Development of an experimental model for liver abscess induction in Holstein steers using an acidotic diet challenge and bacterial inoculation.

Holstein steers (n = 40; initial BW = 84.9 ± 7.1 kg) were used to study the genesis of liver abscesses (LA) using an acidotic diet challenge with or without intraruminal bacterial inoculation.

Group Level Assessment (GLA) as a methodological tool to facilitate science education.

Group Level Assessment (GLA) is a qualitative, participatory research methodology that can be used within science education, specifically to meet the Science and Engineering Practices dimension of the K-12 Next Generation Science Standards. In contrast to traditional qualitative research methods, GLA is a concrete methodological tool intended for large groups. GLA follows a 7-step process in which diverse stakeholders work together to generate, analyze and prioritize ideas that lead to action planning.

Creating a Culture of Youth as Co-Researchers: The Kickoff of a Year-Long STEM Pipeline Program.

STEM pipeline programs often include research experiences for youth, but fewer focus on youth as shared decision-makers or leaders in research efforts. Youth participatory action research (YPAR) and community-based participatory research (CBPR) orientations suggest that the quality and relevance of research will benefit from youth partnership. Because youth do not traditionally have the opportunity to serve in this type of leadership capacity, STEM pipeline programs that wish to elevate the role of youth in research must create a new culture of co-creation that upends the traditional pedagogical models adolescents experience in high school.

Establishing Statistical Equivalence of Data from Different Sampling Approaches for Assessment of Bacterial Phenotypic Antimicrobial Resistance.

To assess phenotypic bacterial antimicrobial resistance (AMR) in different strata (e.g., host populations, environmental areas, manure, or sewage effluents) for epidemiological purposes, isolates of target bacteria can be obtained from a stratum using various sample types.

A jack-of-all-trades: 2-mercaptosuccinic acid.

2-Mercaptosuccinic acid (MS) is an important and versatile substance for diverse fields of applications of which the most significant are surveyed in this article. Biological, chemical, and physical properties of MS as well as the knowledge of its synthesis and microbial degradation are illustrated. In addition, exemplary structural analogs of the organic sulfur compound are commented.
