Authors: Janicki Bogdan , Kochowicz Anna , Buzała Mateusz , Krumrych Wiesław 
Published: March 2013

Abstract
The study was conducted on 20 clinically healthy stallions, aged 3-4 years. The evaluation of the degree of adaptation of stallions to exercise loads in the course of a 100-d training programme was conducted three times: (I) - on the 1st d of training, (II) - on the 46th d of training, and (III) - on the 97th d of training. Rectal temperature (T) and number of heart and respiratory rates were measured. Blood was sampled before exercise (1), after exercise (2), and 30 min after rest (3). The following indices were determined in the blood: concentration of haemoglobin, haematocrit level, number of red blood cells, white blood cells, lymphocytes, neutrophils, eosinophils, basophils, monocytes, and platelets. Post-exertion changes in the evaluated indicators showed moderate intensity to the applied loads with respect to functional potential of tested horses. The effect of the standard 100-d training was to stimulate the body's adaptation to functional tasks, which was evidenced, among others, by lower variability of post-exertion T and the number of red blood cells. The highest T increase was found at the beginning of the programme (about 2.1%), whereas during the subsequent studies (II and III) it was significantly (P<0.05) lower (0.98% and 0.84%, respectively). The variability in red blood cell count in the course of training showed a downward trend (16.4%, 13.7%, and 11.0%, respectively). The results confirm the relatively low exercise loads and good health of young stallions during the 100-d performance test.
Influence of Beta-Endorphin on Oxygen Activity of Neutrophils and Total Antioxidant Status in Rats after Chronic Administration of Methimazole
Authors: Gołyński Marcin , Lutnicki Krzysztof 
Published: March 2013

Abstract
The aim of the study was to evaluate the effect of β-endorphin on oxygen activity of polimorphonuclear neutrophils and to investigate the total antioxidant status of blood serum in rats subjected to chronic treatment with methimazole. The study was carried out on 15 male Wistar rats weighing 270-290 g, divided into two groups. The animals from experimental group were administered a 0.05% drinking water solution of methimazole. The oxygen activity of peripheral blood neutrophils was examined using a modified RBA test. The extra-receptor effect of β-endorphin on the respiratory burst of neutrophils was evaluated. The incubation of neutrophils in the presence of phorbol myristate acetate (PMA) in the control group caused a nearly threefold increase in the oxygen activity of the cells compared to the control. Slightly higher values were obtained after addition of β-endorphin at the concentration of 10-6. Lower concentrations of this opioid (10-8 and 10-10) also stimulated oxygen activity but at a lower level than PMA. Naloxone did not affect the oxygen activity only when using β-endorphin in the concentration of 10-6. Naloxone and β-endorphin in the concentrations of 10-8 and 10-10 evoked a linear decrease in the oxygen activity of neutrophils, below the values obtained for PMA. The obtained results suggest that methimazole significantly modulates the generation of reactive oxygen species under the influence of β-endorphin, which stimulates the respiratory burst via the receptor pathway and inhibits it via the extra-cellular pathway. Methimazole also stimulates the anti-free radical defence.

Abstract
The aim of this study was to develop and examine a model of apoptosis and necrosis of hepatocytes induced by a damaging factor - adriamycin, correlating time after its administration with cell death type, and to investigate the localisation within the liver acinus of hepatocytes dying in these two ways. The results obtained in the present and previous studies were compared in order to make a map of cell death localisation in the liver acinus, showing the effect of time in action and dose of adriamycin. The experiment was performed on 32 female Wistar rats, divided into four groups: I and II - experimental, and III and IV - control. Adriamycin (3 mg/kg b.w.) was administered intraperitoneally to rats in groups I and II, and the rats were decapitated after four (group I) and eight (group II) weeks. Animals in control groups III and IV were given 0.5 mL of 0.9% NaCl solution, and decapitated after four and eight weeks respectively. Sections of the liver were examined with a three-stage immunohistochemical method. This method allowed to examine hepatocytes qualitatively and quantitatively for the presence of proteins involved in three types of apoptosis: induced by the mitochondrial pathway (caspase 3, 9), the intrinsic pathway related to endoplasmic reticulum stress (caspase 3, 12), and the extrinsic pathway (caspase 3, 8). One of the inflammatory markers, caspase 1, was also examined. The zonal localisation of all three types of apoptosis was assessed in the liver tissue. More oxidated hepatocytes indicated only signs of the internal mitochondrial pathway, whereas less oxidated hepatocytes induced the internal reticular pathway and the external apoptotic pathway. The period between adriamycin administration and hepatic cell investigation was a main factor of the process. A longer period post insult resulted in a more pronounced effect of the activation of apoptosis. Sections explored eight weeks after treatment with different doses of the drug (3 and 5 mg/kg in the previous study) showed a similar intensity of apoptosis.

