Nanostructured surfaces have the potential to influence the assembly as well as the orientation of adsorbed proteins and may, thus, strongly influence the biomaterials performance. For the class of polymeric (bio)materials a reproducible and well characterized nanostructure is the ordered chain folded surface of a polyethylene single crystal (PE-SC). We tested the hypothesis that the trinodal-rod shaped protein human plasma fibrinogen (HPF) adsorbs on the (001) surface of PE-SCs along specific crystallographic directions...

Fibrinogen and its functional aspects have been linked to cardiovascular disease. There is vast discrepancy between the heritability of fibrinogen concentrations observed in twin studies and the heritability uncovered by genome wide association studies. We postulate that some of the missing heritability might be explained by the pleiotropic and polygenic co-regulation of fibrinogen through multiple targeted genes, apart from the fibrinogen genes themselves. To this end we investigated single nucleotide polymorphisms (SNPs) in genes coding for phenotypes associated with total and γ' fibrinogen concentrations and clot properties...

A sulfated polysaccharide, designated as SLEP-1, was obtained after sulfation of the exopolysaccharide (LEP-1) which was isolated from Lachnum. The degree of substitution (DS) of sulfate group of SLEP-1 was 1.97. SEM images of SLEP-1 revealed laminated structure in mesh. UV, FT-IR and (13)C NMR spectra indicated that the LEP-1 was sulfated successfully. The result of the anticoagulant activity in vitro showed that both of LEP-1 and SLEP-1 could effectively prolong activated partial thromboplastin time (APTT) and thrombin time (TT) of the normal mice plasma, in which SLEP-1 was more effectively than those of LEP-1, and dose-effect relationships were found...

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...

Multiple functions of platelets in various physiological and pathological conditions have prompted considerable attention on understanding how platelets are generated and activated. Of the adaptor proteins that are expressed in megakaryocytes and platelets, Disabled-2 (Dab2) has been demonstrated in the past decades as a key regulator of platelet signaling. Dab2 has two alternative splicing isoforms p82 and p59. However, the mode of Dab2's action remains to be clearly defined. In this review, we highlight the current understanding of Dab2 expression and function in megakaryocytic differentiation, platelet activation and integrin signaling...

OBJECTIVES: Postoperative bleeding in cardiac surgery remains an important complication, leading to increased morbidity and mortality. Different interventions are possible to prevent/treat postoperative bleeding. The present study aims to investigate the effectiveness of these interventions in a real-world scenario. METHODS: This is a retrospective study based on 19 670 consecutive adult cardiac surgery patients operated from 2000 to 2015. During the study period, the following interventions have been applied and tested for effectiveness with a before versus after analysis: thromboelastography (TEG)-based diagnosis and treatment in actively bleeding patients; platelet function tests (PFTs); timing of surgery based on PFTs; fresh frozen plasma (FFP)-free strategy using prothrombin complex concentrate and fibrinogen concentrate...

The control of bleeding is one of the most important interventions after a traumatic injury. Hemostatic devices delivering blood clotting accelerating agents such as fibrinogen are increasingly used due to their efficacy and their ease of application. In the present study, we describe a method to incorporate the coagulant supplements fibrinogen and thrombin in silk protein sponges by mixing the coagulants with an aqueous silk solution, followed by molding, freeze-drying and water annealing. In this combination system we demonstrate the delivery of fibrinogen while maintaining its hemostatic potential...

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...

BACKGROUND: The Quantra Hemostasis Analyzer is a novel diagnostic device that uses an ultrasound-based technology, sonic estimation of elasticity via resonance (SEER) sonorheometry, to characterize the dynamic changes in viscoelastic properties of a blood sample during coagulation. Cardiac surgery utilizing cardiopulmonary bypass (CPB) is associated with a significant impact on the coagulation system and can result in perioperative coagulopathy. The aim of this study was to correlate SEER sonorheometry results to corresponding rotational thromboelastometry (ROTEM) and laboratory parameters obtained before, during, and after CPB...

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...

Neuroinflammation plays an important role in the recovery of brain injury in ICH. Macrophage is the major executor in the neuroinflammation and initiates neurological defects. Programmed death 1 (PD-1) delivers inhibitory signals that regulate the balance between T cell activation, tolerance, and immunopathology. PD-1 expression by macrophages plays a pathologic role in the innate inflammatory response. However, the exact role of PD-1 on inflammatory responses following ICH has not been well identified. In this experiment, PD-1 KO (PD-1 -/-) ICH mice and Wild-type (WT) ICH mice were caused by intracranial injection of type IV collagenase...
