TMAO reductase, a biomarker for gut permeability defect induced inflammation, in mouse model of chronic kidney disease and dextran sulfate solution-induced mucositis.

Asian Pac J Allergy Immunol 2021 Jul 21. Epub 2021 Jul 21.

Department of Microbiology, King Chulalongkorn Memorial Hospital, Thai Red Cross Society, Bangkok, Thailand.

Background: The excretion of trimethylamine N-oxide (TMAO) (uremic toxin) into the intestine might be enhanced, due to the limited renal elimination in chronic kidney disease (CKD), possibly induced TMAO reductase (a TMAO-neutralizing enzyme) in gut bacteria. Detection of TMAO reductase in serum could be used as a biomarker of gut permeability defect.

Functionally Essential Tubular Proteins Are Lost to Urine-Excreted, Large Extracellular Vesicles during Chronic Renal Insufficiency.

Kidney360 2020 Oct 29;1(10):1105-1115. Epub 2020 Oct 29.

Department of Physiology, Medical College of Wisconsin, Milwaukee, Wisconsin.

Background: The 5/6 nephrectomy (5/6Nx) rat model recapitulates many elements of human CKD. Within weeks of surgery, 5/6Nx rats spontaneously exhibit proximal tubular damage, including the production of very large extracellular vesicles and brush border shedding. We hypothesized that production and elimination of these structures, termed large renal tubular extracellular vesicles (LRT-EVs), into the urine represents a pathologic mechanism by which essential tubule proteins are lost.

Brazilian registry for the elimination of hepatitis C in dialysis units: a call to action for Nephrology.

J Bras Nefrol 2021 Jul 7. Epub 2021 Jul 7.

Sociedade Brasileira de Nefrologia, São Paulo, SP, Brasil.

Infection by the hepatitis C virus is more prevalent in patients on dialysis than in the general population in Brazil, and has been associated with worse outcomes. Current therapy for hepatitis C is highly effective, safe, and widely available in Brazil, with coverage provided to dialysis patients with chronic kidney disease, which makes the elimination of hepatitis C a viable target. The Brazilian Society of Nephrology, the Brazilian Society of Hepatology, and the Brazilian Liver Institute developed the "Brazilian Registry for the Elimination of Hepatitis C in Dialysis Units".

Preclinical development and characterisation of Tc-NM-01 for SPECT/CT imaging of human PD-L1.

Am J Nucl Med Mol Imaging 2021 15;11(3):154-166. Epub 2021 Jun 15.

Department of Nuclear Medicine, University Hospital RWTH Aachen Germany.

The level of expression of programmed cell death-1 (PD-1)/programmed death ligand-1 (PD-L1) is a predictive biomarker for cancer immunotherapy, however, its detection remains challenging due to tumour heterogeneity and the influence from the binding of therapeutic agents. We recently developed [Tc]-NM-01 as a companion diagnostic imaging agent for non-invasive molecular imaging of PD-L1 by single-photon emission computed tomography (SPECT). The aim of the study was to evaluate the [Tc] radiolabelling of GMP graded NM-01 and its pharmacology, pharmacokinetics and toxicology. Read More

Mixing Matrix-corrected Whole-body Pharmacokinetic Modeling Using Longitudinal Micro-computed Tomography and Fluorescence-mediated Tomography.

Mol Imaging Biol 2021 Jul 6. Epub 2021 Jul 6.

Institute for Experimental Molecular Imaging, Helmholtz-Institute for Biomedical Engineering, RWTH Aachen University Clinic, 52074, Aachen, Germany.

Purpose: Pharmacokinetic modeling can be applied to quantify the kinetics of fluorescently labeled compounds using longitudinal micro-computed tomography and fluorescence-mediated tomography (μCT-FMT). However, fluorescence blurring from neighboring organs or tissues and the vasculature within tissues impede the accuracy in the estimation of kinetic parameters. Contributions of elimination and retention activities of fluorescent probes inside the kidneys and liver can be hard to distinguish by a kinetic model. Read More

The biological effects of radiation-induced liver damage and its natural protective medicine.

Prog Biophys Mol Biol 2021 Jul 1. Epub 2021 Jul 1.

