The Legal Protection of Fundamental Human Values in Central and Eastern Europe and Modern Biotechnology: Towards European Harmonization

The protection of the fundamental human values (life, bodily integrity, human dignity, privacy) becomes imperative with the rapid progress in modern biotechnology, which can result in major alterations in the genetic make-up of organisms. It has become possible to insert human genes into pigs so that their internal organs coated in human proteins are more suitable for transplantation into humans (xenotransplantation), and micro-organisms that cam make insulin have been created, thus changing the genetic make-up of humans. At the end of the 1980s, the Central and Eastern European (CEE) countries either initiated new legislation or started to amend existing laws in this area (clinical testing of drugs, experiments on man, prenatal genetic diagnosis, legal protection of the embryo/foetus, etc.). The analysis here indicates that the CEE countries have not sufficiently adjusted their regulations to the findings of modern biotechnology, either because of the relatively short period they have had to do so, or because there are no definite answers to the questions which modern biotechnology has raised (ethical aspects of xenotransplantation, or of the use of live-aborted embryonic or foetal tissue in neuro-transplantation, etc.). In order to harmonise the existing regulations in CEE countries with respect to the EU and supranational contexts, two critical issues should be taken into consideration. The first is the necessity for CEE countries to recognise the place of humans within the achievements of modern biotechnology (a broader affirmation of the principle of autonomy, an explicit ban on the violation of the genetic identity of either born or unborn life, etc.). The second concerns the definition of the status of different biotechnological procedures and their permissibility (gene therapy, therapeutic genomes, xenotransplantation, etc.). The road towards such answers may be more easily identified once all CEE countries become members of the Council of Europe and express their wish to join the EU, which in turn presupposes taking over the entire body of EU legislation.

Private Publishing in Moscow and St. Petersburg: Historical Background, Present Situation and Trends"

This research was a complex study of the economic and socio-cultural aspects of the development of Russian private publishing in the second half of the19th and early 20th centuries, during the periods of 'war communism' and the New Economic Policy of 1917 to 1930, and during the reform of book publishing in 1986-1999. Conclusions about private book publishing in Moscow and St. Petersburg were extrapolated to Russia-wide problems of the development of this field. Svichenskaya sees her main achievement as having identified the economic and legal concepts behind the development of private book publishing over the period in question in the context of state and corporate regulation of publishing. Here the state was the main influence on its development and there was a paradox in the relations between the state authorities and private publishers, in that the latter constantly suffered from repression by the former but at the same time were dependent on state support. The research identified the administrative process of the liquidation of private publishing at the end of the 1920s and showed that its present flourishing is closely linked with the establishment of a preferential mode for the development of this sector. Private publishing now represents around 80% of domestic publishing, in terms both of the number of publishing houses and of the number of volumes published, and so plays the major role in satisfying the demand for books in Russia. Svichenskaya predicts that in the coming years private publishing will see a further concentration of growth and a tendency to monopolies and also the increasing specialisation of the publishing repertoire. She outlines a suggested concept of state management in publishing and ways to optimise this. In the transitional period of adaptation to the market regulation of publishing, these include a continuing degree of state protectionism, the creation of a favourable investment climate, privatisation of the printing companies with the aim of modernising these, and the development of coordinated corporate policies.

Academic Intelligence is not Enough! WICS: An Expanded Model for Effective Practice in School and in Later Life

Is there a psychological basis for teaching and learning in the context of a liberal education, and if so, what might such a psychological basis look like? Traditional teaching and assessment often emphasize remembering facts and, to some extent, analyzing ideas. Such skills are important, but they leave out of the aspects of thinking that are most important not only in liberal education, but in life, in general. In this article, I propose a theory called WICS, which is an acronym for wisdom, intelligence, and creativity, synthesized. The basic idea underlying this theory is that, through liberal education, students need to acquire creative skills and attitudes to generate new ideas about how to adapt flexibly to a rapidly changing world, analytical skills and attitudes to ascertain whether these new ideas are good ones, practical skills and attitudes to implement the new ideas and convince others of their value, and wisdom-based skills and attitudes in order to ensure that the new ideas help to achieve a common good through the infusion of positive ethical values.

