The efficacy of protease and ethylenediaminetetraacetic acid, tetrasodium salt dihydrate (EDTA)-Tween 20 in unmasking bovine respiratory syncytial virus (BRSV) antigens in formalin-fixed lung tissue was compared using avidin-biotin immunoperoxidase procedure. Tissues were taken from experimentally infected lambs. BRSV antigen stained in both techniques. Treatment with EDTA-Tween 20 resulted in more intense staining of BRSV infected cells, more uniform cytoplasmic staining, less non-specific background, and superior cellular detail in comparison to protease digestion.

Abstract Nanosilver particles (NSPs) used by customers may contain detergents/solvents. However, in most of the toxicological studies, nanosilvers are prepared in water and very little is known about the interaction of these agents with NSPs in causing adverse effects. The aim of this study was to investigate the interaction of NSPs and tween-20 in causing tissue injuries after inhalation. In this experiment, 16 rats were divided into four groups (n=4/group) as follows. Controls, exposed to water vapors; Tween-treated exposed to tween-20 alone (0.01% V/V); NSP-tween group exposed to 1000 ppm c

In addition to autofluorescence quenching, it is necessary to take into account the need for histological readability of tissue sections when using counterstains afterwards.

Topical wound management is often a challenge due to the poor penetration of antimicrobials in wound tissue and across the biofilm matrix where bacteria are embedded. Surfactants have been used for decades to improve the stability of formulations, increase drug solubility, and enhance penetration. In this study, we screened different detergents with respect to their cytotoxicity and their ability to improve the penetration of poly-lactic-co-glycolic acid (PLGA) particles in wound tissue. Among the tested surfactants, Kolliphor SLS and Tween 80 increased the penetration of PLGA particles and ha

Detergents represent a unique class of chemical compounds. They can alter surface and interphase bonds, and form micellar systems. These detergent properties allow to alter wettability of surfaces, stabilize or destabilize dispersed systems, and modify the properties of liquid phases. Therefore, the use of detergents is virtually unlimited in chemical synthesis and processing, medicine, biological systems and agricultural biology.

Abstract A new formulation (niosomes) was prepared to enhance the bioavailability, hepatic tissue uptake, and hepatoprotective activity of glutathione (GSH). The GSH-loaded niosomes (nanoform, N-GSH) were formulated by the thin-film hydration technique using cholesterol/non-ionic surfactants (Span®40, Span®60, and Tween®80) at a componential ratio of 1:1 and 2:1. The hepatoprotective activity of N-GSH, GSH, and the standard silymarin against CCl4-induced liver damage and oxidative stress were tested on the rats’ model.
