QSAR models are frequently used to investigate and predict the toxicological effects of chemicals. Building QSAR models of the eye irritation potential of cationic surfactants is difficult, as the mechanism of action of these surfactants is still not fully understood. This report describes a data driven QSAR model to predict Maximum Average Scores (MAS in accordance to Draize) for cationic surf...
The treatment of corneal abrasion currently involves the topical administration antibiotics, with moxifloxacin HCl (0.5% w/v) eye drops being one most widely used treatments. Our previous work (Tawfik et al., 2020) involved development coaxial poly-lactic-co-glycolic acid (PLGA) and polyvinylpyrrolidone (PVP) nanofibers loaded antibiotic anti-scarring agent pirfenidone in core shell respectivel...
The immunohistochemical characterisation of an SV40-immortalised human corneal epithelial cell line.
Alternatives to the Draize rabbit eye irritation test are currently being investigated. Because of morphological and biochemical differences between the rabbit and the human eye, continuous human cell lines have been proposed for use in ocular toxicology studies. Single cell-type monolayer cultures in culture medium have been used extensively in ocular toxicology. In the present study, an SV40-...
Alcohol-based hand rubs are widely used for infection control in clinical practice. However, it is known that frequent use of the alcohol-based hand rubs may cause skin irritation. To predict the skin irritation in human, animal experiments are quite useful. Especially, the Draize Test using rabbits is suitable for this purpose because their skin is highly sensitive. On the other hand, the deve...
BACKGROUND Dust exposure is a well-known occupational hazard for terrestrial workers and astronauts alike and will continue to be a concern as humankind pursues exploration and habitation of objects beyond Earth. Humankind's limited exploration experience with the Apollo Program indicates that exposure to dust will be unavoidable. Therefore, NASA must assess potential toxicity and recommend app...
The HET-CAM (Hen's Egg Test-Chorioallantoic Membrane) assay is an in vitro alternative to the in vivo Draize Rabbit Eye test that mimics vascular changes in the chorioallantoic membrane. This qualitative method assesses the irritancy potential of chemicals. The CAM responds to injury with an inflammatory process similar to that in the rabbit eye's conjunctival tissue. Regarding topical toxicity...
Rosacea is the most common inflammatory skin disease. It is characterized by erythema, inflammatory papules and pustules, visible blood vessels, and telangiectasia. The current treatment has limitations and unsatisfactory results. Pioglitazone (PGZ) is an agonist of peroxisome proliferator-activated receptors (PPARs), a nuclear receptor that regulates important cellular functions, including inf...
Fingolimod (FTY720), a novel class of sphingosine 1-phosphate receptor modulators, has received special interest among ophthalmologists, particularly given that oral administration of FTY720 has proven to effectively treat corneal graft rejection in animal models. However, no studies have examined the performance of FTY720 as an ophthalmic solution in reducing corneal rejection in high-risk cor...
