Publication Metadata only Vessel chronologies from teak in northern Thailand and their climatic signal(1999-01-01) Nathsuda Pumijumnong; Won Kyu Park; Mahidol University; Chungbuk National UniversityFive teak trees in northern Thailand were selected for the study of vessels in terms of dendroclimatology. The tree rings were divided into earlywood and latewood, and four parameters (average vessel area, average vessel diameter, average conductive... area, and vessel density) were measured by automatic image analysis technique to obtain 50-year (1947-1996) time series. Two questions were addressed: 1) How strongly are the vessel characteristics related to climate and 2) are these relationshipsPublication Metadata only Histological evidence of the heart and ovarian vessels in the short mackerel, Rastrelliger brachysoma(2016-04-18) Sinlapachai Senarat; Wannee Jiraungkoorskul; Jes Kettratad; Chulalongkorn University; Mahidol University© 2016 Senarat et al. Background: Limited research has been reported in the basic information about the structural organizations of heart and ovarian vessel. Hence, produced herein is the first report on the heart, aortas, ovarian blood vessel... contained four parts including the sinus venosus, the atrium, the ventricle and the bulbus arteriosus. Several vessels including arteriole, capillary, small vein and lymphatic vessel were also commonly seen among oogenic stages of the R. brachysoma. WithinPublication Metadata only Differential Expression of Methyl Jasmonate-Responsive Genes Correlates with Laticifer Vessel Proliferation in Phloem Tissue of Rubber Tree (Hevea brasiliensis)(2016-12-01) Teerawat Laosombut; Poochita Arreewichit; Kanlaya Nirapathpongporn; Paweena Traiperm; Panida Kongsawadworakul; Unchera Viboonjun; Jarunya Narangajavana; Mahidol University; Rubber Research Institute of Thailand© 2016, Springer Science+Business Media New York. Rubber tree (Hevea brasiliensis) is a pivotal source for natural rubber production. Polyisoprene is synthesized in laticifer vessels, which are developed from vascular cambium in the phloem area... of the inner bark tissue. The transcription factors and phytohormones were reported to be involved in network regulation of plant vascular tissue differentiation. Methyl jasmonate (MeJA) was reported to act as a stimulator for laticifer vessel formationPublication Metadata only An Analysis of Temperature Distribution and Ablated Volume in the 3-D FEM Tissue Model with Blood Vessel during Radio-Frequency Ablation(2020-07-27) P. Keangin; P. Rattanadecho; Mahidol University; Thammasat Universityof this research is to study the treatment of brain tumor during radio-frequency ablation with computer simulation through finite element method (FEM) for solving the problem. A three-dimensional FEM model of brain tissue with a brain tumor and blood vessel... is considered. Three types of blood vessels i.e. aorta, main veins and terminal veins are studied. The electric current equation and time-dependent bioheat transfer equation coupled with time-dependent convective blood vessel heat transfer equation are solvedPublication Metadata only In vitro vessel-forming capacity of endothelial progenitor cells in high glucose conditions(2012-03-01) Chaiwat Jiraritthamrong; Pakpoom Kheolamai; Yaowalak U-Pratya; Methichit Chayosumrit; Aungkura Supokawej; Sirikul Manochantr; Chairat Tantrawatpan; Hathaitip Sritanaudomchai; Surapol Issaragrisil; Mahidol University; Faculty of Medicine, Thammasat University)-carboxyfluorescein diacetate succinimidyl ester-labeling vessel formation assay. The EPCs were cultured in three different glucose concentrations (100, 189.5, and 295.5 mg/dl of d-glucose) representing normal control and diabetes with either good or poor glycemic... control, respectively. We found that the in vitro vessel-forming capacity was impaired in EPCs cultured in high glucose concentrations compared to normal control (43.4 ± 0.8% and 34.7 ± 0.7% vs. 50.8 ± 2.1%). We further studied expression of various genesPublication Metadata only Development of grounding device to reduce current variationin submerged arc welding process for pressure vessel fabrication(2014-01-01) Supphachan Rajsiri; Kanokporn Penpondee; Sittiphun Tuntawiroon; Mahidol University© (2014) Trans Tech Publications, Switzerland. This study developed a device to solve welding problems that occur in the manufacturing of a pressure vessel for cryogenic applications under the ASME Section VIII Division 1. The cylindrical body... of the vessel was assembled with short pre-fabricated cylinders and caps using submerged arc welding. The rotatable grounding electrode was mounted to the top half of the spherical cap. However, the relatively long distance between the welding and the electrodePublication Metadata only Instance-Based Learning for Blood Vessel Segmentation in Retinal Images(2020-01-01) Worapan Kusakunniran; Sarattha Kanchanapreechakorn; Kittikhun Thongkanchorn; Mahidol Universityretinopathy in the early stage, in order to prevent the blindness. One of the key indicators of the disease is the abnormality of blood vessels in the retina. This research paper is thus to propose the technique to automatically segment blood vessels... is extracted and used for the best distinct of blood vessel structure from the background. The morphological operators and binarization process are applied here for segmenting the blood vessels with the noise reduction using CLAHE or contrast limited adaptivePublication Metadata only Hybrid learning of vessel segmentation in retinal images(2021-01-01) Worapan Kusakunniran; Peeraphat Charoenpanich; Perapat Samunyanoraset; Sarocha Suksai; Sarattha Kanchanapreechakorn; Qiang Wu; Jian Zhang; University of Technology Sydney; Mahidol UniversityIn this paper, a novel technique of vessel segmentation in retinal images using a hybrid learning based approach is proposed. Unlike most other existing methods, a double-layer segmentation technique combining supervised and instance learning steps... is introduced to enhance a sensitivity score of segmenting retinal blood vessels. The supervised learning based approach alone may not cope with unseen patterns caused by intrinsic variations in shapes, sizes, and color intensities of blood vessels acrossPublication Metadata only Fractional flow reserve guided coronary revascularization in drug-eluting era in Thai patients with borderline multi-vessel coronary stenoses.(2011-02-01) Teeranan Angkananard; Nattawut Wongpraparut; Damras Tresukosol; Pradit Panchavinin; Mahidol University. It is a challenge to demonstrate the benefit of the FFR-guided coronary revascularization in the patient with multivessel coronary disease (MVD) in the drug-eluting era in Thai patients. Forty-nine patients with MVD (71 stenotic vessels) underwent FFR...-guided revascularization (FFR group) compared with forty-nine patients with MVD (79 stenotic vessels) underwent traditional PCI (Traditional group) on the basis of visual estimation of the stenotic lesion. PCI has been performed in the FFR group patientPublication Metadata only Prevalence of Atrial Fibrillation in Patients with Retinal Vessel Occlusion and Its Association: A Systematic Review and Meta-Analysis(2019-12-02) Jakrin Kewcharoen; Elysse S.
