Hydrogen trapping at precipitates in Ni-based superalloy 718 (A first-principles study)

Mechanical Engineering Journal
Hydrogen segregation to strengthening precipitates (γ′′, γ′, and δ) is often invoked to explain hydrogen embrittlement (HE) in Ni-based superalloy 718 (Alloy718); however, its quantitative significance remains insufficiently validated.

Ba0.5Sr0.5Co0.8Fe0.2O3–δ–La0.6Sr0.4Co0.8Fe0.2O3–δ Composite Cathode for Solid Oxide Fuel Cell

Archives of Metallurgy and Materials, 2016
Composite cathodes contain Ba0.5Sr0.5Co0.8Fe0.2O3–δ and La0.6Sr0.4Co0.8Fe0.2O3–δ were tested in different configuration for achieving cathode of area specific resistance lower than Ba0.5Sr0.5Co0.8Fe0.2O3–δ and La0.6Sr0.4Co0.8Fe0.2O3–δ cathodes ...

Late Pliocene benthic δ¹³C and δ¹⁸O from ODP Site 959 and δ13C from ODP Site 662 in the eastern equatorial Atlantic

, 2020
We present high-resolution late Pliocene (~2.7-3.5 Ma) benthic foraminiferal stable isotope records from eastern equatorial Atlantic ODP Site 959 (δ^13^C and δ^18^O) and ODP Site 662 (δ^13^C).

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

FEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

Distinct transformation mechanisms of proteinaceous materials to low-molecular-weight NOCs during combustion of different biomass fuels

Atmospheric Environment: X
Low-molecular-weight nitrogen-containing organic compounds (LMW NOCs) from biomass burning (BB) significantly influence aerosol chemistry, yet their fuel-dependent molecular signatures and formation pathways remain poorly understood.

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

FUNGSI DAN PEMERIKSAAN LIMFOSIT γδT (Functions and Examination of γδT lymphocytes)

INDONESIAN JOURNAL OF CLINICAL PATHOLOGY AND MEDICAL LABORATORY, 2018
T lymphocytes most have TCR α and β chains. However, TCR formed from γ and δ chains determine a new subset of T lymphocytes. γδTCR specific to different types of ligands, including bacterial phosphoantigen, nonclassical MHC-I molecules and unprocessed protein.

Combination of Novozym 435-catalyzed enantioselective hydrolysis and amidation for the preparation of optically active δ-hexadecalactone [PDF]

, 2015
A new enzymatic method for synthesis of enantiomerically enriched δ-hexadecalactone (3) based on the enzymatic kinetic resolution of N-methyl-5-acetoxyhexadecanamide (1) is described.

Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus

FEBS Open Bio, EarlyView.
BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

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 ...
