The role of manufacturing on Iran's economic growth: Divisa’s Logarithmic Index Method

This article discusses the role of manufacturing in the economic growth of Iran using the logarithmic mean Divisia index (LMDI) method. The study identifies various drivers of industrialization and their impact on growth, including structural changes (productivity of labor and employment share in industrial factories) and employment scale. The LMDI method is used to analyze with a dataset from Iranian provinces between 1381 and 1399. The results show that industrialization has a positive and significant effect on economic growth, with structural changes having a greater impact than employment scale. The study highlights the importance of sustainable industrial development for economic growth in Iran

Candidemia in Febrile Neutropenic Patients; a Brief Report

Introduction: Febrile neutropenic patients are at risk of serious infections. The aim of the present study is to identify the frequency, species, and susceptibility patterns of candidemia in febrile neutropenic patients. Methods: This cross-sectional study was conducted on febrile neutropenic patients suspected with candidemia who had been referred to 3 educational hospitals during 9 months. Results: The blood samples of 80 febrile neutropenic patients with the mean age of 48§16.6 years were studied (60% female). Five (6.25%) episodes of candidemia were identified. The underlying disease was acute myeloid leukemia in 4 (80%) cases and all 5(100%) cases had central venous catheter and were receiving prophylactic ciprofloxacin and acyclovir. 100% of isolates were found to be susceptible to Voriconazole, 80% to Caspofungin, 60% to Amphotericin B, and 40% to Fluconazole. Conclusion: The frequency of candidemia among the studied febrile neutropenia patients was 6.25%, with 80% mortality rate, and themost frequently identified yeastwas Candida albicans (100% susceptible to Voriconazole)

Survey of Expression of Aflatoxin Production Regulator Gene (aflR) in Aspergillus Parasiticus by Alpinia Galanga L and Dorema Aucheri

Background: Aflatoxins are one of the highly toxic secondary metabolites, which are mainly produced by Aspergillus parasiticus. This species frequently cause of food and agricultural products contamination including cereals, peanuts, and crops in the field. During recent years, researchers have considered research on elimination of aflatoxin and antifungal effects of medicinal herbals, such as Alpinia galanga L and Dorema aucheri. In this study, the effect of A.galanga L and D.aucheri a natural compound was examined on Aspergillus parasiticus growth, aflatoxins production and the aflR gene expression.Materials and Methods: Antifungal susceptibility A.galanga L and D.aucheri was performed according to CLSI document M38-A2. Quantitative changes in aflR gene level of expression were analyzed by Real-time PCR method.Results: Our result obtained that the MIC of extracts on A. parasiticus growth 250 mg/mL for D.aucheri and 800 mg/mL for A.galanga L. D.aucheri has antitoxic properties as well as its effective ability to decrease aflatoxin production. The level of aflR gene expression was decreased significantly after the exposure of fungal cell to D.aucheri extract, but A.galanga L didn’t have significant effect.Conclusion: This research indicated that D.aucheri has antifungal effects more than A.galanga L. Due to our obtained result we can suggest that D.aucheri herbal extract may have antifungal potential in medicine or agriculture

First report of Vulvovaginitis due to Cryptococcus magnus in Iran

Background and Purpose: Cryptococcus. magnus is a non-Cryptococcus neoformans species isolated from certain plants, soil, air, and arctic glaciers. Case report: This report describes a case of a 23-year-old Iranian female with pruritus and vaginal irritation. Conventional tests and molecular analysis of the samples of vaginal discharge were performed. The mentioned analyses revealed Cryptococcus magnus as the causative agent of vaginal infection. The minimum inhibitory concentration analysis revealed that this species is susceptible to itraconazole, fluconazole, ketoconazole, and amphotericin B. The patient received 200 mg of oral ketoconazole once daily for 10 days. The patient did not show any clinical signs of vaginal infection after six months. Conclusion: C. magnus was found to have the ability to cause vulvovaginitis. This is the first report of successful detection and treatment of vulvovaginal infection with C. magnus

Changing economic systems and institutional dimensions of the Triple Helix model

Abstract In recent decades, many efforts have been put into understanding and determining key variables and factors affecting knowledge-based economy. Triple Helix model is a model with relative success in this regard; however, there is still a long way to go until it can provide policy makers and researchers with an inclusive and deep insight. Researchers of the current study strived to distinguish one of the main theoretical shortcomings of the model, i.e., considering reward systems reformation firmly fixed in the institutional framework of society, while introducing an overview of the Triple Helix model and its underlying logic using a descriptive-analytical method based upon theoretical framework of new institutionalism. This paper aims to highlight that, in the developing countries’ path toward a knowledge-based economy, reward systems reformation plays a key role and it is worth to be considered in models of determining the knowledge-based economy, the Triple Helix model, in particular

The Effect of Chenopodium Album and Apium Nodiflorum on the Expression of the Regulatory Gene (aflR) that Produces Aflatoxin in Aspergillus parasiticus

Background and Aim: Aflatoxins which are mainly produced by Aspergillus parasiticus are among the highly toxic secondary metabolites. This species often contaminates food and agricultural products including cereals, peanuts, and crops in the field. Recently, a number of studies have been carried out on the elimination of aflatoxin, and the antifungal effects of medicinal herbs, such as Chenopodium album  (36HYU2385) and Apium nodiflorum (36HYU2362). In this study, the effects of C. album and A. nodiflorum as natural compounds were examined on Aspergillus parasiticus growth, aflatoxins production and the aflR gene expression. Materials and Methods: The antifungal susceptibility testing of C. album and A. nodiflorum were performed according to CLSI document M38-A2. Quantitative changes in aflR gene level of expression were analyzed by Real-time PCR method. Results: Results indicated that minimal inhibitory concentration (MIC) in the extracts of C. album and A. nodiflorum against A. parasiticus growth were 100 mg/ml and 120 mg/ml respectively. Extracts of Chenopodium album and Apium nodiflorum have antitoxic properties. Moreover, they effectively decrease aflatoxin production. The level of aflR gene expression was decreased significantly after the exposure of fungal cells to the extracts. The highest inhibition was observed in MIC= 100 mg/ml of C. album. Conclusion: According to the results, it can be suggested that these herbal extracts may have antifungal potential to be used in medicine or agriculture
