Cytotoxic effect of <em>Cousinia verbascifolia</em> Bunge against OVCAR-3 and HT-29 cancer cells

Introduction: Little information is available about phytochemical and biological properties of Cousinia genus. In a primary study, seven Cousinia species including C. verbascifolia showed cytotoxic activity ranged between 18.4 &plusmn; 0.59 to 87.9 &plusmn; 0.58 &mu;g/mL. To the best of our knowledge, no other biological studies have been conducted on this plant. Therefore, in this study the cytotoxic effect of Cousinia verbascifolia Bunge against OVCAR-3 and HT-29 cancer cells was evaluated. Methods: Filtration and in vacuo concentration of methanol extract resulted in a green gum which was subjected on reverse column chromatography. Semi polar fraction (41.3 g) eluted with water: methanol (20:80), was then subjected on a silica gel column chromatography using hexane/acetone and resulted in 11 fractions. Finally, cytotoxic activities against ovarian and colon cancer cells were determined at a wavelength of 570 nm by Matrix metalloproteinase protein (MTT) standard method. Results: None of the fractions showed highly cytotoxic activity. Based on NCI, fractions Fr. 1, Fr. 2, Fr. 4, Fr. 5, Fr. 6, Fr. 8 and Fr. 10 showed moderately cytotoxicity with IC50 values ranged between 119 to 190 &mu;g/mL against OVCAR-3 cells. Fractions Fr. 1, Fr. 2, Fr. 6, Fr. 7 and Fr. 8 showed moderately cytotoxic activity ranged between 118 to 194 &mu;g/mL against HT-29 cells. Fr. 10 and Fr. 11 showed no cytotoxic activity. Conclusion: Due to the inhibitory properties of extract and its fractions on cancer cells, identification of responsible compounds possessing cytotoxic effects for generating possible new approach in medicinal chemistry are recommended.</p

Power Analysis of Sub-threshold Logics for Security Applications

Requirements of ultra-low power for many portable devices have drawn increased attention to digital sub-threshold logic design. Major reductions in power consumption and frequency of operation degradation due to the exponential decrease of the drain current in the sub-threshold region has made this logic an excellent choice, particularly for ultra-low power applications where performance is not the primary concern. Examples include RFID, wireless sensor networks and biomedical implantable devices. Along with energy consumption, security is another compelling requirement for these applications. Power analysis attacks, such as Correlation Power Analysis (CPA), are a powerful type of side channel attacks that are capable of performing a non-invasive attack with minimum equipment. As such, they present a serious threat to devices with secret information inside. This research analyzes sub-threshold logics from a previously unexplored perspective, side channel information leakage. Various transistor level and RTL circuits are implemented in the sub-threshold region as well as in the strong inversion region (normally the standard region of operation) using a 65 nm process. Measures, such as Difference of Mean Energies (DME), Normalized Energy Deviation (NED) and Normalized Standard Deviation (NSD) are employed to evaluate the implemented architectures. A CPA attack is also performed on more complex designs and the obtained correlation coefficients are used to compare sub-threshold and strong inversion logics. This research demonstrates that sub-threshold does not only increase the security against side channel attacks, but can also decrease the amount of leaked information. This research also shows that a circuit operating at sub-threshold consumes considerably less energy than the same circuit operating in strong inversion and the level of its instantaneous power consumption is significantly lower. Therefore, the noise power required to cover the secret information decreases and the attack may be dramatically more difficult due to major increase in the number of required power traces and run time. Thus, this research is important for identifying sub-threshold as a future viable technology for secure embedded applications

QUALITY OF SERVICES IN REHABILITATION CENTERS FROM THE PATIENTS' PERSPECTIVE, USING THE IMPORTANCE-PERFORMANCE ANALYSIS IN AHVAZ, 2015

Quality of service is a key factor in the success of health care organizations, including the rehabilitation centers. Nowadays, rehabilitation centers are faced with many challenges in the quality of service and there are many differences between patients' expectations and perceptions of the service quality received at these centers. So, this study aimed to determine the quality of services in rehabilitation centers from the patients' perspective in Ahvaz using the importance - performance analysis (IPA). In this analytical-descriptive study, the study population was all patients who referred to the five selected rehabilitation centers in Ahvaz in 2015. In this study, 110 patients were selected as samples by a random sampling method. Using a standard 22- item SERVQUAL questionnaire, the quality of service provided in the centers in 5 dimensions of two parts "importance" and "performance was investigated. Data were analyzed using the SPSS and Excel software. All dimensions of service quality in the centers studied, were in the first area of the importance- performance matrix, namely at optimal levels. A significant difference was seen between scores of the importance and performance of the dimensions of the quality of service at the centers studied (p=0. 001). The highest (-0.75) and the lowest (-0.49) gap was estimated for the dimensions of "tangibility" and "empathy", respectively. Services offered in any of the dimensions were not beyond the expectations of clients and still there is much possibility for improving the process. Keywords: Quality of service; Importance-Performance Analysis (IPA); Rehabilitation center
