Background and Objective: Alzheimer’s disease (AD) is a degenerative disorder that leads to progressive cognitive decline. The memory dysfunction of AD has been associated with a cortical cholinergic deficiency and loss of cholinergic neurons of the nucleus basalis of Meynert (NBM). This study investigated the effect of ethanolic extract of Cyperus rotundu tubers (CRT) on motor activity in NBM-...
اثر تمرین استقامتی بر دستگاه تنفسی تا حدودی اثبات شده است، اما شواهد اندک و متناقضی در رابطه با تمرین مقاومتی (rt) وجود دارد، بنابراین هدف از تحقیق حاضر، مطالعه اثر هشت هفته rt به شیوه دایره ای (crt) بر عملکرد ریوی زنان غیرفعال بود. نوزده زن داوطلب غیرفعال سالم به طور تصادفی به دو گروه کنترل بدون تمرین (c) و crt تقسیم شدند. آزمایش اسپیرومتری ۲۴ ساعت قبل و پس از دوره تمرینی انجام شد. دوره تمرین ...
AIMS There are limited and contradictory data on the effects of CRT with implantable cardioverter defibrillator (CRT-D) on mortality as compared with CRT with pacemaker (CRT-P). METHODS AND RESULTS We evaluated the long-term outcome of patients implanted with a CRT-D or CRT-P device in our high-volume single-centre experience. Data on all-cause mortality were derived from clinic visits and th...
Abstract Funding Acknowledgements Type of funding sources: None. Background Concerns exist about the benefit cardiac resynchronization therapy with a defibrillator (CRT-D) compared to those without (CRT-P), especially in patients non-ischemic cardiomyopathy. We evaluated association between capability and all-cause mortality receiving (CRT) for Methods From nationally registered cardiomyopathy ...
Purpose: We used randomized trials of radiotherapy (RT) with or without chemotherapy in non-metastatic nasopharyngeal carcinoma to investigate the survival benefit of chemoradiotherapy regimens between two/three-dimensional radiotherapy (2D/3D RT) and intensity-modulated radiotherapy (IMRT). Methods: Overall, 27 trials and 7,940 patients were included. Treatments were grouped into seven categor...
OBJECTIVE To study whether subvolumes with a high pre-chemoradiotherapy (CRT) FDG uptake could identify residual metabolically-active volumes (MAVs) post-CRT within individual esophageal tumors. Accurate identification will allow simultaneous integrated boost to these subvolumes at higher risk to improve clinical outcomes. METHODS Twenty patients with esophageal cancer were treated with CRT p...
background: for the purpose of individual clinical target volume assessment in radiotherapy of prostate cancer, mrsi was used as a molecular imaging modality with mri and ct images. materials and methods: the images of 20 prostate cancer patients were used in this study. the mr and mrsi images were registered with ct ones using non-rigid registration technique. the ct based planning (bp), ct/mr...
در این پایان نامه، نحوه انتخاب مجموعه prf مناسب براساس الگوریتم ژنتیک در رادارهای پالس داپلر مورد بررسی قرار داده خواهد شد. در این راستا مدهای lprf، hprf و mprf در رادارهای پالس داپلر مطالعه می-شوند. از آنجایی که در رادارهای پالس داپلر در مد mprf نیاز به ارسال چندین دسته prf می باشد انتخاب مجموعه prf مناسب حائز اهمیت است. major-minor، m:n و الگوریتم ژنتیک روش هایی هستند که جهت بدست آوردن مجموعه...
BACKGROUND Patients eligible for cardiac resynchronisation therapy (CRT) have an indication for primary prophylactic implantable cardioverter defibrillator (ICD) therapy. However, response to CRT might influence processes involved in arrhythmogenesis and therefore change the necessity of ICD therapy in certain patients. METHOD In 202 CRT-defibrillator patients, the association between baselin...
