Assessment of safety in drinking water supply system of Birjand city using World Health Organization’s water safety plan

Background: The conventional method for managing drinking water quality is not a suitable preventive strategy for protecting public health. A water safety plan (WSP) presents a systematic approach to ensuring the health and quality of drinking water. This study assessed the drinking water supply system safety of Birjand city using the WHO’s WSP. Methods: This investigation employed the WSP-QA Tool and the WSP manual of the WHO and the AWI. For this purpose, software checklists were prepared and, after confirmation of content and face validity, completed based on Birjand’s water and wastewater company records and interview with company’s experts. Data was analyzed using WSP-QA Tool. Results: From total possible 440 points for full use of the program and 328 points of the studied phases, a score of 190 was acquired, indicating a 43.18% coordinated implementation with WSP. System description and management procedures showed the maximum and minimum percentages of congruency with the WSP of 87.5% and 25%, respectively. Among the components of the water supply system, water resource had the most attention. Conclusion: As regards the percentage of overall WSP-phase implementation and the low attention given to some key parameters of the water supply system, such as risk assessment and management procedures, the system currently enjoys a relatively medium level of safety. However, the high points of some phases such as system description, operational monitoring and verification enhance the system’s flexibility for changing the current approach of qualitative management to the WSP.

Collection, identification of Iranian fish parasites for “Iranian parasitology Museum”

Abstract: Identification and classification of aquatic parasites are more important by the day. Aquaculture development are faced with parasites previously "not pathogenic in normal conditions, but under certain conditions bacame diseases and have caused heavy losses to the aquaculture farms. The results of these studies recognize the importance of parasites in fish production has clear economic value. Before any action for economic aquatic breeding the parasites that can infect the fish have been identified and methods of control will be drawn. The current project is a part (the fishes) of the project Parasitology Museum in the Faculty of Veterinary medicine of Tehran University. In the first phase of the project, it was planned the fish parasites from different regions of the country were collected and the Iranian Fish Parasites Data Base has also set up. Required experts and various specialties were organized for implementation an recognation of the collected parasitese. The province executive and coordination necessary and the methods of sampling were discussed after a day of training workshop was held at the Faculty of Veterinary medicine of Tehran University. Due to the lack of funds needed to coordinate the implementation, it was conducted that the parasite specimens collected from other projects. In the first phase of projects 261 parasites various have been sent. Collected samples received a temporary code and announced. In the laboratory the specimens categoried and the shape designed and finally the consultants send the final identification of the parasites. Posted parasites according to the latest international standards are maintained. Each parasite has a unique code that represents the name of the sender, verification of the final consultant, host and fishing region. Simultaneously, reported fish parasites from 1327 AD (1949 AD) were collected to create a database, they classified to be placed on the site inPersian and English. Fish parasites that have been reported are available in four types: final report of the research projects conducted at research centers and universities, student theses, abstracts published in scientific conferences and finally "published in national and international research journals. “Iranian fish parasitesd database” included: Founders and Pioneers Monument, Iranian fish parasite fauna, History, Search, Resources, Executive Committee, links, News. Researchers can search through the five “key words”: the name of the parasite, the parasite class branch, region or provincial fishing, infected of host organ. After achieving the desired list of parasites, descriptions, and specifications can be observe. The resource section lists some of the articles published and will be visible as a “pdf”

Diagnostic value of silver nitrate staining for nucleolar organizer regions in selected head and neck tumors

Background: The present study is aimed to assess the usefulness of silver nitrate staining of nucleolar organizer regions (NORs) as a quantitative criterion for the diagnosis of selected head and neck tumors. Materials and Methods: The silver nitrate staining technique was used on 195 paraffin blocks collected from 85 patients. The samples consisted of 21 squamous cell carcinoma (SCC) of larynx, 28 SCC of oral mucosa and 36 samples of most common salivary gland tumors. Mann-Whitney U-Test was used for data analysis. Results: A significant difference was seen in the number of AgNOR dots between oral and laryngeal SCC with surrounding dysplastic and normal tissues ( P < 0.001) and also between mucoepidermoid carcinoma and adenoid cystic carcinoma with pleomorphic adenoma and normal salivary gland tissue ( P < 0.001). Conclusion: The silver nitrate staining for NORs is a useful method for aiding the diagnosis of malignant and dysplastic mucosal lesions and also malignant and benign salivary gland tumors

Effects of Endurance and Circuit Resistance Trainings on Lipid Profile, Heart Rate, and Hematological Parameters in Obese Male Students

Studies have shown that different exercise ways are of the most important factors that affect cardiovascular risk factors and hematological parameters. This present paper aims to study the effects of two methods of endurance and resistance training on lipid profiles, heart rate, and hematological parameters in obese male students. 36 obese students were purposefully selected and randomly divided into three groups of 12 including endurance exercise, resistance exercise, and control. Exercise program was performed 3 times a week for 8 weeks, with a specific duration and intensity in both endurance and resistance exercise groups. Blood sampling was done after 14 fasting before the trial and 48 hours after the last training session. Results showed that both resistance and endurance exercises significantly increased HDL-C, Hct, and Hb and significantly decreased TC, TG, and resting heart rate (P>0.05). Also, Resistance exercise significantly increased the PLT and decreased LDL-C (P>0.05). However, WBC and RBC showed no significant change in the resistance and endurance exercise groups (P>0.05). In addition, no significant difference was observed between endurance and resistance exercise (P>0.05). In general, both endurance and resistance exercises can affect the lipid profile and hematological parameters and also reduce the resting heart rate. Therefore, they can be considered as an appropriate and non-medication approaches to prevent and reduce the incidence of cardiovascular diseases and obesity-related disorders in obese male adolescents
