No-scalpel vasectomies by skilled surgeons may speed recovery

...nd patients, there are no definitive statistics to confirm the superiority of this choice, and a new review's main conclusion is to underline the importance of training. Yet training is not always available or sought, said lead reviewer Dr. Lynley Cook, a public health physician and clinical senior lecturer...

New cigarette designs don't offer lower predicted cancer risks

Pamela Clark, Ph.D., senior research scientist at Battelle Centers for Public Health Research and Evaluation in Baltimore, said Pankow's study "has profound implications for tobacco product regulation." Clark studies ...

Antibody signal may redirect inflammation to fuel cancer

...ely also lung and breast cancer," she said. "If we confirm that what we've discovered in the mice studies also occurs in human cancers, we may soon be in a good position to slow this cancer process using drugs already under study for severe immune disorders." Coussens envisions a therapeutic strategy simi...

The connector rotation hypothesis? Phage do not pack their DNA by rotation

Moonlighting enzyme linked to neurodegenerative disease

...edreich's ataxia. In addition, further study could confirm the presence of mutations in the enzyme that could explain, in part, differing clinical phenotypes among patients. Dr. Isaya says: "Understanding protein function is central to being able to provide individualized clinical care to patients who may...

New test helps identify hepatitis C patients at high risk of developing cirrhosis

...Stanford University School of Medicine has helped confirm the reliability of a new test for liver disease that is ushering in the long-promised era of personalized medicine based on each individual's genetic makeup. The Stanford group was one of the five sites that helped determine that the genetic test...

Scientists identify a candidate gene for osteoporosis

...loodstream. This causes a reduction in BMD. To confirm the involvement of DARC in regulating BMD, Mohan's team characterized the skeletal phenotype of mice with and without the DARC gene. The DARC -knockout mice exhibited increased BMD and lower bone resorption compared to mice with the DARC gene,...

A sweet step toward new cancer therapies

...ein was built---information that helps researchers confirm the protein's identity. This works fine as long as the protein has not been modified after it was produced. But if other chemical groups such as phosphates, sulfates or sugars have been added, the identification method breaks down. "If sugars are ...

Novel experiment documents evolution of genome in near-real time

Heavy smoking cuts women's chance of pregnancy -- even with donated oocytes

...ossible this is not a real association. What would confirm it as a real association is to find it still applies in a large number of cases. However, if it is confirmed as a real association it suggests that, paradoxically, tobacco constituents affect the uterus in different ways in different women, impairing...

Who gives stem cells their marching orders?

...ent research from Northwestern University seems to confirm this, showing that aggressive melanoma cells secrete the Nodal protein. Understanding the activity of this gene in embryonic development may hold the key to finding a way to control its activity in tumor cells. "We need to separate the aspects of Nod...

'GreeneChip' -- New diagnostic tool that rapidly and accurately identifies multiple pathogens

... Had the GreeneChip been available in the field to confirm the correct pathogen, the patient could have been treated for malaria. Differential diagnosis of hemorrhagic fevers poses challenges for clinical medicine and public health. Syndromes associated with agents are not distinctive, particularly early...

Hopkins scientists link immune response to 'ghost' parasites and severely congested sinuses

"This finding does not mean that there are actually parasites in the nose causing sinusitis, but our study does lend support to the concept that really severe and persistent sinusitis may be a case of a misplaced immune res...
