Authors: Λιάπης Χρήστος Ιωάννης
Published: April 2023

Η παρούσα έρευνα στοχεύει στη μελέτη της σχέσης ανάμεσα στην Συναισθηματική Νοημοσύνη, στους Μεγάλους Πέντε Παράγοντες της Προσωπικότητας (Συναισθηματική Αστάθεια, Εξωστρέφεια, Προσήνεια, Ευσυνειδησία, Δεκτικότητα στις εμπειρίες) και την Ψυχοκοινωνική Προσαρμογή (συναισθηματικά συμπτώματα, προβλήματα διαγωγής, υπερκινητικότητα/έλλειψη προσοχής, προβλήματα με συνομηλίκους και φιλοκοινωνική συμπεριφορά) στην προεφηβική ηλικία. Για την πραγματοποίηση της μελέτης μελετήθηκαν ερευνητικά πορίσματα από τη διεθνή επιστημονική κοινότητα και πραγματοποιήθηκε έρευνα με δείγμα 204 προεφήβων μαθητών Ε’ και ΣΤ’ δημοτικού (85 αγόρια και 119 κορίτσια), με τη χρήση ερωτηματολογίων αυτοαναφοράς. Μέσα από την σύγκριση των ευρημάτων, ανιχνεύεται ότι τα κορίτσια εμφανίζουν συχνότερα συναισθηματικά συμπτώματα και φιλοκοινωνική συμπεριφορά από τα αγόρια, ενώ τα αγόρια παρουσιάζουν συχνότερα προβλήματα διαγωγής και υπερκινητικότητα/έλλειψη προσοχής. Επιπλέον, εντοπίστηκε θετική συσχέτιση μεταξύ Συναισθηματικής Νοημοσύνη, θετικών χαρακτηριστικών της Προσωπικότητας (Εξωστρέφεια, Προσήνεια, Ευσυνειδησία, Δεκτικότητα στις εμπειρίες) και φιλοκοινωνικής συμπεριφοράς, ενώ επίσης, ανιχνεύθηκε αρνητική σύνδεση της Συναισθηματικής Νοημοσύνης με τη Συναισθηματική Αστάθεια και με τις δυσκολίες προσαρμογής (συναισθηματικά συμπτώματα, προβλήματα διαγωγής, υπερκινητικότητα/έλλειψη προσοχής, προβλήματα με συνομηλίκους). Τα παρακάτω ευρήματα έδειξαν ότι οι δυσκολίες στη Ψυχοκοινωνική Προσαρμογή μπορούν να προβλεφθούν από τη Συναισθηματική Νοημοσύνη και τα χαρακτηριστικά των διαστάσεων της Προσωπικότητας. Ταυτόχρονα, τα ευρήματα της παρούσας έρευνας θα μπορούσαν να αξιοποιηθούν για την ενημέρωση γονέων και εκπαιδευτικών, αλλά και ως έμπνευση για περαιτέρω έρευνα.

Introduction: Laser therapy has been used in medicine for many years. One of the most willingly used is the fractional ablative CO2 laser. As a result of its use, the improvement of pigmentation, skin texture and signs of aging are achieved. Laser therapy owes its popularity to its low invasiveness and good, long-lasting effects of the procedure. Despite its important role in aesthetic medicine, we should not forget about its participation in the treatment of scars, often extensive, causing troublesome symptoms to patients, the source of which is not only a defect of a cosmetic nature.
Purpose of the work: The purpose of the study is to present mechanism of action, assessment of safety,  effectiveness in the treatment and possible side effects based on a review of scientific literature.
Material and methods: The work was based on a review of available medical publications on the use of the fractional ablative CO2 laser. The literature in the PubMed and Google Scholar databases was searched based on the following keywords: fractional ablative CO2 laser, mechanism of action, safety of use, side effects.
Conclusion: The use of a fractional ablative CO2 laser causes the increased collagen production in the dermis. This effect contributes to the elevation of the quantity and level of collagen arrangement, and also to the reduction of the visibility of the effects of photoaging. As a result, the skin in the treated area becomes thicker, and thus firmer. The pigmentation and texture are also being improved. The procedure is relatively slightly invasive, and the side effects are self-limiting in the most cases.
Rosja wobec wymiaru wschodniego Europejskiej Polityki Sąsiedztwa Unii Europejskiej
Authors: Tkachuk Olesia
Published: April 2023

