Sedimentation

open access: yes, 2023
Focus: To understand the role of sedimentation in creating the unique conditions of ocean floor ecosystems. Learning objectives: With this activity, pupils will gain a basic understanding of how sediments in the ocean settle on the ocean floor ...

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

open access: yesFEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly

Ionomycin suppresses cancer cell growth by disrupting mitochondrial transcription

open access: yesFEBS Open Bio, EarlyView.
In this study, we identify a new function for the selective Ca2+ ionophore, ionomycin, as an inhibitor of mitochondrial transcription. Both total and nascent RNA analyses revealed that ionomycin treatment reduces the transcription of mitochondrial genes.

The influence of syn‐depositional compaction on clastic sediment distribution in river‐dominated deltas: A modelling study

open access: yesThe Depositional Record
Syn‐sedimentary compaction or consolidation is an important process in deltaic environments because it affects both the local morphodynamics and hydrodynamics as well as the delta‐scale accommodation space.

Exploring the influence of lactoferrin on wound healing and related signaling pathways: a systematic review

open access: yesFEBS Open Bio, EarlyView.
Lactoferrin promotes wound healing by activating MAPK, PI3K/Akt, and extracellular matrix pathways, enhancing fibroblast remodeling, proliferation, and re‐epithelialization. These mechanisms highlight its therapeutic potential in inflammation control, tissue repair, and remodeling.

Sedimentation of large particles in turbulent environments

open access: yes, 2015
The aim of the present study is to investigate the sedimentation of large non-colloidal spherical particles in both quiescent and turbulent environments. To this aim, Direct Numerical Simulations are performed using an Immersed Boundary Method to account

Tertiary tectonics and sedimentation history of the Sarawak basin, east Malaysia [PDF]

open access: yes, 1996
A seismic stratigraphic study of the regional lines for the offshore Sarawak area was undertaken with the aim of understanding the tectonics and sedimentation history of the hydrocarbon prolific Sarawak Basin.

Autogenic Sedimentation in Clastic Stratigraphy

open access: yes, 2017
Internally generated, or autogenic, terrestrial and marine sediment-transport dynamics can produce depositional patterns similar to those associated with climatic, tectonic, or sea level changes.

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

SEDIMENTATION OF LOCHKOVIAN-LOWER EMSIAN VOLCANOKLASTIC DEPOSITS OF THE WEST-MAGNITOGORSK ZONE OF THE SOUTH URAL

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2018
The relevance of research. The Early Devonian stage of formation of the Magnitogorsk island-arc system remains poorly understood, despite the long history of research and rather large amount of data obtained.
