{"title":"EfficientNet - XGBoost: An Effective White-Blood-Cell Segmentation and Classification Framework","authors":"Bairaboina Sai Samba SivaRao, B. S. Rao","doi":"10.26599/nbe.2023.9290014","DOIUrl":"https://doi.org/10.26599/nbe.2023.9290014","url":null,"abstract":"In the human body, white blood cells (WBCs) are crucial immune cells that help in the early detection of a variety of illnesses. Determination of the number of WBCs can be used to diagnose conditions such as hematological, immunological, and autoimmune diseases, as well as AIDS and leukemia. However, the conventional method of classifying and counting WBCs is time-consuming, laborious, and potentially erroneous. Therefore, this paper presents a computer-assisted automated method for recognizing and detecting WBC categories from blood images. Initially, the blood cell image is preprocessed and then segmented using an effective deep learning architecture called SegNet. Then, the important features are devised and extracted using the EfficientNet architecture. Finally, the WBCs are categorized into four different types using the XGBoost classifier: neutrophils, eosinophils, monocytes, and lymphocytes. The advantages of SegNet, EfficientNet, and XGBoost make the proposed model more robust and achieve a more efficient classification of the WBCs. The BCCD dataset is used to evaluate the performance of the proposed methodology, and the findings are compared to existing state-of-the-art approaches based on accuracy, precision, sensitivity, specificity, and F1-score. Evaluation results show that the proposed approach has a higher rank-1 accuracy of 99.02% and outperformed other existing techniques.","PeriodicalId":18971,"journal":{"name":"Nano Biomedicine and Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47604991","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}

Kotakadi","doi":"10.26599/nbe.2023.9290012","DOIUrl":"https://doi.org/10.26599/nbe.2023.9290012","url":null,"abstract":"This study was conducted to identify promising applications of green silver nanoparticles (AgNPs) prepared from a bark extract of Sweetinia mahagoni (Sm). The green synthesized Sm-AgNPs were characterized using various spectroscopy methods. AgNPs were first investigated using ultraviolet–visible spectroscopy, and the metal nanoparticles exhibited an intense surfaceplasmon resonance (SPR) peak at different wavelengths. The green synthesized Sm-AgNPs had an SPR peak at 430 nm, which confirms the formation of Sm-AgNPs. In addition, Fourier transform infrared (FTIR) spectroscopy was conducted to determine the bioactive compounds of bark extract that actively participate in the reduction of Sm-AgNPs, and the results revealed O−H stretching of free hydroxyl alcohol and phenols, N−H bonds of primary amines, S ＝ O stretching of sulfoxide in aromatic groups, C−I stretching due to aliphatic iodo compounds, and C−Br stretching by halo compounds of the bark extract which might reduce and stabilize Sm-AgNPs. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) results revealed that Sm-AgNPs were approximately irregular spheres. EDS results revealed the complete reduction of silver to elemental silver. The particle size analysis of Sm-AgNPs was conducted using dynamic light scattering (DLS), and the results revealed that Sm-AgNPs were polydisperse with an average size range from 35.8 to 47.8 nm, an average mean size of 41.3 nm, and a Z average of 37.7 nm. Sm-AgNPs had a negative zeta potential value of −19.0 mV, indicating that Sm-AgNPs were very stable in colloidal form. Further studies were carried out to demonstrate their usefulness in industrial and biomedical applications. In these studies, Sm-AgNPs exhibited a very good antibacterial activity against both Gram-negative and Gram-positive bacteria. In addition to regular assays, we also investigated important industrial applications such as the reduction of toxic hexavalent chromium to a nontoxic form and sensing of Hg 2+ ions. The results revealed that Sm-AgNPs had an excellent performance in biosensor applications such as sensing and detecting mercury at parts per million/parts per billion levels. In conclusion, green Sm-AgNPs are promising materials in therapeutic and industrial applications.","PeriodicalId":18971,"journal":{"name":"Nano Biomedicine and Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43849641","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}

