Self-association dynamics and morphology of short polymeric PBA-b/co-PAA surfactants

The self-association characteristics of very short and well-defined poly(butyl acrylate)-b-poly(acrylic acid) (PBA-b-PAA) block copolymers in water have been studied. The diblocks are asymmetric with the PBA block longer than the PAA block, giving rise to hollow sphere morphology. This is affirmed by experimental data and theoretical evaluations of the hydrophilic and hydrophobic domain sizes, as well as a value close to 1 for the ratio of the hydrodynamic to the gyration radius of the micelles. Besides, the untypically short PBA blocks (polymerization number around 15) render the micelles dynamic. Indications in support include among others the following: the CMC (critical micellar concentration) values depend, together with the aggregation numbers and the micellar sizes, on the block lengths, as predicted by theory; above the CMC their sizes are concentration-independent, while the micelles disappear below CMC. A comparison was also made with a random PBA-co-PAA copolymer of similar length, which self-associates at an apparent CMC 1 order of magnitude larger than those of the block copolymers, but the size of the formed micelles depends on the concentration

Chemoenzymatic Polymerization of l-Serine Ethyl Ester in Aqueous Media without Side-Group Protection

Poly(l-serine) (polySer) has tremendous potential as a polypeptide-based functional material due to the utility of the hydroxyl group on its side chain; however, tedious protection/deprotection of the hydroxyl groups is required for its synthesis. In this study, polySer was synthesized by the chemoenzymatic polymerization (CEP) of l-serine ethyl ester (Ser-OEt) or l-serine methyl ester (Ser-OMe) using papain as a catalyst in an aqueous medium. The CEP of Ser-OEt proceeded at basic pH ranging from 7.5 to 9.5 and resulted in the maximum precipitate yield of polySer at an optimized pH of 8.5. A series of peaks detected by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry revealed that the formed precipitate consisted of polySer with a degree of polymerization ranging from 5 to 22. Moreover, infrared spectroscopy, circular dichroism spectroscopy, and synchrotron wide-angle X-ray diffraction measurements indicated that the obtained polySer formed a β-sheet/strand structure. This is the first time the synthesis of polySer was realized by CEP in aqueous solution without protecting the hydroxyl group of the Ser monomer

Development of geraniol-loaded liposomal nanoformulations against salmonella colonization in the pig gut

Salmonella is a global health threat, with pig production being one of the main sources of human salmonellosis. The current study investigated the antivirulence properties of geraniol for inhibiting the in vitro colonization of Salmonella. The minimum inhibitory (MIC) and bactericidal concentrations (MBC) of geraniol against Salmonella typhimurium followed by the sub-MIC of geraniol were determined. Results provided clear evidence that geraniol at 1/8 MIC can be used as an effective, non-toxic antivirulence compound to inhibit virulence factors (motility, adhesion, and invasiveness) affecting the colonization of S. typhimurium on IPEC-J2 cells. Additionally, the findings signified that microfluidics is an emerging technology suitable for the preparation of stable liposomes with a small size (<200 nm) and high encapsulation efficiency (EE) of up to 92.53%, which can act as effective carriers of geraniol into the pig gastrointestinal tract (GIT), targeting Salmonella, preventing colonization, and thus increasing the safety of the food supply chain

Unpublished Mediterranean and Black Sea records of marine alien, cryptogenic, and neonative species

To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara.

Μεταξύ κεντρικού κράτους και τοπικής κοινωνίας: το ίδρυμα Σπίτια του Λαού και η άμβλυνση των μεταρρυθμίσεων στην Τουρκία (1932-1951)

During the formative years of the modern Turkish republic (1923-1950) the state embarked upon an extensive reform programme of modernization and nation-building. The Kemalist reform movement has been extensively studied in its institutional dimensions as a state project of top-down reform. This thesis studies modernist nation-building and state-society relations from a novel perspective through the case study of the People’s House, an institution aiming at the propagation of the modernist reforms to Turkey’s urban population in the 1930s and 1940s. Using hitherto unpublished archival material and provincial publications this work offers an alternative understanding of social change and state-society relations. In shifting the focus from the state as the fulcrum of change to the population’s participation in the process the thesis offers a ‘peripheral’ perspective of social change as it fashions a view from provincial towns. Focusing on everyday people it explores their participation in and experience of the new habits and mixed-gender socialization practices the modernist state was introducing in the People’s Houses, such as theatre, concerts, spots, dancing balls, and village excursions. Taping hundreds of petitions and complaint letters from the provinces it examines various ways ordinary people experienced, negotiated, and resisted the reforms and analyzes the ramifications of this process for the shaping of social and collective identities.Ευρύτερο αντικείμενό της είναι η μελέτη της χρήσης από κοινωνικά υποκείμενα εντός τοπικών κοινωνιών και σχέσεων εξουσίας των αντιλήψεων και πρακτικών που το νεωτερικό κράτος προσπάθησε να εισαγάγει στο πλαίσιο του προγράμματος μεταρρυθμίσεων στην Τουρκία στις δεκαετίες 1930 -1940.

Tek Parti Dönemini Yeniden Düşünmek: Devlet, Toplum ve Siyaset

Edited volume published in Turkish, focusing on the single-party period in Turkey. Book description: While the single-party period (1923-1945) is arguably the most studied period in the history of the Republic of Turkey, it is also the most decontextualized, mythologized and politicized one. Although there is a rich academic literature focusing on the period, written from very different perspectives and political positions, this literature largely reflects an elite-centred perspective that prioritizes the state, the policies of the central government and ideological debates. The point of departure for this edited volume is that the single-party period and the historiography regarding this period should be re-evaluated in the light of new perspectives and questions. The chapters that make up the volume show that single-party Turkey is shaped by much more complex dynamics than revealed by analyses based on dichotomies such as secular regime vs conservative people or centre vs. periphery , which dominate the existing literature. The chapters focus on different aspects of the early Republican period and look at state-society relations and the encounters of state and societal actors at all levels. The volume offers fresh and state of the art research that reveals the divisions and tensions within the state, acknowledges the power of social actors, and takes into account the interactions and negotiations between actors and institutions in both national and transnational contexts. Thus, the book proposes to understand the authoritarian regime of the single-party period by focusing on the daily practices of the state and without ignoring the ambiguities and inconsistencies inherent in the modernisation process.
