1. Analysis of radioprotection and antimutagenic effects of Ilex paraguariensis infusion and its component rutin
DNA repair pathways, cell cycle checkpoints, and redox protection systems are essential factors for securing genomic stability. The aim of the present study was to analyze the effect of Ilex paraguariensis (Ip) infusion and one of its polyphenolic components rutin on cellular and molecular damage induced by ionizing radiation. Ip is a beverage drank by most

2. Classical and alternative macrophages have impaired function during acute and chronic HIV-1 infection
Abstract Objectives: Three decades after HIV recognition and its association with AIDS development, many advances have emerged – especially related to prevention and treatment. Undoubtedly, the development of Highly Active Antiretroviral Therapy (HAART) dramatically changed the future of the syndrome that we know today. In the present study, we evaluate t

3. A Performance Evaluation of WLAN-Femtocell-LTE beyond the Capacity Crunch. Does Femtocell have to overcome WLAN or can they coexist in HetNets?
Abstract This paper originates from a practical experiment based on Mesh Networks. The promising results obtained from this experiment prompted us to discuss in greater depth whether Wireless Local Area Networks (WLAN) are still useful for current communications. This means that on the one hand femtocells can be defined as small base stations that use the sa

4. Atividade imunomoduladora da ouabaína no processo inflamatório agudo / OUABAIN IMMUNOMODULATORY ACTIVITY IN THE ACUTE INFLAMMATORY PROCESS.
Ouabain (OUA), a potent inhibitor of the Na+,K+-ATPase pump, was identified as an endogenous substance of human plasma. In recent years, ouabain was shown to affect various immunological processes. Mechanisms that involve cellular differentiation, proliferation, activation and migration, as well as inflammatory mediators release, are activated during inflamm

5. Recombinant vaccines and the development of new vaccine strategies
Vaccines were initially developed on an empirical basis, relying mostly on attenuation or inactivation of pathogens. Advances in immunology, molecular biology, biochemistry, genomics, and proteomics have added new perspectives to the vaccinology field. The use of recombinant proteins allows the targeting of immune responses focused against few protective ant

6. AvaliaÃÃo do potencial antitumoral e antiangiogÃnico de novos anÃlogos ftalimÃdicos da talidomida / EVALUATION OF THE ANTITUMOR AND ANTIANGIOGENIC POTENTIAL OF NEW FTHALIMIDES THALIDOMIDE ANALOGUES
The thalidomide was previously used to relieve gastric discomforts during pregnancy, and currently it is used for cancer treatment and inflammatory illnesses. Various phthalimides analogues of thalidomide have been researched for its antiangiogenic and immunemodulatory activity. In previous studies, these analogues showed absence of immunesuppressor activity

7. ATIVIDADE ANTI-INFLAMATÓRIA DE POLISSACARÍDEOS ISOLADOS DAS PLANTAS Caesalpinia ferrea E Azadirachta indica / ANTI-INFLAMMATORY ACTIVITY OF ISOLATED PLANT Polysaccharides Caesalpinia ferrea AND Azadirachta indica
Polysaccharides of higher plants form complex structures and multiple intermolecular interactions. They are noted for their immune system activities, being classified as exogenous modifiers of biological responses. However, the spectrum of activities is very large including the antiviral, antitumor, immunostimulant, anti-inflammatory, anticoagulant and antic

9. Alterações celulares, moleculares e funcionais de fígados de ratas Wistar tratadas com fatores hepatotróficos / Cellular, molecular and functional alterations in rat liver treated with hepatotrophic factors
Fatores hepatotróficos (FH) possuem a capacidade de promover aumento de massa hepática em ratos e diminuição da fibrose em animais cirróticos. Os FH podem ser importantes nos casos de ressecção e transplantes hepáticos no qual o fígado remanescente necessita de um volume considerável para exercer suas funções após a cirurgia. Objetivou-se neste

10. Effect of cyhalothrin on Ehrlich tumor growth and macrophage activity in mice
Cyhalothrin, a pyrethroid insecticide, induces stress-like symptoms, increases c-fos immunoreactivity in the paraventricular nucleus of the hypothalamus, and decreases innate immune responses in laboratory animals. Macrophages are key elements in cellular immune responses and operate at the tumor-host interface. This study investigated the relationship among
