Intravascular US: Applications in Interventional Radiology.

Interventional radiology applications of intravascular US (IVUS) continue to expand, complementing intraprocedural angiography and providing a unique vantage from which to guide endovascular interventions. Vascular pathologic conditions become sonographically visualized rather than inferred from the planar appearance of the opacified vascular lumen. Perivascular targets become sonographically visualized rather than approximated on the basis of fluoroscopic landmarks.

Left upper lobe and lingula torsion after transplantation of single lung with complete major and minor fissures: A case report.

Background: Native lung torsion is rare and torsion in a lung transplant is even rarer.

Case Presentation: Here we report a case of left upper lobe (LUL) and lingula torsion in a patient with a unilateral left lung transplantation. The transplant was complicated by a graft with a short pulmonary artery cuff, which required significant vascular reconstruction and manipulation.

Peripancreatic Fluid Collections After Pancreas Transplant: Safety and Efficacy of Percutaneous Drainage.

The purpose of this study was to evaluate the safety and efficacy of percutaneous drainage of peripancreatic fluid collections after pancreas transplant and to determine factors predicting a successful clinical outcome. This single-center retrospective study included 28 patients who underwent percutaneous drainage for peripancreatic collections after transplant between January 2008 and December 2018. Clinical success was defined as drainage resulting in resolution of symptoms.

Management of Indiana pouch stones through a percutaneous approach: A single center experience.

Objective: We present our experience of the treatment of reservoir stones using a percutaneous approach in patients with Indiana pouch urinary diversions.

Material And Methods: Patients who were treated percutaneously for Indiana pouch reservoir stones between January 2008 and December 2018 were identified from the hospital database, and their data were retrospectively analyzed. Patient charts were reviewed for stone burden, surgery details, and postoperative complications.

Complex Inferior Vena Cava Filter Retrieval Complicated by Migration of Filter Fragment into the Aorta and Subsequent Distal Embolization.

In 2005, a 48-year-old man with a spinal cord injury had an inferior vena cava filter placed for recurrent deep vein thrombosis and pulmonary embolism. He was referred for filter retrieval after a computed tomography scan demonstrated caval stenosis and 2 fractured filter arms, 1 in a pulmonary artery and 1 penetrating into the retroperitoneum and impinging on the aorta. During retrieval, 1 arm was inadvertently advanced into the aorta, and embolization of the arm occurred to the left profunda femoris artery.

Communication with the exon-junction complex and activation of nonsense-mediated decay by human Upf proteins occur in the cytoplasm.

The nonsense-mediated mRNA decay (NMD) pathway rids eukaryotic cells of mRNAs with premature termination codons. There is contradictory evidence as to whether mammalian NMD is a nuclear or a cytoplasmic process. Here, we show evidence that NMD in human cells occurs primarily, if not entirely, in the cytoplasm.
