引用

World Journal of Gastroenterology 2009年第25期15卷 3073-3085页

作者： Shirin Hasani-Ranjbar neda Nayebi Bagher Larijani Mohammad Abdollahi Endocrinology and Metabolism Research Center and Faculty of MedicineTehran University of Medical Sciences Faculty of Pharmacy and Pharmaceutical Sciences Research CentreTehran University of Medical Sciences

This review focuses on the efficacy and safety of effective herbal medicines in the management of obesity in humans and animals. PubMed, Scopus, Google Scholar, Web of Science, and IranMedex databases were searched up to December 30, 2008. The search terms were ＂obesity＂ and （＇herbal medicine＂ or ＂plant＂, ＂plant medicinal＂ or ＂medicine traditional＂） without narrowing or limiting search elements. All of the human and animal studies on the effects of herbs with the key outcome of change in anthropometric measures such as body weight and waist-hip circumference, body fat, amount of food intake, and appetite were included. In vitro studies, reviews, and letters to editors were excluded. Of the publications identified in the initial database, 915 results were identified and reviewed, and a total of 77 studies were included （19 human and 58 animal studies）. Studies with Cissus quadrangularis （CQ）, Sambucus nigra, Asparagus officinalis, Garcinia atroviridis, ephedra and caffeine, Slimax （extract of several plants including Zingiber officinale and Bofutsushosan） showed a significant decrease in body weight. In 41 animal studies, significant weight loss or inhibition of weight gain was found. No significant adverse effects or mortality were observed except in studies with supplements containing ephedra, caffeine and Bofutsushosan. In conclusion, compounds containing ephedra, CQr ginseng, bitter melon, and zingiber were found to be effective in the management of obesity. Attention to these natural compounds would open a new approach for novel therapeutic and more effective agents.

作者： Jafar Soltani Bahman Poorabbas neda Miri Jalal Mardaneh Department of Pediatrics Faculty of Medicine Kurdistan University of Medical Sciences Alborzi Clinical Microbiology Research Center Nemazee Hospital Shiraz University of Medical Sciences Besat Tertiary Hospital Kurdistan University of Medical Sciences

AIM: To study the antibiotic susceptibility patterns of gram-negative healthcare associated bacterial infections at two tertiary hospitals in the Sanandaj city, Kurdistan Province, ***: From January 2012 to December 2012, all positive cultures from potentially sterile body fluids were gathered. They sent to professor Alborzi clinical microbiology center in Shiraz for further analysis and susceptibility testing. The antibiotic susceptibility was determined using the Kirby-Bauer method(disk diffusiontechnique). The Results were interpreted according to Clinical and Laboratory Standards Institute guidelines against a series of antimicrobials. World Health Organization definitions for Healthcare associated infections were ***: Seven hundred and thirty-two positive cultures were reported from both hospitals. Seventynine isolates/patients fulfilled the study criteria for healthcare associated gram-negative infections. The most frequent bacterial cultures were from the pediatric wards(52%). Serratia marcescens(S. marcescens)(38%) Escherichia coli(E. coli)(19%), Klebsiella pneumoniae(K. pneumoniae)(19%), Acinetobacter baumannii(6%), Enterobacter species(6%), Serratia odorifera(4%) and Pseudomonas species(5%) were the most frequently isolated organisms. The susceptibility pattern of common isolates i.e., S. marcescens, E. coli and K. pneumoniae for commonly used antibiotics were as follows: Ampicillin 3.3%, 6.7%, 20%; gentamicin 73.3%, 73.3%, 46.7%; ceftazidim 80%, 73.3%, 33.3%; cefepim 80%, 86.7%, 46.7%; piperacillin/tazobactam 90%, 66.7%, 86.7%; ciprofloxacin 100%, 73.3%, 86.7%; imipenem 100%, 100%, 100%, respectively. CONCLUSION: The most effective antibiotics against gram-negative healthcare associated infections are imipenem followed by ciprofloxacin. The resistance rate is high against ampicillin and cephalothin. The high mortality rate(46.1%) associated with S. marcescens is alarming.

Forest Ecosystems 2016年第1期3卷 26-36页

作者： neda Amiri Seyed F.Emadian Asghar Fallah Kamran Adeli Hamid Amirnejad department of forestry sari agricultural and natural resource universitySariIran department of forest sciences gorgan agricultural and natural resource universityGorganlran department of forestry college of natural resourcessari agricultural sciences and natural resources universitySariIran department of forestry faculty of agriculturaluniversity of lorestanlorestanIran department of agricultural economics sari agricultural and natural resource universitySariIran

Background： Around 2000 plant species occur naturally in Lorestan Province of which 250 species are medicinal and myrtle is one of them. Myrtle is a shrub whose leaves and fruits have medicinal value and thus, if managed and harvested properly, could produce sustained economic benefits. In recent years, however, over half of the myrtle site areas was destroyed, due to inappropriate management and excessive harvesting practices. Thus, coming up with a practical harvesting approach along with identifying those factors damaging the sites, seems to be very crucial. Methods： In our investigation, we calculated the conservation value per hectare of myrtle in the Dooreh forest area in Lorestan Province. Using the Contingent Valuation （CV） and Double Bounded Dichotomous Choice （DBDC） methods, we determined the willingness to pay （VVTP） for myrtle conservation. The VVTP was estimated with a Iogit model for which indices were obtained based on a maximum precision criterion. Results： The results showed that 86.67 per cent of people were willing to pay for the conservation of these myrtle sites. Average monthly WTP per family was calculated as $0.79. The annual conservation value in terms of WTP for the preservation of the myrtle sites in Dooreh was estimated as $102,525. Among the variables of the model presented, education had a positive impact, while the amount proposed for payment and family size had a negative impact on the WTP. Conclusions： Our estimate of the value of myrtle conservation should provide justification for policy makers and decision making bodies of natural resources to implement policies in order to conserve the natural sites of this species more effectively.

A Framework for Assessment of Water Poverty in Iran

引用

Chinese Journal of Urban and Environmental Studies 2023年第4期11卷 72-99页

作者： Maryam SERESHTI Mojtaba VALIBEIGI neda SAFARI Department of Urban Planning Guilan University Department of Architecture and Urban Planning Buein Zahra Technical University Department of Geography Planning and Environment

The water shortage crisis is one of the main concerns that is threatening the biological security in Iran. According to available data and information, providing a framework for the assessment of water poverty in Iran seems crucial. The land-dividing unit in Iran is the province, and most of the governmental information is gathered based on this unit. In this sense, Isfahan province, which is one of the central provinces in Iran that is suffering from water crises, has been selected. The water poverty index(WPI), which is adopted in accordance with Iran's situation, including five components of resources, access, capacity, use, and environment, has been used for each of Isfahan's cities. “Capacity” and “use” has the greatest correlation, and it seems any advancement in water utilization for economic purposes might result in increased capacity, and vice versa. Also,there is a positive correlation between WPI and components of access, capacity, use, and environment. It can be interpreted that the lack of access to water services may be due to a lack of income or education. Finally, access, capacity, and use showed the strongest relationships between WPI and its subcategories. Therefore, these three elements should be the main focus of any initiative to manage the water poverty in Isfahan province.
