A Mathematical Model of Stroma-Supported Allometric Tumor Growth.

Mounting empirical research suggests that the stroma, or interface between healthy and cancerous tissue, is a critical determinate of cancer invasion. At the same time, a cancer cell's location and potential to proliferate can influence its sensitivity to cancer treatments. In this paper, we use ordinary differential equations to develop spatially structured models for solid tumors wherein the growth of tumor components is coordinated.

Assessment of a Fruit and Vegetable Prescription Program in the Northern Manhattan Community.

Purpose: This study aimed to assess whether produce prescription redemption was associated with food insecurity (FI), sociodemographics, and nutrition-related health measures, and to identify factors affecting participation.

Design: Retrospective, cross-sectional study. Patients, equally divided between groups who redeemed and did not redeem prescriptions, completed a follow-up survey.

A model of the innate immune response to SARS-CoV-2 in the alveolar epithelium.

We present a differential equation model of the innate immune response to SARS-CoV-2 within the alveolar epithelium. Critical determinants of the viral dynamics and host response, including type I and type II alveolar epithelial cells, interferons, chemokines, toxins and innate immune cells, are included. We estimate model parameters, compute the within-host basic reproductive number, and study the impacts of therapies, prophylactics, and host/pathogen variability on the course of the infection.

The impact of maturation time distributions on the structure and growth of cellular populations.

Here we study how the structure and growth of a cellular population vary with the distribution of maturation times from each stage. We consider two cell cycle stages. The first represents early G1.
