the concept of imagery is to make an image of successful movement skill or a relaxing image in mind with no body training and external experience. the aim of the present study was to compare the effect of traditional and pettlep mental imagery methods on static and dynamic balance. the statistical population consisted of all female university of tehran students who had general physical educatio...

OBJECTIVE To evaluate the effectiveness of demineralized bone matrix (DMBM), an osteoconductive and osteoinductive graft material, as a bone graft for the treatment of osseous defects, both clinically and radiographically. MATERIALS AND METHODS The effectiveness of DMBM was assessed at 40 sites in 30 patients who had infrabony defects. Grafted test sites were compared with control sites treat...

Potassium channels are dynamic proteins that undergo large conformational changes to regulate the flow of K(+) ions across the cell membrane. Understanding the gating mechanism of these channels therefore requires methods for probing channel structure in both their open and closed conformations. Radiolytic footprinting is used to study the gating mechanism of the inwardly-rectifying potassium c...

Evaluation of the clinical effects of scaling and root planing (SRP) alone or in combination with 0.2% chlorhexidine (CHX) rinsing. A blind, placebo-controlled, randomized clinical trial was conducted in 30 subjects with generalized chronic periodontitis. Subjects were assigned to two therapeutic groups: control (SRP + placebo) and test (SRP + CHX up to 42 days post-therapy). Sites (4–6 mm) in ...

aims and objectives: the present study was carried to evaluate the adjunctive effect of the local application of hyaluronan gel to scaling and root planing in the treatment of chronic periodontitis. materials and methods: twelve patients with chronic periodontitis participated in the study with a split mouth design. plaque formation and bleeding on probing (bop) were evaluated pre-treatment (ba...

We present a new approach to probing single-particle dynamics that uses dynamic light scattering from a localized region. By scattering a focused laser beam from a micron-size particle, we measure its spatial fluctuations via the temporal autocorrelation of the scattered intensity. We demonstrate the applicability of this approach by measuring the three-dimensional force constants of a single b...

This paper discusses two applications of probing dense volumetric data for MR orthopedics and dynamic contrast enhanced MRI mammography. In order not to reduce the context information and to extract the essential part of the data, we apply Profile Flags. A Profile Flag is a 3D glyph for probing and annotating the volumetric data. The first application area deals with visualization of T2 profile...

Introduction: It is important to preserve epithelial and connective tissue attachment at its original level after periapical surgery. The aim of this study was to compare the periodontal parameters after using the papilla base flap and the sulcular full-thickness flap procedures. Methods: Fourteen healthy patients with no periodontal disease referred for surgical treatment of periapical lesions...

background and aim: children with hearing loss and children with intellectual developme­ntal disorders have defects in organizing and sensory integration. the aim of this study was to evaluate the effects of hearing impairment and intellectual disability on children's static and dynamic balance. methods: this cross-sectional comparative stu­dy was conducted on 17 boys with congenital severe to ...
