Article Abstract
We recently proposed an equation to estimate the glomerular filtration rate (GFR) in children with cancer based on plasma cystatin C and serum creatinine levels together with body weight (the "CysPed equation"). The current clinical study reports a prospective evaluation of this equation in 18 children treated by nephrotoxic chemotherapy. The CysPed equation resulted in less bias and greater precision compared to two equations previously proposed equations by Schwartz, with or without plasma cystatin C. Moreover, the decrease in GFR due to chemotherapy was clearly identified by the CysPed equation. This equation may be used to monitor the renal function in childhood cancer units.

Plasma endostatin and its association with new-onset acute kidney injury in critical care.
J Intensive Care
September 2025
Department of Clinical Sciences, Anaesthesiology and Intensive Care, Lund University, SE-22185, Lund, Sweden.
Background: Endostatin is a promising biomarker for predicting acute kidney injury (AKI) and mortality in the intensive care unit (ICU). We investigated plasma endostatin levels at ICU admission as predictors of new-onset AKI within 48 h after ICU admission, renal replacement therapy (RRT) within 7 days after ICU admission, and 30-day mortality.
Methods: A retrospective multicentre study was performed with admissions to four ICUs.
Diurnal rhythm of the human plasma proteome.
Clin Proteomics
August 2025
Department of Clinical Biochemistry, Copenhagen University Hospital - Bispebjerg, Nielsine Nielsens Vej 4B, Copenhagen, Denmark.
Background: Plasma is the most used clinical specimen, yet diurnal variation in plasma proteins remains largely unexplored. We aimed to identify diurnally-regulated proteins in healthy individuals and assess their potential diagnostic implications, and highlight how diurnal awareness can advance future biomarker research.
Methods: Twenty-four healthy young individuals were studied under highly controlled conditions.
Metabolic Syndrome and Insulin Resistance Are Associated With Normal-Range Aspartate Aminotransferase, Alanine Aminotransferase, and Their Ratio in Chinese Women With Polycystic Ovary Syndrome.

First Affiliated Hospital, Heilongjiang University of Chinese Medicine, Harbin, China.
Aim: To determine whether metabolic syndrome (MS), insulin resistance (IR), myocardial enzymes, and kidney function are related to the normal-range of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and their ratio in Chinese women with polycystic ovary syndrome (PCOS).
Methods: The research, a secondary analysis of the Acupuncture and Clomiphene for Chinese Women with PCOS trial (PCOSAct), enrolled 922 participants with less than 40 U/L of AST and ALT. Linear regression and trend analyses were used to analyze the relationship between AST, ALT, AST/ALT ratio and anthropometric and metabolic characteristics.
Functional, Structural and Genetic Modulation in Plasma and Renal Antioxidant Systems by Quercetin, Catechin and Genistein in Cisplatin-Induced Acute Nephrotoxicity in Wistar Rats.

The study aimed at gaining mechanistic insights into the modulation of cisplatin-induced (cDDP, 12 mg/kg-IP) renal toxicity by quercetin, catechin, and genistein in Wistar rats. Blood was analyzed for alterations in acute renal biomarkers (KIM-1, Cystatin-C, GGT, BUN, CR, UA) together with the changes in the activities of antioxidant biomarkers (TAS, TTH, GSH) and cellular damage indicators (MDA, AOPP and 8-OHdG). Additionally, alterations in the activities, variations in genetic expression of antioxidant enzymes (CAT, SOD, GPx, GST, AE, GR) and histomorphological lesions in the kidneys were studied.

The emergence of drug-resistant Gram-positive pathogens, particularlyand, has driven the need for novel antimicrobial agents. This study explores 21 newly synthesized peptidomimetic analogues of cystatin C -terminal fragment, designed to enhance bioactivity, solubility, and safety. These compounds were evaluated for antimicrobial potency, cytotoxicity, pro-proliferative effects, and pharmacokinetic properties.
