Can Peer Acceptance and Perceptual Accuracy Impact the Effectiveness of Two Formats of a Preventative Intervention on Functional Subtypes of Aggression in Youth?

Coping Power (CP) is an empirically supported school-based intervention for children at risk for aggression. A child's social status with peers and the extent to which they accurately perceive it are important aspects of preadolescent social development that may influence how intervention format affects disruptive behavior outcomes. Further, reactive (RA) and proactive (PA) functional subtypes of aggression have differential relations with peer acceptance.

Immune Checkpoint Molecules as Biomarkers of Staphylococcus aureus Bone Infection and Clinical Outcome.

Staphylococcus aureus prosthetic joint infections (PJIs) are broadly considered incurable, and clinical diagnostics that guide conservative vs. aggressive surgical treatments do not exist. Multi-omics studies in a humanized NSG-SGM3 BLT mouse model demonstrate human T cells: 1) are remarkably heterogenous in gene expression and numbers, and 2) exist as a mixed population of activated, progenitor-exhausted, and terminally-exhausted Th1/Th17 cells with increased expression of immune checkpoint proteins (LAG3, TIM-3).

The polarity of high-definition transcranial direct current stimulation affects the planning and execution of movement sequences.

Noninvasive brain stimulation of the primary motor cortex has been shown to alter therapeutic outcomes in stroke and other neurological conditions, but the precise mechanisms remain poorly understood. Determining the impact of such neurostimulation on the neural processing supporting motor control is a critical step toward further harnessing its therapeutic potential in multiple neurological conditions affecting the motor system. Herein, we leverage the excellent spatio-temporal precision of magnetoencephalographic (MEG) imaging to identify the spectral, spatial, and temporal effects of high-definition transcranial direct current stimulation (HD-tDCS) on the neural responses supporting motor control.

Treadmill belt accelerations may not accurately replicate kinematic responses to tripping on an obstacle in older people.

Background: Treadmill belt perturbations have high clinical feasibility for use in perturbation-based training in older people, but their kinematic validity is unclear. This study examined the kinematic validity of treadmill belt accelerations as a surrogate for overground walkway trips during gait in older people.

Methods: Thirty-eight community-dwelling older people were exposed to two unilateral belt accelerations (8 m s-2) whilst walking on a split-belt treadmill and two trips induced by a 14 cm trip-board whilst walking on a walkway with condition presentation randomised.
