OBJECTIVE: Hypertensive disorders during pregnancy increase cardiovascular risk later in life by 2 to 9-fold. Endothelial activation is one of the underlying mechanisms of cardiovascular risk. Therefore, we decided to investigate endothelial activation in primiparous women, 2.5 years after a hypertensive pregnancy disorder. STUDY DESIGN: Plasma samples were taken from women 2.5 years after gestational hypertension (GH) or late onset preeclampsia (cases) and from women 2...

Patients with schizophrenia are predisposed toward developing cardiovascular disease. Although neuroleptics affect the cardiovascular system, it is also important to consider the consequences of the disease itself such as lower physical activity due to living on disability pension, inadequate nutrition, and/or nicotine addiction, being more common among patients with schizophrenia versus the general population. All these factors combined lead to an increased risk of death caused by cardiovascular conditions in schizophrenic patients...

The combination of a negative D-dimer and a Wells score can rule out, but not confirm, a diagnosis of deep venous thrombosis (DVT). We aimed to identify new diagnostic biomarkers for DVT and to investigate their relationship with hypercoagulability markers [D-dimer and activated protein C-protein C inhibitor (APC-PCI) complex]. We screened 92 cardiovascular-specific proteins in plasma samples from 45 confirmed DVT patients and 45 age- and sex-matched non-DVT patients selected from a prospective multicentre diagnostic management study (SCORE) by Proseek Multiplex CVDIII96×96 ...

BACKGROUND: Activated platelets release platelet extracellular vesicles (PEVs). Adenosine diphosphate (ADP) receptors P2Y1 and P2Y12 both play a role in platelet activation, The present hypothesis herein is that the inhibition of these receptors may affect the release of PEVs. METHODS: Platelet-rich plasma from 10 healthy subjects was incubated with saline, P2Y1 antagonist MRS2179 (100 µM), P2Y12 antagonist ticagrelor (1 µM), and a combination of both antagonists...

Brain death is associated with significant inflammation within the kidneys, which may contribute to reduced graft survival. Direct peritoneal resuscitation (DPR) has been shown to reduce systemic inflammation after brain death. To determine its effects, brain dead rats were resuscitated with normal saline (targeted intravenous fluid, TIVF) to maintain a mean arterial pressure of 80 mmHg and DPR animals also received 30cc of intraperitoneal peritoneal dialysis solution. Rats were euthanized at zero, two, four, and six hours after brain death...

Vascular diseases such as myocardial infarction and ischemic stroke are associated with increased platelet function whilst the risk of recurrence is reduced by antiplatelet agents such as aspirin, clopidogrel, and prasugrel. However, some patients exhibit high platelet reactivity, especially with clopidogrel. Existing platelet function tests may not be ideal in that they can be expensive, are often time consuming, and measurements must be made near to the patient and within a few hours of blood collection. Platelet activation leads to translocation of P-selectin from alpha-granules to the cell surface...

Patients successfully treated for HIV infection still have an increased risk for cardiovascular morbidity and mortality, which might be related not only to traditional risks, but also to inflammation and dyslipidemia. We examined the relationship of serum lipid levels with plasma biomarkers of inflammation using a composite inflammatory burden score (IBS) based on individual (>75th percentile) measurements from the following seven markers: CD40L, tPA, MCP-1, IL-8, IL-6, hCRP and P-selectin. IBS was categorized as 0 (none of the biomarkers >75th percentile), 1, 2 and 3 or more scores...

BACKGROUND: Extracellular vesicles (EVs) from human saliva expose coagulant tissue factor (TF). Whether such TF-exposing EVs contribute to haemostasis, however, is unknown. Recently, in a mice model, tumour cell-derived EVs were shown to deliver coagulant TF to activated platelets at a site of vascular injury via interaction between P-selectin glycoprotein ligand-1 (PSGL-1) and P-selectin. OBJECTIVES: We hypothesized that salivary EVs may deliver coagulant TF to activated platelets via interaction with P-selectin...

Telocytes (TCs) are cells with long, thin and moniliform processes called telopodes. These cells have been found in numerous tissues, including the eye choroid and sclera. Lamina fusca (LF), an anatomical structure located at the sclera-choroid junction, has outer fibroblastic lamellae containing cells with long telopodes. The purpose of this study was to evaluate, via transmission electron microscopy, the LF for the presence of endothelial-specific ultrastructural features, such as Weibel-Palade bodies (WPBs), in the residing TCs...

Macrophages play an indispensable role in the host immune defense. Macrophages can undergo polarization into classically (M1) and alternatively (M2) activated macrophages. M1 macrophages activate immune and inflammatory response, while M2 macrophages are involved in tissue remodeling. Mahonia oiwakensis (Mo) is a herbal medicine in Asia used for its anti-inflammatory and analgesic properties; however, the mechanism is unclear. This study analyzed the effect of Mo extracts and its effects on the polarization of both macrophage RAW264...

INTRODUCTION: Severe trauma is accompanied by endothelial glycocalyx disruption, which drives coagulopathy, increasing transfusion requirements and death. This syndrome has been termed traumatic endotheliopathy (EOT). Some have suggested EOT results from endothelial cellular damage and apoptosis. Endothelial microvesicles (EMVs) represent cellular damage. We hypothesized that EOT is associated with endothelial damage and apoptosis resulting in an increase in circulating EMVs. METHODS: Prospective, observational study enrolling severely injured patients...

Metastasis displays a highly heterogeneous cellular population with cancer cells continuously evolving. As a result, a single-ligand nanoparticle cannot account for the continuously changing expression of targetable biomarkers over time and space. To effectively direct nanoparticles to metastasis, we developed a multi-ligand nanoparticle by using four different types of ligands on the same nanoparticle that target biomarkers on the endothelium associated with metastatic disease. These vascular targets included αvβ3 integrin, P-selectin, EGFR and fibronectin...

Sepsis is characterized by an intense systemic inflammatory response activating a cascade of proinflammatory events resulting in leukocyte dysregulation and host tissue damage. The lung is particularly susceptible to systemic inflammation, leading to acute lung injury. Key to inflammation-induced lung damage is the excessive migration of neutrophils across the vascular endothelium. The mechanisms which regulate neutrophil activation and migration in sepsis are not well defined but there is growing evidence that platelets are actively involved and play a key role in microvascular permeability and neutrophil-mediated organ damage...

Triggering receptor expressed on myeloid cells (TREM)-1 on polymorphonuclear neutrophils (PMN) regulates innate immune activation in infectious and non-infectious conditions. TREM-1 ligation activates phosphatidyl-inositol 3 kinase (PI3K) triggering all neutrophil effector functions. As idelalisib is a PI3K inhibitor in clinical use for the treatment of non-Hodgkin lymphomas, we asked whether this inhibitor affects PMN functionalities. We analyzed PMNs from healthy donors or lymphoma patients for oxidative burst, phagocytosis, activation markers and IL-8 release upon TREM-1 or TLR ligation ex vivo...
