Identification and Quantification of Volatile Organic Compounds and Bioaerosols in the Conservation Processes of Guanche Mummies

Archaeometry, EarlyView.
ABSTRACT The Guanche mummies, ancient inhabitants of the Canary Islands, represent a significant part of the historical heritage preserved at the Museum of Nature and Archaeology (MUNA) in Tenerife, Spain. These mummies, subjected to artificial conservation practices, are of great interest to conservators seeking to understand their mummification ...

Inhibitory Effect of Natural Phenolic Compounds on Aspergillus parasiticus Growth

Journal of Chemistry, 2015
Considering the impact of Aspergillus species on crops, it appears to be highly desirable to apply strategies to prevent their growth, as well as to eliminate or reduce their presence in food products. For this reason, the aims of this investigation were

Toxic Mixtures in Time—The Sequence Makes the Poison [PDF]

, 2017
“The dose makes the poison”. This principle assumes that once a chemical is cleared out of the organism (toxicokinetic recovery), it no longer has any effect. However, it overlooks the other process of re-establishing homeostasis, toxicodynamic recovery,

Solid Shampoo Is Mostly Not Preserved, in Contrast to Liquid Shampoos Used in Hairdressing—A Market Survey in Four European Countries

Contact Dermatitis, EarlyView.
Most solid shampoos (68.6%) did not contain preservatives according to Annex V of the EU Cosmetics Regulation (EC 1223/2009), while all liquid shampoos did. The number of preservatives used was significantly greater in liquid shampoos. ABSTRACT Background Hairdressers are frequently exposed to shampoos, both from neat liquid products and dilutions ...

Molecular bases of insect odorant receptor function: specificity and evolution

Biological Reviews, Volume 101, Issue 2, Page 1036-1049, April 2026.
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

On Viscous Flow in Glass-Forming Organic Liquids

Molecules, 2020
The two-exponential Sheffield equation of viscosity η(T) = A1·T·[1 + A2·exp(Hm/RT)]·[1 + C·exp(Hd/RT)], where A1, A2, Hm, C, and Hm are material-specific constants, is used to analyze the viscous flows of two glass-forming organic materials—salol and α ...

Variation in Microbiome Composition and Faecal Metabolites Are Associated With Differential Susceptibility to DSS‐Induced Colitis

Immunology, Volume 177, Issue 4, Page 766-783, April 2026.
C57BL/6 mice from Charles River Laboratories (CR) have enhanced mucosal immune action relative to C57BL/6 mice from Jackson Laboratories (JAX). CR mice are more susceptible to severe DSS‐induced colitis than JAX mice. Co‐housing transfers colitis susceptibility from CR mice to JAX mice.

Hepatotoxicity of dinitro-O-cresol in rats (Rattus norvegicus)

Acta veterinaria, 2007
In this study we investigated the hepatotoxic effect of DNOC in rats, using biochemical serum parameters as indicators of liver disease. Experimental groups were injected intraperitoneally with 2.8 mg/kg DNOC. While an increase was determined in LDH activities for all periods, an increase was determined for urea values only up to 16 hours.
