  • Induction of chromosomal damage in exfoliated buccal and nasal cells of road markers. [Journal Article]
    J Toxicol Environ Health A 2019; 82(17):969-976Wultsch G, Nersesyan A, … Knasmüller S
  • Road markers are exposed to various chemicals and particles. The aim of this study was to determine whether road worker exposure induceschromosomal damage which is indicative for increased cancer risks. Micronucleus (MN) cytome assays were thus conducted with exfoliated nasal and buccal cells collected from 42 workers and 42 matched controls. The frequencies of MN (reflecting chromosomal aberrati…
  • Segmental villous mineralization: A placental feature of fetal vascular malperfusion. [Journal Article]
    Placenta 2019; 86:20-27Stanek J
  • CONCLUSIONS: FVM is characterized by temporal heterogeneity, i.e. coexistence of lesions of various duration, and strongly and independently correlates with clusters of mineralized chorionic villi. Therefore, segmental villous mineralization should be included into the category of segmental FVM. It can be seen even in totally fibrotic placentas of prolonged stillbirth when other histological features of segmental vascular malperfusion can be obscured by global villous sclerosis.
  • Effects of age, sex, medication, and environmental conditions on genetic alterations in oral mucosa cells. [Journal Article]
    Heliyon 2019; 5(6):e01840Cavalcante DNC, Crispim BDA, … Barufatti A
  • In the present study, we evaluated the effects of biological factors, lifestyle factors, and environmental conditions on the induction of DNA damage in exfoliated cells of the oral mucosa. Age, sex, medication use, and environmental conditions were analyzed in individuals residing in the cities of Caarapó and Itaporã. The individuals were assessed by a questionnaire, and oral mucosa cells were co…
  • A prognostic nomogram for neuroblastoma in children. [Journal Article]
    PeerJ 2019; 7:e7316Li X, Meng Y
  • CONCLUSIONS: The nomogram showed stronger predictive power than the INSS staging system, tumor histology and COG risk group. Precise estimates of the prognosis of childhood neuroblastoma might help doctors make better treatment decisions.
  • Characterization of irreversible electroporation on the stomach: A feasibility study in rats. [Journal Article]
    Sci Rep 2019; 9(1):9094Lee JM, Choi HS, … Kim HB
  • Irreversible electroporation (IRE) is a newly developed non-thermal ablative therapy. During the IRE procedure, the permeability of the cell membrane is irreversibly changed by application of high-energy pulses across the tissue. This induces the breakdown of cell homeostasis, and thereby cell death. Here, we present an in vivo study to demonstrate IRE ablation of gastric tissue and characterize …
