Effects of colchicine on platelet aggregation in patients

Apr 25,  · Platelets aggregation leading to thrombosis plays a pivotal role in the pathophysiology of acute coronary syndrome (ACS) and of stent thrombosis. Antiplatelet therapy with aspirin plus an ADP-receptor inhibitor (ticagrerol, prasugrel or clopidogrel) is recommended to reduce the risk of other platelet-mediated events. Clopidogrel is recommended in patients with Chronic Coronary Syndromes

Platelet Aggregation - ClinLab

Platelet aggregation and ATP secretion are clinically significant in the detection and diagnosis of acquired or congenital qualitative platelet defects. The platelet’s ability or inability to respond to particular aggregating reagents is the basis for differentiating platelet dysfunctions as shown in the table below.

Coffee is rich in caffeine (CF), chlorogenic acid (CGA) and phenolics. Differing types of coffee beverages and brewing procedures may result in differences in total phenolic contents (TPC) and biological activities. Inflammation and increases of platelet activation and aggregation can lead to thrombosis. We focused on determining the chemical composition, antioxidant activity and inhibitory

Antiplatelet aggregation and antithrombotic benefits of

Particularly, compounds 10 and 24 inhibited ADP-induced platelet aggregation and delayed FeCl 3-induced thrombus in zebrafish. Furthermore, interactions between compounds 10 and 24 with two ADP receptors P2Y 1 and P2Y 12 , serving as the target for key regulators of antiplatelet aggregative activity, were investigated via molecular modeling.

Oct 28, · Antiplatelet drug is a generic term, descri agents which decrease platelet aggregation and inhibit thrombus formation. Antiplatelet drugs are most effective for arterial clots that are composed largely of platelets. Platelets are critical in haemostasis and the development of arterial thrombi.

Jun 13, · In addition to its antiplatelet actions, garlic also lowers cholesterol and blood pressure, which are all important to cardiovascular health, notes the University of Pittsburgh Medical Center. A study published in 1991 found that garlic reduced platelet aggregation, or “stickiness,” in humans, the University of Michigan notes.

What is the Difference Between Anticoagulant and Antiplatelet

Jul 12, · Other names for antiplatelet drugs include antiaggregant, platelet agglutination inhibitor or platelet aggregation inhibitor. The main characteristic feature which discriminates between anticoagulant and antiplatelet drugs is that antiplatelets inhibit thrombus formation by preventing the aggregation of platelets.

New Copper Compounds with Antiplatelet Aggregation Activity

Tests for antiplatelet aggregation activities of all of the four compounds were conducted. Results: X-ray diffraction studies show that (L1) and (L2) exist in the enol-imine tautomeric form with a strong intramolecular hydrogen bond. NMR studies show that both ligands are found as enol-imine tautomers in CDCl3 solution.

Conformation of the dihydropyrano ring of cis-3',4'-disenecioylkhellactone was elucidated by X-ray crystallographic analysis. These three natural khellactone esters were subjected to the antiplatelet aggregation bioassay where cis-3',4'-diisovalerylkhellactone showed significant activity (at 50 micrograms/ml).
