The potential risk associated with foodborne pathogens in a watershed: Escherichia coli O157:H7 in dairy cattle.

We carried out an investigation to determine the occurrence of Escherichia coli O157:H7 in dairy herds in the Delaware County watershed and to identify the factors that play a role in the likelihood of presence of this organism among animals on these farms. The pathogen poses risk of environmental degradation and health to the inhabitants. A total of 2162 fecal samples were collected per rectum from a representative sample of cattle on 27 dairy farms.

High-content analysis and Kinetic Image Cytometry identify toxicity and epigenetic effects of HIV antiretrovirals on human iPSC-neurons and primary neural precursor cells.

Introduction: Despite viral suppression due to combination antiretroviral therapy (cART), HIV-associated neurocognitive disorders (HAND) continue to affect half of people with HIV, suggesting that certain antiretrovirals (ARVs) may contribute to HAND.

Methods: We examined the effects of nucleoside/nucleotide reverse transcriptase inhibitors tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) and the integrase inhibitors dolutegravir (DTG) and elvitegravir (EVG) on viability, structure, and function of glutamatergic neurons (a subtype of CNS neuron involved in cognition) derived from human induced pluripotent stem cells (hiPSC-neurons), and primary human neural precursor cells (hNPCs), which are responsible for neurogenesis.

Results: Using automated digital microscopy and image analysis (high content analysis, HCA), we found that DTG, EVG, and TDF decreased hiPSC-neuron viability, neurites, and synapses after 7 days of treatment.

Interrogating inclusion with youths who use augmentative and alternative communication.

Even as the goal of social inclusion underpins health and social services for disabled youths, those with communication impairments continue to lead narrowly circumscribed lives. In this Canadian study, we combined visual methods and interviews with 13 Canadian youths who use augmentative and alternative communication (AAC) to understand how they make 'practical sense' of discourses of inclusion. Drawing on Bourdieu's theory of practice, we suggest: (i) participants' narratives reveal habitus - a socially constituted set of dispositions - that predispose them to accommodate the devalued social positions and constricted conditions of existence imposed on them; (ii) some forms of 'inclusion' perpetuate symbolic violence, as youths who use AAC internalise, as seemingly 'natural', dominant social norms and values that privilege 'normal' bodies; and (iii) although their practices primarily reproduced the status quo, youths in the study also worked at the margins to create locally produced forms of inclusion that attempted to transform the 'rules of the game'.

Geography Shapes the Population Genomics of Salmonella enterica Dublin.

Salmonella enterica serotype Dublin (S. Dublin) is a bovine-adapted serotype that can cause serious systemic infections in humans. Despite the increasing prevalence of human infections and the negative impact on agricultural processes, little is known about the population structure of the serotype.
