Structural studies were performed on a renal specimen removed from a patient with milk of calcium in a calyceal diverticulum. Infrared spectroscopy revealed that stones consisted of crystals of calcium oxalate. On scanning electron microscopy and X-ray microanalysis, the intact surface of the stones was composed of weddellite and the fractured face of the stones showed calcium phosphate. Subsequently, stagnation is considered to be an important factor in the formation of milk of calcium.

Zeta Potential Change and curing effects on Shield Muck solidified by Metal Ion Complex Catalysis.

Using potentiometric testing, we investigated the zeta potential of shield muck curing materials' particle surfaces, varying the concentration of metal ion complex. We analyzed the microscopic characteristics of shield muck curing products by using the electron microscopy, revealing the impact of metal ion complex on curing. Results showed that the metal ion complex significantly reduces the surface zeta potential of shield muck and conventional curing materials, with cement showing the most substantial effect, followed by shield muck, calcium carbonate, and calcium sulfate.

Experimental objectives were to create a chronic inflammatory model to evaluate the effects of persistent immune activation on metabolism, inflammation, and productivity in lactating dairy cows. Twelve lactating Holstein cows (631 ± 16 kg BW; 124 ± 15 DIM) were enrolled in a study with 2 experimental periods (P); during P1 (5 d), cows were fed ad libitum and baseline data were obtained. At the initiation of P2 (7 d), cows were assigned to 1 of 2 treatments: 1) saline-infused and pair-fed (PF; 5 mL intravenously (IV) sterile saline on d 1, 3, and 5; n = 6) or 2) lipopolysaccharide infused and ad libitum-fed (LPS; 0.

Transient amorphous phases are known as functional precursors in the formation of crystalline materials, both in vivo and in vitro. A common route to regulate amorphous calcium carbonate (ACC) crystallization is via direct interactions with negatively charged macromolecules. However, a less explored phenomenon that can influence such systems is the electrostatically driven formation of Ca-macromolecule dense phases.

As teeth develop, their mineralised composition is a bio-recorder of diet, environment, and growth. High-resolution elemental mapping provides a tool to reveal records of life history within teeth. The relative concentrations of a range of trace elements change between in utero development, birth, and weaning in eutherian mammals.

The quantification of glyphosate (Gly) and its metabolite aminomethylphosphonic acid (AMPA) in food is often impaired by matrix components. Specifically, interaction between the analytes and natural matrix components in food leads to reduced analyte recovery rates. Here, we studied how the addition of ethylenediaminetetraacetic acid (EDTA) impacted the QuPPe recovery rates of Gly and its metabolite in eight mostly problematic matrices using tandem mass spectrometry.
