Ranjbar, Reza,Saberfar, Esmaiel,Shamsaie, Alireza,Ghasemian, Ehsan Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.4

Background: Human papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide and the association between HPV infection and genital cancers has been well established. This study concerned the possible role of HPV infection in colorectal carcinoma (CRC) in the Iranian population. Materials and Methods: We examined 80 tissues obtained from patients with colorectal cancer consisting of 58 colon cancer samples and 22 rectal cancer samples and 80 tissues from patients with unremarkable pathologic changes as matched controls by sex, study center and anatomical sites. HPV infection and genotypes were detected using nested PCR and sequencing methods, respectively. Results: HPV DNA was detected in 5/80 (6.25%) cases including 1 of 22 (4.54%) patients with rectum cancer and 4 of 58 (6.9%) patients with colon cancer and 1/80 (1.25%) of controls. Furthermore, HPV-18 was detected as the most frequent type and we found no significant correlation between prevalence of HPV infection and anatomical sub- sites. Conclusions: Although a causal relation between human papillomavirus and colorectal cancer was not found through this study, analysis of medical records pointed to a possible role for high- risk types of HPV in increasing the potential of aggressiveness in colorectal cancer. This study shows a particular frequency of HPV genotypes in patients with colorectal cancer in Iran. Since HPV vaccines are limited to a few types of virus, using cohort studies in different geographical zones to screen for patterns of HPV infection in different organs might increase the efficacy and optimization of the current vaccines.

Mohsen Ranjbar 세계문화관광학회 2008 Conference Proceedings Vol.9 No.0

Nowadays, cultural resources are regarded as one of tourism industry expansion resources which are founder of cultural tourism. Importance of cultural tourism is that in terms of nature, people belonging to different cultures of traditional religious groups and those who belong to advanced economic system are gathered leading to considerable effects. Cultural tourism provides opportunities for the people belonging to different cultures to understand each other's culture and find out each other's cultural aspects. Cultural tourism is able to help advance and stabilize intra civilization cultures. Large country of Iran has different cultural landscapes all resulting from thousands of civilization. Kashan Province has a lot of cultural varieties and aspects among central desert regions of Iran. Rose water extraction and plant juice production ceremonies, Rose water extraction Ghamsar ceremonies, Mashahd Ardehal carpet washers and unique carpet weaving in Joshghan and the entire region of Kashan are rooted in culture of this region which attracts thousands of people to the said special ceremonies. In the present article, the writer knows cultural tourism of Iran as a way of cultural expansion of the societies and cultural relations and international peace and tries to study its role in cultural unity and expansion of region by introducing cultural tourism charismas.

Amene Ranjbar,Vahid Mehrnoush,Fatemeh Darsareh,Ahmed Kotb,Ahmed Zakaria,Mitra Shekari,Malihe Shirzadfard Jahromi 대한폐경학회 2022 대한폐경학회지 Vol.28 No.3

The most common type of urinary incontinence in women is stress urinary incontinence (SUI) which negatively impacts several aspects of life. The newly introduced vaginal laser therapy is being considered for treating SUI. This systematic review aimed to evaluate the efficacy of vaginal laser therapy for stress urinary incontinence in menopausal women. We searched the following databases: MEDLINE (via PubMed), EMBASE, Cochrane Library databases, Web of Science, clinical trial registry platforms, and Google Scholar, using the MeSH terms and keywords [Urinary Incontinence, Stress] and [(lasers) OR laser]. In our systematic review, prospective randomized clinical studies on women diagnosed with SUI as per the International Continence Society’s diagnostic criteria were included. The Cochrane Risk-of-Bias assessment tool for randomized clinical trials was used to evaluate the quality of studies. A total of 256 relevant records in literature databases and registers and 25 in additional searches were found. Following a review of the titles, abstracts, and full texts, four studies involving 431 patients were included. Three studies used CO2-lasers, and one used Erbium: YAG-laser. The results of all four studies revealed the short-term improvement of SUI following both the Erbium: YAG-laser and CO2-laser therapy. SUI treatment with CO2-laser and Erbium: YAG-laser therapy is a quick, intuitive, well-tolerated procedure that successfully improves incontinence-related symptoms. The long-term impact of such interventions has not been well established as most trials focused on the short-term effects.

