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.

Cancer :: Re-educating immune system cells slows tumour growth

Immune system cells recruited by cancers to help them grow and spread could be ‘re-educated’ to attack the tumours instead of aiding them, Cancer Research UK scientists announced at the National Cancer Research Institute (NCRI) Conference in Birmingham.

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.

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.
