چکیده

Resumo As parasitoses humanas como: malária, leishmanioses, doença de Chagas e tricomoníase são causadas por protozoários apresentam elevadas taxas prevalência morbimortalidade. Apesar dos números alarmantes, essas doenças negligenciadas, recebendo pouca atenção no desenvolvimento novos fármacos e, portanto, o combate dessas enfermidades permanece um objetivo a ser alcançado. A pesquisa básica tem papel fundamental para compreensão mecanismos celulares moleculares na busca alvos terapêuticos. Nesse contexto, esta revisão reúne as principais vias que os Plasmodium spp., Leishmania Trypanosoma cruzi Trichomonas vaginalis utilizam estabelecer infecção causar patogenicidade. Os descritos incluem: (i) adesão, invasão saída da célula hospedeira, (ii) evasão resposta imune do hospedeiro, (iii) comunicação celular mediada vesículas extracelulares, (iv) peptidases metabolismo redox, (v) morte inflamassomas. De forma geral, estudos avançados têm identificado proteínas, enzimas receptores, em nível molecular, desempenham papéis fundamentais estabelecimento constituem-se como potenciais terapêuticos tratamento, diagnóstico vacinas controlar erradicar parasitoses. Palavras-chave: patogênicos, biologia celular, virulência. Abstract The human parasitic diseases such as: malaria, Leishmaniasis, disease and trichomoniasis are caused by protozoa present high rates of prevalence morbimortality. However, despite the alarming numbers, these neglected, receiving little attention in development new drugs and, therefore, fight against remains goal to be achieved. Basic research plays role understanding cellular molecular mechanisms search for therapeutic targets. In this context, review brings together main pathways that use establish infection cause pathogenicity. described herein include: host cell adhesion, invasion egress, immune response evasion, communication mediated extracellular vesicles; redox metabolism, death inflammasomes. general, advanced studies have identified proteins, enzymes, receptors at level, which play key roles establishment represents potential targets treatment, diagnosis vaccines control eradicate diseases. Keywords: pathogenic protozoa; biology; virulence.

Estudo de mecanismos de segurança para proteção do roteamento em redes de sensores sem fio

Wireless Sensor Networks (WSN) are more subject to enemy action than conventional networks due to their hardware and energy constraints and due to hostile environment in which they can be inserted. This scenario is too favorable to denial of service attacks, especially in routing function, one critical function in any network. This work is focused in routing protecting in WSN. It presents a stu...

Mecanismos de Controle de Admissão Baseado em Medições em Redes IEEE 802.11e

Although the 802.11e extension of the IEEE 802.11 standard for wireless local area network was concerned to provide Quality of Service, such provisioning cannot be achieved without specific traffic control mechanisms. In this paper, the use of admission control based on measurement for QoS provision in 802.11e networks is evaluated. It is shown that QoS differentiation can be obtained with the ...