Shiva Ranjbar,Asghar Ramezanian,Majid Rahemi 한국원예학회 2020 Horticulture, Environment, and Biotechnology Vol.61 No.1

This study evaluated the effects of preharvest nano-calcium fertilization on quantitative and qualitative characteristics of apple (Malus domestica Borkh. ‘Red Delicious’) fruit. From 70 days after full bloom to 30 days before commercial maturity, calcium chloride (0, 1.5, and 2.0%) and nano-calcium (0, 1.5, and 2.0%) solutions were sprayed on apple trees. This was performed five times during the growing season at 2-week intervals. Fruit weight, density, length (L), diameter (D), and L/D were evaluated at harvest. Additionally, several quality characteristics were measured: fruit firmness, total soluble solids (TSS), titratable acidity (TA), total phenolic content (TPC), total antioxidant activity (TAA), total anthocyanins content, starch content, fiber content, total sugars, and calcium content. The effects of nano-calcium treatment on fruit quality and quantity were more significant than that of conventional calcium chloride. The greatest improvements were obtained using 2.0% nano-calcium. TA, TPC, TAA, fiber, and starch content were significantly increased under the nano-calcium treatment. Compared to the control, TSS, total sugars, and anthocyanin content decreased under the calcium chloride and nano- calcium treatment. Our results support the use of nano-calcium as a promising fertilizer for improving the overall characteristics of apple fruit.

Mohsen Ranjbar,Rahim Sarvar 세계문화관광학회 2010 Conference Proceedings Vol.11 No.0

Silk road which is formed by the complete connection road networks by making its way through Eurasia over the centuries has been seeking regulatory functions and various political, social, cultural, artistic, religious and commercial and…..Silk road route as a historical complex phenomenon has been included in almost all factors to preserve the human race. For thousands of years Silk Road has not only opened a brilliant page in global history, but has a deep effect and an active functional role in expanding relations between counties in the future. This road which has had a long experience and has been linking people, demonstrates that humans have never confined themselves in their racial fences, ethnicity and geographical locations and have endured long hard roads. This road has been the passage way for cultures, different dialects, nationalities, cultures that have had a long history on earth. Countries located in the route of silk- road, create a main cultural intersection that the richest and most extensive heritages are located. These live and historical heritages have created tourism main attractions. Reviewing connecting old patterns in Silk Road and rebuilding its historical fiber, not only guarantees its preservation and maintenance, but ensures the survival of areas traditions and prospers tourism and placed in this path will be as a symbol and enigma. Silk-road in Iran is entered as an eastern-western axis to khorasan and from that route arrive at Toos, Neishabour, sabzavar, shah rood, damghan, semnan to ray and from ray which was a big city go to ghazvin and from there was divided into two branches. From ghazvin one way to the northwest meaning to sarab, Tabriz, marand and then khoy and then departed Iran and from the other to the west meaning to Hegmataneh (Hamadan today) then to Kermanshah and then depart Iran. Today revival and rejuvenation of Silk Road only historical commemoration is left and along this road could be very interesting to tourists. Other important points that we should now is that Iran is the only country that the terrestrial and marine silk road meet at the Persian Gulf. In this article it has been tried to in addition to identifying the strengths of this important historical cultural road, solutions for its revival for the purpose of regenerating the tourism markets have been presented.

Objectives: Gastrointestinal tract infection is still one of the serious public health problems in many geographic areas and is endemic in most countries including Iran. Early detection of the gastrointestinal tract pathogens can be extremely important. The aim of the current study was to apply a shortened time-multiplex polymerase chain reaction (PCR) for rapid and simultaneous detection of Salmonella spp., Shigella spp., and Vibrio cholera. Methods: The standard and clinical strains of Salmonella spp., Shigella spp., and V. cholerae were used in the assay. Multiplex PCR was performed and optimized based on amplification of invA, putative integrase, and ompW genes for detecting Salmonella spp., Shigella spp., and V. cholerae, respectively. The specificity of the assay was evaluated by testing 12 different bacterial species. Results: Only Salmonella spp., Shigella spp., and V. cholerae strains had positive results when subjected to the assay using multiplex PCR. The assay showed a high sensitivity, and no amplification products were observed in multiplex PCR with any of the other microorganisms. Conclusion: Our study indicated that the invA, putative integrase, and ompWbased multiplex PCR assay appears to be an efficient method for rapid and simultaneous detection of Salmonella spp., Shigella spp., and V. cholerae.

Babak Ranjbar,Gholam Dashti,Ali Omidvar,Javad Mahmoodi,Hasan Karbasi 보안공학연구지원센터 2014 International Journal of Hybrid Information Techno Vol.7 No.6

Cognitive method is used in this research to create portfilo of movement robot manipulator. Gradient descent (GD) fuzzy controller was used and robot’s postures and trajectory were expected in MATLAB/SIMULINK environment. Fuzzy logic controller (FLC) is an influential nonlinear controller to certain and uncertain systems which it is based on artificial intelligent and computes the required torques using the nonlinear feedback control law. Practically a large amount of systems have uncertainties accordingly this method has a challenge. Linear proportional-integral-derivative (PID) controller is a significant combination nonlinear stable-robust controller under condition of partly uncertain dynamic parameters of system. This technique is used to control of highly nonlinear systems especially in nonlinear time varient nonlinear dynamic system. To compensate for the dependence on model-free parameters, PID methodology is used. The nonlinear model dynamic formulation problem in uncertain system can be solved by using PID theorem. Proportional-Derivative-Integral (PID) theory is used to estimate the system dynamic.
