Simultaneous Determination of Nitrite and Nitrate in Milk Samples by Ion Chromatography Method and Estimation of Dietary Intake [PDF]

open access: yes, 2016
The presence of nitrate and nitrite in foods may be considered hazardous after ingestion in the gastrointestinal tract due to their reaction with naturally occurred secondary amines to form potentially carcinogenic nitrosamines.

Operando Magic Angle Spinning Solid‐State NMR Spectroscopy of Methanol Photoreforming Over Titania‐Coated Silica Monoliths

open access: yesChemistry – A European Journal, Volume 32, Issue 9, 2 March 2026.
Photoreforming of methanol is followed in real time by solid‐state Magic Angle Spinning NMR. The transparent sapphire sample holder is irradiated by four LEDs at 11.5 kHz MAS. Efficient light penetration into the sample volume is ensured by silica monoliths with a network of macropores, coated with TiO2, and enhancing light penetration by a factor of ...

Ammonium Dinitramide as a Prospective N–NO2 Synthon: Electrochemical Synthesis of Nitro-NNO-Azoxy Compounds from Nitrosoarenes

open access: yesMolecules
In this study, the electrochemical coupling of nitrosoarenes with ammonium dinitramide is discovered, leading to the facile construction of the nitro-NNO-azoxy group, which represents an important motif in the design of energetic materials.

Synergetic Relay Between Atomic Hydrogen and Chlorine Radicals Enables Efficient Nitrate‐to‐Nitrogen Gas Conversion

open access: yesAdvanced Science, Volume 13, Issue 13, 3 March 2026.
Using photoelectrochemical (PEC) deep denitrification technology, a novel synergistic reduction‐oxidation process enables efficient conversion of nitrate (NO3−) to nitrogen (N2), while suppressing key intermediate ammonium (NH4+) and toxic nitrite (NO2−) accumulation.

The Effect of Interferon Type I Adjuvant Therapy on the Lifespan and Complications of Glioma Patients Undergoing Chemotherapy: A Systematic Review and Meta‐Analysis

open access: yesCancer Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background The malignant glioma, as the most common and aggressive primary brain and spinal cord neoplasm, has shown limited responsiveness to available treatments, including tumor dissection, radiation, and chemotherapy. Thus, interferon type I, as a supplemental therapy, is added to the main therapies to overcome neoplasm resistance and ...

Exploring the Key Role of Nanotechnology on Intratumoral Microbiome Modulation for Cancer Immunotherapy

open access: yesMedComm – Biomaterials and Applications, Volume 5, Issue 1, March 2026.
The review provides a comprehensive analysis of microbiome‐mediated oncogenic mechanisms in various cancers, emphasizing the unique therapeutic strategies facilitated by nanotechnology. It aims to fill this gap by systematically reviewing nanotechnology‐driven strategies for microbiome elimination, with a focus on their ability to improve the cold TME ...

Recent perspectives on the relations between faecal mutagenicity, genotoxicity and diet

open access: yesFrontiers in Pharmacology, 2011
DNA damage is an essential component of the genesis of colonic cancer. Gut microbial products and food components are thought to be principally responsible for the damage that initiates disease progression. Modified Ames tests and Comet assays have been
