Caffeine counters cocaine's effects on women's estrus cycles
2014-11-20
(Press-News.org) New Rochelle, NY, November 20, 2014-Women are more sensitive to the effects of cocaine and more susceptible to cocaine abuse than men. Cocaine's ability to disrupt a woman's estrus cycle may explain the sex differences in cocaine addiction, and new evidence that caffeine may be neuroprotective and able to block cocaine's direct effects on the estrus cycle reveals novel treatment possibilities, according to an article published in Journal of Caffeine Research: The International Multidisciplinary Journal of Caffeine Science, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Caffeine Research website at http://online.liebertpub.com/doi/full/10.1089/jcr.2014.0015 until December 20, 2014.
In the article "Cocaine Shifts the Estrus Cycle Out of Phase and Caffeine Restores It", Patricia Broderick, PhD and Lauren Malave, City College of New York, City University of New York Graduate Center, City University of New York, and NYU Langone Medical Center, New York, NY, show that cocaine shifts the estrus cycle, thereby changing a woman's estrogen levels. Caffeine can block these changes, suggesting that antagonists of the adenosine system may have a role in treating cocaine addiction.
"This is cutting-edge work that has never been shown before. It is critical knowledge relevant to women's reproductive health," says Patricia A. Broderick, PhD, Editor-in-Chief of Journal of Caffeine Research and Medical Professor in Physiology, Pharmacology & Neuroscience, The Sophie Davis School of Biomedical Education, The City College of New York, The City University of New York, and Adjunct Professor in Neurology, New York University Langone Medical Center and Comprehensive Epilepsy Center.

Birds that are related, such as Darwin's finches, but that vary in beak size and behavior specially evolved to their habitat are examples of a process called speciation. It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent study shows that speciation occurred much later than these dramatic geographical changes. Researchers from LSU's Museum of Natural Science have found that time and a species' ability to move play greater parts ...

The higher your level of education, the greater your earnings and your sense of "personal mastery" or being in control of your fate, University of Toronto researchers say. But wait: there's a downside.
Professor Scott Schieman, Canada Research Chair in the Social Contexts of Health, and PhD student Atsushi Narisada investigated the adverse effects associated with attaining a high degree of mastery. Using the Canadian Work, Stress, and Health Study (CANWSH), a national sample of Canadian workers, the researchers measured proficiency, or mastery, by asking study participants ...

Thanks to the NASA/ESA Hubble Space Telescope, some of the most mysterious cosmic residents have just become even more puzzling. New observations of globular clusters in a small galaxy show they are very similar to those found in the Milky Way, and so must have formed in a similar way. One of the leading theories on how these clusters form predicts that globular clusters should only be found nestled in among large quantities of old stars. But these old stars, though rife in the Milky Way, are not present in this small galaxy, and so, the mystery deepens.
Globular clusters ...

Modern hand dryers are much worse than paper towels when it comes to spreading germs, according to new University of Leeds research.
Scientists from the University of Leeds have found that high-powered 'jet-air' and warm air hand dryers can spread bacteria in public toilets. Airborne germ counts were 27 times higher around jet air dryers in comparison with the air around paper towel dispensers.
The study shows that both jet and warm air hand dryers spread bacteria into the air and onto users and those nearby.
The research team, led by Professor Mark Wilcox of the ...

Almost one third of male adolescents inaccurately perceive their weight. This can influence their eating habits and, consequently, their health, according to a study led by the UAB and conducted with 600 teenage boys from Barcelona and surrounding areas. Up to 25% of the boys reported trying to lose or control their weight in the past year.
The research, conducted in collaboration with the Mental Health Unit of the Parc Taulí Health Corporation (CSPT), analysed the effects weight perception had on the boys' behaviour when trying to lose or maintain their weight. ...

WASHINGTON - U.S. Naval Research Laboratory (NRL) scientists, in collaboration with researchers from the University of Manchester, U.K.; Imperial College, London; University of California San Diego; and the National Institute of Material Science (NIMS), Japan, have demonstrated that confined surface phonon polaritons within hexagonal boron nitride (hBN) exhibit unique metamaterial properties that enable novel nanoscale optical devices for use in optical communications, super-resolution imaging and improved infrared cameras and detectors.
Metamaterials are artificial composites ...

Las Médulas in León is considered to be the largest opencast goldmine of the Roman Empire, but the search for this metal extended many kilometres further south-east to the Erica river valley. Thanks to a Light Detection and Ranging (LiDAR) laser system attached to an aircraft, the ancient mining works of the area and the complex hydraulics system used by the Romans in the 1st century BC to extract gold (including channels, reservoirs and a double river diversion) have been discovered.
"The volume of earth exploited is much greater than previously thought and ...

Researchers from North Carolina State University have developed a technique that allows ultrasound to penetrate bone or metal, using customized structures that offset the distortion usually caused by these so-called "aberrating layers."
"We've designed complementary metamaterials that will make it easier for medical professionals to use ultrasound for diagnostic or therapeutic applications, such as monitoring blood flow in the brain or to treat brain tumors," says Tarry Chen Shen, a Ph.D. student at NC State and lead author of a paper on the work. "This has been difficult ...

A new database developed by the University of Cantabria (Spain) provides data on sea level variation due to atmospheric changes in the south of Europe between 1948 and 2009. Over the last two decades sea levels have increased in the Mediterranean basin.
"The meteorological sea level or meteorological tide component is the variation of the sea level as a result of atmospheric changes or more specifically, changes in the atmospheric pressure and the wind at the sea surface," Alba Cid explains to SINC, Alba being the lead author of the study published in the journal 'Climate ...