The development of cooperation between the European Union (EU) and six post-Soviet republics (Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine) over the last two decades has evolved from the principles and mechanisms established under the European Neighborhood Policy (ENP) to instruments and processes initiated with the inauguration of the Eastern Partnership programme. However, from the very beginning, the participation of partner countries in both of the above-mentioned EU cooperation proposals was very different. Belarus was not interested in participating in them, and the position of Armenia and Azerbaijan was ambivalent, and thus three countries (Georgia, Moldova and Ukraine) took full advantage of the EU cooperation offer. In particular, they signed Association Agreements with the European Union, including Deep and Comprehensive Free Trade Areas, while committing themselves to internal political, economic and social reforms. In 2022, the prospect of EU membership was opened to them. In reaction to the rapprochement of Georgia, Moldova and Ukraine with the EU, the Russian Federation, treating the post-Soviet area as its own sphere of influence, used instruments such as political, economic and energy pressure, a trade embargo and military force against these countries. On the one hand, the Russian authorities emphasized the sovereign right of each state to develop relations with various partners, while on the other hand, they tried to limit the presence of Western structures in the post-Soviet area. Therefore, Moscow’s position on the ENP and the Eastern Partnership was critical, although initially the EU’s neighborhood policy was treated as a “natural aspiration” of the EU to establish a “forward-looking strategy for relations with the countries surrounding it”. Nevertheless, over time, the ENP, and later also its eastern dimension in the form of the Eastern Partnership, began to be perceived by Russia as a threat to its own national interests, recognizing that their goal is to separate the aforementioned post-Soviet republics from the Russian Federation, and thus to weaken its position in international relations.

Sensitivity Analysis of the Maximal Value Function with Applications in Nonconvex Minimax Programs
Authors: Guo Lei , Ye Jane J. , Zhang Jin
Published: April 2023

In this paper, we perform a sensitivity analysis for the maximal value function, which is the optimal value function for a parametric maximization problem. Our aim is to study various subdifferentials for the maximal value function. We obtain upper estimates of Fréchet, limiting, and horizon subdifferentials of the maximal value function by using some sensitivity analysis techniques sophisticatedly. The derived upper estimates depend only on the union of all solutions and not on its convex hull or only one solution from the solution set. Finally, we apply the derived results to develop some new necessary optimality conditions for nonconvex minimax problems. In the nonconvex-concave setting, our Wolfe duality approach compares favorably with the first-order approach in that the necessary condition is sharper and the constraint qualification is weaker.

A Arte (Moderna) dos Hospícios ou a Ética da “Loucura” no Modernismo Brasileiro
Authors: Rivera Tania
Published: April 2023

Desdobrando as articulações promovidas no contexto inicial do modernismo brasileiro entre artistas de vanguarda e instituições psiquiátricas nacionais, o artigo analisa criticamente a marginalização das produções artísticas realizadas em instituições psiquiátricas na História da Arte Moderna e Contemporânea brasileira. Refletindo na contramão da tendência à patologização e à deslegitimação da arte realizada por artistas ditos "loucos" que serviu enquanto sustentáculo para a marginalização de suas práticas, o texto defende-as enquanto uma das principais vias pelas quais se construiu a modernidade brasileira nas artes.

