Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

Advanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

Development and Optimization of an ELISA to Quantitate C3(H2O) as a Marker of Human Disease

Frontiers in Immunology, 2019
Discovery of a C3(H2O) uptake pathway has led to renewed interest in this alternative pathway triggering form of C3 in human biospecimens. Previously, a quantifiable method to measure C3(H2O), not confounded by other complement activation products, was ...

Mutations in complement C3 from aHUS patients [PDF]

Blood, 2015
In this issue of Blood, Schramm et al demonstrate that the majority of mutations in complement C3 identified in atypical hemolytic uremic syndrome (aHUS) patients cause dysregulation in the alternative pathway of complement.

Defining the Complement Biomarker Profile of C3 Glomerulopathy [PDF]

Clinical Journal of the American Society of Nephrology, 2014
C3 glomerulopathy (C3G) applies to a group of renal diseases defined by a specific renal biopsy finding: a dominant pattern of C3 fragment deposition on immunofluorescence. The primary pathogenic mechanism involves abnormal control of the alternative complement pathway, although a full description of the disease spectrum remains to be determined.

Defects Dynamic in Photo‐Excited CeO2 and their Influence on CO2 Photoreduction

Advanced Functional Materials, EarlyView.
X‐ray photoelectron spectroscopy study under light excitation is presented to track the defect dynamic (Ce4+ to Ce3+) in CeO2. Surface enhanced Raman spectroscopy confirmed the key role of Ce3+ states in controlling charge and energy transfer across the CeO2‐dye molecule interface.

Specific Evolution and Gene Family Expansion of Complement 3 and Regulatory Factor H in Fish

Frontiers in Immunology, 2020
The complement system comprises a large family of plasma proteins that play a central role in innate and adaptive immunity. To better understand the evolution of the complement system in vertebrates and the contribution of complement to fish immunity ...

Humán dendritikus sejtek működésének szabályozása komplementfehérjék és receptoraik által; exosomák jelentősége a T-sejt válasz kialakításában = Regulation of the function of dendritic cells by complement proteins and receptors; the role of exosomes in the development of T-cell response [PDF]

, 2011
A dendritikus sejtek (DC-k) érését számos stimulus indukálja, mint például a gyulladásos körülmények vagy mikrobiális termékek jelenléte. A szervezetbe kerülő antigén a komplementrendszer aktiválódása következtében opszonizált formában van jelen, ami az
