The mammary microenvironment has been shown to suppress tumor progression by redirecting cancer cells to adopt a normal mammary epithelial progenitor fate in vivo. However, the mechanism(s) by which this alteration occurs has yet to be defined. Here, we test the hypothesis that mitochondrial transfer from normal mammary epithelial cells to breast cancer cells plays a role in this redirection process. We evaluate mitochondrial transfer in 2D and 3D organoids using our unique 3D bioprinting system to produce chimeric organoids containing normal and cancer cells. We demonstrate that breast cancer tumoroid growth is hindered following interaction with mammary epithelial cells …

INTRODUCTION: Healthcare resources are often crucial but limited, requiring careful consideration and informed allocation based on population needs and potential healthcare access. In resource allocation settings, availability and accessibility of resources should be examined simultaneously. The two-step floating catchment area (2SFCA) method has been previously used to evaluate spatial accessibility to healthcare resources and services, and to address health-related disparities. The 2SFCA methods have regained significant popularity during the COVID-19 pandemic, as their application proved crucial in addressing priority public health data analysis, modeling, and accessibility challenges. However, comprehensive comparisons of the 2SFCA method input parameters in the context of …

Revisiting Circular Economy Rebound: Market Dynamics, Policy Implications, And Future Research Directions, Trevor Zink Ph.D., Benjamin H. Lowe, Andrea Genovese, David Font Vivaco
Management Faculty Works
The circular economy has gained momentum as a sustainability paradigm that aims to decouple economic growth from environmental degradation by promoting resource efficiency and waste minimization. However, mounting evidence points to a critical challenge: circular economy rebound (CER). This phenomenon occurs when efficiency improvements intended to reduce resource use provoke systemic, market, or behavioral responses that diminish or even reverse the anticipated environmental gains. This is particularly problematic within growth-oriented economies, where resource efficiency often reinforces rather than reduces consumption. This paper draws on insights from a roundtable discussion with leading experts—Trevor Zink, David Font Vivanco, and Andrea Genovese—to critically …

Introduction: Secondhand tobacco smoke (SHS) exposure remains a major public health concern for children and has been implicated in sleep disturbances through biological and behavioral mechanisms. Different methods of measuring SHS exposure have yielded inconsistent results. This study examined the relationship between SHS exposure and sleep among rural Appalachian 7–9-year-olds, utilizing three SHS measurements: natural log-transformed (ln) serum cotinine concentrations, dichotomized serum cotinine levels (≥0.05 vs. <0.05 ng/ml), and parent/caregiver report of ≥1 smoker in the home. We hypothesized SHS-exposed children would have a significantly higher prevalence of sleep disturbance—e.g., short sleep, frequent snoring, night awakenings—compared to unexposed, regardless of measurement method. Methods: We used data from the Marietta Community Actively Researching Exposure Study, a cohort of 404 children in Marietta and Cambridge, Ohio. Sleep disturbances were parent/caregiver-reported. Linear models were used for continuous outcomes to estimate beta coefficients; log-binomial models with generalized estimating equations (exchangeable correlation) were applied for dichotomized outcomes to estimate prevalence ratios (PR), each with 95% confidence intervals (CI). Results: Twenty-six percent of children had a parent/caregiver report of ≥1 sleep disturbance. There was a 35% increased prevalence of short sleep [PR = 1.35 (95%CI:1.02–1.80), p =.04] with each unit increase of ln serum cotinine levels, adjusting for age, sex, parent education, BMI percentile, and history of breathing difficulties in the past two years. Increasing ln serum cotinine levels were associated with a significant 5.5-min decrease in average sleep duration in age-adjusted models. Conclusions: Higher SHS exposure was associated with poorer sleep outcomes, with serum cotinine emerging as the only measure linked to short sleep, underscoring the importance of smoke-free environments, particularly in rural communities, and objective exposure assessment.

The present study experimentally investigates the performance of a vapor compression refrigeration cycle (VCRC) integrated with a heat pipe functioning as a heat exchanger. The heat pipe was developed to enhance heat transfer between the suction and liquid lines of the VCRC. The integration of the heat pipe heat exchanger (HPHE) aims to decrease the compressor duty cycle, which consequently enhances system longevity and reduces energy consumption. The effects of different working fluids and filling ratios in the HPHE on the system performance were examined. Specifically, the impact of these parameters on the refrigeration effect (RE), and overall coefficient of …

Trends in advanced sciences and technology
Plant-parasitic nematodes (PPNs) are among the most significant agents contributing to plant disease complexes, acting both as direct parasites and as facilitators of bacterial infections. Their interactions with phytopathogenic bacteria are multifaceted, involving mechanical wounding caused by stylet penetration, disruption of plant cell integrity, and alteration of host physiology. These changes create favourable conditions for bacterial entry, colonization, and systemic spread. Additionally, PPNs can suppress plant defines responses and modify root exudate profiles, thereby enhancing bacterial survival and virulence in the rhizosphere. Such interactions often lead to a synergistic increase in disease incidence and severity, resulting in greater yield losses …
