Published: July 1991

Albumin is one of the major products of hepatic protein synthesis. Although it is a small molecule, it is an important diagnostic and prognostic determinant, as well as a useful therapeutic agent. A review of the evolution and structure of albumin as well as a description of its colloidal and buffering properties is presented. Synthesis, distribution, and catabolism, the major determinants of serum albumin level, are discussed. Emphasis is given to those mechanisms responsible for the regulation of these processes, including the importance of nutritional status on substrate availability, energy supply, and hormonal modulation.

Association of systemic inflammatory markers with white matter hyperintensities and microstructural injury: an analysis of UK Biobank data.

J Psychiatry Neurosci

January 2025

Li, Tian, Yang, Cao, Su); the School of Electrical and Information Engineering, Zhengzhou University of Light Industry, Zhengzhou, China (Zhu); the Department of Medical Imaging, Henan Provincial People's Hospital & Zhengzhou University People's Hospital, Zhengzhou, China (P. Li).

Background: White matter damage is closely associated with cognitive and psychiatric symptoms and is prevalent in cerebral small vessel disease (CSVD); although the pathophysiological mechanisms involved in CSVD remain elusive, inflammation plays a crucial role. We sought to investigate the relationship between systemic inflammation markers and imaging markers of CVSD, namely white matter hyperintensity (WMH) and microstructural injury.

Methods: We conducted a study involving both cross-sectional and longitudinal data from the UK Biobank Cohort.

Background: Systemic inflammation plays a crucial role in the development and progression of chronic heart failure (CHF) across all phenotypes. The continuous release of pro-inflammatory cytokines causes muscle atrophy and adipocyte breakdown, ultimately resulting in cachexia. Long non-coding RNAs (lncRNAs) are emerging as potential biomarkers associated with cachexia, as they indirectly regulate muscle and fat tissue metabolism.

Associations between brominated flame retardants exposure and non-alcoholic fatty liver disease: Mediation analysis in the NHANES.

Background: Exposure to brominated flame retardants (BFRs) may negatively impact human health. The association of BFRs with nonalcoholic fatty liver disease (NAFLD) in the general population is unclear. Meanwhile, limited studies have investigated the potential role of oxidative stress and inflammation in this link.

A comprehensive strategy, including spectroscopic, molecular simulation, proteomics, and bioinformatics techniques, was employed to investigate a novel triazole, 5-(4-methoxyphenyl)-1-phenyl-1H-1,2,3-triazole, its interactions with high-abundance blood proteins, and identification of low-abundance proteins. The binding constants and thermodynamic parameters of the triazole to two high-abundance blood globular proteins, human serum albumin, and human immunoglobulin G (HIgG), were obtained by spectroscopic techniques and computational chemistry. The two-dimensional gel electrophoresis in combination with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was employed to isolate and identify differentially expressed low-abundance proteins in human blood serum samples following exposure to the triazole.

CRP is a biomarker of acute inflammation linked to metabolic complications. Given the rising prevalence of these conditions in India, we investigated the genetic basis of CRP levels in Indian adolescents, an underrepresented group in genetic studies, to identify early markers of metabolic risk. We performed a two-phased genome-wide association study (GWAS; N = 5052) and an independent Exome-wide association study (ExWAS; N = 4547), to identify both common and rare genetic variants associated with CRP levels.
