Oxidative stress-induced fibrinogen modifications in liver transplant recipients: unraveling a novel potential mechanism for cardiovascular risk.

Background: Cardiovascular events represent a major cause of non-graft-related death after liver transplant. Evidence suggest that chronic inflammation associated with a remarkable oxidative stress in the presence of endothelial dysfunction and procoagulant environment plays a major role in the promotion of thrombosis. However, the underlying molecular mechanisms are not completely understood.

Esophageal achalasia: A case report in an adolescent.

Esophageal achalasia is an uncommon disease in pediatrics. With an insidious clinical presentation, diagnosis is delayed. Here we describe a case of esophageal achalasia in a 16-year-old girl, with the typical delay in consultation and diagnosis.

Comparative safety performance of autonomous- and human drivers: A real-world case study of the Waymo Driver.

After several years of public road testing, the commercial deployment of fully autonomous vehicles-or Automated Driving Systems (ADS)-is poised to scale substantially following significant technological advancements and recent regulatory approvals. However, the fundamental question of whether an ADS is safer than its human counterparts remain largely unsolved due to several challenges in establishing an appropriate real-world safety comparison method. As scaling ensues, the lack of an established method can contribute to misinterpretations or uncertainties regarding ADS safety and impede the continuous and consistent assessment of ADS performance.

ATP-P2X7R pathway activation limits the Tfh cell compartment during pediatric RSV infection.

Background: Follicular helper T cells (Tfh) are pivotal in B cell responses. Activation of the purinergic receptor P2X7 on Tfh cells regulates their activity. We investigated the ATP-P2X7R axis in circulating Tfh (cTfh) cells during Respiratory Syncytial Virus (RSV) infection.
