Journal of Applied Toxicology, Volume 46, Issue 6, Page 1987-2002, June 2026.ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

Effect of molecular structure and hydrogen bonding on the fluorescence of hydroxy-substituted naphthalimides [PDF]
, 1999 Fluorescence properties of hydroxy-naphthalimides were studied in methylene chloride in the absence and the presence of hydrogen-bonding additives. The position of the HO-substituent only slightly affects the radiative rate, however, the triplet yield ...

ChemistryOpen, Volume 15, Issue 6, June 2026.Thiosemicarbazones (TSC) have demonstrated promise as new chemotherapeutic agents against melanoma in both in vitro and In vivo studies. TSC are powerful metal coordinating agents, coordinating transition metal ions such as zinc, copper and iron in multiple oxidation states. It is this metal coordination that imparts the anticancer activity.

Coloration Technology, Volume 142, Issue 3, Page 439-455, June 2026.Abstract Plants and their extracts have been used for dyeing fabrics, skin and hair for thousands of years and have been experiencing a revival in the last years due to increasing health risks arising from oxidative hair dye precursors. We developed a novel two‐step method to dye keratin fibres based on in situ formed silver nanoparticles including a ...
