Atmospheric scanning electron microscopy and its applications for biological specimens.

Scanning electron microscopy in ambient conditions (Air-SEM) was developed recently and has been used mainly for industrial applications. We assessed the potential application of Air-SEM for the analysis of biological tissues by using rat brain, kidney, human tooth, and bone. Hard tissues prepared by grinding and frozen sections were observed.

Anomalous origin of the left circumflex coronary artery from the first diagonal branch presented as acute myocardial infarction.

Coronary artery anomalies are diagnosed in 0.6 to 1.5% of patients who undergo coronary angiography (CAG).

Reference values for the augmentation index and pulse pressure in apparently healthy korean subjects.

Background And Objectives: Arterial stiffness is a precursor to premature cardiovascular disease. The augmentation index (AI) and pulse pressure (PP) are cardiovascular risk factors. The aim of this study was to define the diagnostic values of the AI and PP from the peripheral arterial and central aortic waveforms in healthy subjects.
