Bridging the Gap: Engaging Black Men in Lung Cancer Research Through Barbershop Collaboration.

Health disparities persist among Black men, notably in the context of lung cancer and stress-related health outcomes. This study explores these disparities through a community-based participatory research (CBPR) approach, citizen science, and social network theory, leveraging the expertise and trust of Black barbers as community leaders. The purpose is to understand the nuanced connections between stress and lung cancer in this demographic.

Mesoamerican urbanism revisited: Environmental change, adaptation, resilience, persistence, and collapse.

Urban adaptation to climate change is a global challenge requiring a broad response that can be informed by how urban societies in the past responded to environmental shocks. Yet, interdisciplinary efforts to leverage insights from the urban past have been stymied by disciplinary silos and entrenched misconceptions regarding the nature and diversity of premodern human settlements and institutions, especially in the case of prehispanic Mesoamerica. Long recognized as a distinct cultural region, prehispanic Mesoamerica was the setting for one of the world's original urbanization episodes despite the impediments to communication and resource extraction due to the lack of beasts of burden and wheeled transport, and the limited and relatively late use of metal implements.

Disruption of de novo purine biosynthesis in Pseudomonas fluorescens Pf0-1 leads to reduced biofilm formation and a reduction in cell size of surface-attached but not planktonic cells.

Pseudomonas fluorescens Pf0-1 is one of the model organisms for biofilm research. Our previous transposon mutagenesis study suggested a requirement for the de novo purine nucleotide biosynthesis pathway for biofilm formation by this organism. This study was performed to verify that observation and investigate the basis for the defects in biofilm formation shown by purine biosynthesis mutants.

Global invasive potential of 10 parasitic witchweeds and related Orobanchaceae.

The plant family Orobanchaceae includes many parasitic weeds that are also impressive invaders and aggressive crop pests with several specialized features (e.g. microscopic seeds, parasitic habits).

Preparation of ribosomes loaded with truncated nascent proteins to study ribosome binding to mammalian mitochondria.

Supporting a co-translational model of protein import into mitochondria, we have previously shown that ribosome-nascent chain complexes (RNCs) specifically bind to mitochondria. When producing RNCs using the rabbit reticulocyte lysate in vitro translation system, it was necessary to maximize ribosome loading with truncated nascent proteins because it had a direct impact on RNC binding. We describe here the optimal conditions for preparing RNCs.
