Artificial Livers A Step Closer
Date: Jun-04-2013Prometheus, the mythological figure who stole fire from the gods, was punished for this theft by being bound to a rock. Each day, an eagle swept down and fed on his liver, which then grew back to be eaten again the next day. Modern scientists know there is a grain of truth to the tale, says MIT engineer Sangeeta Bhatia: The liver can indeed regenerate itself if part of it is removed...
In Multiple Sclerosis-like Disease, Enhanced White Blood Cells Heal Mice
Date: Jun-04-2013Genetically engineered immune cells seem to promote healing in mice infected with a neurological disease similar to multiple sclerosis (MS), cleaning up lesions and allowing the mice to regain use of their legs and tails. The new finding, by a team of University of Wisconsin School of Medicine and Public Health researchers, suggests that immune cells could be engineered to create a new type of treatment for people with MS...
Higher-Producing, Better-Tasting Chocolate Likely Following Genome Sequencing Of Cacao Plant
Date: Jun-04-2013The freshly sequenced genome of the most commonly cultivated cacao plant in the world is revealed in the open access journal Genome Biology. Researchers have utilised high quality DNA sequences to demonstrate the usefulness and quality of the sequence to identify genetic markers that can lead to higher yielding cocoa plants that still produce better tasting cocoa. There are many varieties of the cacao tree (Theobroma cacao L.), but the green podded Costa Rican Matina or Amelonado variety is the most popular because of its high yield and pleasant flavor...
A Grassy Trend In Human Ancestors' Diets
Date: Jun-04-2013Tooth Enamel Shows Surprising Change in Our Ancient Buffet Most apes eat leaves and fruits from trees and shrubs. New studies spearheaded by the University of Utah show that human ancestors expanded their menu 3.5 million years ago, adding tropical grasses and sedges to an ape-like diet and setting the stage for our modern diet of grains, grasses, and meat and dairy from grazing animals...
Vitamin D Tests And Deficiency: New Patient Resource For GPs
Date: Jun-04-2013A new patient information leaflet on vitamin D deficiency will be available from next week for GPs to use with their patients. The leaflet is part of a suite of resources developed for the latest NPS MedicineWise educational program on preventive activities in general practice. Vitamin D testing is one of several medical tests appraised in the program that focuses on preventive health in 40 - 49 year olds. It encourages GPs to prioritise evidence-based risk assessments and tests, and avoid inappropriate testing that may cause more harm than good...
News From The Annals Of Internal Medicine: June 4, 2013
Date: Jun-04-20131. Daily Sunscreen Use Slows Skin Aging - Even in Middle-Age For the first time, science proves that daily sunscreen use significantly slows skin aging, even in middle-aged men and women. Sunscreen and antioxidants have long been advocated to prevent skin aging, but to date, there has been no scientific evidence of their effectiveness. Researchers measured photoaging of 903 participants younger than 55 to determine whether regular use of sunscreen would slow skin aging compared with discretionary application...
Increased TV Exposure Associated With Higher Consumption Of Sweetened Beverages Among Children
Date: Jun-04-2013More time in front of the TV set and higher exposure to TV adverts may lead to increased consumption of sweetened beverages among children. This is the conclusion of a new study from the University of Gothenburg, Sweden. The parents of more than 1,700 two- to four-year-olds in Sweden responded to questions about their children's TV and screen habits and consumption of sweetened drinks...
Cancer Pain Eased By Therapy That Heats And Destroys Bone Tumors
Date: Jun-04-2013Patients with cancer that has spread to their bones are often treated with radiation therapy to reduce pain. But if that treatment doesn't work, or can't be used again, a second, effective option now exists. Results of a clinical trial on the new therapy, presented by a researcher at Jefferson's Kimmel Cancer Center, was presented at the annual meeting of the American Society of Clinical Oncology (ASCO)...
MarginProbe System Makes Breast Cancer Surgery More Precise
Date: Jun-04-2013Any breast cancer surgeon who regularly performs lumpectomies confronts the question "Did I get it all?" Thirty to 60 percent of the time in the U.S., the answer is "no," requiring the patient to undergo a second surgery to remove the remaining tumor. Surgeons at UC Irvine Medical Center are the first in the country to use a device that reduces by half the need to reoperate and cut out breast cancer cells missed during an initial lumpectomy. The MarginProbe System lets the surgeon immediately assess whether cancer cells remain on the margins of excised tissue...
In Metastatic Uveal Melanoma, New Drug Improves Progression-Free Survival, Shrinks Tumors
Date: Jun-04-2013The experimental drug selumetinib is the first targeted therapy to demonstrate significant clinical benefit for patients with metastatic uveal melanoma, according to new Memorial Sloan-Kettering Cancer Center research presented at the 49th annual meeting of the American Society of Clinical Oncology (ASCO). The findings are potentially practice-changing for a historically "untreatable disease...
