However, little is known about the trace element (TE) concentrations in their muscles. To this end, a total of 82 pieces of V. persa and 74 A. braschnikowi were caught at three different fishing areas (Astara, Anzali, and Kiashahr) around the southwestern shorelines of the Caspian Sea from September 2017 through June 2018. An inductively coupled plasma optical emission spectrometry (ICP-OES) was used to measure the accumulation of 34 traces and macro elements in some tissues of the fish species. Then, comparisons of the element levels in these tissues were made for the three different fishing areas. Overall, in the case of A. braschnikowi, 30, 30, and 28 elements were detected in its skin, gonads, and kidneys, respectively, while in the case of V. persa, 27 and 28 elements were found in its muscle and liver, respectively. The majority of element levels measured in these tissues indicated no significant differences among the sampling areas (P>0.05) except for such elements as copper, lanthanum, and tungsten in skin, lanthanum, rubidium, and vanadium in gonads, as well as molybdenum and zinc in kidney (P<0.05). The capacity of observed elements put human health at risk were examined as well. The TE content in the tissues of A. braschnikowi and in the muscles of V. persa (P<0.05) differed significantly from the international standard levels (P<0.05). In this study, only lead indicated a target hazard quotient (THQ) index above 1. Therefore, high consumption of this fish (360 g per year) may be a matter of concern for the consumer. In the case of other evaluated elements, the THQ value was less than 1.","PeriodicalId":8672,"journal":{"name":"Avicenna Journal of Environmental Health Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47558222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Helicobacter pylori infection is typically acquired in childhood and the acquisition is associated with poor household hygiene. In this study, the current knowledge on the activity of essential oils and extract of Apium graveolens L. (celery seeds) and their derivatives against H. pylori was reviewed. Celery seeds were prepared at the Pharmaceutical Farm (Babol, Mazandaran) of Iran. The essential oils were extracted by a Clevenger approach and analyzed using GC-MS, and maceration method was used to prepare the extract. H. pylori bacteria were isolated by the cultivation of gastric biopsy removed from the patient who had gastric ulcer. The antibacterial activities of both essential oils and extract against H. pylori were evaluated by agar dilution method, and the corresponding MIC (minimum inhibitory concentration) and MBC (minimum bactericidal concentration) values were determined for each sample. The results showed that the main components in celery seed essential oils were α-pinene (20.25%), β-pinene (16.62%), and Sabinene (7.81%). Among different samples, essential oils of celery seed exhibited better effect on H. pylori with MIC value of 1.56 mg/mL and MBC value of 3.12 mg/mL. Methanol and water extracts of celery seed showed MIC values of 0.38 mg/mL and 0.78 mg/mL and MBC values of 1.56 mg/mL and 6.25 mg/ mL, respectively (P≤0.005). The results of this study indicated that all the samples had antibacterial effect against H. pylori due to antibacterial components.","PeriodicalId":8672,"journal":{"name":"Avicenna Journal of Environmental Health Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44620193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides being rarely clean, the mobile phone is a potential reservoir of disease and pathogens and hospital infections on bedside of hospitalized patients. In this study, the microbial contamination of mobile phones and potential of transmitting infections and their antibiotic resistance pattern were investigated. In this descriptive cross-sectional study, a questionnaire was prepared to assess the importance of maternity, neonatal, and intensive care unit (ICU) staff attention to how to use and clean the cell phones in terms of valid sources. Samples were taken from 116 cell phones using a sterile swab. The standard plate count was used to detect the existing bacteria, and the antimicrobial resistance patterns of isolated bacteria were determined by standard methods. The microbial culture experiments indicated that 107 cell phones had microbial contamination, accounting for 92.24% of mobile phones. From 132 isolated strains, 115 strains (87.12%) were gram-positive while 17 were Gram-negative (12.88%). Furthermore, 67 (57.76%), 9 (7.7%), 4 (3.45%), 10 (8.62%), 12 (10.35%), 22 (19%), and 8 (6.9%) strains were coagulase-negative staphylococci, Pseudomonas aeruginosa, Staphylococcus aureus, Corynebacterium, Bacillus, Streptococcus, and Escherichia coli, respectively. The results of this study indicated that cell phones were contaminated with different types of bacteria, and that all species isolated partially played an important role in the development of hospital-acquired and opportunistic