Actitud de los adolescentes hacia la discapacidad
Authors: López Andrea 
Published: July 2023

El objetivo de este proyecto es evaluar las actitudes hacia la discapacidad física y cognitiva con una muestra de 145 adolescentes de la comuna de Puente Alto, en Santiago de Chile, de manera que permita dar cuenta si las actitudes que se presentan en estas edades constituyen un factor que influye negativamente en la inclusión de las personas con discapacidad. Para tal efecto, se validó un instrumento que considera la incorporación de reactivos que miden los distintos componentes actitudinales (cognitivo, afectivo y tendencial) que conforman la actitud hacia la discapacidad, tanto física como intelectual. El instrumento quedó conformado por 36 ítems después de la validación de contenido y la medición de la confiabilidad de consistencia interna para tener una misma proporción de reactivos. Entre los componentes de la actitud, se consideraron 12 por cada componente actitudinal, incluyendo 6 reactivos para la discapacidad física y 6 para la discapacidad cognitiva. Así el instrumento final queda configurado con la misma cantidad de reactivos para cada componente. Después de la validación y aplicación del instrumento, se pudo concluir que hay un grado de consistencia entre los tres componentes que confluyen en una direccionalidad positiva general, con intensidad altamente positiva y una estabilidad en la actitud de los adolescentes hacia la discapacidad. Esta afirmación se apoya en el índice de confiabilidad que posee el instrumento con un valor Alfa de 0.869, demostrando ser un instrumento de medición confiable ya que se acerca al puntaje esperado que es 1.
Anksioznost v peripartalnem obdobju
Authors: Rus Prelog Polona , Rus Makovec Maja 
Published: July 2023

Nosečnost je za ženske občutljivo obdobje, ki ga spremljajo pomembne fiziološke in psihološke spremembe, tako na čustveni kot biološki, hormonski ravni. Anksioznost je v obdobju tako velikih sprememb do neke mere normalen in prilagoditven odgovor na situacijo, vendar pa nekatere nosečnice izkusijo visoko raven anksioznosti, ki doseže stopnjo klinično pomembne motnje. Anksiozne motnje, ki se v peripartalnem obdobju najpogosteje pojavljajo, so generalizirana anksiozna motnja, panična motnja, fobije, obsesivno kompulzivna motnja in posttravmatska stresna motnja. Pretekla anamneza razpoloženjskih in/ali anksioznih motenj je med najmočnejšimi napovedovalci razvoja peripartalne anksioznosti. Kljub temu, da raziskovalno zanimanje za anksiozne motnje v peripartalnem obdobju narašča in vemo več o značilnostih in diagnostiki, pa so dokazi o klinični obravnavi – tako farmakološki kot nefarmakološki - še vedno omejeni. Tveganje in korist uvedbe farmakološkega zdravljenja vedno individualno pretehtamo. Prepoznava in obravnava anksioznosti med nosečnostjo sta bistvenega pomena in delujeta kot preventiva psihiatričnim motnjam po porodu. Poporodna anksioznost matere lahko tudi pomembno ovira proces navezovanja matere in otroka, kar ima posredno tudi vpliv na razvoj otroka. Pri nosečnicah, ki pa so v psihiatrično obravnavo že vključene zaradi obravnavane duševne motnje, pa je sledenje, podpora in dobro interdisciplinarno sodelovanje lečečega psihiatra in ginekološke službe nujno potrebno.
Exploring randomness in autism
Authors: Mantas Vasileios , Kotoula Vasileia , Pehlivanidis Artemios 
Published: July 2023

Introduction
The fast, intuitive and autonomous system 1 along with the slow, analytical and more logical system 2 constitute the dual system processing model of decision making. Whether acting independently or influencing each other both systems would, to an extent, rely on randomness in order to reach a decision. The role of randomness, however, would be more pronounced when arbitrary choices need to be made, typically engaging system 1. The present exploratory study aims to capture the expression of a possible innate randomness mechanism, as proposed by the authors, by trying to isolate system 1 and examine arbitrary decision making in autistic participants with high functioning Autism Spectrum Disorders (ASD).

Methods
Autistic participants withhigh functioning ASD and an age and gender matched comparison group performed the random number generation task. The task was modified to limit the contribution of working memory and allow any innate randomness mechanisms expressed through system 1, to emerge.

Results
Utilizing a standard analyses approach, the random number sequences produced by autistic individuals and the comparison group did not differ in their randomness characteristics. No significant differences were identified when the sequences were examined using a moving window approach. When machine learning was used, random sequences’ features could discriminate the groups with relatively high accuracy.

