Abstract
Deregulation of synaptic function and neurotransmission has been linked with the development of major depression disorder (MDD). Tianeptine (Tian) has been used as antidepressant with anxiolytic properties and recently as a nootropic to improve cognitive performance, but its mechanism of action is unknown. We conducted a proteomic study on the hippocampal synaptosomal fractions of adult male Wistar rats exposed to chronic social isolation (CSIS, 6 weeks), an animal model of depression and after chronic Tian treatment in controls (nootropic effect) and CSIS-exposed rats (lasting 3 weeks of 6-week CSIS) (therapeutic effect). Increased expression of Syn1 and Camk2-related neurotransmission, vesicle transport and energy processes in Tian-treated controls were found. CSIS led to upregulation of proteins associated with actin cytoskeleton, signaling transduction and glucose metabolism. In CSIS rats, Tian up-regulated proteins involved in mitochondrial energy production, mitochondrial transport and dynamics, antioxidative defense and glutamate clearance, while attenuating the CSIS-increased glycolytic pathway and cytoskeleton organization proteins expression and decreased the expression of proteins involved in V-ATPase and vesicle endocytosis. Our overall findings revealed that synaptic vesicle dynamics, specifically exocytosis, and mitochondria-related energy processes might be key biological pathways modulated by the effective nootropic and antidepressant treatment with Tian and be a potential target for therapeutic efficacy of the stress-related mood disorders.

Abstract
BACKGROUND The aim of the study was to evaluate the bioequivalence of two itraconazole 100 mg capsule formulations. RESEARCH DESIGN AND METHODS The single-center, open-label, randomized, three-period, three-sequence, reference-replicated, cross-over study included 38 healthy subjects under fed conditions. In each study period (separated by a 14-day washout), a single oral dose of the test (T) or reference (R) product was administered. Blood samples were collected at pre-dose and up to 72.0 h after administration. The calculated pharmacokinetic parameters, based on the plasma concentrations of itraconazole and hydroxy itraconazole, were AUC0-72h, AUC0-∝, Cmax, Tmax, T1/2 and Kel. RESULTS The 90% CI for the test/reference geometric means ratio for the parent compound, itraconazole, was in the range from 85.29% to 116.07% for AUC0-72h. Since the coefficient of variation (CV) for the reference product was 44.95% for Cmax, the 90% CI for this parameter for itraconazole was 93.49-133.78%, which was within the proposed limits of the EMA for bioequivalence of 72.15-138.59%. During the study, 4 subjects encountered a total of 14 mild adverse events. CONCLUSIONS The use of the reference-scaling approach with 3-period design (TRR, RTR, and RRT) was an efficient way to demonstrate that two commercially available oral itraconazole formulations met the predetermined bioequivalence criteria.

