Heterocyclic amines detected in cooked meats and fishes from street markets and restaurants in the city of Hanoi, Vietnam: A Pilot local field investigation findings in 2020

Toxicology Reports, 2022
Background: Street food has been a typical culinary feature of many countries. These foods, mainly, meats and fish, were often fried, and grilled with varied marinade and preparation.

Mechanisms linking colorectal cancer to the consumption of (processed) red meat : a review [PDF]

, 2015
Colorectal cancer (CRC) is the third most commonly diagnosed cancer in the world. The vast majority of CRC cases have been linked to environmental causes rather than to heritable genetic changes.

Hyperpolarization of Molecular Deuterium

Angewandte Chemie, EarlyView.
Hyperpolarized molecular deuterium is generated and detected using a nonhydrogenative SABRE catalyst with nicotinamide. The resonance shows a strongly enhanced partially negative line, substrate‐dependent and sensitive to transient intermediates.

Intermolecular Nuclear Spin Hyperpolarization Transfer via Cross‐Relaxation Triggers RASER of Solute Molecules

Angewandte Chemie, EarlyView.
Radiofrequency amplification by stimulated emission of radiation (RASER) of solutes was achieved via parahydrogen‐induced polarization (PHIP) and polarization transfer from the produced hyperpolarization donors to solutes via the intermolecular nuclear Overhauser effect (NOE).

Unsaturated cryptophanes: Toward dual PHIP/hyperpolarised xenon sensors [PDF]

Magnetic Resonance in Chemistry, 2017
Cryptophanes, cage‐molecules constituted of aromatic bowls, are now well recognised as powerful xenon hosts in 129Xe NMR‐based biosensing. In the quest of a dual probe that can be addressed only by NMR, we have studied three cryptophanes bearing a tether with an unsaturated bond.

Parahydrogen-induced polarization enables the single-scan NMR detection of a 236 kDa biopolymer at nanomolar concentrations

Scientific Reports, 2023
Nuclear magnetic resonance (NMR) experiments utilizing parahydrogen-induced polarization (PHIP) were performed to elucidate the PHIP activity of the synthetic 236 kDa biopolymer poly-γ-(4-propargyloxy)-benzyl-L-glutamate) (PPOBLG).

Transfer of Parahydrogen Induced Polarization in Scalar Coupled Systems at Variable Magnetic Field [PDF]

, 2012
Para-Hydrogen Induced Polarization (PHIP) experiments were performed in coupled multispin systems at variable magnetic fields. We studied the magnetic field dependence of PHIP in styrene, which is the product of hydrogenation of phenylacetylene.
