the effect and arrangement of cytoskeleton (microtubules, microfilaments and neurofilaments) in neurulation of chick embryo examined by immunoperoxidase method from stage 6 to stage 12. the results were as follows: 1) microtubules aggregated in the perinuclear region from which they radiated to take longitudinal course beneath the membrane. 2) microfilaments were aggregated in the apical ends (...

The nuclear morphology of eukaryotic cells is determined by the interplay between lamina forming skeleton, chromatin inside nucleus, and coupling with cytoskeleton. Nuclear alterations are often associated pathological conditions as in Hutchinson-Gilford progeria syndrome (HGPS), which a mutation lamin A gene yields an altered form protein, named progerin, aberrant shape. While genetic molecula...

Abstract Lower temperatures delayed development of systemic symptoms by Cauliflower mosaic virus (CaMV) in two different plant hosts. However, lower temperature exposure increased CaMV nucleic acid levels leaves systemically-infected turnips. Furthermore, altered the formation aggregates formed major inclusion body (IB) protein, P6. Finally, architecture actin cytoskeleton. These data may sugge...

methods campylobacter jejuni atcc 33291 and seven isolates donated from instituto de biotecnologia were used in this study. the presence of cdt genes in c. jejuni strains was determined by pcr. to evaluate the effect of cdt, hela cells were treated with bacterial lysate, and the damage and morphological changes were analyzed by microscopy, immunofluorescence staining, and flow cytometry. to eva...

Abstract Developing tissues need to pattern themselves in space and time. A prevalent mechanism achieve this are pulsatile active stresses generated by the actin cytoskeleton. Active gel theory is a powerful tool model dynamics of cytoskeletal formation. In theoretical models, influence viscoelastic nature cytoskeleton has so far only been investigated incorporation one relaxation time scale. H...
