Recently deep submicron and SiGe (silicongermanium) bipolar CMOS technologies have enhanced the performance of Si-based radio frequency (RF) integrated circuits up to microwave frequencies. The integration of RF MEMS components, such as inductors and capacitors, could further improve the performance of key RF circuit blocks such as voltage controlled oscillators (VCO), low-noise amplifiers, fil...

Among various treatments, plants play a crucial role in cancer chemotherapy. Base on literature data, different species of the thymeleaeceae family have been found to be good sources for anticancer agents. Therefore, our laboratory has initiated a research project on evaluating the anticancer properties of the Iranian medical plant, Daphne mucronata (Thymeleaeceae). Gnidilatimonoein is a new di...

The number of cases with hepatocellular carcinoma (HCC) are on the increase. The aim of the present study was to investigate the clinical effect and relevant mechanism of combined sorafenib and radiofrequency ablation (RFA) in the treatment of the early small HCC. A total of 120 cases of patients with small HCC that presented during the period of May 2007 to June 2010 were selected and divided ...

Abstract. Random Forest (RF) is a powerful ensemble method for classification and regression tasks. It consists of decision trees set. Although, a single tree is well interpretable for human, the ensemble of trees is a black-box model. The popular technique to look inside the RF model is to visualize a RF proximity matrix obtained on data samples with Multidimensional Scaling (MDS) method. Here...

The main idea of this work is to design a notch filter structure with narrow width and maximum reflection while reducing fabrication challenges. In addition, using anti-reflection layers in the outermost part designed structure, pass-band ripples are reduced. study, we considered [(nHnL)s (mHmL)p (nHnL)z] n=5 m=3. Using form combining 3 5 quarter-wave coefficients instead 1 3, could reach narro...

The protective action of quercetin against the pro-oxidant and apoptotic effect of etoposide was investigated in HL-60 cells with a high level of myeloperoxidase (MPO) activity and in cells treated with MPO inhibitor, 4-aminobenzoic acid hydrazide (ABAH). Quercetin significantly protected MPO-rich cells against the pro-oxidative (p<0.05) and apoptotic (p<0.05) effects of etoposide. Pre-treatmen...

aim: identification of contributory factors in smoking and gaining insight into the roles played by each of these factors including health literacy (hl) may account for quitting or decreasing the prevalence of smoking. the aim of the current study was to identify the effects caused by different hl levels on smoking.methods: 347 students inhabiting the dormitories of shahid beheshti university o...

objective: titration of viruses is important to determine the quantity of virus in vaccine development, master virus seed stock preparation, viral vector studies and virus replication. in this study, we compared the ccid50% and plaque assay as a standard titration method for rotavirus (rf) and hsv-1.   methods: the ma104 and vero cells were inoculated by rf and hsv-1 in 6- and 96-well plates. f...
