Tetrabromobisphenol A – Toxicity, environmental and occupational exposures

open access: yesMedycyna Pracy, 2017
Brominated flame retardants (BFR), including tetrabromobisphenol A (TBBPA) represents 25% of the global market of flame retardants. Among them, TBBPA is used on the largest scale (approx. 60%) because of its firebreak properties and widespread occurrence

Characterization of a new hexaploid triticale 6D(6A) substitution line with increased grain weight and decreased spikelet number

open access: yesCrop Journal, 2019
Hexaploid triticale (×Triticosecale, AABBRR) is an important forage crop and a promising energy plant. Transferring D-genome chromosomes or segments from common wheat (Triticum aestivum) into hexaploid triticale is attractive in improving its ...

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

open access: yesSmall, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.

The Silent Link: Exploring the Impact of Periodontal Diseases on Head and Neck Carcinogenesis

open access: yesClinical and Experimental Dental Research, Volume 12, Issue 3, June 2026.
ABSTRACT Objectives Oral dysbiosis can accelerate the progression of head and neck squamous cell carcinoma (HNSCC) by fostering a pro‐inflammatory, immunosuppressive, and metabolically altered environment. This narrative review examines the relationships between periodontitis‐associated bacteria and HNSCC, focusing on their impact on oncogenic pathways,

Safe and Sustainable by Design (SSbD) Synthesis of Food and Personal Care Ingredients by Mechanochemistry

open access: yesChemSusChem, Volume 19, Issue 9, 14 May 2026.
A Safe and Sustainable by Design (SSbD) mechanochemical approach was used to prepare a marketed sweetener from a biomass derivative used in flavoring industry. A personal care ingredient was also synthesized. The study also evaluated and compared the reactivity in of polymeric jars with that in of common conventional stainless steel or and zirconium ...

Damnacanthal Suppresses Breast Cancer Cells by Inducing Apoptosis and Cell Cycle Arrest via NF‐ĸB Signaling

open access: yesPharmacology Research &Perspectives, Volume 14, Issue 2, April 2026.
ABSTRACT Breast cancer is the most common cancer diagnosed and the leading cause of death for women worldwide. Noni (Morinda citrifolia L.) contains an anthraquinone called damnacanthal (3‐hydroxy‐1‐methoxy‐anthraquinone‐2‐aldehyde), which is known to inhibit the growth of many types of cancer cells.

Sulfites Chemistry in Wines: From Reference Quantification Methods to More Sustainable Innovative Approaches

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 2, March 2026.
ABSTRACT Sulfites are widely used as preservatives in winemaking due to their antioxidant, anti‐enzymatic, and antimicrobial properties. However, dietary sulfites have been linked to adverse reactions in sensitive individuals, especially those with asthma.
