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 ...

Brine Shrimp Integration in Hydroponics: The Role of Brine Shrimp in Nutrient Optimization

INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT
This research investigates the potential benefits of integrating brine shrimp (Artemia spp.) into hydroponic systems to enhance plant growth through increased nitrogen availability. Over a 30-day simulation, plants were monitored for growth patterns with brine shrimp supplementation.

From Consumer Plastics to Aquatic Toxicants: Oxidative and Endocrine Effects of Microplastics on Fathead Minnow (Pimephales promelas) Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Secondary microplastics (MPs) from single‐use consumer products are rapidly becoming one of the most persistent and widespread pollutants of our time. Freshwater systems act as early sinks for MPs where fragmentation and additive leaching expose aquatic life to a broad spectrum of toxic compounds.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Absence of a Hectocotylus and Associated Mating Behaviour in the Paintpot Cuttlefish Ascarosepion tullbergi

Acta Zoologica, EarlyView.
ABSTRACT A hectocotylus is a sexually modified arm used by males of some cephalopod species to transfer spermatophores to females. In most cuttlefish (Sepiidae), it corresponds to the left arm IV, in which basal suckers are reduced or absent; this modification is thought to facilitate sperm transfer without premature rupture, which could be caused by ...

The Effect of Familiarity Among Social Partners on the Jumping Behavior of Amazon Mollies

Ethology, EarlyView.
Pairs of familiar or nonfamiliar clonal Amazon mollies were tested in individual bowls, from which they could only escape from by jumping. Familiar pairs remained together significantly more than non‐familiar ones. Other behavioral aspects, such as timing and direction of jumps was not affected by familiarity.

In Vitro Anti-Inflammatory, Anticancer (MCF-7, 3T3, and HeLa Cell Lines), and Brine Shrimp Lethality Assay and FTIR Analysis of the Extract and Fractions of the Whole Plant of Heliotropium europaeum

Mediators of Inflammation, 2020
In this study, anti-inflammatory, anticancer, brine shrimp lethality, and FTIR studies were evaluated. The oxidative burst assay using the chemiluminescence technique, MTT assay, brine shrimp lethality assay, and FTIR analysis were the methods used for ...

Breaking the ice: multiple origins of ice‐binding/antifreeze proteins

The FEBS Journal, EarlyView.
Ice‐binding proteins (IBPs) evolved independently in many organisms during Cenozoic cooling and glaciation. In flounders, α‐helical IBPs evolved from an antiviral protein, while similar IBPs arose independently from different progenitors in three other fish lineages.

Nucleotide Metabolism during Brine Shrimp Embryogenesis

Journal of Biological Chemistry, 1967
Changes in the amounts of acid-soluble nucleotides during embryonic development of the encysted egg of the brine shrimp, Artemia salina, have been determined. Significant quantities of diguanosine tetraphosphate, the most abundant compound in the nucleotide pool, are apparently not utilized until hatching, at which time the amount falls precipitously ...
