Clues to human molecular interactions Posted: 24 Jul 2015 12:18 PM PDT Scientists have unraveled how an important plant protein, known as TOPLESS, interacts with other molecules responsible for turning genes off. The findings in plants provide a general model across species for this type of gene silencing, which is linked to several vital biological functions in humans.

Know it's a placebo? Study shows the 'medicine' could still work Posted: 24 Jul 2015 10:56 AM PDT A new study shoes that under certain conditions, research participants who know a treatment they are receiving to ease pain is a placebo with no medical value, it still works.

Understanding why some latina women discontinue participation in cancer prevention outreach Posted: 24 Jul 2015 09:40 AM PDT It has long been known that rates of breast and cervical cancer screening among Latinas are low compared to rates for U.S. women overall. A new study found that age and fear of cancer diagnosis are among the reasons why Latina women do not continue participation following breast and cervical cancer education programs.

Clear connection between wireless devices and cancer, experts say Posted: 24 Jul 2015 09:39 AM PDT A metabolic imbalance caused by radiation from your wireless devices could be the link to a number of health risks, such as various neurodegenerative diseases and cancer, a recent study suggests.

Research analyzes impact of case volume on outcomes for DVT treatment Posted: 24 Jul 2015 07:54 AM PDT Patients who have lower extremity proximal deep vein thrombosis, or a blood clot in their leg, are increasingly undergoing minimally invasive catheter-based clot removal -- also referred to as catheter-directed thrombolysis -- rather than solely being treated with traditional blood-thinning medications. A study has found that a higher volume of CDT cases annually was associated with lower in-hospital mortality rates and lower intracranial hemorrhage.

Brain structure reveals ability to regulate emotions Posted: 24 Jul 2015 07:54 AM PDT People diagnosed with a personality disorder may find it difficult to function in society due to difficulties in regulating emotions -- but also healthy individuals differ in how often they become irritated, angry or sad. Scientists have published a study where they show that the affected brain areas in people with a clinical diagnosis are also affected in healthy individuals.

Toxin from salmonid fish has potential to treat cancer Posted: 24 Jul 2015 06:37 AM PDT Pathogenic bacteria develop killer machines that work very specifically and highly efficiently. Scientists have solved the molecular mechanism of a fish toxin that could be used in the future as a medication to treat cancer.

Prostate cancer not caused by shift work, experts say Posted: 24 Jul 2015 06:37 AM PDT Shift work is widespread: between approximately one in five and one in six of the working population work shifts. Now new research shows, that in fact, shift workers do not develop prostate cancer more frequently than their colleagues who work during the day.

'Watch' helps surgeons minimize potential risks of all-inside meniscal repair Posted: 24 Jul 2015 06:37 AM PDT A 'Watch' has been issued regarding potential risks with anchor-based all-inside meniscal repairs. While all-inside techniques have many advantages, including shorter surgical time and reduced risk of damage to neurovascular tissues, potential drawbacks include risks of local soft-tissue irritation and implant migration or breakage.In particular, the 'Watch' offers important tips for successfully using FAST-FIX meniscal-repair devices produced by Smith & Nephew.

Patient satisfaction is good indicator of success after spinal surgery Posted: 24 Jul 2015 05:48 AM PDT Patient satisfaction ratings after surgery for spinal degenerative disease--especially in terms of reduced pain and disability--are a good indicator of the procedure's effectiveness, reports a new study.

For prostate cancer patients, risk-specific therapies now more the norm Posted: 24 Jul 2015 05:26 AM PDT After decades of overtreatment for low-risk prostate cancer and inadequate management of its more aggressive forms, patients are now more likely to receive medical care matched to level of risk, according to a study.

Premature birth linked to withdrawn personality Posted: 24 Jul 2015 05:25 AM PDT Adults born very premature are more likely to be socially withdrawn and display signs of autism, research shows. The results showed that the adults born very preterm scored highly for displaying a socially withdrawn personality, indicated by autistic features, neuroticism, introversion and decreased risk taking.

Prostate cancer: Scientists discover why some tumous are resistant to radiotherapy Posted: 24 Jul 2015 05:25 AM PDT Scientists believe they have identified how some tiny regulatory molecules in cells can make prostate cancers resistant to radiotherapy. It is hoped that this new development could pave the way for more effective treatments -- allowing a lower dose of radiotherapy to be used while prolonging the lives of thousands of men.

Diagnosis of psychiatric disorders not as important as outcomes Posted: 24 Jul 2015 05:25 AM PDT Nailing the diagnosis of a psychiatric disorder may not be important in prescribing effective treatment, according a clinical researcher. The National Institute of Mental Health estimates that nearly one in five Americans suffers from mental illnesses as defined in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders.

Scientists discover first 'DNA ambulance' Posted: 24 Jul 2015 05:17 AM PDT Researchers have discovered how severely damaged DNA is transported within a cell and how it is repaired. It's a discovery that could unlock secrets into how cancer operates.

Attention-control video game curbs combat vets' PTSD symptoms Posted: 24 Jul 2015 05:17 AM PDT A computerized attention-control training program significantly reduced combat veterans' preoccupation with - or avoidance of -- threat and attendant PTSD symptoms. By contrast, another type of computerized training, called attention bias modification - which has proven helpful in treating anxiety disorders - did not reduce PTSD symptoms. Researchers conducted parallel trials in which the two treatments were tested in US and Israeli combat veterans.

'Successful aging' linked to harmful drinking among over 50s Posted: 23 Jul 2015 04:05 PM PDT The over 50s who are 'successful agers' -- healthy, active, sociable, and well off -- are more at risk of harmful drinking than their less successful peers, concludes new research.
