We use a spatial light modulator (SLM) to diffract a single UV laser pulse to ablate multiple points on a Drosophila embryo. This system dynamically generates a phase hologram for ablating a user-defined pattern fast enough to be used with living, and thus moving, tissue. We demonstrate the ability of this single-pulse multi-point system to perform two experiments that are very difficult for co...

The use of a local excision to treat patients with early rectal cancer is increasing these days [1]. Local excisions have been commonly used because they have the benefits of decreased postoperative morbidity and mortality, good functional outcome, and avoidance of the need for a stoma [2]. However, the use of a local excision, when compared with a radical resection, such as a low anterior rese...

BACKGROUND Transanal endoscopic microsurgery (TEM) is a newly developed, minimally invasive technique for the local resection of rectal tumours. Its place needs to be defined. METHODS Literature review. RESULTS Local excision of rectal tumours is associated with low mortality and morbidity. It is indicated in adenomas for curation and in rectal cancer for palliation. Transanal resection is ...

INTRODUCTION The purpose of the present study was to evaluate the long-term clinical outcome of endodontic microsurgery when mineral trioxide aggregate (MTA) and super ethoxybenzoic acid (Super EBA; Harry J. Bosworth, Skokie, IL) were used as root-end filling materials. Additionally, this study aimed to compare the clinical outcome of endodontic microsurgery at the 1-year follow-up with that at...
