The SARS-CoV-2 variants, Delta and Omicron, posed an additional challenge in the management of these patients because of their virulence and high transmissibility. Objective: To assess the disturbance of certain biomarkers in COVID-19-positive T2DM patients in Pointe-Noire. Methods: We performed a descriptive cross-sectional study on a cohort of 206 type 2 diabetic patients affected by COVID-19. Blood samples were taken for analysis of biomarkers (CBC, ESR, CRP, GLY, and HbA1c, lipid profile, urea and creatinine). RNA was extracted from nasopharyngeal samples and PCR was performed to determine the presence of Delta and Omicron variants. Results: The mean age of our patients was 56.33 ± 12 years. The Delta variant was the most common 132 (64.08%), followed by the other variants 57 (27.67%) and Omicron 17 (8.25%). We observed significant disturbances (p<0.05) in biomarkers as a function of Delta and Omicron variants concerning: TC, TG, HDL, LDL, DDI, VS, CRP, GLY, and HbA1c. Conclusion: We identified the Delta variant as the most frequent in the diabetic population studied. Almost all biological markers studied were disrupted during COVID-19 infection in the type 2 diabetic population.","PeriodicalId":164482,"journal":{"name":"EAS Journal of Biotechnology and Genetics","volume":"52 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141008315","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}

Results: Primary liver cancer was more prevalent in younger individuals while metastatic cancer dominated in older age groups. Certain areas exhibited higher primary cancer rates than others. Provisional diagnoses varied by occupation and location. Male patients presented with more advanced stages and distant metastasis compared to females. Conclusions: Geographical and occupational disparities exist in liver cancer profiles. Sex differences were observed in disease presentation. Robust studies are needed to establish causal relationships and explore underlying disease mechanisms.

After harvesting and allantoic fluid collection, RNA extraction was done and cDNA synthesis and RT-PCR were performed. After infection of the chick embryo with MDR Pseudomonas aeruginosa, both IL-10 and IFN-Ƴ gene expressions were increased, but in the curative sets those were challenged with Bakreswar hot spring water IL-10 and IFN- γ both gene expressions were decreased.

Material and Methods: We studied semens of three hundred and forty-four (344) congolese men affected by infertility.

Medical history highligts mostly the notion of chronic infection, varicoceles and surgery of the genital tract. The most identified sperm abnormalities were moderate asthenozoospermia followed by severe oligoasthenozoospermia and azoospermia. Conclusion: The prevalence shows that male infertility is not rare in Brazzaville.

The main objective of this study is to evaluate the antimicrobial activities of this plant extract. One significant use of plant extracts can be in treating bacterial infections and develop potential antibacterial agents against multi drug resistant (MDR) and susceptible bacteria. If antimicrobial activities are present, these extracts will provide useful information for discovering new compounds with better activity and more effectiveness against resistant and susceptible bacteria responsible for infections than currently available. The ethanolic extract of leaves of Holarrhena pubescens was prepared and tested against multidrug resistant (MDR) and American type culture collection strains of bacteria. We have obtained two types of results in this experiment. The extract showed antimicrobial properties against Staphylococcus aureus (ATCC 23235), Escherichia coli (MDR) and Acinetobacter (MDR), while, it showed no antimicrobial activities along with some growth promoting role against Escherichia coli (ATCC 25922), and Klebsialla pneumoniae (MDR), which may be due to chemicals other than secondary metabolites.","PeriodicalId":164482,"journal":{"name":"EAS Journal of Biotechnology and Genetics","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127542615","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}

Thus, in this study, we aim to assess the effectiveness of the ethanolic extract of the flowers of Avicennia marina, a commonly found mangrove species in coastal regions, against multi-drug resistant (MDR) microorganisms. The study focused on evaluating the extract's antibacterial activity against Staphylococcus aureus (ATCC 29213), Escherichia coli (ATCC 25922), Escherichia coli (MDR), Klebsiella sp.

The results of the study demonstrated that the flower extracts of Avicennia marina exhibited noteworthy antimicrobial properties against all the tested MDR microorganisms. The plant contains several bioactive compounds, such as flavonoids, tannins, and alkaloids, which are believed to contribute to the observed antimicrobial effects. These findings indicate that Avicennia marina flowers could serve as a valuable natural source for developing antimicrobial agents that could combat drug-resistant bacterial infections. However, future studies should focus on evaluating the efficacy and safety of this extract in live organisms (in vivo) to determine its potential as a new drug for treating resistant infections.","PeriodicalId":164482,"journal":{"name":"EAS Journal of Biotechnology and Genetics","volume":"181 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121271094","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 cultivation of stevia in Malaysia is hampered because- it produces flowers at an early stage under Malaysia's photoperiod condition, thus leading to poor leaf yield for sweetener extraction. Additionally, there has been low breeding work for suitable cultivars. Thus, the impact of Gama irradiation in developing new Stevia mutants was studied. Seeds of MS012 were collected and exposed to gamma irradiation using a gamma cell in UKM, Malaysia to determine the LD50. The seeds were packed into 21 parts; one part served as the control and the others were subjected to varying gamma irradiation grays of 100 to 2000 grays. Irradiated seeds were sown for germination under the red light for 15 days. The LD50 was determined by plotting a simple regression graph of plant height against irradiation grays. Results revealed LD50 was 55 grays. The number of germinated seeds differed with respect to doses. Genetic analysis showed four types of chlorophyll mutants were induced: Albina, Chlorina, Xantha and Xantha-Viridis. Frequency and spectrum analysis revealed that Chlorina has the highest occurrence at 33.03%. Two classical novelties: (i) M1RAAMBO/03, and (ii) M2 RAAMBO/04 were developed.","PeriodicalId":164482,"journal":{"name":"EAS Journal of Biotechnology and Genetics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116641329","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}
