Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Determination of Carbon in Aerosol by X-Ray Fluorescence Spectrometry

Analytical Sciences, 1988
Carbon concentration in aerosol samples was determined by X-ray fluorescence spectrometry using a synthetic multilayers crystal (W/C, 2d=16.0nm) as an analyzer. X-Ray fluorescence is an excellent method because of its handiness and non-destructive nature as well as the simultaneous determination of a number of elements with low and high atomic numbers ...

Chemical analysis of argon-oxygen decarburization slags in stainless steelmaking process by X-ray fluorescence spectrometry

, 2010
A quantitative analysis method of fluorine in the slags produced in the stainless argon-oxygen decarburization (AOD) process by X-ray spectrometry was proposed employing direct analysis technique by pressed pellet. This research investigated the separate

Selective elimination of quiescent cancer cells by dequalinium chloride via ROS‐mediated ferroptosis

FEBS Open Bio, EarlyView.
Dequalinium chloride (DQ) selectively eliminates quiescent cancer cells (QCCs) by amplifying mitochondrial ROS. QCCs exhibit elevated basal ROS and limited redox‐buffering capacity, making them vulnerable to further ROS increases. DQ‐induced ROS exceeds the tolerance threshold, triggering lipid peroxidation and ferroptosis, whereas proliferating cells ...

Local and Integral Techniques in Metal Compositional Analysis of Archaeological Objects with Surface Corrosion Layers and Small Sample Quantities

Поволжская археология, 2018
The paper presents the difference of three varied methods which have been used to analyze archaeological metals: X-ray fluorescence analysis – XRF (X-ray spectrometer), energy dispersive X-Ray microanalysis – EDAX (electron microscopy), and inductively ...

Density Measurement of Irradiated and Nonirradiated Zirconium Oxide by Ptychographic X‐Ray Computed Tomography (PXCT)

Advanced Engineering Materials, EarlyView.
Mass density governs the protective behavior of oxide layers on nuclear fuel cladding. Ptychographic X‐ray computed tomography measures zirconium oxide grown on Zircaloy‐4 under reactor and autoclave conditions, revealing nearly identical bulk densities of 5.1 ± 0.80 g cm−3.

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

Advanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

Metal and Complementary Molecular Bioimaging in Alzheimer’s Disease

Frontiers in Aging Neuroscience, 2014
Alzheimer’s disease (AD) is the leading cause of dementia in the elderly. AD represents a complex neurological disorder which is best understood as the consequence of a number of interconnected genetic and lifestyle variables, which culminate in multiple
