Researchers found that non-adherence to inhaled corticosteroid therapy is a significant issue in difficult-to-treat asthma patients. Women and those with lower quality of life scores were more likely to be non-adherent. Developing better objective tests for non-adherence is crucial, according to Dr. Liam Heaney.
Adult survivors of childhood cancer have a higher risk of suicidal thoughts even years after treatment, according to a study. Health problems in adulthood are strongly linked to suicidal thoughts in survivors, with poor health and chronic conditions increasing the risk.
Research published in the UK-based urology journal BJUI found that women exposed to DDT spraying were more likely to have sons with urogenital birth defects, which can cause missing testicles or problems with their urethra or penis. The study suggests that prolonged exposure to DDT may increase the risk of these defects.
Neurologists at the University at Buffalo are conducting a research study to test the possibility that chronic cerebrospinal venous insufficiency (CCSVI) is the underlying cause of multiple sclerosis. The study aims to evaluate the velocity of blood flow through brain vessels and extracranial veins using Doppler ultrasound.
Typhoon Lupit is forecast to move northeast, weakening due to cooler waters and wind shear. The storm will continue crawling at a slow pace, causing prolonged rain over northern Luzon this weekend.
The March of Dimes has established two new awards to honor established scholars in perinatal ethics and encourage young researchers to enter the field. These awards will focus on moral issues before, during, and after pregnancy, including reproductive technologies and neonatal care.
The Center for Social and Cognitive Networks will investigate social interactions, trust levels, and technology's impact on relationships. Rensselaer researchers will collaborate with top academic and corporate partners to build a firm scientific basis in network science.
A Spanish researcher analyzed wolf feces and found that 62.8% of prey was roe deer, while domestic sheep and goats only made up 7.7% and 2.9%, respectively. The study suggests that wolves do not prioritize easily available prey like domestic animals.
The ARVO Foundation for Eye Research and Pfizer Ophthalmics are honoring Dr. Carl B. Camras with a series of awards recognizing excellence in early-career researchers working on novel vision research. The awards aim to support the development of innovative treatments and prevention strategies for eye disorders.
A team of scientists has gained a better understanding of how Leishmania donovani parasites evade the human immune system, leading to chronic infection. This breakthrough could potentially lead to new treatments for visceral leishmaniasis, a fatal disease affecting millions worldwide.
A new study by Uppsala University researchers Elena Jazin and Björn Reinius found that genetic expression in cerebral cortices exhibits sex-based differences, which are thought to be associated with later divergences in brain development. The study suggests that genes on the Y chromosome play a crucial role in these differences.
The report analyzes the similarities, differences, potential impacts, and costs of current bills passed by Congress, including provisions for expanding coverage, improving quality, and controlling costs. The bills differ in how reform would be financed and what actions would be taken to control costs and expand coverage.
Despite high risk, older African Americans are less likely to get the flu vaccine due to lack of accurate information and lingering distrust from the infamous Tuskegee syphilis studies. This results in lower vaccination rates among this age group, with only 48% vaccinated compared to 65% for non-Hispanic white seniors.
Researchers found that depression-related genes and stress-related genes have almost no overlap, indicating that chronic stress does not cause the same molecular changes as depression. This finding challenges the long-held belief that stressful life events are a major cause of depression.
A workshop conducted by the National Cancer Institute and FDA identified critical decision points in cancer biomarker and drug development. The points emphasize the importance of understanding the biology of the target and its interaction with drugs, as well as rigorous sample collection and quality control.
A new study from Columbia University found that US patients are almost five times more likely to spend their last hospital days in the ICU than patients in England. The research also revealed that ICU usage among terminal patients is eight times higher in the US than in England, particularly among those over 85.
Tropical Storm Neki continues to exhibit intense areas of heavy rainfall despite weakening, according to NASA's TRMM satellite. Rainfall rates reached up to 2 inches per hour in the storm's northeast and northern quadrants.
A team of Harvard chemists has developed a new microscopic technique that allows researchers to identify previously unseen molecules in living organisms. The room-temperature technique uses stimulated emission to generate images of non-fluorescent molecules, offering broad applications in biomedical imaging and research.
The Great Diseases curriculum, funded by a $1.35 million NIH grant, introduces current global health threats through laboratory learning, multimedia, and case-based studies to 11th and 12th graders in three Boston high schools. The program aims to teach students how to think like scientists and generate interest in biotechnology careers.
