Understanding and measuring mechanical signals in the tumor stroma
FEBS Open Bio, EarlyView.This review discusses cancer‐associated fibroblast subtypes and their functions, particularly in relation to extracellular matrix production, as well as the development of 3D models to study tumor stroma mechanics in vitro. Several quantitative techniques to measure tissue mechanical properties are also described, to emphasize the diagnostic and ...

FEBS Open Bio, EarlyView.We provide a step‐by‐step guide for producing E140 antigen fragments from Plasmodium berghei (Pb1) and Plasmodium vivax (Pv1). Pb1/Pv1 are expressed in E. coli, solubilized by freeze–thawing, refolded by slow dilution, purified by affinity chromatography (IMAC), then concentrated and subjected to quality control.

A Magnetic Velocity Verlet Method [PDF]
, 2020 We discuss an extension of the velocity Verlet method that accurately approximates the kinetic-energy-conserving charged particle motion that comes from magnetic forcing. For a uniform magnetic field, the method is shown to conserve both particle kinetic energy and magnetic dipole moment better than midpoint Runge-Kutta.

Evaluation of synaptotagmin‐1 action models by all‐atom molecular dynamics simulations
FEBS Open Bio, EarlyView.We used molecular dynamics simulations to test models proposing that synaptotagmin‐1 facilitates membrane fusion by perturbing lipid bilayers, inducing membrane curvature and/or bridging membranes. The simulations show that synaptotagmin‐1 C2‐domains placed near the site of fusion hinder the ability of SNARE complexes to bring the membranes together ...

A Model for Predicting Magnetic Targeting of Multifunctional Particles in the Microvasculature [PDF]
, 2006 A mathematical model is presented for predicting magnetic targeting of multifunctional carrier particles that are designed to deliver therapeutic agents to malignant tissue in vivo. These particles consist of a nonmagnetic core material that contains embedded magnetic nanoparticles and therapeutic agents such as photodynamic sensitizers.

Particle Acceleration in Relativistic Magnetized Collisionless Pair Shocks: Dependence of Shock Acceleration on Magnetic Obliquity [PDF]
Astrophys.J.698:1523-1549,2009, 2009 We investigate shock structure and particle acceleration in relativistic magnetized collisionless pair shocks by means of 2.5D and 3D particle-in-cell simulations. We explore a range of inclination angles between the pre-shock magnetic field and the shock normal.

Role of Ionic Liquids in Composites in Analytical Sample Preparation
Separations, 2020 Ionic liquids (ILs) are a group of non-conventional salts with melting points below 100 °C. Apart from their negligible vapor pressure at room temperature, high thermal stability, and impressive solvation properties, ILs are characterized by their ...