Published: March 2013

Abstract
Sixteen white Wistar female rats were divided into two equal groups. Experimental group received per os 40 mg/kg b.w. of L-arginine, every other day for 2 weeks and were decapitated after 3 weeks of the experiment. Control rats received in the same manner 2 ml of distilled water and were decapitated after 3 weeks of the experiment. The renal lesions observed under electron microscope were of focal character and concerned only the experimental group. The tubules with necrotic cells were observed among normal tubules or single normal epithelial cells of the tubular wall. The boundaries between epithelial cells of the tubule wall were blurred. The mitochondria indicated abnormal structure. Numerous lysosomes and peroxysomes with dark, homogenous content were observed. The rough endoplasmic reticulum had widened channels and was focally completely destroyed. The nucleus of damaged cells was most commonly located in one of the cell poles; its shape was changed and visibly smaller than the nuclei of normal cells. Condensation and peripherally located chromatin were noticed. The lesions observed were characteristic for apoptotic cells.
A Fuzzy Approach for Bidding Strategy Selection
Authors: Ilieva Galina 
Published: March 2013

Abstract
The goal of this work is to explore the applicability of fuzzy logic in multiagent systems for choosing the best bidding strategy in electronic auction. To find the multi-criterion ordering, agents use a fuzzy algorithm ARAKRI2 with direct aggregation operators MaxMin and MinAvg. The key difference between this new approach and known from the literature solution FTNA is in the lack of weighted coefficients. Despite the difference both algorithms give results that are similar. Therefore, the proposed approach can successfully solve the task for multi criteria selection of bidding strategy.

Abstract
Eucalyptus is the tree of choice for wood production by farmers in Ethiopia. Although there are many claims about its harmful effect on ecology and water availability, little actual research exists. The main objective of this study was, therefore, to study the extent of harm of Eucalyptus on the ecosystem. This study was conducted at the Koga Watershed near Lake Tana in Ethiopia. Twenty-five farmers were interviewed and a field experiment with three replications was carried out to quantify the effect of Eucalyptus on various soil physical and chemical properties and maize crop measurements and to compare bulk density, soil moisture contents, maize crop counts and shading effects in fields bordered by Eucalyptus and Croton macrostachyus. Our results show that Eucalyptus decreased both soil nutrients and maize yields within 20 m of the trees. Although moisture content was not affected during the monsoon, it decreased faster within 30 m of the Eucalyptus trees than elsewhere. Soils become water repellent, too. Local farmers’ perception agreed with our experimental findings and indicated that Eucalyptus trees are exhausting the once productive land. They also reported that Eucalyptus dries up springs. Despite this, the growers insist on planting Eucalyptus because of its cash income.

Published: March 2013

Abstract
In vitro cultures of Leucojum aestivum are considered as an alternative for the production of galanthamine, which is used for the symptomatic treatment of Alzheimer’s disease. We studied the effects of auxins 2,4-dichlorophenoxyacetic acid (2,4-D), 4-amino-3,5,6-trichloropicolinic acid (picloram), 3,6-dichloro-o-anisic acid (dicamba) at concentrations of 25 and 50 µM on the induction of embryogenic callus and its capacity to induce somatic embryogenesis and alkaloid accumulation. The embryogenic response of the explants was from 30% for 25 µM of dicamba to 100% for picloram (for both 25 and 50 µM). 2,4-D (50 µM) stimulated greater callus proliferation and somatic embryo induction as compared to the other auxins. Polyethylene glycol (PEG) stimulated somatic embryo maturation. Callus grown on media containing 50 µM of auxins produced fewer phenolic compounds as compared with callus grown on media containing 25 µM of auxins. GC-MS analyses showed seven alkaloids in the in vivo bulbs and two to four in callus culture. Galanthamine was detected in callus cultivated with 2,4-D (25, 50 µM), picloram (25 µM), and dicamba (50 µM). Other alkaloids, trisphaeridine, tazettine, and 11-hydroxyvittatine were accumulated only in callus growing on medium with picloram (50 µM).

