Intra-Annual Variability of the Surface Ablation of the Aldegondabreen Glacier (Spitsbergen)

Лëд и снег, 2023
The intra-annual variability of the surface ice ablation on the 5.5 km2 Aldegondabreen glacier (Spitsbergen Island, Barentsburg area) is presented. The ice ablation was measured during five seasons (2018–2022) at the two stakes, installed in the lower ...

Arctic Biostratigraphic Heterochroneity [PDF]

Science, 1984
Hickey et al. described the magnetic stratigraphy (not magnetic anomaly profile) and biostratigraphy of Upper Cretaceous and Lower Cenozoic sediments of the Eureka Sound Formation of arctic Canada and claimed that there is substantial heterochroneity of biostratigraphic units.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

FEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Influence of sea surface temperature in the tropics on the Antarctic sea ice under global warming

Лëд и снег, 2019
Sea ice fields in the Antarctic, in contrast to the Arctic ones, did not show a reduction in observed global warming, whereas the global climate models indicate its certain decrease.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Modernization of small-sized drying plant for searching optimal modes with thermovision control

Vestnik MGTU
The climatic features of the Murmansk region (low average annual temperature; insignificant number of sunny days) do not contribute to the effective use of natural methods of drying aquatic organisms and determine the use of artificial dehydration ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Anesthetic and analgesic management of Svalbard rock ptarmigan (Lagopus muta hyperborea) undergoing experimental stereotaxic neurosurgery

BMC Veterinary Research
Background Stereotaxic neurosurgery in animal models has become a prominent experimental technique in many areas of science and research. These approaches, however, require advanced surgical skills, meticulous anesthetic protocols, and thorough analgesic
