Lysozyme-like activity in eggs and in some tissues of land snails Helix aspersa maxima and Achatina achatina

Folia Biologica, 2004
Antibacterial lysozyme-like activity against Micrococcus luteus in eggs and some tissues of snails Helix aspers maxima and Achatina achatina was detected in a turbidimetric standard assay. The bacteriolytic activity in Helix aspersa maxima was higher than in Achatina achatina. After the application of the bioautography technique, several lytic zones of

The shell matrix of the pulmonate land snail Helix aspersa maxima.

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2012
In mollusks, the shell mineralization process is controlled by an array of proteins, glycoproteins and polysaccharides that collectively constitute the shell matrix. In spite of numerous researches, the shell protein content of a limited number of model species has been investigated.

Helix aspersa maxima mucus exhibits antimelanogenic and antitumoral effects against melanoma cells.

Biomedicine & Pharmacotherapy, 2018
Snail secretion is currently revolutionizing the world of cosmetics and human skin care. The efficacy of snail secretion in wounds healing has been proven both in vitro and by clinical studies. However, the potential anti-tumor effect of snail secretion was poorly investigated. In this report, our in vitro study showed that Helix aspersa maxima species

Shell of snail Helix aspersa maxima (Helicidae) as a protection of bioaccumulation toxic sodium fluoride in soft tissue.

Folia Biologica, 2005
The aim of this work was to determine the extent of bioaccumulation of sodium fluorides in tissues of snails under strictly controlled conditions, and also to determine resistance and tolerance to sodium fluoride load in these organisms. The study was performed on snails removed from aestivation. Quantitation of fluoride levels was done in soft tissues

Effects of feed protein and lipid contents on fatty acid profile of snail (Helix aspersa maxima) meat

Journal of Food Composition and Analysis, 2006
The purpose of the present work is to verify the influence of different feed protein and lipid contents on the proximate composition on the fatty acid profile of snail meat (Helix aspersa maxima). The predominant fatty acids were palmitic (16.0), estearic (18:0), oleic (18:1 n-9), linoleic (18:2 n-6), mead (20:3 n-9), and arachidonic (20:4 n-6) acids ...

Influence of diets enriched with different vegetable oils on the fatty acid profiles of snail Helix aspersa maxima

Food Chemistry, 2003
Abstract The proximate analyses and fatty acid profiles of snail (Helix aspersa maxima) muscle submitted to different feedings with diets enriched with 3% of different vegetable oils (canola, soybean, flaxseed, sunflower, maize and rice) were analysed. The lowest value of lipids was in the snail muscle of the treatment enriched with soybean oil.
