HALOPHYTES ,DURUM wheat ,STRESS management ,CHROMOSOMES ,FOOD crops ,SOIL salinization ,SPECIES - Abstract
Increased soil salinization, tightly related to global warming and drought and exacerbated by intensified irrigation supply, implies highly detrimental effects on staple food crops such as wheat. The situation is particularly alarming for durum wheat (DW), better adapted to arid/semi-arid environments yet more sensitive to salt stress than bread wheat (BW). To enhance DW salinity tolerance, we resorted to chromosomally engineered materials with introgressions from allied halophytic Thinopyrum species. "Primary" recombinant lines (RLs), having portions of their 7AL arms distally replaced by 7el1L Th. ponticum segments, and "secondary" RLs, harboring Th. elongatum 7EL insertions "nested" into 7el1L segments, in addition to near-isogenic lines lacking any alien segment (CLs), cv. Om Rabia (OR) as salt tolerant control, and BW introgression lines with either most of 7el1 or the complete 7E chromosome substitution as additional CLs, were subjected to moderate (100 mM) and intense (200 mM) salt (NaCl) stress at early growth stages. The applied stress altered cell cycle progression, determining a general increase of cells in G1 and a reduction in S phase. Assessment of morpho-physiological and biochemical traits overall showed that the presence of Thinopyrum spp. segments was associated with considerably increased salinity tolerance versus its absence. For relative water content, Na+ accumulation and K+ retention in roots and leaves, oxidative stress indicators (malondialdehyde and hydrogen peroxide) and antioxidant enzyme activities, the observed differences between stressed and unstressed RLs versus CLs was of similar magnitude in "primary" and "secondary" types, suggesting that tolerance factors might reside in defined 7el1L shared portion(s). Nonetheless, the incremental contribution of 7EL segments emerged in various instances, greatly mitigating the effects of salt stress on root and leaf growth and on the quantity of photosynthetic pigments, boosting accumulation of compatible solutes and minimizing the decrease of a powerful antioxidant like ascorbate. The seemingly synergistic effect of 7el1L + 7EL segments/genes made "secondary" RLs able to often exceed cv. OR and equal or better perform than BW lines. Thus, transfer of a suite of genes from halophytic germplasm by use of fine chromosome engineering strategies may well be the way forward to enhance salinity tolerance of glycophytes, even the sensitive DW.

microwave ablation ,directional heating ,operating frequency - Abstract
Recent studies have shown that ablation techniques have the potential to eradicate adrenal adenomas while preserving the functionalities of the adrenal gland and the surrounding anatomical structures. This study explores a new microwave ablation (MWA) approach operating at 5.8 GHz and using anatomical and dielectric characteristics of the target tissue to create directional heating patterns. Numerical simulations are executed in planar and 3D adrenal models, considering two energy doses. The numerical study is refined accounting for the vaporization of the tissue water content. Ex vivo experimental evaluations on porcine adrenal models complete the study. The numerical and experimental results show that spherical ablation zones are able to cover the target for both energy doses considered. Nonetheless, most of the non-targeted tissues can be preserved from excessive heating when low energy level is used. Numerical models accounting for water vaporization are capable to foresee the experimental temperature values. This study shows that the proposed MWA directional approach operating at 5.8 GHz can be considered for creating effective and selective ablation zones.

