Authors: Matuszewska Izabela , Burduk Paweł , Kaźmierczak Wojciech , Janiak-Kiszka Joanna
Published: November 2016

Objective: We reviewed functional outcomes of tympanoplasty.

Study design: The results of tympanoplastic surgery are changing in time. We present late treatment outcomes among different types of tympanoplasty.

Methods: Eighty-six patients who underwent tympanoplasty were enrolled in the study. The results of pure tone audiometry performed 7 days before, then at 3 months, 1 year, and 3 years after the surgery were assessed. Type II tympanoplasty involved implantation of a partial ossicular replacement prosthesis and type III tympanoplasty involved reconstruction with a total ossicular replacement prosthesis and the use of autogenous homogenous material. Statistical analysis was performed.

Results: With all four types of tympanoplasty, hearing improvement was achieved at 3 months and 1 year after surgery based on the magnitude of the mean ABG reduction (p<0.001). In patients who underwent type I, type III, and type IV tympanoplasty, the ABG reduction at 3 years after surgery was maintained at the level reported at 3 months and 1 year after surgery (p<0.001). In patients who underwent type II tympanoplasty, however, the mean ABG value was increased at all tested frequencies (p<0.05). The mean ABG values reported 3 years after type II and type III tympanoplasty were similar.

Conclusions: Based on the results over time, hearing improvement seems to be less durable after reconstruction with the partial ossicular replacement prosthesis procedure compared to the total ossicular replacement prosthesis procedure.

Published: November 2016

INTRODUCTION: Sinonasal inverted papillomas (IPs) are a major challenge for ENT specialists. In the last decades, the number of endoscopic procedures has increased, while the percentage of external or double approach procedures has decreased. The aim of this study was to evaluate long-term IP treatment outcomes according to the applied surgical method. MATERIAL AND METHODS: the retrospective study included 69 patients (28 women and 41 men) treated during 2002–2012 in the Department of Otolaryngology and Laryngological Oncology of Poznań University of Medical Sciences. Of these patients, 47 were operated endoscopically, 16 received a double procedure and six received an external procedure. RESULTS: The recurrence rate in patients treated endoscopically was 32%, while patients treated by the external/double approach showed 64% (p = 0.03306). The recurrence rate after endoscopic surgery was 75% during 2002–2006, but was 28% during 2007–2012. There was no correlation between recurrence rate and age (p = 0.087686), gender (p = 0.42810), type of symptoms (p = 0.20955), or Krouse staging (p = 0.23658). A significant impact on relapses was the position to Ohngren’s plane (p = 0.004768) and tumor location in the anterior ethmoid (p = 0.00416). DISCUSSION: Endoscopic procedures are an effective method of IP treatment, however reasonable indications and surgeon experience should be taken into consideration.

Authors: J. Rzoska Sylwester , Starzonek Szymon , Drozd- Rzoska Aleksandra
Published: November 2016

The impact of nanoparticles on phase transitions in liquid crystal (LC)—nanoparticle nanocollids is still little known. This contribution results for dodecylcyanobiphenyl (12CB), pentylcyanobiphenyl (5CB), and hexyl isothiocyanatobiphenyl (6BT) as the LC host with the addition of BaTiO3 barium titanate barium titanate nanoparticles. The latter has a strong impact on the value of dielectric constant, relaxation time, and the discontinuity of the isotropic–mesophase transitions. The first-ever high-pressure studies in such systems are also presented.
Colloidal Photonic Crystals Containing Copper-Oxide and Silver Nanoparticles with Tunable Structural Colors
Authors: Lai Chun-Feng
Published: November 2016

