Flexible and easily reconfigurable supercapacitors show great promise for application in wearable electronics. In this study, multiwall C nanotubes （CNTs） decorated with hierarchical ultrathin zinc sulfide （ZnS） nanosheets （ZnS@CNT） are synthesized via a facile method. The resulting ZnS@CNT electrode, which delivers a high specific capacitance of 347.3 F·g^-1 and an excellent cycling stability, can function as a high-performance electrode for a flexible all-solid-state supercapacitor using a polymer gel electrolyte. Our device exhibits a remarkable specific capacitance of 159.6 F·g^-1, a high energy density of 22.3 W·h·kg^-1, and a power density of 5 kW·kg^-1 It also has high electrochemical performance even under bending or twisting. The all-solid-state supercapacitors can be easily integrated in series to power different commercial light-emitting diodes without an external bias voltage.

In this study, we reported our experience performing robotic extended lymph node dissection （eLND） in patients with prostate cancer. A total of 147 patients with intermediate and high-risk prostate cancer who underwent robotic eLND from May 2008 to December 2011 were included in this analysis. The dissection template extended to the ureter crossing the iliac vessels. We assessed lymph node yield, lymph node positivity, and perioperative outcomes. Lymph node positivity was also evaluated according to the number of lymph nodes （LNs） removed （〈22 vs 〉22）. The median number of LNs removed was 22 （11-51）, and 97 positive LNs were found in 24 patients （16.3%）. While the obturator fossa was the most common site for LN metastases （42.3%, 41/97）, the internal iliac area was the most common area for a single positive LN packet （20.8%, 5/24）. Eight patients （33.3%, 8/24） had positive LNs at the common iliac area. The incidence of positive LNs did not differ according to the number of LNs removed. Complications associated with eLND occurred in 21 patients （14.3%） and symptomatic lymphocele was found in five patients （3.4%）. In conclusion, robotic eLND can be performed with minimal morbidity. Furthermore, LN yield and the node positive rate achieved using this robotic technique are comparable to those of open series. In addition, the extent of dissection is more important than the absolute number of LNs removed in eLND, and the robotic technique is not a prohibitive factor for performing eLND.

Deviation between thermodynamic and experimental voltages is one of the key issues in Li-ion conversion-type electrode materials; the factor that affects this phenomenon has not been understood well in spite of its importance. In this work, we combine first principles calculations and electrochemical experiments with characterization tools to probe the conversion reaction voltage of transition metal difluorides MF2（M = Fe, Ni, and Cu）. We find that the conversion reaction voltage is heavily dependent on the size of the metal nanoparticles generated. The surface energy of metal nanoparticles appears to penalize the reaction energy, which results in a lower voltage compared to the thermodynamic voltage of a bulk-phase reaction. Furthermore, we develop a reversible CuF2 electrode coated with NiO. Electron energy loss spectroscopy （EELS） elemental maps demonstrate that the lithiation process mostly occurs in the area of high NiO content. This suggests that NiO can be considered a suitable artificial solid electrolyte interphase that prevents direct contact between Cu nanoparticles and the electrolyte. Thus, it alleviates Cu dissolution into the electrolyte and improves the reversibility of CuF2.

A burnup calculation has been performed to evaluate heavy rare earth （terbium--Tb, dysprosium--Dy） production in spent gadolinium oxide （Gd203） installed as a BP （burnable poison）. Each amount of Tb and Dy production derived from the BP has been about 30-40 times larger than those created in FP （fission products）. Required cooling time to achieve exemption level on radioactivity concentration produced Tb and Dy derived from the BP are much shorter （BP-Tb： 7.9y, BP-Dy：〈 0.1y） than those created in FP （FP-Tb： 3,616y, FP-Dy： 6.9y）. However, the BP is mixed homogeneously with UO2 pellet in current nuclear fuel system of LWRs （light water reactors）, and hence mixing of FP cannot be not avoided. In such a mixture case, the required cooling time of recovered Tb will become 2,653y and that of recovered Dy be 4.8y. For this reason, recovered Tb is unlikely to be resource for utilization, while recovered Dy must be the resource provided the precise separation from the other FP.

