Pre-emption dimensional study aiming to obtain significant statistical results for the variation of serum cortisol during ovarian stimulation.

Unlabelled: Ovarian stimulation has an important place in the contemporary impressive development of infertility treatment. There are few and not concordant data concerning its influence on cortisol serum levels.

Aim: The present study aimed at finding the necessary number of determinations in order to statistically assess the variation of cortisol during and caused by the ovarian stimulation.

Preemption dimensional study for obtaining statistically significant results for the variation of gamma-glutamyl-transferase during ovarian stimulation.

Background: Ovarian stimulation with gonadotropins/ gonadotropin releasing factor agonists (a-GnRH), largely used currently for infertility treatment, can induce hepatic effects, demonstrated only in animals or in women with hyperstimulation syndrome.

Aim: We wanted to estimate the number of included patients for which the variation of gamma-glutamyl-transferase (GGT) during and due to ovarian stimulation could be sustained by statistic validation.

Method: In 23 consecutive patients, aged 23-45 years (mean 32.

Study of heart rate of professional divers in hyperbarism during simulated diving in saturation with different respiratory mixture.

Study of heart rate of professional divers in hyperbarism during simulated diving in saturation with different respiratory mixture. Study of heart rate of professional divers in hyperbarism (5.5 ATA and 20 ATA) during simulated divings and in saturation with different respiratory mixture (nitrox and heliox respectively) show a nonsignificant difference in bradycardia response.

Study of ejection fraction of professional divers during simulated diving in hyperbarism and various respiratory mixture.

This study was done to elucidate the influence of high pressure (5.5 and respectively 20.0 ATA) and various respiratory mixtures (nitrox and heliox) on cardiac output investigated (by the Ejection fraction) as in the medical literature there have not been found studies on the left ventricular performance of the divers under these conditions.
