Intestinal wall necrosis without perforation was produced in six dogs. Another group of three dogs served as a control. The histologic findings, the degree of ischemia and scintigraphic images obtained after the infusions of autologous white blood cells labelled with indium-111 oxine were correlated. Positive scans were obtained in all the dogs with proven intestinal ischemia. Negative scans appeared in the dogs without ischemic insult and a false-positive scan were observed in a control dog with diarrhea.

A rare autopsy case of malignant transcription factor E3 (TFE3)-rearranged perivascular epithelioid cell tumor (PEComa)-like neoplasm is presented. An 84-year-old woman manifested multiple cerebral infarctions and repetitive embolic events in the supra mesenchymal artery (SMA), and the presence of a mobile mass in the heart's left ventricle was also revealed. Tumoral lesions were also found in a pelvic space and a right pleural cavity, and a biopsy was performed from one of the disseminated tumor masses in the right pleura.

The duodenal diverticulum is a relatively frequent entity whose diagnosis has been increased over time with the development of new diagnostic and exploratory techniques. Periampullary diverticula (PAD) were classified as type 1, 2, or 3 according to the position of the major papilla from the endoscopic view: type 1, the major papilla was located inside of the diverticula; type 2, the major papilla was located at the edge of the diverticula; type 3, the major papilla was located outside of the diverticula. Complications of duodenal diverticula include ulceration, bleeding, perforation and inflammation with intestinal obstruction.

Elevated inflammatory markers on blood tests and emergent computed tomography led to a diagnosis of acute mesenteric ischemia, and the patient passed away 7 h later. Skin mottling indicates decreased blood flow in the gastrointestinal tract and is observed during mesenteric ischemia.

Department of Medical Imaging, Second Hospital of Hebei Medical University, Shijiazhuang, China.
Background: Fetal midgut volvulus is a rare disease, with a high risk of potentially life-threatening fetal complications.
Purpose: The aim of this study was to retrospectively analyze the imaging findings of fetal midgut volvulus diagnosed by magnetic resonance imaging (MRI) and explore its value in non-invasive prenatal diagnosis.
Methods: A retrospective collection of data from 156 fetuses suspected of intestinal obstruction by ultrasound examination in our hospital was conducted.
The role of ferroptosis in liver injury after cold ischemia-reperfusion in rats with autologous orthotopic liver transplantation.

Using autologous orthotopic liver transplantation (AOLT) model in rats, the effect of lipid reactive oxygen species (L-ROS) inhibitor Ferrostain-1 on ferroptosis signal pathway was observed to determine whether ferroptosis occurred in rat liver injury after cold ischemia-reperfusion (I/R). Thirty-two healthy adult SPF male SD rats, 8 ~ 10 weeks old, weight 240 ~ 260 g, were divided into four groups by the method of random number table (n = 8): sham group, I/R group, I/R + Fer-1 group, I/R + DFO group. In the I/R + Fer-1 group, ferristatin-1(5 mg /kg) was intraperitoneally injected 30 min before surgery; in the I/R + DFO group, DFO 100 mg/kg was injected intraperitoneally 1 h before operation and 12 h after operation.
