Modeling of Particle Number Fluctuations in Entire Cells

2012

In a recent study we developed a method to model protein diffusion in cells [1], where special attention was given to generating from image data of the measured cell a realistic digital model cell in which protein dynamics were simulated. The method was shown to be well suited for modeling non-equilibrium situations that arise, e.g., in photobleaching experiments, and to be capable of producing more detailed information about protein motion than traditional modeling.Another experimental way to assess protein dynamics is to study fluctuations in the local protein number, as it is done, e.g., in fluorescence correlation spectroscopy (FCS), or in similar measurements that apply single-plane il…

Trans-ancestral GWAS of alcohol dependence reveals common genetic underpinnings with psychiatric disorders

2018

AbstractLiability to alcohol dependence (AD) is heritable, but little is known about its complex polygenic architecture or its genetic relationship with other disorders. To discover loci associated with AD and characterize the relationship between AD and other psychiatric and behavioral outcomes, we carried out the largest GWAS to date of DSM - IV diagnosed AD. Genome - wide data on 14,904 individuals with AD and 37,944 controls from 28 case / control and family - based studies were meta - analyzed, stratified by genetic ancestry (European, N = 46,568; African; N = 6,280). Independent, genome - wide significant effects of different ADH1B variants were identified in European (rs1229984; p = …

Determining disability prevalence is a growing area for population statistics, especially among young adolescents. The Washington Group on Disability Statistics is one source of reporting disabilities through functional difficulties. Yet, young adolescents self-reporting through this measure is in its infancy. The purpose of this study was to carry out an intra-rater test-retest reliability study on a modified set of items for self-reporting functional difficulties. Young adolescents (N = 74; boys = 64%; age M = 13.7, SD = 1.8) with special educational needs in Finland completed a self-reported version of the Child Functioning Module in a supervised classroom. The second administration took…

Responsiveness and Minimal Clinically Important Difference of the Five Times Sit-to-Stand Test in Patients with Stroke

2021

This study aimed to analyze the responsiveness of the 5STS test among stroke patients and to estimate the MCIDs (minimal clinically important differences) for different severity levels of community ambulation and stages of recovery. The 5STS and comparator instruments (gait speed and Functional Ambulatory Category (FAC)) were evaluated at baseline. These measures were repeated at 4 (Stage 1) and 8 weeks (Stage 2), together with the Global Rating of Change (GROC). The MCIDs were calculated with two anchor-based methods using the GROC as the external criterion. Responsiveness to change for the 5STS was estimated analyzing the correlation with changes in the two comparator instruments and thei…

STREET WORKOUT: PERFIL PSICOSOCIAL DE SUS PRACTICANTES

2020

La presente investigación estudia las principales características psicológicas de los practicantes de Street Workout, una modalidad deportiva emergente y en auge en los últimos años. A través de un estudio descriptivo-correlacional, con una muestra de 107 practicantes de España, se elaboró un estudio piloto del perfil psicosocial que incluye la evaluación de los motivos de práctica, la satisfacción muscular, la cohesión y el bienestar psicológico; además de una comparación en función de si compiten. Los resultados señalan que es un deporte practicado mayoritariamente por hombres menores de 23 años, cuya principal motivación es hallar un equilibrio entre la preocupación por la salud y su asp…

PERITRAUMATIC FACTORS AND POSTTRAUMATIC SYMPTOMS IN CHILD SEXUAL ABUSE CASES

2017

Health and legal professionals are aware of adverse effects child sexual abuse (CSA) can have on child development as well as the individual differences in severity of psychological outcomes. The objective of this pilot study was to identify possible explanations that could account for the CSA psychological outcome variability and give insights for further research. A sample of 25 Russian speaking girls by the decision of the person directing the proceedings were recognized as CSA victims and were assigned to psychological or complex psychiatric and psychological expert examination. During examination demographical data was collected and several self-report measures regarding peritraumatic …

Behavioral and Electrophysiological Arguments in Favor of a Relationship between Impulsivity, Risk-Taking, and Success on the Iowa Gambling Task

2019

The aim of the present study was to investigate the relationship between trait impulsivity, risk-taking, and decision-making performance. We recruited 20 healthy participants who performed the Iowa Gambling Task (IGT) and the Balloon Analog Risk Task (BART) to measure decision-making and risk-taking. The impulsivity was measured by the Barratt Impulsiveness Scale. Resting-state neural activity was recorded to explore whether brain oscillatory rhythms provide important information about the dispositional trait of impulsivity. We found a significant correlation between the ability to develop a successful strategy and the propensity to take more risks in the first trials of the BART. Risk-taki…

Social capital and religious and civic participation in Riga, Latvia: findings from the 2014 social survey

2016

ABSTRACTThe article discusses the link between religious and civic participation in Riga based on the data obtained from a social survey in 2014. Religious and civic participation is a prerequisite for building social capital within a local community. Four types of relationships between civic and religious engagement have been identified: (1) individuals with no religious or civic activity; (2) religiously active individuals with no civic activity; (3) individuals involved in civic activities but who are religiously inactive; and (4) individuals involved in both religious and civic activities. Although the survey data indicate a weak correlation between civic and religious activities, relig…

Rho resonance, timelike pion form factor, and implications for lattice studies of the hadronic vacuum polarization

2020

We study isospin-1 P-wave ππ scattering in lattice QCD with two flavors of O(a) improved Wilson fermions. For pion masses ranging from mπ=265 MeV to mπ=437 MeV, we determine the energy spectrum in the center-of-mass frame and in three moving frames. We obtain the scattering phase shifts using Lüscher’s finite-volume quantization condition. Fitting the dependence of the phase shifts on the scattering momentum to a Breit-Wigner form allows us to determine the corresponding ρ mass mρ and gρππ coupling. By combining the scattering phase shifts with the decay matrix element of the vector current, we calculate the timelike pion form factor, Fπ, and compare the results to the Gounaris-Sakurai repr…
