Abstract: Disclosed is fucosyllactose having antiviral activity and inhibitory activity against viral infection, and a method for preventing or treating a viral infection by administering a composition including fucosyllactose as an active ingredient to a subject in need thereof. It was found that 2?-fucosyllactose and 3-fucosyllactose, which are human milk oligosaccharides (HMOs), have antiviral activity, and in particular, 3-fucosyllactose in vitro and in vivo exhibits much higher antiviral activity and inhibitory activity against viral infection compared to 2?-fucosyllactose and is thus useful as an antiviral agent.

Abstract: An electric field cancer treatment apparatus using a rotating alternating current (AC) electric field according to an embodiment of the present disclosure includes a plurality of electrode pairs configured to transmit AC electric fields to a target area in a body, a plurality of AC electric field generators respectively connected to the plurality of electrode pairs and configured to generate AC electric fields to be applied to the plurality of electrode pairs, and a controller configured to control generation of AC electric fields by the plurality of AC electric field generators.

Abstract: Proposed is a technology related to the ionization of silicon, and more particularly, to a technology for ionization by organizing silicon using a water-soluble silicate with a tricarboxylic acid or a dicarboxylic acid. This technology enables preparation and use of products containing an organized silicon ion complex in a variety of applications including foods such as water and beverages and medical products, as well as electrochemical applications. In particular, it is expected to treat and prevent various diseases caused by silicon deficiency by providing an organized form of silicon that does not exist as an ion in nature.

Abstract: A necktie having a series of interconnecting fasteners at its wide end and along its middle section, proximate to the wide end. The two cooperating fasteners at the wide end allow a wearer to fold this end of the tie up on itself, for a small hanging length reduction, relative to the length of the entire tie. The wearer may further shorten the hanging length by folding the wide end up to the middle section, where a third fastener connects to those of the wide end to secure the necktie in a folded formation that restricts it from interfering with the wearer's movement.
