Published: September 2022

La agriculturización es un causante de transformación en los territorios. El actual modelo de agricultura predominante, basado en la aplicación de plagui- cidas para mantener el cultivo saludable y sin competencia, no solo afecta a la especie objetivo sino también a aquellas no blanco, impactando en la biodiversidad local y el funcionamiento de los ecosistemas. El objetivo del presente estudio fue analizar los cambios en los usos del suelo en la Cuenca Alta del Arroyo Chapaleofú y determinar la toxicidad del clorpirifos sobre una especie no blanco. Para esto, se compararon imágenes clasificadas supervisadas de los años 1989 y 2019 del partido de Tandil (Buenos Aires, Argentina) y se realizó la evaluación de la Concentración Letal 50 (CL50) del insecticida clorpirifos sobre el molusco Physa acuta, a 96 horas de exposición. Se detecta un 74.35% de avance de las tierras destinadas a actividades agrícolas, lo que evidencia el proceso de agriculturización. El molusco Physa acuta tiene una CL50 de 0.55 mg L−1, presentando al mismo tiempo efectos subletales, pese a tratarse de una especie tolerante al químico en cuestión. Debido a lo anterior, es necesario realizar más estudios que permitan determinar los efectos de los múltiples químicos utilizados en la actividad agrícola, considerando exposiciones más prolongadas y con especies más sensibles.

Anaerobic Digestion (AD) has proven to be an economically viable technology to treat the organic fraction of the municipal solid wastes (OFMSW). Research regarding the management and application of AD byproducts in Mexico, is required to encourage the private sector and local administrations to invest in this technology. In this study, fodder winter triticale (x triticosecale Wittm. ex A. Camus var. Rio Nazas) was grown to demonstrate the fertilizer effect and to evaluate the raw digestate generated from the AD under thermophilic conditions of locally sampled OFMSW, using a batch scale digester. The digestate produced was incorporated into a 6 m2 plot according to the recommender fertilization for this crop. At the same time, a crop treated with inorganic fertilizer (IF) and a control were grown, each on a plot of same dimensions, for comparison purposes. The fertilizer effect was measured in crop yield (Mg ha−1), seed efficiency (kgTriticale kgSeed−1) and bromatological value. Overall, the digestate treatment had better results in crop yield (12.54 Mg ha−1) and seed efficiency (83.61 kgTriticale kgSeed−1) than those achieved with the IF (11.16 Mg ha−1 and 74.43 kgTriticale kgSeed−1 , respectively) and the control. Whereas the bromatological value, a statistical analysis revealed that, regardless of the treatment, the mineral uptake, protein, sugar and fiber content were not significantly different (p > 0.05). Raw digestate generated from AD of the OFMSW under thermophilic conditions, is a valuable by product, rich enough to fully substitute IF for growing triticale Río Nazas.

Published: September 2022

La agricultura convencional con el establecimiento de monocul- tivos y el uso indiscriminado de plaguicidas impacta de forma negativa la fertilidad del suelo. El cultivo de especies leguminosas es una alternativa para mejorar las condiciones del suelo y producir alimento. Por ello, se determinaron las propiedades físicas y químicas del suelo, antes y después del cultivo de Phaseolus vulgaris, Vigna unguiculata y Vigna radiata. Antes de iniciar el cultivo el productor evaluó la calidad del suelo mediante indi- cadores visuales cualitativos. Se establecieron tres tratamientos bajo un diseño de bloques completos al azar y por medio del análisis de varianza se compararon las propiedades fisicoquímicas, antes y después del cultivo. La calidad del suelo es moderada tanto por la evaluación visual como por el análisis químico. Se observaron efectos del tratamiento en la CIC y Ca, los cuales disminuyeron después de los cultivos. El policultivo de leguminosas contribuye a mejorar las condiciones del suelo.

