Below-ground growth characteristics of 13-year-old Pinus densiflora on different contour conditions in a post-fire plantation in Samcheuk,Korea

Journal of Forestry Research 2017年第5期28卷 1007-1018页

作者： Do-Hyun Kim Sung-Jun Na Sea-Hyun Kim Ewane Basil Ewane Dae-Bong Kang Do-Hyung lee Department of Forest Resources Yeungnam University Department of Forest Genetic Resources National Institute of Forest Science

We estimated the growth volume of artificially reforested Pinus densiflora in a post-fire area on three different contour conditions by comparing and analyzing the vertical and horizontal distributions of below-ground roots on each contour. The main roots at the south-facing slope (SS) developed in a long and straight form, and those on the north-facing slope (NS) in a twisted form. The side roots developed more than the main roots on the Ridge. The depth of taproots decreased in the following order: SS > NS > Ridge. The roots on the SS developed in a pile-form root structure whereas those in the Ridge and NS developed concentrically near the root collar. The amount of root development decreased in the following order: SS > NS > Ridge. The ratio of fine roots from the whole-root development decreased in the following order: Ridge > SS > NS. These results can guide considerations of growth differences according to the planting contour conditions for future establishment of P. densiflora artificial plantations.

Electroacupuncture improves microcirculation and neuronal morphology in the spinal cord of a rat model of intervertebral disc extrusion

引用

Neural Regeneration Research 2015年第2期10卷 237-243页

作者： Dai-xun Jiang Zhi-song Lu Ge-bin Li Sheng-yong Sun Xiang Mu Peter lee Wu Chen Beijing Key Laboratory of Traditional Chinese Veterinary Medicine Beijing University of Agriculture Department of Veterinary Biochemistry Nippon Veterinary and Life Science University

Most studies on spinal cord neuronal injury have focused on spinal cord tissue histology and the expression of nerve cell damage and repair-related genes. The importance of the microcirculation is often ignored in spinal cord injury and repair research. Therefore, in this study, we established a rat model of intervertebral disc extrusion by inserting a silica gel pad into the left ventral sur-face of T13. Electroacupuncture was used to stimulate the bilateralZusanlipoint （ST36） and Neiting point （ST44） for 14 days. Compared with control animals, blood lfow in the ifrst lumbar vertebra （L1） was noticeably increased in rats given electroacupuncture. Microvessel density in the T13 segment of the spinal cord was increased significantly as well. The number of normal neurons was higher in the ventral horn of the spinal cord. In addition, vacuolation in the white matter was lessened. No obvious glial cell proliferation was visible. Furthermore, hindlimb motor function was improved signiifcantly. Collectively, our results suggest that electroacupuncture can improve neuronal morphology and microcirculation, and promote the recovery of neurological functions in a rat model of intervertebral disc extrusion.

Optimization strategies for separation of sulfadiazines using Box-Behnken design by liquid chromatography and capillary electrophoresis

引用

Journal of Central South University of Technology 2007年第2期14卷 196-201页

作者：龚文君张裕平张毅军许光日魏新军 lee Kwang-pill Henan Institute of Science and Technology Department of Chemistry Graduate School Kyungpook National University South Korea

Development of effective chromatographic or electrophoretic separation involves judicious deciding of selection of optimal experimental conditions that can provide an adequate resolution at a reasonable run time for the separation of interested components. Box-Behnken factorial design was effectively applied for the separation optimization of eight structurally related sulfonamides using capillary zone electrophorosis and reverse high performance liquid chromatography. Optimum values for volume ratio of THF to H2O in eluent, column temperature and flow rate of eluent are found as 12 to 88, 35℃ and 1.0 mL/min, respectively. Box-Behnken modified optimization model is extended to separation by capillary electrophoresis (CE). While using CE, a satisfactory separation is achieved with a minimum resolution larger than 1.0 for a separation time less than 10 min.

RANKL deletion in periodontal ligament and bone lining cells blocks orthodontic tooth movement

引用

International Journal of Oral Science 2018年第1期10卷 27-35页

作者： Chia-Ying Yang Hyeran Helen Jeon Ahmed Alshabab Yu Jin lee Chun-Hsi Chung Dana T. Graves Department of Orthodontics School of Dental Medicine University of Pennsylvania Philadelphia PA USA Department of Pedodontics School of Dental Medicine University of Pennsylvania Philadelphia PA USA

The bone remodeling process in response to orthodontic forces requires the activity of osteoclasts to allow teeth to move in the direction of the force applied. Receptor activator of nuclear factor-κB ligand(RANKL) is essential for this process although its cellular source in response to orthodontic forces has not been determined. Orthodontic tooth movement is considered to be an aseptic inflammatory process that is stimulated by leukocytes including T and B lymphocytes which are presumed to stimulate bone resorption. We determined whether periodontal ligament and bone lining cells were an essential source of RANKL by tamoxifen induced deletion of RANKL in which Cre recombinase was driven by a 3.2 kb reporter element of the Col1α1 gene in experimental mice(Col1α***+.RANKLf/f) and compared results with littermate controls(Col1α***-.RANKLf/f). By examination of Col1α***+.ROSA26 reporter mice we showed tissue specificity of tamoxifen induced Cre recombinase predominantly in the periodontal ligament and bone lining cells. Surprisingly we found that most of the orthodontic tooth movement and formation of osteoclasts was blocked in the experimental mice, which also had a reduced periodontal ligament space. Thus, we demonstrate for the first time that RANKL produced by periodontal ligament and bone lining cells provide the major driving force for tooth movement and osteoclastogenesis in response to orthodontic forces.
