Sex-specific ultrasound imaging biomarkers of neurodegeneration in a mouse model.

Introduction: Early detection of neurodegeneration is essential for optimizing interventions. The highly reproducible progression of neurodegeneration in the decrepit () mouse allows investigation of early biomarkers and mechanisms of brain injury.

Methods: Using high-frequency ultrasound, the common carotid arteries of female and male and control mice were imaged longitudinally at time points bracketing the disease progression (50, 75, and 125 days of age) ( = 6 mice/group/sex).

The Relationship between Diet Costs and Dietary Adequacy: A Scoping Review of Measures and Methods with a Focus on Cost Estimation using Food Supply Data.

Background: "Diet cost" refers to a methodological approach developed by Drewnowski et al. to estimate individual daily diet costs, where cost vectors are derived by matching prices from food supply data to the food sources of reported intakes from dietary assessment tools. The dietary assessment method and food price collection approach have been found to vary diet cost estimates.

Quality of Life and Body Dissatisfaction in Cisgender Men Reporting Sexual Attraction Toward Men or Women.

Gay men report poorer body image than straight men, but no research has examined other dimensions of sexual identity (e.g., sexual attraction).

Development of the 10-question household foodwork interactional assessment questionnaire (FIA-Q10).

Background: Public health nutrition recommendations and clinical dietary interventions emphasize eating healthy food at home, implicitly requiring household foodwork. Household foodwork is defined as the physical and mental tasks a household does for eating meals and snacks. Because no tools exist to measure it, how much time people spend doing household foodwork and the foodwork barriers they experience remain unknown.

VMXm - A sub-micron focus macromolecular crystallography beamline at Diamond Light Source.

VMXm joins the suite of operational macromolecular crystallography beamlines at Diamond Light Source. It has been designed to optimize rotation data collections from protein crystals less than 10 µm and down to below 1 µm in size. The beamline has a fully focused beam of 0.
