Mechanism Of Immunity Discovered
Date: Jun-21-2013Scientists at the University of Calgary's Faculty of Medicine have discovered a mechanism that is used to protect the body from harmful bacteria. Platelets, a component of blood typically associated with clotting, were discovered to actively search for specific bacteria, and upon detection, seal it off from the rest of the body. The findings, which were published in Nature Immunology this week, provide the science community with a greater understanding of immunity...
New Tool To Measure Sugar Consumption
Date: Jun-21-2013Scientists at the University of Alaska Fairbanks identified a new tool that can dramatically improve the notoriously inaccurate surveys of what and how much an individual eats and drinks. Their research is published in the June 2013 issue of the Journal of Nutrition. Conventional wisdom says that consumption of sugar-sweetened beverages such as soda and fruit juice is a significant contributor to obesity and chronic disease risk, but the science surrounding this issue is inconclusive...
Study Suggests New Approach To Fight Lung Cancer
Date: Jun-21-2013Recent research has shown that cancer cells have a much different - and more complex - metabolism than normal cells. Now, scientists at The University of Texas at Dallas have found that exploiting these differences might provide a new strategy to combat lung cancer. In an article published online in the journal PLOS ONE, UT Dallas researchers compared the metabolic characteristics of non-small-cell lung cancer cells with normal lung cells taken from the same patient. They found that the cancer cells consumed substantially more oxygen than normal cells, about two and a half times as much...
Signal Tells MCM7 To Launch DNA Replication; Pathway Reduces Breast Cancer Patient Survival
Date: Jun-21-2013Researchers have discovered and mapped the signaling network between two previously unconnected proteins, exposing a link that, if broken, could cut off cancer cell growth at its starting point. A team led by scientists at The University of Texas MD Anderson Cancer Center reported the tie between epidermal growth factor receptor (EGFR), a well-known cancer drug target, and MCM7, a protein vital to the first step in DNA replication, in the June issue of Cancer Cell...
How Doctors And Their Patients Communicate May Be The Key To Stopping HIV Patient 'No Shows'
Date: Jun-21-2013People with HIV are more likely to keep their scheduled medical appointments - and their disease under control - if they feel their physician listens, explains things clearly and knows them as a person, not just a "case," new Johns Hopkins research suggests. "If people feel their doctor really knows them and listens to them, they feel that doctor has their best interests at heart and may be more likely to follow medical advice," says study leader Tabor E. Flickinger, M.D., M.P.H., a fellow in the Division of General Internal Medicine at the Johns Hopkins University School of Medicine...
Anti-Cholesterol Formula Patented
Date: Jun-21-2013Senior Brandeis research scientist Daniel Perlman '68 has discovered a way to make phytosterol molecules from plants dispersible in beverages and foods that are consumed by humans, potentially opening the way to dramatic reductions in human cholesterol levels. A U.S. patent (number 8,460,738) on the new process and composition was issued on June 11. Phytosterols in plants and cholesterol molecules in animals are highly similar and when both are dispersed together they are attracted to one another...
New Simulations Help Scientists Understand How And Why Viruses Spread
Date: Jun-21-2013Computer modeling technique goes viral at Brandeis It's not a hacker lab. At Brandeis University, sophisticated computational models and advances in graphical processing units are helping scientists understand the complex interplay between genomic data, virus structure and the formation of the virus' outer "shell" - critical for replication...
Medical Students' Perspectives On Dementia Altered By Storytelling Program
Date: Jun-21-2013Treating patients with dementia can be viewed as a difficult task for doctors, but Penn State College of Medicine researchers say that storytelling may be one way to improve medical students' perceptions of people affected by the condition. Participation in a creative storytelling program called TimeSlips creates a substantial improvement in student attitudes. Daniel George, assistant professor of humanities, tested the effects of the TimeSlips program in an elective course he teaches at the college...
Pilot Study Has Promising Results For Age-Related Macular Degeneration
Date: Jun-21-2013There is no cure for age-related macular degeneration, an eye disease that is the leading cause of vision loss and blindness in older Americans. Last year, the National Institutes of Health reported that two drugs injected into the eyes, Avastin and Lucentis, eased symptoms for sufferers, especially those in the advanced, "wet" stage of the disease, when blood vessels in the eye become swollen and leak fluids in the eye. Yet for some AMD patients, the two drugs either don't work for long or fail to work at all. It's a dead end for treatment, or so it seemed...
A Psychosocial Research Perspective On Psychopathy And Criminal Behaviour
Date: Jun-21-2013This paper aims to provide a critical review of the psychopathy literature, with a particular focus on recent research examining the relationship between psychopathy and various forms of criminal behaviour. The authors provide an overview of the studies conducted to date. To identify relevant publications for inclusion in this review, literature searches were completed using Web of Science, Scopus, PsychINFO, and PubMed. Substantial empirical research exists to suggest that psychopathy is a robust predictor of criminal behaviour and recidivism...
