Yolk metabolomics reveals candidate compounds associated with egg specific density and hatchability in white layer breeder hens

Thomas AC. Calil, Bruno Serpa Vieira, Simone Sommerfeld, Arlene B. dos S. Nossol et autres

The present study aimed to evaluate the influence of egg geometry, weight loss, and specific density (SD) on hatchability in older white layer breeder hens. In addition, based on the positive correlation observed between fertility and egg SD, we hypothesized that the …

Ligand Rigidity and π-Surface Modulate Biomolecular Interactions and Cytotoxicity in Ru(II) Polypyridyl Complexes

Patrícia Alves de Matos, Marcos Eduardo G. Carmo, André L.A. Parussulo, Clara Maria Faria Silva et autres

The complexes cis-[Ru(dmbpy)2Cl(bpy)](PF6) (Rubpy) and cis-[Ru(dmbpy)2Cl(bpe)](PF6) (Rubpe) (dmbpy = 4,4′-Dimethyl-2,2′-dipyridyl, bpy= 4,4′-dipyridyl and bpe = 1,2-bis(4-pyridyl)ethane) were synthesized and spectroelectrochemically characterized. Both Ru(II) complexes exhibited absorption bands assigned to intraligand and metal-to-ligand charge transfer (MLCT) transitions, and their spectral stability in PBS …