Les Batutas, 1922: uma antropologia da noite parisiense
Authors: Bastos Rafael José de Menezes
Published: April 2023

Em 1922, Os Batutas passaram seis meses em Paris, tocando em casas noturnas e festas. O grupo era dirigido por Pixinguinha e incluía Donga, autor da música de Pelo Telefone. A viagem é um episódio pouco conhecido da história da música popular brasileira, com fortes conseqüências para a carreira de Pixinguinha e o futuro dessa música. O artigo a vê como etapa fundante no sentido da consagração de Pixinguinha, apontando para a necessidade de compreender a música popular como linguagem estratégica do sistema de relações dos Estados-nações modernos, com nexos locais, regionais, nacionais e globais. Aí, as músicas erudita, folclórica e popular são vistas como universos em comunicação e a fonografia como processo constitutivo de todas. A reconstituição da viagem é feita com base na leitura de jornais franceses e outros textos da época.
A Forma Excessiva da Falta: retórica nacionalista e pensamento plástico
Authors: Siqueira Vera Beatriz
Published: April 2023

Este artigo aborda a questão da definição de arte brasileira, a partir das críticas contemporâneas, no campo da produção artística, à sintetização proposta pelos modernistas por meio da categoria de brasilidade, com todas as suas variantes posteriores, que a aproximavam do civismo. Rediscutir em outro registro o tema (problemático) da identidade nacional nas artes implica na sua compreensão como um dos estratos culturais da obra, em permanente tensão com a requisição de independência e universalidade da experiência estética moderna.

Relation between the row left rank of a quaternion unit gain graph and the rank of its underlying graph
Authors: Zhou Qiannan , Lu Yong
Published: April 2023

Let $\Phi=(G,U(\mathbb{Q}),\varphi)$ be a quaternion unit gain graph (or $U(\mathbb{Q})$-gain graph), where $G$ is the underlying graph of $\Phi$, $U(\mathbb{Q})=\{z\in \mathbb{Q}: |z|=1\}$ is the circle group, and $\varphi:\overrightarrow{E}\rightarrow U(\mathbb{Q})$ is the gain function such that $\varphi(e_{ij})=\varphi(e_{ji})^{-1}=\overline{\varphi(e_{ji})}$. Let $A(\Phi)$ be the adjacency matrix of $\Phi$ and $r(\Phi)$ be the row left rank of $\Phi$. In this paper, we prove that $-2c(G)\leq r(\Phi)-r(G)\leq 2c(G)$, where $r(G)$ and $c(G)$ are the rank and the dimension of cycle space of $G$, respectively. All corresponding extremal graphs are characterized. The results will generalize the corresponding results of signed graphs (Lu et al. [20] and Wang [33]), mixed graphs (Chen et al. [7]), and complex unit gain graphs (Lu et al. [21]).

Aims

To investigate health-related quality of life (HRQoL) of older adults (aged ≥ 60 years) after tibial plateau fracture (TPF) compared to preinjury and population matched values, and what aspects of treatment were most important to patients.

Methods

We undertook a retrospective, case-control study of 67 patients at mean 3.5 years (SD 1.3; 1.3 to 6.1) after TPF (47 patients underwent fixation, and 20 nonoperative management). Patients completed EuroQol five-dimension three-level (EQ-5D-3L) questionnaire, Lower Limb Function Scale (LEFS), and Oxford Knee Scores (OKS) for current and recalled prefracture status. Propensity score matching for age, sex, and deprivation in a 1:5 ratio was performed using patient level data from the Health Survey for England to obtain a control group for HRQoL comparison. The primary outcome was the difference in actual (TPF cohort) and expected (matched control) EQ-5D-3L score after TPF.

Results

TPF patients had a significantly worse EQ-5D-3L utility (mean difference (MD) 0.09, 95% confidence interval (CI) 0.00 to 0.16; p < 0.001) following their injury compared to matched controls, and had a significant deterioration (MD 0.140, 95% CI 0 to 0.309; p < 0.001) relative to their preoperative status. TPF patients had significantly greater pre-fracture EQ-5D-3L scores compared to controls (p = 0.003), specifically in mobility and pain/discomfort domains. A decline in EQ-5D-3L greater than the minimal important change of 0.105 was present in 36/67 TPF patients (53.7%). Following TPF, OKS (MD -7; interquartile range (IQR) -1 to -15) and LEFS (MD -10; IQR -2 to -26) declined significantly (p < 0.001) from pre-fracture levels. Of the 12 elements of fracture care assessed, the most important to patients were getting back to their own home, having a stable knee, and returning to normal function.

