The Influence Of Sports Facilities' Accessibility, Motivation, And Satisfaction On Word-Of-Mouth And Re-Participation Intentions Of Athletes With Physical Disabilities, Thee Trongjitpituk Jan 2020

The Influence Of Sports Facilities' Accessibility, Motivation, And Satisfaction On Word-Of-Mouth And Re-Participation Intentions Of Athletes With Physical Disabilities, Thee Trongjitpituk

Chulalongkorn University Theses and Dissertations (Chula ETD)

More than a billion people are estimated to live with some form of disability, or about 15% of the world's population and the number is still growing. People with disabilities are less likely to participate in sports due to several physical barriers they face. In an effort to find ways to increase the sports participation rate of people with disabilities, the concept of marketing (satisfaction, word-of-mouth intention, and re-participation intention) was applied to the field of accessibility for the first time. This study consisted of three objectives: (1) to find out the dimension of sports facilities' accessibility and motivation, (2) …

The Study Of Changes In Gene Regulation Of Serotonin Signaling Pathway And Circulating Serotonin Concentration In Dogs With Pulmonary Hypertension Due To Degenerative Mitral Valve Disease, Nattawan Tangmahakul Jan 2020

The Study Of Changes In Gene Regulation Of Serotonin Signaling Pathway And Circulating Serotonin Concentration In Dogs With Pulmonary Hypertension Due To Degenerative Mitral Valve Disease, Nattawan Tangmahakul

Chulalongkorn University Theses and Dissertations (Chula ETD)

Pulmonary hypertension (PH) is an abnormal increase in pulmonary vascular pressure. In dogs, PH is commonly found secondary to degenerative mitral valve disease (DMVD), especially in small breed dogs. Serotonin, a biogenic amine playing an essential role in both physiology and abnormalities of several organs, is a vasoactive substance that has been one of the suspicious mediators for the development of PH. Both local and circulating effects of serotonin have been investigated to discover the involvement of serotonin and the pathogenesis of PH in both humans and animals. The present study aimed to investigate the local serotonin signaling in lung …

The Effect Of Maternally-Derived Antibodies Against Antibody Production In Vaccinated Piglets With Modified-Live Porcine Reproductive And Respiratory Syndrome Virus Vaccines, Sunit Mebumroong Jan 2020

The Effect Of Maternally-Derived Antibodies Against Antibody Production In Vaccinated Piglets With Modified-Live Porcine Reproductive And Respiratory Syndrome Virus Vaccines, Sunit Mebumroong

Chulalongkorn University Theses and Dissertations (Chula ETD)

The humoral antibody responses following vaccination with different lineage of modified live genotype 2 porcine reproductive and respiratory syndrome virus (PRRSV) vaccines (MLVs) were investigated. Moreover, the mortality and growth performance in pigs were observed. Twenty-four pigs with high maternally derived antibody (MDA) levels (SN titer ≥ 8) from each PRRSV positive Herd 1 and Herd 2 were allocated to the H1, H1-1, and H1-2 groups (Herd 1) and H2, H2-1, and H2-2 groups (Herd 2). Twenty-four pigs with low MDA levels (SN titer <8) were allocated to the L1, L1-1, and L1-2 (Herd 1) and L2, L2-1, and L2-2 groups (Herd 2). Twenty-four pigs from the negative herd (Herd 3) were allocated to 3 groups: N, N-1, and N-2 groups. The H1, H2, L1, L2, and N groups were unvaccinated. The H1-1, H2-1, L1-1, L2-1, and N-1 groups were vaccinated with MLV (Ingelvac® PRRS MLV) at 2 weeks of age. The 5 other groups: H1-2, H2-2, L1-2, L2-2, and N-2 groups were vaccinated with MLV2 (Prime Pac® PRRS MLV) at 2 week of age. The antibody responses were measured by ELISA and serum neutralization (SN). The mortality was not observed in all vaccinated groups. Additionally, pigs with high MDA levels from the H1 and H2 groups did not exhibit the mortality throughout the study. ADG in pigs vaccinated with each MLV1 and MLV2 was significant higher than that in unvaccinated pigs. However, pigs vaccinated with MLV2 showed the highest values of ADG. Seroconversion was observed in all vaccinated groups with no significance difference in antibody titers between pigs with low and high MDA levels. However, pigs with low MDA levels showed the earliest and highest antibody level post vaccination. The highest SN-titer against MLV1 isolate and MLV2 isolate was observed in pig from the L1-1 and L2-2 groups, respectively. The field PRRSV-2 isolates: THA_SP/RB_S1/P1/0120-18 and THA_WC/RB_F165/20-22, the SN titers against these isolates were not observed in vaccinated groups. These results indicated that MDAs might not affect the immune response post vaccination. PRRSV-2 MLVs reduced the mortality and improved growth performance of pigs in the endemically PRRSV infected herds. Although, the vaccine was changed in weaning pigs, the antibody responses were detected post vaccination in both pigs with low and high level of MDAs. Moreover, the genetic similarity between vaccine and field virus was not related to the protection. Vaccine selection should depend on the induction of immune response and protection against heterologous PRRSV infection.

