Abstract: An electronic device is provided. The electronic device includes a housing, a driving circuit assembly, an adhesive layer, and a flexible circuit board. The driving circuit assembly is disposed on the housing. The adhesive layer is disposed between the housing and the driving circuit assembly. The adhesive layer includes an opening. The flexible circuit board is electrically connected to the driving circuit assembly. The flexible circuit board overlaps the opening. The housing and the driving circuit assembly are connected to each other by the first adhesive segment and the second adhesive segment.

Abstract: The invention provides a novel recombinant polypeptide that comprises a nucleic acid binding element and a hairpin motif that selectively binds to a neurotrophin receptor. The recombinant polypeptide may be used for neurotrophin receptor mediated delivery of nucleic acid, including therapeutic DNA, bound to the recombinant polypeptide. In one embodiment, the hairpin motif is a hairpin motif of a neurotrophin, such as nerve growth factor, brain derived neurotrophic factor, neurotrophin 3 and neurotrophin 4/5. The hairpin motif is also a neurotrophin agonist and therefore may be used to treat any disorder responsive to neurotrophin treatment, such as neurological disorders and tumour. In one embodiment the agonist comprises a hairpin motif that selectively binds to a neurotrophin receptor and a positively charged binding domain which is believed to enhance receptor binding by binding to negatively charged cell membrane.
