Phototoxicity: Its Mechanism and Animal Alternative Test Methods
The skin exposure to solar irradiation and photoreactive xenobiotics may produce abnormal skin reaction, phototoxicity. Phototoxicity is an acute light-induced response, which occurs when photoreacive chemicals are activated by solar lights and transformed into products cytotoxic against the skin cells. Multifarious symptoms of phototoxicity are identified, skin irritation, erythema, pruritis, ...
متن کاملOcular phototoxicity.
The human eye is constantly exposed to sunlight and artificial lighting. Therefore the eye is exposed to UV-B (295-320 nm), UV-A (320-400 nm), and visible light (400-700 nm). Light is transmitted through the eye and then signals the brain directing both sight and circadian rhythm. Therefore light absorbed by the eye must be benign. Damage to the young and adult eye by intense ambient light is a...
متن کاملThe review of pathogenic mechanism of Aeromonas hydrophila and action of tetracycline against it in aquatic animals
Aeromonas hydrophila is one of common bacterial disease in aquatic animals and its outbreak cause to decrease of aquatic production. Aeromonas disease is due to a protein toxin, aerolysin that exported by Aeromonas hydrophila. This protein toxin forms channels on target cells membrane, disrupting normal activities and cause to destruction and death of them. Aerolysin toxic protein is secreted b...
متن کاملRibosomal protection proteins and their mechanism of tetracycline resistance.
Ribosomal protection represents an important tactic for promoting tetracycline resistance in both gram-positive and -negative species. Tet(O) and Tet(M) are the best studied of these determinants and were originally isolated from Campylobacter jejuni and Streptococcus spp., respectively, although both are widely distributed (10). These are the only two ribosomal protection proteins (RPPs) that ...
متن کاملMechanism of Tetracycline Resistance by Ribosomal Protection Protein Tet(O)
Tetracycline resistance protein Tet(O), which protects the bacterial ribosome from binding the antibiotic tetracycline, is a translational GTPase with significant similarity in both sequence and structure to the elongation factor EF-G. Here, we present an atomic model of the Tet(O)-bound 70S ribosome based on our cryo-electron microscopic reconstruction at 9.6-Å resolution. This atomic model al...
