Mange av pasientskadene på sykehus er legemiddelrelaterte og mange innleggelser ... -
The development of electrospun chloramphenicol containing wound dressing
(Master thesis; Mastergradsoppgave, 2021-05-11)Wound healing is among the most complex processes in the human body that is greatly coordinated with a focus to rebuild tissue integrity and restore the skin´s protective barrier. The normal healing process is disrupted in chronic wounds, leading to delayed wound healing due to several underlying factors such as aging, obesity, and diabetes. Among chronic wounds 50 % are infected and up to 78 % of ... -
Zwitterionic antimicrobial nanoparticles for biofilm therapy
(Mastergradsoppgave; Master thesis, 2021-05-10)In recent years, many pathogenic bacteria have developed resistance against the existing antimicrobials, a phenomenon known as antimicrobial resistance (AMR). One of the many reasons contributing to the observed failure of current therapies, is the poor drug penetration across the microbial biofilm. Biofilms are small structural communities of bacterial cells that excrete an extracellular polymeric ... -
