13. Pharmacological characterization of venoms from three theraphosid spiders: Poecilotheria regalis, Ceratogyrus darlingi and Brachypelma epicureanum
Abstract Background Tarantulas (Theraphosidae) represent an important source of novel biologically active compounds that target a variety of ion channels and cell receptors in both insects and mammals. In this study, we evaluate and compare the pharmacological activity of venoms from three taxonomically different theraphos

14. Molecular cloning of a hyaluronidase from Bothrops pauloensis venom gland
Background Hyaluronate is one of the major components of extracellular matrix from vertebrates whose breakdown is catalyzed by the enzyme hyaluronidase. These enzymes are widely described in snake venoms, in which they facilitate the spreading of the main toxins in the victim’s body during the envenoming. Snake venoms also present some variants (hyaluron

15. In vitro screening and evaluation of antivenom phytochemicals from Azima tetracantha Lam. leaves against Bungarus caeruleus and Vipera russelli
Background : Snakebites are considered a neglected tropical disease that affects thousands of people worldwide. Although antivenom is the only treatment available, it is associated with several side effects. As an alternative, plants have been extensively studied in order to obtain an alternative treatment. In folk medicine, Azima tetracantha Lam. is usual

16. Purification and characterization of a hyaluronidase from venom of the spider Vitalius dubius (Araneae, Theraphosidae)
BackgroundVenom hyaluronidase (Hyase) contributes to the diffusion of venom from the inoculation site. In this work, we purified and characterized Hyase from the venom of Vitalius dubius (Araneae, Theraphosidae), a large theraphosid found in southeastern Brazil. Venom obtained by electrical stimulation of adult male and female V. dubius was initially fractio

17. The Cuban scorpion Rhopalurus junceus (Scorpiones, Buthidae): component variations in venom samples collected in different geographical areas
Backgound The venom of the Cuban scorpion Rhopalurus junceus is poorly study from the point of view of their components at molecular level and the functions associated. The purpose of this article was to conduct a proteomic analysis of venom components from scorpions collected in different geographical areas of the country. Results Venom from the blue scorp

18. 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

19. Caracterização funcional e estrutural da hialuronidase isolada da peçonha de serpente Crotalus durissus terrificus / Functional and structural characterization of hyaluronidase isolated from Crotalus durissus terrificus snake venom
Hialuronidases são responsáveis pela hidrólise de hialuronan, o principal componente da matriz intersticial. Estas enzimas são ubíquas nas peçonhas de serpentes, contudo suas concentrações e características podem variar entre as espécies. Embora estudos indiquem a presença de atividade hialuronidásica na peçonha de Crotalus durissus terrificus e

20. Articaína com hialuronidase em infiltração bucal em primeiro molar inferior / Articaine and hyaluronidase in buccal infiltration on inferior first molar
O índice de sucesso em anestesia infiltrativa em molar inferior é muito baixo, o que justifica a técnica de bloqueio do nervo alveolar inferior mesmo essa sendo mais dolorida. Recentes estudos demonstraram que a anestesia infiltrativa com articaína apresentou maior índice de sucesso do que com a lidocaína, porém, ainda não foi possível evitar falha

21. Uso de hialuronidase 75 UTR/ml concomitante à mepivacaína associada à epinefrina em bloqueio do nervo alveolar inferior: estudo hemodinâmico e eletrocardiográfico / Use of hyaluronidase 75 TRU/ml concomitantly with mepivacaine associated epinephrine and inferior alveolar nerve block: hemodynamic and electrocardiographic study
Dentre os adjuvantes para os anestésicos locais (AL), a enzima hialuronidase tem seu uso consagrado na anestesia oftalmológica como difusor do AL. É utilizada para melhorar a eficácia clínica e prolongar a anestesia como alternativa aos anestésicos locais de longa duração em pacientes com comprometimento sistêmico. Este estudo duplo-cego e controlad

22. Structural analysis of the phimotic prepuce in patients with failed topical treatment compared with untreated phimosis
ObjectivesTo evaluate histological alterations in prepuce of patients with phimosis submitted to topic treatment with betamethasone in association with hyaluronidase.Materials and MethodsWe studied sixty patients (mean age 4.5), presenting true phimosis and treated with a topical treatment with betamethasone cream (0.2%) + hyaluronidase. The parents of seven

23. Ocorrência das espécies de leveduras isoladas de sangue e cateter de pacientes internados em Hospital Público Infantil de São Paulo (período 2007 a 2010). / Yeasts species isolated from blood and catheter from patients admitted into Children\ s Public Hospital of São Paulo (period 2007 to 2010).
We investigated the occurrence of yeast species isolated in a public hospital. We researched the presence of C. dubliniensis and investigated the species within the complex Candida parapsilosis and studied this complex in relation to biofilm´s production. We also investigated the factors related to virulence and studied the sensibility profile by the \"Etes

24. Purificação e caracterização de hialuronidase da peçonha da caranguejeira Vitalius dubius (Araneae, Theraphosidae) / Purification and characterization of hyaluronidase from venom of the brazilian spider Vitalius dubius (Aranease, Theraphosidae)
A hialuronidase (Hyase) de peçonha contribui para a difusão da peçonha do local da inoculação. Neste trabalho, foi purificada e caracterizada a Hyase da peçonha da Vitalius dubius (Araneae, Theraphosidae), uma aranha caranguejeira encontrada no sudeste do Brasil. A peçonha obtida por estimulação elétrica de machos e fêmeas adultas foi fracionada p
