Introduction: Cutaneous leishmaniasis is one of the health concerns in Iran. Numerous studies have examined the role of blood type in people with the disease. Therefore, this study aimed to investigate the prevalence of leishmaniasis in different blood groups as a review in Iran. Materials and Methods: For this review, two researchers evaluated the extracted articles in terms of relevance to the purpose of the study after searching four databases, including Scopus, Web of Science, PubMed, and Science Direct. Literature reports on the prevalence of leishmaniasis in different blood groups in Iran until the end of March 2021. Relevant information included study time, study tool, number of subjects, mean age, and the relationship between blood type and infection which were recorded in Excel form. Results: After searching, screening, and qualitative evaluation of the studies, out of 135 identified articles, five papers met the required requirements. These five articles were published from 1999 to 2012, three studies examined the relationship between cutaneous leishmaniasis with different age groups. Also, three studies experimentally evaluated the relationship between cutaneous leishmaniasis with different human blood groups. Conclusion: According to the results of the present review, cutaneous leishmaniasis is more common in some blood groups. Studies have shown that Rh-negative blood groups with B alleles are more affected by cutaneous leishmaniasis than others; however, more studies are required.

Introduction: Since phthalate esters and their derivatives have the potential to disrupt proper endocrine function, these compounds are considered as one of the most important groups of endocrine-disrupting chemicals. The presence of these compounds in various aquatic environments has caused main concerns about human and animal health and causes problems in the environment. Materials and Methods: The treatment process was carried out in a glass reactor containing 200 mL polluted water at room temperature. The Mg-Al layered double hydroxides (Mg-Al-LDH) were successfully synthesized and were applied as adsorbents for the removal of Diethyl Phthalate (DEP) from polluted water. The kinetics and isotherm of the process were investigated to determine the exact mechanism of DEP removal from the water medium. Results: The Mg-Al-LDH was a surface area of 673 (m2 g-1), a total pore of 0.716 (cm3 g-1), and microspore volumes of 0.627 (cm3 g-1), and a pore diameter of 8.64 nm. The maximum DEP removal efficiency of 96.7% was obtained at the DEP concentration of 10 mg L-1, Mg-Al-LDH dosage of 0.50 g L-1, and the reaction time of 30 min. The second-order kinetic model well depicted the kinetics of DEP adsorption (R2 = 0. 99). The Langmuir isotherm model best described the data by predicting the maximum adsorption capacity (qm) of 95.6 mg g-1 and R2 of 0.99. Conclusion: All the results demonstrate that the Mg-Al-LDH is an efficient, safe, and efficient adsorbent in water and wastewater treatment.

Introduction: The post-harvest damage to fruits is estimated to be about 10-30% of the total products, which reaches up to 30-50% in some perishable fruits. About 25 species of fungi and bacteria including Botrytis spp. and in particular Botrytis cinerea are known to contaminate fruits, vegetables and ornamental greenhouse plants. The aim of this study was to investigate the antifungal activity of different concentrations of Zataria multiflora essential oil (ZEO) against B. cinerea. Materials and Methods: The ZEO was extracted through steam distillation and analyzed by gas chromatography-mass spectrometry. The strawberries packages were exposed to ZEO with different concentrations (0, 200, 400, 600, and 800 ppm) and satarch nanoparticles. The exposed fruits were kept for 24 days at two temperatures of 20°C and 4°C. Results: The ZEO decreased mycelium growth even when only 200 ppm of it was added to each container. The response was dose-dependent, so that the 800 ppm dose of ZEO showed complete inhibitory effect. The minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) values for ZEO against B. cinerea were 200 µg/mL and 500 µg/mL, respectively. Additionally, ZEO preserved the sensory characteristics. Conclusion: The ZEO may be effectively used in packaging of strawberry to increase its shelf life by inhibition of B. cinerea.

