Abstract: Disclosed herein is a valve apparatus for vehicles that is configured such that the sealability of a valve body can be markedly enhanced. The valve apparatus includes a valve body, a valve member and a sealing unit. The valve body is provided with at least two ports and has an internal space communicating with the ports. The valve member is rotatably installed in the internal space so as to open or close the ports. The sealing unit is provided to seal at least one of the ports. The sealing unit includes a sealing body airtightly installed on an inner surface of the corresponding port, and at least one elastic element integrally provided on a first end of the sealing body. The elastic element axially applies elastic force to the sealing body so that a second end of the sealing body comes into airtight contact with the valve member.

Abstract: Disclosed are knottin peptides containing non-natural amino acids so that they can be formed by chemical conjugation into two or more knottin monomers. The knottin monomers comprise a non-natural amino acid such as an aminooxy residue within the polypeptide sequence. The exemplified dimers were produced by oxime formation between two aldehyde groups present on a polyether linker and an aminooxy functional group that was site-specifically incorporated the knottin. Knottins variants based on EETI (Ecballium elaterium trypsin inhibitor) and AgRP (Agouti-related protein) were engineered to contain integrin-binding loops. These dimers were shown to have increased binding strength to integrins on U87MG tumor cells, achieving significant increases in inhibition of cell adhesion and proliferation. Also disclosed are knottin monomers comprising an aminooxy residue; these may be conjugated to molecules such as doxorubicin.

Abstract: An air conditioner (AC) indoor unit includes a housing having an inlet and an outlet; a heat exchanger arranged inside the housing; a blower fan for sucking in air at the inlet to be subject to heat exchange with the heat exchanger, and discharging the heat-exchanged air out of the outlet; and an air flow control device for controlling an air flow discharged from the outlet by sucking in air around the outlet. The AC indoor unit may control the direction of a discharged air flow without a conventional blade structure, thereby increasing an amount of discharged air, reducing circulation noise, and enabling design differentiation.