Los combustibles forestales son uno de los principales reservorios de carbono, pero también se consideran un factor involucrado en la ocurrencia e intensidad de incendios forestales. El objetivo de este estudio fue analizar la dinámica temporal de almacenamiento y efecto del incendio sobre los combustibles forestales en bosque de pino (Pinus oocarpaSchiede). La medición hojarasca, mantillo y materiales leñosos se realizó de 2010 a 2021 en cuatro sitios de un bosque de pino del Cerro Nambiyugua, Villaflores, Chiapascon el método del Inventario Nacional Forestal y de Suelos. En cada sitio, se utilizaron ocho cuadrantes de 30 x 30 cm2 para colectar las muestras de hojarasca y mantillo.  Para el secado de las muestras, se utilizaron bolsas de papel estraza y se colocaron en estufa a 70°C durante 72 horas. El material leñoso caído se determinó con la metodología de interseccion planar. La carga de hojarasca y mantillo aumentó gradualmente con el tiempo Las mayores cargas de hojarasca se obtuvieron en el año 2018 con 12.67 t ha-1. Después del incendio forestal del año 2019, la carga de hojarasca disminuyo a 5.67 t ha-1, y para el 2021 aumento a 8.65 t ha-1. La tendencia de acumulación de material leñoso caído varió según la categoría de horas de ignición. Los resultados de este estudio tienen implicaciones fundamentales en las estrategias y periodicidad del manejo de carga de combustibles forestales y almacenamiento de carbono ya que con el cambio climático se espera mayor frecuencia de incendios forestales.

El kéfir es un producto de leche fermentada que contiene una microbiota simbiótica que genera beneficios para la salud al sintetizar diferentes metabolitos y enzimas con diversas capacidades metabólicas. Por otra parte, los plásticos sintéticos utilizados en sectores del hogar e industrial, han originado un problema ambiental alrededor del mundo debido a su uso desmedido, su alta durabilidad y la falta de reciclado. Por tal motivo, el estudio de los consorcios de kéfir representa una fuente para la obtención de microorganismos productores de enzimas hidrolíticas capaces de degradar plásticos. En este estudio, se analizaron dos metagenomas de kéfir (NCBI proyecto PRJNA704713), mediante herramientas bioinformáticas, dirigidos a la búsqueda de secuencias homólogas a hidrolasas, así como el aislamiento de microorganismos relacionados con la degradación de plásticos tipo PET. Los resultados obtenidos permitieron la identificación de dos secuencias de kéfir homólogas a las enzimas dienolactona hidrolasa (DLH-1 y DLH-2) que han sido relacionadas con la degradación de compuestos plásticos. Ambas secuencias presentan un dominio compartido con la superfamilia alfa/beta hidrolasas; este tipo de motivo se ha observado en las PET hidrolasas obtenidas en diferentes especies de actinomicetos. Así mismo, se aislaron seis bacterias que mostraron diferentes características y capacidades para degradar plásticos PLC. En conclusión, los metagenomas del kéfir presentan secuencias de enzimas asociadas a la degradación de plásticos tipo PET y los microorganismos aislados del kéfir fueron capaces de degradar PLC, lo que sugiere que representan un potencial para la degradación de plásticos PET.

Acceder a la realidad para ser estudiada desde cualquier perspectiva requiere desarrollar en el sujeto un proceso cognitivo que apuran rutas complejas que le permita explicar ésta; el ordenamiento, la sistematización, así como la interpretación de la información son temas que puede ser clave en las intenciones de la investigación. Una manera de organizar el saber en un sistema de ideas, desde la perspectiva de la transdisciplinariedad compleja, significa trazar una metodología que permita al pensamiento y al lenguaje establecer un camino hacia el análisis. Una propuesta así apunta a una dimensión hermenéutica, es decir a la comprensión de lo que edifica el investigador al recuperar información de la realidad y de las teorías desde donde se explica esa realidad.
Este trabajo tiene como intención académica proponer y definir el uso de la Matriz Categorial, no solo como mecanismo creativo de la investigación, sino también como un recurso técnico que posibilita el proceso cognitivo para lograr interpretación y comprensión de lo estudiado. La matriz categorial es concebida aquí como una fuente de saber desde donde germina el conocimiento a partir de las conexiones más profundas entre categorías evitando la vaguedad o la simple descripción de éstas.

