Fourier Transform Spectroscopy of the Y2Sigma+-X2Pii Transition of CuO.

The Y2Sigma+-X2Pii near-infrared electronic transition of CuO was observed at high resolution for the first time. The spectrum was recorded with the Fourier transform spectrometer associated with the McMath-Pierce Solar Telescope at Kitt Peak. The excited CuO molecules were produced in a low pressure copper hollow cathode sputter with a slow flow of oxygen.

[Biochemical findings in osteoporosis. II. The importance of zinc].

The authors examined 33 cases of senile, 18 cases of postmenopausal and 9 cases of medicamentous osteoporosis and assessed serum and red cell zinc content. The mean blood levels of zinc were highest in the group of medicamentous osteoporosis. In all three groups the zinc level was reduced more frequently in serum than in red cells.

[Biochemical findings in osteoporosis. I. The significance of magnesium].

The authors examined in 60 patients with osteoporosis the serum and red cell magnesium and calcium content. Thirty-three patients suffered from senile osteoporosis, 18 patients from postmenopausal osteoporosis and nine had osteoporosis caused by corticoids. In the former two groups were signs of chronic magnesium deficiency, in the third groups there was a trend of low serum calcium levels.
