To evaluate amyloid-β deposition with F-florbetaben (FB PET imaging against C-PIB PET in cognitive normal controls (NC), mild cognitive impairment (MCI), and Alzheimer's disease (AD) patients. We recruited 45 subjects (15 in each group of NC, MCI, and mild/moderate AD) who had undergone dynamic F-FBB amyloid PET imaging. For comparison study, 17 participants, including six NC, five MCI, and six AD patients, also underwent C-PIB PET imaging on separate days. Standardized uptake value ratios (SUVR) were calculated using the cere

The intestinal microbiota plays a crucial role in human health, adjusting its composition and the microbial metabolites protects the gut against invading microorganisms. Enteroaggregative E. coli (EAEC) is an important diarrheagenic pathogen, which may cause acute or persistent diarrhea (≥14 days). The outbreak strain has the potent Shiga toxin, forms a dense biofilm and communicate via QseBC two-component system regulating the expression of many important virulence factors. Herein, we investigated the QseC histidine sensor kinase
