Abstract
Low doses of sorafenib have been shown to decrease portal pressure (PP), portal-systemic shunts, and liver fibrosis in cirrhotic rats. Nonselective beta blockers (NSBB) are the only drugs recommended for the treatment of portal hypertension. The aim of our study was to explore whether the combination of propranolol and sorafenib might show an additive effect reducing PP in cirrhotic rats. Groups of common bile duct-ligated cirrhotic rats (CBDL) and sham-operated control rats were treated by gavage with vehicle, propranolol (30 mg·kg(-1)·day(-1)), sorafenib (1 mg·kg(-1)·day(-1)), or propranolol+sorafenib. Treatment began 2 wk after the CBDL or sham operation. Hemodynamic evaluation was performed after 2 wk of treatment. In cirrhotic rats, propranolol and sorafenib produced a significant (P < 0.001) and similar reduction in PP (-19 and -15%, respectively). This was achieved through different mechanisms: whereas propranolol decreased PP by reducing portal blood flow (-35%; P = 0.03), sorafenib decreased PP without decreasing portal flow indicating decreased hepatic resistance. After propranolol+sorafenib, the fall in PP was significantly greater (-30%; P < 0.001) than with either drug alone, demonstrating an additive effect. However, the reduction in portal flow (-39%) under combined therapy was not significantly greater than after propranolol alone. Sorafenib, alone or in combination with propranolol, produced significant reduction in portal-systemic shunting (-25 and -33%, respectively), splanchnic vascularization (-37 and -41%, respectively), liver fibrosis (38%), and hepatic neovascularization (-42 and -51%, respectively). These effects were not observed after propranolol alone. In conclusion, the combination of propranolol+sorafenib causes a greater reduction in PP than either drug alone and decreases markedly the extent of portal-systemic shunting, splanchnic and hepatic neovascularization, and liver fibrosis, suggesting that this drug combination is a potentially useful strategy in the treatment of portal hypertension.

Abstract
INTRODUCTION We studied the differences on physical fitness, fatness and cardiovascular profile in Spanish and Moroccan women. MATERIAL AND METHODS The study comprised 63 and 58 women aged 45-65 years from South of Spain and North of Morocco, respectively. We assessed fitness and body composition using standard procedures. We also assessed resting heart rate (RHR), blood pressure, fasting glucose, total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides. RESULTS AND DISCUSSION Moroccan women had a better performance in the main health-related physical fitness components, i.e. higher levels of cardiorespiratory fitness (P = 0.01) and (lower-body) muscular strength (P < 0.001). Diastolic blood pressure (P = 0.004), RHR and total cholesterol (both P = 0.04) were lower in Moroccan women. No differences were observed in the prevalence of metabolic syndrome. CONCLUSIONS The women from Morocco had a healthier fitness and cardiovascular profile than the women from Spain. Further research on physical fitness and other health indicators in understudied populations is needed.

Abstract
The in vitro aqueous behaviour of a metacryloyloxyethyl [2-(acetyloxy)-4-(trifluoromethyl)]benzoate (THEMA)/N,N'-dimethylacrylamide (DMA) copolymer with a THEMA molar content of 39% (labeled THDMA39) has been investigated. This composition has been selected to achieve a system able to keep both the non-water solubility during the release and the resorbability (and the water solubility) after the completion of the drug release. This copolymer exhibited, at pH 7.4, a constant release during several months, very interesting for a long term treatments required for the application of some cardiovascular devices. A kinetic model has been developed to explain the pseudo-zero-order kinetics of the release process. This model, which considers (from the aqueous studies) a linear increase with time of the amount of water present in the polymeric matrix, has been able to fit adequately the experimental data.

Abstract
OBJECTIVE The aim of this 1-year follow-up study was to compare functional outcome as well as clinical differences between patients with first- and multiple-episode bipolar disorder. METHOD Bipolar disorder patients with first (n = 60) and multiple episodes (n = 59) were recruited from two hospitals in Spain. The Functioning Assessment Short Test (FAST) was used to assess functioning. The Hamilton Depression Rating Scale (HAMD) and the Young Mania Rating Scale (YMRS) were administered to assess mood symptoms. RESULTS As expected, patients with first episode experienced a greater functioning compared to patients with multiple episodes (11.26 ± 10.94 vs. 26.91 ± 13.96; t = 6.436, P < 0.001). There were significant demographic and clinical differences between both groups. Baseline depressive symptoms (F = 9.553, df = 4, 102; P < 0.001) and age (F = 14.145, df = 4, 103; P < 0.001) were significantly associated with poor functional recovery at 6-month and 12-month assessment, respectively, in a group of patients with multiple episodes. CONCLUSION Our data give support to the model of staging in bipolar disorder, showing that the enduring neurotoxicity of repeated episodes may contribute to sustained impairment in multiple areas of psychosocial functioning.

