OBJECTIVE: To test the hypothesis that loss of IL (interleukin)-19 exacerbates atherosclerosis. APPROACH AND RESULTS: Il19 -/- mice were crossed into Ldlr -/- (low-density lipoprotein receptor knock out) mice. Double knockout (dKO) mice had increased plaque burden in aortic arch and root compared with Ldlr -/- controls after 14 weeks of high-fat diet (HFD). dKO mice injected with 10 ng/g per day rmIL-19 had significantly less plaque compared with controls. qRT-PCR and Western blot analysis revealed dKO mice had increased systemic and intraplaque polarization of T cells and macrophages to proinflammatory Th 1 and M1 phenotypes, and also significantly increased TNF (tumor necrosis factor)-α expression in spleen and aortic arch compared with Ldlr -/- controls...

We herein report a patient with esophageal carcinoma accompanied by double aortic arch (DAA). The preoperative computed tomography (CT) only detected the right aortic arch, but we found the presence of DAA during the operation. The patient underwent an esophagectomy through a left thoracotomy. Preoperative three-dimensional reconstruct of CT (3D-CT) should be conducted to completely understand the anomalies of the great vessels.

Wenbin Liu, Aimin Liu
With the exploitation of offshore oil and gas gradually moving to deep water, higher temperature differences and pressure differences are applied to the pipeline system, making the global buckling of the pipeline more serious. For unburied deep-water pipelines, the lateral buckling is the major buckling form. The initial imperfections widely exist in the pipeline system due to manufacture defects or the influence of uneven seabed, and the distribution and geometry features of initial imperfections are random...

BACKGROUND AND PURPOSE: Nemaline myopathy (NEM) has been associated with mutations in 12 genes to date. However, for some patients diagnosed with NEM, definitive mutations are not identified in the known genes, suggesting that there are other genes involved. This study describes compound heterozygosity for rare variants in ryanodine receptor type 3 (RYR3) gene in one such patient. METHODS AND RESULTS: Clinical examination of the patient at 22 years of age revealed a long narrow face, high arched palate and bilateral facial weakness...

Aortic arch interruption or atresia consists in a complete loss of anatomical and luminal continuity between the ascending and descending thoracic aorta. It is usually diagnosed in newborn babies but may also be present in young children, adolescents, adults and elderly patients. In these cases, it can be congenital or more frequently acquired. This latter type of aortic arch atresia is a challenge, and surgery is usually the treatment of choice. Percutaneous approaches are also possible today. We describe a case of percutaneous aortic arch reconstruction in a 9-year-old boy...

Several congenital anomalies regarding the right (RVA) and left (LVA) vertebral artery have been described. The current paper aims to perform a systematic literature review of the variable vertebral artery (VA) origin from the aortic arch (AOA) and its branches. The incidence of these variants and the ensuing AOA branching pattern are highlighted. Atypical origin cases were found more commonly unilaterally, while LVA presented the majority of the aberrancies. The LVA emersion from the AOA (3.6%) and the RVA from the right common carotid artery (RCCA) (0...

Pressure overload left ventricular hypertrophy is a known precursor of heart failure with ominous prognosis. The development of experimental models that reproduce this phenomenon is instrumental for the advancement in our understanding of its pathophysiology. The gold standard of these models is the controlled constriction of the mid aortic arch in mice according to Rockman's technique (RT). We developed a modified technique that allows individualized and fully controlled constriction of the aorta, improves efficiency and generates a reproducible stenosis that is technically easy to perform and release...

Full-arch fixed implant-supported prostheses have shown high biologic success rates after long-term follow-up, along with technical and prosthetic complications. Adequate planning is necessary for immediate implant occlusal loading in a completely edentulous maxilla or mandible. For totally edentulous patients, the main prosthetic problem is the transfer of diagnostic information to the master cast when an immediate loading approach is used. The aim of this clinical case report is to illustrate a new prosthetic protocol for immediate implant loading in edentulous or potentially edentulous patients...
