Tubal anastomosis after tubal sterilization: a review.

Purpose: To evaluate various techniques for restoring tubal patency after sterilisation.

Methods: A search strategy was designed, and for each subject either thesaurus terms (MeSH descriptors) or terms from the title or summary were used.

Results: Mean length of hospital stay following laparoscopy seems to be shorter in comparison with laparotomy (3.

Vaginal myomectomy: literature review.

The objective of this literature review was to evaluate the results obtained at vaginal myomectomy. The databases consulted were Medline, Cochrane Library, National Guideline Clearinghouse, and Health Technology Assessment Database. Keywords used for research were colpotomy, myomectomy, and vaginal myomectomy, and then abdominal myomectomy, laparoscopic-assisted vaginal myomectomy, and laparoscopic myomectomy.

Gating of heteromeric retinal rod channels by cyclic AMP: role of the C-terminal and pore domains.

Cyclic nucleotide-gated channels are tetramers composed of homologous alpha and beta subunits. C-terminal truncation mutants of the alpha and beta subunits of the retinal rod channel were expressed in Xenopus oocytes, and analyzed for cGMP- and cAMP-induced currents (single-channel records and macroscopic currents). When the alpha subunit truncated downstream of the cGMP-binding site (alpha D608stop) is co-injected with truncated beta subunits, the heteromeric channels present a drastic increase of cAMP sensitivity.
