Oral Acyclovir in the Treatment of Verruca.

Objective: To describe a case in which persistent plantar warts resolved after a ten-day treatment course of oral acyclovir prescribed for herpes zoster.

Case Summary: A 49 year-old Caucasian female with non-significant past medical history presented to the podiatry clinic for treatment of verrucae. Debridement was performed and monochloroacetic acid was applied to affected areas seven times over seven months.

Signal transducer and activator of transcription 3 activation is associated with bladder cancer cell growth and survival.

Background: Constitutive activation of signal transducer and activator of transcription 3 (Stat3) signaling pathway plays an important role in several human cancers. Activation of Stat3 is dependent on the phosphorylation at the tyrosine residue 705 by upstream kinases and subsequent nuclear translocation after dimerization. It remains unclear whether oncogenic Stat3 signaling pathway is involved in the oncogenesis of bladder cancer.

Signal transducer and activator of transcription 3 is involved in cell growth and survival of human rhabdomyosarcoma and osteosarcoma cells.

Background: Stat3 has been classified as a proto-oncogene and constitutive Stat3 signaling appears to be involved in oncogenesis of human cancers. However, whether constitutive Stat3 signaling plays a role in the survival and growth of osteosarcomas, rhabdomyosarcomas, and soft-tissue sarcomas is still unclear.

Methods: To examine whether Stat3 is activated in osteosarcomas, rhabdomyosarcomas and other soft-tissue sarcomas we analyzed sarcoma tissue microarray slides and sarcoma cell lines using immunohistochemistry and Western blot analysis, respectively, with a phospho-specific Stat3 antibody.
