Behavioural and neuroplastic effects of a double-blind randomised controlled balance exercise trial in people with Parkinson's disease.

Balance dysfunction is a disabling symptom in people with Parkinson's disease (PD). Evidence suggests that exercise can improve balance performance and induce neuroplastic effects. We hypothesised that a 10-week balance intervention (HiBalance) would improve balance, other motor and cognitive symptoms, and alter task-evoked brain activity in people with PD.

Evaluation of a statewide initiative to reduce expulsion of young children.

This program evaluation study describes 3 years of implementation of Arkansas's BehaviorHelp (BH) system, a statewide expulsion prevention support system for early care and education (ECE). BH coordinates three tiers of supports to ECE professionals, including phone support, on-site technical assistance (TA), and infant and early childhood mental health consultation (IECMHC). We examine differences in characteristics of those served across BH service tiers, describe short-term case outcomes, and explore factors associated with expulsions.

Understanding factors affecting participation in online formative quizzes: an interview study.

A positive correlation between performance and participation in formative quizzes and final summative examinations has been reported many times. The goal of the present interview study was to construct a model to explain why students may elect not to engage with formative assessment opportunities. Our medical school's preclinical curriculum has an established policy of offering weekly online quizzes in all courses during the first 2 yr.

Naip5 affects host susceptibility to the intracellular pathogen Legionella pneumophila.

Background: Legionella pneumophila is a gram-negative bacterial pathogen that is the cause of Legionnaires' Disease. Legionella produces disease because it can replicate inside a specialized compartment of host macrophages. Macrophages isolated from various inbred mice exhibit large differences in permissiveness for intracellular replication of Legionella.
