Professor Jin Young Bae's research lab specializes in advanced materials and biomedical applications, focusing on the development of functional polymers for electronic packaging and photolithography, particularly in LCD technology and carbon black-based resist materials. The lab also conducts detailed neuroanatomical studies using immunohistochemical markers to characterize sensory neurons in the trigeminal system, contributing to a deeper understanding of peripheral nerve biology. Additionally, the lab explores biomarkers in cancer prognosis, particularly in cervical cancer, to improve clinical outcomes through early detection and personalized treatment strategies. These interdisciplinary efforts bridge materials science, neuroscience, and clinical medicine.

Substance P (SP), calcitonin gene-related peptide (CGRP), and isolectin B4 (IB4) are widely used as markers for peripheral neurons with unmyelinated fibers, whereas neurofilament 200 (NF200), and Peripherin are used as markers for neurons with myelinated fibers, and with unmyelinated or small-caliber fibers, respectively. To study the selectivity of these markers for specific neuronal types, we analyzed their expression in neurons in the rat trigeminal ganglion by light- and electron-microscopic
In stage IIICr cervical cancer, patients with PALNM, and/or pelvic side wall invasion can expect to have a poor prognosis. Particularly, pelvic side wall invasion in stage IIIC1r is an independent prognosis factor.
본 연구에서는 LCD 컬러필터 레지스트용 fluorene 단위 구조를 가지는 다기능 바인더 고분자를 개발하여 카본블랙 기반 감광성 레지스트(CBR)를 제조하고 블랙 매트릭스(BM)에 적용하였다. 다기능 바인더 고분자를 얻기 위해 bisphenol fluorene epoxy acrylate를 함유한 불포화 폴리에스터(BFEA-polyester)를 합성하였으며 이는 1H NMR, GPC 및 FTIR을 이용하여 분석하였다. 합성된 BFEA-polyester 바인더 고분자를 상업용 아크릴 바인더와 비교 평가하기 위하여 각각 CBR 제조 후 BM 리소그래피 테스트를 수행하였다. 그 결과, 본 연구에서 합성된 BFEA-polyester 바인더 고분자는 적합한 광경화 반응성과 알칼리 용해성을 가질 뿐만 아니라 기존 아크릴 바인더보다 더 우수한 공정 마진, 패턴 특성 및 유리 기판에 대한 접착력을 나타내었다.
Parvalbumin (PV), calretinin (CR), calbindin D-28k (CB), stage specific embryonic antigen-4 (SSEA4), and phosphorylated neurofilament 200 (pNF200) have been commonly used as markers for primary afferent neurons with large myelinated (A) fibers but detailed information on the expression of these markers in specific primary afferent fiber types is still lacking. We here examined the fibers that express PV, CR, CB, SSEA4, and pNF200 in the trigeminal ganglion and its peripheral sensory root by ligh
Thermotropic liquid crystalline polymers (LCPs) have been of great interest for electronic packaging. Herein, we introduce a series of wholly aromatic, thermotropic LCPs from copoly(ester amide)s of 6-hydroxy-2-naphthalic acid, isophthalic acid, terephthalic acid, and 4-aminophenol, prepared by a convenient one-pot melt polycondensation. Almost synthesized copoly(ester amide)s exhibited good solubility in common organic solvents at room temperature. Furthermore, they possessed high thermal stabi
Twin anemia-polycythemia sequence (TAPS) is characterized by a wide discrepancy of hemoglobin between two monochorionic fetuses without sign of twin oligo-polyhydramnios sequence. A primiparous woman with monochorionic diamniotic twin transferred for preterm labor. Ultrasonographic evaluation at 32+3 weeks of gestation revealed increased middle cerebral artery-peak systolic velocity (77.4 cm/sec, 1.69 multiples of median) in donor and decreased in recipient twin (36.4 cm/sec, 0.79 multiples of m
In 2011, the government of South Korea established a support program for obstetric care for underserved geographical areas to address the serious problem of the low birth rate. The birth rate of some underserved areas has since been increasing, and several indexes of mother and child health have since improved. However, various problems have also been noted in the evaluation of the policy for this support program. The birth rate of some rural areas remains low, and the inadequacy of professional
Fetal scalp cysts are rare, and they may be easily misdiagnosed as meningoceles or encephaloceles. A 38-year-old pregnant woman was referred to our hospital for ultrasound examination, which revealed a small cyst above the skull with no defect in the skull. The cyst could not be seen on follow-up ultrasound examinations. After delivery, a three-dimensional CT scan of the head revealed no defect in skull and scalp. Fetal scalp cysts usually require surgical excision after birth, but can regress w
revealed a fetal goiter. The maternal history and thyroid function tests, including antithyroid autoantibody tests, were unremarkable. Cesarean section was performed, and the thyroid profile of the neonate was consistent with congenital hypothyroidism. Thyroxine therapy was immediately started. Fetal thyroid function must be determined when a goiter is detected. Cordocentesis is a more reliable but riskier diagnostic tool than amniocentesis. Intra-amniotic injection of thyroxine is relatively sa
