A recently published paper highlights that while the risk of post-traumatic stress disorder (PTSD) is more common in those with migraine than those without migraine irrespective of sex, the risk is greater in male migraineurs than female migraineurs. Study details are now available in Headache: The Journal of Head and Face Pain, published by Wiley-Blackwell on behalf of the American Headache Society.

New research raises the possibility that the critically short supply of livers for organ donation could be expanded by treating so-called "marginal" livers with a substance that protects them from damage after being connected to recipients' blood supplies. The report appears in ACS' journal Molecular Pharmaceutics.
With the curtain about to rise on a much-anticipated new era of "nanoagriculture" — using nanotechnology to boost the productivity of plants for food, fuel, and other uses —scientists are reporting a huge gap in knowledge about the effects of nanoparticles on corn, tomatoes, rice and other food crops. Their article appears in ACS' Journal of Agricultural and Food Chemistry.
Who would have thought that Gila monster saliva would be the inspiration for a blockbuster new drug for Type 2 diabetes? Or that medicines for chronic pain, heart attacks, high blood pressure and stroke would emerge from venom of the Magician's cone snail, the saw-scaled viper, the Brazilian lancehead snake and the Southeastern pygmy rattlesnake? These are just some of the sources contributing to the emergence of potential new drugs based on "peptides" that is the topic of the cover story in the current edition of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine.
Patients who undergo surgery are more likely to suffer surgical site infections (SSIs) if the operating theatre is noisy, according to research published in the July issue of BJS, the British Journal of Surgery.
Swiss researchers studied 35 patients who underwent planned, major abdominal surgery, exploring demographic parameters, the duration of the operation and sound levels in the theatre. Six of the patients (17 per cent) developed SSIs and the only variable was the noise level in the operating theatre, which was considerably higher in the infected patients.
"Even though the number of veterans in this study was small, the results were very impressive," Rosenthal said. "These young men were in extreme distress as a direct result of trauma suffered during combat, and the simple and effortless Transcendental Meditation technique literally transformed their lives."
A PhD student at the University of Leeds has developed a fast, accurate and inexpensive method of creating detailed vegetation community maps over very large areas, by coupling aerial photographs with data from maps.
Working in partnership with the Yorkshire Dales National Park Authority, Ute Bradter from Leeds' Faculty of Biological Sciences, has collated existing data (such as soil type, altitude, slope and aspect) and using a sophisticated statistical model, predicted the distribution of plant communities at a high resolution in the Yorkshire Dales, over 1600 km2.
ANN ARBOR, Mich.---University of Michigan physicists used the electric fields generated by intersecting laser beams to trap and manipulate thousands of microscopic plastic spheres, thereby creating 3-D arrays of optically induced crystals.
The technique could someday be used to analyze the structure of materials of biological interest, including bacteria, viruses and proteins, said U-M physicist Georg Raithel.
Asian non-small cell lung cancer (NSCLC) patients survive longer than Caucasians no matter how many drugs are given in a first-line setting, and the effect was apparent both before and after the introduction of targeted therapies in the early 2000s, according to research published in the June issue of the Journal of Thoracic Oncology.
CORVALLIS, Ore. – The Internet is empowering its users more than ever, but the same technology that allows people access to limitless information has also enabled some to combat scientific or medical authority with their personal experiences.
The surgical removal of the appendix and tonsils before the age of 20 was associated with an increased risk of premature heart attack in a large population study performed in Sweden.(1) Tonsillectomy increased the risk by 44% (hazard ratio 1.44) and appendectomy by 33% (HR 1.33). The risk increases were just statistically significant, and were even higher when the tonsils and appendix were both removed. However, there was no risk association evident when the operations were performed in people over the age of 20.
Philadelphia, PA, June 1, 2011 – Although gynecologic cancers account for only 10 percent of all new cancer cases in women, these cancers account for 20 percent of all female cancer survivors. Because long-term survival is now more common, it is increasingly important to detect recurrence. The Clinical Practice Committee of the Society of Gynecologic Oncology (SGO) has released a Clinical Document outlining their expert recommendations for cancer surveillance, published today in the American Journal of Obstetrics & Gynecology (AJOG).
TORONTO, June 1, 2011– Despite significant clinical advances in HIV care, an estimated 25 per cent of new HIV infections in Ontario from 2006 to 2008 were among women, according to a health study by researchers from the Institute for Clinical Evaluative Sciences (ICES) and St. Michael's Hospital. The researchers say 93 per cent of new infections among women are acquired through sexual transmission and seven per cent through injection drug use. About 60 per cent of newly infected women are immigrants.
Radiology benefit managers (RBMs) — which provide prior authorization for imaging services using proprietary algorithms to determine appropriateness — shift significant costs to physicians and have the potential to either increase or decrease societal costs, according to a study in the June issue of the Journal of the American College of Radiology (www.jacr.org).
Since the Industrial Revolution, over half of all the CO2 produced by burning fossil fuels has been absorbed by the ocean, making pH drop faster than any time in the last 650,000 years and resulting in ocean acidification. Recent studies have shown that this causes fish to lose their sense of smell, but a new study published today in Biology Letters shows that fish hearing is also compromised.
