1. Intrafollicular barriers and cellular interactions during ovarian follicle development
Abstract Follicles are composed of different interdependent cell types including oocytes, cumulus, granulosa, and theca cells. Follicular cells and oocytes exchange signaling molecules from the beginning of the development of the primordial follicles until the moment of ovulation. The follicular structure transforms during folliculogenesis; barriers form bet

2. Caracterização batimétrica e fisicooceanográfica do canal de acesso ao porto de Cabedelo/PB: uma análise ambiental ao derrame de óleo
The State of Paraíba is one of the most dynamic states of Brazil, strategically located in the northeast, is notable for the excellent potential for integration of different transportation modes forming the states of Rio Grande do Norte, Pernambuco and Alagoas. The dynamic that occurs with port activity causes changes in the space where it is installed. And

3. Movimento bidirecional no transporte intracelular mediado por motores moleculares / Bidirectional movement in the intracellular transport mediated by molecular motors
In this work we present a theoretical model to describe aspects of the bidirectional movement performed by intracellular structures (vesicles, organelles, viruses etc, to which we refer here simply as "vesicles"), observed essentially at in vivo experiments. This nondifusive movement is characterized by rapid inversions in direction and is capable of creatin

4. Simulação orientada a objeto do transporte pneumatico
Particle transportation by a gas stream, commonly named as pneumatic conveying, has been ftequently used in a large variety of industrial processes. This is due not only to the diversity of materiais produced and handled in a granulated form, as also to the great number of possible applications of that operation, which includes since the simple displacement

6. A motility in the eukaryotic flagellum unrelated to flagellar beating.
We report a motility in the flagella of the green alga Chlamydomonas that is unrelated to dynein-based flagellar beating. This motility, referred to as intraflagellar transport, was observed as the rapid bidirectional movement of granule-like particles along the length of the flagella. Intraflagellar transport could be experimentally separated from other, pr

7. Herpesviruses use bidirectional fast-axonal transport to spread in sensory neurons
Alpha herpesviruses infect the vertebrate nervous system resulting in either mild recurrent lesions in mucosal epithelia or fatal encephalitis. Movement of virions within the nervous system is a critical factor in the outcome of infection; however, the dynamics of individual virion transport have never been assessed. Here we visualized and tracked indiv

8. GAL4 directs nucleosome sliding induced by NURF
The Drosophila nucleosome remodeling factor (NURF) is an imitation switch (ISWI)-containing chromatin remodeling complex that can catalyze nucleosome repositioning at promoter regions to regulate access by the transcription machinery. Mononucleosomes reconstituted in vitro by salt dialysis adopt an ensemble of translational positions on DNA templates. NURF i

9. Membrane assembly: movement of phosphatidylserine between the cytoplasmic and outer membranes of Escherichia coli.
Phosphatidylserine, normally a trace phospholipid in Escherichia coli, accumulates at high levels in temperature-sensitive phosphatidylserine decarboxylase mutants at nonpermissive temperatures. The intracellular localization of this phospholipid has now been determined. All of the accumulated phosphatidylserine is membrane bound and is distributed about equ

10. A monoclonal antibody against kinesin inhibits both anterograde and retrograde fast axonal transport in squid axoplasm.
One of our monoclonal antibodies against the heavy chain of bovine kinesin (H2) also recognized the heavy chain of squid kinesin. The immunofluorescence pattern of H2 in axoplasm was similar to that seen in mammalian cells with antibodies specific for kinesin light and heavy chains, indicating that squid kinesin is also concentrated on membrane-bounded organ

11. Replication of polyoma DNA in isolated nuclei: analysis of replication fork movement.
The movement of replication forks during polyoma DNA synthesis in isolated nuclei was analyzed by digesting newly synthesized DNA with the restriction endonuclease HpaII which cleaves polyoma DNA into eight unique fragments. The terminus of in vitro DNA synthesis was identified by cleaving newly completed molecules with HpaII. The distribution of label in th

12. Reconstitution of ATP-dependent Movement of Endocytic Vesicles Along Microtubules In Vitro: An Oscillatory Bidirectional ProcessV⃞
We have previously used the asialoglycoprotein receptor system to elucidate the pathway of hepatocytic processing of ligands such as asialoorosomucoid (ASOR). These studies suggested that endocytic vesicles bind to and travel along microtubules under the control of molecular motors such as cytoplasmic dynein. We now report reconstitution of this process in v
