در این پژوهش سنتز آزمایشگاهی کربن فعال به روش فیزیکی در واکنش‌گاه چرخان با استفاده از گازهای اکسید کننده کربن دی اکسید و بخار آب از پوست سخت پسته به عنوان واکنشگر مورد بررسی قرار گرفت. اثر سه عامل دمای فعال‌سازی، زمان ماند و دبی گاز اکسید کننده بر روی عدد یدی و میزان سوختن مورد بررسی قرار گرفت. پس از تجزیه و تحلیل و بهینه‌سازی داده‌ها در فعال‌سازی با کربن دی اکسید، کربن فعالی با عدد یدی 1452/14...
Recent imaging studies have implicated the anterior cingulate cortex (ACC) in various cognitive functions, including attention. However, until now, there was no evidence for changes in neuronal activity of individual ACC neurons during performance of tasks that require attention and effortful thought. We hypothesized these neurons must exist in the human ACC. In this study, we present electroph...
The purpose of this study was to investigate the influence of electrical stimulation of anterior cingulate cortex (ACC) on spontaneous activity of neurons in thalamic ventrobasal nucleus (VB). Experiments were performed on 12 male Sprague-Dawley rats weighing 250-310 g (4-5 months old). According to Paxinos and Watson's coordinate atlas of the rat, the frontal and parietal cortical areas were e...
خلاصه سابقه و هدف: باکتری اشریشیاکلای خارج روده ای مهمترین عامل عفونت های ادراری-تناسلی در انسان است. چندین فاکتور حدت مثل ژن های کد کننده پروتئین های سیتوتوکسین، ادهسین، رسپتورهای سیدروفور و پروتئاز خارج غشائی در اشریشیاکلای های خارج روده ای انسان شناسایی شده است. این مطالعه به منظور بررسی میزان توزیع ژن های کد کننده فاکتور های حدت و ارتباط آن با گروه های فیلوژنتیکی در ایزوله های اشریشیاکل...
PURPOSE The purpose of the study was to evaluate the treatment results of adenoid cystic carcinoma (ACC) of the airway at a single institution during a 30-year period. MATERIALS AND METHODS All cases of ACC of the airway over a 30-year period at one tertiary care institution were reviewed retrospectively. The demographics, treatment modalities, pathologic characteristics, and outcomes were ev...
BACKGROUND Identifying novel tumor biomarkers to develop more effective diagnostic and therapeutic strategies for patients with ACC is urgently needed. The aim of the study was to compare the proteomic profiles between adrenocortical carcinomas (ACC) and normal adrenocortical tissues in order to identify novel potential biomarkers for ACC. METHODS The protein samples from 12 ACC tissues and t...
The DNA sequences of wheat Acc-1 and Acc-2 loci, encoding the plastid and cytosolic forms of the enzyme acetyl-CoA carboxylase, were analyzed with a view to understanding the evolution of these genes and the origin of the three genomes in modern hexaploid wheat. Acc-1 and Acc-2 loci from each of the wheats Triticum urartu (A genome), Aegilops tauschii (D genome), Triticum turgidum (AB genome), ...
The aim of the present study was: (1) to develop a new method for total energy expenditure (TEE) assessment, using accelerometry (ACC) and heart rate (HR) telemetry in combination; (2) to validate the new method against the criterion measure (DLW) and to compare with two of the most common methods, FLEX-HR and ACC alone. In the first part of the study VO(2), HR and ACC counts were measured in t...
We partially purified 1-aminocyclopropane-1-carboxylate (ACC) oxidase from senescing petals of carnation (Dianthus caryophyllus L. cv. Nora) flowers and investigated its general characteristics, and, in particular, the inhibition of its activity by ACC analogs. The enzyme had an optimum pH at 7-7.5 and required Fe2+, ascorbate and NaHCO3 for its maximal activity. The Km for ACC was calculated a...
