https://www.selleckchem.com/products/GSK429286A.html Growth factors are required for cell proliferation and differentiation under physiological conditions but especially in the context of regenerative medicine. The time-prolonged administration of those factors has been explored using different sustained drug delivery systems. These platforms include natural materials such as bacterial inclusion bodies (IBs) that contain chaperones and other bacterial components that might favour protein release. Being successful from a functional point of view, IBs pose regulatory concerns to clinical applications because of the mentioned presence of bacterial cell components, including endotoxins. We have here explored the release and activity of the human fibroblast growth factor-2 (hFGF-2) from a novel synthetic material, namely artificial IBs. Being chemically homogenous and compliant with regulatory restrictions, we wondered if these materials would effectively release functional proteins in absence of accompanying bacterial agents. The data provided here fully supports that artificial hFGF-2 IBs act as true and efficient secretory granules and they slowly disintegrate in cell culture to promote wound healing in an in vitro wound healing model. Free from undesired bacterial components, artificial inclusion bodies show promises as delivery agents in regenerative medicine.Human action-stopping is thought to rely on a prefronto-basal ganglia-thalamocortical network, with right inferior frontal cortex (rIFC) posited to play a critical role in the early stage of implementation. Here we sought causal evidence for this idea in experiments involving healthy human participants. We first show that action-stopping is preceded by bursts of electroencephalographic activity in the beta band over prefrontal electrodes, putatively rIFC, and that the timing of these bursts correlates with the latency of stopping at a single-trial level earlier bursts are associated with faster stopping.
