The Role of Blood-Brain Barrier Transporters in Pathophysiology and Pharmacotherapy of Stroke.
Abstract Cerebral ischemia is one of the major causes of disability worldwide. In cerebral ischemic stroke, occlusion of a major cerebral artery by an embolus or local thrombosis can result in transient or permanent reduction of cerebral blood flow to a portion of the brain, resulting in deprivation of glucose and oxygen. Since the brain relies on a continuous supply of nutrients and ions via mostly carrier mediated processes across the blood-brain barrier (BBB), any irregularity in these transport mechanisms dramatically affects neuronal function and outcome after acute and chronic stroke. Despite numerous encour...

Canagliflozin Inhibits Human Endothelial Cell Proliferation and Tube Formation
In conclusion, the present study identified canagliflozin as a potent inhibitor of human EC proliferation. The anti-proliferative action of canagliflozin is observed in ECs isolated from both the venous and arterial circulation, and is partly due to the blockade of cyclin A expression. In addition, this study found that canagliflozin inhibits tube formation in cultured ECs and mouse aortic rings. Notably, these actions are specific for canagliflozin and not seen with other SGLT2 inhibitors. The ability of canagliflozin to exert these pleiotropic effects on EC function may contribute to both the adverse and salutary actions...

Evaluation of Prescribing Practices and Outcomes Using Direct-Acting Oral Anticoagulants After Cardiac Surgery
Clin Ther. 2021 May 30:S0149-2918(21)00203-4. doi: 10.1016/j.clinthera.2021.04.009. Online ahead of print.ABSTRACTPURPOSE: Cardiac surgery patients frequently require anticoagulation. Warfarin remains the preferred agent, and a few trials have reported negative outcomes with the use of direct-acting oral anticoagulants (DOACs) in these patients. Therefore, limited literature exists that supports the dosing, safety, and efficacy of DOACs within the cardiac surgery population.METHODS: This single-center, retrospective analysis was conducted at a tertiary academic medical center. All data were extrapolated from electronic med...

Targeting Platelet G Protein‐Coupled Receptors for Antithrombotic Therapy
Abstract Platelets are small anucleated cells produced by bone marrow megakaryocytes that circulate in the blood as sentinels of vascular integrity. They play a pivotal role in the regulation of vascular homeostasis through adhesion to the injured vessel wall, aggregation, propagation of coagulation, and thrombus formation. Furthermore, platelets are also involved in fibrinolysis and the repair of the blood vessel wall, restoring blood flow and vascular integrity. Under pathophysiological conditions such as atherosclerosis, inappropriate platelet aggregation and clot formation can cause vascular occlusions, resultin...

Current knowledge on assessing the effects of and managing bleeding and urgent procedures with direct oral anticoagulants.
CONCLUSION: With or without reversal agents, patients may require supportive management such as mechanical pressure, volume support, transfusions of blood products, and, depending on the situation, surgery to repair the bleeding source. Specific reversal agents are currently under development or have recently been approved for the urgent management of bleeding events or the facilitation of invasive procedures in patients receiving DOACs.

Crosstalk between Platelet and Bacteria: A Therapeutic Prospect.
Abstract Platelets are typically recognized for their roles in the maintenance of hemostasis and vascular wall repair to reduce blood loss. Beyond hemostasis, platelet also plays a critical role in pathophysiological conditions like atherosclerosis, stroke, thrombosis, and infections. During infection, platelets interact directly and indirectly with bacteria through a wide range of cellular and molecular mechanisms. Platelet surface receptors such as GPIbα, FcγRIIA, GPIIbIIIa, and TLRs, etc. facilitate direct interaction with bacterial cells. Besides, the indirect interaction between platelet and bacteria involv...
