A study analyzing human genes reveals a wide range of sequence changes associated with blood pressure control and potential disease susceptibility. The research identified 50% of the changes that lead to protein structure alterations, suggesting their involvement in human disease.
A University of Iowa study found that nearly 70% of older Iowans received the flu vaccine, but only about half got the pneumococcal vaccine. The researchers identified factors such as age, marital status, and access to healthcare as associated with vaccination rates.
New research recommends a higher intake of vitamin C due to its role in preventing cardiovascular disease, cancer, and cataracts. Studies show that increased levels of vitamin C can reduce risk factors associated with these conditions, making it essential for overall health.
A study by Virginia Tech found that a $0.45 per-pack price increase for cigarettes leads to a 9% reduction in overall domestic consumption, with a notable impact on young smokers. The study suggests that the price hike will discourage youth from starting smoking and reduce existing habits.
A study of 5,888 senior citizens found that only those with high levels of atherosclerosis or diabetes and the ApoE4 gene are at high risk for cognitive decline. The majority of elderly people showed no significant decline in cognitive function over 10 years.
A study found that pine cones' spines hinder finches' ability to access seeds, encouraging seed dispersal. Researchers discovered a link between spine growth and the length of time seeds remain on pine cones.
Researchers at Johns Hopkins Medicine have discovered a natural compound called pigment epithelium-derived factor (PEDF) that offers nearly complete protection against amyotrophic lateral sclerosis (ALS). PEDF is a potent neurotrophic factor that may significantly protect spinal motor nerves against injury.
A new study by University of Michigan professor Dr. Arnold S. Monto found that zanamivir, an antiviral drug, is 67% effective in preventing laboratory-confirmed clinical influenza infection. The drug was also shown to be 84% effective in preventing laboratory-confirmed illnesses with fever.
Researchers at The Wistar Institute are developing vaccines targeting the mucosal immune system to prevent HIV-1 and human papilloma virus infections. They aim to induce neutralizing antibodies and killer T cells to prevent cancerous transformations in cells, with a focus on cervical cancer caused by HPV.
A new report from Dr. Anthony-Samuel LaMantia suggests a possible neuro-developmental theory of schizophrenia linked to altered brain development during the first three months of pregnancy. Abnormalities in retinoic acid signaling pathways may contribute to the development of schizophrenia.
Researchers developed a new test to identify reading difficulties caused by brain injuries, which passed with high sensitivity compared to existing assessments. The Iowa-Chapman Reading Test can detect even subtle reading problems in patients who have trouble reading despite passing other standard tests.