Abstract
Microalgae are an alternative and sustainable source of lipids that can be used as a feedstock for biodiesel production. Nitrate is a good nitrogen source for many microalgae and affects biomass and lipid yields of microalgae. In this study, the effect of nitrate on cell growth and lipid production and composition in Monoraphidium contortum, Tetraselmis suecica, and Chlorella minutissima was investigated. Nitrate affected the production of biomass and the production and composition of lipids of the three microalgae tested. Increasing the nitrate concentration in the culture medium resulted in increased biomass production and higher biomass productivity. Furthermore, increasing the nitrate concentration resulted in a reduction in lipid content and productivity in M. contortum; however, the opposite effect was observed in T. suecica and C. minutissima cultures. C. minutissima and M. contortum lipids contain high levels of oleic acid, with values ranging from 26 to 45.7% and 36.4 to 40.1%, respectively. The data suggest that because of its high lipid productivity (13.79 mg L−1 d−1) and high oleic acid productivity (3.78 mg L−1 d−1), Chlorella minutissima is a potential candidate for the production of high quality biodiesel.
Long term and seasonal ground deformation monitoring of Larissa Plain (Central Greece) by persistent scattering interferometry
Authors: Vassilopoulou Spyridoula , Sakkas Vasileios , Wegmuller Urs , Capes Ren 
Published: March 2013

AbstractThe land subsidence which occurs at the Larissa Basin (Thessaly Plain, Central Greece) is due to various causes including aquifer system compaction. Deformation maps of high spatial resolution deduced by the Persistent Scattering Interferometry (PSI) technique (using radar scenes from ERS and ENVISAT satellites) for the period 1992–2006 were produced to study the spatial and temporal ground deformation.A developed GIS database (including geological, tectonic, morphological, hydrological, meteorological and watertable variation from wells in the area) offered the possibility of studying in detail the intense subsidence. The PSI based average deformation image clearly shows that subsidence generally takes place inside the Larissa Plain ranging from 5–250 mm. The largest amplitude rates (−25 mm/yr) are observed around the urban area of Larissa City (especially at Gianouli and Nikea villages), while the Larissa City center appears to be relatively stable with a tendency to subside. The rest of the plain regions seem to subside at moderate rates (about 5–10 mm/yr). The surrounding mountainous area is stable, or has slightly been uplifted with respect to the NE located reference point. It was found that there is a correlation between the seasonal water-table variation (deduced from wells data), the seasonal water demand for irrigation associated with specific types of cultivation (cotton fields), the monthly rainfall, and the observed subsidence rate in the rural regions of the Thessaly Plain.

Published: March 2013

Summary
Background: Studies with single-session hyperbaric oxygen exposures have shown that HBO-induced oxidative stress is proportional to exposure pressure and duration. Since the efficacy of hyperbaric oxygen mainly depends on repetitive exposures, this study aimed to investigate the oxidative effect of hyperbaric oxygen administered for 5 to 40 sessions.
Methods: Sixty rats were divided into one control and 6 study groups. Study groups were exposed to 5, 10, 15, 20, 30, and 40 daily consecutive 2.8 atm/90 min hyperbaric oxygen sessions. Animals were sacrificed 24 h after the last hyperbaric oxygen administration. Malondialdehyde and carbonylated protein levels as well as superoxide dismutase activities were determined in isolated rat erythrocytes.
Results: Carbonylated protein levels increased significantly after just 5 hyperbaric oxygen exposures; reached a peak level with 10 exposures; were still significantly higher than controls after 15 sessions; and decreased to normal limits after 20 exposures. Malondialdehyde levels were found to be significantly increased in the 10 to 30, but not in the 5 and 40-session groups. Superoxide dismutase activity showed elevated levels only in the 5 and 10 times hyperbarical oxygen-exposed groups.
Conclusions: The suppressed oxidative stress level after 40 exposures suggests an effective endogenous antioxidant defense in repetitive HBO administrations.
Influence of Investment Projects on Dividend Policy of a Company in Conditions of Fuzzy Information
Authors: Jabłoński Bartłomiej 
Published: March 2013

Abstract
This article describes the problem of using fuzzy logic in the forecasts of variants of the results of implemented investment projects. It also shows the possibility of using calculations with the application of fuzzy triangular numbers L-R in the variants of results: an optimistic result, a pessimistic result and the most probable result (the central result). Moreover, the article draws attention to the possibility of using fuzzy numbers to estimate fuzzy risk of a forecasted financial result of a company. In addition, the article presents how a dividend may be shaped in consideration of multiplicity of variants if dividend policy takes into account dependence on company results as well as implemented investment projects.

