Elevated levels of C3, C4, and CH50 of the complement system in ICU and non‐ICU patients with COVID‐19

open access: yesHealth Science Reports, 2022
Purpose SARS‐CoV‐2 infection has spread in each corner of the world. Many health systems have dealt with it intensively. The complement system is an instrumental component in the inflammatory immune response and plays a role in the activation of blood ...

Altered Complement System Activity in Schizophrenia: Overexpression of C4 and/or Abnormal Expression of Complement Control Proteins in the DLPFC, Parietal Cortex, Temporal Cortex, Associative Striatum, Hippocampus, Cerebellum and Whole Blood

open access: yesEuropean Psychiatry, 2022
Introduction In schizophrenia, abnormal synaptic pruning during adolescence may be due to an altered Complement system activity. While this hypothesis is supported by C4 overexpression in various brain regions of individuals with schizophrenia, such ...

Varieties of De Morgan monoids: covers of atoms [PDF]

open access: yesThe Review of Symbolic Logic 13 (2020) 338-374, 2018
The variety DMM of De Morgan monoids has just four minimal subvarieties. The join-irreducible covers of these atoms in the subvariety lattice of DMM are investigated. One of the two atoms consisting of idempotent algebras has no such cover; the other has just one. The remaining two atoms lack nontrivial idempotent members.

Structural Model for Factor X Inhibition of IgM and Complement-Mediated Neutralization of Adenovirus

open access: yesViruses, 2023
Adenovirus has strong therapeutic potential as an oncolytic virus and gene therapy vector. However, injecting human species C serotype 5 adenovirus, HAdv-C5, into the bloodstream leads to numerous interactions with plasma proteins that affect viral ...

Unified representation of the C3, C4, and CAM photosynthetic pathways with the Photo3 model [PDF]

open access: yesEcological Modelling, 384, 173-187 (2018), 2018
Recently, interest in crassulacean acid metabolism (CAM) photosynthesis has risen and new, physiologically based CAM models have emerged. These models show promise, yet unlike the more widely used physiological models of C3 and C4 photosynthesis, their complexity has thus far inhibited their adoption in the general community.

Clinical Characteristics of Patients With IgG4-Related Disease Complicated by Hypocomplementemia

open access: yesFrontiers in Immunology, 2022
BackgroundA proportion of patients with immunogloblin G (IgG) 4-related disease (IgG4-RD) have hypocomplementemia. We aimed to identify characteristics of such patients.MethodsWe analyzed the demographic and clinical data and complement levels of 85 ...

The C4 Clustering Algorithm: Clusters of Galaxies in the Sloan Digital Sky Survey [PDF]

open access: yesAstron.J.130:968,2005, 2005
We present the "C4 Cluster Catalog", a new sample of 748 clusters of galaxies identified in the spectroscopic sample of the Second Data Release (DR2) of the Sloan Digital Sky Survey (SDSS). The C4 cluster--finding algorithm identifies clusters as overdensities in a seven-dimensional position and color space, thus minimizing projection effects which ...
