Nerve regeneration and function recovery remain challenges for tissue engineering. The application of suitable scaffold in tissue engineering has been demonstrated to be able to enhance nerve regeneration and differentiation. However, a desired scaffold must meet the requirements of good cytocompatibility and high electrical conductivity simultaneously. In this study, a conductive film composed of SF and graphene was successfully fabricated, which was applied to evaluate its effect on the neural differentiation of iPSCs. The conductive film was found to enhance the differentiation of iPSCs toward neurons. In addition, the differentiation was enhanced with graphene contents and highest value was obtained at graphene content of 4%. Thus, the results in this study suggested that 4% G/SF film might be a suitable biomaterial scaffold for application in neural regeneration. © 2018 Wiley Periodicals, Inc.

, a slow-growing nontuberculous mycobacterium, causes Buruli ulcer, a neglected tropical disease. Distinguishing from related species, including , poses challenges with respect to making accurate identifications. In this study, we developed a rapid and simple identification method based on mycobacterial lipid profiles and used matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) to analyze the lipid profiles of ( = 35) and ( = 19) isolates.

Background: Itch is a common clinical sign in skin disorders. While the neural pathways of itch transmission from the skin to the brain are well understood in rodents, the same pathways in dogs remain unclear. The knowledge gap hinders the development of effective treatments for canine itch-related disorders.

We hypothesize that the high gamma oscillations driven by L6CT neuron activation are shaped by the dynamic engagement of intracortical and cortico-thalamo-cortical circuits. To test this, we optogenetically activated L6CT neurons in NTSR1-cre mice expressing channelrhodopsin-2 in L6CT neurons.

In AD mouse models, non-invasive audiovisual stimulation (AuViS) at 40 Hz enhances gamma oscillations, clears amyloid-beta, and improves cognition. We investigated mechanisms of circuit remodeling underlying these restorative effects by leveraging the sensitivity of hippocampal neurogenesis to activity in middle-aged wild-type mice.

However, the consequence of reduced enzyme activity within neural cell sub-types remains ambiguous. Thus, the purpose of this study was to define the effect of GCase deficiency specifically in human astrocytes and test their non-cell autonomous influence upon dopaminergic neurons in a midbrain organoid model of PD.
