Cationic Polymers Inhibit the Conductance of Lysenin Channels

The Scientific World Journal, 2013
The pore-forming toxin lysenin self-assembles large and stable conductance channels in natural and artificial lipid membranes. The lysenin channels exhibit unique regulation capabilities, which open unexplored possibilities to control the transport of ...

Duramycin-induced calcium release in cancer cells [PDF]

, 2015
Introduction: Duramycin through binding with phosphatidylethanolamine (PE) has shown potential to be an effective anti-tumour agent. However its mode of action in relation to tumour cells is not fully understood.

Photoswitching Conduction in Framework Materials

Advanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

Excitable artificial membrane mimicking nervous membrane.

membrane, 1986
Sustained rhythmic oscillations of electrochemical potential occur spontaneously across a fine-pore membrane doped with glycerol-α-monooleate (monoolein), sorbitan monooleate (Span 80) or glycerol trioleate (triolein), separating equimolar solutions of KCl and NaCl : these oscillations occur in the absence of any external stimulus such as voltage, an ...

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells

Advanced Functional Materials, EarlyView.
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

Endodontic surgery with bone graft: apicoectomy of left maxilar lateral incisor

RGO: Revista Gaúcha de Odontologia
In cases where endodontic treatment is unsuccessful, endodontic retreatment is usually the first option for clinical management. However, it is possible for periapical infection to persist. Eventually, these apical infections reach inaccessible locations,

A water-soluble form of porin from the mitochondrial outer membrane of Neurospora crassa [PDF]

, 1985
Mitochondrial porin, the outer membrane pore-forming protein, was isolated in the presence of detergents and converted into a water- soluble form. This water-soluble porin existed under nondenaturing conditions as a mixture of dimers and oligomers.

Specific Adhesion of Membranes Simultaneously Supports Dual Heterogeneities in Lipids and Proteins [PDF]

, 2015
Membrane adhesion is a vital component of many biological processes. Heterogeneities in lipid and protein composition are often associated with the adhesion site. These heterogeneities are thought to play functional roles in facilitating signalling. Here

Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

Advanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...
