In the present study, follicle-sinus complexes (FSCs) were harvested from the muzzle skin of 123 dogs with suspected canine rabies, and the sensitivity and specificity of FSC analysis were compared with those of brain tissue immunohistochemistry analysis. In the FSCs, viral antigen was detected from Merkel cells. Sensitivity was 97.3%, specificity was 100%, and the coefficient κ was 0.88. These results reconfirm that FSCs are very useful for the postmortem diagnosis of canine rabies, and suggest that 5 FSCs can yield results that are almost equivalent to those derived from brain tissue analysis in rabid dogs.

Background: Severe abdominal aortic calcification (AAC) points to high cardiovascular risk and leptin stimulates arterial calcification; however, clinical data on their association are scarce. We studied the link between serum leptin and AAC severity and progression, and the effect of smoking and lipid levels, on this association in men. Methods and Results: At baseline, 548 community-dwelling men aged 50–85 years underwent blood collection and lateral lumbar spine radiography. In 448 men, X-ray was repeated after 3 and 7.5 years. AAC was assessed using Kauppila’s semiquantitative score. In multivariable models, high leptin was associated with higher odds of severe AAC (odds ratio [OR]=1.71 per SD, 95% confidence interval [CI]: 1.22–2.40). The odds of severe AAC were the highest in men who had elevated leptin levels and either were ever-smokers (OR=9.22, 95% CI: 3.43–24.78) or had hypertriglyceridemia (vs. men without these characteristics). Higher leptin was associated with greater AAC progression (OR=1.34 per SD, 95% CI: 1.04–1.74). The risk of AAC progression was the highest in men who had elevated leptin levels and either were current smokers or had high low-density lipoprotein-cholesterol levels (OR=5.91, 95% CI: 2.46–14.16 vs. men without these characteristics). These links remained significant after adjustment for baseline AAC and in subgroups defined according to smoking and low-density lipoprotein-cholesterol levels. Conclusions: In older men, high leptin levels are associated with greater severity and rapid progression of AAC independent of smoking, low-density lipoprotein-cholesterol or triglycerides.

The postharvest physiology of cut astilbe inflorescences (Astilbe × arendsii), which consist of many small florets with a short vase life, was studied in response to treatments to extend their vase life. Exogenous ethylene treatment at 0.3 μL·L−1 for 7 h did not affect the senescence of inflorescences or leaves of five cultivars and 0.2 mM silver thiosulfate for 2 h did not improve the quality of inflorescences of three cultivars, which indicated that ethylene is not a critical factor for senescence in astilbe florets. Continuous treatment with 2% sucrose or 2% trehalose solutions prolonged the cut inflorescence vase life of one or two of five astilbe cultivars, respectively. Pulse treatment with 2% trehalose in combination with 6% sucrose increased total soluble sugar contents from 11.4 to 57.6 mg·g−1 FW and raised the respiration rate of inflorescences from 15.3 to 28.4 μmol CO2·h−1·g−1 FW at 2 days after harvest (DAH) in the cultivar ‘Gloria Purpurea’. However, the effects of pulse treatment diminished at 4 DAH and extended the vase life from 4.0 days to a maximum of 5.6 days, which suggested that pulse treatments were inadequate to maintain sugar contents and respiration activity. Continuous treatment with 6% sucrose extended the vase life from 4.3 to 10.0 days and raised the chroma (C*) value of florets from 28.7 to 54.9 at 8 DAH. Continuous treatment with 2% trehalase + 4% sucrose markedly prolonged the vase life to 11.5 days and increased the C* value to 53.9 at 8 DAH. Under stereomicroscopic observation, continuous treatment with 2% trehalase + 4% sucrose maintained more vivid pink color of petals, styles, filaments and receptacles than those in control florets at 9 DAH. Combined treatment with 2% trehalose and 30 μM validamycin A, a potent inhibitor of trehalose metabolizing activity, induced severe wilting of florets and necrotic spots on leaves. Exogenous trehalose may be hydrolyzed by trehalose metabolizing activity in cut astilbe inflorescences. The results suggest that continuous treatment with trehalose and sucrose solutions is effective to maintain development and delay senescence of florets to extend the vase life of cut astilbe inflorescences.

Two carbohydrate binding surface sites (SBSs) on barley &alpha;-amylase 1 (AMY1) of glycoside hydrolase family 13 (GH13) displayed synergy in interactions with starch granules, thus being pivotal for hydrolysis of supramolecular substrates. Mutational analysis showed that SBS1 is more critical for the conversion of starch granules, while SBS2 has higher affinity than SBS1 for &beta;-cyclodextrin (&beta;-CD). Noticeably, the binding preference of &beta;-CD to SBS2 differed distinctly from that of maltooligosaccharides to the catalytic nucleophile mutant D180A AMY1. Binding energy maps at subsites -8 through +4 of the active site indicated remarkably elevated affinity due to the Y380A mutation at SBS2. The high-yield AMY2 expression variant A42P, made it possible to show that Tyr378&mdash;corresponding to Tyr380 in AMY1&mdash;has a role in interactions with starch granules, but not in &beta;-CD binding. Besides SBSs, dedicated starch binding domains (SBDs) mediate binding to starch granules. SBDs are currently categorised into 9 carbohydrate binding module (CBM) families. A novel CBM20 subfamily encountered in regulatory enzymes possesses characteristically low affinity for &beta;-CD. Although &alpha;-amylase is essential for starch mobilisation in germinating barley seeds, efficient degradation requires the concerted action of &alpha;-amylase, &beta;-amylase, limit dextrinase (LD) and possibly &alpha;-glucosidase. Limit dextrinase (LD) is encoded by a single gene and represents the sole debranching activity during germination. Recent expression of functional LD in <i>Pichia pastoris</i> makes biochemical and biophysical characterisation of this GH13 enzyme possible. An endogenous limit dextrinase inhibitor was cloned and produced recombinantly and demonstrated to have sub-nanomolar affinity for LD.

