研究室紹介
Professor Hye-Jung Lee's research lab specializes in the design and synthesis of advanced functional materials, particularly nonlinear optical (NLO) molecules for applications in photonics and optoelectronics. The lab focuses on developing multiarmed organic molecules with strong charge-transfer characteristics, enabling applications in two-photon absorption and photorefractive effects. In addition, the lab conducts biomedical imaging research, utilizing advanced MRI techniques such as intravoxel incoherent motion (IVIM) and dual-energy CT to noninvasively assess tissue microstructure and fibrosis in cardiovascular and oncological diseases.

15Multiarmed nonlinear optical (NLO) molecules containing triphenylamine as a core and 4-(2-ethylhexylsulfonyl)benzene-(1E)-2-vinyl group or 4-{2-[4-(2-ethylhexylsulfonyl)phenyl]-(1E)-vinyl}benzene-(1E)-2-vinyl group as arms were synthesized (STEH series and SSEH series, respectively). Because triphenylamine linked to the sulfonylated stilbenic arms provided effective push−pull NLO structure and strong 2-D charge transfer, they were capable of both two-photon absorption (TPA) and photorefraction.
Purpose To evaluate the feasibility of equilibrium contrast material-enhanced dual-energy cardiac computed tomography (CT) to determine extracellular volume fraction (ECV) in nonischemic cardiomyopathy (CMP) compared with magnetic resonance (MR) imaging. Materials and Methods This study was approved by the institutional review board; informed consent was obtained. Seven healthy subjects and 23 patients (six with hypertrophic CMP, nine with dilated CMP, four with amyloidosis, and four with sarcoi
PURPOSE: We obtained intravoxel incoherent motion (IVIM) parameters through biexponential analysis on diffusion-weighted MR imaging (DWI) using multiple b values. Correlation was evaluated between these parameters and histological microvessel density (MVD) for the possibility of noninvasive evaluation of MVD with DWI. METHODS: Twenty-five nude mice with the HT29 colorectal cancer cells implanted were analyzed after undergoing DWI with multiple b values (0, 50, 100, 300, 500, 700, and 1000 s/mm(2
The prevalence of typical angina and that of MACE were significantly higher in patients with a high interarterial course than in those with a low interarterial course.
Sixty-four-slice CTCA is a noninvasive modality that allows quantification of coronary artery plaques. However, reliable classification of noncalcified plaques as vulnerable or stable plaques based on CT density measurements is currently limited.
Sebacic acid is an aliphatic ten-carbon dicarboxylic acid (1,10-decanedioic acid) with a variety of industrial applications. Here, we present its microbial production, purification, and polymerization.
Peptidylarginine deiminases (PADs) are enzymes that convert arginine to citrulline in proteins. In this study, we examined PAD-mediated citrullination and its effect on pro-inflammatory activity in the macrophage cell line RAW 264.7. Citrullination of 45-65-kDa proteins was induced when cells were treated with lipopolysaccharide (LPS; 1 μg/ml). Protein citrullination was suppressed by the intracellular calcium chelator BAPTA/AM (30 μM). LPS treatment up-regulated COX-2 levels in cells. Interesti
Schwann cells (SCs) in the peripheral nerves myelinate axons during postnatal development to allow saltatory conduction of nerve impulses. Well-organized structures of myelin sheathes are maintained throughout life unless nerves are insulted. After peripheral nerve injury, unidentified signals from injured nerves drive SC dedifferentiation into an immature state. Dedifferentiated SCs participate in axonal regeneration by producing neurotrophic factors and removing degenerating nerve debris. In t
LGE confined to the RVIP among NICM patients did not significantly increase the risk of adverse cardiac events, and also showed a better outcome than the same extent of LGE located in the LV. Identification of this unique LGE distribution may help refine the current risk stratification.
Aeromonas are widespread in aquatic environments and are considered emerging pathogens in humans and animals. Multidrug resistant (MDR) Aeromonas circulating in the aquatic environment and food production chain can potentially disseminate antimicrobial resistance (AMR) to humans via the foodborne route. In this study, we aimed to investigate AMR and virulence factors of 22 Aeromonas strains isolated from ready-to-eat (RTE) seafood. A multilocus phylogenetic analysis (MLPA) using the concatenated
Recent studies have demonstrated that TNF-related apoptosis-inducing ligand (TRAIL) is a modulator of the immune response. The relation between TRAIL and type 1 diabetes (T1D) as an autoimmune inflammatory disease in vivo is relatively unknown. To explore the potential role of TRAIL in the development of T1D, we examined its in vivo effects in nonobese diabetic (NOD) mice. NOD mice at 7 wk of age were iv injected with an adenovirus carrying either human TRAIL (Ad.hTRAIL) or β-galactosidase genes
