Neutral polyphosphocholine-modified liposomes as boundary superlubricants [PDF]

arXiv, 2022
Boundary lubrication is associated with two sliding molecularly thin lubricated film-coated surfaces, where the energy dissipation occurs at the slip-plane between lubricated films. The hydration lubrication paradigm, which accounts for ultralow friction in aqueous media, has been extended to various systems, with phosphatidylcholine (PC) lipids ...

High‐Resolution Patterned Delivery of Chemical Signals From 3D‐Printed Picoliter Droplet Networks

Advanced Materials, EarlyView.
3D‐printed picoliter droplet networks have been fabricated that control gene expression in bacterial populations by releasing chemical signals with precise spatial definition and high temporal resolution. This system of effector release is widely applicable, offering diverse applications in biology and medicine.

HOCl-modified phosphatidylcholines induce apoptosis and redox imbalance in HUVEC-ST cells [PDF]

, 2014
Electrophilic attack of hypochlorous acid on unsaturated bonds of fatty acyl chains is known to result mostly in chlorinated products that show cytotoxicity to some cell lines and were found in biological systems exposed to HOCl.

An Anticoagulant Coating Based on a Block Phosphocholine Copolymer for Potential Applications in Blood Contact Devices

Advanced Materials Interfaces, EarlyView.
Anticoagulant properties are critical for blood‐compatible materials, and anticoagulant coatings are a common key issue for blood‐contacting medical devices. In this study, a block copolymer poly(2‐methacrylenoxyethyl phosphocholine‐b‐glycidyl) (PMPC‐b‐GMA) is synthesized, using reversible addition‐fragmentation chain transfer polymerization (RAFT) and

Juvenile Male Rats Exposed to a Low-Dose Mixture of Twenty-Seven Environmental Chemicals Display Adverse Health Effects [PDF]

, 2016
Humans are exposed to a large number of environmental chemicals in their daily life, many of which are readily detectable in blood or urine. It remains uncertain if these chemicals can cause adverse health effects when present together at low doses.

Preferential Membrane Remodeling on Curved Biointerfaces Induced by Conjugated Oligoelectrolyte

Advanced Materials Interfaces, EarlyView.
This study explores how membrane shape influences the interaction of conjugated oligoelectrolytes (COEs) with lipid bilayers. Using a curved biointerface composed of nanobar arrays and supported lipid bilayers, it is revealed that COE intercalation preferentially remodels curved regions, forming distinct structures. These findings highlight the role of

Influence of Ibuprofen on Phospholipid Membranes [PDF]

Phys. Rev. E 91, 022716 (2015), 2014
Basic understanding of biological membranes is of paramount importance as these membranes comprise the very building blocks of life itself. Cells depend in their function on a range of properties of the membrane, which are important for the stability and function of the cell, information and nutrient transport, waste disposal and finally the admission ...

Lecithin Alleviates Memory Deficits and Muscle Attenuation in Chinese Older Adults and SAMP8 Mice

Advanced Science, EarlyView.
This study opens a new avenue for safeguarding cognition and muscle health, averting disability in older age, and treating age‐related pathologies through lecithin supplementation. It serves as a promising nonpharmacological intervention for the crosstalk of muscle and cognition.