In this paper, we report the fabrication and analysis of the gated twin-bit NAND flash memory with a nitride charge-trapping layer. This device is based on the recessed channel structure, and it has an additional cut-off gate that enables 2-bit operation. Therefore, the density of the array can be doubled without any difficulty in patterning. The fabrication method for gated twin-bit (GTB) silicon–oxide–nitride–oxide–silicon (SONOS) memories and their electrical characteristics are described in this paper. Program/erase characteristics are observed and the 2-bit operation is verified by the forward–reverse reading scheme.

Background:Adipose tissue is one of the sources of mesenchymal stem cells, which have the potential to differentiate into various types of cells, including myocytes. Whether brown adipose tissue (BAT)-derived cells might differentiate into the cardiac pacemaking-conducting cells, and have the potential to regenerate the cardiac conduction system (CCS), is investigated in this study.Methods and Results:BAT was isolated from the interscapular area of mice and enzymatically digested before culture. Round or fusiform cells showed spontaneous beating at 4–7 days after culturing of BAT-derived cells. Reverse transcriptase-polymerase chain reaction analysis and immunocytochemical analysis revealed that BAT-derived cells expressed several cardiomyocytes, the CCS and pacemaker (PM) cell marker genes and proteins. Patch-clamp techniques revealed that spontaneous electrical activity and the shape of the action potential showed properties of cardiac PM cells. Next, a complete atrioventricular (AV) block was created in mice and green fluorescent protein-positive (GFP (+)) BAT-derived cells were injected intramyocardially around the AV node. At 1 week after transplantation, 50% of BAT-derived cells injected mice showed a sinus rhythm or a 2:1 AV block. Immunohistochemical analysis revealed that injected GFP (+) cells were engrafted and some GFP (+) cells co-expressed several cardiac PM cell marker proteins.Conclusions:BAT-derived cells differentiate into the CCS and PM-like cells in vitro and in vivo, and may become a useful cell source for arrhythmia therapy.

等級の異なる10種のスケトウダラ冷凍すり身に加水して調製した加熱ゲルの破断強度(BS),破断凹み,及びゲル剛性(Gs)とタンパク質(P)濃度の関係を解析した。そして,(1)BSとGsはP濃度に伴って指数関数的に増大,(2)加水しない加熱ゲルのBSとGsの最大値はすり身の等級が上位の方が高く,(3)BS vs Gsを図示すると,10種のすり身から得た加熱ゲルの両値の間に強い正の相関があった。これらの結果は,そのBSとGsのレベルとP濃度依存性から見積る加熱ゲル形成能が,冷凍すり身の品質要因の一として有用であることを示す。From ten lots of walleye pollack frozen surimis of various grades, the heated gels of different protein concentrations were prepared by adding 0-150% water. Breaking strength (BS), breaking strain (bs), and gel stiffness (Gs=BS/bs) were measured, and the effect of the protein concentration of the heated gel on their physical values was analyzed. The results were as follows: (1) Of all the surimis tested, the BS and Gs of the heated gel increased exponentially with the increase in the protein concentration of the heated gel. (2) The maximum values of BS and Gs of the heated gels formed without addition of water were higher in the order of SA>FA>A>KA>2nd grades of frozen surimi. (3) When BS was plotted against Gs, there was a close, positive correlation among those of the heated gels from the ten lots of frozen surimis of various grades. These results indicated that the heated gel forming ability, as measured by BS and Gs levels of the heated gel and its dependence on the protein concentration, is a useful parameter for judging the quality of walleye pollack frozen surimi.

In this study, we investigated the effect of high temperature on spear sprouting and elongation in asparagus to explore new approaches to control the harvest period in asparagus production. Four-year-old rootstocks of ‘UC157’ were grown in chambers in the dark at 30°C (30°C treatment), 34°C (34°C treatment), 38°C (38°C treatment), and 42°C (42°C treatment) for 14 days, and then at 25°C for 18 days. In the 42°C treatment, no spear sprouting was detected, and all rootstocks died. During the high temperature period, the number of sprouted spears was significantly lower in the 38°C treatment than in the 30°C treatment, whereas after the high temperature periods, the number was significantly higher in the 38°C treatment than in the 30°C and 34°C treatments. The total number of sprouted spears during and after the high temperature periods was not significantly different between the 30°C, 34°C, and 38°C treatments. The elongation rate of the spears during the high temperature period was significantly lower in the 38°C treatment than in the 30°C and 34°C treatments, whereas there were no significant differences in the mean spear elongation rate after the three high temperature treatments. These results suggest that a temperature of 38°C can be used to control spear sprouting reversibly by its application and cancellation.

Two atomic bombs dropped on Hiroshima and Nagasaki in August 1945 brought the unexpected liberation of Korea from the 35-year Japanese occupation. Koreans therefore had a very favorable and positive image of the nuclear bomb and nuclear energy from the beginning. The image of the nuclear bomb as "savior" was strengthened during the Korean War when the United States openly mentioned the possible use of the nuclear bomb against North Korean and Chinese military. After the end of the Korean War in July 1953 South Koreans strongly supported the development of the nuclear bomb in order to deter another North Korean invasion. When the US government provided South Korea with a research nuclear reactor in the late 1950s, most South Koreans hailed it as the first step to developing their own nuclear bomb. This paper will analyze how and why the savior image of the nuclear bomb originated and spread in Korea during the 1950s.