Beijing Key Laboratory for Separation and Analysis in Biomedicine and Pharmaceuticals, School of Life Science, Beijing Institute of Technology, Beijing, 100081, China.

The biological damage caused by the environmental factors such as radiation and its control methods are one of the frontiers of life science research that has received widespread attention. Ionizing radiation can directly interact with target molecules (such as DNA, proteins and lipids) or decomposed by radiation from water, leading to changes in oxidative events and biological activities in cells. Liver is a radiation-sensitive organ, and its radiosensitivity is second only to bone marrow, lymph, gastrointestinal tissue, gonads, embryos and kidneys. Read More

Serum Liberation of Fetal Fibronectin Variants in Patients with Pulmonary Hypertension: ED-A Fn as Promising Novel Biomarker of Pulmonary Vascular and Right Ventricular Myocardial Remodeling.

J Clin Med 2021 Jun 9;10(12). Epub 2021 Jun 9.

Department of Internal Medicine I, Jena University Hospital, 07740 Jena, Germany.

Management and Treatment of Hepatitis C: Are There Still Unsolved Problems and Unique Populations?

Viruses 2021 Jun 1;13(6). Epub 2021 Jun 1.

Department of Biomedical Sciences, Humanitas University, Pieve Emanuele, 20082 Milan, Italy.

Direct-acting antivirals (DAA) have revolutionized the treatment of patients with chronic hepatitis C virus (HCV) infection, possibly leading to HCV elimination by 2030 as endorsed by the World Health Organization (WHO). However, some patients belonging to the so-called unique or special populations are referred to as difficult-to-treat due to unreached sustained virological response, potential drug side effects or interactions or co-morbidities. Several years after the DAA introduction and on the basis of excellent findings in terms of efficacy and safety, some doubts arise around the exact meaning of the special population designation and whether this group of patients actually exists.

Front Vet Sci 2021 11;8:679657. Epub 2021 Jun 11.

Yangtze River Fisheries Research Institute, Chinese Academy of Fishery Sciences, Wuhan, China.

The aim of this study was to investigate the effect of different water temperatures (19, 25, and 30°C) on tissue residue depletion of tiamulin in Nile tilapia () after five consecutive days of oral administration at the dose of 20 mg/kg body weight and to calculate the corresponding elimination half-life ( ) and withdrawal times (WTs). After oral administration at scheduled 11 time points (1, 2, 3, 5, 7, 9, 12, 15, 20, 25, and 30 days), samples of plasma and tissues (muscle plus skin, liver, kidney, and gill) were collected. Tiamulin concentration in samples were determined by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Read More

Serum markers of fibrosis, cardiovascular and all-cause mortality in hemodialysis patients: the AURORA trial.

Clin Res Cardiol 2021 Jun 25. Epub 2021 Jun 25.

Université de Lorraine, Inserm, Centre d'Investigations Cliniques-1433, and Inserm U1116, CHRU Nancy; F-CRIN INI-CRCT, Nancy, France.

Background: Biomarkers of fibrosis are associated with outcome in several cardiovascular diseases. However, their relevance to chronic kidney disease and dialysis is uncertain, as it remains unclear how the kidneys and the dialysis procedure itself affect their elimination and degradation. We aimed to investigate the relationship of the blood levels of two markers associated with fibrosis: procollagen type I C-terminal pro-peptide (PICP) and galectin-3 (Gal-3) with mortality in dialysis patients.

Is elimination of HCV realistic by 2030: France.

Liver Int 2021 06;41 Suppl 1:45-49

Université Paris Centre, Département d'Hépatologie, Hôpital Cochin, APHP; INSERM U1223, Institut Pasteur, Paris, France.

The World Health Organization (WHO) has proposed a plan for the elimination of viral hepatitis with a goal of reducing new hepatitis infections by 30% and 90% in 2020 and 2030, and associated mortality by 10% and 65% respectively. Actions and targets to reach these goals include improving hepatitis B virus (HBV) vaccination programs, the prevention of mother-to-child transmission of HBV, improving the safety of blood products and injections, risk reduction policies and optimizing the diagnosis and treatment of hepatitis. The goal of eliminating hepatitis C virus (HCV) by 2030 is based on three main actions: increased screening, strengthening access to care and the prevention of infections and re-infections.
