Social Determinants in COVID-19 Experiences of Children With Disabilities Receiving School-Based Services in Chicago: Mixed-Methods Study of Parent/Guardian Perspectives.

Objective: To identify the impact of social determinants on the experiences of children with disabilities and their families during the COVID-19 pandemic from the perspective of parents/guardians.

Methods: A mixed-methods study engaged parents/guardians of children with Individualized Education Programs (IEPs) in July to August 2021 at a developmental/behavioral pediatrics clinic in 1 urban academic medical center. All parents/guardians completed study-specific surveys on experiences and impact of COVID-19.

Multivariate relationships among nucleus and Golgi properties during fibrillar migration are robust to and unchanged by epithelial-to-mesenchymal transition.

Epithelial-to-mesenchymal transition (EMT) and maturation of a fibrillar tumor microenvironment play important roles in breast cancer progression. A better understanding of how these events promote cancer cell migration and invasion could help identify new strategies to curb metastasis. The nucleus and Golgi affect migration in a microenvironment-dependent manner.

Positive Quantitative Relationship between EMT and Contact-Initiated Sliding on Fiber-like Tracks.

Epithelial-mesenchymal transition (EMT) is a complex process by which cells acquire invasive properties that enable escape from the primary tumor. Complete EMT, however, is not required for metastasis: circulating tumor cells exhibit hybrid epithelial-mesenchymal states, and genetic perturbations promoting partial EMT induce metastasis in vivo. An open question is whether and to what extent intermediate stages of EMT promote invasiveness.