Proteolytic processing of chemokines: implications in physiological and pathological conditions

Chemokines are small, secreted proteins that orchestrate the migration of cells, which are involved in immune defence, immune surveillance and haematopoiesis. However, chemokines are also implicated in the pathology of various inflammatory diseases, cancers and HIV. The chemokine system is considerably large and has a redundancy in the repertoire of its inflammatory mediators. Therefore, strict regulation of chemokine activity is crucial. Chemokines are the substrate for various proteases including the serine protease CD26/dipeptidyl-peptidase IV and matrix metalloproteinases. Regulation by proteolytic cleavage controls and fine-tunes chemokine function by either enhancing or reducing its chemotactic activity or receptor selectivity. Often chemokines and the proteases that regulate them are produced in the same microenvironment and expression of both may be simultaneously induced by a common stimulus enabling the rapid regulation of chemokine activity. The overall impact of cleaved chemokines in cellular responses is very complex. In this review, we will give an overview on chemokine modification and the respective chemokine modifying proteases. Furthermore, we will summarize the emerging literature describing the consequences in inflammation, haematopoiesis, cancer and HIV infection upon proteolytic chemokine processing.

COMBUSTION INITIATION BY ELECTRICAL-DISCHARGE-INDUCED PLASMA IN LEAN AND DILUTE METHANE-AIR MIXTURE: EXPERIMENTAL AND MODELING INVESTIGATION

This dissertation represents experimental and numerical investigations of combustion initiation trigged by electrical-discharge-induced plasma within lean and dilute methane air mixture. This research topic is of interest due to its potential to further promote the understanding and prediction of spark ignition quality in high efficiency gasoline engines, which operate with lean and dilute fuel-air mixture. It is specified in this dissertation that the plasma to flame transition is the key process during the spark ignition event, yet it is also the most complicated and least understood procedure. Therefore the investigation is focused on the overlapped periods when plasma and flame both exists in the system. Experimental study is divided into two parts. Experiments in Part I focuses on the flame kernel resulting from the electrical discharge. A number of external factors are found to affect the growth of the flame kernel, resulting in complex correlations between discharge and flame kernel. Heat loss from the flame kernel to code ambient is found to be a dominant factor that quenches the flame kernel. Another experimental focus is on the plasma channel. Electrical discharges into gases induce intense and highly transient plasma. Detailed observation of the size and contents of the discharge-induced plasma channel is performed. Given the complex correlation and the multi-discipline physical/chemical processes involved in the plasma-flame transition, the modeling principle is taken to reproduce detailed transitions numerically with minimum analytical assumptions. Detailed measurement obtained from experimental work facilitates the more accurate description of initial reaction conditions. The novel and unique spark source considering both energy and species deposition is defined in a justified manner, which is the key feature of this Ignition by Plasma (IBP) model. The results of numerical simulation are intuitive and the potential of numerical simulation to better resolve the complex spark ignition mechanism is presented. Meanwhile, imperfections of the IBP model and numerical simulation have been specified and will address future attentions.

Thromboelastometry for the assessment of coagulation abnormalities in early and established adult sepsis: a prospective cohort study

INTRODUCTION: The inflammatory response to an invading pathogen in sepsis leads to complex alterations in hemostasis by dysregulation of procoagulant and anticoagulant factors. Recent treatment options to correct these abnormalities in patients with sepsis and organ dysfunction have yielded conflicting results. Using thromboelastometry (ROTEM(R)), we assessed the course of hemostatic alterations in patients with sepsis and related these alterations to the severity of organ dysfunction. METHODS: This prospective cohort study included 30 consecutive critically ill patients with sepsis admitted to a 30-bed multidisciplinary intensive care unit (ICU). Hemostasis was analyzed with routine clotting tests as well as thromboelastometry every 12 hours for the first 48 hours, and at discharge from the ICU. Organ dysfunction was quantified using the Sequential Organ Failure Assessment (SOFA) score. RESULTS: Simplified Acute Physiology Score II and SOFA scores at ICU admission were 52 +/- 15 and 9 +/- 4, respectively. During the ICU stay the clotting time decreased from 65 +/- 8 seconds to 57 +/- 5 seconds (P = 0.021) and clot formation time (CFT) from 97 +/- 63 seconds to 63 +/- 31 seconds (P = 0.017), whereas maximal clot firmness (MCF) increased from 62 +/- 11 mm to 67 +/- 9 mm (P = 0.035). Classification by SOFA score revealed that CFT was slower (P = 0.017) and MCF weaker (P = 0.005) in patients with more severe organ failure (SOFA >or= 10, CFT 125 +/- 76 seconds, and MCF 57 +/- 11 mm) as compared with patients who had lower SOFA scores (SOFA <10, CFT 69 +/- 27, and MCF 68 +/- 8). Along with increasing coagulation factor activity, the initially increased International Normalized Ratio (INR) and prolonged activated partial thromboplastin time (aPTT) corrected over time. CONCLUSIONS: Key variables of ROTEM(R) remained within the reference ranges during the phase of critical illness in this cohort of patients with severe sepsis and septic shock without bleeding complications. Improved organ dysfunction upon discharge from the ICU was associated with shortened coagulation time, accelerated clot formation, and increased firmness of the formed blood clot when compared with values on admission. With increased severity of illness, changes of ROTEM(R) variables were more pronounced.

