Coagulase gene polymorphism of Staphylococcus aureus isolated from clinical and sub-clinical bovine mastitis in Isfahan and Chaharmahal va Bakhtiari provinces of Iran

Mastitis is a common disease in dairy cattle and is an inflammatory response of the breast tissue to bacterial attack to this tissue. Mastitis causes considerable loss to the dairy industry, among the several bacterial pathogens that can cause mastitis; Staphylococcus aureus is probably the most lethal agent because it causes chronic and deep infection in the mammary glands that is extremely difficult to cure. Several virulence factors including coagulase gene are produced by S. aureus and may contribute to its pathogenicity. This study was conducted to investigate the coagulase gene polymorphism of S. aureus isolated from clinical and sub-clinical bovine mastitis milk samples in Isfahan and Chaharmahal va Bakhtiari provinces of Iran. Amplification of the coagulase gene from 86 S. aureus strains isolates by specific primers showed 31 specimens contained 970 bp fragment, and 11 strains contained 730 bp fragment relevant to coa gene (coagulase) in PCR. After enzymatic digestion with AluI, 31 specimens contained three bands: 320, 490, and 160 bp (genotype I) and 11 specimens contained two bands: 490 and 240 bp (genotype VIII) in the RFLP

System Dynamics Modeling of Multipurpose Reservoir Operation

System dynamics, a feedback – based object – oriented simulation approach, not only represents complex dynamic systemic systems in a realistic way but also allows the involvement of end users in model development to increase their confidence in modeling process. The increased speed of model development, the possibility of group model development, the effective communication of model results, and the trust developed in the model due to user participation are the main strengths of this approach. The ease of model modification in response to changes in the system and the ability to perform sensitivity analysis make this approach more attractive compared with systems analysis techniques for modeling water management systems. In this study, a system dynamics model was developed for the Zayandehrud basin in central Iran. This model contains river basin, dam reservoir, plains, irrigation systems, and groundwater. Current operation rule is conjunctive use of ground and surface water. Allocation factor for each irrigation system is computed based on the feedback from groundwater storage in its zone. Deficit water is extracted from groundwater.The results show that applying better rules can not only satisfy all demands such as Gawkhuni swamp environmental demand, but it can also  prevent groundwater level drawdown in future

Micropropagation of Juniper (Juniperus polycarpos): Optimizing surface sterilization pretreatments can play key role in suppression of contamination and browning of shoot tip explants

The juniper (Juniperus polycarpos) is enable to growth at the extremist of the geology, climatology and hydrology condition. The emptiness seed, embryo degeneration and seed dormancy are problems which necessitate the application of biotechnological technique to propagate mentioned juniper plant in vitro. Obtaining high efficiency of surface sterilization in order to prevent explants contamination and browning is necessary to success at initiate stage of juniper micropropagation. So, the effects of formulated of hypochlorite sodium, mercury chloride and ethanol as surface sterilization treatments on shoot tip explants of juniper were investigated. Optimized surface sterilization had a significantly effect on decrease contamination and browning in shoot tip explants (P<0.01). The results showed that surface sterilization treatments inhibited microbial or fungal contamination and browning of explants which can be minimized by optimizing mercuric chloride pretreatments. The formulated duration and concentration of hypochlorite sodium not only had no appreciable suppression effect on the contamination and browning in explants but also the browning extension in culture medium like same control was accelerated. It was found that mercuric chloride sterilization had distinguish or effective more than hypochlorite sodium on decrease contamination or browning. In contrast, lowest contamination or browning in culture medium and explants was displayed by formulated mercuric chloride. Therefore, the results suggested that in tissue plants if the aim is micropropagation of Juniperus polycarpos, elimination browning or having contaminated-free plants could be get in initiate state by using optimized mercuric chloride (Ethanol 70% at 1 min- sterile distilled water (SWD)- HgCl2 0.1% at 3 min-SDW) as surface sterilization

Investigate the frequency of virulence genes Vibrio parahaemolyticus isolated from fish, lobsters and crabs caught from Persian Gulf

Background and Aim: Annually, many reports of occurrence of food poisoning due to the consumption of sea-foods contaminated with Vibrio species have been published. The present study was carried out to study the prevalence rate of Vibrio parahaemolyticus and V. cholera and evaluation of presence of virulence genes of V. parahaemolyticus in sea-food products caught from Persian Gulf. Materials and Methods: In total, 200 samples of fish, lobster and crab caught from Persian Gulf collected in the summer of 2013 and were transferred to the food quality control laboratory of the Islamic Azad University of Shahrekord. Samples were cultured and the positive specimens were evaluated for presence of bacterial species and virulence genes using Polymerase Chain Reaction. Results: In total, 34.5% of samples were contaminated with Vibrio species. Frequency of V. cholera and V. parahaemolyticus were 5% and 21%, respectively. 8.5 percent of samples were contaminated with other species of Vibrio. From a total of 42 positive samples of V. parahaemolyticus, frequency of tdh, tlh and trh virulence genes were 45.93%, 40.47% and 16.46%, respectively. Conclusions: The sea-food products of Persian Gulf were infected with V. parahaemolyticus and V. cholera. Fish samples had the highest prevalence of V. parahaemolyticus and V. cholera. It seems that, places of fishing and processing and the moods of transportation and distribution of fish, lobster and crab don’t have suitable hygiene in Iran

Effects of Breastfeeding and Sensorial Saturation on Physiological Parameters of Infants after Administration of Pentavalent Vaccine at Four and Six Months of Age: A Field Trial

vaccination pain management in infants may prevent short-term and long-term physical and mental consequences in them. As a result, this study aimed to determine and investigate the effect of breastfeeding and sensorial saturation on physiological parameters of infants after administration of pentavalent vaccine at four and six months of age. Materials and Methods: This randomized controlled field trial was conducted on 171 four-month-old infants. The infants were randomized into three groups. The first group was breastfed for two minutes before vaccination (Breastfeeding group =55 infants). In the second group, the five senses of the infants were stimulated for two minutes before vaccination (Sensorial Saturation group =57 infants). The third group did not receive any intervention (Control group = 59 infants). In all groups, physiological parameters of the infants at four and six months of age were measured and recorded one minute after the vaccination. Data was analyzed using descriptive and inferential statistics in SPSS version 21.0 software. Results: Results showed no significant difference was observed in demographic variables of research samples including gender and weight at four and six months of age,and statistically significant between groups difference in three physiological parameters (respiratory rate, heart rate, and peripheral oxygen saturation) of the infants at four and six months of age (p=0.001). Although sensorial saturation was more effective than breastfeeding, this difference was not statistically significant; whereas, these interventions were significantly more effective than the control. Conclusion: Both breastfeeding and sensorial saturation practices resulted in the stability of physiological parameters of the infants after vaccination at four and six months of age; however, no significant within-group difference was observed after vaccination at four and six months of age in these two groupsand both methods had identical effects
