Platelets play a vital role in the formation of dangerous arterial thrombosis. Platelets are activated by adhesive proteins or soluble agonists through their specific receptors. The receptor-mediated signaling pathways lead to common signaling events, which result in shape changes and inside-out signaling, leading fibrinogen binding to glycoprotein IIb/IIIa complex (integrin αβ).

Article Synopsis
  • Selenium (Se) is crucial for body functions, and this study investigates the effects of garlic-based green-synthesized selenium nanoparticles (GBGS-SeNPs) on various aspects of freshwater prawn (Macrobrachium rosenbergii) growth and health.
  • A dose-dependent increase in Se accumulation was seen in prawns fed diets with GBGS-SeNPs, which also enhanced the absorption of other essential minerals and improved growth metrics, food conversion ratio (FCR), and survival rates compared to control groups.
  • The study found that GBGS-SeNPs increased activities of important digestive enzymes and beneficial nutrient content while maintaining safe levels of certain biochemical markers, suggesting their potential as a growth promoter in prawns.

The inhibition of platelet activation is considered a potential therapeutic strategy for the treatment of arterial thrombotic diseases; therefore, maintaining platelets in their inactive state has garnered much attention. In recent years, nanoparticles have emerged as important players in modern medicine, but potential interactions between them and platelets remain to be extensively investigated. Herein, we synthesized a new type of carbon dot (CDOT) nanoparticle and investigated its potential as a new antiplatelet agent.