The feasibility of rhenium （Re） production by irradiating tungsten （W） metal in a medium size fast reactor was evaluated by using a Monte Carlo code. The fast reactor can produce about 50 kilograms of Re per every 3 years, which corresponds 10% of Japanese domestic production. The specific activity of Re can be reduced below the exemption level or even the natural Re level if W and osmium is separated after the irradiation. The use of ZrD1.7 moderator reduces the specific activity by half compared to that of ZrH1.7 case, and even the no moderator case is permissible to produce the production of Re which has lower specific reactivity than that of natural Re.

Chemical property of honey from Echium vulgare was investigated. In comparison with other honey species, the con-tents of total phenolic compounds and total flavonoids were the highest. α-Amylase activity was also extremely high: about three to nine hundred times as much as those of other honey species. The antioxidative activity of honey was investigated using four different methods. Honey from E. vulgare showed the best performance in inhibiting lipid peroxidation and scavenging superoxide anion radicals, hydroxyl radicals, and DPPH radicals. Moreover, it exhibited stronger inhibition activity of ACE. It is known that higher antioxidative activity and scavenging activity against active oxygen species in honey species related to their colour. In the present study, however, it suggests that the phenolics in honey from E. vulgare with yellow gold colour might be the major active component responsible for the strong antioxidative activity and radical scavenging activity.

Collagen from tendon of Yezo sika deer was prepared by limited pepsin digestion. The yield of collagen was very high;35.7% on the basis of lyophilized dry weight. The secondary structure of this collagen was different from that of porcine skin by ATR-FTIR analysis, although it was the same characteristics, e.g. SDS-PAGE, subunit composition, ther-mal behavior, as porcine collagen. Since taking up a problem of bovine spongiform encephalopathy infection in land animals such as calf or bovine, collagen from aquatic materials has been used in various industries. However, the present study indicates that tendon of Yezo sika deer as by-product of meat industry will have potential as an important collagen source for use in the foods, cosmetics, and medical fields.

Mungbean （Vigna radiata （L.） Wilczek） is a unique species in its ability to fix atmospheric nitrogen, with early maturity, and relatively good drought resistance. We used 454 sequencing technology for transcriptome sequencing. A total of 150 159 and 142 993 reads produced 5 254 and 6 374 large contigs （〉_500 bp） with an average length of 833 and 853 for Sunhwa and Jangan, respectively. Functional annotation to known sequences yielded 41.34% and 41.74% unigenes for Jangan and Sunhwa. A higher number of simple sequence repeat （SSR） motifs was identified in Jangan （1 630） compared with that of Sunhwa （1 334）. A similar SSR distribution pattern was observed in both varieties. A total of 8 249 single nucleotide polymorphisms （SNPs） and indels with 2 098 high-confidence candidates were identified in the two mungbean varieties. The average distance between individual SNPs was -860 bp. Our report demonstrates the utility of transcriptomic data for implementing a functional annotation and development of genetic markers. We also provide large resource sequence data for mungbean improvement programs.

Introduction: It was recently reported that candesartan, an angiotensin II receptor blocker, had a protective effect against cardiovascular events, comparable to that of calcium channel antagonists. Moreover, a renoprotective effect and anti-diabetic action of candesartan had also been demonstrated. However, whether the renoprotective effect of candesartan, especially in diabetes, was dose-dependent or not remain to be fully elucidated. The present study attempted to clarify the dose effect of renoprotection by candesartan in Japanese type 2 diabetic patients. Subjects and Method: In this case series study, we recruited 26 type 2 diabetic patients with albuminuria whose blood pressure did not reach the target BP level (<130/80 mmHg) despite administration of 4 or 8 mg/day of candesartan. Subsequently, these lower doses of candesartan were increased to the maximal dose in Japan, 12 mg/day. Clinical parameters were examined before, at 6 and 12 months after the increase in dose. Results: An ameliorating effect of the increased dose of candesartan on albuminuria and hypertension was distinctly observed. No severe adverse effect was observed. Conclusion: It was highly possible that the maximal dose of candesartan provided more effective renoprotection in hypertensive type 2 diabetic patients initially treated with lower doses of candesartan.
