Investigational oral regimen for hepatitis C shows promise Posted: 27 Aug 2013 05:44 PM PDT In a study of an all-oral drug regimen, a majority of volunteers with liver damage due to hepatitis C virus infection were cured following a six-month course of therapy that combined an experimental drug, sofosbuvir, with the licensed antiviral drug ribavirin. The results showed that the regimen was highly effective in clearing the virus and well tolerated in a group of patients who historically have had unfavorable prognoses.

Size of personal space is affected by anxiety Posted: 27 Aug 2013 05:43 PM PDT The space surrounding the body (known by scientists as 'peripersonal space'), which has previously been thought of as having a gradual boundary, has been given physical limits by new research into the relationship between anxiety and personal space.

New approach to celiac testing identifies more at risk Posted: 27 Aug 2013 05:40 PM PDT Researchers have developed a new approach to detecting celiac disease, revealing this immune disorder is far more common than previously recognized.

Conspiracy theories may put children's health at risk Posted: 27 Aug 2013 05:40 PM PDT A belief in conspiracy theories may influence parents' intentions to have their children vaccinated against diseases such as measles.

Three subtypes of gastric cancer suggest different treatment approaches Posted: 27 Aug 2013 05:40 PM PDT Stomach cancer, one of the leading causes of cancer death worldwide, actually falls into three broad subtypes that respond differently to currently available therapies, according to researchers.

Genetic variant associated with coronary heart disease in type 2 diabetes Posted: 27 Aug 2013 05:39 PM PDT Scientists have identified a previously unknown genetic variant associated with an increased risk of coronary heart disease in type 2 diabetic patients. This discovery has the potential to lead to the development of new treatments for in diabetic patients.

Biomaterial, pharmacy researchers develop polymer to help oral medications reach bloodstream Posted: 27 Aug 2013 05:39 PM PDT Research on new polymer additives that enhance the ability of orally administered drugs will result in greater effectiveness and fewer side effects, researchers say.

Why are some cells more cancer prone? Posted: 27 Aug 2013 01:05 PM PDT Cells in the body wear down over time and die. In many organs, like the small intestine, adult stem cells play a vital role in maintaining function by replacing old cells with new ones. Learning about the nature of tissue stem cells can help scientists understand exactly how our organs are built, and why some organs generate cancer frequently, but others only rarely.

Fractions gain traction with real-life models Posted: 27 Aug 2013 01:05 PM PDT For children to understand math, teachers must constantly make the connection between abstract numbers and real world examples, new research shows.

Winter depression not as common as many think Posted: 27 Aug 2013 10:50 AM PDT New research suggests that getting depressed when it's cold and dreary outside may not be as common as is often believed.

Study relies on twins and their parents to understand height-IQ connection Posted: 27 Aug 2013 10:50 AM PDT The fact that taller people also tend to be slightly smarter is due in roughly equal parts to two phenomena -- the same genes affect both traits and taller people are more likely than average to mate with smarter people and vice versa -- according to a new study.

Botox not just for wrinkles Posted: 27 Aug 2013 10:47 AM PDT Botox is best known as a cosmetic treatment for frown lines, but the drug also effectively treats the after effects of Bell's palsy and other serious facial nerve problems.

New surgical tool may help sleep apnea sufferers Posted: 27 Aug 2013 10:47 AM PDT A researcher's innovative use of a new tool may make surgery a more viable option for sufferers of obstructive sleep apnea/hypopnea syndrome (OSAHS).

Mystery in blot clotting disorder solved Posted: 27 Aug 2013 10:47 AM PDT Fifteen years ago, a hematologist came an expert with a puzzle: Multiple generations of an East Texas family suffered from a moderately severe bleeding disorder, but it wasn't hemophilia.

Low inflammation may explain healthy metabolic status in some obese people Posted: 27 Aug 2013 10:47 AM PDT Reduced levels of inflammation may explain how some obese people are able to remain metabolically healthy, according to a recent study.

Early diabetes interventions may also reduce heart disease risk Posted: 27 Aug 2013 10:47 AM PDT Two treatments that slow the development of diabetes also may protect people from heart disease, according to a recent study.

Evaluating medical research: New treatments better than standard ones just over half the time Posted: 27 Aug 2013 09:29 AM PDT Scientists report that on average new treatments work better than existing ones just over half the time. And, from an ethical and scientific perspective, that's evidence that the randomized controlled trial system is working, they say.

Apoptosis triggers replication of common viruses Posted: 27 Aug 2013 09:29 AM PDT Researchers have found that an alternate, "escape" replication process triggered by apoptosis -- the process of cell death or "cell suicide" -- appears to be common in human herpesviruses. The findings have implications for better understanding of viruses and of disease conditions and treatments, like chemotherapy, that stimulate apoptosis.

