The goal of the University of Wisconsin-Milwaukee WInSTEP SEPA program is to provide valuable and relevant research experiences to students and instructors in diverse secondary educational settings. Introducing an online experience allows the expansion of a proven instructional research program to a national scale and removes many common barriers. These can include lack of access to zebrafish embryos, laboratory equipment, and modern classroom facilities, which often deny disadvantaged and underrepresented students from urban and rural school districts valuable inquiry-based learning opportunities. An online repository of zebrafish embryo imagery was developed in the Carvan laboratory to assess the effects of environmental chemicals. The WInSTEP SEPA program expanded its use as an accessible online tool, complementing the existing classroom experience of our zebrafish module. This virtual laboratory environment contains images of zebrafish embryos grown in the presence of environmental toxicants (ethanol, caffeine, and nicotine), allowing students to collect data on 19 anatomical endpoints and generate significant amounts of data related to developmental toxicology and environmental health. This virtual laboratory offers students and instructors the choice of data sets that differ in the independent variables of chemical concentration and duration of postfertilization exposure. This enables students considerable flexibility in establishing their own experimental design to match the curriculum needs of each instructor.

Background: Vonoprazan and amoxicillin (VA) dual therapy as a mainstream Helicobacter pylori regimen has gained momentum worldwide, but the optimum dosages remain unclear. We aimed to compare the efficacy and safety of VA dual therapy with 2 g amoxicillin or 3 g amoxicillin, and to assess the short-term effects of therapy on the gut microbiota and antibiotic resistome.
Methods: We conducted an open-label, non-inferiority randomised controlled trial at 12 centres in China.

As a highly emitted volatile organic compound, toluene significantly contributes to atmospheric pollution and poses high risks to human health. Its anthropogenic source is well understood, while its biosynthesis remains poorly understood, especially by bacterial communities. This research attempted to reveal the temporal changes of bacterial community structure during toluene biosynthesis and identify key bacterial factors using 16S rRNA sequencing gene and machine learning methods.

Background & Aims: Malnutrition is highly prevalent in those with cancer and more so in those with incurable cancer. In incurable cancer, it is widely agreed that optimal nutritional care has the potential to positively impact patient and caregiver distress and oncological outcomes. The aim of this systematic review was to describe the diversity and frequency of nutritional interventions, whether given in isolation or as part of a multimodal intervention in those with incurable cancer, in randomised controlled trials.

Background: Current donor risk assessments to identify risk of infectious transmission through transplantation have been criticized as unnecessarily discriminatory for sexual and gender minorities. Little is known about how increased infectious risk donor (IIRD) patients transition through the deceased donation system. We sought to evaluate how IIRD status and other equity-relevant identities impacted the likelihood of a caregiver of a deceased donor being approached for organ donation and the likelihood of caregiver consent.

Maintaining and enhancing agricultural productivity for food security while preserving the ecology and environment from the harmful effects of toxicants is the main challenge in modern monoculture farming systems. Microbial biological agents can be a promising substitute for traditional synthetic pesticides to manage plant diseases. Trichoderma spp.
