Direct visualization of interstitial flow distribution in aortic walls

open access: yesScientific Reports, 2022
Vascular smooth muscle cells are exposed to interstitial flow across aortic walls. Fluid shear stress changes the phenotype of smooth muscle cells to the synthetic type; hence, the fast interstitial flow might be related to aortic diseases. In this study,

Limitations of methods for measuring the concentration of human genomic DNA and oligonucleotide samples

open access: yesBioTechniques, 2018
We compared different methods (absorbance, fluorescent dye-binding, and digital PCR) for measuring the concentrations of human genomic DNA from cultured cells and absorbance measurements of a synthetic DNA oligonucleotide.

Antiseptic quaternary ammonium compound tolerance by gram-negative bacteria can be rapidly detected using an impermeant fluorescent dye-based assay

open access: yesScientific Reports, 2020
Biocides such as quaternary ammonium compounds (QACs) are potentially important contributors towards bacterial antimicrobial resistance development, however, their contributions are unclear due to a lack of internationally recognized biocide testing ...

A Novel Fluorescent Dye Invades Mitochondria to Selectively Kill Cancer Stem Cells via Increased ROS Production

open access: yesBioinorganic Chemistry and Applications, 2021
Development of multiple agents has a significant impact on the cancer diagnosis and therapy. Several fluorescent dyes including near-infrared (NIR) fluorescent agents have been already well studied in the field of photodynamic therapy (PDT).

Effect of substrate thermal resistance on space-domain microchannel [PDF]

open access: yes, 2009
In recent years, Fluorescent Melting Curve Analysis (FMCA) has become an almost ubiquitous feature of commercial quantitative PCR (qPCR) thermal cyclers. Here a micro-fluidic device is presented capable of performing FMCA within a microchannel.

Fluorescence changes at flow cytometric analysis of samples from sentinel lymph nodes excised with indocyanine green and methylene blue guided mapping techniques

open access: yesFrontiers in Veterinary Science
IntroductionFlow cytometry (FC) has been used recently to assess percentages of infiltration by mast cells in sentinel lymph nodes (SLN) of dogs with mast cell tumors (MCT). SLN mapping often includes the use of different dyes such as methylene blue (MB)

Recent Progress in Research on [2.2]Paracyclophane-Based Dyes

open access: yesMolecules, 2023
In recent years, the [2.2]paracyclophane (PCP) ring has attracted extensive attention due to its features of providing not only chirality and electron-donating ability but also steric hindrance, which reduces intermolecular π–π stacking interactions and ...
