Flavin-dependent azoreductases have been applied to a wide range of tasks from decolorizing numerous azo dyes to releasing azo-conjugated prodrugs. A general narrative reiterated in much of the literature suggests that this enzyme promotes sequential reduction of both the azo-containing substrate and its corresponding hydrazo product to release the aryl amine components while consuming two equivalents of NAD(P)H. Indeed, such aryl amines can be formed by incubation of certain azo compounds with azoreductases, but the nature of the substrates capable of this apparent azo bond lysis remained unknown.

Cell cycle involves the sequential and reiterative progression of important events leading to cell division. Progression through a specific phase of the cell cycle is under the control of various factors. Since the cell cycle in multicellular eukaryotes responds to multiple extracellular mitogenic cues, its study in higher forms of life becomes all the more important.

Purpose: This study analyzed the sequences of actions in professional men and women padel players to identify common game patterns.
Methods: The sample comprised 17,557 stroke-by-stroke actions (N = 1640 rallies) of the championship World Padel Tour. Multistep Markov chains were used to calculate the conditional probabilities of occurrence of actions during the rally.

Stem cell division contributes to the generation of various cell types during animal development, especially a diverse pool of neural cells in the nervous system. One example is reiterated unequal stem cell divisions, in which a large stem cell undergoes a series of oriented unequal divisions to produce a chain of small daughter cells that differentiate. We show that reiterated unequal stem cell divisions are involved in the formation of the brain in simple chordate appendicularians (larvaceans).

Transfection describes the delivery of exogenous nucleic acids (NAs) to cells utilizing non-viral means. In the last few decades, scientists have been doing their utmost to design ever more effective transfection reagents. These are eventually mixed with NAs to give rise to gene delivery complexes, which must undergo characterization, testing, and further refinement through the sequential reiteration of these steps.
