Elevated Urinary 3-OH-BaP Levels and CYP1A1 Enzyme Activity in Pediatric Acute Lymphoblastic Leukemia: A Case-Control Study in a High-Pollution Region

Loly Rotua Dharmanita Siagian, Kusworini Handono, Hidayat Sujuti, Arinto Yudi Ponco Wardoyo

Introduction: pollutants related to acute lymphoblastic leukemia (ALL) include polycyclic aromatic hydrocarbons (PAHs), such as the carcinogenic benzo[a]pyrene (BaP). Urinary 3-hydroxybenzo[a]pyrene (3-OH-BaP) is a key biomarker for BaP exposure. Benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide (BPDE-dG), the ultimate metabolite of BaP, correlates with CYP1A1 activity. However, the …

Enhancing logistic regression performance for identifying preservatives in coconut sap using electronic nose

Yahya Efendi, Arinto Yudi Ponco Wardoyo

Indonesian coconut sugar has experienced rapid export growth in recent years. However, its primary raw material—coconut sap—is highly susceptible to spontaneous fermentation caused by microbial activity, which degrades its quality. To prevent this, farmers often add natural preservatives such as jackfruit wood …

Analysis of Urinary Midkine and Volatile Organic Compound (VOC) Levels Using a Breath Analyzer for Screening and Early Diagnosis of Lung Cancer

Saidah Mafisah, Ungky Agus Setyawan, Rezki Tantular, Deden Permana et autres

Introduction: Lung cancer is the leading cause of cancer-related mortality worldwide. Midkine, a heparin-binding growth factor, promotes proliferation, angiogenesis, and metastasis.
