    • The effect of β-lactamase evolution on biofilm formation in Vibrio cholerae 

      Haukefer, Anne Sofie Bernhardsen (Master thesis; Mastergradsoppgave, 2023-05-15)
      Antimicrobial resistance (AMR) has emerged as one of the greatest threats to public health in the 21st century. Especially, the production of -lactamase enzymes has become the leading cause of -lactam resistance in Gram-negative pathogens. In addition, many of the pathogens associated with extensive antimicrobial resistance form biofilms, which further increases their persistence. Studies from ...
    • Kvalitet av legemiddelbruk og legemiddelinformasjon hos hoftebruddspasienter ved Sykehuset i Vestfold HF – en tverrsnittstudie 

      Nguyen, Caroline Thy (Master thesis; Mastergradsoppgave, 2019-05-15)
      Det er i hovedsak eldre personer som gjennomgår hoftebrudd, som er et fryktet osteoporotisk brudd. Eldre har flere sykdommer som fører til at de blir behandlet med flere legemidler sammenlignet med yngre. Dette vil igjen øke risikoen for uhensiktsmessig legemiddelbruk. I tillegg overføres eldre hyppig inn og ut og mellom helseinstitusjoner, som skaper et behov for velfungerende informasjonsoverføring. ...
    • Dual delivery of chlorogenic acid and mimic of antimicrobial peptide – towards wound treatment 

      Salamonsen, Mari (Master thesis; Mastergradsoppgave, 2022-05-12)
      Chronic wounds are a major burden, causing both morbidity and mortality in patients, as well as a massive economical strain on health care systems worldwide. These wounds have a high degree of complexity and are often difficult to treat due to the many factors limiting healing, such as inflammation, biofilm formation and bacterial infections. With these typically persistent infections and a rising ...
    • 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 ...

    • Process optimization of albumin-stabilized mitotane nanoparticle preparation by dual centrifugation and first lyophilization study 

      Zhang, Cindy Jia Ru (Mastergradsoppgave; Master thesis, 2022-05-13)
      Albumin-stabilized mitotane nanoparticles intended for intravenous application can serve as a potential formulation for the treatment of adrenocortical carcinoma. However, the particle size of a nanoparticle-based formulation is crucial for the in vivo behavior of the nanoparticles following an intravenous injection. Prior to this project, the particle size of this nanoformulation had a mean of ...
    • Push and pull factors for migration of foreign pharmacists to Norway 

      Iqbal, Saleem (Mastergradsoppgave; Master thesis, 2022-05-12)
      Migration of foreign pharmacists to Norway has increased considerably in recent years. Data from the Directorate of Health shows that 1592 foreign pharmacists received authorization in Norway from 2013 to 2021 as compared to 1952 Norwegian pharmacists. There are several theories of migration, but “push and pull theory” is the most widely used approach to learn about reasons of migration. According ...
    • Computational studies on the human GnRH-I and the GnRH-receptor 

      Tran, Anton (Mastergradsoppgave; Master thesis, 2022-05-12)
      Gonadotropin-releasing hormone receptor (GnRH-R), which is a Class A G-protein coupled receptor (GPCR), has a vital role in the regulation of sex hormones. The receptor also has a prominent role in diseases, with examples being reproductive cancers and non-reproductive cancers like glioblastoma. Gonadotropin-releasing hormone (GnRH) agonists have been proven to combat cell proliferation in cancers. ...
    • The productivity gain by preventing first and subsequent hip fractures in osteoporotic patients as a result of optimal treatment 

      Aamodt, Martin Arvin (Mastergradsoppgave; Master thesis, 2022-05-11)
      Background: Preventing hip fractures could prevent patient disability and premature death, and lead to substantial societal savings in terms of productivity gains. However, the Norwegian government has decided against emphasizing productivity gains in prioritization decisions for financing pharmaceutical drugs. The question, however, remains whether including productivity gains could lead to better ...
    • Medicine articles on English Wikipedia: Quantifying the presence of pharmaceutical industry edits and analyzing their content. 

      Jadgal, Asia (Mastergradsoppgave; Master thesis, 2022-05-11)
      Today, Wikipedia has developed into a prominent source for health queries to the vast public. Over the years, some studies have been performed to understand what the webpage can and cannot offer. However, the current literature lacks knowledge of how the pharmaceutical industry is present in Wikipedia’s medicine articles. The immediate objective of this research was to quantify the presence of ...
    • Development of DNA Nanoparticles with Properties for Enhanced Biofilm Uptake 

      Borøy, Vegard (Mastergradsoppgave; Master thesis, 2022-05-11)
      Microbial biofilms account for up to 80% of all bacterial infections. They are described as small structural communities of bacteria which are embedded in a self-produced extracellular (EPS) matrix. This EPS matrix poses a substantial challenge for antimicrobial treatment by hindering traversal of antimicrobial agents. Nanotechnology based drug delivery systems (DDS) offer a promising solution ...
    • Elevating Safe Use of Over-The-Counter Medications in Older Adults: A Narrative Review of Pharmacy Involved Interventions and Recommendations for Improvement 

      Lehnbom, Elin; Berbakov, Maria E.; Hoffins, Emily L.; Moon, Jukrin; Welch, Lauren; Chui, Michelle A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-20)
      Over-the-counter (OTC) medications are products that have been made easily accessible to allow patients to treat common ailments without a prescription and the cost of a doctor’s visit. These medications are generally considered safe; however, there is still a potential for these medications to lead to adverse health outcomes. Older adults (ages 50+) are especially susceptible to these adverse health ...

This could also inform the development of quality measures, such as quality indicators (QIs).<p> <p>Aim - To identify key stakeholders' perspectives on the quality of services ...
    • The bacterial magnesium transporter MgtA reveals highly selective interaction with specific cardiolipin species 

      Weikum, Julia; van Dyck, Jeroen F.; Subramani, Saranya; Klebl, David P.; Storflor, Merete; Muench, Stephen P.; Abel, Sören; Sobott, Frank; Morth, Jens Preben (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-23)
      The bacterial magnesium transporter A (MgtA) is a specialized P-type ATPase important for Mg<sup>2+</sup> import into the cytoplasm; disrupted magnesium homeostasis is linked to intrinsic ribosome instability and antibacterial resistance in Salmonella strains. Here, we show that MgtA has functional specificity for cardiolipin 18:1. Still, it reaches maximum activity only in combination with ...
    • Polyethylene glycol (PEG) as a broad applicability marker for LC–MS/MS-based biodistribution analysis of nanomedicines 

      Hyldbakk, Astrid; Hansen, Terkel; Hak, Sjoerd; Borgos, Sven Even F. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-13)
      Polyethylene glycol (PEG) conjugation (PEGylation) is a well-established strategy to improve the pharmacokinetic and biocompatibility properties of a wide variety of nanomedicines and therapeutic peptides and proteins. This broad use makes PEG an attractive ‘allround’ candidate marker for the biodistribution of such PEGylated compounds. This paper presents the development of a novel strategy for ...
