Authors: Roşu Alexandra Floriana , Ferreira Carlos Noronha , Ribeiro Luis Carrilho , Velosa José , Zlatian Ovidiu Mircea 
Published: January 2017

Abstract

Background. Morbid obesity is an important cause of morbidity and mortality. Bariatric surgery is the best option to manage obesity. Vertical gastrectomy is safe and effective but sometimes complicate with hemorrhage, fistulas and stenosis. Fistulas can be solved by conventional surgery or interventional endoscopy.

Case presentation. We describe a morbidly obese patient with vertical gastrectomy who developed complications after surgery. Immediately after surgery the patient developed sepsis. Upper gastrointestinal endoscopy excluded fistula. One month later a peri-gastric abscess developed due to a fistula orifice in the distal esophagus, treated with argon plasma and two double pigtail plastic stents placed endoscopically to drain the abscess. The stents were removed two weeks later and was placed a covered metallic stent in the distal esophagus. Six weeks later the metallic stent was removed and the orifice closed. Four months later the patient developed sepsis. Computer tomography revealed a subdiaphragmatic abscess and endoscopy revealed a 2 mm fistula orifice at the previous site, treated with argon plasma and two trough-the-scope clips that closed it. There were no further incidents after two years of follow-up.

Conclusions. Early diagnosis and endoscopic approach can resolve these complications without the morbidity and increased mortality risk of surgical re-interventions.

Abstract
In this study, we used an experimental design to investigate the influence of the total draft, break draft, distance between the aprons (Clips) and production roller pressure on yarn quality in order to obtain optimum drafting conditions for polyester and viscose (PES/CV) blend yarns in ring spinning frame. We used PES fibers (1.4 dtex × 38 mm long) and CV fibers (1.6 dtex × 38 mm long) to spin a 20 Tex blend yarn of PES (70%)/CV (30%) blend ratio. When the break draft, adjustment of distance between of aprons and roller pressure is not reasonable, controlling and leading of the fibers is not sufficient for proper orientation of the fibers in the yarn structure to produce a high quality yarn. Experimental results and statistical analysis show that the best yarn quality will be obtained under drafting conditions total draft of 38, 1.2 break draft, 2.8 mm distance between of aprons and maximum pressure of the production top roller (18daN).
Mandatory Pension System and Redistribution: The Comparative Analysis of Institutions in Baltic States
Authors: Dunajevas Eugenijus , Skučienė Daiva 
Published: January 2017

AbstractMandatory pension systems occupy a central role in the system of social security because of the share of social expenditure in national economies. One of the goals of pension system is to redistribute incomes among individuals. However, it is not clear how the intentions to redistribute incomes coincide with the outcomes. In this paper, we will study the difference between the intentions as they are articulated within institutions, with the outcomes that are generated by them. We use the method of comparative institutional analysis in order to find out the differences. Our comparative institutional analysis is based on the grammar of institutions that is proposed by Crawford and Ostrom. Also, in order to understand the differences, we will compare the institutions in relatively similar cases – the Baltic States. The results show that there is a gap between the intentions and outcomes to redistribute incomes among individuals. The findings from the comparative institutional analysis suggest that the most redistributive old age pension system is in Estonia. However, according to the factual information from Eurostat, the greatest distributive effect is produced by the mandatory pension system of Lithuania.
Adsorption with chemical reaction in porous catalyst pellets under alternate concentration fields. Uniform temperature case
Authors: Bizon Katarzyna , Tabiś Bolesław 
Published: January 2017

Abstract
The work concerns the dynamic behaviour of a porous, isothermal catalyst pellet in which a simultaneous chemical reaction, diffusion and adsorption take place. The impact of the reactant adsorption onto the pellet dynamics was evaluated. A linear isotherm and a non-linear Freundlich isotherm were considered. Responses of the pellet to sinusoidal variations of the reactant concentration in a bulk gas were examined. It was demonstrated that the dynamics of the pellet is significantly affected both by accounting for the adsorption and by the frequency of the bulk concentration variations. The sorption phenomenon causes damping of the concentration oscillations inside the pellet and damping of its effectiveness factor oscillations. Depending on the frequency of the concentration oscillations in the bulk, the remarkable oscillations can involve an entire volume of the pellet or its portion in the vicinity of the external surface.

Published: January 2017

Abstract
Managing inventory is considered as one of the
most challenging tasks facing supply chain managers and
specialists. Decisions related to inventory locations along
with level of inventory kept throughout the supply chain
have a fundamental impact on the response time, service
level, delivery lead-time and the total cost of the supply
chain. The main objective of this paper is to identify and
analyse the share of a particular logistic model adopted
in the Czech Republic (Consignment stock, Buffer stock,
Safety stock) and also compare their usage and adoption
according to different industries. This paper also aims to
specify possible reasons of particular logistic model preferences
in comparison to the others. The analysis is based
on quantitative survey held in the Czech Republic.

