1. Introduction. Central nerve injuries generally lead to dysfunction and loss of neuronal tissue, resulting in long-term disabilities and major socio-economic costs. 1,2 The multipotent property of neural stem cells (NSCs), which can differentiate into neurons and glial cells, suggests that these cells are promising candidates for the treatment of Cited by: The tests revealed a correlation Defining fluoropolymer surfaces for enhanced nerve cell interaction.

Solid supports have been used as platforms for the photorelease of drug molecules. 1,2 However, there are gaps in data on whether Teflon-like 3,4 or superhydrophobic surfaces 5 can efficiently photorelease drugs. To address this issue, two photoactive fluoropolymers have been synthesized and compared (Figure 1).One is made of Cited by: The structural biology of membrane proteins has become an important focus of recent biochemical research.
With at least 30% of the human genome encoding for membrane proteins, they play a vital role in cell communication and most biological functions, yet their detailed structures remain poorly characterized. The efficacy of tetrodotoxin (TTX), a very potent local anesthetic, is limited by its poor penetration through barriers to axonal surfaces.
To address this issue, we encapsulated TTX in hollow silica nanoparticles (TTX-HSN) and injected them at the sciatic nerve in rats. TTX-HSN achieved an increased frequency of successful blocks, prolonged the duration of the block, Cited by: 3. The toxic effects of Ag nanoparticles (NPs) remain an issue of debate, where the respective contribution of the NPs themselves and of free Ag+ ions present in the NP stock suspensions and after intracellular NP corrosion are not fully understood.
Here, we employ a recently set up methodology based on high-content (HC) imaging combined with high-content gene Cited by: A water soluble polythiophene with tyrosine kinase inhibitor lapatinib as side chain moieties (PTL) was designed and synthesized.
