A Single-Chain Peptide Probe Targeting Pathological Collagen for Precise Staging of Hepatic Fibrosis by MR Imaging.

Hepatic fibrosis, a chronic liver response to injury with potential severe outcomes like cirrhosis and liver cancer, necessitates urgent noninvasive diagnostic techniques to halt disease progression. We herein for the first time developed a single-chain peptide probe targeting pathological collagen for in vivo magnetic resonance imaging (MRI) of hepatic fibrosis. The novel (GhypO) probe, distinguished by its unique monomeric conformation achieved through Pro to (2,4)-hydroxyproline (hyp) substitution and subsequent disruption of hydrogen bonding, exhibits selectivity for pathological collagen over its intact counterpart in connective tissues.

A Green Computing Business Aggregation Strategy for Low Earth Orbit Satellite Networks.

This paper proposes a green computing strategy for low Earth orbit (LEO) satellite networks (LSNs), addressing energy efficiency and delay optimization in dynamic and energy-constrained environments. By integrating a Markov Decision Process (MDP) with a Double Deep Q-Network (Double DQN) and introducing the Energy-Delay Ratio (EDR) metric, this study effectively quantifies and balances energy savings with delay costs. Simulations demonstrate significant energy savings, with reductions of up to 47.

Research on Stability of Removal Function in Figuring Process of Mandrel of X-Ray-Focusing Mirror with Variable Curvature.

Over the past 30 years, researchers have developed X-ray-focusing telescopes by employing the principle of total reflection in thin metal films. The Wolter-I focusing mirror with variable-curvature surfaces demands high precision.

Preparation of Green Tea Polyphenol-Loaded Diacylglycerol Nanostructured Lipid Carrier Hydrogels and Their Activities Related to Skin Protection.

Diacylglycerol (DAG) is a functional oil but is rarely used in the cosmetic industry because low solubility, susceptibility to leakage and low viscosity to skin are still the main hurdles. A novel diacylglycerol nanostructured lipid carrier hydrogel (GTP-DAG-NLC-GEL) loaded with green tea polyphenol (GTP) was designed and successfully prepared to broaden DAG's application in cosmetics, which significantly improved GTP stability and skin stickiness of DAG. The results showed that DAG-NLC-GEL had good viscosity, which was 980 Pa·s when the shear rate was 5 rpm, and its viscosity decreased quickly with the increase in shear rate, making it easily expand on skin.

Hepatic and intestinal insights into the molecular mechanisms of dietary Antarctic krill-induced body color differentiation in Plectropomus leopardus.

Antarctic krill (Euphausia superba), which is rich in astaxanthin, has been widely utilized as a dietary supplement in fish aquaculture. Our study was to feed juvenile leopard coral grouper (Plectropomus leopardus) a diet containing 50 % Antarctic krill, revealing significant body color differentiation between a reddened group (BKR) and a non-reddened group (BKB), followed by comparative analysis with the control group (BCon) without krill supplementation. Histological analysis and carotenoid content in the liver and intestine were differentially regulated in color-differentiated individuals.

Enhanced healing of MRSA-infected wounds with okara cellulose nanocrystals-based temperature-sensitive cationic hydrogel: Development and characterization.

The development of functional hydrogel dressings with robust mechanical properties has posed a significant challenge in expediting the healing process of MRSA-infected wounds. To address this, a composite hydrogel, comprising carboxylated soybean cellulose nanocrystals (CNCs), poly(N-isopropyl acrylamide) (PNIPAM), dimethyl diallyl ammonium chloride (PDADMAC), and kaolin (CN/P-K) was synthesized. CNCs served to stabilize the interpenetrating polymer networks of PNIPAM and PDADMAC through hydrogen bonding and electrostatic interactions, respectively, while the kaolin interlayer improved the material toughness.
