The vomeronasal organ (VO) or the second olfactory organ has the form of paired epithelial pockets at the base of the nasal septum. In animals it has various functions including reception of pheromones mediating sexual, parental and social behavior. Human VO was considered to be rudimental until the last decade of the XXth century. Since then it was found… (More)
Fragments of the neural primordium of a new Notch mutant of Drosophila melanogaster produced in our laboratory were transplanted into the neural tube of embryos of 4 amphibian species (caudate and ecaudate) immediately after completion of neurulation. The grafts were identified by using a light microscope, scanning electron miscroscope, and in situ… (More)
The epiphysis is a gland containing firm extracellular bodies (brain sand) the number of which increases with age. Microscopy and roentgen microtomography showed that in some cases of schizophrenia the amount of brain sand decreases. In parallel, cytoplasm of pinealocytes appears to contain concrements of a new type--irregular hollow spheres of 0.1-1.5… (More)
Cells of the neural primordia of the Notch mutant ofDrosophila melanogaster are transplanted to the neural tube of four amphibian species and two mammalian species. It is shown that cells of the neural primordia of drosophila survive and differentiate in the amphibian and mammalian brain. Differentiated cells of the transplant establish axon-dendrite… (More)
Histological and morphometrical analysis of the brain and peripheral analyzers revealed proliferative migration abnormalities of brain development and neuron differentiation in mammals during a space flight, which can limit space exploration.
The study was carried out within the framework of a Russian-Canadian experiment aboard the Bion-10 satellite. The volume and surface area of the gray and white matter and ventricles of the brain, retina, olfactory placodes, the VIII nerve ganglia, and vascular plexus were measured inXenopus laevis which had been in a state of weight-lessness for 2 weeks… (More)
Experiments involving lower tetrapods demonstrate that the degree of skeletal demineralization in spaceflights is related to the type of environmental behaviour of the animal. Probably the sensing of support reaction decreases the negative effect of spaceflight upon the bone tissue.
This article will form part of a virtual special issue of the journal, presenting some highlights of the 12th Biennial Conference on High-Resolution X-ray Diffraction and Imaging (XTOP2014). Monochromatic computed microtomography using laboratory and synchrotron sources and X-ray fluorescence analysis for comprehensive analysis of structural changes in… (More)
