Over the last two decades, the European Union (EU) has increasingly relied on the use of restrictive measures in its external action. The EU has shown itself to be more open to the possibility of resorting to sanctions outside the United Nations, as well as in cooperation with other international actors, such as the United States. As a permanent member of the UN Security Council, Russia has blocked and is expected to block any efforts of using this international body to address the crisis in Ukraine so the EU cannot hope for a global sanctions regime and is forced to use a unilateral sanctions regime, in cooperation with some other like-minded players (US, Canada, Australia, Japan).

Summary. It is clear that any action to combat climate change must involve extensive efforts in reducing the greenhouse gas (GHG) emissions from the energy sector. In the EU, nearly 80% of total GHG emissions come from the energy sector (European Commission, 2011, p. 21). Any credible action within the EU on combating climate change therefore requires deep shifts in the way we produce and use our energy. This paper highlights that renewable energy policies to 2020 are insufficient to meet the EU’s long-term climate policy objectives of reducing GHG emissions by between 80 and 95% by 2050, and thereby aiming to avoid an increase in global temperatures of more than 2°C. Such an ambition would likely require a very high share of renewable energy (in the range of 80 to 100%) in the overall energy mix of the EU, given current uncertainties about the feasibility of potential technological developments (e.g. carbon capture and storage technology).

The Millennium Development Goals have led to tangible progress in many developing countries. Once adopted, the United Nations' new global Sustainable Development Goals will additionally require industrialized countries to implement such standards beginning in 2016. But the world's first comprehensive stocktaking shows that most industrialized nations are a long way from serving as role models for sustainable development.

"This booklet, published by the Statistical Office of the European Communities, updates the publication 'Statistics of Animal Production' of 1976. The statistics apply to the nine Member States of the Community. This publication is divided into four sections as follows: — Animal population (categories of animals, regions) (1973-1978) — Structure of breeding establishments (cattle and pigs) (1973, 1975, 1977) — Meat production (1968-1977) 'Meat' balance sheet and 'livestock' balance sheet (1976, 1977)"

During the last months, the number of reports on Holstein calves suffering from incurable idiopathic diarrhea dramatically increased. Affected calves showed severe hypocholesterolemia and mostly died within days up to a few months after birth. This new autosomal monogenic recessive inherited fat metabolism disorder, termed cholesterol deficiency (CD), is caused by a loss of function mutation of the bovine gene. The objective of the present study was to investigate specific components of lipid metabolism in 6 homozygous for the mutation (CDS) and 6 normal Holstein calves with different genotypes. Independent of sex, CDS had significantly lower plasma concentrations of total cholesterol (TC), free cholesterol (FC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), very-low-density lipoprotein cholesterol (VLDL-C), triacylglycerides (TAG), and phospholipids (PL) compared with homozygous wild-type calves ( < 0.05). Furthermore, we studied the effect of the genotype on cholesterol metabolism in adult Holstein breeding bulls of Swissgenetics. Among a total of 254 adult males, the homozygous mutant genotype was absent, 36 bulls were heterozygous carriers (CDC), and 218 bulls were homozygous wild-type (CDF). In CDC bulls, plasma concentrations of TC, FC, HDL-C, LDL-C, VLDL-C, TAG, and PL were lower compared with CDF bulls ( < 0.05). The ratios of FC:cholesteryl esters (CE) and FC:TC were higher in CDC bulls compared with CDF bulls, whereas the ratio of CE:TC was lower in CDC bulls compared with CDF bulls ( < 0.01). In conclusion, the CD-associated mutation was shown to affect lipid metabolism in affected Holstein calves and adult breeding bulls. Besides cholesterol, the concentrations of PL, TAG, and lipoproteins also were distinctly reduced in homozygous and heterozygous carriers of the mutation. Beyond malabsorption of dietary lipids, deleterious effects of apolipoprotein B deficiency on hepatic lipid metabolism, steroid biosynthesis, and cell membrane function can be expected, which may result in unspecific symptoms of reduced fertility, growth, and health.
