(1) Background: Clinical approaches have depicted interconnectivity between the Achilles tendon and the plantar fascia. This concept has been applied in rehabilitation, prevention, and in conservative management plans, yet potential anatomical and histological connection is not fully understood. (2) Objective: To explore the possible explanation that the calcaneus acts as a hypomochlion. (3) Methods: 2 databases (Pubmed and Livivo) were searched and studies, including those that examined the relationship of the calcaneus to the Achilles tendon and plantar fascia and its biomechanical role. The included studies highlighted either the anatomical, histological, or biomechanical aspect of the lower limb. (4) Results: Seventeen studies were included. Some studies depicted an anatomical connection that slowly declines with age. Others mention a histological similarity and continuity via the paratenon, while a few papers have brought forward mechanical reasoning. (5) Conclusion: The concept of the calcaneus acting as a fulcrum in the lower limb can partially be supported by anatomical, histological, and biomechanical concepts. Despite the plethora of research, a comprehensive understanding is yet to be investigated. Further research exploring the precise interaction is necessary.

The acquisition of the patients’ active force is the key process to realize the active rehabilitation function of lower limb rehabilitation robot. This paper analyzes the relationship of human-machine coupling force and patients’ active force, based on what put forward a proposal to acquire the active force .A sensor is designed to detect the human-machine coupling force and a stress analysis is carried on based on the actual usage of the sensor. The scheme of the stress foil arrangement and bridge circuit design are discussed in the paper. And a FEA is also carried out to analyze the strain situation of the elastomer.

Purpose This study aims to propose a framework based on the main theoretical and empirical contributions present in the literature and articulate the main paths for future studies in knowledge-intensive entrepreneurship (KIE). Design/methodology/approach Using the systematic review method from a survey of 85 articles, related to the KIE focal issue, originated from the Web of Science, it was possible to exhaustively analyze the studies and to divide the theme into key categories. Findings The present research has raised the relationship of five categories to KIE conceptualizations; the data suggest that although the literature indicates a distancing from KIE research, there are multidisciplinary themes and approaches interlinked in the studies. Originality/value The systematic approach in the main theoretical and empirical contributions in KIE enabled us to relate five categories (entrepreneurs, innovation, internationalization, location and triple alliance), and finally, to understand the gaps suggested by the researchers.

Antibodies to oxidized LDL (oxLDL) may be associated with improved outcomes in cardiovascular disease. However, analysis is restricted by heterogenous study design and endpoints. Our objective was to conduct a comprehensive systematic review assessing anti-oxLDL antibodies in relation to coronary artery disease (CAD). Through a systematic literature search, we identified all studies assessing the relationship of either, IgG or IgM ox-LDL/ copper-oxLDL/ malondialdehyde-LDL, with coronary atherosclerosis or cardiovascular events in populations with, and without, established CAD. Systematic review best practices were adhered to and study quality was assessed. An initial electronic database search identified 2059 records, which was subsequently followed by abstract and full-text review. Finally, we included 18 studies with over 1811 patients with CAD. The studies varied according to populations studied, conventional cardiovascular risk factors and interventional modalities used to assess CAD. IgM anti-oxLDL antibodies were found to indicate protection from more severe CAD and possibly cardiovascular events, whilst the relationship with IgG is more complex and difficult to elucidate, with studies reporting divergent results. In this systematic review, there is evidence that suggests a relationship between anti-oxLDL antibodies and CAD, especially for the IgM subclass. However, further studies, with well-characterized prospective cohorts, will be important to clarify these associations.
