A High‐Throughput AngioPlate Platform with Integrated AngioTEER for Modeling and Monitoring Renal Proximal Tubule Injury

Advanced Materials Technologies, EarlyView.
Renal tubular injury is a major contributor to kidney disease, yet remains poorly understood due to the lack of predictive models. This study presents a high‐throughput 3D renal proximal tubule model on the AngioPlate platform integrated with automated TEER measurements (AngioTEER), enabling real‐time monitoring of drug‐induced nephrotoxicity ...

Aprotinin in severe acute pancreatitis

International Journal of Clinical Practice, 2010
Aprotinin, a Kunitz protease inhibitor, has a wide inhibitory action with particular activity against trypsin, chymotrypsin and kallikrein, making it theoretically attractive in ameliorating the effects of acute pancreatitis. Its use in acute pancreatitis has been studied for the last 50 years with disappointing results.

Is There a Surgical Role for Topical Aprotinin? [PDF]

Anesthesiology, 2008
To the Editor:—Two classes of intravenous drugs are commonly used in the perioperative setting to mitigate bleeding after cardiac surgery: lysine analogs (e.g., aminocaproic acid, tranexamic acid) and serine protease inhibitors (e.g., aprotinin).

Capsaicin Alleviates Autophagy‐Lysosomal Dysfunction via PPARA‐Mediated V‐ATPase Subunit ATP6V0E1 Signaling in 3xTg‐AD Mice

Advanced Science, EarlyView.
Capsaicin enhances lipid metabolism, reduces lipid deposition, and alleviates AD‐related pathologies. Capsaicin activates PPARA, promoting the expression of PPAR signaling pathway‐related genes and accelerating lipid metabolism. Capsaicin upregulates ATP6V0E1‐V‐ATPase‐mediated lysosomal acidification, enhancing lipid droplet clearance. PPARA is the key

Phosphorylation of CLEC-2 is dependent on lipid rafts, actin polymerization,secondary mediators, and Rac [PDF]

, 2010
The C-type lectin-like receptor 2 (CLEC-2)activates platelets through Src and Syk tyrosine kinases via a single cytoplasmic YxxL motif known as a hem immunoreceptor tyrosine-based activation motif (hemITAM).Here, we demonstrate using sucrose gradient ...

A Genetically Encoded Biosensor for Characterizing Transport and Metabolism of Glutarate

Advanced Science, EarlyView.
Here, a genetically encoded glutarate biosensor, Glusor, is developed based on transcriptional regulator CsiR. Glusor can quantify glutarate concentrations with good accuracy and precision. Then, the role of KgtP and YnfM are identified and characterized by using Glusor. Glusor also allows glutarate spatiotemporal resolution in live cells, facilitating

Divergent Inhibitor Susceptibility among Airway Lumen-Accessible Tryptic Proteases. [PDF]

PLoS ONE, 2015
Tryptic serine proteases of bronchial epithelium regulate ion flux, barrier integrity, and allergic inflammation. Inhibition of some of these proteases is a strategy to improve mucociliary function in cystic fibrosis and asthmatic inflammation.
