Co-opted oxysterol-binding ORP and VAP proteins channel sterols to RNA virus replication sites via membrane contact sites. [PDF]

PLoS Pathogens, 2014
Viruses recruit cellular membranes and subvert cellular proteins involved in lipid biosynthesis to build viral replicase complexes and replication organelles.

Earthing effects on mitochondrial function: ATP production and ROS generation

FEBS Open Bio, EarlyView.
In contrast to sham and naive controls, grounded mitochondria not only exhibit significantly enhanced energy production but also demonstrate a remarkable reduction in membrane potential and oxidative stress. This suggests a profound improvement in mitochondrial health, presenting a promising avenue for therapeutic interventions.

Shape transformations of lipid vesicles by insertion of bulky-head lipids [PDF]

, 2015
Lipid vesicles, in particular Giant Unilamellar Vesicles (GUVs), have been increasingly important as compartments of artificial cells to reconstruct living cell-like systems in a bottom-up fashion.

Semipermeable parylene membrane as an artificial Bruch's membrane

2011 16th International Solid-State Sensors, Actuators and Microsystems Conference, 2011
This paper investigates the feasibility of a mesh-supported submicron-thick semipermeable parylene-C membrane as an artificial Bruch's membrane for the treatment of age-related macular degeneration (AMD). First, the permeabilities of parylene-C membranes with different thickness were measured and the results showed that as-deposited 0.30µm-thick ...

Biophysical characterization and ion transport with cell‐based and proteoliposome reconstitution assays of invertebrate K+‐Cl− cotransporters

FEBS Open Bio, EarlyView.
The K+‐Cl− cotransporters (KCCs) facilitate the symport of ions across the plasma membrane. They participate in physiological processes including neuronal regulation. Here, we characterized KCCs from Drosophila and Hydra vulgaris. Comparative analyses of transporters provide insights into the mechanism of KCC ion transport, regulation, and evolution ...

Extracellular calcium reduction strongly increases the lytic capacity of pneumolysin from streptococcus pneumoniae in brain tissue [PDF]

, 2011
Background. Streptococcus pneumoniae causes serious diseases such as pneumonia and meningitis. Its major pathogenic factor is the cholesterol-dependent cytolysin pneumolysin, which produces lytic pores at high concentrations.

Membranes with artificial free-volume for biofuel production

Nature Communications, 2015
Free-volume of polymers governs transport of penetrants through polymeric films. Control over free-volume is thus important for the development of better membranes for a wide variety of applications such as gas separations, pharmaceutical purifications ...

Preparation and characterization of renal cell peptides from fetal rats for their antitumor activity

FEBS Open Bio, EarlyView.
This study aimed to prepare renal cells (RCs) from fetal rats which were digested by enzymes. Candidate peptides RCPs were characterized by capillary HPLC and MS and their bioactivity was predicted using peptideranker. The predicted top 10 bioactive peptides were synthesized.
