Response speed to a signal is faster when advance information about the forthcoming movement is provided before signal onset. Although this precuing effect is well established, the location of this saving in reaction time (RT) in the information-processing system is controversial. Some authors have claimed that the precuing effect resides at a motoric level, whereas others have suggested a nonmotoric locus. The present experiments used onset latencies of the lateralized readiness potential (LRP) to locate the precuing effect. The results of 2 experiments with a highly compatible (Experiment 1) and with an incompatible (Experiment 2) stimulus-response mapping indicate that this effect resides, at least partially, in the motoric portion of RT. In addition, the LRP amplitude before signal appearance increased with the amount of advance information, supporting a muscle-specific preparation hypothesis.

Retention of CAD-CAM locator retentive attachment insert in mandibular implant overdenture.
BMC Oral Health
January 2025
Removable Prosthodontics Department, Faculty of Dentistry, October 6 University, Giza, Egypt.
Background: The continuous development in digital prosthodontics allowed the customization of attachments and retentive inserts which offers an easy and cheap solution for regular maintenance of locator overdentures during daily practice. The present study compared the change in retention values of the fully digitally manufactured custom-made locator attachment retentive insert with the ready-made ones after insertion, removal, and masticatory cycles.
Methods: A complete denture was constructed over a mandibular edentulous epoxy model.
Radiological Outcome in Reverse Shoulder Arthroplasty does not correlate with patient satisfaction or quality of life.
J Shoulder Elbow Surg
December 2024
Department of Trauma Surgery and Orthopedics - Medical University of Vienna, AKH Wien, Vienna, Austria. Electronic address:
Background: While outcomes following reverse shoulder arthroplasty (rTSA) have often been gauged through radiological assessments focusing on prosthesis position, there is increasing recognition of patient-reported outcomes, particularly satisfaction, as indicators of surgical success. The objective of this study was to correlate radiological findings with clinical outcomes, patient satisfaction, and health-related quality of life (HRQoL).
Materials And Methods: A retrospective evaluation was conducted on patients following rTSA at a minimum of two years postoperatively.
Return to Sport After ACL Reconstruction With Meniscal Allograft Transplantation Versus Isolated ACL Reconstruction: A Matched-Cohort Study.
Am J Sports Med
January 2025
Memorial Hermann Rockets Sports Medicine Institute, Department of Sports Medicine & Rehabilitation, Houston, Texas, USA.
Background: Meniscal allograft transplantation (MAT) is indicated in the setting of anterior cruciate ligament (ACL) reconstruction to restore proper arthrokinematics and load distribution for the meniscus-deficient knee. Objective outcomes after ACL reconstruction with concomitant MAT in athletic populations are scarcely reported and highly variable.
Purpose: To compare patient outcomes using an objective functional performance battery, self-reported outcome measures, and return-to-sport rates between individuals undergoing ACL reconstruction with concomitant MAT and a matched group undergoing isolated ACL reconstruction.

Brain development is highly complex and dynamic. During this process, the different brain structures acquire new components, such as the cerebral cortex, which builds up different germinal and cortical layers during its development. The genetic study of this complex structure has been commonly approached by bulk-sequencing of the entire cortex as a whole.

Volition is conceived as a set of orchestrated executive functions, which can be characterized by features, such as reason-based and goal-directedness, driven by endogenous signals. The lateral prefrontal cortex (LPFC) has long been considered to be responsible for cognitive control and executive function, and its neurodynamics appears to be central to goal-directed cognition. In order to address both associative processes (i.
