Eukaryotic cells respond to environmental stimuli when cell surface receptors are bound by environmental ligands. The binding initiates a signal transduction cascade that results in the appropriate intracellular responses. Studies have shown that endocytosis is critical for receptor internalization and signaling activation. In the rice blast fungus Magnaporthe oryzae, a non-canonical G-protein coupled receptor, Pth11, and membrane sensors MoMsb2 and MoSho1 are thought to function upstream of G-protein/cAMP signaling and the Pmk1 MAPK pathway to regulate appressorium formation and pathogenesis...

STUDY DESIGN: Retrospective cohort analysis. OBJECTIVES: To use a large cohort of three-dimensional (3D) spinal reconstructions to create a simple mathematical formula capable of estimating 3D apical vertebral rotation (AVR) based on the correlation with routinely obtained two-dimensional (2D) measurements of scoliosis. SUMMARY OF BACKGROUND DATA: Quantification of vertebral rotation in AIS using 2-dimensional (2D) imaging is inherently challenging as the axial plane cannot be directly visualized...

Less than half of patients with a chest pain history indicative of acute coronary syndrome have a diagnostic electrocardiogram (ECG) on initial presentation to the emergency department. The physician must dissect the ECG for elusive, but perilous, characteristics that are often missed by machine analysis. ST depression is interpreted and often suggestive of ischemia; however, when exclusive to leads V1-V3 with concomitant tall R waves and upright T waves, a posterior infarction should first and foremost be suspected...

Katherine R Hulme, Jon van den Burg
INTRODUCTION: A cell salvage device is used in cardiac surgery with the aim of reducing allogeneic blood transfusion. Suction of blood from the operating field used for the device is often accompanied by diathermy smoke. There is limited published research to know if this blood is then contaminated with clinically significant levels of harmful chemicals from this smoke. Postoperative cardiac surgery patients are already physiologically vulnerable, making the optimization of salvaged blood worth considering...

Brugada syndrome (BrS) is an autosomal dominant channelopathy which is responsible for a large number of sudden cardiac deaths in young subjects without structural abnormalities. The most challenging step in management of patients with BrS is identifying who is at risk for developing malignant ventricular tachyarrhythmia (VTA). In patients with BrS, conduction delay in the right ventricular outflow tract (RVOT) causes a prominent R wave in lead aVR. This electrocardiographic parameter can be useful to detect these high-risk patients...

INTRODUCTION: Safety concerns have been one of the main reasons opposing a wider acceptance of minimal invasive extracorporeal circuits (MiECC). Following an extensive experience and a multitude of modifications, we have set out to employ a modular MiECC as a universal extracorporeal circuit. METHODS: A total of 129 cardiac surgical procedures were performed by a single surgeon in 2013. Excluding procedures done under circulatory arrest or with the potential need of such, the MiECC was utilized in almost 90% of surgeries...

REVIEW
Luc A Pierard, Raluca Dulgheru
Aortic valve disease and especially aortic stenosis (AS) is a growing cardiac pathology. Aortic valve replacement (AVR) is still the only treatment with proven benefit on survival in symptomatic patients and in patients with a left ventricular ejection fraction (LVEF) <50%. The benefit of prophylactic AVR in asymptomatic patients is still unproven. Once symptoms develop, the prognosis worsens. Exercise testing has emerged as a tool to unmask the "pseudo-asymptomatic" patients with AS (those without self-reporting symptoms), to link "exercise induced dyspnea" more confidently and more objectively to aortic valve disease and to allow for a safe "watchful waiting strategy" in "pseudo-symptomatic" patients (those with dyspnea unrelated to aortic valve disease)...

BACKGROUND: With improved survival of patients undergoing primary bioprosthetic aortic valve replacement (AVR), reoperation to relieve severe prosthetic aortic stenosis (PAS) is increasing. Timing of redo surgery in asymptomatic/minimally symptomatic patients remains controversial. Left ventricular (LV) global longitudinal strain (GLS) is a marker of subclinical LV dysfunction. In asymptomatic/minimally symptomatic patients with severe PAS undergoing redo AVR, we sought to determine whether LV-GLS provides incremental prognostic use...

Patients with moderate to severe aortic stenosis (AVA <1.3 cm(2)) who were judged, by a referring cardiologist, as asymptomatic or equivocal symptomatic from the aortic stenosis were included in the study. Patients with left ventricular ejection fraction <50% were not included. Twenty-nine percent of the referred patients were judged asymptomatic and 71% equivocal symptomatic from their valve disease. The mean age was 72 years and 90% of the patients had an AVA-index <0.6 cm(2)/m(2). By clinical evaluation in the outpatient clinic, 48% were judged as having functional limitation corresponding to NYHA≥II...
