In Vivo UV-Induced Fluorescence Spectroscopy of Skin in Parkinson's Disease.
Dokl Biol Sci
January 2025
Research Center of Neurology, Moscow, Russia.
Characteristic patterns of UV-induced skin autofluorescence were determined for patients with Parkinson's disease (PD) and associated with dysmetabolic alterations, such as nonenzymatic protein glycation, an increase in extracellular matrix stiffness, impaired metabolism of tissue fluorophores, mitochondrial dysfunction, and accumulation of aberrant proteins. Key differences in skin autofluorescence spectra were for the first time observed in PD, making it possible to discriminate between PD patients and healthy persons or individuals without signs of chronic neurodegeneration. Namely, skin fluorescence related to the reflected signal upon excitation with UV light at 375 nm was lower in PD patients.

Background: Hippuric acid (HA), a host-microbe co-metabolite, normally derives from gut microbial catabolism of dietary polyphenols.
Objectives: We investigated the potential interplay between dietary polyphenols and gut microbiota on circulating HA levels, and examined the associations between serum concentrations of HA and cardiometabolic risk markers.
Methods: In a 1-year cohort of 754 community-dwelling adults, serum HA and its precursor [benzoic acid (BA)] and fecal microbiota were assayed using liquid chromatography-tandem mass spectrometry and 16S ribosomal RNA sequencing, respectively.

Key principles of rheumatoid arthritis (RA) management include early patient evaluation by a rheumatologist and early initiation of pharmacologic therapy in patients at risk for chronic disease. Early diagnosis and appropriate management are essential to prevent joint damage. Patients with RA usually report pain and swelling in multiple joints and prolonged stiffness in the morning that improves with activity.

Department of Biochemistry, Velammal Medical College Hospital and Research Institute, Madurai, Tamil Nadu 632002 India.
Unlabelled: Non-alcoholic fatty liver disease (NAFLD) is one of the major causes of chronic liver disease worldwide. There are conflicting reports on the association of serum ferritin levels and its utility in discriminating various stages of liver fibrosis in patients with NAFLD. This study is done to address the conflicts by analysing the National Health and Nutritional Examination Survey 2017-2020 (NHANES 2017-2020) data.

Introduction: Ankylosing spondylitis (AS), a chronic inflammatory spondyloarthropathy affecting the spine, progressively leads to increased spinal stiffness. This condition increases the risk of spine fractures in patients, even from trivial injuries. The process of slow bone formation within the ligaments of the spine and the fusion of the spinal diarthrosis contribute to the most prominent symptom of progressive stiffness of joints, predominantly affecting the spine and sacroiliac joints.
