Aquaculture Nutrition, Volume 2026, Issue 1, 2026.The conjugation states of bile acids (BAs) have been demonstrated to affect BAs regulatory functions. This study aimed to investigate the effects of conjugated or non‐conjugated BA additions on growth performance, liver health, and BA metabolism in pearl gentian grouper (Epinephelus lanceolatus♂ × E.

Osmotic Effects on Mitochondria from Two Species of Amphibian, Bufo marinus and Rana catesbeiana
, 1991 The effects ql ionic and/or osmotic change on skeletal muscle mitochondrial performance were investigated. Two substrates, pyruvate and glutamate, and variation in osmotic pressure from 205 to 360 mosm in KCl or mannitol/sucrose media had no effect on ...

Analysis of the Rana catesbeiana tadpole tail fin proteome and phosphoproteome during T3-induced apoptosis: identification of a novel type I keratin [PDF]
, 2007 BioMed CentralBackground: Thyroid hormones (THs) are vital in the maintenance of homeostasis and in the control of development. One postembryonic developmental process that is principally regulated by THs is amphibian metamorphosis.

Glomerular permeability in the bullfrog Rana catesbeiana. [PDF]
The Journal of cell biology, 1978 Filtration studies suggest similar size pores in the glomerular filters of mammals and amphibians. However, the glomerular wall in the bullfrog exhibits several structural features not found in mammals. The subendothelial space of the basement membrane is often greatly enlarged and infiltrated by cellular elements.

Removing invasive stream macrofauna shifts nontarget invertebrate mesofauna through facilitation
Ecosphere, Volume 16, Issue 12, December 2025.Abstract Positive interactions among non‐native species can drive invasional meltdowns to the detriment of native biota. Here, we assessed whether targeted control of aquatic invasive species (AIS) can benefit native species by eliminating synergies among invaders.

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 10, Page 1191-1204, December 2025.ABSTRACT Peroxisome proliferator‐activated receptors (PPAR) are master transcriptional regulators that maintain metabolic homeostasis in vertebrates. Amphibians are often exposed to endocrine disrupting compounds (EDCs) that could dysregulate lipid metabolism.
