Spatial periodicity in the cochlea: the result of interaction of spontaneous emissions?

In this study the results of simulations with a nonlinear macromechanical model of the human cochlea are presented. In this model it is possible to investigate the interactions between large numbers of spontaneous emissions. The focus of this study is on the effect of a local maximum in emission strength on its direct surroundings.

Is 1 mg of estradiol valerate or 0.625 mg of conjugated estrogens sufficient for all women to prevent menopausal bone loss?

Bone mineral content was measured by dual photon absorptiometry in 35 women who needed estrogen replacement therapy but did not want the addition of progestogens because they did not want regular bleeding. A total of 23 women were treated with estradiol valerate 1 mg per day over a mean period of 3.7 years; 12 women received conjugated estrogens 0.

Urinary fluoride excretion in responders and nonresponders after fluoride therapy in osteoporosis.

The aim of the study was to investigate the usefulness of urinary fluoride excretion in evaluating fluoride therapy. In a prospective study, 35 patients with osteoporosis were treated for about 44 months with a mean dosage of 31.4 mg fluoride ion per day.
