Researchers at the University of Maryland Greenebaum Cancer Center have linked the PTEN gene to endometrial cancer in a study published in Nature Genetics. The findings suggest that up to 50% of all endometrial cancers may contain a mutation in this gene, highlighting the potential for improved detection and treatment options.
Researchers from the University of Pittsburgh analyzed blood samples and found no difference in homocysteine levels between men who suffered heart attacks and those who did not. The study suggests that homocysteine may be more closely linked to atherosclerosis or inflammation rather than promoting processes leading to heart disease.
A Virginia Tech project seeks to increase the number of women in science fields by recruiting middle school girls and teachers in five Southwest Virginia counties. The program aims to promote gender equity and provide role models for girls interested in science education.
Researchers Paul Richards and Won-Young Kim analyze seismic data to verify the Comprehensive Test Ban Treaty, concluding the event was an earthquake with 'excellent' monitoring capability
Researchers identified two critical periods of high error rates: before dawn and mid-afternoon. By understanding these patterns, workplaces can design jobs that exploit human strengths while protecting against attentional lapses caused by sleep deprivation.
Researchers have developed an electronic 'nose' that can detect the presence of pulmonary infection in patients with high accuracy. The device uses breath samples analyzed by multi-element odor detectors to identify unique patterns on a computer screen, distinguishing infected patients from non-infected ones.
Researchers at Duke University Medical Center have successfully revived flagging heart cells in laboratory vials using gene therapy. The treatment, which targets a protein kinase involved in heart muscle contraction, shows promise as a potential new drug target for treating congestive heart failure.
A study of over 1,700 older adults found a strong association between frequent religious services and lower levels of inflammation. Researchers discovered that attending church regularly was only half as likely to have elevated interleukin-6 levels, which can indicate immune system dysfunction.
The Plowshares Project enhances the US Army's Janus combat simulation model for emergency management events. TERRA simulates disasters and models effects on population and property. It also simulates individual field units and their actions in response to emergencies, facilitating interagency cooperation.
The MiCK assay measures how light scatters off of leukemia cells to determine the effectiveness of drugs being used to attack the cells. This technique allows for more accurate identification of which drugs will be most effective for each patient, revolutionizing leukemia therapy.
A workshop at UBC brought together faculty and graduate students from the Pacific Institute for the Mathematical Sciences (PIms) with industrial partners to solve six practical problems. The team successfully identified a better way to identify cancerous lesions in lungs, reducing mortality rates.
A University of Cincinnati geologist presents evidence from ancient volcanic ash beds indicating a narrow Iapetus Ocean existed during the Ordovician period. The discovery contradicts previous theories that the ocean disappeared due to landmasses being locked together.
The University of Maryland Medical Center has successfully implanted a new device that can regulate a dangerously rapid heartbeat automatically and internally. The Metrix System TM delivers a small electrical shock to the heart, making it a more comfortable alternative to external shocks.
Researchers at UT Southwestern Medical Center found that glucocorticoid can inhibit expression of TNF-alpha gene, halting inflammation and autoimmune diseases like rheumatoid arthritis and lupus. Understanding this mechanism could lead to better drugs with fewer side effects.
A study found that seniors with depression in HMOs receive fewer mental health specialist visits and are prescribed benzodiazepines instead of newer antidepressants. This disparity may be due to cost-containment strategies, highlighting the need for better care for vulnerable elderly patients.
Researchers discovered a protein sensitive to chemical stimuli and tissue-damaging levels of heat, identifying capsaicin as the key player. The cloned gene enables large-scale production of the protein, paving the way for potential pain-controlling drugs.