Conclusions
Our findings indicate the possibility that individual patterns during random sequence production could be consistent enough between groups to allow for an accurate discrimination between the autistic and the comparison group. In order to draw firm conclusions around innate randomness and further validate our experiment, our findings need to be replicated in a bigger sample.

O estudo apresentado neste trabalho teve como objetivo analisar o desempenho da utilização do algoritmo de aprendizado de máquina Naive Bayes para previsão do movimento dos preços das ações que compõem o Índice Ibovespa do mercado de capitais brasileiro (B3 – Brasil, Bolsa, Balcão). Para alcançar o objetivo proposto, foram coletados dados diários dos preços das ações, com participação superior a 1% na carteira teórica do Índice Ibovespa, e calculados indicadores técnicos no período de janeiro de 2012 a dezembro de 2021. Os resultados evidenciaram que os modelos desenvolvidos a partir do algoritmo Naive Bayes obtiveram um desempenho estatisticamente superior à média de mercado. Desse modo, o emprego desse algoritmo de aprendizado de máquina supera o retorno médio esperado com base em dados passados, questionando-se a eficiência desses mercados na forma fraca da hipótese de mercados eficientes (HME). A pesquisa realizada contribui para a literatura das finanças e a prática no mercado de capitais sobre o uso de algoritmos de aprendizado de máquina (especialmente, o Naive Bayes) para previsão do movimento dos preços de ativos listados no mercado brasileiro sob diferentes perspectivas: (i) o estudo acerca da predição dos movimentos diários dos principais ativos do Ibovespa; (ii) a evidenciação de que os desempenhos dos diferentes grupos de indicadores técnicos utilizados não apresentaram diferenças significantes; e (iii) o questionamento da eficiência dos mercados estudados em sua forma fraca em um contexto de ampla automatização por algoritmos de aprendizagem de máquina.

A field trial was conducted at Krishi Vigyan Kendra Dibrugarh, Assam Agricultural University (AAU) to study the production performance of local potato cultivar under different farming practices viz natural, organic and conventional farming during rabi season of 2022-2023. The results revealed that significant increase in growth, yield attributes and yield of local potato was observed in organic farming followed by conventional and natural farming. Growth character of potato like plant height both in vegetative (22cm) as well as reproductive stage (28cm) was found higher in organic farming as compared to conventional and natural farming. Results also indicated that the yield attributing characters like number of tuber plant-1 and average individual tuber weight were significantly higher in organic (4.91g and 9.1 nos) practices followed by conventional (4.49g and 9 nos ) and natural farming practices (4.65g and 8.3 nos). Organic practice resulted better yield of local potato (107.23 q ha-1) as compared to conventional (92.94 q ha-1) and natural farming (88.77q ha-1) practices. The net economic return was also significantly higher in organic practice (222.83000 Rs. ha-1) in comparison to conventional (161.85000 Rs. ha-1) and natural farming (141.33000 Rs. ha-1) practices with more B:C ratio in organic practice (1:2.08).

Authors: Freed Gary L. , Wickham Kyle 
Published: July 2023

BackgroundPrevious comparisons of potential lifetime earnings between general pediatricians and pediatric subspecialties have demonstrated that many subspecialties have lower potential lifetime earnings than general pediatrics. However, those studies selectively used specific data sources for different portions of analyses.ObjectiveTo assess the presence and magnitude of differences in earning forecasts using different authoritative data sources.MethodsThis quality improvement study analyzed compensation data for 14 pediatric subspecialties and general pediatrics from the Association of Administrators in Academic Pediatrics (AAAP), Association of American Medical Colleges (AAMC), and Medical Group Management Association (MGMA) for the 2021 to 2022 academic year.Main Outcomes and MeasuresThe potential lifetime compensation was calculated using the net present value (NPV), which accounts both for compensation throughout training (residency and fellowship) and compensation after graduation. The potential lifetime compensation for the subspecialties and general pediatrics was compared separately for each data source.ResultsThis study included data from 3 sources about 14 subspecialties and general pediatrics. Depending on the data source, the magnitude of the difference in lifetime earnings between subspecialties and general pediatrics varied greatly. For all sources, there was a greater difference in lifetime earnings between higher- and lower-paid subspecialties compared with each other relative to general pediatrics. For the AAAP, the subspecialty with the greatest lifetime NPV is neonatal medicine, and the subspecialty with the least lifetime NPV is endocrinology, with a difference of $2 787 539. For the AAMC, cardiology has the greatest lifetime NPV and endocrinology the least, with a difference of $3 557 492. For the MGMA, neonatal medicine has the greatest lifetime NPV and adolescent medicine the least, with a difference of $4 210 477. Additionally, there is a notable difference in lifetime earnings in private vs academic practice.Conclusions and RelevanceThese findings suggest that the difference in lifetime compensation between many pediatric subspecialties and general pediatrics is not as large as previously reported. Also, greater differences exist when comparing private practice vs academic medicine and between higher- and lower-paid subspecialties.
Phosphorylation by CIPK23 regulates the high‐affinity Mn transporter NRAMP1 in Arabidopsis

