Effects of Maternal Undernutrition on Glomerular Ultrastructure in Rat Offspring

open access: yesPediatrics 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

open access: yesToxics, 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 ...

Ultrastructure of calcareous dinophytes (Thoracosphaeraceae, Peridiniales) with a focus on vacuolar crystal-like particles. [PDF]

open access: yes, 2013
Biomineralization in calcareous dinophytes (Thoracosphaeracaea, Peridiniales) takes place in coccoid cells and is presently poorly understood. Vacuolar crystal-like particles as well as collection sites within the prospective calcareous shell may play a ...

Aliskiren Reduces the Adrenal Zona Glomerulosa Apoptosis and Autophagy in Wistar Rats with 2K1C Hypertension

open access: yesInternational Journal of Hypertension, 2020
Hypertension is a disease classified as primary or secondary, manifested not only by elevation of blood pressure but also involved in structural and functional changes of target organs. Renal artery stenosis is a leading factor of secondary hypertension,

Subfamily hypostominae: similarities and differences in testicular structure of amazonian fish

open access: yesBMC Zoology, 2022
Background Hypostominae is a subfamily of the family Loricariidae that has a great diversity of species. Accordingly, testicular studies in fish can contribute to the phylogeny and taxonomy of species and to the comparison of reproductive aspects between
