Finding identifies new mechanism that could contribute to the pathology of ALS

RNA molecules, used by cells to make proteins, are generally thought to be "silent" when stowed in cytoplasmic granules. But a protein mutated in some ALS patients forms granules that permit translation of stored RNAs, according to a study in The Journal of Cell Biology. The finding identifies a new mechanism that could contribute to the pathology of the disease.

New research reveals how high-protein diet reduces muscle loss when dieting

Building upon the discovery that a high-protein diet reduces muscle loss when dieting, a new research report published online in The FASEB Journal now helps explain why. Protein consumption slows the ubiquitin proteasome system, which is primarily responsible for degrading skeletal muscle.

Patients treated for traumatic eye socket injuries at academic medical centers fare well at far less cost

Adding to evidence that “high-volume” specialty care in busy teaching hospitals leads to efficiencies unavailable in community hospitals, a new study by Johns Hopkins researchers finds that patients undergoing repair of traumatic eye socket injuries at its busy academic medical center fared just as well at far less cost than those treated at all other Maryland hospitals.

Findings could have important implications for personalized treatment of colon cancer

A common observation in oncology is the phenomenon that a patient with a tumor receives a drug and responds very well, but after a few months the cancer comes back and is now resistant to previously administered chemotherapy. What happened? Many mechanisms contribute to explain this effect called "acquired resistance", but today the group Manel Esteller, Director of Epigenetics and Cancer Biology at the Bellvitge Biomedical Research Institute, ICREA researcher and Professor of Genetics at the University of Barcelona, describes in the official Journal of the National Cancer Research Center in the United States, The Journal of The National Cancer Institute, the existence of epigenetic differences that explain the lack of response of the tumor recurs.

Newly discovered receptor may help in early diagnosis and treatment for sepsis

Sepsis, or septicaemia, is a devastating disease that is difficult to diagnose early and for which treatment options are limited. The number of deaths from sepsis exceeds those from lung cancer, and from breast and bowel cancer combined.

Older HIV-positive men at higher risk of HPV that causes anal cancer

Human papillomavirus, or HPV, which can cause cervical cancer in women, is also known to cause anal cancer in both women and men. Now, a study led by researchers at the UCLA School of Nursing has found that older HIV-positive men who have sex with men are at higher risk of becoming infected with the HPVs that most often cause anal cancer.

Research findings pave new ways to treat gastrointestinal disorders

For those living with gastrointestinal disorders, such as ulcers or Crohn's disease, treatment often means quelling uncomfortable symptoms through medications or dietary changes. But what if one day treatment meant doing away with the old gut for a new gut free of inflamed or diseased tissues?

Cognitive behavioral therapy for PTSD affects underlying biology of the disorder

A new paper published in Biological Psychiatry suggests that cognitive behavioral therapy for posttraumatic stress disorder not only reduces symptoms but also affects the underlying biology of this disorder.

Presence of ERG protein in biopsied prostate tissue increases likelihood of cancer development

Researchers from Weill Cornell Medical College have shown that the presence of a particular protein in biopsied prostate tissue substantially increases the likelihood that cancer will develop in that organ. The discovery will likely help physicians decide how closely to monitor men potentially at risk for the cancer -- among the most confusing and controversial dilemmas in health care.

California scholar receives Wrawemeyer Award for Psychology for proposed somatic marker hypothesis

A California scholar who proposed that emotions play an integral role in human reasoning and decision-making has won the 2014 University of Louisville Grawemeyer Award for Psychology.

A new approach for treating colorectal cancer

Scientists and surgeons at Princess Margaret Cancer Centre have discovered a promising new approach to treating colorectal cancer by disarming the gene that drives self-renewal in stem cells that are the root cause of disease, resistance to treatment and relapse.

CTCs serve as clinical tool to determine patient’s response to chemotherapy

Scientists from Granada have demonstrated, for the first time, that detecting circulating tumour cells (CTCs) in blood and studying the presence of certain genetic markers in them is a technique that allows specialists to predict, with great precision, the response that advanced-cancer patients will have to chemotherapy, as well as the associated secondary effects they may suffer.

Patients undergoing eye trauma care fare equally well in teaching and community hospitals

Adding to evidence that "high-volume" specialty care in busy teaching hospitals leads to efficiencies unavailable in community hospitals, a new study by Johns Hopkins researchers finds that patients undergoing repair of traumatic eye socket injuries at its busy academic medical center fared just as well at far less cost than those treated at all other Maryland hospitals.

Scientists receive $12.5M NIH grant to continue research on targeted therapies for melanoma

Despite recent advances in therapy, melanoma remains the deadliest, most aggressive form of skin cancer as incidence rates continue to climb. Now, a team of melanoma scientists from The Wistar Institute and the University of Pennsylvania received a $12.5 M, five-year program project grant (P01) from the National Institutes of Health to continue trailblazing research on targeted therapies in melanoma.

New research suggests that Alzheimer's gene may begin to affect brains in childhood

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 from the Centre for Addiction and Mental Health suggests.

Gladstone scientist devise new molecular sensor that can detect MS at earliest stages

For some, the disease multiple sclerosis attacks its victims slowly and progressively over a period of many years. For others, it strikes without warning in fits and starts. But all patients share one thing in common: the disease had long been present in their nervous systems, hiding under the radar from even the most sophisticated detection methods. But now, scientists at the Gladstone Institutes have devised a new molecular sensor that can detect MS at its earliest stages-even before the onset of physical signs.

Scientists identify enzyme that could lead to better treatment of Alzheimer's disease

St. Jude Children's Research Hospital 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. The research appeared in a recent edition of the scientific journal Nature Communications.

Exercise may benefit older people with dementia

Exercise may benefit older people with dementia by improving their cognitive functioning and ability to carry out everyday activities, according to a new systematic review published in The Cochrane Library. However, the authors of the review did not see any clear effect of exercise on depression in older people with dementia and say that more evidence is needed to understand how exercise could reduce the burden on family caregivers and health systems.

Obese patients receive needless respiratory treatment

Research from the USA shows that a substantial proportion of obese patients are prescribed bronchodilators, even after spirometry indicates a lack of lung obstruction.

Social defeat links past trauma to current psychosis

The feeling of social defeat may be responsible for the link between childhood trauma and psychosis, research suggests.
