In this work, 0.08 mmol L(-1) of phthalic acid was introduced as a mobile phase additive to quantify free amino acids (AAs) by hydrophilic interaction liquid chromatography (HILIC) coupled with electrospray ionization tandem mass spectrometry (ESI-MS/MS). The addition of phthalic acid significantly increased the signal intensity of protonated AA ions,(More)
With the structure of Digital Signal Processor (DSP) application program getting more complex, there is a rise in the need for concurrent access to shared resources under a multitasking environment. However, the task scheduling and synchronization provided by most of the DSP operating systems is quite limited, which can barely meet the requirement of the(More)
BACKGROUND Colorectal cancer (CRC) is the third common cancer and the fourth leading cause of cancer death worldwide. A single nucleotide polymorphism (SNP), rs961253 located in 20p12, was firstly described to be associated with the increased risk of CRC in a genome-wide association study; however, more recent replication studies yielded controversial(More)
This study compared the assay results of HBV markers obtained with two automated immunoassay systems in serum samples with concomitant HBV antigens and antibodies. Eighty-nine samples of concomitant HBsAg and anti-HBs and 74 samples of concomitant HBeAg and anti-HBe were analyzed by the Abbott Architect i2000 and the Roche Elecsys 2010 immunoassay systems.(More)
OBJECTIVE This paper aims to assess the interaction between common variations in catalase (CAT) polymorphic gene and environmental factors for antioxidant defense enzyme in modulating individual susceptibility to colorectal cancer (CRC). METHODS A case-control study with 880 colorectal cancer cases and 848 controls was conducted to investigate whether(More)
In this paper we present a new method combining Mean Shift with Kalman filter for human tracking. Firstly, we use the Mean Shift algorithm based on color and texture features to calculate an accurate location in current frame. We select the HSV color space for calculating the histogram. Then Kalman filter is applied to predict the next initial searching(More)
Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related death worldwide due to latent liver disease, late diagnosis, and nonresponse to systemic treatments. Till now, surgical and/or biopsy specimens are still generally used as a gold standard by the clinicians for clinical decision-making. However, apart from their invasive(More)
BACKGROUND Uncovering the target gene of miR-584 to control thyroid carcinoma (TC) invasion and migration is of central importance in the diagnosis, treatment, and prognosis of TC. To validate whether miR-584 has a tumor-suppressive role in thyroid cancer cells by targeting ROCK1, a series of experiments were conducted to figure out the mechanism of action(More)
High iodine intake might be an important factor in the promotion of thyroid cancer and the incidence of thyroid carcinoma has increased obviously these years especially in area of high iodine intake, though the mechanism of which remains unknown. The aim of present study was to gain more insight into the influence of different iodine concentrations on cell(More)
