Abstract The Pim (proviral integration site for Moloney murine leukemia virus) proteins compose a serine threonine kinase family whose members regulate cell proliferation, migration and survival. However, whether kinases participate in innate immune responses is unclear. Here, we show the first time that Pim1 plays an essential role production of interferon (IFN)-β by macrophages after their Toll-like receptor (TLR) pathway activated pathogen-associated molecular patterns (PAMPs)....
2-Cyano-3,12-dioxo-oleana-1,9(11)-dien-28-oic acid methyl ester (CDDO-Me) is a triterpenoid analogue of oleanolic that exhibits promising anti-cancer, anti-inflammatory, antioxidant and neuroprotective activities. In addition, CDDO-Me affects cellular differentiation cell cycle arrest, irreversibly inhibits Lon protease-1 (LONP1). the present study, we evaluate effects on mitochondrial dynamics its downstream effectors in order to understand underlying mechanism neuronal death following...
Abstract Background and Aim Reliable bowel preparation assessment is important in colonoscopy. However, current scoring systems are limited by laborious time‐consuming tasks interobserver variability. We aimed to develop an artificial intelligence (AI) model assess cleanliness evaluate its clinical applicability. Methods A still image‐driven AI the Boston Bowel Preparation Scale (BBPS) was developed validated using 2361 colonoscopy images. For evaluating real‐world applicability, 113 10‐s...
Non-integrin 67-kDa laminin receptor (67LR) is involved in cell adherence to the basement membrane, and it regulates interactions between other receptors. The dysfunction of 67LR leads serum extravasation via blood-brain barrier (BBB) disruption. Polyphenol (–)-epigallocatechin-3-O-gallate (EGCG) pigment epithelium-derived factor (PEDF) bind inhibit neovascularization. Therefore, present study, we investigated effects EGCG NU335, a PEDF-derive peptide, on BBB integrity their possible...
4차 산업의 핵심인 인공지능(AI)기술은 빠른 속도로 진화하면서 최근 시각예술 분야에서도 급격한 발전을 보이고 있다. 본 논문은 멀티모달 인공지능(Multimodal AI)을 활용하여 만든 이미지 생성 AI 달리(DALL·E)를 중심으로 분야에서의 활용 사례를 알아보고 그 특징을 살펴보았다. 이론적 고찰로 분야에서 인공지능(AI)을 활용한 연구 동향과 꾸준히 성장하는 텍스트 기반 AI의 현황에 대하여 알아보았다. 이를 바탕으로 달리(DALL·E)의 살펴본 결과 첫째, 달리(DALL·E)는 디자이너와 예술가에게 상상의 이미지를 시각화 시켜주는 도구로 창의적 영감의 원천으로 활용될 수 둘째, AI는 기업의 광고나 마케팅, 홍보에 적용하여 상업적인 활용이 가능하다. 셋째, 다양한 분야의 디자인 산업에 기술이 활용되면 디자이너의 작업을 돕는 조력자로서 역할을 할 넷째, 예술가들에게 창작을 실현시키는 창의성을 실험할 기회를 제공할 있음을 확인하였다. 연구에서는 화두의 중심에 있는...
Objective To evaluate the effect of second-line conservative surgery on in vitro fertilization (IVF) outcome comparison with IVF without infertile women ovarian endometrioma recurrence after primary surgery. Methods In this retrospective cohort study, 121 consecutive IVF/intracytoplasmic sperm injection cycles that were performed (n=53) or (control group, n=68) between January 2006 and December 2011 endometrioma(s) for moderate to severe endometriosis included. The two groups compared terms...
Objective Nuclear factor kappa-B (NF-κB) is a critical proinflammatory regulator that has been suggested to play pivotal role in the pathogenesis and pathophysiology of endometriosis. In present study, we aimed evaluate whether expression NF-κB p65 subunit increased eutopic endometrium and/or adenomyosis nodule women with adenomyosis. Methods Thirty-three histologically confirmed after laparoscopic or transabdominal hysterectomy were recruited. Women carcinoma situ uterine cervix without...
