Artemia salina Toxicity Assay: Standardization in a 24‐Well Microplate

Environmental Toxicology, EarlyView.
ABSTRACT Bioassays with Artemia sp. are widely used in aquatic, environmental, and human toxicology as an initial tool to investigate the toxicity of plant extracts, isolated compounds, drugs, and products of natural or synthetic origin. These assays allow for the estimation of the median lethal concentration (LC50) and guide subsequent studies in ...

Age sensitivity of osmoregulation and of its neural correlates in Aplysia

, 1989
Osmoregulation was studied in the marine mollusc Aplysia californica in young, mature, and old adults. To monitor volume and osmoregulation, we measured body weight, hemolymph osmolality, and chloride concentration.

Yeast osmoregulation – glycerol still in pole position

, 2022
In response to osmotic dehydration cells sense, signal, alter gene expression, and metabolically counterbalance osmotic differences. The main compatible solute/osmolyte that accumulates in yeast cells is glycerol, which is produced from the glycolytic ...

Growth, Physiological Response, and Gill Health of Spotted Rose Snapper (Lutjanus guttatus) Reared at Different Salinities

Fishes
The physiological and gill health responses of juvenile spotted rose snapper (Lutjanus guttatus) were evaluated at four salinities—8, 16, 24, and 32‰—over a 70-day period.

Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

Environmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

Evaluating How Growth and Diet of Native Freshwater Fishes Change in Response to Salinity and pH in a Semi-Arid Landscape

Fishes
Freshwater ecosystems are increasingly stressed by drought and anthropogenic inputs that can increase specific conductivity (SPC) and pH; however, little is known about how harsher conditions affect fish. We evaluated how fish growth and diet composition

Secretion and Function of Pituitary Prolactin in Evolutionary Perspective

Frontiers in Neuroscience, 2020
The hypothalamo-pituitary system developed in early vertebrates. Prolactin is an ancient vertebrate hormone released from the pituitary that exerts particularly diverse functions.

Prostaglandin E2 (PGE2) signaling regulates fluid excretion and uric acid metabolism in the mosquito Anopheles gambiae

Insect Science, EarlyView.
Prostaglandin E2 (PGE2) signaling via its receptor has integral roles in mosquito physiology, mediating fluid excretion, stimulating hindgut contractions, and in modulating uric acid levels. Together, these results uncover previously unrecognized roles of prostaglandin signaling in osmotic balance and metabolic homeostasis in mosquitoes.
