• Fabrication of Composite Polyurethane/Hydroxyapatite Scaffolds Using Solvent-Casting Salt Leaching Technique

  Publikacja

  • J. Wosek

  - Advances in Materials Science - Rok 2015

  Scaffolds are porous three-dimensional structures which are used to fill bone losses and make them possible to cells to grow. Many different structural and biological properties are required from them: porosity, mechanical strength and biocompability. The present research is aimed at development of composite polyurethane/hydroxyapatite scaffolds by using the solvent-casting salt leaching method. The SEM examinations were applied...

  - Rok 2014

  In this study, the polyurethane (PU) system based on poly(ethylene-butylene) adipate diol, 1,6-hexamethylene diisocyanate, 1,4-butanediol and ascorbic acid is used to prepare a foamed material. Polymer foams were created using solvent casting/salt-particle leaching (SC/PL) method. The influence of the PU concentration in different solutions [either in a DMF or in DMF with THF as a co-solvent] on the morphology and porosity of the...

• Importance of Conjugation of the Bile Salt on the Mechanism of Lipolysis

  Publikacja

  • N. Łozińska
  • C. Jungnickel

  - MOLECULES - Rok 2021

  We aim to advance the discussion on the significance of the conjugation of bile salts (BS) in our organism. We hypothesize that conjugation influences the rate of lipolysis. Since the rate of lipolysis is a compound parameter, we compare the effect of conjugation on four surface parameters, which contribute to the rate. Since deconjugation is due to gut microbiota, we hypothesize that microbiota may affect the rate of lipolysis....

  W artykule opisano syntezę azobenzopochodnych pirolu oraz wpływ beta-cyklodekstryn (beta-CD) na te reakcje. W bezpośredniej reakcji prowadzonej bez udziału cyklodekstryny, otrzymano przede wszystkim związek będący monopodstawioną azopochodną pirolu. Przy użyciu większych ilości beta cyklodekstryny w reakcji, tzn. 1 i 2 milimole przypadające na 1 milimol pirolu, otrzymano, oprócz niewielkich ilości innych związków, przede wszystkim...
