Transmission Raman Spectroscopy (TRS) for Accurate Authentication of API in Coated Hydroxychloroquine (HCQ) Tablets

open access: yesJournal of Raman Spectroscopy, EarlyView.
We report the development and use of a transmission Raman spectroscopy (TRS) system for a more accurate but nonintrusive way of authentication of API in coated HCQ tablets which otherwise is not possible using the backscattered (BS) configuration of Raman spectroscopy. The coating interference is found to be almost zero in case of the TRS and a greater

Bioconversion and characterization of watermelon rind waste‐based microcrystalline cellulose: A green alternative to synthetic reinforcements

open access: yesPolymer International, EarlyView.
Microcrystalline cellulose (MCC) was extracted from watermelon rind using acid hydrolysis. MCC can be efficiently used as reinforcement in biofilms and biocomposites. Abstract The increasing accumulation of agricultural waste from watermelon (Citrullus lanatus) represents a substantial environmental concern, particularly in view of the extensive ...

Bioinformatics‐Driven Design and Evaluation of Recombinant Multi‐Epitope Immunogens Derived From Snake Venom Toxins as Potential Antivenom Candidates

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Snakebite envenomation is a major public health concern, particularly in low‐ and middle‐income regions where access to safe and effective antivenoms is limited. Traditional antivenoms, derived from immunization with crude venom, often trigger adverse reactions and lack specificity against key venom components.

In Vitro Reconstruction of Axonal Heat Sensing with a Photothermal Nerve‐on‐a‐Chip

open access: yesSmall, EarlyView.
A photothermal nerve‐on‐a‐chip platform is presented that enables precise, localized heating of sensory axons with simultaneous electrical recording. The system reveals millisecond‐scale dynamics of heat‐evoked neural activity and provides a new approach to study how temperature‐dependent ion channel behavior is translated into axonal firing.

A novel sulfur‐containing photoinitiator based on benzophenone derivatives for rapid photopolymerization

open access: yesSmart Molecules, EarlyView.
This study develops a series of unimolecular photoinitiators, BP‐S1‐5, by incorporating hydrogen‐donating groups into a benzophenone framework. This method reduces the reliance on co‐initiators, and enables BP‐S1‐5 with efficient photoinitiation and excellent molding capability.

Nanobody–chlorin e6 conjugate for Nectin‐4‐mediated tumor targeting and enhanced photodynamic therapy

open access: yesVIEW, EarlyView.
Nectin‐4 is frequently overexpressed in solid tumors, yet many PDT photosensitizers show poor water solubility and nonspecific uptake. A Nectin‐4‐targeted nanobody–chlorin e6 conjugate (NPC) improves aqueous solubility and selectively accumulates in Nectin‐4‐positive tumor cells.

Targeting Inflammatory Alarmin S100A9 Modulates Activation of Pro‐Inflammatory Macrophage to Protect Nasal Epithelial Cells From LPS‐Induced Epithelial–Mesenchymal Transition

open access: yesMicrobiology and Immunology, EarlyView.
ABSTRACT Chronic rhinosinusitis with nasal polyps (CRSwNP) exhibits pronounced endotypic heterogeneity, with macrophages serving as key drivers of sustained mucosal inflammation. In this study, we identify S100A9 as a macrophage‐derived alarmin that is markedly elevated in CRSwNP tissues.