Theoretische Annahmen und Forschungsstand Die Gegenstandskonzeption ergibt sich aus einer Überschneidung unterschiedlicher Annahmen: Schülervorstellungen, politische Werthaltungen und Werturteile sind dabei gleichermaßen von Bedeutung. Politische Werthaltungen haben fachdidaktische Relevanz als erfahrungsbasierte Schülervorstellungen und werden nicht als explizierbare Einstellungen, sondern als implizites Wissen verstanden. Ein politisches Werturteil liegt hingegen auf einer expliziten Ebene (Bohnsack 2010). Werthaltungen werden als ein Bestandteil eines Werturteils angenommen. Forschung zu politischen Werturteilen auf einer impliziten Ebene sind weitestgehend ein Desiderat in der Politikdidaktik (Petrik 2011, S. 71). Durch die Rekonstruktion von politischen Werthaltungen mit der Dokumentarischen Methode ist diese Arbeit vor allem an Forschungen von Schelle (1995), Asbrand (2009), Thormann (2012), Winckler (2017) und Petrik (2013) anschlussfähig. Erkenntnisinteresse I. Wie verhalten sich die Schülerinnen und Schüler in Gruppendiskussionen und in Einzelarbeit zu einer Werturteilsaufgabe? II. Welche impliziten Werthaltungen lassen sich aus den Urteilen rekonstruieren? In welchem Verhältnis stehen explizite Werturteile und implizite Werthaltungen? III. Auf welche Wissensbestände greifen die Schülerinnen und Schüler bei der Bearbeitung zurück? Forschungsdesign In dem Forschungsprojekt wurden 36 Schülertexte und fünf Gruppendiskussionen an Gymnasien in Nordrhein-Westfahlen erhoben, mit der dokumentarischen Methode ausgewertet (vgl. Bohnsack 2014) und trianguliert (vgl. Helsper u.a. 2013). Dabei wurde ein Stimulus in Anlehnung an das Entscheidungsurteil (Detjen 2013) gewählt. Ergebnisse Die Studie liefert Erkenntnisse über den Zusammenhang von (Alltags-)Erfahrungen und der subjektiven Auseinandersetzung mit einer politischen Werturteilsfrage. Aus den Schülertexten konnten drei Metatypen von Werturteilen auf der expliziten Wissensebene hergeleitet und vier dokumentarische Typen von impliziten Werthaltungen rekonstruiert werden. Die Werturteile auf einer formulierenden Ebene orientieren sich an den Urteilskriterien Effektivität und Legitimität (Massing 2003). Darin drückt sich u.a. die Leistungsdimension einer schulischen Handlungspraxis aus. Auf einer impliziten Ebene konnten vier Typen von Werthaltungen rekonstruiert werden: Typ A, „Die Abwehrenden“, umkreist das Problem und zeigt eine ablehnende Haltung gegenüber Geflüchteten. Typ B, „Die Sachlichen“, orientiert sich an einer Sachzwanglogik und versteht politisches Handeln als vorstrukturiert. Typ C, „Die Pragmatischen“, befindet sich in einem Dilemma, weil die Orientierung zu helfen aufgrund der administrativen Gegebenheiten nicht umgesetzt werden kann. Typ D, „Die Empathischen“, zeigt sich sehr emotionalisiert und lehnt einen vorurteilsbeladenen Mehrheitsdiskurs ab. Jugendliche dieses Typs sehen als Lösung für die gelungene Aufnahme Geflüchteter Empathie und Perspektivübernahme. In den Gruppendiskussionen werden, im Gegensatz zu den Texten, zudem die erfahrungsbasierten Wissensbestände deutlich. Sie lassen sich systematisieren in Medien, Verknüpfung mit der eigenen Identität als Jugendlicher mit Migrationshintergrund, persönlicher Kontakt, Schule, Politikunterricht, Narrativ und Familie., The conception of the research topic results from the overlap of various assumptions that are of equal importance: student perceptions, political values, and value judgments. Political values are didactically relevant as experience-based student perceptions. They are not understood as explicit attitudes, but rather as implicit knowledge. The political value judgment, however, exists on an explicit level (Bohnsack 2010), and values are understood as part of the value judgment. Research on political value judgments at an implicit level is primarily a desideratum in civic education (Petrik 2011, p. 71). Reconstructing political values using the documentary method, this dissertation continues the research of Schelle (1995), Asbrand (2009), Thormann (2012), Petrik (2013), and Winckler (2017). Research questions I. How do students behave in group discussions and individual work when given a value judgment task? II. Which implicit values can be reconstructed from their judgments? How do explicit value judgments and implicit values relate to each other? III. What kind of existing knowledge do the students use to work on these tasks? Research design In this research project 36 student texts were evaluated and five group discussions were conducted at high schools (Gymnasien) in North Rhine-Westphalia, which were analyzed with the documentary method (cf. Bohnsack 2014) and subsequently triangulated (cf. Helsper et al. 2013). In this regard, one stimulus was chosen in reference to the Entscheidungsurteil (decision judgment) (Detjen 2013). Results The study provides insights into the connection of (everyday) experiences and the subjective examination of a political value judgment question. Three meta types of judgment values on the explicit knowledge level as well as four documentary types of implicit judgment values could be derived from the student texts. The value judgments on an expressive level are based on the judgment criteria of effectiveness and legitimacy (Massing 2003), which is an expression of the performance dimension of a school practice. Four types of values could be reconstructed on an implicit level: Type A, “the defensive“, circles the problem and shows a hostile attitude towards refugees. Type B, “the objective“, is orientated towards an inherent necessity logic and understands political actions as pre-structured. Type C, “the pragmatic“, faces a dilemma, as their willingness to help is prevented by administrative circumstances. Type D, “the empathic“, is very emotionalized and rejects the prejudicial discourse of the majority. Adolescents of this type understand empathy and perspective-taking as the requirement for a successful intake of refugees. In contrast to the student texts, the group discussions also reveal experience-based knowledge. This knowledge base can be categorized in media, linked with the own identity as an adolescent with an immigration background, personal contacts, school, political education, narratives, and family.

