Medulloblastoma (MB) is a common primary brain cancer in children. The sonic hedgehog (SHH) pathway is indispensable for the normal development of the cerebellum, and MB is often caused by persistent SHH activation owing to mutations in pathway components. Patched1 () is the primary receptor for the SHH ligand and a negative regulator of the SHH signal transduction pathway.

Neutrophils activation plays a pivotal role in the pathogenesis of atherosclerotic plaque formation, progression and rupture. An association between the leukocyte count and the risk of developing myocardial infarction has been well known for many years; however, only recently did Mendelian randomization studies show that a high neutrophil count is a causal risk factor for atherosclerotic cardiovascular disease. On the other hand, experimental studies show that depletion of circulating neutrophils impairs plaque development.

Background: Dual antiplatelet therapy (DAPT) for 12 months is the standard of care after coronary stenting in patients with acute coronary syndrome (ACS). The aim of this individual patient-level meta-analysis was to summarise the evidence comparing DAPT de-escalation to ticagrelor monotherapy versus continuing DAPT for 12 months after coronary drug-eluting stent implantation.

Methods: A systematic review and individual patient data (IPD)-level meta-analysis of randomised trials with centrally adjudicated endpoints was performed to evaluate the comparative efficacy and safety of ticagrelor monotherapy (90 mg twice a day) after short-term DAPT (from 2 weeks to 3 months) versus 12-month DAPT in patients undergoing percutaneous coronary intervention with a coronary drug-eluting stent.

Fish oil, renowned for its high content of omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), has gained considerable attention for its potential health benefits. EPA and DHA exhibit anti-inflammatory effects by promoting the production of specialized pro-resolving mediators (SPMs), such as resolvins and protectins. Fish oil has been studied for its potential to reduce bronchial inflammation, a key feature of respiratory conditions like asthma and COPD.

Introduction: Over the years, the conceptual approach to pediatric rehabilitation has reevaluated the parent's role in the therapeutic process, considering parental involvement as a necessary condition for the effectiveness of the intervention. In the field of pediatric intervention, the therapeutic use of robots represents a growing clinical interest, but the feasibility and applicability of these robotic interventions, including those involving parents, remain unclear. This systematic review aims to investigate parental involvement in robot-mediated interventions (RMI) for children and adolescents in the current literature.

Article Synopsis
  • Advanced micro/nanoscale technologies have made two-dimensional materials, like black phosphorus (BP), useful in practical applications, particularly for investigating solid-liquid interactions.
  • Molecular dynamics simulations reveal that the flow behavior of dodecane (C) molecules differs significantly based on the orientation of BP nanochannels, with flows along the zigzag direction being much faster (9 times higher) than along the armchair direction.
  • The study attributes these differences in velocity to the molecular orientation of C near BP walls; flow along the zigzag direction aligns molecules parallel to the flow, reducing friction, while the armchair direction causes perpendicular alignment, increasing friction and slowing flow.

Respiratory viruses represent the most frequent cause of mortality, morbidity and high healthcare costs for emergency visits and hospitalization in the pediatric age. Respiratory viruses can circulate simultaneously and can potentially infect the same host, determining different types of interactions, the so-called viral interference. The role of viral interference has assumed great importance since December 2019, when the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) came on the scene.