Women in Prostitution and Social Responsibility

The aim of the paper is to show how prostitution is embedded in historically changing gender relationships regulated by the state and part of each societies understanding of sexuality. An important role to improve the situation of women in prostitution is played by engaged social work, often linked to the womens movement on a local, national and an international level in spite of differing positions on the institution of prostitution. The authors argumentation is based on qualitative and quantitative empirical findings concerning shared experiences as well as differences between women in prostitution and findings on professional possibilities and limits of supporting the women. Important dimensions of heterogeneity amongst the women are legality versus illegality, decision making possibilities respectively dependencies und choice versus force, which also are the base of different political and professional positions taken by experts.

Who has really paid for the Reconstruction of East Germany? Expected and Realized Returns on Real Estate Investments in East and West Germany in the 1990s

We evaluate the profitability of investments in residential property in Germany after unification with a focus on the comparison of East and West Germany. Calculations are carried out for (1) the after-tax return an investor might have expected at the beginning of the 1990s, and (2) the after-tax return that has been realized ten years after. We compare a set of statistical data for investments in fifty major cities by using complete financial budgeting. The results show that tax subsidies could not always protect investors from losing money, but they have boosted realized returns after tax considerably. Therefore, it was indeed the taxpayers, not the investors, who have borne the cost of reconstructing East Germany.

Plant-microbe-herbivore interactions in invasive and non-invasive alien plant species

1. Plants interact with many organisms, such as microbes and herbivores, and these interactions are likely to affect the establishment and spread of plants. In the context of plant invasions, mycorrhizal fungi and constitutive and induced resistance of plants against herbivores have received attention independently of each other. However, plants are frequently involved in complex multi-trophic interactions, which might differ between invasive and non-invasive alien plants. 2. In a multi-species comparative experiment, we aimed to improve our understanding of plant traits associated with invasiveness. We tested whether eight invasive alien plant species use the mycorrhizal symbiosis in a more beneficial way, and have higher levels of constitutive or induced resistance against two generalist bioassay herbivores, than nine non-invasive alien species. We further assessed whether the presence of mycorrhizal fungi altered the resistance of the plant species, and whether this differed between invasive and non-invasive alien species. 3. While invasive species produced more biomass, they did not differ in their biomass response to mycorrhizal fungi from non-invasive alien species. Invasive species also did not have higher levels of constitutive or induced resistance against the two generalist herbivores. Mycorrhizal fungi greatly affected the resistance of our plant species, however, this was also unrelated to whether the alien species were invasive or not. 4. Our study confirms the previous findings that invasive species generally grow faster and produce more biomass than non-invasive alien species. We further show that alien plant species used a variety of defence strategies, and also varied in their interactions with mycorrhizal fungi. These multi-trophic interactions were not consistently related to invasiveness of the alien plant species. 5. We suggest that awareness of the fact that alien plant species are involved in multi-trophic interactions might lead to a more complete understanding of the factors contributing to a plant's success.

