The molecular pathway regulating gastric carcinoma (GC) invasiveness and metastasis remains elusive. Here, we detected significant increase in the phosphorylated epidermal growth factor receptor (pEGFR), MMP7, and MMP13 in the resected GC, compared with the adjacent normal tissue, in patients. Moreover, strong positive correlation was detected between pEGFR(More)
We develop a model of international trade with export quality requirements and two dimensions of firm heterogeneity. In addition to “productivity”, firms are also heterogeneous in their “caliber” – the ability to produce quality using fewer fixed inputs. Compared to single-attribute models of firm heterogeneity emphasizing either productivity or the ability(More)
UNLABELLED This study aimed to explore biotinylated liposomes (BLPs) as novel carriers to enhance the oral delivery of insulin. Biotinylation was achieved by incorporating biotin-conjugated phospholipids into the liposome membranes. A significant hypoglycemic effect and enhanced absorption were observed after treating diabetic rats with the BLPs with a(More)
Light emitting diodes (LEDs) can be used as light detectors and as light emitters. In this paper, we present a novel BRDF measurement device consisting exclusively of LEDs. Our design can acquire BRDFs over a full hemisphere, or even a full sphere (for the bidirectional transmittance distribution function BTDF), and can also measure a (partial)(More)
Agrobacterium tumefaciens is a natural genetic engineer widely used to deliver DNA into various recipients, including plant, yeast and fungal cells. The bacterium can transfer single-stranded DNA molecules (T-DNAs) and bacterial virulence proteins, including VirE2. However, neither the DNA nor the protein molecules have ever been directly visualized after(More)
This paper is concerned with simultaneous stability of a collection of continuous-time linear plants whose feedback control loops are closed via a shared digital communication network. Because of the limitation of communication capacity, only a limited number of controller-plant connections can be accommodated at any time instant. Therefore, it is necessary(More)
The purpose of the study is to evaluate the 10 years follow-up of the efficacy in Chinese patients receiving cyclophosphamide, doxorubicin/epirubicin, vincristine, and prednisone (CHOP) or rituximab plus CHOP (R-CHOP) regimen as the initial treatment for diffuse large B cell lymphoma (DLBCL). We have retrospectively analyzed 437 patients with DLBCL who were(More)
Gastrointestinal diffuse large B cell lymphoma (DLBCL) is a common subtype of extranodal lymphoma. There has been uncertainty about the clinical efficacy of combination therapy (surgery and chemotherapy) for gastrointestinal DLBCL. We retrospectively analyzed 114 patients with newly diagnosed gastrointestinal DLBCL from six medical centers. We evaluated(More)
