Background: Urine is an attractive biospecimen for nutritional status and population health surveys. It is an excellent non-invasive alternative to blood for appropriate biomarkers in young children and is suitable for home-based collection, enabling representative collections across a population. However, the bulk of literature in this population is restricted to collection in primary care settings.

- Neonatal calf diarrhea frequently leads to dehydration and metabolic acidosis, impacting calf mortality, growth, and productivity, prompting interest in technological disease detection.
- The study explored the relationship between saliva conductivity and pH with clinical and biochemical indicators in calves, assessing the health of 141 dairy-bred calves from one week old until 25 days or until they developed diarrhea.
- Results indicated that while saliva pH decreased in calves with diarrhea, saliva conductivity showed no correlation with diarrhea or dehydration, highlighting the complexity of hydration status assessments in these animals.
Portable real-time polarimeter for partially and fully polarized light.
Rev Sci Instrum
December 2024
We present a portable polarimeter capable of real-time visualization of partial and fully polarized light over a broad band of wavelengths. Our system utilizes a Raspberry Pi computer with a low-cost data acquisition "HAT" and an integrated photodetection circuit. Wide bandwidth operation is achieved through digital calibration of an arbitrary retardance waveplate presented herein.

Despite this, PCC has not been fully adopted in RAC in Australia and internationally, and concerns about the quality of care persist. Over the past 2 decades, Montessori for dementia and ageing has been introduced in RAC to support and inform a cultural change towards PCC.

- * Shotgun metagenome sequencing revealed that the fish microbiomes and river water microbiomes are similar at higher taxonomic levels but differ significantly in alpha and beta diversity at the genus level.
- * The study concluded that the piranha's microbiome serves as a good representative of the river water microbiome, with variations in beta diversity linked to environmental changes and selective pressures.
