Abstract: It is intended to provide a polynucleotide that is resistant to RNase and has an RNA interference effect, etc. The present invention provides a single-stranded polynucleotide that is derived from a double-stranded polynucleotide comprising a sense strand polynucleotide corresponding to a target gene, and an antisense strand polynucleotide having a nucleotide sequence complementary to the sense strand polynucleotide, and has a structure in which the 5?-end of the antisense strand and the 3?-end of the sense strand are linked via a phenyl group-containing linker to form a phosphodiester structure at each of these ends.

Abstract: An effective therapeutic agent for keloids and/or hypertrophic scars is provided. Specifically, an elastic fiber regenerating agent consisting of chondroitinase ABC derived from Proteus vulgaris and a therapeutic agent for keloids and/or hypertrophic scars comprising the regenerating agent as an active ingredient are provided.

Abstract: An electronic component has an element, a pair of terminal portions which are disposed on the element, and an external covering material which covers a part of the terminal portions and the element. The electronic component is configured such that inclined portions are disposed on corner portions of a bottom surface and side surfaces of the external covering material, and the terminal portions are protruded from corner portions where the inclined portions and the bottom surface of the external covering material intersect.

Abstract: The present invention aims to supply an electronic component which is manufactured in a manufacturing process at low cost, and realize improvement of shock resistance, endurance, flexure resistance, mounting reliability etc. at the same time, without requiring fine adjustment etc. The invention is an electronic component 1 which has an element 2, a pair of terminal portions 4 which were disposed on the element 2, and an external covering material 5 which covers the a part of the terminal portions 4 and the element 2, and configured in such a manner that inclined portions 10 are disposed on corner portions of a bottom surface 9 and side surfaces of the external covering material 5, and the terminal portions 4 are protruded from corner portions where the inclined portions 10 and the bottom surface 9 of the external covering material intersect.

Abstract: There is provided a food and drink having a reduced oil, fat, or sugar content yet retaining good gelation properties and good organoleptic properties, etc. A part of or the whole of gelation materials, low calorie sugars and/or oils and fats is/are replaced with polyfructan.
