The elderly people are prone to be affected by quality of life (QOL) by nocturia becoming the multiple times. A purpose of this study was to determine it about a factor associated with the night urination. This survey was conducted in 2015 as a cross-sectional study. Anonymous, self-administered questionnaires were used to prevent individuals from being identified. The analysis subjects were 699 elderly people with the nocturia which belonged to club of the aged 65 years or older. Those with nocturia were placed in the Nocturia-1 group if they reported experiencing nocturia once per night or in the Nocturia- ≥ 2 group if they reported experiencing nocturia two or more times per night. We analyzed the relationships between the characteristics, lower urinary tract symptoms, and opportunities to go outdoors in the Nocturia-1 and Nocturia- ≥ 2 groups based on sex using the χ2 test. In addition, to investigate the factors that influence the change from nocturia once per night to two or more times per night, we performed logistic regression analysis using the χ2 test on the characteristics and lower urinary tract symptoms that showed significant differences separately for men and women. Among the men, factors with a significant positive relation-ship were age, diabetes mellitus, lower back pain, daytime frequency, and urinary urgency. Among the women, factors with a significant positive relationship were age, requiring support 1-requiring long-term care 2, urinary urgency, and feeling of incomplete emptying. It was suggested that the life of elderly people improved by nocturia not increasing.

Androgen replacement therapy （ART） efficacy on late-onset hypogonadism （LOH） has been widely investigated in Western countries; however, it remains controversial whether ART can improve health and prolong active lifestyles. We prospectively assessed long-term ART effects on the physical and mental statuses of aging men with LOH in Japan. The primary endpoint was health-related quality of life assessed by questionnaires. Secondary endpoints included glycemic control, lipid parameters, blood pressure, waist circumference, body composition, muscular strength, International Prostate Symptom Scores （IPSS）, International Index of Erectile Function-5 （IIEF-5） scores, and serum prostate-specific antigen levels. Of the 1637 eligible volunteers, 334 patients 〉 40 years with LOH were randomly assigned to either the ART （n = 169） or control groups （n = 165）. Fifty-two weeks after the initial treatment, ART significantly affected the role physical subdomain of the short form-36 health survey （SF-36） scale （P= 0.0318）. ART was also associated with significant decreases in waist circumstance （P = 0.002） and serum triglyceride （TG）（P = 0.013） and with significant increases in whole-body and leg muscle mass volumes （P= 0.071 and 0.0108, respectively）, serum hemoglobin （P 〈 0.001）, IPSS voiding subscore （P = 0.0418）, and the second question on I IEF-5 （P = 0.0049）. There was no significant difference between the groups in terms of severe adverse events. In conclusion, in patients with LOH, long-term ART exerted beneficial effects on Role Physical subdomain of the SF-36 scale, serum TG, waist circumstance, muscle mass volume, voiding subscore of IPSS, and the second question of IIEF-5. We hope our study will contribute to the future development of this area.

The base sequence in genome was governed by some fundamental principles such as reverse-complement symmetry, multiple fractality and so on, and the analytical method of the genome structure, the “Sequence Spectrum Method (SSM)”, based on the structural features of genomic DNA faithfully visualized these principles. This paper reported that the sequence spectrum in SSM closely reflected the biological phenomena of protein and DNA, and SSM could identify the interactive region of protein-protein and DNA-protein uniformly. In order to investigate the effectiveness of SSM we analyzed the several protein-protein and DNA-protein interaction published primarily in the genome of Saccharomyces cerevisiae. The method proposed here was based on the homology of sequence spectrum, and it advantageously and surprisingly used only base sequence of genome and did not require any other information, even information about the amino-acid sequence of protein. Eventually it was concluded that the fundamental principles in genome governed not only the static base sequence but also the dynamic function of protein and DNA.