Using Sectoral Indexes to Discount the Exercise Price of Employee Stock Options
Authors: Majewska Agnieszka 
Published: January 2017

Abstract
Employee stock options (ESOs) are an instrument in compensating top management of corporations. In the literature, they are described as a variable component of remuneration of a long-term character (Borkowska, 2012). There are six characteristic elements of the ESO: a grant date, the ESO plan duration, employees entitled to receive options, vesting criteria, a vesting period, and an exercise price. The article refers to the exercise price. The remuneration of employees is determined by the option’s intrinsic value, i.e. the difference between the current stock price and the exercise price. This difference affects the costs incurred by a company in relation with their incentive stock option plan. In this connection, the exercise price of stock options needs to be analysed.
The literature shows that usually the strike price is equal to the stock market’s value at the time the option is granted. The options issued with an exercise price equal to the market value of the company’s stock on the date of the grant usually lead to at-the-money options. Walker (2009) mentions that almost all options issued by US firms have been such type of options. Hence, the options with exercise prices less than the prices of the underlying assets have been rarely observed. One of the solutions can be discounting the exercise price by using sectoral indexes, which are sensitive to changes on a particular market.
The purpose of this paper is to address several aspects of specifying the exercise price in ESOs. The research shows how sector indexes can be used to discount it. Using sectoral indexes in determining the exercise price can partly limit the unreasonably high profits from the ESO. The literature does not provide ready-made formulas of exercise prices based on specific variables. The aim of the research is to present and apply the formula of the exercise prices in which sectoral indices are used to discount.
The data are from the Warsaw Stock Exchange (WSE) and include those companies that revealed the information concerning their incentive programs in 1999–2013. The relevant data come from annual reports, current reports, supervisory boards’ resolutions, and press announcements.
Vitamin K2 Improves Anxiety and Depression but not Cognition in Rats with Metabolic Syndrome: a Role of Blood Glucose?
Authors: Gancheva Silvia M. , Zhelyazkova-Savova Maria D. 
Published: January 2017

AbstractBackground:The metabolic syndrome is a socially important disorder of energy utilization and storage, recognized as a factor predisposing to the development of depression, anxiety and cognitive impairment in humans.Aim:In the present study we examined the effects of vitamin K2 on the behavior of rats with metabolic syndrome and looked for relationships with the effects on blood sugar.Materials and methods:Male Wistar rats were divided in four groups: a control group on a regular rat chow, a metabolic syndrome (MS) group fed a high-fat high-fructose diet, a control group treated with vitamin K2 and a MS group treated with vitamin K2. Vitamin K2 was given by gavage. At the end of the study (after 10 weeks) behavioral tests were performed and fasting blood glucose was measured. Anxiety was determined using the social interaction test and depression was assessed by the Porsolt test. Memory effects were estimated by the object recognition test. Correlations between fasting blood glucose and behavioral performance were analyzed.Results:The rats from the MS group had elevated blood glucose. They had anxiety, depression and memory deficit. Vitamin K2 normalized blood glucose, reduced anxiety and depression, but did not improve memory. Time of social interaction (inverse index of anxiety) and memory recognition were negatively correlated with blood glucose in the untreated rats but the immobility time (measure of depression) was not. When vitamin K2-treated rats were added, the correlation of blood glucose with the time of social interaction was kept, but the one with the recognition memory was lost. It might be that the anxiolytic effect of vitamin K2 in this setting is at least partly due to its effects on blood glucose, while the anti-depressant effect is glucose-independent.Conclusion:The present study demonstrated that vitamin K2 prevented the development of anxiety and depression, but did not improve the memory deficit caused by the dietary manipulation in an experimental model of metabolic syndrome. It might be that the anxiolytic effect of vitamin K2 is at least partly due to its effects on blood glucose, while the antidepressant effect is glucose-independent.
Landolphia owariensis Attenuates Alcohol-induced Cerebellar Neurodegeneration: Significance of Neurofilament Protein Alteration in the Purkinje Cells
Authors: Oyinbo Charles A. , Igbigbi Patrick S. , Avwioro Godwin O. 
Published: January 2017

Abstract
Background: Alcohol-induced cerebellar neurodegeneration is a neuroadaptation that is associated with chronic alcohol abuse. Conventional drugs have been largely unsatisfactory in preventing neurodegeneration. Yet, multimodal neuro-protective therapeutic agents have been hypothesised to have high therapeutic potential for the treatment of CNS conditions; there is yet a dilemma of how this would be achieved. Contrarily, medicinal botanicals are naturally multimodal in their mechanism of action.
Aim: The effect of L. owariensis was therefore assessed in alcohol-induced neurodegeneration of the cerebellar cortex in rats.
Materials and methods: Two groups of rats were oro-gastrically fed thrice daily with 5 g/kg ethanol (25% w/v), and 5 g/kg ethanol (25% w/v) plus L. owariensis (100 mg/kg body weight) respectively in diluted nutritionally complete diet (50% v/v). A control group was correspondingly fed a nutritionally complete diet (50% v/v) made isocaloric with glucose. Cytoarchitectural study of the cerebellar cortex was examined with H&E. Immunocytochemical analysis was carried out with the use of monoclonal antibody anti-NF in order to detect alterations in the neuronal cytoskeleton.
Results: After 4 days of binge alcohol treatment, we observed that L. owariensis supplementation significantly lowered the levels of histologic and biochemical indices of neurodegeneration. The level of neurodegeneration and cytoarchitecture distortion of the cerebellar cortex of rats exposed to ethanol was reduced by L. owariensis. Neurofilament-immunoreactivity (NF-IR) was evoked in the Purkinje cells of rats that received L. owariensis supplement.
Conclusions: L. owariensis attenuates alcohol-induced cerebellar degeneration in the rat by alleviating oxidative stress and alteration of NF protein expression in the Purkinje cells.

