Mapping of exogenous choline uptake and metabolism in rat glioblastoma using deuterium metabolic imaging (DMI)

Frontiers in Cellular Neuroscience, 2023
IntroductionThere is a lack of robust metabolic imaging techniques that can be routinely applied to characterize lesions in patients with brain tumors. Here we explore in an animal model of glioblastoma the feasibility to detect uptake and metabolism of ...

Polarized light ions and spectator nucleon tagging at EIC [PDF]

, 2014
An Electron-Ion Collider (EIC) with suitable forward detection capabilities would enable a unique experimental program of deep-inelastic scattering (DIS) from polarized light nuclei (deuterium 2H, helium 3He) with spectator nucleon tagging.

Cosmological Deuterium Production in Non-Standard Scenarios [PDF]

, 2002
It is widely believed that the cosmic baryon density may be obtained by inferring deuterium abundances in low-metallicity quasar absorption line systems. The implicit assumptions which enter this argument are critically assessed.

Deuterium burning in objects forming via the core accretion scenario - Brown dwarfs or planets?

, 2012
Aims. Our aim is to study deuterium burning in objects forming according to the core accretion scenario in the hot and cold start assumption and what minimum deuterium burning mass limit is found for these objects.

Photochemical enrichment of deuterium in Titan's atmosphere: new insights from Cassini-Huygens [PDF]

, 2008
Cassini-Huygens data are used to re-examine the potential sources of the D/H enhancement over solar, measured in methane, in Titan's atmosphere. Assuming that the system is closed with respect to carbon, the use of constraints from the Huygens probe for ...

D₂-Filled Hollow-Core Fiber Gas Raman Laser at 2.15 μm

Photonics, 2022
Fiber lasers around 2 µm band have attractive applications, such as coherent detecting, material processing, pump source for mid-IR lasers based on nonlinear frequency shift, etc. Fiber gas Raman lasers (FGRLs) based on the stimulated Raman scattering of

Evolution of dispersion in the cosmic deuterium abundance

, 2016
Deuterium is created during Big Bang Nucleosynthesis, and, in contrast to the other light stable nuclei, can only be destroyed thereafter by fusion in stellar interiors.

Validation of deuterium incorporation against sterol balance for measurement of human cholesterol biosynthesis

Journal of Lipid Research, 1998
To examine the validity of the deuterium (D) incorporation technique for measurement of human cholesterol synthesis rates, D uptake from D2O into cholesterol was compared to sterol balance in 13 subjects each under three controlled diet settings ...

Field desorption ion source development for neutron generators

, 2008
A new approach to deuterium ion sources for deuterium-tritium neutron generators is being developed. The source is based upon the field desorption of deuterium from the surfaces of metal tips. Field desorption studies of microfabricated field emitter tip
