Abstract   Background: To evaluate proximal junctional segment changes in Adolescent Idiopathic   Scoliosis(AIS) the posterior spinal fusion and also instrumentation also and   finding of probable risk factors, were all considered in this study.   Methods: We retrospectively reviewed radiographs of 121 consecutive patients   who underwent posterior spinal fusion for AIS from T3 or below, with...

Introduction: Intramedullary nailing (IMN) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. However, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated IMN fixation of proximal high tibia fracture. The purpose of this study is to determine the effectiveness of using 3.5-mm locking c...

Background: Anterior cruciate ligament (ACL) reconstruction using tendon or ligament autograft is the current goldstandard surgical technique for acute ACL ruptures. However, ACL repair surgical procedures are reappearing as anoptimistic treatment alternative for acute proximal ruptures. The purpose of this annotation is to review the current roleof primary repair of the ACL.<...

Provisional hypomyopathic juvenile dermatomyositis is a subgroup of clinically amyopathic juvenile dermatomyositis provisional. The diagnostic criteria include: Classic dermatomyositis skin lesions – which have to be confirmed by biopsy –, no involvement of proximal muscles, subclinical involvement of these muscles and normal level of muscle enzymes. These criteria should be present for a minim...

Non-convex and non-smooth optimization plays an important role in machine learning. Proximal gradient method is one of the most important methods for solving the nonconvex and non-smooth problems, where a proximal operator need to be solved exactly for each step. However, in a lot of problems the proximal operator does not have an analytic solution, or is expensive to obtain an exact solution. ...

originating from vygotsky’s sociocultural theory, dynamic assessment (da) proposes a novel approach to second language acquisition (sla) research according to which a dialectical relationship is envisaged between instruction and assessment. although da has been applied to some areas of sla, there are areas, such as interlanguage pragmatics (ilp), that have been neglected.  to address the issue,...

introduction: the aim of this study was to evaluate the effect of proximal contour of class ii composite restorations placed with straight or contoured matrix band using composite resins with different modulus of elasticity on stress distribution by finite element method. methods: in order to evaluate the stress distribution of class ii composite restorations using finite element method, upper ...

introduction: laryngopharyngeal reflux (lpr) is considered an important cause of voice disorder. we aimed to determine the frequency of lpr in patients with voice disorder and the association between koufman reflux symptom index (rsi), reflux finding score (rfs), gastroesophageal reflux disease (gerd), and proximal acid reflux in these patients. materials and methods: we performed a prospective...
