13. Effects of the hyaluronic acid infiltration in the treatment of internal temporomandibular joint disorders
RESUMO JUSTIFICATIVA E OBJETIVOS: O protocolo primário de controle das disfunções temporomandibulares prioriza as medidas reversíveis e menos invasivas. Entretanto, o tratamento conservador mostra-se, algumas vezes, ineficaz, e como alternativa terapêutica, tem sido sugerido o uso de ácido hialurônico para com isso, verificar a sua efetividade em pac

14. Hyaluronic acid-coated nanoemulsions loaded with a hydrophobic ion pair of all-trans retinoic acid for improving the anticancer activity
All-trans retinoic acid (ATRA) has been studied for the treatment of cancer, including leukemia and breast cancer. This work aims to develop nanoemulsions (NE) loaded with a hydrophobic ion pair (HIP) of all-trans retinoic acid (ATRA) and a lipophilic amine, stearylamine (SA), and coated with hyaluronic acid (HA) to enhance anticancer activity and reducing t

15. Hyaluronic acid in tobacco-exposed rats. Inflammatory reaction, and duration of effect
Abstract Purpose: To evaluate the hyaluronic acid (HA) inflammatory reaction, fibroblasts, fibrosis and duration of effect in the dorsal region of tobacco-exposed rats. Methods: Ten Wistar rats were divided into two groups: tobacco-exposed-group (TEG;n=5) and air-control-group (CG;n=5). The TEG animals were tobacco-exposed twice a day, 30-minutes/session,

16. Hyaluronic acid accelerates bone repair in human dental sockets: a randomized triple-blind clinical trial
Abstract This study evaluated the effects of hyaluronic acid (HA) on bone repair of human dental sockets. Thirty-two lower first premolars were extracted from 16 patients (2 per patient) for orthodontic reasons. Following the extractions, one socket was randomly filled with 1% HA gel, while the other was allowed to naturally fill with blood clot. After 30 an

17. Hyaluronic acid in dermatomyositis and polymyositis: relationship with disease and cutaneous lesions
Abstract: Background: There are scarce studies in the literature about hyaluronic acid in systemic autoimmune myopathies. Objectives: To analyze the serum level of hyaluronic acid in patients with dermatomyositis and polymyositis. Methods: Cross-sectional study, single-center, that evaluated hyaluronic acid in 18 dermatomyositis and 15 polymyositis (Bohan

18. To what extent does hyaluronic acid affect healing of xenografts? A histomorphometric study in a rabbit model
ABSTRACT Among the many graft materials that have been used for the treatment of bone defects in oral and maxillofacial regions is xenograft. To improve osteoconductive effects of xenografts, they have been combined with various biocompatible materials, such as hyaluronic acid and bone morphogenetic protein. Objective: To determine bone-healing capacity of

19. Effects of hyaluronic acid on bleeding following third molar extraction
Abstract Objective To explore the effects of hyaluronic acid (HA) on bleeding and associated outcomes after third molar extraction. Methods Forty patients who had undergone molar extraction were randomly divided into two groups; 0.8% (w/v) HA was applied to the HA group (n=20) whereas a control group (n=20) was not treated. Salivary and gingival tissue f

20. Development and characterization of hyaluronic acid-lysine nanoparticles with potential as innovative dermal filling
ABSTRACT Skin aging causes changes such as wrinkles and flaccidity leading to a large demand for aesthetic procedures, including dermal filling. A key agent in dermal filling is hyaluronic acid (HA), which is a naturally occurring glycosaminoglycan. However, it is a hydrophilic macromolecule that experiences great difficulty in crossing the skin barrier caus

21. Residual Hearing Preservation with the Evo® Cochlear Implant Electrode Array: Preliminary Results
Abstract Introduction The preservation of residual hearing is currently an important challenge for cochlear implant surgeries. Indeed, if patients exhibit functional hearing after cochlear implantation, they can benefit from the combination of acoustical stimulation, usually in the low-frequencies and electrical stimulation in the high-frequencies. This co

22. Acral papular mucinosis: a new case of this rare entity
Abstract Acral persistent papular mucinosis (APPM) is a rare subtype of localized lichen myxedematosus. It consists of small papules localized exclusively on the back of the hands, wrists and extensor aspects of distal forearms with no other clinical or laboratory manifestations. The lesions tend to persist and may increase slowly in number. Histologically,

23. Expression of heparanase in basal cell carcinoma and squamous cell carcinoma
Abstract: Background: Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Objectives: Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established

24. The outcomes of two different bulking agents (dextranomer hyaluronic acid copolymer and polyacrylate-polyalcohol copolymer) in the treatment of primary vesico-ureteral reflux
ABSTRACT Purpose Subureteral injection of bulking agents in the endoscopic treatment of vesicoureteral reflux is widely accepted therapy with high success rates. Although the grade of vesicoureteric reflux and experience of surgeon is the mainstay of this success, the characteristics of augmenting substances may have an effect particularly in the long term
