A new protein called HveC has been discovered that allows both Herpes Simplex-1 and -2, as well as animal herpesviruses, to infect human cells. This receptor has the broadest activity among the identified co-receptors, enabling entry of multiple strains of herpesviruses into various cell types.
A Duke University Medical Center pharmacologist finds that maternal smoking causes massive numbers of crib deaths and severe neurological problems in
Scientists have discovered a species of glowing bacteria that can detect pollutants in the deep sea. When exposed to various toxic substances, Photobacterium phosphoreum HE-1a glows up to 50% less brightly, triggering an alarm call that alerts nearby sensors to take action.
A study published in JAMA found that injured patients have a much higher death rate after leaving the hospital than the general population. This suggests that deaths after discharge should be included in any meaningful analysis of a trauma center's quality to get an accurate picture of its success.
Researchers found a correlation between multiple cardiovascular risk factors and the severity of atherosclerosis in children and young adults. Selective screening for high-risk individuals is recommended. Healthy lifestyle choices, such as diet and exercise, are crucial to preventing coronary heart disease.
A microbiological process developed by Penn State researchers can effectively remove perchlorate, a rocket fuel ingredient detected in 14 states, from contaminated drinking water. The process uses naturally occurring bacteria to reduce perchlorate concentrations below the action level.
The American Chemical Society will present over 225 technical papers on various topics including medical isotopes, environmental fate of aircraft de-icing fluids, and smart materials. A banquet and minority affairs workshops are also planned for the event.
A computer network manager proposes using obsolete ICBMs to create spectacular pyrotechnic displays, releasing thousands of artificial meteors into the atmosphere with different colours depending on their chemicals. The plan aims to reuse Cold War relics for entertainment rather than scrap them.
A new study from Penn State found that families with patients in the early stages of Alzheimer's disease are more likely to accept available treatment, whereas those with advanced-stage patients may choose to withhold care. The study also highlighted the need for family involvement in making treatment decisions.
A comprehensive review article by Stephen S. Hecht summarizes the biochemistry, biology, and carcinogenicity of tobacco-specific nitrosamines, linking them to lung cancer formation. The article highlights the importance of understanding these compounds for developing effective chemoprevention strategies and targeted prevention methods.
A study challenges the widely accepted pediatric practice of prescribing a 10-day course of antibiotics for uncomplicated ear infections, suggesting that five days of short-acting oral antibiotics are equally effective. The researchers found no significant difference in treatment failure rates when comparing the two treatment courses.
A recent study found that women in public housing lack factual knowledge about specific health risks and benefits of quitting. Concerns about general health were the primary motivator for quitting, but perceptions of addiction hindered actual plans to quit.
A synthetic detergent, nonylphenolethoxylate (NPE), commonly used in household cleansers, has been discovered to block a drug pump in cancer cells, reducing the need for chemotherapy drugs. The researchers found NPE present in human urine and suggest it could be a useful adjunct to standard treatments.
A research team has identified a critical weakness in the defence against aging and discovered that a specific cell type, the motor neuron, is the major target for oxidative damage. By inserting a human gene into fruit flies, researchers were able to boost their lifespan by 40%.
A survey of 60,000 Pennsylvania students found a decrease in willingness to seek help from physicians, parents, teachers, and counselors for drug abuse treatment. Students' perception of the risks associated with drugs has decreased over time, but the actual problems persist.
Scientists have created gene-altered mice that closely reproduce the clinical features of dilated cardiomyopathy, allowing for unprecedented study of early changes and development of new therapies. The model enables researchers to understand the causes and mechanism of the disease, ultimately aiming to develop more effective treatments.
Researchers developed a model to predict antiviral drug resistance in genital herpes, finding that treating the disease would prevent more cases than developing resistant strains. The study suggests using this methodology for other infectious diseases prone to resistance.
A study by National Jewish researchers found that families with unexpressed emotions and disorganization are more likely to have children with asthma who skip taking medication. The researchers also found that knowledge of asthma's symptoms and treatments alone is not enough to ensure a child will take medication as prescribed.
Researchers at Temple University have found that spatial attention can improve motor and language tasks in individuals with aphasia who have parietal lobe lesions. This means that directing attention to the correct location can enhance performance on various cognitive tasks, including sensory, naming, and reading tasks.
