Representations Of The Body In British Science-Fiction Novels From The Late Nineteenth To The Early Twentieth Century: A Study Of Edward Bulwer-Lytton's The Coming Race, H.G. Wells' The Time Machine And Aldous Huxley's Brave New World, Kornnop Jaroenvong
Chulalongkorn University Theses and Dissertations (Chula ETD)
Many critics have suggested that most of the non-human characters in late-Victorian British science-fiction novels reflect social alienation and the cultural fear of physical, mental and moral degeneration. However, by relying on the concept of critical posthumanism in the twentieth and twenty-first centuries that attempts to debunk anthropocentrism and emphasise the significance of non-human otherness, this thesis studies representations of the body in three British science-fiction novels: Edward Bulwer-Lytton's The Coming Race (1871), H.G. Wells' The Time Machine (1895) and Aldous Huxley's Brave New World (1932), which provide speculative visions of what humans will be in the future. It demonstrates …

Biological Effects Of Epigallocatechin Gallate During The Protection Of The Submandibular Gland After Injury, Erni Sulistiyani
Biological Effects Of Epigallocatechin Gallate During The Protection Of The Submandibular Gland After Injury, Erni Sulistiyani
Chulalongkorn University Theses and Dissertations (Chula ETD)
Background: When radiotherapy is delivered to head and neck cancer (HNC) patients, the salivary gland (SG) secretory epithelia can be irreversibly injured in up to 60% of the individuals, leading to dry mouth or xerostomia. Radiotherapy’s effectiveness in suppressing HNC growth is correlated with an increase in free radicals that produce DNA damage to the tumor and neighboring organs like the SG. Epigallocatechin gallate (EGCG) is one of the most abundant polyphenols present in green tea leaves and a well-known antioxidant. In previous in vitro study using genetically modified immortal SG cell lines, EGCG protected SG cells from γ-radiation. However, …
The Immunomodulatory Roles Of Supracrestal Gingival Connective Tissue-Derived Human Mesenchymal Stromal Cells In The Polarization Of Macrophages, Jirawit Inthayat
The Immunomodulatory Roles Of Supracrestal Gingival Connective Tissue-Derived Human Mesenchymal Stromal Cells In The Polarization Of Macrophages, Jirawit Inthayat
Chulalongkorn University Theses and Dissertations (Chula ETD)
MSCs exert their immunomodulatory effects on various immune cells by cell-cell contact and cytokines secretion. Our previous study has demonstrated that supracrestal gingival connective tissue-derived mesenchymal stem cells (SG-MSCs) were recognized to be a good candidate for periodontal regeneration. SG-MSCs showed the similar potential to PDL-MSCs and held significant advantage over PDL-MSCs by which a tooth extraction is not required. In terms of immunomodulatory properties, the effect of SG-MSCs on macrophage has never been explored. This study was aimed to investigate the effects of SG-MSCs on macrophages by cocultured SG-MSCs and THP-1-derived macrophages (THP-1-MPs) in direct cell-cell contact condition. Briefly, …
Prevalence Of Enterococcus Faecalis And Candida Albicans In Teeth Requiring Endodontic Retreatment, Sopida Thipung
Prevalence Of Enterococcus Faecalis And Candida Albicans In Teeth Requiring Endodontic Retreatment, Sopida Thipung
Chulalongkorn University Theses and Dissertations (Chula ETD)
Endodontic failures are mainly caused by persistence of microorganisms in the root canal system. Enterococcus faecalis has been reported as the most commonly isolated species from root canals with endodontic treatment failure in many studies, but was not the dominant species in others. Recent studies showed that Candida albicans is found together with Enterococcus faecalis within infected root canals in a polymicrobial community and both species can form biofilm. Therefore, this study aims to investigate the prevalence of Enterococcus faecalis and/or Candida albicans in root canals requiring retreatment by using both culture-based and polymerase chain reaction (PCR) techniques, and examine …

Determinants Of Health Promotion Service Consumption In Thailand, Pimpa Vitidladda
Determinants Of Health Promotion Service Consumption In Thailand, Pimpa Vitidladda
Chulalongkorn University Theses and Dissertations (Chula ETD)
Despite being preventable, noncommunicable diseases (NCDs) rank among leading causes of death in Thailand. Four main groups of NCDs involve cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes. These chronic diseases worsen economic burden and the quality of life. To ease the burden, health promotion service is one of the tools that can directly cope with risk factors of NCDs. Therefore, increasing health promotion service consumption potentially leads to risk reduction of an individual to develop NCDs. Hence, this research aims to identify the factors influencing health promotion service consumption in Thailand along with marginal effects of each factors. The …

Chulalongkorn University Theses and Dissertations (Chula ETD)
This thesis research comprises three studies, each of which investigates the inequality of income and wealth in Thailand from 1996 to 2017 and the impact of personal income tax and taxes on real estate on that inequality. Shorrocks Index decomposition technique is applied to examine the key drivers of inequality in the country in the first two studies. In the third study, the analysis is developed under the Heckman Selection Model to estimate the effect of personal income tax policy reform on the individual. The overall results demonstrate that accrued capital gains from asset ownership are the main drivers of …
