Stratigraphy and paleontology (plant and arthropod fossils) from the Late Neogene Niguanak site, Arctic Slope, Northern Alaska

open access: yesArctic, Antarctic, and Alpine Research
Motivated by the need for more paleodata for Pliocene paleoclimate data-model comparison, we revisited unpublished investigations of a fossiliferous site on the Niguanak River in Arctic North America. Analyses of the samples indicates forested conditions

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma

open access: yesFEBS Open Bio, EarlyView.
GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

The influence of sedimentation rate and sedimentary facies on organic matter enrichment in source rocks in the Lufeng Sag, Pearl River Mouth Basin, South China Sea

open access: yesFrontiers in Earth Science
IntroductionOrganic matter enrichment in the source rocks of rift lacustrine basins is crucial for the formation of oil and gas, and sedimentation rates and sedimentary environments are two important factors influencing organic matter enrichment ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Stratigraphy and sedimentary environments of the Villa María and Peña Colorada formations (Paleogene), Westernmost Argentine Plateau.

open access: yesLatin American Journal of Sedimentology and Basin Analysis, 2021
The Peña Colorada Formation records the early stage of Andean foreland sedimentation over ~1,000 km2 in the north westernmost Argentine plateau (21°51’ S - 66°12’ W).

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

open access: yesFEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Sedimentation environment in the Tatar Strait of the Sea of Japan

open access: yesBulletin of Kamchatka Regional Association «Educational-Scientific Center». Earth Sciences
High-resolution seismoacoustic data were obtained in the central Tatar Straight of the Sea of Japan in 59-th cruise of Research Vessel «Akademik M.A Lavrentiev» conducted as a part of the international «Sakhalin Slope Gas Hydrates» project in the summer of 2012. The data was used to identify types of reflecting signals echotypes, map their distribution

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

open access: yesFEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...
