Evaluation of DNA/Chromosome Integrity and Cell Death in Human Metabolically Noncompetent and Competent Cells Exposed to N′‐(3,5‐Difluorobenzylidene)Pyridine‐4‐Carbohydrazide

Journal of Applied Toxicology, EarlyView.
ABSTRACT The N‐acylhydrazone scaffold is recognized as a privileged structure for the design of bioactive substances with increasing applications in medicinal chemistry research. Ensuring the safety of newly developed molecules is a critical step for both human health and environmental protection. Accordingly, this study aimed to evaluate the cytotoxic

Quantifying Benthic Biolayer Contributions to Whole‐Stream Reactivity by Unifying Surface and Subsurface Observations: Field Evidence and Theory

Water Resources Research
The benthic biolayer is a shallow zone of reactive streambed sediments, widely believed to contribute disproportionately to whole‐stream reactions such as aerobic respiration and contaminant transformation.

Cationic‐Hydrophilic Di‐Block Copolymers: Surface‐Shielded Vectors for Gene Delivery

Journal of Polymer Science, Volume 63, Issue 6, Page 1419-1432, 15 March 2025.
This study develops synthetic polycationic di‐block carriers for nucleic acid (NA) delivery in gene therapy. Consisting of a cationic block and a hydrophilic block, these carriers efficiently form complexes with NAs and shield them with a protective bioinert layer, enhancing stability during circulation in the bloodstream while reducing undesirable ...

The Use of Baker’s Yeast in the Resazurin Reduction Test: A Simple, Low-Cost Method for Determining Cell Viability in Proliferation and Cytotoxicity Assays

Journal of Microbiology & Biology Education, 2018
Cell viability assays require expensive commercial testing kits and sophisticated cell culture techniques. Thus, a laboratory activity for testing the cellular proliferative and cytotoxic effects of certain substances using baker’s yeast (Saccharomyces ...

Construction of an O2‐responsive engineering bioreactor for enhanced indole‐3‐propionic acid production and deoxynivalenol detoxification

Responsive Materials, EarlyView.
An oxygen‐responsive living bioreactor was engineered via interspecies protoplast fusion, converting oxygen from an inhibitory stress into a programmable signal for sustained indole‐3‐propionic acid (IPA) production. This genetically encoded bioreactor enables robust aerobic operation and therapeutic efficacy of deoxynivalenol detoxification in vivo ...

Evaluation of crystal violet decolorization assay and resazurin microplate assay for antimycobacterial screening

Heliyon, 2019
The main obstacle in antimycobacterial discovery is the extremely slow growth rates of pathogenic mycobacteria that lead to the long incubation times needed in antimycobacterial screening.

SERS‐Based Nano‐ and Microsystems Toward Biomedical Applications

Small, EarlyView.
This review provides a current overview of nano‐ and microscale SERS‐based devices, encompassing all aspects from material design to practical applications. We highlight controlled SERS‐active architectures, including patterned substrates, nanorods, microspheres, micromotors, and microneedles, as well as combinations of these microfluidic systems.

Measuring Propidium Iodide Brightness as a Function of Viability: A High‐Throughput Quantitative Assessment of Hepatic Spheroids

Artificial Organs, EarlyView.
The graphical abstract illustrates our rapid PI‐based spheroid viability assay: hepatocyte spheroids are formed and stained with AO/PI, imaged after a 15‐min incubation, and analyzed for PI brightness normalized to area. This metric correlates strongly with functional urea/DNA output, validating PI intensity as a fast, reliable indicator of spheroid ...

Dual pharmacological targeting of coactivator‐associated arginine methyltransferase 1 (CARM1) and salt inducible kinase (SIK) drives ketogenesis in both hepatocytes and mice

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ketone bodies are liver‐derived circulating energy metabolites that positively impact most hallmarks of ageing. Ketone bodies increase during calorie restriction and fasting, two of the more widely perceived methods to increase health span.
