First Assessment of Genetic Damage in the Speckled Cockroach (Nauphoeta cinerea) After Consumption of Lettuce (Lactuca sativa) Cultivated and Commercialized in Northeastern, Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study reports, for the first time, the use of the speckled cockroach Nauphoeta cinerea as a promising bioindicator for genotoxic monitoring. It was validated through control groups (both positive and negative) in addition to testing lettuce (Lactuca sativa ) samples from public street markets consumed by N. cinerea specimens in Pernambuco,

Abstract 4862: Histone deacetylase inhibition induces DNA damage, slows down replication forks and activates dormant origins

open access: yes, 2010
Histone acetylation is often altered in cancers and histone deacetylases inhibitors (HDACi) are actively pursued as anti-cancer agents. SAHA (suberoylanilide hydroxamic acid) is the first HDACi approved for clinical use.

Cytogenotoxic Effects of Fluopyram in Allium cepa Root Cells Involving Microtubule Disruption

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Fluopyram is a next‐generation fungicide widely used in agriculture; however, its persistence in soils and mobility toward aquatic systems have raised concerns regarding potential ecotoxicological risks. This study evaluated the cytogenotoxic effects of a commercial fluopyram‐based pesticide formulation on Allium cepa root meristem cells ...

How weather got its words: a history of meteorological English – Part 2: the scientific age and beyond

open access: yesWeather, EarlyView.
The English language is a gargantuan, gluttonous beast. It has become extraordinary in its powers of assimilation – such that we rarely consider the origins of the words we use. In this paper, we will shed light on these origins, including the Pontic–Caspian steppe, the British Empire and, of course, a TV show.
