Journal ArticleDOI
Enhancement of tensile strength of lignocellulosic jute fibers by alkali-steam treatment.
Prosenjit Saha,Suvendu Manna,Sougata Roy Chowdhury,Ramkrishna Sen,Debasis Roy,Basudam Adhikari +5 more
TL;DR: The results from this investigation indicate that a 30 min dipping of the fibers in 0.5% alkali solution followed by 30 min alkali-steam treatment leads to an increase in the tensile strength of up to 65%, which appears to be due to fiber separation and removal of non-cellulosic materials, which, in turn, resulted in an increased crystallinity.
Journal ArticleDOI
Electrospun chitosan/polycaprolactone-hyaluronic acid bilayered scaffold for potential wound healing applications
Amit Chanda,Jaideep Adhikari,Aritri Ghosh,Sougata Roy Chowdhury,Sabu Thomas,Pallab Datta,Prosenjit Saha +6 more
TL;DR: Enhanced swelling, degradation, hydrophilicity and water vapour transmission rate were found for the bilayered scaffold compared to that of the PCL and CS-PCL scaffolds.
Journal ArticleDOI
Exosomes Produced by Mesenchymal Stem Cells Drive Differentiation of Myeloid Cells into Immunosuppressive M2-Polarized Macrophages in Breast Cancer.
Subir Biswas,Gunjan Mandal,Sougata Roy Chowdhury,Suman Purohit,Kyle K. Payne,Carmen M. Anadon,Arnab Gupta,Patricia Swanson,Xiaoqing Yu,Jose R. Conejo-Garcia,Arindam Bhattacharyya +10 more
TL;DR: It is demonstrated that exosomes secreted by human and mouse tumor-educated mesenchymal stem cells drive accelerated breast cancer progression by inducing differentiation of monocytic myeloid-derived suppressor cells into highly immunosuppressive M2-polarized macrophages at tumor beds.
Journal ArticleDOI
CXCL13–CXCR5 co-expression regulates epithelial to mesenchymal transition of breast cancer cells during lymph node metastasis
Subir Biswas,Suman Sengupta,Sougata Roy Chowdhury,Samir Jana,Gunjan Mandal,Palash Kumar Mandal,Nipun Saha,Vivek Malhotra,Arnab Gupta,Dmitry V. Kuprash,Arindam Bhattacharyya +10 more
TL;DR: The EMT-inducing potential of CXCL13 is shown as well as the prognostic value of C XCL13–CXCR5 co-expression in primary BC is demonstrated, suggesting that CxCL13-CX CR5–RANKL–Src axis may present a therapeutic target in LNM positive BC patients.
Journal ArticleDOI
Bacterial fucose-rich polysaccharide stabilizes MAPK-mediated Nrf2/Keap1 signaling by directly scavenging reactive oxygen species during hydrogen peroxide-induced apoptosis of human lung fibroblast cells.
Sougata Roy Chowdhury,Sougata Roy Chowdhury,Suman Sengupta,Subir Biswas,Tridib Kumar Sinha,Ramkrishna Sen,Ratan Kumar Basak,Basudam Adhikari,Arindam Bhattacharyya +8 more
TL;DR: This molecular study uniquely introduces a fucose-rich bacterial polysaccharide as a potential inhibitor of H2O2-induced stress and toxicities.
