On the other hand, primary hyperthyroidism is one of the most common disorders of the endocrine system. Therefore, we aimed to investigate the differences between outcomes of drug therapy with Methimazole & Propylthiouracil (PTU), radioactive Iodine therapy, and surgical procedures as the three most common therapeutic options for primary hyperthyroidism- in patients with Graves' disease, toxic thyroid adenoma, and Toxic Multi Nodular Goiter (TMNG). Methods: This observational study was performed prospectively, and after applying the exclusion criteria, 316 patients with a definite diagnosis of TNMG, toxic adenoma, or Graves' disease, remained in the study. For each patient, one of the therapeutic methods of administration of anti-thyroid drugs, the use of radioactive Iodine, or the use of thyroid surgery was chosen and applied, and during the study period, all patients were followed and evaluated. Results: In this study, 316 patients with primary hyperthyroidism were evaluated, of which 238 (75.31%) patients had Graves' disease, 23 (7.27%) patients had toxic adenoma, and 55 (17.40%) patients had TNMG. The symptoms of thyrotoxicosis syndrome were more common in Graves' disease than in other groups. In this study, 63.82% of drug takers, 20.90% of radioactive Iodine receivers, and 5.26% of patients who had gone under surgery became euthyroid. In addition, 83.27% of drug consumers did not have any side effects. Most patients receiving radioactive Iodine and surgical procedures developed hypothyroidism after treatment, while only 1.70% of those taking anti-thyroid drugs developed this complication. Nevertheless, the failure rate in the drug therapy was highest among all three methods by a percentage of 34.47%. Conclusion: This study suggests a prominent role of drug therapy in the treatment of patients with Graves' disease and TMNG, and in contrast, reduces the role of radioactive Iodine in the treatment of these diseases. However, it is difficult to comment on the treatment of toxic thyroid adenoma based on the findings of this study.","PeriodicalId":36500,"journal":{"name":"Biomedical and Biotechnology Research Journal","volume":"6 1","pages":"569 - 575"},"PeriodicalIF":1.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45034026","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 was aimed to investigate the relationship of lipid levels and ratios at the time of diagnosis to the prognosis prediction of lung cancer. Methods: Sociodemographic and disease-related clinical characteristics of 92 patients diagnosed with lung cancer were reviewed retrospectively. Patients with available lipid parameters at the time of diagnosis were evaluated. Hemogram parameters of the patients included in the study, creatinine and estimated glomerular filtration rate, alanine aminotransferase level, albumin level, C-reactive protein level, as well as total cholesterol (TC)/high-density cholesterol (HDL) ratio, non-HDL/HDL ratio, low-density lipoprotein/HDL ratio, and triglyceride/HDL ratios were examined. Results: The mean age at presentation was 64.2 ± 9.1 years. The distribution of lung cancers is 6 (6.5%) for small cell lung cancer (SCLC) and 86 (93.5%) for non-SCLC. The median follow-up period of the patients is 12 months. During the follow-up, 63 (68.5%) of the patients died. In the univariate analysis, increased non-HDL/HDL ratio was related to mortality. In multivariate analysis, disease stage, albumin level, and TC level were found to be variables affecting the mortality. Conclusion: TC levels at the time of diagnosis can be a guide in determining the prognosis. More experimental studies are needed to elucidate the relationship between the lipid metabolism and lung cancer etiology and to determine the role of lipid levels and ratios in prognosis prediction.","PeriodicalId":36500,"journal":{"name":"Biomedical and Biotechnology Research Journal","volume":"6 1","pages":"556 - 562"},"PeriodicalIF":1.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48262689","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}

