The current study intends to monitor the hydrogeochemical processes of water resources in Egypt's west Luxor area. In August 2021, 79 surface, shallow, and groundwater samples were collected in the study area. In this investigation, three statistical techniques were used: classical, cluster hydrogeochemical statistical analysis (CA), and geo-statistical analysis. Water characteristics are mapped using the Kriging method, which is a Geo-Statistical tool in ArcMap 10.4.1. The laboratory results of the Piper trainer diagram integration (CA) and geo-statistical prediction maps showed that cations (Na + > Ca 2+ > Mg 2+ > K + ) and anions (Cl - > SO 42- > HCO 3- > CO 32- ) dominated. The majority of water types in all samples were Na-Cl, Mixed Na-Cl-HCO 3 , Mixed Na-Cl-SO 4 , and Mixed Na-Ca-Mg-HCO 3 . Prediction maps coincide with hydro-geochemical statistical analysis, which showed that salts and measured heavy metals (Fe, Mn, Co, Ni, Cd, Pb, As) levels in groundwater and shallow water samples were greater than those of Egyptian Standard Limits, while surface water had high pH, HCO - , and CO 32- levels, indicating pollution sources. As a result, this study found that combining geostatistical and classical hydrogeochemical statistical analysis produced a good assessment of both natural water processes and water quality in the west Luxor area.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"29 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82842594","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}

By mid-March 2021, the COVID-19 had practically hit every country on the earth. As a primary precaution to prevent the spread of disease and mortality, some nations have implemented quarantines and the suspension of many activities. The termination of these activities has resulted in significant economic losses. However, it has been widely reported that these steps have improved air quality, particularly in highly polluted areas with considerable populations and industrial activity. Worldwide reports and verification of lower carbon, nitrogen, sulphur, and particulate matter emissions have been made in relation with shutdown times. On the other hand, it has been revealed that ozone levels in the ambient air have increased, owing mostly to lower nitrogen emissions. Furthermore, it has been claimed that natural water resources have higher water quality. Wastewater treatment plants have reported an increase in organic load with persistent chemicals as a result of increased use of sanitizers, disinfectants, and antibiotics. In general, the qualitative and quantitative volumes of solid waste, created as a result of the COVID-19 outbreak, have both increased. This study presents and summarises the environmental impacts of COVID-19 as recorded in the literature for various countries throughout the world, which provides a comprehensive perspective of the COVID-19's environmental consequences.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"20 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74040493","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}

Twenty-one morphometric measurements were taken by a threaded micrometer in addition to the assessment of whole body metabolites. Results showed a spatial significant variation within morphometric traits between different populations; where the morphometric trait in South Sinai was clear different than others, followed by, the population of the Nile Delta, the clade of the western desert Oases and the Mediterranean coastal desert. According to Canonical Correspondence Analysis, the total amount of protein and carbs in their food was significantly correlated with the diversity in biochemical features. The closer population was between the western desert Oases and Nile Delta regions.

These developmental changes are reflected in the parasites’ morphology, infectivity, gene expression patterns, as well as levels. Midgut and hemolymph sporozoites are completely different from those of salivary gland ones in that they are less capable for infecting their hosts and are less motile. The mosquito factors triggering those developmental changes during, and post salivary gland invasion are largely unknown. To identify and characterise mosquito factors that trigger those essential developmental changes in Plasmodium berghei and strengthen sporozoite development to infect their mammalian host, a UIS4: mCherry -containing line of P. berghei ( Pb ANKA- Cherry- 2204c1) that only has visible mCherry expression following salivary gland invasion, was treated in vitro with adult female mosquito tissue homogenates. The data obtained from using female Anopheles stephensi salivary gland homogenate shows the expression of mCherry protein as red fluorescence in about 70% of treated sporozoites in vitro . Anopheles stephensi midgut homogenate (non-specific tissue), and Aedes aegyptie salivary gland homogenate (non-vector salivary gland) were used as well as UIS4, UIS7, and mCherry genes expression were compared with midgut sporozoites. Treated sporozoites have a transcription profile of the tested genes like that of salivary gland sporozoites. Although the variables causing Plasmodium development following mosquito salivary gland invasion may not be influenced by mosquito species, it does show tissue specificity. As a result, the salivary gland's function as a gateway and invasion is the most crucial and specific phase in disease transmission.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"278 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89209882","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 formation of carbapenemases such metallo-β lactamases (MBLs), which hydrolyze a variety of β-lactams including penicillin, cephalosporins, and carbapenems, is one of the primary causes of resistance in Acinetobacter baumannii. MBL-producing carbapenem-resistant strains have been detected all over the world in recent years, and at a rising pace. For this investigation, fifty-two A. baumannii isolates were chosen based on imipenem (IMP) resistance (MIC >16 g/ml). The Modified Hodge test (MHT) and the CDDT were used to detect MBL phenotypic expression (Combine Disk Diffusion Test). PCR was used to detect genotypic expressions of the blaIMP-1 and blaIMP genes in all metallolactamase-producing A. baumannii strains. According to the MHT test, 49 of 52 A. baumannii isolates (94.2%) produced carbapenemase, whereas the CDDT test revealed that 47 isolates (90.4%) produced MBL. Despite being negative for MBL-producer in the phenotypic technique used for control isolates, 39 (75%) of 52 putative MBLproducer isolates were positive for the blaIMP-1 gene by PCR, while fifteen A. baumannii isolates (28.8%) were positive for the blaIMP gene by PCR. In 23% (12/52) of instances, the blaIMP-1 and blaIMP genes were found together. The genotypic approach must be used to confirm isolates of A. baumannii that have been identified as MBL-producers using the MHT test and the Combine Disk Diffusion Test.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73487210","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 antifungal properties of spices and Ganoderma mushroom, as food preservatives, against seven toxigenic fungi isolated from Egyptian rabbit, poultry, and cow feed were investigated in this study. The growth diameter of fungal colonies was measured separately on plates of Potato dextrose agar medium with different spices at a concentration of 60 g/L. Clove, cinnamon, and turmeric completely inhibited all of the fungi tested, while the rest of the spices had a moderate to variable inhibitory effect, and several spices (coriander, fennel, anise, and caraway) even promoted the fungal growth. The five best effective spices with 16 concentrations (0.05 to 100 g/L) were used to find minimum inhibition concentration (MIC) and minimum fungicidal concentration (MFC) for each fungal isolate separately. Clove and cinnamon were the most effective spices against all tested fungal isolates, with MIC of 0.05-1 g/L and MFC of 3-10 g/L. Hence, clove and cinnamon are recommended, as the best antifungal spices that can easily inhibit fungal growth at a minimal concentration. Mycelial plugs of Ganoderma mbrekobenum exhibited a high inhibition activity against the growth of Monascus ruber, Aspergillus ochraceus, and Penicillium sp. The antifungal activities of aqueous and organic extracts of Ganoderma mushroom were investigated, and the methanol-chloroform extract was shown to have the maximum activity, making it a good antifungal agent.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"20 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82105922","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}
