Depositional environments of the northeastern Yenisey-Khatanga sedimentary cover in relation to assessment of hydrocarbon prospects

Известия высших учебных заведений: Геология и разведка
Background. Although the recent years have seen a significant increase in the amount of geological and geophysical data on the oil and gas potential of the Yenisei-Khatanga trough, no notable hydrocarbon discoveries have been made within its northeastern

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Сomposition and structure features of the Vikulov productive deposits (Krasnoleninsky arch) and their influence on reservoir properties

Georesursy
Both sedimentological factors and secondary processes of lithogenesis influenced the formation of porosity and permeability properties of the reservoir rocks of the Vikulov suite of the Krasnoleninskoe field.

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Cyclicity, sedimentation environments and the influence of post-sedimentary processes on the structure and formation of the Vanavara Formation reservoir (based on the analysis results of core material of the novo-Yudokon field)

Georesursy
The Lower Vendian oil and gas bearing play is one of the main ones in the Siberian platform and dominant within large tectonic elements (Nepa-Botuoba anteclise, Sayan-Yenisei syneclise, etc.).

Tectono-Sedimentary Evolution of the Cenozoic Basins in the Eastern External Betic Zone (SE Spain)

Geosciences, 2020
Four main unconformities (1–4) were recognized in the sedimentary record of the Cenozoic basins of the eastern External Betic Zone (SE, Spain). They are located at different stratigraphic levels, as follows: (1) Cretaceous-Paleogene boundary, even if ...

Collective Movement of Sediment in Littoral Environment

Coastal Engineering 1968, 1968
Collective movements of sediment occur in the form of sand waves m the nearshore zone and affect beach topography to a significant extent. Bar-type sand waves move only in the onshore direction and account for various accretive profiles on the subaerial beach.

Fighting Through Community Participation Based on Vegetative Conservation Approach of Wonogiri Reservoir Sedimentation in Sub - Watershed of Keduang [PDF]

, 2012
Humans are the main trigger factors causes of sedimentation. It’s happened because of the farming and cultivation system that is not based on the principles of sustainable development. These human activities causes in damage to the environment in the
