Lessons from an eradication under multiple constraints of an island rat population of record density

open access: yesConservation Biology, EarlyView.
Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

The action of demineralized bovine bone matrix on bone neoformation in rats submitted to experimental alcoholism

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2013
The objective of this study was to evaluate whether demineralized bovine bone (Gen-ox®) alters bone neoformation in rats submitted to alcoholism. Forty male rats were separated into two groups of 20 rats and distributed as follows: Group E1, which ...

Island‐restricted reptiles are more threatened but less studied than their mainland counterparts

open access: yesConservation Science and Practice, EarlyView.
Reptiles are highly diverse on islands, yet there is no comprehensive overview of island‐restricted reptiles (IRRs) regarding their distribution, threat status, and research efforts. Our assessment revealed that despite IRRs comprising nearly a quarter of global reptile species and 30.8% being threatened, only 7.2% of the literature focuses on them ...

A fase estrogênica altera a resposta do osso e do metabolismo mineral de ratas com hipertireoidismo? Does the estrogenic phase modify the bone and mineral metabolism response in rats under hyperthyroidism?

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 2003
The effect of the estrogenic phase in the bone and in the mineral metabolism was studied in Wistar adult female rats kept under euthyroidism or hyperthyroidism for 60 days.

CEO‐employee pay ratio disclosure and dividend policy

open access: yesJournal of Financial Research, EarlyView.
Abstract We examine whether and how the magnitude of the CEO pay ratio affects dividend policy in the context of inequality‐averse investors. Our results demonstrate a positive association between the two and remain robust to endogeneity concerns. We find that the CEO pay ratios positively affect dividends irrespective of whether CEO compensation ...

Decreased nitric oxide levels in the hippocampus may play a role in learning and memory deficits in ovariectomized rats treated by a high dose of estradiol

open access: yesArquivos de Neuro-Psiquiatria, 2012
The effects of a high estradiol dose on memory and on nitric oxide metabolites in hippocampal tissues were investigated. Sham-Est and OVX-Est Groups were treated with 4 mg/kg of estradiol valerate for 12 weeks.

Mechanosensing in Dendritic Cells

open access: yesImmunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Since their discovery, dendritic cells have been recognized for their unusual capacity to sense and respond to physical stimuli within their environment. However, it took nearly two decades—and the advent of mechanobiology—to elucidate the underlying mechanisms and functional implications of this mechanical hypersensitivity. In this review, we

Population Genetics of an Endemic Species Mongoloniscus sinensis (Isopoda: Oniscidea) and Diversification Dynamics Across Northern China

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We explored the population genetics and demographic history of an isopod species endemic in temperate China on the basis of three mitochondrial genes. Three clusters were identified. The Midland group has the highest genetic diversity, and the greatest differentiation between the East and West groups was due to the geographical barrier caused by the ...
