THE MEASUREMENT OF SOME THERMAL PROPERTIES OF DEUTERIUM OXIDE, AND THEIR INTERPRETATION

, 1935
Values for the heat capacities of solid deuterium oxide and the resulting liquid, from initial temperatures between 4 °C. and − 78.5 °C. to a final temperature of 25.0 °C, have been determined.

Bubble Formation Control: Fabrication of Centimeter‐Sized Tissue‐Like Constructs by Catalase‐Coated Oxygen‐Releasing Hydrogel

Advanced Materials, EarlyView.
Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.

Comparison of deuterium incorporation and mass isotopomer distribution analysis for measurement of human cholesterol biosynthesis

Journal of Lipid Research, 2000
To compare endogenous cholesterol biosynthesis measured by deuterium incorporation (DI) and mass isotopomer distribution analysis (MIDA), cholesterol fractional and absolute synthetic rates were measured simultaneously by both techniques under identical ...

Body composition in Nepalese children using isotope dilution: the production of ethnic-specific calibration equations and an exploration of methodological issues.

, 2015
Background. Body composition is important as a marker of both current and future health. Bioelectrical impedance (BIA) is a simple and accurate method for estimating body composition, but requires population-specific calibration equations. Objectives. (1)

Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

Advanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Optical imaging of metabolic dynamics in animals

Nature Communications, 2018
Non-destructive methods to image metabolism in situ in living tissues are limited. Here the authors combine deuterium oxide probing and stimulated Raman scattering microscopy to image lipid metabolic dynamics and protein synthesis in cells and in vivo in

Deuterium oxide dilution accurately predicts water intake in sheep and goats

Animal, 2010
The aim of this study was to test whether the deuterium oxide dilution technique accurately predicts water intake in sheep and goats. Two other issues were also studied: (i) a comparison of water intake in sheep and goats and (ii) an assessment of ...

Radioprotection of cultured cells by preincubation in medium containing deuterium oxide

, 1991
Pretreatment with deuterium oxide (D2O) has been shown to protect mice against lethal effects of X-rays. In contrast, X-irradiation of cultured mammalian cells in D2O-containing medium has previously been reported to result in increased cell killing ...

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

Advanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,

Effects of Deuterium Oxide on Cell Cycle and Vesicle Speed in RBL-2H3 Cells

, 2014
For the first time we show the effects of deuterium oxide on the cell cycle and vesicle transport in rat basophilic leukemia (RBL-2H3) cells. RBL-2H3 cultured with 15 moles/L deuterium oxide were observed to halt near the G2-M-phase of the cell cycle ...
