    • Toxicity Assessment of Resveratrol Liposomes-in-Hydrogel Delivery System by EpiVaginal Tissue Model 

      Jøraholmen, May Wenche; Damdimopoulou, Pauliina; Acharya, Ganesh; Skalko-Basnet, Natasa (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-17)
      The natural polyphenol resveratrol (RES) has shown great potential as an antimicrobial, including against microbes associated with vaginal infections. To fully exploit the activities of RES, an all-natural ingredients formulation for RES delivery at vaginal site has been developed, namely liposomes loaded with RES, incorporated into a chitosan hydrogel as secondary vehicle. Although considered ...

      Starikova, Irina; Harms, Klaus; Haugen, Pål; Lunde, Tracy Munthali; Primicerio, Raul; Samuelsen, Ørjan; Nielsen, Kaare Magne; Johnsen, Pål Jarle (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Horizontal gene transfer (HGT) plays a major role in bacterial microevolution as evident from the rapid emergence and spread of antimicrobial drug resistance. Few studies have however addressed the population dynamics of newly imported genetic elements after HGT. Here, we show that newly acquired class-1 integrons from Salmonella enterica serovar Typhimurium and Acinetobacter baumannii, free of ...

      Warr, Alyson R; Hubbard, Troy P; Munera, Diana; Blondel, Carlos J; Abel zur Wiesch, Pia; Abel, Sören; Wang, Xiaoxue; Davis, Brigid M.; Waldor, Matthew K. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-12)
      Enterohemorrhagic <i>Escherichia coli</i> O157:H7 (EHEC) is an important food-borne pathogen that colonizes the colon. Transposon-insertion sequencing (TIS) was used to identify genes required for EHEC and <i>E. coli</i> K-12 growth <i>in vitro</i> and for EHEC growth <i>in vivo</i> in the infant rabbit colon. Surprisingly, many conserved loci contribute to EHEC’s but not to K-12’s growth <i>in ...

    • Understanding the binding of inhibitors of matrix metalloproteinases by molecular docking, quantum mechanical calculations, molecular dynamics simulations, and a MMGBSA/MMBappl study 

      Singh, Tanya; Adekoya, Olayiwola; Jayaram, B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-14)
      Matrix metalloproteinases (MMPs) consist of a class of proteins required for normal tissue function. Their over expression is associated with many disease states and hence the interest in MMPs as drug targets. Almost all MMP inhibitors have been reported to fail in clinical trials due to lack of specificity. Zinc in the binding site of metalloproteinases performs essential biological functions ...

      Salbu, Linda; Picker-Freyer, Katharina M.; Schmid, Wolfgang; Bauer-Brandl, Annette; Tho, Ingunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      This study examines the contribution of the 3-D model in an early development set-up for pectin tablets. Therefore, the aim of this work is to extract as much information on the compression behaviour from as few tablets as possible. Pectins with various degrees of methoxylation (DM) were studied (4-72%). The compressibility was evaluated by classical “in-die” Heckel and Kawakita analyses in addition ...

    • Using chemical reaction kinetics to predict optimal antibiotic treatment strategies 

      Abel zur Wiesch, Pia; Clarelli, Fabrizio; Cohen, Ted (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-06)
      Identifying optimal dosing of antibiotics has proven challenging—some antibiotics are most effective when they are administered periodically at high doses, while others work best when minimizing concentration fluctuations. Mechanistic explanations for why antibiotics differ in their optimal dosing are lacking, limiting our ability to predict optimal therapy and leading to long and costly experiments. ...

      Tran, Vi Ngoc-Nha; Shams, Alireza; Ascioglu, Sinan; Martinecz, Antal; Liang, Jingyi; Clarelli, Fabrizio; Mostowy, Rafal; Cohen, Ted; Abel zur Wiesch, Pia (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-06)
      Background: As antibiotic resistance creates a signifcant global health threat, we need not only to accelerate the development of novel antibiotics but also to develop better treatment strategies using existing drugs to improve their efcacy and prevent the selection of further resistance. We require new tools to rationally design dosing regimens from data collected in early phases of antibiotic ...

      Carbapenem-resistant Gram-negative pathogens are a critical public health threat and there is an urgent need for new treatments. Carbapenemases (β-lactamases able to inactivate carbapenems) have been identified in both serine β-lactamase (SBL) and metallo-β-lactamase (MBL) families. The recent introduction of SBL carbapenemase inhibitors has provided alternative therapeutic options. Unfortunately, ...
