Abstract: Provided herein are, inter alia, methods of assaying neuronal progenitor cell populations derived from iPSCs, thereby providing for a user friendly molecular diagnostic tool for neuronal cell types, including dopaminergic neurons. The methods provided are valuable for the efficient and precise characterization of identity and functionality of iPSC-derived dopaminergic neurons prior to their clinical application such as the treatment of Parkinson's disease or Multiple Sclerosis.

Abstract: The invention relates to a method for producing sandwich construction elements for substantially load-bearing and self-supporting building parts. In one embodiment of the invention, a method is provided including a) producing at least one layer of a mechanically bonded fiber nonwoven which is impregnated with a binder based on at least one heat-curable resin system b) curing the heat-curable resin system in order to produce at least one hardened layer of the fiber nonwoven, and fixed thermally, c) bringing a heat-foamable or heat-foamed phenol resin into contact with that surface of at least one hardened layer of the fiber nonwoven which has been modified according to step b), d) possibly annealing the composite produced in a) to c), and e) curing the further binder based on at least one heat-curable resin system.

Abstract: The invention relates to thermoset-bound fiber moldings produced from fiber material based on natural and/or synthetic fibers and bound by means of a thermoset binder. To produce thermoset-bound fiber moldings which combine the good mechanical, acoustical and fire properties of phenolic-bound fiber moldings with an ideally complete absence of any odor due to phenolic resin, at least one adsorbent is embedded in the surface and/or in the interior of the fiber molding during the operation of pre- and/or end-curing the thermosetting binder.
