Comparison of Tolerance to High Moisture Conditions of the Soil Among Crop Plants: Studies on the Comparative Plant Nutrition [English Translation]

Tolerance to high moisture conditions in the soil was compared for eighteen crop species, and factors causing differences among species were studied: 1) When the moisture content of a soil was kept high, the soil air contained 10.5 - 17.5% of O2 and 5.0 - 9.8% of CO2, and the soil solution was not very high in Fe, Mn or NO2-N. 2) Cruciferae, Solanaceae, sugar beet, field bean, pea, cucumber and Chrysanthemum coronarium were very susceptible to this condition, but maize, soybean, and onion were tolerant. Rice grew better under this condition than under ordinary upland conditions. 3) Tolerance to a low O2 concentration in water culture conditions was low for Chinese cabbage, tomato, sugar beet, Chrysanthemum coronarium, and eggplant, but was high for rice, onion, Azuki bean, and red pepper. 4) Tolerance to a high CO2 concentration in water culture conditions was low for Cruciferae, tomato, Chinese cabbage, red pepper, cucumber, and pea, but it was high for rice. 5) Tolerance to high moisture in the soil correlated well with the combination of tolerances to low O2 and high CO2 concentrations in water culture conditions. 6) Some of the species tolerant to high moisture in the soil developed more roots in the surface horizon of the soil when the moisture content of a soil was excessively high than when it was normal

Removal of detergents and fats from waste water using allophane

Micelles, consisting of an anionic surfactant and a fatty acid released from fat, were removed from an aqueous phase using the ion exchange characteristics of a natural clay mineral, allophane. The UV spectral measurements revealed that the concentrations of the anionic surfactant and the fatty acid in the aqueous phase decreased and that these species were removed from the aqueous phase. The adsorption of the surfactant and the fatty acid onto the allophane was confirmed by FT-IR spectroscopy. Furthermore, this adsorption was confirmed by the adsorption of anthracene added as a probe molecule.ArticleAPPLIED CLAY SCIENCE. 47(3-4):325-329 (2010)journal articl

The patient was a 15-year 6-month female, and her chief complaint was severe nasomaxillary hypoplasia with anterior crossbite. After extraction of bilateral upper and lower third molars, the preoperative orthodontic treatment was initiated at 15-year and 7-month old. After 10-month orthodontic treatment, she received a surgery of intraoral LeFort II midfacial advancement using a piezoelectric braze. The naso-maxillary LeFort II segment was placed forward and downward by 8.0 mm using a Rigid External Distractor (RED) system, and internal rigid fixation was performed. For the mandible, the bilateral intraoral vertical ramus osteotomy was also performed, resulting in 6.0 mm mandibular setback. After 6-month of postoperative treatment, multi-bracket appliances were removed. At 7-month after surgery, the satisfactory facial profile and acceptable occlusion were obtained

A novel high-throughput (HTP) cloning strategy for site-directed designed chimeragenesis and mutation using the Gateway cloning system

There is an increasing demand for easy, high-throughput (HTP) methods for protein engineering to support advances in the development of structural biology, bioinformatics and drug design. Here, we describe an N- and C-terminal cloning method utilizing Gateway cloning technology that we have adopted for chimeric and mutant genes production as well as domain shuffling. This method involves only three steps: PCR, in vitro recombination and transformation. All three processes consist of simple handling, mixing and incubation steps. We have characterized this novel HTP method on 96 targets with >90% success. Here, we also discuss an N- and C-terminal cloning method for domain shuffling and a combination of mutation and chimeragenesis with two types of plasmid vectors

Improvement of walking ability during postoperative rehabilitation with the hybrid assistive limb after total knee arthroplasty: A randomized controlled study

Objective: We aimed to compare the efficacies of rehabilitation with the hybrid assistive limb and conventional rehabilitation after total knee arthroplasty. Materials and methods: A total of 37 consecutive patients who underwent primary total knee arthroplasty for knee osteoarthritis were enrolled. Seven patients withdrew from the study after randomization, and 30 patients (hybrid assistive limb group: n = 16; conventional group: n = 14) completed the randomized controlled trial. Patients in the hybrid assistive limb group underwent ten 20-min rehabilitation sessions with the hybrid assistive limb as well as 20-min conventional sessions over the course of 2 weeks, whereas patients in the conventional group received ten 40-min conventional sessions during the same period. The primary outcome measure was walking speed, whereas the secondary outcome measures included quadriceps strength and knee pain assessed using a numerical rating scale. The outcome measures were evaluated prior to surgery and on postoperative weeks 1, 2, and 3. Results: In the early postoperative period, rehabilitation after total knee arthroplasty with the hybrid assistive limb resulted in a significantly greater improvement in walking speed (weeks 1 and 2: p = 0.045), quadriceps strength (weeks 1 and 2; weeks 1 and 3: p < 0.0001), and numerical rating scale scores (week 1: p = 0.03) than conventional rehabilitation. Conclusion: Rehabilitation with the hybrid assistive limb after total knee arthroplasty led to greater improvements in walking speed, quadriceps strength, and pain scores than conventional rehabilitation
