Study finds no substantial harm from primary care melanoma screening Posted: 08 Jul 2016 09:36 AM PDT Experts concerned that primary care screening for melanomas could lead to widespread misdiagnoses or overtreatment can take comfort in the results of a new study that found no such problems.

An epigenetic mechanism is involved in development of autoinflammatory diseases Posted: 08 Jul 2016 09:36 AM PDT Scientists have identified an epigenetic mechanism involved in the development of autoinflammatory diseases. The observed epigenetic changes open up possibilities for the development of novel biomarkers with clinical uses.

Where did it all go wrong? Scientists identify 'cell of origin' in skin cancers Posted: 08 Jul 2016 09:36 AM PDT Scientists have identified for the first time the 'cell of origin' -- in other words, the first cell from which the cancer grows -- in basal cell carcinoma, the most common form of skin cancer, and followed the chain of events that lead to the growth of these invasive tumors.

Two years and counting: Cannabis legalization efforts are starting to paint a clearer picture Posted: 08 Jul 2016 05:28 AM PDT What is the current landscape at the US federal level regarding cannabis legalization? A new report shows that from a public health perspective, the biggest concern -- the increase in youth consumption -- has apparently remained stable. From a financial perspective, it seems that it has been a success as well.

How plants sense electric fields Posted: 08 Jul 2016 05:20 AM PDT An international group of researchers has pinpointed the sensor plants use to sense electric fields. A beneficial side effect: their work could contribute to the understanding of how the Ebola virus enters human cells.

New work aiming to stop diabetes, a major global health challenge Posted: 08 Jul 2016 05:20 AM PDT A new study estimates the global prevalence of diabetes and anticipates future trends. According to the results, the world's adult population with diabetes increased from 108 million in 1980 to 422 millions in 2014 and if measures are not taken on time, this figure will exceed 700 millions in the next years.

Preconceptions predict coping, health outcomes Posted: 08 Jul 2016 05:20 AM PDT A study into chronic kidney disease is currently underway. The work shows that people who have chronic kidney disease (CKD) form pre-conceived beliefs about their illness which can impact their health.

Transplant drug may provide benefits after spinal cord injury Posted: 08 Jul 2016 05:19 AM PDT New research in mice indicates that a drug commonly used to suppress the immune system in recipients of organ transplants may also reduce tissue damage and neuropathic pain after spinal cord injury. Rapamycin, which is an inhibitor of the mammalian target of rapamycin (mTOR) signaling pathway, has a variety of cellular functions and is known to possess both immunosuppressant and anti-tumor properties.

Exercise training in heart failure: Shaping your proteins Posted: 08 Jul 2016 05:19 AM PDT Aerobic exercise training restored the cardiac protein quality control system in rats, showed a new study. More than 20 million people worldwide are estimated to have heart failure and this situation will get worse since the prevalence of heart failure will rise as the mean age of the population increases. The results of this study suggest that heart failure development is associated with disruption of cardiac protein quality control system and reinforce the importance of aerobic exercise training as a primary non-pharmacological therapy for treatment of heart failure patients.

Promising new methods for early detection of Alzheimer's disease Posted: 08 Jul 2016 05:19 AM PDT New methods to examine the brain and spinal fluid heighten the chance of early diagnosis of Alzheimer's disease. These findings may have important implications for early detection of the disease, the choice of drug treatment and the inclusion of patients in clinical trials.

Novel discovery improves profiling of acute myeloid leukemia patients for targeted therapies Posted: 08 Jul 2016 05:19 AM PDT Researchers have identified a set of genes, including DNMT3A, that could potentially be used to predict clinical outcomes of patients who suffer from a type of Acute Myeloid Leukemia (AML) associated with an FLT3 internal tandem duplication (FLT3-ITD) mutation.

Deadly bug strikes in a day Posted: 08 Jul 2016 05:17 AM PDT It's like something out of a horror movie -- a killer bug that goes through your nose and can kill you in 24 hours. What's worse is it could be lurking in your body without you even knowing it.

Exercise improves memory in breast cancer survivors Posted: 08 Jul 2016 05:17 AM PDT Moderate-to-vigorous physical activity is related to improved subjective memory in breast cancer survivors, who often complain about memory problems, reports a new study. It appears the physical activity alleviates stress and benefits women psychologically, which in turn aids their memory. Memory problems appear to be related to the high stress load cancer survivors experience, and may not be specific to chemotherapy or radiation treatments.

Increase in childhood, adult asthma linked to London's 1952 Great Smog Posted: 08 Jul 2016 05:17 AM PDT London's Great Smog of 1952 resulted in thousands of premature deaths and even more people becoming ill. The five December days the smog lasted may have also resulted in thousands more cases of childhood and adult asthma. Researchers studied how London's Great Smog affected early childhood health and the long-term health consequences. The results showed that the Great Smog event of 1952 likely still affects some people's health more than 60 years later.

Antidepressants: Treatment for bad marriages? Posted: 07 Jul 2016 02:23 PM PDT Psychiatrists nearly always responded with prescriptions for antidepressants when clients complained of bad marriages, according to a new study spanning 20 years at an American medical center. The assumption that people struggling with their marriages or other domestic issues are suffering from depression is not supported by the way depression is defined medically.

Athletes may have white matter brain changes six months after a concussion Posted: 07 Jul 2016 02:19 PM PDT New research finds white matter changes in the brains of athletes six months after a concussion, report investigators. The study involved 17 high school and college football players who experienced a sports-related concussion.

Researchers caution public about hidden risks of self-administered brain stimulation Posted: 07 Jul 2016 11:25 AM PDT Experts from the (cognitive) neuroscience research community warn about the risks involved in home use of transcranial direct current stimulation (tDCS), the application of electrical current to the brain.

New clue to how lithium works in the brain Posted: 07 Jul 2016 10:11 AM PDT Biologists have discovered a possible explanation for why lithium helps patients with bipolar disorder. In a study of C. elegans worms, the researchers identified a protein, known as BPNT1, which is inhibited by lithium, making the worms less active.

Nanodomains of reactive oxygen species control mitochondrial energy output Posted: 07 Jul 2016 10:11 AM PDT Using a new tool, researchers can study localized reactive oxygen species signals that control mitochondrial function in health and disease.

Energy saving filters for wastewater treatment created Posted: 07 Jul 2016 05:33 AM PDT Scientists have invented a new type of nanofilter that could reduce the energy needed to treat wastewater by up to five times. This breakthrough technology took about two years to develop and is now being commercialized across Asia.

New wave of antimalarial drugs in preparation Posted: 07 Jul 2016 05:32 AM PDT Malaria caused by the parasite Plasmodium falciparum remains a major public health problem worldwide. As a continuation of previous research targeting Hsp90, a universal molecular chaperone performing vital functions both in the parasite and in human cells, researcher have developed a strategy to identify molecules capable of inhibiting the parasite's protein and causing the destruction of the pathogen, without affecting mammalian cells.
