The presented study aims to determine T activation polyagglutination in critically ill COVID-19 patients.

Sickle Cell Disease and Thromboembolism: New Insights on the Pathophysiology, Diagnosis, and Treatment.

Sickle cell disease (SCD) is a genetic hemoglobinopathy caused by the abnormal hemoglobin S (HbS) in red blood cells. As a result of its deoxygenation and polymerization, the properties and formation of red blood cells become altered, which ultimately leads to the development of SCD. Chronic inflammatory processes produced by hemolytic and vaso-occlusive episodes, define SCD clearly.

Elevated Levels of Procoagulant Microvesicles and Tissue-Factor Bearing Microvesicles in Malaria Patients.

Background: Procoagulant microvesicles (MVs) are submicron membrane fragments released from activated cells and cells undergoing apoptosis. The procoagulant activity of MVs is enhanced in the presence of tissue factor (TF). MVs and TF are active mediators that induce pro-inflammatory response and prothrombotic tendency and have been linked to the severity of several disorders, including malaria infection.

Mitochondria: Emerging Consequential in Sickle Cell Disease.

Advanced mitochondrial multi-omics indicate a multi-facet involvement of mitochondria in the physiology of the cell, changing the perception of mitochondria from being just the energy-generating organelles to organelles that highly influence cell structure, function, signaling, and cell fate. This sets mitochondrial dysfunction in the centerstage of numerous acquired and genetic diseases. Sickle cell disease is also being increasingly associated with mitochondrial anomalies and the pathophysiology of sickle cell disease finds mitochondria at crucial intersections in the pathological cascade.

BPA and acetaminophen are widely used synthetic chemicals worldwide and both are known and have numerous toxic effects.

Procoagulant Microvesicles in COVID-19 Patients: Possible Modulators of Inflammation and Prothrombotic Tendency.

Background: The hypercoagulability and thrombotic tendency in coronavirus disease 2019 (COVID-19) is multifactorial, driven mainly by inflammation, and endothelial dysfunction.
