Coagulation Markers in Heparin Reversal

Check if the same lab product or an alternative is used in the 5 most similar protocols
Whole blood samples were taken into vacutainer tubes containing 3.2% trisodium citrate (Greiner Bio-One, Stonehouse, UK) and ethylenediaminetetraacetic acid (BD, Oxford, UK). Samples were taken before heparin administration and 30 min after reversal of heparin by protamine sulfate, PPP was prepared by centrifuging samples twice at 1650g before freezing in aliquots at −80°C for testing later. Full blood cell counts were performed on an ABX Pentra DX 120 automated analyser (Horiba Medical, Northampton, UK). The PT, APTT, Clauss fibrinogen and factors II, V, VII, VIII, IX, X, XI, antithrombin, protein C, free protein S and postoperative anti-Xa activity were measured on an ACL 500 Top (Instrumentation Laboratory, Cheshire, UK) automated coagulometer using standard manufacturer protocols and reagents. Factor XIII activity was measured in a flat-bottomed Immulon 2hb 96-well plate (Diagnostica-Stago, Asnières sur Seine, France) using a chromogenic assay kit from Technoclone (Vienna, Austria) and light absorbance was measured using a plate reader (BioTek, Winoosi, Vermont, USA).

Fasting venous blood samples were collected in the morning after 8 h of fasting. The assays were performed at the laboratory in Cagri Private Medical Center and Firat University’s Faculty of Medicine using a biochemical analyzer (ABX Pentra DX 120; HORIBA, Ltd.). Hemograms were determined with an autoanalyzer (Coulter® LH 780 hematology system; Beckman Coulter, Inc.). The blood samples were processed within 30 min after blood collection. Baseline NLR was measured by dividing absolute neutrophil count by absolute lymphocyte count.

Preparation and Viral Inactivation of Platelet Lysate

Check if the same lab product or an alternative is used in the 5 most similar protocols
GMP-compliant PL (Mesengen) was prepared and virally inactivated, as previously described [8 (link), 9 (link)]. Briefly, after obtaining informed consent, buffy coats from healthy volunteers were centrifuged and treated with InterSol solution (318 mg Na-citrate 2H2O, 305 mg Na 2-phosphate anhydro, 105 mg Na dihydrogen phosphate 2H2O, 442 mg Na-acetate 3H2O, 452 mg NaCl, 100 mL H2O, Fenwal Inc., Lake Zurich, Illinois) and subsequently with 20–30% human plasma. Potential pathogens were inactivated by using the Intercept Blood System for Platelets (Cerus Corporation, Concord, California, USA). PL was stored at −80°C for 24 hours before thawing at 37°C for 60 minutes. This procedure was repeated three times to enrich the pool of growth factors. Concentration and sterility of the preparation were determined by the haematology analyzer ABX Pentra DX 120 (Horiba ABX, Montpellier, France) and BACTEC 9240 (Becton and Dickinson), respectively. 5 U/mL heparin was added to cell culture media in order to avoid fibrin gel formation.

Demographic information, epidemiological history, clinical symptoms, comorbid diseases, imaging features, laboratory data, and length of stay were collected through an electronic medical record system. CBC data were determined using an ABX Pentra DX 120 (Horiba Medical, Montpellier, France) hematology analyzer. Biochemical tests were performed with Roche's Cobas 8000 c502 Analyzer (Roche diagnostics; Geneva, Switzerland). Coagulation tests were performed with the Sysmex CS-2500 System coagulation analyzer (Siemens Healthcare Diagnostics, Erlangen, Germany).

Comprehensive Immune Cell Profiling

The total number of WBCs, neutrophils, eosinophils, lymphocytes, and
monocytes were recorded by standard procedures using the ABX Pentra DX 120
(Horiba, United Kingdom/Germany). Furthermore, T-cell (CD3), T-helper cells
(CD4), T-cytotoxic cells (CD8), B-lymphocytes (CD19), NK (CD16/56) cells and
CD4+ recent thymic emigrants (CD4-RTE) absolute counts were performed by a
single-platform no-lyse-no-wash procedure. Fifty μl EDTA anti-coagulated
peripheral blood were incubated in TRUCount tubes (BD Biosciences, Denmark) with
a panel of conjugated monoclonal antibodies. The following combinations of
antibodies were used to characterize T cells as CD4 T cells (CD3-PerCP (clone
SK7), CD4-FITC (clone SK3), CD8 T cells (CD3-PerCP (clone SK7), CD8-PE (clone
SK1)) and CD4-RTE (recent thymic immigrant) cells as (CD3-ECD (clone UCHT1),
CD4-PC7 (clone SFCT12T4D11), CD31-PE (clone WM59), CD45RA-FITC (clone L48), and
CD45RO-PC5 (clone UCHL1), NK cells as (CD45-PerCP (clone 2D1), CD16/56-PE (clone
B73.1 + NCAM16.2), and CD3-FITC (clone SK7)), and B cells as (CD19-PE (clone
4G7), CD45-PerCP (clone 2D1)) (BD Biosciences, Beckman Coulter and AbD Serotec,
Denmark). The samples were measured on FC500 flow cytometer (Beckman Coulter,
Denmark). The laboratory participates in the quality assurance program by
National External Quality Assessment Site (NEQAS).

Differential count of leucocytes was performed using the equipment ABX Pentra DX 120 (Horiba Medical, Montpellier, France). Blood was collected from rats after 6 h instillation of vehicle or LPS. This equipment uses a Double Hydrodynamic Sequential System technology (Patent of Horiba ABX), which is a combination of Chlorazol black E cytochemistry, focused flow impedance, and light absorbance measurement for blood cell count and 5-part white blood cell differentials78 (link).

Hematological Parameters During Vertigo

MPV, PDW, platelet count, neutrophil count and lymphocyte count in blood samples were measured. Venous blood samples were obtained from antecubital vein at the time of vertigo attack and collected into tubes containing ethylenediaminetetraacetic acid (EDTA) at 9 am. following an overnight fast. To avoid platelet swelling measurements were done shorter than 30 minutes after sampling. An automated blood cell counter was used for these measurements (Horiba ABX Pentra DX 120).

Routine laboratory analyses included serum levels of total protein and albumin (colorimetry), determined with an automatic biochemical analyzer (Konelab 6.0, Winer, Argentina).
Hemoglobin levels were determined by photometry, using the ABX Pentra DX120 (Horiba Ltd, Kyoto, Japan). Serum calprotectin (S100A8/A9, MRP8/14) was measured by ELISA (Multiskan FC Microplate Photometer, Thermo Scientific Uniscience) using a commercially available kit (DRG Diagnostics, EIA5111; Springfield, New Jersey, USA). The standard curve ranged from 3.9 to 250 ng/mL. Plasma zinc and copper values were determined by flame atomic absorption spectrophotometry (Varian, model AA200, Melbourne, Australia), at a wavelength of 213.9nm and 327.4nm, respectively. The normal values for plasma zinc and copper were set at 70-140µg/dL and 50-120µg/dL, respectively.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
