The contents of the platelet releasate (PR) play significant roles in hemostasis, inflammation, and pathologic sequelae. Careful platelet isolation to ensure quiescence and subsequent activation is key to the successful generation of PR. Here, we describe steps to isolate and aggregate quiescent washed platelets from whole blood of a clinical patient cohort. We then detail the generation of PR from isolated human washed platelets under clinical conditions. This protocol allows the investigation of platelet cargoes released through various activation pathways.

Extracorporeal membrane oxygenation (ECMO) supports patients with severe refractory cardiac or respiratory failure but managing residual circuit blood after weaning lacks consensus. After decannulation, the oxygenator and circuit retain approximately 500-700 mL of blood, depending on tubing length, cannula size, and circuit configuration. Clinicians usually choose among direct reinfusion, cell-salvage processing, or disposal.

Background: Platelet abnormalities are well-recognized complications of type 2 diabetes mellitus (T2DM). High glucose (HG) increases platelet mitochondrial dysfunction, apoptosis and hyperreactivity in T2DM, which underlie the occurrence of thrombotic events. Sulforaphane (SFN) is a dietary isothiocyanate enriched in cruciferous vegetables and possesses multiple biological activities.

(rocket salad; arugula) is a well-known edible plant commonly used in salads and as a topping for pizza and pasta. In this study, one new cyclic thiocarbamate () and four new kaempferol glycosides (-), along with 15 known compounds (-), were isolated from leaves of using chromatographic methods. The structures of all compounds were elucidated based on their HR-ESI-MS, H and C NMR, and 2D NMR data.

Background: With global warming and an aging population, the risk of cerebrovascular disease caused by environmental heat exposure increases.
Objective: Given the critical role of platelet activation and thrombosis in ischemic stroke, this study aimed to investigate the effects and underlying biological mechanisms of heatwaves on platelet activation.
Methods: During the hot season (May to September) from 2018 to 2020, 1830 patients with acute ischemic stroke admitted to four stroke centers in Tianjin were enrolled.

Managing patients with suspected heparin-induced thrombocytopenia (HIT) poses significant clinical challenges. Limited evidence exists on how management decisions impact clinical outcomes, leading to treatment recommendations based on low-certainty evidence. This study aimed to evaluate the treatment strategies and clinical outcomes of patients with suspected heparin-induced thrombocytopenia (HIT) in a contemporary multicenter cohort.
