Seong-Yun Kim 교수의 연구실은 신경과학과 무기화학을 융합한 다학제적 연구를 수행합니다. 주로 뇌의 희소성 손상, 특히 혈관성 치매 모델에서의 미세교세포 활성화와 신경형성 변화를 다루며, 이와 관련된 약리적 조절(예: 미노시클린)과 생체 내 금속 이온(우라늄, 스트론티움 등)의 흡착 메커니즘을 연구합니다. 또한 신경염증 반응과 관련된 단백질(예: 올레오포린)의 발현 패atters를 분석함으로써 뇌 손상의 분자 기전을 규명하고자 합니다.

White matter lesions are thought to result from chronic cerebral ischemia and constitute a core pathology of subcortical vascular dementia. This rarefaction has been known to be associated with microglial activation. We investigated whether minocycline, a microglial inhibitor, attenuates the white matter damage induced by chronic cerebral hypoperfusion that is used as a model of vascular dementia. Male Wistar rats were subjected to bilateral, permanent occlusion of the common carotid arteries (B
The optimal cut-off values of SSTs needed to be individualized according to the type of SST and tested patient population.
A crown ether loaded resin was prepared by successive impregnation and fixing the 4′,4′(5″)-di(tert-butylcyclohexano)-18-crown-6 (DtBuCH18C6) and its molecule modifier, 1-dodecanol, onto the porous silica/polymer composite support (SiO2-P particles). The characterization of DtBuCH18C6 loaded resin was examined by thermal gravimetry and differential thermal analysis and electron probe microanalysis. The adsorption behavior of Sr(II), Cs(I), Ru(III), Pd(II), La(III), Nd(III), Sm(III), Gd(III), Zr(
Neurogenesis in the dentate gyrus occurs throughout life. We observed regional differences in neurogenesis in the dentate gyrus of adult rats following transient forebrain ischemia. Nine days after ischemic-reperfusion or sham manipulation, rats were given 5-bromo-2'-deoxyuridine-5'-monophosphate (BrdU), a marker for dividing cells. They were killed 1 or 28 days later to distinguish between cell proliferation and survival. Neurogenesis was evaluated by BrdU incorporation as well by identifying n
The present study was performed to investigate the spatial and temporal expression of osteopontin (OPN) mRNA in the rat brain after kainic acid-induced seizures, and to determine whether this phenomenon is associated spatiotemporally with the microglial reaction. The expression of OPN mRNA was detected using an in situ hybridization technique and Northern blot analysis. Following intraperitoneal injection of kainic acid (10 mg/kg), OPN mRNA was expressed in selective vulnerable areas, including
Abstract Electrochemical studies on [UO2(DMF)5]2+, UO2(acac)2DMF, and UO2(salen)DMF (DMF=N, N-dimethylformamide, acac=acethylacetonate, and salen=N,N′-disalicylidene-ethylenediaminate) complexes in DMF containing tetrabutylammonium perchlorate as supporting electrolyte have been carried out by using cyclic voltammetry to compare the stabilities of the reduction products of U(Vi) complexes with unidentate or multidentate ligands. The [UO2(DMF)5]2+, UO2(acac)2DMF, and UO2(salen)DMF complexes were
Paragangliomas rarely originate from the pancreas and they are characterized on imaging studies as well-marginated, hypervascular masses with cystic areas. We herein report on a case report of pancreatic paraganglioma in a 57-year-old woman, which was confirmed on pathology. Color Doppler ultrasonography and dynamic CT demonstrated a well-demarcated, extremely hypervascular mass with prominent intratumoral vessels and early contrast filling of the draining veins from the mass.
