The Effect of the Combination of Two Postbiotics on Anxiety-like Behavior in Animal Models.

With increasing evidence showing the connections between the microbiome, neurophysiology, and behavior, our research endeavors to investigate whether the consumption of a combination of two postbiotics with antioxidant effects can affect behavior regulation in model species. Here, we worked with a combination (1:1 ratio) of heat-treated subsp. ES1 (CECT7347) and BPL15 (CECT8361) as a dietary supplement.

Impact of different levels of handling on Solea senegalensis culture: effects on growth and molecular markers of stress.

Aquaculture routine practices may cause stress induction on the fish and compromise their welfare affecting the production. This experiment aimed to evaluate the potential links between handling during culture with stress responses and growth on Senegalese sole (Solea senegalensis). We worked with two fish cohorts in terms of initial body weight and culture stage: Trial 1 included specimens in the fattening stage (226 ± 4.

Stress decreases spermatozoa quality and induces molecular alterations in zebrafish progeny.

Background: Chronic stress can produce a severe negative impact on health not only in the exposed individuals but also in their offspring. Indeed, chronic stress may be contributing to the current worldwide scenario of increasing infertility and decreasing gamete quality in human populations. Here, we evaluate the effect of chronic stress on behavior and male reproductive parameters in zebrafish.

Identification and characterization of the EXPA7, EXPA18 and EXT10 genes in Turbinicarpus lophophoroides (Werderm.) Buxb. & Backeb; and their expression analysis in the root under abiotic stress.

Expansin and extensin are proteins involved in resistance to various abiotic stresses by processes of cell wall modification and in the formation and elongation of the hairy root. They are located in several organs of the plant included root epidermis. Turbinicarpus lophophoroides is a cactus model to studies these genes in adventitious and transformed roots.

Flow Cytometry and Confocal Microscopy for ROS Evaluation in Fish and Human Spermatozoa.

Reactive oxygen species (ROS) could have a negative impact on sperm cellular function and viability. This chapter describes a protocol for oxidative stress evaluation using dichlorofluorescein (DCF) which can specifically reveal intracellular reactive oxygen species. The protocol described here has been used in human and teleost species sperm samples.
