PURPOSE The purpose of the present study was to evaluate the effect of root planing on the reduction of probing pocket depth and the gain of clinical attachment depending on the pattern of bone resorption (vertical versus horizontal bone loss) in the interproximal aspect of premolar teeth that showed an initial probing pocket depth of 4-6 mm. METHODS In this study, we analyzed 68 teeth (15 fr...

CONTEXT Invasion of the bifurcation and trifurcation of the multi-rooted teeth resulting in furcation involvement is one of the serious complications of periodontitis. AIM The purpose of the study was to evaluate the efficacy of combination therapy using anorganic bovine bone graft and resorbable guided tissue regeneration (GTR) membrane versus open flap debridement alone in the management of...

a one-month-old male terrier dog was referred in shock status with a history of anorexia, tachypnea, abdominal distention and progressive weight loss. auscultation of right side of the lungs found enhanced respiratory noises. the thorough auscultation of the opposite side of the chest revealed the presence of typical intestinal sounds. cardiac auscultation revealed muffled heart sounds and a di...

venturi flumes are measurement structures commonly used in water systems to measure the flow discharge. some of them are not well installed or present some geometrical defects. the objective of this study is to investigate the hydraulic influence of a number of typical wrong installations and geometrical defects of long-throated venturi flumes: significant positive or adverse slopes, humps and ...

graphene sheet including single vacancy, double vacancy and stone-wales with armchair and zigzag structure was simulated using molecular dynamics simulation. the effect of defects on shear’s modulus, shear strength and fracture  strain was investigated. results showed that these shear properties reduce when the degrees of all kinds of defects increase. the dangling bond in sv and dv defected gr...

This work is focused on the effect of natural defect fatigue resistance a laser powder bed fusion additively manufactured Ti-6Al-4V titanium. To reveal strength variability and its sensitivity to size, push-pull tests have been undertaken specimens with different sizes highly loaded volume material. In order easily vary size volume, containing numbers surface hemispherical shape holes 600 ?m in...

OBJECTIVES The reconstruction of large full thickness chest wall defect after resection of T3/T4 non-small cell lung cancer (NSCLC) or primary chest wall tumours presents a technical challenge for thoracic surgeons and is a critical factor in determining post-operative outcome. When the defect is large, complications are common with a 27% mean rate of respiratory morbidity. METHODS Since 2006...

Aim . To study the immediate results of extended modified mastectomy with closure soft tissue defect in chest wall using patient’s tissues diffuse forms breast cancer. Materials and methods Advanced by thoracodorsal lower abdominal horizontal flap on rectus abdominis was performed 24 patients Results discussion Primary healing wounds observed 21 (87,5%) patients. Marginal necrosis displaced fou...

Self-assembling, light harvesting arrays of organic chromophores can be templated using the tobacco mosaic virus coat protein (TMVP). The efficiency of energy transfer within systems containing a high ratio of donors to acceptors shows a strong dependence on the TMVP assembly state. Rod and disk assemblies derived from a single stock of chromophore-labeled protein exhibit drastically different ...
