Financial Distress Risk and Stock Price Crashes [PDF]

SSRN Electronic Journal, 2019
This study uses 462,678 monthly observations of US-listed firms for the period 1990-2018 to document a strong positive relationship between short-term changes in financial distress risk and future stock price crashes. This result is economically significant as a one interquartile increase of the main explanatory variable in any month increases the ...

Surfaceome Reprogramming of Stemsomes Promotes Lung Cancer Targeting via Potentiated Receptor–Ligand Interactions

Advanced Science, EarlyView.
This study presents a surfaceome‐reprogramming strategy for mutation‐independent lung cancer therapy by repurposing dexamethasone to prime mesenchymal stem cell‐derived nanovesicles. The engineered vesicles leverage multi‐valent interactions mediated by upregulated adhesion proteins, EPHA2, and NOTCH3.