This work, therefore, investigated parasitic infections among pupils in Kwara Senatorial Districts for useful information for preventive healthcare. Methods: Stool, urine, and blood samples of 638 subjects (Kwara Central: 152; Kwara South: 263 and Kwara North: 223) were examined for parasites using concentration techniques, Giemsa staining, and microscopy. Results: The results obtained showed the overall prevalence of pupils infected with parasites in Kwara state was 17.9% (114/638). The result obtained in Kwara Central indicated that 15.1% (23/152) of the pupils were infected with parasites. In Kwara South, 2.66% (7/263) of the pupils were infected with parasites. In Kwara North, 37.7% (84/223) were infected with parasites. Distribution of parasitic infection in primary school pupils in Kwara State was: 60.5% (69) Ascaris Lumbricoides; 12.2% (14) Schistosoma mansoni; 8.8% (10) Hookworm; 9.7% (11) Entamoeba histolytica; 4.4% (5) Fassiola gigantical; 2.6% (3) Plasmodium spp., and 1.8% (2) Schistosoma haematobium. The distribution of parasitic infections among the pupils based on age included: 0% (0) (1–5 years). 55.3% (63) (6–10 years) 43.8% (50) (11–15 years), and 0.9% (1) (16–20 years). Conclusion: The parasitic infections among pupils in Kwara Senatorial Districts were lower than the prevalence earlier reported, possibly due to the intervention of donor agents and health promotion. The infection also varied across the three Kwara State Senatorial districts and age categories which might be due to the level of hygiene, degree of intervention, practices, accessibility to portable water, and health facilities.","PeriodicalId":36500,"journal":{"name":"Biomedical and Biotechnology Research Journal","volume":"6 1","pages":"489 - 493"},"PeriodicalIF":1.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45277872","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}

Omicron (B.1.1.529) is the third variant of concern (VOC) that has emerged now in the COVID-19 pandemic after the Alpha (B.1.1.7) VOC (first reported in the UK in December 2020, followed by Delta (B.1.617.2) in mid-2021 in India). Omicron variant was emerged in South Africa and has now found in several countries. Methods: The spread of variants cannot be stopped because countries of the world are connected. This new variant can evade COVID-19 vaccine response and is highly transmissible because Omicron is differing from other variants in many aspects. Omicron has more mutations as compared to Alpha and Delta variants of SARS-CoV-2. Results: It was detected early on a global scale relative to other variants. The more opportunities viruses have to spread, the more it will replicate, the more opportunities virus has to undergo mutations, and create new variants. Omicron may not be horrible and serious as compared to Delta, but its early detection could prevent people. Omicron is an upper respiratory infection, whereas Delta resides in lower respiratory tract. Spread of Omicron is fast, but nothing can say about its severity because there is not much information available on Omicron. Conclusions: Currently, scientists and epidemiologists are working tirelessly together to find out what Omicron can do. This article explains genome structure of SARS-CoV-2, its pathogenesis, global upsurge, devastation, and future prospect.","PeriodicalId":36500,"journal":{"name":"Biomedical and Biotechnology Research Journal","volume":"6 1","pages":"594 - 597"},"PeriodicalIF":1.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45779668","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}

Moreover, the use of experimental in vitro and in vivo approaches in search for potent drug candidates is costly and time-consuming. The aim of this study was to evaluate the pharmacological properties of some reported phytoconstituents of Ageratum conyzoides against key enzymes of B. dermatitidis using in silico approach. Methods: A total of 29 reported bioactive compounds previously isolated from the leaves of A. conyzoides were randomly selected by a literature survey and their 3D Structure Data File (SDF) structures were downloaded from PubChem database. Applying molecular docking and dynamics simulation techniques, the phytoconstituents (ligands) were docked with the binding ligand pocket of three simulated enzymes; Saccharomyces cerevisiae lanosterol 14-alpha demethylase, human squalene epoxidase, and thymidylate synthase from Pneumocystis carinii using AutoDock 4.0 software and the poses that showed lowest binding energies were visualized using LigPlot+. Results: The results obtained from the docking studies of the selected phytoconstituents in A. conyzoides leaves showed that 4 out of the 29 ligands (sitosterol, catechin, stigmasterol, and 5-benzamido-4-oxo-6-phenylhexanoic acid) interacted with and showed very good binding affinity toward the 3 crucial antifungal drug target receptors, and exhibited significant inhibition compared to the standard drugs. Conclusion: Therefore, sitosterol, catechin, stigmasterol, and 5-benzamido-4-oxo-6-phenylhexanoic acid from A. conyzoides leaves hold a promising potential to be explored for their antifungal activities.","PeriodicalId":36500,"journal":{"name":"Biomedical and Biotechnology Research Journal","volume":"6 1","pages":"501 - 509"},"PeriodicalIF":1.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44400558","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}
