This disease produces rashes with lesions on the skin. The MPXD is an endemic in some countries of Africa, however, a recent outbreak of this disease started to appear in some countries, such as the United Kingdom, Spain, Greece, Portugal, Australia, Brazil, and the United States. Lots of indicators are employed for forecasting the 2022 outbreak of the MPXD such as the infection period, the recovery period, the force of infection, the incubation period of the disease…..etc. The aim of this study is finding the infection period, and the recovery period of the 2022 outbreak of the monkey-pox virus disease in two countries: the United States, and Spain. We apply the simulation and analytical methods on a simple epidemic model, which is the SIRD infectious disease model, for finding the previous periods. We found that the infection period of the recent outbreak of the MPXD varies from 10 days to 20 days, while we found that the recovery periods of the recent outbreak of the MPXD varies from 15 days to 30 days. Besides, we found that the average value of the infection period of the 2022 outbreak of the MPXD is about two weeks, and the average value of the recovery period of the 2022 outbreak of the MPXD is about three weeks. The analytical solution with the simulation algorithm which we used in this study can be expanded for other forecasting parameters of the MPXD, and also for multiple countries.","PeriodicalId":93771,"journal":{"name":"IOP SciNotes","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45012141","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}

In the submarine vent theory, it has been proposed that those minerals, especially mackinawite, had a key role in prebiotic processes. Those are estimated to be present in a natural electrochemical setting, analogous to a chemiosmotic one, formed in the interface between the early ocean and the interior of the alkaline hydrothermal systems, the early vent-ocean interface. To evaluate this and other hypotheses, voltammetric studies were performed to better understand the electrochemical behavior of minerals under conditions analogous to the vent-ocean interface. The preliminary results presented here indicate that, in the potential range estimated to exist in that interface, mackinawite can transition to other mineral phases and may posibly coexist with other minerals, resulting from its oxidation. This can create a local chemical diversity. In addition, it has been tested a protocol for Ni incorporation in mackinawite structure, resulting in a surface that showed an interesting behavior in the presence of CO2, although definitive experiments showed necessary for a deeper comprehension of that behavior. Overall, the results are consistent with previous results on electrocatalytical properties of Fe-Ni-S materials for CO2 reduction, and also could lead to the emergence of a protometabolism on early Earth.","PeriodicalId":93771,"journal":{"name":"IOP SciNotes","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47079044","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}

In this study effectiveness of five different chemical fixatives were evaluated on human fecal samples including for supernatant using RNAprotect® Bacteria Reagent (Qiagen), 95% ethanol, acetone, TRIzol® and a mixture of all these fixatives, in addition to immediate freezing. DNA was extracted from the fecal samples using QIAamp® Fast DNA Stool Mini Kit as well as quality and yield of extracted DNA was monitored for a period of 30 days. It was found that except TRIzol®, all other preservatives showed good DNA quality and yield for a period of one month based on agarose gel electrophoresis, Nanodrop and Qubit fluorometric measurements. It was also found that supernatant of fecal sample fixed with RNAprotect Bacteria Reagent gave reliable DNA yield in comparison to other various fixatives. The study also revealed that quality and yield of DNA from fecal samples fixed in acetone were very promising since it is a cost-effective fixative. Overall, the study shows future applicability for downstream DNA analyses of the RNAprotect® Bacteria Reagent, 95% ethanol, acetone, and a mixture of all these fixatives for fixing human fecal samples to be collected from geographically remote locations or in regions where available resources are largely limited.","PeriodicalId":93771,"journal":{"name":"IOP SciNotes","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43844001","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}
