Dorsal closure during Drosophila embryogenesis is an important model system for investigating the biomechanics of morphogenesis. During closure, two flanks of lateral epidermis (with actomyosin-rich purse strings near each leading edge) close an eye-shaped opening that is filled with amnioserosa. At each canthus (corner of the eye) a zipping process remodels the tissue interfaces between the le...

There is a strong trend at hand toward less dramatic facial rejuvenation surgery. Most of the authors' patients want a cosmetic improvement but not at the cost of prolonged disfigurement or a high risk of complications. In 1999, a very simple but effective rhytidectomy technique, termed an S-lift, was described in the literature and was adopted by the authors. Its basic principle is the suspens...

The paper describes the status of a joint project between Gemplus and ONERA. Gemplus developed an electronic purse running on Java enabled smart cards. The project goal is to verify security properties that should be enforced by the applets involved in this application. A security policy has been defined that associates levels to applet attributes and methods and defines authorized flows betwee...

Despite the variety of novel facial rejuvenation technologies available today, the reference standard for correction of the senescent jaw line and neck remains rhytidectomy. This article describes the purse-string facelift, a vertical facelift that moves away from traditional techniques that use a horizontal vector of subcutaneous muscle-aponeurotic system repositioning. The vertical facelift c...

background: appendectomy is the most common emergency operation performed in the world. this study aimed to compare complication of simple legation of the appendix with purse string diving appendectomy. methods: randomized clinical trial designed 361 patients who had underwent appendectomy during 2008 and 2009 in imam reza and taleghani hospitals, kermanshah, iran, were included. those patients...

The standard way of visualising protocols using pictures with boxes and arrows is insufficient to study the protocols in detail. The problem is that the structuring of the protocols relies on elements not explicit in the standard visual rendering. To solve the problem one should visualise not only the operations and the messages but also the state and the security. Using an object oriented data...

A highly effective surgical technique is required for laparoscopic low rectal transection without sufficient distal margins when ultralow anterior resection (ULAR) with a stapler is a technical challenge for laparoscopic surgery. We report a retrograde single stapling technique (RSST) for laparoscopic ULAR. Total mesorectal excision is performed laparoscopically. After the anal side of the tumo...

PURPOSE To introduce a novel approach to analyze and model facial movements; and to quantify variations in facial movement caused by the extent of skeletal differences between the maxilla and mandible and the middle to lower facial heights. The hypothesis was that there are differences in facial movement related to the underlying facial skeleton which may be explained by the shape of the face r...

Failure of arthroscopic techniques in cases of recurrent anterior glenohumeral instability may result from inadequate treatment of capsular injury. The use of few anchors has been cited as a cause of failure in arthroscopic stabilization techniques. This applies to the use of the suture anchors as spot-welding points in conventional techniques. It has been shown that horizontal mattress suture ...
