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 ...
Controlled route to the fabrication of carbon and boron nitride nanoscrolls: A molecular dynamics investigation
Carbon nanoscrolls (graphene layers rolled up into papyrus-like tubular structures) are nanostructures with unique and interesting characteristics that could be exploited to build several new nanodevices. However, an ...
Structural re-arrangement in two hexanuclear CuII complexes: from a spin frustrated trigonal prism to a strongly coupled antiferromagnetic soluble ring complex with a porous tubular structure
(The Royal Society of Chemistry, 2014)
The addition of water to a chloroform solution of the Cu6 trigonal prism complex [Cu6(U6F)(U2OH)(U3OCH3)2(U2OCH3)2(3,5-Me2pz)6] (1) (3,5-Me2pz- = 3,5-dimethylpyrazolate) results in the formation of the Cu6 planar hexagonal ...
Deposition Form and Bioaccessibility of Keto-carotenoids from Mamey Sapote (Pouteria sapota), Red Bell Pepper (Capsicum annuum), and Sockeye Salmon (Oncorhynchus nerka) Filet
The ultrastructure and carotenoid-bearing structures of mamey sapote (Pouteria sapota) chromoplasts were elucidated using light and transmission electron microscopy and compared to carotenoid deposition forms in red bell ...
Morphology of the vas deferens of the budgerigar (Melopsittacus undulatus)
A morphological study of the budgerigar vas deferens was conducted to demonstrate the electron-microscopic features of its epithelial lining. The analysis showed that the vas deferens of the budgerigar was found to be of ...
Analise mecânica e microestrutural em estruturas tubulares aeronáuticas soldadas de aço ABNT 4130
(Universidade Estadual Paulista (UNESP), 2011)
Airplane Motor Cradles have a complex geometry, since they require different conbinations between different tubes and TIG welded in several angles. In T-25 aircraft and Universal T-27 Tucano (EMBRAER / FAB), besides having ...
