Parkinson’s disease (PD) is a progressive neurological disorder characterized by tremor, rigidity, and slowness of movement. Recent studies on investigation of the brain function show that there are spontaneous fluctuations between regions at rest as resting state network affected in various disorders. In this paper, we used amplitude of low frequency fluctuation (ALFF) for the study of intra-r...
Introduction: Parkinson Disease (PD) is a degenerative and progressive disorder of the central nervous system. It results from degeneration of Substantia Nigra pars compacta (SNc) of the Basal Ganglia (BG). Gait disturbances in PD patients generally get worse over time. The underlying mechanism of gait disturbances in PD has not been elucidated yet. Methods: In this study, we tried to analyze ...
Introduction: We investigated correlation between the retinal nerve fiber layer (RNFL) thickness and the severity of Parkinson's disease (PD). Methods: In this study, the RNFL thickness of 23 patients with Parkinson’s disease (PD) was compared to normal controls (NCs). PD severity was assessed by the MDS-UPDRS (movement disorder society Unified Parkinson Disea...
introduction: long-term levodopa treatment of parkinson’s disease (pd) is frequently complicated by spontaneously occurring involuntary muscle movements called dyskinesia. the exact pathological mechanism of this complication has not yet been elucidated. we have previously demonstrated that in pd patients the vulnerability to develop peripheral but not orofacial dyskinesia is associated with th...
آنیون پنتاسیانونیتروزیل فرات (pcnf) که معمولاً با نام نیتروپروساید بدان اشاره می شود، یکی از معرف-های سیانومتالاتی به شمار می رود. نیتروپروساید های فلزی، دسته ای از ترکیبات فلزی با ظرفیت مختلط هستند که در بسیاری از موارد خواص مشابهی با هگزاسیانوفرات های فلزی نشان می دهند. در این کار پژوهشی، اصلاح الکترود آلومینیوم پالادیزه (pd-al) با ترکیب آهن پنتاسیانونیتروزیل فرات (fepcnf) بر اساس یک فرآیند ...
کمبود گلوکز-6-فسفات دهیدروژناز( pd 6 g ) ناهنجاری آنزیمی شایع و وابسته به کروموزوم x می باشد. pd 6 g اولین آنزیم کلیدی در مسیر پنتوز فسفات است که در تولید nadph دخالت دارد. nadph در بیوسنتز گلوتاتیون احیا شده( gsh ) از اهمیت زیادی برخوردار می باشد. gsh از دناتوراسیون هموگلوبین جلوگیری کرده، از گروه های سولفیدریل غشای گلبول های قرمز محافظت می کند و عاملی برای رفع مسمومیت پراکسید هیدروژن و رادیکا...
Introduction: Neuroinflammation may play as an important risk factor in progressive degeneration of dopaminergic cells. Antioxidants have protective effects against free radicalsinduced neural damage in Parkinson’s disease (PD). In the present study, we examined the effects of ellagic acid (EA) on locomotion and neuroinflammatory biomarkers in a rat model of PD induced by 6-hydroxidopamin...
Background: There is little information about the survival rate of pediatric peritoneal dialysis (PD) patients and its risk factors. Therefore, the aim of the present study was to assess survival rate and its risk factors in Iranian children undergoing PD. ...
Objectives: The present study aimed at investigating the relationship between Dysphonia Severity Index (DSI) and disease speech and voice severity of Parkinson disease (PD) patients. Method. This study was a cross-sectional ones, carried out on 45 PD patients with the age range of 50 to 75 years, who were randomly selected. The Hoehn and Yahr Scale (H.Y Scale) was employed to measure the le...
