Finding of two undescribed species, closely related to Eresiomera paradoxa (Schultze, 1917) in Liberia and the Democratic Repubic of Congo led the authors to revise the material available in the African Butterfly Reserarch Institute (ABRI), Nairobi. Examination of the material revealed that the placement of E. paradoxa and the related species neither in the genus Eresiomera Clench, 1965, nor in...

Attachment of a flexible coil on the mid-part of a rigid rod block generates T-shaped rod-coil block molecules that self-assemble into a stepped column. These layers, in turn, self-curve into a spiral column with tunable core structure in the solid state.

Spindle- or lemon-shaped viruses that infect archaea have been observed in diverse environments around the globe. Due to highly pleomorphic nature of these virions, which frequently can be found with cylindrical tails emanating from spindle-shaped body, structural studies remarkable capsids challenging. We determined atomic structure capsid Sulfolobus monocaudavirus 1, a virus infects hosts liv...

Non-hollow In(2)O(3) particles with hexagonal rod- and disk-shapes are generated from the calcination of porous CPPs; however, elongated hexagon-, ellipsoid-, and rod-shaped hollow In(2)O(3) particles are formed from the calcination of non-porous CPPs.

This Application Note describes an alternative process for bacterial cell counting using on-chip fl ow cytometry with the Agilent 2100 Bioanalyzer system. This procedure is described with three different kinds of prokaryotes: Escherichia coli (gram-negative, rod-shaped), Pseudomonas aeruginosa (gram-negative, rod-shaped), and Staphylococcus aureus (gram-positive, coccal). As a reference for bac...

The Benyviridae is a family of multipartite plant viruses with rod-shaped virions. Genomes are segmented and comprised of single-stranded, positive-sense RNAs, each with a 5' m7G cap. Unlike rod-shaped viruses classified in the Virgaviridae family, the genome segments have a 3' polyA tract and there is post-translational cleavage of the viral replicase. The better-known members are transmitted ...

On a roll: Attachment of flexible coils to the middle of a rigid rod generates T-shaped rod-coil molecules that self-assemble into layers that roll up to form filled cylindrical and hollow tubular scrolls, depending on the coil length, in the solid state (see picture); the rods are arranged parallel to the layer plane.

Brain microglial morphology relates to function, with ramified microglia surveying the micro-environment and amoeboid microglia engulfing debris. One subgroup of microglia, rod microglia, have been observed in a number of pathological conditions, however neither a function nor specific morphology has been defined. Historically, rod microglia have been described intermittently as cells with a sa...

By comparing the dimensions and DNA contents of normal rod-shaped Escherichia coli with those of mutants that grow as spheres or ellipsoids, we have determined that two parameters remain unchanged: the DNA/mass ratio and the average cell length (diameter, for spherical cells). In consequence, the average volumes and DNA contents of the spherical mutant cells are about four to six times greater ...

Cell shape in most eubacteria is maintained by a tough external peptidoglycan cell wall. Recently, cell shape determining proteins of the MreB family were shown to form helical, actin-like cables in the cell. We used a fluorescent derivative of the antibiotic vancomycin as a probe for nascent peptidoglycan synthesis in unfixed cells of various Gram-positive bacteria. In the rod-shaped bacterium...
