VCU Researchers Design New Receptor And Enhance Bioassay To Advance Dr
Virginia Commonwealth University chemists have created a new molecular receptor for a fluorescent dye used to track a drug candidate's activity inside cell membranes. Understanding Malarial Parasites
Scientists have constructed a chaperon interaction network for the parasite which provides, for the first time, a rational basis for the antimalarial effect of known drugs and highlights new proteins that can potentially be used in the fight against malaria. Urologists Study Fluorescent Dye, Blue Light To Detect Bladder Tumors
One of the challenges urologic surgeons face when treating early bladder cancers is that they can't see tiny tumors during procedures to remove larger tumors. Missing the tiny tumors increases the chances that the cancer could recur, sometimes as early as three months after treatment. International Experts Cite Shortcomings In Pediatric Pain And Palliati
Advances in pain and palliative care for adults have been significant in the past decade due in part to increased recognition, support and use by caregivers and patients. While acknowledging that lessons from adults can be borrowed to help pediatric patients, an international team of pediatric palliative care specialists is also calling for increased research to address children's differing physical, psycho-social and clinical needs. PET/CT Brings New Hope To Patients With Deadly Form Of Breast Cancer
Researchers are improving the chances of women faced with an aggressive and difficult to diagnose form of breast cancer. Inflammatory breast cancer spreads quickly and can be lethal in six to nine months. But by using fluorodeoxyglucose positron emission tomography combined with computed tomography, radiologists and physicists are able to spot the spread of cancer earlier. [Ironic] An Italian pensioner committed suicide after his wife fell in
Recalling the end of Romeo and Juliet, the 70-year-old man, Ettore, who had sat by his wife's bedside for four months after she slipped into a coma following a heart attack, finally gave up hope and gassed himself in the garage of his family home.Less than a day later, his wife, Rossana, woke up in her hospital bed in Padua and immediately asked for him. MicroRNA Tweaks Protein That Controls Early Heart Development
Researchers at UT Southwestern Medical Center have discovered how a small molecule of RNA called microRNA - a chemical cousin of DNA - helps fine tune the production of a key protein involved in the early development of heart muscle. [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." Forsyth Scientists Find Three Bacteria Associated With Oral Cancer; En
Scientists at the Forsyth Institute have found that three bacterial species are associated with the most common form of oral cancer -- a discovery the researchers hope will lead to a simple diagnostic test for the often-fatal disease. Bacteria Employ Type Of DNA Modification Never Before Seen In Nature
Scientists have discovered that bacteria employ a type of DNA modification never before seen in nature. For several decades, researchers have known that it is possible to modify synthetic oligonucleotides (short strands of DNA) by adding sulfur to the sugar-phosphate DNA backbone as a phosphorothioate. Researchers often use such modifications in the laboratory to make DNA resistant to nucleases (enzymes that snip DNA in certain locations) as a step toward gene and antisense therapies of human diseases. Scientists were surprised to discover that a group of bacterial genes, known as the dnd gene cluster, gives bacteria the ability to employ the same modification on their own.
