This novel RNA virus enters cells by binding to angiotensin-converting enzyme II (ACE2) receptors. Additionally, ACE (ACE1) polymorphisms can influence ACE2 activity and consequently affect COVID-19 patient outcomes. This study aimed to determine the genotypic and allelic frequencies of the insertion/deletion polymorphism (ACE I/D; rs4646994) in the ACE gene among Arab Jordanians. Moreover, we investigated if there is a genetic association between the allele and genotype frequencies of the rs4646994 polymorphism with respect to gender. We isolated DNA from approximately 525 blood samples for genotyping of the ACE I/D polymorphism, which was performed using a 3% agarose gel mixed with ethidium bromide. Our findings indicated a significantly higher distribution of the D allele (66%) compared with the I allele (34%) in the Jordanian population. Moreover, the DD genotype (42%) was more prevalent than the II genotype (11%). We observed a significant association in the genotypic frequency, but not the allelic frequency, between males and females. Our research has revealed the potential role of the ACE I/D variant in the increased COVID-19 morbidity and mortality rates in the Jordanian population.</p></div>","PeriodicalId":52875,"journal":{"name":"Journal of Biosafety and Biosecurity","volume":"5 3","pages":"Pages 89-95"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43618502","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}

It is also important to incorporate convergent domains of scientific endeavors in biological and particularly computer and information sciences, upon which the life sciences increasingly depend. Indeed, the rapid development of science and technology may be outpacing necessary ethical and regulatory practices. Thus, governments and civil society often struggle to anticipate emerging capabilities and to identify and implement appropriate oversight mechanisms, particularly for activities that occur outside the direct oversight of government programs. However, these efforts are critical for public health and serve as an extremely powerful action to counter the use of biological weapons.</p></div>","PeriodicalId":52875,"journal":{"name":"Journal of Biosafety and Biosecurity","volume":"5 3","pages":"Pages 116-117"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45806424","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}

Mpox is emerging as a global public health threat from a seemingly neglected disease. A42R profilin-like protein from mpox virus (PDB ID: 4QWO) could be a preferred target lead. The binding affinity of commonly used drugs/mAbs (tecovirimat, brincidofovir, cidofovir) for A42R profilin-like protein was examined <em>in silico</em> through molecular docking. Further, the results were compared with those of the phytochemicals curcumin, rutin, and theaflavin. Tecovirimat (−7.31 kcal/mol, IC₅₀ = 4.39 µM) and theaflavin (−6.99 kcal/mol, IC₅₀ = 7.54 µM) had the highest affinities. Molecular dynamics simulation of the theaflavin–4QWO complex was performed to ascertain the stability of ligand–protein interactions in natural charge, molecular electrostatic potential, and frontier molecular orbital analyses. The predicted QSAR and pharmacokinetic properties of all compounds were evaluated to find a suitable candidate for designing and developing new drugs. The evaluated log P values for brincidofovir and tecovirimat were higher than those of the other drugs in the QSAR study. Theaflavin had an impressive log P of 4.77, which hints at its high biological activity. The findings recommend further <em>in vitro</em> experimental validation to develop potential low-cost mpox therapies.</p></div>","PeriodicalId":52875,"journal":{"name":"Journal of Biosafety and Biosecurity","volume":"5 3","pages":"Pages 118-132"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49870553","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 aim of this study is to evaluate the physico-chemical quality of the ashes, effluents and the range of equipment that produce the much effluent and pollutions.</p><p>This is a descriptive and cross-sectional study of 82 laboratories followed by the sampling of effluents from automatons. The physico-chemical parameters and trace elements are determined according to French Standardization Association (AFNOR) standards and used atomic absorption spectrometers and molecular absorption spectrometers. The Mindray hematology automaton is used for 64.7% and 81.5% of the cans are used to collect waste. Semehow 77.8% of discharges are released into sinks without adequate treatment in 42.6% of cases. Chemical analyses show that trace elements (TE) levels in effluents range from 5.89 ± 0.21 to 105.80 ± 0.96 μg/L for Arsenic; from 5.62 ± 0.34 to 6.53 ± 0.49 μg/L for Cadmium; 0.70 ± 0.01 to 10.63 ± 1.17 μg/L for Mercure and 35.72 ± 1.88 to 61.98 ± 5.15 μg/L for Plomb. pH ranges from 7.17 ± 0.65 to 8.3 ± 1.35 with total dissolved salts (TDS) range from 3260.20 ± 401.68 to 17117.41 ± 265.37 mg/L. All averages of contamination indices (CI) and polymetallic contamination indices (PCI) for post-incineration ashes are greater than 1.5 with the exception of Hg (0.22). For effluents, in addition to polymetallic contamination indices (PCI), CI in hematology effluents (1.09), all CI are less than 1. Hematology effluents have a lower pH and are much more mineralized and concentrated in trace elements while those from biochemistry and serology appear to be similar. However, the effluents of Biochemistry and Serology are more basic and concentrated in Suspended Solids with higher values obtained in Biochemistry. Although the physico-chemical parameters comply with WHO standards, discharges from automatons deserve appropriate treatment before their disposal.</p></div>","PeriodicalId":52875,"journal":{"name":"Journal of Biosafety and Biosecurity","volume":"5 3","pages":"Pages 107-115"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49870554","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}
