Russia: The Long Road to Ratification. Internal Institution and Pressure Groups in the Kyoto Protocol’s Adoption Process

The Russian Federation played a crucial role in the ratification of the Kyoto Protocol. Indeed, after the US decision not to comply with the treaty, its ratification turned out to be indispensable for the Protocol to become legally binding. In early 2002, the Russian government decided to initiate the ratification process. However, notwithstanding this initial commitment, the country long hesitated to fulfil its promises, and for the last two years it sent numerous contradictory signals with respect to its position on climate policy. As a consequence, the factors that shape Russia’s behaviour in the context of climate negotiations received increasing attention. The main focus has been on the economic and international aspects motivating the Russian strategy. This paper attempts to complete this analysis by concentrating on a further feature that significantly contributed to Russia’s final decision, namely domestic forces. These factors have often been overlooked in the discussion of the Russian strategy. In order to fill this gap, this paper reconstructs the Russian ratification process, trying to identify the main domestic players and their role. Our findings provide various indications on the reasons of the recent developments in Russia, confirming the key role of the Russian President.Agreements, Climate, Incentives, Negotiations, Policy

A new approach in association study of single nucleotide polymorphism of genes for carcass and meat quality traits in commercial pigs

Six batches of four commercial hybrids of heavy pigs, reared for the production of Italian dry-cured hams, were identifiedfor having homogeneous feeding and farm conditions. For a total of 235 pigs, slaughtered in the same slaughterhouse,carcass traits and muscle composition were measured. The pigs were genotyped for single nucleotide polymorphisms(SNPs) of Na+, K+-ATPase subunit alpha 2 (ATPase, Na+/K+ transporting, alpha 2 (+) polypeptide; ATP1A2), cystatinB (CSTB), mitochondrial 2,4-dienoyl-CoA reductase 1 (DECR1), leptin (LEP; 3 SNPs), melanocortin receptor 4(MC4R), melanocortin receptor 5 (MC5R), sarcolipin (SLN) and titin (TTN) genes. All genes showed biallelic polymorphismsand the alleles were differently distributed between the six batches. Pigs were subsequentely clustered in “lean”and “fat” using either carcass traits (lean percentage, backfat thickness, loin muscle thickness, ham weight and hamcover fat thickness: 100 lean and 135 fat) or meat composition data (dry matter, protein, fat and ash of Biceps femorisand Vastus lateralis and pH after 24 hours: 126 lean and 109 fat). The association of gene polymorphisms with leanessand fatness of pigs was thus investigated using a logistic regression. ATP1A2, LEP (HinfI polymorphism) and MC4R,together with sex and ham weight were, included in the model to screen lean and fat pigs classified according to carcasstraits data, yielding a correct classification of 71%. For the lean and fat pigs classified according to muscle composition,sex, CSTB, DECR1, MC5R and LEP (AciI/TaqI polymorphisms) were included in the regression analysis, that yielded a66% of pigs correctly classified.These preliminary results may indicate that some of the selected candidate genes could be associated to production traitsand are worth of further investigations

Redefinition of the Mora Romagnola Pig Breed Herd Book Standard Based on DNA Markers Useful to Authenticate Its “Mono-Breed” Products: An Example of Sustainable Conservation of a Livestock Genetic Resource

Mora Romagnola is an autochthonous pig breed, raised in the north of Italy. Mono-breed pork products of this breed are part of important niche value chain that is intrinsically linked to the conservation of this local genetic resources that can only survive due to the premium price that these products can obtain on the market. However, the added value attracts fraudsters that unscrupulously sell mis-labelled Mora Romagnola products, causing consumer distrust that, in turn, undermines the conservation strategy of this breed. To monitor and better characterise this local breed, we phenotyped 826 Mora Romagnola pigs for three breed-specific traits. Then, we genotyped almost all living sows and boars registered to the Herd Book (n. = 357 animals) for polymorphisms in the MC1R and NR6A1 genes (affecting coat colour and vertebral number, respectively). The results were used to re-define the breed descriptors of the Mora Romagnala breed that included information on the allowed genotypes at these two genes. A few pigs that did not carry the allowed genotypes were excluded from its Herd Book. Finally, we evaluated the usefulness of these DNA markers to authenticate Mora Romagnola meat against meat derived from other 11 pig breeds and wild boars. To our knowledge, the Mora Romagnola Herd Book is one of the first examples that established a direct link between a genetic standard of a breed with the possibility to authenticate mono-breed products using DNA markers with the specific purpose to combat frauds and, indirectly, support the conservation of a livestock genetic resource

Wiskott–Aldrich syndrome protein (WASP) is a tumor suppressor in T cell lymphoma

In T lymphocytes, the Wiskott–Aldrich Syndrome protein (WASP) and WASP-interacting-protein (WIP) regulate T cell antigen receptor (TCR) signaling, but their role in lymphoma is largely unknown. Here we show that the expression of WASP and WIP is frequently low or absent in anaplastic large cell lymphoma (ALCL) compared to other T cell lymphomas. In anaplastic lymphoma kinase–positive (ALK+) ALCL, WASP and WIP expression is regulated by ALK oncogenic activity via its downstream mediators STAT3 and C/EBP-β. ALK+ lymphomas were accelerated in WASP- and WIP-deficient mice. In the absence of WASP, active GTP-bound CDC42 was increased and the genetic deletion of one CDC42 allele was sufficient to impair lymphoma growth. WASP-deficient lymphoma showed increased mitogen-activated protein kinase (MAPK) pathway activation that could be exploited as a therapeutic vulnerability. Our findings demonstrate that WASP and WIP are tumor suppressors in T cell lymphoma and suggest that MAP-kinase kinase (MEK) inhibitors combined with ALK inhibitors could achieve a more potent therapeutic effect in ALK+ ALCL.The work has been supported by grant no.
