BACKGROUND The Cox-Maze procedure (CMP) has achieved high success rates in the therapy of atrial fibrillation (AF) while becoming progressively less invasive. This report evaluates our experience with the CMP in the treatment of lone AF over 2 decades and compares the original cut-and-sew CMP-III to the ablation-assisted CMP-IV, which uses bipolar radiofrequency and cryoenergy to create the ori...

1. s-RNA nucleotidyltransferase incorporated CMP into phosphodiesterase-treated s-RNA more rapidly in the presence of Mg(2+) (10mm) than in the presence of Mn(2+) (2mm). UMP was incorporated more rapidly in the presence of Mn(2+), and at high ionic strength the incorporation of CMP was also more rapid in the presence of Mn(2+). 2. The capacity of phosphodiesterase-treated s-RNA for CMP, UMP and...

Sialic acids of cell surface glycoproteins and glycolipids play a pivotal role in the structure and function of animal tissues. The pattern of cell surface sialylation is species- and tissue-specific, is highly regulated during embryonic development, and changes with stages of differentiation. A prerequisite for the synthesis of sialylated glycoconjugates is the activated sugar-nucleotide cytid...

Silicon carbide (SiC) is widely used as a power semiconductor substrate material, even if it takes large amount of processing time to secure an appropriate surface wafer for devices after chemical mechanical polishing (CMP). Therefore, studies on SiC CMP have focused shortening the by increasing material removal efficiency. Among methods that been studied recently, photocatalysis-assisted (PCMP...

<p style='text-indent:20px;'>We consider a complex multi-objective programming problem (CMP). In order to establish the optimality conditions of (CMP), we introduce several properties optimal efficient solutions and scalarization techniques. Furthermore, certain parametric dual model is discussed, their duality theorems are proved.</p>

In this paper we explore the potential of reducing the cache size of the cores in the DDM-CMP architecture and implementing additional on-chip processors in the space saved. With this technique we almost double the already high speedup the DDM-CMP architecture has compared to a state-of-the-art high-end single chip microprocessor. The proposed DDM-CMP scheme achieves speedup ranging from 5.2 to...

CMP-Neu5Ac is an important sugar nucleotide for biosynthesis of sialic acid and its conjugates. In this paper, a large-scale production system of CMP-Neu5Ac by a single strain is reported. The co-expression of Neu5Ac aldolase (EC4.1.3.3) and CMPNeu5Ac synthetase (EC 2.7.7.43) was achieved by constructing individual genes into one plasmid and having a single culture that has both NeuAc aldolase ...

Cordyceps militaris (L.) Link is an entomopathogenic fungus parasitic to Lepidoptera larvae, and is widely used as a folk tonic or invigorant for longevity in China. Although C. militaris has been used in traditional Chinese medicine for millennia, there is still a lack convincing evidence for its anti-aging activities. This study was performed to investigate the effects of polysaccharides from...

We have established an efficient method for enzymatic production of cytidine 5'-monophospho-N-acetylneuraminic acid (CMP-NeuAc) from inexpensive materials, N-acetylglucosamine (GlcNAc) and cytidine 5'-monophosphate (CMP). The Haemophilus influenzae nanE gene encoding GlcNAc 6-phosphate (GlcNAc 6-P) 2-epimerase and the Campylobacter jejuni neuB1 gene encoding N-acetylneuraminic acid (NeuAc) synt...
