1. Assessment of serum endocan levels in patients with beta-thalassemia minor
SUMMARY OBJECTIVE: Beta-thalassemia minor is a blood disease caused by a hereditary decrease in beta-globin synthesis, frequently leading to hypochromic microcytic anemia. Formerly called endothelial cell-specific molecule 1, endocan is a proteoglycan released by vascular endothelial cells in many organs. Our aim was to investigate the relationship between

2. Proteomic analysis of the venom of the social wasp Apoica pallens (Hymenoptera: Vespidae)
ABSTRACT Wasps are a diverse group of insects that possess a sting apparatus associated with a venom gland, which is used for predation and colony defense. The biochemistry of Hymenoptera venom has been evaluated in relation to allergy and immunology, and proteomics has been shown to be a powerful tool for the identification of compounds with pharmacological

3. Alveolar distribution in french rolls made using taro mucilage
Resumo Os emulsionantes são responsáveis pela formação de uma massa que contribui para a retenção de glúten em alvéolos, o gás produzido por levedura, aumentando assim o volume e a suavidade do pão. Há indícios de que os hidrocoloides, como a mucosa de taro (Colocasia esculenta), podem apresentar características semelhantes às dos emulsionantes

4. Evaluation of the metabolism of glycosaminoglycans in patients with interstitial cystis
Introduction: Painful bladder syndrome/interstitial cystitis (PBS/IC) pathogenesis is not fully known, but evidence shows that glycosaminoglycans (GAG) of bladder urothelium can participate in its genesis. The loss of these compounds facilitates the contact of urine compounds with deeper portions of bladder wall triggering an inflammatory process. We invest

5. Avaliação do metabolismo de glicosaminoglicanos em pacientes portadores de cistite intersticial / Evaluation of the metabolism of glycosaminoglycans in patients with interstitial cystitis
Introduction: interstitial cystitis is a chronic disease of the lower urinary tract whose symptoms are: increased urinary frequency, nocturia, perineal or pelvic pain that worses with bladder filling and improves with urination. The pathogenesis is not fully known, but there is evidence that proteoglycans and glycosaminoglycans lining the bladder urothelium

6. Efeito do exercício resistido na cartilagem articular de modelo animal de osteoartrite
The aim of this study was to evaluate the effect of a strength exercise protocol on articular cartilage in animal model of osteoarthritis (OA). Thirty-six rats were divided in 6 groups: Control (C, n = 6), Osteoarthritis (OA, n = 6), Sham (S, n = 6), Control with exercise (E n = 6), Osteoarthritis with exercise (OAE, n = 6) and Sham with exercise (SE, n = 6)

7. The metabolic dynamics of cartilage explants over a long-term culture period
INTRODUCTION: Although previous studies have been performed on cartilage explant cultures, the generalized dynamics of cartilage metabolism after extraction from the host are still poorly understood due to differences in the experimental setups across studies, which in turn prevent building a complete picture. METHODS: In this study, we investigated the resp

8. Heparanase isoform expression and extracellular matrix remodeling in intervertebral disc degenerative disease
OBJECTIVE: To determine the molecules involved in extracellular matrix remodeling and to identify and quantify heparanase isoforms present in herniated and degenerative discs. INTRODUCTION: Heparanase is an endo-beta-glucuronidase that specifically acts upon the heparan sulfate chains of proteoglycans. However, heparanase expression in degenerative intervert

9. 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

10. Quantitative evaluation of experimental choroidal neovascularization by confocal scanning laser ophthalmoscopy: fluorescein angiogram parallels heparan sulfate proteoglycan expression
The objective of the present study was to develop a quantitative method to evaluate laser-induced choroidal neovascularization (CNV) in a rat model using Heidelberg Retina Angiograph 2 (HRA2) imaging. The expression of two heparan sulfate proteoglycans (HSPG) related to inflammation and angiogenesis was also investigated. CNV lesions were induced with argon

11. Resposta do condrócito, proteoglicana, colágeno e fibronectina da cartilagem articular, após aplicação de um protocolo de imobilização, alongamento e remobilização articular
A função da cartilagem articular é dependente do condrócito e dos componentes de sua matriz extracelular, que por sua vez, podem ser regulados por estímulos mecânicos. Assim, alterações no suporte de carga podem afetar sua composição ou sua estrutura e interferir na sua capacidade funcional de sustentar e distribuir cargas e minimizar os estresses

12. 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.
