Introduction: In current and anticipated future conflicts, including large-scale combat operations, medical teams are tasked to provide prolonged casualty care (PCC) or extended patient care that occurs when delays in evacuation exceed the team's capabilities. Although the principles of PCC are often taught to military medical providers using simulation, educators rarely dedicate the time to training required to simulate the prolonged nature of these encounters. Therefore, a lack of knowledge exists regarding which aspects of extended care may be lost in an accelerated training scenario.

Theorists across all fields of psychology consider goals crucial for human action control. Still, the question of how precisely goals are represented in the cognitive system is rarely addressed. Here, we explore the idea that goals are represented as distributed patterns of activation that coexist within continuous mental spaces.

The cultivation and differentiation of human embryonic stem cells (hESCs) into organoids are crucial for advancing of new drug development and personalized cell therapies. Despite establishing of chemically defined hESC culture media over the past decade, these media's reliance on growth factors, which are costly and prone to degradation, poses a challenge for sustained and stable cell culture. Here, we introduce an hESC culture system(E6Bs) that facilitates the long-term, genetically stable expansion of hESCs, enabling cells to consistently sustain high levels of pluripotency markers, including NANOG, SOX2, TRA-1-60, and SSEA4, across extended periods.

Chordoma is a rare malignant tumor with a higher incidence in males than in females. There is an increasing number of clinical studies related to tyrosine kinase inhibitors (TKIs), yet the efficacy and safety of different drugs vary. In this single-arm meta-analysis evaluating the efficacy and safety of TKIs for chordoma treatment, 12 studies involving 365 patients were analyzed.
