The Biogenesis of Vacuoles: Insights from Microscopy

1997

Publisher Summary Vacuoles of plant cells were discovered with the early light microscope and, as meant by the etymology of the word, were subsequently defined as the cell space empty of cytoplasmic matter. As usual in experimental science, methodological and instrumental progress has delineated differently the present definitions of vacuoles, which largely depend on the tools and concepts used for their study. This chapter discusses the biogenesis of vacuoles. Biochemistry and physiology of the vacuole have been made possible by the isolation of intact vacuoles. A specific, although yet incomplete, set of soluble and membrane proteins with unique properties have been specifically ascribed …

Ultrastructure of differentiating hemocytes in the embryo of Oncopeltus fasciatus dallas (insecta, heteroptera).

1978

The hemocytes of Oncopeltus differentiate rather early during embryogenesis. They are segregated by the mesoderm soon after its formation (about 50h after egg deposition). Newly segregated hemocytes show the “typical” features of “embryonic” cells: many free ribosomes, a few strands of rough ER, the cisternae of which are considerably distended, electron lucent vacuoles around the periphery, and glycogen deposits. A few hours thereafter the hemocytes undergo striking subcellular changes. First, glycogen, electron lucent vacuoles and rough ER disappear and phagocytotic activity can be observed. Golgi complexes become well expressed and give rise to electron dense vesicles which fuse to large…

Dal Sud. Percorsi e mete di viaggio di Ernesto Basile (1876-1900)

2015

Come, dunque, studiare Ernesto Basile oggi e quale ambito della sua copiosa produzione analizzare? Alla luce dello stato degli studi odierni si potrebbe ritenere che possa essere stato detto tutto. Tuttavia, ci sono diversi ambiti che si offrono a ulteriori indagini, a nuove letture e ricerche. Tra questi, vi è quello dei viaggi, non irrilevante, per diverse ragioni. Una prima motivazione, che vale per Ernesto Basile così come per altri architetti, è quella più interna ed è strettamente legata alla natura stessa dell'architettura e dei luoghi, alla formazione continua dell'architetto e al ruolo che hanno i viaggi nel processo di costruzione o assimilazione del patrimonio di immagini e dei p…

8-N(3)-3'-biotinyl-ATP, a novel monofunctional reagent: differences in the F(1)- and V(1)-ATPases by means of the ATP analogue.

2001

A novel photoaffinity label, 8-N(3)-3'-biotinyl-ATP, has been synthesized. The introduction of an additional biotin residue is advantageous for easy detection of labeled proteins. This could be first tested by reaction with the F(1)-ATPase from the thermophilic bacterium PS3 (TF(1)). UV irradiation of TF(1) in the presence of 8-N(3)-3'-biotinyl-ATP results in a nucleotide-dependent binding of the analogue in the noncatalytic alpha and the catalytic beta subunits of TF(1), demonstrating the suitability of this analogue as a potential photoaffinity label. Reaction with the V(1)-ATPase, however, led to labeling of subunit E, which has been suggested as a structural and functional homologue of …
