Pharmacokinetics of Topical Administration of Altrenogest in Mares and Implications for Human Health

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Altrenogest is a synthetic progestogen widely used in equine reproductive management. Adverse effects to altrenogest have been reported in people with cutaneous exposure reported as the highest exposure pathway. Despite these reports, there has been no quantitative research to determine the capacity for altrenogest to be absorbed through skin.

The abundance of pollen coat small signaling proteins shows limited convergence between independent selfing transitions in Arabidopsis and Capsella

New Phytologist, EarlyView.
Summary In plants, a key example of convergence is the repeated evolution of floral traits associated with the transition from outcrossing to self‐fertilization, often resulting in the ‘selfing syndrome’ (e.g. reduced flower size and loss of scent). However, potentially overlooked changes concern the pollen coat, which plays a role in different aspects

Plant Peptides on the Rise: From Historical Insight to Future Applications

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant peptides constitute a rapidly expanding class of signalling molecules essential to plant physiology, mediating key processes such as development, stress adaptation, and immune responses. This review traces the history of plant peptide research, from the seminal discovery of systemin to the recent identification of non‐canonical peptides (

Effect of blood meals and mating on biodemographic characteristics of Aedes albopictus

Physiological Entomology, EarlyView.
Lifespan did not differ between virgin and mated males and females. The number of blood meals (one and two) significantly reduced adult lifespan compared with those with no blood meal. The effect of the second blood meal doubled females' egg production and their reproductive output.