Abstract
BACKGROUND/AIM Based on numerous studies in animals, the most prominent toxic effects of decabrominated diphenyl ether (BDE-209) are observed in the liver, thyroid hormone homeostasis, reproductive and nervous systems. BDE-209 exhibits its toxic effects partly through the aryl hydrocarbon (Ah) receptor and consequent induction of hepatic microsomal enzymes. The aim of this study was to assess the hepatotoxic effect vs target tissue dose of BDE-209 in the subacutely orally exposed Wistar rats. METHODS Effects were examined on male Wistar rats, weighing 200-240 g, exposed to doses of 1;000, 2,000 or 4,000 mg BDE-209/kg body weight (bw)/day by gavage during 28 days. Animals were treated according to the decision of the Ethics Committee of the Military Medical Academy, No 9667-1/2011. Evaluation of the hepatotoxic effect was based on: relative liver weight water and food intake, biochemical parameters of liver function [aspartate amino transferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gama glutamyl transferase (γ-GT)], and oxidative stress parameters in liver homogenates [malondialdehiyde (MDA), superoxide dismutase (SOD), -SH] and morphological and pathohistological changes in the liver. For the assessment of internal dose-response relationship, lower confidence limit of Benchmark dose (BMDL) of 5% or 10% i.e. BMDL5 or BMDL10, were calculated using PROAST software. RESULTS After the application of 1,000,2,000 or 4,000 mg BDE-209/kg bw/day, the concentrations of BDE-209 measured in liver were 0.269, 0.569 and 0.859 mg/kg of liver wet weight, (ww) respectively. Internal doses correlated with external (r = 0.972; p < 0.05) according to equation: internal dose (mg BDE-209/kg of liver ww) = 0.0002 x external dose (mg/kg bw/day) + 0.0622. Hepatotoxicity was demonstrated based on significant increase in AST and γ-GT activities and the degree of histopathological changes. The lowest BMDLs of 0.07228 mg BDE-209 /kg of liver ww, correlating to external dose of 39 mg/kg/day, indicated the increase of AST activity as the most sensitive biomarker of BDE-209 hepatotoxicity in subacutely exposed rats. CONCLUSION The results of the present work add up to the issue ofBDE-209 toxicity profile with a focus on relationship between internal dose and hepatotoxicity. Critical internal dose for the effect on AST of 0.07 mg/kg of liver ww, corresponding to external dose of 39 mg/kg/ day, is the lowest dose ever observed among the studies on BDE-209 hepatotoxicity. For the persistent substances with low absorption rate such as BDE-209, critical effect based on internal dose in majority of cases is considered as more precisely deined than the effect established based on external dose, particularly.

Abstract
Chronic exposure to stress contributes to the etiology of mood disorders, and the liver as a target organ of antidepressant and antipsychotic drug metabolism is vulnerable to drug-induced toxicity. We investigated the effects of chronic administration of fluoxetine (15mg/kg/day) or clozapine (20mg/kg/day) on liver injury via the measurement of liver enzymes, oxidative stress and histopathology in rats exposed to chronic social isolation (21days), an animal model of depression, and controls. The activity of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), the liver content of carbonyl groups, malonyldialdehyde (MDA), reduced glutathione (GSH), cytosolic glutathione S-transferase (GST) and nitric oxide (NO) metabolites were determined. We also characterized nuclear factor-κB (NF-κB), cyclooxygenase-2 (COX-2) and CuZn-superoxide dismutase (CuZnSOD) protein expression as well as histopathological changes. Increased serum ALT activity in chronically-isolated and control animals treated with both drugs was found while increased AST activity was observed only in fluoxetine-treated rats (chronically-isolated and controls). Increased carbonyl content, MDA, GST activity and decreased GSH levels in drug-treated controls/chronically-isolated animals suggest a link between drugs and hepatic oxidative stress. Increased NO levels associated with NF-κB activation and the concomitant increased COX-2 expression together with compromised CuZnSOD expression in clozapine-treated chronically-isolated rats likely reinforce oxidative stress, observed by increased lipid peroxidation and GSH depletion. In contrast, fluoxetine reduced NO levels in chronically-isolated rats. Isolation induced oxidative stress but histological changes were similar to those observed in vehicle-treated controls. Chronic administration of fluoxetine in both chronically-isolated and control animals resulted in more or less normal hepatic architecture, while clozapine in both groups resulted in liver injury. These data suggest that clozapine appears to have a higher potential to induce liver toxicity than fluoxetine.

Abstract
It is widely recognised that flood risk needs to be taken into account when designing a storm sewer network. Flood risk is generally a combination of flood consequences and flood probabilities. This paper aims to explore the decision making in flood risk based storm sewer network design. A multiobjective optimization is proposed to find the Pareto front of optimal designs in terms of low construction cost and low flood risk. The decision making process then follows this multi-objective optimization to select a best design from the Pareto front. The traditional way of designing a storm sewer system based on a predefined design storm is used as one of the decision making criteria. Additionally, three commonly used risk based criteria, i.e., the expected flood risk based criterion, the Hurwicz criterion and the stochastic dominance based criterion, are investigated and applied in this paper. Different decisions are made according to different criteria as a result of different concerns represented by the criteria. The proposed procedure is applied to a simple storm sewer network design to demonstrate its effectiveness and the different criteria are compared.

