Abstract:
Dental pulp represents an easily accessible autologous source of adult stem cell populations. Among them, a population named dental pulp pluripotent-like stem cells (DPPSC) has been isolated from the dental pulp of human third molars and express pluripotency markers such as OCT3/4 and SOX2. DPPSC show pluripotent-like behaviour differentiating in vitro into tissues of the three embryonic layers and being able to form teratoma-like structures. This population also represents a source of adult stem cells without the ethical controversy or safety issues that are associated with the use of embryon

Abstract:
Bone-tissue engineering is a therapeutic target in the field of dental implant and orthopaedic surgery. It is therefore essential to find a microenvironment that enhances the growth and differentiation of osteoblasts both from mesenchymal stem cells (MSCs) and those derived from dental pulp (DPSC). The aim of this research is to determine the relationship among the proteins fibronectin (FN), bone morphogenetic protein 2 (BMP2) osteopontin (OPN), tenascin C (TNC) and bone sialoprotein (BSP) and their ability to coat different types of biomaterials and surfaces to enhance osteoblast differentiat

Abstract:
The very fundamental properties of biological membranes can be understood by studying their formation. This sets a good foundation for research related to how the membranes interact with organic molecules and ions; something of great value in the quest of explaining transport phenomena through cell membranes. It is furthermore of growing interest within the pharmacological research and contributes to the apprehension of life at the molecular level. In this thesis Molecular Dynamics has been used to simulate how evenly distributed phospholipids solvated in water leads to the formation of monola

Abstract:
Les fluorophores organiques absorbant et émettant dans le proche infrarouge (700-900 nm, première fenêtre thérapeutique NIR-I) sont des outils de choix pour une application en bioimagerie. En effet, l'absorption, la diffusion et l'autofluorescence de constituants du milieu biologiques sont limitées dans cette région spectrale, rendant les tissus relativement transparents à ces longueurs d'onde. Les bactériochlorines sont des dérivés de porphyrines dont deux doubles liaisons sont réduites. Ces molécules présentent une forte absorption et une émission dans le NIR-I. Les DPP sont des fluorophores

Ce travail de thèse s'inscrit dans le cas d'un projet européen nommé " microfluiD ". Ce projet vise principalement la détection des polluants organiques par voie microfluidique (les micotoxines dans les aliments de bétail, les bactéries et les métaux lourds). Devant les dangers écologiques des ions Pb2+, Hg2+ et Cd2+ dans l'environnement, il est important de multiplier le nombre d'analyses dans les eaux du robinet. L'utilisation de la fluorescence et des microlasers organiques présente de nombreux avantages. Outre leur faible coût, leur sensibilité ainsi que leur sélectivité, il est possible d

碩士<br>國立成功大學<br>化學工程學系<br>87<br>This study investigated the behavior of mixed DPPC/cholesterol monolayers and mixed DPPC/DHDP monolayers at the air/liquid interface at 37 . For DPPC/cholesterol mixed system at the air/water interface, the measurements of surface pressure-area per molecule (P-A) isotherms and relaxation curves were carried out. In the thermodynamic analysis of the mixed monolayers, the areas of monolayers exhibited negative deviations from the ideal values at all compositions for lower surface pressures. However, at higher surface pressures, distinctively positive deviations

碩士<br>國立成功大學<br>化學工程研究所<br>85<br>The hysteresis behavior of air/protein solution interface with or without DPPC monolayer is studied. The air/protein solution interface shows reproducible hysteresis behavior, which implies that both γ-globulin and lysozyme molecules have good respreading ability, and also indicates the characteristics of the slow desorption and fast readsorption behavior of proteins. As tile DPPC monolayer is spread on the air/protein solution interface, the surface pressure jumps immediately and slowly decreases to reach an equilibrium value. The typical collapse behavior

Abstract:
In an effort to re-establish tissue with odontogenic potential in the pulp space of immature permanent teeth, stimulated human dental pulp stem/progenitor cells (hDPSCs) have shown potential to differentiate and form mineralized matrix, marked by high expression of dentin sialophosphoprotein (DSPP) and osteocalcin (OCN). Bacterial by-products have been shown to adversely affect cell differentiation. This study investigated the effect of P. gingivalis, a putative endodontic pathogen, and blockage of its host recognition on hDPSCs. Stimulated hDPSCs were exposed to varying concentrations of P. g

The lipid rafts contain 3 to 5-fold the amount of cholesterol found in the surrounding bilayer. Like cholesterol in mammalian cell membrane, ergosterol is important to the raft in the yeast cell membrane. To gain a better understanding of the effect of sterols on biological membrane properties requires investigations of the phase behavior.

DPPC and PA are the main compositions of human pulmonary surfactants that contribute to the surface tension-lowering ability of pulmonary surfactants. Previous studies indicated that DPPC alone cannot substitute natural pulmonary surfactant to restore the normal function of a lung because the DPPC monolayer is unstable over its dynamic compression–expansion cycle. A LB film balance system was utilized to monitor the dynamic surface pressure-area iso
