Thromboembolic infarction caused by an unknown patent foramen ovale 30 years after VA shunt insertion: a case report and review of the literature.

Background: Ventriculoatrial shunt (VA) insertion is one of the possible surgical procedures to treat hydrocephalus. However, it is also associated with several complications such as obstruction and shunt infection as well as life-threatening complications like intraatrial thrombus or thrombosis on the distal catheter. In this case report, we share a rare case of a patient with a VA shunt, who was admitted to our hospital with a stroke.

Infective endocarditis in patients with pyogenic spondylodiscitis: implications for diagnosis and therapy.

OBJECTIVEThe incidence of patients with pyogenic spinal infection is increasing. In addition to treatment of the spinal infection, early diagnosis of and therapy for coexisting infections, especially infective endocarditis (IE), is an important issue. The aim of this study was to evaluate the proportion of coexisting IE and the value of routine transesophageal echocardiography (TEE) in the management of these patients.

High-sensitive troponin is associated with subclinical imaging biosignature of inflammatory cardiovascular involvement in systemic lupus erythematosus.

Background: Cardiovascular (CV) involvement in patients with systemic lupus erythematosus (SLE) is presumably subclinical for the major part of its evolution. We evaluated the associations between high-sensitive troponin T (hs-TropT), a sensitive marker of myocardial injury, and CV involvement using cardiac magnetic resonance (CMR).

Methods And Results: This is a two-centre (London and Frankfurt) CMR imaging study at 3.

Competition for Gβγ dimers mediates a specific cross-talk between stimulatory and inhibitory G protein α subunits of the adenylyl cyclase in cardiomyocytes.

Heterotrimeric G proteins are key regulators of signaling pathways in mammalian cells. Beyond G protein-coupled receptors, the amount and mutual ratio of specific G protein α, β, and γ subunits determine the G protein signaling. However, little is known about mechanisms that regulate the concentration and composition of G protein subunits at the plasma membrane.

Rapid recruitment of temporally distinct vascular gene sets by estrogen.

Cardiovascular disease is the leading cause of mortality for both men and women in developed countries. The sex steroid hormone estrogen is required for normal vascular physiology. Estrogen functions by binding to intracellular estrogen receptors (ER), ERalpha and ERbeta, ligand-activated transcription factors that are expressed in both vascular endothelial and smooth muscle cells.
