Induction Of S100a7 Expression From Mechanical Stress-Induced Human Dental Pulp Cells And Its Effect On Osteoclastogenesis, Hataichanok Charoenpong

Chulalongkorn University Theses and Dissertations (Chula ETD)

Mechanical injuries of dental pulp tissues could lead to root resorption by osteoclast/odontoclast. S100A7 has been demonstrated to involve in inflammatory processes and potentially involved in bone destruction. However, the roles of S100A7 in dental pulp have not been reported. Therefore, this this study aimed to investigate the effect of mechanical stress on S100A7 expression in human dental pulp cells (hDPCs) and to investigate the effect of S100A7 protein on osteoclast differentiation. HDPCs were stimulated with in vitro compressive loading. Cell viability was determined using MTT assay. Real-time PCR (qPCR) and ELISA were utilized to determine the mRNA and protein …


The Application Of Prostacyclin In Promoting Angiogenesis Of Dental Pulp Tissue In A Three Dimensional Organ Culture System, Sonntana Seang Jan 2017

The Application Of Prostacyclin In Promoting Angiogenesis Of Dental Pulp Tissue In A Three Dimensional Organ Culture System, Sonntana Seang

Chulalongkorn University Theses and Dissertations (Chula ETD)

Background: Dental pulp vitality can be threatened by carious or iatrogenic exposure that can lead to pulp tissue loss. The formation of a vascular network is crucial to provide a suitable environment for tissue regeneration. Thus, promoting angiogenesis is essential for successful pulpal repair in regenerative endodontics therapy. Iloprost, a prostacyclin analog, promotes vascularization in several organs such as, heart, lung, and corneal. Previously, it has been demonstrated that, iloprost induced pulpal blood flow and enhanced dentin formation in a rat mechanical pulp exposure model. However, the angiogenic effect of iloprost on the human dental pulp vasculature remains unknown. Objective: …

Differential Dendritic Cell Responses To Candida Species, Thu Nguyen Ngoc

Chulalongkorn University Theses and Dissertations (Chula ETD)

Mannan in the outermost layer of Candida cell wall may be the first molecules that interact with host dendritic cells (DCs) and activate immune responses that determine disease outcomes. However, little is known how different mannan structures of common Candida species affect DC activation and T cell responses. Thus, this work compared the effects of mannans of Candida albicans, Candida tropicalis, Candida glabrata, Candida krusei, Candida parapsilosis and Candida dubliniensis on bone marrow-derived DC (BMDC) responses in mice. C. albicans and C. tropicalis mannan could not activate DC maturation, however, they induced IFN-gamma production which consequently provoked Th1 responses. C. …

Photooxidation Of Organosulfur Compounds Catalyzed By Iodo-Bodipy Derivatives Under Visible Light Irradiation, Piyamaporn Tangkasemsamran

Chulalongkorn University Theses and Dissertations (Chula ETD)

In this work, iodo-BODIPY derivatives, I-GB, 3I-GB, I-RB, were synthesized and used as photocatalysts for oxidation of organosulfurs such as thiols and thioethers into the corresponding disulfides and sulfoxides, respectively, as well as compared with benchmark photocatalyst, rose bengal. All BODIPY derivatives were successfully synthesized in good yields (36-80%) via condensation reaction between 4-iodobenzaldehyde and corresponding pyrroles, followed by oxidation with DDQ and complexation with BF3.OEt2. Among all synthesized BODIPYs, 3I-GB and 3I-RB showed relatively low quantum yield (0.053-0.054) with high singlet oxygen generation efficiency under green LED suggesting that both of them could serve as good photocatalysts for sulfur …

Tribological Characterization Of Lapping Lubricant In Hard Disk Drive Fabrication, Sawanee Jitphayomkun Jan 2017

Tribological Characterization Of Lapping Lubricant In Hard Disk Drive Fabrication, Sawanee Jitphayomkun

Chulalongkorn University Theses and Dissertations (Chula ETD)

One of the most important processes in hard disk drive fabrication is the lapping process. As two bodies are in contact, the friction occurs, and the softer material can be worn out by the harder. By using lubricant in the lapping process, it does not only reduce the friction, but it also transfers heat and captures debris away from the surface contacts. This thesis work focused on the effects of tribological parameters toward the characteristics of lubricants, using ball-on-disk tribometer. The tribological behaviors between using different base lubricants were investigated. At the same condition as final lapping process, EG-based and …

The Inflammatory Response Of Epithelial Cell To Corrosion Products From Recast Palladium -Silver Alloy, Verapol Singkarlsiri

Chulalongkorn University Theses and Dissertations (Chula ETD)

In dentistry, there is an increase in alternative metals such as palladium or silver to add into noble metal alloys in order to improve properties and reduce cost. Apart from using other metals to replace gold or platinum, reuse is another way to save the cost. There are many studies on the recast dental alloys on mechanical properties and how many percentages of new alloys needed to add in the recasting process. It has been well accepted that amount of new and used alloys would affect the mechanical and physical properties. The biocompatibility of the alloys, however, has not been …

The Fall Of The Communist Party Of Thailand From The Chinese Perspective, Feng Cui Jan 2017

The Fall Of The Communist Party Of Thailand From The Chinese Perspective, Feng Cui

Chulalongkorn University Theses and Dissertations (Chula ETD)

The Communist movement in Thailand was part of the international communist movement. So Communism in Thailand was introduced from outside and also influenced by the outside world. The history of Communist Party of Thailand (CPT) was part of Cold War. In fact, the rise of the CPT and China's help were inseparably intertwined. Thai communists could not develop so fast without the help of China after the 1960s. However, the CPT finally failed in the 1980s due to its wrong strategy of development, internal divisions and struggles, the government's counterinsurgency, the loss of support from China, among other factors. There …