Pijitrojana","doi":"10.26599/nbe.2023.9290009","DOIUrl":"https://doi.org/10.26599/nbe.2023.9290009","url":null,"abstract":"Kidney disease, as a global health problem, can progress to kidney failure. Kidney transplantation is a treatment option for end-stage disease and an alternative to dialysis. Complement-dependent cytotoxicity tests and flow cytometry are methods used to test for compatibility between autoantibodies and donor recipient. Antibodies against donor human leukocyte antigens (HLAs), linked to hyperacute or severely acute rejection, frequently result in graft loss. Currently, fluorescent bead assay (Luminex ® ) technology is used in Thailand for HLA–antibody typing tests. However, each test requires specific location and time, expensive equipment, and high costs. The goal of such research is that, HLA–antibody typing tests can be performed wherever it is the most convenient for recipients and hospitals. A further advantage is that the surgeon can perform a final test for confirmation before the surgery. Numerous technologies are currently available for this purpose. The focus of this study was on the Fe 3 O 4 magnetic nanoparticles (MNPs) immobilized with HLAs frequently found in the Thai population. These were examined using nuclear magnetic resonance (NMR) to measure HLA antibody typing. MNPs have recently attracted considerable attention because of their strong magnetization and large surface areas. Immobilization reactions with antigens and the straightforward magnetic separation of MNPs are low-cost techniques. Hence, the commercialization of Fe 3 O 4 MNPs is favorable. In this study, MNPs were functionalized with 3-aminopropyl triethoxysilane (APTES) in toluene and ethanol, and the nanoparticles were streptavidin activated after APTES treatment. A specific biotinylated HLA for the Thai population was used and immobilized on streptavidin. The MNPs were effectively immobilized. The magnetic properties can be modified by adding other ions to Fe 3 O 4 . We discovered that the shape and size variations of Fe 3 O 4 MNPs may have an impact on the amount of functionalized and immobilized surface area.","PeriodicalId":18971,"journal":{"name":"Nano Biomedicine and Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47184081","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}

We had previously demonstrated that the multivitamin (C, D3, and B12)–cisplatin nanoparticle complex—NanoCisVital (NCV)— could alleviate chemotherapy-induced cancer fatigue. Chitosan is frequently used in functional nanomaterials to encapsulate drugs, because it is biodegradable, biocompatible, and non-toxic. The chitosan-based NCVs were prepared, and their physicochemical properties, size, and stability were evaluated before assessing their effect on cancer cell lines. The multivitamin mixture is packed in the core, and cisplatin is loaded at the periphery of the nanoparticle. This encapsulation facilitates the slow and sequential release of peripheral cisplatin and the core multivitamin combination. By increasing the amounts of vitamin and drug-encapsulated nanoparticles in breast and cervical cancer cell lines, the viable cell percentage was calculated. DDX3X promotes cancer cell proliferation, invasion, and metastasis, while Ki-67 promotes active cell proliferation in all cell types. DDX3X is elevated in several cancer types, and breast cancer cells express it abnormally. The Ki-67 protein is a biomarker of cell proliferation that is present throughout all active stages of the cell cycle but undetectable in the resting state. The expression of the DDX3X and Ki-67 genes is altered in NCV-treated cells. This study uses DDX3X and Ki-67 gene expression as a comparative measuring tool for the anti-cancer and cell proliferation effects of cisplatin and vitamins, respectively.","PeriodicalId":18971,"journal":{"name":"Nano Biomedicine and Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46388916","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}

Selenium nanoparticles (SeNPs) have been reported to exhibit an inhibitory effect on cancerous cells. The aim of the present study was to use the drug delivery systems poly(lactic-co-glycolic acid) (PLGA) and poly(lactic-co-glycolic acid-poly(ethylene glycol)-folic acid (PLGA-PEG-FA) to encapsulate SeNPs and investigate their antineoplastic effects against two cell line types (MCF-7 as a positive folate receptor and HBL as a negative folate receptor) by exploiting overexpression features in some types of cancer cells to ensure delivery of drug molecules at high dosages toward targeted cells and circumvent normal cells/tissues. SeNPs were chemically synthesized and characterized with dynamic light scattering (DLS) and transmission electronic microscopy (TEM). The cytotoxicity of both nanomaterials was evaluated against MCF-7 and HBL cells by using the methyl thiazolyl tetrazolium (MTT) assay which showed a high cytotoxic effect against MCF-7 cells with a lesser effect against HBL cells. Additionally, an apoptosis assay was also performed by using acridine orange/ethidium bromide dual staining, and the antioxidant effect was also investigated by using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) colorimetric method with high antioxidant potential for both formulations. They showed nonhemolytic activity on human red blood cells. This work could be considered promising for pharmaceutical formulation.","PeriodicalId":18971,"journal":{"name":"Nano Biomedicine and Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48154550","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}
