Basal levels of nuclear localized, tyrosine phosphorylated Stat5 are present in healthy human breast epithelia. In contrast, Stat5 phosphorylation is frequently lost during breast cancer progression, a finding that correlates with loss of histological differentiation and poor patient prognosis. Identifying the mechanisms underlying loss of Stat5(More)
Type I interferons (IFN alpha and IFN beta) are presently used in the adjuvant treatment of several human cancers. However, these cytokines have demonstrated only modest success in breast cancer therapy, and research efforts have focused on improving their efficacy. Recent progress in understanding the molecular mechanisms underlying the antiproliferative(More)
BACKGROUND Adult granulosa cell tumors of the testis (AGCTT) are classified as sex cord-stromal tumors. Only 31 cases have been reported. Typical presentation includes a slowly enlarging, painless testicular mass. Associated findings are gynecomastia, decreased libido, and erectile dysfunction. Immunohistochemistry can be used to confirm the diagnosis. (More)
Plantar fasciitis is a common cause of heel pain in the U.S. Army soldier, resulting in a significant loss of man hours. Given the heavy operations tempo of the U.S. military, successful treatment options need to be considered and used as quickly as possible. Plantar fasciitis can be successfully treated in up to 90% of patients using conservative measures.(More)
Epithelioid osteoblastomas (EOB) typically arise in the axial skeleton of young adults, but there are rare case reports of the lesion arising in soft tissue. To date, only 1 case has been reported in the skin, and it has been debated in the literature if that case was truly a neoplasm. With the availability of the new osteoblastic marker SAT2B, the authors(More)
Type I interferons (IFNa and IFN/3) are presently used in the adjuvant treatment of several human cancers. However, these cytokines have dem onstrated only modest success in breast cancer therapy, and research efforts have focused on improving their efficacy.
