The importance of using local species in ecotoxicological studies: nematodes of Amazonian occurrence vs. Caenorhabditis elegans in the analysis of lethal and sublethal effects of aluminium.

It is recognized that in bioassays, especially those conducted for ecotoxicological purposes, preference should be given to the use of species that are adapted to the physical-chemical conditions of the environment to be monitored. However, to establish the use of alternative species instead of the standardized ones, it is recommended to carry out tests to assess/compare their sensitivity to contaminants. This study assessed the lethal and sublethal effects (growth, fertility, and reproduction) of different aluminium concentrations, including environmentally relevant concentrations recorded in the Amazon, on two nematode species (C.

Relation between shape-tailored CeO nanoparticles morphology and hemocompatibility and antimicrobial effect.

Cerium is one of the most studied rare elements whose oxidative state (Ce and Ce) can be changed in different environments. Cerium oxide nanoparticles (CeO NPs), which are nevertheless more complex chemical structures, are nowadays very exciting entities involved in the biomedical field, particularly in the four stages of wound healing. In the first stage, called hemostasis, several issues such as the required morphology to be biologically efficient, and the effect of Ce and Ce on the applicability potential of CeO NPs remain unclear.

Resection of Primary Leiomyosarcoma of the Inferior Vena Cava and Reconstruction with a Cadaveric Homograft.

The effect of nanoceria on the alginate-gum arabic crosslinking mechanism and in vitro behavior as a wound dressing.

Medical practice has proven that chronic wounds can be treated successfully if the dressing is chosen according to the healing phase of the wound. Correct intervention from the hemostasis and inflammatory phase can prevent oxidative stress and ensure optimal conditions for healing. It is important to design a new wound dressing that does not cause additional injury, has an antioxidant effect, removes dead cells, and promotes wound healing.