Antithrombotic therapy in patients undergoing transcatheter aortic valve replacement (TAVR): from current evidence to perspective
Authors: Mauri Silvia , Lanzillo Giuseppe , Ferlini Marco
Published: September 2022

The use of transcatheter aortic valve replacement (TAVR) for care of symptomatic severe aortic stenosis has increased over the last years; after initially treating patients at prohibitive or high surgical risk, nowadays the procedure can be considered for intermediate or low surgical risk. Although thrombotic events (ischemic stroke, myocardial infarction, and leaflet thrombosis) decreased in patients at lower risk, antithrombotic therapy after TAVR is still recommended. However, the optimal antithrombotic regimen is a still matter of debate due to the lack of randomized data and the concomitant increased risk of bleeding events. In the present review, we analyze current data, recommendations of international guidelines and consensus documents, and potential future scenarios with a rational approach of separation of patients with or without a pre-procedural indication for long-term oral anticoagulant therapy.
Molecular characterisation of the current cultivars of Vitis vinifera L. in Lanzarote (Canary Islands, Spain) reveals nine individuals which correspond to eight new varieties and two new sports

Published: September 2022

Vine was reintroduced to the volcanic island of Lanzarote (Spain) more than 300 years ago. The phylloxera plague has never reached the island; consequently, Vitis vinifera L. has evolved continuously since then due to the influence of some abiotic factors, such as low rainfall and strong winds. The aim of this study was to determine the inter- and intra-varietal diversity of the island’s vines and the potential evolution of singularity. Two hundred and twenty-three samples were genotyped with 20 SSR (Simple Sequence Repeats).
The following results were obtained from these analyses: 8 new varieties (Blanca de la granja del cabildo (W), Burra chinija (W), Diego chinija (W), Lemes del Cabezo (W), Malvasia alistanada fina (W), Malvasia alistanada rustica (W) (a mutation of Malvasia alistanada fina), Sinforiano chano (Rs), Uvillón negro (R), Vijariego blanco de la granja (W)), and 2 new sports (Chasselas lajiares (Rs) and Diego de El Raso rosado (Rs)).
In addition, scientific studies on varieties from the island of Lanzarote describe four local cultivars: Breval negro (Rg), Malvasia volcanica (W), Torrontes volcanico (W) and Uva de año (R), which means that a total of 12 local varieties and 2 colour mutations have been described for this Atlantic island. It should also be noted that the appearance of 100 new molecular profiles with their corresponding names represents an unprecedented lexical enrichment. Lanzarote can be considered a centre of biodiversity, as is the Canary archipelago as a whole. Their vines have evolved to such an extent that they are now genetically different from the original populations. The vines from Lanzarote could be of great interest to the wine sector, as they can act as a nursery from which better-adapted vines can be obtained to mitigate the effects of climate change.
O ESTATUTO DA FÍSICA NA METACIÊNCIA DE DESCARTES: ENTRE O IDEALISMO E O REALISMO PRAGMÁTICO
Authors: De Azevedo Júnior Ivânio Lopes
Published: September 2022

Neste artigo, colocamos a questão sobre o estatuto da Física no pensamento de René Descartes em meio a duas leituras divergentes. De um lado, apresentamos e criticamos a interpretação idealista de Martial Gueroult em torno do problema e, noutra perspectiva, apresentamos e defendemos a interpretação realista-pragmática, de Zeljko Loparic e Érico Andrade, como sendo a mais adequada para se compreender a natureza da física no pensamento cartesiano. O objetivo central é saber como Descartes concebe a sua própria ciência hipotética frente às exigências metodológicas que ele mesmo extrai da matemática. Após entendermos em que medida a relação entre metafísica, matemática e física não ocorre de modo pacífico no interior do sistema cartesiano, passamos ao tratamento específico das duas interpretações, destacando seus respectivos compromissos filosóficos e suas diferentes escolhas textuais. Apesar da vasta literatura especializada sobre a obra de Descartes, no Brasil, o debate em torno da ciência cartesiana ainda é incipiente quando comparamos com a quantidade de artigos e livros que priorizam os temas clássicos da sua metafísica. Com o intuito de diminuir tal lacuna, retomamos este tema específico do pensamento de Descartes, explicitando as mediações e problematizações que lhe são inerentes.
A Complete Proof Of The Riemann Hypothesis Based On A New Expression Of $\xi(s)$
Authors: Zhang Weicun
Published: September 2022