Generational shift in attitudes among young soccer players towards gay teammates Posted: 27 Aug 2013 09:29 AM PDT Young soccer players on the verge of becoming professionals are now much more likely to be supportive of gay teammates than a decade ago, according to new research.

Molecular process behind form of non-syndromic deafness identified Posted: 27 Aug 2013 09:28 AM PDT Researchers identify an underlying molecular process that causes a genetic form of non-syndromic deafness in a new study that also suggests affected families may be at risk of damage to other organs.

Tumor suppressor may actually fuel aggressive leukemia Posted: 27 Aug 2013 09:28 AM PDT New research suggests that blocking a protein normally credited with suppressing leukemia may be a promising therapeutic strategy for an aggressive form of the disease called acute myeloid leukemia. The protein scientists targeted is a transcription factor known as RUNX1, which also plays an important role in helping regulate the normal development of blood cells.

Scientists prevent preterm birth caused by gene-environment interactions in mice Posted: 27 Aug 2013 09:28 AM PDT New research provides evidence that gene-environment interactions are a major contributor to preterm birth and that using a combinatory treatment strategy can prevent preterm delivery in a mouse model. Scientists say their study provides important new insights into a major global health problem -- one that remains stubbornly persistent in the United States.

Promising therapeutic target for hard-to-treat brain tumor Posted: 27 Aug 2013 09:27 AM PDT Researchers say they have found a specific protein in nearly 100 percent of high-grade meningiomas — the most common form of brain tumor — suggesting a new target for therapies for a cancer that does not respond to current chemotherapy.

Researcher controls colleague's motions in first human brain-to-brain interface Posted: 27 Aug 2013 09:27 AM PDT Researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.

Hodgkin lymphoma treatment linked to possible risk of stomach cancer Posted: 27 Aug 2013 09:27 AM PDT Hodgkin lymphoma survivors who received certain radiation and chemotherapy regimens were at increased risk of subsequently developing stomach cancer, according to a new study.

Humans experiencing increased exposure to aluminium and its predicted to get worse Posted: 27 Aug 2013 08:21 AM PDT Aluminium - the most abundant metal and third most abundant element of the Earth's crust - has no known biological function and is a recognized environmental toxin. Human exposure to aluminium is implicated in a number of chronic diseases, including bone disease, auto-immune conditions, cancer and neurodegenerative diseases.

Stem cells may do best with a little help from their friends Posted: 27 Aug 2013 08:19 AM PDT Like volunteers handing out cups of energy drinks to marathon runners, specially engineered "helper cells" transplanted along with stem cells can dole out growth factors to increase the stem cells' endurance, at least briefly, researchers report. Their study is believed to be the first to test the helper-cell tactic, which they hope will someday help to overcome a major barrier to successful stem cell transplants.

Long-term memory stored in the cortex Posted: 27 Aug 2013 06:16 AM PDT 'Where' and 'how' memories are encoded in a nervous system is one of the most challenging questions in biological research. The formation and recall of associative memories is essential for an independent life. The hippocampus has long been considered a centre in the brain for the long-term storage of spatial associations. Now, researchers have provided the first experimental evidence that a specific form of memory associations is encoded in the cerebral cortex and is not localized in the hippocampus as described in most neuroscience textbooks. The new study is a game changer since it strongly suggests that the motor cortical circuits itself, and not the hippocampus, is used as memory storage.

Drug blocks light sensors in eye that may trigger migraine attacks Posted: 27 Aug 2013 06:14 AM PDT For many migraine sufferers, bright lights are a surefire way to exacerbate their headaches. And for some night-shift workers, just a stroll through a brightly lit parking lot during the morning commute home can be enough to throw off their body's daily rhythms and make daytime sleep nearly impossible. But a new molecule that selectively blocks specialized light-sensitive receptors in the eyes could help both these groups of people, without affecting normal vision.

Perception of marijuana as a 'safe drug' is scientifically inaccurate, finds review of teen brain studies Posted: 27 Aug 2013 06:14 AM PDT The nature of the teenage brain makes users of cannabis amongst this population particularly at risk of developing addictive behaviors and suffering other long-term negative effects, according to researchers who reviewed over 120 studies.

Novel approach to gene regulation can activate multiple genes simultaneously Posted: 27 Aug 2013 06:13 AM PDT By creating a powerful new gene regulation system called CRISPR-on, researchers now have the ability to increase the expression of multiple genes simultaneously and precisely manipulate each gene's expression level. The system is effective in both mouse and human cells as well as in mouse embryos.
