این پژوهش در قالب پنج آزمایش در سال های 89 تا 91 به اجرا در آمد. آزمایش اول مطالعه تغییرات مختلف فیزیکوشیمیایی در گلبرگ های دو رقم میخک گلدانی ارقام پینک و استا طی 5 مرحله مختلف از نمو گل ها بود. در هر دو رقم مورد بررسی، بیشترین میزان اتیلن تولیدی، acc (آمینو سیکلو پروپان کربوکسیلیک اسید)، فعالیت آنزیم های آنتی اکسیدانی و کربوهیدارت های محلول، در مرحله باز شدن کامل گل ها (مرحله 5) بود. در بین ا...
abstracta pot study was conducted in order to evaluate the effect of plant growth promoting rhizobia (pgpr) on canola growth and ionic composition under salt stress conditions, was conducted as factorial in randomized complete block design with three replications. salinity in four levels of 0, 3, 6 &9 ds/m were evaluated with mixture of salts nacl & mgcl2. canola seeds were inoculated with sele...
Cognitive control includes the ability to formulate goals and plans of action and to follow these while facing distraction. Previous neuroimaging studies have shown that the presence of conflicting response alternatives in Stroop-like tasks increases activity in dorsal anterior cingulate cortex (ACC), suggesting that the ACC is involved in cognitive control. However, the exact nature of ACC fun...
AMP-activated protein kinase (AMPK) has previously been demonstrated to phosphorylate and inactivate skeletal muscle acetyl-CoA carboxylase (ACC), the enzyme responsible for synthesis of malonyl-CoA, an inhibitor of carnitine palmitoyltransferase 1 and fatty acid oxidation. Contraction-induced activation of AMPK with subsequent phosphorylation/inactivation of ACC has been postulated to be respo...
A pyridoxal 5'-phosphate (PLP)-dependent enzyme, 1-aminocyclopropane-1-carboxylic acid (ACC) synthase (S-adenosyl-L-Met methylthioadenosine-lyase, EC 4.4.1.14), catalyzes the conversion of S-adenosyl-L-methionine (AdoMet) to ACC. A tomato ACC synthase isozyme (LE-ACS2) with a deletion of 46 amino acids at the C terminus was chosen as the control enzyme for the study of the function of R286 in A...
Adenoid cystic carcinoma (ACC) is a relatively common head and neck tumor, however, is rare in the digestive tracts. There have been <100 cases of esophageal ACC reported to date and no cases of gastric ACC. The present study reports the exceptional case of a 53-year-old male with a primary ACC of the cardia. The patient underwent a radical total gastrectomy with D2 lymphadenectomy and Roux-en-...
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...
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...
