A child sits on a bed surrounded by a bed net intended to prevent mosquito bites that could transmit malaria, Kenya. A new drug regimen developed at UCSF offers children improved protection against the disease.
Study shows that monthly doses of two common anti-malarial drugs for the first few years of life can provide 95 percent protection against the disease.
(left to right) The Galega officinalis (aka French lilac)was used as a folk remedy for diabetes symptoms for centuries before analysis of its extracts revealed compounds that lowered blood sugar. Eventually, metformin (molecule and pill) was developed. It is a related molecule that is longer acting and less toxic than the plant extracts. Metformin acts on cells in the liver (center and cross-section right) to reduce glucose production and thus blood sugar.
In people with type 2 diabetes, the body is less able to use the hormone insulin to regulate blood sugar. The disease affects 350 million patients globally—including 29 million in the United States, where it is the leading cause of blindness, kidney failure, and non-accident-related amputations.
In these multiple images of P. aeruginosa biofilm a bacterial community that takes the form of mushroom-like structures. The main, upper left image looks down at the biofilm, the lower, right-hand images show cross-sections. This biofilm was cultured from the airways of a patient with cystic fibrosis.
Nearly every human bacterial infection—including some of the most serious, life threatening, and costly to treat—can take the form of a biofilm, in which bacteria aggregate into structured communities that enclose themselves within a secreted slime.
Spiked rods of uric acid crystals from synovial fluid photographed under a microscope with polarized light. In patients with gout, such crystals can accumulate in the joints, causing pain and inflammation.
Allopurinol, the first-choice medication for treating gout—an excruciatingly painful condition that is the most common form of inflammatory arthritis, afflicts more than eight million Americans, and is on the rise worldwide—is not fully effective in more than half of patients.
I teach and precept pharmacy students and work with underserved populations at Zuckerberg San Francisco General Hospital. My research focuses on the clinical application of cardiovascular pharmacogenetic tests and pharmacoepidemiology.
