PURPOSE: Nowadays laparoscopic colorectal surgery has demonstrated its advantages, including reduced postoperative pain, decreased duration of ileus, and shorter hospital stay. Few studies report results of laparoscopic surgery in complicated diverticulitis. This study was designed to analyze the results of laparoscopic sigmoidectomy in patients with fistulized sigmoiditis. METHODS: The authors retrospectively reviewed 16 patients who had laparoscopic sigmoidectomy for fistulized diverticulitis between 1992 and 2003 in a series of 247 laparoscopic colectomies. Eleven patients presented with colovesical, four with colovaginal, and one with colocutaneous fistulas; all were caused by sigmoiditis. The procedure always consisted of celioscopic sigmoidectomy with stapled transanal suture and, when indicated, closure of the cystic or vaginal fistula orifice. RESULTS: Mean age was 60 (range, 39-78) years. Mean number of episodes of diverticulitis before operation was three (range, 1-5). Mean time between the last episode and operation was 46 (range, 2-250) weeks. In our first three years of experience, three cases (18.7 percent) were converted to laparotomy. Reasons for conversion were the necessity for intestinal resection, splenectomy, and a wound of the anterior rectum. The mean operative time was 172 (range, 100-280) minutes. Mean hospital stay was 5.7 (range, 3-12) days. There was no mortality. Postoperative morbidity (2 patients, 12.5 percent) consisted of one pulmonary infection and one splenectomy. Long-term follow-up revealed no recurrence of diverticulitis and one incisional hernia. CONCLUSIONS: In experienced hands, laparoscopic sigmoidectomy may be a safe and effective procedure for fistulized sigmoiditis. [less ▲]

The use of laparoscopically assisted vaginal hysterectomy with or without annexectomy has been widely discussed. We report the technique of laparoscopic supracervical (subtotal) hysterectomy (LASH), which was first performed in 1990. Laparoscopic supracervical hysterectomy was carried out in a series of 36 women. The duration time was 60 min in experienced hands. There were no major complications. The feasibility and low morbidity rate of this laparoscopic approach led us to propose LASH in certain indications, particularly in cases of a uterus with multiple submucosal myomas where hysteroscopic therapy is less successful.

Reports of laparoscopy in heart graft recipients are scarce and, to our knowledge, laparoscopic colectomy has not yet been reported in heart transplant patients. The magnitude and the tolerance of the hemodynamic changes induced by pneumoperitoneum are unknown in heart graft recipients, who have a denervated heart and are "preload-dependent". The authors report the clinical courses of 2 heart graft recipients who developed acute diverticulitis without perforation or peritonitis and who underwent laparoscopic-assisted colectomy without complications.

La séduisante archéologue Lara Croft, protagoniste de la série de jeux Tomb Raider, est aujourd'hui l'une des icônes les plus célèbres du jeu vidéo, si bien qu'elle a même dépassé les limites de ce médium pour se faire connaître à un public élargi (à travers des adaptations au cinéma, en comics ou encore à travers des publicités). Toutefois, ce personnage est aussi une figure complexe qui a été reçue de manières très diverses : tantôt envisagée comme un symbole féministe (Lara Croft est une héroïne forte et indépendante, loin de la demoiselle en détresse à laquelle se cantonnaient généralement les premiers jeux vidéo), elle a aussi pu être interprétée comme une représentation caricaturale et réifiante de la femme. C'est donc d'un personnage chargé de contradictions que cette conférence propose de faire le portrait. [less ▲]

Earlier systematic nonlinear treatments of parallel propagating electromagnetic waves have been given within a fluid dynamic approach, in a frame where the nonlinear structures are stationary and various constraining first integrals can be obtained. This has lead to the concept of oscillitons that has found application in various space plasmas. The present paper differs in three main aspects from the previous studies: first, the invariants are derived in the plasma frame, as customary in the Sagdeev method, thus retaining in Maxwell's equations all possible effects. Second, a single differential equation is obtained for the parallel fluid velocity, in a form reminiscent of the Sagdeev integrals, hence allowing a fully nonlinear discussion of the oscilliton properties, at such amplitudes as the underlying Mach number restrictions allow. Third, the transition to weakly nonlinear whistler oscillitons is done in an analytical rather than a numerical fashion. (C) 2005 American Institute of Physics. [less ▲]

