Institutional Balance in the EU. The Prodi Administration as a Reforming Commission

The essay looks at the Prodi Commission (1999-2004) in the context of the institutional balance in the European Union. Not only did Prodi come into office at a time of unprecedented weakness of the Executive, but the Commission operates within a changing institutional equilibrium, one made more precarious by the shifting political disposition of the Member States

Protective effect of intravitreal administration of tresperimus, an immunosuppressive drug, on experimental autoimmune uveoretinitis.

PURPOSE: To test the efficiency of locally administrated tresperimus in experimental autoimmune uveoretinitis (EAU). METHODS: EAU was induced in Lewis rats by S-antigen (S-Ag) immunization. Three intravitreal injections of tresperimus (prevention or prevention/treatment protocols) were performed at different time points after immunization. The pharmacokinetics of tresperimus was evaluated in the ocular tissues and plasma. The in vitro effect of tresperimus was evaluated on macrophages. EAU was graded clinically and histologically. Blood ocular barrier permeability was evaluated by protein concentration in ocular fluids. Immune response to S-Ag was examined by delayed type hypersensitivity, the expression of inflammatory cytokines in lymph nodes, ocular fluids and serum by multiplex ELISA, and in ocular cells by RT-PCR. RESULTS: In vitro, tresperimus significantly reduced the production of inflammatory cytokines by lipopolysaccharide-stimulated macrophages. In vivo, in the treatment protocol, efficient tresperimus levels were measured in the eye but not in the plasma up to 8 days after the last injection. Tresperimus efficiently reduced inflammation, retinal damage, and blood ocular barrier permeability breakdown. It inhibited nitric oxide synthase-2 and nuclear factor κBp65 expression in ocular macrophages. IL-2 and IL-17 were decreased in ocular media, while IL-18 was increased. By contrast, IL-2 and IL-17 levels were not modified in inguinal lymph nodes draining the immunization site. Moreover, cytokine levels in serum and delayed type hypersensitivity to S-Ag were not different in control and treated rats. In the prevention/treatment protocol, ocular immunosuppressive effects were also observed. CONCLUSIONS: Locally administered tresperimus appears to be a potential immunosuppressive agent in the management of intraocular inflammation.

La fonction rénale sous inhibition de l'enzyme de conversion de l'angiotensine [Renal function after administration of angiotensin-converting enzyme inhibitors]

Angiotensin converting enzyme (ACE) inhibitors are widely used today for the management of hypertension and congestive heart failure. These agents inhibit angiotensin II synthesis. In some particular circumstances they may be responsible for deterioration of renal function, e.g. in hypertensive patients with bilateral renal artery stenosis or with stenosis of the artery supplying a single kidney, or in patients with severe congestive heart failure or marked nephroangiosclerosis. In these patients renal perfusion pressure may become too low to maintain adequate glomerular filtration as there remains no angiotensin II to increase the tone of the efferent arteriole. In high risk patients it is therefore recommended that serum creatinine be checked after initiating therapy with an ACE inhibitor.

IPH Response to Dept of Justice and Equality Review of the Code of Practice on the Sale and Display of Alcohol in Mixed Trading Premises

IPH responded to the Department of Justice, Equality and Defence review of the voluntary Code of Practice for the display and sale of alcohol in supermarkets, convenience stores and similar mixed trading outlets. The voluntary Code was introduced in 2008 as an alternative to the statutory rules for structural separation of alcohol products in mixed trading outlets which are set out in section 9 of the Intoxicating Liquor Act 2008. Interested bodies and individuals were invited to submit comments on the Compliance Report for 2011 and on the effectiveness of the voluntary approach to structural separation by 20th December 2011. The Minister said he intended to also seek the views of the Minister for Health and the Joint Oireachtas Committee on Justice, Defence and Equality before reaching any decision on whether to bring the statutory rules in the 2008 Act into operation.

Guidelines for the safe administration of cytotoxic medical preparations in the treatment of patients with cancer

The Minister for Health’s Strategy for effective health care in the 1990s has emphasised quality of service as one of its key principles.  Within the medical sphere, almost no other field has developed and continues to expand as rapidly as that of cancer biology and treatment.  Cytotoxic therapies are a major part of these developments. The Cancer Strategy has highlighted the importance of these drugs in the treatment of cancers. Download the Report here

Carbon isotopic ratio analysis by gas chromatography/combustion/isotope ratio mass spectrometry for the detection of gamma-hydroxybutyric acid (GHB) administration to humans.

Since GHB (gamma-hydroxybutyric acid) is naturally produced in the human body, clinical and forensic toxicologists must be able to discriminate between endogenous levels and a concentration resulting from exposure. To suggest an alternative to the use of interpretative concentration cut-offs, the detection of exogenous GHB in urine specimens was investigated by means of gas chromatography/combustion/isotope ratio mass spectrometry (GC/C/IRMS). GHB was isolated from urinary matrix by successive purification on Oasis MCX and Bond Elute SAX solid-phase extraction (SPE) cartridges prior to high-performance liquid chromatography (HPLC) fractioning using an Atlantis dC18 column eluted with a mixture of formic acid and methanol. Subsequent intramolecular esterification of GHB leading to the formation of gamma-butyrolactone (GBL) was carried out to avoid introduction of additional carbon atoms for carbon isotopic ratio analysis. A precision of 0.3 per thousand was determined using this IRMS method for samples at GHB concentrations of 10 mg/L. The (13)C/(12)C ratios of GHB in samples of subjects exposed to the drug ranged from -32.1 to -42.1 per thousand, whereas the results obtained for samples containing GHB of endogenous origin at concentration levels less than 10 mg/L were in the range -23.5 to -27.0 per thousand. Therefore, these preliminary results show that a possible discrimination between endogenous and exogenous GHB can be made using carbon isotopic ratio analyses.

Effects of colostrum feeding and glucocorticoid administration on insulin-dependent glucose metabolism in neonatal calves

Colostrum feeding and glucocorticoid administration affect glucose metabolism and insulin release in calves. We have tested the hypothesis that dexamethasone as well as colostrum feeding influence insulin-dependent glucose metabolism in neonatal calves using the euglycemic-hyperinsulinemic clamp technique. Newborn calves were fed either colostrum or a milk-based formula (n=14 per group) and in each feeding group, half of the calves were treated with dexamethasone (30 microg/[kg body weight per day]). Preprandial blood samples were taken on days 1, 2, and 4. On day 5, insulin was infused for 3h and plasma glucose concentrations were kept at 5 mmol/L+/-10%. Clamps were combined with [(13)C]-bicarbonate and [6,6-(2)H]-glucose infusions for 5.5h (i.e., from -150 to 180 min, relative to insulin infusion) to determine glucose turnover, glucose appearance rate (Ra), endogenous glucose production (eGP), and gluconeogenesis before and at the end of the clamp. After the clamp liver biopsies were taken to measure mRNA levels of phosphoenolpyruvate carboxykinase (PEPCK) and pyruvate carboxylase (PC). Dexamethasone increased plasma glucose, insulin, and glucagon concentrations in the pre-clamp period thus necessitating a reduction in the rate of glucose infusion to maintain euglycemia during the clamp. Glucose turnover and Ra increased during the clamp and were lower at the end of the clamp in dexamethasone-treated calves. Dexamethasone treatment did not affect basal gluconeogenesis or eGP. At the end of the clamp, dexamethasone reduced eGP and PC mRNA levels, whereas mitochondrial PEPCK mRNA levels increased. In conclusion, insulin increased glucose turnover and dexamethasone impaired insulin-dependent glucose metabolism, and this was independent of different feeding.
