The investigation of electrical properties in alexandrite (BeAl2O4:Cr3+) in synthetic and natural forms is presented in this paper. Alexandrite is a rare and precious mineral that changes color according to the light incident on it. In the synthetic form, it is used technologically as an active laser medium. The electrical characterization was obtained using the Thermally Stimulated Depolarization Current (TSDC) technique, an interesting tool to study the behavior of impurities in insulators. Alexandrite presented the electric dipole relaxation phenomenon, both in natural and in synthetic samples. It was possible to observe TSDC bands for the synthetic sample at around 170 K, and at around 175 K for the natural sample. Besides, photo-induced TSDC measurements were performed through the excitement of the samples by using a continuous wave argon laser. In addition, photoluminescence measurements were performed to verify in advance whether the laser light would be absorbed by the sample, and in order to complement the photo-induced TSDC measurements analysis. The results of photo-induced TSDC experiments have contributed to the understanding of the TSDC bands behavior: the results obtained with the technique suggest that there is an effective participation of Cr3+ ions in the formation of TSDC bands because they were more intense when the sample was exposed to the argon laser beam.

本案位于日本东京涩谷的西武百货三楼，在这里汇集了众多现代时尚的奢侈品牌，因此每一个品牌在空间环境的构筑上都需要巧妙地与其他品牌区分开来。设计师OkiSato考虑到Compolux品牌女装在新品发布和产品更新上令人目眩的速度，因此将店面所需的陈列架设计成易挪动和变更的方式。陈列架的设计灵感源于公园、广场和其他欧洲城市绿色空间的铁艺围栏。这些围栏从天花上悬吊下来，用于悬挂衣物，并且内置了照明系统。悬吊架上的图案被设计出六种不同的样式，用于区分不同品牌的服装。

本文采用鹿角菜胶诱导的大鼠急性炎症模型观察橄榄叶提取物(OLE)的抗炎与镇痛作用及对致炎因子TNF-α和IL-1β的mRNA表达。用鹿角菜胶注射到大鼠右后足内,分别于鹿角菜胶注射前30 min和注射后120 min灌胃给予OLE 100、250和500 mg/kg体重。鹿角菜胶处理后测量足跖肿胀度及痛域。用RT-PCR检测足跖垫内组织TNF-α、IL-1β和IL-10的mRNA表达。结果显示,经灌胃给予OLE100、250和500 mg/kg体重,均能明显降低大鼠后足肿胀度,增加痛域,并明显降低致炎因子TNF-α和IL-1β的mRNA表达。本研究提示OLE具有抗炎和镇痛作用,其作用机制可能与抑制TNF-α和IL-1β的mRNA表达有关。

Laparoscopic cholecystectomy(LC) does not require advanced techniques, and its performance has therefore rapidly spread worldwide. However, the rate of biliary injuries has not decreased. The concept of the critical view of safety(CVS) was first documented two decades ago. Unexpected injuries are principally due to misidentification of human factors. The surgeon's assumption is a major cause of misidentification, and a high level of experience alone is not sufficient for successful LC. We herein describe tips and pitfalls of LC in detail and discuss various technical ***, based on a review of important papers and our own experience, we summarize the following mandatory protocol for safe LC:(1) consideration that a high level of experience alone is not enough;(2) recognition of the plateau involving the common hepatic duct and hepatic hilum;(3) blunt dissection until CVS exposure;(4) Calot's triangle clearance in the overhead view;(5) Calot's triangle clearance in the view from underneath;(6) dissection of the posterior right side of Calot's triangle;(7) removal of the gallbladder body; and(8) positive CVS exposure. We believe that adherence to this protocol will ensure successful and beneficial LC worldwide, even in patients with inflammatory changes and rare anatomies.

