(1) Background: since the technologies of anesthesia and surgery were advanced, video-assisted thoracic (VATS) under local (LA) has been widely carried out is considered a robust surgical technique to prevent recurrence pneumothorax in patients with recurrent primary spontaneous (PSP). In this study, postoperative clinical outcomes compared evaluate feasibility efficacy VATS LA general (GA) PSP...
مقدمه: تصاویر رادیوگرافی با کیفیت پایین، اطلاعات درمانی را مخدوش میکند که منجر به تکرار رادیوگرافی و اکسپوژر غیرضروری بیمار میشود. لذا بررسی اهمیت زمان اسکن تاخیری و شرایط نگهداری سنسورهای PSP در کیفیت تشخیصی تصویر مهم میباشد. مواد و روشها: در این مطالعه آزمایشگاهی شصت عدد رادیوگرافی دیجیتال با 12 عدد سنسور Digora PSP با سه نوع شرایط نگهداری محیط روشن و پوشش تیره، محیط روشن و پوشش شفاف و ...
Introduction & Objective: Diagnosis of periodontal osseous lesions is very important in deter-mining prognosis, treatment plan and maintenance in the long term. This diagnosis can be achieved by using radiography. The aim of this study is to compare accuracy of E speed films, bitewing PSP, panoramic PSP and CCD for identifying the extent of destruction of alveolar bone in chronic periodontiti...
The development of inhibitory synaptic transmission is difficult to assess because the afferents usually arise from intrinsic neurons that are difficult to stimulate independently. The postnatal maturation of excitatory and inhibitory synaptic function was compared in the gerbil lateral superior olive (LSO), where it is possible to stimulate physically discrete afferent projections. Intracellul...
We simulated the diffusion of glutamate, following the release of a single vesicle from a pre-synaptic terminal, in the synaptic cleft by using a Brownian diffusion model based on Langevin equations. The synaptic concentration time course and the time course of quantal excitatory post-synaptic current have been analyzed. The results showed that they depend on the number of receptors located at ...
OBJECTIVE For patients with high-grade glioma on clinical trials it is important to accurately assess time of disease progression. However, differentiation between pseudoprogression (PsP) and progressive disease (PD) is unreliable with standard magnetic resonance imaging (MRI) techniques. Dynamic susceptibility contrast perfusion MRI (DSC-MRI) can measure relative cerebral blood volume (rCBV) a...
Germline mutations in FLCN are responsible for ~10% of patients with primary spontaneous pneumothorax (PSP), characterized by multiple lung cysts in the middle/lower lobes and recurrent pneumothorax. These clinical features are also observed in a substantial portion of patients with sporadic PSP exhibiting no FLCN coding mutations. To assess the potential underlying mechanisms, 71 patients with...
Progressive supranuclear palsy (PSP) is a tau deposition neurodegenerative disorder which usually occurs in sporadic form and is associated with a common variant of the tau gene. Rare familial forms of PSP have been described. Recently familial frontotemporal dementia linked to chromosome 17 (FTDP-17) has been shown to be due to mutations in tau and there may be a clinical and pathological over...
Phosphodiesterase regulates the homeostasis of cAMP and cGMP, which increase the strength of excitatory neural circuits and/or decrease inhibitory synaptic plasticity. Abnormally, synchronized synaptic transmission in the brain leads to seizures. A phosphodiesterase 10A (PDE10A) inhibitor PF-2545920 has recently attracted attention as a potential therapy for neurological and psychiatric disorde...
