Item Doxorubicin-Intercalated Li-Al-Based LDHs as Potential Drug Delivery Nanovehicle with pH-Responsive Therapeutic Cargo for Tumor Treatment(American Chemical Society, 2024) Maity S.; Dubey D.K.; Meena J.; Shekher A.; Singh R.S.; Maiti P.Clinical oncology is currently experiencing a technology bottleneck due to the expeditious evolution of therapy defiance in tumors. Although drugs used in chemotherapy work for a sort of cell death with potential clinical application, the effectiveness of chemotherapy-inducing drugs is subject to several endogenous conditions when used alone, necessitating the urgent need for controlled mechanisms. A tumor-targeted drug delivery therapy using Li-Al (M+/M3+)-based layered double hydroxide (LDHs) family has been proposed with the general chemical formula [M+1-x M3+x (OH)]2x+[(Am-)2x/m. n(H2O)]2x?, which is fully biodegradable and works in connection with the therapeutic interaction between LDH nanocarriers and anticancerous doxorubicin (DOX). Compositional variation of Li and Al in LDHs has been used as a nanoplatform, which provides a functional balance between circulation lifetime, drug loading capacity, encapsulation efficiency, and tumor-specific uptake to act as self-regulatory therapeutic cargo to be released intracellularly. First-principle analyses based on DFT have been employed to investigate the interaction of bonding and electronic structure of LDH with DOX and assess its capability and potential for a superior drug carrier. Following the internalization into cancer cells, nanoformulations are carried to the nucleus via lysosomes, and the mechanistic pathways have been revealed. Additionally, in vitro along with in vivo therapeutic assessments on melanoma-bearing mice show a dimensional effect of nanoformulation for better biocompatibility and excellent synergetic anticancer activity. Further, the severe toxic consequences associated with traditional chemotherapy have been eradicated by using injectable hydrogel placed just beneath the tumor site, and regulated release of the drug has been confirmed through protein expression applying various markers. However, Li-Al-based LDH nanocarriers open up new design options for multifunctional nanomedicine, which has intriguing potential for use in cancer treatment through sustained drug delivery. � 2024 American Chemical Society.Item Jaws of knowledge: an analysis of temporomandibular joint insights in dental training�a quasi-experiment study(Korean Association of Oral and Maxillofacial Surgeons, 2024) Bhagat B.R.; Khairnar M.R.; Maity S.; Sachdev M.M.; Shah S.; Dharamsi R.Objectives: To access the knowledge of undergraduate and postgraduate students of the dental college on basic anatomy, physiology, clinical examination, and pathology of the temporomandibular joint (TMJ). Materials and Methods: A total of 610 undergraduate and postgraduate students of dental college, were included in this study. The questionnaire was pretested for validation and distributed online through Google forms. Results: A pairwise comparison showed that the percentage of correct answers for interns significantly differed from that of IV Bachelor of Dental Surgery (P=0.050) and postgraduate students (P=0.048) (below average: up to 6 correct answers, good: 7-11 correct answers, excellent: 12 or more correct answers). Conclusion: TMJ diseases are common in daily life but frequently go undiagnosed and untreated due to a lack of clinical expertise. This demonstrates the necessity of providing instructions that give students in-depth knowledge and abilities for TMJ issues in clinical practice. � 2024 The Korean Association of Oral and Maxillofacial Surgeons.Item Neurogenic and angiogenic poly(N-acryloylglycine)-co-(acrylamide)-co-(N-acryloyl-glutamate) hydrogel: preconditioning effect under oxidative stress and use in neuroregeneration(Royal Society of Chemistry, 2024) Wasnik K.; Gupta P.S.; Singh G.; Maity S.; Patra S.; Pareek D.; Kumar S.; Rai V.; Prakash R.; Acharya A.; Maiti P.; Mukherjee S.; Mastai Y.; Paik P.Traumatic injuries, neurodegenerative diseases and oxidative stress serve as the early biomarkers for neuronal damage and impede angiogenesis and subsequently neuronal growth. Considering this, the present work aimed to develop a poly(N-acryloylglycine)-co-(acrylamide)-co-(N-acryloylglutamate) hydrogel [p(NAG-Ac-NAE)] with angiogenesis/neurogenesis properties. As constituents of this polymer modulate their vital role in biological functions, inhibitory neurotransmitter glycine regulates neuronal homeostasis, and glutamatergic signalling regulates angiogenesis. The p(NAG-Ac-NAE) hydrogel is a highly branched, biodegradable and pH-responsive polymer with a very high swelling behavior