ambits of tones (as one of the most important elements of mode structure) in old iranian music have multiple kinds and definitions. middle eastern musicologists have always tried to explain and devise tones ambits, because ambits of tones and structure of mode are irrefrangible. generally purpose of division of ambits to their components is explanation of melodic modules and their combination. ...

BACKGROUND The purpose of this study was to evaluate the effects of intravenous zoledronic acid applied systemically on osseointegration of dental implants and the surrounding bone mineral density (BMD) in the ovariectomized rats. MATERIAL AND METHODS 36 rats were divided into three groups: control (CTRL), ovariectomy (OVX), and ovariectomy-zoledronic acid (OVX/ZOL). The rats in the CTRL grou...

PURPOSE Clinical trials in early breast cancer have suggested that benefits of adjuvant bone-targeted treatments are restricted to women with established menopause. We developed models that mimic pre- and postmenopausal status to investigate effects of altered bone turnover on growth of disseminated breast tumor cells. Here, we report a differential antitumor effect of zoledronic acid (ZOL) in ...

The molecular mechanisms responsible for the cellular effects of the nitrogen-containing bisphosphonate zoledronic acid (Zol) were assessed on several osteosarcoma cell lines differing in their p53 and retinoblastoma (Rb) status. Zol inhibited cell proliferation and increased atypical apoptosis. The Zol effects on proliferation were due to cell cycle arrest in S and G2/M phases subsequent to th...

Cathepsin K (CatK) is essential for osteoclast-mediated bone resorption. CatK expression is also detected in breast cancer cells that metastasize to bone. Here, the CatK inhibitor L-235 dosed in prevention (10, 30, and 100 mg/kg, p.o., b.i.d.) or treatment regimen (30 mg/kg) was compared with the bisphosphonate zoledronic acid (ZOL, 7.5 μg/kg/wk, s.c.) in the intratibial injection model of MDA-...

Mycoestrogen zearalenone (ZEA) is found in human foods and animal feeds. Its estrogenic potencymainly depends on its biotransformation fate. The hepatic biotransformation of ZEA in rainbow trout wasinvestigated in this study. Various concentrations of ZEA were separately incubated with the hepaticmicrosomal and post-mitochondrial sub-fractions in the presence of NADPH, and the metabolites wered...

The long-term survival of osteosarcoma has remained unchanged in the last several decades. Immunotherapy is proved to be a promising therapeutic strategy against osteosarcoma, especially for those with metastasis. Our previous study explored the sensibilization of zoledronate (ZOL) in γδ T cell-mediated cytotoxicity against osteosarcoma, but we have not yet elucidated the specific mechanism. Be...

AIM To assess whether zoledronic acid (ZOL) adds to the effect of combined androgen blockade (CAB) in patients with hormone-naive bone metastatic prostate cancer. PATIENTS AND METHODS Patients were treated with either a combination of CAB (luteinizing hormone-releasing hormone agonist and bicalutamide) and ZOL (CAB-Z group) or CAB-alone (historical control patients, CAB-C group). ZOL was inje...

Zearalenone (ZEN) is a mycotoxin produced by Fusarium fungi. ZEN primarily contaminates different cereals, and exerts a strong xenoestrogenic effect in animals and humans. ZEN is a fluorescent mycotoxin, although molecular interactions and microenvironmental changes significantly modify its spectral properties. During biotransformation, ZEN is converted into α-zearalenol (α-ZOL) and β-zearaleno...

Nitrogen-containing bisphosphonates (N-BPs), which are usually used for the treatment of advanced cancer with bone metastasis, occasionally cause fever following the first administration. However, it is unclear as to how the development of fever following the first administration of N-BP is associated with clinical outcome. The aim of the present study was to determine the prognostic value of t...
