Chromosome Vacuolization and Breakage
Archives of Internal Medicine, 1968The presence of vacuoles in the cytoplasm and in the nuclei of the cells of blood forming tissues has been long recognized as a feature of disturbed hematopoiesis. It is common to a variety of pathologic conditions. It has been encountered in association with administration of chloramphenicol, 1-4 with prolonged antimetabolite therapy, 5 in riboflavin ...

Vacuolization of the Neutrophil in Bacteremia
Archives of Internal Medicine, 1979We evaluated cytoplasmic vacuolization in the neutrophil as a marker of bacterial infection. We sought this phenomenon in 96 septic and nonseptic subjects. No significant differences in the extent of vacuolization were found among control patients, toxic patients without bacterial infections, and patients with bacterial infections in the absence of ...

Publisher Summary The vacuole is the most conspicuous organelle in plant cells. It can be defined operationally as a swollen terminally differentiated intracellular membrane-bound compartment of the secretory pathway, and the minimal requirement for the formation of vacuoles is the synthesis of a vacuolar membrane that contains the transporters ...

On the gas vacuoles of the halobacteria
Archiv f�r Mikrobiologie, 1967The cells of Halobacterium sp., strain 5, contain a large number of highly refractile bodies of the type which Petter (1932) suggested were gas-filled vacuoles. The present studies support Petter's contention, but the evidence for the exact chemical nature of the vacuole content is still indirect.

Pollen vacuoles and their significance
Planta, 2011Vacuoles of several types can be observed in pollen throughout its development. Their physiological significance reflects the complexity of the biological process leading to functional pollen grains. Vacuolisation always occurs during pollen development but when ripe pollen is shed the extensive translucent vacuoles present in the vegetative parts in ...

Protoplasma, 1997
The vacuole is often termed the lytic compartment of the plant cell. The yeast cell also possesses a vacuole containing acid hydrolases. In animal cells these enzymes are localized in the lysosome. Recent research suggests that there is good reason to regard these organelles as homologous in terms of protein transport.

Vacuoles and prevacuolar compartments
Current Opinion in Plant Biology, 2000Plant vacuoles are complex and dynamic organelles. Important advances have been made in our understanding of the transporters present in the tonoplast and of the molecular interactions that allow targeting to vacuoles. Despite these advances, markers that permit vacuoles to be defined unambiguously have not yet been identified.

Publisher Summary This chapter describes methods for studying different aspects of vacuole biogenesis and function. It presents three different approaches for visualizing the yeast vacuole: staining with vital dyes, using green fluorescent protein (GFP)-tagged vacuolar marker proteins, and immunofluorescence microscopy of formaldehyde-fixed cells ...

Nature, 1921
IN connection with previous correspondence on the mode of production of the contractile vacuole in Protozoa (NATURE, vol. cvi., pp. 343, 376, 441), I find that it is, in point of fact, Prof. Marcus Hartog to whom the credit of the osmotic view is to be given. In a communication to the British Association in 1888 (Rep., p. 714) this observer pointed out

1. The vacuole was studied under ordinary, phase contrast and dark ground illumination in yeast of varying ages. With the increasing age of the culture almost all cells appear vacuolated and more and more cells exhibit luminous contours to their vacuoles.