Concentration-dependent isoflurane effects on withdrawal reflexes in pigs and the role of the stimulation paradigm

In this prospective two-phase experimental trial, 10 pigs were anaesthetized twice with isoflurane only. In the first phase, the individual minimum alveolar concentration (MAC) was determined and in the second phase the effects on withdrawal reflexes of increasing end-tidal isoflurane concentrations (from 1.6% to 2.8%) were assessed. Single, 10 and 60 repeated electrical stimulations were used to evoke withdrawal reflexes which were recorded and quantified by electromyography. Recruitment curves for reflex amplitude for increasing stimulation intensities and isoflurane concentrations were constructed. Isoflurane MAC was 1.9+/-0.3%. Reflexes evoked by repeated stimulation were suppressed at isoflurane concentrations significantly higher than those which suppressed complex movements during MAC determination (P=0.014 and P=0.006 for 10 and 60 repeated stimuli respectively). Isoflurane up to 2.8% was still not able to abolish reflex activity evoked by repeated stimulations in all pigs. Single stimulation reflexes were suppressed at significantly lower concentrations than repeated stimulation reflexes (P=0.008 and P=0.004 for 10 and 60 repeated stimuli, respectively). Reflex amplitude was significantly correlated with isoflurane concentration (P<0.001, r=-0.85) independent of the individual MAC. The findings indicate that the level at which isoflurane suppresses withdrawal reflexes is dependent on the stimulation paradigm (single vs. repeated electrical stimulation), and there is limited value in expressing reflex withdrawal suppression in terms of MAC as purposeful and reflex movements are independently affected by isoflurane in individual animals.

Public health risks of enterobacterial isolates producing extended-spectrum β-lactamases or AmpC β-lactamases in food and food-producing animals: an EU perspective of epidemiology, analytical methods, risk factors, and control options

The blaESBL and blaAmpC genes in Enterobacteriaceae are spread by plasmid-mediated integrons, insertion sequences, and transposons, some of which are homologous in bacteria from food animals, foods, and humans. These genes have been frequently identified in Escherichia coli and Salmonella from food animals, the most common being blaCTX-M-1, blaCTX-M-14, and blaCMY-2. Identification of risk factors for their occurrence in food animals is complex. In addition to generic antimicrobial use, cephalosporin usage is an important risk factor for selection and spread of these genes. Extensive international trade of animals is a further risk factor. There are no data on the effectiveness of individual control options in reducing public health risks. A highly effective option would be to stop or restrict cephalosporin usage in food animals. Decreasing total antimicrobial use is also of high priority. Implementation of measures to limit strain dissemination (increasing farm biosecurity, controls in animal trade, and other general postharvest controls) are also important.

Acetabulum injuries in infancy and childhood

In this article, the anatomical and morphological features of the acetabulum in infancy and childhood are presented. The pathology and treatment of older children and adolescents is deliberately not covered, because the fracture morphology and treatment of patients aged 13 to 15 years is based on the criteria of adult medicine. Especially in the younger child, the anatomical differences are of particular importance. The younger the child is, the more difficult the diagnosis. Therefore today, MRI examinations should be generous used, even if anesthesia is necessary. If the injured child is hemodynamic stable, anesthesia can be electively used for a more complex diagnosis. Acetabular fractures are particularly problematic in infancy because even with optimal treatment and perfect reduction growth disturbances can occur. These manifest as so-called secondary dysplasia. During treatment, care should be taken to ensure that a surgical team having experience with the infant and juvenile skeleton is available and that appropriate implants are available.

Cochlear implantation in children and adults in Switzerland

The cochlear implant (CI) is one of the most successful neural prostheses developed to date. It offers artificial hearing to individuals with profound sensorineural hearing loss and with insufficient benefit from conventional hearing aids. The first implants available some 30 years ago provided a limited sensation of sound. The benefit for users of these early systems was mostly a facilitation of lip-reading based communication rather than an understanding of speech. Considerable progress has been made since then. Modern, multichannel implant systems feature complex speech processing strategies, high stimulation rates and multiple sites of stimulation in the cochlea. Equipped with such a state-of-the-art system, the majority of recipients today can communicate orally without visual cues and can even use the telephone. The impact of CIs on deaf individuals and on the deaf community has thus been exceptional. To date, more than 300,000 patients worldwide have received CIs. In Switzerland, the first implantation was performed in 1977 and, as of 2012, over 2,000 systems have been implanted with a current rate of around 150 CIs per year. The primary purpose of this article is to provide a contemporary overview of cochlear implantation, emphasising the situation in Switzerland.