Introduction: Understanding the epidemiological pattern and causes of poisoning is the first step to prevent and reduce complications and mortality due to poisoning in children. Given that no study has been conducted on this subject in Yazd, this study aimed to determine the epidemiology pattern of poisoning in children admitted to the referral teaching hospitals in Yazd and Taft cities during 2014-2019. Materials and Methods: This descriptive cross-sectional study was conducted on 238 children under the age of 15 who have been admitted to Shahid Sadoughi hospital in Yazd and Shahid Beheshti hospital in Taft city during 2014-2019. The data were analyzed by SPSS version 20.0 using descriptive statistics, Pearson correlation, and Chi-square. In all the statistical analyses, a P-value of less than 0.05 was considered significant. Results: The results showed that the frequency of poisonings was higher in girls (58%), in summer (31.1%), and in urban areas (82.8%). Most cases of poisoning aged less than 15 years (75.1%). The main cause of poisoning in children was drug poisoning (60.5%), followed by cleansing products (10.1%). The most common clinical manifestations included neurological signs (33.6%). During 2014-2019, the frequency of drugs and pesticide poisonings decreased; while poisoning due to drug-opioids and cleansing products increased (P = 0.04). Also, 3 deaths occurred due to poisoning during this period. Conclusion: The higher prevalence of drug and cleansing products poisoning in children under the age of 15 indicates involuntary poisoning in this group. Therefore, proper storage of these substances and more parental care can reduce poisonings in children.

Introduction: Fungal aerosols cause life-threatening infections in patients hospitalized in critical wards. Antiseptics and disinfectants have broad-spectrum antimicrobial activity against the living tissue and inert surfaces microorganisms; hence, they have an essential role in controlling and preventing nosocomial infections. This study aimed to evaluate in vitro antifungal activity of benzalkonium chloride (BAC), chlorhexidine digluconate (CHX), and sodium hypochlorite (SH) against isolated fungal aerosols from the hospital environment. Materials and Methods: The susceptibility tests were performed on fungal aerosols isolated from various wards of Children’s Medical Center, based on broth microdilution antifungal susceptibility testing of filamentous fungi approved by the Clinical and Laboratory Standards Institute (CLSI) M38-A2 document. The isolates included Aspergillus (Aspergillus flavus (n = 14), Aspergillus niger complex (n = 12), Penicillium spp. (n = 14), and Cladosporium spp. (n = 14). Results: The geometric means (GM) of the Minimum Inhibitory Concentrations (MICs) of the biocides across all isolates were as follows: BAC, 3.56 µg/ml, CHX, 9.45 µg/ml, and SH, 810.35 µg/ml. The highest range of MICs was found for SH (50-12800 µg/ml), while the lowest range was for BAC (1-16 µg/ml) against all fungal isolates. Generally, BAC showed the highest in vitro activity among disinfectants tested. The lowest MIC50 and MIC90 values were 4 and 8 µg/ml for BAC, followed by 16 and 32 µg/ml for CHX, and 800 and 6400 µg/ml for SH, respectively. Conclusion: The findings showed that BAC was an effective disinfectant, which can prevent resistant species and fungal pathogens and be used an alternative to other disinfectants and antiseptics.

Introduction: The aim of this study was to identify all activities to be sufficiently prepared for emergencies in the power plant industries using the method of the Federal Crisis Management Organization in the south Isfahan power plant. Materials and Methods: In this research, a checklist tool of 117 questions in 9 sections based on the FEMA method has been used. Checklists were localized. To check the face and content validity of the checklists, the opinions of three technical experts were used, and to check the reliability of the research subjects, the test-retest test was used, and to measure the reliability of the checklists, Cronbach's alpha coefficient was used with an emphasis on internal correlation. The obtained alpha coefficient was 0.76. Data were analyzed using SPSS software. Results: The results showed that the power plant preparedness for general emergencies is 77.5%, winter storms and extreme cold 80%, storm 73.33%, overheating 70%, chemical storage 88.57%, earthquake 65%, Fire and explosion is 87%, flood 63.33%, and lightning 92%. The highest level of preparedness with 92% was related to the lightning checklist and the lowest level of readiness with 63.33% was related to floods. Conclusion: In general, despite the differences in the readiness of the power plant against various accidents, the average level of preparedness for all accidents is higher than average. However, a number of appropriate measures must be taken in each area and the level of preparedness must be increased in cases such as fires and explosions.