Conclusion

TPFs in older adults were associated with a clinically significant deterioration in HRQoL compared to preinjury level and age, sex, and deprivation matched controls for both undisplaced fractures managed nonoperatively and displaced or unstable fractures managed with internal fixation.

SIMPLE INCREMENTAL APPROACH FOR ANALYSING OPTIMAL NON-PRISMATIC FUNCTIONALLY GRADED BEAMS

This paper presents a simple incremental approach of analysing the static behaviour of functionally graded tapered beams. This approach involves dividing the non-uniform beam into segments with uniform cross-sections, and using two separate finite element models to analyse the structural behavior of slender beams (Euler-Bernoulli model) and deep beams (Timoshenko beam theory). The material properties of the beam vary according to a power law distribution through the thickness, resulting in smooth variations in the mechanical properties. The finite element system of equations is obtained using the principle of virtual work. Detailed information on the shape functions and stiffness matrix of the beam is provided, and the numerical results are evaluated and validated using data from the literature. The comparison demonstrates that the response of the functionally graded tapered beams is accurately assessed by the proposed approach. Additionally, the effects of material distribution, boundary conditions, and tapering parameter on the deflection behavior are presented. Results show that an increase in the power law index increases the flexibility of the functionally graded tapered beams, resulting in higher deflection. Furthermore, lower tapering parameters also result in higher deflection. Compared to other boundary conditions, clamped-clamped boundary conditions demonstrate the best performance in terms of maximum deflection.
Art del llenguatge i diversitat lingüística. De R. Jakobson a l. Talmy i É. Glissant
Authors: Fuentes-Calle Alícia
Published: April 2023

Aquesta tesi s’interessa per l’activació poètica del llenguatge com a matèria primera de diverses manifestacions artístiques, al marge del focus estrictament literari. L’objectiu principal és situar l’art del llenguatge en la perspectiva de la diversitat lingüística. Explorem la hipòtesi que les manifestacions de l’art del llenguatge s’articulen al voltant de dos eixos: una dimensió lingüística activada poèticament (locus d’activació) / una ideologia lingüística latent. Un cop detectada la tendència de les manifestacions d’art del llenguatge a inscriure’s en el marc referencial d’un sistema lingüístic únic, situem les consideracions anteriors en la perspectiva de la diversitat lingüística: - (Locus d’activació poètica) Presentem la coevolució dels loci de la funció poètica (referència, dixi, performativitat) amb els loci postulats per la teorització sobre diversitat lingüística; - (Ideologia lingüística) Presentem una breu síntesi històrica de l’aproximació a la diversitat lingüística i intercalem alguns exemples rellevants d’art del llenguatge que se’n deriven. En aquest punt tornem a valorar l’estat de la qüestió i identifiquem quin és el locus activat de manera predominant en l’art del llenguatge en context de diversitat lingüística, i quina concepció del llenguatge (aproximació a la diversitat lingüística) hi ha latent. A partir dels resultats d’aquesta valoració i de la identificació de vies que considerem poc explorades, presentem una proposta heurística en les dues direccions que marquen la recerca: Pel que fa al locus d’activació, proposem l’activació poètica/ cerca de la poètica implícita d’un aparell teòric (Talmy 2000a). Pel que fa a la ideologia lingüística, activem l’aproximació d’Édouard Glissant (“le multilingüisme, un mode de l’imaginaire”). La inclinació per un determinat sentit de la poètica –la poètica implícita- ha deixat fora un espectre molt ampli de manifestacions possibles d’art del llenguatge. La tesi interpreta, en termes heurístics nous, un conjunt de dades i marcs teòrics i aporta hipòtesis i propostes de recerca i creació derivades. En particular: una perspectiva sobre l’art del llenguatge al marge del “prejudici literari”; i la identificació –experimentada en dues vies concretes- de dos paràmetres que articulen les manifestacions d’art del llenguatge.

