Influence of exogenous nitroso-glutatyon on intensity of oxidizing processes in smooth muscles of colon and bronchial tubes in intact and atopic sensitised porpoises (guinea pigs) was studied. In sensitised porpoises, antioxidant protection has been initially reduced against the background of increased maintenance of products of oxidizing that reflects a picture of oxidizing damage and can be associated with an inflammatory process. In incubation with nitroso-glutatyon, a decrease in activities of syperoxiddismutase and catalase is marked and, in sensitised animals, this effect has been expressed to a lesser degree. Syperoxiddismutase and catalase are antioxidant for the enzymes participating in protection of cells from free-radical damage. A dose-dependence decrease in activity catalase and syperoxiddismutase is defined by a parity of the enzymes participating in disintegration of nitrosoglutatyon and the enzymes which have kept antioxidant activity.

Background: The present study investigated whether semantic processing of word and object primes can bias visual attention using top-down influences, even within an exogenous cueing framework. We hypothesized that real words and familiar objects would more effectively bias attentional engagement and target detection than pseudowords or pseudo-objects, as they can trigger prior knowledge to influence attention orienting and target detection.
Methods: To examine this, we conducted two web-based eye-tracking experiments that ensured participants maintained central fixation on the screen during remote data collection.

Seed hardness is an important quality characteristic of pomegranate fruit. The development of seed hardness relies on the deposition of lignin in the inner seed coat, but the underlying molecular mechanisms remain unclear. In this study, we identified a member of ABCG transporters, PgABCG9, which may function in seed hardening by negatively regulating lignin biosynthesis.

Ammonium toxicity, resulting from prolonged use of ammonium as the sole nitrogen source, can lead to physiological and morphological disorders, ultimately stunting plant growth. Enhancing ammonium assimilation efficiency has been extensively explored as a strategy to mitigate ammonium toxicity. However, the role of AspAT, a key enzyme in nitrogen assimilation, remains underexplored.

Auxin stimulates chloroplast division by upregulating the expression of genes involved in chloroplast division and influencing the positioning of chloroplast division rings. Chloroplasts divide by binary fission, forming a ring complex at the division site. Auxin, particularly indole acetic acid (IAA), significantly influences various aspects of plant growth.
