8-Aminoguanine and 8-aminoguanosine (via metabolism to 8-aminoguanine) are endogenous 8-aminopurines that induce diuresis, natriuresis and glucosuria by inhibiting purine nucleoside phosphorylase (PNPase); moreover, both 8-aminopurines cause antikaluresis by other mechanisms. Because 8-aminoinosine and 8-aminohypoxanthine are structurally similar to 8-aminoguanosine and 8-aminoguanine, respectively, we sought to define their renal excretory effects. First, we compared the ability of 8-aminoguanine, 8-aminohypoxanthine and 8-aminoinosine to inhibit recombinant PNPase. Read More

Oxidant-mediated modification and cross-linking of beta-2-microglobulin.

Free Radic Biol Med 2022 May 21. Epub 2022 May 21.

Department of Biomedical Sciences, Panum Institute, University of Copenhagen, Copenhagen, 2200, Denmark. Electronic address:

Beta-2-microglobulin (B2M) is synthesized by all nucleated cells and forms part of the major histocompatibility complex (MHC) class-1 present on cell surfaces, which presents peptide fragments to cytotoxic CD8 T-lymphocytes, or by association with CD1, antigenic lipids to natural killer T-cells. Knockout of B2M results in loss of these functions and severe combined immunodeficiency. Plasma levels of this protein are low in healthy serum, but are elevated up to 50-fold in some pathologies including chronic kidney disease and multiple myeloma, where it has both diagnostic and prognostic value.

Biomed Mater 2022 May 24. Epub 2022 May 24.

Department of Radiopharmacy and Medicinal Chemistry, Tehran University of Medical Sciences, 16 Azar Street, Tehran, 1439644545, Iran (the Islamic Republic of).

Multifunctional nanocarriers, specifically for tumor targeting and traceable features, have been increasingly considered in cancer therapies. Herein, a novel targeting agent (TA), tryptophan(TRP), was proposed for the synthesis of functionalized APTES-iron oxide nanoparticles using two methods, creating a smart drug delivery system (DDS). In one method, two-step, glutaraldehyde (GA) as a linker, bonded TRP and amino-functionalized magnetite (AMFM), and in the second method, one step, TRP binding was carried out by (3-dimethyl aminopropyl)-N'-ethyl carbodiimide hydrochloride (EDC)/ N-hydroxysuccinimide ester (NHS).

Improvement in Kidney Function After Discontinuation of Fenofibrate in Outpatient Nephrology Consultation for Chronic Kidney Disease.

Kidney Blood Press Res 2022 May 24. Epub 2022 May 24.

Background: It has been noted in observational and interventional studies that individuals exposed to fenofibrate can exhibit a rise in serum creatinine (sCr) concentration. However, it is not known to what extent this phenomenon impacts kidney function in patients who are referred to a nephrology clinic for consultation for chronic kidney disease (CKD).

Emerging strategies for treating gout.

Curr Opin Pharmacol 2022 May 19;65:102241. Epub 2022 May 19.

Division of Clinical Immunology and Rheumatology, University of Alabama Birmingham (UAB) and Birmingham VA Medical Center, Birmingham, AL, USA. Electronic address:

Gout is a common and potentially debilitating disease characterized by a painful inflammatory arthritis ("gout flare"), caused by the deposition of monosodium urate crystals in joints and surrounding tissues. Gout is frequently comorbid with other chronic conditions such as chronic kidney disease (CKD) and diabetes mellitus, which can make treatment complex, as traditional mainstays (such as allopurinol, colchicine, and corticosteroids) may not be preferred or could have adverse events in such patients. Understanding the pathophysiology of hyperuricemia, gout, and crystalline-driven inflammation is key for drug development and research. Read More

Chemokines, Soluble PD-L1, and Immune Cell Hyporesponsiveness are Distinct Features of SARS-CoV-2 Critical Illness.

Am J Physiol Lung Cell Mol Physiol 2022 May 24. Epub 2022 May 24.

Benaroya Research Institute, Seattle, WA, United States.

Critically ill patients manifest many of the same immune features seen in COVID-19, including both "cytokine storm" and "immune suppression." However, direct comparisons of molecular and cellular profiles between contemporaneously enrolled critically ill patients with and without SARS-CoV-2 are limited. We sought to identify immune signatures specifically enriched in critically ill patients with COVID-19 compared to patients without COVID-19. Read More
