Fasciolosis is a worldwide distribution zoonosis that causes great damage in ruminant breeding and has the aquatic mollusc as an intermediate host. Synthetic molluscicides are the most used for control; however, they are harmful to fauna and flora. Therefore, this study aimed to evaluate the effect of essential oils from , , and terpene carvacrol, on adult molluscs and eggs of . Analysis of EO volatile components was carried out on a gas chromatograph equipment coupled with mass spectrometry selective detector. The studied components were diluted in concentrations of 10, 20, 40, 60, 80 and 100 ppm, and it was observed that at concentrations of 60, 80 and 100 ppm, carvacrol at the concentrations of 80 and 100 ppm, and at a concentration of 80 ppm led to 100% mortality of molluscs. All concentrations the substances tested showed 100% ovicidal activity.

This case describes a patient with pancreatic exocrine insufficiency and persistently elevated serum vitamin B12 concentrations that were not due to supplementation or associated with hepatic or hematological pathology. Laboratory investigations suggested the presence of macro-B12 as the cause of this patient's raised serum vitamin B12. Macro-B12 is often formed when vitamin B12-vitamin binding proteins (transcobalamin and haptocorrin) complex with immunoglobulins.

The Impact of Selenium on the Physiological Activity of Yeast Cells ATCC 7090 and CCY 20-2-26.

Front Biosci (Landmark Ed)

January 2025

Department of Food Biotechnology and Microbiology, Institute of Food Sciences, Warsaw University of Life Sciences - SGGW, 02-776 Warsaw, Poland.

Background: This study investigated the selenium-binding capacity of the biomass of two yeast strains, American Type Culture Collection (ATCC) 7090 and CCY 20-2-26.

Methods: The studies carried out methods of bioaccumulation by yeast biomass. Inorganic selenium was added to the culture media as an aqueous solution of NaSeO at concentrations ranging from 0 to 40 mg Se/L.

Background: Observation, execution, and imitation of target actions based on mirror neuron network (MNN) have become common physiotherapy strategies. Electrical stimulation (ES) is a common intervention to improve muscle strength and motor control in rehabilitation treatments. It is possible to enhance MNN's activation by combining motor execution (ME) and motor imitation (MI) with ES simultaneously.

Introduction: The effects of remimazolam (Re) in combination with andrographolide (AP) on learning, memory, and motor abilities in rats following cardiopulmonary bypass (CPB) surgery were studied.

Methods: We hypothesized that the combination of Re and AP could improve postoperative cognitive dysfunction (POCD) in rats after CPB by modulating nervous system inflammation. Cognitive function was assessed using the Morris Water Maze test, and the concentrations of tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6) in serum were measured by enzyme-linked immunosorbent assay (ELISA).

The environmental impact of chemicals used in aquaculture, particularly nitrofurantoin, has raised global concern. Nitrofurantoin, a broad-spectrum antimicrobial, is commonly used in aquaculture despite safety risks. Determination of nitrofurantoin in water samples of fish ponds is necessary to ensure the safety and quality of seafood.