In this chapter, we investigated polystyrene (PS) colloidal photonic crystal (CPhC) color films containing copper-oxide (CuO) nanoparticles (NPs) and silver (Ag) NPs and exhibiting tunable structural colors. PS CPhC color films containing CuO-NPs and Ag-NPs were prepared through thermal-assisted self-assembly by using a gravitational sedimentation method. Doped CuO-NPs and Ag-NPs deposited on the bottom of the substrate and acted as black materials that absorb background and scattering light. Experimental results showed that brilliant structural colors were enhanced because of the absorption of incoherently scattered light, and color saturation was increased by the distribution of metal NPs on PS CPhC surfaces. The brilliant structural colors of CuO-NPs/PS and Ag-NPs/PS hybrid CPhC color films were based on the scattering absorption and Bragg diffraction theory. The reflection peaks of metal-NPs/PS hybrid CPhCs and pure PS CPhCs were measured by UV-Visible reflection spectrometry and theoretically calculated based on the Bragg diffraction law. Additionally, the structural colors of metal-NPs/PS hybrid CPhC color films were assessed through color measurements based on the Commission International d’Eclairage 1931 standard colorimetric system. Finally, this chapter exhibits a simple method to generate tunable structural color of functional materials for numerous applications, such as in textile fabrics, bionic colors, catalysis, and paint.
Optical Excitations of Colloidal Core/Shell Semiconductor Quantum Dots
Authors: O. Cheche Tiberius
Published: November 2016

The energy structure of multi‐layer core/shell semiconductor quantum dots (QDs) is simulated and the optical absorption is described within the linear response theory. The lattice‐mismatch strain field of the multi‐layer nanostructures of spherical symmetry is modelled by a linear continuum elasticity treatment. The excitonic effect is estimated by a configuration interaction approach. Multi‐layer core/shell QDs of II‐VI semiconductors with heterostructures of type I and II are discussed. Localization of the photo-excited carriers induced by coating explains the optical stability of these multi‐layer nanostructures.
Manganese Sulfide (MnS) Nanocrystals: Synthesis, Properties, and Applications
Authors: M. Ferretti Anna , Mondini Sara , Ponti Alessandro
Published: November 2016

Manganese(II) sulfide (MnS) is an interesting material for both fundamental and applicative research, especially when its bulk properties are modulated by reducing the size into the nanometric region (< 100 nm). Due to its polymorphism, MnS is an attractive material to develop synthetic strategies for polymorphism control. We have reviewed the literature concerning MnS nanosystems having at least one dimension smaller than 100 nm. Successful synthetic techniques for the preparation of zero- and one-dimensional MnS nanosystems (either homogeneous and heterogeneous) with size, shape, and polymorphism control are presented with emphasis on solvothermal techniques and on studies devoted to understanding the growth mechanism and the polymorphism. Properties and applications are collected in three broad areas corresponding to nanosize MnS used as an optical, electric, and magnetic material. MnS has attracting properties such as its large bandgap, which makes it promising for emission in the ultraviolet region. The magnetic properties have also arisen attention since MnS is antiferromagnetic at low temperature and (super)paramagnetic at room temperature. Finally, the layered structure of the hexagonal polymorph is responsible for the good performance of nanosize MnS as a lithium-ion battery electrode or supercapacitor material since the insertion/exchange of small ions is easy.

Published: November 2016

The recent progress in functionalized LB films and supramolecular gels varies and occupies various fields. Self-assembly technique is playing an important role in preparing well-defined multilevel nanostructures and the functionalized nanomaterials with the designed and controlled properties. In this chapter, various kinds of functionalized LB films and supramolecular gels, including gold nanoparticles, inorganic-organic hybrid composites, and graphene oxide nanocomposites, have been demonstrated and analyzed. We show main research contributions in recent years in two sections: preparation and self-assembly of some functionalized LB films and preparation and self-assembly of some functionalized supramolecular gels. The above research work may give the potential perspective for the design and preparation of new self-assembly nanomaterials. Future research on preparation of LB films and supramolecular gels will depend on the novel applications and special nanostructures in order to produce novel functional nanomaterials and devices.
Adsorption of Ions at the Interface of Clay Minerals and Aqueous Solutions
Authors: Jia Zengqiang , Wang Qian , Zhu Chang , Yang Gang
Published: November 2016

