For the purpose of researching the development of the B-cell repertoire and the development of self-tolerance, these early B-cell precursors are of utmost importance. The genetic and/or microenvironmental variables that control the beginning of immunoglobulin synthesis in embryonic haemopoietic cells are, however, poorly understood. Purpose: The ontogeny of B-cell precursors in chicken embryos from day three of incubation was examined in this work. Research methods: The terms \"ontogeny, B-cell, precursors, chicken embryos, incubation\" were used in a thorough literature search in the PubMed, NCBI, and Google Scholar databases. After all articles were picked based on the inclusion and exclusion criteria, 38 papers that satisfied the criteria for inclusion were collected. Result: The study's findings show that clglarge basophilic hemopoietic stem cells and cIg+ small lymphoid B-cell precursors are two types of migrant cells that appear to enter the embryonic bursa of Fabricius. Hence, B lymphopoiesis does not only take place in the bursa of Fabricius in the avian embryo. Although the yolk sac and the hemopoietic tissues around the dorsal aorta are strong candidates, the identity of the extra-bursal location remains unknown. Conclusion: Hence, general haemopoietic organs may serve as the initial site of B lymphopoiesis in both birds and mammals. Only later in the course of avian development do the bursal follicles become accessible and take over.","PeriodicalId":9054,"journal":{"name":"Biomedical and Pharmacology Journal","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135032101","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 synthetic thrombolytic agents such as streptokinase, urokinase and antistreplase have their own side effects. Plants are always considered as safe and cost-effective therapeutic agents. Dietary therapeutics is an emerging branch for the prevention and treatment of several ailments. The present article compiles 43 edible plants which have shown in vitro thrombolytic potential and are also employed in the diets of several ethnic communities in India. Among these, Bauhinia purpurea and Baccaurea ramiflora are two plants having more than 70% in vitro clot lysis potential; Coccinia grandis, Curcuma longa, Cyperus rotundus, and Typha domingensis have 50-70% thrombolytic activity; and the rest of the plants have 11-49% thrombolytic activity. These 43 plants also include spices and condiments such as Turmeric, Black pepper, Indian Bayleaf, Coriander and Ginger, which affirms the traditional saying of using food as medicine. Besides, these edible plants also possess various phyto-constituents and health-beneficial pharmacological activities. If these plants could be incorporated into a routine diet, it might be possible to prevent or delay the onset of CVD. However, detailed studies are required to evaluate the pattern of CVD in ethnic communities consuming such plants, as well as systematic clinical trials are warranted to investigate the thrombolytic efficacy of these plants.","PeriodicalId":9054,"journal":{"name":"Biomedical and Pharmacology Journal","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135032385","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 objective of this study is to present a succinct overview of the existing literature, while also elucidating the development of the disease in respect to contemporary instances, possible therapeutic approaches, and strategies for preventing infection. To date, a total of 12,261 occurrences have been recorded over a wide range of 76 nations. Monkeypox is a zoonotic disease that has previously been limited to endemic areas in Western and Central Africa. However, there have been isolated outbreaks in other countries, including the United States, that have been linked to the importation of wild animals from Ghana and other affected areas. The current outbreak has seen a significant shift, with human-to-human transmission surpassing all other modes of transmission. This development has raised concerns regarding the potential extension of the outbreak within communities, particularly in cases that may have gone unreported. The observed results may be attributed to the increase in human-to-human transmission subsequent to the cessation of smallpox vaccination, which provided partial immunity against monkeypox. The occurrence of outbreaks beyond the African continent underscores the worldwide importance of the illness. The demographic that exhibits the highest vulnerability to infection is young males who engage in sexual activity with other males. While the existing understanding suggests that the clinical progression of the disease is very moderate, there remain several unresolved inquiries that necessitate additional investigation. These include the possibility of a genital reservoir of the virus in humans and the possibility of airborne transmission.","PeriodicalId":9054,"journal":{"name":"Biomedical and Pharmacology Journal","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135032390","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}

