing high-dose estrogen and a few other formulations had an increased risk for breast cancer, whereas women using some other formulations did not, according to new data.

Management of anticoagulant-associated intracerebral hemorrhage Posted: 01 Aug 2014 06:12 AM PDT A 20-page supplement has been published, covering the current knowledge of anticoagulant-associated intracerebral hemorrhage (AAICH) and methods in use for management of the condition. Intracerebral hemorrhage (ICH) is a potentially deadly form of hemorrhagic stroke. A medical emergency, ICH occurs when blood escapes into brain tissue from an injured or diseased blood vessel. Increased blood in the brain builds up pressure within the skull, which can cause unconsciousness and death.

Common herbal-based anti-malarial drug effective in controlling asthma, study suggests Posted: 01 Aug 2014 06:11 AM PDT Asthmatic patients may soon have a more effective way to control the condition, thanks to a new pharmacological discovery.

Preterm children do not have an increased risk for dyscalculia, new research suggests Posted: 01 Aug 2014 06:11 AM PDT Preterm children do not suffer from dyscalculia more often than healthy full-term children, experts say, contrary to previous studies. Unlike most other studies, the researchers took the children's IQ into consideration.

Scientists find new calorie-burning switch in brown fat Posted: 01 Aug 2014 06:11 AM PDT Biologists have identified a signaling pathway that switches on a powerful calorie-burning process in brown fat cells. The study sheds light on a process known as "brown fat thermogenesis," which is of great interest to medical researchers because it naturally stimulates weight loss and may also protect against diabetes.

Clues to flu's mechanisms uncovered: Scientists analyze how influenza-related proteins help infect cells Posted: 31 Jul 2014 05:16 PM PDT Scientists calculate the transformation of a protein associated with influenza and discover details of intermediate states that may be treated with new drugs.

Study of twins discovers gene mutation linked to short sleep duration Posted: 31 Jul 2014 05:15 PM PDT Researchers who studied 100 twin pairs have identified a gene mutation that may allow the carrier to function normally on less than six hours of sleep per night. The genetic variant also appears to provide greater resistance to the effects of sleep deprivation.

To combat obesity among U.S. Latina immigrants, cultural food patterns must be acknowledged Posted: 31 Jul 2014 01:00 PM PDT The factors that contribute to the problem of obesity among Latina immigrants in the U.S.A is the focus of new research. By compiling a systematic review of qualitative studies that focused on food patterns in Latina women, researchers have brought new light to this subject.

Popping pills to pushing needles: Prescription opioid abuse among young adults in NYC Posted: 31 Jul 2014 01:00 PM PDT Researchers have explored, within a social context, the drug-use and sexual experiences of young adult (ages 18-32) nonmedical prescription opioid users as they relate to risk for HIV and HCV transmission.

Political attitudes derive from body and mind: 'Negativity bias' explains difference between liberals and conservatives Posted: 31 Jul 2014 11:59 AM PDT Neither conscious decision-making or parental upbringing fully explain why some people lean left and others lean right, researchers say. A mix of deep-seated psychology and physiological responses are at the core of political differences.

C. difficile vaccine proves safe, 100 percent effective in animal models Posted: 31 Jul 2014 11:59 AM PDT An experimental vaccine protected 100 percent of animal models against the highly infectious and virulent bacterium, Clostridium difficile, which causes an intestinal disease that kills approximately 30,000 Americans annually.

New leads for liver disease treatments: Strict genomic partitioning by biological clock separates key metabolic functions Posted: 31 Jul 2014 11:59 AM PDT Much of the liver's metabolic function is governed by circadian rhythms -- our own body clock -- and researchers have now found two independent mechanisms by which this occurs.

The 'memory' of starvation is in your genes Posted: 31 Jul 2014 11:58 AM PDT Epigenetic 'experiments' -- changes resulting from external rather than genetic influences -- suggest that the body's physiological responses to hardship could be inherited, although the underlying mechanism has been a mystery. Now researchers have discovered a genetic mechanism that passes on the body's response to starvation to subsequent generations of worms, with potential implications for humans also exposed to starvation and other physiological challenges.

Insular cortex alterations in mouse models of autism Posted: 31 Jul 2014 11:58 AM PDT The insular cortex is an integral "hub," combining sensory, emotional and cognitive content. Not surprisingly, alterations in insular structure and function have been reported in many psychiatric disorders, such as anxiety disorders, depression, addiction and autism spectrum disorders. Scientists now describe consistent alterations in integrative processing of the insular cortex across autism mouse models of diverse etiologies.

A mathematical theory proposed by Alan Turing in 1952 can explain the formation of fingers Posted: 31 Jul 2014 11:58 AM PDT Researchers have shown that BMP and WNT proteins are the so-called 'Turing molecules' for creating embryonic fingers. Findings explain why polydactyly -- the development of extra fingers or toes -- is relatively common in humans, affecting up to one in 500 births, and confirms a fundamental theory first proposed by the founding father of computer science, Alan Turing, back in 1952.

'Rewired' mice show signs of longer lives with fewer age-related illnesses Posted: 31 Jul 2014 11:58 AM PDT While developing a new cancer drug, researchers discovered that mice lacking a specific protein live longer lives with fewer age-related illnesses. The mice, which lack the TRAP-1 protein, demonstrated less age related tissue degeneration, obesity, and spontaneous tumor formation when compared to normal mice. Their findings could change how scientists view the metabolic networks within cells.

Childhood coxsackie virus infection depletes cardiac stem cells, might compromise heart health in adults Posted: 31 Jul 2014 11:57 AM PDT There is epidemiological evidence that links type B coxsackie virus infection with heart disease, and research now suggests a mechanism by which early infection impairs the heart's ability to tolerate stress at later stages of life. CVB infection is very common and affects mostly children, and is often asymptomatic.

Disease mutations in mosaicism, rare condition where cells within the same person have different genetic makeup Posted: 31 Jul 2014 11:57 AM PDT Scientists have long speculated that mosaicism -- a biological phenomenon, in which cells within the same person have a different genetic makeup -- plays a bigger role in the transmission of rare disease mutations than is currently known. A study sheds new light on the frequency of mosaicism in genomic disorders and its influence on recurrence risk.

New mapping approach lets scientists zoom in and out as the brain processes sound Posted: 31 Jul 2014 11:54 AM PDT Researchers have mapped the sound-processing part of the mouse brain in a way that keeps both the proverbial forest and the trees in view. Their imaging technique allows zooming in and out on views of brain activity within mice, and it enabled the team to watch brain cells light up as mice "called" to each other.

Depression as a risk factor for dementia: Link is independent of dementia-related brain changes Posted: 30 Jul 2014 01:15 PM PDT A new study by neuropsychiatric researchers gives insight into the relationship between depression and dementia. The current study indicates that the association of depression with dementia is independent of dementia-related brain changes.

Target growth-driving cells within tumors, not fastest-proliferating cells Posted: 30 Jul 2014 10:31 AM PDT Growth-driving cancer cells may be better targets for therapies than cells that proliferate the fastest within the tumor, experts say. Of the many sub-groups of cells jockeying for supremacy within a cancerous tumor, the most dangerous may not be those that can proliferate the fastest, they explain in a new article.