Adsorption of ions at the interface of clay minerals and aqueous solutions plays a critical role in a wide spectrum of colloidal, chemical, physical, and geological processes. Owing to the particular complexity of related systems and the femtosecond scale of related processes, the direct experimental observations often become a challenging task. As a contrast, computer simulations have proven to be a competent and powerful approach therein and already realized fruitful and significant contributions. In this chapter, we attempt to draw a relatively comprehensive picture of the interfacial adsorption of ions mainly within the context of computer simulations. As elaborated, quantum mechanics (QM) and molecular dynamics (MD), two popular simulation techniques currently used, have respective advantages, and with their collaborative efforts, we are striding toward the in-depth and systematic understanding of adsorption configuration, distribution, stability, reaction thermodynamics and mechanism, dynamics, diffusivity as well as electric double layer and other fundamental issues that are closely associated with the adsorption of ions at the interface of clay minerals and aqueous solutions. In addition, we demonstrate that investigation of the interfacial adsorption of ions greatly helps to unravel the origin and mechanism of ion-specific effects, whose importance has been explicitly suggested to be no less than Gregor Mendel’s work to genetics.

Jean Itard e Victor do Aveyron: olhares contemporâneos sobre a narrativa de uma experiência pedagógica do início do século XIX
Authors: Pieczkowski Tania Mara Zancanaro
Published: November 2016

Este artigo surgiu do desafio do Grupo de Estudos e Pesquisaem Educação Especiale Inclusão – GEPE da Universidade Federal de Santa Maria (UFSM), para escrever sobre o encontro do médico Jean Itard e o garoto selvagem conhecido como Victor do Aveyron. A elaboração deste texto toma como materialidades empíricas as meticulosas narrativas escritas por Itard na França, no período de1801 a1806. O estudo objetiva analisar esse acontecimento histórico a partir das leituras do presente e compreender a influência de epistemologias e políticas educacionais nas práticas da Educação Especial. O estudo evidencia as mudanças entre uma educação individual, pautada da educação dos sentidos e políticas atuais de inclusão, instigando, também, a refletir se a lógica da “educação para todos” não apresenta o risco da negação da diferença. A análise dos relatórios do trabalho educacional de Itard e Victor do Aveyron contribui para a compreensão de uma época, mas provoca, também, a reflexão acerca de indagações ainda presentes quanto à interferência de aspectos biológicos e sociais no desenvolvimento humano. Apesar dos entusiasmos e desencantos explicitados por Itard na educação de Victor, sua experiência analisada com referenciais epistemológicos contemporâneos contribui para a compreensão da necessária ruptura com crenças no determinismo biológico, enfatizando a importância da interação social para a aprendizagem e desenvolvimento humano.
A educação do garoto selvagem de Aveyron e a proposta contemporânea de escolarização de alunos com transtorno do espectro autista: possibilidades de leitura
Authors: Guareschi Taís , Naujorks Maria Inês
Published: November 2016

Neste artigo, temos como objetivo analisar a experiência pedagógica de Jean Itard com o menino selvagem, refletindo sobre a presença do ideário desse médico-pedagogo na proposta contemporânea de escolarização de alunos com transtorno do espectro autista. Itard, ao contrário de outros médicos, apostou na educabilidade de Victor, supondo que suas dificuldades eram decorrentes do longo abandono vivenciado. A proposta de Itard era de caráter eminentemente educativo, tendo como premissas orientadoras que o conhecimento e as ideias advêm das sensações e que cada sentido deveria ser estimulado isoladamente. Com base na análise empreendida sobre essa experiência pedagógica, refletimos sobre a presença desse ideário na educação de alunos com autismo. Para tanto, propomos a discussão a partir de um ponto central: a primazia do método de ensino na proposta pedagógica de Itard. Na contemporaneidade, a inclusão escolar de alunos com transtorno do espectro autista impele os professores a demandar um método de ensino, que garanta como resultado a aprendizagem dos conhecimentos escolares. Atentamos para a possibilidade dessa demanda repetir o cerne da proposta de Itard, que era o método. Tendo este como foco central, as manifestações singulares poderão ser apagadas ou tomadas como um entrave a ser superado na educação desses sujeitos.

