background: currently clomiphene citrate is the first-line treatment to induce ovulation in women with polycystic ovarian syndrome (pcos). surgical therapy with laparoscopic ovarian drilling (lod) may avoid or reduce the need for gonadotropins.   objective: to determine the effectiveness and safety of lod compared with ovulation induction in subfertile women with clomiphene-resistant pcos.   se...

background: so far, many studies investigated factors that affect pregnancy rates after intrauterine insemination (iui). various investigators have not agreed on the nature and ranking of these criteria. objective: the aim of this study was to assess the predictive factors for pregnancy rate after controlled ovarian hyperstimulation (coh)/ iui. materials and methods: retrospective study of all ...

background: human chorionic gonadotropin (hcg) has been used as a replacement for the mid-cycle luteinizing hormone (lh) surge for several years. the recent arrival of recombinant dna technology has made recombinant hcg (rhcg) accessible. objective: to assess efficacy of rhcg compared to urinary hcg (uhcg) for triggering of ovulation and induction of final oocyte maturation in assisted reproduc...

Electrical activity was recorded from the smooth muscle layer of the infundibulum of unanaesthetized hens during the ovulation cycle. There were low-frequency isolated spike potentials throughout the cycle except for the period near ovulation. There were intermittent bursts of spike potentials about 1 h before ovulation and then an increased frequency of spike potentials near the time of ovulat...

Exhumations of the victims of Franco's repressive policies are cultural practices of tremendous heuristic value and allow for the analysis of the public emergence, circulation and consumption of traumatic memory in local contexts. The use of visual media to capture social action in the surroundings of the exhumations serves as both a recording and as a triggering device for this emerging social...

Ovulation is critical for successful reproduction and correlates with ovarian cancer risk, yet genetic studies of ovulation have been limited. It has long been thought that the mechanism controlling ovulation is highly divergent due to speciation and fast evolution. Using genetic tools available in Drosophila, we now report that ovulation in Drosophila strongly resembles mammalian ovulation at ...

[1] Aftershocks follow a well‐defined spatial decay pattern in the intermediate field. Here I investigate the same pattern for foreshocks. Foreshock linear density decays as r over distances r of 0.1–30 km for 15 minutes before magnitude 3–4 mainshocks. This trend is the same as that of the aftershocks within the error of the measurement. This consistency of spatial decay can be explained by th...

We aimed to determine gene expression patterns in the anterior pituitary (AP) of heifers before and after ovulation via deep sequencing of the transcriptome (RNA-seq) to identify new genes and clarify important pathways. Heifers were slaughtered on the estrus day (pre-ovulation; n=5) or 3 days after ovulation (post-ovulation; n=5) for AP collection. We randomly selected 4 pre-ovulation and 4 po...
