肾素原受体参与肾脏对体液与电解质的调节素原受体参与肾脏对体液与电解质的调节

Zhongshan Daxue xuebao. Yixue kexue ban, 2017
最初的研究发现肾素原受体（PRR）作为肾素与肾素原的特异性受体，参与对肾素-血管紧张素系统（RAS）活性的调节。然而，最新的证据揭示PRR功能的多样性，PRR可以发挥RAS依赖性与非依赖性的作用。PRR可以被furin或 ADAM19切割，产生两个功能性片段，一是28 ku可溶性PRR受体（sPRR），另一个是M8.9，后者是vacuolar H+-ATPase的一个亚型，负责H+转运。近些年的研究证明，PRR参与了许多的生理与病理生理过程的调节。比如，PRR通过调节集合管水通道-2（AQP2 ...

Hybrid Reaction–Diffusion Epidemic Models: Dynamics and Emergence of Oscillations

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we construct a hybrid epidemic mathematical model based on a reaction–diffusion system of the SIR (susceptible‐infected‐recovered) type. This model integrates the impact of random factors on the transmission rate of infectious diseases, represented by a probabilistic process acting at discrete time steps.

A PLP‐SEC Investigation of Di(Ethylene Glycol) Methyl Ether Methacrylate Radical Polymerization Propagation Kinetics in Solution

Macromolecular Reaction Engineering, EarlyView.
The propagation rate coefficient of di(ethylene glycol) methyl ether methacrylate exhibits the same temperature dependency but is a factor of 12 higher in aqueous solution compared to bulk. Smaller increases are observed in ethanol and ethanol/water mixtures, with the value of the rate coefficient decreasing as the monomer concentration in solution is ...

Calcium signaling in plant defense

New Plant Protection, EarlyView.
Calcium signaling acts as a central hub in plant immunity, translating pathogen perception into defense responses. This review highlights the channels, sensors, and signaling networks involved, and discusses how pathogens subvert calcium dynamics, as well as how this knowledge may inspire innovative strategies for engineering durable crop resistance ...

Plasmodesmata‐located proteins: The molecular hubs in noncell‐autonomous immunity

New Plant Protection, EarlyView.
Plasmodesmata serve as critical battlefields for plant immunity, regulated by diverse proteins. This article provides a comprehensive review of the regulatory mechanisms, challenges, and future directions concerning proteins located within plasmodesmata and their roles in plant defense responses.

Synergizing scientific and local knowledge for ecosystem services assessments: A case study in northern Portugal

People and Nature, EarlyView.
Abstract Integrating scientific and local ecological knowledge on ecosystem services (ES) is essential for effective and inclusive environmental management. Such an integration strengthens societal engagement, supports policy implementation and helps reduce sectoral conflicts across marine sectors.

Mapping the populist mind: A network approach to integrate sociological and psychological models of the populist radical right

Frontiers in Political Science
Who supports the populist radical right (PRR)? And under what circumstances? We theorize that social status-related envy (SSRE) is the construct that integrates personality- and grievance-based theories of PRR support.

Using Lignin and Spent Coffee Grounds as Bio‐Additives in 3D‐Printable Poly Lactic Acid/Multi‐Walled Carbon Nanotube Composites for Advanced Electronic Applications

Polymer Composites, EarlyView.
Bio‐based additives derived from lignin and spent coffee grounds (SCG) are used to enhance MWCNT dispersion in PLA composites, enabling improved electrical conductivity and reliable in material extruded strain‐gauge sensors. ABSTRACT In this work, three bio‐based additives, lignin, spent coffee grounds (SCG), and oil extracted from SCG (Ox‐SCG) were ...

3 PRRS-stabile sohold leverede hver 10 hold PRRS-fri smågrise

, 2014
I tre besætninger var det muligt at producere 10 PRRS-fri hold af smågrise i hver besætning over tid, selvom soholdet var PRRS-positivt. Dette var muligt på trods af forskelle i produktionssystemer, karantænebrug og PRRS-vaccinationsstrategier.I undersøgelsen indgik tre besætninger. Besætningerne var deklareret PRRS-positive, hvilket betyder at der var

Mapping the Research Landscape of the Correlation Between Radiotherapy and Tumor Immune Microenvironment: A Bibliometric Analysis

Precision Radiation Oncology, EarlyView.
The first bibliometric analysis of 2,584 articles revealed studies led by China on radiotherapy and tumor immune microenvironment. The analysis concluded that the research in this field has gone through three stages: mechanism exploration, clinical validation, and technological and personalized optimization.
