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 ...

Ultrastructure of Lipoma [PDF]
Cancer, 1982 Eleven benign lipogenic tumors comprising ten ordinary lipomas and one fibroblastic lipoma were studied by light and electron microscopy. The former, which contained only a few inconspicuous septa, were composed of univacuolar mature adipocytes. No young forms of adipocytic differentiation were seen reflecting the slow growth of the ordinary lipomas ...

Ultrastructure of the esthesioneuroblastoma [PDF]
Cancer, 1976 A tumor in the anatomic location and with the light microscopic appearance of an esthesioneuroblastoma was examined with the electron microscope. Secretory-type granules, cytoplasmic fibrils, and microtubules similar to those described in neuroblastomas were found in many of the tumor cells, which supports an origin from the sympathetic autonomic ...

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.

Ultrastructural Immunochemistry [PDF]
Cold Spring Harbor Protocols, 2008 INTRODUCTIONThe use of colloidal gold technology was undoubtedly the most significant event in the development of immunochemistry. Gold particles are particularly useful for transmission electron microscopy (TEM) studies, because they scatter electrons strongly and even small particles are clearly visible under the electron microscope.

Follicular complex may predict reproductive tactics in siluriform fishes
Heliyon, 2023 In this study, we evaluated the morphology and morphometry of the layers that make up the follicular complex surrounding mature oocytes in the six fish species Auchenipterichthys longimanus, Ageneiosus ucayalensis, Hypophthalmus marginatus, Baryancistrus

Changes of mitochondrial ultrastructure and function during ageing in mice and Drosophila
eLife, 2017 Ageing is a progressive decline of intrinsic physiological functions. We examined the impact of ageing on the ultrastructure and function of mitochondria in mouse and fruit flies (Drosophila melanogaster) by electron cryo-tomography and respirometry.

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.
