From the laboratory to the field: efficacy of entomopathogenic nematodes to control the cattle tick.

Background: The control of ticks is challenged by the resistance of tick populations to chemical acaricides. In this study, we evaluated, under laboratory conditions, the efficacy of Heterorhabditis bacteriophora against Rhipicephalus (Boophilus) microplus engorged females with varying body weights (150, 200, 250, 300 or 350 mg per female) or from eight different geographical populations. We also determined the efficacy of H.

Activity Against Musca domestica of Hypocrealean Fungi Isolated from Culicids in Central Brazil and Formulated in Vermiculite.

Musca domestica L. is a cosmopolitan nuisance of high sanitary importance. Entomopathogenic fungi are innovative and attractive tools for integrated control of the housefly to overcome insufficient levels of control caused by increasing resistance of this pest against chemical insecticides.

International multicenter trial on clinical natural orifice surgery--NOTES IMTN study: preliminary results of 362 patients.

Objectives: Natural orifice translumenal endoscopic surgery (NOTES) is evolving as a promising alternative for abdominal surgery. IMTN Registry was designed to prospectively document early results of natural orifice surgery among a large group of clinical cases.

Methods: Sixteen centers from 9 countries were approved to participate in the study, based on study protocol requirements and local institutional review board approval.

NOTES: transvaginal for cancer diagnostic staging: preliminary clinical application.

Laparoscopy is now a reliable method for staging gastrointestinal cancer, orienting the therapy, and avoiding unnecessary laparotomy. Natural orifice transluminal endoscopic surgery (NOTES) is an emerging concept with potential advantages for patient recovery. The first case of clinical diagnostic application of transvaginal NOTES for diagnostic cancer staging is presented.

NOTES. Transvaginal cholecystectomy: report of the first case.

Natural Orifice Translumenal Endoscopic Surgery is a new development area with potential advantages for patients. However, technical and ethical challenges involved in perforation and closure of a healthy organ, as seen in transgastric access, and lack of comprehension of physiopathology of these approaches haven't allowed clinical application. The present study, based on previous animal experiments, describes the first clinical application of transvaginal Natural Orifice Translumenal Endoscopic Surgery.