Waves in electron-positron plasmas have fundamentally different dispersion characteristics due to the equal charge-to-mass ratios between negative and positive charges, which mix different timescales, and are of interest in understanding aspects of pulsars and active galactic nuclei, where astrophysical electron-positron plasmas occur. Earlier systematic nonlinear treatments of parallel propagating electromagnetic waves via a reductive perturbation analysis had indicated unusual results, namely a vector equivalent of the modified Korteweg-de Vries equation. The latter is nonintegrable except in the case of linear polarization when it becomes equivalent to the scalar (integrable) modified Korteweg-de Vries equation. Here large amplitude purely stationary nonlinear solitary waves are studied in their own reference frame via the McKenzie approach. The behavior of the wave magnetic field can be expressed through an energy integral that involves the Mach number of the structure. Possible solitons are super-Alfvenic and occur symmetrically for positive or negative fields, owing to the obvious symmetry between positive and negative charges with the same mass. The limits on the allowable Mach numbers and soliton amplitudes have also been computed. (C) 2004 American Institute of Physics. [less ▲]

This review focuses on carrion beetles (Coleoptera, Silphidae) of the Western Palearctic and their potential use in forensic entomology as bioindicators. Few studies have looked at Silphidae in forensic context and investigations. However, some Silphidae present the desirable characteristics of some Diptera used in postmortem estimates and thus may extend the minimum postmortem interval (PMImin). We review here the taxonomy and distribution of Western Palearctic Silphidae. The anatomical and morphological characteristics of both subfamilies are described for adults and larvae. The biology and ecology of silphids are also summarized for Silphinae and Nicrophorinae. A specific chapter gives an overview of the current uses of Silphidae in forensic entomology as postmortem indicator. [less ▲]

The membrane-proximal external region (MPER) of the gp41 fusion protein of HIV is highly conserved among isolates of this virus and is considered a target for vaccine development. This region also appears to play a role in membrane fusion as well as localization of the virus to cholesterol-rich domains in membranes. The carboxyl terminus of MPER has the sequence LWYIK and appears to have an important role in cholesterol interactions. We have tested how amino acid substitutions that would affect the conformational flexibility of this segment could alter its interaction with cholesterol. We studied a family of peptides (all peptides as N-acetyl-peptide amides) with P, G, or A substituting for W and I of the LWYIK sequence. The peptide having the greatest effect on cholesterol distribution in membranes was the most flexible one, LGYGK. The corresponding mutation in gp41 resulted in a protein retaining 72% of the fusion activity of the wild-type protein. Two other peptides were synthesized, also containing two Gly residues, GWGIK and LWGIG, and did not have the ability to sequester cholesterol as efficiently as LGYGK did. Making the corresponding mutants of gp41 showed that these other two double Gly substitutions resulted in proteins that were much less fusogenic, although they were equally well expressed at the cell surface. The study demonstrates that drastic changes can be made in the LWYIK segment with the retention of a significant fraction of the fusogenic activity, as long as the mutant proteins interact with cholesterol.

As scaling of the critical transistor dimensions below 65 nm has been slowed down, the implementation of novel materials, especially high mobility channel materials is most attractive to boost the transistor performance. Applying strain to silicon has become a successful route. The electron mobility can be enhanced by biaxial strain introduced into Si by epitaxial growth of Si on a strain relaxed SiGe layer or by so called process induced methods applied directly on transistor level. The combination of strained Si and SOI is particularly promising due to the combination of the enhanced mobilities and the inherent advantages of SOI. First long channel n-MOSFETs with gate lengths of 5 to 50 mum and a 6.6 nm thick SiO2 gate dielectric were fabricated. For comparison, devices on unstrained SOI were made. The transfer characteristics of a fully depleted sSOI-MOSFET with a gate length of 5 mum and a gate width of 20 mum indicating an inverse sub-threshold slope of 75mV/dec. [less ▲]

New demands for space and earth observations drive the need for large apertures of 10 m and higher in telescopes. This requires new types of alternative lightweight and deployable primary reflector or lens concepts with aerial densities of\3 kg/m2. Some syntheses between optical and especially mechanical and material aspects for large planar photon sieves and non-imaging telescopes are discussed. Focus is put on large planar and highly perforated membranes for photon sieves and shell-membrane type deployable (parabolic) reflectors, respectively. The reflecting surface of the latter is composed of specific C-fiber reinforces silicone (CFRS) material. In addition to possible shape control, emphasis is also given to reflective coating of CFRS. Engineering challenges requiring future activities are identified. [less ▲]
