Synthesis, Electrochemistry, In Vitro Antiprotozoal Efficacy and Mechanistic Study of Novel ‘Ferrantoin’ and Related Derivatives

open access: yesApplied Organometallic Chemistry, Volume 40, Issue 7, July 2026.
1,2‐Disubstituted ferrocene analogues bearing hydantoin or rhodanine synthons were synthesised and assessed for antitrypanosomatid activity. An antileishmanial early lead, analogue 23, acting through ROS generation and hence oxidative stress, was uncovered.

Polonium-210 in cigarette tobacco

open access: yesInternational Journal of Low Radiation, 2006
Tobacco and tobacco smoke contain minute amounts of some natural radionuclides such as 210Pb and 210Po, which are carcinogens. Intake of these radionuclides results in an increase of radiation doses to lung cells and tissues. Samples of the most frequently smoked cigarette brands were collected from the local market of Riyadh City, Saudi Arabia ...

Persuasive channel choices: Evidence from manager–investor interactions

open access: yesReview of Financial Economics, Volume 44, Issue 3, July 2026.
Abstract Managers of public companies communicate with investors through channels such as conference calls and press releases. We develop a linear optimization model that predicts the optimal allocation of positive and negative information across channels, accounting for investors' limited processing capacity and channel‐specific cognitive costs.

Role‐Specific Performance Profiles of Professional Cyclists in a Grand Tour

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 6, June 2026.
ABSTRACT Professional cycling in Grand Tours involves varied stage types and rider roles, but intra‐stage workload dynamics remain underexplored. Observational study of 36 male professional cyclists in the 2020 Vuelta a España, categorized as climbers (n = 13), all‐rounders (n = 13), and flat specialists (n = 10).
