Unraveling the Bioactive Compounds and Multi-Target Mechanisms of the Fructus Aurantii Immaturus-Bambusae Caulis in Taeniam Herb Pair Against Chronic Gastritis: Integrating Identification of Absorbed Constituents, Targeted Network Pharmacology, and Computational Validation. [PDF]

open access: yesFood Sci Nutr
This work systematically explored the anti‐chronic gastritis mechanism of the FAI‐BCT herb pair. UPLC‐Q‐TOF‐MS/MS was applied to identify absorbed prototypes and metabolites of FAI‐BCT in rat plasma. Combining database mining, network pharmacology, molecular docking, and molecular dynamics simulation, we screened the key bioactive components and core ...

A Framework for Emergency Department-Integrated Hepatitis C Test-and-Treat in the United States. [PDF]

open access: yesJ Viral Hepat
ABSTRACT Despite the availability of curative, direct‐acting antiviral therapy, hepatitis C virus elimination remains incomplete. Losses across the care cascade continue to limit impact, from initial diagnosis to sustained virologic response. Fewer than 1/3 of individuals ultimately achieve cure. These gaps reflect a delivery system that does not align

Ultra-Low-Temperature Refrigeration Systems: A Review and Performance Comparison of Refrigerants and Configurations

open access: yesEnergies, 2023
During the last decade, many industrial and medical applications have shown a requirement for low-temperature-cooling usage (from −40 to −80 °C), which cannot be efficiently obtained via the conventional refrigeration systems usually employed for medium ...

Experimental investigation of the performance of a single-stage auto-cascade refrigerator [PDF]

open access: yesHeat and Mass Transfer, 2015
Auto-refrigerating cascade (ARC) systems possess many advantages comparing with traditional cascade refrigeration systems. This work proposed a novel ternary mixture, R600a/R23/R14, for ARC systems for 190 K applications. The performance of the ternary mixture and the influences of compositional ratio and bypass scheme were assessed in a modified ...

Experimental Study of the effects of Throttle valve on Auto-cascade Refrigeration System [PDF]

open access: yesProceedings of the 3rd International Conference on Material, Mechanical and Manufacturing Engineering, 2015
The objection of this article is to optimize auto-cascade refrigeration system. This refrigeration system use multiple mixture (R22/R23/R14) as the refrigerant, which is driven by the single-stage compressor. Throttle is an important composition of auto-cascade refrigerant system, which impact on evaporation temperature and refrigeration efficiency ...

The Relation of Performance Parameters for a 150K Auto-Cascade Refrigeration System

open access: yesResearch Journal of Applied Sciences, Engineering and Technology, 2013
The performance parameters of a single compressed and four-stage segregating auto-cascade refrigeration system were developed in this study. The temperature of the cryogenic tank went down relatively slow with the evaporating temperature and the refrigerant temperature for W. When the state of system is steady, the suction pressure of the compressor is

Spray‐Dried Engineered Escherichia coli Whole‐Cell Biocatalysts Enable Cell Recycling and In Vivo α‐Ketoglutarate and NADPH Regeneration for Efficient Codeine Manufacture

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT A recombinant whole‐cell biocatalytic approach provides several advantages over isolated enzymes, such as improved enzyme stability, in vivo cofactor regeneration, and the facilitation of cascade reactions within a single cell. Whole‐cell biocatalysis has gained attention in medicinal opioid production, due to its technical and economic ...

From Material Tensions to Organizational Paradoxes: How Manufacturers Cope With the Limits of Circular Product Design

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...