New Developments in the Treatment of Acute Myocardial Infarction Associated with Out-of-Hospital Cardiac Arrest. A Review
Authors: Marton-Popovici Monica , Glogar Dietmar 
Published: January 2017

Abstract
Out-of-hospital cardiac arrest (OHCA) occurring as the first manifestation of an acute myocardial infarction is associated with very high mortality rates. As in comatose patients the etiology of cardiac arrest may be unclear, especially in cases without ST-segment elevation on the surface electrocardiogram, the decision to perform or not to perform urgent coronary angiography can have a significant impact on the prognosis of these patients. This review summarises the current knowledge and recommendations for treating patients with acute myocardial infarction presenting with OHCA. New therapeutic measures for the post-resuscitation phase are presented, such as hypothermia or extracardiac life support, together with strategies aiming to restore the coronary flow in the resuscitation phase using intra-arrest percutaneous revascularization performed during resuscitation. The role of regional networks in providing rapid access to the hospital facilities and to a catheterization laboratory for these critical cardiovascular emergencies is described.

The civil proceedings as a form of settling civil litigations is governed by different principles. Among these stands out the principle of good faith, which involved the exercise in good faith of rights in both civil and procedural matters, the exercise in good faith of procedural rights, a principle which has gained new meanings after the entry into force of the new Code of Civil Procedure, as well as the new Civil Code.
Considerations on the Best Interests of the Child as a Principle of Exercising Parental Authority
Authors: Bobar Cosmina Flavia 
Published: January 2017

Abstract
The principle of the best interests of the child is the basis for international or national normative documents adopted after the 1989 UN Convention on the Rights of the Child. They enshrine the prevalence of this principle in any decision that must be made with regard to the child, and regardless of its author.
In the matter of parental authority, the Romanian Civil Code subordinates parental rights and duties to this principle, placing the interests of the child above the interests of parents.
This study presents such aspects as referring to the principle of the best interests of the child, including from a historical perspective, while also emphasising concern in the doctrine for defining but also establishing criteria to appraise the best interests of the child, prior to the amendment of Law no. 272/2004 on the protection and promotion of children’s rights.
Transformation of the System of Values of Autonomous Learning for English Acquisition in Blended E-Studies for Adults: A Holistic Fractal Model
Authors: Bojāre Ināra , Skrinda Astrīda 
Published: January 2017

Abstract
The present study is aimed at creating a holistic fractal model (HFM) of autonomous learning for English acquisition in a blended environment of e-studies in adult nonformal education on the basis of the theories and paradigms of philosophy, psychology and education for sustainable development to promote the development of adult learners’ experiences of English acquisition. Thus, the present research attempts to find out how autonomous learning influences transformation of the system of values and integration in the learning environment. The research is based on the holistic paradigm of science. Adults’ English learning experience, their readiness to learn the language in blended e-studies and the SWOT analysis of metacognitive strategies are investigated in the paper. The authors also put forward recommendations for facilitating the transformation of the system of values in the process of autonomous learning for English acquisition in blended e-studies. The research has resulted in the HFM that interprets the systemic view on the transformation of values in the environment in the classroom and virtual environment, shows more holistic comprehension of the deepness and structure of the complexity of language learning and makes a methodological basis for its holistic facilitation in blended e-studies for adults.
Peatlands and their protection: select landscape parks of the Wielkopolska region
Authors: Ilnicki Piotr , Górecki Krzysztof , Lewandowski Piotr 
Published: January 2017

AbstractIn the context of five significantly different landscape parks in Wielkopolska (30,413 ha) 243 peatlands have been presented in terms of their characteristics, stratigraphy, change in means of utilisation and localisation. Thus trends in the change of peatland utilisation means in the period 1970–2016 were established and the resulting negative effects indicated. For this purpose the process of peatland protection established was analysed in the context of management plans carried out for both the protection of landscape parks and Natura 2000 sites within their territory. The above management plans, however, do not provide information as to localisation data, stratigraphy and to what purpose peatlands are used, which in all cover 2,690 ha – 4.2% of parks’ area. Most often this means there are no formal applications for their protection. This could be said to be a biproduct of a lack of discussion as to the major threat to the environment presented by the increasing disappearance of peatlands – a result of the mineralisation and moorsh process of peat soils. To a large extent the former has resulted from a lack of scientific expertise in respect to soils, peats and land reclamation in research teams preparing landscape management plans.
