Delayed Drowsiness After Normobaric Hypoxia Training in an F/A-18 Hornet Simulator.

In military aviation, due to high-altitude flight operations, hypoxia training is mandatory and nowadays is mainly done as normobaric hypoxia training in flight simulators. During the last decade, scientific data has been published about delayed recovery after normobaric hypoxia, known as a "hypoxia hangover." Sopite syndrome is a symptom complex that develops as a result of exposure to real or apparent motion, and it is characterized by yawning, excessive drowsiness, lassitude, lethargy, mild depression, and a reduced ability to focus on an assigned task.

Comparison of buserelin and nafarelin in IVF cycles and in subsequent frozen-thawed embryo transfer cycles.

Objective: To compare two gonadotropin-releasing hormone agonists for down-regulation prior to superovulation in in vitro fertilization/embryo transfer treatment.

Methods: Infertility patients (n=181) were randomized to receive buserelin (1200 microg/day, n=90) or nafarelin (800 microg/day, n=91) intranasally starting in the luteal phase. Serum levels of LH, estradiol and progesterone were measured during the treatment.

Pattern and permanence of phosphate-induced nephrocalcinosis in rabbits.

Objective. The purpose of this study was to observe the pattern and permanence of phosphate-induced nephrocalcinosis (NC) in rabbits. Materials and methods.

Nephrocalcinosis in rabbits--correlation of ultrasound, computed tomography, pathology and renal function.

Objective. The purpose of this study was to induce nephrocalcinosis (NC) in rabbits with phosphate, vitamin D, oxalate and furosemide, to determine the effect on renal function and to correlate detection on ultrasound (US) and computed tomography (CT) with pathology. Materials and methods.

The effect of cryopreservation in prevention of ovarian hyperstimulation syndrome.

Objective: To evaluate the effect of elective cryopreservation of all embryos in the prevention of severe ovarian hyperstimulation syndrome in women at increased risk, following superovulation for in vitro fertilisation.

Design: Three hundred and ninety women undergoing superovulation for in vitro fertilisation between September 1991 and December 1992.

Setting: University Infertility Clinic, Helsinki, Finland.
