    • Chitosan in Mucoadhesive Drug Delivery: Focus on Local Vaginal Therapy 

      Andersen, Toril; Bleher, Stefan; Flaten, Gøril Eide; Tho, Ingunn; Mattsson, Sofia; Skalko-Basnet, Natasa (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-07)
      Mucoadhesive drug therapy destined for localized drug treatment is gaining increasing importance in today’s drug development. Chitosan, due to its known biodegradability, bioadhesiveness and excellent safety profile offers means to improve mucosal drug therapy. We have used chitosan as mucoadhesive polymer to develop liposomes able to ensure prolonged residence time at vaginal site. Two types of ...
    • Chitosan Lecithin Nanoparticles with New Chemical Entity. Antimicrobial Evaluation 

      Hemmingsen, Lisa Myrseth (Master thesis; Mastergradsoppgave, 2015-05-13)
      Chronic wounds are often colonized with biofilm-producing bacteria, such as Staphylococcus epidermidis, and these wounds often have high degree of complexity and are often challenging to treat. There is a high resistance to the traditional antimicrobial treatments and that is why these infections sometimes are persistent. Photodynamic therapy (PDT) is proposed as a potential solution to the problems ...
    • Chitosan Lecithin Nanoparticles with New Chemical Entity. Nanotoxicity Evaluation 

      Kangu, Lloyd Mbugua (Master thesis; Mastergradsoppgave, 2016-05-12)
      Chronic skin wounds are an exponentially increasing problem on a world basis, and are often hard to treat due to bacterial biofilm formation and resistance to different antibiotic treatments. Antimicrobial photodynamic therapy (aDPT) shows promise in resolving this issue, but clinical based treatments have yet to be established although photodynamic therapy is used for other conditions. A new ...
    • Chitosan-based delivery system enhances antimicrobial activity of chlorhexidine 

      Hemmingsen, Lisa Myrseth; Panchai, Pimmat; Julin, Kjersti; Basnet, Purusotam; Nystad, Mona; Johannessen, Mona; Skalko-Basnet, Natasa (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-29)
      Infected chronic skin wounds and other skin infections are increasingly putting pressure on the health care providers and patients. The pressure is especially concerning due to the rise of antimicrobial resistance and biofilm-producing bacteria that further impair treatment success. Therefore, innovative strategies for wound healing and bacterial eradication are urgently needed; utilization ...
    • Chitosan-based drug delivery system for a new chemical entity for photodynamic wound therapy 

      Hadafow, Muna Abukar (Master thesis; Mastergradsoppgave, 2014-05-24)
      Due to inappropriate or excessive use of antibiotics, multi resistance has become a global problem which threatens the public health. Photodynamic therapy has emerged as a promising and important approach in many fields of drug therapy. In recent years, many studies on photodynamic therapy for infections have shown promising results. One of the advantages of using PDT in treatment of infections is ...
    • Chitosan-Based Nanomedicine to Fight Genital Candida Infections: Chitosomes 

      Andersen, Toril; Mishchenko, Ekaterina; Flaten, Gøril Eide; Sollid, Johanna U Ericson; Mattsson, Sofia; Tho, Ingunn; Skalko-Basnet, Natasa (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-04)
      Vaginal infections are associated with high recurrence, which is often due to a lack of efficient treatment of complex vaginal infections comprised of several types of pathogens, especially fungi and bacteria. Chitosan, a mucoadhesive polymer with known antifungal effect, could offer a great improvement in vaginal therapy; the chitosan-based nanosystem could both provide antifungal effects and ...
    • Chitosan-coated liposomes for topical vaginal therapy: Assuring localized drug effect 

      Jøraholmen, May Wenche; Vanić, Željka; Tho, Ingunn; Škalko-Basnet, Nataša (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      The choice of drug therapy in pregnant patients suffering from vaginal infections is limited by the safety profile of the drug. Assuring the efficient topical therapy to avoid systemic absorption is considered the best therapy option. Chitosan-coated liposomes have been developed and optimized to assure localized therapy of clotrimazole. Chitosan was selected as mucoadhesive polymer both to prolong ...
    • Chitosan-modified liposomes for delivery of membrane-active antimicrobials – exploring the role of the polymer 

      Panchai, Pimmat (Master thesis; Mastergradsoppgave, 2022-05-12)
      Antimicrobial resistance in skin injury infections is becoming a rising problem as more conventional antimicrobials become ineffective in resistant infections. Therefore, developing novel effective antimicrobials while promoting wound healing is urgently needed. Membrane-active antimicrobials, such as antimicrobial peptides (AMPs), display promising antimicrobial activity, and could potentially solve ...
    • Chitosomes-In-Chitosan Hydrogel for Acute Skin Injuries: Prevention and Infection Control 

      Hemmingsen, Lisa Myrseth; Julin, Kjersti; Ahsan, Luqman; Basnet, Purusotam; Johannessen, Mona; Skalko-Basnet, Natasa (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-12)
      Burns and other skin injuries are growing concerns as well as challenges in an era of antimicrobial resistance. Novel treatment options to improve the prevention and eradication of infectious skin biofilm-producing pathogens, while enhancing wound healing, are urgently needed for the timely treatment of infection-prone injuries. Treatment of acute skin injuries requires tailoring of formulation to ...

    • Choice is not the issue. The misrepresentation of healthcare in bioethical discourse 

      Agledahl, Kari Milch; Førde, Reidun; Wifstad, Åge (Journal article; Tidsskriftartikkel; Peer reviewed, 2011-03-17)
      The principle of respect for autonomy has shaped much of the bioethics' discourse over the last 50 years, and is now most commonly used in the meaning of respecting autonomous choice. This is probably related to the influential concept of informed consent, which originated in research ethics and was soon also applied to the field of clinical medicine. But while available choices in medical research ...

      Nymo, Stig Haugset; Niyonzima, Nathalie; Espevik, Terje; Mollnes, Tom Eirik (Journal article; Tidsskriftartikkel, 2014-07-05)
      Cholesterol crystals are known to be a hallmark of atherosclerosis with recent studies demonstrating deposition of these crystals in early fatty streak formation as well as penetrating the intima following plaque rupture. Inflammation has also become a central focus in atheroma development and endothelial cell activation is recognized as necessary for the recruitment of inflammatory cells to the ...

      Blindheim, Line Grebstad (Master thesis; Mastergradsoppgave, 2016-05-02)
      Abstract Substance addiction is detrimental to the addict, their family, social environment and society as a whole, which is why research needs to approach it with problem solving in mind. The present study has a salutogenic health perspective, and focuses on coping in recovery from substance addiction. The informants’ experiences of coping were explored using the qualitative approach. The informants ...
    • Chromosomal microarray in prenatal diagnosis - replacing traditional karyotyping 

      Winther, Alise Marie (Master thesis; Mastergradsoppgave, 2019-06-02)
      Abstract Background: In prenatal diagnosis, chromosomal microarray analysis (CMA) has not yet fully replaced conventional karyotyping. As CMA is able to detect smaller genomic imbalances compared to conventional karyotyping, it has become the first-tier test in pregnancies with ultrasound abnormalities. Objectives/aims: The aim of the study was to learn about CMA and its appliance in invasive ...

      Nordheim, Espen; Jenssen, Trond Geir (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-29)
      Chronic kidney disease is a common complication and concomitant condition of diabetes mellitus. The treatment of patients with diabetes and chronic kidney disease, including intensive control of blood sugar and blood pressure, has been very similar for type 1 and type 2 diabetes patients. New therapeutic targets have shown promising results and may lead to more specific treatment options for patients ...
