Greater TTIP Ambition in Chemicals: Why and how. CEPS Special Report, 28 July 2015. Paper No. 10 in the CEPS-CTR project ‘TTIP in the Balance’ and CEPS Special Report No. 114/July 2015.

To date, the negotiations over chemicals in the Translatlantic Trade and Investment Partnership (TTIP) have not shown sufficient ambition. The talks have focused too much on the differences in the two ‘systems’, rather than on the actual levels of health and environmental protection for substances regulated by both the US and the EU. Given the accomplishments within the OECD and the UN Globally Harmonised System of Classification and Labelling of Chemicals (GHS), the question is whether TTIP can be any more ambitious in the area of chemicals? We find that there is no detailed or systematic knowledge about how the two levels of protection in chemicals compare, although caricatures and stereotypes abound. This is partly due to an obsessive focus on a single US federal law, the Toxic Subtances Control Act (TSCA), whereas in practice US protection depends on many statutes and regulations, as well as on voluntary withdrawals (under pressure from the Environmental Protection Agency) and severe common law liability. This paper makes the economic case for firmly addressing the regulatory barriers, discusses the EU’s proposals, finds that the European Parliament’s Resolution on TTIP of July 2015 lacks a rationale (for chemicals), argues that both TSCA and REACH ought to be improved (based on ‘better regulation’), discusses the link with a global regime, advocates significant improvement of market access where equivalence of health and environmental objectives is agreed and, finally, proposes to lower the costs for companies selling in both markets by allowing them to opt into the other party’s more stringent rules, thereby avoiding duplication while racing-to-the-top. The ‘living agreement’ on chemicals ought to be led by a new TTIP institution authorised to establish the level of health and environmental protection on both sides of the Atlantic for substances regulated on both sides. These findings will lay the foundation for a highly beneficial lowering of trading costs without in any way affecting the level of protection. Indeed, this is exactly what TTIP is, or should be, all about.This paper is the 10th in a series produced in the context of the “TTIP in the Balance” project, jointly organised by CEPS and the Center for Transatlantic Relations (CTR) in Washington, D.C.

Efeitos de um programa de treino cognitivo e das técnicas de higiene do sono para as funções executivas e para a qualidade de sono em idosos saudáveis

The aging process causes changes in the elderly’s sleep/awake standard impairing their cognitive abilities, particularly executive functioning, which already suffers loss by aging. The literature suggests that executive function and preserved sleep quality are key to maintaining good quality of life and independence of older people, requiring interventions to minimize the impact of losses incurred by the aging process. This study evaluated the effect of a cognitive training program and sleep hygiene techniques for executive functions and sleep quality in healthy older people. The participants were 41 healthy older adults, of both sexes, who were randomly divided into four groups: control group [GC], cognitive training group [GTC], sleep hygiene group [GHS] and training group + hygiene [GTH]. The research was developed in three stages: 1st - initial assessment of cognition and sleep; 2nd - specific intervention to each group; 3rd - post-intervention revaluation. The results showed that GTC had significant improvements in cognitive tasks flexibility, planning, verbal fluency and some aspects of episodic memory, besides gains in sleep quality and decrease on daytime hypersomnolence. The GHS improved sleep quality and daytime sleepiness as well and had significant improvements in insights capacity, planning, attention and in all evaluated aspects of episodic memory. The GTH had significant gains in cognitive flexibility, problem solving, verbal fluency, attention and episodic memory. The CG showed significant worsening in excessive daytime sleepiness in capacity planning. Thus, we conclude that cognitive training interventions and sleep hygiene strategies are useful in improving cognitive performance and quality of healthy elderly sleep.

Comparative Analysis of Genus Bifidobacterium: Insight into its Host Adaptation

Bifidobacteria is amongst one of the health promoting bacteria. The role of this important probiotic genera can be elucidated by understanding its genome. Comparative analysis of the whole genus of these bacteria can reveal their adaptation to a diverse host range. This study comprises of four research projects. In the first study, a reference library for genus Bifidobacterium was prepared. The core genes in each genus were selected based on a newly proposed statistical definition of core genome. Comparative analysis of Bifidobacterium with another probiotic genus Lactobacillus revealed the metabolic characteristics of genus Bifidobacterium. The second study investigated the immunomodulatory role of a B. bifidum strain TMC3115. The analysis of TMC3115 provided insights into its extracellular structures which might have their role in host interaction and immunomodulation. The study highlighted the variability among these genomes just not on species level but also on strain level in terms of host interaction. The last two studies aim to inspect the relationship between bifidobacteria and its host diet. Bifidobacteria, are both host- and niche-specific. Such adaptation of bifidobacterial species is considered relevant to the intestinal microecosystem and hosts’ oligosaccharides. Many species should have co-evolved with their hosts, but the phylogeny of Bifidobacterium is dissimilar to that of host animals. The discrepancy could be linked to the niche-specific evolution due to hosts’ dietary carbohydrates. The distribution of carbohydrate-active enzymes, in particular glycoside hydrolases (GHs) that metabolize unique oligosaccharides was examined. When bifidobacterial species were classified by their distribution of GH genes, five groups arose according to their hosts’ feeding behaviour. The distribution of GH genes was only weakly associated with the phylogeny of the host animals or with genomic features such as genome size. Thus, the hosts’ dietary pattern is the key determinant of the distribution and evolution of GH genes.
