Hyaluronic acid (HA) is a multifunctional natural biopolymer. It mainly known for its use in esthetic medicine and cosmesis. Classical medical applications are also ophthalmology, orthopedics, dentistry, dermatology. The of HA various fields have been growing potentially the last decade. In this article, most recent developments reviewed.

The hyaluronic acid receptor for endocytosis Stabilin-2/HARE mediates systemic clearance of multiple glycosaminoglycans from the vascular and lymphatic circulations. In addition, recent in vitro studies indicate that Stab2 can participate in signal transduction by interacting with hyaluronic acid (HA), which results in Erk phosphorylation. However, it is not known whether Stab2 function or HA-S...

Materials Sodium form of hyaluronic acid (HA, MW, 10 kDa) was a gift of Kolon Life Science, Korea. EDC.HCl (99%) and N-Hydroxy succinimide (NHS, 99%) were purchased from Shanghai Medeep Co., Ltd. Monostearin (glycerol α-monostearate, GMS), Sodium deoxycholate (DOC) and fluorescein isothiocyanate (FITC) were purchased from Solarbio (Beijing, China). Doxorubicin hydrochloride (DOX) was supplied b...

Injectable hyaluronic acid (HA) derivatives are the most used reabsorbable dermal fillers for soft tissue augmentation today and their utilization is considered safe. We report a cutaneous granulomatous reaction that developed in a woman 5 weeks after the first treatment with a nonanimal HA derivative for the correction of facial wrinkling. We describe the clinicopathological findings and cours...

Background and Aims: Tissue engineering is a relatively novel field that has been intensely developing during recent years and has shown to be excessively promising when used for cartilage regeneration. Scaffolds represent important components for tissue engineering. Materials and Methods: The Poly Lactic-Co-Glycolic Acid (PLGA) impregnated with fibrin and hyaluronic acid (HA) produce hybrid s...

conclusions use of ha in an algorithm model, is an extra and valuable tool for assessing liver necro inflammatory injuries- in parallel with liver biopsy- but more comprehensive studies are needed to approve the use of ha as an appropriate clinical tool. results there are several scientific studies indicating ha as a biomarker for high score fibrosis and cirrhosis in various liver diseases alon...

conclusions the most effective enhancer for aha and ha were liquid paraffin and glycerol, respectively. the most effective surfactant for both aha and ha was tween 80. the effects of the enhancers were increased by prolonging the exposure time. results after 1.5 and 12 hours, the maximum permeated amount of aha were 89.8 and 342.5 mg, respectively, which related to the formulations with liquid ...

Layer-by-layer (LBL) self-assembly technique has been proved to be a highly effective method to immobilize the main components of the extracellular matrix such as collagen and hyaluronic acid on titanium-based implants and form a polyelectrolyte multilayer (PEM) film by electrostatic interaction. However, the formed PEM film is unstable in the physiological environment and affects the long-time...
