The More Severe Adverse Effect Of Alcohol In Fc Gamma Receptor Iib Deficient (Fcgrllb-/-) Lupus Mice Than In Wild-Type Due To The More Profound Responses Against Alcohol-Induced Leaky Gut, Phatcharapon Yiengwattananon
Chulalongkorn University Theses and Dissertations (Chula ETD)
Consuming alcoholic beverages is well-known to have a part in causing inflammation and obstructing the function of the digestive system, and it may lead to leaky intestines. However, the relationship between alcohol consumption and Systemic Lupus Erythematosus (SLE) remains a subject of controversy continued. In general, alcohol can promote intestinal bacterial dysbiosis and also result in endotoxin release by Gram-negative bacteria. This stimulates many immune cells to produce inflammatory cytokines in the gut. This study focuses on the inflammatory response effect of FcgRIIb-/- mice upon loss of FcgRIIb receptors in which alcohol-induced leaky gut can occur. In 8-week-old mice lacking …

Depression Classification On Privacy Protected Facial Features Data, Yanisa Mahayossanunt
Depression Classification On Privacy Protected Facial Features Data, Yanisa Mahayossanunt
Chulalongkorn University Theses and Dissertations (Chula ETD)
This thesis presents depression classification on privacy protected facial features data. Fast depression classification to help patients receive proper treatment is a method that can prevent the damage of depression. However, fast and effective depression classification is difficult because medical personnel are adequate and the time to analyze depression is long per patient. Applied artificial intelligence in the medical field can help reduce the workload of medical personnel. It is also difficult because of privacy protection. Therefore, we utilize extracted facial features from facial expressions in clinical interview videos to develop a machine learning model. The model utilizes LSTM, attention …

The Expressions Of Mhc Class I And Class Ii In Biopsy Tissues By Immunohistochemistry And The Effect Of Interferon-Gamma (Ifn-Γ) On In Vitro Established Canine Cutaneous Mast Cell Tumors, Sudchaya Bhanpattanakul
Chulalongkorn University Theses and Dissertations (Chula ETD)
Canine mast cell tumors (MCT), common skin tumors in dogs, present difficulties in treatment, emphasizing the need for effective therapeutic protocols. The cancer-immunity cycle's complex interactions between cancer and the immune system play a crucial role in tumor growth. Tumors often evade immune response by downregulating MHC expression, hindering T-cell recognition. Cancer immunotherapy is a promising approach that utilizes the patient's immune system for combating cancer. Interferon-gamma (IFN-γ), a potent immune substance, plays a crucial role in enhancing MHC expression and immune functionality, crucial for T-cell recognition and cancer cell elimination. Limited research exists on MHC expression, tumor immune response, …
Upscale Production Of Canine Adipose-Derived Mesenchymal Stem Cell-Derived Exosomes For Wound Healing In Vitro, Yudith Violetta Pamulang
Upscale Production Of Canine Adipose-Derived Mesenchymal Stem Cell-Derived Exosomes For Wound Healing In Vitro, Yudith Violetta Pamulang
Chulalongkorn University Theses and Dissertations (Chula ETD)
Mesenchymal stem cell-derived exosomes (MSC-derived exosomes) have been previously reported to enhance wound healing across different phases. However, its practical application has been hindered due to challenges regarding low productivity and the lack of efficient production protocol. Additionally, the usage of exosome-based regenerative treatments in the veterinary field remains relatively unexplored. Hence, this study aimed to address these gaps by establishing a potential upscaling protocol producing canine adipose-derived mesenchymal stem cell-derived exosomes (cAD-MSC-exosomes) and exploring their wound healing potential in vitro. To facilitate production protocol establishment, an in-house exosome-collecting media, designated as VSCBIC-3, was preliminarily developed. Building upon this foundation, …

Development Of A Latex Agglutination Test Based On Vh Antibody Fragment For Detection Of Streptococcus Suis Serotype 2, Kiratika Chidkoksung
Chulalongkorn University Theses and Dissertations (Chula ETD)
Streptococcus suis serotype 2 (S. suis 2) is an important porcine pathogen that causes diseases in both swine and humans. For rapid S. suis 2 identification, a novel latex agglutination test (LAT) based on heavy-chain variable domain antibody (VH) was developed. Firstly, the soluble 47B3 VH antibody fragment from a phage display library, in which cysteine residues were engineered at the C-terminus, was expressed in Escherichia coli. The purified protein was then gently reduced to form monomeric soluble 47B3 VH subsequently used to coat with latex beads by means of site-specific conjugation. The detection sensitivity was found to be as …
