1. PELVIC INJURY IN CHILDHOOD: WHAT IS ITS CURRENT IMPORTANCE?
ABSTRACT Objective: The purpose of this study was to assess the importance of pelvic fractures in childhood by analyzing epidemiological characteristics and associated injuries. Methods: This is a retrospective study performed between 2002 and 2012 at two trauma referral centers in São Paulo. We identified 25 patients aged 16 years old or younger with p

2. MARCAÇÃO DE TRÁFEGO EM REDES DIFFSERV / TRAFFIC MARKING IN DIFFSERV NETWORKS
A crescente demanda por aplicações em tempo real tem aumentado a necessidade de fornecimento de QoS na Internet. A arquitetura de Serviços Diferenciados (DiffServ) é uma proposta apresentada pelo IETF para suprir a qualidade de serviço necessária. Resultados de pesquisas, mostram que os componentes da arquitetura DiffServ não distribuem de forma justa

3. A deficiency of the small GTPase rab8 inhibits membrane traffic in developing neurons.
One of the major activities of developing neurons is the transport of new membrane to the growing axon. Candidates for playing a key role in the regulation of this intense traffic are the small GTP-binding proteins of the rab family. We have used hippocampal neurons in culture and analyzed membrane traffic activity after suppressing the expression of the sma

4. Mouse Polyomavirus Utilizes Recycling Endosomes for a Traffic Pathway Independent of COPI Vesicle Transport
Mouse polyomavirus enters host cells internalized, similar to simian virus 40 (SV40), in smooth monopinocytic vesicles, the movement of which is associated with transient actin disorganization. The major capsid protein (VP1) of the incoming polyomavirus accumulates on membranes around the cell nucleus. Here we show that unlike SV40, mouse polyomavirus infect

5. Diacylglycerol Kinase δ Suppresses ER-to-Golgi Traffic via Its SAM and PH Domains
We report here that the anterograde transport from the endoplasmic reticulum (ER) to the Golgi was markedly suppressed by diacylglycerol kinase δ (DGKδ) that uniquely possesses a pleckstrin homology (PH) and a sterile α motif (SAM) domain. A low-level expression of DGKδ in NIH3T3 cells caused redistribution into the ER of the marker proteins of the

6. Interferon-gamma regulates an antigen specific for endothelial cells involved in lymphocyte traffic.
One of the most striking examples of localized vascular differentiation is exhibited by specialized lymphoid organ venules that mediate the extravasation of circulating lymphocytes from the blood. These vessels are characterized by cuboidal or "high" endothelial cell morphology and are unique in their functional capacity to interact with migrating lymphocyte

7. NEURONAL DYNAMICS AND AXONAL FLOW, IV. BLOCKAGE OF INTRA-AXONAL ENZYME TRANSPORT BY COLCHICINE*
The fact that the nucleated center of the nerve cell is the major source of the macromolecular materials required in the maintenance and function of the whole neuron requires the operation of a steady cellulifugal convection of these supplies into and down the nerve fiber. This proximo-distal traffic has been firmly established, but the mechanisms involved i

8. Analysis of the role of p200-containing vesicles in post-Golgi traffic.
p200 is a cytoplasmic protein that associates with vesicles budding from the trans-golgi network (TGN). The protein was identified by a monoclonal antibody AD7. We have used this antibody to analyze whether p200 functions in exocytic transport from the TGN to the apical or basolateral plasma membrane in Madin-Darby canine kidney cells. We found that transpor

9. The Dynamics of Golgi Protein Traffic Visualized in Living Yeast Cells
We describe for the first time the visualization of Golgi membranes in living yeast cells, using green fluorescent protein (GFP) chimeras. Late and early Golgi markers are present in distinct sets of scattered, moving cisternae. The immediate effects of temperature-sensitive mutations on the distribution of these markers give clues to the transport processes

10. Cellular vacuoles induced by Helicobacter pylori originate from late endosomal compartments.
Pathogenic strains of Helicobacter pylori cause progressive vacuolation and death of epithelial cells. To identify the nature of vacuoles, the distribution of markers of various membrane traffic compartments was studied. Vacuoles derive from the endocytic pathway since they include the fluid-phase marker Lucifer yellow. Early endosome markers such as rab5, t

11. Selective Perturbation of Apical Membrane Traffic by Expression of Influenza M2, an Acid-activated Ion Channel, in Polarized Madin–Darby Canine Kidney Cells
The function of acidification along the endocytic pathway is not well understood, in part because the perturbants used to modify compartmental pH have global effects and in some cases alter cytoplasmic pH. We have used a new approach to study the effect of pH perturbation on postendocytic traffic in polarized Madin–Darby canine kidney (MDCK) cells. Influen

12. The Rice α-Amylase Glycoprotein Is Targeted from the Golgi Apparatus through the Secretory Pathway to the Plastids[W][OA]
The well-characterized secretory glycoprotein, rice (Oryza sativa) α-amylase isoform I-1 (AmyI-1), was localized within the plastids and proved to be involved in the degradation of starch granules in the organelles of rice cells. In addition, a large portion of transiently expressed AmyI-1 fused to green fluorescent protein (AmyI-1-GFP) colocalized with a s
