A qualitative analysis of the effects of the COVID-19 response on low-income residents in Cameron County, Texas: Lessons for future pandemic response.

The coronavirus disease 2019 (COVID-19) pandemic had dramatic impacts throughout the United States (US). In Cameron County, Texas, along the Texas-Mexico border, the impacts of the virus were felt more severely than in most places in the US. Residents of the county, which has high rates of poverty, many multigenerational households, high levels of underlying conditions, and an uninsured population of almost 30 percent, were not only poised to be affected by the virus but also by the response policies put in place to contain it.

Vaccine spillover effects in Africa: A cross-national study of vaccine spillover and confidence in Kenya, Nigeria, and South Africa.

Background: Vaccine hesitancy and a distrust of the COVID-19 vaccine is widespread in many African nations, stemming from historic medical abuses and low confidence in governments. While studies have examined drivers of vaccine hesitancy in Africa, little is known about vaccine spillover effects: how prior experiences with vaccines influence individuals' confidence in vaccines and future vaccination behaviors.

Methods: In a large online survey conducted across three African countries (Kenya, N = 1545; Nigeria, N = 1557; South Africa, N = 1588), we examined five measures of vaccine spillover: how experiences with the COVID-19 vaccination process influenced respondents' confidence in the safety, efficacy, and importance of all vaccines approved for use in their country, and the likelihood of vaccinating themselves or their children in the future.

Enzyme Activity Inhibition of α-Amylase Using Molecularly Imprinted Polymer (MIP) Hydrogel Microparticles.

Molecularly imprinted polymers (MIPs) are a class of synthetic recognition materials that offer a cost-effective and robust alternative to antibodies. While MIPs have found predominant use in biosensing and diagnostic applications, their potential for alternative uses, such as enzyme inhibition, remains unexplored. In this work, we synthesized a range of acrylamide-based hydrogel MIP microparticles (35 μm) specific for the recognition of α-amylase.

Impact of Collegiate Football Games on Emergency Response Intervals: A Case Study of College Station, Texas (USA).

Objectives: Little is known about how mass gatherings affect emergency response intervals. Previous research suggests that college football games increase ambulance transport intervals, but their impact on emergency response intervals is unexplored. This study examines how collegiate home football games in College Station, Texas (USA) affect emergency vehicle response intervals.

Thymic epithelial organoids mediate T-cell development.

Although the advent of organoids has opened unprecedented perspectives for basic and translational research, immune system-related organoids remain largely underdeveloped. Here, we established organoids from the thymus, the lymphoid organ responsible for T-cell development. We identified conditions enabling mouse thymic epithelial progenitor cell proliferation and development into organoids with diverse cell populations and transcriptional profiles resembling in vivo thymic epithelial cells (TECs) more closely than traditional TEC cultures.