Published: July 2023

Manganese (Mn) is essential for plants but is toxic when taken up in excess. To maintain Mn homeostasis, the root Mn transporter natural resistance associated macrophage protein 1 (NRAMP1) cycles from the plasma membrane to endosomes upon phosphorylation. To identify the kinase involved, a split‐luciferase screening was carried out between NRAMP1 and kinases of the CIPK family and identified CIPK23 as a partner of NRAMP1. The interaction was confirmed by split‐mCitrine bimolecular fluorescence complementation and co‐immunoprecipitation assays. In vitro phosphorylation assays pinpointed two CIPK23 target residues in NRAMP1, among which serine 20, important for endocytosis. Interestingly, Mn‐induced internalization of NRAMP1 was unaffected by cipk23 mutation suggesting a potential redundancy between CIPK23 and other kinase(s). How CIPK23 could regulate NRAMP1 in response to Mn availability is discussed.
Sepals
Authors: Roeder Adrienne HK 
Published: July 2023

Abstract

Sepals are the outermost organs of a flower. They are sterile and generally green leaf‐like organs that surround and protect the developing reproductive structures inside the bud before the flower blooms. The sepals are the first organs initiated from the floral meristem and quickly grow to cover the floral meristem and initiating organ primordia. The sepals and petals in the flower interact with the environment by both attracting pollinators as well as defending against predators and abiotic factors such as the weather. Sepal organ identity is specified by the A function in the ABC model.
Arabidopsis
sepals are a model system for investigating morphogenesis (development of organ size and shape) and patterning (differentiation of specialised cell types such as giant cells). Current and future research on the development of sepals is leading to a better understanding of floral organ formation as well as underlying principles of cell division and growth.

Key Concepts

Sepals are the outermost floral organs, which are typically green leaf‐like organs that enclose and protect the developing flower bud before blooming.

Sepals are thought to have evolved from leaves.

Sepal organ identity is specified by A and E function in the ABC model of floral organ identity, and A function is specified by AP1/CAL/FUL clade MADS domain transcription factors, AP2 domain family transcription factors and microRNAs.

The sepal is a commonly studied in
Arabidopsis
to discover fundamental principles of morphogenesis, such as how plant organs grow to reach the right size and shape.

Arabidopsis
sepals are the first floral organs to initiate on the flanks of the floral meristem where they quickly grow to cover and protect the developing reproductive organs, keep the bud closed until blooming and senesce and abscise after the fruit is fertilised.

A scattered pattern of giant cells forms in between smaller cells in the outer epidermis of
Arabidopsis
sepals.

The
Arabidopsis thaliana
MERISTEM LAYER1 (ATML1) transcription factor concentration fluctuates in epidermal cells of the developing sepal; if ATML1 reaches a high concentration during G2 phase of the cell cycle, the cell becomes giant.

Giant cells become enlarged through endoreplication (also known as endoreduplication), during which a cell replicates its DNA and grows without division, becoming highly enlarged and polyploid.

Sepal size and shape are highly reproducible; synchronous timing of both the initiation of sepal primordia and their maturation and cessation of growth are required for all four sepals in the
Arabidopsis
flower to maintain the same size to enclose the flower bud.

The growth and division of sepal cells are highly variable, and gene expression is stochastic; however, sepals maintain robust size and shape through spatiotemporal averaging of growth variability and suppression of gene expression noise by the Paf1C complex.

