Probing Ligand-Induced Conformational Changes in an MFS Transporter in vivo Using Site-Directed PEGylation.

So far, site-directed alkylation (SDA) studies on transporters in the Major Facilitator Superfamily (MFS) are mostly performed at conditions different from the native cellular environment. In this study, using GFP-based site-directed PEGylation, ligand-induced conformational changes in the lactose permease of Escherichia coli (LacY), were examined in vivo for the first time. Accessibility/reactivity of single-Cys replacements in a Cys-less LacY-eGFP fusion background was tested using methoxy polyethylene glycol-maleimide-5K (mPEG-Mal-5K) in the absence or presence of a ligand, and the band-shift of the fusion upon PEGylation was detected by in-gel fluorescence.

The use and usefulness of the Peninsula Health Falls Risk Assessment Tool (PHFRAT) process in residential aged care: a mixed methods study across 25 aged care facilities.

Background: Falls remain a persistent problem in residential aged care (RAC) facilities. Fall screening and assessment tools such as the Peninsula Health Falls Risk Assessment Tool (PHFRAT) are widely used to inform falls risk and guide fall prevention interventions. However, it is unclear how it is used in practice and whether clinicians believe it supports resident care.

A Shift in Approach to Addressing Public Health Inequities and the Effect of Societal Structural and Systemic Drivers on Social Determinants of Health.

Social determinants of health (SDOH) are the conditions in which people are born, grow, live, work, and age that influence health outcomes, and structural and systemic drivers of health (SSD) are the social, cultural, political, and economic contexts that create and shape SDOH. With the integration of constructs from previous examples, we propose an SSD model that broadens the contextual effect of these driving forces or factors rooted in the Centers for Disease Control and Prevention's SDOH framework. Our SSD model (1) presents systems and structures as multidimensional, (2) considers 10 dimensions as discrete and intersectional, and (3) acknowledges health-related effects over time at different life stages and across generations.

Protocol for CRISPR-Cas9 genome editing of a swine cell line via electroporation.

Genome editing technology is being used in animals for a variety of purposes, including improvement of animal and public health outcomes. Characterization of genome editing reagents and anticipated genomic alterations is an essential step toward the development of an edited animal. Here, we present a protocol for genome editing in the swine testicular (ST) cell line.
