Due to the widespread use of sophisticated imaging tools, digital image forgeries have already become a serious social problem. In this paper, we proposes an efficient and robust algorithm for detection of a specific category of digital image forgery known as region duplication forgery, which is done by copying a block of an image and pasting it on to some(More)
BACKGROUND In spite of recent advances in diagnostic and therapeutic measures, the prognosis of hepatocellular carcinoma (HCC) patients remains poor. Therefore, it is crucial to understand what factors are involved in promoting development of HCC. Evidence is accumulating that members of the chemokine receptor family are viewed as promising therapeutic(More)
Hyaluronic acid (HA) is a component of the Extra-cellular matrix (ECM), it is closely correlated with tumor cell growth, proliferation, metastasis and angiogenesis, etc. Hyaluronidase (HAase) is a HA-degrading endoglycosidase, levels of HAase are elevated in many cancers. Hyaluronidase-1 (HYAL1) is the major tumor-derived HAase. We previously demonstrated(More)
Thyroid hormones have been shown to regulate breast cancer cells growth, the absence or reduction of thyroid hormones in cells could provoke a proliferation arrest in G0-G1 or weak mitochondrial activity, which makes cells insensitive to therapies for cancers through transforming into low metabolism status. This biological phenomenon may help explain why(More)
OBJECTIVE To assess the prevalence of HIV infection and characteristically risk of factors which associated with HIV infection among MSM in Harbin, China. METHODS A face-to-face questionnaire interview was conducted among 463 Men Who Have Sex with Men (MSM) who were recruited by the snowball sampling in Harbin from April, 2011 to July, 2011. The(More)
Recent studies by use of short phosphopeptides showed that forkhead-associated (FHA) domains recognize pTXX(D/I/L) motifs. Solution structures and crystal structures of several different FHA domains and their complexes with short phosphopeptides have been reported by several groups. We now report the solution structure of the FHA domain of human Ki67, a(More)
In this paper, a novel image forensics method is proposed to detect manual blurred edges from a tampered image. Firstly, the image edges are analyzed by using non-subsampled contourlet transform. Then the differences between the normal edge and the blurred edge are extracted by researching phase congruency and prediction-error image. After that, the(More)
Proteins are molecules with different levels of repeated structures or patterns. These patterns are of great interest to biochemists since their identification can enhance the study of protein function. Though a lot of patterns have been found using ad-hoc methods, there is no systematic approach to find all the important structures in proteins. Here we try(More)
BACKGROUND RABEX-5, a guanine nucleotide exchange factor (GEF) for RAB-5, plays an important role in cell mobility and altered expression associated with tumor metastasis. This study aimed to investigate the role of RABEX-5 in proliferation and metastasis of breast cancer in vitro and ex vivo. METHODS RABEX-5 expression was examined in breast cancer,(More)
To explore the potential relationship between previous influenza virus (IV) infection and acute myocardial infarction (AMI), and the mechanism of atherosclerosis, we conducted a case–control study and examined inflammatory cytokines to assess the association of previous IV infection and AMI. A questionnaire-based survey was conducted to collect information(More)