of 6188%. The mechanical stability (G?, 2.3-2.7 kPa) of this polymeric hydrogel is commendable in the differentiation of mature neurons. This hydrogel is biocompatible (as tested in HUVEC cells) and helps to proliferate PC12 cells (152.7 � 13.7%), whereas it is cytotoxic towards aggressive cancers such as glioblastoma (LN229 cells) and triple negative breast cancer (TNBC; MDA-MB-231 cells) and helps to maintain the healthy cytoskeleton framework structure of primary cortical neurons by facilitating the elongation of the axonal pathway. Furthermore, FACS results revealed that the synthesized hydrogel potentiates neurogenesis by inducing the cell cycle (G0/G1) and arresting the sub-G1 phase by limiting apoptosis. Additionally, RT-PCR results revealed that this hydrogel induced an increased level of HIF-1? expression, providing preconditioning effects towards neuronal cells under oxidative stress by scavenging ROS and initiating neurogenic and angiogenic signalling. This hydrogel further exhibits more pro-angiogenic activities by increasing the expression of VEGF isoforms compared to previously reported hydrogels. In conclusion, the newly synthesized p(NAG-Ac-NAE) hydrogel can be one of the potential neuroregenerative materials for vasculogenesis-assisted neurogenic applications and paramount for the management of neurodegenerative diseases. � 2024 The Royal Society of Chemistry.Item Pyrene-tagged poly(N-vinyl pyrrolidone) as efficient nano-carrier for anticancer drug delivery(Taylor and Francis Ltd., 2024) Mitra K.; Maity S.; Hajra A.; Singh S.; Mondal S.; Singh J.; Maiti P.; Ray B.Herein, we report the use of self-assembled amphiphilic pyrene-tagged poly(N-vinyl pyrrolidone) (PyPNVP) micelles as effective anticancer delivery vehicle. Self-assembly phenomenon of PyPNVP has been studied in aqueous medium. Anticancer drug doxorubicin has been encapsulated in the hydrophobic micellar core and in�vitro release profiles have been explored in four different pH values (pH 7.4 ? 1.4). The drug-loaded construct has shown pH-responsive higher drug release at lower pH. Anticancer activity of the construct has been studied against human squamous cell carcinoma of the cervix uteri cell line. The in�vitro study has shown the highly effective tumoricidal activity. � 2023 Taylor & Francis Group, LLC.Item Solid-state synthesis of novel anticancer drug eutectic mixture; anticancer, physical and thermal studies(Elsevier B.V., 2024) Chaudhary S.; Rai R.N.; Maity S.; Maiti P.Green, solvent-free synthesis is adopted for a new pharmaceutical drug-drug eutectic with the utmost 100% yield. The synthesized eutectic mixture is significant for anticancer activity. The mandate of clinical tests could be avoided as selected nicotinamide, salicylamide, p-aminoacetinilide and benzanilide are known drugs. The compositional behaviors and established phase diagrams infer the formation of eutectics. The thermal behaviors of eutectics are studied using DSC. Further studies of eutectics are targeted for their biological applications, particularly for cell viability and anticancer activity against SiHa cancer cells where eutectic of benzanilide-salicylamide system infers its potential applicability for anticancer activity. � 2024Item Synthesis of an Aryl-Semicarbazone-Based Cu(II) Complex for DNA and BSA Interaction and Anti-Cancer Activity against Human Cervix Uteri Carcinoma(Multidisciplinary Digital Publishing Institute (MDPI), 2024) Maity R.; Manna B.; Maity S.; Jana K.; Maity T.; Afzal M.; Sepay N.; Samanta B.C.The current study provides an in-depth analysis of the biological properties of a Cu(II) complex (C22H24Cu2N6O10) obtained from an aryl-semicarbazone ligand derived (L) from the condensation of 2,4-dihydroxy acetophenone and semicarbazide. The binding behavior of this complex with calf thymus DNA (CT-DNA) and bovine serum albumin (BSA) protein was explored using a combination of experimental and theoretical approaches. The results suggest that the complex binds with CT-DNA via a partial intercalation, and hydrophobic interaction. However, the complex binds to BSA protein predominantly through hydrogen bonding or van der Waals interactions rather than hydrophobic interactions. The molecular docking methodology was carried out to substantiate the experimental finding. Furthermore, the in vitro cytotoxicity study was conducted on human cervix uteri carcinoma (SiHa cancerous cell) lines upon exposure to the complex, and the findings reveal a considerable decrease in cell viability, when compared to the control. Overall, this study provides a comprehensive understanding of the biological potential of the Cu(II) complex and its potential as an anti-cancer agent. � 2024 by the authors.
