Abstract
Ibuprofen (IBP) is an anti-inflammatory drug found in aquatic environments, potentially toxic for the biota. We exposed the test fish C. decemmaculatus to two environmentally relevant concentrations (50 and 100 μg IBP/L) for 4 and 12 d and evaluated the effect on some biomarkers. Micronucleus test, nuclear abnormality test and comet assay indicated cyto-genotoxicity at both concentrations and exposure periods. Oxidative stress and biochemical biomarkers were not affected, excepting muscle AChE activity for 4 d. Muscle metabolic biomarkers showed significant decrease in ETS, lipid and protein content, while carbohydrate content was not affected. The CEA index increased at the lower IBP concentration for 4 and 12 d, possibly due to changes in body energy reserves. A full-factorial GLM performed to assess the effects of IBP and exposure times showed that the metabolic and genotoxicity biomarkers were the most sensitive to IBP toxicity, mainly at 50 μg IBP/L for 4 d.

Abstract
The interactions among different electroejaculation devices associated with serial or continuous stimuli were investigated to improve the efficiency of the electroejaculation for semen collection in agoutis. Ten sexually matured male Dasyprocta leporina were restrained by the intramuscular administration of xylazine-ketamine association. Each individual was randomly subjected to four electroejaculation protocols, by combining two devices (one presenting longitudinal electrodes emitting square waves and other presenting ring electrodes emitting sine waves) and two electrical stimuli protocols (serial or continuous). A total of 40 attempts for electroejaculation were conducted in agoutis, being 10 per treatment. The most efficient treatment in providing ejaculates containing sperm (p < 0.05) was that using and electroejaculator connected to a probe with ring electrodes and associated with serial stimuli (4/7; 57%). In spite of semen parameters obtained by sine waves were adequate for using the samples for assisted reproduction, higher values for sperm motility and functional membrane integrity were obtained in the use of the square wave, independently of the electric stimulation protocol used (p < 0.05). In conclusion, we verified that the use of a device presenting a probe with ring electrodes and emitting sine waves, associated with a serial stimuli protocol, improves the efficiency for semen obtaining by electroejaculation in adults D. leporina.

Abstract
Estrogen deficiency accelerates the development of several disorders including visceral obesity and hepatic steatosis. The predisposing factors can be exacerbated by drugs that affect hepatic lipid metabolism. The aim of the present work was to determine if raloxifene, a selective estrogen receptor modulator (SERM) used extensively by postmenopausal women, affects hepatic fatty acid oxidation pathways. Fatty acids oxidation was measured in the livers, mitochondria and peroxisomes of ovariectomized (OVX) rats. Mitochondrial and peroxisomal β-oxidation was inhibited by raloxifene at a concentration range of 2.5-25 μM. In perfused livers, raloxifene reduced the ketogenesis from endogenous and exogenous fatty acids and increased the β-hydroxybutyrate/acetoacetate ratio. An increase in ¹⁴CO₂ production without a parallel increase in the oxygen consumption indicated that raloxifene caused a diversion of NADH from the mitochondrial respiratory chain to another oxidative reaction. It was found that raloxifene has a strong ability to react with H₂O₂ in the presence of peroxidase. It is likely that the generation of phenoxyl radical derivatives of raloxifene in intact livers led to the co-oxidation of NADH and a shift of the cellular redox state to an oxidised condition. This change can perturb other important liver metabolic processes dependent on cellular NADH/NAD⁺ ratio.

Abstract
The compositions of the essential oils from the leaves and flowers of Hedychium gardnerianum and from the leaves of Pittosporum undulatum growing on San Miguel Island (Azores) were investigated, and the compounds were identified by GC-MS analyses. The oils in the leaves and flowers of H. gardnerianum were rich in alpha-pinene, beta-pinene and alpha-cadinol, whereas that from P. undulatum was found to contain monoterpenes, sesquiterpenes, diterpenes and alkanes, of which the sesquiterpenes, calamenene (41.4%), farnesol (10.9%), spathulenol (5.6%) and beta-selinene (5.2%) and the diterpene (8beta,13beta)-kaur-16-ene (10.7%) were the major components. Their potential antimicrobial activities were tested against Staphylococcus aureus, S. epidermis and Pseudomonas aeruginosa, and those with the highest activities against S. aureus and S. epidermis were from H. gardnerianum; none had activity against P. aeruginosa. Additionally, the essential oils from Pittosporum undulatum had good antithrombin activity whereas that from H. gardnerianum did not.

Abstract
In order to assess lactoferrin (LF), stored in specific granules of neutrophils, as a marker of inflammation, LF was measured in plasma and serum samples of patients with active rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). In active RA, the median plasma LF level (800 ng/ml) was significantly higher than in normal individuals (220 ng/ml) (P less than 0.00001) and patients with active SLE (235 ng/ml) (P less than 0.00001). Median plasma elastase-proteinase inhibitor complex (EPIC) and C-reactive protein (CRP) levels were also significantly higher in patients with RA than in normal individuals (P less than 0.00001) and active SLE (P less than 0.00001 for both EPIC and CRP). Elevations of LF, EPIC and CRP in RA were independent of rheumatoid factor titres. Plasma lactoferrin in RA correlated significantly with EPIC (Rs = 0.7, P less than 0.0001), CRP (Rx = 0.72, P less than 0.0001) and absolute neutrophil counts (Rs = 0.483, P less than 0.02), but surprisingly not with the Ritchie index, with which CRP showed a weak but significant correlation (Rs = 0.27, P less than 0.05 greater than 0.025). Thus plasma LF and EPIC are markers of inflammation in RA and their levels may reflect release of mediators of inflammation into the joint space and periarticular tissue.
