Angioedema induced by angiotensin-converting enzyme (ACE) inhibitors is rare; however, once it occurs, it can be potentially life threatening, especially for patients with possible difficult airway. Considering the risk-benefit ratio, we must be careful in administering ACE inhibitor therapy in morbidly obese patients.Mesenchymal stem cells (MSCs) are promising candidates for the development of cell-based drug delivery systems for autoimmune inflammatory diseases, such as multiple sclerosis (MS). Here, we investigated the effect of Ro-31-8425, an ATP-competitive kinase inhibitor, on the therapeutic properties of MSCs. Upon a simple pretreatment procedure, MSCs spontaneously took up and then gradually released significant amounts of Ro-31-8425. Ro-31-8425 (free or released by MSCs) suppressed the proliferation of CD4+ T cells in vitro following polyclonal and antigen-specific stimulation. Systemic administration of Ro-31-8425-loaded MSCs ameliorated the clinical course of experimental autoimmune encephalomyelitis (EAE), a murine model of MS, displaying a stronger suppressive effect on EAE than control MSCs or free Ro-31-8425. Ro-31-8425-MSC administration resulted in sustained levels of Ro-31-8425 in the serum of EAE mice, modulating immune cell trafficking and the autoimmune response during EAE. Selleck M3814 Collectively, these results identify MSC-based drug delivery as a potential therapeutic strategy for the treatment of autoimmune diseases. KEY MESSAGES MSCs can spontaneously take up the ATP-competitive kinase inhibitor Ro-31-8425. Ro-31-8425-loaded MSCs gradually release Ro-31-8425 and exhibit sustained suppression of T cells. Ro-31-8425-loaded MSCs have more sustained serum levels of Ro-31-8425 than free Ro-31-8425. Ro-31-8425-loaded MSCs are more effective than MSCs and free Ro-31-8425 for EAE therapy.

Idiopathic dilatation of the pulmonary artery (IDPA) is a rare condition in which the pulmonary artery dilates without an obvious cause. Pulmonary artery replacement is indicated in severe cases to prevent serious complications.

A 59-year-old man was diagnosed with an IDPA of 64 mm and Kommerell’s diverticulum (aortic aneurysm located at the aberrant left subclavian artery). A computed tomography scan revealed slight compression of the aneurysm to the trachea, although not interfering with airway management. The surgical approach was a median sternotomy, and cardiopulmonary bypass was established through aortic and bicaval cannulations. The perioperative course was uneventful.

To prevent injury to the dilated pulmonary artery, a strategy for cardiopulmonary bypass and a surgical approach should be discussed beforehand. As dilatation of the pulmonary artery is often complicated by anatomic abnormalities, preoperative evaluation should be aimed at appropriate assessments using imaging modalities.

Rheumatic diseases frequently present with pulmonary involvement. All anatomic structures of the lungs can be affected. Interstitial lung diseases are characterized by asystem of patterns evident in high-resolution computed tomography (HR-CT) scanning of the lungs. The HR-CT pattern can differ between rheumatic diseases.

Systematic description of all variants and patterns of pulmonary involvement in rheumatic diseases.

Narrative review based on the current literature on the topic from the perspective of rheumatology, pulmonary diseases and radiology.

Pulmonary involvement is frequent and prognostically relevant. The summary of pulmonary involvement reveals ahigh variability of affected anatomical structures as well as patterns of interstitial diseases for inflammatory rheumatic diseases. Asynopsis of the main diagnostic findings is provided.

Every rheumatic disease presented here can be associated with pulmonary involvement. Therefore, asystematic diagnostic evaluation is mandatory at the first diagnosis as well as during follow-up. Apart from clinical findings and lung function HR-CT of the lungs is decisive for the diagnostics.

Circular RNA (hsa_circ_0001772) (circRBM33) is implicated in the tumorigenesis of cancers. Nevertheless, the role of circRBM33 in CC is indistinct. Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to evaluate the levels of circRBM33, miR-758-3p, and pumilio RNA binding family member 2 (PUM2) mRNA in tissue samples and cells. Cell proliferation, apoptosis, migration, invasion, and glycolysis were assessed using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay, flow cytometry assay, transwell assay, or special commercial kits. Relative protein levels were examined via western blotting. The targeting relationship between circRBM33 or PUM2 and miR-758-3p was verified via dual-luciferase reporter or RNA pull-down assays. The role of circRBM33 was confirmed via tumor formation experiments. CircRPPH1 and PUM2 were upregulated while miR-758-3p was downregulated in CC tissues and cells. Functionally, circRBM33 knockdown constrained tumor growth in vivo and cured CC cell proliferation, migration, invasion, glycolysis, and fostered CC cell apoptosis in in vitro. Mechanistically, circRBM33 sponged miR-758-3p to modulate PUM2 expression. MiR-758-3p inhibitor neutralized circRBM33 silencing-mediated effects on the malignant behaviors of CC cells. PUM2 elevation overturned the suppressive influence of miR-758-3p upregulation on the malignant behaviors of CC cells. CircRBM33 fostered CC advancement via absorbing miR-758-3p and upregulating PUM2, indicating that circRBM33 was a possible target for CC treatment.
