This paper presents an adaptive predistortion RF power amplifier for repeater systems with a spectrum monitor. For adaptive control of cancellation, we implement a spectrum monitor that improves the adjacent channel leakage ratio (ACLR) characteristics of the power amplifier by analyzing the output spectrums of RF power amplifiers directly and(More)
Classical swine fever virus (CSFV) causes a highly contagious disease among swine that has an important economic impact worldwide. CSFV strain LOM is an attenuated virus of low virulent strain of Miyagi isolated from Japan in 1956. Eight DNA fragments representing the genome of the CSFV strain LOM were obtained by RT-PCR. These were used to determine the(More)
Replication of the hepatitis B virus is suppressed by deficiency of the X protein. Although several molecules that block cellular targets of X protein reduce the production of hepatitis B virus progeny, the effect of a specific inhibitor of X protein on viral replication has not been investigated. To block X protein specifically, we adopted an intracellular(More)
Aldosterone synthase plays an important role in determining the levels of aldosterone secretion. Polymorphisms of the aldosterone synthase gene (CYP11B2) are suggested to be associated with essential hypertension. In this study, we examined associations of CYP11B2 polymorphisms [−344T/C, K173R and intron 2 conversion (IC)] with Korean hypertensive patients.(More)
BACKGROUND T cell immunoglobulin and mucin domain containing 3 protein (Tim-3) expressed on terminally differentiated Th1 cells plays a suppressive role in Th1-mediated immune responses. Recently, it has been shown that N-glycosylation affects the binding activity of the Tim-3-Ig fusion protein to its ligand, galectin-9, but the binding properties of(More)
Apolipoprotein C3 (ApoC3) plays a regulatory role in triglyceride (TG) metabolism. The higher level of TG can be a cause in pathogenesis of the vascular diseases or metabolic syndrome (MetS). In this study, we examined the associations of ApoC3 polymorphisms (−482C>T rs2854117 and 3238G>C rs5128) with Korean MetS patients. A total of 835 subjects were(More)
Apolipoprotein A1 (ApoA1) plays an important role in reverse cholesterol transport. The functional abnormality of ApoA1 is known to be the major risk for lipid disorders or cardiovascular diseases. In this study, we examined the associations of two ApoA1 polymorphisms (XmnI and MspI/rs670) with the Korean patients with metabolic syndrome (MetS). A total of(More)
Vascular endothelial growth factor (VEGF) is one of the most potent angiogenic factors. VEGF plasma levels have been reported to be significantly elevated in the patients with hypertension. This study aims to elucidate the associations of the VEGF −634G>C and 936C>T polymorphisms with the hypertensive patients in Korea. Genotyping of the VEGF polymorphisms(More)
Background: Members belonging to the interferon-lambda (IFN-λ) family exert protective action against viral infection; however, the mechanisms of their action have remained elusive. To study IFN-λ biology, such as endocytosis of IFN-λ, we produced monoclonal antibodies (Abs) against human IFN-λ and examined their usefulness. Methods: We purified recombinant(More)