Large-scale remodeling of a repressed exon ribonucleoprotein to an exon definition complex active for splicing
Authors: Wongpalee Somsakul Pop , Vashisht Ajay , Sharma Shalini , Chui Darryl , Wohlschlegel James A , Black Douglas L
Published: November 2016

Polypyrimidine-tract binding protein PTBP1 can repress splicing during the exon definition phase of spliceosome assembly, but the assembly steps leading to an exon definition complex (EDC) and how PTBP1 might modulate them are not clear. We found that PTBP1 binding in the flanking introns allowed normal U2AF and U1 snRNP binding to the target exon splice sites but blocked U2 snRNP assembly in HeLa nuclear extract. Characterizing a purified PTBP1-repressed complex, as well as an active early complex and the final EDC by SILAC-MS, we identified extensive PTBP1-modulated changes in exon RNP composition. The active early complex formed in the absence of PTBP1 proceeded to assemble an EDC with the eviction of hnRNP proteins, the late recruitment of SR proteins, and binding of the U2 snRNP. These results demonstrate that during early stages of splicing, exon RNP complexes are highly dynamic with many proteins failing to bind during PTBP1 arrest.
Spectroscopic investigation of autoionizing Rydberg states of palladium accessible after odd-mass-selective laser excitation
Authors: Kobayashi Tohru , Locke Clayton R. , Midorikawa Katsumi
Published: November 2016

Excitation of palladium to autoionizing Rydberg states are investigated in order to realize efficient ionization after odd-mass-selective excitation. Wavelength resolution is sufficient to distinguish two autoionizing Rydberg series: 4d9(2D3/2)np

and 4d9(2D3/2)np

converging to Pd II 4d9(2D3/2) as is expected from transition selection rules. Of all observed transitions, the largest autoionization yield is found to be through the 4d9(2D3/2)11p

state at 69055.2 cm−1. From fitting analysis of the observed members of the 4d9(2D3/2)np

series, we have obtained the energy of Pd II 4d9(2D3/2) to be 70780.38 ± 0.08 cm−1.

Authors: Hoque Kazi Enamul , Kamaluddin Megat Ahmad , Abdul Razak Ahmad Zabidi , Abdul Wahid Afiq Athari
Published: November 2016

Background

Overweight and obesity have increased rapidly in incidence to become a global issue today. Overweight and obesity problems are significantly linked to unhealthy dietary patterns, physical inactivity and misperception of body image. This study aimed to determine whether Malaysian children build healthy eating habits from childhood.

Methods

A survey on eating habits was conducted among primary school students in standards 4 to 6 in the state of Selangor, Malaysia. The findings of the study were reported in the form of descriptive statistics involving frequencies and percentages. Data from 400 respondents were analyzed.

Results

Our findings showed that the students understood the definition of healthy food and the types of food that are considered healthy. Although the students knew that food such as deep-fried drumsticks and hamburgers contain a high amount of saturated fat and cholesterol, these foods were still consumed by them. There was also a high consumption of foods that are fried and contain sugar, salt and saturated fat. In choosing food, two major factors contributed to the students’ decisions: cleanliness (65.8%) and the preference of their parents (12.3%).

Discussion

Our findings indicate that by implementing the Integrated School Health Program (ISHP) properly, students’ eating habits can be improved by creating a school with a healthy environment.
Legionellashows a diverse secondary metabolism dependent on a broad spectrum Sfp-type phosphopantetheinyl transferase
Authors: Tobias Nicholas J. , Ahrendt Tilman , Schell Ursula , Miltenberger Melissa , Hilbi Hubert , Bode Helge B.
Published: November 2016

Several members of the genusLegionellacause Legionnaires’ disease, a potentially debilitating form of pneumonia. Studies frequently focus on the abundant number of virulence factors present in this genus. However, what is often overlooked is the role of secondary metabolites fromLegionella. Following whole genome sequencing, we assembled and annotated theLegionella parisiensisDSM 19216 genome. Together with 14 other members of theLegionella, we performed comparative genomics and analysed the secondary metabolite potential of each strain. We found thatLegionellacontains a huge variety of biosynthetic gene clusters (BGCs) that are potentially making a significant number of novel natural products with undefined function. Surprisingly, only a single Sfp-like phosphopantetheinyl transferase is found in allLegionellastrains analyzed that might be responsible for the activation of all carrier proteins in primary (fatty acid biosynthesis) and secondary metabolism (polyketide and non-ribosomal peptide synthesis). Using conserved active site motifs, we predict some novel compounds that are probably involved in cell-cell communication, differing to known communication systems. We identify several gene clusters, which may represent novel signaling mechanisms and demonstrate the natural product potential ofLegionella.
Relación Entre Mentalización y Sensibilidad de Madres de Infantes de Un Año de Edad y su Efecto en su Desarrollo Socioemocional

