The Role of Ammonia in the Distribution of Volatiles in the Primordial Hydrosphere of Europa
The Planetary Science JournalThe presence of a hydrosphere on Europa raises questions about its habitability, and studies of its volatile inventory can provide insight into its formation process. Different scenarios suggest that Europa's volatiles could be derived from cometary ices

Journal of Applied Toxicology, EarlyView.ABSTRACT The present study aimed to quantify pesticide residues in environmental matrices and plasma and to evaluate their potential effects on oxidative stress and DNA damage in rural populations of Santa Fe province. Soil and rainwater samples were collected, and biological samples and semistructured surveys were obtained from volunteers in three ...

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

On the Problem of the Origin of Comets [PDF]
Symposium - International Astronomical Union, 1972 The various hypotheses on the origin of comets are surveyed, with particular reference to the phenomenon of comet-streaming, as revealed by statistical analysis of the directions of the perihelia of cometary orbits. The difficulties of reconciling comet-streaming with any of the hypotheses of cometary origin is pointed out. It is shown that in the case

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 ...

International Astronomical Union Colloquium, 1977 Empirical data are confronted with different hypotheses on the origin of comets. The hypotheses are classified into three categories: 1) Comets were condensed from the solar nebula and ejected later into the Oort’s cloud. 2) Comets were condensed in situ, more or less recently, on their present trajectories; 3) Reversing the arrow of time in the ...

Journal of Applied Toxicology, EarlyView.ABSTRACT Children, as a particularly vulnerable group, are more susceptible to these mutagens due to their developing immune systems, higher physiological vulnerability, and increased exposure through behaviors like outdoor play and hand‐to‐mouth activities. This review aims to investigate the relationship between these environmental exposures, genetic

Anti‐inflammatory and cytotoxic properties of kānuka (Kunzea ericoides) subcritical water extract
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND Kānuka (Kunzea ericoides) is a medicinal plant native to New Zealand with numerous therapeutic benefits due to its rich bioactive profile. Although several in vitro studies have shown promising anti‐inflammatory activity, substantial evidence elucidating its underlying inflammatory regulatory mechanism and evaluating its cytotoxic ...
