Conventional Vs. reverse nerve grafting for peripheral nerve repair in lower extremity of rats
Akbari H,Fatemi MJ,Shakour Z,Mousavi SJ
Tehran University Medical Journal , 2013,
Abstract: Background: Autograft is the best option in nerve defects when end-to-end repair can not sufficiently preserve nerve continuity. Theoretically, if the severed nerve is reversely grafted, it may prevent axonal growth into nerve branches, and larger amounts of axons will reach the target organ and more satisfactory results will be obtained. In this study we aimed to compare conventional versus reverse nerve grafting.Methods: This study was performed in Animal laboratory of Hazrat Fatemeh Hospital from April till August 2011. We randomly divided 40 Wistar rats into two groups. We excised 1.5 cm of the right sciatic nerve and anastomosed it conventionally between the proximal and distal ends of the nerve in rats in group A and in a reverse manner in rats in group B. The rats’ footprints were recorded in the first and 16th weeks after surgery. In week 16, the grafted nerves were removed under anesthesia for pathological examination and axon count. Subsequently, the results were compared clinically by sciatic functional index (SFI) through footprint analysis and paraclinically by axon count. A p-value smaller than 0.05 was considered statistically significant.Results: Conventional and reverse nerve grafting no had statistically significant differences in clinical assessment in the first and 16th weeks (P=0.87) post-surgically and also no difference in paraclinical assessment in week 16 (P=0.68). Conclusion: We had no significant clinically or para clinically differences between two approaches. It should be considered that the diameter and length of nerves and muscles in human is larger than rats, so the results of nerve repair may differ in human. We suggest a study in animal model which is anatomically more similar to human.

Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.27114
Abstract: Life on the earth is dependent on dynamic interactions between its physical, chemical and biological components. In fact, all the individual processes are responsible for regulating the environmental equilibrium which can provide biosphere for multiple forms of human life. In order to overcome on shortcomings, the use of immobilized cell bioreactor technology which provides a valuable effective for treatment of waste water is discussed. An immobilized system which in this matter is applied is about absorbed or captured microorganisms in a solid substratum to retain them in a reactor or analytical system. The multiply of these immobilized cells is done when by nutrients be supplied and then migrate to the surfaces which are referred to biofilms. The biofilms can be developed on various support systems such as polypropylene pall, rocks, sands, charcoal, ceramics, and glass beads. The controllable reaction vessels which are used for these colonized surfaces are referred to bioreactors. Bioreactors in both up flows and down flows mode which use of either batch or continuous processes principle can be operated. Synchronic with development in biotechnology, there is also an extensive development in the field of bioreactors like: pumped tower loop reactor (PTLR), liquid impelled loop reactor (LILR), multipurpose tower bioreactor (MTB), fluidized-bed and packed-bed bioreactor, that in this article are discussed them.
The Show-Up Identification Procedure: A Literature Review  [PDF]
Mattias Per Sj?berg
Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.41012
Abstract: A show-up is an identification procedure that only presents the witness with one suspect in contrast to a lineup where the suspect is presented among a number of fillers (i.e., known innocent people). This feature makes the show-up procedure very suggestive. In this literature review, an overview of the current research about this identification procedure is presented. The different factors that influence the accuracy in show-up procedures are separated into system (e.g., clothing bias, instruction bias, and the impact of multiple show-ups) and estimator variables (e.g., age, cross-race effects, and alcohol) in line with Wells [1]. The implications of the research are discussed together with suggestions for future research.

Reza Khani Jazani, Sajad Mousavi
Open Journal of Safety Science and Technology (OJSST) , 2014, DOI: 10.4236/ojsst.2014.41003
Abstract: In recent times, the relationship between quality and ergonomics discipline is a challenging topic. Although there are similarities and differences between these two areas, it is not so easy to describe the connection between these two issues. In this study by surveying several articles, different areas of ergonomics are divided into five categories including hardware ergonomics, environmental ergonomics, software ergonomics, work design ergonomics and macro ergonomics, then the impact on the quality of each of these areas will be discussed. Finally, the article concludes that, to reach an acceptable quality considering the ergonomic principles is an integral component of the organization policy.
The ethics of aesthetic surgery
Mousavi S
Journal of Cutaneous and Aesthetic Surgery , 2010,
Abstract: Advances in plastic and reconstructive surgery have revolutionized the management of patients suffering from disfiguring congenital abnormalities, burns and skin cancers. The demand for aesthetic surgery has increased in recent years, as our culture has become more concerned with image and appearance. Several ethical considerations such as patient′s right for informed counseling, beneficience and maleficience need to be given careful consideration.
Non-wood forest products, the utilization, and harvesting methods in Sardasht, North West Iran

