Illicit drug use may affect sexual function in men
2015-07-06
(Press-News.org) In a study of 1159 males who illicitly used amphetamines, half of participants said drug use had no impact on their sexual functions, while the other half reported impacts such as reduced erectile rigidity and sexual satisfaction, enhanced orgasmic intensity, and delayed ejaculation.
"Compared with 211 matched controls, amphetamine users were twice as likely to experience erectile dysfunction," said Dr. Bang-Ping Jiann, senior author of The Journal of Sexual Medicine study.
Amphetamines are a group of drugs that stimulate the central nervous system and contain ingredients such as amphetamine, methamphetamine, methylphenidate, and 3,4-methylenedioxymethamphetamine ("Ecstasy").

Researchers have long had reason to hope that blocking the flow of calcium into the mitochondria of heart and brain cells could be one way to prevent damage caused by heart attacks and strokes. But in a study of mice engineered to lack a key calcium channel in their heart cells, Johns Hopkins scientists appear to have cast a shadow of doubt on that theory. A report on their study is published online this week in Proceedings of the National Academy of Sciences.
"We confirmed that this calcium channel is important for heart function," says senior investigator Mark Anderson, ...

July 6, 2015 CHAPEL HILL, NC - Insulin resistance affects tens of millions of Americans and is a big risk factor for heart disease. Yet, some people with the condition never develop heart disease, while some experience moderate coronary blockages. Others, though, get severe atherosclerosis - multiple blockages and deterioration of coronary arteries characterized by thick, hard, plaque-ridden arterial walls. Researchers at the UNC School of Medicine created a first-of-its-kind animal model to pinpoint two biomarkers that are elevated in the most severe form of coronary disease.

Researchers have found several key differences among people who receive hospice care--which maintains or improves the quality of life for someone whose condition is unlikely to be cured--in assisted-living facilities (ALFs) compared with people who receive hospice care at home.
People receiving hospice care in ALFs were more likely to be older and female than people who received hospice care at home. Also, people living in ALFs enrolled in hospice care much earlier than patients living in home settings. This allowed them to receive more help from the hospice team before ...

Lyme disease is currently estimated to affect 300,000 people in the U.S. every year, and blacklegged ticks, the disease's main vector, have recently flourished in areas previously thought to be devoid of this arachnid.
A new study finds that the newly detected tick populations likely arose mainly from southern populations that migrated to nearby northern locations.
"The fine temporal and spatial scale of the samples analyzed allowed for precise estimates of the rate, timing, and direction of individual migratory events," said Dr. Camilo Khatchikian, lead author of the ...

DURHAM, N.C. -- Looking around at a 20th high school reunion, you might notice something puzzling about your classmates. Although they were all born within months of each other, these 38-year-olds appear to be aging at different rates.
Indeed they are, say the leaders of a large long-term human health study in New Zealand that has sought clues to the aging process in young adults.
In a paper appearing the week of July 6 in the Proceedings of the National Academy of Sciences, the team from the U.S., UK, Israel and New Zealand introduces a panel of 18 biological measures ...

Madison, Wis. -- In rhesus monkey families - just as in their human cousins - anxious parents are more likely to have anxious offspring.
And a new study in an extended family of monkeys provides important insights into how the risk of developing anxiety and depression is passed from parents to children.
The study from the Department of Psychiatry and the Health Emotions Research Institute at the University of Wisconsin-Madison shows how an over-active brain circuit involving three brain areas inherited from generation to generation may set the stage for developing ...

Across the entire world, women can expect to live longer than men. But why does this occur, and was this always the case?
According to a new study led by University of Southern California Leonard Davis School of Gerontology researchers, significant differences in life expectancies between the sexes first emerged as recently as the turn of the 20th century. As infectious disease prevention, improved diets and other positive health behaviors were adopted by people born during the 1800s and early 1900s, death rates plummeted, but women began reaping the longevity benefits ...

PITTSBURGH, July 6, 2015 - University of Pittsburgh Cancer Institute (UPCI) scientists recently led a panel of experts in revising national guidelines for thyroid cancer testing to reflect newly available tests that better incorporate personalized medicine into diagnosing the condition.
Their clinical explanation for when to use and how to interpret thyroid cancer tests is published in the July issue of the scientific journal Thyroid. The American Thyroid Association is revising its 2015 Guidelines for Thyroid Nodule and Thyroid Cancer Management to direct doctors to ...

Researchers have provided a new roadmap for tackling future agricultural production issues by using solutions that involve crassulacean acid metabolism (CAM), a specialized type of photosynthesis that enhances the efficiency by which plants use water.
Plants that use CAM, which include cacti and agave, are typically found in dry environments. Increasing agricultural production to accommodate society's growing population might be achieved by developing CAM crops as new sources for food, feed, fiber, and bioenergy or by engineering non-CAM crops to use CAM strategies to ...
