Photoacoustic Silk Scaffolds for Neural stimulation and Regeneration [PDF]
arXiv, 2021 Neural interfaces using biocompatible scaffolds provide crucial properties for the functional repair of nerve injuries and neurodegenerative diseases, including cell adhesion, structural support, and mass transport. Neural stimulation has also been found to be effective in promoting neural regeneration.

p75NTR as a Molecular Memory Switch [PDF]
, 2019 In recent years, many molecular and environmental factors have been studied to understand how synaptic plasticity is modulated. Sleep, as an evolutionary conserved biological function, has shown to be a critical player for the consolidation and filtering of synaptic circuitry underlying memory traces.

Score predictor factor analysis: Reproducing observed covariances by means of factor score predictors [PDF]
Front. Psychol. 10:1895 (2019), 2019 The model implied by factor score predictors does not reproduce the non-diagonal elements of the observed covariance matrix as well as the factor loadings. It is therefore investigated whether it is possible to estimate factor loadings for which the model implied by the factor score predictors optimally reproduces the non-diagonal elements of the ...

Effect of selegiline on neural stem cells differentiation: a possible role for neurotrophic factors [PDF]
Iranian Journal of Basic Medical Sciences, 2015 Objective(s): The stimulation of neural stem cells (NSCs) differentiation into neurons has attracted great attention in management of neurodegenerative disease and traumatic brain injury. It has been reported that selegiline could enhance the morphologic

Adaptive Sparse Structure Development with Pruning and Regeneration for Spiking Neural Networks [PDF]
arXiv, 2022 Spiking Neural Networks (SNNs) are more biologically plausible and computationally efficient. Therefore, SNNs have the natural advantage of drawing the sparse structural plasticity of brain development to alleviate the energy problems of deep neural networks caused by their complex and fixed structures. However, previous SNNs compression works are lack

Pharmaceuticals, 2023 The limited expression of neurotrophic factors that can be included in neural tissue engineering scaffolds is insufficient for sustained neural regeneration. A localized and sustained method of introducing neurotrophic factors is required.

The trade-off between factor score determinacy and the preservation of inter-factor correlations [PDF]
arXiv, 2023 Regression factor score predictors have the maximum factor score determinacy, i.e., the maximum correlation with the corresponding factor, but they do not have the same inter-correlations as the factors. As it might be useful to compute factor score predictors that have the same inter-correlations as the factors, correlation-preserving factor score ...

Materials & Design, 2022 The combination of biological scaffold and neural stem cells (NSCs) is a promising treatment strategy for spinal cord injury (SCI). But adverse niche at injures spinal cord severe hamper the transplanted NSCs to preferentially differentiate neurons.
