URBANA, Ill. – While researching methods to increase the already well-recognized anti-cancer properties of broccoli, researchers at the University of Illinois also found a way to prolong the vegetable's shelf life. And, according to the recently published study, the method is a natural and inexpensive way to produce broccoli that has even more health benefits and won't spoil so quickly on your refrigerator shelf. Jack Juvik, a U of I crop sciences researcher, explained that the combined application of two compounds, both are natural products extracted from plants, increased ...

URBANA, Ill. – Just as with people, feline obesity is most often linked to excessive food intake or not enough physical activity. Attempts to cut back on calories alone often result in failed weight loss or weight regain in both people and their pets. So how do you encourage your cat to get more exercise? Researchers from the University of Illinois interested in finding a method to maintain healthy body weight in cats, looked at a previously suggested claim that increased meal frequency could help to increase overall physical activity. The idea is to feed cats the ...

Philadelphia, Pa. (February 20, 2014) - Abnormal color vision increases significantly with aging—affecting one-half or more of people in the oldest age groups, reports a study in Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. While few people younger than 70 have problems with color vision, the rate increases rapidly through later decades of life, according to the new research by Marilyn E. Schneck, PhD, and colleagues of The Smith-Kettlewell ...

Plant growth is orchestrated by a spectrum of signals from hormones within a plant. A major group of plant hormones called cytokinins originate in the roots of plants, and their journey to growth areas on the stem and in leaves stimulates plant development. Though these phytohormones have been identified in the past, the molecular mechanism responsible for their transportation within plants was previously poorly understood. Now, a new study from a research team led by biochemist Chang-Jun Liu at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory identifies ...

The next time you want to turn down the emotional intensity before making an important decision, you may want to dim the lights first. A new study from the University of Toronto Scarborough shows that human emotion, whether positive or negative, is felt more intensely under bright light. Alison Jing Xu, assistant professor of management at UTSC and the Rotman School of Management, along with Aparna Labroo of Northwestern University, conducted a series of studies to examine the unusual paradox of lighting and human emotion. "Other evidence shows that on sunny days people ...

People with late-stage cancer at the back of the mouth or throat that recurs after chemotherapy and radiation treatment are twice as likely to be alive two years later if their cancer is caused by the human papillomavirus (HPV), new research led by a Johns Hopkins scientist suggests. Previous studies have found that people with so-called HPV-positive oropharyngeal cancers are more likely to survive than those whose cancers are related to smoking or whose origins are unknown. The new study, scheduled to be presented Feb. 20 at the 2014 Multidisciplinary Head and Neck ...

Scottsdale, Ariz., February 20, 2014—Patients who received daily humidification of the mouth and throat region beginning from day one of radiation therapy treatment spent nearly 50 percent fewer days in the hospital to manage their side effects, according to research presented today at the 2014 Multidisciplinary Head and Neck Cancer Symposium. The study was conducted by the Trans Tasman Radiation Oncology Group and evaluated 210 head and neck cancer patients in New Zealand and Australia from June 2007 through June 2011. Patients in this Phase III trial were randomized ...

Scottsdale, Ariz., February 20, 2014—A retrospective analysis of oropharyngeal patients with recurrence of disease after primary therapy in the Radiation Therapy Oncology Group (RTOG) studies 0129 or 0522 found that HPV-positive patients had a higher overall survival (OS) rate than HPV-negative patients (at two years post-treatment, 54.6 percent vs. 27.6 percent, respectively), according to research presented today at the 2014 Multidisciplinary Head and Neck Cancer Symposium. The analysis included 181 patients with stage III-IV oropharyngeal squamous cell carcinoma (OPSCC) ...

Scottsdale, Ariz., February 20, 2014—Patients with HPV-positive squamous cell carcinoma of the oropharynx (SCCOP) had a longer time to development of distant metastasis (DM) after initial treatment, and had more metastatic sites in more atypical locations compared to HPV-negative patients, according to research presented today at the 2014 Multidisciplinary Head and Neck Cancer Symposium. Culled from records of an IRB-approved registry, the study reviewed 285 patients with stage III-IV SCCOP (originally thought to be a smoking-related head and neck cancer) treated with ...

Scottsdale, Ariz., February 20, 2014—Avoiding the contralateral submandibular gland during radiation therapy is feasible and safe with advanced stage, node positive head and neck cancers and base of tongue lesions, according to research presented today at the 2014 Multidisciplinary Head and Neck Cancer Symposium. Researchers conducted a retrospective analysis of 71 patients from two facilities—the University of Colorado Cancer Center and the Memorial Sloan-Kettering Cancer Center. The median patient age was 55, and about 50 percent of the patients were current or former ...

Scottsdale, Ariz., February 20, 2014—Oropharyngeal cancer patients treated with combined chemotherapy and radiation therapy reported a decrease in their voice and speech quality (VSQ) for up to one year after the completion of treatment, according to research presented today at the 2014 Multidisciplinary Head and Neck Cancer Symposium. The study further shows that limiting the dose of radiation to the glottic larynx (GL) to less than 20 Gy resulted in a decrease in post-treatment VSQ problems, and that patient-reported VSQ indicated more adverse effects from treatment compared ...

Scottsdale, Ariz., February 20, 2014—For head and neck cancer patients undergoing radiation therapy, a reduction in the amount of radiation treatment volume to the submandibular (level IB) lymph nodes resulted in better patient-reported salivary function, according to research presented today at the 2014 Multidisciplinary Head and Neck Cancer Symposium. The study results also found significant reductions in radiation dose to the salivary organs, and good local regional control. Researchers evaluated 125 patients with node-positive oropharyngeal cancer who received chemoradiation ...

