BACKGROUND Mitoxantrone-based chemotherapy palliates pain without extending survival in men with progressive androgen-independent prostate cancer. We compared docetaxel plus estramustine with mitoxantrone plus prednisone in men with metastatic, hormone-independent prostate cancer. METHODS We randomly assigned 770 men to one of two treatments, each given in 21-day cycles: 280 mg of estramustin...

Breast cancer resistance protein (Bcrp/Abcg2) is a new efflux transporter found at the blood-brain barrier (BBB) of humans and pigs. Since it has been hypothesized that Bcrp may act as a new type of efflux transporter at the BBB, we investigated the involvement of Bcrp in the efflux transport of typical substrates, dehydroepiandrosterone sulfate (DHEAS) and mitoxantrone, across the mouse BBB. T...

PURPOSE Acute myelogenous leukemia (AML) is a disease originating from normal hematopoietic CD34+ CD38- progenitor cells. Modulation of the multidrug ATP-binding cassette transporter ABCB1 has not resulted in improved outcome in AML, raising the question whether leukemic CD34+ CD38- cells are targeted by this strategy. EXPERIMENTAL DESIGN ABCB1-mediated transport in leukemic CD34+ CD38- cells...

PurposeMitoxantrone plus prednisone and ixabepilone each have modest activity as second-line chemotherapyin docetaxel-refractory castration-resistant prostate cancer (CRPC) patients. Clinical noncrossresis-tance was previously observed. Patients and MethodsMetastatic CRPC patients progressing during or after taxane-based chemotherapy enrolled in aphase I multicenter study of...

Present study investigated the possible role of P-glycoprotein in intracellular exposure of active substance (robinin) natural medicine Flaroninum™ and effect robinin on cellular accumulation mitoxantrone either BCRP-overexpressing BCRP-negative cells. Robinin - kaempferol-3-O-b-D-robinoside-7-O-α-L-rhamnopyranoside, has been obtained from over ground parts Astragalus falcatus Lam., growin...

A previous study suggested that drug release is the dominating factor controlling biological activity of liposomal mitoxantrone in tissues where the rate of liposome accumulation is rapid. The studies described here attempted to address the question: under conditions where the rate of liposome accumulation is slow, does drug release or liposome-mediated drug delivery become the dominant factor ...

M sclerosis (MS) is an autoimmune disease, involving predominantly the white matter of the brain and spinal cord. Approximately 85% of patients initially experience one or more relapses followed by complete or incomplete recovery; this clinical pattern is called the relapsing–remitting phase. Over 10 years, roughly 50% of these patients experience a transition to the secondary progressive phase...

patients and methods this cross-sectional study on 71 patients with ms was carried out between 2010 and 2012, in an iranian population. demographic and pharmacological variables were recorded in d-base. statistical analyses were performed using spss for windows. results the females/males sex ratio within the study population was 3.17: 1. the mean age of females was 32.2 years old (range 20 - 45...
