Sensitization of escape in female Betta splendens

Following 1 day of cohabitation with a male, female Siamese fighting fish showed heightened escape from male conspecifics (enclosed behind glass). Escape from males was general in that no particular male stimulus was required to provoke female escape. However, female conspecifics remained relatively attractive following exposure to a male. Tactile stimulation of females by males (biting, perhaps) plays some role and may be required in sensitizing females' escape from males. © 1996 Wiley-Liss, Inc.     

What is the function of nail biting: an analog assessment study

OBJECTIVE: To compare the frequency of nail biting in 4 settings (interventions) designed to elicit the functions of nail biting and to compare the results with a self-report questionnaire about the functions of nail biting. DESIGN: Randomised allocation of participants to order of conditions. SETTING: University Psychology Department. SUBJECTS: Forty undergraduates who reported biting their nails. INTERVENTIONS: Left alone (boredom), solving maths problems (frustration), reprimanded for nail biting (contingent attention), continuous conversation (noncontingent attention). MAIN OUTCOME MEASURES: Number of times the undergraduates bit their nails. RESULTS: Nail biting occurred most often in two conditions, boredom and frustration. CONCLUSION: Nail biting in young adults occurs as a result of boredom or working on difficult problems, which may reflect a particular emotional state. It occurs least often when people are engaged in social interaction or when they are reprimanded for the behavior.     

宫颈癌根治术前预处理减少输尿管损伤及下肢静脉血栓临床观察

通过对术前考虑盆腔粘连可能比较严重的宫颈癌根治术（RH）术中穿着医用弹力袜行双下肢弹力加压,并经膀胱镜放置输尿管导管作预处理,减少下肢静脉血栓及输尿管损伤的临床效果。回顾性研究在我院行手术治疗的术前考虑盆腔粘连可能比较严重的宫颈癌患者364例,其中182例接受广泛子宫切除及盆腔淋巴结清扫术,术中穿着医用弹力袜行双下肢弹力加压,作为研究组,另182例单纯接受广泛子宫切除及盆腔淋巴结清扫术,未作预处理,作为对照组。结果研究组无一例损伤输尿管,对照组2例发生输尿管损伤（P ＜0．05）。因此,术前考虑盆腔粘连可能比较严重的 RH 术中穿着医用弹力袜行双下肢弹力加压,并经膀胱镜放置输尿管导管常规作预处理,可明显减少下肢静脉血栓、尿潴留及输尿管损伤,值得临床推广应用。
