The utility of urinary tests for the monitoring of the treatment efficacy and adverse events of anticancer therapies is constrained by the low concentration of relevant urinary biomarkers. Here we report, using mice with lung cancer and treated with chemotherapy, of a urinary fluorescence test for the concurrent monitoring of the levels of a tumour biomarker (cathepsin B) and of a biomarker of chemotherapy-induced kidney injury (N-acetyl-β-D-glucosaminidase). The test involves two intratracheally administered urinary reporters leveraging caged bioorthogonal click handles for the biomarker-dependent activation of 'clickability' and renal clearance, and the bioorthogonal click reaction of each renally cleared reporter with paired fluorescence indicators in the collected urine.

Approximately 64% of the Republic of Korea comprises mountainous areas, which as cold and high-altitude regions are gravely affected by climate change. Within the mountainous and the alpine-subalpine ecosystems, microbial communities play a pivotal role in biogeochemical cycling and partly regulate climate change through such cycles. We investigated the composition and function of microbial communities, with a focus on fungal communities, in Republic of Korea's second tallest mountain, Mt.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a prevalent complication with poor outcomes, and its early prediction remains a challenging task. Currently available biomarkers for acute kidney injury (AKI) include serum cystatin C (sCysC) and urinary N-acetyl-β-D-glucosaminidase (uNAG). Widely used biomarkers for assessing cardiac function and injury are N-terminal pro B-type natriuretic peptide (NT-proBNP) and cardiac troponin I (cTnI).

Objectives: To study the significance of serum 25-hydroxyvitamin D [25-(OH)D] level in the clinicopathological characteristics and prognosis of children with immunoglobulin A vasculitis nephritis (IgAVN).
Methods: A retrospective analysis was conducted on the clinical data of children with IgAVN who underwent renal biopsy at Suzhou Hospital Affiliated to Anhui Medical University and Jinling Hospital of the Medical School of Nanjing University from June 2015 to June 2020. Based on serum 25-(OH)D level, the patients were divided into a normal group and a lower group.
