1. Short-term renal and metabolic effects of low dose vildagliptin treatment added-on insulin therapy in non-proteinuric patients with type 2 diabetes: open-label randomized prospective study
ABSTRACT Objective The aim of this randomized comparative study was to assess renal and metabolic effects of vildagliptin in insulin-treated type 2 diabetes (T2DM) patients without overt chronic kidney disease. Subjects and methods We randomized 47 insulin-treated non-proteinuric patients with satisfactory controlled T2DM and estimated glomerular filtratio

2. Anti-collagen type v: a marker of early systemic sclerosis?
Abstract Objective: To evaluate the frequency of anti-collagen type V in humans with early systemic sclerosis (SSc) compared to defined SSc patients and healthy controls, since collagen type V was shown to be overexpressed in early SSc patients’ skin and there is no data concerning the presence of this antibody in early stages of human SSc. Experimental s

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. Effect of hydroxyurea (HU) on gelatinization mechanism of type I collagen suspensions
ABSTRACT Mutant hemoglobins thermodynamic phase transitions (HbS, HbC, etc.) have been the causes of serious hemoglobinopathies that have been affecting mankind since the dawn of human race. HbS polymerization is the best known of these transitions and the original cause of sickle cell anemia. Hydroxyurea (HU, NH2CONHOH) is widely used as the main drug admin

5. Morphological changes in rat rectus abdominis muscle induced by diabetes and pregnancy
The urethral muscle of diabetic pregnant rats is affected by long-term mild diabetes and short-term severe diabetes, which plays a crucial role in the pathogenesis of pelvic floor disorders. We hypothesized that muscles outside the pelvis are subject to similar changes. The current study aimed at analyzing the effects of long-term mild and short-term severe

6. Experimental use of a cellulosic biopolymer as a new material for suburethral sling in the treatment of stress urinary incontinence
Purpose: To analyze the interaction between the cellulose exopolysaccharide (CEC) and urethral tissue when used as a pubovaginal sling. Materials and Methods: Forty Wistar rats were divided into four groups. In groups A and B the cellulose exopolysaccharide (CEC) was implanted around the urethral tissue (bladder neck below the upper margin) and the rats we

7. Unusual remodeling of the hyalinization band in vulval lichen sclerosus by type V collagen and ECM 1 protein
OBJECTIVES: The vulva is the primary site affected in lichen sclerosus, a chronic dermatosis in women that is histologically characterized by a zone of collagen remodeling in the superior dermis. The normal physiological properties of the vulva depend on the assembly of collagen types I (COLI), III (COLIII) and V (COLV), which form heterotypic fibers, and e

8. Modeling pulmonary fibrosis by abnormal expression of telomerase/apoptosis/collagen V in experimental usual interstitial pneumonia
Limitations on tissue proliferation capacity determined by telomerase/apoptosis balance have been implicated in pathogenesis of idiopathic pulmonary fibrosis. In addition, collagen V shows promise as an inductor of apoptosis. We evaluated the quantitative relationship between the telomerase/apoptosis index, collagen V synthesis, and epithelial/fibroblast rep

9. 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

Introdução: A imunização de coelhos saudáveis com colágeno do tipo V (COLV) reproduz as principais manifestações da esclerose sistêmica (ES), incluindo fibrose, vasculopatia e produção de autoanticorpos específicos da doença. Estudos preliminares mostraram que, tanto na derme de animais imunizados com COLV (COLV-IM), como na derme de pacientes c

11. Estudo da participação do colágeno V no câncer de pulmão, especificamente no carcinoma não de pequenas células / Study of the involvement of collagen V in lung cancer specifically in non-small cell carcinoma
O colágeno V vem emergindo como um potente indutor de morte celular (apoptose) via caspase. Nosso objetivo, neste estudo, foi examinar a interface entre o colágeno dos tipos I, III e V, apoptose tumoral e endotelial, angiogênese e células imunes, assim como o impacto desses fatores no prognóstico de pacientes com carcinomas não de pequenas células (CN

12. Produção recombinante e caracterização de uma desintegrina da peçonha de Rhinocerophis alternatus (antiga Bothrops alternatus) com atividade antimetastática visando o desenvolvimento de um novo fármaco
This work presents the study of the effects of an RGD disintegrin from Rhinocerophis alternatus (ancient Bothrops alternatus) in key steps of the metastatic cascade. Disintegrins are cysteine-rich peptides, which have several biological activities related to cell-cell interaction and cell adhesion. The correct pairing of disulfide bonds exposes the adhesive