Aprendre a prendre poesia visual: estratègies i orientacions didàctiques
Authors: Masgrau-Juanola Mariona
Published: April 2023

Aquesta contribució es planteja el potencial didàctic de la poesia visual. Se’n fa una breu revisió historiogràfica que en justifica el valor patrimonial i se sintetitzen algunes aportacions cabdals de la didàctica de la literatura en aquest àmbit. S’exposen cinc tallers de poesia visual; es documenten i se n’analitzen diversos incidents crítics mitjançant les metodologies clíniques, els quals propicien una revisió permanent de les propostes de mediació. Aquest procés reflexiu permet respondre tres preguntes de recerca i esbossar orientacions didàctiques: Quant als objectius i criteris que han de regir la tria de poemes visuals per a llegir amb infants, es considera que s’ha d’optar per un corpus eclèctic en estratègies i figures retòriques, representatiu de diverses èpoques, incloent també la contemporaneïtat. Es planteja si la poesia visual pot propiciar estratègies de lectura necessàries per a d’altres contextos i s’argumenta que potencia habilitats lectores intermedials, metareflexives i crítiques. Quant al foment de la creativitat dels infants, es defensa la necessitat de mantenir el caràcter experimental i disruptiu propi de la poesia visual a l’hora de fer-ne la transposició, per tal que les propostes didàctiques no esdevinguin imitatives. Finalment, s’apunten noves línies d’innovació didàctica.
conversa literària en la formació inicial de mestres. Un cas pràctic a partir de tres clàssics LIJ
Authors: Amat Castells Vanesa
Published: April 2023

Aquest article conté l’anàlisi de tres converses literàries sobre clàssics de la literatura infantil i juvenil en la formació inicial de mestres. L’objectiu principal és conèixer el tipus de respostes lectores dels estudiants-futurs mestres, el seu grau de profunditat, així com la influència de la mediació. Al mateix temps, es vol oferir una proposta que els pugui ser útil, quan exerceixin la seva tasca com a docents, per dur a terme discussions literàries amb infants. Els resultats mostren com les seves respostes inicials són molt emocionals i personals i que són de caràcter més pedagògic que literari. Les converses també fan aflorar aspectes sobre llenguatge, sobre elements com el desenllaç o connexions amb altres ficcions. La tasca de mediació, especialment en la formulació de preguntes, és important perquè apareguin reflexions sobre aspectes literaris. Es confirma la necessitat d’oferir als estudiants espais per intercanviar idees sobre lectures literàries per millorar la seva competència en aquest àmbit.

Source identification and accurate measurements of methane gas
concentration are key tools necessary for climate change management.
Here we present a method for methane isotopologue ratio measurement
using a laser-based frequency modulation (FM) spectroscopy technique
in the near infrared at 1661 nm. We provide line shape analysis
and discuss a fitting algorithm for accurate isotopologue ratio
metrology and investigate and minimize the effects of residual
amplitude modulation on the experimentally produced FM signal line
shape. This FM technique is further evaluated for future development
of a cavity-enhanced and noise-immune system capable of isotopologue
ratio as well as ultrasensitive trace gas measurements, all accessible
using a single distributed feedback laser.
Optical reflection characteristic–based emissivity analysis of a pyramid array flat-plate blackbody for remote sensor calibration
Authors: Wang Gang , Xia Caijuan , Song Jian , Zhou Jingjiing , Sima Ruiheng , Liu Zhiyi , Hao Xiaopeng
Published: April 2023

The flat-plate blackbody (FPB) is the core device in infrared remote sensing radiometric calibration for providing accurate infrared radiation energy. The emissivity of an FPB is an important parameter that directly affects calibration accuracy. This paper uses a pyramid array structure based on the regulated optical reflection characteristics to analyze the FPB’s emissivity quantitatively. The analysis is accomplished by performing emissivity simulations based on the Monte Carlo method. The effects of specular reflection (SR), near-specular reflection (NSR), and diffuse reflection (DR) on the emissivity of an FPB with pyramid arrays are analyzed. In addition, various patterns of normal emissivity, small-angle directional emissivity, and emissivity uniformity are examined under different reflection characteristics. Further, the blackbodies with the NSR and DR are fabricated and tested experimentally. The experimental results show a good agreement with the corresponding simulation results. The emissivity of the FPB with the NSR can reach 0.996 in the 8–14 µm waveband. Finally, the emissivity uniformity of FPB samples at all tested positions and angles is better than 0.005 and 0.002, respectively. The standard uncertainty of experimental measurement of waveband emissivity and spectral emissivity are 0.47% and 0.38% respectively, and the simulation uncertainty is 0.10%.

