Feasibility and challenges of performing magnetoencephalography experiments in children with arthrogryposis multiplex congenita

Arthrogryposis multiplex congenita (AMC) has recently drawn substantial attention from researchers and clinicians. New effective surgical and physiotherapeutic methods have been developed to improve the quality of life of patients with AMC. While it is clear that all these interventions should strongly rely on the plastic reorganization of the central nervous system, almost no studies have investigated this topic. The present study demonstrates the feasibility of using magnetoencephalography (MEG) to investigate brain activity in young AMC patients. We also outlined the general challenges and limitations of electrophysiological investigations on patients with arthrogryposis. We conducted MEG recordings using a 306-channel Elekta Neuromag VectorView system during a cued motor task performance in four patients with arthrogryposis, five normally developed children, and five control adults. Following the voice command of the experimenter, each subject was asked to bring their hand toward their mouth to imitate the self-feeding process. Two patients had latissimus dorsi transferred to the biceps brachii position, one patient had a pectoralis major transferred to the biceps brachii position, and one patient had no elbow flexion restoration surgery before the MEG investigation. Three patients who had undergone autotransplantation prior to the MEG investigation demonstrated activation in the sensorimotor area contralateral to the elbow flexion movement similar to the healthy controls. One patient who was recorded before the surgery demonstrated subjectively weak distributed bilateral activation during both left and right elbow flexion. Visual inspection of MEG data suggested that neural activity associated with motor performance was less pronounced and more widely distributed across the cortical areas of patients than of healthy control subjects. In general, our results could serve as a proof of principle in terms of the application of MEG in studies on cortical activity in patients with AMC. Reported trends might be consistent with the idea that prolonged motor deficits are associated with more difficult neuronal recruitment and the spatial heterogeneity of neuronal sources, most likely reflecting compensatory neuronal mechanisms. On the practical side, MEG could be a valuable technique for investigating the neurodynamics of patients with AMC as a function of postoperative abilitation

Cyclic peroxides and related initiating systems for radical polymerization of methyl methacrylate

Cyclic peroxides as initiators for the radical polymerization of methyl methacrylate were proposed. The initial rates, initiation rates, and effective activation energies of polymerization initiated by cyclic peroxides and cyclic peroxide-1-pyridyl-2-ferrocene systems were determined. The radical yields to the volume upon the thermal decomposition of cyclic peroxides and their catalytic decomposition in the presence of 1-pyridyl-2-ferrocene were determined. In combination with 1-pyridyl-2-ferrocene cyclic peroxides form efficient initiating systems favoring an increase in the polymerization rate, a decrease in the molecular weights, and an increase in syndiotacticity of the synthesized poly(methyl methacrylate). © 2013 Springer Science+Business Media New York

Direct transesterification of microalgae after Pulsed Electric Field ( PEF ) treatment

Background Lipid extraction is a major bottleneck for the commercialization of microalgae due to energy costs involved during solvent recycling. Direct transesterification offers the possibility to bypass the extraction step by immediately converting the lipids to fatty acids methyl esters (FAMEs). In this study, the efficiency of direct transesterification after pulsed electric field (PEF) was evaluated. Freshly harvested Auxenochlorella protothecoides (A. protothecoides), cultivated either autotrophically or mixotrophically, was subjected to PEF. Two treatment energies were tested, 0.25 MJ/kgdw and 1.5 MJ/kgdw and results were compared with conventional two-step transesterification. Results For autotrophically grown A. protothecoides, the percentage of the total FAMEs recovered from untreated biomass and microalgae treated with 0.25 MJ/kgdw was 30% for both cases while for 1.5 MJ/kgdw it was 65%. A 24-h incubation step between PEF-treatment and direct transesterification significantly improved the results. Untreated biomass remained stable with 30% of FAMEs, while with both treatment energies a 97% FAME recovery was achieved. However, for mixotrophic A. protothecoides the process was not as effective. Approximately 30% of FAMEs were recovered for all three conditions immediately after PEF with only a marginal increase after incubation. The reason for this different behavior of the two cultivation modes is unknown and under investigation. Conclusions Overall, the synergy between PEF and direct transesterification was proven to have potential, in particular for autotrophic microalgae. Its implementation and further optimization in a biorefinery therefore merits further attention

Mission and Socioeconomic Potential of the Company’s Anti-Corruption Audit in the Context of European Integration

Anti-corruption audit is an important tool in the current conditions, especially for companies operating in the context of European integration. The mission of anti-corruption audit in this context is to ensure compliance with transparency, ethics and rules of business conduct in conditions where corruption can cause negative consequences both for the company itself and for society as a whole. Anti-corruption audit is becoming a necessary element of the strategy for companies. It contributes to the creation of an honest and open business environment, which has a positive impact on the company’s relations with international partners. It also helps to make the business more competitive, maintain the trust of partners, investors and consumers, promotes socioeconomic development both at the company level and at the national level. The implementation of anti-corruption practices and measures has a direct impact on the investment climate, the competitiveness of enterprises, public trust, and the overall level of economic development. Achieving optimal results requires a system approach and active support from the company’s management or government. It is important to develop a clear anti-corruption policy, conduct education and training for staff, create a system of control and monitoring, and publicly disclose information about anti-corruption measures. This will help create a sustainable and ethical business environment, contribute to further development and integration into the European economy, foster the socioeconomic development of our country. Prospects for further research in this direction are: analysis of the efficiency of anti-corruption measures; research on how anti-corruption audit interacts with other aspects of European integration, such as reforms in the judiciary, human rights and legal reform; study of public attitudes towards anti-corruption measures and their impact on public opinion
