13. Evaluation of Wondfo influenza A&B fast test based on immunochromatography assay for rapid diagnosis of influenza A H1N1
Influenza viruses cause significant morbidity and mortality in both children and adults during local outbreaks or epidemics. Therefore, a rapid test for influenza A&B would be useful. This study was conducted to evaluate the clinical performance of the Wondfo influenza A&B test for rapid diagnosis of influenza A H1N1 Infection. The rapid testing assay could

14. InfecÃÃo latente por mycobacterium tuberculosis em portadores de infecÃÃo por HIV/AIDS: anÃlise atravÃs do uso de teste tuberculÃnico e teste de liberaÃÃo de interferon-gama / Latent infection by mycobacterium tuberculosis in patients with HIV / AIDS: analysis through the use of tuberculin test and interferon-gamma release
People living with HIV have an enhanced chance to develop and to die of tuberculosis (TB). Many studies demonstrate that chemoprophylaxis for latent tuberculosis infection (LTBI) reduces the progression to active TB. Indeed, the diagnosis of LTBI is controversial. In Brazil, the only test approved for use is the tuberculin skin test (TST), however, this test

15. In search of a tolerance-induction strategy for cow's milk allergies: significant reduction of beta-lactoglobulin allergenicity via transglutaminase/cysteine polymerization
OBJECTIVE: To explore the use of β-lactoglobulin polymerized using microbial transglutaminase and heating to identify whether protein polymerization could reduce in vivo allergenicity and maintain in vitro and ex vivo immunoreactivity for use in tolerance-induction protocols. METHODS: Based on previous protocols applied in mice and children, we performed in

16. Biofilm formation and binding specificities of CFA/I, CFA/II and CS2 adhesions of Enterotoxigenic Escherichia coli and CfaE-R181A mutant
Enterotoxigenic Escherichia coli (ETEC) strains are leading causes of childhood diarrhea in developing countries. Adhesion is the first step in pathogenesis of ETEC infections and ETEC pili designated colonization factor antigens (CFAs) are believed to be important in the biofim formation, colonization and host cell adhesions. As a first step, we have determ

17. Reduced occurrence of programmed cell death and gliosis in the retinas of juvenile rabbits after shortterm treatment with intravitreous bevacizumab
OBJECTIVE: Bevacizumab has been widely used as a vascular endothelial growth factor antagonist in the treatment of retinal vasoproliferative disorders in adults and, more recently, in infants with retinopathy of prematurity. Recently, it has been proposed that vascular endothelial growth factor acts as a protective factor for neurons and glial cells, particu

18. Estudos funcionais da proteína reguladora humana Ki-1/57 e seus parceiros de interação / Functional studies of the human regulatory protein Ki-1/57 and its interaction partners
The protein Ki-1/57 was discovered through cross reactivity of the monoclonal antibody Ki-1 in cells of Hodgkin lymphoma. Previously studies demonstrated that Ki-1/57 interacts with RACK-1 protein, undergoes phosphorylation by PKCs and methylation by PRMT1, an arginine methyltransferase that modulates several RNA binding proteins. Studies have shown that Ki-

19. Identificação de herpesvírus bovino em amostras de cérebro / Identification of bovine herpesvirus in brain samples
Herpetic meningoencephalitis is an infection of the central nervous system caused by bovine herpesvirus 5 (BoHV-5) despite BoHV-1 also being associated with this pathology. The course of the disease is usually fatal. Meningoencephalitis has caused significant economic burden to the Brazilian cattle industry due to its high mortality rate, especially in young

20. Supraorganized collagen enhances Schwann cell reactivity and organization in vitro
We investigated the reactivity and expression of basal lamina collagen by Schwann cells (SCs) cultivated on a supraorganized bovine-derived collagen substrate. SC cultures were obtained from sciatic nerves of neonatal Sprague-Dawley rats and seeded on 24-well culture plates containing collagen substrate. The homogeneity of the cultures was evaluated with an

21. Immunohistochemical staining of Langerhans cells in HPV-positive and HPV-negative cases of oral squamous cells carcinoma
The Human Papillomavirus (HPV) has been strongly implicated in development of some cases of oral squamous cell carcinoma (OSCC). However, the immunological system somehow reacts against the presence of this virus. Among the cells involved in such mechanism of defense Langerhans cells (LC) stand out, which are responsible for processing and presenting antigen

22. Vimentin and laminin are altered on cheek pouch microvessels of streptozotocin-induced diabetic hamsters
OBJECTIVE: Normal endothelial cells respond to shear stress by elongating and aligning in the direction of fluid flow. Hyperglycemia impairs this response and contributes to microvascular complications, which result in deleterious effects to the endothelium. This work aimed to evaluate cheek pouch microvessel morphological characteristics, reactivity, permea

23. Identificação de alvos antigênicos na ATP difosfohidrolase solúvel de Schistosoma mansoni e possível aplicação funcional de peptídeos sintéticos
The antigenicity of both soluble S. mansoni ATP diphosphohydrolase and membraneassociated isoforms has been recently described. Cross-immunoreactivity between potato apyrase and IgG antibody from S. mansoni-infected mice or schistosomiasis patients strongly suggested that the epitopes shared between the vegetable and parasite proteins are antigenic. By bioin

24. Cell toxicity in vitro analysis of PVC tubes consecutively submitted to gamma-rays and ethylene oxide sterilization / Análise in vitro da toxicidade celular de tubos de PVC esterilizados consecutivamente em raios gama e óxido de etileno
In 1967, a letter sent to the British Medical Journal reported that the re-sterilization with Ethylene Oxide (EtO) of previously irradiated Polyvinyl Chloride (PVC) formed large amounts of ethylene chlorohydrin, a highly toxic compound. Even though it did not present measured data, this letter initiated a controversy that still divide the opinion of research
