In migrating adherent cells such as fibroblasts and endothelial cells, the microtubule-organizing center (MTOC) reorients toward the leading edge [1-3]. MTOC reorientation repositions the Golgi toward the front of the cell [1] and contributes to directional migration [4]. The mechanism of MTOC reorientation and its relation to the formation of stabilized(More)
Mycobacterium tuberculosis causes active tuberculosis in only a small percentage of infected persons. In most cases, the infection is clinically latent, although immunosuppression can cause reactivation of a latent M. tuberculosis infection. Surprisingly little is known about the biology of the bacterium or the host during latency, and experimental studies(More)
BACKGROUND Previous studies using systematically administered lathyrogens to inhibit wound contractures have produced inconsistent results. The purpose of this study was to investigate the effects of lathyrogenic drugs on wound contraction when injected locally. METHODS Two symmetrical full-thickness wounds were made on the dorsum of either side of(More)
Eighty-five cases of tinea capitis due to T. tonsurans were observed in the San Francisco Bay area during the five years 1950-54. This disease, unlike the common microsporum infections, sometimes affects adults and adolescents. Hairs infected with T. tonsurans do not fluoresce under the Wood's light. Diagnosis is a laboratory procedure in which the fungus(More)
Severe facial burns cause significant deformities that are technically challenging to treat. Conventional treatments almost always result in poor aesthetic and functional outcomes. This is due to the fact that current treatments cover or replace the delicate anatomical facial tissues with autologus grafts and flaps from remote sites. The recent introduction(More)
