The management of nasal deformities especially after rhinoplasty is a challenge. Postsurgical edema may last 6-8 months, causing aesthetic irregularities and nose deformities. The aim of this study is to present the correction of minor nose deformities secondary to rhinoplasty using hyaluronic acid subdermal injections. Eleven patients were treated between 2009 and 2011 with subdermal injection...

A previously described method for determination of hyaluronic acid is modified for the analysis of pleural and ascitic fluids. After 20 microL of the acellular supernate is precipitated with ethanol, the precipitate is digested overnight with chondroitinases and chondroitin sulfatases. The content of hyaluronic acid-derived disaccharide is then analyzed by "high-performance" liquid chromatograp...

Adult human articular cartilage contains a hyaluronic acid-binding protein of Mr 60 000-75 000, which contains disulphide bonds essential for this interaction. The molecule can compete with proteoglycan subunits for binding sites on hyaluronic acid, and can also displace proteoglycan subunits from hyaluronic acid if their interaction is not stabilized by the presence of link proteins. The abund...

The common pathway leading to liver fibrosis and cirrhosis is growing deposition of extracellular matrix (ECM). It results from molecular and histological rearrangement of collagens, glycoproteins and hyaluronans. Hyaluronic acid is a chief component of the extracellular matrix of connective tissues and plays the main structural role in the formation of ECM. The most important organ involved in...

Recent analyses of tears indicate the presence of glycosaminoglycans as their components, but their origin remains unknown. To further understand the origin of these tear components, we investigated by immunohistochemical techniques the localization of glycosaminoglycans and CD44 human lacrimal glands obtained from 20 cadavers at autopsy. Monoclonal antibodies to CD44, a receptor for hyaluronic...

PURPOSE Dextranomer/hyaluronic acid implantation is associated with a granulomatous inflammatory reaction, replaced by fibrosis. Appearance of myofibroblasts is considered a crucial event in fibrosis, and CD68 positive cells and other factors are implied in their activation. Mast cells are a source of these factors and tryptase can induce fibroblast to express alpha-smooth muscle actin, which i...

BACKGROUND Nonanimal hyaluronic acid gel was recently developed for soft tissue augmentation and volume expansion and has been shown to offer several advantages in comparison to other augmentation materials. There are rare reports of adverse events believed to be secondary to trace amounts of proteins in the hyaluronic acid raw material. OBJECTIVE To determine the safety profile of nonanimal ...

UNLABELLED Group A streptococcus (GAS) causes human pharyngitis and invasive infections and frequently colonizes individuals asymptomatically. Many lines of evidence generated over decades have shown that the hyaluronic acid capsule is a major virulence factor contributing to these infections. While conducting a whole-genome analysis of the in vivo molecular genetic changes that occur in GAS du...

The main objective of this article is to demonstrate through experimental means the capacity of the quartz crystal resonator (QCR) to characterize biological samples of aqueous dilutions of hyaluronic acid according to their viscosity and how this capacity may be useful in the potential diagnosis of arthritic diseases. The synovial fluid is viscous due to the presence of hyaluronic acid, synthe...

Bacterial cellulose (BC) has become established as a remarkably versatile biomaterial and can be used in a wide variety of applied scientific applications, especially for medical devices. In this work, the bacterial cellulose fermentation process is modified by the addition of hyaluronic acid and gelatin (1% w/w) to the culture medium before the bacteria is inoculated. Hyaluronic acid and gelat...