Betatrophin, a liver or adipocyte-derived hormone, was assumed to improve islet insulin secretion and compensate insulin resistance but its level during obesity is still conflicted. This study aimed to explore serum betatrophin level in centrally-obese middle-aged men with diabetic potentials compared with age-matched non-obese ones. Sixty-eight male subjects of 40-60 years of age, residing in North Okkalapa Township, Yangon, Myanmar, were recruited and classified into centrally-obese group (n=34) and non-obese group (n=34). Fasting blood samples were obtained to quantify plasma glucose by glucose oxidase method, and serum insulin and betatrophin levels by ELISA. Plasma glucose levels were comparable between the two groups, while insulin concentration of obese group was significantly greater than that of non-obese group. Therefore, HOMA-IR was markedly increased in obese subjects when compared to non-obese ones (4.87±0.28 vs 1.90±0.14, p<0.001) and so did HOMA-β (310.88±26.58 vs 149.00±11.83, p<0.001). Interestingly, betatrophin hormone level was significantly reduced in obese group than non-obese group (1.72±0.21 vs 2.72±0.26 ng/ml, p<0.01). Moreover, betatrophin had a strong negative correlation with glucose and insulin levels (p<0.05) as well as with the indicator of central adiposity, waist circumference (p<0.05), among the subjects. However, significant correlation between betatrophin and HOMA-IR and HOMA-β was not observed in both groups (p=0.14 and 0.20 respectively). Taken together, betatrophin hormone has been found to decrease in adult central obesity, which is noticeably associated with insulin resistance and compensatory beta-cell hyperfunction. Betatrophin, previously regarded as beta-cell mitogen, has been denied in this study, owing to lack of correlation with HOMA indexes of diabetes.","PeriodicalId":9054,"journal":{"name":"Biomedical and Pharmacology Journal","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135032690","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 global prevalence of the disease is gradually growing. In all leading countries, it is one of the senior citizens' leading causes of death. So, much research shows that early detection of illness is the most critical factor in improving patient care and treatment outcomes. Currently, AD is diagnosed by the manual study of magnetic resonance imaging, biomarker tests, and cognitive tests. Machine learning algorithms are used for automatic diagnosis. However, they have certain limits in terms of accuracy. Another issue is that models trained on class-unbalanced datasets often have poor results. Therefore, the main objective of the proposed work is to include a pre-processing method before the hybrid model to improve classification accuracy. This research presents a hybrid model based on a deep learning approach to detect Alzheimer’s disease. Which, we are using the SMOTE method to equally distribute the classes to prevent the issue of class imbalance. The hybrid model uses Inception V3 and Resnet50 to detect characteristics of Alzheimer's disease from magnetic resonance imaging. Finally, a dense layer of convolution neural network is used for classification. The hybrid approach achieves 99% accuracy in classifying MRI datasets, which is better than the old work. These results are better than existing approaches based on accuracy, specificity, sensitivity, and other characteristics.","PeriodicalId":9054,"journal":{"name":"Biomedical and Pharmacology Journal","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135031876","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}

Extraction of active antibacterial compounds by maceration and partitioning, antibacterial tests were carried out by diffusion method, separation of compounds by column chromatography method, and identification of active fractions using LSMS/MS. The results of maceration of 350 g of Inocarpus fagiferus Fosb stem bark produced 22.97 g of methanol viscous extract which was able to strongly inhibit the growth of S. aureus bacteria (14.75mm) and medium inhibit (8.50 mm) towards E. coli. The partition results of the methanol concentrated extract respectively with n-hexane, chloroform, n-butanol, and water yielded 0.01; 0.01; 2.75, and 0.07 g extracts. Based on extract weight only n-butanol extract allows further separation. The result of antibacterial activity has shown a strong inhibition zone toward S. aureus and E. coli (16.50 mm) and with a minimum inhibitory concentration (MIC) of 5%. The result of separation n-butanol extract by gradient column chromatography (silica gel 60; methanol: chloroform (5:5; 6:4; 7:3; 8:4; 9:1; and 10:0)) yielded 4 fractions (FA, FB, FC, and FD) with FC the most active antibacterial toward S. aureus and E. coli with an inhibition zone 7.25 mm and 6.25 mm respectively at 5%.
