1. Retinoic acid induces differentiation of cochlear neural progenitor cells into hair cells
Resumo Introdução: As células progenitoras da orelha interna têm potencial para diferenciação multidirecional. O ácido retinoico é uma condição importante para o desenvolvimento da orelha interna. O bloqueio da via de sinalização do ácido retinoico no órgão de Corti pode reduzir significativamente o número de células ciliadas. Portanto, acr

2. Isolamento e diferenciação das células-tronco da polpa dentária canina em células progenitoras neurais
RESUMO O objetivo deste estudo foi verificar a capacidade de diferenciação das células-tronco da polpa dentária canina em células progenitoras neurais bem como quantificar obtenção e viabilidade celular, durante três passagens em cultura. As células foram extraídas da polpa dentária de dois cadáveres caninos, com aproximadamente dez meses de idad

3. High genetic differentiation of grapevine rootstock varieties determined by molecular markers and artificial neural networks
ABSTRACT. The genetic differentiation of grapevine rootstock varieties was inferred by the Artificial Neural Network approach based on the Self-Organizing Map algorithm. A combination of RAPD and SSR molecular markers, yielding polymorphic informative loci, was used to determine the genetic characterization among the rootstock varieties 420-A, Schwarzmann, I

4. Desmoplastic melanoma: a rare variant with challenging diagnosis
Abstract: Desmoplastic melanoma, a distinct and uncommon variant, is characterized as an invasive lesion with proliferation of fusiform melanocytes in the dermis and subcutaneous tissue, associated with varying patterns of desmoplasia. Neurotropism and neural differentiation may occur. The clinical presentation is variable and nonspecific, easily confused wi

5. Amniotic membrane as a biological scaffold for dental pulp stem cell transplantation in ocular surface reconstruction
RESUMO Objetivos: Avaliar a capacidade das células-tronco imaturas da polpa do dente de leite que são células-tronco mesenquimais de origem da crista neural, de se diferenciarem no epitélio corneano para fins de transplante de córnea e engenharia de tecidos quando cultivadas em membrana amnióticas desepitelizadas. Métodos: Foram comparamos so imunof

6. SSR-based genetic analysis of sweet corn inbred lines using artificial neural networks
Abstract Studies on genetic diversity and population structure provide basic information at the molecular level, which is a key input for breeding programs of crop species. This study evaluated the genetic diversity of 12 elite lines of sweet corn, using 20 microsatellite markers. To determine the genetic differentiation among lines, we used an artificial ne

7. Breast cancer diagnosis based on mammary thermography and extreme learning machines
Abstract Introduction Breast cancer is the most common cancer in women and one of the major causes of death from cancer among female around the world. The early detection and treatment are the major way to healing. The use of mammary thermography in Mastology is increasing as a complementary imaging technique to early detect lesions. Its use as a screening

8. Fetal Cerebrospinal Fluid Promotes Proliferation and Neural Differentiation of Stromal Mesenchymal Stem Cells Derived from Bone Marrow
ABSTRACT Embryonic cerebrospinal fluid (E-CSF) contains many neurotrophic and growth factors, acts as a growth medium for cortical progenitors, and can modulate proliferation and differentiation of neural stem cells. Mesenchymal stem cells (MSCs) are multipotential stem cells that can differentiate into several types of mesenchymal cells as well as nonmesenc

9. Analysis of the histomorphologic profile of invasive cutaneous squamous cell carcinoma from 2002 to 2011 in a pathology laboratory in the region of Campos Gerais, Brazil
ABSTRACT Squamous cell carcinoma is the second most common type of malignant skin cancer. It is also quite aggressive. The increasing incidence of the disease can be altered given its connection with sun exposure. The aim of this study was to establish the clinical and histomorphological profile of squamous cell carcinoma in the region of Campos Gerais, Stat

10. Breast tumor classification in ultrasound images using support vector machines and neural networks
Abstract Introduction The use of tools for computer-aided diagnosis (CAD) has been proposed for detection and classification of breast cancer. Concerning breast cancer image diagnosing with ultrasound, some results found in literature show that morphological features perform better than texture features for lesions differentiation, and indicate that a reduc

11. Morphological development of Corydoras aff. paleatus (Siluriformes, Callichthyidae) and correlation with the emergence of motor and social behaviors
Here we examine major anatomical characteristics of Corydoras aff. paleatus (Jenyns, 1842) post-hatching development, in parallel with its neurobehavioral evolution. Eleutheroembryonic phase, 4.3-8.8 days post-fertilization (dpf); 4.3-6.4 mm standard length (SL) encompasses from hatching to transition to exogenous feeding. Protopterygiolarval phase (8.9-10.9

12. Estudo in vitro do potencial de diferenciação das células tronco imaturas da polpa dentária humana em neurônios retinais. / Study of in vitro differentiation of human immature dental pulp stem cells into retinal neurons cells.
A retina é composta por células neuronais especializadas, que quando danificadas são incapazes de se regenerar. CTIPD são uma promissória fonte para substituir o tecido lesado pois são capazes de se diferenciar em quase todos os tipos celulares. O objetivo do estudo é avaliar o potencial de diferenciação das CTIPD em neurônios retinais. As CTIPD fo
