(Press-News.org) New Rochelle, NY, April 7, 2014—Elevated pressure in the eye is the most common risk factor for glaucoma, an optic neuropathy that can cause blindness and affects more than 67 million people worldwide. Elevated eye pressure in glaucoma develops due to abnormal functioning of the trabecular meshwork (TM) causing intraocular fluid to back up. Next-generation glaucoma drugs will target the finely tuned mechanisms of the TM that maintain normal intraocular pressure, as described in an article in Journal of Ocular Pharmacology and Therapeutics, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article, one of 25 articles in a special double issue of the Journal, is available free on the Journal of Ocular Pharmacology and Therapeutics website.
The article "Intraocular Pressure Homeostasis: Maintaining Balance in a High-Pressure Environment," by Ted Acott and coauthors, Oregon Health & Science University, Portland, OR, describes the efficient mechanisms at work in the eye to keep intraocular pressure within an acceptable range for 92-98% of the population. Understanding these mechanisms will enable the development of drug interventions to treat the unfortunate 2-8% of people that are at risk of developing elevated eye pressure and glaucoma.
"The TM, a unique multilayered tissue that controls intraocular pressure, and its surrounding structures represent viable targets for the development of novel glaucoma therapies," write Editor-in-Chief W. Daniel Stamer, PhD, Duke University (Durham, NC) and Guest Editor John R. Samples, MD, Professor, Rocky Vista University and Director, Western Glaucoma Foundation, Portland, OR, in the Editorial "The Trabecular Meshwork Special Issue, Inspired by the TM Study Club."
The special double issue provides a comprehensive look at the TM and next-generation glaucoma therapies in development through a collection of editorials, original research articles, and reviews. Included is the review article "The Role of TGF-ß2 and Bone Morphogenetic Proteins in the Trabecular Meshwork and Glaucoma," in which Robert Wordinger, Tasneem Sharma, and Abbot Clark, University of North Texas Health Science Center, Fort Worth, describe the TGF-ß superfamily of growth factors and their role in primary open-angle glaucoma (POAG), the second leading cause of blindness worldwide.
Also of note, Nelson Winkler, Mayo Clinic College of Medicine, and Michael Fautsch, Mayo Clinic, Rochester, MN, explore the current understanding of how prostaglandin analogues, first-line treatments for glaucoma, work to reduce elevated intraocular pressure, in the review article "Effects of Prostaglandin Analogues on Aqueous Humor Outflow Pathways."

Experience helps restaurant managers stick with local foods
2014-04-07
Restaurant chefs and food purchasing managers who have bought local foods in the past are more likely to continue adding them to menus and store shelves, according to a team of researchers.
"Past experiences will have an impact on buying local foods," said Amit Sharma, associate professor of hospitality management, Penn State. "Restaurant managers who buy local foods currently are significantly more likely to keep purchasing locally."
In a study of the cost and benefits of purchasing local foods in restaurants, managers and chefs indicated that certain actions of local ...
The social circuits that track how we like people and ideas
2014-04-07
Boston – April 7, 2014 - Whether at the office, dorm, PTA meeting, or any other social setting, we all know intuitively who the popular people are – who is most liked – even if we can't always put our finger on why. That information is often critical to professional or social success as you navigate your social networks. Yet until now, scientists have not understood how our brains recognize these popular people. In new work, researchers say that we track people's popularity largely through the brain region involved in anticipating rewards.
"Being able to track other ...
Slowdown of global warming fleeting
2014-04-07
The recent slowdown in the warming rate of the Northern Hemisphere may be a result of internal variability of the Atlantic Multidecadal Oscillation -- a natural phenomenon related to sea surface temperatures, according to Penn State researchers.
"Some researchers have in the past attributed a portion of Northern Hemispheric warming to a warm phase of the AMO," said Michael E. Mann, Distinguished Professor of Meteorology. "The true AMO signal, instead, appears likely to have been in a cooling phase in recent decades, offsetting some of the anthropogenic warming temporarily." ...
U Of T researchers offer hope for children with previously incurable brain cancer
2014-04-07
Researchers from the University of Toronto's Department of Laboratory Medicine and Pathobiology (LMP) have defined potential treatment targets for a previously incurable form of pediatric brain cancer called Diffuse Intrinsic Pontine Glioma (DIPG).
In groundbreaking research published in Nature Genetics, Dr. Cynthia Hawkins, a professor at LMP and Neuropathologist and Scientist at The Hospital for Sick Children, along with PhD candidates Pawel Buczkowicz and Patricia Rakopoulos, identified three subgroups of DIPG, each having distinct molecular features.
"In the past, ...
New research shows huge disparities between the decisions made by coroners
2014-04-07
GOVERNMENT plans to overhaul the centuries-old coroner system in England and Wales have been bolstered by the findings of a leading police officer who has become a PhD researcher at the University of Huddersfield. Detailed analysis by ex-Detective Chief Superintendent Max Mclean has shown that there are huge disparities between the decisions made by coroners in differing districts, with the troubling discovery that the deaths of women are considerably less likely to be investigated at an inquest.
The result is a "postcode lottery", claims Mr Mclean, who calls for a fully-fledged ...
Disruption of VISTA plays an important role in regulating immune response
2014-04-07
Researchers at the Geisel School of Medicine at Dartmouth have found that the body's immune system response was enhanced when they disrupted VISTA, a protein that prevents the immune system from overreacting. Understanding how checkpoint regulators like VISTA function is important to cancer researchers, who hope to use the immune system to attack tumors. The study, "VISTA deficiency synergizes with a nonredundant immune checkpoint pathway and leads to enhanced immune activation," will be presented on April 7, 2014 at the American Association for Cancer Research Annual Meeting ...
Henry Ford Hospital cited: World's first surgical innovators for patient safety standards
2014-04-07
DETROIT – An innovative kidney transplant technique developed by Henry Ford Hospital is credited as the first in the world to use a new set of patient safety standards coordinated by the University of Oxford in England.
The standards are being assembled and offered as a framework for developing, performing and reporting surgical innovations that, unlike new medical treatments, are not under strict regulations and control.
One historic example cited by the Oxford group was the introduction of tracheostomy as a surgical method of treating an obstruction in the trachea. ...
Tissue testing during breast cancer lumpectomies
2014-04-07
ROCHESTER, Minn. — Unique laboratory testing during breast cancer lumpectomies to make sure surgeons remove all cancerous tissue spares patients the need for a repeat lumpectomy in roughly 96 percent of cases at Mayo Clinic in Rochester, a success rate much higher than the rate nationally, a Mayo study shows. During the years reviewed, 13.2 percent of breast cancer lumpectomy patients nationally had to return to the operating room within a month of their initial surgery, compared to 3.6 percent at Mayo in Rochester, which uses a technique called frozen section analysis ...
