In this paper, a methodology to automate and standardize the identification of rainfall intensity–duration thresholds for landslides triggering is presented. A newly developed software called MaCumBA (MAssive CUMulative Brisk Analyzer) can be used to analyze rain-gauge records, extract the intensities (I) and durations (D) of the rainstorms associated with the initiation of landslides, plot the...

PURPOSE to establish whether there is a predictive relationship between the antral follicle count (AFC) on the second day of the cycle and the response pattern in controlled ovarian hyperstimulation cycles for intracytoplasmic sperm injection (ICSI). METHODS a prospective study developed from May 2004 to May 2005, in which 51 patients aged <37 years old were submitted to assisted reproduction...

Abstract Study question To explore whether prolonged hCG-ovum pickup(hCG-opu) interval improves assisted reproductive technology outcomes. Summary answer The clinical pregnancy rates can be increased by prolonging the hCG-opu interval, which would help develop more reasonable time schedules for fertility centers and patients. What is known already hCG-OPU greatly affects ART success, allows to ...

Ovarian hyperstimulation syndrome (OHSS) is one of the major complications in artificial reproductive technology, especially in high responders. Exogenous human chorionic gonadotropin (hCG) for triggering final oocyte maturation during controlled ovarian stimulation (COS) is primarily responsible for the pathogenesis of early-onset OHSS. Several strategies were offered to prevent OHSS, includin...

A 30-year-old primigravid (G1P000) female with infertility secondary to her partner's oligospermia and her chronic anovulation presented 13 days after an oocyte retrieval for in vitro fertilization (IVF) with a positive home pregnancy test, abdominal distention, a 5-pound weight gain, nausea, shortness of breath, and reduced urinary frequency. Her IVF cycle included the usual cocktail for gonad...

In stimulated IVF/intracytoplasmic sperm injection cycles, the luteal phase is disrupted, necessitating luteal-phase supplementation. The most plausible reason behind this is the ovarian multifollicular development obtained after ovarian stimulation, resulting in supraphysiological steroid concentrations and consecutive inhibition of LH secretion by the pituitary via negative feedback at the le...

Background During a normal menstrual cycle, progesterone prepares the endometrium for pregnancy by stimulating proliferation in response to human chorionic Gnadotropin produced by the corpus luteum. Many questions were raised about the role of follicular fluid aspiration on the granuloma cells at the time of oocyte retrieving during the ART cycles. Authors believes that oocyte retrieval might d...

STUDY QUESTION Can independent predictors of pregnancy-associated plasma protein-A (PAPP-A) levels be identified in a group of women who conceived following IVF/ICSI? SUMMARY ANSWER The significantly decreased PAPP-A level in IVF and ICSI pregnancies compared with non-IVF/ICSI pregnancies was correlated strongly with the serum estradiol (E2) level at ovulation triggering. WHAT IS KNOWN ALRE...
