OBJECTIVES The matrix protein hyaluronic acid (HA, hyaluronan) has possibly additional immune-regulatory functions in inflammation. We aimed at evaluating serum HA concentrations in critically ill patients. DESIGN AND METHODS We analyzed serum HA levels in 164 critically ill patients at a medical ICU and 61 healthy controls, with respect to organ dysfunction, systemic inflammation and mortali...
Purpose: The best sperm selection by its binding ability to hyaluronic acid for ICSI and assessment of correlation between sperm binding ability to hyaluronic acid with sperm parameters, protamine deficiency and DNA fragmentation. Materials and Methods: Semen samples collected from 55 infertile couples referring to ?? Fertility and Infertility center were collected during this study. Semen ana...
Abstract Background: Knee osteoarthritis (KOA) is one of the most common diseases in the world that not only has surgical treatment, but also numerous medical drug treatments. The object of this study is to assess the effect of two medical treatments with use of mixture of oxygen-ozone and hyaluronic acid on pain and disability of patients with KOA. Materials and methods: In a randomized clinic...
OBJECTIVE Viscosupplementation with hyaluronic acid (HA) or its derivatives for the symptomatic relief of osteoarthritis (OA) of the hip joint has never been studied in placebo-controlled, double-blinded trials and conflicting results have been obtained from the published open trials. The aim of this study was to review the literature on viscosupplementation as a symptomatic treatment of hip OA...
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 ...
Gelatin, chitosan and hyaluronic acid are natural components used to prepare polymeric scaffold in tissue engineering. The physical properties of these materials confer an appropriate microenvironment for cells, which can be used as a regeneration system for skin and cartilage. In this work, we prepared and characterized a Gelatin/Chitosan/Hyaluronan lyophilized-polymer. Physical properties of ...
The membranous labyrinth of the inner ear, with its three semicircular canals, originates from a simple spheroidal otic vesicle. The process is easily observed in Xenopus. The vesicle develops three dorsal outpocketings; from the two opposite faces of each outpocketing pillars of tissue are protruded into the lumen; and these paired 'axial protrusions' eventually meet and fuse, to form a column...
AIMS/BACKGROUND The aim of this study was to assess quantitatively the effectiveness of hyaluronan on corneal disruption in patients with dry eye. Corneal epithelial barrier function was evaluated by measuring fluorescein permeability using a slit-lamp fluorophotometer. METHODS 11 patients with dry eye were assigned to this study. Hyaluronan ophthalmic solution (0.1% hyaluronic acid) was inst...