Abstract
Recently increased flood events have been prompting researchers to improve existing coupled flood-models such as one-dimensional (1D)/1D and 1D/two-dimensional (2D) models. While 1D/1D models simulate sewer and surface networks using a one-dimensional approach, 1D/2D models represent the surface network by a two-dimensional surface grid. However their application raises two issues to urban flood modellers: (1) stormwater systems planning/emergency or risk analysis demands for fast models, and the 1D/2D computational time is prohibitive, (2) and the recognized lack of field data (e.g. Hunter et al. (2008)) causes difficulties for the calibration/validation of 1D/1D models. In this paper we propose to overcome these issues by calibrating a 1D/1D model with the results of a 1D/2D model. The flood-inundation results show that: (1) 1D/2D results can be used to calibrate faster 1D/1D models, (2) the 1D/1D model is able to map the 1D/2D flood maximum extent well, and the flooding limits satisfactorily in each time-step, (3) the 1D/1D model major differences are the instantaneous flow propagation and overestimation of the flood-depths within surface-ponds, (4) the agreement in the volume surcharged by both models is a necessary condition for the 1D surface-network validation and (5) the agreement of the manholes discharge shapes measures the fitness of the calibrated 1D surface-network.

Abstract
Intense rainfall in urban areas often generates both pluvial flooding due to the limited capacity of drainage systems, as well as fluvial flooding caused by deluges from river channels. The concurrence of pluvial and fluvial flooding can aggravate their (individual) potential damages. To analyse the impact caused by individual and composite type of flooding, the SIPSON/UIM model, an integrated 1D sewer and 2D overland flow was applied to numerical modelling. An event matrix of possible pluvial scenarios was combined with hypothetic overtopping and breaching situations to estimate the surface flooding consequences in the Stockbridge area, Keighley (Bradford, UK). The modelling results identified different flooding drivers in different parts of the study area and showed that the worst scenarios resulted from synthesised events.

Abstract
In order to successfully calibrate an urban drainage model, multiple calibration criteria should be considered. This raises the issue of adopting a method for comparing different solutions (parameter sets) according to a set of objectives. Amongst the global optimization techniques that have blossomed in recent years, Multi Objective Genetic Algorithms (MOGA) have proved effective in numerous engineering applications, including sewer network modelling. Most of the techniques rely on the condition of Pareto efficiency to compare different solutions. However, as the number of criteria increases, the ratio of Pareto optimal to feasible solutions increases as well. The pitfalls are twofold: the efficiency of the genetic algorithm search worsens and decision makers are presented with an overwhelming number of equally optimal solutions. This paper proposes a new MOGA, the Preference Ordering Genetic Algorithm, which alleviates the drawbacks of conventional Pareto-based methods. The efficacy of the algorithm is demonstrated on the calibration of a physically-based, distributed sewer network model and the results are compared with those obtained by NSGA-II, a widely used MOGA.

Abstract
The new simulation model, named SIPSON, based on the Preissmann finite difference method and the conjugate gradient method, is presented in the paper. This model simulates conditions when the hydraulic capacity of a sewer system is exceeded, pipe flow is pressurized, the water flows out from the piped system to the streets, and the inlets cannot capture all the runoff. In the mathematical model, buried structures and pipelines, together with surface channels, make a horizontally and vertically looped network involving a complex interaction of flows. In this paper, special internal boundary conditions related to equivalent inlets are discussed. Procedures are described for the simulation of manhole cover loss, basement flooding, the representation of street geometry, and the distribution of runoff hydrographs between surface and underground networks. All these procedures are built into the simulation model. Relevant issues are illustrated on a set of examples, focusing on specific parameters and comparison with field measurements of flooding of the Motilal ki Chal catchment (Indore, India). Satisfactory agreement of observed and simulated hydrographs and maximum surface flooding levels is obtained. It is concluded that the presented approach is an improvement compared to the standard "virtual reservoir" approach commonly applied in most of the models.

