(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-27)
      We report a series of synthetic cationic amphipathic barbiturates inspired by the pharmacophore model of small antimicrobial peptides (AMPs) and the marine antimicrobials eusynstyelamides. These N,N′-dialkylated-5,5-disubstituted barbiturates consist of an achiral barbiturate scaffold with two cationic groups and two lipophilic side chains. Minimum inhibitory concentrations of 2–8 μg/mL were achieved ...

      Objective: Attention–deficit/hyperactivity disorder (ADHD) symptoms have been linked to suicidal behavior. However, little is known about the mechanisms involved in this association. This study examined ADHD symptoms and suicidal ideation during the COVID-19 pandemic and the role of self–perceived stress in this association.<p> <p>Method: Data were analyzed from an online sample of 1,452 Japanese ...

      The increased prevalence of chronic wounds requires novel treatment options. The aim of this study was to develop a beta-glucan (βG)-loaded nanofiber wound dressing. Nanofibers were prepared using the needle-free Nanospider™ technology, an electrospinning method which enables the production of nanofibers at an industrial scale. The βG was selected as active ingredient based on its confirmed wound ...

      Koposov, Roman A; Isaksson, Johan; Vermeiren, Robert; Schwab-Stone, Mary; Stickley, Andrew; Ruchkin, Vladislav (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-27)
      <i>Background</i>: Many children and adolescents experience violent events which can be associated with negative consequences for their development, mental health, school, and social functioning. However, findings between settings and on the role of gender have been inconsistent. This study aimed to investigate cross-country and gender differences in the relationship between community violence ...

      Research among adolescents exploring the association between depressive symptoms and aggression has produced inconsistent findings. This study investigated the prevalence of clinically significant (current major depressive episode) and subthreshold depressive symptoms in a general population sample of adolescents from Northern Russia and explored their association with aggression and anger, while ...

    • Risky sexual behaviour among Russian adolescents: association with internalizing and externalizing symptoms 

      Isaksson, Johan; Westermark, Caroline; Koposov, Roman A; Stickley, Andrew; Ruchkin, Vladislav (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-09)
      <i>Background</i> - Risky sexual behaviour (RSB) is regarded as a major health problem during adolescence. Russia has one of the highest rates of teenage pregnancy, abortion and newly diagnosed HIV infections in the world, but research on RSB in Russian youth has been limited. To address this deficit, this study examined the role of several factors, including internalizing and externalizing symptoms, ...
