In the present study, we investigated the effect of a new anticancer Pd(II) complex, 1,10-phenanthroline-n-butyl dithiocarbamato Pd(II) nitrate, on the heme releasing from human hemoglobin (Hb) as well as alterations in the structure and function of Hb using different spectroscopic methods of UV-Vis, fluorescence and circular dichroism (CD)at two temperatures of 25 and 37 °C. Fluorescence data ...
Background: In most cancer cases, the treatment choice for a pregnant patient is radiotherapy. In these patients, the abdomen is usually not exposed therefore fetus exposure is due to peripheral dose (PD). The purpose of this study was to estimate the fetal dose (the maximum PD in each pregnancy stage) for modalities available and to fabricate and evaluate a generally applicable fetal ...
Background: Parkinson Disease (PD) is characterized by motor and non-motor symptoms that affect patients’ functions, especially while performing dual tasks--a critical factor in everyday living. However, many controversies exist about the benefits of dual-task training in patients with PD. Objectives: This study assessed the efficacy of motor and cognitive dual-task training in improving balanc...
objective(s):parkinson's disease (pd) is known for motor impairments. but often, there are non-motor symptoms such as cognitive deficiency and pain misperception, owing to possible role of nigrostriatal pathway. antioxidants have protective effect on free radical-induced neuronal damage in pd. to further address, we examined the effects of ellagic acid (ea) in a rat model of pd induced by ...
در آشکار‌ساز CMS نسبت‌های انشعاب بوزون هیگز مدل استاندارد به جفت‌‌های J/ψ(1S) و cc ترتیب برابر 2-10×1/8 2-10×2/89 اندازه‌گیری شده است. لحاظ نظری یکی از سناریوهای ممکن برای تولید مستقیم این است که آغاز جفت واپاشی نماید سپس مرحله‌ی بعد هر یک کوارک‌های c طور مزون ترکش کنند. بر اساس سناریو مقاله بطریق کوارک‌های با استفاده نظریه اختلال مکانیک کوانتومی رنگ (pQCD) نظر گرفتن حالت‌های قطبش طولی عرضی محا...
هیدروفرمینگ لوله به‌طور گسترده، در تولید قطعات ساختاری اتومبیل استفاده می‌شود. یکی از خصوصیات تولید‌شده با این فرایند، نسبت استحکام به وزن بالا می‌باشد. لولۀ فشار پایین، روش‌های پیشنهاد‌شده برای حل مشکلات قبیل نیاز بالای سیال و آب‌بندی روش انجام پایین لوله، شبیه فشردن جسم جامد است آن برخلاف بالا، قالب بالایی طول فرایند ثابت نبوده هم‌زمان اعمال داخلی حرکت کرده را تحت قرار می‌دهد. مقاله، لوله‌های...
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...
