The envelope (env) protein of SARS-CoV-2, a pivotal component of the viral architecture, plays a multifaceted role in viral assembly, replication, pathogenesis, and ion channel activity. These features make it a significant target for understanding virus-host interactions and developing vaccines to combat COVID-19. Recent structural studies provide valuable insights into the conformational dynamics and membrane topology of the SARS-CoV-2 env protein, shedding light on its functional mechanisms.

This study aimed to compare the effects of supine and prone sleeping positions on cardiac output (CO), systolic pulmonary arterial pressure (SPAP), and superior vena cava (SVC) flow in healthy newborns.
Methods: In the first 24-72 h of life, 40 healthy term newborns born in the same hospital were included in this prospective, cross-sectional, observational study.

Objective: Attention deficit/hyperactivity disorder (ADHD), whose definition, diagnosis and treatment has been the subject of debate in the scientific community for a long time, is the most common neurobehavioral disorder in childhood. There are many studies on the pathophysiology of attention deficit. However, there is no study in the literature based on direct or indirect measurement of cerebral venous circulation in ADHD, and the effect of methylphenidate (MPH) treatment on cerebral venous circulation.

Objectives: The heart is one of the organs frequently affected by the multisystem inflammatory syndrome in children (MIS-C), associated with severe acute respiratory syndrome coronavirus 2 infection. Cardiac involvement in patients with MIS-C was evaluated with physical examination findings, biochemical test, and cardiological imaging tests. We reported the degree of cardiac involvement in patients with MIS-C.
