The salivary glands of the dipteran Chironomus tentans provide an elegant model system for the analysis of specific messenger ribonucleoprotein particles, the Balbiani Ring (BR) mRNP. BR mRNP particles contain long RNA transcripts of roughly 35-40 kb in size which possess a highly repetitive sequence. The diameter of the granular BR mRNP particles is around 50 nm and their geometry was meanwhil...

Ralstonia causes wilt diseases by colonizing xylem vessels and disrupting water transport. The dogma is that bacterial biomass clogs reduces the flow of sap due to abundance. However, physiological mechanism disruption during untested. Using a tomato pseudosolanacearum GMI1000 model, we visualized quantified spatiotemporal dynamics wilt. First, measured stomatal conductance leaflets on mock-ino...

Spatiotemporal aspects of filovirus entry and release are poorly understood. Lipid rafts act as functional platforms for multiple cellular signaling and trafficking processes. Here, we report the compartmentalization of Ebola and Marburg viral proteins within lipid rafts during viral assembly and budding. Filoviruses released from infected cells incorporated raft-associated molecules, suggestin...

the incorporation of boehmite nano-particles and its effects on the mechanical properties and bond strength of an experimental dental adhesive were studied.an adhesive solution containing ethanol, bis-gma, tmptma, hema and photo-initiator system (camphorquinone and dmaema) was prepared. silanized boehmite nano-particles were incorporated into the adhesive in different concentrations of 0, 0.2, ...

tomato ringspot virus (torsv) is a member of the genus nepovirus, family secoviridae, causing substantial economically declining in perennial crops, including stone fruits, worldwide. during the years 2008 and 2009 a total number of 414 symptomatic and asymptomatic leaf samples were randomly collected from different stone fruit trees including peach, apricot, plum and sour cherry from fars and ...

Rice yellow mottle virus (RYMV) is icosahedral in morphology and known to swell in vitro, but the biological function of swollen particles remains unknown. Anion-exchange chromatography was used to identify three markedly stable forms of RYMV particles from infected plants: (1) an unstable swollen form lacking Ca2+ and dependent upon basic pH; (2) a more stable transitional form lacking Ca2+ bu...

Nanocrystalline particles of Cerium Oxide (CeO2) have been prepared by the chemical precipitation method using Cerium nitrate and Urea with a molar ratio of 1:2. The results revealed that the formation of CeO2 fine particles is influenced by molar ratio of metal nitrates to fuel. Well faceted CeO2 nanoparticles, were synthesized by thermal-assisted dissociation ...