Study Of Platelet Production From Megakaryocyte By Using Induced Pluripotent Stem Cell, Jaturawat Pawinwongchai Jan 2020

Study Of Platelet Production From Megakaryocyte By Using Induced Pluripotent Stem Cell, Jaturawat Pawinwongchai

Chulalongkorn University Theses and Dissertations (Chula ETD)

Thrombopoiesis is the process of platelet production from hematopoietic stem cells (HSCs). Glycoproteins (GP) Ib-IX-V that is expressed on the surface of megakaryocytes and platelets binds von Willebrand factor (VWF) plays roles in platelet production. Either the GPIb deficiency or hyper-function can cause macrothrombocytopenia, the molecular mechanisms remain unclear. In this study, the pathogenesis investigations were performed in the human induced pluripotent stem cell (hiPSC) model. CRISPR-Cas9 was used to generate the hiPSCs carrying a gain-of-function GP1BA p.M255V mutation which was described in platelet-type von Willebrand disease (PT-VWD). The GPIb deficiency hiPSCs were previously derived from a Bernard Soulier syndrome …

Synthesis Of Nanoscale Zerovalent Iron (Nzvi) Derived From Lignin Containing Wastewater For Arsenic Removal, Phoomipat Jungcharoen Jan 2020

Synthesis Of Nanoscale Zerovalent Iron (Nzvi) Derived From Lignin Containing Wastewater For Arsenic Removal, Phoomipat Jungcharoen

Chulalongkorn University Theses and Dissertations (Chula ETD)

Nanoscale zerovalent iron (nZVI) plays a significant role in environmental remediation including the removal of arsenic from groundwater and drinking water. This study synthesized modified nZVI particles in order to remove arsenic in drinking water. Reductive precipitation under various conditions was used to produce non-modified nZVI (B-nZVI) and lignin-modified nZVI using either 1 g/L lignin solution (L-nZVI) or pulp and paper wastewater (P-nZVI) as the substrate. Ferrous to borohydride molar ratio of 1:1 was found to be the most appropriate ratio for L-nZVI and P-nZVI production since lignin was incorporated into the nZVI structure the most.

Effect Of 2-(4"-Hydroxybenzyl)-5-2"-Dihydroxy-3- Methoxystilbene On Apoptosis And Autophagic Cell Death Of Lung Cancer Cells, Sucharat Tungsukruthai

Chulalongkorn University Theses and Dissertations (Chula ETD)

The shifting of autophagy, a catabolic process for cell survival, toward death could be a potential mode of anti-cancer drug action. In addition, autophagic cell death (ACD) is an alternative death mechanism in resistant malignant cancer cells. This study, we demonstrated how PE5, a stilbene compound, exhibits potent ACD-promoting activity and apoptosis in lung cancer cells that may offer an opportunity for novel cancer treatment. It was found that PE5 exerted a higher toxic effect toward cancer cells compared with its effect on normal cells. Interestingly, the cell death caused by PE5 was found to be concomitant with dramatic autophagy …
