The folate receptor, a protein expressed on the surface of many human cells, could be capable of transporting much more into the cell than just folic acid - the B vitamin involved in normal bodily functions and cell development.
California's tobacco control program is "stalled and adrift," and thousands of people will die needlessly as a result, according to a new report published by the Institute for Health Policy Studies in the School of Medicine at the University of California, San Francisco.
Highly active anti-retroviral therapy (HAART), also known as "AIDS cocktail" therapy, is saving lives and preventing infections even in the most advanced AIDS patients, according to a new study.
Compared to insured health care consumers, uninsured people are much less effective at managing their illnesses.
Controlling a tuberculosis infection requires an interplay of a distinct set of genes and immune system cells. Researchers at the Gladstone Institute of Cardiovascular Disease are showing for the first time that the absence of one of those genes, called CCR2, can have fatal consequences.
Researchers are showing for the first time that the absence of the gene for CCR2, a receptor on white blood cells known to be important for cell migration, can have fatal consequences.
UCSF researchers report that they were able to slow the growth of human cancer cells - or cause them to commit suicide altogether -- by creating just a miniscule mutation in the telomerase enzyme.
Our cells constantly flirt with disaster: Before each division, they duplicate hundreds -- often thousands -- of DNA snippets from each chromosome...
More than half of sexually active young women will be infected with human papilloma virus (HPV) if they remain sexually active over three years, a UCSF study shows. That risk is boosted 10-fold with each new partner.
UCSF researchers have discovered a human gene that can be traced back through the mouse to the fly, illuminating a molecular nugget from ancient times that may play a crucial role in male fertility - and infertility.
Scientists have identified the gene that prompts embryonic stem cells to generate precursors to most internal organs.
Some postmenopausal women carry a gene sequence that may lower their risk of breast cancer, according to new research from San Francisco Veterans Affairs Medical Center.
UCSF researchers have found that HIV-infected homeless and marginally housed people who have trouble sticking to their antiviral regimens may temporarily delay the onset of full blown AIDS if they manage to take at least half of their anti-HIV medications.
A recent increase in severe reactions to the street drug "Ecstasy" has prompted the San Francisco division of California Poison Control System (CPCS) to renew alerts about the drug's dangers.
Cancer screening guidelines that recommend a test based on age are too simplistic, argues a new study from the San Francisco Veterans Affairs Medical Center.
HIV-positive women are three times more likely than other women to develop lesions that can lead to anal cancer, new research shows. The greater risk is due at least in part to weakened immune defenses against the common sexually transmitted human papillomavirus (HPV).
Many older adults dread colon cancer screening, because the most effective screening tool, colonoscopy, is uncomfortable and invasive. A new study from San Francisco Veterans Affairs Medical Center shows that a faster, safer, and potentially more pleasant technique works just as well.
A single exposure to cocaine triggers a week-long surge of activity in a brain region central to the development of addiction, according to new research on mice published this week in Nature. The changes may prime the brain for addiction, the researchers say.
HIV that has become resistant to powerful drugs called protease inhibitors may not be a dire sign of decline after all, researchers from the Gladstone Institute of Virology and Immunology have shown.
A drug widely prescribed as the sole treatment for asthma has been found to be incapable by itself of preventing asthma attacks or controlling the airway inflammation thought to lead to deteriorated lung function and gradual worsening of asthma.
The Center for Mothers and Newborns and UCSF Children's Medical Center will star in a new documentary that features high-risk deliveries and natural childbirth, a "miracle" baby born after five miscarriages...
CHICAGO - Many frail elderly women who get routine mammography suffer significant burdens from the screening procedure with little chance to benefit from it, says a study from researchers at San Francisco Veterans Affairs Medical Center.
Pediatricians know that most of the health damaging threats to children in their teenaged years can be prevented if teens avoid dangerous risks and habits. Training can increase the number of times that health providers will put that knowledge into practice.
HIV infection among injection drug users (IDUs) in San Francisco is strongly associated with sexual behavior, with men who have sex with men (MSM) and women who trade sex for money much more likely to become infected than other IDUs, according to a study by UCSF researchers.
African American and Hispanic senior citizens who lack prescription drug benefits are three times more likely than white seniors to cut back on taking their medications, according to a study from researchers at San Francisco Veterans Affairs Medical Center.
Men who have sex with men (MSM) who are victims of childhood sexual abuse are more likely to engage in risky sexual behavior than other MSMs, say researchers from UCSF's Center for AIDS Prevention (CAPS).
The first patent for a method of delivering normal genes in a pill to induce the production of insulin in people with diabetes was issued May 1 to the University of California, San Francisco by the United States Patent and Trademark Office.
Researchers led by UCSF scientists are reporting that a highly effective clot busting drug for stroke is significantly underutilized in all patient populations at U.S. academic medical centers, and is strikingly underutilized in African Americans.
Simplifying women's access to hormonal contraceptives such as the pill would improve women's health, according to a UCSF study that appears in today's issue of the Journal of the American Medical Association (JAMA).
The highways and byways through which the brain exchanges messages require maintenance much as any municipal road. What would happen if such debris were left to accumulate? Alzheimer's disease would result.
