1Authigenic gypsum found in gas hydrate-associated sediments from Hydrate Ridge, the eastern North Pacific显示文摘Characteristic gypsum micro-sphere and granular mass were discovered by bin-ocular microscope in the gas hydrate-associated sediments at cores SO143-221 and SO143/TVG40-2A respectively on Hydrate Ridge of Cascadia margin, the eastern North Pacific. XRD patterns and EPA analyses show both micro-sphere and granular mass of the crystals have the typical peaks and the typical main chemical compositions of gypsum, although their weight percents are slightly less than the others in the non-gas hydrate-associated marine regions. SEM pictures show that the gypsum crystals have clear crystal boundaries, planes, edges and cleav-ages of gypsum in form either of single crystal or of twin crystals. In view of the fact that there are meanwhile gas hydrate-associated authigenic carbonates and SO42--rich pore water in the same sediment cores, it could be inferred reasonably that the gypsums formed also authigenically in the gas hydrate-associated environment too, most probably at the interface between the down-ward advecting sulfate-rich seawater and the below gas hydrate, which spilled calcium during its formation on Hydrate Ridge. The two distinct forms of crystal intergrowth, which are the granular mass of series single gypsum crystals at core SO143/TVG40-2A and the microsphere of gypsum crystals accompanied with detrital components at core SO143-221 respectively, indicate that they precipitated most likely in different interstitial water dynamic environments. So, the distinct authigenic gypsums found in gas hydrate-associated sediments on Hydrate Ridge could also be believed as one of the parameters which could be used to indicate the presence of gas hydrate in an unknown marine sediment cores.Erwin Suess Dirk Rickert 2004Science China Earth Sciences2004,47,3:10
2Laparoscopic surgery for rectal prolapse and pelvic floor disorders显示文摘Pelvic floor disorders are different dysfunctions of gynaecological, urinary or anorectal organs, which can present as incontinence, outlet-obstruction and organ prolapse or as a combination of these symptoms. Pelvic floor disorders affect a substantial amount of people,predominantly women. Transabdominal procedures play a major role in the treatment of these disorders. With the development of new techniques established open procedures are now increasingly performed lapa-roscopically. Operation techniques consist of various rectopexies with suture, staples or meshes eventually combined with sigmoid resection. The different approaches need to be measured by their operative and functional outcome and their recurrence rates. Although these operations are performed frequently a comparison and evaluation of the different methods is difficult, as most of the used outcome measures in the available studies have not been standardised and data from randomised studies comparing these outcome measures directly are lacking. Therefore evidence based guidelines do not exist. Currently the laparoscopic approach with ventral mesh rectopexy or resection rectopexy is the two most commonly used techniques. Observational and retrospective studies show good functional results, a low rate of complications and a low recurrence rate. As high quality evidence is missing, an individualized approach is recommend for every patient considering age, individual health status and the underlying morphological and functional disorders.Alexander Rickert Peter Kienle 2015World Journal of Gastrointestinal Endoscopy2015,7,12:6
