Paclobutrazol (PBZ), a fungicide widely used as growth regulator in plants, is often detected in surface waters, posing potential risks to aquatic life. While its toxicity in adult fish is known, effects on early-life stages remain underexplored. The study evaluated the effect of PBZ on zebrafish (Danio rerio) embryos/larvae and the potential protective role of zinc-doped cadmium sulphide nanoparticles (Zn-CdS NPs) synthesized using Hypsizygus ulmarius mushroom extract.

This research investigates the eco-friendly synthesis of silver nanoparticles (AgNPs) utilizing the aqueous extract of Morus spp. (Mulberry) fruit as a natural bio-reducing and stabilizing agent. The mulberry fruit-mediated silver nanoparticles (MF-AgNPs) were primarily spherical, with particle sizes between 20 and 100 nm, as verified by electron microscopy and particle size characterization respectively.

A variety of bacteria, including beneficial probiotic lactobacilli, produce antibacterials to kill competing bacteria. Lactobacilli secrete antimicrobial peptides (AMPs) called bacteriocins and organic acids. In the food industry, bacteriocins, but even whole cell-free supernatants, are becoming more and more important as bio-preservatives, while, in orthopedics, bacteriocins are introducing new perspectives in biomaterials technologies for anti-infective surfaces.

Aquatic ecosystems cover more than two-thirds of the Earth's surface and play a vital role in maintaining a stable global temperature and providing various benefits to an expanding human population. However, human activities are causing negative effects on these ecosystems. Particulate matter (PM) refers to tiny particles with a variable composition and a diameter of <100 μm.

The effect of green tea (Camellia sinensis) iron oxide nanoparticles (nano-Fe) on the effectiveness, growth, antioxidant capacity, and immunological response of Trichogaster trichopterus (Blue gourami) fingerlings was investigated. UV-Visible, Fourier Transform Infrared, Scanning Electron Microscopy, Energy Dispersive X-ray, X-ray diffraction, Dynamic Light Scattering, and Zeta Potential spectroscopy were used to evaluate the biologically synthesized nano-Fe. Characterization revealed the hexagonal and spherical morphology with an average diameter of 114 nm.

Mesenchymal stromal cells (MSCs) were isolated from (DB) and studied for their final cellular product measures, such as safety, purity, quality, quantity, and integrity that are ascribed as cellular products. This research aimed to isolate MSCs for expansion under the clinical scale level with potency, secretion of cytokines, growth factors secreted by DB-MSCs, and their role in wound healing. Placentas isolated from DB were expanded up to the 10th passage, and their characteristics were assessed by phenotypic characterization using a flow cytometer and analyzed for trilineage differentiation by cytochemical staining.
