As our fossil raw materials irrevocably diminish and environmental pressures build, a progressive changeover of chemical industries to renewable feedstocks emerges as an inevitable necessity. Experts realistically predict the end of cheap oil in 2040 at the latest, a development that we can already witness as chemical manufacturers confront the rising cost(More)
Long-time coherent integration technique is one of the most important methods for the improvement of radar detection ability of a weak maneuvering target, whereas the integration performance may be greatly influenced by the across range unit (ARU) and Doppler frequency migration (DFM) effects. In this paper, a novel representation known as Radon-fractional(More)
The core pluripotency factor Oct4 plays key roles in somatic cell reprogramming through transcriptional control. Here, we profile Oct4 occupancy, epigenetic changes, and gene expression in reprogramming. We find that Oct4 binds in a hierarchical manner to target sites with primed epigenetic modifications. Oct4 binding is temporally continuous and seldom(More)
This meta-analysis aimed to evaluate the efficacy of motion-preservation procedures to prevent the adjacent segment degeneration (ASDeg) or adjacent segment disease (ASDis) compared with fusion in lumbar spine. PubMed, Embase and the Cochrane Library were comprehensively searched and a meta-analysis was performed of all randomized controlled trials and well(More)
A Δ6-desaturase gene was isolated from Microula sikkimensis. Sequence analysis indicated that the gene, designated MsD6DES, had an open reading frame of 1,357 bp and encoded 448 amino acids. Heterologous expression in tobacco indicated that MsD6DES can use endogenous substrates to synthesize γ-linolenic acid (GLA, 18:3(Δ 6,9,12)) and octadecatetraenoic acid(More)
The incidence of the EGJA is rapidly increasing. The clinicopathological features have not yet been elucidated. The aim of this study was to analyze the differences in clinicopathological features and prognosis between patients with esophagogastric junctional adenocarcinoma (EGJA) and distal gastric adenocarcinoma (DGA).In this retrospective study, 1230(More)
Immune cells contribute to determining the prognosis of gastric cancer. However, their exact role is less clear. We determined the prognostic significance of different immune cells in intratumoral tissue (T), stromal tissue (S), and adjacent normal tissue (N) of 166 gastric cancer cases and their interactions, including CD3+, CD4+, CD8, CD57+, CD68+,(More)
