RESUMEN
The prevention of pre-eclampsia is difficult due to the syndromic nature and multiple underlying mechanisms of this severe complication of pregnancy. The current clinical distinction between early- and late-onset disease, although clinically useful, does not reflect the true nature and complexity of the pathologic processes leading to pre-eclampsia. The current gaps in knowledge on the heterogeneous molecular pathways of this syndrome and the lack of adequate, specific diagnostic methods are major obstacles to early screening and tailored preventive strategies. The development of novel diagnostic tools for detecting the activation of the identified disease pathways would enable early, accurate screening and personalized preventive therapies. We implemented a holistic approach that includes the utilization of different proteomic profiling methods of maternal plasma samples collected from various ethnic populations and the application of systems biology analysis to plasma proteomic, maternal demographic, clinical characteristic, and placental histopathologic data. This approach enabled the identification of four molecular subclasses of pre-eclampsia in which distinct and shared disease mechanisms are activated. The current review summarizes the results and conclusions from these studies and the research and clinical implications of our findings.

Onychomycosis is a disease that affects many adults, whose treatment includes both oral and topical therapies with low cure rates. The topical therapy is less effective but causes fewer side effects. This is why the development of an effective, easy to apply formulation for topical treatment is of high importance. We have used a nanotechnological approach to formulate Pickering emulsions (PEs) with well-defined properties to achieve site-specific delivery for antifungal drug combination of tioconazole and Melaleuca alternifolia essential oil. Silica nanoparticles with tailored size and partially hydrophobic surface have been synthesized and used for the stabilization of PEs. In vitro diffusion studies have been performed to evaluate the drug delivery properties of PEs. Ethanolic solution (ES) and conventional emulsions (CE) have been used as reference drug formulations. The examination of the antifungal effect of PEs has been performed on Candida albicans and Trichophyton rubrum as main pathogens. In vitro microbiological experimental results suggest that PEs are better candidates for onychomycosis topical treatment than CE or ES of the examined drugs. The used drugs have shown a significant synergistic effect, and the combination with an effective drug delivery system can result in a promising drug form for the topical treatment of onychomycosis.

In Hungary, the decline of traditional peasant culture and its heritage has prompted urban revivals, leading to the acceptance of traditional Hungarian folk singing as a performing arts genre. Drawing from a series of in-depth interviews, this study shows how contemporary Hungarian folk singers navigate (define, learn, police) different forms of authenticity within the field of folk music. While we find that objectified authenticity - heritagized classification systems - is the dominant form of symbolic capital, the broader symbolic economy of authenticity is complicated by competing definitions of folk singing as, variously, culture, heritage, and art. Third-person authenticity is more highly regarded, but it is more difficult for contemporary urban folk singers to achieve because they were not socialized in peasant communities. Therefore, they use objectified authenticity such as 'original recordings' as a proxy for learning about living folk culture. Although objectified authenticity constrains the agency of artistic expression, it affords discriminatory creativity (choosing one's own repertoire) and rationalized creativity (adapting traditional material to external values and contexts).
