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.

Results. If you have the test as an emergency you may get the results the same day. If the test is a routine one and you havenât heard from the hospital after a couple of weeks, contact your doctor's secretary or GP. You can view and print the quick guide for this page about ultrasound scans.
If a vaginal ultrasound is done and no fetal pole or cardiac activity is seen, another ultrasound scan should be done in 3-7 days. Due to the fact that pregnancy dating can be wrong, it would be much too early at this point to make a clear diagnosis on the outcome of the pregnancy. Gestational Age Week 7 (Fetal Age: 5 weeks) Generally, from 6 Â½ -7 weeks is the time when a heartbeat can be detected and viability can be assessed. A normal heartbeat at 6-7 weeks would be 90-110 beats per minute. The presence of an embryonic heartbeat is an assuring sign of the health of the pregnancy.
