Abstract Representation of Movement Parameters in Basal Ganglia Output

Advanced Science, EarlyView.
The basal ganglia output provides a scalable velocity/position signal across behavioral contexts, supporting the idea that these variables are represented in the brain as abstract entities rather than as fixed changes in joint angles or specific sets of body effectors.

Preliminary focus on the mechanical and antibacterial activity of a PMMA-based bone cement loaded with gold nanoparticles

Bioactive Materials, 2017
In total knee arthroplasty (TKA) and total hip replacement (THR) the restoration of the normal joint function represents a fundamental feature. A prosthetic joint must be able to provide motions and to transmit functional loads.

A Comparison of Percutaneous Kyphoplasty with High-Viscosity and Low-Viscosity Bone Cement for Treatment of Osteoporotic Vertebral Compression Fractures: A Retrospective Study

Geriatric Orthopaedic Surgery & Rehabilitation, 2022
Background Osteoporotic vertebral compression fracture (OVCF) has become a health issue of worldwide concern. Percutaneous kyphoplasty (PKP) is one of the main surgical methods for OVCFs. This study aimed to evaluate and compare the clinical efficacy and

An Adenoviral‐Vectored Tp0326 Vaccine Elicits Robust Functional Antibodies to Prevent Treponema pallidum Dissemination in a Rabbit Model

Advanced Science, EarlyView.
Vaccination promotes cellular infiltration into primary lesions and effectively inhibits T. pallidum dissemination to distal organs. Notably, transfer of lesion tissue from immunized animals fails to establish infection in naive recipients, confirming specific protective immunity.

Biomechanical Effects of Cement Distribution in the Fractured Area on Symptomatic Osteoporotic Vertebral Compression Fractures: A Three-Dimensional Finite Element Analysis

Global Spine Journal, 2015
Introduction According to some clinical studies, insufficient cement distribution in fractured area and asymmetrical cement distribution around fractured area were thought to be the reasons for unrelieved pain and recollapse after percutaneous vertebral ...

Outcomes of cement beads and cement spacers in the treatment of bone defects associated with post-traumatic osteomyelitis

BMC Musculoskeletal Disorders, 2017
Background Cement spacers (Masquelet technique) have traditionally been used for the treatment of segmental bone defects. However, no reports have used cement spacers for the treatment of small/partial segmental bone defects associated with osteomyelitis
