Intestinal in vitro and ex vivo Models to Study Host-Microbiome Interactions and Acute Stressors.

abstract：:Molecular imaging has emerged in the past few decades as a novel means to investigate atherosclerosis. From a pathophysiological perspective, atherosclerosis is characterized by microscopic inflammation and microcalcification that precede the characteristic plaque buildup in arterial walls detected by traditional asse...
