Abstract

We report on the experimental results of a diode-pumped, intracavity-doubled cw Nd:YAG laser, pumped by a 10-W fiber-coupled semiconductor laser at 808 nm and emitting as much as 600 mW in a stable single longitudinal mode and [TEM.sub.00] spatial mode. We discuss the main issues of the resonator design and the optimization of the intracavity second harmonic conversion by interpreting our results using simple models. Improvements for the current project are also discussed.

25. GnRH analogs versus expectant management in minimal and mild endometriosis-associated infertility.

Abstract

The aim of the present study is to compare the outcome of GnRH analog treatment versus expectant management in infertile patients with minimal and mild endometriosis. From January 1987 to December 1990, 14 patients with stage I and II endometriosis underwent a six-month course of the GnRH analog buserelin, whereas 38 patients underwent expectant management. The two groups were comparable as to mean age of the patients, mean length of infertility prior to diagnosis and mean scores of endometriosis. No major tubal or male factor of infertility was present in any patient. Cumulative pregnancy rates at 12 months were comparable in the two groups (48% for GnRH analog treatment and 42% for expectant management). Expectant management should therefore be considered the most cost-effective option in the management of mild endometriosis-associated infertility.

Abstract

We examined the effects of an oral glucose load on plasma insulin, androgens, and beta-endorphin (beta EP) concentrations in patients carefully selected as having polycystic ovary syndrome (PCOS) and normal glucose tolerance. Our aim was to verify whether insulin resistance is a common feature of PCOS and to differentiate the metabolic abnormalities related to PCOS from those associated with obesity. Plasma immunoreactive insulin (IRI), C-peptide (C-PR), testosterone, androstenedione, dehydroepiandrosterone sulfate, ACTH, and beta EP responses to a 3-h oral glucose tolerance test (OGTT) were evaluated in 10 obese (OB-PCOS) and 10 nonobese (NO-PCOS) patients with PCOS and in 7 obese and 7 nonobese ovulatory controls. OB-PCOS and NO-PCOS did not differ significantly from weight-matched controls in the IRI response, but had a significantly higher C-PR response in terms of mean postglucose load levels and mean incremental areas. During OGTT, mean plasma levels of testosterone, androstenedione, and dehydroepiandrosterone sulfate declined in both PCOS groups as well as in controls, and no significant correlation between the plasma androgen and IRI or C-PR responses was found. The ACTH response in OB-PCOS and NO-PCOS was similar to that in controls, with a progressive decrease until 180 min. A similar decline in plasma beta EP was found in controls, whereas no change in plasma beta EP was observed in OB-PCOS and NO-PCOS. These findings indicate that independently of the presence of obesity, PCOS patients have enhanced insulin secretion in response to OGTT and show a peculiar pattern of changes in plasma beta EP.

Abstract

Abstract. CW diode-pumped laser operation of Nd[sup 3+] in Ca[sub 3]Sc[sub 2]Ge[sub 3]O[sub l2] (CaSGG) single garnet crystal has been demonstrated for the first time. We measured an 18% slope efficiency and 2.7-nm tunability with two different laser cavities. A spectroscopic characterization of our sample has also been performed including the absorption cross section in the 800-nm region and the emission cross section and radiative lifetime of the upper laser level.
