Brain holds clues to bipolar disorder

...he brain is yielding vital clues to understanding, diagnosing and treating bipolar disorder, according to findings being presented today at the Seventh International Conference on Bipolar Disorder. Two studies, featured in a press briefing held at 12:15 p.m., Thursday, June 7, have helped to identify novel path...

Chemo combination improves survival in asbestos-related cancer

Study shows hope for early diagnosis of Alzheimer's

...activity, and turn it into a cutting-edge tool for diagnosing Alzheimer's disease," Kounios added. The team members hope that eventually they or other researchers will develop a hand-held device that can be used to conduct similar evaluations as those done by the Rowan/Penn//Drexel group. “We don’t envisi...

Scientists use nanoparticle to discover disease-causing proteins

...provide researchers with a more reliable method of diagnosing human diseases and developing new drugs. Purdue University researchers bound a complex nanomolecule, called a dendrimer, with a glowing identification tag that was delivered to specific proteins in living venom cells from a rattlesnake. The scientis...

New study may show how to forestall a fatal, virus-caused immune-system meltdown

...erwise.? Connecting those strands is critical to diagnosing and restoring balance to an immune system gone haywire in a disease like Lassa fever. “Early on, you can’t really differentiate these nasty hemorrhagic fever viruses from their symptoms ?they just resemble the flu,?Herzog said. “But if you have bioma...

Twin studies reveal genetic components leading to cardiac and kidney disease

Scientists map key landmarks in human genome

...help uncover important clues for understanding and diagnosing cancer and other diseases, the scientists say. Moreover, it may shed light on the role of nucleosomes in the process of "reprogramming" an adult cell to its original embryonic state, which is a critical operation in cloning. David E. Fisher, MD, PhD...

Hay fever can send work productivity down the drain

... the ImmunoCAP IgE blood test was more accurate in diagnosing allergies when compared to other specific IgE blood tests. While IgE testing is traditionally the realm of allergists, more and more family physicians are starting to use it, she said. But patients who think they may have allergies need to ask if ...

Nanoparticles can track cells deep within living organisms

...these could prove useful for monitoring tumors and diagnosing and treating cardiovascular problems. The nanoparticles contain a fluorine-based compound that can be detected by MRI scanners. Fluorine is most commonly known for being an element included in fluoride toothpastes. Wickline, who heads the Siteman ...

HIV dementia alarmingly high in Africa

...tain normative data for the cognitive tests. In diagnosing HIV dementia, researchers looked at medical history and the results of a series of comprehensive neurological and neuropsychological tests and functional assessments. "Clearly, large-scale testing would have to be conducted before we know the glob...

First biomarker for human sleepiness identified in fruit flies

...and provide clinicians with valuable new tools for diagnosing and assessing treatment efficacy in patients with sleep disorders." According to Shaw, sleepiness biomarkers will also prove useful to studies of sleep in animals. "Cetaceans like killer whales, for example, are known to go for extended periods...

Nanoparticle assembly enters the fast lane

... and data storage, as well as improved methods for diagnosing and treating disease. Learning how to control and tailor the assembly of these miniscule particles into larger functional systems remains a major challenge for scientists. The Brookhaven results, published online on October 11, 2006, by the Journal o...

Novel regulatory mechanism identified for key tumor suppressor p53

...bed in the study suggests intriguing approaches to diagnosing or intervening in the progression of many types of cancer. A report on the team's findings will be published online November 15 in the journal Nature. "The p53 protein is vital for controlling cancer throughout the body," says Shelley L. Berger, Ph...

Pure carbon nanotubes pass first in vivo test

...al that many researchers hope will prove useful in diagnosing and treating disease. The research will appear in this week's online edition of the Proceedings of the National Academy of Sciences. "We sampled tissues from a dozen organs, and found significant amounts of nanotubes only in the liver," said lead ...

Light-sensitive photoswitches could restore sight to those with macular degeneration

New GI technologies improve internal organ visualization

...rchers compared the two procedures for accuracy in diagnosing intestinal bleeding. During a capsule endoscopy, the patient swallows a small camera that records images of the intestinal tract. To complete a double balloon enteroscopy, doctors use a scope fitted with two balloons to navigate the entire small ...

Lack of basic research putting patients at risk

...instance, little is known about the reliability of diagnosing stroke and, until very recently, no reliable data existed on the early risk of stroke in certain patients. Countless patients have suffered as a result, yet much of this research is easy and relatively cheap to do, so why has it not been done, he ask...

Scientists seek to unwrap the sweet mystery of the sugar coat on bacteria

Genome sequencing is for ecologists, too

...rch in the human health sciences, with the goal of diagnosing the state of aquatic environments. Despite their common name, water fleas are not insects but crustaceans, like lobsters and crabs. Daphnia is the first crustacean genome to be sequenced. Information from its genome will help biologists make sense o...
