Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

Environmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...

Regulation of bicarbonate secretion in marine fish intestine by the calcium-sensing receptor [PDF]

, 2018
In marine fish, high epithelial intestinal HCO3- secretion generates luminal carbonate precipitates of divalent cations that play a key role in water and ion homeostasis.

Rearing Time–Salinity Synergy in Osmoregulation: Ionic Homeostasis and Textural Enhancement in Adult Freshwater Drums (Aplodinotus grunniens)

Fishes
This study demonstrates that rearing duration (14 and 30 days) and environmental salinity (0, 4, 8, and 12 parts per thousand (ppt) of NaCl) synergistically modulate osmoregulation and muscle texture in adult freshwater drums (Aplodinotus grunniens ...

Effects of salinity and hypoxia-induced hyperventilation on oxygen consumption and cost of osmoregulation in the estuarine red drum (Sciaenops ocellatus).

Comparative biochemistry and physiology. Part A, Molecular & integrative physiology, 2018
Understanding the physiological responses of fishes to salinity changes and aquatic hypoxia is essential for the conservation of marine species. Salinity changes affect the osmotic gradient across the gill epithelium, while hypoxia increases gill ...

Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

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.

Glutamate uptake is important for osmoregulation and survival in the rice pathogen Burkholderia glumae

PLoS ONE, 2018
Bacteria exhibit an optimal growth rate in culture media with sufficient nutrients at an optimal temperature and pH. In addition, the concentration of solutes plays a critical role in bacterial growth and survival.

Contrasting CO2‐response strategies in Pardina lentils: Yield maximization in a commercial cultivar and seed composition adjustment in a landrace

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Assessing crop's responses to elevated carbon dioxide (eCO2) is crucial for global food security. This study examines the impact of eCO2 (700 μmol mol−1) on the cultivars of lentil (Lens culinaris), local Pardina Verde Rayada lentil (PVRL), and commercial Pardina lentil (PL) in terms of the productivity and nutritional composition ...

The Influence of the Zebra Mussel (Dreisena Polymorhpa) on Magnesium and Calcium Concentration in Water [PDF]

, 2010
In this study we examined changes in magnesium and calcium ion concentrations depending on Zebra Mussel biomass, pH values and temperature. We performed field experiments in years with different weather conditions using twelve 200 litre polycarbonate ...

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
