Erosion and Sedimentation

Eos, Transactions American Geophysical Union, 1971
Research activities in erosion and sedimentation processes have expanded broadly during the past several years and have kept pace with generally accelerated developments in all phases of hydrology and water resources investigations.

The therapeutic opportunities and pitfalls of using iron ion chelators to treat neurodegenerative diseases

FEBS Letters, EarlyView.
Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).

Assessing the effects of model parameter assumptions on surface-wave inversion resultsKey points

Earthquake Science
Surface-wave inversion is a powerful tool for revealing the Earth’s internal structure. However, aside from shear-wave velocity (vS), other parameters can influence the inversion outcomes, yet these have not been systematically discussed.

Identification of the plant mitochondrial OrfX protein: A mass spectrometry approach

FEBS Letters, EarlyView.
The mitochondrial genome of plants contains an open reading frame, orfx, which encodes a rare protein that has so far escaped mass spectrometric detection. The protein resembles the c‐subunit of bacterial twin‐arginine‐motif‐dependent protein translocases (TatC).

Type Specimens of the Species of the Genus Papillicalymene (Arthropoda, Trilobita) from Ukraine Described by Leonid Konstantynenko

Zoodiversity
The article presents diagnoses and information on the type series of two trilobite species of the genus Papillicalymene Shirley, 1936: P. dnistroviana Konstantynenko, 2006 and P. sokoliana Konstantynenko, 2006 from the Ludlow (Upper Silurian) of Podillia

Detailed seismic velocity of the incoming subducting sediments in the 2004 great Sumatra earthquake rupture zone from full waveform inversion of long offset seismic data

Geophysical Research Letters, 2017
The nature of incoming sediments defines the locking mechanism on the megathrust, and the development and evolution of the accretionary wedge. Here we present results from seismic full waveform inversion of 12 km long offset seismic reflection data ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Characterization of Deformation Driven by the South-to-North Water Diversion and Extreme Rainfall Along the Taihang Piedmont Using Time-Series InSAR

Remote Sensing
Long-term groundwater overexploitation in the North China Plain has triggered severe land subsidence. Meanwhile, the implementation of the Middle Route of the South-to-North Water Diversion (SNWD) project and extreme precipitation events driven by ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.
