Various researches are going on in this field to achieve the desired standard. Natural fiber reinforced polymer composite (NFPC) has a huge affinity to interchange the composite made up of synthetic fiber. This is primarily because of the advantages like light-weight, non-toxic, nonabrasive, easy availability, low cost and biodegradable properties. The specific mechanical properties like specific tensile modulus and other specific properties of natural fiber gives a satisfying result for composites as compared to synthetic fiber based composites. The general objective of this work was to develop a composite from bamboo fibers and HDPE reinforced with red bauxite mud residues to ensure good thermal stability and improve the physico-mechanical properties in traction and flexion. The morphology of the composites showed that there was a homogenous dispersion of BF at lower weight fraction, although fibre agglomeration was noticed at higher weight fraction. The results of this study revealed that treated bamboo fibres are suitable for reinforcing HDPE. It appears from these studies that the formulations produced are in accordance with the ASTM standard and can validly be used for the thermal comfort of buildings to improve the comfort of the population in sustainable habitats.","PeriodicalId":14902,"journal":{"name":"Journal of Advanced Chemical Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140491357","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}

Understanding the disease progression and patterns of recurrence is crucial for optimizing treatment strategies and improving patient outcomes. This observational study aimed to investigate the disease progression and patterns of recurrence in oral cancer patients treated with various modalities. \u0000Methods: A retrospective analysis was conducted using data from medical records of oral cancer patients treated at multiple health care institutions between March 2022 to February 2023 across Bhopal city. Demographic characteristics, tumor characteristics, treatment modalities, and long-term follow-up data were collected. The rates and patterns of recurrence, including local, regional, and distant recurrences were analyzed..SPSS 25.0 was used to analyse the data \u0000Results: The study included 237 patients with oral cancer. The majority of patients were males (64.9%) and presented with squamous cell carcinoma (81.8%). The most common site of oral cancer was tongue. Surgical resection was the primary treatment modality, with adjuvant therapies, such as radiation therapy and chemotherapy, utilized in majority of cases. The overall recurrence rate was 62.4%.  Local recurrence occurred in 27.3% of patients, regional recurrence in 59.1% and distant metastasis in 13.6%. \u0000Conclusion: The findings highlight the importance of comprehensive surgical resection, the need for effective adjuvant therapies, and the challenges in achieving long-term disease control. The identified recurrence patterns and prognostic factors can guide treatment decision-making and risk stratification.

This review provides an overview of the current research on biomarkers in OSMF and their potential implications in clinical practice. \u0000The review focuses on the different categories of biomarkers that have shown promise in assessing disease progression and treatment outcomes in OSMF. Epithelial dysplasia markers, including Ki-67, p53, and cyclin D1, are discussed in relation to dysplastic changes observed in OSMF. Inflammatory and immune markers, such as cytokines, chemokines, and inflammatory mediators, are explored for their role in OSMF progression. The dysregulation of extracellular matrix remodelling is highlighted, with a discussion on matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) as potential biomarkers. \u0000Furthermore, the review delves into biomarkers for treatment response and outcome prediction. Collagen turnover markers, including pro-collagen type I and MMPs, are examined as indicators of collagen synthesis and degradation. Oxidative stress markers, such as malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GPx), are evaluated for their ability to reflect oxidative stress and antioxidant status. The review also touches upon the potential of epigenetic markers, such as DNA methylation and histone modifications, in predicting treatment response and prognosis in OSMF. \u0000Additionally, the review explores the use of imaging techniques, including optical coherence tomography (OCT), autofluorescence imaging, and confocal microscopy, for assessing structural changes and biomarker expression in OSMF. It discusses the potential of molecular imaging modalities, such as positron emission tomography (PET) and molecular MRI, for visualizing specific biomarkers in OSMF. Moreover, the review highlights the importance of genomics approaches, including genomics, transcriptomics, proteomics, and metabolomics, in identifying novel biomarkers and unraveling molecular pathways in OSMF. \u0000We emphasize the potential of biomarkers in improving patient care and management in OSMF. It acknowledges the challenges in biomarker validation, standardization, and cost-effectiveness for widespread clinical use. The review calls for further research in emerging areas, such as non-coding RNAs, microRNA panels, and multi-modal biomarker approaches, to enhance our understanding of OSMF and facilitate personalized treatment strategies. \u0000  \u0000 ","PeriodicalId":14902,"journal":{"name":"Journal of Advanced Chemical Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75015885","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}

Light fix cement (Trans bond XT, 3M Unitek, Monrovia, CA) was used to strengthen the metal portions in Group I (n = 30), whereas light glass ionomer concrete (GC Fuji Ortho LC, Tokyo, Japan) was used to accomplish the same in Group II (n = 30). The dried residues of the concrete glue were removed using a TC brush and a slow-speed handpiece. Maximum roughness (Rmax), root mean square roughness (Rq), and roughness (Ra) were all determined at time zero (before holding). and their attributes were compared to those at time two (after debonding and completion). \u0000Results:-The two groups had very different experiences with the roughness of the polished surface when held.
