Polycythemia vera (PV) is a human clonal hematological disorder. The molecular etiology of the disease has not been identified. PV hematopoietic progenitor cells exhibit hypersensitivity to growth factors and cytokines, suggesting possible abnormalities in protein-tyrosine kinases and phosphatases. By sequencing the entire coding regions of cDNAs of(More)
Interleukin (IL)-23, a new member of the IL-12 family, plays a central role in the Th17 immune response and in autoimmune diseases. It is clear that activated macrophages and dendritic cells produce IL-23, but the molecular mechanisms whereby inflammatory signals stimulate IL-23 expression are not fully understood. We demonstrate that induction of IL-23 p19(More)
A series of new bromophenols and chlorophenols were prepared by a practical route. The in vitro antioxidative activity of the halophenols was evaluated by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging assay, and their cytoprotective activity was also tested on hydrogen peroxide (H(2)O(2))-induced injury in human umbilical vein endothelial(More)
Recently, the JAK2(V617F) mutation was found in patients with myeloproliferative disorders (MPDs), including most with polycythemia vera (PV). The mutant JAK2 has increased kinase activity, and it was shown to be pathogenic in mouse models. Herein, we analyzed blood samples randomly collected from a clinical laboratory. Surprisingly, as many as 37 samples(More)
PURPOSE To evaluate the effects of lutein and zeaxanthin on visual function in randomized controlled trials (RCTs) of AMD patients. METHODS Relevant studies were identified by searches on PubMed, EMBASE, Web of Science, and Cochrane Library database up to April 2014. Three investigators independently determined the eligibility of RCTs, which compared(More)
T(H)17 cells are recognized as a unique subset of T helper cells that have critical roles in the pathogenesis of autoimmunity and tissue inflammation. Although RORγt is necessary for the generation of T(H)17 cells, the molecular mechanisms underlying the functional diversity of T(H)17 cells are not fully understood. Here we show that a member of interferon(More)
A series of long-chain derivatives of chrysin (compounds 3-22) were synthesized to evaluate for their antiproliferative activities against the human liver cancer cell line HT-29 and EGFR inhibitory activity. Among the compounds tested, compounds hexadecyl 2-(5-hydroxy-4-oxo-2-phenyl-4H-chromen-7-yloxy)acetate (10) and N-hexadecyl(More)
The explosive growth of Internet drives the development of high performance router. Applying distributed architecture, today's multi-shelf IP core router can provide flexible switch capacity from 1Tbps to 100Tbps. However, the more capacities it has, the more power it consumes, which is becoming a key barrier for bandwidth scaling. This paper studies the(More)
The JAK2(V617F) mutation was found in most patients with myeloproliferative disorders (MPDs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis. We have generated transgenic mice expressing the mutated enzyme in the hematopoietic system driven by a vav gene promoter. The mice are viable and fertile. One line of the transgenic(More)
Esophageal squamous cell carcinoma (ESCC) is one of the most common cancers worldwide and the fourth most lethal cancer in China. However, although genomic studies have identified some mutations associated with ESCC, we know little of the mutational processes responsible. To identify genome-wide mutational signatures, we performed either whole-genome(More)
