New strategies needed to encourage male cancer survivors to consider future fertility

Pioneering research presented at the Fertility 2013 conference today (Thursday 3 January 2013) shows that a large proportion of male cancer patients are missing out on appropriate fertility advice.

Sperm banking is routinely recommended for all men diagnosed with cancer who are at risk of long-term infertility, caused by treatment such as chemotherapy and radiotherapy.

GW professor discovers new information in the understanding of autism and genetics

WASHINGTON (Jan. 3, 2012) – Research out of the George Washington University (GW), published in the journal Proceedings of the National Academy of Sciences (PNAS), reveals another piece of the puzzle in a genetic developmental disorder that causes behavioral diseases such as autism. Anthony-Samuel LaMantia, Ph.D., professor of pharmacology and physiology at the GW School of Medicine and Health Sciences (SMHS) and director of the GW Institute for Neuroscience, along with post-doctoral fellow Daniel Meechan, Ph.D.

Smile: Gingivitis bacteria manipulate your immune system so they can thrive in your gums

A new research report published in the Journal of Leukocyte Biology shows how the bacteria known for causing gum disease--Porphyromonas gingivalis--manipulates the body's immune system to disable normal processes that would otherwise destroy it. Specifically, the report shows that this pathogen prompts the production of the anti-inflammatory molecule Interleukin-10 (IL-10). This, in turn, inhibits the function of T-cells, which would otherwise help to protect the host from this particular microbial infection.

Disinfection caps cut CLABSI cases in half

Washington, DC, January 3, 2013 -- Central line-associated bloodstream infections (CLABSI) dropped by 52 percent when an alcohol-impregnated disinfection cap was used instead of standard scrubbing protocol, according to a new study published in the January issue of the American Journal of Infection Control, the official publication of the Association for Professionals in Infection Control and Epidemiology (APIC).

Scientists pinpoint molecular signals that make some women prone to miscarriage

The research, carried out at Imperial College London and the University of Warwick, suggests these signals could be targets for drugs that would help prevent miscarriage in women who are particularly vulnerable.

At the start of pregnancy, the fertilised embryo must embed itself in the lining of the uterus. The uterus is only receptive to embryos for a few days in each menstrual cycle, ensuring that embryos can only implant at the right stage of development. Currently scientists know only a few details about the biological processes that control when an embryo can be implanted.

Cholesterol medicine affects energy production in muscles

Up to 75 per cent of patients who take statins to treat elevated cholesterol levels may suffer from muscle pain. Scientists at the Center for Healthy Aging at the University of Copenhagen have now identified a possible mechanism underlying this unfortunate side effect. The results have just been published in the well-reputed Journal of American College of Cardiology.

Biologists unlock 'black box' to underground world

A BYU biologist is part of a team of researchers that has unlocked the "black box" to the underground world home to billions of microscopic creatures.

That first peek inside, recently published in the Proceedings of the National Academy of Sciences – one of the top three scientific journals in the world – may well explain how the number of species in an ecosystem changes the way it functions.

Study: Generational changes cause drop in US support for school prayer

There's a saying that goes, "as long as there are tests, there will be prayer in public schools." At one time, that likely reflected a fairly uniform view about school prayer: that despite what federal law said about the practice, religious Americans by and large approved of it.

A new study, however, paints a more complicated picture of attitudes toward school prayer over the last four decades, finding sharp differences in school-prayer support between different generations and their religious denominations.

Food for friendship: Bonobos share with strangers in exchange for company

Bonobos voluntarily share food and will even forego their own meals for a stranger, but only if the recipient offers them social interaction, according to research published January 2 by Jingzhi Tan and Brian Hare of Duke University.

For those short on time, aerobic, not resistance, exercise is best bet for weight, fat loss

BETHESDA, Md. (Jan. 2, 2012)—A new study led by North Carolina researchers has found that when it comes to weight- and fat loss, aerobic training is better than resistance training. The study is believed to the largest randomized trial to directly compare changes in body composition induced by comparable amounts of time spent doing aerobic and resistant training, or both in combination, among previously inactive overweight or obese non-diabetic adults.

Complaint: Shortened penis following prostate cancer treatment

A small percentage of men in a prostate cancer study complained that their penis seemed shorter following treatment, with some saying that it interfered with intimate relationships and caused them to regret the type of treatment they chose.

Common data determinants of recurrent cancer are broken, mislead researchers

In order to study the effectiveness or cost effectiveness of treatments for recurrent cancer, you first have to discover the patients in medical databases who have recurrent cancer. Generally studies do this with billing or treatment codes – certain codes should identify who does and does not have recurrent cancer. A recent study published in the journal Medical Care shows that the commonly used data determinants of recurrent cancer may be misidentifying patients and potentially leading researchers astray.

Previous studies on toxic effects of BPA couldn't be reproduced

Following a three-year study using more than 2,800 mice, a University of Missouri researcher was not able to replicate a series of previous studies by another research group investigating the controversial chemical BPA. The MU study is not claiming that BPA is safe, but that the previous series of studies are not reproducible. The MU study, published in the Proceedings of the National Academy of Sciences, also investigated an estrogenic compound found in plants, genistein, in the same three-year study.

Treating stable flies in pastures

This press release is available in Spanish.

U.S. Department of Agriculture (USDA) scientists are developing strategies to help livestock producers control stable flies, the most damaging arthropod pests of cattle in the United States.

Toward reducing the greenhouse gas emissions of the Internet and telecommunications

Amid growing concern over the surprisingly large amount of greenhouse gas produced by the Internet and other telecommunications activities, researchers are reporting new models of emissions and energy consumption that could help reduce their carbon footprint. Their report appears in ACS' journal Environmental Science & Technology.
