Chulalongkorn University Theses and Dissertations (Chula ETD)

This thesis entitled 'BIOMIMICRY : FUNCTION AND AESTHETIC OF VACATION HOME IN CHONBURI' is an attempt to add an architectural element named fah lai (ฝาไหล literally translated as "flowing wall" popularly translated as "breathing wall") of Thai traditional house to the category of 'biomimicry'. This attempt is problematic because the term 'biomimicry' in architecture was invented in the 1990's much later than the Thai traditional houses. These two words, fa lai and biomimicry, belong to different cultures and different times. Moreover, the term 'biomimicry' itself has various interpretations. In this thesis, I will classify the uses of this word 'biomimicry' …

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 Jan 2020

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

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, …

Radiotherapy is the standard treatment of head and neck cancer (HNC). The radiation may affect on normal tissue and surrounding salivary gland resulting to xerostomia. Treatment of radiation-related xerostomia focuses on relieving symptoms by using saliva substitutes or saliva stimulants. Because the salivary stimulants have significant side effects, such as sweating, dizziness or increasing urge to urinate, saliva substitutes are preferable. Trehalose solution has been suggested for improve moisture in dry mouth condition and can be used as saliva substitute. The purpose of this study is to evaluate the effectiveness of 10% Trehalose solution spray to improve dry mouth condition …

Property Estimation Of Palmitoylethanolamide And Sucrose Palmitate For Process Design From Methyl Palmitate, Janetiya Wongprathed

Chulalongkorn University Theses and Dissertations (Chula ETD)

Methyl palmitate is the primary component of palm oil-based biodiesel. It is a saturated fatty acid methyl ester which has a high melting point that results in low cold flow properties of biodiesel. Besides, lack of government support may affect the revenue of biodiesel business. For that reason, the producers turn attention to using biodiesel as a raw material for the production of value-added chemicals. Initially, we selected the studied products based on the gross profit margin, production process, market demand and application. This work simulated the production of palmitoylethanolamide, sucrose palmitate and normal alkanes from methyl palmitate using Aspen …
