The ATP requirement during RNA transcription by the RNA-dependent RNA polymerase associated with purified vesicular stomatitis virus was studied during chain initiation and chain elongation steps. Initiation of transcription in vitro has an apparent Km for ATP of approximately 500 micron, whereas the apparent Km for ATP during chain elongation is almost identical with those for the other three ...

Lupi et al. present, on p. 80–81, an interesting case report of dyshidrosiform palmo-plantar pemphigoid. They describe a 20-year-old man who had had itchy vesicles on his palms and soles for 1 year. Histologically, a subepi-dermal vesicle was seen, and direct immunofluorescence showed continuous linear deposition of IgG and C 3 at the dermal-epidermal junction. An enzyme-linked immuno-sorbent a...

Introducción. La neoplasia papilar intracolecística se caracteriza por el crecimiento exofítico del epitelio de la vesícula biliar hacia su interior. Casos clínicos. Presentamos dos casos clínicos con masa vesicular a quienes les realiza colecistectomía, dado riesgo que esos hallazgos sean pólipos vesiculares malignos. anatomía patológica certifica corresponden una intracolecística. Discusión. ...

Numerous, ongoing outbreaks in Brazilian swine herds have been characterized by vesicular lesions in sows and acute losses of neonatal piglets. The complete genome of Seneca Valley virus (SVV) was identified in vesicular fluid and sera of sows, providing evidence of association between SVV and vesicular disease and viraemia in affected animals.

In plants, newly synthesized fatty acids are either directly incorporated into glycerolipids in the plastid or exported and assembled into lipids at the endoplasmic reticulum (ER). ER-derived glycerolipids serve as building blocks for extraplastidic membranes. Alternatively, they can return to the plastid where their diacylglycerol backbone is incorporated into the glycerolipids of the photosyn...

Vesicular storage and subsequent release of neurotransmitters are the key processes of chemical signal transmission. In this process, vesicular neurotransmitter transporters are responsible for loading the signaling molecules. The use of a "clean biochemical" approach with purified, recombinant transporters has helped in the identification of novel vesicular neurotransmitter transporters and in...

Foot and mouth disease (FMD) is the most contagious disease of mammals and has a great potential for causing severe economic loss in susceptible cloven-hoofed animals. There are seven serotypes of FMD virus (FMDV), namely, O, A, C, SAT 1, SAT 2, SAT 3 and Asia 1. Infection with one serotype does not confer immunity against another. FMD cannot be differentiated clinically from other vesicular di...