Scottsdale, Ariz., February 20, 2014—Limiting radiation therapy to lymph nodes on one side of the neck for advanced tonsil cancer resulted in good local regional control and no cancer recurrence on the untreated side, according to research presented today at the 2014 Multidisciplinary Head and Neck Cancer Symposium. Additionally, the study results indicate that primary tumor location, rather than the amount of lymph node involvement on the tumor side of the neck, dictates the risk for disease in the opposite side of the neck. The study focused on 46 out of 153 total patients ...

Scottsdale, Ariz., February 20, 2014—Evaluating next-generation sequencing (NGS) data and associated clinical records of head and neck squamous cell carcinoma (HNSCC) patients from several institutions, made available through The Cancer Genome Atlas (TCGA), showed that combining Mutant-Allele Tumor Heterogeneity (MATH) as a biomarker with the patient's HPV status provides an effective indicator of improved patient outcome, according to research presented today at the 2014 Multidisciplinary Head and Neck Cancer Symposium. The TCGA data available for HNSCC patients included ...

The increased demand for primary care services expected to result from the Affordable Care Act (ACA) may be felt strongly in rural areas. While studies have found that the quality of care delivered to rural patients is as good or better than that available in urban areas, the belief persists that top-quality primary care is only available in big cities. But a new study appearing in the National Rural Health Association's Journal of Rural Health finds few meaningful differences between rural and urban primary care physicians on key measures of professionalism, including ...

HUNTSVILLE, TX (2/20/14) -- Conflicts between work and family life were the most significant issues that affect work stress and job satisfaction among correctional officers, a new study by the Correctional Management Institute of Texas at Sam Houston State University found. In a study of 441 correctional officers from adult prisons in the South, the most significant work-home issues experienced by correctional officers were demands and tensions from work that impact their home life; an incompatibility between the officer's role at work and at home; and family circumstances ...

Speed dating, in which potential lovers size each other up in brief 10 minute encounters before moving on to the next person, can be an awkward and time-wasting affair. Finding the perfect research partnership is often just as tough. Speed dating-style techniques are increasingly used at academics conferences, but can be equally frustrating - with busy academics being pushed into too many pointless encounters. But now a group of scientists led by geneticist Rafael Carazo Salas have constructed a system that could revolutionise conference speed dating - by treating scientists ...

BOSTON (February 20, 2014)—An editorial in a February issue of American Family Physician proposes a simple way for physicians to communicate with patients about the best treatments for diabetes. The "lending a hand" illustration reprioritizes treatment goals, based on research on mortality reduction, to convey that glycemic control is no longer the primary intervention. In order of benefit, to improve length and quality of life, patients with type 2 diabetes benefit from these interventions, starting with smoking cessation: "Glycemic control is stuck in people's minds ...

New Rochelle, NY, February 20, 2014—Children exhibit a range of responses to traumatic events such as natural disasters, with some suffering acute traumatic reactions that resolve over time and others experiencing long-term symptoms of post-traumatic stress. Identifying factors that may help predict which youths are at greater risk of more serious disorders and which are likely to be more resilient following a traumatic event can help determine the care and services needed, according to an article in Journal of Child and Adolescent Psychopharmacology (JCAP), a peer-reviewed ...

During very strong El Niño events, sea level drops abruptly in the tropical western Pacific and tides remain below normal for up to a year in the South Pacific, especially around Samoa. The Samoans call the wet stench of coral die-offs arising from the low sea levels "taimasa" (pronounced [kai' ma'sa]). Studying the climate effects of this particular variation of El Niño and how it may change in the future is a team of scientists at the International Pacific Research Center, University of Hawai'i at Mānoa and at the University of New South Wales, Australia. Two El ...

Using a telescope installed at the driest place on earth - Ridge A in Antarctica – a UNSW-led team of researchers has identified a giant gas cloud which appears to be in an early stage of formation. Giant clouds of molecular gas – the most massive objects in our galaxy – are the birthplaces of stars. "This newly discovered gas cloud is shaped like a very long filament, about 200 light years in extent and ten light years across, with a mass about 50,000 times that of our sun," says team leader, Professor Michael Burton, an astronomer at UNSW Australia. "The evidence suggests ...

EAST LANSING, Mich. — From Ethiopia to Nicaragua, countries that go through civil war are much less likely to become democratic if the winning side gets help from rival nations, a Michigan State University political scientist argues. In a new study examining democratization after civil wars since World War II, Michael Colaresi found the majority of groups that eventually took power failed to establish democratic governments if those groups took money or weapons from a foreign enemy during the war. Receiving such aid can create mistrust among the nation's citizens and ...

Nowadays, humanity faces many challenges; the most serious are poverty, the growing demand for resources and the deterioration of the environment. In order to satisfy the growing demand for wood, forestry in many countries has to be intensified. The forests of the Russian Federation are the world's largest reserve of wood for different purposes. Intensification of forestry in Russia will result in increasing availability of wood for material and energy uses. A doctoral dissertation completed at the University of Eastern Finland analysed the potential of energy wood resources ...

This news release is available in German. Numerous German companies are operating globally these days: They develop products domestically, but production is done in other countries like China, Brazil or the Czech Republic. If maintenance or repair work is needed, the engineers who had designed the complex production plants frequently have to travel from Germany. A novel approach by computer scientists in the research group of professor Thorsten Herfet from the Chair of Telecommunications at Saarland University could provide a solution: a platform that brings together ...

Establishing and maintaining relationships online is becoming ever more important in the expanding global knowledge economy. But what happens to the relationship between business and consumer when a user "unfriends"? Writing in the International Journal of the Business Environment, Christopher Sibona and Steven Walczak of The Business School, at the University of Colorado Denver, USA, have found that there are many online and offline reasons why a person might "unfriend" another party. The team has examined these factors and offer insights into how virtual business relationships ...
