Mass Balance Evolution of Black Rapids Glacier, Alaska, 1980–2100, and Its Implications for Surge Recurrence

Frontiers in Earth Science, 2017
Surge-type Black Rapids Glacier, Alaska, has undergone strong retreat since it last surged in 1936–1937. To assess its evolution during the late Twentieth and Twenty-first centuries and determine potential implications for surge likelihood, we run a ...

Runoff‐generated debris flows: Observation of initiation conditions and erosion–deposition dynamics along the channel at Cancia (eastern Italian Alps)

Earth Surface Processes and Landforms, 2020
In the Dolomitic region, abundant coarse hillslope sediment is commonly found at the toe of rocky cliffs. Ephemeral channels originate where lower permeability bedrock surfaces concentrate surface runoff.

BMP antagonist CHRDL2 enhances the cancer stem‐cell phenotype and increases chemotherapy resistance in colorectal cancer

Molecular Oncology, EarlyView.
Overexpression of CHRDL2 in colon cancer cells makes them more stem‐like and resistant to chemo‐ and radiotherapy. CHRDL2‐high cells have upregulation of the WNT pathway, genes involved in the DNA damage response (DDR) pathway and epithelial‐to‐mesenchymal transition (EMT). This leads to quicker repair of damaged DNA and more cell migration.

Tidal Disruption of a Star By a Black Hole : Observational Signature

, 2004
We have modeled the time-variable profiles of the Halpha emission line from the non-axisymmetric disk and debris tail created in the tidal disruption of a solar-type star by a million solar mass black hole.

Downregulation of O‐GlcNAcylation enhances etoposide‐induced p53‐mediated apoptosis in HepG2 human liver cancer cells

FEBS Open Bio, EarlyView.
Etoposide, a topoisomerase II inhibitor, reduces O‐GlcNAcylation in HepG2 liver cancer cells. Further inhibition of O‐GlcNAc transferase by OSMI‐1 enhanced etoposide‐induced apoptosis, lowering the IC50 for viability and increasing the EC50 for cytotoxicity.

Emission from elliptical streams of dusty debris around white dwarfs [PDF]

arXiv, 2020
White dwarfs are routinely observed to have polluted atmospheres, and sometimes significant infrared excesses, that indicate ongoing accretion of circumstellar dust and rocky debris. Typically this debris is assumed to be in the form of a (circular) disc, and to originate from asteroids that passed close enough to the white dwarf to be pulled apart by ...

Advanced glycation end products promote the release of endothelial cell‐derived mitocytosis

FEBS Open Bio, EarlyView.
Under diabetic conditions, AGEs induce mitochondrial damage in HUVECs, activating migrasome‐mediated mitocytosis. Migrasomes encapsulate damaged mitochondria and are released into the extracellular space, facilitating intercellular mitochondrial transfer.
