Online immunocapture ICP-MS for the determination of the metalloprotein ceruloplasmin in human serum

BMC Research Notes, 2018
Objective The human copper-protein ceruloplasmin (Cp) is the major copper-containing protein in the human body. The accurate determination of Cp is mandatory for the reliable diagnosis of several diseases.

Controllability study of copper‐tin‐sulphide (Cu3SnS4) material based on the ratio adjustment of Cu to Sn elements

Micro & Nano Letters, 2023
The synthesis of pure phase Cu3SnS4 is of great significance for improving its material properties. Here, the control law of Cu and Sn element ratio on the synthesis of pure phase Cu3SnS4 from physical and chemical methods was analyzed through literature

In vivo evidence for glycyl radical insertion into a catalytically inactive variant of pyruvate formate‐lyase

FEBS Letters, EarlyView.
Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Feasibility Study on Laser Powder Bed Fusion of Ferritic Steel in High Vacuum Atmosphere

Journal of Manufacturing and Materials Processing
The boiling point of metals is dependent on the ambient pressure. Therefore, in laser-based fusion welding and additive manufacturing processes, the resulting process regime, ranging from heat conduction welding to the keyhole mode, is also influenced by

P‐glycoprotein modulates the fluidity gradient of the plasma membrane of multidrug resistant CHO cells

FEBS Letters, EarlyView.
To explore the impact of the overexpression of the multidrug‐transporter P‐glycoprotein (ABCB1) on membrane fluidity, we compared the transversal gradient of mobility and microviscosity in plasma membranes of drug‐sensitive Chinese hamster ovary cells (AuxB1) and their multidrug‐resistant derivatives (B30) using the fluorescent n‐(9‐anthroyloxy) fatty ...

Impact of the Process Parameters, the Measurement Conditions and the Pre-Machining on the Residual Stress State of Deep Rolled Specimens

Journal of Manufacturing and Materials Processing, 2019
Mechanical surface treatments, e.g., deep rolling, are widely spread finishing processes due to their ability to enhance the fatigue strength of the treated materials with means of cold working and inducement of favorable compressive residual stresses ...
