These models help to investigate the basic dynamics and quantitative behavior of infectious diseases that affect human beings, such as COVID-19, hepatitis B virus (HBV), and human immunodeficiency virus (HIV). The current study investigates the spread of HBV by using the basic virus model. In order to determine the stability of disease-free and endemic equilibria, the basic reproduction number is determined. The convergence and divergence of disease-free and endemic equilibria are demonstrated by using standard finite difference (SFD) and non-standard finite difference (NSFD) schemes. Arguably, SFD schemes, namely Euler and Runge-Kutta order four (RK-4) schemes, converge for lower step sizes, while the NSFD scheme converges for all step sizes. The latter is a strong, efficient, and reliable method that shows a clear picture of the continuous model. All the results are validated using numerical simulations in order to better comprehend the dynamics of the disease. The theoretical and numerical findings in this work can be applied as a useful tool for tracking the prevalence of HBV infectious disease.","PeriodicalId":137307,"journal":{"name":"Scientific Inquiry and Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121722830","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}

Its prevalence is 52% in Pakistani women and the rate of infertility is gradually increasing. It can be treated through early diagnosis, management of symptoms, and a healthy lifestyle. This cross-sectional study aimed to determine the level of awareness and knowledge regarding PCOS in the women of Punjab, Pakistan. For this purpose, a total of 350 women between the ages of 16 and 50 years were included in the current study. data was obtained through a questionnaire and analyzed through SPSS (version 25). The results determined that 56% of women were found to have the knowledge of PCOS, while 44% had never heard about it. Furthermore, about 67% of 196 PCOS-aware women were unaware of its signs and symptoms. Moreover, in 14% of the cases, a friend was the source of knowledge regarding PCOS. Whereas, approximately 10% of these women had heard about the syndrome through education, 9% through their family, 7% through various media such as newspapers, television, and social media, and 17% through other sources including general physicians and gynecologists. It was concluded that only 33% of the participants who claimed to have heard of PCOS were aware of its symptoms, whereas 67% were unaware of them. A total of 152 women, out of 350, had never heard about PCOS.","PeriodicalId":137307,"journal":{"name":"Scientific Inquiry and Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133818283","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}

Bioplastics emerged as a suitable replacement and proved more environment friendly than traditional plastics. Among bioplastics, polyhydroxyalkanoates (PHA) proved to be in demand due to their promising properties such as high rate of biodegradability. Three key genes (phaA, phaB, and phaC) are involved in the biosynthesis of PHA. An analysis based on bioinformatics approaches was performed in this study to analyze these key genes and their translated proteins in potential PHA producing microorganisms found on the Gen-solution database. The sequences (DNA and Protein) obtained from PHA producing microorganisms were analyzed in MEGA X to check their evolutionary history. The arrangement of genes was highly diverse. The PHA biosynthetic genes belonging to Proteobacteria showed promising phylogenetic relationship and the occurrence and their distribution in these organisms suggested that a single gene cluster related to PHA might have been segmented in the form of small groups of genes and got transferred among various organisms. The results indicated that the gene and protein sequences were not fully conserved suggesting that the genes had undergone addition, deletion or replacement of nucleotides resulting in gene rearrangement. However, the function of the proteins remained fully conserved suggesting that the protein function had the highest level of conservation and the gene sequences had the least level of conservation according to this study. Overall, the results were a strong indicative that horizontal gene transfer had a strong influence on the distribution and molecular evolution of these PHA biosynthetic genes.","PeriodicalId":137307,"journal":{"name":"Scientific Inquiry and Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121267055","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}

Accordingly, three binuclear Zn(II)-Schiff bases complexes ZnLa - ZnLc were prepared by direct reaction of the ligands La-Lc with Zn(II) ions in equimolar ratios bearing salicyldehydes with OH, NO2 and Cl functional groups. The synthesized compounds ZnLa - ZnLc were evaulated against Gram positive (Enterococcus faecalis NCIMB 13280, Streptococcus mutant ATCC 25175™ and Staphylococcus aureus ATCC 6538™) and gram negative (Escheria coli NCTC 12900, Salmonella typhi and Pseudomonas aeruginosa ATCC 15442) bacterial strains, respectively, by agar well diffusion and broth microdilution techniques. The minimum inhibitory concentration (MIC90) values were calculated by microplate reader at 550 nm to optimum result. It was found that all the synthesized compounds showed promising antibacterial activity against the genus Streptococcus mutant followed Staphylococcus aureus and Escheria coli. Binuclear Zn(II) complexes had a superior antibacterial activity compared to their parent Schiff base ligands. In general, 3,4-dihydroxy derived Schiff bases alongwith their relevant complexes exhibited magnificent antibacterial activity and hence merits to be established as promising keystone for subsequent antimicrobial drug advancement.","PeriodicalId":137307,"journal":{"name":"Scientific Inquiry and Review","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126428620","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}
