background: the aim of the present study was to develop a scoring system for predicting 1-year major adverse cardiac events (mace), including mortality, target vessel or target lesion revascularization, coronary artery bypass graft surgery, and non-fatal myocardial infarction after percutaneous coronary intervention (pci). methods: the data were extracted from a single center pci registry. the ...
conclusions a majority of ovarian masses, especially those diagnosed within a short duration after hysterectomy, are benign. iranian patients with such ovarian masses when asymptomatic and associated with negative tumor markers could be followed up, and prophylactic oophorectomy may not be necessary. results of the 1052 patients with ovarian masses, 45patients (mean age, 53.11 ± 9.56 years) who...
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...

In a previous paper, it was shown that HE is a binary form with complex coefficients having degree n > 3 and discriminant Df ^ 0, and if Af is the area of the region \F(x, y)\ < 1 in the real affine plane, then \DF\llni-"-^AF < 1B{\, \), where B{\ , 1) denotes the Beta function with arguments of 1/3 . This inequality was derived by demonstrating that the sequence {M„} defined by Mn = max|Df \Ui...
The efficacy of fast synaptic inhibition is critically dependent on the accumulation of GABAA receptors at inhibitory synapses, a process that remains poorly understood. Here, we examined the dynamics of cell surface GABAA receptors using receptor subunits modified with N-terminal extracellular ecliptic pHluorin reporters. In hippocampal neurons, GABAA receptors incorporating pHluorin-tagged su...
The objective of this work was to estimate the antioxidant capacity of some fruits extracts containing anthocyanins (strawberry, raspberry, elderberry, mulberry, blackberry, bilberry, black and red currant) using an electrochemical technique and three classical chemical methods based on reaction between antioxidants and a chromogen compound. evaluation of antioxidant activities of extracts was ...
