U-Pb ISOTOPIC GEOCHRONOLOGY OF THE MONAZITE GNEISSES OF THE «ZELENOLEVADIVSKA SUITE» OF THE MIDDLE BUG REGION

Геологія і корисні копалини Світового океану, 2022
On the right bank of the South Bug river valley, opposite the village of Zelena Levada crystalline rocks are observed in separate scattered rock outcrops, more than 1 km long along the river bed. A bundle of hypersthene-biotite and biotite plagiogneisses

Identification and Characterization of an In Silico Designed Membrane‐Active Peptide with Antiviral Properties

Advanced Science, EarlyView.
An evolutionary molecular dynamics platform is used to design P1.6, a membrane‐active peptide that senses lipid packing defects in viral envelopes. P1.6 adopts a stabilized α‐helical structure upon membrane contact, disrupts virus‐like liposomes, and damages HIV‐1 particles.

A DNA Tetrahedron Delivery Asiatic Acid to Reprogram Mitochondrial Metabolism for Promoting Bone Regeneration via STAT3 Phosphorylation

Advanced Science, EarlyView.
A hyaluronic acid methacrylate (HAMA) hydrogel incorporating DNA tetrahedrons loaded with Asiatic acid (TDN@AA) was developed. HM‐TDN@AA promotes angiogenesis of endothelial cells (ECs), inhibits osteoclastogenesis from bone marrow–derived macrophages (BMDMs), and enhances osteogenesis of mesenchymal stem cells (MSCs) via STAT3‐mediated mitochondrial ...

Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

Advanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.

IRAS 05358+3543: Multiple outflows at the earliest stages of massive star formation [PDF]

, 2002
We present a high-angular-resolution molecular line and millimeter continuum study of the massive star formation site IRAS 05358+3543. The most remarkable feature is a highly collimated (collimation factor ~10) and massive (>10 M_sun) bipolar outflow of ...

Circular Potential of Lithium‐Ion Battery Recycling Slags: Quantifying Microstructure and Elemental Distribution for a Holistic Valorization

Advanced Science, EarlyView.
A lithium‐bearing slag is investigated with the goal of holistic valorization. The present β‐eucryptite (LiAlSiO4) exhibits a high lithium content and low levels of impurities. The spinel contains most of the chromium and vanadium, representing additional valorization opportunities.

On the so-called “leukogranulite formation” and “greenlevada suite” of Early Precambrian of the Ukrainian Shield

Геофизический журнал, 2018
It has been shown using as an example the geological structure of the Precambrian basement of the Middle Bug area (the Ukrainian Shield) that the chronostratigraphic scheme of the Lower Archean needs to be modified, in particular, greenlevada suite of ...
