Publication Metadata only Synthesis and investigations of mineral ions-loaded apatite from fish scale and PLA/chitosan composite for bone scaffolds(2018-06-15) Weeraphat Pon-On; Panan Suntornsaratoon; Narattaphol Charoenphandhu; Jirawan Thongbunchoo; Nateetip Krishnamra; I. Ming Tang; King Mongkuts University of Technology; Kasetsart University; Mahidol University© 2018 In this study, composite scaffolds consisting of mineral ion-loaded hydroxyapatite derived from fish scale (mHAFS) in a poly(lactic acid) (PLA)/chitosan (Chi) matrix (mHAFS@PLAChi) were fabricated by an in situ blending technique. Mineral ion loaded HAFS was successfully converted into mHAFS via the hydrothermal heating of HAFS in a SBF (simulated body fluid) solution. The composite mHAFS with PLAChi showed a compressive strength of 20 MPa and a compressive modulus of 539.88 MPa with a microporous structure. In vitro investigation showed that the UMR-106 cells adhered well and proliferated on the mHAFS@PLAChi surface. Most importantly it improved the cell viability and alkaline phosphate (ALP) activity. These findings suggest that these synthesized materials have great potential for use in bone tissue engineering.Publication Metadata only New advancement perspectives of chloride additives on enhanced heavy metals removal and phosphorus fixation during thermal processing of sewage sludge(2018-07-01) Zain Ali Saleh Bairq; Rundong Li; Yanlong Li; Hongxia Gao; Teerawat Sema; Wenchao Teng; Sunel Kumar; Zhiwu Liang; Sana'a University; Hunan University; Shenyang Aerospace University; Mahidol Universitywas beneficial for the transformation of non-apatite inorganic phosphorus (NAIP) to apatite phosphorus (AP). At 900 °C this transformation is efficient for Phosphate fixation, which is evidence that apatite phosphorus (AP) has the ability to be more stable than... non-apatite inorganic phosphorus (NAIP) at high temperature.Publication Metadata only In vitro study of the SBF and osteoblast-like cells on hydroxyapatite/ chitosan-silica nanocomposite(2011-03-12) Prapaporn Jongwattanapisan; Narattaphol Charoenphandhu; Nateetip Krishnamra; Jirawan Thongbunchoo; I. Ming Tang; Rassmidara Hoonsawat; Siwaporn Meejoo Smith; Weeraphat Pon-On; Mahidol University; Commission on Higher Educationwith calcium phosphate (CaP) which is desirable for the formation of the apatite. XRD and TEM studies showed that the HAp formed in the CSi matrix were nanometer (20-40 nm) in size. Nanocomposites of HApCSi20 processed with 20%v/v silica whisker showed a micro... hardness of 84.7 ± 3.3 MPa. Mineralization study in SBF showed the formation of apatite crystals on the HApCSi surface after being incubated for 7 days. In vitro biocompatibility, cell morphology, proliferation, and cell adhesion tests confirmedPublication Metadata only Biocomposite of hydroxyapatite-titania rods (HApTiR): Physical properties and in vitro study(2013-01-01) Weeraphat Pon-On; Narattaphol Charoenphandhu; I. Ming Tang; Jarinthorn Teerapornpuntakit; Jirawan Thongbunchoo; Nateetip Krishnamra; Kasetsart University; Mahidol University; Commission of Higher Educationshowed a core-shell structure with the titania rod as the core and the apatite as the shell. The hardness of the composites of HApTiR's whisker increased from 74.8 to 92.9 MPa as the TiR content was increased from 10 to 90 wt.%. Mineralization study... in SBF showed the formation of apatite crystals on the HApTiR's surface after 7 days of incubation. In vitro cell adhesion tests confirmed the osteoblast attachment and growth on the HApTiR's surface. The density of cells, spread and the productionPublication Metadata only Hydroxyapatite from fish scale for potential use as bone scaffold or regenerative material(2016-05-01) Weeraphat Pon-On; Panan Suntornsaratoon; Narattaphol Charoenphandhu; Jirawan Thongbunchoo; Nateetip Krishnamra; I. Ming Tang; Kasetsart University; Mahidol University) is 2.01 (Ca-rich CaP). Whereas, synthesized HA consists of sub-micron HA particle having a Ca/P ratio of 1.65. Bioactivity test shows that the FSHA forms more new apatite than does the sHA after being incubated in simulated body fluid (SBF) for 7 daysPublication Metadata only Mechanical properties, biological activity and protein controlled release by poly(vinyl alcohol)-bioglass/chitosan-collagen composite scaffolds: A bone tissue engineering applications(2014-05-01) Weeraphat Pon-On; Narattaphol Charoenphandhu; Jarinthorn Teerapornpuntakit; Jirawan Thongbunchoo; Nateetip Krishnamra; I.
