  • Patent number: 8283463
    Abstract: A process for sterilizing a solution comprising hyaluronic acid. The process comprises providing an aqueous solution of hyaluronic acid with a weight average molecular weight from 0.6 MDa to 3.6 MDa, and the concentration of the hyaluronic acid is from 0.04% to 0.8% by weight. The aqueous solution also has an ionic strength equivalent to an aqueous concentration of sodium chloride from 3% to 30% by weight.

  • Patent number: 8283456
    Abstract: The present invention relates to triterpene glycoside saponin-derived adjuvants, syntheses thereof, intermediates thereto, and uses thereof. QS-7 is a potent immuno-adjuvant that is significantly less toxic than QS-21, a related saponin that is currently the favored adjuvant in anticancer and antiviral vaccines. Tedious isolation and purification protocols have hindered the clinical development of QS-7. A novel semi-synthetic method is provided wherein a hydrolyzed prosapogenin mixture is used to synthesize QS-7, QS-21, and related analogs, greatly facilitating access to QS-7 and QS-21 analogs for preclinical and clinical evaluation.

  • Patent number: 8252750
    Abstract: Intrauterine Fetal Growth Restriction (IUGR) is a very important clinical problem for which no satisfactory treatment is available so far. The current invention of intravenous (IV) hypertonic glucose supplementation to the mother to improve the glucose transfer to the fetus at the intervillous space by improved facilitated diffusion can be a safe and easy way of treating this problem, as the improved fetal blood glucose can lead to fetal lipogenesis that can conserve the fetal O2 (oxygen) utilization and also relieve the associated metabolic derangements of fetal hypoxia, hypercapnia, and acidosis, apart from replenishing the oxidized coenzymes needed for the carbohydrate metabolism. The use of trans-amniotic fetal feeding studied by animal experiments can be difficult in humans, because of the danger of infection, which can be overcome by the use of implantable ports with a sterile patch technique.