- Abstract
The different pathologies of an administrative provision reverberate in the context of the configuration of the criminal case. The pathology of the administrative act presents critical profiles that relate to the controversial relationship between non-existence, annulability and nullity, as well as the consequences deriving from the non-total overlap between invalidity and ineffectiveness. The present research aims at identifying which role the administrative provision - accomplished by the public employee - performs in the configuration of the crimes of corruption, for the exercise of the function, bribery and undue induction to give or promise benefits as introduced or modified by the Law 190 of 2012, and what is the legal qualification of its pathology.

COronaVIrus Disease-2019 (COVID-19) is a pandemic respiratory infection caused by a new betacoronavirus, the Severe Acute Respiratory Syndrome-CoronaVirus-2 (SARS-CoV-2). Few data are reported on the gut microbiota in COVID-19 patients. 16S rRNA gene sequencing was performed to reveal an altered composition of the gut microbiota in patients with COVID-19 pneumonia admitted in intensive care unit (ICU) (i-COVID19), or in infectious disease wards (w-COVID19) as compared to controls (CTRL). i-COVID19 patients showed a decrease of Chao1 index as compared to CTRL and w-COVID19 patients indicating that patients in ICU displayed a lower microbial richness while no change was observed as for Shannon Index. At the phylum level, an increase of Proteobacteria was detected in w-COVID19 patients as compared to CTRL. A decrease of Fusobacteria and Spirochetes has been found, with the latter decreased in i-COVID19 patients as compared to CTRL. Significant changes in gut microbial communities in patients with COVID-19 pneumonia with different disease severity compared to CTRL have been identified. Our preliminary data may provide valuable information and promising biomarkers for the diagnosis of the disease and, when validated in larger cohort, it could facilitate the stratification of patients based on the microbial signature.

Research shows that Escherichia coli flavohemoglobin binds to liposomes prepared from lipid extracts of E. coli membranes. Results reveal that protein bound lipids not only affect the binding properties of imidazole to the ferric protein but also modify the reactivity of the ferrous protein with oxygen and carbon monoxide. Data indicate that these effects are due to the involvement of heme iron and a non-heme site in the lipid/ligand recognition.

2011 - 2012, The enhancing waste productions, the change in its composition along with the widespread awareness of environmental issues have increased the technical interest towards the implementation of suitable waste management strategies. Aim of these strategies is the minimization of waste amount and hazardousness as well as the identification of correct treatment and disposal systems, reducing the environmental impact and enhancing the recovery of materials and energy. The implementation of an integrated waste management system represents the most suitable option to enhance waste recovery, thus reducing landfill disposal. In this context, the characterization of the materials subjected to recovery activities is a fundamental phase, because of the potential health and environmental risk connected to the reintroduction, in the cycle of matter, of waste substances, which are potentially harmful. Into consideration of these problems, the research was aimed at: identifying innovative methods for material recovery from waste; studying and promoting the implementation of the most appropriate characterization procedures, in order to minimize the risk associated with the products of recovery activities. According to the different characteristics of waste, the experimental activity was carried out with reference to two different matrixes: a source sorted cellulosic material; an organic fraction coming from the mechanical selection of unsorted waste. The identification of non-conventional recovery solutions is, indeed, particularly interesting, for both cellulosic material and mechanically sorted organic waste. In the former case, the reason is related to the uncertain prospects of the pulp market, so that its use for litter production was proposed. On the other hand, the possible use of the mechanically selected organic fraction represents one of the most important issues due to the its high content of impurities, which limits its recovery. For this matrix, the use as landfill daily cover material was proposed. [edited by author], XI n.s.

Although current trends address towards prevention strategies, the organic fraction of municipal solid waste is greatly produced, especially in high-income contexts. Its recovery-oriented collection is a common practice, but a relevant portion of the biodegradable waste is not source selected. Mechanical and biological treatments (MBT) are the most common option to sort and stabilize the biodegradable matter ending in residual waste stream. Following the changes of the framework around waste management, this paper aimed at analyzing the quality of the mechanically selected organic waste produced in MBT plants, in order to discuss its recovery options. The material performance was obtained by its composition as well as by its main chemical and physical parameters; biological stability was also assessed by both aerobic and anaerobic methods. On this basis, the effectiveness of an aerobic biostabilization process was assessed at pilot scale. After 21 days of treatment, results proved that the biomass had reached an acceptable biostabilization level, with a potential Dynamic Respirometric Index (DRI) value lower than the limit required for its use as daily or final landfill cover material. However, the final stabilization level was seen to be influenced by scaling factors and the 21 days of treatment turned to be not so adequate when applied in the existing full-scale facility.

