Study: Cash to stay in school did not reduce HIV risk among young women in South Africa

A Phase III, individually randomized trial has found conditional cash transfers for school attendance did not reduce the risk of HIV among high-school aged women in South Africa, investigators from the HIV Prevention Trials Network (HPTN) reported today at the 8th International AIDS Society (IAS) Conference on HIV Pathogenesis, Treatment and Prevention in Vancouver, Canada.

New model helps to answer longstanding question in cancer science

A paper published today in the Proceedings of the National Academy of Sciences argues against the commonly held "accumulation of mutations" model of oncogenesis in favor of a model that depends on evolutionary pressures acting on populations of cells.

Researchers design virtual IPE curriculum for students in medical and nursing schools

The Institute of Medicine has identified interprofessional education (IPE) as a key innovation for achieving the triple aim of better care, better outcomes and reduced health care costs. Yet, a shortage of qualified faculty and difficulty with aligning learners' schedules often prevent sustainable and scalable IPE.

Dietary phosphate appears to cause spikes in blood phosphorus levels

Phosphates artificially added to dairy and cereal products appear to cause bigger spikes in blood phosphorus levels than naturally occurring phosphates, potentially putting harmful stress on kidneys. Too much dietary phosphate stiffens blood vessels, enlarges the heart and is bad for bones, but a new study by Houston Methodist researchers suggests it matters where the phosphates come from.

Common environmental chemicals may act separately or together to increase risk of cancer

Common environmental chemicals assumed to be safe at low doses may act separately or together to disrupt human tissues in ways that eventually lead to cancer, according to a task force of nearly 200 scientists from 28 countries, including one from Oregon State University.

New CHLA study uncovers baseline characteristics of transyouth seeking care for gender dysphoria

Johanna Olson, MD, and her colleagues at Children's Hospital Los Angeles, provide care for the largest number of transyouth in the U.S. and have enrolled 101 patients in a study to determine the safety and efficacy of treatment that helps patients bring their bodies into closer alignment with their gender of identity.

HOPE VI community revitalization project motivates exercise in Birmingham, Ala., neighborhood

When the HOPE VI community revitalization project in the disadvantaged Birmingham, Ala., neighborhood of Ensley reached the phase of building walking and biking paths, green spaces, and improved lighting in 2010, two things happened, according to a new study: First, residents developed specific expectations that leisure exercise would become more plausible, and then they followed through and got out there.

Researchers devise way to induce protective immunity in mice against influenza viruses

A vaccine that protects against a wide variety of influenza viruses (a so-called universal flu vaccine) is a critical public health goal given the significant rates of illness and death caused by seasonal influenza and the potentially devastating effects of a pandemic influenza strain.

Aging may trigger adaptive response to offset effects of oxidative stress on blood vessels

Although the causes of many age-related diseases remain unknown, oxidative stress is thought to be the main culprit. Oxidative stress has been linked to cardiovascular and neurodegenerative diseases including diabetes, hypertension and age-related cancers. However, researchers at the University of Missouri recently found that aging actually offered significant protection against oxidative stress.

Men gain weight after they become dads, new Northwestern Medicine study finds

All those leftover pizza crusts you snatch from your kids' plates add up. Men gain weight after they become fathers for the first time whether or not they live with their children, reports a large, new Northwestern Medicine study that tracked the weight of more than 10,000 men from adolescence to young adulthood.

Study reveals potential new therapeutic target for depression treatment

Increasing the levels of a signaling molecule found in the brain can positively alter response to stress, revealing a potential new therapeutic target for treatment of depression, UT Southwestern Medical Center researchers said.

New study suggests novel ways to treat serous retinal detachment

Wet age-related macular degeneration (AMD) is the leading cause of severe vision loss in older individuals. AMD and other serious chronic eye problems that affect younger individuals result when fluid accumulates abnormally under or within the retina. A new study published in The American Journal of Pathology shows for the first time that the release of substances from mast cells may be a causal factor in this type of eye pathology, and inhibitors of this release may offer new ways to treat serous retinal detachment.

ER physicians can identify patients at risk of future drinking-related trauma with 10-point questionnaire

Emergency room physicians treating patients with alcohol-related trauma can better identify those at risk of future drinking-related trauma with a 10-point questionnaire rather than the standard blood alcohol content test, according to a study in The Journal of the American Osteopathic Association.

Losing single night of sleep could alter genes that control biological clocks in cells

Swedish researchers at Uppsala University and the Karolinska Institute have found that genes that control the biological clocks in cells throughout the body are altered after losing a single night of sleep, in a study that is to be published in the Journal of Clinical Endocrinology and Metabolism.

Synthetic sugar could be latest weapon against superbugs

A special type of synthetic sugar could be the latest weapon in the fight against superbugs. A team of scientists from The University of Queensland and Queensland biotechnology company Alchemia have discovered a potential new class of antibiotics inspired by sugar molecules produced by bacteria.

Researchers use iPSCs to explore new treatments for kidney disease

One promising way to treat diseased or damaged kidneys is cell therapies that include the transplantation of renal progenitor cells, which can then develop into the cells needed for full recovery. Acquiring a sufficient number of progenitor cells has been difficult, however, which is why scientists have considered induced pluripotent stem cells (iPSCs), since they can be expanded at significantly high levels and then differentiated into the progenitors.
