Inflammation, DNA-centered radicals, and oxidative genotoxicity: The role of HOCl produced by myeloperoxidase in carcinogenesis [PDF]

open access: yes, 2009
Myeloid cells (macrophages and neutrophils) infiltrate and synthesize myeloperoxidase (MPO) in sites of inflammation, producing gentotoxicity. In RAW 264.7 macrophages, bacterial lipopolysaccharide (LPS) induces superoxide radical anion, nuclear ...

Absolute quantification of the host-to-parasite DNA ratio in Theileria parva-infected lymphocyte cell lines [PDF]

open access: yes, 2016
Theileria parva is a tick-transmitted intracellular apicomplexan pathogen of cattle in sub-Saharan Africa that causes East Coast fever (ECF). ECF is an acute fatal disease that kills over one million cattle annually, imposing a tremendous burden on ...

Application of Liquid Chromatography Coupled to Mass Spectrometry for Direct Estimation of the Total Levels of Adenosine and Its Catabolites in Human Blood

open access: yesPharmaceuticals
Adenosine is a multifunctional nucleoside with several roles across various levels in organisms. Beyond its intracellular involvement in cellular metabolism, extracellular adenosine potently influences both physiological and pathological processes.

Non-targeted Metabolomics Analysis of the Effects of Arabinogalactan on the Metabolites of Akkermansia muciniphila

open access: yesShipin gongye ke-ji, 2022
Among many plant polysaccharides, arabinogalactan had the best growth-promoting effect on Akkermansia muciniphila (Akk) model strain (DSM 22959). In order to further explore the influence of arabinogalactan on Akk metabolites, arabinogalactan was used as

Glutaredoxin GRXS17 associates with the cytosolic iron-sulfur cluster assembly pathway [PDF]

open access: yes, 2016
Cytosolic monothiol glutaredoxins (GRXs) are required in iron-sulfur (Fe-S) cluster delivery and iron sensing in yeast and mammals. In plants, it is unclear whether they have similar functions.

FLAVIN-HYPOXANTHINE DINUCLEOTIDE

open access: yesTHE JOURNAL OF VITAMINOLOGY, 1957
1. FHD was synthesized from FAD by deamination with nitrous acid and the product was first isolated as barium salt. The yield and purity were, however, unsatisfactory by this method. Therefore, the product was extracted with cresol, followed by transfer in aqueous phase, and by subjecting to column chromatography, FHD was obtained in high purity in ...

Response to Allopurinol and Febuxostat According to the Fractional Excretion of Urate in Men With Gout

open access: yesArthritis Care &Research, EarlyView.
Objective Body mass index (BMI), glomerular filtration rate (GFR), and pretreatment urate levels have been reported to influence the urate‐lowering response to allopurinol. We investigated whether the fractional excretion of uric acid (FEUA) also modulates this response and relates to oxypurinol concentrations.

Metabolomics guides rational development of a simplified cell culture medium for drug screening against Trypanosoma brucei [PDF]

open access: yes, 2013
n vitro culture methods underpin many experimental approaches to biology and drug discovery. The modification of established cell culture methods to make them more biologically relevant or to optimize growth is traditionally a laborious task.

A New 3D Colon on a Chip to Decipher the Influence of Mechanical Forces on the Physiological Cellular Ecosystem

open access: yesAdvanced Healthcare Materials, EarlyView.
To dissect how mechanical forces influence intestinal physiology, we developed a stretchable 3D colon‐on‐chip that integrates tunable topography, stiffness and peristalsis‐like motion within a physiologically relevant microenvironment. We showed that stretching is a dominant factor governing epithelial behavior, markedly enhancing proliferation and ...
