Endothelial PDGF Signaling Dysregulation Impairs Testicular Interstitial Homeostasis in Diabetes

open access: yesAdvanced Science, EarlyView.
Testicular endothelial cells (TECs) function as central signaling hubs that coordinate interstitial homeostasis. Diabetes disrupts TEC‐derived PDGF signaling, silences the JUND‐MCL1 survival program in Leydig cells, and impairs peritubular function, leading to fibrosis and testosterone insufficiency.

Sea ice concentration estimates from ICESat-2 linear ice fraction – Part 1: Multi-sensor comparison of sea ice concentration products [PDF]

open access: yesThe Cryosphere
Sea ice coverage is a key indicator of changes in polar and global climate. Observational estimates of the area and extent of sea ice are primarily derived from passive microwave surface emissions, which are used to develop gridded products of sea ice ...

Tailored Porous Bimetallic Nanozyme Platform for Full‐Cycle Therapeutics of Intestinal Ischemia/Reperfusion

open access: yesAdvanced Science, EarlyView.
ABSTRACT Intestinal ischemia/reperfusion (I/R) injury presents a biphasic pathology: an acute oxidative‐inflammatory phase leading to organ failure, and a recovery phase marked by mucosal dysfunction and bacterial translocation. The developed MPB@TA‐Cu‐Ma nanocomposite functions as a dual‐phase therapeutic platform with significant efficacy. It rapidly