Abstract
Fifteen patients with metastatic non-seminomatous germ-cell tumours with good prognosis were treated with carboplatin-etoposide-bleomycine chemotherapy. Patients were followed-up from 8 to 56 months (median 32 months). In 13 patients there was no evidence of the disease and in 2 patients recurred, but recovered after the subsequent secondary chemotherapy (cisplatin-bleomycine-vincristine). Signs and symptoms of toxicity included alopecia in 93% of patients, nausea and vomiting in 40%, while in respect of haematological toxicity, leucopenia was observed in all 15 patients, thrombocytopenia in 80%, and decrease of haemoglobinaemia in 60% of patients. Other toxicities were not observed. Carboplatin-etoposide-bleomycine chemotherapy is effective and little toxic, but a greater number of patients and a longer follow-up are needed for definitive evaluatin of this therapy in the treatment of patients with metastatic non-seminomatous germ-cell testicular tumours with good prognosis.

Abstract
There have been many reports of the immunomodulatory effects of stress, but the influence of stress on anaphylaxis has been given little attention till now. In this study we investigated the influence of tail-shock stress on the course of anaphylactic shock (AS) in the rat. For this purpose, rats were sensitized to ovalbumin and subjected to stress procedure before the induction of AS. In the first series of experiments we used chronic (4 day) stress consisted of 80 inescapable tail shocks delivered at the same time each day. Anaphylactic shock was induced 24 hours later by intraperitoneal injection of 3 mg of ovalbumin. Results showed that stressed rats exhibited lower intensity of three investigated parameters of AS: clinical signs, hematocrit values, and drop of rectal temperature. In order to investigate whether acute stress procedure could also influence course of AS, rats were given various shock doses of ovalbumin immediately after the end of acute (1 day) tail-shock stress. Anti-anaphylactic effect of acute stress was demonstrated to be dose-dependent: the greatest protective effect was in animals that received the highest shocking dose of ovalbumin. Finally, we examined the duration of protective effect of acute inescapable tail shocks on AS, and these results showed that observed anti-AS phenomenon disappears 72 hours after the end of acute stress session.

Abstract
Numerous experiments have demonstrated that physical stress can alter immunological parameters. However, little attention has been paid to the interrelationship between stress and autoimmune processes. The present study was designed to determine the influence of electric shock and sound stress on the development of experimental allergic encephalomyelitis (EAE). Ten-week-old male DA rats highly susceptible to EAE were used. Rats were subjected to the stress procedure during 19 days either before or after immunization with intradermal injection of 0.1 ml of an emulsion containing guinea pig spinal cord (20 mg/rat) in an equal volume of complete Freund's adjuvant (CFA). In addition, rats received subcutaneous injection of Bordetella pertussis in the dorsum of the same foot. Electric stress procedure consisted of 80 inescapable, unpredictable tail shocks (5 s, 1 mA) delivered at the same time each day. Sound stress procedure consisted of exposure of rats to a 90 dB fire alarm bell which rings 60 times for 5 s during one hour, at the same time of the day. Rats were observed daily for clinical signs of EAE and survived animals were sacrificed on day 20 after immunization. The brain and spinal cord sections were examined histologically for mononuclear cell infiltrates characteristics for EAE. The results clearly indicate that inescapable tail shocks suppressed the appearance and development of EAE when rats were subjected to stress procedure during 19 days after immunization, but not when rats were stressed during 19 day before the induction of EAE. On the other hand, in rats exposed to sound stress there was only delay in the onset of the disease.
