Toxic effects of Helix aspersa snail egg hydrolyzates obtained by static in vitro digestion on Caco-2 colorectal adenocarcinoma cells.

Colorectal cancer is the third most common cancer. Anticancer compounds obtained after the digestion of snail eggs may hurt the growth and development of colon cancer cells. The research aimed to prepare hydrolyzates from Helix aspersa maxima and Helix aspersa aspersa snail eggs using static in vitro simulation of gastrointestinal digestion.

Green Synthesis of Silver Nanoparticles from Aqueous Extract and Their Effect on and Chicken Embryo Growth.

Silver nanoparticles (AgNPs), synthesised using algal extract and silver nitrate, are studied in medicine for their antibacterial properties in poultry. This study assessed the effect of AgNPs on bacterial inhibition and early development and blood parameters in Ross 308 chicken embryos. AgNPs were characterised using transmission electron microscopy, scanning electron microscopy with a focused ion beam, UV-Vis spectroscopy, and a zetasizer.

The impact of relaxation music (Weightless by Marconi Union) on production performance, welfare, and hematological and biochemical blood parameters in broiler chickens.

The study evaluated the impact of relaxation music on the production performance, welfare, and blood parameters of broiler chickens. Literature indicates that specific music genres, as environmental enrichment, can improve animal welfare and production outcomes. The research involved 1,200 Ross 308 chickens divided into control (C) and experimental (M) groups.

Fullerenol C(OH) Nanoparticles and Ectoine Protect Human Nasal Epithelial Cells Against the Cytokine Storm After Addition of the Full-Length Spike Protein from SARS-CoV-2.

Introduction And Objective: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) enters the nasal cavity, penetrates the nasal epithelial cells through the interaction of its spike protein with the host cell receptor angiotensin-converting enzyme 2 (ACE2) and then triggers a cytokine storm. We aimed to assess the biocompatibility of fullerenol nanoparticles C(OH) and ectoine, and to document their effect on the protection of primary human nasal epithelial cells (HNEpCs) against the effects of interaction with the fragment of virus - spike protein. This preliminary research is the first step towards the construction of a intranasal medical device with a protective, mechanical function against SARS-CoV-2 similar to that of personal protective equipment (eg masks).

Silica-Calcite Sedimentary Rock (Opoka) Enhances the Immunological Status and Improves the Growth Rate in Broilers Exposed to Ochratoxin A in Feed.

Mycotoxins, such as Ochratoxin A (OTA), originating from fungi like Aspergillus and Penicillium, represent serious health hazards to poultry. The use of mycotoxin-adsorbing feed additives can reduce these risks. Opoka, a porous transitional rock, shows promise as one of these additives.