Based on the Hadamard product $\xi(s)= \xi(0)\prod_{\rho}(1-\frac{s}{\rho})$, a new expression of $\xi(s)$ is obtained by paring $\rho$ and $\bar{\rho}$ $$\xi(s)=\xi(0)\prod_{i=1}^{\infty}\Big{(}\frac{\beta_i^2}{\alpha_i^2+\beta_i^2}+\frac{(s-\alpha_i)^2}{\alpha_i^2+\beta_i^2}\Big{)}^{d_{i}}$$ where $\xi(0)=\frac{1}{2}$, $\rho_i=\alpha_i+j\beta_i$ and $\bar{\rho}_i=\alpha_i-j\beta_i$ are complex conjugate zeros of $\xi(s)$, $0<\alpha_i<1$ and $\beta_i\neq 0$ are real numbers, $d_i\geq 1$ are the multiplicities of $\rho_i$, $\beta_i$ are in order of increasing $|\beta_i|$, i.e., $|\beta_1|\leq|\beta_2|\leq|\beta_3|\leq \cdots$. Then we have, by the functional equation $\xi(s)=\xi(1-s)$, that $$\xi(0)\prod_{i=1}^{\infty}\Big{(}\frac{\beta_i^2}{\alpha_i^2+\beta_i^2}+\frac{(s-\alpha_i)^2}{\alpha_i^2+\beta_i^2}\Big{)}^{d_{i}} =\xi(0)\prod_{i=1}^{\infty}\Big{(}\frac{\beta_i^2}{\alpha_i^2+\beta_i^2}+\frac{(1-s-\alpha_i)^2}{\alpha_i^2+\beta_i^2}\Big{)}^{d_{i}}$$ i.e., $$\prod_{i=1}^{\infty}\Big{(}1+\frac{(s-\alpha_i)^2}{\beta_i^2}\Big{)}^{d_{i}}=\prod_{i=1}^{\infty}\Big{(}1+\frac{(1-s-\alpha_i)^2}{\beta_i^2}\Big{)}^{d_{i}}$$ which, by Lemma 3, is further equivalent to $$(s-\alpha_i)^2=(1-s-\alpha_i)^2, i =1,2,3,...\infty$$ Comparing the like terms of the above polynomial equations, we have $$\alpha_i= \frac{1}{2}, i =1,2,3,...\infty$$ Thus, we conclude that the Riemann Hypothesis is true.

O objetivo desse estudo compreende na utilização de resíduos sólidos industriais quanto à melhoria das propriedades mecânicas dos compósitos cimentícios. Para tanto, foi avaliado a incorporação do pó de “brita” granítica e pó de mármore na confecção de compósitos à base de cimento, substituindo parcialmente o agregado miúdo natural em teores de 50% e 100%. Para isso, foram realizados ensaios de caracterização dos agregados, além da avaliação da resistência à compressão axial dos corpos-de-prova. Os resultados evidenciaram que as misturas contendo 50% de agregado reciclado confere ao material uma resistência à compressão de 29,09 MPa, ou seja, 4% superior quando comparado com as misturas de referência, tornando os resultados satisfatórios, demonstrando a viabilidade dos agregados reciclados em peças de concreto

