Effects of Maternal Undernutrition on Glomerular Ultrastructure in Rat Offspring
Pediatrics and Neonatology, 2009 Intrauterine growth restriction (IUGR) can reduce glomerular number and increase blood pressure in rats. The aim of this study was to assess the effects of maternal undernutrition during late gestation on glomerular ultrastructure in adult rat offspring.

Uptake of Radionuclides by Bryophytes in the Chornobyl Exclusion Zone
Toxics, 2023 The “Chernobyl nuclear disaster” released huge amounts of radionuclides, which are still detectable in plants and sediments today. Bryophytes (mosses) are primitive land plants lacking roots and protective cuticles and therefore readily accumulate ...
