statement of problem: periodontal disease (pd) has been linked to adverse cardiovascular events by unknown mechanisms. c-reactive protein (crp) is a prognostic marker for cardiovascular disease, with reported elevated serum levels during pd. purpose: the aim of the present study was to evaluate the association between pd and higher crp levels in the serum of acute myocardial infarction (ami) pa...
چکیده: کمپلکس های ارتو فلز دار شده ی [pd(c6h4ch2nrr)xy](r, r=h, me, et, t-bu. x=cl, br. y=pph3, 4-picoline, sym-collidine) از واکنش pd(oac)2 و آمین های [c6h5ch2nrr`](r, r`=h, me, et, t-bu) همراه با رفلاکس در بنزن و متانول و سپس اضافه کردن نمک nax(x=cl, br) بدست آمده اند. از واکنش این کمپلکس های دو هسته ای سنتز شده با نوکلئوفیل های 4-picoline, sym-collidine, pph3 کمپلکس های مونومری، سیکلو پال...
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 w...
Parkinson’s disease (PD) is a neurodegenerative disorder that does not develop spontaneously in some animal species. PD can be induced experimentally in some laboratory animals including mouse, rat and horse. Globus pallidus (GP) and substantia nigra pars compacta (SNc) are damaged in patients with PD. The hallmark of PD is a progressive impaired control of movement, an alteration of autonomic ...
This paper focused on a novel method of electroless plating ruthenium (Ru) on solid or porous substrates like porous stainless steel (PSS) discs or ceramic tubes. A novel complexing plating bath of Ru was developed. It is proven that Ru can be deposited directly on these substrates by the bath at a temperature of 328 K and strong alkaline environment. TGA, SEM, EDX and XRD confirmed the success...
Purpose: Walking pattern in patients with Parkinson's disease (PD) is abnormal, and dynamic balance of these patients is not clear yet. The objective of this study was to analyze the dynamic balance of patients with PD during walking and comparing it with normal elderly individuals. Methods: This is an Ex-post - facto research study design. Twelve male patients with PD (mean age: 64.0&...
Background: Peritoneal dialysis (PD) is an efficient alternative for hemodialysis. Removal of waste metabolites and excess water from the blood circulation are the two main tasks done during dialysis. These are done by using a filter; in PD, the naturally semi-permeable peritoneal membrane acts as the filter. Automated PD machines control intelligently the operations to enhance the efficiency a...
Introduction: Parkinson Disease (PD), the second most common chronic neurodegenerative disorder, is characterized by tremor, bradykinesia, rigidity, and postural instability. SHANK3 (SH3 and multiple ankyrin repeat domain 3) belongs to the extremely conserved ProSAP/ Shank family of synaptic scaffolding proteins. Meanwhile, rs9616915 is a non-synonymous SNP (T>C) located in the exon 6 of the SH...
برای جداسازی هیدروژن از مخلوط های گازی غشاءجدید Pd-SiO2/PSS/NaX با استفاده از نانو زئولیت سدیم، NaX و بر پایه فولاد متخلخل، PSS طراحی و ساخته شد. در ابتدا نانو زئولیت سدیم به روش هیدروترمال سنتز و با استفاده از خلاء بر روی سطح فولاد متخلخل نشانده شد و در گام بعدی کاتالیست Pd-SiO2 سنتز و به روش سل-ژل بر روی پایه PSS/NaX رسوب داده شد. در نهایت کاربرد مجموعه Pd-SiO2/PSS/NaX برای تصفیه هیدروژن مورد...
