Ultrastructure of elastofibroma [PDF]
Cancer, 1977 An elastofibroma from a 69-year-old white man was studied by light and electron microscopy. The lesion was comprised of abundant collagen fibers and numerous randomly disposed masses of amorphous elastinophilic material. Ultrastructurally, this material appeared to be derived from a markedly dense, finely fibrillar precursor secreted by fibroblasts and

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.

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

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.

Ultrastructure Organization of Human Trabeculae Assessed by 3D sSAXS and Relation to Bone Microarchitecture. [PDF]
PLoS ONE, 2016 Although the organization of bone ultrastructure, i.e. the orientation and arrangement of the mineralized collagen fibrils, has been in the focus of research for many years for cortical bone, and many models on the osteonal arrangement have been proposed,

Ultrastructure of a craniopharyngioma [PDF]
Cancer, 1971 A craniopharyngioma removed at surgery was examined by light and electron microscopy. The tumor consisted of both solid and cystic components. The cells lining the cysts, as well as those forming the solid masses, displayed desmosomes, tonofilaments, keratohyalin granules, and keratinization identical to those seen in the epidermis.

Ultrastructure expansion microscopy in Trypanosoma brucei. [PDF]
, 2021 The recently developed ultrastructure expansion microscopy (U-ExM) technique allows us to increase the spatial resolution within a cell or tissue for microscopic imaging through the physical expansion of the sample.
