Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Differentiation of placenta percreta through MRI features and diffusion-weighted magnetic resonance imaging

Insights into Imaging, 2023
Objectives To identify whether parameters measured from diffusion kurtosis and intravoxel incoherent motion help diagnose placenta percreta. Methods We retrospectively enrolled 75 patients with PAS disorders including 13 patients with placenta percreta ...

Evaluating foam heterogeneity [PDF]

, 1972
New analytical tool is available to calculate the degree of foam heterogeneity based on the measurement of gas diffusivity values. Diffusion characteristics of plastic foam are described by a system of differential equations based on conventional ...

A Mass-transfer Particle-tracking Method for Simulating Transport with Discontinuous Diffusion Coefficients

, 2020
The problem of a spatially discontinuous diffusion coefficient ($D(\boldsymbol x)$) is one that may be encountered in hydrogeologic systems due to natural geological features or as a consequence of numerical discretization of flow properties.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Quasilinear reaction diffusion systems with mass dissipation

Mathematics in Engineering, 2021
<abstract><p>We study quasilinear reaction diffusion systems relative to the Shigesada-Kawasaki-Teramoto model. Nonlinearity standing for the external force is provided with mass dissipation. Estimate in several norms of the solution is provided under the restriction of diffusion coefficients, growth rate of reaction, and space dimension ...

MASS TRANSFER EFFECTS ON ACCELERATED VERTICAL PLATE IN A ROTATING FLUID WITH FIRST ORDER CHEMICAL REACTION [PDF]

Journal of Mechanical Engineering and Sciences, 2012
The precise analysis of the rotation effects on the unsteady flow of an incompressible fluid past a uniformly accelerated infinite vertical plate with variable temperature and mass diffusion has been undertaken, in the presence of a homogeneous first ...

Spurious diffusion in particle simulations of the Kolmogorov flow

, 2001
Particle simulations of the Kolmogorov flow are analyzed by the Landau-Lifshitz fluctuating hydrodynamics. It is shown that a spurious diffusion of the center of mass corrupts the statistical properties of the flow.

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.
