Structural biology of ferritin nanocages

open access: yesFEBS 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 ...

Study of the influence of the parameters of modern grounding wires on the value of power losses in them for overhead power lines of 330-750 kV

open access: yesElectrical engineering & Electromechanics, 2023
Introduction. The problem of estimating power losses in grounding wires with built-in fiber optic cable for overhead power lines of voltage class 330-750 kV is relevant, while it is obvious that the amount of losses depends on the chosen brand of wire ...

Reducing switching losses through MOSFET-IGBT combination [PDF]

open access: yes, 2008
This paper introduces a configuration aimed at switching losses reduction trough a power leg constructed by combining a MOSFET and an IGBT. The combined use of these different switches leads to the turn-on losses reduction trough the use of the faster ...

Power and loss aversion

open access: yesOrganizational Behavior and Human Decision Processes, 2010
Four experiments tested the prediction that power reduces loss aversion by increasing the anticipated value of gains and shrinking the negative anticipated value of losses. Experiment 1 provided initial support for the prediction that those in power are less loss averse by replicating a classic paradigm of loss aversion in riskless choice and ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS 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.
