Protein profiles of bovine placenta derived from somatic cell nuclear transfer.

Practical application of animal cloning by somatic cell nuclear transfer (SCNT) has been hampered by an extremely low success rate. To address whether placental dysfunction in SCNT causes fetal loss during pregnancy, we have used a global proteomics approach using 2-DE and MS to analyze the differential protein patterns of three placentae from the afterbirth of cases of postnatal death, derived from SCNT of Korean Native cattle, and three normal placentae obtained from the afterbirth of fetuses derived from artificial insemination. Proteins within a pI range of 4.

Surgical management of vaginal wound healing defects after tension-free vaginal tape placement.

The use of tension-free vaginal tape (TVT) made of polypropylene mesh carries the risk of causing vaginal wound healing defects, which are usually detected within 4 weeks of operation. We present three cases of vaginal wound healing defects after TVT procedures. These defects were managed using surgical techniques aimed at preserving the mesh, but all failed.
