Inhibition Of Chondrocyte Apoptosis Via Fas/Fasl System In Knee Osteoarthritis Patients, Ousakorn Kamenkit Jan 2023

Inhibition Of Chondrocyte Apoptosis Via Fas/Fasl System In Knee Osteoarthritis Patients, Ousakorn Kamenkit

Chulalongkorn University Theses and Dissertations (Chula ETD)

Osteoarthritis (OA) is a degenerative rheumatic disease characterized by articular cartilage degeneration. This articular cartilage degradation is positively correlated with chondrocyte apoptosis. The Fas/Fas ligand (FasL) system is part of the extrinsic apoptosis pathway that regulates cell death through the binding of Fas on target cells to FasL on effector cells. Although Fas+ chondrocytes have been identified and the Fas/FasL system has been implicated in this apoptotic process, the apoptosis through chondrocyte-to-FasL+ cell interaction remains unclear. Therefore, this study aims to investigate Fas/FasL-mediated chondrocyte apoptosis focusing on cell-to-cell interactions. In our study, we conducted ex vivo experiments using flow cytometry …

Metagenomic Analysis Using Oxford Nanopore For Fungal Identification In Hemoculture Sample, Nattapong Langsiri

Chulalongkorn University Theses and Dissertations (Chula ETD)

Currently, with advancements in medical technology, the mortality rate from fungal infections has also increased, particularly since the late 20th century. The incidence of invasive fungal infections, especially bloodstream fungal infections, is rising. However, laboratory diagnosis of fungi from clinical specimens still faces significant limitations. Diagnosing fungi based on morphological characteristics to identify species level can take weeks, which is not aligned with the severity of the disease. Current molecular biology techniques also have limitations, such as PCR success rates and mixed infections. With significant advancements in sequencing technology leading to third-generation sequencing, there are notable benefits. Third-generation sequencing, or …

Molecular Investigation And Genetic Characterization Of Canine Astrovirus And Canine Kobuvirus With Associated Pathology In Domestic Dogs In Vietnam And Thailand, Tin Van Nguyen

Chulalongkorn University Theses and Dissertations (Chula ETD)

Canine astrovirus (CaAstV) and canine kobuvirus (CaKoV) are recently recognized pathogens associated with canine gastrointestinal disease (GID), though their exact role remains poorly understood.
