The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.

Persistent expression of BMP-4 in embryonic chick adrenal cortical cells and its role in chromaffin cell development [PDF]

open access: yes, 2008
Background: Adrenal chromaffin cells and sympathetic neurons both originate from the neural crest, yet signals that trigger chromaffin development remain elusive.

Experimental Evidence for Mobilization of Mercury From the Eggshell by the Developing Embryo in an Avian Model Organism

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Of the many pollutants wildlife is exposed to, mercury ranks among the most toxic. In birds, mercury does not only accumulate within generations, but also is transferred across generations via maternal offloading in eggs, with higher mercury concentrations found in shells of unhatched eggs.

Electroporation of Embryonic Chick Eyes

open access: yesBio-Protocol, 2015
The chick embryo has prevailed as one of the major models to study developmental biology, cell biology and regeneration. From all the anatomical features of the chick embryo, the eye is one of the most studied.

Expression and regulation of Cek-8, a cell to cell signalling receptor in developing chick limb buds [PDF]

open access: yes, 1996
The Eph-related receptor tyrosine kinase gene, Cek-8, is expressed in mesenchyme at the tip of chick limb buds, with high levels of transcripts posteriorly and apically but fading out anteriorly.

Flap Anatomies and Victorian Veils: Penetrating the Female Reproductive Interior

open access: yesGender &History, EarlyView.
ABSTRACT This article examines the reappearance in the early nineteenth century of anatomical flapbooks in the context of obstetrical education in Britain, America and France. It asks why liftable paper flaps were reintroduced at this time after their disappearance from medical atlases in the eighteenth century.

Breeding Dispersal of Baltic Dunlins Is Not an Adaptive Response to Unpredictable Nest Flooding

open access: yesAnimal Conservation, EarlyView.
Flood‐related nest losses of the Baltic dunlin (Calidris alpina schinzii) have drastically increased over the past two decades. Using 20 years of reproductive data from 184 individuals, we found that between‐year and within‐site dispersal tended to increase following nest failure in males.

The c‐Src inhibitor eCF506 diminishes opioid tolerance and reduces β‐arrestin2 recruitment

open access: yesBritish Journal of Pharmacology, EarlyView.
Morphine activation of μ receptors causes tolerance through c‐Src activation and β‐arrestin2 recruitment. c‐Src inhibition or degradation reduces β‐arrestin2 recruitment, μ receptor endocytosis, while causing receptor upregulation, all likely contributing to reduced morphine tolerance.
