Quantification of residual enrofloxacin and ciprofloxacin in feathers of broiler chickens by high-performance liquid chromatography-fluorescence after oral administration of the drugs

open access: yesJournal of Advanced Pharmaceutical Technology & Research, 2016
Enrofloxacin (ENR) and ciprofloxacin (CIP) are drugs used in poultry feeding. In general, feathers that are incorporated in the food chain as a protein source for animal feed, have residues of these drugs. In order to study the pharmacokinetic of ENR/CIP

Birds of many feathers? Examining perceptions among US birders following the American Ornithological Society's eponymous renaming decision

open access: yesPeople and Nature, EarlyView.
Abstract In 2023, the American Ornithological Society announced it will phase out the English eponymous (honorific) names of 152 bird species in the United States and Canada, some of which are named after historical figures with racist, genocidal, or otherwise violent histories that serve as reminders of ornithology's exclusive origins.

Carbonized polymer dots with aqueous‐stable room‐temperature phosphorescence: Mechanism, matrix engineering, and application

open access: yesResponsive Materials, EarlyView.
This review focuses on inorganic and organic matrices that enable aqueous‐stable room‐temperature phosphorescence (RTP) in carbonized polymer dots (CPDs). It explains the underlying RTP mechanisms, highlights how matrix engineering provides spatial confinement and bonding interactions to stabilize triplet excitons in water, and demonstrates key ...

Environmental Contaminant Accumulation in Freshwater Turtles Inhabiting Three Rivers of the Permian Basin, New Mexico, USA

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Freshwater turtles are valuable sentinels of aquatic systems due to their long lifespans and resilience in environments impacted by contaminants. The Permian Basin, dominated by the oil and gas sector, spans western Texas and southeastern New Mexico, USA, including the Pecos River and its tributaries, the Delaware and Black Rivers.

Embryotoxic Effects of Monosodium Methyl Arsenate (MSMA) on Gallus gallus: Morphological and Morphometric Evidence of Developmental Disruptions

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Anthropogenic activities and the large volume of compounds released into the environment are sources of contamination for plants, animals, and humans. The herbicide monosodium methyl arsenate (MSMA) ranks among the best‐selling agricultural pesticides in Brazil.

Diet sources of the endangered Attwater's prairie‐chicken in Texas: evidence from δ13C, δ15N, and Bayesian mixing models

open access: yesEcosphere, 2020
The Attwater's prairie‐chicken (APC; Tympanuchus cupido attwateri) was listed as an endangered species in 1967, and since then multiple studies have addressed ecological and human factors that may have limited their population recovery. In this study, we
