Corticosterone mediates the condition-dependent component of melanin-based coloration
TLDR
The finding that corticosterone-implanted nestlings produced feathers with less phaeomelanic coloration than placebo-implanting nestlings is consistent with the hypothesis that the environment-mediated reduction in the degree of melanism is, at least in part, caused by a rise in cortic testosterone.

Determination of insoluble avian eggshell matrix proteins
TLDR
This work studied EDTA-insoluble proteins by gradual decalcification of eggshell with EDTA and identified for the first time collagens I and III in the eggshell matrix, and Kunitz-like protease inhibitor as a major shell matrix protein. Expand
Molluscan shell evolution with review of shell calcification hypothesis.
TLDR
This study reconsiders the above three components of chitin, silk fibroin protein, and acidic macromolecules with adding some biochemical data of aculiferans, and suggested importance of comparison between acuriferans and conchiferans. Expand
Proteins of Insoluble Matrix of Avian (Gallus Gallus) Eggshell
TLDR
The protein composition of the insoluble avian eggshell matrix was studied using enzymatic cleavage followed by a high-performance liquid chromatography–mass spectrometry method and the influence of various enzymes on the protein splitting also was studied. Expand
Egg pigmentation reflects female and egg quality in the spotless starling Sturnus unicolor
TLDR
The results provide evidence that eggshell pigmentation in the spotless starling is related to female and egg quality as shown by the yolk testosterone levels, but the lack of relation between egg colour and female condition and eggquality do not provide evidence to support the signalling function of egg colouration. Expand
Direct linkage of mitochondrial genome variation to risk factors for type 2 diabetes in conplastic strains.
TLDR
It is shown that conplastic strains of rats with identical nuclear genomes but divergent mitochondrial genomes that encode amino acid differences in proteins of oxidative phosphorylation exhibit differences in major metabolic risk factors for type 2 diabetes. Expand
AMP-activated Protein Kinase α2 Subunit Is Required for the Preservation of Hepatic Insulin Sensitivity by n-3 Polyunsaturated Fatty Acids
TLDR
It is shown that n-3 LC-PUFAs prevent hepatic insulin resistance in an AMPKα2-dependent manner and support the role of adiponectin and hepatic diacylglycerols in the regulation of insulin sensitivity. Expand
Insoluble eggshell matrix proteins – their peptide mapping and partial characterization by capillary electrophoresis and high‐performance liquid chromatography
TLDR
It was concluded that there are at least three different insoluble protein/peptide layers in the avian eggshell (cuticle, palisade, and mammillary layer). Expand
Condition-dependent strategies of eggshell pigmentation: an experimental study of Japanese quail (Coturnix coturnix japonica)
TLDR
It is predicted that females maintain eggshell colour to limit visible changes that could be detected by predators and thereby conceal their eggs, although this work has yet to be conducted and further experimental work on egg camouflage under different environmental conditions is suggested. Expand
Modifications of degradation-resistant soil organic matter by soil saprobic microfungi
Modifications of humic (HA) and fulvic (FA) acids in their solutions and in sterile soil by microfungal species and two well-known HA degraders were studied by measurement of total oxidizable carbonExpand
