Photosensitized Oxygenation of Lycopene

Bioscience, Biotechnology, and Biochemistry, 1994
Irradiation of lycopene in an atmosphere of oxygen and in the presence of a sensitizer (methylene blue) led to the formation of 2-methyl-2-hepten-6-one and apo-6’-lycopenal. A reaction pathway via a dioxetane intermediate is proposed.

University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.

Quality and stability of eggs from laying hens fed with organic minerals and lycopene

Ciência Rural, 2016
: This study aimed to evaluate the effect of using lycopene and organic minerals in diets for laying hens on the egg quality and stability of eggs stored for 30 days under different storage environments. An entirely randomized design was adopted in 2x3x3

Chemical Recycling as a Tool for Enabling a Second Life for Polyesters

SusMat, EarlyView.
This review presents the elucidation of the life cycle of main polyesters, detailing end‐of‐life methods, with focus of solvolysis technologies, then an analysis of LCA and TEA on literature data, an original data analytic, and, finally, a current industrial mapping of the main processes with a critical perspective on the plastic life‐cycle ecosystem ...

Management of Non‐Plaque‐Induced Gingival Conditions: A Systematic Review—Part 2: Inflammatory and Immune Conditions; Neoplasms; and Gingival Pigmentation

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aims This systematic review assesses current evidence on the management of non‐plaque (dental biofilm)‐induced gingival diseases and conditions (NPIGDs), including (i) inflammatory and immune conditions, (ii) neoplasms and (iii) gingival pigmentations.

Effects of lycopene on the initial state of atherosclerosis in New Zealand White (NZW) rabbits.

PLoS ONE, 2012
BackgroundLycopene is the main carotenoid in tomatoes, where it is found in high concentrations. Strong epidemiological evidence suggests that lycopene may provide protection against cardiovascular diseases.

Evaluation of Torula Yeast (Candida utilis) Single Cell Proteins as a Partial Replacement for Soybean Meal in Broiler Diets: Effects on Productive Performance, Meat Quality Traits, and Plasma Metabolome

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Over recent years the use of yeast in feedstuffs has gained momentum due to novel developments in single‐cell proteins (SCPs). SCPs are considered a sustainable protein source, as their production enable to convert low‐value substrates (including industrial/agricultural wastes) into feed, with a related reduced environmental impact.

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

Metabolic Engineering Escherichia coli for the Production of Lycopene

Molecules, 2020
Lycopene, a potent antioxidant, has been widely used in the fields of pharmaceuticals, nutraceuticals, and cosmetics. However, the production of lycopene extracted from natural sources is far from meeting the demand.

The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.
