Background: The need for a rapid, noninvasive method for unwanted hair removal has led to the development of various light sources for this purpose. Objective: To evaluate the efficacy of Intense Pulsed Light source (IPLS) on unwanted hairs. Patients & Methods: In this open, uncontrolled clinical trial, 77 different anatomical areas in 34 referred patients to "Novin Didegan Clinic" in Tehran in 1380-1381, were treated by IPLS at fluencies ranging from 22 to 34 j/cm2 after their demographic data and the number of hairs were recorded. The 3 to 7 treatment sessions were accomplished 4 to 6 weeks apart. All of the patients were followed 6 months after the last therapy. The quantitative data were  analyzed by paired t test. Results: Six months after the last therapy, more than 50% reduction in number of hairs was noted in 80% of the treated areas; with mean reduction of 72±23 percent. Side effects were mild and reversible and occurred in ten patients. Conclusion: The IPLS appears to provide an effective and safe method for long term excess hair removal in various skin types.      

Distributing geographical information on the Internet is an enforcing factor for information providers. Internet allows all levels of society to access geographical information, and provides a media for processing geo-related information with no location restrictions. Web-based GIS is evolved from different Web maps and client-server architecture to distributed ones. As such, Internet reshapes all functions of information systems including: gathering, storing, retrieving, analyzing, and visualizing data. The high cost of GIS system, the release of system specific databases, and the enormous software developer efforts on upgrading the system are fading with the introduction of Web-based GIS Moreover, disseminating spatial information on the Internet improves the decision-making processes.This paper examines the current Web GIS technologies with emphasis on architectures. Eight state-of–the-art Web GIS products from leading GIS companies have been scientifically assessed. This paper also proposes a Web GIS development strategies starting from requirement analysis, and ending in GIS use and maintenance. Disseminating Iranian Road information on the Internet has been presented as a successful implementation of the strategy.It is concluded that the Internet based information delivery adds the margin of profitability of the Transportation and Terminal Organization. The proposed strategy has been tested successfully. Civilian can get to their destinations faster.

Accessibility to precise spatial and real time data plays a valuable role in the velocity and quality of flood relief operation and subsequently, scales the human and financial losses down. Flood real time data collection and processing, for instance, precise location and situation of flood victims may be a big challenge in Iran regarding the hardware facilities (such as high resolution aerial imagery devices) owned by the correspond organizations. To overcome the mentioned inabilities as well as reducing the financial costs for real time monitoring purpose of a flood, the current research intended to use the capacity of the flood victims and other volunteers to collect and upload real time data to rescue themselves…..

Background: The aim of this study is to explore the safety and diagnostic performance of dual-source CT scan in comparison with single source CT scan and conventional angiography in patients with coronary heart diseases.Materials and methods: A systematic review was performed using CRD standard methods. The Cochrane Library, MEDLINE, EMBASE, Google Scholar and TRIP were searched up to April 2009. The references of the marked studies and gray literature were also searched.Results: 17 articles were included. 9 articles reported the safety and 12 articles reported the diagnostic performance of DSCT.  Generally DSCT was a non-invasive and safe procedure.  Using DSCT the exposure of patient to X-ray was less than 64-slice single source CT (SSCT) and more than conventional angiography. For the DSCT the mean sensitivity was 90.4%, mean specificity was 82%, mean PPV was 83% and mean NPV was 96%. For the SSCT the mean sensitivity was 90.4%, mean specificity was 82%, mean PPV was 83% and mean NPV was 96%. The mean sensitivity, specificity, PPV and NPV of DSCT were slightly higher than SSCT.Conclusion: DSCT is a noninvasive and relatively safe technology. The diagnostic performance of DSCT is higher than SSCT, but its performance is not so much high to be able to substitute the conventional invasive angiography which is still the gold standard test.
