AI Article Synopsis

  • The study identified the presence of ACTH and similar receptor-like molecules in various tissues of the sea bass, Dicentrarchus labrax, at multiple developmental stages post-hatching (2 to 24 days).
  • Both ACTH and its receptor-like molecules were found to share a similar distribution across different tissues, indicating their potential importance in developmental processes.
  • LPS treatment at specific stages (8 and 24 days post-hatching) triggered the release and induction of ACTH-like molecules, highlighting their role in regulating body homeostasis during the early life of the fish, especially before lymphoid cell maturation occurs by 30 days post-hatching.

Article Abstract

ACTH and ACTH receptor-like molecules were found at the examined stages of development (2, 4, 8, 12, 18, and 24 days post-hatching) in yolk sac, pronephros tubules, interrenal tissue, thymus, liver, spleen, cardinal veins, and skin of the teleost fish Dicentrarchus labrax. ACTH and the related receptor-like molecules show a similar distribution. LPS treatment at two different stages (8 and 24 days post-hatching) provoked both a release and an induction of ACTH-like molecules, suggesting an important role of this peptide to control the modifications in body homeostasis during the first period of the sea bass' life, i.e., 30 days post-hatching, before the lymphoid cells have reached complete maturation.

Emerging evidence indicates a close relationship between gut microbiota and fatty liver disease. It has been suggested that gut microbiota modulation with probiotics ameliorates fatty liver disease in rodents and humans, yet it remains unclear whether the same results will also be obtained in poultry. The aim of this study was to investigate whether a mixture of probiotics supplemented after hatching can prevent CORT-induced fatty liver disease in broilers, and to determine how such effects, if any, are associated with hepatic de novo lipogenesis and gut microbiota composition.

The inherent deficiency of phospholipids in limits its nutritional value as live prey for marine fish larvae. In our previous study, we optimized a phospholipid enrichment method by incubating nauplii with 10 g of soybean lecithin per m of seawater for 12 h, significantly enhancing their phospholipid content. : The present study evaluated the impact of this enrichment on yellow drum () larvae, focusing on growth performance, intestinal morphology, body composition, weaning success, and desiccation stress resistance.

Histological Changes of the Mucosal Epithelium in the Chicken Intestine during Pre- and Post-Hatching Stages.

J Poult Sci

January 2025

Laboratory of Animal Functional Anatomy (LAFA), Faculty of Agriculture, Shinshu University, Kami-ina, Nagano 399-4598, Japan.

This study clarified the histological changes in the mucosal epithelium of the chicken intestine during the pre- and post-hatching stages. The duodenum, jejunum, ileum, and colorectum were collected from embryos at 15, 17, 18, 19, and 21 days of incubation and from chicks at 1 and 3 days after hatching. Paraffin sections prepared from tissue samples were stained with periodic acid-Schiff followed by alcian blue for histological analysis and to detect goblet cells.

Osmoregulation affects elimination of microplastics in fish in freshwater and marine environments.

January 2025

Graduate School of Frontier Sciences, The University of Tokyo, Kashiwa 277-8563, Chiba, Japan; Atmosphere and Ocean Research Institute, The University of Tokyo, Kashiwa 277-8564, Chiba, Japan.

In recent decades, microplastics (MPs) have emerged as one of the biggest environmental challenges in aquatic environments. Ingestion and toxicity of MPs in seawater (SW) and freshwater (FW) fish have been studied extensively both in field and laboratory settings. However, the basic mechanism of how fish deal with MPs in SW and FW remains unclear, although physiological conditions of fish differ significantly in the two environments.
