[Assisted reproductive technologies with sperm donation].

Introduction: The purpose of this review is to relate to the operating rules of CECOS in France and the legal, medical and ethical issues raised by sperm donation.

Material And Methods: Review of articles and consensus conferences on this subject published in Medline (PubMed) selected from 1973 and 2011 according to their relevance and Acts recorded on official legislative French websites.

Results: The operating rules of CECOS were established by the Act of July 29, 2004, revised 6 August 2004 and July 7, 2011.

[1998 french results on medically assisted reproduction with gamete cryopreservation and donation. French Federation of CECOS].

During the year 1998, the French Federation of CECOS recorded the results of the 23 CECOS centers and IFRAERES in Toulouse. 1,573 first demands of procreation with sperm donors were registed (versus 1,620 in 1997). From 9,339 cycles (AID or IVFD), 1351 pregnancies were obtained, scoring the identical amount in terms of pregnancies as in 1997 but with less 9% in terms of cycles.

Identification of hydroxypyruvate reductase from parsley by peptide sequence comparison after a two-step purification.

Hydroxypyruvate reductase (HPR), a plant leaf peroxisomal enzyme involved in the glycolate pathway, has been purified in two steps from a crude extract of parsley leaves during the purification of an unrelated ATP-dependent enzyme. HPR, a homogenous side-fraction arising from this purification procedure, was identified after sequencing of three internal peptides which showed near 100% homology with the amino acid sequence deduced from the cDNA encoding the NADH-dependent HPR from cucumber. This is an example of the identification of the activity of an unknown protein through direct sequence work.

Iliac artery patency before and immediately after percutaneous transluminal angioplasty: assessment with time-of-flight MR angiography.

Purpose: To assess the efficacy of magnetic resonance (MR) angiography of iliac arteries before and immediately after percutaneous transluminal angioplasty (PTA).

Materials And Methods: In 14 patients with 22 diseased iliac artery segments (external or common), axial two-dimensional time-of-flight MR angiography was performed. Images were reconstructed with a maximum-intensity-projection (MIP) algorithm.
