The present study was designed to investigate whether arsenic trioxide induced the apoptosis in rat mesenteric arterial smooth muscle cells (SMCs), which provides new insights into mechanisms of arsenic-related vascular diseases. Here, we found that arsenic trioxide significantly decreased the viability of SMCs in a dose-dependent manner. In addition,(More)
This study was designed to assess the changes in nonlinear properties of heart rate (HR) variability (HRV) during the menstrual cycle by means of complexity measures, including sample entropy (SampEn) and correlation dimension (CD), and explore probable physiological interpretations for them. In 16 healthy women (mean age: 23.8 +/- 2.7 yr), complexity(More)
DNA sequencing by synthesis (SBS) on a solid surface during polymerase reaction offers a paradigm to decipher DNA sequences. We report here the construction of such a DNA sequencing system using molecular engineering approaches. In this approach, four nucleotides (A, C, G, T) are modified as reversible terminators by attaching a cleavable fluorophore to the(More)
DNA sequencing by synthesis during a polymerase reaction using laser-induced fluorescence detection is an approach that has a great potential to increase the throughput and data quality of DNA sequencing. We report the design and synthesis of a photocleavable fluorescent nucleoside triphosphate, one of the essential molecules required for the(More)
DNA sequencing by synthesis on a solid surface offers new paradigms to overcome limitations of electrophoresis-based sequencing methods. Here we report DNA sequencing by synthesis using photocleavable (PC) fluorescent nucleotides [dUTP-PC-4,4-difluoro-4-bora-3 alpha,4 alpha-diaza-s-indacene (Bodipy)-FL-510, dCTP-PC-Bodipy-650, and(More)
We report four-color DNA sequencing by synthesis (SBS) on a chip, using four photocleavable fluorescent nucleotide analogues (dGTP-PC-Bodipy-FL-510, dUTP-PC-R6G, dATP-PC-ROX, and dCTP-PC-Bodipy-650) (PC, photocleavable; Bodipy, 4,4-difluoro-4-bora-3alpha,4alpha-diaza-s-indacene; ROX, 6-carboxy-X-rhodamine; R6G, 6-carboxyrhodamine-6G). Each nucleotide(More)
We report here the design, synthesis and evaluation of a novel photocleavable (PC) biotinylated nucleotide analog, dUTP-PC-Biotin, for DNA polymerase extension reaction to isolate DNA products for mass spectrometry (MS) analysis. This nucleotide analog has a biotin moiety attached to the 5-position of 2'-deoxyribouridine 5'-triphosphate via a photocleavable(More)
The incidence of contrast-induced nephropathy has an increasing trend as a result of increased use of contrast media during coronary interventional procedures. Contrast-induced nephropathy is one of the major causes for hospital acquired renal failure after coronary interventional procedures. In this study, a total of 126 enrolled patients undergoing(More)
DNA sequencing by synthesis (SBS) offers an approach for potential high-throughput sequencing applications. In this method, the ability of an incoming nucleotide to act as a reversible terminator for a DNA polymerase reaction is an important requirement to unambiguously determine the identity of the incorporated nucleotide before the next nucleotide is(More)
High-throughput DNA sequencing development for mutation screening and identification is essential to realize the goal of pharmacogenomics and personalized medicine, which will lead to a new era in clinical medicine and healthcare. Molecular engineering approaches to modify the building blocks of DNA by introducing functional groups for purification and(More)
