Effect of Tai Chi training on baroreflex sensitivity and heart rate variability in patients with coronary heart disease.

Tai Chi is a traditional Chinese conditioning exercise that has been used to integrate slow movements, controlled breathing, and mental concentration. The aim of the study was to determine whether Tai Chi training in addition to cardiac rehabilitation would result in a shift toward increased vagal activity of autonomic markers, such as baroreflex sensitivity (BRS) and heart rate variability (HRV). Twenty patients with coronary heart disease (CHD) (male/female: 13/7, mean age: 67.

[Construction of urinary Tamm-Horsfall protein assay by enzyme-linked immunosorbent assay and establishment of reference range of healthy subject].

Tamm-Horsfall protein (THP) is the most abundant protein in the urine. THP is expressed in the renal tubule as a precursor protein having 640 amino acid residues and anchored by GPI anchor in the cell membrane. Thereafter, THP is secreted as a glycoprotein is a molecular weight of about 95-100 kD.

Cellular responses of the ciliate, Tetrahymena thermophila, to far infrared irradiation.

Infrared rays from sunlight permeate the earth's atmosphere, yet little is known about their interactions with living organisms. To learn whether they affect cell structure and function, we tested the ciliated protozoan, Tetrahymena thermophila. These unicellular eukaryotes aggregate in swarms near the surface of freshwater habitats, where direct and diffuse solar radiation impinge upon the water-air interface.
