Phosphorylation of SPICK2, an AKT2 channel homologue from Samanea motor cells.

SPICK2, a homologue of the weakly-inward-rectifying Shaker-like Arabidopsis K channel, AKT2, is a candidate K+-influx channel participating in light- and clock-regulated leaf movements of the legume, Samanea saman. Light and the biological clock regulate the in situ K+-influx channel activity differentially in extensor and flexor halves of the pulvinus (the S. saman leaf motor organ), and also-though differently-the transcript level of SPICK2 in the pulvinus.

The behavior of follicle cysts formed after long-acting gonadotropin-releasing hormone analog administration in patients with polycystic ovarian syndrome.

This study was conducted to examine the effect of ovarian cysts that develop after administration of a gonadotropin-releasing hormone (GnRH) analog during an ovulation induction program for patients with polycystic ovarian syndrome. Twenty-eight women received Decapeptyl Continuous Release for 70 cycles starting on day 3 of the menstrual cycle, after exclusion of any ovarian pathology by transvaginal ultrasonography. Fifteen days later ultrasonography was again performed and serum estradiol estimated.

A follicular scoring system for monitoring ovulation induction in polycystic ovary syndrome patients based solely on ultrasonographic estimation of follicular development.

Objective: To assess the predictive value of a follicular scoring system for monitoring ovulation induction in polycystic ovary syndrome (PCOS) patients, solely with ultrasound (US).

Design: Ultrasound measurements were performed on alternate days to define a serial follicular score for monitoring ovulation induction with hMG alone, as well as GnRH analogue and hMG, in comparison with E2 concentration obtained on the same day.

Setting: Outpatient Infertility Clinic, Department of Obstetrics and Gynecology.

[Peak follicular estradiol (E2) levels and midluteal progesterone/E2 ratios in ongoing pregnancies and nonconception cycles after ovulation induced with gonadotropins].

We assessed the predictive value of peak follicular estradiol (E2) levels and progesterone/E2 ratios at the time of implantation (midluteal phase) in cycles resulting in pregnancies and in nonconception cycles after ovulation induced by hMG. hMG, administered to 31 consecutive patients with ovulatory dysfunction, resulted in 13 conception and 27 nonconception cycles. It was started on day 5 of the cycle and continued until at least 1 follicle was > 18 mm and E2 levels exceeded 300 pg/ml, when HCG, 100,000 IU, was administered.

Avoidance of cancellation of potential hyperstimulation cycles by conversion to in vitro fertilization-embryo transfer.

Objective: The study was undertaken to minimize the rate of ovarian hyperstimulation and to avoid cancellation of human treatment cycles in women treated with human menopausal gonadotropin (hMG) for induction of ovulation.

Setting: Patients were treated in the fertility clinic and in vitro fertilization unit of our institution, which is a government, university-affiliated hospital.

Patients: Ninety anovulatory patients were treated with hMG.