Published: November 2016

El objetivo de este estudio fue analizar la relación entre la mentalización y sensibilidad materna en la interacción de madres de la Región Metropolitana de Chile con sus hijos de un año de edad y su implicancia en el desarrollo socioemocional (DSE) infantil en una muestra no probabilística intencionada de 105 madres de distinto nivel socioeconómico (NSE) y sus hijos/as que asistían a salas cuna públicas o privadas. Los instrumentos utilizados fueron la Escala de Sensibilidad del Adulto (E.S.A.), Evaluación de la Mentalización del Adulto Significativo y la escala de desarrollo socioemocional de la Escala de Desarrollo Infantil de Bayley-III. Mediante análisis correlacionales y comparativos de medias y frecuencias (t de Student y 2), se observó una correlación entre mentalización y sensibilidad materna y entre esta y el DSE del niño; no así con la mentalización. El NSE tiene implicancia en la calidad de la sensibilidad materna, mentalización y el nivel del DSE y, al ser controlado, desaparece la relación entre sensibilidad materna y DSE infantil. Se discuten las implicancias de incorporar intervenciones tempranas en estas competencias maternas.
O APOGEU E A CRISE DA PROGRAMAÇÃO INFANTIL NA TELEVISÃO BRASILEIRA: AS ADAPTAÇÕES DO SÍTIO DO PICAPAU AMARELO
Authors: Balbino Jéfferson , Da Silva Marcela Verônica
Published: November 2016

A programação televisiva infantil brasileira surge como um elemento lúdico graças à influência do teatro. Porém, aos poucos, passa a adquirir identidade própria que não deixa de ter a interferência da indústria cultural, ou cultura de massa. Assim, no presente artigo busca-se traçar o perfil dessa programação ao longo do tempo, desde o seu surgimento no Brasil até os dias atuais. Para tanto, toma-se como exemplo as diversas adaptações d’O Sítio do Picapau Amarelo de Monteiro Lobato para a televisão, em especial a última versão produzida pela TV Globo em 2001. Como referencial teórico, serão utilizadas algumas considerações sobre o lúdico, presentes nos trabalhos de Johan Huizinga e Walter Benjamin e reflexões de Theodor Adorno, Max Horkheimer e Edgar Morin a respeito da indústria cultural.
MADE IN BRAZIL: ENTRE OS LAÇOS DAS MIGRAÇÕES NA IDENTIDADE DA MÚSICA BRASILEIRA DOS ANOS 1970
Authors: Ávila Jackson Gil , Sá Jussara Bittencourt de
Published: November 2016

O presente artigo procuramos refletir sobre as migrações na identidade musical brasileira dos anos 1970. Nossa pesquisa focaliza artistas que fizeram parte do movimento Made in Brazil e das associações que foram estabelecidas com o mercado fonográfico e com a televisão, mais especificamente as novelas e suas trilhas sonoras. Como recorte para estudar o movimento Made in Brazil, elegemos os cantores Fábio Júnior (Mark Davis e Uncle Jack), Chrystian e Michael Sullivan, além do grupo musical Pholhas. O objetivo é analisar como se construiu a identidade musical estrangeira de cada artista e quais os desdobramentos que se estabeleceram na carreira de cada um, após o fim do movimento. Esta pesquisa configura-se como um estudo de caso, e a análise desenvolvida tem como base os pressupostos da micro e da macro análise. As reflexões teóricas aportam-se em estudos sobre nação, identidades, migrações e indústria cultural, além de autores que possibilitaram a caracterização histórico-social da época destacada, enfatizando a música brasileira e o movimento analisado. Destacamos que o movimento Made in Brazilfoi, em seu tempo, exitoso, na medida em que soube utilizar da indústria cultural para estabelecer um contato estreito com o público e, assim, promover os artistas e suas músicas, bem como as trilhas sonoras das telenovelas; colocando em cena os “estrangeiros brasileiros”.