BACKGROUND: A typical approach for removing As from drinking water includes a pre-oxidation step to transform the more toxic As(III) to As(V) and a subsequent separation process for As(V) removal. Unfortunately, typical oxidants result in the formation of toxic oxidation by-products, so alternative options, such as TiO
2 photocatalysis, have been investigated. But As(V) produced by oxidation of As (III) remains adsorbed on the catalyst surface, thus limiting process efficiency. In this work a new catalyst based on molybdenum oxide supported on titania (MoOx /TiO2 ) was investigated to overcome this drawback. RESULTS: The complete photocatalytic oxidation of As(III) (5 mg L-1 ) to As(V) took place after 120 min exposure to UV-A light. Moreover, the removal of As(V) by adsorption treatment downstream of the photocatalytic process was more effective (90% by γ-Al2 O3 after 10 min) compared with the combined photocatalysis-adsorption process. Finally, the experimental set-up with UV LED irradiation was found to be more effective (96% As(III) converted) than the UV-A light system (75% As(III) converted). CONCLUSION: Photocatalytst did not adsorb As(V) which was completely released into the solution, thus preserving its surface activity and, consequently, drastically reducing operating costs related to catalyst reactivation.

The large size and complex polyploid nature of many genomes has often hampered genomics development, as is the case for several plants of high agronomic value. Isolating single chromosomes or chromosome arms via flow sorting offers a clue to resolve such complexity by focusing sequencing to a discrete and self-consistent part of the whole genome. The occurrence of sufficient differences in the size and or base-pair composition of the individual chromosomes, which is uncommon in plants, is critical for the success of flow sorting. We overcome this limitation by developing a robust method for labeling isolated chromosomes, named Fluorescent In situ Hybridization In suspension (FISHIS). FISHIS employs fluorescently labeled synthetic repetitive DNA probes, which are hybridized, in a wash-less procedure, to chromosomes in suspension following DNA alkaline denaturation. All typical A, B and D genomes of wheat, as well as individual chromosomes from pasta (T. durum L.) and bread (T. aestivum L.) wheat, were flow-sorted, after FISHIS, at high purity. For the first time in eukaryotes, each individual chromosome of a diploid organism, Dasypyrum villosum (L.) Candargy, was flow-sorted regardless of its size or base-pair related content. FISHIS-based chromosome sorting is a powerful and innovative flow cytogenetic tool which can develop new genomic resources from each plant species, where microsatellite DNA probes are available and high quality chromosome suspensions could be produced. The joining of FISHIS labeling and flow sorting with the Next Generation Sequencing methodology will enforce genomics for more species, and by this mightier chromosome approach it will be possible to increase our knowledge about structure, evolution and function of plant genome to be used for crop improvement. It is also anticipated that this technique could contribute to analyze and sort animal chromosomes with peculiar cytogenetic abnormalities, such as copy number variations or cytogenetic aberrations.

(1) Background: COVID-19 is a novel cause of acute respiratory distress syndrome (ARDS). Indeed, with the increase of ARDS cases due to the COVID-19 pandemic, there has also been an increase in the incidence of cases with pneumothorax (PNX) and pneumomediastinum (PNM). However, the incidence and the predictors of PNX/PMN in these patients are currently unclear and even conflicting. (2) Methods: The present observational study analyzed the incidence of barotrauma (PNX/PNM) in COVID-19 patients with moderate–severe ARDS hospitalized in a year of the pandemic, also focusing on the three waves occurring during the year, and treated with positive-pressure ventilation (PPV). We collected demographic and clinical data. (3) Results: During this period, 40 patients developed PNX/PNM. The overall incidence of barotrauma in all COVID-19 patients hospitalized in a year was 1.6%, and in those with moderate–severe ARDS in PPV was 7.2% and 3.8 events per 1000 positive-pressure ventilator days. The incidence of barotrauma in moderate–severe ARDS COVID-19 patients during the three waves was 7.8%, 7.4%, and 8.7%, respectively. Treatment with noninvasive respiratory support alone was associated with an incidence of barotrauma of 9.1% and 2.6 events per 1000 noninvasive ventilator days, of which 95% were admitted to the ICU after the event, due to a worsening of respiratory parameters. The incidence of barotrauma of ICU COVID-19 patients in invasive ventilation over a year was 5.8% and 2.7 events per 1000 invasive ventilator days. There was no significant difference in demographics and clinical features between the barotrauma and non-barotrauma group. The mortality was higher in the barotrauma group (17 patients died, 47.2%) than in the non-barotrauma group (170 patients died, 37%), although this difference was not statistically significant (p = 0.429). (4) Conclusions: The incidence of PNX/PNM in moderate–severe ARDS COVID-19 patients did not differ significantly between the three waves over a year, and does not appear to be very different from that in ARDS patients in the pre-COVID era. The barotrauma does not appear to significantly increase mortality in COVID-19 patients with moderate–severe ARDS if protective ventilation strategies are applied. Attention should be paid to the risk of barotrauma in COVID-19 patients in noninvasive ventilation because the event increases the probability of admission to the intensive care unit (ICU) and intubation.

