| 1 | Polyelectrolyte gelatin-chitosan hydrogel optimized for 3D bioprinting in skin tissue engineering显示文摘Bioprinting is a promising automated platform that enables the simultaneous deposition of multiple types of cells and biomaterials to fabricate complex three-dimensional(3D)tissue constructs.Collagen-based biomaterial used in most of the previous works on skin bioprinting has poor printability and long crosslinking time.This posed an immense challenge to create 3D constructs with pre-determined shape and configuration at high throughput.Recently,the use of chitosan for wound healing applications has attracted huge attention due to its attractive traits such as its antimicrobial properties and ability to trigger hemostasis.In this paper,we optimized polyelectrolyte gelatin-chitosan hydrogel for 3D bioprinting.Modification to the chitosan was carried out via the oppositely charged functional groups from chitosan and gelatin at a specific pH of^pH 6.5 to form polyelectrolyte complexes.The polyelectrolyte hydrogels were evaluated in terms of physical interactions within polymer blend,rheological properties(viscosities,storage and loss modulus),printing resolution at varying pressures and feed rates and biocompatibility.The polyelectrolyte gelatin-chitosan hydrogels formulated in this work was optimized for 3D bioprinting at room temperature to achieve high shape fidelity of the printed 3D constructs and good biocompatibility with fibroblast skin cells. | Wei Long Ng Wai Yee Yeong May Win Naing | 2016 | International Journal of Bioprinting2016，2，1： | 4 |
| 2 | Anti-hypercholesterolemic effect of kenaf(Hibiscus cannabinus L.)seed on high-fat diet Sprague dawley rats显示文摘Objective:To determine? the anlihypercholesterolemic effects of kenaf seed samples and compare with the commercial hypocholesterolemic drug on serum lipids profiles and malondialdehyde(MDA) level in the rat.Methods:Kenaf seed oil(KSO),microencapsulated kenaf seed oil(MKSO),kenaf seed extract(KSE) and defatted kenaf seed meal(DKSM) were prepared and phytocHemicals screening on these samples were done prior in viro study.Phenolic compounds in KSF.were quantified using high performance liquid chromatography.There were 40(divided in eight diet groups of 5) male Sprague dawley rats adapted lo normal standard diet or hypercholesterolemic diet(HD) with or without the treatment of these kenaf samples for 32 days.Results:All the kenaf samples exhibited to contain most of the major phytocliemicals.KSE possessed gallic acid,tannic acid,catechin.benzaldehyde.benzoic acid,syringic acid,sinapic acid,ferulic acid,naringin acid,and protocatechuic acid.The significant higher(P<0.05) serum total cholesterol,low density lipoprotein cholesterol and MDA levels in HD group without treatment than the normal control group suggested the hypercholesterolemia was induced by the Incorporation of cholesterol into diet.KSE exhibited higher cholesterol-lowering properties due to the significant lower(P<0.05)in serum triglycerides,total cholesterol and MDA levels.KSF showed the highest efficiency of cholesterol-lowering activity,followed by KSO.MKSO and DKSM.Conclusions:DKSM.MKSO.KSO and KSE appeared lo have comparable anti-hypercholesterolemic effect with the commercial hypocholesterolemic drug.Hence,kenaf seed could be used as an alternative natural source lo replace the synthetic hypocholosterolemic drugs. | Ng Shy Kai Tee Ai Nee Elaine Lai Chia Ling Tan Chin Ping Long Kamariah Nyam Kar Lin | 2015 | Asian Pacific Journal of Tropical Medicine2015，8，1： | 2 |

| 18 | Physics and astrophysics of strong magnetic field systems with eXTP显示文摘In this paper we present the science potential of the enhanced X-ray Timing and Polarimetry(eXTP) mission for studies of strongly magnetized objects. We will focus on the physics and astrophysics of strongly magnetized objects, namely magnetars, accreting X-ray pulsars, and rotation powered pulsars. We also discuss the science potential of eXTP for QED studies. Developed by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Sciences, the eXTP mission is expected to be launched in the mid 2020s. | Andrea Santangelo Silvia Zane Hua Feng RenXin Xu Victor Doroshenko Enrico Bozzo Ilaria Caiazzo Francesco Coti Zelati Paolo Esposito Denis González-Caniulef Jeremy Heyl Daniela Huppenkothen Gianluca Israel ZhaoSheng Li Lin Lin Roberto Mignani Nanda Rea Mauro Orlandini Roberto Taverna Hao Tong Roberto Turolla Cristina Baglio Federico Bernardini Niccolo'Bucciantini Marco Feroci Felix Fürst Ersin G??ü?