Chip-based, single-frequency and low phase-noise integrated photonic laser diodes emitting in the violet (412 nm) and blue (461 nm) regime are demonstrated. The GaN-based edge-emitting laser diodes were coupled to high-quality on-chip micro-resonators for optical feedback and mode selection resulting in laser self-injection locking with narrow emission linewidth. Multiple group III-nitride (III-N) based photonic integrated circuit chips with different waveguide designs including single-crystalline AlN, AlGaN, and GaN were developed and characterized. Single-frequency laser operation was demonstrated for all studied waveguide core materials. The best side-mode suppression ratio was determined to be ∼36 dB at 412 nm with a single-frequency laser emission linewidth of only 3.8 MHz at 461 nm. The performance metrics of this novel, to the best of our knowledge, type of laser suggest potential implementation in next-generation, portable quantum systems.

Learning-based phase imaging balances high fidelity and speed. However, supervised training requires unmistakable and large-scale datasets, which are often hard or impossible to obtain. Here, we propose an architecture for real-time phase imaging based on physics-enhanced network and equivariance (PEPI). The measurement consistency and equivariant consistency of physical diffraction images are used to optimize the network parameters and invert the process from a single diffraction pattern. In addition, we propose a regularization method based total variation kernel (TV-K) function constraint to output more texture details and high-frequency information. The results show that PEPI can produce the object phase quickly and accurately, and the proposed learning strategy performs closely to the fully supervised method in the evaluation function. Moreover, the PEPI solution can handle high-frequency details better than the fully supervised method. The reconstruction results validate the robustness and generalization ability of the proposed method. Specially, our results show that PEPI leads to considerable performance improvement on the imaging inverse problem, thereby paving the way for high-precision unsupervised phase imaging.

Genes associated with risk for brain disease exhibit characteristic expression patterns that reflect both anatomical and cell type relationships. Brain-wide transcriptomic patterns of disease risk genes provide a molecular-based signature, based on differential co-expression, that is often unique to that disease. Brain diseases can be compared and aggregated based on the similarity of their signatures which often associates diseases from diverse phenotypic classes. Analysis of 40 common human brain diseases identifies 5 major transcriptional patterns, representing tumor-related, neurodegenerative, psychiatric and substance abuse, and 2 mixed groups of diseases affecting basal ganglia and hypothalamus. Further, for diseases with enriched expression in cortex, single-nucleus data in the middle temporal gyrus (MTG) exhibits a cell type expression gradient separating neurodegenerative, psychiatric, and substance abuse diseases, with unique excitatory cell type expression differentiating psychiatric diseases. Through mapping of homologous cell types between mouse and human, most disease risk genes are found to act in common cell types, while having species-specific expression in those types and preserving similar phenotypic classification within species. These results describe structural and cellular transcriptomic relationships of disease risk genes in the adult brain and provide a molecular-based strategy for classifying and comparing diseases, potentially identifying novel disease relationships.

Down syndrome (DS) is caused by the trisomy of human chromosome 21 (HSA21). A major challenge in DS research is to identify the HSA21 genes that cause specific symptoms. Down syndrome cell adhesion molecule (DSCAM) is encoded by a HSA21 gene. Previous studies have shown that the protein level of the Drosophila homolog of DSCAM determines the size of presynaptic terminals. However, whether the triplication of DSCAM contributes to presynaptic development in DS remains unknown. Here, we show that DSCAM levels regulate GABAergic synapses formed on neocortical pyramidal neurons (PyNs). In the Ts65Dn mouse model for DS, where DSCAM is overexpressed due to DSCAM triplication, GABAergic innervation of PyNs by basket and chandelier interneurons is increased. Genetic normalization of DSCAM expression rescues the excessive GABAergic innervations and the increased inhibition of PyNs. Conversely, loss of DSCAM impairs GABAergic synapse development and function. These findings demonstrate excessive GABAergic innervation and synaptic transmission in the neocortex of DS mouse models and identify DSCAM overexpression as the cause. They also implicate dysregulated DSCAM levels as a potential pathogenic driver in related neurological disorders.
Whole exome sequencing analysis of canine urothelial carcinomas without BRAF V595E mutation: Short in-frame deletions in BRAF and MAP2K1 suggest alternative mechanisms for MAPK pathway disruption