Abstract
The establishment of rat embryonic stem cells constitutes a precious tool since rat has been extensively used in biomedical research, in particular for the generation of human neurodisease animal models. Up to now only a few studies have described the isolation of rat embryonic stem-like cells. One out of 9 isolated rat embryonic stem-like cell lines (B1-RESC) obtained from a 4.5-day post-coitum blastocyst were extensively characterized and kept in culture for up to 80 passages on feeders with LIF. The stable growth of these cells and the expression of pluripotent markers were confirmed up to a high number of passages in culture, also in the absence of feeders and LIF. B1-RESC expresses the three germ layers markers both in vitro, within differentiating embryoid bodies, and in vivo through teratoma formation. Collectively, the B1-RESC line with a stable near-diploid karyotype can be used as a highly sensitive tool for testing anti-proliferative molecules.

Abstract
Some environmental contaminants interact with hormones and may exert adverse consequences as a result of their actions as endocrine disrupting chemicals (EDCs). Exposure in people is typically a result of contamination of the food chain, inhalation of contaminated house dust or occupational exposure. EDCs include pesticides and herbicides (such as dichlorodiphenyl trichloroethane or its metabolites), methoxychlor, biocides, heat stabilisers and chemical catalysts (such as tributyltin), plastic contaminants (e.g. bisphenol A), pharmaceuticals (i.e. diethylstilbestrol; 17α-ethinylestradiol) or dietary components (such as phytoestrogens). The goal of this review is to address the sources, effects and actions of EDCs, with an emphasis on topics discussed at the International Congress on Steroids and the Nervous System. EDCs may alter reproductively-relevant or nonreproductive, sexually-dimorphic behaviours. In addition, EDCs may have significant effects on neurodevelopmental processes, influencing the morphology of sexually-dimorphic cerebral circuits. Exposure to EDCs is more dangerous if it occurs during specific 'critical periods' of life, such as intrauterine, perinatal, juvenile or puberty periods, when organisms are more sensitive to hormonal disruption, compared to other periods. However, exposure to EDCs in adulthood can also alter physiology. Several EDCs are xenoestrogens, which can alter serum lipid concentrations or metabolism enzymes that are necessary for converting cholesterol to steroid hormones. This can ultimately alter the production of oestradiol and/or other steroids. Finally, many EDCs may have actions via (or independent of) classic actions at cognate steroid receptors. EDCs may have effects through numerous other substrates, such as the aryl hydrocarbon receptor, the peroxisome proliferator-activated receptor and the retinoid X receptor, signal transduction pathways, calcium influx and/or neurotransmitter receptors. Thus, EDCs, from varied sources, may have organisational effects during development and/or activational effects in adulthood that influence sexually-dimorphic, reproductively-relevant processes or other functions, by mimicking, antagonising or altering steroidal actions.

Abstract
INTRODUCTION The aim was to study whether nocturnal penile rigidity (NPTR) correlates with metabolic syndrome (MetS) and testosterone in men consulting for erectile dysfunction (ED). MATERIAL AND METHODS 234 men were included in a prospective, cross-sectional pilot study. Serum total and bioavailable testosterone and other biochemical constituents were measured and compared with NPTR. Patients were classified by normal or low/abnormal penile rigidity (abnormal meaning predominant organic component of ED) and presence or absence of MetS to test the hypothesized correlations. RESULTS Application of the logistic regression model to rigidity as the dependent variable showed the risk of low penile rigidity to be significantly lower for patients with higher total (OR=0.96, 95% CI=0.92-0.99) or bioavailable testosterone (OR=0.91, 95% CI=0.84-0.99). Patients with testosterone levels between 8 and 12 mmol/L had a quadrupled risk of low penile rigidity compared with patients with higher levels (>12 mmol/L) (OR=3.96, 95% CI=1.89-8.31). Considering men without MetS, age and body mass index were associated as significant factors for low penile rigidity: age increased risk by 8% (OR=1.08, 95% CI=1.03-1.13) and BMI increased it by 18% (OR=1.18, 95% CI=1.01-1.38). CONCLUSION Testosterone levels are weakly associated with penile rigidity and disappear when associated with MetS.

