Researchers found endostatin treatment reduced invasive head and neck cancer cells by half and their migratory capabilities by one-quarter. The study suggests an implanted drug delivery system could provide sustained therapeutic drug levels directly to tumors.
Researchers found that musicians played at a tempo closer to fast music when listened to before playing, while speakers read faster or slower after hearing a recording's speaking rate. Both groups unconsciously coordinate timing to find a mutually agreeable tempo.
NIST researchers are investigating detection devices to detect dirty bombs and radiation threats, ensuring accuracy in various conditions. The new standards will improve the calibration of detectors, reducing errors in measuring high, medium, or low energy radiation sources.
Researchers from Johns Hopkins Bloomberg School of Public Health developed the Diamond Graph method to correct long-standing errors of 3-D bar graphs. The new method represents all variables equally on a 2-D graph using expanding polygons within a diamond-shaped grid.
A recent study found that nearly 10% of female Army recruits tested positive for chlamydia, with rates increasing over time, highlighting the need for regular screenings and treatments to prevent long-term health consequences like pelvic inflammatory disease and infertility.
Researchers at Johns Hopkins Medicine discovered that altering leptin's signaling pathway can minimize or even reverse left ventricular hypertrophy, a condition causing the heart to expand and stiffen. Leptin infusions led to weight loss and improved heart function in mice with obesity, while caloric restriction had no effect.
Research suggests that schizophrenia impairs habitual prospective memory, leading to high rates of non-adherence to medication. The study found that people with schizophrenia are more likely to forget to turn over a counter during an obstacle course test.
A new study by the University of Pennsylvania School found that guggulipid, a traditional herbal remedy, has no impact on lowering cholesterol levels. The research suggests that dietary supplements need rigorous testing for safety and efficacy, with further studies planned to investigate its effects on triglycerides and inflammation.
Researchers found that administering hydroxyurea to patients with severe forms of beta-thalassemia boosted hemoglobin levels and enabled five patients to stop undergoing transfusions. The treatment also improved quality of life for the children, who reported feeling better and more active.
NIST has developed a way to accurately measure retroreflectivity, resolving measurement problems that hindered defining minimum standards. The new facility will provide calibration services early in 2004.
The NIST-developed device detects single photons with negligible dark counts using a tungsten film coupled to fiber optic communication line. It achieves a detection rate of 20,000 photons per second with an efficiency of 20%, aiming for over 80% improvement.
A study found that 41% of web sites selling ephedra products failed to disclose potential adverse effects or contraindications, while 53% did not reveal the dosage of ephedra alkaloids. The authors recommend that makers of dietary supplements containing ephedra should voluntarily disclose pertinent information about the supplements.
Researchers suggest celestial processes dominate climate change, with cosmic rays influencing low-level cloud formation and blocking sun warming. Human-caused greenhouse gas emissions are secondary to natural forces.
A recent study found that providing Medicare coverage to previously uninsured adults increases access to life-saving preventive tests like cancer and cholesterol screenings. The gap in testing rates narrows significantly after eligibility.
A team led by UC Riverside geneticist Dr. Close will deliver advanced information and material resources for barley genomics, aiming to make the barley genome accessible to everyone. The four-year project focuses on accessing expressed genes in Triticeae genomes using reliable methods.
Researchers found that hypnosis did not provide better pain relief compared to non-hypnotic treatments. The amount of pain relief experienced was largely due to participants' expectations from the therapy, according to the study's lead author.
Researchers tracked Miss Pearl's epic journey and welcomed her back to her nesting beach in Nicaragua after three years, gaining crucial insights into hawksbill sea turtle behavior and habitat protection. The satellite transmitter on Miss Pearl's back provided vital information on her location and diving patterns.
Researchers found that infant falls can produce significant rotational forces that cause widespread and serious brain injury, including internal bleeding and nerve cell damage. This challenges the assumption that children respond similarly to head trauma as adults.
Researchers at Ohio State University found that endostatin can stop Kaposi's sarcoma cells from growing new blood vessels and migrating through the body. The study suggests a controlled release of endostatin could be an effective treatment option for patients with KS.
A study revealed 253 Caribbean marine species are endemic, with many having tiny ranges making them susceptible to extinction. Destructive fishing practices and development threaten these micro-endemic species.
Researchers debated changes to cervical cancer screening guidelines as a vaccine for human papillomavirus (HPV) showed promising results. The study found that vaccination combined with biennial screening was cost-effective and reduced cancer incidence and mortality.
A new study by Northwestern University researchers reveals that nearly 80% of patients have a moderate or high genetic risk for adult-onset conditions. Using family history questionnaires and three-generation pedigrees, the team identified twice as many individuals at increased risk than documented in patient charts.
A new study finds that istradefylline, an adenosine A2A receptor antagonist, improves motor function in Parkinson's disease patients with reduced dyskinesias. The medication reduces the time patients experience tremors, slowness, and stiffness by up to 1.7 hours per day
