Glucosamine increases hyaluronic acid production in human osteoarthritic synovium explants

BACKGROUND Glucosamine (GlcN) used by patients with osteoarthritis was demonstrated to reduce pain, but the working mechanism is still not clear. Viscosupplementation with hyaluronic acid (HA) is also described to reduce pain in osteoarthritis. The synthesis of HA requires GlcN as one of its main building blocks. We therefore hypothesized that addition of GlcN might increase HA production by sy...

Concentration of hyaluronic acid in synovial fluid.

ISOHE (1) HAS DESCRIBED a color reaction produced by the addition of alcoholic carbazole to uronic acids previously heated in 87% sulfuric acid. The purpose of the present report is to apply a modification of this method to the determination of hyaluronic acid in synovial fluid. The concentration of mucin in synovial fluid has been determined by the turbidity of the mucin clot (2) or by the che...

Sperm concentration, hyaluronic acid-binding capacity, aneuploidy and persistent histones in testicular cancer.

STUDY QUESTION Are the quantitative and qualitative characteristics of semen samples of patients with testicular cancer (TC), prior to anticancer therapy, different from infertile oligozoospermic (IO) and normozoospermic (NZ) age-matched men? SUMMARY ANSWER Sperm concentration in TC patients was significantly decreased with no difference in estimated numerical chromosome aberrations and nucle...

In Vitro Study of Hyaluronic Acid Based Scaffolds and Its Effect on Cartilage Regeneration

Recently, it has been proven that cartilage healing is difficult. The most commonly used treatments are autogenously cartilage grafting and allogeneic bone grafting, but grafts cannot fully meet treatment goals because of source, price, safety, and other concerns. Thus, a combination of biological materials and tissue engineering technology has become a recent trend in studies. Among the studie...
