1. Characterization of Decellularized Human Pericardium for Tissue Engineering and Regenerative Medicine Applications
Resumo Fundameto: O enxerto de pericárdio pode ser usado em muitos procedimentos de correção cirúrgica. Uma das estratégias da engenharia tecidual é o processo de descelularização. No entanto, embora esse processo diminua a resposta imunogênica, a descelularização pode modificar tanto o comportamento como a composição da matriz extracelular nat

2. Elastin increases biofilm and extracellular matrix production of Aspergillus fumigatus
Abstract Aspergillus fumigatus is an opportunistic saprobe fungus that accounts for 90% of cases of pulmonary aspergillosis in immunosuppressed patients and is known for its angiotropism. When it reaches the respiratory tract, A. fumigatus interacts with structural components and blood vessels of the lungs, such as elastin. To understand the effect of this s

3. Histochemical and immunohistochemical differences between solitary oral fibroma and fibrous papule of the face
Abstract: Background: The morphological similarities between fibrous papules of the face and multiple sporadic oral fibromas were mentioned long ago and a relationship between them has been reported in the literature. Objective: The aim of this study was to evaluate the participation of mast cells, elastin and collagen in a series of oral fibromas and fibr

4. Prevalence of scoliosis in Williams-Beuren syndrome patients treated at a regional reference center
OBJECTIVE:This study assessed the prevalence of scoliosis and the patterns of scoliotic curves in patients with Williams-Beuren syndrome. Williams-Beuren syndrome is caused by a chromosome 7q11.23 deletion in a region containing 28 genes, with the gene encoding elastin situated approximately at the midpoint of the deletion. Mutation of the elastin gene leads

5. Structural changes of dilated pelvic ureters in adults
PURPOSE: To perform a quantitative assessment of different types of pelvic ureter tissues with chronic dilation in adults, using stereological methods. METHODS: We analyzed fragments of dilated pelvic ureters obtained from 6 patients aged between 35 and 67 years (mean, 46 years) who underwent ureteral reimplantation surgery for different reasons. The obstru

6. Avaliação de fármacos fotossensíveis derivados da cloro alumínio ftalocianina no tratamento da progressão tumoral em modelo de matriz tridimensional mista / Evaluation of photosensitizers aluminum chloride phthalocyanine derivatives in the treatment of tumor progression in three-dimensional matrix.
Wound healing process can be favored by Low Level Laser Therapy, with the collagen and elastin matrix a dermic substitute described as an appropriate system in tissue engineering and in tridimensional skin systems. With this purpose, a study was elaborated using the system nanoemulsion of aluminium-chloride phthalocyanine (ClAlPc) as photosensitizer in skin

7. Detecção da microdeleção 7q11.23 por MLPA® e estudo clínico dos pacientes com síndrome de Williams-Beuren / Detection of the microdeletion 7q11.23 by MLPA® and clinical study of patients with Williams-Beuren syndrome
INTRODUCTION: Williams-Beuren syndrome (WBS) is a genetic disorder caused by a microdeletion in 7q11.23 region. It is characterized by typical facial dysmorphisms, mental retardation, hipersociable behavior, congenital heart disease, mainly supravalvular aortic stenosis (SVAS), and other variable congenital malformations. METHODS: 65 patients (40 males, 25 f

8. Development of a rabbit's urethral sphincter deficiency animal model for anatomical-functional evaluation
OBJECTIVE: The aim of the study was to develop a new durable animal model (using rabbits) for anatomical-functional evaluation of urethral sphincter deficiency. MATERIALS AND METHODS: A total of 40 New Zealand male rabbits, weighting 2.500 kg to 3.100 kg, were evaluated to develop an incontinent animal model. Thirty-two animals underwent urethrolysis and 8 a

9. Characterization of human adipose-derived stem cells and expression of chondrogenic genes during induction of cartilage differentiation
OBJECTIVES: Understanding the changes in chondrogenic gene expression that are involved in the differentiation of human adipose-derived stem cells to chondrogenic cells is important prior to using this approach for cartilage repair. The aims of the study were to characterize human adipose-derived stem cells and to examine chondrogenic gene expression after o

10. Angiogenesis and experimental hepatic fibrosis
Angiogenesis is a basic change occurring during repair by granulation tissue. This process seems to precede fibrosis formation in most types of chronic liver disease. To examine its presence and significance in different types of hepatic insults, this paper sought to identify the presence, evolution and peculiarities of angiogenesis in the most common experi

11. Porcine skin as a source of biodegradable matrices: alkaline treatment and glutaraldehyde crosslinking
In this work, the modifications promoted by alkaline hydrolysis and glutaraldehyde (GA) crosslinking on type I collagen found in porcine skin have been studied. Collagen matrices were obtained from the alkaline hydrolysis of porcine skin, with subsequent GA crosslinking in different concentrations and reaction times. The elastin content determination showed

12. Fibras elásticas da parede abdominal anterior em pacientes com hérnia ventral / Elastic fibers from the anterior abdominal wall in patients with ventral hérnias
In the present study samples were collected from abdominal linea alba aponeurosis of 30 patients (15 males and 15 females) aged from twenty to sixty years [30-59], (Mean=44.9±SD=7.3), with hernia of the anterior abdominal wall to evaluate the immunohistochemistry expression and morphometry of the elastic fibers. Nine of the patients were submitted to surger
