Model of chromosome associations in mus domesticus spermatocytes
(Society of Biology of Chile, 2010)
Understanding the spatial organization of the chromosomes in meiotic nuclei is crucial to our knowledge of the genome's functional regulation, stability and evolution. This study examined the nuclear architecture of Mus ...
Structural associations between organelle membranes in nectary parenchyma cells
(2018-05-01)
Main conclusion: The close association between membranes and organelles, and the intense chloroplast remodeling in parenchyma cells of extrafloral nectaries occurred only at the secretion time and suggest a relationship ...

Single-channel recording of inositol trisphosphate receptor in the isolated nucleus of a muscle cell line
(SOCIEDAD BIOLGIA CHILE, 2006)
Nuclear calcium appears to have an important role in the regulation of gene expression in many cells, but the mechanisms involved in controlling nuclear Ca2+ signaling are controversial and still poorly understood. We have ...
Structural Biology and Regulation of Protein Import into the Nucleus
(Elsevier B.V., 2016-05-22)
Proteins are translated in the cytoplasm, but many need to access the nucleus to perform their functions. Understanding how these nuclear proteins are transported through the nuclear envelope and how the import processes ...
Primary biliary cirrhosis and the nuclear pore complex
Experimental models of autoimmune diseases have led to the conclusion that an immune response to nuclear antigens is a sentinel marker for loss of tolerance and potential tissue damage. Various proteins are targets of ...
Acrosomal biogenesis in human globozoospermia: Immunocytochemical, ultrastructural and proteomic studies
(Oxford University Press, 2012-06)
Background Acrosome biogenesis is a key event in sperm differentiation that depends on the proper interaction between the Golgi complex and the nuclear envelope of early spermatids. We studied the development, structure ...
Human preimplantation development in vivo: ultrastructural observations.
(1992)
The ultrastructure of a 2-cell, 4-cell, 7-cell and 16-cell human embryos fertilised and developed in vivo were compared using transmission electron microscopy. Among the structures which exhibited more notable changes ...
Análise conformacional de 3-halo-derivados da 2-pirrolidinona por espectroscopia de ressonância magnética nuclear e cálculos de estrutura eletrônica
(Universidade Estadual de MaringáBrasilDepartamento de QuímicaPrograma de Pós-Graduação em QuímicaMaringá, PRCentro de Ciências Exatas, 2018)
