Metformin is a biguanide derivative which is widely prescribed as an oral drug for diabetes mellitus type 2. This old molecule has recently received a new attention because of its therapeutic properties in oncology, that seem to be independent of its action on glycemia homeostasis. The reappraisal of its pharmacological effects was supported by delineation of signaling pathways and more recentl...
The high-pressure polymorphs of CuI have attracted much attention due to the somewhat contradictory identification of their structures by means of x-ray diffraction measurements and theoretical calculations. In this paper, we report the results of a theoretical investigation of polymorphs of CuI including zinc-blende, rhombohedral, tetragonal, rocksalt and orthorhombic phases. We find that CuI...
We investigated the antiviral activity of nanosized copper(I) iodide (CuI) particles having an average size of 160 nm. CuI particles showed aqueous stability and generated hydroxyl radicals, which were probably derived from monovalent copper (Cu(+)). We confirmed that CuI particles showed antiviral activity against an influenza A virus of swine origin (pandemic [H1N1] 2009) by plaque titration ...
The objective of this study was to evaluate the effect of particle size of a dietary Ca source on egg production and eggshell quality when added to hens’ diets that have different levels of calcium. The experiment was carried out on 216 ISA Brown hens (25 to 70 weeks of age), allocated to 9 groups of 12 replicates (cages), with two birds in each cage. A 3 × 3 factorial arrangement was used, wit...
Avian eggshells are variedly coloured, yet only two pigments, biliverdin and protoporphyrin IX, are known to contribute to the dramatic diversity of their colours. By contrast, the contributions of structural or other chemical components of the eggshell are poorly understood. For example, unpigmented eggshells, which appear white to the human eye, vary in their ultraviolet (UV) reflectance, whi...
Birds' eggshells are renowned for their striking colours and varied patterns. Although often considered exceptionally diverse, we report that avian eggshell coloration, sampled here across the full phylogenetic diversity of birds, occupies only 0.08-0.10% of the avian perceivable colour space. The concentrations of the two known tetrapyrrole eggshell pigments (protoporphyrin and biliverdin) are...

Abbasali Gheisari*, Peyman Ghayor Department of Animal Science, Isfahan Research Center for Agriculture and Natural Resources, Isfahan,Iran * Corresponding author E-mail: [email protected] Received: 15 August 2013 Accepted: 21 November 2013 Abstract This experiment was conducted to investigate the effect of feeding 5 experimental diets containing 0, 5, 10, 15 and 20%...
This study reports the simple process to synthesis of CuO/CuI nanocomposite in a non-aqueous solution. In the conducted experiments CuI and Dimethyl Sulfoxide (DMSO) were used as the precursors. Moreover, DMSO had role of solvent and ligand simultaneously. In experiments the effects of oleic acid as the particles size modifier, temperature and concentration were investigated. Crystalline struct...
1. Environmental factors such as temperature, humidity and partial oxygen pressure can affect avian eggshell structure because gas exchange across the shell must allow sufficient water loss while preventing dehydration of the embryo. Studies of species with known chronology of colonization of novel environments provide a powerful insight into the relative importance of ecological factors shapin...
