Background And Aim: Endocytoscopy (EC) at ultra-high magnification enables in vivo visualization of cellular atypia of gastrointestinal mucosae. Clear images are essential for precise diagnosis by EC. The aim of the present study was to evaluate the optimal staining method for EC in the colon.
Methods: Thirty prospectively enrolled patients were allocated 1:1:1 to three distinct staining methods: 0.05% crystal violet (CV) alone, 1% methylene blue (MB) alone, or CV+MB (CM double). Normal rectal mucosae were stained with each dye and videos of EC images were recorded. Visibility of nuclei and gland formation after staining were evaluated as 'recognizable' or 'not recognizable'. Time for each parameter to become 'recognizable' was measured, and the average times for the three staining regimens were compared.
Results: MB alone and CM double staining resulted in 'recognizable' (102 ± 27 vs 89 ± 22 s, P=0.263) nuclei within comparable periods of time, whereas CV alone was unable to identify nuclei. Gland formation became 'recognizable' sooner after CM double staining than after MB alone (61 ± 16 vs 108 ± 24 s, P<0.001).
Conclusions: Double staining with CV and MB, which rapidly provided recognizable images of both nuclei and gland formation, is an appropriate staining regimen for colonic EC.

Glutathione (GSH) plays a crucial role in various physiological processes and its imbalances are closely related to various pathological conditions. Probes for detection and imaging of GSH are not only useful for understanding GSH chemical biology but are also important for exploring potential theranostic agents. Herein, we report a fast intramolecular thiol-activated arylselenoamides ()-based fluorescent probe using 2,4-dinitrophenyl alkylthioether as a sulfydryl-selective receptor for the first time.

The combination of alcohol and a low-carbohydrate, high-protein, high-fat atherogenic diet (AD) increases the risk of lethal arrhythmias in apolipoprotein E/low-density lipoprotein receptor double-knockout (AL) mice with metabolic dysfunction-associated steatotic liver disease (MASLD). This study investigates whether left ventricular (LV) myocardial interstitial fibrosis (MIF), formed during the progression of metabolic dysfunction-associated steatohepatitis (MASH), contributes to this increased risk. Male AL mice were fed an AD with or without ethanol for 16 weeks, while age-matched AL and wild-type mice served as controls.

Methimazole (MMI) is an emerging endocrine disrupting chemical (EDC) due to its increasing use in the treatment of thyrotoxicosis (hyperthyroidism), but its potential impact on amphibian development remains largely unexplored. In the present study, the effects of 8 mg/L MMI and 1 μg/L thyroxine (T4) exposure on skeletal ossification and muscle development in Bufo gargarizans tadpoles were comprehensively investigated by double skeletal staining, histological analysis and RNA sequencing. Our results indicated that MMI treatment down-regulated the expression levels of ossification-related genes (e.

Innovative double-emission carbon dots (DE-CDs) were synthesized via a one-step hydrothermal method using fennel and m-phenylenediamine (m-PD) as precursors. These DE-CDs exhibited dual emission wavelengths at 432 and 515 nm under different excitations, making them highly versatile for fluorescence-based applications. The fluorescence of the DE-CDs was efficiently quenched by tetracycline (TC) through the inner filter effect (IFE), allowing for the construction of a sensitive dual-response fluorescent sensor.
