Journal of Applied Toxicology, EarlyView.ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...

The cometary and asteroidal origins of meteors [PDF]
A quantitative examination of the gravitational and nongravitational changes of orbits shows that for larger interplanetary bodies the perturbations by Jupiter strongly predominate over all other effects, which include perturbations by other planets ...

Dust and gas emission from cometary nuclei: the case of comet 67P/Churyumov-Gerasimenko
, 2018 Comets display with decreasing solar distance an increased emission of gas and dust particles, leading to the formation of the coma and tail. Spacecraft missions provide insight in the temporal and spatial variations of the dust and gas sources located ...

Journal of Applied Toxicology, EarlyView.ABSTRACT Bisphenol A (BPA), a ubiquitous environmental endocrine disruptor, has been implicated in carcinogenesis; however, its effects on thyroid cells remain unclear. This study investigated BPA‐induced cytotoxicity and genotoxicity in thyroid cell lines, including normal follicular (Nthy‐ori 3‐1), papillary carcinoma (TPC‐1 and BCPAP) and anaplastic

Comet 17P/Holmes in Outburst: The Near Infrared Spectrum
, 2009 Jupiter family comet 17P/Holmes underwent a remarkable outburst on UT 2007 Oct. 24, in which the integrated brightness abruptly increased by about a factor of a million.We obtained near infrared (0.8 - 4.2 micron) spectra of 17P/Holmes on UT 2007 Oct. 27,

Journal of Applied Toxicology, EarlyView.ABSTRACT Tartrazine is a synthetic azo dye widely used in food, pharmaceutical, and cosmetic products, resulting in extensive human exposure, while its toxicity and that of its primary metabolite, sulfanilic acid, remain controversial. Considering the reported association of tartrazine with hypersensitivity and allergic‐like reactions, human bronchial ...
