The classical mitochondrial ultrastructural features, consisting of an outer membrane and an inner membrane containing invaginations that comprise the matrix-rich cristae, are specifically modified in a tissue-specific manner in order to meet cellular-explicit energy demands.
Electron microscopical findings revealed that CAPE (22 mg/kg and 34 mg/kg) did not affect the ultrastructure of control mitochondria--they showed normal mitochondrial ultrastructure--parallel cristae, uniform matrix, and uninterrupted outer membrane.
The special topic is mitochondria, with papers on mitochondrial fusion, fission, and cristae remodeling as key mediators of cellular function; and supramolecular organization of respiratory complexes.
In further experiments with the flies, the research team found that ATP synthase was essential to normal stem cell development, directly controlling the growth and maintenance of the inner membranes inside mitochondria, called cristae, as the cells continue to divide and form the specific cell components that make up an egg, or female germ cell.
The subgenus Oppiella (Perspicuoppia) is well characterized by anterior margin of notogaster with two pairs of protuberances, notogastral cristae and humeral process (SubIas and Arillo, 2001).
After the three-month treatment, the researchers looked at changes in mitochondria volume and the abundance of cristae, which are internal compartments of mitochondria that are necessary for efficient function of the mitochondria, and measurable by electron microscopy.
Head angular velocity is measured by the cristae of the semicircular canals, while the maculae of the statolabyrinth (utricle and saccule) register linear acceleration and changes in the gravitational force.
