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}

For the management of sunitinib-induced hypothyroidism, an evaluation of thyroid hormone and antibody profile is recommended before starting treatment with tyrosine kinase inhibitors. Patients with pre-existing thyroid dysfunction should undergo dose adjustment of L-thyroxine during treatment with tyrosine kinase inhibitors. Thyroid dysfunction is not a reason to discontinue or reduce the dosage of sunitinib. Their occurrence appears to correlate with increased antitumour efficacy of the inhibitor. There are currently no guidelines for monitoring thyroid activity during treatment with TKIs, and the time interval at which TSH should be periodically measured has not yet been determined. A reasonable approach is to monitor thyroid function, both before and during 2-4 weeks after the end of therapy. A comprehensive analysis of adverse events associated with the use of these inhibitors could help clinical monitoring of patients along with the adoption of appropriate management approaches.","PeriodicalId":9054,"journal":{"name":"Biomedical and Pharmacology Journal","volume":"27 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":"135032538","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}

Health literacy, a subset of overall literacy talents, is relatively correlated with it and has been described as the extent to which people can gain, approach, and understand introductory medical information and services required to take health decisions. Concerning HIV, people with low health literacy have less information on the illness and their medical care needs. Moreover, they show poor drug compliance, potentially leading to treatment failure and lack of achievement of the target viral load reduction. The shortfall of non-conceptual models of health literacy is an issue in the utilization of general proficiency instruments. HIV disease-specific health literacy instruments would be more useful and likely to provide more meaningful results rather than those obtained through the use of general instruments. Further exploration of HIV health literacy is demanded. Prospective studies should involve different geographical areas with different socioeconomic characteristics, societal structures and regional healthcare settings. This narrative review has limitations. The vast majority of the HIV research referenced in this study was conducted among the western and African populations with HIV. The studies generally excluded individuals over 50 years of age, restricting the applicability of the study findings.","PeriodicalId":9054,"journal":{"name":"Biomedical and Pharmacology Journal","volume":"37 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":"135031748","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}

Forest honey can reduce corticosteroid levels as a stress response from physical stress induction which is expected to increase reproductive efficiency including folliculogenesis and the formation of the corpus luteum. This study aims to determine the effect of forest honey on rats (Rattus novergicus) exposed to physical stress on corticosteroid levels, folliculogenesis, and the number of corpus luteum. This study is an experimental laboratory one using 32 rats which were divided into 4 treatment groups; control positive (C) treated with physical stress, treatment 1 (T1) treated with physical stress + honey 2 g/rat/day PO, treatment 2 (T2) treated with physical stress + honey 4 g/rat/day PO and treatment 3 (T3) treated with physical stress + honey 6 g/rat/day PO. All treatments were carried out for 14 days. The results showed that T1 had the lowest corticosteroid level compared to all treatment groups and the corticosteroid level of this group was significantly different (p <0.05) compared to that of C and T3. The folliculogenesis profile showed that the number of primary secondary, tertiary, and Graafian follicles of group T1 was significantly different (p<0.05) compared to that of C, T2, and T3. In terms of the number of corpus luteum, it showed that T1 had the highest number of corpus luteum, and the number of corpus luteum in this group was significantly different (p<0.05) from that of C, T2, and T3. It can be concluded that the administration of forest honey at a dose of 2g/rat/day could reduce corticosteroid levels, improve the folliculogenesis profile, and increase the number of corpus luteum in rats exposed to physical stress. The use of forest honey could reduce corticosteroid levels as a stress response from physical stress induction which was expected to increase reproductive efficiency.","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":"135032270","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}

Biocompatible polycationic polymer chitosan is used for nanoformulation development. The aqueous extract loaded chitosan nanoparticle formulation displayed a particle size of 186± 5.37 nm with a polydispersity index of 0.226 and zeta potential value of 23 ± 1.93 mV. The nanoformulations were assessed for its anti-diabetic properties in comparison to aqueous extracts for the first time by in- vivo methodologies. Several parameters like body weight, blood glucose level, blood and serum biomarkers, were examined. Changes in tissue histoarchitecture, liver glycogen content, oxidative stress response and antioxidant status were also studied. In diabetic rats, the nano-scale formulation significantly reduced blood glucose levels, glucose tolerance, lipid profiles, and serum biomarkers, comparable to the oral hypoglycemic medication glibenclamide. The restoration of antioxidant status and pancreatic histoarchitecture through by size assisted delivery may be related to the improved control of diabetes by the nanoformulation than the extract alone.
