Chitosan and liposomal delivery systems for epicatechin or propyl gallate targeting localized treatment of vulvovaginal candidiasis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-18)Natural polyphenols are promising alternatives to antifungals for novel treatments of vulvovaginal candidiasis (VVC) in an era of antimicrobial resistance. However, polyphenols are poorly soluble and prone to degradation. To overcome their limitations, we propose incorporation in liposomes. The study aimed to develop chitosan and liposome comprising delivery systems for epicatechin (EC) or propyl ... -

The recombination initiation functions DprA and RecFOR suppress microindel mutations in Acinetobacter baylyi ADP1
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-17)Short-Patch Double Illegitimate Recombination (SPDIR) has been recently identified as a rare mutation mechanism. During SPDIR, ectopic DNA single-strands anneal with genomic DNA at microhomologies and get integrated during DNA replication, presumably acting as primers for Okazaki fragments. The resulting microindel mutations are highly variable in size and sequence. In the soil bacterium Acinetobacter ... -

Plasma tryptophan pathway metabolites quantified by liquid chromatography-tandem mass spectrometry as biomarkers in neuroendocrine tumor patients
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-15)A good and accessible biomarker is of great clinical value in neuroendocrine tumor (NET) patients, especially considering its frequently indolent nature and long-term follow-up. Plasma chromogranin A (CgA) and 5-hydroxyindoleacetic acid (5-HIAA) are currently used as biomarkers in NET, but their sensitivity and specificity are restricted. 5-HIAA is the main metabolite of serotonin, an important ... -

Exploring the impact of pharmacist-supported medication reviews in dementia care: experiences of general practitioners and nurses
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-14)Background Dementia is a major global public health challenge, and with the growing elderly population, its prevalence is expected to increase in the coming years. In Sweden, municipalities are responsible for providing special housing for the elderly (SÄBO), which offers services and care for older individuals needing specific support. SÄBO is both the person´s home and a care environment and ... -
Deep sequencing of Escherichia coli exposes colonisation diversity and impact of antibiotics in Punjab, Pakistan
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-18)Multi-drug resistant (MDR) E. coli constitute a major public health burden globally, reaching the highest prevalence in the global south yet frequently flowing with travellers to other regions. However, our comprehension of the entire genetic diversity of E. coli colonising local populations remains limited. We quantified this diversity, its associated antimicrobial resistance (AMR), and assessed ... -
Lipidome Plasticity Enables Unusual Photosynthetic Flexibility in Arctic vs. Temperate Diatoms
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-27)The diatom lipidome actively regulates photosynthesis and displays a high degree of plasticity in response to a light environment, either directly as structural modifications of thylakoid membranes and protein–pigment complexes, or indirectly via photoprotection mechanisms that dissipate excess light energy. This acclimation is crucial to maintaining primary production in marine systems, particularly ... -
The Biofilm Lifestyle Shapes the Evolution of β-Lactamases
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-15)The evolutionary relationship between the biofilm lifestyle and antibiotic resistance enzymes remains a subject of limited understanding. Here, we investigate how β-lactamases affect biofilm formation in Vibrio cholerae and how selection for a biofilm lifestyle impacts the evolution of these enzymes. Genetically diverse β-lactamases expressed in V. cholerae displayed a strong inhibitory effect on ... -
Using real world data for pharmacoeconomic assessments - a case study
(Mastergradsoppgave; Master thesis, 2024-05-14)Pembrolizumab monotherapy for non-small cell lung cancer (NSCLC) was deemed not cost-effective due to limited data, high uncertainty regarding long term results and a considerable budget impact. However, due to confidential price agreements it was approved in 2017, as first-line treatment for metastatic NSCLC that expresses PD-L1 ≥ 50 %. Given potential discrepancies between clinical efficacy and ... -

Isolation and Biological Evaluation of Phomenins from the Marine Fungus Parafenestella sp.
(Mastergradsoppgave; Master thesis, 2024-05-15)Background: Marine fungi are prolific producers of secondary metabolites. Phomenin A (2) and B (3) are secondary metabolites produced by Parafenestella sp. Previous studies have described them as bioactive, but due to the limited availability of pure compounds, their bioactivity has yet to be extensively characterised. These compounds were identified and isolated at Marbio, but the quantities obtained ... -

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