Abstract: Disclosed are an inductor layout and an integrated circuit device with improved isolation between inductors through shielding magnetic coupling between the inductors. first and second inductor coils are horizontally spaced apart from each other. A conductor loop is disposed in parallel above the first inductor coil and shields magnetic coupling between the first and second inductor coils in the manner that a part of magnetic flux of a first time-varying magnetic field generated by the second inductor coil is cancelled by magnetic flux of a second magnetic field generated by an induction current that flows in the conductor loop magnetically interlinked with the first time-varying magnetic field. The inductor layout can be applied to an RFIC device to reduce magnetic coupling between inductors of a power amplifier and an oscillator. Improved performance of the device and a very small RFIC can be achieved.

Abstract: The present invention relates to an induced pluripotent stem cell model of Fabry disease, a preparation method thereof, and a use of the same for the study of Fabry disease development and for the screening of a therapeutic agent for the disease. Particularly, Fabry disease derived induced pluripotent stem cells (iPSCs), embryoid body (EB), and vascular cells were developed and differentiated from fibroblasts originated from Fabry disease patient, wherein the Fabry disease originated iPSCs displayed significantly reduced expression and activity of GLA protein therein, compared with the normal cells, resulting in the accumulation of globotriaosylceramide (Gb3, CD77). Also, the differentiation of vascular cells was induced from the Fabry disease originated iPSCs, and as a result the iPSCs were successfully differentiated into vascular endothelial cells and vascular smooth muscle cells with significantly expressing the marker protein. When the vascular endothelial cells and vascular smooth muscle cells were treated with Fabrazyme, the accumulation of Gb3 was significantly reduced, suggesting that the said cell model can be effectively used for the analysis/study of Fabry disease outbreak mechanism and for the screening of a therapeutic agent for the disease.

Abstract: The present invention relates to novel polypeptide for binding to a complement protein C5a. More particularly, the present invention relates to polypeptide which can be bound to a complement protein C5a and inhibit the activation of same, polynucleotide which codes for the polypeptide, a recombinant vector which comprises the polynucleotide, a recombinant microorganism to which the recombinant vector has been introduced, a method for producing the polypeptide by means of the recombinant microorganism, and a pharmaceutical composition, for treating immune diseases or sepsis, containing the polypeptide. A polypeptide, according to the present invention, can be bound to a complement protein C5a, with higher affinity compared to being bound to a complement protein C5a receptor which is present in nature, and inhibits the activation of same, thus being widely utilized for development of formulation for preventing or treating diseases related to a complement protein C5a.

Thus, the hetero nanoparticle catalysts are uniformly fastened to an inside and a surface of one-dimensional metal oxide nanofibers to form a member for a gas sensor. As a result, the member for a gas sensor has a high-sensitivity characteristic capable of sensing a very small amount of a gas and excellent selectivity capable of sensing various gases. In addition, a catalyst effect is maximized by the hetero nanoparticle catalysts uniformly distributed without aggregation. Furthermore, the member for a gas sensor and the gas sensor using the same can be mass-produced by a process method capable of effectively forming pores and of fastening high-performance catalysts.
