A new study from the University of Washington found that generalists are more likely to provide primary care to elderly Medicare patients, suggesting an approach at the center of most managed-care plans. Specialists tend to restrict themselves to medical problems specific to their specialty and rarely immunize their patients.
A University of Toronto study found that 35% of all homes and 20% with children and daily smokers were smoke-free in 1996. Despite this, only 50% of homes with daily smokers had no smoking rules, highlighting the need for parent education programs to reduce exposure to environmental tobacco smoke.
A study found that teenagers who identify as gay, lesbian or bisexual are more likely to report engaging in multiple risky behaviors and starting them at an earlier age. These teens also experience higher rates of emotional distress, including missed school due to fear and physical threats.
Researchers at The Wistar Institute have identified a key role for the GA733 antigen in inhibiting colorectal cancer cell invasion. The discovery has led to the development of an antibody that increases survival rates for CRC patients.
Researchers at the University of Illinois have created a highly symmetrical molecular box with an internal volume of about 132 angstroms, opening new dimensions for host-guest chemistry. The boxes are easily dissolved and can be modified to be negatively or positively charged for future sensing technology applications.
A new study found that people who eat low-fat lunches compensate by eating more fat or carbohydrates at other meals, leading to similar daily fat and carbohydrate intake levels. The brain's biochemical signals play a major role in food choices, particularly where fat, carbohydrates, and total calories are concerned.
The first investigation of estrogen metabolism in prostate cancer will determine if differences exist between healthy men and those with the disease. The study aims to find potential new strategies to prevent this important disease.
According to a recent study, 80% of poisoning deaths in the US are caused by drugs, with opioids and cocaine being the leading causes. The death rate from poisoning increased by 25% between 1990 and 1995, with the peak age group being 35-44 years.
A slowdown in health spending growth is expected to have a significant impact on health workers and local economies. The shift in job composition within the health sector, towards lower-paying sub-sectors and jobs such as home health services, will exacerbate the issue.
Researchers identify neurotransmitter-triggered electrical activity as a key signal for synapse formation in embryonic spinal cord neurons. The activity is necessary for clustering glycine receptors, which are essential for inhibitory neurotransmission in the spinal cord.
The study found that blood cell precursors originate soon after mesoderm cells appear in the embryo, suggesting a new understanding of blood cell development. The discovery also revealed that definitive red blood cell precursors can be found in the yolk sac before they appear within the embryo.
Researchers are utilizing a jellyfish gene to develop more efficient methods for inserting desirable genes into sugarcane plants. The gene, known as green fluorescent protein (GFP), allows scientists to quickly identify the effectiveness of genetic modifications.
