Long-Term Response to Cholinesterase Inhibitor Treatment Is Related to Functional MRI Response in Alzheimer's Disease.

2015

<b><i>Background:</i></b> Treatment of Alzheimer's disease (AD) with cholinesterase inhibitors (ChEI) enhances cholinergic activity and alleviates clinical symptoms. However, there is variation in the clinical response as well as system level changes revealed by functional MRI (fMRI) studies. <b><i>Methods:</i></b> We investigated 18 newly diagnosed mild AD patients with fMRI using a face recognition task after a single oral dose of rivastigmine, a single dose of placebo and 1-month treatment with rivastigmine. The clinical follow-up took place at 6 and 12 months. <b><i>Results:</i></b> MMSE score difference between bas…

Explaining Mobile Commerce Usage Intention Based on Technology Acceptance Models in a Developing Market Context

2021

Purpose – This paper aims to explain the intention to use mobile phones for shopping based on the technology acceptance model (TAM) and the unified theory of acceptance and use of technology (UTAUT2) model in a developing country context, characterized by the mobile channel’s high growth rates. The research model analyzes perceived usefulness, perceived ease of use, social influence, facilitating conditions, and hedonic motivation on m-commerce usage intention. Design/Methodology/Approach – Data for the research were collected through a survey among mobile commerce users in Ecuador. We tested the model through partial least squares structural equations modeling (PLS-SEM). Findings and impli…

Blistering mechanisms of atomic-layer-deposited AlN and Al2O3 films

2017

Blistering of protective, structural, and functional coatings is a reliability risk pestering films ranging from elemental to ceramic ones. The driving force behind blistering comes from either excess hydrogen at the film-substrate interface or stress-driven buckling. Contrary to the stress-driven mechanism, the hydrogen-initiated one is poorly understood. Recently, it was shown that in the bulk Al-Al2O3 system, the blistering is preceded by the formation of nano-sized cavities on the substrate. The stress-and hydrogen-driven mechanisms in atomic-layer-deposited (ALD) films are explored here. We clarify issues in the hydrogen-related mechanism via high-resolution microscopy and show that at…

Mechanisms of Smartphone Apps for Cigarette Smoking Cessation: Results of a Serial Mediation Model From the iCanQuit Randomized Trial

2021

Background Engagement with digital interventions is a well-known predictor of treatment outcomes, but this knowledge has had limited actionable value. Instead, learning why engagement with digital interventions impact treatment outcomes can lead to targeted improvements in their efficacy. Objective This study aimed to test a serial mediation model of an Acceptance and Commitment Therapy (ACT) smartphone intervention for smoking cessation. Methods In this randomized controlled trial, participants (N=2415) from 50 US states were assigned to the ACT-based smartphone intervention (iCanQuit) or comparison smartphone intervention (QuitGuide). Their engagement with the apps (primary measure: numb…

The Effects of Acceptance and Commitment Therapy (ACT) Intervention on Inflammation and Stress Biomarkers : a Randomized Controlled Trial

2020

Abstract Background Psychological processes can be manifested in physiological health. We investigated whether acceptance and commitment therapy (ACT), targeted on psychological flexibility (PF), influences inflammation and stress biomarkers among working-age adults with psychological distress and overweight/obesity. Method Participants were randomized into three parallel groups: (1) ACT-based face-to-face (n = 65; six group sessions led by a psychologist), (2) ACT-based mobile (n = 73; one group session and mobile app), and (3) control (n = 66; only the measurements). Systemic inflammation and stress markers were analyzed at baseline, at 10 weeks after the baseline (post-intervention), and…

Does a Mindfulness-, Acceptance-, and Value-Based Intervention for Burnout Have Long-Term Effects on Different Levels of Subjective Well-Being?

2020

This study investigated whether beneficial intervention effects on burnout and mindfulness skills diffuse and facilitate the long-term development of different levels of subjective well-being: experiential (perceived stress), eudaimonic (psychological and social well-being), and evaluative (life satisfaction). Participants were Finnish employees with notable burnout (n = 105, 80% women). The study utilized individual profiles of burnout and mindfulness skills identified in a previous study (Kinnunen, Puolakanaho, Tolvanen, Mäkikangas, & Lappalainen, 2019). The profiles were based on levels and changes in burnout and mindfulness skills during an 8-week intervention and 4-month follow-up. In …
