Gene therapy bolsters enzyme activity to combat Alzheimer's disease in mice Posted: 03 Dec 2013 01:15 PM PST Scientists have identified an enzyme that can halt or possibly even reverse the build-up of toxic protein fragments known as plaques in the brains of mice with Alzheimer's disease.

Many patients have trouble identifying their medications Posted: 03 Dec 2013 11:42 AM PST People who identified their medication by shape, size or color instead of name had poorer adherence and an increased risk of hospitalization, finds a recent study.

Alzheimer's risk gene may begin to affect brains in childhood, research shows Posted: 03 Dec 2013 10:38 AM PST People who carry a high-risk gene for Alzheimer's disease show changes in their brains beginning in childhood, decades before the illness appears, new research suggests.

1950s pandemic influenza virus remains a health threat, particularly to those under 50 Posted: 03 Dec 2013 09:49 AM PST Scientists have evidence that descendants of the H2N2 avian influenza A virus that killed millions worldwide in the 1950s still pose a threat to human health, particularly to those under 50.

Obesity, smoking increase risk after immediate breast reconstruction with implants Posted: 03 Dec 2013 09:47 AM PST New research findings confirm that factors such as smoking and obesity increase the odds of early implant loss in women who undergo mastectomy and immediate breast reconstruction with implants.

Manufacturing new gut to treat GI diseases Posted: 03 Dec 2013 08:22 AM PST Researchers grow extensive numbers of intestinal stem cells, then coax them to develop into different types of mature intestinal cells.

Prenatal exposure to alcohol disrupts brain circuitry: No safe level of drinking during pregnancy, neuroscientist says Posted: 03 Dec 2013 07:59 AM PST Prenatal exposure to alcohol severely disrupts major features of brain development that potentially lead to increased anxiety and poor motor function, conditions typical in humans with Fetal Alcohol Spectrum Disorders, say neuroscientists.

Current sound-localization theories turned 'on their ear' Posted: 03 Dec 2013 07:59 AM PST New research challenges the two dominant theories of how people localize sounds, explains why neuronal responses to sounds are so diverse and shows how sound can be localized, even with the absence of one half of the brain.

Dual protein knockout could lead to new male contraceptive Posted: 03 Dec 2013 06:16 AM PST A new male contraceptive could be on the horizon after scientists identified a novel way to block the transport of sperm during ejaculation.

Our pupils adjust as we imagine bright and dark scenes Posted: 03 Dec 2013 06:16 AM PST Conjuring up a visual image in the mind -- like a sunny day or a night sky -- has a corresponding effect on the size of our pupils, as if we were actually seeing the image.

New research shows promise for possible HIV cure Posted: 03 Dec 2013 06:16 AM PST Researchers have used radioimmunotherapy to destroy remaining human immunodeficiency virus (HIV)-infected cells in the blood samples of patients treated with antiretroviral therapy, offering the promise of a strategy for curing HIV infection.

Talk therapy may reverse biological changes in PTSD patients Posted: 03 Dec 2013 06:14 AM PST New research suggests that cognitive behavioral therapy for posttraumatic stress disorder (PTSD) not only reduces symptoms but also affects the underlying biology of this disorder.

Biological interactions make some malaria parasites specific to host species Posted: 02 Dec 2013 01:19 PM PST Researchers have discovered why the parasite that causes the deadliest form of malaria only infects humans.

Don't ignore hip pain: Impingement a growing problem among young, active Posted: 02 Dec 2013 12:20 PM PST Hip pain is no longer reserved for older adults. More and more young, active people are developing this problem, which often requires surgery to repair.

Do sports concussions really cause chronic traumatic encephalopathy? Posted: 02 Dec 2013 12:20 PM PST It's been widely reported that football and other contact sports increase the risk of a debilitating neurological condition called chronic traumatic encephalopathy (CTE). But a new study finds little evidence to support such a link.

US mothers from 1965 to 2010: more TV, less housework Posted: 02 Dec 2013 10:48 AM PST New research shows that mothers in the US are far less physically active than they were in previous decades and now spend more time engaged in sedentary activities like watching television than in cooking, cleaning and exercising combined. The research provides important insights into the nation's pervasive health problems such as childhood obesity and diabetes.

Newly discovered human peptide may become new treatment for diabetes Posted: 02 Dec 2013 10:46 AM PST There is new hope that diabetes might be thwarted. New research shows how a recently discovered human peptide, called humanin, could lead to new treatments for people living with diabetes. That's because research in mice and rats shows that a humanin analogue (a peptide molecularly similar to humanin) increases insulin secretion, leading to an increase in glucose metabolism within beta cells.

New report illustrates persistent global burden of anemia among high-risk populations Posted: 02 Dec 2013 09:15 AM PST Despite increasing efforts to diagnose and treat anemia worldwide, there remains a surprisingly large global burden of the disease, particularly among young children and women, according to a new report on trends in anemia between 1990 and 2010.

Oxygen levels affect effectiveness of anti-inflammatory therapies Posted: 02 Dec 2013 09:15 AM PST A new research discovery yields an important clue toward helping curb runaway inflammation. Oxygen levels play a critical role in determining the severity of the inflammatory response and ultimately the effectiveness of anti-inflammatory drugs. This research could have significant future benefits for patients with severe asthma, COPD, rheumatoid arthritis, pulmonary fibrosis and coronary artery disease.
