The structure of a novel major carotenoid glycoside (nearly 80% of total carotenoids) from a newly isolated bacterium, Paracoccus schoinia NBRC 100637T, was determined to be adonixanthin diglucoside using spectral data. By contrast, carotenoid diglycosides are rare and are usually minor carotenoids in nature. The minor carotenoids in this bacterium included astaxanthin diglucoside, zeaxanthin diglucoside, canthaxanthin, echinenone, zeaxanthin, beta-cryptoxanthin, and beta-carotene.

Diet quality, psychological factors and their associations with risk factors of cardiovascular disease: a cross-sectional pilot study.
BMJ Nutr Prev Health
December 2024
Region Kalmar County Hospital, Kalmar, Sweden.
Background: Several modifiable risk factors, including dietary habits, are linked to cardiovascular disease (CVD) progression. However, lifestyle changes remain notoriously challenging, perhaps due to psychosocial factors. This pilot study aims to investigate the relationship between adherence to a healthy diet, CVD risk factors, psychological factors and sociodemographic variables among middle-aged adults in Sweden.

Objectives: To identify what changes in the prescribing of isotretinoin have occurred since funded prescriber access was widened in 2009 from 'dermatologist only' prescribing to include 'general practitioners (GPs) and nurse practitioners working within their scope of practice'.
Design: Evaluation of isotretinoin dispensing data from 2008 to 2023 using the national annual prescribing data obtained from the New Zealand Pharmaceutical National Collection database.
Setting: All New Zealand citizens prescribed and dispensed funded isotretinoin for acne from 2008 to 2023 were included.

Post-harvest losses and rapid fruit ripening at room temperature are major challenges in preserving fruit quality. This study aimed to reduce such losses by applying a red carotenoid pigment, bacterioruberin extracted from an sp. The carotenoid was characterized as bacterioruberin and its derivative tetra anhydrous bacterioruberin (λmax 490 nm), and an / value of 675 and 742 (M+ 1H).

The femtosecond dynamics of energy transfer from light-excited spirilloxanthin (Spx) to bacteriochlorophyll (BChl) a in the reaction centers (RCs) of purple photosynthetic bacteria Rhodospirillum rubrum was studied. According to crio-electron microscopy data, Spx is located near accessory BChl a in the B-branch of cofactors. Spx was excited by 25 fs laser pulses at 490 nm, and difference absorption spectra were recorded in the range 500-700 nm.

All-trans retinoic acid (ATRA) signaling is a major pathway regulating numerous differentiation, proliferation, and patterning processes throughout life. ATRA biosynthesis depends on the nutritional availability of vitamin A and other retinoids and carotenoids, while it is sensitive to dietary and environmental toxicants. This nutritional and environmental influence requires a robustness response that constantly fine-tunes the ATRA metabolism to maintain a context-specific, physiological range of signaling levels.
