The supplementary motor area (SMA) is a key structure involved in behavioral planning and execution. Although many reports have indicated that SMA is organized somatotopically, its exact organization remains still unclear. This study aimed to functionally map SMA using functional magnetic resonance imaging (fMRI) and validate the fMRI-SMA by electrocortical stimulation (ECS) and postsurgical sy...
هدف: هدف از انجام این پژوهش استفاده از سلول های شبه عصبی حرکتی و سلول های مزانشیمی مشتق از بافت چربی بیان کننده gdnf در درمان نخاع ضایعه دیده با روش کانتیوژن که در فاز حاد والپروئیک اسید دریافت کرده اند، می باشد. یافته ها: سلول ها بعد از تمایز به سلول های بنیادی عصبی و سلول عصبی حرکتی مارکر های مربوط به رده های سلولی عصبی (نستین ، نوروفیلامنت 68 و نوروفیلامنت 160) و شبه عصبی حرکتی ( oligo-2,...
Social media analytics (SMA) can provide an organization with insights that would generate greater customer value and subsequently lead to better organizational performance and, thus enable the organization to have a competitive advantage over its rivals. In this paper, we develop a conceptual SMA capability framework which identifies SMA capabilities that an organization should have in order t...
OBJECTIVES Spinal Muscular Atrophy (SMA) presents challenges in (i) monitoring disease activity and predicting progression, (ii) designing trials that allow rapid assessment of candidate therapies, and (iii) understanding molecular causes and consequences of the disease. Validated biomarkers of SMA motor and non-motor function would offer utility in addressing these challenges. Our objectives w...
Waste fibers produced from manufacturing processes are a byproduct commonly deposited in storing yards and/or landfills and thus results in many serious environmental problems in Iran. If these waste materials could be advantageously put to practical use in any application, it would reduce the burden on the environment and landfills. This paper compares the performance of the stone matrix aspha...
There are two different ways of using SMA wires as actuators for shape control of flexible structures; which can be either embedded within the composite laminate or externally attached to the structure. Since the actuator can be placed at different offset distances from the beam, external actuators produce more bending moment and, consequently, considerable shape changes with the same magnitude...
BACKGROUND AND PURPOSE Some patients who undergo surgical resection of portions of the supplementary motor area (SMA) have severe postoperative motor and language deficits, whereas others have no deficits. We tested the hypothesis that in some patients with lesions affecting the SMA, the contralateral SMA exhibits some of the activation normally associated with the ipsilateral SMA. METHODS Fu...
Guaranteeing the use of Shape Memory Alloys (SMA) in mitigation of extreme load effects requires a deep study of the SMA behavior according to the specific requirements of the application. In particular, for a storm is necessary more than one million of working cycles. It is applied to two realistic cables in ELSA (JRC-Ispra, Italy) and in IFSTTAR (old LCPC in Nantes, France). The measurements ...
This report describes a new finding regarding language-Supplementary Motor Area (SMA) in language processing using robust clinical protocols i.e. word generation (WG) and sentence generation (SG). This is a retrospective study on 7 patients referred for fMRI for preoperative language mapping. Subjects ranged in age from 20 40 years (28.8 ± 7.3), mean ± SD. We quantified the dimensions of langua...
