Researchers analyzed daily weather and mortality data for 11 eastern US cities, finding that mortality risk increased with temperature extremes. Cities in the North were more sensitive to heat, while Southern cities were more vulnerable to cold temperatures.
Researchers at Stanford Medicine developed a system to study genetics and evolution in natural populations using the three-spine stickleback fish. They found parallels between laboratory genetics and evolutionary changes in the fish, suggesting that evolution can occur through large-effect gene changes.
A study found that alcohol use significantly raises the risk of death for both passengers and operators on recreational boats. Drinking while on a boat impairs an individual's ability to rescue themselves, increasing the chances of drowning and hypothermia.
Researchers found that a chemical signal from the nervous system can redirect immune actions, affecting conditions like arthritis and asthma. The discovery suggests potential for developing drugs to regulate the immune response and improve defenses.
The study reveals that new graduates spend less time looking for work, with most finding jobs within the Earth and space sciences. The majority are engaged in research, with many reporting high job satisfaction due to intellectual challenge and opportunities for continued learning.
A study by the University of Pennsylvania School of Medicine found that telling a lie and telling the truth require distinct brain activities. The research used fMRI to track brain activity in volunteers during an interrogation method, revealing increased activity in regions involved in inhibition and control when lying.
Researchers have confirmed that ancient prokaryotic potassium channels may be the precursor to modern mammalian potassium channels. The study, published in Nature, challenges the long-held assumption that these channels are similar across eukaryotes and prokaryotes.
Researchers discovered that the Nf1 gene serves two major purposes: preventing tumor growth and regulating the body's rest-activity cycle. In its absence, the body is unable to keep time, highlighting a crucial role of Nf1 in maintaining circadian rhythm.
A clinical study using human fetal tissue transplants suggests that the procedure may be logistically feasible and procedurally safe for patients with syringomyelia cavities. The study's primary goal is to evaluate the safety of transplantation with respect to possible early complications and long-term consequences.
Georgetown University's five-year program aims to enhance understanding of CAM practices, increase self-awareness, and improve communication with patients. The initiative will incorporate CAM principles into basic science courses and require all first-year students to take a Mind-Body Medicine course by year five.
A UCSF study of exclusive receptive oral intercourse with a male partner found a very low probability of acquiring HIV. The study involved 198 participants, none of whom contracted HIV through oral sex.
A new UNC study pinpoints the eed gene as crucial for female embryo survival by keeping the paternal X chromosome inactive and regulating genes in early placental cells. Female embryos without a functioning eed do not survive due to problems with forming placentas.
A UCSF study reveals that uninsured patients with chronic illnesses face significant challenges in managing their conditions, including poor symptom recognition and limited access to medication. This can lead to greater illness severity and premature death. Free community clinics are crucial for addressing these disparities.
Researchers at the University of Pennsylvania School of Medicine found that activation of vitamin A receptors can regulate the human circadian clock. This discovery provides an important clue to how the master clock in the brain regulates distal organs by controlling clocks throughout the body.
The UCSF Center aims to improve nursing care for older Americans by training more gerontological nurse scientists. The center will prepare nurses to educate future nurses and conduct research on aging health care policy.
A new UCSF study reveals that while combination antiretroviral therapy has improved patient outcomes, it also creates uncertainty and anxiety among healthcare providers. The researchers found that providers are struggling to make informed decisions due to a lack of resources and limited information on patient adherence.
A new study by the Gladstone Institute of Neurological Disease and UCSF team found that apoE3 can inhibit memory problems associated with Alzheimer's disease, while apoE4 cannot. This discovery could lead to the development of new drugs simulating apoE3's protective quality.
Nursing home residents with low nurse staffing have higher incidence of health problems, including urinary catheter use, skin care, and malnutrition. Experts recommend increased staffing, education, and training to improve quality care.
Researchers found that brain steroid allopregnanolone mediates many of alcohol's effects, including anti-anxiety and anticonvulsant actions. The study suggests that blocking this compound may inhibit alcohol's sedative-hypnotic effects.
The Annals of Internal Medicine's Millennium Issue explores various facets of time, including its impact on physician time management and patient care. The issue delves into alternative views of time, highlighting the need for a more holistic approach to medicine.
Researchers have discovered that myosin VI moves backwards on actin filaments, toward the minus end, challenging current understanding of protein movement. This finding has significant implications for our understanding of cellular assembly and maintenance, particularly in structures with single-orientation actin filaments.
A multi-center study found that people infected with human T-lymphotropic virus type II (HTLV-II) are at a greater risk of acquiring bronchitis, bladder and kidney infections, oral herpes, and pneumonia. HTLV-II is primarily found in injection drug users and Amerindian tribes in South and Central America.
A study found that 56% of HIV-infected gay men in the US are using combination therapy, but many are delaying treatment due to concerns about commitment and side effects. The study showed a strong link between advanced HIV infection and use of combination therapy.
Researchers found that female drivers are involved in slightly more crashes than male drivers, with males being three times more likely to be killed in car crashes. However, the study also revealed that after age 35, female drivers were at a greater risk of a crash than their male counterparts.