Published: September 2022

In Indonesia, one of the sources of regional livestock genetic diversity is the kampung chicken. This study aimed to assess the development and reproductive potential of F1 Kampung Unggul Balitbangtan (KUB) crosses (KUB roosters with different types of combs crossed to layer chickens). This research was conducted at a private chicken company in Gunungkidul regency using 40 KUB roosters and 320 layer chicks. The KUB roosters were separated into four groups based on their comb types: single, walnut, and double. Each set of ten males was housed in a single cage, with a male-to-female ratio of one to eight (male and female). Observed reproductive variables included egg weight (EW), hatch weight (HW), fertility, hatchability, number of eggs, number of day-old chicks (DOCs), and number of saleable chicks. The body weight (BW) of the offspring at ages ranging from DOC, 4, 8, to 12 weeks of age is one measure of their growth characteristics. The analysis of variance using a one-way design and the DMRT test were performed to describe the difference in growth and reproductive performance across groups. As a result, each comb type revealed a significant difference in EW, HW, fertility, hatchability, egg and chick production, DOC, and saleable chick production (P<0.05). Compared to other combs, the single comb performed the best in terms of EW, HW, fertility, number of eggs, and number of DOC. The most hatchable and sellable chicks were from walnut comb. Therefore, comb size has a positive correlation with chicken reproduction and productivity. Comb type groups have no effect on BW at 12 weeks (P>0.05), while they significantly affect BW for DOC at 4 and 8 weeks (P<0.05). The rose comb shows BW at its maximum point. In conclusion, the rose comb has the biggest body weight and the single comb has the best reproductive performance in comparison to other comb types.

Authors: Arellano Maria Patricia , Purnamasari Listya , Dela Cruz Joseph
Published: September 2022

The study was conducted to evaluate the effects of citric acid and mannanase feed supplementation on the growth performance of broiler chickens. Three hundred twenty day-old unsexed Cobb broiler chicks from a commercial hatchery plant were used in the study. The chicks were randomly assigned to four treatment groups following a completely randomized design. The following treatment groups were used: T1: Control, T2: 3% (w/w) Citric Acid supplementation, T3: 80 ppm β-Mannanase supplementation, and T4: 3% (w/w) Citric Acid and 80 ppm β-Mannanase supplementation. The supplementation of citric acid and mannanase significantly improves the growth performance of broiler chickens. Body weight and body weight gain were significantly higher (P<0.05) in the citric acid and β-mannanase combination group compared to all the treatment groups. The evaluation of feed intake revealed that T3 and T4 had significantly lower (P<0.05) feed intake than the other groups. The combination of citric acid and β-Mannanase also resulted in a significantly more efficient (P<0.05) feed conversion ratio. No mortality was observed during the experiment. It may be concluded that the supplementation of citric acid and β- mannanase resulted in a better performance in broilers.

Authors: Talwar Abhinav , Bai Jennifer , Wester James R. , Attar Samer , Peabody Terrance D. , Ko Jason H.
Published: September 2022

Case:

Distal radius reconstruction after giant cell tumor (GCT) resection is typically performed with free fibular flaps when a vascularized bone is needed. However, vascularized fibular flaps are contraindicated in patients with peroneal artery variants. We present 2 patients with GCTs of the radius and bilateral peronea arteria magna who underwent resection with wrist fusion using an allograft bone and vascularized free medial femoral condyle periosteal flaps. Both patients had excellent outcomes with minimal postoperative morbidity.

Conclusion:

Allograft bone with vascularized medial femoral condyle periosteal flaps is an effective option for reconstructing distal radius defects after GCT resection when conventional methods fail.

Authors: Yarbrough Ben , Chan Peter Y.W. , Tan Virak
Published: September 2022

Case:

A 57-year-old man presented with pain and paresthesia in both hands and was diagnosed with pronator teres syndrome. Surgical decompression of the left elbow and forearm revealed the median nerve in an unusual anatomic location, specifically running within the pronator teres muscle.

Conclusion:

Anatomic anomalies of the pronator teres muscle and the path of the median nerve have been described. However, there are no reports of the median nerve entering and traveling within the pronator teres. Surgeons should be aware of this anomaly to avoid potential iatrogenic injury when performing an anterior surgical approach to the elbow and proximal forearm.

