1. New tools for cell reprogramming and conversion: Possible applications to livestock
Abstract Somatic cell nuclear transfer and iPS are both forms of radical cell reprogramming able to transform a fully differentiated cell type into a totipotent or pluripotent cell. Both processes, however, are hampered by low efficiency and, in the case of iPS, the application to livestock species is uncertain. Epigenetic manipulation has recently emerged a

2. Stem-cell therapy for hearing loss: are we there yet?
Resumo Introdução: Nos mamíferos, as células ciliadas e os neurônios auditivos não apresentam capacidade regenerativa. Assim, os danos a esses tipos celulares são permanentes e levam à perda auditiva. Contudo, como não há tratamento que restabeleça a função auditiva, as terapias regenerativas utilizando células-tronco representam uma alternati

3. Up-regulation of RIP1 and IPS-1 in chronic HBV infected patients
Abstract IPS-1 and RIP1 are the main downstream molecules of RIG1 and MDA5, as intracytoplasmic receptors, which are the main receptors involved in recognition of internal and external viral double-stranded RNA. In this project, mRNA levels of IPS-1 and RIP1 were investigated in the peripheral blood immune cells of chronic hepatitis B (CHB) patients. IPS-1 a

4. Reprogramação de células mesenquimais de tecido adiposo em células-tronco pluripotentes por meio de proteína de fusão TAT / Nuclear reprogramming of adipose-tissue mesenchymal stem cells into pluripotent stem cells using TAT fusion protein
Os vírus são eficazes na transferência de genes em células devido aos seus mecanismos especializados. No entanto, vírus como veículos de entrega de genes podem acarretar em problemas, particularmente quando proposto para reprogramar células somáticas em células-tronco pluripotentes induzidas (iPS) visando utilização terapêutica. No presente estud

5. Mesenchymal stem cells in the dental tissues: perspectives for tissue regeneration
Nos últimos anos, as pesquisas com células tronco têm aumentado exponencialmente devido ao reconhecimento de que seu potencial terapêutico pode melhorar a qualidade de vida de pacientes com diversas doenças, como a doença de Alzheimer, isquemias cardíacas e, até mesmo, nas pesquisas de medicina regenerativa que visa uma possível substituição de ó

6. Implementação física de arquiteturas de hardware para a decodificação de vídeo digital segundo o padrão H.264/AVC / Physical implementation of hardware architectures for video decoding according to the H.264/AVC standard
Recentemente, o Brasil adotou o padrão SBTVD (Sistema Brasileiro de TV Digital) para transmissão de TV digital. Este utiliza o CODEC (codificador e decodificador) de vídeo H.264/AVC, que é considerado o estado-da-arte no contexto de compressão de vídeo digital. Esta transição para o SBTVD requer o desenvolvimento de tecnologia para transmissão, rece

7. InvestigaÃÃo da genotoxidade de larvicidas biolÃgicos e sintÃticos utilizados para controle de Aedes aegypti
Lately, the dengue fever has been considered the most important arbovirus affecting human kind. The aggravation of this epidemiologic situation has caused an expressive increase in the use of organofosforate insecticides in the combat of the vector, mainly temephos, which is widely and systematically applied in urban environmentsâ water reservoirs, even for

8. Genotipagem e perfil de resistência aos antiretrovirais do virus da imunodeficiência tipo 1 em população com falha terapeutica no Ceará, Brasil - 2002 a 2004 / Genotyping and antiretroviral resistance profile test from HIV-1 samples in patients with therapeutic failure from Ceará
Introduction: Genotypic testing for HIV-1 drug resistance is useful for selecting antiretroviral drugs for patients developing treatment failure. O melhor entendimento da sua interpretação facilitará sua utilização como ferramenta médica na terapêutica do HIV. The optimal understanding of its interpretation will give an important tool for HIV treatmen

9. Investigation of a novel Bacillus thuringiensis toxin
The aim of the present work was to investigate the toxicity, biochemical characteristics, gene and protein contents, and the mechanism of action of toxins from the Brazilian Bacillus thuringiensis (Bt) strain S725. This strain has been reported as toxic against the cotton boll weevil (Anthonomus grandis), a severe pest of cotton crops in America, which is co

10. Histopathological and ultrastructural effects of delta-endotoxins of Bacillus thuringiensis serovar israelensis in the midgut of Simulium pertinax larvae (Diptera, Simuliidae)
The bacterium Bacillus thuringiensis (Bt) produces parasporal crystals containing delta-endotoxins responsible for selective insecticidal activity on larvae. Upon ingestion, these crystals are solubilized in the midgut lumen and converted into active toxins that bind to receptors present on the microvilli causing serious damage to the epithelial columnar cel

11. Generation of Induced Pluripotent Stem Cell Lines from Tibetan Miniature Pig*
Induced pluripotent stem cell (iPS) technology appears to be a general strategy to generate pluripotent stem cells from any given mammalian species. So far, iPS cells have been reported for mouse, human, rat, and monkey. These four species have also established embryonic stem cell (ESC) lines that serve as the gold standard for pluripotency comparisons. Atte

12. Epigenetic reprogramming and induced pluripotency
The cloning of animals from adult cells has demonstrated that the developmental state of adult cells can be reprogrammed into that of embryonic cells by uncharacterized factors within the oocyte. More recently, transcription factors have been identified that can induce pluripotency in somatic cells without the use of oocytes, generating induced pluripotent s
