1. Bullous pemphigoid and milia: prevalence and clinical laboratory findings in a Brazilian sample
Abstract Background: Bullous pemphigoid (BP) associated with milia lesions has been increasingly reported, but its prevalence has not been reported in a Brazilian BP population yet. Objectives: To describe the occurrence and clinical-laboratorial findings of BP-milia association in a southeastern Brazilian sample. Methods: A descriptive study based on the

2. Observation of the effect of bone marrow mesenchymal stem cell transplantation by different interventions on cirrhotic rats
Bone marrow mesenchymal stem cells (BMSCs) transplantation has attracted attention for the treatment of liver cirrhosis and end-stage liver diseases. Therefore, in this study, we evaluated the effect of different methods of BMSCs transplantation in the treatment of liver cirrhosis in rats. Seventy-two male Sprague-Dawley rats were divided into 7 groups: 10 w

3. Purification and enzymatic characterization of a novel metalloprotease from Lachesis muta rhombeata snake venom
Abstract Background: Lachesis muta rhombeata (Lmr) is the largest venomous snake in Latin America and its venom contains mainly enzymatic components, such as serine and metalloproteases, L-amino acid oxidase and phospholipases A2. Metalloproteases comprise a large group of zinc-dependent proteases that cleave basement membrane components such as fibronectin

4. Identification of the alpha-enolase P46 in the extracellular membrane vesicles of Bacteroides fragilis
BACKGROUND Members of the Bacteroides fragilis group are the most important components of the normal human gut microbiome, but are also major opportunistic pathogens that are responsible for significant mortality, especially in the case of bacteraemia and other severe infections, such as intra-abdominal abscesses. Up to now, several virulence factors have b

5. Effects of penicillin and erythromycin on adherence of invasive and noninvasive isolates of Streptococcus pyogenes to laminin
This study investigated the possible relationship between the invasiveness of group A Streptococcus (GAS) strains and their abilities to adhere to laminin and assessed the effects of subinhibitory concentrations of penicillin and erythromycin on the ability of GAS to adhere to laminin. The adherence of noninvasive and highly invasive isolates of GAS to lamin

6. Immobilization and therapeutic passive stretching generate thickening and increase the expression of laminin and dystrophin in skeletal muscle
Extracellular matrix and costamere proteins transmit the concentric, isometric, and eccentric forces produced by active muscle contraction. The expression of these proteins after application of passive tension stimuli to muscle remains unknown. This study investigated the expression of laminin and dystrophin in the soleus muscle of rats immobilized with the

7. Fibronectin modulates thymocyte-thymic epithelial cell interactions following Trypanosoma cruzi infection
Developing thymocytes interact with thymic epithelial cells (TECs) through cell-cell interactions, TEC-derived secretory moieties and extracellular matrix (ECM)-mediated interactions. These physiological interactions are crucial for normal thymocyte differentiation, but can be disrupted in pathological situations. Indeed, there is severe thymic atrophy in an

8. Análise de proteínas cuja expressão é controlada por miRNA e relacionada à progressão do adenocarcinoma de próstata por imuno-histoquimica em tissue microarray / Analysis of proteins whose expression is controlled by miRNA and related to the progression of prostate adenocarcinoma by immunohistochemistry on tissue microarray
Introdução: O Câncer de Próstata (CaP) é o tumor mais comum do homem e a segunda causa de óbito por câncer no Brasil. MicroRNA (miRNA) é uma classe de pequenos RNA regulatórios não codificantes de proteínas que tem papel fundamental no controle da expressão dos genes. São responsáveis pelo controle de processos fundamentais na célula e estão

9. Estudo de proteínas relacionadas ao costâmero em secções longitudinais de músculo sóleo de ratas imobilizadas e reabilitadas pelo alongamento passivo manual intermitente / Study of costameric proteins in soleus muscle longitudinal sections of female rats immobilized and rehabilitated by intermittent passive manual stretching
The interface between sarcolemma and extracellular matrix in skeletal muscle tissue is constituted by specialized proteins that are responsible for the transversal and longitudinal forces transmission to the myofiber. Skeletal muscle adaptations to physiological and pathological forces, such as segmental immobilization and rehabilitation exercises, may contr

10. Imunoproteção de ilhotas pancreáticas microencapsuladas em biomateriais inovadores e seu potencial terapêutico no diabetes mellitus tipo 1 / Immunoprotection of pancreatic islets microencapsulated in inovative biomaterials and its therapeutic potential in type 1 Diabetes Mellitus
Transplantation of microencapsulated islets represents an attractive therapeutical approach to treat type 1 Diabetes Mellitus, accounting for an improved glycemic control and the abolishment of immunosuppressive therapies. However, maintenance of long-term β-cell viability remains a major problem. During islet isolation, the loss of extracellular matrix

11. Mycobacterial laminin-binding histone-like protein mediates collagen-dependent cytoadherence
When grown in the presence of exogenous collagen I, Mycobacterium bovis BCG was shown to form clumps. Scanning electron microscopy examination of these clumps revealed the presence of collagen fibres cross-linking the bacilli. Since collagen is a major constituent of the eukaryotic extracellular matrices, we assayed BCG cytoadherence in the presence of exoge

12. Role of hyaluronic acid and laminin as serum markers for predicting significant fibrosis in patients with chronic hepatitis B
OBJECTIVES: The aim of this study was to evaluate the diagnostic performance of serum HA and LN as serum markers for predicting significant fibrosis in CHB patients. METHODS: Serum HA and LN levels of 87 patients with chronic hepatitis B and 19 blood donors were assayed by RIA. Liver fibrosis stages were determined according to the Metavir scoring-system. Th