Introduction: Endocrine disruptive compounds as a class of organic contaminants in the aquatic environment received severe attention in the last decades. The release of bisphenol A (BPA) as a hazardous organic chemical into the environment has caused high health and environmental concerns. Therefore, its removal from aquatic environments is strongly recommended. The present study deals with BPA removal efficiency from an aqueous environment using the electrocoagulation process (ECP). Materials and Methods: The effects of parameters including BPA concentration (1-10 mg L-1), current density (3-15 mA cm-2), pH (4-10), and reaction time (5-30 min) on the treatment process were investigated. Response surface methodology (RSM) was employed for optimization of the ECP. The significance of the developed model was investigated by the obtained F-value and P-value. Results: The maximum BPA removal of 98.2% was attained at pH of 8.5, BPA concentration of 3.25 mg L-1, the current density of 12.0 mA cm-2, and reaction time of 23 min. The significance of the developed model was confirmed by the high F-value of 46.69 and the very low P-value of < 0.0001. Furthermore, the electrical energy consumption of the process was found to be 0.308 kWh m-3 in the optimum condition. Conclusion: The obtained experimental results revealed that the co-precipitation and the adsorption process through the electrostatic interactions as the main removal mechanisms controlled the treatment process.

Introduction: Contamination of water with heavy metals has turned into a health concern, particularly in the developing countries. In this study, concentration of heavy metals and associated carcinogenic and non- carcinogenic risk was investigated in water samples collected from Gonbad-e Kavus, a high-risk area for cancer. Materials and Methods: Samples were collected from Gorgan River, Golestan reservoir and wells around villages with high prevalence in 2018. Samples were analysed through inductively coupled plasma mass spectrometry. After determining the concentration of heavy metals in water samples from different sources, health risk assessment was carried out according to the Environmental Protection Agency. Results: Arsenic in samples 6-9 was higher than 10 µg/L, calcium and magnesium in sample 5 was higher than 200 mg/L and 150 mg/L respectively, and sodium in all samples was higher than 50 mg/L. According to the findings, these concentrations were higher than the maximum allowed limit in most water samples. Hazard quotient (HQ) in samples 8 and 9 were associated with arsenic and health risk in sample 1 was related to antimony. Furthermore, since all samples contained high amounts of lithium, water from this area better should not be consumed by children older than one year. Conclusion: Given the high rate of arsenic contamination, consumption of water in the study area could be health threatening for all individuals and is not recommended for children. This highlights the need for taking immediate actions to review the water treatment process and ensure safety of the drinking water in this area.

Introduction: Soil remediation is one of the most important fields in environmental studies. This study was conducted to investigate the effect of indole-3-acetic acid (IAA) and humic acid (HA) on increasing the bio-degradation of diesel oil in soil polluted with (lead) Pb and cadmium (Cd). Materials and Methods: Treatments included foliar application of IAA (0 (control) and 30 ppm) and soil application of HA (0 (control) and 200 mg/kg soil) in the soil contaminated with Cd (0 (control), 10 and 15 mg/kg soil), Pb (0 (control) and 1600 mg/kg soil), and diesel oil (0 (control), and 8% (W/W)). The sunflower was planted in all soil samples. The plants were harvested after 70 days and Pb and Cd concentrations of plants were measured using Atomic Absorption Spectroscopy. Results: Foliar application of IAA at the rate of 30 mg/l significantly increased the Cd and Pb phytoremediation by 14.8% and 13.4%, respectively. For HA application, it was increased by 11.3% and 10.2%, respectively. A significant increase was found in degradation percentage of diesel oil in soil by 12.6%, when the soil was treated with 200 mg HA/kg soil. Conclusion: It can be concluded that application of organic amendments such as IAA or HA can be a suitable way for increasing plant growth and increasing plant phytoremediation efficiency, especially in the soil contaminated with diesel oil. However, the phytoremediation efficiency is dependent on the plant physiology and the type of soil pollution that should be considered.
