Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

A microscopic model for chemically-powered Janus motors
, 2016 Very small synthetic motors that make use of chemical reactions to propel themselves in solution hold promise for new applications in the development of new materials, science and medicine. The prospect of such potential applications, along with the fact

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Microscopic study of 117Te isotope using projected shell model [PDF]
EPJ Web of ConferencesA microscopic analysis of the nuclear structure of the odd-mass 117Te has been carried out using the theoretical framework of the Projected Shell Model (PSM). The tellurium isotopes lie in a transitional region near the closed proton shell at Z=50, where

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Three-dimensional multi-mechanism bounding surface model for sands
Yantu gongcheng xuebao, 2017 Within the multi-mechanism framework, a novel constitutive model for sands is proposed based on the critical state and bounding surface plasticity theories. The model assumes that the macroscopic deformation behavior of sands can be obtained by summation

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

DEM investigation of weathered rocks using a novel bond contact model
Journal of Rock Mechanics and Geotechnical Engineering, 2015 The distinct element method (DEM) incorporated with a novel bond contact model was applied in this paper to shed light on the microscopic physical origin of macroscopic behaviors of weathered rock, and to achieve the changing laws of microscopic ...
