The aim of this study was to investigate the effect of fish size and seasonality on the epidermis structure and protein profile of the skin mucus of Rainbow trout. Skin mucus samples were collected over three consecutive season periods including late winter, mid spring and early autumn. In each season, sampling was performed separately from three different weight groups including 2-20 gr fish (...
BACKGROUND Mucus stasis in chronic obstructive pulmonary disease (COPD) is a significant contributor to morbidity and mortality. Potentiators of cystic fibrosis transmembrane conductance regulator (CFTR) activity pharmacologically enhance CFTR function; ivacaftor is one such agent approved to treat CF patients with the G551D-CFTR gating mutation. CFTR potentiators may also be useful for other d...
Nanoscale analysis may be used to design new types of mucoadhesive polymers. Understanding of the surface interactions between hydrophilic polymer surfaces and mucins can lead to improved adhesive bonding by hydrogen bonding. Alternatively, decoration of a mucoadhesive polymer surface with tethers of linear and block copolymers containing neutral or ionizable structures provides increased inter...
Pseudomonas aeruginosa commonly infects the airways of patients with cystic fibrosis and bronchiectasis. It produces several toxins that slow ciliary beat, stimulate mucus production and damage epithelium. It adheres to epithelial cells, damaged mucosa (in animal models), and mucus. However, little is known of the interaction of P. aeruginosa with intact human respiratory mucosa. We have studie...
Magnetic Soft Robots In article number 2201813, Venkatsubramanian Kalpathy Venkiteswaran and co-workers develop a biocompatible soft polymer film for coating the outer surface of robot which can be controlled using magnetic fields. The Chitosan-Glycerol endows with ability locomotion on confined 3D surfaces through formation hydrogen bonds mucus-covered biological surfaces.

The mucus overlying mucosal epithelial surfaces presents not only a biological barrier to the penetration of potential pathogens, but also therapeutic modalities including RNAi-based nanocarriers. Movement of nanomedicines across the mucus barriers of the gastrointestinal mucosa is modulated by interactions of the nanomedicine carriers with mucin glycoproteins inside the mucus, potentiated by t...
Mucus hypersecretion associated with airway inflammation is reduced by glucocorticoids. Two mechanisms of glucocorticoid-mediated inhibition of mucus production have been proposed, direct inhibition of mucus production by airway epithelial cells and indirectly through inhibition of proinflammatory mediators that stimulate mucus production. In this study, we examined the effect of dexamethasone ...
