Older men with low levels of vitamin B12 may have higher risk of fractures

Older men who have low levels of vitamin B12 have a higher risk of having fractures. These are the findings of researchers at the Sahlgrenska Academy as a part of an international study of a total of 1000 older men.

FoundationOne Heme identifies clinically actionable genomic alterations in multiple myeloma cases

Foundation Medicine today announced new data from a pilot study demonstrating that its fully informative genomic profile for hematologic malignancies, FoundationOne Heme, identified both novel and previously reported clinically actionable genomic alterations in multiple myeloma cases. These data were presented in an oral presentation titled Pilot Study To Evaluate The Prevalence Of Actionable Oncogenic Mutations In Patients With Relapsed Refractory Multiple Myeloma (abstract number 755) by Alexander Lesokhin, M.D., medical oncologist, Memorial Sloan-Kettering Cancer Center, at the 55th American Society of Hematology Annual Meeting in New Orleans.

Study finds large degree of genetic variation amongst M. tuberculosis in humans in Zambia

In Zambia, the incidence of all forms of human tuberculosis is estimated to be 444 per 100,000. There is also a high incidence of HIV and AIDS in the country. In the Kafue area, a high incidence of Mycobacterium bovis in both cattle and the Kafue lechwe antilope has been detected. This bacterium can infect humans and has been found in humans in the studied region of Namwala. Mycobacterium tuberculosis, which is the main cause of human tuberculosis, has also been detected in cattle in this region.

Researchers identify 10 genes that may signify trifecta of benefits for women with ovarian cancer

Researchers in the Women's Cancer Program at Cedars-Sinai's Samuel Oschin Comprehensive Cancer Institute have identified a series of 10 genes that may signify a trifecta of benefits for women diagnosed with ovarian cancer and ultimately reflect improved survival outcomes.

Scientists devise method to measure forces in 3D tissues, living embryos

As embryonic tissue develops, cells push and pull on each other, and they must do so correctly for the tissue to develop properly. Now scientists at Harvard University have devised the first method to measure these forces in three-dimensional (3D) tissues and living embryos.

Drugs that enhance oxidative stress kill rhabdomyosarcoma tumor cells

Drugs that enhance a process called oxidative stress were found to kill rhabdomyosarcoma tumor cells growing in the laboratory and possibly bolstered the effectiveness of chemotherapy against this aggressive tumor of muscle and other soft tissue. The findings are the latest from the St. Jude Children's Research Hospital-Washington University Pediatric Cancer Genome Project and appear in the December 9 edition of the scientific journal Cancer Cell.

Study reveals that germ-free mice are susceptible to infection with foodborne pathogen

When it comes to fighting off pathogens like Listeria, your best allies may be the billions of microorganisms that line your gut, according to new research published in mBio-, the online open-access journal of the American Society for Microbiology.

Scientists discover novel chemical lurking in atmosphere that appears to be LLGHG

Scientists from U of T's Department of Chemistry have discovered a novel chemical lurking in the atmosphere that appears to be a long-lived greenhouse gas (LLGHG). The chemical - perfluorotributylamine (PFTBA) - is the most radiatively efficient chemical found to date, breaking all other chemical records for its potential to impact climate.

New drug that blocks defective gene can arrest Waldenstrom's Macroglobulinemia in animal models

In nearly one-third of patients with Waldenstrom's Macroglobulinemia, a specific genetic mutation switches on the disease, and a new drug that blocks the defective gene can arrest the disease in animal models, researchers at Dana-Farber Cancer Institute and allied institutions will report at the 2013 annual meeting of the American Society of Hematology.

Scientists discover how lymphotoxin controls production of immunoglobulins in gut

Lymphotoxin is a cytokine, or intercellular messenger, and plays an important role in the immunological balance of the gastrointestinal tract. It regulates the immune system of the digestive tract, which is made up of immune cells, immunoglobulins (antibodies) as well as intestinal bacteria.

New demographic data unveils extraordinary diversity of aging processes

Despite aging being one the hottest topic in the media recently, scientists have no coherent explanation for it. New demographic data on humans, animals and plants for the first time unveil such an extraordinary diversity of aging processes that no existing evolutionary theory can account for. Both life spans and mortalities vary from species to species.

Concussive brain injuries can lead to depressive behaviors later in life

A head injury can lead immune-system brain cells to go on "high alert" and overreact to later immune challenges by becoming excessively inflammatory - a condition linked with depressive complications, a new animal study suggests.

UC Santa Barbara professor finds method for measuring cellular forces that shape tissues, organs

Like tiny construction workers, cells sculpt embryonic tissues and organs in 3D space. This task is complicated and requires constant communication between cells to coordinate their actions and generate the forces that will shape their environment into complex tissue morphologies.

Researchers develop new technique to cure human diseases caused by misfolded protein molecules

A team led by a longtime Oregon Health & Science University researcher has demonstrated in mice what could be a revolutionary new technique to cure a wide range of human diseases - from cystic fibrosis to cataracts to Alzheimer's disease - that are caused by "misfolded" protein molecules.

Researchers evaluate effect of zinc supplementation on aluminum-induced neurotoxicity

Studies have shown that aluminum neurotoxicity can likely affect learning and memory function, and a diet containing 100-200 mg/kg zinc is adequate for maintaining learning and memory function in rats.

Shifts in zinc's location could be exploited for early diagnosis of prostate cancer

Zinc, an essential nutrient, is found in every tissue in the body. The vast majority of the metal ion is tightly bound to proteins, helping them to perform biological reactions. Tiny amounts of zinc, however, are only loosely bound, or "mobile," and thought to be critical for proper function in organs such as the brain, pancreas, and prostate gland. Yet the exact roles the ion plays in biological systems are unknown.
