In response to the US EPA HPV Challenge Program, this study was conducted to: (1) evaluate the relationship between PAC content and the developmental toxicity of high-boiling petroleum substances (HBPS) and (2) develop mathematical models to predict the developmental toxicity of similar untested substances based on their aromatic ring class (ARC) profiles. For this investigation, 68 development...
Nu-3 [butyl-phosphate-5'-thymidine-3'-phosphate-butyl] is a modified nucleotide that has been shown to have antimicrobial activity against a range of bacteria including Pseudomonas aeruginosa. However, data on the toxicological profile of Nu-3 are still lacking. In the present study, the toxicity of Nu-3 was evaluated by the following studies: acute oral toxicity, dermal and mucous membrane irr...
wastewater production is increasing every year. the variety of contaminants necessitates the application of effective and advanced treatment methods. among the materials that are predominantly used for wastewater treatment are carbon nanotubes. exposure to the residuals of carbon nanotubes after wastewater treatment through drinking, inhalation, and dermal contact during regular indoor activit...
A health risk-based surface contamination cleanup standard (SCS) for beryllium (BE) was developed to facilitate the safe transfer of property (equipment and buildings) previously used in BE-related processes. Previous SCSs for BE were primarily based on Department of Energy (DOE) housekeeping criteria rather than health risks. Quantitative health risk assessment methods were used to develop an ...
Hypoxia, caused by disrupted vasculature and peripheral vasculopathies, is a key factor that limits dermal wound healing. Factors that can increase oxygen delivery to the regional tissue, such as supplemental oxygen, warmth, and sympathetic blockade, can accelerate healing. Clinical experience with adjunctive hyperbaric oxygen therapy (HBOT) in the treatment of chronic wounds have shown that wo...
A 13-week dermal repeat-dose toxicity study was conducted with hydrodesulfurized (HDS) kerosene, a test material that also met the commercial specifications for aviation turbine fuel (jet A). The objectives were to assess the potential for target organ toxicity and neurotoxicity. The HDS kerosene was applied to the shaved backs of Sprague-Dawley CD rats, 12/sex/group, 6 h/d, 5 d/wk in doses of ...
Permethrin and Cypermethrin are synthetic pyrethroids, belonging to a group of insecticides with low mammalian toxicity and high insecticidal activity. The present study evaluated sub-acute toxicity of dermally administrated permethrin and cypermethrin in mice. Behavioral examination included assessments of lethality, weight gain, grooming, analgesymetry, anxiety, grasping, motor activity, and ...
conclusions based on the results of the current study, it was concluded that aloe vera, licorice and mint extracts had synergistic effects on the viability of dermal fibroblasts; in addition, the combination of aloe vera and licorice with either henna or myrtle, and aloe vera and mint with either cedar or ginger resulted in synergistic effects on viability of dermal fibroblasts. the third categ...
