Disturbances of the microcirculation and abnormal hemorheological properties are important factors that play an important role in disseminated intravascular coagulation (DIC) and result in organ dysfunction or failure. In the present study, we established an animal model of DIC using intravenous Dextran 500 in rats, and used exogenous normal lymph corresponding to 1/15 of whole blood volume for...
INTRODUCTION Preanalytical errors, along the process from the beginning of test requests to the admissions of the specimens to the laboratory, cause the rejection of samples. The aim of this study was to better explain the reasons of rejected samples, regarding to their rates in certain test groups in our laboratory. MATERIALS AND METHODS This preliminary study was designed on the rejected sa...
Behcet´s disease (BD) is accepted as a systemic vasculitis. Vasculitis is observed predominantly on the venous system. Vessel involvement is frequently seen in males. This study was planned retrospectively evaluate demographic features, clinical features, vessel involvements in BD. Furthermore, we aimed to prospectively compare consecutively chosen patients with and without thrombosis and heal...
This abstract presents a laboratory study of a coagulation/flocculation process on an urban snow melt mixture. Coagulation/flocculation is ubiquitous in water treatment, but has seen little use in the stormwater context. Using a jar-test procedure five different chemicals are evaluated as primary coagulants and their treatment performance on urban snow melt with respect to solids removal and me...
We calculated the collapse of a / r 2 density peaked, slowly rotating molecular cloud core by 2D numerical radiation hydrodynamical simulations. The dynamics of the dust grains is calculated applying a multicomponent uid model. Acceleration by the radiation eld, coupling to the gas component by dynamical friction, coagulation and shattering of the grains is included. Relative velocities between...
The possible existence of distinctive, vascular bed specific alterations of coagulation and fibrinolytic parameters associated with three different types of thrombosis was investigated in young women (n = 68, <45 years at onset of the event) following myocardial infarction (MI) (n = 22), lacunar cerebral infarction (LACI) (n = 16), idiopathic deep vein thrombosis (VT) (n = 14) and venous thromb...
BACKGROUND Propylthiouracil is the most common drug used to treat hyperthyroidism. However, this drug could cause a severe disease, antineutrophilic cytoplasmic antibody-associated vasculitis (AAV), which was usually misdiagnosed. METHODS We reported a 60-year-old woman of propylthiouracil-induced AAV manifested as blood coagulation disorders. The patient was admitted because of hyperthyroidi...
asymmetric membranes are widely used in many industrial membrane separation processes. the major advantage of membrane filtration over the conventional process is its ability to remove a wider spectrum of particles without using any chemicals. hollow fiber configuration offer many advantages over flat-sheet or tubular membranes. the spinning process of hollow fiber may look simple, yet it is te...
BACKGROUND Pneumatic tube systems (PTSs) for the transport of blood samples are regaining popularity in medical centers after earlier reports that their use could introduce preanalytical distortions such as hemolysis and changes in blood gases. METHODS We drew duplicate blood samples from 30 volunteers. One sample was hand transported, and the other sample was transported through a PTS togeth...
To determine prognostic factors of clinically relevant radiographic progression (CRRP) in patients with rheumatoid arthritis (RA) in clinical practice.We performed a multicenter prospective study in Japan of biological disease-modifying antirheumatic drug (bDMARD)-naive RA patients with moderate to high disease activity treated with conventional synthetic DMARDs (csDMARDs) at study entry. We lo...
