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.
