Oral Cancer :: USC School of Dentistry researchers discover link between oral cancer and ethnicity

Clinicians from the USC School of Dentistry unravel connection between the incidence of oral cancer and race and ethnicity– as part of first epidemiological study of oral cancer in California. Dr. Satish Kumar and Dr.Parish Sedghizadeh, clinical professors in the school’s Division of Diagnostic Sciences, gleaned through 20 years of records from the California Cancer Registry (CCR)—the state’s cancer surveillance database—for the incidence rates of invasive squamous cell carcinoma, the most common form of oral cancer.

Stem Cell :: Study Reveals How Stem Cells Decide To Become Either Skeletal or Smooth Muscle

Researchers have discovered a key protein that controls how stem cells “choose” to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels, according to a study published today in the Proceedings of the National Academy of Sciences (PNAS).

Depression :: Job factors, work environment can contribute to depression

Job stress and a lack of social support in the workplace were associated with major episodes of depression in men, according to a study led by a University of Rochester School of Medicine and Dentistry psychologist. In women, depression was linked to lack of decision authority on the job and low levels of social support.

Health :: UT Southwestern earns $34M NIH grant to foster patient-oriented research

UT Southwestern Medical Center will receive $34 million from the National Institutes of Health to lead a wide-ranging collaborative initiative aimed at speeding the transfer of laboratory discoveries to new therapies that improve human health.

Stem Cell :: Stem cells in tendons regenerate tissue

Athletes know that damage to a tendon can signal an end to their professional careers. But a consortium of scientists, led in part by University of Southern California (USC) School of Dentistry researcher Songtao Shi, has identified unique cells within the adult tendon that have stem-cell characteristics?including the ability to proliferate and self-renew.
