CINCINNATI -- Results of an analysis from the University of Cincinnati (UC) College of Medicine show that additional therapy, or adjuvant therapy, delivered after surgical removal of a rare type of gastrointestinal tumor does not increase survival rates for patients.
These findings, being presented Saturday, March 24, 2018, at the Society of Surgical Oncology Annual Cancer Symposium in Chicago, provide insight on treatment plans for patients with these types of tumors possibly eliminating the need for prescribed adjuvant therapy, preserving quality of life and saving money.
A study undertaken by British American Tobacco has shown that teeth exposed to cigarette smoke over a period of 2 weeks became very discoloured very quickly, whereas teeth exposed to e-cigarette vapour or vapour from glo, a tobacco-heated product, did not (Figure 1). After 2 weeks of almost continuous exposure, these teeth were almost indistinguishable from teeth that were not exposed to anything at all.
Alexandria, VA, USA - At the 47th Annual Meeting of the American Association for Dental Research (AADR), held in conjunction with the 42nd Annual Meeting of the Canadian Association for Dental Research (CADR), Veerasathpurush Allareddy, University of Iowa, College of Dentistry & Dental Clinics, Iowa City, presented a poster titled "Opioid Abuse/Dependence in Those Hospitalized Due to Periapical Abscess." The AADR/CADR Annual Meeting is in Fort Lauderdale, Fla., USA from March 21-24, 2018.
Researchers at Griffith University working with Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) have unveiled a stunningly accurate technique for scientific measurements which uses a single atom as the sensor, with sensitivity down to 100 zeptoNewtons.
Using highly miniaturised segmented-style Fresnel lenses - the same design used in lighthouses for more than a century - which enable exceptionally high-quality images of a single atom, the scientists have been able to detect position displacements with nanometre precision in three dimensions.
Alexandria, VA, USA - At the 47th Annual Meeting of the American Association for Dental Research (AADR), held in conjunction with the 42nd Annual Meeting of the Canadian Association for Dental Research (CADR), Prescott McWilliams, United States Air Force, San Antonio, Texas and the Uniformed Services University of the Health Sciences (USU), Postgraduate Dental College (PDC), presented a poster titled "Effect of Deployment on Use of E-Cigarettes in U.S. Military." The AADR/CADR Annual Meeting is in Fort Lauderdale, Fla., USA from March 21-24, 2018.
A new Drexel University study found that 30 percent of mayors don't believe civic policies can reduce health disparities in their cities, and it appears that individual political ideology is strongly related to those beliefs.
Alexandria, VA, USA - At the 47th Annual Meeting of the American Association for Dental Research (AADR), held in conjunction with the 42nd Annual Meeting of the Canadian Association for Dental Research (CADR), Hyun Hong, The Dental College of Georgia at Augusta University, presented a poster titled "Investigating the Enigmatic Link Between Periodontal Inflammation and Retinal Degeneration." The AADR/CADR Annual Meeting is in Fort Lauderdale, Fla., USA from March 21-24, 2018.
Insights from past failures can help boost performance on a new task -- and a new study is the first to explain why. US researchers report that writing critically about past setbacks leads to lower levels of the "stress" hormone, cortisol, and more careful choices when faced with a new stressful task, resulting in improved performance.
WASHINGTON, DC AND SILVER SPRING, MD (March 23, 2018)--Despite the high prevalence of obesity among U.S. adults, provision of recommended treatments for obesity remains low. Providers cite lack of time, lack of reimbursement, and lack of knowledge as major barriers to treating patients with obesity. A new study published in Obesity assessed health care professionals' (HCPs') knowledge of evidence-based guidelines for nonsurgical treatment of obesity.
Tokyo, Japan - Researchers from Tokyo Metropolitan University studied the neural response of Japanese junior high school students learning English as a second language, while listening to English sentences. More proficient boys showed more activation in parts of the brain associated with grammatical rules (syntax); girls used a wider range of language information, including speech sounds (phonology) and meaning of words and sentences (semantics). These discoveries may help optimize how boys and girls are taught English.
Alexandria, VA, USA - At the 47th Annual Meeting of the American Association for Dental Research (AADR), held in conjunction with the 42nd Annual Meeting of the Canadian Association for Dental Research (CADR), Abby Siefker, The Ohio State University, Columbus, presented an oral session titled "The Subgingival Virome in Periodontal Health and Disease." The AADR/CADR Annual Meeting is in Fort Lauderdale, Fla., USA from March 21-24, 2018.
HOUSTON - (March 22, 2018) - It's easy and economical to make shiny pellets of graphite from functionalized graphene, according to scientists at Rice University.
A report in Carbon shows how chemically altered graphene powder can be pressed into a lightweight, semiporous solid that retains many of the strong and conductive qualities of graphite, the form of carbon found in pencils, lubricants and many other products that normally requires high-temperature processing to make.
Scientists have recently learned how to use light to control specific groups of neurons to better understand the operation of the brain, a development that has transformed areas of neuroscience.
Researchers at Princeton University have now applied a similar method to controlling the metabolism, or basic chemical process, of a living cell. In a series of experiments, they used light to control genetically-modified yeast and increase its output of commercially valuable chemicals. The results offer scientists a powerful new tool to probe and understand the inner working of cells.
NEW YORK (March 22, 2018) -- Logging activities in biodiverse forests can have a huge negative impact on wildlife, particularly large species such as big cats, but a new study proves that the Western Hemisphere's largest cat species--the jaguar (Panthera onca)--can do well in logging concessions that are properly managed, according to conservationists from the San Diego Zoo Global and the Bronx Zoo-based WCS (Wildlife Conservation Society).
Neurology researchers investigating a rare but devastating neurological regression in infants have discovered the cause: gene mutations that severely disrupt crucial functions in mitochondria, the energy-producing structures within cells. The specific disease mechanism, in which mutations disrupt a critical mitochondrial enzyme, has not previously been implicated in a human disease.
