Histological effects of combined therapy involving scar resection, decellularized scaffolds, and human iPSC-NS/PCs transplantation in chronic complete spinal cord injury.

Chronic complete spinal cord injury (SCI) is difficult to treat because of scar formation and cavitary lesions. While human iPS cell-derived neural stem/progenitor cell (hNS/PC) therapy shows promise, its efficacy is limited without the structural support needed to address cavitary lesions. Our study investigated a combined approach involving surgical scar resection, decellularized extracellular matrix (dECM) hydrogel as a scaffold, and hNS/PC transplantation.

Department of Endocrinology and Nutrition, Hospital Universitario de Puerta de Hierro Majadahonda, Madrid, Spain.
Purpose: Studies focused on the effects of sellar and/or perisellar (S/PS) meningiomas on pituitary function are scarce. The primary objective of the present study was to determinate the effects that S/PS meningiomas and their treatments have on pituitary function. Also, we described the clinical characteristics and therapeutic outcomes of the cohort of adult Spanish patients.

Department of Chemical Engineering, Kyoto University, Nishi-kyoku, Kyoto, 615-8510, Japan.
The actomyosin cytoskeleton, a protein assembly comprising actin fibers and the myosin molecular motor, drives various cellular dynamics through contractile force generation at high densities. However, the relationship between the density dependence of the actomyosin cytoskeleton and force-controlled ordered structure remains poorly understood. In this study, we measured contraction-driven flow generation by varying the concentration of cell extracts containing the actomyosin cytoskeleton and associated nucleation factors.

December 2024
Dementia Research Centre, Department of Neurodegenerative Disease, UCL Queen Square Institute of Neurology, University College London, 1st Floor, 8-11 Queen Square, London, WC1N 3AR, UK.
Previous research suggests that emotional prosody perception is impaired in neurodegenerative diseases like Alzheimer's disease (AD) and primary progressive aphasia (PPA). However, no previous research has investigated emotional prosody perception in these diseases under non-ideal listening conditions. We recruited 18 patients with AD, and 31 with PPA (nine logopenic (lvPPA); 11 nonfluent/agrammatic (nfvPPA) and 11 semantic (svPPA)), together with 24 healthy age-matched individuals.

Sci Rep
December 2024
Auckland Bioengineering Institute, The University of Auckland, Auckland, New Zealand.
Cardiac sex-difference functional studies have centred on measurements of twitch force and Ca dynamics. The energy expenditures from these two cellular processes: activation (Ca handling) and contraction (cross-bridge cycling), have not been assessed, and compared, between sexes. Whole-heart studies measuring oxygen consumption do not directly measure the energy expenditure of these activation-contraction processes.
