摘要目的评估使用64层螺旋CT以及低剂量对比剂(25mL)在诊断和处理成人非创伤性蛛网膜下腔出血(SAH)的技术性能和诊断价值。方法本研究未在美国本土施行,获得伦理委员会批准。对73例经CT平扫诊断为非创伤性SAH的病人进行颅脑CTA检查。2名放射科医师采用2条标准对影像进行评估:动脉强化程度和静脉干扰。各自以血管成像为参考标准来评估其诊断价值(病变检出及治疗决策)。

Invasive rats （Rattus spp.） are known to have pervasive impacts on island birds, particularly on their nesting success. To conserve or restore bird populations, numerous invasive rat control or eradication projects are undertaken on islands worldwide. However, such projects represent a huge investment and the decision-making process requires proper assessment of rat impacts. Here, we assessed the influence of two sympatric invasive rats （Rattus rattus and R. exulans） on native bird eggs in a New Caledonian rainforest, using artificial bird-nest monitoring. A total of 178 artificial nests containing two eggs of three different sizes were placed either on the ground or 1.5 m high and monitored at the start of the birds＇ breeding season. Overall, 12.4% of the nests were depredated during the first 7 days. At site 1, where nests were monitored during 16 days, 41.8% of the nests were depredated. The main predator was the native crow Corvus moneduloides, responsible for 62.9% of the overall predation events. Rats were responsible for only 22.9% of the events, and ate only small and medium eggs at both heights. Our experiment suggests that in New Caledonia, predation pressure by rats strengthens overall bird-nest predation, adding to that by native predators, Experimental rat control operations may allow reduced predation pressure on nests as well as the recording of biodiversity responses after rat population reduction.

Stress of the Off-Season May Be Greater for the Student-Athlete than during Competition: A Pilot Study

引用

Journal of Behavioral and Brain Science 2017年第7期7卷 304-310页

作者： Jeannie d. diClementi Anna Reese Tyler Borsa department of Psychology Indiana University-Purdue University Fort Wayne Fort Wayne IN USA

We assessed 16 student-athletes in their first year of college on several dimensions, including severity of psychological and physical symptoms, mental health upset, academic concerns, suicidal tendencies, depressive outlook, anxiety and tension, attention difficulties, and alcohol abuse. We assessed half during their sports’ competition season and half during their off-season. Results pointed to increased perceived stress during the down time of off season. It may be that for student-athletes, the structure of competition season offsets the stress of competition, such that when the structure is removed or lessened, perceived stress increases. Implications of these data are discussed as well as plans for developing follow-up studies.
