Fusion of isolated myoblast plasma membranes [PDF]

, 1978
Fusion of plasma membranes isolated from myoblasts grown in culture has been investigated. 1. 1. Membrane fusion was specifically dependent on Ca2+ at physiological concentrations. However, at higher concentrations of cations, fusion could be triggered

On‐Surface Indigo‐Based Bimolecular Coordination Networks with Programmable Regular or Vitreous Structure

Advanced Functional Materials, EarlyView.
A previously unreported coordination motif stabilising single Fe atoms by indigo chelation and pyridyl coordination on Au(111) has been revealed. By using planar tritopic pyridyl linkers (TPyB), extended 2D porous networks of indigo3(TPyB)2Fe6 form. These networks can be crystalline or vitreous and offer an environment where individual coordination ...

Chromoionophores in optical ion sensors [PDF]

, 1989
The feasibility of surface plasmon resonance (SPR) for ion sensing has been investigated. Emphasis is laid on a simulation-based optimization of the SP carrying structure, as well as the applicability of a specific chemo—optical interface we have ...

Ionophore antibiotics and hop cones as regulators of digestion and metabolism in ruminants

Біологічні студії
The general characteristics of ionophore antibiotics and the mechanisms of their antimicrobial action were analyzed. Two types of ionophore antibiotics are known: those that transport ions across the membrane, and those that form a channel in the cell ...

An ionophore breaks the multi-drug-resistance of Acinetobacter baumannii

Microbial Cell, 2022
Within intensive care units, multi-drug resistant Aci-netobacter baumannii outbreaks are a frequent cause of ventilator-associated pneumonia. During the on-going COVID-19 pandemic, patients who receive venti-lator support experience a 2-fold increased ...

Small Extracellular Vesicles from Neural Cells: Physiological and Pathological Roles, and Potential in Neurodegenerative Therapy

Advanced Healthcare Materials, EarlyView.
Neural cell–derived small extracellular vesicles (sEVs) are emerging as pivotal mediators in neurodegenerative diseases, exerting both pathogenic and therapeutic functions. This review synthesizes current evidence on how sEVs from distinct neural cell types regulate neurodegeneration, neuroprotection, biomarker discovery, and targeted drug delivery ...
