AIM: To assess anti-migration potential of six biliary covered self-expandable metal stents(C-SEMSs) by using a newly designed phantom model. METHODS: In the phantom model, the stent was placed in differently sized holes in a silicone wall and retracted with a retraction robot. Resistance force to migration(RFM) was measured by a force gauge on the stent end. Radial force(RF) was measured with a RF measurement machine. Measured flare structure variables were the outer diameter, height, and taper angle of the flare(ODF, HF, and TAF, respectively). Correlations between RFM and RF or flare variables were analyzed using a linear correlated ***: Out of the six stents, five stents were braided, the other was laser-cut. The RF and RFM of each stent were expressed as the average of five replicate measurements. For all six stents, RFM and RF decreased as the hole diameter increased. For all six stents, RFM and RF correlated strongly when the stent had not fully expanded. This correlation was not observed in the five braided stents excluding the laser cut stent. For all six stents, there was a strong correlation between RFM and TAF when the stent fully expanded. For the five braided stents, RFM after full stent expansion correlated strongly with all three stent flare structure variables(ODF, HF, and TAF). The laser-cut C-SEMS had higher RFMs than the braided C-SEMSs regardless of expansion ***: RF was an important anti-migration property when the C-SEMS did not fully expand. Once fully expanded, stent flare structure variables plays an important role in anti-migration.

We previously investigated the thickness of the epidermis and lengths from the skin surface to the muscle fascia and bone based on measurements taken from the ultrasonic echograms of Japanese infants aged 2, 3, 4, 5, 6, and 12 - 15 months. The appropriate needle length for intramuscular injection was 16 mm (5/8 inch) in Japanese infants at any age and site. In the present study, we examined these lengths in 21 infants with physical growth from 2 to 15 months. Average height increased from 58.5 to 73.6 cm and average body weight from 5835 to 9226 g until 15 months. The circumference of the thigh increased from 22.3 cm at 2 months to a maximum of 25.9 cm at 6 months, while that of the deltoid area was 15.2 cm at 2 months and 15.9 cm at 6 months. Subcutaneous mass (length from the skin surface to the muscle fascia) at the thigh increased between 3 and 4 months and decreased at 12 - 15 months and showed good relationship to the circumference of the thigh. Subcutaneous mass at the center of the deltoid area showed the same size until 6 months. Muscle mass (lengths from the muscle fascia to the bone) at thigh and deltoid areas remained the same until 6 months. Ultrasonic echogram is an effective tool for evaluating subcutaneous and muscle mass in young infants.

New Alleles of Rice <i>ebisu dwarf</i>(<i>d</i>2) Mutant Show both Brassinosteroid-Deficient and -Insensitive Phenotypes

引用

American Journal of Plant Sciences 2012年第12期3卷 1699-1707页

作者： Tomoaki Sakamoto Yoichi Morinaka Hidemi kitano Shozo Fujioka Bioscience and Biotechnology Center Nagoya University Nagoya Japan Faculty of Bioresources and Environmental Sciences Ishikawa Prefectural University Nonoichi Japan RIKEN Advanced Science Institute Wako Japan

ebisu dwarf (d2) is a mutant caused by mutation in a rice brassinosteroid biosynthetic enzyme gene, CYP90D2/D2, thereby conferring a brassinosteroid-deficient dwarf phenotype. Three newly isolated d2 alleles derived from a Nippon- bare mutant library (d2-3, d2-4, and d2-6) produced more severe dwarf phenotypes than the previously characterized null allele from a Taichung 65 mutant library, d2-1. Linkage analysis and a complementation test clearly indicated that the mutant phenotypes in d2-6 were caused by defects in CYP90D2/D2, and exogenous treatment with brassinolide, a bioactive brassinosteroid, rescued the dwarf phenotype of three Nipponbare-derived d2 mutants. However, the content of endogenous bioactive brassinosteroid, castasterone, and the expression of brassinosteroid-response genes indicated that partial suppression of the brassinosteroid response in addition to a brassinosteroid deficiency has occurred in the Nipponbare-derived d2 mutants. Based on these results, we discuss the possibility that wild-type Nipponbare has some defects in an unknown factor or factors related to the brassinosteroid response in rice.

AIM: To assess the usefulness of contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) for lymph node metastasis in pancreatobiliary ***: All patients suspected of pancreatobiliary carcinoma with visible lymph nodes after standard EUS between June, 2009 and January, 2012 were enrolled. In the primary analysis, patients with successful EUS-fine needle aspiration (FNA) were included. The lymph nodes were assessed by several standard EUS variables (short and long axis lengths, shape, edge characteristic and echogenicity), color Doppler EUS variable [central intranodal blood vessel (CIV) presence] and CH-EUS variable (heterogeneous/homogeneous enhancement patterns). The diagnostic accuracy relative to EUS-FNA was calculated. In the second analysis, N-stage diagnostic accuracy of CH-EUS was compared with EUS-FNA in patients who underwent surgical ***: One hundred and nine patients (143 lymph nodes) fulfilled the criteria. The short axis cut-off ≥ 13 mm predicted malignancy with a sensitivity and specificity of 72% and 85%, respectively. These values were 72% and 63% for the long axis cut-off ≥ 20 mm, 62% and 75% for the round shape variable, 81% and 30% for the sharp edge variable, 66% and 61% for the hypoechogenicity variable, 70% and 72% for the CIV-absent variable, and 83% and 91% for the heterogeneous CH-EUS-enhancement variable, respectively. CH-EUS was more accurate than standard and color Doppler EUS, except the short axis cut-off. Notably, three patients excluded because of EUS-FNA failure were correctly N-staged by ***: CH-EUS complements standard and color Doppler EUS and EUS-FNA for assessment of lymph node metastases.

Characteristics of Nutrient Salt Uptake Associated with Water Use of Corn as a Catch Crop at Different Plant Densities in a Greenhouse

引用

Pedosphere 2014年第3期24卷 339-348页

作者： D.YASUTAKE C.KIYOKAWA K.KONDO R.NOMIYAMA M.kitano M.MORI S.YAMANE M.MAEDA H.NAGARE T.FUJIWARA Agriculture Unit Research and Education Faculty Kochi University The United Graduate School of Agricultural Sciences Ehime University Faculty of Agriculture Kyushu University Graduate School of Environmental and Life Science Okayama University

Dent corn, as a catch crop used for salt removal, was cultivated at different densities, i.e., 7.3 （low density）, 59.7 （normal density）, and 119.5 plants m-2 （high density）, during a 50 d fallow period after cultivation of a commercial crop in a greenhouse, to analyze the characteristics of nutrient salt （N, K, Mg, and Ca） uptake by roots and to study the effect of plant density on the characteristics associated with crop water use. Leaf area index for the high and normal density treatments reached extremely high values of 24.3 and 14.9, respectively. These values induced higher transpiration rates that were estimated using the Penman-Monteith model with the incorporation of specific parameters for crop and greenhouse conditions. The total N, K, Mg, and Ca contents in the crop canopy at harvest were 26.8, 13.0, 1.0, and 1.7 g m-S, respectively, under the high density treatment. The dynamics of salt uptake rates for high, normal, and low density treatments were evaluated by assessing weekly changes in salt content, and were subsequently compared against the transpiration rate. A positive linear relationship was obtained between these 2 parameters for all 3 density treatments and all tested salts. Hence, higher transpiration rates caused higher salt uptake rates through water absorption. On the other hand, salt uptake efficiency per unit water use by cultivation was lower in the low density treatment. Therefore, management procedures with dense planting that induce higher transpiration rates and lower evaporation rate are extremely important for the effective cultivation of corn catch crops.