International Journal of Forest, Soil and Erosion , 2012,
Abstract: Non-wood forest products include all kind of services which forest offers except woody production. People were using the forest resources over many centuries to fulfill the daily needs. However, only in the last decades non-wood forest products have gained more attention in world trade. Sardasht region in the northwestern Iran with a considerable forest cover was chosen as a study area. In order to carry out the study, questionnaires were prepaid and distributed among local people, and the results were analyzed. All kind of non-wood production which could be exchanged for money were listed, and other kind of non-market services such as protection of soil resources and recreation were not evaluated. Different forest by-products were recognized in the area including acorn, foliage leaves, galls, turpentine, pistachio (Pistacia vera) nuts, leaves and fruits of roses, cherry elaeagnus (Elaeagnus edulis), hawthorn (Ceratagus spp), wild plum (Prunus spp.), bitter almond (Amygdalus communis), walnuts (Juglans spp.), manna of Oak trees, wild pear (Pyrus spp.), sumac (Rhus coriaria). Among all these products, turpentine is the only non-wood forest product which can be export to neighboring countries. Other non-wood forest production has not widely spread in the market being consumed at local scale for household needs by local people. However, the non-wood products play an important role fulfilling the peoples’ needs through both non-market and market means. It is possible to improve the role of non-wood forest products in the daily life of local people with provoding facilities such as better transportation system and marketing.
The Study of the Therapeutic Effects of CpG Oligonucleotides in Murine Model of Allergic Asthma
T Mousavi
Qom University of Medical Sciences Journal , 2012,
Abstract: Background and objectives Augmentation of Th2 mediated responses such as elevation of serum IgE is the characteristic feature in atopy and asthma. CpG oligonucleotides (CpG ODN) have been used during the recent two decades as the potent immunomodulatory agents in allergic conditions. In this paper, we aim to report the anti-inflammatory effects of CPG ODN in murine model of asthma. Methods In this study, BALB/c mice were sensitized with ch.a. allergen and then treated intranasally with CpG ODN. Following the challenge with allergen inhalation, mice were sacrificed and their splenocytes were cultured in the presence of antigen. After three days of culture, supernatants were examined for IFN-γ levels by ELISA method, as an indication of Th1 response, and the results were compared with those in control mice without CpG therapy. Results The results indicate that the mice in the test group, which received CpG ODN, showed higher levels of systemic INF-γ, and lower levels of serum IgE compared with either the antigen or CpG negative ODN-treated groups. Conclusion Based on the results of this study, which shows higher INF-γ levels in mice received CpG ODN, it can be concluded that CpG motifs have immune response modulation potential apparently through the deviation of Th2 into Th1 responses, which lead to a decrease in IgE antibody level. Accordingly, we suggest that these components can have therapeutic effects in the asthma caused by ch.a. allergen.

Abstract: Background and Objective Nowadays Laparoscopic Cholecystectomy is known as a gold standard method for Cholecystectomy. This study was done to evaluate outcomes of the surgery in the first admitted group of patients in Qom Golpaegani hospital. Methods All patients that had been treated by Laparoscopic Cholecystectomy during 2005-7 were included in this retrospective survey. Study population was consisting of 305 cases with age between 15 to 86 years old, %64.9 women and 35/1% men and 80% with symptomatic gallstones. Data were collected using questionnaire and then analyzed using SPSS software. Results In 2007 multiplicity of Laparoscopic Cholecystectomy was the highest. The mean operation time was 45 min and duration of hospitalization was 12-48 hours. %80 of all cases (both men and women) had symptomatic gallstones which had been determined by sonography and others had acalculous Cholecystitis. The most common complication during operation was bradychardia as a result of gas flow into the abdomen. There was no case of death. Conclusion Our results showed that Laparoscopic Cholecystectomy is a standard method of Cholecystectomy and have a desirable outcome.
Causality in the Semantics of Esterel: Revisited
MohammadReza Mousavi
Electronic Proceedings in Theoretical Computer Science , 2010, DOI: 10.4204/eptcs.18.3
Abstract: We re-examine the challenges concerning causality in the semantics of Esterel and show that they pertain to the known issues in the semantics of Structured Operational Semantics with negative premises. We show that the solutions offered for the semantics of SOS also provide answers to the semantic challenges of Esterel and that they satisfy the intuitive requirements set by the language designers.
