1聚酯和聚酰胺纤维最新进展显示文摘目前,所有类型的化学纤维(MMF)的需求量都在增长,相对于聚酰胺(PA)而言,对通用且成本低廉的聚酯(PES)的需求增长更快。迄今为止,使用量最大的聚酯是聚对苯二甲酸乙二酯(PET),其次是聚对苯二甲酸丁二醇酯(PBT)和聚对苯二甲酸丙二醇酯(PTT)。PA中主要使用的是PA6,其次是PA66。本文仅对上述化学纤维进行讨论。W.Chapman 王增效(译) 于俊荣(校) 2018国际纺织导报2018,46,8:2

3Male nutritional status does not impact the reproductive potential of female Cnaphalocrocis medinalis moths under conditions of nutrient shortage显示文摘In addition to sperm,some accessory substances transferred to females during copulation act as nuptial gifts by passing on valuable nutrients in many insect species.The nutritional status of the males can thus have a great effect on the mating behavior,fecundity and even the longevity of females.However,little is known about the effect of male nutritional status on the female reproductive traits in migratory insect species,particularly when females experience nutrient shortage and have to choose between reproduction and migration.Here,Cnaphalocrocis medinalis,a migratory rice pest in Asia,was studied to explore this issue.Our results showed that in male moths fed with honey solution,their gonads had higher energy content than gonads of starved males,resulting in increased energy content of the bursa copulatrix of females after mating with fed males.Such females showed increased mating frequency,fecundity and longevity compared to females mating with starved males,indicating that male moths deliver nuptial gifts to females and improve their reproductive performance.However,when females were starved,only about 45%mated,with just a single copulation,regardless of male nutritional status.Starved females showed lower fecundity,and a longer pre-oviposition period(indicating a greater propensity to migrate),compared to fed females.However,copulation still significantly extended their longevity.These results suggest that starved females invest in migration to escape deteriorating habitats,rather than investing the nuptial gift to increased fecundity.Our results further our understanding of the reproductive adaptability of migratory insects under conditions of food stress.Jia-Wen Guo Yu Cui Pei-Jiong Lin Bao-Ping Zhai Zhong-Xian Lu Jason W.Chapman Gao Hu 2022Insect Science2022,29,2:1
4Heminephrectomy for a large renal mass in a horseshoe kidney: A case report outlining a robotic assisted laparoscopic approach显示文摘With an incidence of 1/500,a horseshoe kidney is not uncommon.Tumours discovered in horseshoe kidney however are quite rare,and prove difficult to surgically manage due to complex vascular anatomy.With variable surgical approaches previously described,only a select few robot-assisted cases have been reported.This case describes one such robot-assisted laparoscopic heminephrectomy,with the use of indocyanine green and an endovascular stapler to successfully demarcate ischemia and achieve hemostasis intraoperatively.No complications were encountered,and pathology revealed a pT1bN0 clear cell renal cell carcinoma with negative surgical margins,demonstrating the feasibility of our approach.Matthew Mancuso Benjamin B.Beech David W.Chapman Blair St Martin 2022Laparoscopic, Endoscopic and Robotic Surgery2022,5,2:0
