The structure of the blue whirl revealed.

The blue whirl is a small, stable, spinning blue flame that evolved spontaneously in recent laboratory experiments while studying turbulent, sooty fire whirls. It burns a range of different liquid hydrocarbon fuels cleanly with no soot production, presenting a previously unknown potential way for low-emission combustion. Here, we use numerical simulations to present the flame and flow structure of the blue whirl.

Toolbox for the design of optimized microfluidic components.

A computational "toolbox" for the a priori design of optimized microfluidic components is presented. These components consist of a microchannel under low-Reynolds number, pressure-driven flow, with an arrangement of grooves cut into the top and bottom to generate a tailored cross-channel flow. An advection map for each feature (i.

A microfluidic mixer with grooves placed on the top and bottom of the channel.

A new microfluidic mixer is presented consisting of a rectangular channel with grooves placed in the top and bottom. This not only increases the driving force behind the lateral flow, but allows for the formation of advection patterns that cannot be created with structures on the bottom alone. Chevrons, pointing in opposite directions on the top and bottom, are used to create a pair of vortices positioned side by side.

First successful case of in vitro fertilization-embryo transfer with venom immunotherapy for hymenoptera sting allergy.

BACKGROUND: To describe immune and endocrine responses in severe hymenoptera hypersensitivity requiring venom immunotherapy (VIT) during in vitro fertilization (IVF). CASE PRESENTATION: A 39-year old patient was referred for history of multiple miscarriage and a history of insect sting allergy. Four years earlier, she began subcutaneous injection of 100 mcg mixed vespid hymenoptera venom/venom protein every 5-6 weeks.

Laparoscopic approach to an uncommon adnexal neoplasm associated with infertility: serous cystadenofibroma of the fallopian tube.

A rare case of serous cystadenofibroma of the fallopian tube was discovered during evaluation for in vitro fertilization-embryo transfer. Bilateral tubal occlusion was noted on hysterosalpingogram, and a right adnexal cyst, initially thought to be of ovarian origin, was identified by office transvaginal sonography. Laparoscopy revealed a 5.

Bilateral orchiectomy for the surgical treatment of complete androgen insensitivity syndrome: patient outcome after 1 year of follow-up.

Objective: To describe an operative approach to bilateral orchiectomy for complete androgen insensitivity syndrome (AIS) and to report patient status 1 year after surgery.

Material And Method: A 19(1/2)-year-old woman with primary amenorrhea, cervical/uterine agenesis, elevated serum testosterone, and 46,XY karyotype underwent characterization of the androgen receptor mutation by polymorphism sequence analysis. Bilateral orchiectomy was performed via a triple-puncture 5-mm laparoscope, and postsurgical hormone replacement followed a daily oral contraceptive model.

Dizygotic twin delivery following in vitro fertilization and transfer of thawed blastocysts cryopreserved at day 6 and 7.

Objective: To report the first conception and delivery following transfer of thawed human blastocysts maintained in extended in vitro culture with cryopreservation at day 6 and 7.

Design: Case report.

Setting: Major urban infertility referral center.

Characterization of a novel receptor mutation A-->T at exon 4 in complete androgen insensitivity syndrome and a carrier sibling via bidirectional polymorphism sequence analysis.

The complete androgen insensitivity syndrome (AIS) is a sub-type of X-linked male pseudohermaphroditism resulting from total dysfunction of the androgen receptor. Affected patients are phenotypically female despite a 46,XY genotype; gonadal tissue displays a classic Sertoli cell-only pattern on microscopic examination. We describe the diagnosis and management of a 19(1/2)-year-old patient who presented for primary amenorrhea and absent cervix, identified incidentally during a routine Pap test.

Diagnostic and treatment characteristics of polycystic ovary syndrome: descriptive measurements of patient perception and awareness from 657 confidential self-reports.

BACKGROUND: This investigation was undertaken to describe patient perception and awareness of the polycystic ovary syndrome (PCOS), the most common cause of anovulation/oligoovulation among women of reproductive age. METHODS: Fifteen parameters were evaluated by a computer-based research instrument accessed by a large, unscreened population. Incomplete questionnaires were not entered, and responses were electronically tabulated to block duplicate submissions.
