Avaliação da expressão gênica de MMPs e TIMPs modulados por RECK e SPARC durante o desenvolvimento ovariano e a foliculogênese em ratas

O remodelamento da matriz extracelular (MEC), um importante componente dos organismos multicelulares, relaciona-se diretamente com o desenvolvimento embrionário, a angiogênese, a morfogênese de órgãos e a formação de cartilagens. Especificamente nos ovários, este remodelamento permite a ocorrência dos diversos eventos observados no ciclo ovariano, a citar: o crescimento folicular, a ovulação e a formação e regressão do corpo lúteo. A reorganização tecidual advinda destes eventos é regulada, em parte, pela ação de enzimas proteolíticas conhecidas como metaloproteinases de matriz (MMPs) e de seus inibidores (TIMPs e RECK) (revisado por Curry et al., 2003). Atualmente, o remodelamento da MEC pelo sistema MMPs/TIMPs é fortemente correlacionado com a expressão de alguns genes, tais como o gene Basigin (BSG), que induz a expressão de MMPs durante o ciclo ovariano em ratos (Smedts et al., 2005), ou o gene SPARC, que modula a expressão do TGF-β, fator de crescimento este associado ao aumento da agressividade tumoral (Podhajcer et al., 2008). A expressão do gene RECK foi descrita em diversos processos de remodelamento tecidual fisiológicos. Porém, uma diminuição em sua expressão, juntamente com o aumento na expressão das MMPs, tem sido associada com tumores mais agressivos e metastáticos (Meng et al., 2008). No entanto, apesar de RECK e SPARC estarem amplamente associados com remodelamento tecidual em diversas patologias, ainda não foi descrita a associação destes com remodelamento tecidual promovido pelo sistema MMPs/TIMPs que ocorre naturalmente durante a dinâmica ovariana. Considerando este quadro, o trabalho aqui proposto tem por objetivo analisar a expressão gênica de algumas MMPs- (-2, -9, -13, -14 e -19), e alguns de seus inibidores (TIMPs -1, -2, e -3 e RECK) e correlacioná-la com a expressão de SPARC e BSG durante a foliculogênese ovariana de ratas...

Estudo da fotoisomerização em filmes de polímero triacrilato dopado com azocorante disperse red 1

Triacrylate resins are widely used to fabricate 3D microstructures, photonic crystals and optical devices. These resins can be doped with photosensitive materials like Disperse Red 1 (DR1), an Azo dye that changes its molecular configuration from trans to cis (photoisomerisation) with variations in their optical absorption spectrum when irradiated with ultraviolet or visible light. The reversibility of this process is thermally activated and occurs when the molecule remains at dark. In this work was prepared a 1:1 mixture of ethoxylated-6-trimethylolpropane (SR499) and tris-2-hydroxyethyl-isocyanurate (SR368) triacrylate resins, plus photoinitiator Lucirin TPOL, forming a UV curable polymeric matrix doped with DR1. Thin films were deposited onto glass slides by spin-coating technique. The films showed photochromic effect when illuminated with a low power diode laser (450 nm and 50mW/cm2). This effect is reversible after sample is left in dark. Thermochromic effect was evaluated by optical absorption measurements in the range of 40 to 140oC, heating the samples in-situ

Preparação e caracterização da casca de banana prata particulada para aplicação com reforço em compósito de matriz de PEAD

The waste, exaggerated and incorrect disposal of biomass are common practices in modern times where everything is disposable. However the growing concern with the nature and the environment compel man to give nobler destinations for these products through sustainability and recycling of waste. Banana peel is a residual biomass, which is not consumed. It generates tons of waste per week in São Paulo city. This trash is disposed in dumps and landfills, which could be reduced by using it as reinforcement in natural composites. The high density polyethylene (HDPE) is a polymer derived from the ethylene polymerization and is easily recycled. Which makes it a sustainable material. In the present work characteristics of the natural composite composed with banana peel and high-density polyethylene were studied. It was noted that removing the lignin present in the banana peel, the fiber introduces a significant improvement in thermal resistance. The preparation of composite was made with a ratio of 5% and 10% of reinforcement in comparison with polymeric matrix mass. Composites were thermally, mechanically and microscopically characterized. The addition of fiber in the polymer increased the mechanical strength of the composite. The fiber surface treatment with distilled water removed the amorphous material present in the fibers, improving significantly thermal stability and increasing crystallinity of the celullose. The addition of 5% fiber in mass to the polymer increased significantly the tensile strength and elasticity modulus for the composite. With 10% of fiber addiction there were also an improvement when compared with pure HDPE, but when compared with 5% composite the mechanical properties are slightly lower. This may be due to the fiber particle size, which are small and eventually become a hub of tension ... (Complete abstract click electronic access below)

Propostas e rumos do desenvolvimento econômico brasileiro: novo modelo de desenvolvimento econômico e nova matriz macroeconômica

