High altitude characterized by the low partial pressure of the oxygen is a life-threatening condition that contributes to the development of acute pulmonary edema and hypoxic lung injury. In this study, we aimed to investigate the contribution of some inflammatory and oxidative stress markers along with antioxidant system enzymes in the pathogenesis of HAPE (high-altitude pulmonary edema) formation. We incorporated the study on 42 male rats to unravel the role of mast cells (MCs) and TNF-α in the lung after the effect of acute hypobaric hypoxia.

Production of polymer material goods on-demand is a recurring science fiction element, but advances in chemistry and engineering have pushed it closer to reality. Experienced at a hobby scale by 3D printing enthusiasts and at an industrial level through rapid prototyping and modular manufacturing, the approach is on its way to further flexibility and high-performance material production. We review the advances in on-demand materials design as well as manufacturing, using examples in space exploration and sustainability, because these are cases where the value proposition for rapid changes in materials is strong.

Microneedles (MNs) are emerging as versatile tools for both therapeutic drug delivery and diagnostic monitoring. Unlike hypodermic needles, MNs achieve these applications with minimal or no pain and customizable designs, making them suitable for personalized medicine. Understanding the key design parameters and the challenges during contact with biofluids is crucial to optimizing their use across applications.

User trust is pivotal for the adoption of digital health systems interventions (DHI). In response, numerous trust-building guidelines have recently emerged targeting DHIs such as artificial intelligence. The common aim of these guidelines aimed at private sector actors and government policy makers is to build trustworthy DHI.

➢ Jehovah's Witnesses refuse allogeneic blood products based on religious beliefs that create clinical, ethical, and legal challenges in orthopaedic surgery, requiring detailed perioperative planning and specific graft selection.➢ Detailed perioperative planning is particularly important for procedures with high intraoperative blood loss.➢ Graft selection must align with Jehovah's Witnesses patients' religious beliefs, with options including autografts, allografts, and synthetic materials; this requires shared decision-making between the patient and surgeon.
