Hormonal therapy for transsexualism safe and effective

Hormonal therapy for transsexual patients is safe and effective, a multicenter European study indicates. The results will be presented Saturday at The Endocrine Society's 95th Annual Meeting in San Francisco.

Transsexual individuals who seek treatment may feel as though they were born the wrong gender. Surgical and hormonal therapies are available to help these people change their external characteristics to match their internal image of themselves.

Similar genetic variation found in overweight newborns and adults

Similar genetic variations occur in both overweight newborns and obese adults, a large study finds. The results will be presented Tuesday at The Endocrine Society's 95th Annual Meeting in San Francisco.

Timing of calcium and vitamin D supplementation may affect how bone adapts to exercise

Taking calcium and vitamin D before exercise may influence how bones adapt to exercise, according to a new study. The results will be presented on Tuesday at The Endocrine Society's 95th Annual Meeting in San Francisco.

New risk score could lead to earlier prevention of type 2 diabetes in African Americans

Researchers have developed a risk assessment scoring system that they believe may better identify certain adults-– especially African Americans-– at high risk of developing type 2 diabetes, heart disease and stroke than does the current system of diagnosing the metabolic syndrome. The results will be presented Tuesday at The Endocrine Society's 95th Annual Meeting in San Francisco.

Tackling a framework for surgical innovation

NEW YORK (June 18, 2013)-- An international team of investigators co-led by Weill Cornell Medical College is offering a new framework for evidence-based surgery and device research, similar to the kind of risk and benefit analysis used in evidence-based medicine.

"Currently, there is no dynamic research framework to systematically detect devices and surgeries that don't offer any benefits to patients or may even be harmful," says co-lead investigator Dr. Art Sedrakyan of Weill Cornell Medical College.

Chemical probe confirms that body makes its own rotten egg gas, H2S, to benefit health

A new study confirms directly what scientists previously knew only indirectly: The poisonous "rotten egg" gas hydrogen sulfide is generated by our body's growing cells.

Hydrogen sulfide, or H2S, is normally toxic, but in small amounts it plays a role in cardiovascular health.

In the new study, chemists developed a chemical probe that reacts and lights up when live human cells generate hydrogen sulfide, says chemist Alexander R. Lippert, Southern Methodist University, Dallas. The discovery allows researchers to observe the process through a microscope.

Herbal extract boosts fruit fly lifespan by nearly 25 percent, UCI study finds

Irvine, Calif., June 18, 2013 — The herbal extract of a yellow-flowered mountain plant long used for stress relief was found to increase the lifespan of fruit fly populations by an average of 24 percent, according to UC Irvine researchers.

But it's how Rhodiola rosea, also known as golden root, did this that grabbed the attention of study leaders Mahtab Jafari and Sam Schriner. They discovered that Rhodiola works in a manner completely unrelated to dietary restriction and affects different molecular pathways.

Small dam construction to reduce greenhouse emissions is causing ecosystem disruption

CORVALLIS, Ore. – Researchers conclude in a new report that a global push for small hydropower projects, supported by various nations and also the Kyoto Protocol to reduce greenhouse gas emissions, may cause unanticipated and potentially significant losses of habitat and biodiversity.

Gel or whitening? Consumer choice and product organization

Consumers choose lower-priced products and are more satisfied with their purchase when products are organized by benefits instead of features, according to a new study in the Journal of Consumer Research.

"It matters whether products are organized by features or benefits. Simply changing the way the same set of products is organized impacts how consumers process information and make choices," write authors Cait Poynor Lamberton (University of Pittsburgh) and Kristin Diehl (University of Southern California).

Beliefs about causes of obesity may impact weight, eating behavior

Whether a person believes obesity is caused by overeating or by a lack of exercise predicts his or her actual body mass, according to new research published in Psychological Science, a journal of the Association for Psychological Science.

Study shows how the Nanog protein promotes growth of head and neck cancer

COLUMBUS, Ohio-– A study led by researchers at The Ohio State University Comprehensive Cancer Center-– Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC–James) has identified a biochemical pathway in cancer stem cells that is essential for promoting head and neck cancer.

Why is it easier to lose 2-4 pounds rather than 3 pounds?

Consumers are more likely to pursue goals when they are ambitious yet flexible, according to a new study in the Journal of Consumer Research.

Free perks and upgrades: Could they actually embarrass consumers?

Consumers may not enjoy receiving free perks or upgrades in public, according to a new study in the Journal of Consumer Research.

"Preferential treatment is often conferred in public settings. When preferential treatment is unearned rather than earned, the presence of other consumers who do not receive the same treatment can diminish satisfaction for the consumer receiving preferential treatment," write authors Lan Jiang (University of Oregon), JoAndrea Hoegg, and Darren W. Dahl (both University of British Columbia).

The geometry of persuasion: How do seating layouts influence consumers?

Consumers seated in circular arrangements feel a greater need to belong than those seated in angular layouts, according to a new study in the Journal of Consumer Research.

"The geometric shape of a seating arrangement can impact consumers by priming one of two fundamental needs: a need to belong or a need to be unique. Consumers will be most favorable toward persuasion material (advertising) that is consistent with the primed need," write authors Rui (Juliet) Zhu (University of British Columbia) and Jennifer J. Argo (University of Alberta).

Why do appetizers matter more when you're dining out with friends?

First impressions of experiences have a greater impact when consumers share the experience with others, according to a new study in the Journal of Consumer Research.

"When consumers consume an experience alone, the end of the experience has a greater effect on their overall evaluations. On the other hand, when consumers consume an experience with others, the beginning has a greater influence on how they judge the entire experience," write authors Rajesh Bhargave (University of Texas, San Antonio) and Nicole Votolato Montgomery (University of Virginia).
