Effect of statin on long-term outcomes in persistent tobacco users receiving percutaneous coronary intervention: A longitudinal, retrospective cohort study.

The role of statins in improving cardiovascular outcomes is well established, but little is known about their impacts on long-term outcomes in persistent tobacco users with stable coronary artery disease (CAD) who receive percutaneous coronary intervention (PCI). A population of persistent smokers with CAD treated by PCI was analyzed. From 2012 through 2019, a cohort of 907 persistent tobacco users with stable CAD undergoing PCI were enrolled from the inpatient department of Taichung Tzu Chi Hospital, Taiwan.

Association between statin therapy and long-term clinical outcomes in patients with stable coronary disease undergoing percutaneous coronary intervention.

This longitudinal cohort study examined the long-term effect of statin therapy on clinical outcomes in patients undergoing percutaneous coronary intervention (PCI). A total of 1760 patients with stable coronary artery disease (CAD) were divided by receipt of statin therapy or not after index PCI. Baseline clinical characteristics, risk factors, angiographic findings, and medications after interventional procedure were assessed to compare long-term clinical outcomes between groups.

Effects of substrate and potassium on the betaine-synthesizing enzyme glycine sarcosine dimethylglycine N-methyltransferase from a halophilic methanoarchaeon Methanohalophilus portucalensis.

Methanohalophilus portucalensis FDF1 can synthesize the compatible solute betaine de novo through the methylation of glycine, sarcosine and dimethylglycine with the methyl group from S-adenosylmethionine. After separation by DEAE-Sephacel ion chromatography using a KCl step gradient, glycine, sarcosine and dimethylglycine methytransfer (GSDMT) activities were detected in a single peak. The estimated molecular weight of GSDMT was 240 kDa and 2-D gel analysis indicated it was separated into four subunits (52 kDa) with different pI.

Methanocalculus taiwanensis sp. nov., isolated from an estuarine environment.

Two novel hydrogenotrophic methanogens, designated strains P2F9704aT and P2F9705, were isolated from an estuary in Eriln Shi, Taiwan. The cells of strain P2F9704aT were non-motile, irregular cocci 0.9-1.
