In the United States, chest radiography and computed tomography (CT) are the most employed imaging techniques to assess pleural disease for diagnosis and management. However, repeated imaging using these modalities exposes patients to cumulative ionizing radiation. In contrast, chest ultrasonography offers a safer, cost-effective, and portable alternative that could be of advantage to pediatric, rural, or resource-limited hospital settings. In addition, ultrasonography brings great utility to preclinical research where advanced imaging is limited. In this study, we developed and validated an ultrasound-based tool that enabled pleural effusion and clot volume quantification in our preclinical models of disease (early-stage empyema, advanced-stage empyema, and retained hemothorax). Four methods were tested for estimating pleural effusion and of the two of these most accurate methods were used to quantify clot volume. Across three animal models of pleural disease, both the Predicted Pleural Effusion and Clot Volume (mL) were closest to the actual volume (gold standard, mL) when area volumetry (pleural effusion or clot) was conducted in the coronal view of the pleural space of the subjects. Lastly, ultrasonographic imaging was able to distinguish the difference in clot dissolution (Predicted Clot Volume, mL) between subjects treated with vehicle control or fibrinolytic therapy, providing evidence of its utility in our preclinical model. These findings support the potential applications of these volumetric tools for preclinical and potential clinical use.</p>","PeriodicalId":75599,"journal":{"name":"Biomedical sciences instrumentation","volume":"61 2","pages":"287-299"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13148432/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147847389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ten participants (5 males, 5 females, aged 21-34 years) were tested under three conditions: full vision, full occlusion, and central vision obstruction allowing only peripheral vision access. Results revealed significantly better balance performance in the peripheral vision condition during somatosensory perturbations (Condition 4), with equilibrium scores higher than in the full vision condition (p = 0.02). Similarly, visual preference (VIS) scores, indicating reliance on visual input, were significantly elevated under peripheral vision conditions (p = 0.03). These findings highlight peripheral vision's critical role in improving postural sway and maintaining balance when central vision is impaired, as seen in conditions such as age-related macular degeneration (AMD). While central vision is vital for daily tasks requiring focused attention, peripheral vision provides crucial environmental cues for balance and stability. This research underscores the need for targeted interventions and balance training programs to mitigate fall risks in individuals with central vision loss. Future studies will explore these effects in populations with visual impairments to enhance clinical relevance and applicability of central vision on balance.</p>","PeriodicalId":75599,"journal":{"name":"Biomedical sciences instrumentation","volume":"61 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12211638/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ten healthy participants (mean age 24.5 ± 4.38 years) underwent randomized perturbation conditions with and without non-skid socks and 10% body weight applied via weighted vests. Results from two-way ANOVA and mixed-effects models revealed no significant effects of socks, weight, or their interaction on latency (p > 0.05). However, amplitude analysis showed a significant interaction (p < 0.001), indicating that the combination of socks and weight increased postural instability. Specifically, conditions involving non-skid socks and weight resulted in higher amplitudes, suggesting greater deviations of the center of gravity and increased fall risk. Conversely, non-skid socks alone reduced amplitude, enhancing stability compared to barefoot conditions. These findings highlight the nuanced effects of non-skid socks and added weight on balance and stability. While socks alone may improve postural control, their combination with weight appears to elevate instability. Future research should include larger, diverse samples to confirm these findings and guide clinical practice regarding non-skid socks and weighted training protocols.</p>","PeriodicalId":75599,"journal":{"name":"Biomedical sciences instrumentation","volume":"61 1","pages":"16-22"},"PeriodicalIF":0.0,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12188694/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144499795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
