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.

About the Journal

Journal of Caffeine Research: The International Multidisciplinary Journal of Caffeine Science is a quarterly journal published in print and online. The Journal covers the effects of caffeine on a wide range of diseases and conditions, including mood disorders, neurological disorders, cognitive performance, cardiovascular disease, and sports performance. Journal of Caffeine Research explores all aspects of caffeine science including the biochemistry of caffeine; its actions on the human body; benefits, dangers, and contraindications; and caffeine addiction and withdrawal, across all stages of the human life span from prenatal exposure to end-of-life.

Wheat diseases caused by a host of viruses that might include wheat streak mosaic, triticum mosaic, soil-borne mosaic and barley yellow dwarf could cost producers 5 to 10 percent or more in yield reductions per crop, but a major advance in developing broad disease-resistant wheat is on the horizon.

John Fellers, molecular biologist for the U.S. Department of Agriculture's Agricultural Research Service, and Harold Trick, plant geneticist for Kansas State University, have led an effort to develop a patent-pending genetic engineering technology that builds resistance to certain viruses in the wheat plant itself. And although genetically engineered wheat is not an option in the market today, their research is building this resistance in non-genetically engineered wheat lines as well.

"(Wheat viruses) are a serious problem," Trick said. "Wheat streak mosaic virus is one of the most devastating viruses we have. It's prevalent this year. In addition to that, we have several other diseases, triticum mosaic virus and soil-borne mosaic virus, that are serious diseases."

Knowing how costly these diseases can be for producers, Fellers has worked on finding solutions for resistance throughout his career. As a doctoral student at the University of Kentucky, he used a technology in his research called pathogen-derived resistance, or RNA-mediated resistance -- a process that requires putting a piece of a virus into a plant to make it resistant to that particular virus. Most of the viruses that infect wheat are RNA viruses, he said.

"The plant has its own biological defense system," Fellers said. "We were just triggering that with this technology."

Now Fellers, with the help of Trick, his wheat transformation facility and K-State graduate students, have developed transgenic wheat lines that contain small pieces of wheat streak mosaic virus and triticum mosaic virus RNA.

"It's kind of like forming a hairpin of RNA," Fellers said. "What happens is the plant recognizes this RNA isn't right, so it clips a piece of it and chops it up, but then it keeps a copy for itself. Then we have a resistance element."

Fellers compared the process to the old days of viewing most wanted posters on the post office wall. The piece of foreign RNA from the virus, which is a parasite, is one of those most wanted posters. Because the virus is a parasite, it has to seize or hijack part of the plant system to make proteins that it needs to replicate.

When the virus comes into the plant, the plant holds up that poster from the post office wall, recognizes the virus, and doesn't allow the virus to replicate and go through its lifecycle.

New Rochelle, NY, November 17, 2014--In the future, as space exploration takes astronauts on longer missions and more female astronauts participate, "The Impact of Sex and Gender on Adaptation to Space" will become increasingly critical to astronaut safety and mission success, as explored in a special collection of articles published in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The articles are available Open Access on the Journal of Women's Health website at http://online.liebertpub.com/toc/jwh/23/11.

In the Executive Summary, Drs. Saralyn Mark, Graham Scott, Dorit Donoviel, Lauren Leveton, John Charles, and Bette Siegel and Ms. Erin Mahoney from National Aeronautics and Space Administration (NASA), National Space Biomedical Research Institute (NSBRI), and Valador, Inc. provide an overview of six individual articles in the November issue of the Journal derived from the findings of workgroups formed to report on the current research related to sex- and gender-based differences in how humans adapt to spaceflight. Each workgroup and article focuses on a specific type of adaptation: cardiovascular, immunological, sensorimotor, musculoskeletal, reproductive, and behavioral.

In her Commentary, Dr. Mark remarks that in addition to ongoing missions for the purpose of space exploration and research, "NASA has promoted the development of the commercial space sector for the transport of payloads and eventually humans." The impact of sex and gender should influence "the development of equipment, machine-human interfaces, and countermeasures including the use of personalized medicine and genomics or -'astro-omics.'"

"Understanding sex and gender differences in physiological and psychological adaptation to space is increasingly important as the number of female astronauts increases," says Susan G. Kornstein, MD, Editor-in-Chief of Journal of Women's Health, Executive Director of the Virginia Commonwealth University Institute for Women's Health, Richmond, VA, and President of the Academy of Women's Health.
