Study Title | Estimating Platelet Mitochondrial Function in Patients with Sepsis - Platelet NMRs (part-I) |
Study Type | single timepoint |
Study Summary | Relationships between platelet mitochondrial oxygen consumption rates (mOCR) and metabolites in platelets as measured by quantitative 1H-NMR metabolomics. Samples collected in ED at a single timepoint. WB and platelets isolated from the same blood samples. Comparison of mitochondrial function and metabolomics in patients with sepsis and non-sepsis ED patients |

Project Title: | Estimating Platelet Mitochondrial Function in Patients with Sepsis |
Project Type: | Quantitative NMR Metabolomics |
Project Summary: | Sepsis patients and ill controls admitted to the ED had matched whole blood (WB) and isolated platelet samples collected. The control group was chosen to represent an acutely ill 127cohort of the same racial, sex, and age as the sepsis cohort. NMR was run on extracted WB and platelets to determine how the metabolome reflects mitochondrial function |

Collection:
Collection ID: | CO001363 |
Collection Summary: | WB samples (12 mL each) were collected by direct venipuncture or from an indwelling line into K2 EDTA-containing tubes. Platelets were then isolated. centrifuged (200x gfor 6 min at room temperature).The platelet-rich plasma layer was transferred to another tube and centrifuged (4500x gfor 5 minat 4C) to pellet the platelets.The nearly cell-free plasma layer was transferred to a new tube, leaving approximately 0.25 mL of plasma in the original tube. Remaining plasma was used to resuspend the platelet pellet to produce ultra-rich plasma. |
