Complement proteins changes in ischemic stroke patients and their relation to outcome

Immunobiology
We studied plasma levels of complement system factors C1q, C2, C3, C3b, C4, C4b, C5, C5a, C9 of 84 patients with ischemic stroke within 24 h from onset of symptoms and on seventh day after admission, using Luminex immunoassay.

L'arbre qui cache la forêt

The Pan African Medical Journal, 2015
Le lupus est une pathologie chronique, qui évolue par poussées. Son expression clinique est très polymorphe et chaque symptôme peut être inaugural. Il peut débuter dès l'enfance, ces formes sont rares et de pronostic sévère.

Expression of functional recombinant von Willebrand factor-A domain from human complement C2: a potential binding site for C4 and CRIT.

Biochemical Journal, 2005
CRIT (complement C2 receptor inhibitor trispanning) is a newly described transmembrane molecule that is capable of binding C2 via its first extracellular domain (ed1). CRIT competes with C4b for the binding of C2. Previous experiments have suggested that

Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth

Advanced Functional Materials, EarlyView.
Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

A novel type II complement C2 deficiency allele in an African-American family.

Journal of Immunology, 1998
A 9-yr-old African-American male presenting with severe recurrent pyogenic infections was found to have C2 deficiency (C2D). Analysis of his genomic DNA demonstrated that he carried one type I C2D allele associated with the HLA-A25, B18, DR15 haplotype ...

Tuning the Selectivity of the CO2 Reduction Reaction by Means of Synergistic Interactions in the Cu, Ag, Ce System

Advanced Functional Materials, EarlyView.
Multi‐metal Cu─Ce─Ag nanoparticles harness synergistic interactions to drive efficient electrochemical CO2 reduction reaction toward C2+ products at high current densities. Ag enhances CO production, Ce modulates Cu oxidation states, and together they boost *CO coverage and local pH to enhance C─C coupling, enabling record C2+ yields with suppressed ...

Relationship of Hematological Profiles with the Serum Complement System in Patients with Systemic Lupus Erythematosus

Biomedicines
Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder identified by hematological abnormalities including anemia, leukopenia, and thrombocytopenia. Complement system disturbance is implicated in the pathogenesis of SLE. In this work, we aim

Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications

Advanced Functional Materials, EarlyView.
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

Clinical and Genetic Spectrum of a Large Cohort With Total and Sub-total Complement Deficiencies

Frontiers in Immunology, 2019
The complement system is crucial for defense against pathogens and the removal of dying cells or immune complexes. Thus, clinical indications for possible complete complement deficiencies include, among others, recurrent mild or serious bacterial ...
