    ..Our study indicates that vaspin prevents atherosclerotic plaque formation and instability, and may serve as a novel therapeutic target in atherosclerotic cardiovascular diseases. ..

    ..94). Sd LDL value was related to triglyceride, apoB, and LDL-cholesterol, but not to the buoyant LDL level. These results suggest that this precipitation method is a simple and rapid method for the measurement of sd LDL concentration. ..
  3. Yamamoto S, Hayashi T, Ohara M, Goto S, Sato J, Nagaike H, et al. Comparison of liraglutide plus basal insulin and basal-bolus insulin therapy (BBIT) for glycemic control, body weight stability, and treatment satisfaction in patients treated using BBIT for type 2 diabetes without severe insulin deficiency: A random. Diabetes Res Clin Pract. 2018;140:339-346 pubmed publisher
    ..Lira-basal therapy is superior to BBIT for T2DM without severe insulin deficiency. This study was registered with UMIN Clinical Trials Registry (UMIN000028313). ..

    ..Thus, adropin could serve as a novel therapeutic target in atherosclerosis and related diseases. ..

    ..We demonstrated for the first time that a DPP-4 inhibitor can substantially suppress plaque formation in coronary arteries with a marked reduction in macrophage accumulation likely via its anti-inflammatory properties. ..
  6. Hayashi T, Koba S, Ito Y, Hirano T. Method for estimating high sdLDL-C by measuring triglyceride and apolipoprotein B levels. Lipids Health Dis. 2017;16:21 pubmed publisher
    ..Similar results were obtained using the "alternative LDL window." Our proposed "LDL window" may help identify patients at high risk of CAD independent of LDL-C. ..

Dapagliflozin decreases small dense low-density lipoprotein-cholesterol and increases high-density lipoprotein 2-cholesterol in patients with type 2 diabetes: comparison with sitagliptin. Cardiovasc Diabetol. 2017;16:8 pubmed publisher
    ..However, these findings were not observed after treatment with dipeptidyl peptidase-4 inhibitor, sitagliptin. Trial registration UMIN Clinical Trials Registry (UMIN000020984). ..