Most patients infected with SARS-CoV-2 display mild symptoms with good prognosis, while 20% of patients suffer from severe viral pneumonia and up to 5% may require intensive care unit (ICU) admission due to severe acute respiratory syndrome, which could be accompanied by multiorgan failure.Plasma proteomics provide valuable and unbiased information about disease progression and therapeutic candidates. Recent proteomic studies have identified molecular changes in plasma of COVID-19 patients that implied significant dysregulation of several aspects of the inflammatory response accompanied by a general metabolic suppression. However, which of these plasma alterations are associated with disease severity remains only partly characterized.A known limitation of proteomic studies of plasma samples is the large difference in the macromolecule abundance, with concentration spanning at least 10 orders of magnitude. To improve the coverage of plasma contents, we performed a deep proteomic analysis of plasma from 10 COVID-19 patients with severe/fatal pneumonia compared to 10 COVID-19 patients with pneumonia who did not require ICU admission (non-ICU). To this aim, plasma samples were first depleted of the most abundant proteins, trypsin digested and peptides subjected to a high pH reversed-phase peptide fractionation before LC–MS analysis.These results highlighted an increase of proteins involved in neutrophil and platelet activity and acute phase response, which is significantly higher in severe/fatal COVID-19 patients when compared to non-ICU ones. Importantly, these changes are associated with a selective induction of complement cascade factors in severe/fatal COVID-19 patients. Data are available via ProteomeXchange with identifier PXD036491. Among these alterations, we confirmed by ELISA that higher levels of the neutrophil granule proteins DEFA3 and LCN2 are present in COVID-19 patients requiring ICU admission when compared to non-ICU and healthy donors.Altogether, our study provided an in-depth view of plasma proteome changes that occur in COVID-19 patients in relation to disease severity, which can be helpful to identify therapeutic strategies to improve the disease outcome.

Dasypyrum villosum (L.) Candargy (sin. Haynaldia villosa) is an annual wild diploid grass species (2n = 2x = 14; genome VV) belonging to the Poaceae family, which is considered to be an important source of biotic and abiotic stress resistance genes for wheat breeding. Enhanced characterization of D. villosum chromosomes can facilitate exploitation of its gene pool and its use in wheat breeding programs. Here we present the cytogenetic identification of D. villosum chromosomes on slide by fluorescent in situ hybridization (FISH), with the GAA simple sequence repeat (SSR) as a probe. We also describe the isolation and the flow cytometric analysis of D. villosum chromosomes in suspension, resulting in a distinguished flow karyotype. Chromosomes were flow sorted into three fractions, according their DNA content, one of which was composed of a single type of chromosome, namely 6 V, sorted with over 85% purity. Chromosome 6 V is known to carry genes to code for important resistance and seed storage characteristics, and its isolation represents a new source of genetic traits and specific markers useful for wheat improvement.

- Abstract
The x-ray structure of ferric unliganded lipid-free Escherichia coli flavohemoglobin has been solved to a resolution of 2.2 A and refined to an R-factor of 19%. The overall fold is similar to that of ferrous lipid-bound Alcaligenes eutrophus flavohemoglobin with the notable exception of the E helix positioning within the globin domain and a rotation of the NAD binding module with respect to the FAD-binding domain accompanied by a substantial rearrangement of the C-terminal region. An inspection of the heme environment in E. coli flavohemoglobin reveals an unexpected architecture of the distal pocket. In fact, the distal site is occupied by the isopropyl side chain Leu-E11 that shields the heme iron from the residues in the topological positions predicted to interact with heme iron-bound ligands, namely Tyr-B10 and Gln-E7, and stabilizes a pentacoordinate ferric iron species. Ligand binding properties are consistent with the presence of a pentacoordinate species in solution as indicated by a very fast second order combination rates with imidazole and azide. Surprisingly, imidazole, cyanide, and azide binding profiles at equilibrium are not accounted for by a single site titration curve but are biphasic and strongly suggest the presence of two distinct conformers within the liganded species.
