With China's rapid economic development and urbanization process, cities are facing great challenges for tackling anthropogenic climate change. In this paper we present features, trajectories and driving forces for energy-related greenhouse gas (GHG) emissions from four Chinese mega-cities (Beijing, Tianjin, Shanghai and Chongqing) during 1995e2009. First,(More)
BACKGROUND Endoscopic submucosal dissection (ESD) enables en bloc resection of early gastrointestinal neoplasms; however, most ESD articles report small series, with short-term outcomes performed by multiple operators on single organ. We assessed short- and long-term treatment outcomes following ESD for early neoplasms throughout the gastrointestinal tract.(More)
Brain-derived neurotrophic factor (BDNF) activates its receptor TrkB, and promotes neuronal survival, differentiation, and synaptic functions. Furthermore, we have revealed that BDNF can also regulate cementoblast differentiation and cellular survival via TrkB-ERK/Akt signaling cascade, which, in turn, results in the induction of periodontal tissue(More)
BACKGROUND Runt-related transcription factor 3 (RUNX3) is a tumor suppressor of cancer and appears to be an important component of the transforming growth factor-beta (TGF-ss)-induced tumor suppression pathway. Surprisingly, we found that RUNX3 expression level in head and neck squamous cell carcinoma (HNSCC) tissues, which is one of the most common types(More)
As the aging of the population advances, the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and/or low-dose aspirin (LDA) is increasing. Their use is accompanied by a risk of serious complications, such as hemorrhage or perforation of the gastrointestinal tract. Therefore, gastroprotective strategies upon the prescription of NSAIDs/LDA are outlined in(More)
Prodigiosins are natural red pigments that have multi-biological activities. Recently, we discovered a marine bacterial strain, which produces a red pigment. Extensive two-dimensional nuclear magnetic resonance and mass spectrometry analysis showed that the pigment is a prodigiosin analogue (PG-L-1). Here, we investigated the effect of PG-L-1 on NADPH(More)
HIV infection induces phenotypic and functional changes to CD8+ T cells defined by the coordinated upregulation of a series of negative checkpoint receptors that eventually result in T cell exhaustion and failure to control viral replication. We report that effector CD8+ T cells during HIV infection in blood and SIV infection in lymphoid tissue exhibit(More)
LL37, an antimicrobial peptide, exhibits multiple bio-functions in various types of cells, including migration, cytokine production, apoptosis, and angiogenesis. Neovascularization and the subsequent recruitment of stem cells are essential for tissue engineering therapy, including bone regeneration. We hypothesized that LL37 can facilitate successful bone(More)
Brain-derived neurotrophic factor (BDNF) enhances periodontal tissue regeneration. Tissue regeneration is characterized by inflammation, which directs the quality of tissue repair. The objective of this study is to propose the relevance of BDNF to inflammation. In this study, we investigated the effect of BDNF on intercellular adhesion molecule (ICAM)-1,(More)