Published: September 2022

This study aimed to find an appropriate model of autonomous self-finance management in primary health care (PHC) to enhance workers' satisfaction. This was a cross-sectional study in which data were collected through self-administered questionnaires from 204 workers in ten Regional Public Service Agency for Primary Health Care (RPSAPHC)/Badan Layanan Umum Daerah Pusat Kesehatan Masyarakat (BLUD Puskesmas) in Tangerang District, Banten Province, Indonesia using the partial least squares and structural equation model (PLS-SEM). A total of 73 indicators were used to examine the PHC transformation process to enhance workers' satisfaction. The indicators were grouped into three variables depending on workers' satisfaction: intrinsic, extrinsic, and general satisfaction. In addition, there were five independent variables: financial accountability, generating income, structuring human resources, increasing service quality, and consumer satisfaction. Model autonomy was reflected by all the indicators (cross-loading > 0.70, Cronbach’s alpha > 0.70, average variance extracted > 0.5) affecting workers’ satisfaction (path coefficient = 0.196, p-value = 0.002). The management should apply five indicators (financial accountability, increasing income, structuring human resources, improving service quality, and customer satisfaction) affecting workers' satisfaction to transform the PHC.

Published: September 2022

The prevalence of stunting in Indonesian children aged 0-23 months is a public health problem caused by direct and indirect factors. This study aimed to discover the path of the relationship between various risk factors and the stunting prevalence of ≥30% in 165 districts/cities in Indonesia. Data were obtained from the 2018 National Basic Health Research, National Socioeconomic Survey, and the Statistics Indonesia with a cross-sectional approach. The secondary data on stunting and risk factors were aggregated at the district/city level from individual data; children aged 0-23 months. The path analysis used to determine a stunting prevention model showed that antenatal care at the district/city level decreased stunting rates by at least 2.56% (b = -0.16; p-value = 0.04). A contraceptive user at the district/city level decreased stunting rates by 2.25% (b = -0.15; p-value = 0.05), and handwashing with soap at the district/city level by5.76%, (b = -0.24; p-value = 0.003). Antenatal care, contraceptive use, and handwashing with soap contributed to the reduction of stunting prevalence by18.18%. The study results suggested that districts/cities can play an important role in reducing stunting.

The SARS-CoV-2 transmission dynamics in low- and middle-income countries remain poorly understood. This study aimed to estimate the SARS-CoV-2 antibodies seroprevalence in Jakarta, Indonesia, and to increase knowledge of SARS-CoV-2 transmission in urban settings. A population-based serosurvey among individuals aged one year or older was conducted in Jakarta. Employing a multistage sampling design, samples were stratified by district, slum, and non-slum residency, sex, and age group. Blood samples were tested for IgG against three different SARS-CoV-2 antigens. Seroprevalence was estimated after applying sample weights and adjusting for cluster characteristics. In March 2021, this study collected 4,919 respondents. The weighted estimate of seroprevalence was 44.5% (95% CI = 42.5-46.5). Seroprevalence was highest among adults aged 30-49 years, with higher seroprevalence in women and the overweight/obese group. Respondents residing in slum areas were 1.3-fold more likely to be seropositive than non-slum residents. It was estimated that4,717,000 of Jakarta's 10.6 million residents had prior SARS-CoV-2 infection. This suggests that approximately 10 infections were undiagnosed/underreported for every reported case. About one year after the first COVID-19 case was confirmed, close to half of Jakarta's residents have been infected by SARS-CoV-2.

Spatial analysis in public health has become a common method used by researchers to understand the distribution of public health aspects related to the surrounding environment. It can also be used to analyze individual information in the form of a dot and the location or line of aggregated information in a specific area of study. Another benefit is the possibility of using different data sources to be analyzed in one statistical model analysis, as long as the identification area is sufficiently clear as a key variable. Spatial analysis can show an object's distribution on a locational map and explain the distribution type, whether random, cluster, or uniform. The statistical analysis model can also develop different risk factors for each region of the research area. A specific model sometimes explains how to treat health issues differently in a specific location and can be used as an alternative approach to dealing with an intervention plan for public health issues based on specific local phenomena.

