Structure and fracture resistance of alligator gar (Atractosteus spatula) armored fish scales.
The alligator gar is a large fish with flexible armor consisting of ganoid scales. These scales contain a thin layer of ganoine (microhardness ~2.5 GPa) and a bony body (microhardness ~400 MPa), with jagged edges that provide effective protection against predators. We describe here the structure of both ganoine and bony foundation and characterize the mechanical properties and fracture mechanis...
متن کاملFine Structure of the Gas Bladder of Alligator Gar, Atractosteus spatula
Anthropogenic factors seriously affect water quality and adversely affect fish populations. Agricultural run-off accumulates in the Mississippi River and the coastal estuaries. Alligator gar (Atractosteus spatula) inhabits these waters and is impacted by agricultural pollution, petrochemical contaminants and oil spills. These fish are bimodal air breathers, and use a primitive lung as an access...
متن کاملCloning of the growth hormone cDNA of alligator gar Atractosteus spatula and its expression through larval development.
The alligator gar (Atractosteus spatula) is the largest freshwater fish inhabiting rivers draining into the Gulf of Mexico. This primitive fish shows a fast growth rate since its early larval stages. This is attributed to the action of growth hormone (GH), an anterior pituitary gland hormone responsible for linear growth in vertebrates that can also be expressed in extrapituitary adult tissues ...
متن کاملBlood and tissue levels of diazinon in rabbit following a subacute dermal exposure to incremental doses
BACKGROUND:Uncontrolled application of diazinon (DZN)can cause environmental contamination and adverse healtheffects on humans or animals. OBJECTIVES:This study aimed toinvestigate the toxic effects and the level of DZN in serum andtissues of rabbits following a sub acute dermal exposure totoxicant. METHODS:Different doses of DZN were applied dailyto New Zealand rabbits through the ear skin in ...
متن کاملChanges in Liver Contents of Lipid Fractions Following Titanium Exposure
The potential to cause tissue damage by metal ions is the matter of widespread investigation. Titanium salts are widely used in industry for ceramic painting, in pharmacy for tablet coating and making chemical sunscreens and in medicine as photo catalysts with bactericidal activity. This may address the idea that the exposure to these salts could play a role in metabolic disorders. In this stud...
