University of Florida researchers have reversed diabetes in mice by injecting cells that produce enough insulin to regulate blood sugar levels effectively. The cells were grown into small, insulin-secreting organs and implanted just beneath the skin, allowing them to function like an endocrine pancreas within days.
Researchers at the University of Florida have identified a possible pathway to protect heart cells from damage caused by doxorubicin, an anti-cancer drug. By understanding how caspases trigger cell death, they may develop targeted treatments using anti-oxidants like vitamins E and C.
The University of Toronto has discovered a new species of giant ground sloth, challenging the long-held assumption that mammals from South America were inferior to those in North America. The study suggests that these groups thrived for nearly two million years after migration across the Panamanian land bridge.
Patients with macular degeneration experienced improved moods and increased use of visual aids after completing a six-week behavioral self-management program. The program also boosted confidence in daily functioning and reduced symptoms of anxiety and depression.
A team of researchers at the University of Toronto has discovered a gene called Mgat5 that affects cancer growth. By knocking out this gene in mice, they found a significant reduction in breast and lung cancer growth, suggesting that sugar structures play a role in promoting tumor development.
Researchers found changes in brain cells in rats treated with anti-depressant and obesity drugs, including shriveling and abnormal corkscrew shapes. The study raises concerns about the prolonged use of such commonly prescribed drugs as fluoxetine and sertraline.
Researchers found that intelligent adolescents tend to postpone any kind of lesser sexual activity, as well as first sex, compared to their less intelligent peers. The association between intelligence and refraining from sexual intercourse was stronger for girls than boys, and age-dependent.
The EPA has chosen Washington University in St. Louis to monitor fine particle matter air pollution in the St. Louis metropolitan area, as part of a comprehensive and collaborative program. The project aims to investigate relationships between pollutants and human illnesses, including cardiovascular disease and pulmonary illnesses.
A new study found that 32-35% of patients in weight loss, headache, and chronic pain programs dropped out due to factors like emotional distress and low self-efficacy. The researchers suggest investigating variables such as support from family and friends, and the therapeutic alliance between clients and program leaders.
A new study suggests that open family discussion about stressful thoughts and feelings can improve emotional well-being in kidney transplant patients. Patients who felt their families were supportive reported fewer symptoms of depression and anxiety.
Researchers at Duke University developed heat-triggered liposomes that can deliver anti-cancer drugs to tumors, delaying growth and eradicating human tumors in mice. The new technology uses specially engineered liposomes that release their cargo rapidly when heated to temperatures just above normal body temperature.
A new study links lower socioeconomic status, measured by education level, to increased psychological factors like hostility. This may lead to poor health outcomes due to increased physiological activity or strain, as well as unhealthy behaviors such as smoking.
Researchers found that two-thirds of unnecessary antibiotic prescriptions were given to patients with negative throat cultures. Inaccurate diagnoses and lack of immediate diagnostic tools contribute to the problem. Experts blame current diagnostic methods and advocate for improved solutions.
Individuals treated for depression use fewer routine medical services, but more outpatient services than the general population, according to a 10-year analysis. Treatment is associated with reduced non-routine medical utilization over time.
Researcher Professor Heather Jackson spent 15 years studying marginalia in books to uncover insights into cultural and reading habits of the past. Her findings suggest that handwritten notes left in books can be a valuable source of historical information, providing unique perspectives on authors' intentions and readers' reactions.
A new study by Robert Pearson, Howard Wachtel, and Kristie Ebi found that children living near heavily trafficked streets have a six-fold increased risk of developing childhood cancer. The researchers used street-traffic densities to assess exposure to air pollutants from vehicle emissions.
A new study by the University of Toronto found that children who had a daily activity program in Grades 1 to 6 showed no advantages in aerobic fitness 20 years later. The study highlights the importance of developing lasting skills and attitudes in physical education programs.
