Summary: This study evaluated the effect of the light-dark cycle on energy expenditure indicators for two species of Amazonian fish. The results show that certain hematological parameters exhibit daily rhythms, which may be related to the greater energy demand during the day for these species.

Summary: The study evaluated the susceptibility of Neotropical freshwater fish to Roundup Transorb and found that sublethal exposure can induce oxidative stress in the liver, gills, and white muscle. Even at environmentally relevant concentrations, short-term exposures to Roundup Transorb may have adverse impacts on fish species.

Summary: Research indicates that small matrinxas quickly start the anabolic process in the postprandial period, while in larger tambaqui, it occurs late but with a longer duration. Additionally, matrinxa exhibits higher basal nitrogen excretion, which increases rapidly after feeding.

Summary: This study evaluated the effects of dietary supplementation with Minthostachys mollis essential oil on growth, fillet composition, hematological parameters, and disease resistance in juvenile Brycon amazonicus. The results showed that the supplementation did not significantly affect growth and hematological parameters, but had an effect on fillet composition and glucose levels.

Summary: The rise in water temperature in the Amazon River has raised concerns about the impact on commercially important fish species like matrinxa. Research has shown that diets supplemented with nerolidol can prevent oxidative damage and maintain fatty acid profiles in fish exposed to heat stress. This study highlights the potential of nerolidol-supplemented diets as a strategy to mitigate heat stress-induced damage and maintain fish health.

Summary: This study aimed to determine the KYN to TRP ratio as a biomarker of acute stress in fish, and found that the KTR in fish liver and brain significantly increased at 48 hours post-stress exposure. Additionally, cortisol responded more quickly to the stress stimulus compared to KYN and TRP in fish tissues.

Summary: Studies have shown that supplementing amino acids not commonly found in poultry diets can optimize productivity, immune system, antioxidant status, and meat and egg quality. Tryptophan (Trp) plays a crucial role in protein anabolism and indirectly affects hormone secretion and immune organ development. This review discusses the importance of Trp in poultry production and suggests further research areas to address information gaps.

Summary: Peripheral serotonin levels have an influence on brain functions under basal and dynamic situations. The lack of peripheral serotonin can reduce anxiety-like behavior, as well as neuronal activation and the expression of brain plasticity-related genes.

Summary: Blood vessel abnormalities in cancer can be targeted therapeutically to suppress cancer progression, according to a study. Researchers found that a molecule called fibronectin leucine-rich transmembrane protein 2 (FLRT2) is expressed in abnormal blood vessels of advanced colorectal cancers in humans. Deleting FLRT2 in endothelial cells selectively pruned abnormal blood vessels and suppressed tumor metastasis. Additionally, FLRT2 deletion increased the number of mature vessels, enhancing the antitumor effects of immune checkpoint blockers. The study suggests that targeting tumor-specific interendothelial adhesions could be a safe and effective therapeutic option.

Summary: To adapt to changing environments, plants have evolved regulatory mechanisms that balance their growth and stress responses. This study reveals the involvement of tryptophan synthase beta subunit 1 (TSB1) in coordinating the growth hormone auxin and the stress hormone abscisic acid (ABA), thereby affecting plant growth and abiotic stress responses. TSB1 serves as a key coordinator by balancing Trp and ABA homeostasis.

Summary: This study aimed to investigate the effects of dietary tryptophan supplementation on the immune condition of European seabass during stressful rearing conditions and their response to bacterial pathogens. The results showed that stress did not compromise the health indicators of seabass, but exacerbated the inflammatory response. Tryptophan had minimal effects on immune indicators but improved the inflammatory response against bacterial pathogens during stressful conditions.

Summary: The study found that stress leads to a transient reduction in innate immune system activity and activates hemolytic activity of the complement system, as well as increases lysozyme concentration. Additionally, stress induces oxidative stress in the liver, and modulates the antioxidant system differently under different conditions by enhancing SOD activity while impairing CAT and GSH-Px activity.

Summary: The study investigated the effects of oral hydrocortisone and acute stressor on stress, immune responses, and antioxidant system responses in juvenile Piaractus mesopotamicus. The findings showed that exposure to stressor and HC impacted circulating glucose, cortisol levels, and immune responses, while differences in biomarkers indicated that exogenous hormone was unable to precisely replicate stress responses.

Summary: The sustainability of aquaculture is affected by environmental changes, such as temperature fluctuations, which can disrupt the physiological balance of fish. In this study, we assessed the stress, immune, and antioxidant responses of pacu exposed to sudden temperature drops commonly experienced in pacu farming regions. The results showed that pacu exhibited immune activation and oxidative stress in response to the temperature drop, but was able to activate compensatory mechanisms to mitigate tissue damage. This study provides valuable insights for pacu management during periods of thermal changes.
