Depth profiles of absorbed hydrogen introduced by electrochemical charging and light elements were analyzed in Ni-Nb-Zr-H amorphous alloy ribbons using a glow discharge optical emission spectrometer. It was clarified that the absorbed hydrogen was comparatively well-distributed on the sample surface and that the content of the hydrogen decreased with increasing depth from the surface. That is, the amount of absorbed hydrogen on the surface was about 17 at %, while that inside the specimens decreased to several atomic percent. The depth profiles of the hydrogen which were close to the surface were slightly different between those on the roller side and those on the free side in the melt-spun ribbon. The difference is thought to originate from the existence of oxygen impurity on the surface and from the difference of the Zr content.

The electrical transport properties of (Ni0.8Nb0.2)100-xZrx (x = 30, 40 and 50) amorphous ribbons and hydrogen charged specimens were investigated. The amorphous ribbons indicated a negative coefficient in the temperature dependence of their electrical resistivity as well as the typical transport properties of the amorphous alloys with comparatively high values of electrical resistivity, ρ. The normalized temperature coefficient of the resistivity (TCR ≡ 1/ρ300K·dρ/dT) tended to increase with increasing x in the temperature range of 100-300 K. These behaviors would suggest that the transport properties of the present amorphous ribbons were governed by temperature variation of the Debye-Waller factor, not by electron-phonon scattering. The hydrogen charged ribbons obtained by an electrochemical method also showed similar electrical resistivity behaviors as a function of the temperature. However, TCR of x = 40 with hydrogen charged ribbon, in which the amount of absorbed hydrogen was about 14 at%, increased about three times more than that of the pre-charged amorphous ribbon.

In this paper, a wireless power transmission system using magnetic resonance coupling was proposed and demonstrated for supplying power at high efficiency to electrical devices in a space enclosed by metal walls. This is applicable to power supply to electrical sensors or devices working in the area surrounded by metal walls. Proposed magnetic resonance coupling system is driven at a resonance frequency of 50 Hz, which is selected to avoid eddy current loss on the surrounding metals. Firstly, resonator designs and its performance limitation were described. Secondly, the equivalent circuits and theoretical transmission efficiency were presented. Finally, power transmission was experimentally demonstrated and transmission efficiency was measured in some conceivable situations. As a result, electric power of 3 W was supplied to LEDs over a stainless steel wall. When the stainless steel wall thickness was 10 mm, transmission efficiency of approximately 40% was achieved over the transmission distance of 12 cm. Moreover, in the demonstration of transmission through a metal pipe, 1.2 W of power was transmitted to LEDs in a 10 mm thick metal pipe.

Background: Previous research has compared the efficacies of accelerated partial breast irradiation (APBI) and wholebreast irradiation (WBI). APBI immediately after surgery may provide more benefit after intraoperative insertion of catheters. Although balloon catheter-based APBI is available in the US, it is difficult in Japanese women, who have relatively small breasts. With the applicators being implanted during tumor removal, APBI can be started immediately after surgery. The aim of this study was to assess the safety and efficacy of APBI using the intraoperative open-cavity implant technique. Method: Patients (age≥40 years) with invasive breast cancer (diameter≤3 cm) were enrolled. Before lumpectomy, the insertion of applicators and delivery doses were simulated by computed tomography (CT). After confirmation of free margins and negative sentinel nodes (SNs) using frozen section analysis, applicators were inserted. Postoperative CT-based dose distribution analysis was performed using dose-volume histograms. APBI was started on the day of surgery, delivering 32 Gy in 8 fractions over the following 5-6 days, and it covered a distance of 2 cm from tumor margins. This observational study was approved by the institutional review board of our hospital. Results: From October 2008 to July 2012, 157 women (160 lesions) were enrolled (age 55.0 years, <40:9, SN+: 25, for patients’ request). The mean number of applicators used was 6.4 (2-15) and mean planning target volume was 35.8 cm3 (6.5-137.1 cm3). All radiotherapy-related toxicities were mild. However, 12 patients (7.5%) experienced wound breakdown because of surgical site infection. Two patients developed ipsilateral breast tumor recurrence (1 marginal, 1 at a distant site). Conclusions: Despite the small number of participants and a short follow-up period, our results suggest that this technique could be helpful in establishing clinical safety and efficacy.

Background: Breast-conserving surgery (BCS) followed by whole breast irradiation (WBI) has become the standard of care for treating patients with early-stage breast cancer. Recently, various radiation techniques followed by BCS have been reported. We have been investigating “personalized radiotherapy after BCS” ranging from accelerated partial breast irradiation (APBI) to WBI with regional nodal irradiation (RNI) based on the axillary node status. In this study, we compared different cohorts that received personalized radiotherapy. Method: Of 317 consecutive patients who underwent BCS followed by radiotherapy since November 2007, 187 who received APBI and 122 who received WBI were analyzed. Results: The local-only recurrence rate was 1.1% in the APBI group and 3.3% in the WBI group, and the regional-only recurrence rate was 1.1% for APBI and 0.8% for WBI. Conclusions: The clinical efficacy of APBI for local control after BCS was comparable to that of WBI ± RNI. Although this study was based on a small number of patients with a short follow-up period, the feasibility of breast-conserving therapy using multicatheter brachytherapy to achieve acceptable clinical outcomes was demonstrated.

目的:应用冠状动脉血管内视镜技术对ST段抬高和非ST段抬高的急性心肌梗死病人的罪犯血管进行观察,为研究急性心肌梗死的发生提供临床病理依据。方法:选择ST段抬高AMI(STMI)28例,非ST段抬高AMI(NSTMI)18例,在进行急诊冠状动脉介入性检查和治疗的同时,对罪犯血管进行血管镜检查。结果:STMI组和NSTMI组的罪犯血管内均可见到黄色斑块,其中NSTMI组中观察到斑块破裂者明显高于STMI组(88.89%vs57.14%,P=0.022)。STMI组中观察到红色或混合性血栓者明显高于NSTMI组(92.85%vs55.56%,P=0.003),并且前者以闭塞性血栓为主(78.57%vs11.11%,P<0.0001),后者以非闭塞性的壁在性血栓为主(44.44%vs14.29%,P=0.054)。结论:黄色不稳定性斑块破裂及其伴随的血栓形成,是引起AMI的病理基础;STMI以红色或混合性闭塞性血栓为主,而NSTMI则以非闭塞性的附壁血栓为主。因此,在黄色斑块破裂之前采取何种治疗措施使其稳定化,是预防AMI的关键。
