Syllectometry
WebSyllectometry is a measuring method that is commonly used to assess red blood cell (RBC) aggregability. In syllectometry, light is incident on a layer of whole blood initially exposed to shear flow. The backscattered light is measured after abruptly stopping the driving mechanism. The resultant time-dependent intensity plot is called the syllectogram. … WebMay 8, 2024 · National Center for Biotechnology Information

WebThe syllectometry. principle for measuring the RBC . Background/aim: Ankaferd hemostat (ABS; Ankaferd blood stopper, İstanbul, Turkey) is a prohemostatic agent affecting erythrocytes. The hemostatic action of ABS depends upon fibrinogen gamma chain, prothrombin, and red blood cells. WebNoun [ edit] syllectometry ( uncountable ) The measurement of erythrocyte aggregability when blood is subjected to shear.
WebNov 21, 2024 · Syllectometry is a measuring method that is commonly used to determine the red blood cell aggregability, which can be related to consequent sedimentation rate. As reference, in syllectometry light is incident to a layer … Webdetermined at 37uC via syllectometry (i.e., laser backscatter versus time). The RBC disaggregation threshold (c), i.e., the minimal shear rate needed to prevent RBC aggregation or to breakdown existing RBC aggregates, was determined using a re-iteration procedure. Measurements were made at 37uC. Erythrocyte deformability was characterized with ...
WebThe well known flow dependence of the optical density of whole blood was studied by measuring light transmission of blood in viscometric flow. A cone-plate chamber (3° cone angle) was transilluminated (λ=500–800 nm) while under shear (0–460 sec−1). The transmitted light was monitored with a selenium barrier layer photocell and was … WebDictionary entries.

WebMechanism []. Erythrocyte aggregation is a physiological phenomenon that takes places in normal blood under low-flow conditions or at stasis. The presence or increased concentrations of acute phase proteins, particularly fibrinogen, results in enhanced erythrocyte aggregation.. Current experimental and theoretical evidence supports the …
