Understanding the Role of Radio-Sensitizing Nanoparticles in Enhancing Pathologic Response in Soft Tissue Sarcomas.

High-atomic-number (Z) nanoparticles produce a cascade of low-energy secondary electrons and characteristic X-rays when ionized by X-ray irradiation. These secondary particles deposit their energy in the vicinity of the nanoparticles and, provided that the latter are selectively accumulated within tumor cells, this results in increased DNA damage and tumor cell deaths. This study reviews the utilization of high-Z nanoparticles in the treatment of soft tissue sarcomas (STS).

Deficiency Reshapes the Phenotypic and Molecular Characteristics of Bone Marrow Adipocytes in Mice.

In the present study, we studied the effect of apolipoprotein A-1 (APOA1) on the spatial and molecular characteristics of bone marrow adipocytes, using well-characterized knockout mice. APOA1 is a central regulator of high-density lipoprotein cholesterol (HDL-C) metabolism, and thus HDL; our recent work showed that deficiency of APOA1 increases bone marrow adiposity in mice. We found that deficient mice have greatly elevated adipocytes within their bone marrow compared to wild type counterparts.

Effects of minimally invasive surgery and functional physiotherapy on motor function of children with cerebral palsy: A non-randomised controlled trial.

Purpose: This non-randomised controlled trial investigated whether a combined programme of functional physiotherapy and minimally invasive orthopaedic surgery improves the level and degree of capacity and performance of gross motor function in children with spastic cerebral palsy (CP).

Methods: Fifty-two children with spastic CP aged 5-7 years, Gross Motor Function Classification System (GMFCS) levels II-IV, were allocated to two equal groups: experimental group (selective percutaneous myofascial lengthening [SPML] procedure and 9-month functional strengthening physiotherapy programme) and control (standard physiotherapy) groups.
