Lymph node lymphatic vessels (LNLVs) serve as a conduit to drain antigens from peripheral tissues to within the lymph nodes. LNLV density is known to be positively regulated by vascular endothelial growth factors secreted by B cells, macrophages, and dendritic cells (DCs). Here, we show that LNLV formation was negatively regulated by T cells. In both steady(More)
Highly metastatic and chemotherapy-resistant properties of malignant melanomas stand as challenging barriers to successful treatment; yet, the mechanisms responsible for their aggressive characteristics are not fully defined. We show that a distinct population expressing CD133 (Prominin-1), which is highly enriched after administration of a chemotherapeutic(More)
The features and regulation of uterine angiogenesis and vascular remodelling during pregnancy are poorly defined. Here we show that dynamic and variable decidual angiogenesis (sprouting, intussusception and networking), and active vigorous vascular remodelling such as enlargement and elongation of 'vascular sinus folding' (VSF) and mural cell drop-out occur(More)
AIM To examine the reliability of Traditional Chinese Medicine (TCM) tongue inspection by evaluation of inter- and intrapractitioner agreement levels for specific tongue characteristics, achieved by a group of TCM practitioners. METHOD Ten (10) realistic tongue slides and a set of questionnaires were used to examine the agreement levels among 30 TCM(More)
Two vascular growth factor families, VEGF and the angiopoietins, play critical and coordinate roles in tumor progression and metastasis. A single inhibitor targeting both VEGF and angiopoietins is not available. Here, we developed a chimeric decoy receptor, namely double anti-angiogenic protein (DAAP), which can simultaneously bind VEGF-A and angiopoietins,(More)
OBJECTIVES When comparing the scores from Consumer Assessment of Health Plans Study (CAHPS) surveys across health plans, it is important to adjust for patient characteristics (casemix) that are not under the control of the plan but that affect plan ratings. Our goal was to develop casemix models for pediatric CAHPS surveys. METHODS We analyzed responses(More)
The angiopoietin/Tie (ANG/Tie) receptor system controls developmental and tumor angiogenesis, inflammatory vascular remodeling, and vessel leakage. ANG1 is a Tie2 agonist that promotes vascular stabilization in inflammation and sepsis, whereas ANG2 is a context-dependent Tie2 agonist or antagonist. A limited understanding of ANG signaling mechanisms and the(More)
Angiopoietin-2 (ANG2) regulates blood vessel remodeling in many pathological conditions through differential effects on Tie2 signaling. While ANG2 competes with ANG1 to inhibit Tie2, it can paradoxically also promote Tie2 phosphorylation (p-Tie2). A related paradox is that both inactivation and overactivation of Tie2 can result in vascular remodeling. Here,(More)
The aim of this study is to investigate whether mismatch negativity (MMN) is associated with functional status or is a state-independent trait for schizophrenia. We assessed MMN in 26 patients with schizophrenia, 20 healthy subjects with high genetic loading, and 48 healthy controls. Repeated measures analysis of variance and Pearson׳s correlations were(More)
We aimed to evaluate the prevalence of antineuronal antibodies in a nationwide cohort of patients with encephalopathy of unknown etiology. We screened 1699 patients with idiopathic encephalopathy who were referred from 70 hospitals across Korea for autoimmune synaptic and classic paraneoplastic antibodies. Those with cerebellar degeneration, sensory(More)