infections. Therefore, continuous disinfection of mobile phones and non-use or limited use of them in the hospitals are recommended.","PeriodicalId":8672,"journal":{"name":"Avicenna Journal of Environmental Health Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46664912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was performed to find the concentration of heavy metals (arsenic, lead, iron, and zinc) in drinking water sources of Divandarreh in Kurdistan province and prepare its zoning map. A total of 99 wells, springs, and reservoirs were selected for sampling in 78 rural areas of Divandarreh County. Samples were collected from each source using grab sampling methods in two phases (rainy and dry seasons). To find the concentration of lead, the atomic absorption device (VARIAN 240 AA) was used, and Inductively Coupled Plasma (ICP: VARIAN 710) was used for determining the concentration of arsenic, iron, and zinc. Analysis of data was done using SPSS version 22.0 and the analysis of spatial variability and estimation of the concentration of heavy metals (preparation of zoning map) in the study area were carried out by ArcGIS software. The average concentrations of arsenic, lead, iron, and zinc in dry and rainy seasons were 1, 0.6, 62.9, 31.4, and 0.13, 2.16, 11.5, 19.8, respectively. Zinc, iron, and lead concentrations in sample No. 36 were higher than the standard level; therefore, it can be inferred that these three elements can create health problems in the future.","PeriodicalId":8672,"journal":{"name":"Avicenna Journal of Environmental Health Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45609167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The wastewater of these industries contains high amounts of pollutants which can be toxic, carcinogenic, and mutagenic and needs to be treated before being discharged into the environment. The aim of this study was to evaluate the application of eggshell as a sorbent for the removal of Acid Orange 3 from synthetic wastewater. This study is applied experimental research which was performed on a laboratory scale. Eggshell as a sorbent was prepared at laboratory temperature and pulverized by standard ASTM sieves in two sizes (50 and 140). The concentration of dye in the synthetic wastewater was 25 mg/L. In this study, increasing adsorbent dose from 2 to 5 g/100 mL led to an increase in the adsorption efficiency from 36.6% to 55.36% and by decreasing the size of eggshell particles from 50 to 140 mesh, the adsorption efficiency increased. The maximum adsorption took place in the first 90 minutes of the reaction. By increasing pH from 5 to 9, the process efficiency increased from 78 to 82%; however, at pH higher than 9, the adsorption efficiency decreased. Additionally, the adsorption characteristics of this pollutant on eggshell fitted Freundlich isotherm (R2 >0.989). Due to the characteristics of textile wastewater such as alkaline pH, eggshells can be used as a natural adsorbent in textile wastewater treatment.","PeriodicalId":8672,"journal":{"name":"Avicenna Journal of Environmental Health Engineering","volume":"7 1","pages":"72-77"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49149275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increase of sea surface temperature is inversely related to the resistance of corals and is directly associated with their bleaching. High temperature disrupts the symbiotic relationship between coral and algal symbiont and results in coral bleaching. To evaluate the adaptation of corals to heat stress, in this study, we investigated the thermal stress effect on the expression of genes involved in programmed cell death (PCD), cysteinyl aspartate proteases 3 (will be mentioned as Caspas3 hereafter) and anti-apoptotic pathway, B-cell lymphoma 2 (will be mentioned as Bcl2 hereafter) in Porites lobata (Dana, 1846). Corals were incubated at 25°C for 2 weeks (adaptation period) and then exposed to 34°C (heat shock) for 24 and 48 hours. Then, the expression of genes was measured using real-time PCR. The results revealed that both genes were up-regulated at 24 hours after heat induction. Bcl-2 expression (anti-apoptotic gene) was induced at 24 hours and was down-regulated at 48 hours. In contrast, Caspase3 (apoptotic gene) continued to be expressed up to 48 hours. These results might indicate that coral cells are headed towards bleaching and death with increased temperature. The results of this study, regarding the observed expression patterns, can clarify the response of different genes to a thermal stress in coral reefs. The exposure of corals to acute conditions with high temperatures presented the behavior of the desired genes in the studied conditions.","PeriodicalId":8672,"journal":{"name":"Avicenna Journal of Environmental Health Engineering","volume":"7 1","pages":"28-33"},"PeriodicalIF":0.0,"publicationDate":"2020-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45111336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
