dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Corrosion Behaviour of the Anodic Oxide Film on Commercially Pure Titanium in NaCl Environment

International Journal of Electrochemical Science, 2014
Anodic oxide growths on commercially pure titanium in 1 M sulphuric and phosphoric acids have been investigated in the present study. Ruptures and blisters of the oxide layers were found as result of a huge pressure of oxygen bubbles developed within the

Handbook of Establishing and Maintaining Oxygen‐Free Atmospheres

Advanced Engineering Materials, EarlyView.
This study presents a practical framework for creating oxygen‐free atmospheres at ambient pressure using silane‐doped inert gases. The results show that ultra‐low oxygen levels and strongly reduced water content can be achieved through controlled silane dosing, drying systems, and sensor monitoring.
