25. Performance of diagnostic biomarkers in predicting liver fibrosis among hepatitis C virus-infected Egyptian children
The aim of the present study was to identify specific markers that mirror liver fibrosis progression as an alternative to biopsy when biopsy is contraindicated, especially in children. After liver biopsies were performed, serum samples from 30 hepatitis C virus (HCV) paediatric patients (8-14 years) were analysed and compared with samples from 30 healthy sub

26. Antifibrotic effects of crocetin in scleroderma fibroblasts and in bleomycin-induced sclerotic mice
OBJECTIVE: To investigate the antifibrotic effects of crocetin in scleroderma fibroblasts and in sclerotic mice. METHODS: Skin fibroblasts that were isolated from three systemic scleroderma (SSc) patients and three healthy subjects were treated with crocetin (0.1, 1 or 10 μM). Cell proliferation was measured with an MTT assay. Alpha-smooth muscle actin w

27. SIRT1 negatively regulates amyloid-beta-induced inflammation via the NF-κB pathway
Chronic inflammation induced by amyloid-beta (Aβ) plays a key role in the development of age-related macular degeneration (AMD), and matrix metalloproteinase-9 (MMP-9), interleukin (IL)-6, and IL-8 may be associated with chronic inflammation in AMD. Sirtuin 1 (SIRT1) regulates inflammation via inhibition of nuclear factor-kappa B (NF-κB) signaling, and res

28. ImunoexpressÃo de metaloproteinases 2 e 14 e do inibidor TIMP-2 no cÃncer colorretal / Immunoexpression of metalloproteinases 2 and 14 and the inhibitor TIMP-2 in colorectal cancer
O cÃncer colorretal(CCR) Ã altamente prevalente nos paÃses mais ricos e industrializados. As metaloproteinases de matriz (MMPs) sÃo importantes enzimas que facilitam a invasÃo e disseminaÃÃo do tumor em vÃrios tipos de cÃncer, inclusive o colorretal. Os inibidores teciduais de metaloproteinases (TIMPs) sÃo os principais inativadores fisiolÃgicos d

29. Análise da expressão das metaloproteinases 2 e 9 e seus reguladores no câncer de bexiga / Expression of metalloproteinases 2 and 9 and their regulator genes in bladder cancer
Introdução: O Carcinoma Urotelial de Bexiga (CUB) é o segundo tumor urológico mais prevalente no Brasil. Devido ao elevado custo médico no processo que envolve seu diagnóstico, tratamento e seguimento, o CUB é um dos tipos de tumores mais caros para os sistemas de saúde. Embora existam fatores prognósticos definidos, como o estadiamento patológico,

30. Prostate-specific membrane antigen can promote in vivo osseous metastasis of prostate cancer cells in mice
Reports remain insufficient on whether and how prostate-specific membrane antigen (PSMA) can influence in vivo osseous metastasis of prostate cancer (PCa). In the present study, the authors induced stable expression of PSMA in mouse PCa cell line RM-1. In vivo osseous metastasis was induced in 37 6-week-old female C57BL/6 mice weighing 22.45 ± 0.456 g.

31. Underexpression of MMP-2 and its regulators, TIMP2, MT1-MMP and IL-8, is associated with prostate cancer
OBJECTIVE: Extracellular matrix homeostasis is strictly maintained by a coordinated balance between the expression of metalloproteinases (MMPs) and their regulators. The purpose of this study was to investigate whether MMP-2 and its specific regulators, TIMP-2, MT1-MMP and IL-8, are expressed in a reproducible, specific pattern and if the profiles are relate

32. Estudo da fototerapia de baixa potência no modelo de inflamação aguda induzida no joelho de ratos. / Study of the fototerapia of low power in the model of induced acute inflammation in the knee of rats.
The acute arthritis of the knee is a common joint disorder, and its prevalence increases in parallel with increasing age, is one of the most frequent causes of pain, loss of function and removal of work activities in adults. Many treatments are used to treat pain associated with rheumatoid arthritis. Nonsteroidal anti-inflammatory drugs (NSAIDs), anti-rheuma

33. Estudo da pele do campo cancerizável antes e após a terapia fotodinâmica através dos métodos clínicos, histopatológicos e imunohistoquímicos / Clinical, histopathological and immunohistochemical assessment of human skin field cancerization before and after photodynamic therapy
O conceito de campo de cancerização, em dermatologia, sugere que a pele fotodanificada tem maior potencial para o desenvolvimento de neoplasias cutâneas. A terapia fotodinâmica (TFD) é um método não invasivo para o tratamento de queratoses actínicas (QA) múltiplas, possibilitando a abordagem de todo o campo. Vinte e seis pacientes com múltiplas QAs

34. Eventos moleculares associados ao aumento gengival induzido por ciclosporina A são atenuados pela superexpressão de Smad7 / Molecular events associated with cyclosporin A induced gingival overgrowth are attenuated by Smad 7 overexpression
O aumento gengival induzido por ciclosporina A (CsA) é causado por um acúmulo excessivo de matriz extracelular, resultado da ação do fator de crescimento transformante-beta 1 (TGF-ß1) sobre a atividade dos fibroblastos gengivais. O presente estudo investigou in vitro os efeitos da superexpressão de Smad7, um inibidor da sinalização de TGF-ß1, nos ev

35. Inhibition of STAT3 by RNA interference suppresses angiogenesis in colorectal carcinoma
In order to investigate signal transduction and activation of transcription 3 (STAT3) signaling on angiogenesis in colorectal carcinoma (CRC) after inhibiting STAT3 expression, we constructed the HT-29-shSTAT3 cell line by lentivirus-mediated RNAi. Cell growth was assessed with MTT and the cell cycle distribution by flow cytometry. CRC nude mouse models were

36. Associação entre haplótipos de metaloproteinase-9 de matriz extracelular (MMP-9) e obesidade infantil : efeitos sobre a concentração plasmática de MMP-9 / Association between haplotypes of matrix metalloproteinase-9 extracellular matrix (MMP-9) and childhood obesity : effects on plasma concentration of MMP-9
The childhood obesity is important risk factor for cardiovascular diseases, in particular, atherosclerose. This condition is characterized by the accumulation of lipids and fibrous elements in the large arteries in which inflammatory mechanisms and vascular remodeling are involved. In this context, matrix metalloproteinase 9 (MMP-9) - endopeptidade capable o
