: In this study, we assessed the oxidative damage occurring in plasma proteins when human blood was exposed to inflammatory concentrations of hypochlorous acid (HOCl). We used specific thiol labelling and Western blot analyses to determine protein thiol oxidation, as well as analytical gel filtration HPLC coupled to fluorescence detection to explore formation of high molecular weight (HMW) protein aggregates. Thiol-containing proteins oxidized by HOCl were identified by redox proteomics...

Nitric oxide (NO) produced by endothelial cells interacts with erythrocyte through band 3 protein, being scavenged by haemoglobin. A signal transduction mechanism involving protein Gi and protein band 3 stimulates erythrocyte NO efflux when acetylcholine (ACh) binds to erythrocyte membrane acetylcholinesterase. Binding of normal plasma fibrinogen (Fib) levels, to erythrocyte membrane CD47 decreases the NO efflux. When high Fib concentration and ACh were present the efflux of NO from erythrocytes was normalized...

Rheopheresis is an extracorporal selective double-filtration procedure. In the first part of the treatment the blood is passes through the plasma filter, which separates blood cells from the plasma. Then the plasma flow to a second filter called MONET (Membranefiltration Optimised Novel Extracorporal Treatment). The MONET filter retains high molecular weight proteins such LDL, Lp(a), fibrinogen, α2 macroglobulin, vWF and IgM. Hereby the whole blood and plasma viscosity decrease, improves microcirculation, and has a positive effect on lipid profile as well...

EMT-type zeolite nanoparticles (EMT NPs) with diameter smaller than 12 nm and uniform pore size of 7.3 Å have shown high selective affinity toward plasma protein (fibrinogen). Besides, the EMT NPs have demonstrated no adverse effect on blood coagulation hemostasis. Therefore, it was envisioned that the EMT NPs could inhibit possible β-Amyloid (Aβ)-fibrinogen interactions that result in the formation of structurally abnormal clots, which are resistant to lysis, in cerebral vessels of patients with Alzheimer disease (AD)...

[OBJECTIVE]: Elevated inflammation has been repeatedly observed in posttraumatic stress disorder (PTSD), and it may drive the development of both psychiatric symptoms and physical comorbidities. However, it is not clear if elevated inflammation is a feature of both remitted and current PTSD, and little is known about relationships between specific clusters of PTSD symptoms and inflammation. Exaggerated threat sensitivity, as indexed by threat reactivity and avoidance of perceived threats, may be particularly closely associated with inflammation...

: β2-Glycoprotein I (β2GpI) is the major autoantigen in the antiphospholipid syndrome, a thrombotic autoimmune disease. Nonetheless, the physiological role of β2GpI is still unclear. In a recent work, we have shown that β2GpI selectively inhibits the procoagulant functions of human a-thrombin (αT) (i.e. prolongs fibrin clotting time, tc, and inhibits αT-induced platelets aggregation) without affecting the unique anticoagulant activity of the protease, i.e. the proteolytic generation of the anticoagulant protein C (PC) from the PC zymogen, which interacts with αT exclusively at the protease catalytic site...

Acute myocardial infarction (MI) caused by ischemia is the most common cause of cardiac dysfunction. While growth factor therapy is promising, the retention in the highly vascularized myocardium is limited and prevents sustained activation needed for adequate cellular responses. Here, we demonstrated the use of polyethylene glycol-fibrinogen (PF) hydrogels for sustained dual delivery of vascular endothelial growth factor (VEGF) and angiopoietin-1 (ANG-1) to enhance myocardial repair and function. VEGF and ANG-1 were incorporated in PF hydrogels and their in vitro characteristics were studied...

Exogenous administration of coenzyme Q10 (CoQ10) has been shown in experimental models to have a protective effect against ischemia-reperfusion injury. However, it is unclear whether follow-up plasma CoQ10 concentration is prognostic of left ventricular (LV) performance after primary balloon angioplasty in patients with acute ST segment elevation myocardial infarction (STEMI).We prospectively recruited 55 patients with STEMI who were treated with primary coronary balloon angioplasty. Plasma CoQ10 concentrations were measured before primary angioplasty (baseline) and 3 days, 7 days, and 1 month after STEMI using high-performance liquid chromatography...

Fibrin fibers form the structural backbone of blood clots. The structural properties of fibrin clots are highly dependent on formation kinetics. Environmental factors such as protein concentration, pH, salt, and protein modification, to name a few, can affect fiber kinetics through altered fibrinopeptide release, monomer association, and/or lateral aggregation. The objective of our study was to determine the effect of thrombin and fibrinogen exposed to nitric oxide on fibrin clot properties. ProliNONOate (5 μmol/l) was added to fibrinogen and thrombin before clot initiation and immediately following the addition of thrombin to the fibrinogen solution...

The objective is to evaluate Grifols' DG-PT L Rec liquid reagent for prothrombin time (PT) determination in comparison to the laboratory's reference reagent (Siemens' Thromborel S). For linearity, the average master curve for PT and five nominal prothrombin concentrations was obtained from five calibration curves. Within-assay precision (repeatability) was calculated after measuring 20 successive tests of normal and pathological controls. For correlation, 581 routine clinical citrated plasma samples were assessed with both reagents...

Intracerebral hemorrhage (ICH) remains a cause of death in hematologic malignancies. Asparaginase represents a key agent in the treatment of acute lymphoblastic leukemia (ALL). The toxicity of asparaginase includes coagulopathy such as thrombotic or bleeding tendency. We report a case of fatal cerebral hemorrhage in a 12-year-old girl treated for ALL. Cerebral hemorrhage occurred after three injections of L-asparaginase. The patient presented with hypofibrinogenemia (0.36g/L), associated with thrombocytopenia (24,000/mm(3))...

Atherosclerosis is considered a chronic disease of the arterial wall and is the major cause of severe disease and death among individuals all over the world. Some recent studies have established the presence of bacteria in atherosclerotic plaque samples and suggested their possible contribution to the development of cardiovascular disease. The main objective of this preliminary pilot study was to better understand the bacterial diversity and abundance in human atherosclerotic plaques derived from common carotid arteries of individuals with atherosclerosis (Russian nationwide group) and contribute towards the further identification of a main group of atherosclerotic plaque bacteria by 454 pyrosequencing their 16S ribosomal RNA (16S rRNA) genes...

Nevertheless, a nonviable sperm population is present in the cauda epididymidis of many species. Degenerating spermatozoa release enzymes that could have detrimental effects on the viability of neighboring cells, and they are source of autoantigens that induce an autoimmune response if they escape the blood-epididymis barrier. Does the epididymis have specialized protective mechanism(s) to segregate the viable sperm population from defective spermatozoa? Previously, we identified a fibrinogen-like protein-2 (fgl2) that specifically binds to and polymerizes into a cocoon-like complex coating defective spermatozoa and sperm fragments...

Glioma is still difficult to treat because of its high malignancy, high recurrence rate, and high resistance to anticancer drugs. An alternative method for research of gliomagenesis and drug resistance is to use in vitro tumor model that closely mimics the in vivo tumor microenvironment. In this study, we established a 3D bioprinted glioma stem cell model, using modified porous gelatin/alginate/fibrinogen hydrogel that mimics the extracellular matrix. Glioma stem cells achieved a survival rate of 86.92%, and proliferated with high cellular activity immediately following bioprinting...
