A commercially reared domesticated turkey (Meleagris gallopavo) was purchased from a local market and sections of tissue representing leg, thigh, and breast were harvested and processed for analysis of the lipids and proteins present. Leg and thigh tissue was enriched in mitochondrial proteins whereas the breast tissue was enriched in glycolytic enzymes as well as the cytosolic and mitochondrial forms of glycerol-3-phosphate dehydrogenase. A potential marker for breast tissue muscle formation and/or function was also identified. The tissues could clearly be separated based upon their lipid profiles with little differences in cardiolipin levels suggesting that mitochondrial surface areas may be similar across the tissues. The most significant differences in the lipids were found to be higher levels of oxidized lipids in thigh meat. This work provides the first untargeted proteome and lipidome datasets for the domesticated turkey. The proteome dataset is accessible from ProteomeXchange Consortium via the PRIDE partner repository with the identifier PXD008207.

Cross-species amplification of 520 chicken microsatellite markers was tested by polymerase chain reaction with genomic DNA of the turkey (Meleagris gallopavo). Each primer pair was tested at six different combinations of annealing temperature and MgCl2 concentration. A total of 280 (54%) of the primer pairs produced amplification products. The majority of these products were similar, if not identical in size to those expected based on the fragment sizes of the corresponding chicken loci. Structure of the dinucleotide repeat and flanking sequences was examined for 13 turkey fragments (amplified with chicken primers) and 5 chicken fragments (amplified with turkey primers). Sequence analysis found a wide array of mutations between species in addition to differences in repeat length. To estimate the usefulness of the amplified loci for genetic mapping in the turkey, allelic polymorphism was determined for 57 of the 280 amplified loci. A total of 20 of 57 markers (35%) were polymorphic with an average of 1.4 alleles per locus. The results of this study suggest that approximately 20% of the chicken microsatellite markers will be useful for mapping the turkey genome.Key words: microsatellite, chicken, turkey, Meleagris gallopavo.

In this paper, we investigated the oxidative profile of breast tumors in comparison with their normal adjacent breast tissue. Our study indicates that breast tumors present enhanced oxidative/nitrosative stress, with concomitant augmented antioxidant capacity when compared to the adjacent normal breast. These data indicate that breast cancers may be responsible for the induction of a prooxidant environment in the mammary gland, in association with enhanced TNF-αand nitric oxide.

The comparative analysis of the main approaches to the reasons for the home bias is explored. The main factors of home bias are identified. The reasons for the existence of home bias are determined on the basis of systematization of the existing discourse. The main stages of the evolution of approaches to determining the reasons for home bias are identified. It was found that the most promising approach is the behaviourist approach, as well as the institutional approach and the transaction costs approach. The historical and current dynamics of the home bias in the investment portfolios of different countries is studied. A comparative analysis of the home bias for different groups of countries according to their level of economic development is carried out. It was found that developed countries have the lowest share of local market assets in the portfolio. The evolution of approaches to the home bias has been studied. The main scientific publications on the issue of home bias in the historical perspective are analysed and systematized. The main quantitative dimensions of the expression of home bias are highlighted. The main forms of quantitative expression of home bias, which received relative expression in the form of indices, are studied. The qualitative and quantitative composition of modern investment portfolios of the countries with the largest shares in the world market capitalization is studied and analysed. It has been found that there are countries with traditionally low and high levels of international diversification, such as China and Luxembourg, respectively.

AbstractCardiolipin (CL) is a mitochondrial inner membrane glycerophospholipid that associates with mitochondrial proteins to promote their activities and to facilitate protein complex and super-complex formation. Loss of CL leads to destabilized respiratory complexes and mitochondrial dysfunction. The role of CL in an organism lacking a conventional electron transport chain (ETC) has not been elucidated so far. We now report that in Trypanosoma brucei bloodstream forms, in which the ETC is truncated and composed of alternative oxidase and glycerol-3-phosphate dehydrogenase, and the mitochondrial membrane potential is generated by the hydrolytic action of the FoF1-ATP synthase, the inducible depletion of cardiolipin synthase (TbCls) is essential for parasite survival. Loss of TbCls and CL caused a rapid drop in ATP levels and a decline in the mitochondrial membrane potential. Unbiased proteomic analyses revealed a reduction in the levels of many mitochondrial proteins, most notably of FoF1-ATP synthase subunits and of the alternative oxidase, resulting in a strong decline of glycerol-3-phosphate-stimulated oxygen consumption. Interestingly, the changes in cellular respiration preceded the observed decrease in FoF1-ATPase stability, suggesting that the truncated ETC is the first pathway responding to the decline in CL. In addition, proteomic and metabolomic analyses revealed that select proteins and pathways involved in glucose and amino acid transport and metabolism are up-regulated during CL depletion, possibly as a stress response to restore cellular ATP levels.