Este texto tem como tema a análise da segunda versão do documento nacional intitulado Base Nacional Comum Curricular na área da Arte Visual. É síntese de uma fala apresentada no IV Encontro Sul do Arte na Escola realizado na FURB, Blumenau, SC. Apresenta-se a seguinte estrutura: a formação dos professores e o perfil desses profissionais; as vivências em ensino da Arte nos últimos anos e os processos legais implicados; os processos de escolha, seleção e organização curricular; o que a BNCC sinaliza acerca das artes visuais; e, por fim, reflete-se como as práticas atuais sinalizam processos de resistência na realidade escolar. Compreende-se que os documentos curriculares são parte do processo curricular, mas que, na prática, os professores apoiam suas escolhas em outros aspectos relacionados ao cotidiano escolar, ao contexto e ao que conhecem e compreendem por arte. Ainda, a BNCC compreende a Arte como linguagem e o documento acena algumas fragilidades em relação à formação polivalente no que tange aos anos iniciais. Em relação aos objetivos, o documento articula temas integradores que limitam, na maneira como são apresentados, a compreensão da arte. Os elementos metodológicos não são claros, fragilizando, assim, a compreensão dos professores em relação à epistemologia que permeia o documento na área das Artes Visuais.

Importance

It is not well understood if and how various social and environmental determinants of health (SEDoH) are associated with mortality rates related to cardio-kidney-metabolic syndrome (CKM) across the US.

Objective

To study the magnitude of the association strength of SEDoH with CKM-related mortality at the county level across the US.

Design, Setting, and Participants

This cross-sectional, retrospective, population-based study used aggregate county-level data from the US Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (WONDER) data portal from 2010-2019. Data analysis occurred from September 2023 to January 2024.

Exposures

A total of 7 diverse SEDoH were chosen, including median annual household income, percentage of racial and ethnic minority residents per county, fine particulate air pollution (PM2.5) concentrations, high-school completion rate, primary health care access, food insecurity, and rurality rate.

Main Outcomes and Measures

The primary outcome was county-level age-adjusted mortality rate (aaMR) attributable to CKM. The association of county-level CKM-related aaMR with the 7 SEDoH was analyzed using geographically weighted models and the model median coefficients for each covariate studied.

Results

Data from 3101 of 3243 counties (95.6%) were analyzed. There was substantial variation in SEDoH between states and counties. The overall pooled median (IQR) aaMR (2010-2019) in the US was 505.5 (441.3-578.9) per 100 000 residents. Most counties in the lower half of the US had rates much higher than the pooled median (eg, Southern US median [IQR] aaMR, 537.3 [466.0-615.9] per 100 000 residents). CKM-related mortality was positively associated with the food insecurity rate (median [IQR] β = 6.78 [2.78-11.56]) and PM2.5 concentrations (median [IQR] β = 5.52 [−11.06 to 19.70]), while it was negatively associated with median annual household income (median [IQR] β = −0.002 [−0.003 to −0.001]), rurality (median [IQR] β = −0.32 [−0.67 to 0.02]), high school completion rate (median [IQR] β = −1.89 [−4.54 to 0.10]), racial and ethnic minority rate (median [IQR] β = −0.66 [−1.85 to 0.89]), and primary health care access rate (median [IQR] β = −0.18 [−0.35 to 0.07]).

Conclusions and Relevance

In this cross-sectional study of county-level data across the US, there were substantial geographical differences in the magnitude of the association of SEDoH with CKM-related aaMR. These findings may provide guidance for deciding local health care policy.

