The existing approach for liquid biopsy is to utilize microfluidic chips for the isolation of circulating tumor cells (CTCs) or exosomes or extracellular vesicles (EV) from patient samples, and then for the analysis of the cargo contained inside the CTCs, exosomes or EVs. However, such an analysis does not provide a real-time liquid biopsy, since there is a long delay between the time of sample collection and the results from the analysis. Microfluidic chip-formats also provide the capability to mimic tissue functions from the analysis of small numbers of cells cultured in the chip. Analysis of the secreted molecules from such cells could provide a measurement of the secretome, which could be analogous to a liquid biopsy. A 3D structural organization of cells in microfluidic chips is usually in the form of organoids or spheroids. The analysis of organoids or spheroids is well-adapted for immunohistochemistry or ELISA-type identification of surface markers, but not for real-time analysis of secreted molecules since the fluid and molecules in the interior volume of the organoid or spheroid is not accessible in real-time. We have recently proposed an alternative novel design for a microfluidic chip format comprising 3D micro-niches that provide a real-time analysis of secretions produced directly from small numbers of cells. The microfluidic chip with 3D micro-niches then analyses the secretions from these monolayers in real-time (“secretome”). The microfluidic chip includes electronic biosensors that provide real-time measurement of secreted molecules. This short review concludes with a proposition for the means to utilize this novel microfluidic chip to function as a real-time and quantifiable diagnostic screening device to differentiate cancerous cells from healthy cells.","PeriodicalId":22379,"journal":{"name":"The EuroBiotech Journal","volume":"207 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135707860","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}

Tripathy","doi":"10.2478/ebtj-2023-0012","DOIUrl":"https://doi.org/10.2478/ebtj-2023-0012","url":null,"abstract":"Abstract Obsessive-Compulsive Disorder (OCD) is a psychiatric illness that produces significant psychological distress in patients. Individuals with OCD have recurring unwanted thoughts or sensations which make them obsessed with something and feel to do something repetitively as a compulsion. In general detection of OCD is performed by symptoms analysis. However, the symptoms are significantly visible at a later stage. Even individuals with OCD have less faith in the analysis of the symptoms as long as it is not affecting their life negatively. As a result, they start their treatment at a later stage and the treatment process becomes longer. However, it is observed that if the detection is performed through laboratory analysis through some biomarkers then the patients have more faith in the detection process and can start their treatment well in advance. Therefore laboratory detection of OCD can play a vital role in OCD treatment effectiveness. Most of the laboratory detection process proposed in the literature uses Machine Learning on related biomarkers. However, the prediction accuracy rate is not enough. This research aims to analyze the approaches to pediatric OCD based on machine learning using neuroimaging biomarkers and oxidative stress biomarkers. The challenges in OCD detection and prediction using neuroimaging biomarkers, oxidative stress biomarkers, and Machine Learning models have been described. Further, it analyzes the performance of different machine learning models that were used for OCD detection and highlights the research gap to improve prediction accuracy.","PeriodicalId":22379,"journal":{"name":"The EuroBiotech Journal","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135708016","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 splicing construct assay has double reporters for intron 2 splicing in chloride channel (CLCN1). The CLCN1 transgene splicing construct assay was used to transfect wild type and DM fibroblast cell lines and the clones generated showed that it enabled quantification of splicing efficiency in transgene construct. Validation of the DM fibroblasts containing transgene splicing construct was performed by differentiating the DM fibroblasts into myoblasts which exhibited a switch in CLCN1 splicing construct which was consistent with that associated with myotonic dystrophy (DM) condition. The myoblast derived from fibroblasts cell-based gene-splicing assay was subsequently applied in therapeutic screening in small throughput screens of 113 compounds which identified Protein Kinase C inhibitors- hypericin and Ro-31-8220 as potential therapeutic agents. The CLCN1 gene-splicing assay is a good model system for application in therapeutic screening in myotonic dystrophy because its double reporters facilitated quantification of effect putative drug on correction of misregulated splicing.","PeriodicalId":22379,"journal":{"name":"The EuroBiotech Journal","volume":"7 1","pages":"155 - 164"},"PeriodicalIF":1.7,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48008108","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 microstructure surface and crystallographic structure stability of the formed multiwall carbon-based nanotubes-chitosan obtained at formed multiwall carbon-based nanotubes per chitosan ratios of 1:1, 2:1, 3:1, and 4:1 were examined via field emission scanning electron microscopy, X-ray radiation, Raman spectroscopy, surface area and pore size, and thermogravimetric analyses. Homocysteine solutions at 30–100 µM were measured by cyclic voltammetry using the different formed multiwall carbon-based nanotubes-chitosan compositions as sensor electrodes. That with an optimal formed multiwall carbon-based nanotubes per chitosan ratio of 4:1 showed the highest crystallinity and electrical conductivity and gave a high coefficient of determination (R2 = 0.9036) between the homocysteine concentration and the oxidation current detection over an operating range of 30–100 µM. This new composite microelectrode for detecting homocysteine concentration makes it a promising candidate for clinical applications.","PeriodicalId":22379,"journal":{"name":"The EuroBiotech Journal","volume":"7 1","pages":"144 - 154"},"PeriodicalIF":1.7,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47943351","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}
