Tailored anti-biofilm activity – Liposomal delivery for mimic of small antimicrobial peptide
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-13)The eradication of bacteria embedded in biofilms is among the most challenging obstacles in the management of chronic wounds. These biofilms are found in most chronic wounds; moreover, the biofilm-embedded bacteria are considerably less susceptible to conventional antimicrobial treatment than the planktonic bacteria. Antimicrobial peptides and their mimics are considered attractive candidates in the ... -
Potential Safety Issues With Combined Use of Dietary Supplements and Medication – Focus on Interactions
(Chapter; Bokkapittel, 2022-11-09)The use of dietary supplements (DS) is widespread and tends to increase with age and female gender. DS use can in some situations represent a safety risk for patients. For instance, concomitant use of medication and dietary supplements, particularly herbal remedies, may cause clinically significant pharmacological interactions. The study underlying this chapter aimed to investigate the prevalence ... -
Evolutionary Instability of Collateral Susceptibility Networks in Ciprofloxacin-Resistant Clinical Escherichia coli Strains
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-07)ABSTRACT Collateral sensitivity and resistance occur when resistance development toward one antimicrobial either potentiates or deteriorates the effect of others. Previous reports on collateral effects on susceptibility focus on newly acquired resistance determinants and propose that novel treatment guidelines informed by collateral networks may reduce the evolution, selection, and spread of ... -

Mechanisms of antibiotic action shape the fitness landscapes of resistance mutations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-24)Antibiotic-resistant pathogens are a major public health threat. A deeper understanding of how an antibiotic’s mechanism of action influences the emergence of resistance would aid in the design of new drugs and help to preserve the effectiveness of existing ones. To this end, we developed a model that links bacterial population dynamics with antibiotic-target binding kinetics. Our approach allows ... -
Chitosan-based delivery system enhances antimicrobial activity of chlorhexidine
(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 ... -
Nucleic acid peptide nanogels for the treatment of bacterial keratitis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-14)Cage-shaped nucleic acid nanocarriers are promising molecular scaffolds for the organization of polypeptides. However, there is an unmet need for facile loading strategies that truly emulate nature's host–guest systems to drive encapsulation of antimicrobial peptides (AMPs) without loss of biological activity. Herein, we develop DNA nanogels with rapid in situ loading of L12 peptide during the thermal ... -
Behavior of E. coli ST131 regarding the acquisition of a blaOXA-48 encoding plasmid
(Master thesis; Mastergradsoppgave, 2021-05-11)Antimicrobial resistance has been a challenge ever since the discovery of antibiotics. The rising challenge of resistance has led to the increased use of last-resort antibiotics: carbapenems. It is predicted that a successful E. coli clone, ST131 is apt for the acquisition of carbapenem-resistance encoding plasmids. In this study, we aim to understand how E. coli ST131 respond to acquisition of ... -
Mercaptoalkanol-derived self-immolative linkers for bioconjugates. Synthesis and analysis
(Master thesis; Mastergradsoppgave, 2021-01-11)Many of the anticancer compounds discovered through synthesis or bioprospecting activities are found to be equally toxic to healthy cells and tumors. Consequently, these compounds are not considered as promising drug candidates worthy of further study. This project seeks to develop a novel chemical toolkit that can be utilized to increase the therapeutic value of such toxic compounds by decreasing ... -