Abstract
Lipid rafts and mitochondria are promising targets in cancer therapy. The synthetic antitumor alkyl-lysophospholipid analog edelfosine (1-O-octadecyl-2-O-methyl-rac-glycero-3-phosphocholine) has been reported to target lipid rafts. Here, we have found that edelfosine induced loss of mitochondrial membrane potential and apoptosis in human cervical carcinoma HeLa cells, both responses being abrogated by Bcl-xL overexpression. We synthesized a number of new fluorescent edelfosine analogs, which preserved the proapoptotic activity of the parent drug, and colocalized with mitochondria in HeLa cells. Edelfosine induced swelling in isolated mitochondria, indicating an increase in mitochondrial membrane permeability. This mitochondrial swelling was independent of reactive oxygen species generation. A structurally related inactive analog was unable to promote mitochondrial swelling, highlighting the importance of edelfosine molecular structure in its effect on mitochondria. Raft disruption inhibited mitochondrial localization of the drug in cells and edelfosine-induced swelling in isolated mitochondria. Edelfosine promoted a redistribution of lipid rafts from the plasma membrane to mitochondria, suggesting a raft-mediated link between plasma membrane and mitochondria. Our data suggest that direct interaction of edelfosine with mitochondria eventually leads to mitochondrial dysfunction and apoptosis. These observations unveil a new framework in cancer chemotherapy that involves a link between lipid rafts and mitochondria in the mechanism of action of an antitumor drug, thus opening new avenues for cancer treatment.

Abstract
OBJECTIVE To analyze the prognostic value of thrombin activatable fibrinolysis inhibitor (TAFI) and C1040T polymorphism in acute myocardial infarction treated with fibrinolysis. To analyze C1040T polymorphism influence on its plasma level. DESIGN An observational, prospective study performed from November 2003 to November 2005 and with a 3 month follow-up. SETTING Intensive Medicine Service from a university-affiliated teaching hospital. PATIENTS A total of 53 patients with acute myocardial infarction with persistent ST segment elevation treated with the same fibrinolytic therapy. A control group of 53 biologically similar subjects was included. INTERVENTIONS None. MAIN MEASUREMENTS Baseline characteristics; frequency of wild-type genotype (Thr325Thr) and of those corresponding to the mutation (Thr325LLe and LLe325lle), TAFI levels at 6 h, 34 h and 3 months post-fibrinolysis; ejection fraction; Killip-Kimball; reperfusion; ischemic recurrence; death. RESULTS No relationship was found between biological features and TAFI concentration. The latter was significantly higher in infarct patients (p<0.01) and in the mutation group (p<0.01). The homozygotic mutation (Ile325Ile) was significantly higher in infarct patients (p<0.01). Reperfusion was significantly associated with lower body mass index (p=0.02. OR 0.22. 95% CI), ejection fraction (p=0.004. OR 0.91. 95% CI), triglyceride level (p=0.01. OR 1.02. 95% CI) and cholesterol levels (p=0.001. OR=0.84. 95% CI). Mutation was associated to a significant fall in post-fibrinolysis concentration TAFI antigen and functional TAFI (p=0.01) and (p=0.02), and lower frequency of reperfusion. Reperfusion was associated with a significant post-fibrinolysis reduction in the level of TAFI antigen (p=0.02). Recurrence was associated to a significantly higher post-fibrinolysis level (p=0.05. OR=0.84. 95% CI). This was more frequent in mutation. Post-fibrinolysis TAFI antigen concentration was significantly lower in non-recurrence patients (p=0.028. OR=1.03. 95% CI). CONCLUSIONS A higher concentration of TAFI is associated to a worse prognosis in reperfusion and recurrence in acute myocardial infarction treated with fibrinolysis. Homozygotic mutation was more frequent in myocardial infarction patients. Wild genotype is associated to a better prognosis. Mutation is associated to a higher expression of TAFI.

Abstract
IntroductionEarly onset forms of bipolar disorder may be difficult to distinguish from schizophrenia. Although operational criteria have become more precise, and there are more diagnostic systems to catalogue a psychotic adolescent, the clinicians continue having difficulties.ObjectiveTo know the stability of the diagnosis of definitively bipolar patients with psychotic symptoms during the episodes, and factors that can influence other psychotic diagnoses in the first episode of the illness.Method140 bipolar patients of Araba, (Basque country) were included during 2 years. Patients were divided into two groups: unstable diagnoses (UD)(bipolar patients with an initial diagnosis of other psychosis) and stable diagnoses (SD) of bipolar disorder. Clinical and sociodemographic data were obtained.ResultsThe mean age at onset was significantly lower in the UD group (p = 0.004). It was rare to have an unstable diagnosis when the first psychotic episode occurred after age 38 (p = 0.008). There were more singles in the UD group (p = 0.010).The presence of mood incongruent psychotic symptoms was more frequent in the UD group (p < 0.001).Mood incongruent psychotic symptoms variable was the only independent factor significantly associated with an unstable diagnosis in the multivariate analysis (p = 0.036).DiscussionOne third of the patients have been previously diagnosed with other psychotic illness.This study suggests that the most important factor is the clinical picture, especially the presence of mood-incongruent psychotic symptoms. A correct diagnosis is important because patients who are prescribed mood stabilizers have lower rates of rehospitalisation than those who are not treated with mood stabilizers.
