Injury of the popliteal artery by shrapnel of a Ukrainian girl treated at the University Hospital Ostrava - case report of arterial lesion without acute limb ischemia.

A popliteal artery injury in a 12-year-old female patient, injured in the war conflict in Ukraine, proved to be serious, requiring surgical treatment, despite seemingly poor symptoms and the absence of subjective difficulties. The presentation of arterial injury without acute limb ischemia was atypical. The clinical picture of the lower limb in the sense of "pulseless pink" based on an arterial lesion is not common, but its underestimation can have permanent consequences for the patient.

Coordinative Self-assembly of π-Electron Magnetic Porphyrins.

π-Electron magnetic compounds on surfaces have emerged as a powerful platform to interrogate spin interactions at the atomic scale, with great potential in spintronics and quantum technologies. A key challenge is organizing these compounds over large length scales, while elucidating their resulting magnetic properties. Herein, we offer a relevant contribution toward this objective, which consists of using on-surface synthesis coupled with coordination chemistry to promote the self-assembly of π-electron magnetic porphyrin species.

Perceptions of Illness Control, Coherence, and Self-Efficacy Following a Web-Based Lifestyle Program for Multiple Sclerosis: A Qualitative Analysis of Semistructured Interviews.

Background: Evidence suggests that illness perceptions held by people living with multiple sclerosis (MS) impact affective distress and physical health outcomes. In a randomized controlled trial, we developed 2 MS Online Courses-the standard care course and the intervention course (IC). The IC was adapted from an evidence-based lifestyle program.

Atomically resolved imaging of the conformations and adsorption geometries of individual β-cyclodextrins with non-contact AFM.

Glycans, consisting of covalently linked sugar units, are a major class of biopolymers essential to all known living organisms. To better understand their biological functions and further applications in fields from biomedicine to materials science, detailed knowledge of their structure is essential. However, due to the extraordinary complexity and conformational flexibility of glycans, state-of-the-art glycan analysis methods often fail to provide structural information with atomic precision.