Molecular profiling studies have shown that 85% of canine urothelial carcinomas (UC) harbor an activating BRAF V595E mutation, which is orthologous to the V600E variant found in several human cancer subtypes. In dogs, this mutation provides both a powerful diagnostic marker and a potential therapeutic target; however, due to their relative infrequency, the remaining 15% of cases remain understudied at the molecular level. We performed whole exome sequencing analysis of 28 canine urine sediments exhibiting the characteristic DNA copy number signatures of canine UC, in which the BRAF V595E mutation was undetected (UDV595E specimens). Among these we identified 13 specimens (46%) harboring short in-frame deletions within either BRAF exon 12 (7/28 cases) or MAP2K1 exons 2 or 3 (6/28 cases). Orthologous variants occur in several human cancer subtypes and confer structural changes to the protein product that are predictive of response to different classes of small molecule MAPK pathway inhibitors. DNA damage response and repair genes, and chromatin modifiers were also recurrently mutated in UDV595E specimens, as were genes that are positive predictors of immunotherapy response in human cancers. Our findings suggest that short in-frame deletions within BRAF exon 12 and MAP2K1 exons 2 and 3 in UDV595E cases are alternative MAPK-pathway activating events that may have significant therapeutic implications for selecting first-line treatment for canine UC. We developed a simple, cost-effective capillary electrophoresis genotyping assay for detection of these deletions in parallel with the BRAF V595E mutation. The identification of these deletion events in dogs offers a compelling cross-species platform in which to study the relationship between somatic alteration, protein conformation, and therapeutic sensitivity.

We investigated the residual rate and mass loss rate of litter, as well as the carbon release dynamics of litter and soil across seasons, to better understand the effects of seasonal fluctuations on carbon dynamics in mixed coniferous forests. The study was carried out in natural mixed coniferous forests in the Xiaoxinganling region of Heilongjiang Province, China, and the number of temperature cycles in the unfrozen season, freeze–thaw season, frozen season, and thaw season was controlled. The goal of the study was to examine how the carbon release dynamics of litter and soil respond to the freeze–thaw process and whether there are differences in carbon release dynamics under different seasons. Repeated-measures analysis of variance was used to analyze the residual mass rate and mass loss rate of litter, litter organic carbon and soil organic carbon during the unfrozen season, freeze-thaw season, frozen season, and thaw season. Litter decomposition was highest in the unfrozen season (15.9%~20.3%), and litter and soil carbon were sequestered throughout this process. Temperature swings above and below 0°C during the freeze–thaw season cause the litter to physically fragment and hasten its decomposition. Decomposition of litter was still feasible during the frozen season, and it was at its lowest during the thaw season (7.2%~7.8%), when its organic carbon was transported to the soil. Carbon migrates from undecomposed litter to semi-decomposed litter and then to soil. The carbon in the environment is fixed in the litter (11.3%~18.2%) and soil (34.4%~36.7%) in the unfrozen season, the carbon-fixing ability of the undecomposed litter in the freeze-thaw season is better, and the carbon in the semi-decomposed litter is mostly transferred to the soil; the carbon-fixing ability of the litter in the frozen season is worse (-3.9%~ -4.3%), and the organic carbon in the litter is gradually transferred to the soil. The carbon-fixing ability of the undecomposed litter in the thaw season is stronger, and the organic carbon in the semi-decomposed litter is mostly transferred to the soil. Both litter and soil can store carbon; however, from the unfrozen season until the thaw season, carbon is transported from undecomposed litter to semi-decomposed litter and to the soil over time.
Extending the audiogram with loudness growth: The complementarity of electric and acoustic hearing in bimodal patients

Published: April 2023

Introduction

Clinically, recording hearing detection thresholds and representing them in an audiogram is the most common way of evaluating hearing loss and starting the fitting of hearing devices. As an extension, we present the loudness audiogram, which does not only show auditory thresholds but also visualizes the full course of loudness growth across frequencies. The benefit of this approach was evaluated in subjects who rely on both electric (cochlear implant) and acoustic (hearing aid) hearing.

