Nonhydrogenated cottonseed oil can be used as a deep fat frying medium to reduce trans-fatty acid content in french fries.

Objective: The purpose of this research study was to evaluate the fatty acid profile, in particular trans-fatty acids, of french fries fried in nonhydrogenated cottonseed oil as compared with french fries fried in partially hydrogenated canola oil and french fries fried in partially hydrogenated soybean oil.

Design: Cottonseed oil, partially hydrogenated canola oil, and partially hydrogenated soybean oil were subjected to a temperature of 177 degrees C for 8 hours per day, and six batches of french fries were fried per day for 5 consecutive days. French fries were weighed before frying, cooked for 5 minutes, allowed to drain, and reweighed.

Comparison of pregnancy, implantation, and multiple gestation rates for day 3 versus day 5 embryo transfers.

Purpose: To compare pregnancy, implantation, and multiple gestation rates resulting from day 3 and day 5 embryo transfers after in vitro fertilization emphasizing a subset of patients who met criteria for day 5 transfer but elected to undergo day 3 transfer.

Method: A retrospective analysis of day 3 and day 5 embryo transfers from January 2001 to June 2002 were evaluated in a community teaching hospital setting. A total of 331 patients < or = 40 years old were included.

Successful pregnancy resulting from cryopreserved pronuclear and cleaved embryos thawed and cultured to blastocysts, refrozen and transferred. A case report.

Background: Twice-frozen, thawed embryos may have utilization in vitro fertilization (IVF) cycles.

Case: A 37-year-old woman with endometriosis and infertility returned five years after a fresh IVF cycle. Seven cryopreserved embryos (2 pronuclear [pn] and cleaved) were thawed, and five developed to the blastocyst stage.