The main goal of this monograph is to understand the questions regarding brazillian economic development during the last thirty years. Through a historic deductive method, like simple techniques of descriptive statistics, we explicit the evolution process in which brazil has taken part in this last years. However, recently, by choosing non-conventional paths, represented basically by some aspects of the heterodox theory, the conservation of this process showed itself faulty. The defense for a return of the traditional ways employed in political economy just like in strategies of development are essential for the a continuous improvement of the brazillian population' life conditions

Viabilidade da geração de eletricidade a partir de fonte eólica on-shore: dificuldades e vantagens de expansão na matriz elétrica brasileira

The renewable energy sources presents an important role on the world's current context, its growing is essentially connected to the environmental issues and the energetic security, guided by the search for alternatives of energy. Among the alternative energy sources, the wind energy shows great importance in the brazilian territory, it has a great potential still unexplored and constant growth in the national electric matrix. The specific factor of generation, the conjuncture and the incentive politics influence on the expansion of wind energy in Brazil. Thus, the brazilian wind sector shows features which can be evaluated enable its developing. Keeping that in mind, the present work aims identify which are the advantages and the difficulties for the expansion of this energy source in the brazilian electric matrix. For that, the work studies the different parameters: features of electric generation of the different energy sources, incentive politics, generation costs, CO2 emission, evolution of wind energy in Brazil, the brazilian wind potential, and the regime of complementarily hydro-wind

Os efeitos da matriz bioparental nos processos de adoção de crianças e adolescentes

This paper is the result of a homonymous scientific research, funded by CNPq-PIBIC where we understand the adoption process as a process of dissidence in relation to the bio-parental matrix. Founded on a heteronormative naturalization of human sexuality - which presupposes a continuum and naturalized organization among sex / gender / desire – this bioparental matrix sets the binary relation of distinction between the legitimate/illegitimate child as their origin or not arising from “blood ties”. Considering our experience in the Project developed at the Department of Clinical Psychology at UNESP, Assis, SP called “Ties of love: Adoption, Gender, Citizenship and Rights”, we prepared a content analysis - as proposed by Bardin (1977) -, of transcripts of psychological sessions that were made from 2005 to 2012 in the "Center for Research and Applied Psychology “Dra. Betti Katzenstein. Our general objective was to analyze the effects of the bioparental matrix and its impact on children/adolescents and their families as well as estimate the possibilities of escape to the subjection to this bioparental matrix. The results showed us several aspects that may be significant for understanding the discursive crossings related to the practice of adoption. It was observed that there is still a great ambivalence pervading this theme, revealing that there is a discrepancy between what we say and what we do in relation to practices of caring among the adopted children. On the one hand, it was noticed that relatives rationally seek to enhance the bonding of the “emotional ties”, but their practices and beliefs, are still supported in modes of subjectivation that prioritize the biological discourse. This fact reveals a strained and conflictive field that probably weaknesses those families seeking to prioritize the ties of affection. However, as can be seen in this study, it is comforting and motivating to realize the power of resistance of individuals to absolute truths that govern their ways of feeling, affiliating and/ or exert their parenting.

Avaliação e correlação da presença de endotoxinas e MMP-3, -8 e -9 em canais radiculares com necrose pulpar submetidos ao tratamento endodôntico - estudo in vivo

It is know that endotoxin and various matrix metalloproteinases (MMPs) are involved in the development of periapical lesions. The purpose of this study was to evaluate and correlate the presence of endotoxins and MMP- 3, MMP-8 and MMP-9 in root canals of teeth with necrotic pulp and periapical lesion before, during and after the biomechanical preparation (PBM) using a combination of different irrigations solutions and intracanal dressing. Thirty-three single-root teeth with a diagnosis of pulp necrosis and periapical lesion radiographically visible were selected. Immediately after the coronal opening was collected the first sample from the root canal content. Then, all canals were prepared (cervical and middle thirds) by oscillatory instruments (EndoEze) and irrigated by 2.5% NaOCl. After, a manual preparation was made for the apical third and the teeth were divided into three groups according to the irrigation protocol: G1) 2.5% NaOCl (4 manual files); G2) 2.5% NaOCl (2 manual files) + [Ca (OH)2 0.14%] (2 manual files) and G3) 2.5% NaOCl (2 manual files) + polymyxin B (2 manual files). After the PBM, the second sample was collected; then the third collect was performed after using EDTA final flush. The fourth sample was collected 14 days after placing the dressing [2% chlorhexidine gel + Ca(OH)2]. Quantification of endotoxins was performed by a kinetic chromogenic lysate from amoebocytes of Limulus (LAL) and quantification of MMPs by ELISA assay. The results were analyzed statistically by Kruskal-Wallis and Dunn's test (5%) and ordinal Spearman correlation. Presence of endotoxin was observed in 100% of cases and G3 showed the greatest reduction of endotoxins from the 1st to the 2nd samples (97%), being statistically similar to G2 (84.2%) and different from G1 (49.4%) (p<0.05). The intracanal dressing promoted a significant reduction of endotoxin, no difference among the groups. For...
