A surface-acoustic-wave (SAW) gas sensor with a low detection limit and fast response for volatile organic compounds (VOCs) based on the condensate-adsorption effect detection is developed. In this sensor a gas chromatography (GC) column acts as the separator element and a dual-resonator oscillator acts as the detector element. Regarding the surface(More)
AIM Excessive production of inflammatory mediators during invasive infection plays a key role in the pathogenesis of sepsis. In an attempt to improve survival of patients with this lethal syndrome, agents were developed to selectively inhibit mediators in this inflammatory response. Ulinastatin (UTI), a human protease inhibitor, inhibits the enhanced(More)
OBJECTIVE The present study was designed to examine the changes of MMP-2/TIMP-2 in the hearts of streptozotocin-induced diabetic rats and gain insight into their roles in extracellular matrix (ECM) remodelling on an experimental animal model of diabetic cardiomyopathy. METHODS AND RESULTS Sixteen male Wistar rats were randomly divided into two groups:(More)
Panax notoginseng (Burk.) F.H. Chen is one of the most highly valued medicinal plants in the world. The major bioactive molecules are triterpene saponins, which are also known as ginsenosides. However, its large genome size has hindered the assembly of a draft genome by whole genome sequencing. Hence, genomic and transcriptomic details about P. notoginseng,(More)
ΔNp63α is a member of the p53 family of transcription factors that functions as an oncogene in squamous cell carcinomas (SCCs). Because ΔNp63α and p53 bind virtually identical DNA sequence motifs, it has been proposed that ΔNp63α functions as a dominant-negative inhibitor of p53 to promote proliferation and block apoptosis. However, most SCCs concurrently(More)
BACKGROUND Excessive deposition of extracellular matrix (ECM) in the kidney is the hallmark of diabetic nephropathy. Increased matrix synthesis has been well documented but the effects of diabetes on degradative pathways, particularly in the in vivo setting. The renal protective effect of these pathways on matrix accumulation has not been fully elucidated.(More)
Using " A " shares accessible only to local investors (who account for 99% of stock investors in China), this paper tests if short-horizon contrarian and intermediate-horizon investment strategies generate abnormal profits. We find statistically significant abnormal profits for both the arbitrage portfolio-investment strategies. Detailed analysis indicates(More)
Frontispiece: A covalent triazine-based framework (CTF) possessing a graphene-like layered morphology demonstrates excellent photocatalytic activity and stability in splitting water under visible light irradiation. Due to the tailorable electronic and spatial structures of CTFs, they not only show great potential as organic semiconductors for photocatalysis(More)
Water environment system is a complex system, and an agent-based model presents an effective approach that has been implemented in water resource management research. Urban water resource optimal allocation is a challenging and critical issue in water environment systems, which belongs to the resource optimal allocation problem. In this paper, a novel(More)
