background: parkinson's disease as a progressive disorder of the nervous system leads to the disability of postural control system. objectives: in the present study the effects of pilates exercises on functional balance in patients with parkinson's was investigated. materials and methods: this control trial included 30 patients with idiopathic parkinson's disease who were selecte...

In  this  study,  amino  functional  groups  were  chemically  bonded  to  the  surface  of  newly synthesized  KIT-6  mesoporous  magnetite  nanoparticles  (MMNPs)  by  post-toluene  reflux synthesis method.  This method  treats  calcined mesoporous  nanoparticles with  the  functional organosilanes.  Physical  and  chemical  structures  of  the  synthesized  mesoporous  magnetite nanoparticle...

This study tested the hypothesis that hybridization of intraradicular dentin eliminates interfacial gaps, thereby improving the coronal seal and retention of teeth restored with fiber posts. Post spaces were bonded with two types of fiber posts, using the corresponding etch-and-rinse adhesives and dual-cured resin cements. Longitudinal sections of the interfaces were examined for dentin hybridi...

The dinuclear mol-ecule of the title complex, [VOCl{μ-OC(Me)2P(iPr)2-κ(2) O}]2 or [V2(C9H20O2P)2Cl2O2], which was obtained due to an unexpected oxidation reaction, is centrosymmetric, with the inversion centre located in the middle of the central V2O2 core. These core O atoms arise from the symmetry-related 2-(diiso-propyl-phosphor-yl)propan-2-olate dianions. The V(IV) atom is additionally bond...

The best plan for success is to begin with the end in mind. It generally is agreed that the successful treatment of a badly broken down tooth with pulpal disease depends not only good endodontic therapy, but also on good prosthetic reconstruction of the tooth after endodontic therapy. The primary purpose of the post is to retain a core that can be used to retain definitive prostheses. A post an...
