Structure‐Tailoring Cerium Nanozymes with Self‐Cascade ROS Scavenging Catalysis Modulate the Microbiota‐Gut‐Joint Axis for Rheumatoid Arthritis Therapy

Advanced Science, EarlyView.
A valence‐engineered CeOX nanozyme, with its Ce3+/Ce4+ ratio precisely controlled within the range of 0.27 to 0.93 through Au deposition, performs a self‐cascade oxidase‐superoxide dismutase‐peroxidase reaction, enabling continuous reactive oxygen species scavenging while minimizing oxygen generation.

Three Hypoxanthine Derivatives from the Marine Cyanobacterium Okeania hirsuta

Molbank
Three novel hypoxanthine derivatives (1–3) were obtained from the Okinawan cyanobacterium Okeania hirsuta. The structures of these compounds were elucidated mainly based on the spectroscopic data, including 1D and 2D NMR, as well as high-resolution mass ...

Uptake of purines in Plasmodium falciparum-infected human erythrocytes is mostly mediated by the human Equilibrative Nucleoside Transporter and the human Facilitative Nucleobase Transporter [PDF]

, 2010
<b>Background</b>: Plasmodium parasites are unable to synthesize purines de novo and have to salvage them from the host. Due to this limitation in the parasite, purine transporters have been an area of focus in the search for anti-malarial ...

Comprehensive Measurement of Inter‐Individual Variation in DNA Repair Capacity in Healthy Individuals

Advanced Science, EarlyView.
Susceptibility to the health effects of DNA damage depends on a person's ability to repair DNA damage, but DNA repair has been difficult to measure in populations. A functional assay called FM‐HCR is used to measure DNA repair in 6 major pathways across 56 individuals.

Establishment and optimization of a novel mouse model of hyperuricemic nephropathy

Renal Failure
Hyperuricemia is a metabolic disorder characterized by elevated serum uric acid levels. Soluble urate can activate immune responses, and the excessive accumulation of urate in the kidneys results in hyperuricemic nephropathy (HN). However, the lack of an

The Metabolomic Profile of Lymphoma Subtypes: A Pilot Study

Molecules, 2019
Lymphoma defines a group of different diseases. This study examined pre-treatment plasma samples from 66 adult patients (aged 20−74) newly diagnosed with any lymphoma subtype, and 96 frequency matched population controls. We used gas chromatography-

Metabolomic profiling of macrophages determines the discrete metabolomic signature and metabolomic interactome triggered by polarising immune stimuli [PDF]

, 2018
Priming and activating immune stimuli have profound effects on macrophages, however, studies generally evaluate stimuli in isolation rather than in combination.

Identification Epitope on VP4 Protein of Senecavirus A Recognized by a Monoclonal Antibody

Animal Research and One Health, EarlyView.
This study aims to identify conserved antigenic epitopes on the SVA VP4 protein using monoclonal antibodies, providing valuable tools for further exploring its functions and developing detection methods. SVA VP4 protein was expressed in Escherichia coli and purified with High‐Affinity Ni‐Charged Resin FF.