Abstract Background/Aims Regression of liver fibrosis during antiviral therapy in chronic hepatitis B (CHB) patients has been demonstrated, but data on the influence long-term treatment with tenofovir disoproxil fumarate (TDF) stiffness (LS) measured by transient elastography are scarce. We aimed to investigate changes LS values 144-week TDF treatment-naïve CHB patients. Methods This prospective observational study was conducted from April 2015 July 2020 at CHA Bundang Medical Center....
Outer membrane vesicles (OMVs) are small enclosed sacs released from bacteria which serve as carriers of biomolecules that shape interactions with the surrounding environment. The periodontal pathogen, Porphyromonas gingivalis, is a prolific OMV producer. Here, we investigated how structure lipid A, core outer molecule, influences P. gingivalis production, OMV-dependent TLR4 activation, and biofilm formation. We examined mutant strains 33277 deficient for enzymes alter A phosphorylation...
Clasmatodendrosis is a kind of astroglial degeneration pattern which facilitates excessive autophagy. Although abnormal mitochondrial elongation relevant to this degeneration, the underlying mechanisms aberrant dynamics are still incompletely understood. Protein disulfide isomerase (PDI) an oxidoreductase in endoplasmic reticulum (ER). Since PDI expression downregulated clasmatodendritic astrocytes, may be involved astrocytes. In present study, 26% CA1 astrocytes showed chronic epilepsy...

4차 산업혁명을 기반으로 하는 첨단기술의 발전과 도심지 내 교통 혼잡을 해결하기 위한 대안으로 UAM이라는 새로운 도심항공교통 수단이 출현하였다. 국내에서도 관련법이 제정 · 공포되었고, 상용화를 준비가 이루어지고 있으나, 안전성과 관련된 입법이 미흡한 실정이다. UAM 상용화에 앞서 안전성 담보를 가장 우선적으로 고려해야 한다는 사실에는 이견이 없을 것이다. 그러나 국내 현행법상 안전기준과 조항이 미비하고 포괄적인 입법으로 인해 세부적인 지침 마련 및 개정이 불가피할 것으로 보인다. 따라서 본고에서는 선제적인 입법을 단행하고 있는 국외의 국가들을 중심으로 국내법과의 비교 검토를 통해 시사점 개선 방안을 제시하였다. 먼저 혼재되어 관련 용어의 정의 개념을 정립한 후 인증 체계를 확립하였다. 또한 법률의 개정안을 제시함으로써 향후 발전에 기여하고자 하였다.
본 연구는 청소년이 학교를 그만두는 복합적, 근본적 사유가 무엇이었는지, 그 과정에서 주변인과 어떤 상호작용을 하였는지 심층적으로 이해하고, 이를 토대로 학업중단 예방 정책에의 시사점을 도출하기 위한 목적을 지닌다. 위해 학교 밖 청소년 10명을 대상으로 질적 사례 연구를 수행하였고, FGI를 통해 자료를 수집하였다. 연구 결과 학업중단의 심층적 사유로서 세 가지 유형이 도출되었다. ‘진로 유형’에서는 고등학교 진학과정에서의 고민, 특성화고등학교 부적응, 전편입학 절차의 어려움의 경험을, ‘학업 대학입시에 대한 부담, 자유로운 시간과 경험 추구를, ‘관계 영역’에서는 친구 및 교사와의 갈등 경험을 생생하게 드러냈다. 주변인 중 특히 상담(교)사와의 상호작용이 보호 역할을 하였으며, 위클래스와 대안교실은 ‘쉼과 완충지’의 공간이라는 의미를 지니고 있었다. 학업중단숙려제를 신청하는 단계에서 이미 자퇴의 결심이 확고한 경우가 많아, 조기대응의 필요성을 시사했다. 결과를 다음과 같이...
