- Oxygen ions, with an energy of 70 keV, and doses ranging from 5×1013 to 5×1015 cm-2, were implanted into 6H SiC. The damage energies were calculated as 0.93-93 eV/atom with the doses respectively. The dielectric function obtained from spectroscopic ellipsometry were quite sensitive to ion irradiation of the surface, while the first order Raman spectroscopy decreased in intensity with increasing O+ ion dose. The damage behavior characterized by optical measurements was in good agreement with characterization by Rutherford backscattering spectrometry and channeling and atomic force microscopy.

- We examined the gene and protein expression of IRS 1 (insulin receptor substrate 1) in adipocytes from two groups of healthy individuals with an increased propensity for non-insulin-dependent diabetes mellitus (NIDDM): those with two first-degree relatives with diabetes and another group with massive obesity. A low expression of IRS 1 (

- OBJECTIVE: To compare the Auto CPAP Set system with standard polysomnography (PSG) in diagnosis and therapy of sleep breathing disorders. METHOD: Two studies were completed. The Auto CPAP Set system was compared with a simultaneously obtained PSG in eleven patients with sleep breathing disorders. Twenty-three additional patients with obstructive sleep apnea syndrome (OSAS) were treated by Auto CPAP Set. Student's t test was employed to evaluate statistical significance. RESULT: No differences were found between these two systems in AHI, SaO2 and the longest apnea duration (P > 0.05), and the Auto CPAP Set system had a sensitivity of 70% and a specificity 100% for diagnosis of OSAS. AHI decreased and SaO2 increased significantly in OSAS patients after treatment. CONCLUSION: The Auto CPAP Set system provides an accurate and simple method for diagnosis and therapy of sleep breathing disorders, and the time required for analysis of test results was shorter as compared with PSG.
