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 ...

Impact of starting alumina powders on densification peculiarities of reactive-sintered YAG:Sm3+ ceramics

Open Ceramics
YAG:Sm3+ (5 at.%) transparent ceramics have been obtained by reactive sintering using different starting Al2O3 powders. Effect of particle size in the 100–400 nm range, morphology and dispersity of starting alumina powders on the properties of YAG:Sm3 ...

Effect of the Ketoprofen Distribution in Cream-gels on the Formation of the Impurities

Разработка и регистрация лекарственных средств, 2019
Introduction. The fixed combination of ketoprofen, methyl salicylate and levomenthol in the form of a cream-gel is rational. Ketoprofen forms salts with bases and esters with substances containing hydroxyl groups.

Intergrowth and thermoelectric properties in the Bi-Ca-Co-O system

, 2007
Single crystals of the Bi-Ca-Co-O system have been grown using the flux method with cooling from 900$\celsius$ and 950$\celsius$, respectively. The single crystals are characterized by transmission electron microscopy and X-ray diffraction.

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

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.

Reactive sintering of highly-doped YAG/Nd3+ :YAG/YAG composite ceramics [PDF]

Processing and Application of Ceramics, 2017
Multilayer YAG/Nd3+:YAG/YAG composite laser ceramics were obtained by the reactive sintering in vacuum. The effect of the neodymium ion concentration (1–4 at.%) on the formation of defects and optical quality of composite ceramics was studied.

Single Crystal Growth of Skutterudite CoP3 under High Pressure

, 2003
A new method to grow single crystals of skutterudite compounds is examined. Using a wedge-type, cubic-anvil, high-pressure apparatus, single crystals of CoP3 were grown from stoichiometric melts under a pressure of 3.5 GPa.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Laser ablation and photostimulated passivation of the surface of Cd1–хZnхTe crystals

Технологія та конструювання в електронній апаратурі, 2011
A new physical method of Cd1–хZnхTe-detectors passivation is proposed — the treatment of crystal surface by a laser ablation (LA) with subsequent photostimulated passivation (PhSP), during wich a high-resistance oxide layer is formed on it’s surface ...
