1. Gross morphology and ultrastructure of the female reproductive system of Diaphorina citri (Hemiptera: Liviidae)
The morphological traits of the female reproductive system of Diaphorina citri were examined in detail. Diaphorina citri has telotrophic ovaries with ovarioles organized as a "bouquet", displaying a rudimentary terminal filament and a syncytial tropharium. The vitellarium carries a single growing oocyte at each maturation cycle, which is connected with the t

2. Detection of introduced sessile species on the near shore continental shelf in southern Brazil
Invasion by marine species, often considered a grave threat to marine ecosystems, occurs throughout the world as a consequence of many anthropogenic activities. In coastal Paraná, many factors including shipping, aquaculture and the use of artificial substrates provide suitable environments for the establishment and rapid spread of introduced marine species

3. Molecular mechanisms of Trypanosoma cruzi infection by oral route
Frequent reports on outbreaks of acute Chagas' disease by ingestion of food contaminated with parasites from triatomine insects illustrate the importance of this mode of transmission. Studies on oral Trypanosoma cruzi infection in mice have indicated that metacyclic trypomastigotes invade the gastric mucosal epithelium. A key molecule in this process is gp82

4. A comunidade de peixes dos reservatórios dos trechos médio e baixo rio Tietê, com ênfase nas espécies Plagioscion squamosissimus e Geophagus surinamensis. / Fish community of the reservoirs located on middle and low Tietê River, with emphasis in the introduced species Plagioscion squamosissimus and Geophagus surinamensis.
From sixties, the fish species introduction has been being a constant event in the reservoir system located on middle and low Tietê River - SP, which resulted the success introduction of Plagiosicon squamosissimus and Cichla cf. ocellaris in all these reservoirs. According to this context, the present work objectified characterize the fish community, with f

5. Comunidade urbana e desenvolvimento local em área de invasão: bairro Taquarussu Campo Grande MS
The objective of this paper was to demarcate and to study the Taquarussu Urban Community, which is delimited by the streets Turiassu, Patriarca, Yporã and São Roque. The community is situated in the geography space of the square number 28 in Taquaussu district, around the North-south route, and it is also close to Jacy, Guanandy and Aero Rancho districts,

6. Proteção imunológica contra a formação de cistos cerebrais em camundongos vacinados pela via nasal com proteínas recombinates de Toxoplasma gondii
Toxoplasma gondii is a protozoan parasite which can invade and reside in a wide range of host cells. It can infect all warm-blooded animals, including human being. Parasite invasion is associated with protein secretion from three organelles: micronemes, rhoptries and dense granules. These excreted/secreted antigens were highly immunogenic in humans and roden

7. A New Cruzipain-Mediated Pathway of Human Cell Invasion by Trypanosoma cruzi Requires Trypomastigote Membranes
The intracellular protozoan Trypanosoma cruzi causes Chagas' disease, a chronic illness associated with cardiomyopathy and digestive disorders. This pathogen invades mammalian cells by signaling them through multiple transduction pathways. We previously showed that cruzipain, the main cysteine protease of T. cruzi, promotes host cell invasion by activating k

8. Fibronectin-Facilitated Invasion of T84 Eukaryotic Cells by Campylobacter jejuni Occurs Preferentially at the Basolateral Cell Surface
Previous studies have indicated that the ability to bind to fibronectin is a key feature in successful cell invasion by Campylobacter jejuni. Given the spatial distribution of fibronectin and the architecture of the epithelium, this suggests the possibility that C. jejuni cell invasion might preferentially occur at the basolateral cell surface. To test this

9. Intraportal endovascular ultrasonography in the diagnosis of portal vein invasion by pancreatobiliary carcinoma.
OBJECTIVE: The purpose of this study was to determine the value of intraportal endovascular ultrasonography (IPEUS) in the diagnosis of portal vein invasion by pancreatobiliary carcinoma. The authors reported their experiences with this new technique and compared it with conventional imaging technologies, such as portography and computed tomography (CT). SUM

10. Pathogenesis of bloodstream invasion with Haemophilus influenzae type b.
Possible route(s) by which encapsulated bacteria invade the blood from the nasopharynx include (i) the direct invasion of submucosal blood vessels and (ii) clearance via lymphatics to regional nodes followed by bloodstream invasion. These possibilities were investigated in rats after intranasal inoculation with 10(5) Haemophilus influenzae type b. Within 24

11. Subdural spread of medulloblastoma: case report
A case of widespread intracranial subdural invasion by medulloblastoma is presented. The origin of the metastases would seem to be a large subfrontal tumour mass, with dissemination through the subdural space. This appears to be the first report of intracranial spread of tumour by this route.

12. Targeted disruption of an erythrocyte binding antigen in Plasmodium falciparum is associated with a switch toward a sialic acid-independent pathway of invasion
Erythrocyte invasion by Plasmodium requires molecules present both on the merozoite surface and within the specialized organelles of the apical complex. The Plasmodium erythrocyte binding protein family includes the Plasmodium falciparum sialic acid-binding protein, EBA-175 (erythrocyte binding antigen-175), which binds sialic acid present on glycophorin A o
