1. Efeitos do fator de crescimento e diferenciaÃÃo-9 e do hormÃnio folÃculo estimulante sobre o desenvolvimento in vitro de folÃculos prÃ-antrais bovinos. / Follicle isolated analyzed by fluorescence microscope (A, B) Preantral follicle cultured for 12 days in MEM (C, D) Preantral follicle cultured for 12 days in GDF-9 (E, F) Follicle preantral cultured for 12 days in GDF + FSH (G, H) Preantral follicles cultured for 12 days in FSH. Scale bar represents 50 micrometers
O objetivo deste estudo foi determinar o papel do GDF-9 sozinho ou em combinaÃÃo com FSH sobre a viabilidade, crescimento e expressÃo do RNAm para PCNA, HAS 1, HAS 2, versican e perlecan em folÃculos secundÃrios bovinos cultivados in vitro. Para estudos in vitro, folÃculos secundÃrios bovinos foram isolados e cultivados por doze dias, na presenÃa de

2. Mechanical evaluation of the resistance and elastance of post-burn scars after topical treatment with tretinoin
OBJECTIVE: After burn injuries, scarred skin lacks elasticity, especially in hypertrophic scars. Topical treatment with tretinoin can improve the appearance and quality of the skin (i.e., texture, distensibility, color, and hydration). The objective of this prospective study was to examine the effects of treatment with 0.05% tretinoin for one year on the bio

3. Noncrystalline uric acid inhibits proteoglycan and glycosaminoglycan synthesis in distal tubular epithelial cells (MDCK)
Hyperuricemia is associated with renal stones, not only consisting of uric acid (UrAc) but also of calcium oxalate (CaOx). Glycosaminoglycans (GAGs) are well-known inhibitors of growth and aggregation of CaOx crystals. We analyzed the effect of noncrystalline UrAc on GAG synthesis in tubular distal cells. MDCK (Madin-Darby canine kidney) cells were exposed t

4. Caracterização molecular das fases de separação, relaxamento e remodelação da sínfise púbica do camundongo, durante a prenhez, parto e pós-parto / Molecular characterization of separation, relaxation and remodeling of the mouse pubic symphysis during pregnancy, partum and postpartum
A remodelação que a sínfise púbica (SP) sofre durante a prenhez, parto e pós-parto é um dos eventos importantes para o parto normal, e ocorre no trato reprodutor feminino como útero, cérvice uterina e sínfise púbica em alguns mamíferos. Durante a prenhez de alguns roedores ocorre um acentuado processo de remodelação da sínfise púbica (SP). No

5. Proteoglicanos de estroma mamário e fibroadenoma humanos em diferentes condições hormonais. / Proteoglycans of human mammary stroma and fibroadenoma under different hormonal conditions.
Proteoglycans are important component of the extracellular matrix, which are involved in its organization and function, as well as in many biological processes. The aim of the present study was to investigate the changes that occur in proteoglycans of human fibroadenoma in comparison to proteoglycans of human normal breast tissue during the menstrual cycle.

6. Estudo histológico da matriz extracelular do músculo cricofaríngeo em cadáveres de diferentes idades / Histological study of extracellular matrix of cricopharyngeus muscle in different ages
O músculo cricofaríngeo desempenha um importante papel na deglutição. Acredita-se que seu comportamento elástico seja dependente não apenas do componente muscular, mas também do tecido conectivo intramuscular. O objetivo desse estudo foi analisar a presença e a distribuição do colágeno total, colágenos tipo I e III, fibras elásticas, fibronectin

7. Componentes da matriz extracelular e seus reguladores no músculo liso brônquico na asma / Extracellular matrix components and regulators in the airway smooth muscle in asthma
There is an intimate relationship between the extracellular matrix (ECM) and smooth muscle cells within the airways. Few studies have comprehensively assessed the composition of different ECM components and its regulators within the airway smooth muscle (ASM) in asthma. With the aid of image analysis, the fractional area of total collagen and elastic fibres

8. Extracellular matrix of the lateral pharyngeal wall in obstructive sleep apnea syndrome / Avaliação do papel da matriz extracelular na musculatura da parede lateral da faringe na fisiopatologia da síndrome da apnéia obstrutiva do sono
The lateral muscular pharyngeal wall appears to be the predominant structure involved in the collapse of the pharynx in obstructive sleep apnea (OSA). OSA patients and snorers have a narrower pharynx which is more susceptible to collapse and is associated with muscle thickening in the lateral pharyngeal wall, largely formed by superior pharyngeal constrictor

9. Distribuição do colágeno tipo I, colágeno tipo III e versican na lâmina própria da prega vocal humana de fetos e adultos: método histoquímico e imunoistoquímico / Collagen type I, collagen type III and versican distribution within the lamina propria of fetal and adult human vocal fold : histochemical and immunohistochemical method
Extracellular matrix has an important rule in the vocal fold physiology and the knowledge about your components is necessary. Fewer studies about matrix extracellular and no studies about versican in fetuses, and the necessity to improve the knowledge about extracellular matrix components in adults group came us to the elaboration of this study that has the

10. Valva mitral de suinos : uma abordagem bioquimica emorfologica
The mitral valve is a complex connective tissue structure, constituted by collagenous proteins, non collagenous proteins and proteoglycans. Structurally the valve leaflets are composed of four main layers: auricularis, fibrosa, spongiosa and ventricularis. The fibrosa layer forms the structural core of the valve, while the spongiosa has an important role in

11. Distribution of versican and hyaluronan in the mouse uterus during decidualization
Preparation for embryo implantation requires extensive adaptation of the uterine microenvironment. This process consists of cell proliferation and cell differentiation resulting in the transformation of endometrial fibroblasts into a new type of cell called decidual cell. In the present study, we followed the space-time distribution of versican and hyalurona

12. The extracellular matrix in multiple sclerosis: an update
Extracellular matrix (ECM) molecules play important roles in the pathobiology of the major human central nervous system (CNS) inflammatory/demyelinating disease multiple sclerosis (MS). This mini-review highlights some recent work on CNS endothelial cell interactions with vascular basement membrane ECM as part of the cellular immune response, and roles for w
