Study evaluates sexual well-being in SCT survivors using sexual function assessment tools

New research ties preparative procedures and complications associated with blood or bone marrow transplantation (stem cell transplantation, SCT) with diminished sexual health in both men and women who have undergone the lifesaving procedure. Study data, published online today in Blood, the Journal of the American Society of Hematology, confirm chronic graft-versus-host disease, a serious complication that occurs when donor cells attack the recipient's cells, as a potential source of sexual dysfunction and are the first to demonstrate an association between total body irradiation and sexual dysfunction in men.

Findings bring scientists closer to establishing regenerative therapies for humans

Cells triggering tissue regeneration that are taken from one limb and grafted onto another acquire the molecular "fingerprint," or identity, of their new location, UC Irvine developmental biologists have discovered.

Share of young people affected by digital abuse has declined, shows survey

MTV and The Associated Press-NORC Center for Public Affairs Research today released the results of a new survey exploring the pervasiveness of digital abuse among teens and young adults, how it is affecting America's youth and how they're responding to it. According to the survey, trends show that the share of young people affected by digital abuse has declined since 2011, with less than half (49 percent) of those surveyed stating that they have experienced digital abuse, compared to 56 percent in 2011.

Study: Gene Expression Classifier test reduces unnecessary surgeries in thyroid nodule assessment

The latest study co-led by a CU School of Medicine researcher has confirmed that a Gene Expression Classifier (GEC) test can drastically reduce the problem of unnecessary surgeries in thyroid nodule assessment.

Diabetic patients may require higher doses of metformin to achieve same anti-cancer activity

A University of Colorado Cancer Center study published online this month in the journal Cell Cycle shows that breast cancer cell growth, motility and aggression is promoted by excess glucose, as experienced by patients with diabetes and metabolic syndrome.

Rice University research reveals 3-way genetic switch for cancer metastasis

Cancer researchers from Rice University have deciphered the operating principles of a genetic switch that cancer cells use to decide when to metastasize and invade other parts of the body. The study found that the on-off switch's dynamics also allows a third choice that lies somewhere between "on" and "off." The extra setting both explains previously confusing experimental results and opens the door to new avenues of cancer treatment.

Just 13 days in space may cause changes in eye structure, gene expression

Just 13 days in space may be enough to cause profound changes in eye structure and gene expression, report researchers from Houston Methodist, NASA Johnson Space Center, and two other institutions in the October 2013 issue of Gravitational and Space Research.

"One-two punch" disables tumors' defenses

An aggressive form of breast cancer known as "triple negative" is very difficult to treat: Chemotherapy can shrink such tumors for a while, but in many patients they grow back and gain resistance to the original drugs.

Whitehead Institute scientists identify novel Parkinson's disease drug target

Using a discovery platform whose components range from yeast cells to human stem cells, Whitehead Institute scientists have identified a novel Parkinson's disease drug target and a compound capable of repairing neurons derived from Parkinson's patients.

HIV-positive patients with high CD4 cell counts are not at increased risk for heart attacks

Patients who are HIV-positive and have high CD4 cell counts - or have a high number of white blood cells that fight infections - aren't at an increased risk for heart attacks compared to patients who are HIV-negative, according to a Kaiser Permanente study that appears in the current online issue of the Journal of Acquired Immune Deficiency Syndromes.

Scientists identify link between rare mutations in RINT1 gene and early onset breast cancer risk

An international team of scientists has identified an association between heritable, rare mutations in the RINT1 gene and increased risk of early onset breast cancer, according to research reported today (Oct. 24) at the American Society of Human Genetics 2013 annual meeting in Boston.

Researchers discover novel genetic cause of severe obesity

Researchers from the University of Cambridge have discovered a novel genetic cause of severe obesity which, although relatively rare, demonstrates for the first time that genes can reduce basal metabolic rate - how the body burns calories.

Common food additive can block new strain of avian influenza virus

A common food additive can block a deadly new strain of avian influenza virus from infecting healthy cells, report researchers at the University of Illinois at Chicago College of Medicine in the online journal, PLOS ONE.

LCSB researchers publish current knowledge about the genetic, molecular causes of PD

Parkinson's disease continues to puzzle physicians and biologists alike - even though it is well-established that symptoms like muscle tremors, rigidity, and, during the final stages, immobility can all be traced back to the death of a certain type of brain cell called a dopaminergic neuron. The underlying cause of this cellular death is a complex web of interrelated genetic molecular processes as well as external factors, most of the details of which are well-known. But how the various factors correlate and influence each other continues to elude the scientific community.

Study reveals that tumors factors inhibit repair of damaged muscle fibers during cancer wasting

A new study reveals that tumors release factors into the bloodstream that inhibit the repair of damaged muscle fibers, and that this contributes to muscle loss during cancer wasting.

Researchers discover potential method to identify TBI using positron PET scans

Accurately diagnosing traumatic brain injuries (TBI) and concussions is difficult, as standard CT or MRI scans can't see most changes to the brain caused by these injuries.

Study shows plant sterols appear to prevent onset of Alzheimer's disease

It's no secret that many of the phytochemicals in fruit and vegetables have a positive effect on our health. For instance, plant sterols (also known as phytosterols) help to lower cholesterol levels. According to a new study by researchers at Saarland University, they also appear to prevent the onset of Alzheimer's disease.

Scientists find disparities in regulation of transposons between humans and non-human primate cells

Researchers at the Salk Institute for Biological Studies have, for the first time, taken chimpanzee and bonobo skin cells and turned them into induced pluripotent stem cells, a type of cell that has the ability to form any other cell or tissue in the body.

Unique approach to help discover how cell changes shape in response to topographies

Cells in the human body change shape as they crawl, split, or cling to other surfaces, but while the scientific literature is filled with examples of how cell shapes shift in response to things they touch, little is known about the rules that govern these changes. And there has been no high-throughput way to systematically test different topologies against different types of cells to optimize the surface of something like a medical implant.

BUSM researchers capture images of channels that direct proteins to right place in cell membranes

Similar to passengers on an urban transit system, every protein made in the cell has a specific destination and function. Channels in cell membranes help direct these proteins to their appropriate target. Researchers at Boston University School of Medicine and their colleagues have now captured images of these channels as they open to allow proteins to pass through a membrane, while the proteins are being made.
