Tree shrew model of early diabetic retinopathy reveals microvascular dysfunction and identifies phosphoserine aminotransferase 1 as a novel therapeutic target

Animal Models and Experimental Medicine, EarlyView.
We developed an animal model of early diabetic retinopathy (DR) in the tree shrew by feeding a high‐fat and high‐sugar diet in combination with STZ. Physiological and biochemical index detection, hematoxylin and eosin staining, and transmission electron microscopy were performed to examine DR.

Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Ultrasound–Calcination Synergistic Control of (Ce, La)PO4 Catalyst Structure for Enhanced Low‐Temperature NH3‐SCR Performance

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, (Ce, La)PO4 catalysts were synthesized via an ultrasound‐assisted method. The effects of ultrasound duration and calcination temperature on the low‐temperature NH3‐SCR performance were systematically investigated. The results indicated that the (Ce, La)PO4 catalyst prepared with an ultrasound treatment time of 20 min and a ...

Experimental Study on the Enhancement of Heat Transfer Performance in Sintered‐Core Heat Pipes Using CuO Nanofluid

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study presents the design and construction of an experimental system for evaluating the thermal performance of heat pipes, using sintered‐wick heat pipes charged with CuO nanofluids. The device used in this study is a sintered‐wick heat pipe, in which the liquid return is driven by capillary forces within the porous wick structure.

Microstructural modelling of creep crack growth from a blunted crack [PDF]

, 1998
The effect of crack tip blunting on the initial stages of creep crack growth is investigated by means of a planar microstructural model in which grains are represented discretely. The actual linking-up process of discrete microcracks with the macroscopic

Cavitation resistance of refractory coatings

In this study, the resistance to the cavitation effect of three types of refractory samples based on talc with the addition of 10%, 15% and 20% cordierite was investigated. Talc has a fine structure, low hygroscopicity, insensitivity to temperature changes, low coefficient of thermal conductivity, low coefficient of linear thermal expansion, great ...

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

The Unsteady, Dynamic Characterization of Hydraulic Systems with Emphasis on Cavitation and Turbomachines [PDF]

, 1978
The ability to analyze and model the unsteady, dynamic response of hydraulic systems has arisen from the need for operational stability, flexibility and controlled transient behavior.
