Mechanistic Insights Into Luminol Chemiexcitation: The Role of the Amide Carbonyls
By means of quantum‐chemical calculations, we demonstrate that the 1,2‐dioxin ring forms following nitrogen release from parent luminol. We also identify alkoxide groups derived from the amide carbonyls of luminol as key enhancers of the chemiexcitation yield.

Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Assembly and Maintenance of Myofibrils in the Heart
ABSTRACT The assembly of actin and myosin to the paracrystalline arrangement of myofibrils in striated muscle, that is, heart and skeletal, has puzzled many a cell biologist. Different models, based on cultured cardiomyocytes, were proposed for the last 30 years to explain the sequence of events.

Transcriptomic Profiling of SLC and ABC Transporters in the Human Term Placenta
Solute carriers (SLC) and ATP‐binding cassette (ABC) transporters are essential for placental solute exchange and fetal protection, yet their transcriptomic profiles in the human placenta remain poorly characterized. Although fetal sex influences placental development and function, its impact on transporter expression is unclear.
