Brain Aneurysm Treatment Used To Stop Irregular Heart Rhythms
Date: Mar-18-2013For the first time, a UCLA team has used a technique normally employed in treating brain aneurysms to treat severe, life-threatening irregular heart rhythms in two patients. This unique use of the method helped stop ventricular arrhythmias - which cause "electrical storms" - that originated in the septum, the thick muscle that separates the heart's two ventricles. This area is virtually impossible to reach with conventional treatment. The research was published recently in Heart Rhythm, the official journal of the Heart Rhythm Society, and is highlighted on the cover...
News From The Journal MBio®, Volume 4, Issue 1
Date: Mar-18-20131 Disarming One of the Deadliest Pathogens Francisella tularensis, the cause of tularemia and one of the deadliest respiratory pathogens in existence, is considered a potential biological weapon because it is readily aerosolized and exhibits a high degree of infectivity and lethality in humans. While a live attenuated vaccine strain has been developed, it remains unlicensed because scientists have been unable to understand the basis for its attenuated virulence...
Copper Detoxification Used As Crafty Defense Mechanism By The Fungus Cryptococcus neoformans
Date: Mar-18-2013A potentially lethal fungal infection appears to gain virulence by being able to anticipate and disarm a hostile immune attack in the lungs, according to findings by researchers at Duke Medicine. Defense mechanisms used by the fungus Cryptococcus neoformans enable it to lead to fatal meningitis, which is one of the opportunistic infections often associated with death in HIV/AIDS patients, organ transplant recipients, diabetics and other immunosuppressed patients. In describing the complex process of how C...
Enhanced Electronic Medical Record Aging Brain Care Software Unveiled
Date: Mar-18-2013Innovative medical records software developed by geriatricians and informaticians from the Regenstrief Institute and the Indiana University Center for Aging Research will provide more personalized health care for older adult patients, a population at significant risk for mental health decline and disorders...
Insights Into Human Cognitive Development Provided By Pig Brain Models
Date: Mar-18-2013A mutual curiosity about patterns of growth and development in pig brains has brought two University of Illinois research groups together. Animal scientists Rod Johnson and Ryan Dilger have developed a model of the pig brain that they plan to use to answer important questions about human brain development. "It is important to characterize the normal brain growth trajectory from the neonatal period to sexual maturity," said Johnson. "Until we know how the brain grows, we don't know what is going to change," added Dilger...
Teen Sexting: The Gender Gap And The Potential For Long-Term Harm
Date: Mar-18-2013Sexting: Involves sending sexually explicit messages and/or photographs, primarily between mobile phones using the SMS system was first reported in 2005. It is an obvious portmanteau of "sex" and "texting"; the word was added to the Merriam-Webster's Collegiate Dictionary in August 2012. 4% of mobile phone-owning teens claim to have sent sexually suggestive, nude or nearly nude images or videos of themselves to someone else via a mobile device while 15% claim to have received such material from someone they know...
Not Drinking Milk At College Age Increases Risk For Metabolic Syndrome
Date: Mar-18-2013College-age kids who don't consume at least three servings of dairy daily are three times more likely to develop metabolic syndrome than those who do, said a new University of Illinois study. "And only one in four young persons in the study was getting the recommended amount of dairy," said Margarita Teran-Garcia, a U of I professor of food science and human nutrition. That alarming finding means that three-fourths of the 18- to 25-year-old college applicants surveyed are at risk for metabolic syndrome, the researcher said...
Staggeringly Low Uptake Of HPV Vaccine Points To Failures In Patient Education, Vaccine Programs
Date: Mar-18-2013Completion rates for the human papillomavirus (HPV) vaccine series across both genders continue to remain alarmingly low nearly seven years after its introduction, suggesting that better patient education and increased public vaccine financing programs are needed, according to new research from the University of Texas Medical Branch (UTMB). The researchers report "startling" trends in a series of three separate studies published in Cancer, Human Vaccines & Immunotherapeutics and Vaccine...
Link Between Smoking And Worse Urothelial Cancer Prognosis, Especially For Women
Date: Mar-18-2013Smoking significantly increases individuals' risk of developing serious forms of urothelial carcinoma and a higher likelihood of dying from the disease, particularly for women. That is the conclusion of a recent study published in BJU International. While the biological mechanisms underlying this gender difference are unknown, the findings indicate that clinicians and society in general should focus on smoking prevention and cessation to safeguard against deadly cancers of the bladder, ureters, and renal pelvis, especially in females...
Oils And Fats Regulate Feeling Of Satiety, But Olive Oil Works Best
Date: Mar-18-2013Reduced-fat food products are gaining in popularity. More and more people are choosing "light" products in an attempt to lose weight, or at least in the hope that they will not gain any pounds. But whether these products are effective or not is a matter of dispute: While it is true that they contain fewer calories, people tend to overcompensate by eating more if they do not feel full. Now a study has shown how "natural" oils and fats regulate the sensation of feeling full after eating, with olive oil leading the way...
