Psychiatric remission with warfarin: Should psychosis be addressed as plasminogen activator imbalance?
Conclusion: Our findings suggest that normalization of plasminogen activator levels in the brain may induce long-term remission of psychotic symptoms. Randomized controlled studies may help clarify the role of anticoagulation in the treatment of psychosis.

Local axial compressive mechanical properties of human carotid atherosclerotic plaques—characterisation by indentation test and inverse finite element analysis
Abstract: The fibrous cap of an atherosclerotic plaque may be prone to rupture if the occurring stresses exceed the strength of the cap. Rupture can cause acute thrombosis and subsequent ischaemic stroke or myocardial infarction. A reliable prediction of the rupture probability is essential for the appropriate treatment of atherosclerosis. Biomechanical models, which compute stresses and strain, are promising to provide a more reliable rupture risk prediction. However, these models require knowledge of the local biomechanical properties of atherosclerotic plaque tissue. For this purpose, we examined human carotid plaques u...

Keloids and non-diabetic kidney disease: Similarities and the APOL1–MYH9 haplotype as a possible genetic link
Abstract: Keloids and non-diabetic kidney disease are both fibrotic processes that disproportionately affect persons of African descent. Despite similarities in these conditions, the authors identified no studies to date investigating a shared genetic etiology. MYH9 and APOL1 are in linkage disequilibrium and have both been associated with non-diabetic kidney disease. MYH9 codes for a non-muscle myosin that is involved in cell adhesion and locomotion and is known to be overexpressed in keloids. Variations in APOL1 confer resistance to subspecies of Trypanosoma brucei, which may explain why otherwise deleterious genetic alt...

Platelet-derived S100 family member myeloid-related protein-14 regulates thrombosis
Expression of the gene encoding the S100 calcium–modulated protein family member MRP-14 (also known as S100A9) is elevated in platelets from patients presenting with acute myocardial infarction (MI) compared with those from patients with stable coronary artery disease; however, a causal role for MRP-14 in acute coronary syndromes has not been established. Here, using multiple models of vascular injury, we found that time to arterial thrombotic occlusion was markedly prolonged in Mrp14–/– mice. We observed that MRP-14 and MRP-8/MRP-14 heterodimers (S100A8/A9) are expressed in and secreted by platelets from WT mice and...

Syntaxin-binding protein 5 exocytosis regulation: differential role in endothelial cells and platelets
Details of the pathophysiologic mechanisms that underlie complex disorders, such as the thrombo-occlusive events associated with myocardial infarction, stroke, and venous thromboembolism, are challenging to address. Recent advances have been made through the application of genome-wide association studies (GWAS) to identify genetic loci associated with plasma levels of procoagulant proteins and risk of thrombotic disease. GWAS have consistently identified the gene encoding syntaxin-binding protein 5 (STXBP5) in this context. STXBP5 is expressed in both endothelium and platelets, and SNPs within the STXBP5 locus have been as...

Unraveling modulators of platelet reactivity in cardiovascular patients using omics strategies: Towards a network biology paradigm
Publication date: 2013 Source:Translational Proteomics, Volume 1, Issue 1 Author(s): Anne Zufferey , Mark Ibberson , Jean-Luc Reny , Ioannis Xenarios , Jean-Charles Sanchez , Pierre Fontana Platelets play an important role in the pathogenesis and the ischemic complications of atherosclerosis. Platelets may be activated by several different agonists, promoting the release of their granule contents and subsequent aggregation and thrombus formation; this leads to ischemic events such as myocardial infarction or stroke. Aspirin, the most popular antiplatelet agent, is a cornerstone in the treatment and prevention of ischemic...

Expanding use of new oral anticoagulants.
This article compares the pharmacological properties of the NOACs with those of warfarin, describes the clinical trial data with the NOACs in the approved indications, outlines the unmet medical needs that the NOACs address, highlights the potential limitations of the NOACs, and provides guidance on the optimal use of the NOACs.

The Effect of Pre-Condition Cerebella Fastigial Nucleus Electrical Stimulation within and beyond the Time Window of Thrombolytic on Ischemic Stroke in the Rats
by Weiju Tang, Weiwei Dong, Peng Xie, Pengfei Cheng, Shunjie Bai, Yifei Ren, Gong Wang, Xiuying Chen, Chun Cui, Yuxiang Zhuang, Wen Huang Objective To investigate the effect of neurogenic neuroprotection conferred by cerebellar fastigial nucleus stimulation (FNS) and the role of PPARγ- mediated inflammation in a rat model of cerebral ischemia reperfusion. Methods After a continuous 1 hour fastigial nucleus electric stimulation, the male Sprague Dawley (SD) rats were given middle cerebral artery occlusion (MCAO) for 1, 3, 6, 9, 12 and 15 hours undergoing reperfusion with intravenous recombinant tissue plasminogen activator...

Eplerenone reduces arterial thrombosis in diabetic rats
Conclusions: Our study demonstrated the antithrombotic effect of EPL manifested by a decrease in the dynamics of thrombus formation and changes in its structure. The changes in thrombosis process were accompanied by antihaemostatic, profibrinolytic and anti-inflammatory effects. The aldosterone blockade with EPL seems to be an additional pharmacological strategy for the prevention and treatment of thrombotic disorders in diabetes.

Influence of Clinical Parameters and Anticoagulation on Intraprocedural Cerebral Microembolic Signals during Pulmonary Vein Isolation
by Robert Larbig, Ralf Dittrich, Simon Kochhaeuser, Patrick Leitz, Fatih Guener, Catharina Korsukewitz, Dirk Dechering, Christian Pott, Kristina Wasmer, Jan Schmitges, Monika Kerckhoff, Lars Eckardt, Gerold Moennig Objective We had the objective to determine the impact of clinical parameters and anticoagulation status on cerebral microembolic signals (MES) during pulmonary vein isolation (PVI) for atrial fibrillation (AF). Background Thromboembolism and stroke are the most feared complications of PVI. MES can help to evaluate embolic burden. It is unknown whether clinical parameters have an impact on embolic risk during PV...

Guest Editorial: How stress changes the brain and causes a cluster of uniquely human diseases
The goal of this manuscript is to explain how stress is critically involved in the pathophysiology of a cluster of uniquely human diseases which include migraine headaches, hypertension, metabolic syndrome (obesity), stroke, deep vein thrombosis (DVT)/pulmonary emboli (PE), auto-immune diseases, schizophrenia, post-traumatic stress disorder, Alzheimer ’s disease, and atherosclerosis. As is familiar to clinicians, some people have several of these diagnoses while other people are apparently healthy and have not a single one—the diseases tend to come as a “package deal”.
