A normal pattern of mitral inflow predicts a better prognosis following cardiovascular events in early advanced-age patients.

Although a mitral inflow pattern usually changes from a normal pattern to an abnormal relaxation pattern as part of the aging process in healthy people, some early advanced-age individuals maintain a normal pattern. We investigated whether a normal pattern of mitral inflow predicts a better prognosis following cardiovascular (CV) events in early advanced-age patients. We enrolled 425 patients aged 60-65 years with 0.

Novel assays to monitor gene expression and protein-protein interactions in rice using the bioluminescent protein, NanoLuc.

Luciferases have been widely utilized as sensitive reporters to monitor gene expression and protein-protein interactions. Compared to firefly luciferase (Fluc), a recently developed luciferase, Nanoluciferase (NanoLuc or Nluc), has several superior properties such as a smaller size and stronger luminescence activity. We compared the reporter properties of Nluc and Fluc in rice ().

Acute and chronic effects of mokuboito in a patient with heart failure due to severe aortic regurgitation.

Medical treatment for heart failure is still limited in patients with symptomatic aortic regurgitation (AR). Here we report the effects of mokuboito used in combination with standard medical therapy for heart failure in an inoperable patient with symptomatic severe AR. We observed acute effects of mokuboito in decreasing systemic vascular resistance and increasing cardiac output, as well as its chronic effects in improving New York Heart Association class, plasma brain natriuretic peptide levels, and left ventricular diastolic function.

A case of left ventricular aneurysm caused by localized myocardial infarction.

A 73-year-old man was hospitalized for unstable angina pectoris with no history of myocardial infarction. After undergoing percutaneous coronary intervention, left ventriculography incidentally revealed a cavity in the anterior wall, and echocardiography found the cavity wall to be dyskinetic. Myocardial contrast echocardiography revealed that the wall of the cavity was surrounded by myocardial tissue with low perfusion.

[Genotoxicity studies of stevia extract and steviol by the comet assay].

The genotoxicity of steviol, a metabolite of stevia extract, was evaluated for its genotoxic potential using the comet assay. In an in vitro study, steviol at 62.5, 125, 250, and 500 micrograms/ml did not damage the nuclear DNA of TK6 and WTK1 cells in the presence and absence of S9 mix.
