Probiotic-based adsorbent mitigates aflatoxin B1 toxicity in Piaractus mesopotamicus: assessing well-being via changes in tissue architecture and digestive enzyme activity.

Aflatoxin is a mycotoxin produced by fungi of the genus Aspergillus that is present in various foods. Probiotics are well-established products in aquaculture, and due to their effective contribution to the intestine, they can be used as an aflatoxin adsorbent. This study evaluated the effects of aflatoxin B1 (AFB1) on enzymatic activity and intestinal function in Piaractus mesopotamicus (pacu) fingerlings fed diets containing a probiotic-based adsorbent (PBA).

Effect of increasing lipid levels on liver metabolism, intestinal morphology and production performance of discus fish (Symphysodon aequifasciatus).

The objective of this study was to evaluate the effects of three levels of lipids in the diet on growth, metabolism, and intestinal and hepatic histopathology in discus fish (Symphysodon aequifasciatus). Fish were stocked in quadruplicate in aquarium (50L) and were fed experimental diets containing three levels (3%, 10%, and 14%) of dietary lipids (LP). At the end of the trial, no significant differences in growth performance were observed.

Impact of strength-based video-feedback intervention on maternal sensitivity in mother-infant dyads with maternal depressive symptoms.

Strength-based video-feedback (SB-VF) is an attached base and culturally sensitive video-feedback intervention which promotes maternal well-being and sensitivity through using mentalization technics. The goals of this study were to investigate the feasibility, acceptability, and preliminary effectiveness of internet-delivered SB-VF to mother with post-partum depression during COVID-19 pandemic. A pilot randomized, two arm controlled trial was conducted (trial registration NCT04748731) with depressive symptoms' women (n = 172) from Chilean public primary health centers, 79 were randomized to either experimental group (on-line SB-VF plus treatment as usual [TAU], n = 41) or control group (TAU, n = 38).

Sustained swimming and improvements in anti-oxidative stress responses in matrinxa (Brycon amazonicus) exposed to environmental nitrite.

Nitrite is usual in water of intensive rearing systems. Considering its oxidative harmful potential, it was selected to challenge matrinxa Brycon amazonicus reared in sustained swimming (SS) (with flowing water adjusted to speed at 1.0 BL seg (long-duration aerobic metabolic characteristic) and evaluate any beneficial effect of such rearing system to enhance the fish potential to cope with this oxidant stressor in fish farmings.

Tranquilizing and hepatoprotective effects of red-eye tetra (Moenkhausia Forestii) diet fed with Erythrina crista-galli.

This study aimed to assess the leaf aqueous extract composition of Erythrina crista-galli and the effects of its inclusion on the diet of red-eye tetra (Moenkhausia forestii), concerning enzyme content of digestive, hepatic, and oxidation metabolism and pigmentation. Fish (1.78 ± 0.
