Researchers at the University of Georgia found that cross-immunity between dengue strains explains the timing of epidemics, with an average three-year cycle and seasonal component. The study provides a new framework for creating models to predict dengue outbreaks in various regions.
A research team from Massachusetts General Hospital has discovered a potential drug target for Huntington's disease by identifying a novel inhibitor of Poly(ADP-ribose) polymerase (PARP1). PARP1 inhibitors can protect HD-affected cells from damage and energy depletion in laboratory assays.
Researchers found that nurses experience debilitating low back pain, especially in orthopedic and ICU settings, with 65% of orthopedic nurses developing the condition. Providing access to mechanical lifting devices and redesigning hospital rooms could help prevent such injuries.
Researchers develop computer approach to precisely target breast tumors with electron and x-ray beams, reducing collateral skin damage. The technique helps send accurately targeted doses for 78 patients, providing benefits for shallow tumor treatments in the breast, chest wall, and head-and-neck region.
Scientists have identified a regulator of genes that controls artery smooth muscle cell growth, which may hold the key to preventing vessels from re-closing after angioplasty. By studying genetically susceptible pigeons, researchers found a potential target for treating restenosis.
Researchers have created a new genetic model for Parkinson's disease using mice with a deleted TFAM gene, which mimics the human condition. The study shows that dopamine-producing nerve cells in the brain stem degenerate slowly, similar to humans with Parkinson's disease.
Researchers at Iowa State University have developed a process to turn manure and corn stalks into a bio-oil that can be used as boiler fuel and potentially transportation fuel. Preliminary tests show promising results, with every kilogram of dried mixture producing .2 to .5 kilograms of bio-oil.
Aerial mosquito spray increased the toxicity of pyrethroids in creeks by doubling their effects. Researchers found that a chemical synergist, piperonyl butoxide (PBO), made sediments more toxic to certain aquatic species.
Researchers at Penn's new Center for Spirituality and the Mind are examining the effectiveness of meditation on early cognitive impairment. They will combine meditation with brain imaging to see if it improves cognitive function and is associated with actual change in the brain's activity levels.
Researchers at MIT's Picower Institute for Learning and Memory have developed a state-of-the-art imaging system that allows them to directly visualize molecular activity within individual neurons in the brain of live animals. This breakthrough enables the observation of changes in neuronal activity in response to environmental stimuli,...
Researchers at Indiana University School of Medicine – Northwest propose that a family of proteins producing PGLYRP can be used to develop medications for HIV/AIDS patients. These proteins appear to be the front line in defending the body from infection, mounting a defense long before the body's main immune system responds.
Researchers have developed a new approach to treating gliomas, deadly brain tumors, by delivering radioactive iodine using a man-made version of scorpion venom as a carrier. The treatment targets glioma cells without affecting neighboring tissue or body organs and has shown promise in Phase I clinical trials.
Scientists believe that high runoff from hurricanes in 2004 contributed to the development of extensive and long-lasting red tides off west-central Florida. Groundwater discharge is thought to provide the necessary nutrients for these blooms, explaining their persistence and frequent occurrence in the region.
Researchers from Hospital Clínic de Barcelona found that a 8-year Ivermectin treatment reduced onchocerciasis prevalence by 38.4%, while incidence of disease decreased by 2.6 times in children aged 0-4. The study, financed by the Spanish Agency and WHO, marks a significant step forward in combating river blindness.
Recent studies examine voting gaps in America, finding significant differences in support for George W. Bush based on race, ethnicity, religion, class, region, gender, age, and education. The research also explores the impact of class divisions, the religion gap, and the urban-rural divide.
A recent study by UK researcher Cerel explores the connection between parental death and psychiatric problems in children. The results indicate that while bereavement has a negative impact, it is less severe than clinical depression.
