BACKGROUND Congenital heart defects (CHD) are the most common form of malformation during embryonic development. Circulating miRNAs have recently been shown to serve as diagnostic/prognostic biomarkers in patients with cancers. Our current study focused on the altered expression of maternal serum miRNAs and their correlation with fetal CHD. (More)
Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide and is closely associated with metabolic syndromes, such as obesity, diabetes, and insulin resistance. Nonalcoholic fatty liver (NAFL), also called simple steatosis, is the initial phase of NAFLD, which is accompanied the characteristic pathological(More)
This paper explores a context-aware and personalization method in Mobile Learning system based on ubiquitous learning logs. Ubiquitous learning log stands for the log of knowledge or learning experience acquired ubiquitously. We construct a ubiquitous learning log system called SCROLL (System for Capturing and Reminding of Learning Log). Our research(More)
In this work, we fabricated polymeric fibrous scaffolds for bone tissue engineering using primary human osteoblasts (HOB) as the model cell. By employing one simple approach, electrospinning, we produced poly(lactic-co-glycolic acid) (PLGA) scaffolds with different topographies including microspheres, beaded fibers, and uniform fibers, as well as the(More)
Repackaged malware and phishing malware consist 86% [35] of all Android malware, and they significantly affect the Android ecosystem. Previous work use disassembled Dalvik bytecode and hashing approaches to detect repackaged malware, but these approaches are vulnerable to obfuscation attacks and they demand large computational resources on mobile devices.(More)
Biomass burning covers open fires (forest and grassland fires, crop residue burning in fields, etc.) and biofuel combustion (crop residues and wood, etc., used as fuel). As a large agricultural country, China may produce large quantities of mercury emissions from biomass burning. A new mercury emission inventory in China is needed because previous studies(More)
BACKGROUND Few data are available on the attributable burden, such as absolute excess or relative excess, of stroke death due to temperature. METHODS We collected data on daily temperature and stroke mortality from 16 large Chinese cities during 2007-2013. First, we applied a distributed lag non-linear model to estimate the city-/age-/gender-specific(More)
ADP-ribosylation factors (ARFs) have been widely identified as being involved in regulation of cell differentiation, intracellular vesicle transport, and cytoskeleton organization in animals and plants. To systematically clarify the ARF gene family in rice, eight putative rice ARF genes (OsARFs) were detected by searching the rice genome database. The(More)
Few multi-city studies have been conducted to investigate the acute health effects of low and high temperatures on diabetes mortality worldwide. We aimed to examine effects of ambient temperatures on city-/gender-/age-/education-specific diabetes mortality in nine Chinese cities using a two-stage analysis. Distributed lag non-linear model was first applied(More)
