A traditional fox cage was furnished with both activating environmental enrichments (EE) (a bone, a scratching plate, a hockey buck, a ceiling rope and a wall rope and straw) and EEs enabling resting or observation (a wire-mesh platform and a top nest box). The aim was to find out to which extent blue foxes (Vulpes lagopus) utilized these EEs, and to collect practical experiences of the EEs. The experimental animals were 12 adult blue fox vixens that had been housed in cages furnished with a platform and a bone for about 1.5 years before they were transferred to the multi-enriched cages. The frequency and duration of the active contacts with the EEs were measured with continuous recording on Days 1, 2, 7 and 16 after the transfer, with three hours (13:30 - 14:30, 18:00 - 19:00 and 2:00 - 3:00) on each day. The total use of the EEs was 15 times per hour and more than 20% of the time. For most EEs both the time spent in contact and the frequency of contacts with the EEs declined steeply after Day 1, reflecting a novelty effect of the EEs. This decline was not so evident for the platform, top nest box and wall rope. These three EEs were also the ones used the most by the foxes. The ropes were badly damaged during the experiments, whereas other EEs remained in good condition. Explorativity markedly increased when animals were transferred from home cage to enriched cages. Explorativity remained high during entire study period when foxes were kept in enriched enrichment. Furthermore, it remained high also after transferring of animals back to home cages. Capture reaction was quite similar in home and enriched cages. The amount of stereotypy varied among recording days (P < 0.05). When foxes were transferred from home cages to multi-enriched cages, no change was found in the amount stereotypy during Days 1 and 2. Thereafter, the amount of stereotypy showed a declined trend. Stereotypy tended to increase when foxes were transferred back to home cages. Our results indicated

Objective: To determine whether the CAG repeat length of the androgen receptor (AR) gene contributes to individual differences in the susceptibility to the development of polycystic ovary syndrome (PCOS). Design: Retrospective case- control study. Setting: University- based clinic. Patient(s): One hundred six nondiabetic women with PCOS and 112 nonhirsute fertile controls. Intervention(s): Androgen receptor gene CAG repeat length was analyzed in women with PCOS and their controls. Main Outcome Measure(s): Androgen receptor gene CAG repeat length in both groups. Result(s): The mean CAGn was 21.5 repeats in both groups (NS; t- test). Furthermore, when the CAGn lengths were divided into three categories (CAGn ≤ 18, 19- 24, ≥ 25), the distribution was similar in both groups (NS; χ 2 test). However, all five women carrying ≤ 15 CAG repeats belonged to the PCOS group. In the PCOS group, CAGn did not correlate with body mass index or serum testosterone concentration. Conclusion(s): Androgen receptor CAGn is not a major determinant of PCOS. However, it may be a significant modulator of androgen- related diseases in some individuals.

在过去十年中,用于加热和表面处理的辉光放电工艺在许多工业领域取得了愈来愈有价值的应用,其应用范围从微电子元件的处理和光学应用到表面硬化和沉积耐磨的薄膜与涂层。虽然通常,辉光放电过程的物理细节及其所形成的涂层或表面层的微观结构不完全清楚,然而只要适当调整工艺条件就能产生用一般常规方法难于得到的各种有用组织。新近的例子有沉积高耐磨的氮化钛涂层和钛制零件的等离子氮化。本文将评述这些工艺的基本区别和应用,并指出一些进一步发展的倾向。

子女患癌症1年后父母的生活状况

Aim: To evaluate the impact of childhood cancer on the life of the parents. Me thod: A 1-y follow-up study, with two time points for questionnaires, was comp leted in 21 out of 26 eligible families, and there were 46 control families matc hed by mothers’educational status. Results: Half of the mothers worked outside home during the first year of their child’s illness. The perceived amount of lo st family income was high during the first few months. The attitudes of the pare nts were fairly positive as their family life and spouse relations were concerne d. Feelings of being under strain or stressed were, by the mothers, described as intolerable in the beginning. However, standardized anxiety assessment failed t o show an increase in feelings of anxiety. Own health was rated significantly ne gative by cancer parents. Conclusions: Despite good family relationships, a need for supportive measures exists, especially during the first few months, and in -depth interviews by psychologists or special nurses might be a way of finding out possible anxiety. The perceived feelings of own health may also be an indica tor of the level of distress. Parent support groups could also do more to offer opportunities of physical activities for the parents, not merely disease-relate d information and group discussions.
