OBJECTIVES To evaluate the efficacy of 3 commercially available systems: the Harvest SmartPReP 2 BMAC, Biomet BioCUE, and Arteriocyte Magellan systems. We compared the number and concentration of progenitor cells achieved both before and after centrifugation and the percentage of progenitor cells salvaged after centrifugation. METHODS Forty patients, mean age 47 ± 18 years (range: 18-92 years...

Background : Triglyceride examination was carried out in three stages, namely pre-analytical, analytical, and post-analytical stages. The pre-analytical stage of specimen processing is one the factors that can affect triglyceride levels. However, field are often for test oftenis not accordance with applicable regulations. Method This research a pre-experimental design intact Group Comparison. s...

OBJECTIVE To quantify the platelet concentration in the blood of SHR rats, by means of different centrifugation protocols, and to evaluate what the most effective method for obtaining platelets is. METHODS We used 40 male rats of the isogenic SHR lineage. The animals were divided into three groups: control, using whole blood without centrifugation; single centrifugation, using whole blood sub...

OBJECTIVES We review the studies that have evaluated intermittent short-radius centrifugation as a potential countermeasure for cardiovascular, musculoskeletal, and sensorimotor deconditioning in simulated weightlessness. METHODS The findings from 18 experimental protocols that have used bed rest and dry immersion for comparing the protective effects of centrifugation versus standing upright ...

Abstract Objectives: Extracellular vesicles (EVs) are heterogeneous membrane in diameter of 30-5000 nm, that transport proteins, non-coding RNAs (miRNAs), lipids and metabolites. Major populations include exosomes, ectosomes apoptotic bodies. The purpose this study was to compare the distribution EVs obtained under different conditions differential centrifugation, including ultracentrifugation,...