Phenazine‐based small molecular acceptors (SMAs), which benefit from the reduced energy loss (Eloss), have emerged as promising candidates for achieving high‐efficiency organic solar cells (OSCs). Nevertheless, the potential advancements of phenazine‐based photovoltaic devices are hindered by the constrained short‐circuit current (Jsc). Though the incorporation of selenium (Se) atoms has been proven effective in enhancing Jsc, it simultaneously introduces molecular disorder stacking and charge recombination. Based on the desire to harness the full potential of phenazine structure and the benefits of Se substitution, a series of Se‐substituted phenazine‐based SMAs, namely PzIC‐SSe‐4F and PzIC‐SeSe‐4F are meticulously synthesized. Due to the increased photon harvesting capabilities, the photovoltaic device using PzIC‐SeSe‐4F demonstrated a significantly increased Jsc of 27.73 mA cm−2. Remarkably, the PzIC‐SeSe‐4F‐based device displayed an astonishing open circuit voltage (Voc) of 0.873 V, representing the highest Voc recorded among all reported symmetric Se‐substituted Y‐series SMAs‐based photovoltaic devices. Thanks to the synergistic effect of phenazine central cores and Se substitution, the PM6:PzIC‐SeSe‐4F‐based device achieves a power conversion efficiency (PCE) of 17.69%. The findings serve as a pivotal reference for further development of high‐efficiency Se‐substituted photovoltaic devices.

Noticeable progress has been made in mechanically strong and tough of polymer gels, whereas this consistency between mechanical robustness and perfect elasticity remains a challenge. Here, a simple method is conducted for fabricating hyperelastic hydrogels based on the proposed molecular engineering of dissipative energy taking advantage of two distinct interactions with great difference of binding energy. This molecular engineering of dissipative energy refers to the complementarity at the molecular level between strong and weak interactions: the strong interaction provides the mechanical strength, the weak interaction eliminates the yielding and dense chain entanglements are further implanted, resulting in the perfect hyperelasticity. Such a complementarity in reformation time and binding energy of two interactions triggers a wide range of controllable window for regulating mechanical performances, filling the current gap in the design of hyperelasticity using only high‐order structures. The resultant hyperelastic hydrogels exhibit remarkable tensile strength and linear elastic deformation, but also outstanding swelling resistance, biocompatibility, hydrophilicity, and skin‐like elastic moduli. The work thus provides a promising concept for designing elastic and robust polymer gels and brings a new perspective in the combination of mutually incompatible mechanical properties, which will likely promote innovative applications in bioengineering and bioelectronics.

Microplastics (MPs), formed from the physical breakdown of larger plastics, have been found across a variety of ecosystems. Much research has been done on the effects of MPs in aquatic ecosystems, but fewer studies have explored their effects in terrestrial environments, particularly in agroecosystems where modern practices contribute strongly to MP soil pollution (e.g., plasticulture, fertilization with contaminated biosolids, and composts). Aquatic pharmaceutical contamination is also considered an emerging pollutant threat. Naproxen, a commonly used drug, has been found in wastewater and natural freshwater bodies globally. Thus, crops may be exposed to multiple pollutants simultaneously through soil and water inputs. Our research provides insight into the individual and interactive effects of soil MP pollution intensity and exposure to naproxen‐contaminated water on growth and development of Lactuca sativa (lettuce). Soil abiotic factors (pH, electrical conductivity, and rates of soil moisture loss) are also reported. We found that 7% polyester MP‐contaminated soil significantly reduced total aboveground biomass and coarse root biomass, while both 0.03% and 7% polyester MP‐contaminated soil significantly reduced leaf count and average leaf size. However, 1 mg/L naproxen had no effect on plant growth or development, and there were no interactive effects of naproxen with MPs. MPs also significantly increased rates of soil moisture loss, but we found no effects of MPs or naproxen on soil pH or electrical conductivity. Predicted global increases in soil MP contamination levels will potentially have negative consequences for food systems.
Assessing the use of native rhizobia to improve nitrogen fixation under abiotic stress

Biological nitrogen fixation by rhizobia bacteria plays a pivotal role in sustainable agriculture by converting atmospheric nitrogen into a form that plants can assimilate, thereby reducing the need for synthetic fertilizers. This process can be dramatically reduced by various abiotic stressors. Native rhizobia strains, which are naturally occurring, may be better adapted to the local soil and climatic conditions, making them more resilient to stress factors such as drought, salinity, temperature extremes, and pH variations compared to commercial strains that may have been developed in and for different environments. This study aimed to compare the efficacy of native rhizobia species with a commercial inoculant and uninoculated controls in maintaining nitrogen fixation under induced stress by delayed planting in field peas over two growing seasons (2021 and 2022) in central South Dakota. Our findings indicate that native rhizobia, while not outperforming the commercial inoculant, demonstrated competitive nitrogen fixation capacities. Overall, total nitrogen fixation was not statistically different between a commercial inoculant and native rhizobia formulations. Planting date emerged as a significant factor influencing nitrogen fixation, with later planting substantially reducing overall effectiveness. These results highlight the potential of native rhizobia as an alternative to commercial inoculants and underscore the need for increased screening throughput and improved methods to assess rhizobia efficacy and nodule competition in field settings.
An elevational cline in leaf variegation: Testing anti‐herbivory and abiotic heterogeneity hypotheses in maintaining a polymorphism
Authors: Sullivan Cierra N. , Koski Matthew H.
Published: September 2024

