The biology of a koinobiont parasitoid of leaf-cutting ant larvae, Szelenyiopria talitae (Hymenoptera: Diapriidae), was studied from naturally infested Acromyrmex subterraneus (Hymenoptera: Formicidae) nests. Nests were collected in the field from the Atlantic rainforest biome in the state of Rio de Janeiro. A total of fifty-three nests were collected from 2015 to 2018. Parasitized nests were only found during the months of September and October. Approximately 22% of the nests collected over a four-year period were found to have been parasitized by S. talitae. The mean within-nest parasitism rate was 66.3%. This diapriid displayed both solitary (14%) and gregarious parasitism (86%), with up to a maximum of 12 parasitoids developing within a single host. Gregarious parasitism with two (29%) or three (21%) S. talitae per host was most frequently observed. There was a positive correlation between the number of parasitoids per host and host size (dry weight), indicating that S. talitae females oviposited a higher number of eggs in larger hosts. There was also a negative correlation between S. talitae<

世界核心医学期刊文摘（妇产科学分册） 2005年第6期1卷 42-43页

Paraaortic infrarenal lymphadenectomy is indicated in patients with gynecologic tumors of high metastasising potential and can be done successfully by laparoscopic approach. Vascular anomalies in this region are incidental findings during these approaches and may increase the surgical complication rate. In this study, we have documented the frequency and pattern of the vascular anomalies in paraaortic region intraoperatively and on cadavers in an attempt to increase surgical safety. A total of 86 consecutive patients underwent laparoscopic infrarenal paraaortic lymphadenectomy by a standardised technique between 1st of January 2002 and 1st of March 2004. Of the 86, 52 were primary cervical, 5 recurrent cervical, 14 endometrial, 14 early ovarian and 1 vulvar tumor with positive groin and pelvic lymph nodes. In the same time, anatomical dissections of the paraaortic region on 18 cadavers were performed at the Institute of Anatomy. Arterial or venous abnormalities were identified in 30.2% (26/86) of patients by laparoscopy. The most frequent anomalies were related to atypical renal arteries (pole arteries- 9 patients) and an abnormal course of lumbar veins directly draining in the left renal vein (15 patients). In one of the patients, the complete left renal vein went retroaortic to the inferior vena cava. In cadaveric dissections, vascular anomalies were noted in 44.4% (8/18) which included variations in renal and lumbar vessels and ovarian vessels. Duplicated inferior vena cava was the least common anomaly and was detected in only one case. During laparoscopic paraaortic inframesenteric and infrarenal lymphadenectomy, care must be taken because of possible abnormalities in arterially and venous system to avoid massive hemorrhage, transfusion and conversion to laparotomy.

一、雷击放电的形式 1.术语的定义通常在雷云的底层带负电荷,雷云的上层带正电荷。雷云中占优势的电荷决定了雷电流的极性。因此,正雷云对地放电称为正极性闪络,而负雷云对地放电称为负极性闪络。正极性闪络时雷云流向地中的是正电流,负极性闪络雷云流向地中的是负电流。由雷云对地发展的先导叫自上而下的先导。由地面对雷云发展的先导叫自下而上的先导。地面(或接地物)向上的先导与雷云向下的先导相遇而使雷云向地放电,这种形式的先导称为向上的连接先导。对雷云下电场极性的定义不完全一致。本书中把正雷云下的电场定为正极性。正电