Purpose: Swallowing function was in a patient with tongue cancer that was evaluated with video fluorography before and after subtotal glossectomy and reconstruction with a rectus abdominis muscuocutaneous flap. Materials and Methods: A 41-year-old man underwent subtotal glossectomy and retained the unilateral posterior mylohyoid and unilateral stylohyoid muscles. The structure of the flap was evaluated postoperatively. To assess swallowing function, video fluorography was performed before surgery, 1 month after surgery and 1 year after surgery. Testing involved 1) ability to hold 10 mL of liquid in the oral cavity, 2) epiglottis turnover, 3) the presence of aspiration, 4) hyoid bone movement, and 5) maximum width of the esophageal entrance. Results: The flap was protuberant postoperatively. The patient was able to hold the test diet in the oral cavity before and after surgery. Epiglottis turnover was good before surgery but insufficient after surgery. Aspiration during swallowing was not observed before or after surgery. At rest, the hyoid bone sagged postoperatively, in comparison with preoperatively. Hyoid bone movement and width of the esophageal entrance decreased after surgery;however, they demonstrated gradual recovery. Conclusions: For good postoperative swallowing function after subtotal glossectomy, it is necessary to perform reconstruction with protuberant flap and to retain the suprahyoid muscles as much as possible.

We evaluated the prevalence of use of complementary and alternative medicine (CAM), as well as the transitional nature of its use, before and after radical prostatectomy in Japa-nese patients with localized prostate cancer. Methods: We enrolled 376 patients, who an-swered a self-administered questionnaire on CAM use, psychological health locus of control (HLC), and general-health-related quality of life (GHQL). Detailed information regarding CAM use according to the transtheoretical model, and the time at initiation and abandonment of CAM use were assessed. Medical information was also extracted from patient charts. Results: 45.7% of patients belonged to the “precontem-plation” stage, 29.8% to the “contemplation” stage, 1.9% to the “preparation” stage, 14.4% to the “action” stage, and 8.2% to the “relapse” stage. Although patient age and educational status had a significant impact on stage of CAM use, HLC and GHQL were not associated with them. The time-course of prevalence of CAM use during follow-up was divided into three phases: “initial,” “rapid-increase,” and “main-tenance”. Conclusions: Among patients under-going radical prostatectomy, non-users can be classified into several behavioral stages, while users do not use CAM constantly during fol-low-up.

Objective: The present study sought to determine changes in plasma levels of catecholamine metabolites and serum levels of brain-derived neurotorophic factor (BDNF) among smokers with schizophrenia who were treated with varenicline. Methods: We compared plasma homovanillic acid (HVA) and 3-methoxy-4-hydroxyphenylglycol (MHPG) levels and serum BDNF levels across 4 groups, divided as follows: smokers with schizophrenia (S-Sc), nonsmokers with schizophrenia (NS-Sc), smokers who were otherwise healthy (S-HC) and nonsmokers who were otherwise healthy (NS-HC). In addition, we also examined plasma HVA and MHPG levels and serum BDNF levels prior to study initiation (T0) and 8 weeks after varenicline treatment (T8) in the S-Sc and S-HC groups. Results: Plasma HVA levels in the S-Sc group at T0 were significantly higher than in the NS-Sc, S-HC and NS-HC groups at the same time point (S-Sc at T0;7.6 ± 1.6 ng/mL, NS-Sc;4.8 ± 1.0 ng/mL, S-HC;4.3 ± 0.9 ng/mL, NS-HC;3.4 ± 1.4 ng/mL, p < 0.0001). Plasma MHPG levels in the S-Sc group at T0 were significantly higher than in the NS-Sc and S-HC groups;in addition, plasma MHPG levels in the NS-HC group were significantly higher than in the S-HC group (S-Sc at T0;5.2 ± 0.7 ng/mL, NS-Sc;2.8 ± 1.2 ng/mL, S-HC;1.9 ± 0.8 ng/mL, NS-HC;3.6 ± 1.3 ng/mL, p < 0.0002). Serum BDNF levels did not differ between the S-Sc and NS-Sc groups. In contrast, no difference in plasma HVA levels, plasma MHPG levels or serum BDNF levels was observed between T0 and T8. Conclusions: In conclusion, plasma levels of HVA and MHPG in the S-Sc group were significantly higher than in the NS-Sc group. Serum BDNF levels did not differ between the S-Sc and NS-Sc groups. Plasma HVA and MHPG levels and serum BDNF levels did not change after treatment with varenicline.
