Elongation of the vertebrate heart occurs by progressive addition of second heart field (SHF) cardiac progenitor cells from pharyngeal mesoderm to the poles of the heart tube. The importance of these cells in the etiology of congenital heart defects has led to extensive research into the regulation of SHF deployment by signaling pathways and transcription factors. However, the basic cellular fe...

During heart development the second heart field (SHF) provides progenitor cells for most cardiomyocytes and expresses the homeodomain factor Nkx2-5. We now show that feedback repression of Bmp2/Smad1 signaling by Nkx2-5 critically regulates SHF proliferation and outflow tract (OFT) morphology. In the cardiac fields of Nkx2-5 mutants, genes controlling cardiac specification (including Bmp2) and ...

Simian hemorrhagic fever (SHF) is lethal for macaques. Based on clinical presentation and serological diagnosis, all reported SHF outbreaks were thought to be caused by different strains of the same virus, simian hemorrhagic fever virus (SHFV; Arteriviridae). Here we show that the SHF outbreaks in Sukhumi in 1964 and in Alamogordo in 1989 were caused not by SHFV but by two novel divergent arter...

Public and patient involvement in social and health care has proceeded in many civil societies. Depending on the legislations on national and community levels, citizens and patients have a greater say in shaping social and health care. In Germany, the patient involvement by self-help organizations at the macro level (national level and level of federal states) has significantly developed over t...

BACKGROUND The purpose of this study was, in high-risk patients, to simultaneously estimate the effect of metabolic syndrome (MetS) on diastolic or systolic heart failure (DHF or SHF), to evaluate MetS predictive value for both outcomes. METHOD We retrospective enrolled 347 high-risk patients who were scheduled to undergo coronary angiography. They were categorized into DHF cases, SHF cases a...

The right ventricle and outflow tract of the developing heart are derived from mesodermal progenitor cells from the second heart field (SHF). SHF cells have been characterized by expression of the transcription factor Islet-1 (Isl1). Although Isl1 expression has also been reported in the venous pole, the specific contribution of the SHF to this part of the heart is unknown. Here we show that Is...

OBJECTIVE No previous experimental trials have investigated Housing First (HF) in both scattered site (SHF) and congregate (CHF) formats. We hypothesized that CHF and SHF would be associated with a greater percentage of time stably housed as well as superior health and psychosocial outcomes over 24 months compared to treatment as usual (TAU). METHODS Inclusion criteria were homelessness, ment...

OBJECTIVE To test the ability of a novel super high-flux (SHF) membrane with a larger pore size to clear myoglobin from serum. SETTING The intensive care unit of a university teaching hospital. SUBJECT A patient with serotonin syndrome complicated by severe rhabodomyolysis and oliguric acute renal failure. METHOD Initially continuous veno-venous hemofiltration was performed at 2 l/hour ul...

BACKGROUND The effect of impaired kidney function on B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) is vague. This study was performed to examine the effect of kidney dysfunction on the afore-mentioned markers and determine appropriate cutoffs for systolic heart failure (SHF). METHODS In this cross sectional study adults with estimated glomerular filtration rate (eGFR) <60...

BACKGROUND Diastolic heart failure (DHF) and systolic heart failure (SHF) are 2 clinical subsets of the syndrome of chronic heart failure that are most commonly encountered in clinical practice. METHODS AND RESULTS The clinically overt DHF and SHF appear to be 2 separate syndromes with distinctive morphologic and functional changes although signs, symptoms, and prognosis are very similar. In ...
