Total laryngectomy has a history of over 100 years, hence many surgeons are accustomed to the en bloc organ resection and the loss of ability for communication after surgery. The recent advance of surgery introduces the concept and technique of radical cure and functional preservation of the cancer-afflicted-organ at same setting. For lesions of late T categories (T3, T4), the maintenance of normal function after wide resection to ensure radicality demands a special technique to repair the crippled larynx. For this purpose a local osteomuscular flap was designed to reconstruct a functioning larynx. The surgical manoeuvre was described and the result proved to be successful. The outcome of 138 patients with T3 and T4 laryngeal carcinomas following conservation laryngectomy was analyzed. The five-year survival rate was 69% for supraglottic type and 75% for glottic type. The quality of life was much improved.展开更多

Here, we explore the degree to which individual differences in anti-predator response （or boldness） influence survival rates in groups of snails Chlorostoma funebralis when they encounter a predatory sea star Pisaster giganteus. The snail C. funebralis shows consistent individual variation in predator response where some fearful snails actively flee bodies of water occupied by predators whereas bolder snails consistently do not. We show here that bold snails are significantly more likely to survive encounters with a predatory sea star and, somewhat counterintuitively, fearful snails actually suffer higher mortality rates. We also found that smaller snails and those occurring at higher experimental densities experienced higher per capita survival rates. Positive effects of prey boldness on survival are not uncommonly reported in the animal personality literature; however, such results are inconsistent with classic animal personality theory borrowed from the optimal foraging literature. The findings herein add to the growing body of evidence that consistent individual differences in behavior can impact predator-prey interactions and that boldness is potentially under positive predator-driven selection in some systems.展开更多