Premise

While some studies have found leaf variegation to reduce photosynthetic capacity, others showed that it can increase photosynthesis. Thus, what maintains variegation remains an open question. Two primary hypotheses—the anti‐herbivory and abiotic heterogeneity hypotheses—have been posited, yet little empirical research explicitly investigates the maintenance of naturally occurring variegation.

Methods

We used field surveys, image analysis, and climatic associations to explore the anti‐herbivory and abiotic heterogeneity hypotheses in 21 populations of Hexastylis heterophylla and H. shuttleworthii, both polymorphic for leaf variegation. We measured the frequency of variegated individuals, variegation intensity, and herbivory for each morph, assessed abiotic correlates with variegation, and measured photosynthetic efficiency.

Results

We found a strong elevational cline in leaf variegation strongly linked with abiotic heterogeneity; variegation was more common in lower‐elevation populations characterized by higher temperatures, UV‐B exposure, seasonal light change, and drier, more basic soils. Variegated and nonvariegated individuals experienced similar levels of herbivory. Morphs had similar photosynthetic quantum yields. However, nonvariegated leaves experienced more nonphotochemical quenching, an indication of photoinhibition, and had higher surface temperatures under high light.

Conclusions

Our results suggest that variegation may serve as an adaptation to high temperatures and light conditions and can reduce photoinhibition in certain environmental contexts. Thus, abiotic factors can maintain variegation in wild populations and shape geographic clines in variegation.
Social ecological predictors and correlates of Latinos' IPV behaviors: A systematic review and critique of the research literature
Authors: Manriquez Adrian Luis , Mankowski Eric S.
Published: September 2024

The current paper utilizes an ecological level of analysis framework to review and critique the literature surrounding predictors, correlates, and antecedents of Latinos' intimate partner violence (IPV) behaviors. More specifically, the ecological levels of analysis framework was employed to demonstrate how Latino males' IPV perpetration is being understood and studied. A total of n = 34 peer‐reviewed articles were reviewed and critiqued. Findings indicated that most IPV research is being conducted at and comprehended from the individual (n = 33; 97%) and microsystem/small group (n = 24; 71%) levels of analysis, while linkages to organizational, locality, and institutional levels of analysis are largely neglected. Researchers and interventionists appear to view Latinos' IPV behaviors through deficit models, employ decontextualized and homogenized representations of the population, and neglect higher ecological levels of analysis. These three shortcomings in IPV research as it pertains to Latino populations must be addressed in future research studies if investigators desire to end the stigmatization and demonization of Latinos as a cultural and people group, and to maximize battering intervention effectiveness and efficiency for men of Latino origin.

Published: September 2024

Ortho‐Phthaldehyde (OPA) is one of the isomers of benzenedicarbaldehydes. It exhibits distinctive chemical properties stemming from the closely attached dicarbaldehyde groups. Since its development, it has been widely employed as a potent disinfectant, owing to its inherent antimicrobial properties. OPA has the ability to form a fluorescent product with primary amines, making it useful for detecting and estimating various biogenic amines, peptides, and proteins in bodily fluids. Moreover, the combination of thiol and amine with OPA produces a more sensitive fluorogenic compound, significantly enhancing the sensitivity and specificity of OPA‐based analytical techniques. This review summarizes recent developments in biochemical analysis using OPA. It also discusses key achievements in the development of photoactive polymers. Additionally, it covers the use of OPA as a synthetic precursor to achieve small molecules with unique structures that have become increasingly important in various fields of scientific research from 2004.
