Some gene therapy research trials have been performed in humans with mixed results. The future for gene therapy in hemophilia is continuing albeit at a moderate pace. There are many projects continuing in animal models.Improved long-term expression of the new genes will require the development of better vectors (the means of delivering the new genes into the cells).Call NHF's toll free number (1-800-42-HANDI) for more information about gene therapy for hemophilia.here are many projects continuing in animal models.

An ultrasound exam is a procedure that uses high-frequency sound waves to scan a womanâs abdomen and pelvic cavity, creating a picture (sonogram) of the baby and placenta.Although the terms ultrasound and sonogram are technically different, they are used interchangeably and reference the same exam.ltrasound dating of conception is not reliable for determining paternity because the ultrasound can be off by at least 5-7 days in early pregnancy. You may have an ultrasound between 18 to 20 weeks to evaluate dates, a multiples pregnancy, placenta location or complications.