AIM: To conduct a single-stage, combined computed tomography (CT) arterial portography (CTAP) and CT arteriography (CTA) imaging operation, we used Y-shaped sheaths with 2 valves, which allowed the insertion of 2 catheters simultaneously. METHODS: Of 1254 patients who underwent abdominal angiography for transarterial embolization and/or intraarterial chemotherapy in our department from May 2002 to November 2009, 664 patients in whom Y-shaped sheaths with 2 valves were used underwent CT angiography using a combination of CTA and CTAP. The Seldinger method was used to insert a 10 cm Y-shaped short sheath with 2 valves into the femoral artery. Under radiographic guidance, a 3.2 French (Fr) catheter was placed in the celiac artery or proper hepatic artery, and a second 3.2 Fr catheter was then placed distal to the inferior pancreaticoduodenal artery of the superior mesenteric artery. CTAP was then performed followed by CTA 10 min later. Photographs were taken during the early and late phases of the ***: Insertion of 3.2 Fr catheters was not possible in 6 of 664 (0.9%) patients with strong curvature of the femoral artery and 4 of 664 (0.6%) patients with strong curvature of the abdominal aorta. In addition, performing CTAP and CTA as a single-stage combined intervention was not possible in 14 of 664 (2.1%) patients whose right hepatic artery originated from the superior mesenteric artery and in 8 of 664 (1.2%) patients whose left hepatic artery branched from the left gastric artery. There were no sheath-related complications such as those related to arterial dissection or hemostasis. CONCLUSION: Although transfers to and from the CT room were necessary for anatomically variant patients, CT angiography using the Y-shaped sheath for combined CTAP and CTA was considered useful.

The nucleotide (base) sequence of the genome might reflect biological information beyond the coding sequences. The appearance frequencies of successive base sequences (key sequences) were calculated for entire genomes. Based on the appearance frequency of the key sequences of the genome, any DNA sequences on the genome could be expressed as a sequence spectrum with the adjoining base sequences, which could be used to study the corresponding biological phenomena. In this paper, we used 64 successive three- base sequences (triplets) as the key sequences, and determined and compared the spectra of specific genes to the chromosome, or specific genes to tRNA genes in Saccharomyces cerevisiae, Schizosaccharomyces pombe and Escherichia coli. Based on these analyses, a gene and its corresponding position on the chromosome showed highly similar spectra with the same fold enlargement (approximately 400-fold) in the S. cerevisiae, S. pombe and E. coli genomes. In addition, the homologous structure of genes that encode proteins was also observed with appropriate tRNA gene(s) in the genome. This analytical method might faithfully reflect the encoded biological information, that is, the conservation of the base sequences was to make sense the conservation of the translated amino acids sequence in the coding region, and might be universally applicable to other genomes, even those that consisted of multiple chromosomes.

The purpose of the paper is to clarify the mechanism of generation and collapse of a longitudinal vortex system induced around the leading edge of a delta wing. CFD captured well characteristics of flow structure of the vortex system. It is found that the vortex system has a cone-shaped configuration, and both rotational velocity and vorticity have their largest values at the tip of the vortex and reduce downstream along the vortical axis. This resulted in inducing the largest negative pressure at the tip of the delta wing surface. The collapse of the vortex system was also studied. The system can still remain until the tip angle of 110 degrees. However, between 110 degrees and 120 degrees, the system becomes unstable. Over 120 degrees, the characteristics of the vortex are considered to have converted from the longitudinal vortex to the transverse one.

在十二烷基硫酸钠、十二烷基联苯醚二磺酸钠及辛基苯酚聚氧乙烯醚所组成的阴离子/非离子复合乳化剂存在下,用批量聚合法和半连续聚合法制备了苯乙烯(St)-对乙烯基苯磺酸钠(NaSS)二元乳液共聚物,用动态激光光散射法研究了乳胶粒的粒径与聚合工艺及NaSS加入量的关系.依次以甲醇和水为溶剂,利用索氏提取器对共聚物试样进行纯化,并利用傅里叶变换红外光谱和元素分析法对提纯后的共聚物试样进行结构及组成分析.实验结果表明,当NaSS的摩尔分数为5%～20%时,乳胶粒的粒径随NaSS加入量的增加而增大.随NaSS加入量的增加,批量聚合法共聚物中NaSS单元的含量变化较小,半连续法共聚物中NaSS单元的含量则增加.