Abstract
Introduction: Rheumatoid arthritis patients have an increased risk of cardiovascular morbidity and mortality. Consecrated cardiovascular risk management strategies are underused in this patients. The purpose of this paper is to evaluate, in rheumatoid arthritis hospitalized patients, the level of cardiovascular risk and the degree of implementation of currently recommended cardiovascular risk reduction treatments.
Materials and methods: 130 active rheumatoid arthritis patients, consecutively admitted in the Rheumatology Clinic of our hospital, were evaluated based on clinical exam, routine biochemistry, X-ray, electrocardiogram and cardiac ultrasound. We noted the characteristics of the rheumatic disease, the cardiovascular risk factors and organic heart disease. The risk for cardiac death at 10 years was estimated using the SCORE table; and adequate use of cardiovascular risk reduction therapies (antiaggregants, statin, antihypertensive medication) was checked.
Results: Organic heart disease was identified in 28.4% of the patients. The most frequent encountered risk factors were dyslipidemia (62.3%), hypertension (54.6%) and abdominal obesity (53%). Globally, 66,1% of the patients were classified as having high cardiovascular risk. Hypertension and dyslipidemia were treated in 81.6%, respective 40.7% of the cases and controlled to recommended therapeutic goals in 70.4%, respective 22.2%. Among the patients with a symptomatic atherosclerotic disease, less than one half (48.6%) were treated with antiaggregants.
Conclusion: Organic heart disease was frequent among rheumatoid arthritis patients; the most prevalent cardiovascular risk factors were hypertension, dyslipidemia and abdominal obesity. The treatment and control rates for hypertension were acceptable, but statins and antiaggregants were grossly underused.

Le pouvoir gris à l'épreuve du territoire
Authors: Argoud Dominique 
Published: March 2013

En France, la représentation des retraités et personnes âgées est en grande partie institutionnalisée aux niveaux national, régional et départemental. Pourtant, des initiatives locales existent visant à mieux associer les personnes vieillissantes à la définition de l’action publique sur un mode plus réflexif. Il en résulte une conception alternative du « pouvoir gris », beaucoup plus diffuse et moins centrée sur les catégories d’âge.

Dès lors que le progrès n’est plus notre mythe porteur, l’auteur des Voyages extraordinaires doit-il être renvoyé au musée ? La parution récente de quatre romans de Jules Verne dans la collection « Pléiade » pose la question de l’actualité de ce chantre des transformations techniques.
Pas de revenu inconditionnel sans revenu maximum acceptable
Authors: Lepesant Michel 
Published: March 2013

Droit au travail, efficacité économique, principe de justice, droit de propriété, participation à la création de richesses sont les principales justifications avancées dans les variantes du revenu inconditionnel (RI). Parmi celles-là, lesquelles pourraient convenir pour lier cette « belle revendication » du RI à celle d’un revenu maximum (d’un montant) acceptable (RMA) ? Comment RI et RMA, comme plancher et plafond d’un « espace écologique des revenus », forment-ils les deux conditions nécessaires pour une décroissance des inégalités, au cœur d’une société redevenue « commune », d’une société redéfinie comme « bien commun » ?
Le salaire universel : un déjà-là considérable à généraliser
Authors: Friot Bernard 
Published: March 2013

Le travail est aujourd’hui au rouet là où on ne sh’y attendait guère : dans les pays capitalistes développés. C’est que sa convention capitaliste y donne toute sa mesure mortifère. Mais elle est aussi – et c’est l’objet de cet article – controversée par une autre convention, salariale, conquise au XX e siècle en Europe occidentale. Cette convention repose sur la qualification personnelle, le salaire à vie qui lui est lié et sur la cotisation qui finance le long terme sans appel à l’épargne. Généraliser ces prémices d’un salaire universel, c’est-à-dire pour tous (reconnaissant à vie que chacun est qualifié) et pour tout (finançant l’investissement par sa partie socialisée dans une cotisation économique) est bien plus émancipateur – et plus réaliste, puisque le déjà-là est considérable - que mettre en place un revenu de base.
ARTICLE RETIRÉ : Du « matérialisme » de la pulsion : Zizek, lecteur de Lacan
Authors: Baas Bernard 
Published: March 2013

La théorie lacanienne des pulsions ne permet pas d’apporter une solution satisfaisante au problème que pose le concept freudien de pulsion de mort. C’est pourtant à partir de Lacan que Zizek entreprend de « forcer » la thèse de Freud pour repenser radicalement le sens de la pulsion de mort. Ce faisant, il entend souligner la dimension « matérialiste » de la pulsion et en révéler l’enjeu politique.
Lacan ironiste
Authors: Audi Paul 
Published: March 2013

Quel est le régime du discours que tient Lacan dans le Séminaire ? Suffit-il de le décrire comme un discours d’analysant pour en définir la teneur ? Ne participe-t-il pas, selon une modalité qui reste évidemment à préciser, des quatre discours dégagés par Lacan et réputés par lui être les seuls possibles ? En se posant ces questions, l’on pourrait peut-être commencer à comprendre quelle est la position éthique qui, aux yeux de Lacan lui-même, préside à la dispensation de son enseignement.
