Advanced Healthcare Materials, Volume 15, Issue 29, 7 August 2026.Pharmacokinetic engineering of clickable radioligands was achieved via albumin hitchhiking approach within a pretargeted radiotheranostics delivery platform. This approach reduced rapid renal elimination, expanded bioorthogonal capture window, boosted tumor uptake by ∼3.5‐fold, and improved the tumor‐to‐liver ratio by ∼6‐fold.

Biomedical Chromatography, Volume 40, Issue 8, August 2026.ABSTRACT Olaparib belongs to the PARP inhibitors and is widely used as an anticancer drug. Due to frequent side effects, it is usually co‐administered with an antihypertensive, such as propranolol and/or an antidiuretic, such as furosemide. In this study, a highly sensitive HPLC‐FLD method was developed for the simultaneous determination of the three ...

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 4, Page 429-444, August 2026.ABSTRACT Cadmium (Cd2+) contamination in agricultural soils has been reported to pose risks to crop productivity, food safety, and human health. This review synthesizes current knowledge on the mechanisms by which essential (S, Zn, Fe, Mg, K, Ca) and beneficial (Si, Se, rare earth elements) elements mitigate Cd2+ toxicity in plants.
