The cardiac extracellular matrix, far from being merely a static support structure for the heart, is now recognized to play central roles in cardiac development, morphology, and cell signaling. Recent studies have better shaped our understanding of the tremendous complexity of this active and dynamic network. By activating intracellular signal ...

A growing body of evidence supports the role of redox signaling in the mechanisms of hematopoietic stem cell mobilization and homing. Cytokines and adhesion molecules control stem cell mobilization through a redox-regulated process. The FoxO-SirT network appears to be intimately involved in redox-regulated stem cell homeostasis, whereas the process of ...

Opening of mitochondrial [K.sub.ATP] channels (mito[K.sub.ATP]) has been reported to underlie protection against ischaemia-reperfusion injury induced by ischaemic preconditioning (I-PC); however, the molecular mechanisms of its antiarrhythmic effect have not been fully elucidated. We explored the involvement of phosphatidylinositol 3-kinase (PI3K)/Akt in the PC-like effect of mito[K.sub.ATP] opener diazoxide with ...

We have recently shown that vasoactive peptides such as angiotensin II (Ang II) and endothelin-1 (ET-1) increased the expression of [G.sub.i] proteins and proliferation of A10 vascular smooth muscle cells (VSMC) through MAP kinase/PI3 kinase pathways. The present study was undertaken to examine the implication of growth factor receptor activation ...

Peroxisome proliferator-activated receptors (PPAR), which are key transcriptional regulators of lipid metabolism and energy production, have been suggested to play an important role in myocardial ischaemia-reperfusion (I/R) injury. Their role in cardioprotection, however, is not yet fully elucidated. Statins have shown beneficial effects on I/R damage beyond lipid lowering, and ...

After a myocardial infarct (MI), a variety of mechanisms contribute to progressive cardiac remodeling and dysfunction. Progressive activation of central sympathoexcitatory pathways appears to depend on a neuromodulatory pathway, involving local production of aldosterone and release of endogenous ouabain-like compounds ('ouabain') possibly from magnocellular neurons in the supraoptic and paraventricular ...

The supposed role of cardiac sigma receptors is fine tuning of contractility. Sigma receptors affect several ionic channels and hence their signaling is reflected by the electrophysiological properties of the heart. Numerous ligands of sigma receptors are known to prolong the QT interval and therefore cause a variety of arrhythmias, ...

Thyrotoxicosis and primary hyperaldosteronism both cause hypokalemic periodic paralysis. Here we report a 51-year-old woman presenting with severe hypokalemia due to both thyrotoxicosis and primary hyperaldosteronism. At first presentation, she had a potassium level of 1.5 mEq/L and thyrotoxicosis due to a hot nodule, and was diagnosed as having thyrotoxic ...

A 53-year-old female patient with long-standing hypertension was evaluated for left flank pain. Abdominal CT scan revealed a 2,8 cm left adrenal mass. Metanephrine, normetanephrine and vanylmandelic acid levels in a 24-hour urine sample were increased. The levels of serum cortisol, renin, aldosteron, calcitonin, parathormone, calcium and phosphate were normal. ...

The rationale for the treatment of Cushing's disease is to normalize serum cortisol and ACTH levels, while preserving the anterior pituitary function. The treatment of choice for Cushing's disease is surgery. However, in some circumstances the patients can need further treatment modalities including reoperation, radiotherapy and medical therapy. The medical ...
