Multispecies coinfections and presence of antibiotics shape resistance and fitness costs in a pathogenic bacterium

2023

Increasing antimicrobial resistance (AMR) poses a challenge for treatment of bacterial diseases. In real life, bacterial infections are typically embedded within complex multispecies communities and influenced by the environment, which can shape costs and benefits of AMR. However, knowledge of such interactions and their implications for AMR in vivo is limited. To address this knowledge gap, we investigated fitness-related traits of a pathogenic bacterium (Flavobacterium columnare) in its fish host, capturing the effects of bacterial antibiotic resistance, coinfections between bacterial strains and metazoan parasites (fluke Diplostomum pseudospathaceum) and antibiotic exposure. We quantifie…

Long-term strength and balance training prevents mobility decline among community-dwelling people aged 75 and older

2016

High functional capacity of muscle strength and balance in older persons promotes independent mobility and prevents functional decline below the disability threshold. This dissertation explored the effects of strength and balance training (SBT) as part of a multimodal geriatric intervention on physical functioning and health-related factors associated with training participation in a community-dwelling population aged 75 years and over. This study is a part of the Geriatric Multidisciplinary Strategy for the Good Care of the Elderly (GeMS) project conducted from 2004 to 2007 in Kuopio, Finland. Participants were randomized into an intervention (n=339) and control group (n=312). The individu…

Electrical conductivity of glass fiber-reinforced plastic with nanomodified matrix for damage diagnostic

2021

The electrical conductivity of glass fiber-reinforced plastic (GFRP) with epoxy matrix modified by multiwall carbon nanotubes (MWCNT) was studied. The electrical conductivity of nanomodified lamina and multi-layered GFRP was investigated on several levels using a structural approach. Components of the electrical conductivity tensor for unidirectional-reinforced monolayer were calculated similarly as in micromechanics using the conductivity of the nanomodified matrix. The electrical conductivity of multilayer composite was calculated using laminate theory and compared with values measured experimentally for various fiber orientation angles. Calculated and experimental data were in good agree…

Biopolymer Recovery from Aerobic Granular Sludge and Conventional Flocculent Sludge in Treating Industrial Wastewater: Preliminary Analysis of Differ…

2022

The recovery of biopolymers from sewage sludge could be a crucial step in implementing circular economy principles in wastewater treatment plants (WWTP). In this frame, the present study was aimed at evaluating the simultaneous production of polyhydroxyalkanoates (PHA) and extracellular polymeric substances (EPS) obtainable from the treatment of agro-industrial wastewater. Two biological enrichment systems, aerobic granular sludge (AGS) and a conventional activated sludge operating as a sequencing batch reactor (SBR), were monitored for 204 and 186 days, respectively. The maximum biopolymers accumulation capacity was close to 0.60 mgPHA-EPS gVSS−1 in the AGS when operating at 3 kgCODm…

Weighted and unweighted distances based decision tree for ranking data

2018

Preference data represent a particular type of ranking data (widely used in sports, web search, social sciences), where a group of people gives their preferences over a set of alternatives. Within this framework, distance-based decision trees represent a non-parametric tool for identifying the profiles of subjects giving a similar ranking. This paper aims at detecting, in the framework of (complete and incomplete) ranking data, the impact of the differently structured weighted distances for building decision trees. The traditional metrics between rankings don’t take into account the importance of swapping elements similar among them (element weights) or elements belonging to the top (or to …

Lettura e Composizione Integrate Cooperative nella Didattica a Distanza: esaminare gli Effetti su Studenti Universitari

2022

Per promuovere negli studenti la scrittura come attività consapevole e sistematica per lo studio può risultare efficace il Cooperative Integrated Reading and Composition (CIRC) Model, che si concentra sulla padronanza combinata di strategie di comprensione e di composizione. In rapporto essenziale con la lettura, la co-costruzione di testi stimola gli studenti a esercitare molteplici capacità: analizzare e sintetizzare, immaginare e anticipare, scegliere e selezionare, integrare e elaborare, organizzare i contenuti riguardo a situazioni comunicative e destinatari diversi. Nel presente contributo l’esercizio delle abilità di leggere e comporre testi è stato indagato su un gruppo di studenti …

Western Australian students' alcohol consumption and expenditure intentions for Schoolies.

2016

In Australia, the immediate post-school period (known as ‘Schoolies’) is associated with heavy drinking and high levels of alcohol-related harm. This study investigated students’ intended alcohol consumption during Schoolies to inform interventions to reduce alcohol-related harm among this group. An online survey was administered to students in their senior year of schooling. Included items related to intended daily alcohol consumption during Schoolies, amount of money intended to be spent on alcohol over the Schoolies period, and past drinking behaviour. On average, participants (n=187) anticipated that they would consume eight standard drinks per day, which is substantially higher than t…

Mediating Effects of Global Negative Effect Expectancies on the Association between Problematic Cannabis Use and Social Anxiety

2017

The relationship between social anxiety and cannabis use among adolescents and young adults is a highly debated topic. In this cross-sectional study, we tested whether cannabis use expectancies mediated the association between social anxiety and cannabis use severity in a sample of 343 young adults (74.3% male) who used cannabis. They completed self-report measures for the screening of problematic cannabis use (Cannabis Use Problems Identification Test) and social anxiety symptoms (Social Interaction Anxiety Scale and Social Phobia Scale). A multiple mediation analysis was used to test whether marijuana effect expectancies mediate social anxiety effect on problematic cannabis use. Social an…

Longitudinal physical activity patterns and the development of cardiometabolic risk factors during adolescence

2023

Purpose To examine the associations between longitudinal physical activity (PA) patterns and the development of cardiometabolic risk factors from adolescence to young adulthood. Methods This cohort study encompassed 250 participants recruited from sports clubs and schools, and examined at mean age 15 and 19. Device-measured moderate-to-vigorous PA was grouped into five patterns (via a data-driven method, using inactivity maintainers as a reference). The outcomes were: glucose, insulin, homeostasis model assessment for insulin resistance (HOMA-IR), total cholesterol, HDL and LDL cholesterol, triglycerides, blood pressure, and body mass index (BMI). Linear growth curve models were applied wit…