AbstractButyrate is a key bacterial metabolite that plays an important and complex role in modulation of immunity and maintenance of epithelial barriers. Its translation to clinic is limited by poor bioavailability, pungent smell, and the need for high doses, and effective delivery strategies have yet to realize clinical potential. Here, a novel polymeric delivery platform for tunable and sustainable release of butyrate consisting of a methacrylamide backbone with butyryl ester or phenyl ester side chains as well as mannosyl side chains, which is also applicable to other therapeutically relevant metabolites is reported. This platform's utility in the treatment of non‐healing diabetic wounds is explored. This butyrate‐containing material modulated immune cell activation in vitro and induced striking changes in the milieu of soluble cytokine and chemokine signals present within the diabetic wound microenvironment in vivo. This novel therapy shows efficacy in the treatment of non‐healing wounds through the modulation of the soluble signals present within the wound, and importantly accommodates the critical temporal regulation associated with the wound healing process. Currently, the few therapies to address non‐healing wounds demonstrate limited efficacy. This novel platform is positioned to address this large unmet clinical need and improve the closure of otherwise non‐healing wounds.
Zwitterionic Granular Hydrogel for Cartilage Tissue Engineering

Published: July 2023

AbstractZwitterionic hydrogels have high potential for cartilage tissue engineering due to their ultra‐hydrophilicity, nonimmunogenicity, and superior antifouling properties. However, their application in this field has been limited so far, due to the lack of injectable zwitterionic hydrogels that allow for encapsulation of cells in a biocompatible manner. Herein, a novel strategy is developed to engineer cartilage employing zwitterionic granular hydrogels that are injectable, self‐healing, in situ crosslinkable and allow for direct encapsulation of cells with biocompatibility. The granular hydrogel is produced by mechanical fragmentation of bulk photocrosslinked hydrogels made of zwitterionic carboxybetaine acrylamide (CBAA), or a mixture of CBAA and zwitterionic sulfobetaine methacrylate (SBMA). The produced microgels are enzymatically crosslinkable using horseradish peroxidase, to quickly stabilize the construct, resulting in a microporous hydrogel. Encapsulated human primary chondrocytes are highly viable and able to proliferate, migrate, and produce cartilaginous extracellular matrix (ECM) in the zwitterionic granular hydrogel. It is also shown that by increasing hydrogel porosity and incorporation of SBMA, cell proliferation and ECM secretion are further improved. This strategy is a simple and scalable method, which has high potential for expanding the versatility and application of zwitterionic hydrogels for diverse tissue engineering applications.

AbstractAs an emerging 2D ultrawide bandgap semiconductor, hexagonal boron nitride (h‐BN) is gaining significant attention for its superior properties and wide applications. Although optical properties of h‐BN have been partially revealed by using h‐BN bulk single crystal, luminescence properties of the h‐BN few‐layer are rare due to its poor crystallinity. In this work, the h‐BN epilayers have been synthesized on sapphire substrates by the submicron‐spacing vapor deposition method. The crystalline quality of the h‐BN epilayer is improved with the increase of the growth temperature, and the full width at half‐maximum of the Raman peak is only ≈13 cm−1. The low temperature cathodoluminescence spectra of h‐BN epilayers exhibit two strong deep ultraviolet (DUV) luminescence peaks at 5.49 and 5.35 eV, as well as a weaker and broader defect‐related emission band at ≈4.0 eV. The DUV emission band is ascribed to the recombination of bound excitons and its phonon replica. Based on the theoretically predicted energy levels, the 4.0 eV emission band is tentatively attributed to the radiative transition from C impurities occupying the B sites to the B vacancies. Moreover, the h‐BN‐based DUV photodetectors exhibit an outstanding performance, making it a promising prospect for optoelectronic applications.

AbstractThe catalytic performance of metal–organic frameworks (MOFs) in Li‐S batteries is significantly hindered by unsuitable pore size, low conductivity, and large steric contact hindrance between the catalytic site and lithium polysulfide (LPSs). Herein, the smallest π‐conjugated hexaaminobenzene (HAB) as linker and Ni(II) ions as skeletal node are in situ assembled into high crystallinity Ni‐HAB 2D conductive MOFs with dense Ni‐N4 units via dsp2 hybridization on the surface of carbon nanotube (CNT), fabricating Ni‐HAB@CNT as separator modified layer in Li‐S batteries. As‐obtained unique π‐d conjugated Ni‐HAB nanostructure features ordered micropores with suitable pore size (≈8 Å) induced by HAB ligands, which can cooperate with dense Ni‐N4 chemisorption sites to effectively suppress the shuttle effect. Meanwhile, the conversion kinetics of LPSs is significantly accelerated owing to the small steric contact hindrance and increased delocalized electron density endued by the planar tetracoordinate structure. Consequently, the Li‐S battery with Ni‐HAB@CNT modified separator achieves an areal capacity of 6.29 mAh cm−2 at high sulfur loading of 6.5 mg cm−2 under electrolyte/sulfur ratio of 5 µL mg−1. Moreover, Li‐S single‐electrode pouch cells with modified separators deliver a high reversible capacity of 791 mAh g−1 after 50 cycles at 0.1 C with electrolyte/sulfur ratio of 6 µL mg−1.
