Innate lymphoid cells (ILCs) of the ILC22 type protect the intestinal mucosa from infection by secreting interleukin 22 (IL-22). ILC22 cells include NKp46(+) and lymphoid tissue-inducer (LTi)-like subsets that express the aryl hydrocarbon receptor (AHR). Here we found that Ahr(-/-) mice had a considerable deficit in ILC22 cells that resulted in less(More)
We set out to better understand the signal transduction pathways that mediate liver tumor promotion by 2,3,7,8-tetrachlorodibenzo-p-dioxn ("dioxin"). To this end, we first employed congenic mice homozygous for either the Ahr(b1) or Ahr(d) alleles (encoding an aryl hydrocarbon receptor (AHR) with high or low binding affinity for dioxin, respectively) and(More)
OBJECTIVE This study determined the effect of vascular occlusion on radiofrequency lesion shape, volume, and temperature in a porcine liver model. SUBJECTS AND METHODS Radiofrequency lesions (n = 33) were created in the livers of six domestic pigs in vivo using a multiprong radiofrequency electrode. Lesions were randomly assigned to one of four vascular(More)
The aryl hydrocarbon receptor (AHR) is a transcription factor that responds to diverse ligands and plays a critical role in toxicology, immune function, and cardiovascular physiology. The structural basis of the AHR for ligand promiscuity and preferences is critical for understanding AHR function. Based on the structure of a closely related protein HIF2α,(More)

INTRODUCTION Elective surgery for diverticulitis has evolved over the last decade. We aimed to evaluate the impact of changing practice patterns on postoperative outcomes. We hypothesized that the increased use of laparoscopy, and other management changes, would correlate with a decrease in postoperative complications. METHODS Patients undergoing(More)
