- The study aimed to assess temperature changes in the uterus of pregnant miniature pigs during MR imaging at 3 T by using fiber-optic temperature sensors placed in different locations.
- Three imaging regimens were compared: low-SAR, normal SAR, and high-SAR, with results showing increasing temperature rises in that order.
- The study concluded that while temperature increases varied by imaging protocol, third trimester temperatures were not significantly different from those in the first or second trimesters, with cumulative increases in high-SAR imaging reaching up to 2.5°C.
Mucosal immune response depends on the surveillance network established by dendritic cells (DC), APC localized within the epithelium. Bronchial epithelial cells (BEC) play a pivotal role both in the host defense and in the pathogenesis of inflammatory airway disorders. We previously showed that the outer membrane protein A from Klebsiella pneumoniae (KpOmpA), a pathogen-associated molecular pattern (PAMP) derived from Klebsiella pneumoniae, activates BEC.

To investigate its role in lung defense, the effect of a bacterial cell wall protein, the outer membrane protein A from Klebsiella pneumoniae (kpOmpA) on bronchial epithelial cells (BEC) was evaluated on adhesion molecule expression and cytokine production. Moreover, the potential implication of this mechanism in kpOmpA-induced lung inflammation was also determined.
