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

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 ...

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

Prenatal valproic acid-induced autism marmoset model exhibits higher salivary cortisol levels
Frontiers in Behavioral Neuroscience, 2022 Individuals with autism spectrum disorder (ASD) are exposed to a variety of stressors owing to their behavioral traits. Cortisol is a hormone typically associated with stress, and its concentration and response to stress are higher in individuals with ...

The Role of Reactive Oxygen Species (ROS) in the Formation of Extracellular Traps (ETs) in Humans
Biomolecules, 2015 Extracellular traps (ETs) are reticulate structures of extracellular DNA associated with antimicrobial molecules. Their formation by phagocytes (mainly by neutrophils: NETs) has been identified as an essential element of vertebrate innate immune defense.

Plasmolysis: Loss of Turgor and Beyond
Plants, 2014 Plasmolysis is a typical response of plant cells exposed to hyperosmotic stress. The loss of turgor causes the violent detachment of the living protoplast from the cell wall. The plasmolytic process is mainly driven by the vacuole.
