The continuing significance of chiral agrochemicals
Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Frontiers in Plant Science, 2016 Abscisic acid (ABA), a pivotal phytohormone that is synthesized in response to abiotic stresses and other environmental changes, induces various physiological responses. Heme, in its unbound form, has a positive signaling role in cell-cycle initiation in

Association of iron‐protoporphyrin‐IX (hemin) with myosins [PDF]
FEBS Letters, 1990 Addition of myosins isolated from guinea pig heart and rabbit skeletal muscle to hemin solutions resulted in the appearance of new absorption spectra indicating association of hemin and the myosins. Binding stoichiometry based on absorption changes was found to be two hemin sites per myosin molecule.

Peptide‐directed nanovehicles enabling tumor‐selective ROS amplification and antitumor immunity
VIEW, EarlyView.Cancer cells are vulnerable to oxidative stress, yet exploit immune tolerance to escape destruction. In contrast, their metabolic profile is markedly altered to support rapid proliferation, accompanied by elevated production of reactive oxygen species (ROS).

Methaemoglobinaemia: From pathophysiology to contemporary clinical management
British Journal of Haematology, EarlyView.Summary Methaemoglobin (MetHb) is an oxidised form of haemoglobin (Hb) unable to bind oxygen. Raised levels of MetHb reduce the blood's oxygen‐carrying capacity, causing potentially severe hypoxaemia and possible death. The condition arises from three main pathologies: mutations in globin genes causing Haemoglobin‐M, inherited deficiency of the enzyme ...

PLoS ONE, 2020 Malus halliana is an iron (Fe)-efficient apple rootstock growing in calcareous soil that shows obvious 'greenness' traits during Fe deficiency. Recent studies have shown that exogenous sugars can be involved in abiotic stress.

British Journal of Haematology, EarlyView.Gene therapy is revolutionizing treatment paradigms for haemoglobinopathies, establishing a translational framework for disorders that impact red blood cell development. In their paper, Joshi et al. describe the preclinical and early clinical landscape of gene therapies for non‐haemoglobinopathy erythroid disorders and highlight common thematic ...
