Risperidone is an antipsychotic medication used in the treatment of conditions like autism and schizophrenia. The goal of the current study was to examine the effects of risperidone in zebrafish embryos ( ) with regard to survival, development, and cardiac and neural systems. The results showed that concentrations above 100 μM were associated with deaths, teratogenic effects, and cardiotoxic and neurotoxic effects.

Inbred species are useful resources for a variety of biomedical research applications. To create isogenic zebrafish, it is feasible to stop meiosis II (repeatedly) or mitosis (two times) in a haploid embryo by applying pressure or by delivering a heat shock, respectively. In this study, to improve the repeatability, we suggest a less complicated approach based on sperm ultraviolet-C (UV-C) exposure for a shorter period followed by heat shock at various temperatures, eliminating the use of pressure in meiotic therapy since heat shock is more accessible to laboratories.

The salt calcium chloride (CaCl₂) is widely used in industry as a food additive; levels for human consumption are regulated by international or governmental agencies. Generally, the food industry relies on toxicity studies conducted in mammals such as mice, rats, and rabbits for determining food safety. However, testing in mammals is time-consuming and expensive.

Zebrafish is considered an unprecedented animal model in drug discovery. A review of the literature presents highlights and elucidates the biological effects of chemical components found in Cannabis sativa. Particular attention is paid to endocannabinoid system (eCB) and its main receptors (CB1 and CB2).

Artemisinin extracted from Artemisia annua L. plants has a range of properties that qualifies it to treat several diseases, such as malaria and cancer. However, it has short half-life, which requires making continuous use of it, which has motivated the association of artemisinin (ART) with polymeric nanoparticles to increase its therapeutic efficiency.

Mucoadhesive polymeric nanocapsules have attracted interest of researchers from different fields from natural sciences because of their ability to interact with the mucosa and increase drug permeation. Anesthesia by immersion causes absorption through the skin and gills of fish, so it is important to evaluate the exposure of these organs to drug nanosystems. Benzocaine (BENZ) is one of the most popular anesthetic agents used in fish anesthesia, but it has drawbacks because of its low bioavailability, resulting in weak absorption after immersion.

Much of medical research relies on animal models to deepen knowledge of the causes of animal and human diseases, as well as to enable the development of innovative therapies. Despite rodents being the most widely used research model worldwide, in recent decades, the use of the zebrafish () model has exponentially been adopted among the scientific community. This is because such a small tropical freshwater teleost fish has crucial genetic, anatomical and physiological homology with mammals.
