Topotecan in First-Line Small Cell Lung Cancer
2026-09-24
David J. Stewart’s review examines whether topotecan-based combinations could extend first-line options for small cell lung cancer (SCLC), drawing on phase II results rather than a new clinical trial. The combinations showed encouraging response signals, but reversible neutropenia and the need for confirmatory studies limit how firmly they can be compared with established cisplatin–etoposide therapy.

JC-1 Workflows for Mitochondrial Potential Studies
2026-09-24
Use JC-1 to track mitochondrial membrane-potential shifts during cancer-cell treatment studies, with practical guidance for plate-reader, imaging, and flow-cytometry workflows. The assay can complement drug-response measurements—but it should not be mistaken for a direct measure of apoptosis or a mechanism proven by the featured nanocrystal study.

Ferroelectric–Liquid Metal Artificial Photoreceptor
2026-09-22
The reference study reports a ferroelectric P(VDF-TrFE) film containing azo polymer-grafted liquid-metal nanoparticles that produces photoelectric signals across visible and near-infrared wavelengths. Its most important advance is circuit-free biomimetic adaptation, combined with restoration of light sensitivity and extension of infrared perception in retinal-degeneration models.

H2S Deficiency and ER Stress in Diabetic Cardiomyopathy
2026-09-21
The reference study identifies reduced endogenous hydrogen sulfide production as a mechanistic feature of lipotoxic myocardial injury and links this deficiency to endoplasmic reticulum stress. Its patient, rat, and cardiomyocyte models suggest that H2S supplementation and ER-stress inhibition can reduce lipid accumulation, apoptosis, and loss of cell viability, while also defining important limits for translating these findings into imaging workflows.
