Pseudouridine (Ψ) is the most abundant post-transcriptional RNA modification, yet little is known about its prevalence, mechanism and function in mRNA. Here, we performed quantitative MS analysis and show that Ψ is much more prevalent (Ψ/U ratio ∼0.2-0.6%) in mammalian mRNA than previously believed. We developed N3-CMC-enriched pseudouridine sequencing(More)
Seller reputation is recognized as an essential determinant in online C2C marketplaces, but its influence on price premium remains unknown. The majority of existing studies indicate that seller reputation is positively correlated with sales price (price premium) on eBay US, but not on Taobao China. Conversely, the strong correlation between seller(More)
To compare the performance of different commercial anti-dsDNA autoantibody assays, including multiplex-based immunoassay (Bio-Plex), Farr radioimmunoassay (Farr), ELISA, chemiluminescent immunoassay (CLIA), and Crithidia Luciliae indirect immunofluorescence test (CLIFT) in Chinese patients with systemic lupus erythematosus (SLE). SLE patients (n = 119) as(More)
BACKGROUND Clinical reports have shown that scopolamine produces a rapid (3-4 d) and potent anti-depressive response without severe adverse effects. Animal experiments have proven that scopolamine induces mTOR pathway activation in an AMPAR dependent manner. The present study aimed to determine the role of PKA in scopolamine-induced potentiation of AMPAR,(More)
Thrombotic microangiopathy (TMA) includes a series of life-threatening disorders. Systemic lupus erythematosus (SLE) is one of the most common acquired causes. To identify predictors of prognosis in patients with TMA secondary to SLE, we conducted a single-center historical study. From January 2013 to June 2016, of 2182 SLE hospitalized patients in the Ren(More)
RATIONALE, AIMS AND OBJECTIVES Acute fever is the most common early clinical symptom of many critical illnesses with a high mortality rate. It is necessary to identify patients with severe acute fever early and accurately. The aim of this study is to identify risk factors for critically ill outpatients with acute fever and formulate activation criteria of(More)
BACKGROUND/OBJECTIVES Angiotensin-converting enzyme 2 (ACE2), its product angiotensin-(1-7) and its receptor Mas may counteract the adverse effects of the ACE-angiotensin receptor II-AT(1) axis in many diseases. We examined the expression of these novel components of the rennin-angiotensin system in an experimental mouse model of severe acute pancreatitis(More)
BACKGROUND Many clinical trials had repeatedly shown that fast-track perioperative care and laparoscopic surgery are both preferred in the treatment of colorectal cancer. But few studies were designed to explore the diverse biochemical impacts of the two counterparts on human immunologic and nutritional status. METHODS Ninety-two cases of colorectal(More)
The elevated expression of urokinase-type plasminogen activator receptor (uPAR) is associated with the poor prognosis of pancreatic cancer patients. Thus, uPAR is a promising candidate as a molecular target for the non-invasive imaging of pancreatic cancer. The present study aimed to develop a technetium-99m (99mTc)-labeled uPAR-binding peptide for(More)
