The Incidence Of Antibiotic-Resistant Staphylococcus Spp. Colonization And Infection In Children And Adults With Atopic Dermatitis, Matchima Laowansiri Jan 2019

The Incidence Of Antibiotic-Resistant Staphylococcus Spp. Colonization And Infection In Children And Adults With Atopic Dermatitis, Matchima Laowansiri

Chulalongkorn University Theses and Dissertations (Chula ETD)

Atopic dermatitis (AD) is an inflammatory skin disease characterized by chronic and recurrent eczematous rash. AD occurs in both children and adults, but children are more affected. An important aggravating factor is caused by Staphylococcus aureus (S. aureus) infection. Therefore, topical (beta-lactam, macrolides, clindamycin) and systemic (mupirocin and fusidic acid) antibiotics are essential for treatment of AD. However, frequent use of antibiotics results in an increase in the incidence of antibiotic-resistant S. aureus. Methicillin resistance S. aureus (MRSA) becomes a problem in the treatment of skin diseases. It’s found that the change from penicillin binding protein (PBP) to PBP2a with …


Conjugated Bile Acid And Sphingosine 1-Phosophate Prompt Cholangiocarcinoma Cell Growth Via Releasing Exosomes, Waad A. Alruwaili Jan 2019

Conjugated Bile Acid And Sphingosine 1-Phosophate Prompt Cholangiocarcinoma Cell Growth Via Releasing Exosomes, Waad A. Alruwaili

Theses and Dissertations

Cholangiocarcinoma (CCA) is a fatal primary malignancy that is formed in the bile ducts. Cancer-associated myofibroblasts play a crucial role in CCA proliferation and invasion. Furthermore, there is a growing interest in the role of the exosome in the interaction between the cancer-associated myofibroblasts and cholangiocarcinoma which lead to CCA growth. However how cholangiocarcinoma-derived exosome affect the cancer-associated myofibroblasts in the tumor microenvironment remain unknown. In this study, we examined whether exosome produced by cholangiocarcinoma could involve in the prompt of CCA cells growth by regulation of myofibroblast. We found that cholangiocarcinoma-derived exosome could prompt elevated α-smooth muscle actin and …


Development Of Improved Acellular Pertussis Vaccines Through Inclusion Of The Rtx Antigen Or Induction Of Mucosal Immunity, Dylan Tyler Boehm Jan 2019

Development Of Improved Acellular Pertussis Vaccines Through Inclusion Of The Rtx Antigen Or Induction Of Mucosal Immunity, Dylan Tyler Boehm

Graduate Theses, Dissertations, and Problem Reports (ETD)

Pertussis is a human respiratory disease, primarily caused by the Gram-negative pathogen Bordetella pertussis. The infection is most severe and can be life-threatening in young children and infants where it manifests as a series of paroxysmal coughs. The disease is more commonly known as whooping cough, due to the whoop omitted during a massive inspiratory effort to bring air back into the lungs. Pertussis is a toxin-mediated disease that persists due to an early release of toxins that allow that bacteria to evade the cells of the innate immune response. The inhibition of the host response continues as toxin activity …