Methods

In a group of 15 bimodal users, loudness growth was measured with the cochlear implant and hearing aid separately using a loudness scaling procedure. Loudness growth curves were constructed, using a novel loudness function, for each modality and then integrated in a graph plotting frequency, stimulus intensity level, and loudness perception. Bimodal benefit, defined as the difference between wearing a cochlear implant and hearing aid together versus wearing only a cochlear implant, was assessed for multiple speech outcomes.

Results

Loudness growth was related to bimodal benefit for speech recognition in noise and to some aspects of speech quality. No correlations between loudness and speech in quiet were found. Patients who had predominantly unequal loudness input from the hearing aid, gained more bimodal benefit for speech recognition in noise compared to those patients whose hearing aid provided mainly equivalent input.

Conclusion

Results show that loudness growth is related to bimodal benefit for speech recognition in noise and to some aspects of speech quality. Subjects who had different input from the hearing aid compared to CI, generally gained more bimodal benefit compared to those patients whose hearing aid provided mainly equivalent input. This suggests that bimodal fitting to create equal loudness at all frequencies may not always be beneficial for speech recognition.

Lifetime experiences and lifestyle, such as education and engaging in leisure activities, contribute to cognitive reserve (CR), which delays the onset of age-related cognitive decline. Word-finding difficulties have been identified as the most prominent cognitive problem in older age. Whether CR mitigates age-related word-finding difficulties is currently unknown. Using picture-naming and verbal fluency tasks, this online study aimed to investigate the effect of CR on word-finding ability in younger, middle-aged, and older adults. All participants were right-handed, monolingual speakers of British English. CR for both the period preceding and coinciding with the COVID-19 pandemic was measured through years of education and questionnaires concerning the frequency of engagement in cognitive, leisure, and physical activities. Linear mixed-effect models demonstrated that older adults were less accurate at action and object naming than middle-aged and younger adults. Higher CR in middle age predicted higher accuracies for action and object naming. Hence, high CR might not only be beneficial in older age, but also in middle age. This benefit will depend on multiple factors: the underlying cognitive processes, individual general cognitive processing abilities, and whether task demands are high. Moreover, younger and middle-aged adults displayed faster object naming compared to older adults. There were no differences between CR scores for the period preceding and coinciding with the pandemic. However, the effect of the COVID-19 pandemic on CR and, subsequently, on word-finding ability might only become apparent in the long term. This article discusses the implications of CR in healthy ageing as well as suggestions for conducting language production studies online.

Nucleotide Sugar Transporters (NSTs) belong to the SLC35 family (human solute carrier) of membrane transport proteins and are crucial components of the glycosylation machinery. NSTs are localized in the ER and Golgi apparatus membranes, where they accumulate nucleotide sugars from the cytosol for subsequent polysaccharide biosynthesis. Loss of NST function impacts the glycosylation of cell surface molecules. Mutations in NSTs cause several developmental disorders, immune disorders, and increased susceptibility to infection. Atomic resolution structures of three NSTs have provided a blueprint for a detailed molecular interpretation of their biochemical properties. In this work, we have identified, cloned, and expressed 18 members of the SLC35 family from various eukaryotic organisms in Saccharomyces cerevisiae. Out of 18 clones, we determined Vrg4 from Chaetomium thermophilum (CtVrg4) is a GDP-mannose transporter with an enhanced melting point temperature (Tm) of 56.9°C, which increases with the addition of substrates, GMP and GDP-mannose. In addition, we report—for the first time—that the CtVrg4 shows an affinity to bind to phosphatidylinositol lipids.
