It involved categorizing rats into four groups (n = 6) consisting of the control, benzo(<em>a</em>)pyrene (B[<em>a</em>]P) treated, KP group, and a combination therapy for 30 days. The research focused on the interaction of <em>S.vulcani</em> and (B[<em>a</em>]P) compounds with colorectal signaling, using protein-protein interaction networks, molecular docking and dynamic simulation to assess compound affinity with target proteins. Furthermore, the epitope of colorectal cancer was aligned with the kombucha microorganism to explore the cross-reactivity. The experimental data demonstrated that B[<em>a</em>]P impaired colon histoarchitecture and elevated interleukin1β, whereas KP countered these effects. The study pinpointed key proteins and notable S. vulcani compounds linked to colorectal cancer. Moreover, six epitope candidates of colorectal cancer were obtained which have an identity of 65%–95 % for query coverage with <em>Lactiplantibacillus plantarum</em> and <em>Saccharomyces cerevisiae</em> that bind and fluctuate stability to core regions of HLA- A*0101 and HLA-DRB1*0101.

Few bat species like <em>Rousettus aegyptiacus</em> and <em>Hipposideros caffer</em>, among other members of the <em>Chiroptera</em> order, may serve as a natural reservoir for the virus, which can transmit the disease to humans and other mammals.

The disease carries an extremely high mortality and morbidity rate.

Increased focus on health education, enhancement of laboratory services and facilities, adherence to patient safety protocols, and robust surveillance systems are urgently needed to combat this fatal disease.

These complications encompass pneumonia, eye problems, and secondary-skin infections. Current complications include swelling and sores within the rectum that would result in pain or complexity while urinating. Due to such complexities, it is crucial for monkeypox detection. Concurrently, with the evolvement of AI (Artificial Intelligence) based methods, existing works have tried to perform better detection of monkeypox and non-monkeypox. Nevertheless, these studies have been lagging in accuracy rate. As an enhancement, this study proposes RN-50-ZCA (Residual Network-50-Zero Phase Component Analysis) for feature extraction to attain enhanced classification performance. ZCA-whitening is utilized with RN-50, which assists in accurately identifying the features that agree with the image lesions. This approach incorporates data normalization and later linear transformation that has been considered to support lessening co-variance among the features. This also maintains the concrete variance. To fuse the features, PCA (Principal Component Analysis) is used. Finally, the research proposes MXGBoost (Modified eXtreme Gradient Boosting) based on statistical loss function for classifying monkeypox and non-monkeypox images (other viral samples, chickenpox samples, and smallpox samples) for acquiring effective prediction. Using MXGBoost with the loss function aids in extemporizing the prediction rate of the model by considering certain features of the issues being modelled. With such factors, the proposed loss function can support diminishing overfitting, thereby improvising the generalizability of the model. The performance of this study is assessed by comparison with three studies, and the analytical results exposed the better prediction rate of the proposed system.</p></div>","PeriodicalId":36019,"journal":{"name":"Medicine in Microecology","volume":"19 ","pages":"Article 100098"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590097824000016/pdfft?md5=c83565d2949c199e7b96aa17a7b4a0de&pid=1-s2.0-S2590097824000016-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139457303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the gut microbiota profile in cisplatin-related nephrotoxicity patients has not been fully investigated. Databases were rigorously reviewed for investigations contrasting the gut microbial profiles on effective probiotics against cisplatin-induced nephrotoxicity from 1998 to 2023. Cisplatin's use is often restricted due to adverse effects like nephrotoxicity, ototoxicity, neurotoxicity, and vomiting. Probiotics, or gut microbiota, are crucial for maintaining health and treating diseases, particularly kidney damage. The current study reviewed that patients with cisplatin-induced nephrotoxicity can be protected by using supplementation of probiotics. Scientific research has focused on the active participation of natural supplementation on cisplatin-induced nephrotoxicity issues. Different preclinical studies showed that the probiotics treat cisplatin-induced nephrotoxicity, but further clinical tests are needed for full confirmation.</p></div>","PeriodicalId":36019,"journal":{"name":"Medicine in Microecology","volume":"19 ","pages":"Article 100099"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590097824000028/pdfft?md5=cf0c7bb29d00b06cbd00612cf6f4a769&pid=1-s2.0-S2590097824000028-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139637733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
