Nanoclay Performance on Resistance of Clay under Freezing Cycles

This study aims to investigate effect of nanoclay on resistance of the exposed clay soils in freezing in vitro conditions. The clay sample was selected from the considered land. Then they were mixed on water in 1.5, 3, 4.5 and 6 percents as well as without nanoclay. There were prepared cylinders with 3.81 cm diameter and 7.62 cm height, which they have been placed in conditions without freezing, one cycle, two cycles and three cycles of freezing. Then they were tested under uniaxial experiment. Then they were analyzed by SPSS software. The results show that adding nanoclay with 1.5, 3, 4.5 and 6 percents will reduce soil strength during freezing cycles. It can be occurred because adding nanoclay will result to increase special surface of the samples; consequently, increasing electrical load increases water absorption, which it can be partly cause of non-effective increasing nanoclay in soil resistance. There is also a significant difference between pressure strength of soils with lower humidity and those with higher humidity. It confirms that increasing humidity decreases strength level, which increasing water absorption of samples by nanoclay is reason of decreasing strength. There is an inverse significant relationship between increasing nano and soil water absorption, which its reason may be that adding nanoclay because of increasing samples special surface and consequently, increasing electricity load will increase water absorption and samples’ plasticity. It can be expected that samples’ permeability will decline by increasing their plasticity. There is also a significant relationship between increasing nano and soil liquid and doughiness limit that its reason can be increasing rate of water absorption in samples due to presence of nanoclay.© JASEMKeywords: Nanoclay, Resistance, Freezing, Sample, Uniaxia

Survey of epidemiological of parasitic and bacterial infection in cultured fishes of Khouzestan Province

In this study which was carried out in khouzestan province, 1914 Pieces (1160 Pieces silver carp, Hypophthalmychthys molitrix; 498 Pieces common carp, cyprinus carpio; 172 Pieces Grass carp, ctenophryngodon idella and 84 Pieces Big head, Arysthychthys nobilis) from different parts of the province were examined. In three year period, 1378 to 1381, fish samples from four stations were transferred a live to the lab. Water samples also were taken and tested for some of the physicochemical factors. From a total of 1914 fish examined, 1190 showed parasitic infestation and bacterial infections (62.2%). Infestation study, infestation with these parasites have been found: Ichthophthirius, cryptobia, Trichodina, Costia, Hexamita, Dactylogyrus, Gyrodactylus, Lernea, Bothrio cephalus, Diplostomum and Capillaria. Also some species of Aeromonas, staphylococcus, Moraxella, Pectobacterium, Flavobacterium, Citrobacteria, pasteurella, Psedomonas and Alcaligenese were identified in the samples, which normally occur in Water, but in some conditions (High pH, temperature and ammonia) could cause disease and lesions specially in gills. Infestation with dactylogyrus and Gyrodactylus was found in all four kind of fishes with different infestation rate. But the highest infestation rate with dactylogyrus was in silver carp (55.2%) and lowest in common carp (14.6%). The highest infestation rate with gyrodactylus was in grass carp (42.4%) and lowest in common carp (10.6%). Ich, Bothrio cephalus and capillalia were found only in common carp and grass carp. Infestation with adult lernea and copepodid stage of lernea had greater percentage in the gills and derm of grass carp. The data showed infestation with this parasites (especially protozoans and lernea) and bacterial infection had occurred in all seasons especially in C area

Adjunctive treatment of myxopapillary ependymoma

Myxopapillary ependymoma are rare tumors and optimal therapeutic strategy is remained controversial. The main treatments for myxopapillary ependymoma tumors include surgery and radiotherapy. Hence, the present study aimed to review adjuvant treatment of myxopapillary ependymoma, focusing on spinal myxopapillary ependymoma. The information sources of all articles were the English authoritative databases including PubMed, Web of science, Scopus, Science direct and Google scholar. In this review study, the keywords including adjuvant, treatment, myxopapillary and ependymoma were selected from MeSH medical library. Related articles were published from 2000 to 2020. Given radiation tolerance in the spinal cord is 10-15 lower than that of the brain, it also should be noted that with increased dose and scope of therapeutic field, the corresponding risks are increased, as well. Also, chemotherapy has never been used as the primary treatment approach. Radiotherapy s value is considered while involving with sensitive areas where chemotherapy is also recommended. Gross total resection is the preferred primary treatment. © 2021 Page Press Publications. All rights reserved

Iranian and American Moral Judgments for Everyday Dilemmas Are Mostly Similar

Moral judgment is a complex cognitive process that partly depends upon social and individual cultural values. There have been various efforts to categorize different aspects of moral judgment, but most studies depend upon rare dilemmas. We recruited 25 subjects from Tehran, Iran, to rate 150 everyday moral scenarios developed by Knutson et al. Using exploratory factor analysis (EFA), we observed that the same moral dimensions (except socialness dimension) were driven by the same moral cognitive factors (norm violation, intention, and social affect) in Iranian vs. American studies. However, there were minor differences in the factor loadings between the two cultures. Furthermore, based on the EFA results, we developed a short form of the questionnaire by removing eleven of the fifteen scenarios from each of the ten categories. These results could be used in further studies to better understand the similarities and differences in moral judgment in everyday interactions across different cultures. © Copyright © 2021 Yazdanpanah, Soltani, Mirfazeli, Shariat, Jahanbakhshi, GhaffariHosseini, Alavi, Hosseinpour, Javadnia and Grafman

Curcumin anti�tumor effects on endometrial cancer with focus on its molecular targets

Curcumin is extracted from turmeric and shows a variety of properties that make it a useful agent for treating diseases and targeting different biological mechanisms, including apoptosis, angiogenesis, inflammation, and oxidative stress. This phenolic compound is safe even at high doses. However, it has poor bioavailability. The incidence rates of endometrial cancer (EC) that is one of the most prevalent gynecological malignancies is increasing. Meanwhile, the onset age of EC has been decreased in past few years. Besides, EC does not show a convenient prognosis, particularly at advanced stages. Based on this information, discovering new approaches or enhancing the available ones is required to provide better care for EC patients. In this review, we cover studies concerned with the anti-tumor effects of curcumin on EC. We focus on molecular mechanisms that are targeted by curcumin treatment in different processes of cancer development and progression, such as apoptosis, inflammation, and migration. Furthermore, we present the role of curcumin in targeting some microRNAs (miRNAs) that may play a role in EC. © 2021, The Author(s)
