Journal of Applied Toxicology, EarlyView.ABSTRACT The N‐acylhydrazone scaffold is recognized as a privileged structure for the design of bioactive substances with increasing applications in medicinal chemistry research. Ensuring the safety of newly developed molecules is a critical step for both human health and environmental protection. Accordingly, this study aimed to evaluate the cytotoxic

A Comparison of the Composition of New and Evolved Comets
, 1976 The intensity ratio of the continuum to the molecular emissions was estimated in the spectra of eight-five comets. Four conclusions are drawn: (1) There is no readily apparent difference in continuum to emission intensity ratio between new and more ...

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 ...

Comets and their origin: the tools to decipher a comet
, 2014 Divided into two parts, the first four chapters of Comets and their Origin refer to comets and their formation in general, describing cometary missions, comet remote observations, astrochemistry, artificial comets, and the chirality phenomenon.The second

Spectrophotometry and structural analysis of 5 comets
, 2002 We discuss the morphology and spectrophotometry of 5 comets visible in August, 2001. We decompose comae into coma profiles and azimuthally renormalized images, in which general and local features are quantitatively comparable. Comet 19P/Borrelly showed a

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

Evolution of Halley-type Comets and Meteoroid Streams
, 2014 The overall objective of the thesis is to understand the long term orbital dynamics of comets and meteoroid streams. The initial idea focused mainly on detailed analysis of Jovian resonances in Orionids and Leonids.

Nail Disorders in Systemic Conditions
JEADV Clinical Practice, EarlyView.ABSTRACT Nail findings in children can be indicative of an underlying systemic disease. Many of these findings are seen in multiple entities and are not specific to one disease. The importance of specifically examining for these nail changes cannot be overstated.

Periodontology 2000, EarlyView., 2023 Abstract Periodontitis is a long‐term condition affecting up to half of the population globally and causing significant impacts on life quality. Successful management depends on taking life‐long ownership of the condition by those affected. There is a wealth of research to inform on management options. However, most of the research has been designed by

Herschel/SPIRE observations of water production rates and ortho-to-para ratios in comets [PDF]
, 2017 This paper presents Herschel/SPIRE (Spectral and Photometric Imaging Receiver) spectroscopic observations of several fundamental rotational ortho- and para-water transitions seen in three Jupiter-family comets and one Oort-cloud comet. Radiative transfer
