Chemokines, a group of small and structurally related proteins, mediate chemotaxis of various cell types via chemokine receptors. In mammals, seven different CXC chemokine receptors denoted as CXCR1 to CXCR7 have been reported. However, the chemokine receptor CXCR5 has not been reported in other vertebrates. In the present study, the genomic sequence of(More)
The emergence of wireless body area networks (WBAN) provides ubiquitous wireless communication services for users. But the characteristic of WBAN makes it inevitably suffer from many kinds of attacks, in order to ensure the safety of data (especially the user's privacy information) in transmission and storage. We propose an efficient and lightweight(More)
PTEN (phosphatase and tensin homolog deleted on chromosome 10) is a tumor suppressor and has been suggested recently to be involved in the regulation of cardiovascular diseases. The molecular mechanisms of this regulation are however poorly understood. This study shows that down regulation of PTEN expression and activity by angiotensin II (Ang II) increased(More)
Choriocarcinoma (CC) is the highest malignant gestational trophoblastic tumor which causes high mortality without timely treatment. HIF-1α is a very important molecule promoting neoplasm aggressiveness, metastasis through the induction of the epithelial to mesenchymal transition (EMT). Several researches have shown that Notch signaling is necessary for(More)
Blind signatures play a central role in applications such as e-cash and e-voting systems, while partially blind signature is an even more applicable variant. This paper proposes a Certificate less Partially Blind Signature (CPBS) by laying its construction on bilinear pairings over Gap Diffie-Hellman (GDH) Group for solving the key escrow problem in normal(More)
Gastric cancer (GC) is one of the most threatening diseases. The symptoms of GC are complex and hard to detect, which also contribute to the poor prognosis of GC. Besides, the current diagnosis for GC is expensive and invasive. Thus, a fast, noninvasive biomarker is urgently needed for GC screening. MicroRNAs (miRNAs) are small noncoding RNAs, which are(More)
Five new preussomerin analogues, ymf 1029A (1), B (2), C (3), D (4), and E (5), were isolated from the liquid cultures of an unidentified freshwater fungus YMF 1.01029, along with four known compounds, preussomerin C (6), preussomerin D (7), (4RS)-4,8-dihydroxy-3,4-dihydronaphthalen-1(2H)-one (8), and 4,6,8-trihydroxy-3,4-dihydronaphthalen-1(2H)-one (9).(More)