A pandemia da Covid-19 trouxe implicações para a saúde física e mental da população, com impacto acentuado para os profissionais da saúde. A relevância do suporte psicológico para o enfrentamento das consequências da pandemia evidenciou a necessidade de disponibilizar modelos de intervenção que possibilitem a compreensão das contingências em vigor e o desenvolvimento de repertórios comportamentais apropriados para o contexto da crise. O presente artigo descreve uma rede de apoio psicológico para promover a saúde mental de pessoas afetadas pela Covid-19. O projeto contou com aproximadamente 100 colaboradores(as) distribuídos(as) em seis frentes de trabalho. Cada frente de trabalho contava com docentes da universidade, discentes de graduação e pós-graduação, bem como colaboradores voluntários. Foram atendidas 146 pessoas, como profissionais de saúde; pacientes diagnosticados com Covid-19, seus familiares e amigos; bombeiros; policiais e alunos de graduação. Antes e depois da intervenção, os clientes responderam a dois instrumentos: o Outcome Questionnaire e a Escala Hospitalar de Ansiedade e Depressão. Os resultados apontam que houve redução dos escores de todos os fatores/domínios avaliados, mas as diferenças foram pequenas, principalmente em relação àqueles em que os escores iniciais eram levemente superiores ao ponto de corte entre valores clínicos e não clínicos. O projeto produziu diversos recursos psicoeducativos compartilhados com os clientes e divulgados nas redes sociais. Além da rede de apoio psicológico à população em geral, o projeto permitiu a criação de uma rede de apoio entre profissionais que atuavam na área de saúde mental e os capacitou para atuação num contexto de crise.

Cotranscriptional folding of RNA is a fundamental self-assembly process of nature, important for the biological assembly of complex molecular machines like the ribosome. Inspired by this folding process, we developed the cotranscriptional RNA origami design method to efficiently produce RNA nanostructures by enzymatic synthesis, advantageous for large-scale production in vitro or expression in vivo. However, advancing this technology further will require high-resolution characterization and a better understanding of the cotranscriptional folding process. Here, we use cryogenic electron microscopy to study a panel of RNA origami structures at local resolutions up to 3.4 Å, revealing details of kissing loop and crossover structural modules used to compose RNA origami. The derived structural parameters are used to reduce internal strain and global twist to obtain more ideal shapes. In three-dimensional bundle designs, we discover a novel kinetic folding trap that forms during cotranscriptional folding, and is only released 6-8 hours after transcription. Finally, pushing both scale and complexity, we design the first multi-domain RNA origami and characterize the conformational variability of its domains by individual particle electron tomography. Our results improve understanding of RNA structure, dynamics, and folding, providing a basis for future applications of cotranscriptional folding in RNA medicine and synthetic biology.
Direction-Guided Two-Stream Convolutional Neural Networks for Skeleton-Based Action Recognition

In skeleton-based action recognition, the approach of treating skeleton data as pseudo-images using convolutional neural networks (CNN) has proven to be effective. However, among the existing CNN-based approaches, most of them focus on modeling information at the joint-level ignoring the size and direction information of the skeleton edges, which play an important role in action recognition, and these approaches may not be optimal. In addition, combining the directionality of human motion to portray the motion variations information of the action, which is more natural and reasonable for action sequence modeling, is rarely considered in existing approaches. In this work, we propose a novel direction-guided two-stream convolutional neural networks (DG-2sCNN) for skeleton-based action recognition. On the first stream, our model focuses on our defined edge-level information (including edge and edge\_motion information) with directionality in the skeleton data to explore the spatio-temporal features of the action. On the second stream, since the motion is directional, we define different skeleton edge directions and extract different motion information (including translation and rotation information) in different directions in order to better exploit the motion features of the action. Besides, we propose the description of human motion inscribed by a combination of translation and rotation, and explore the way they are integrated. We conducted extensive experiments on two challenging datasets, NTU-RGB+D 60 and NTU-RGB+D 120, to verify the superiority of our proposed method over state-of-the-art methods. The experimental results demonstrate that the proposed direction-guided edge-level information and motion information complement each other for better action recognition.

Coal occupies an absolute advantage in the primary energy structure of China. However, the production of coal poses a serious threat to the ecological environment and human health. In order to quantify the environmental impact of coal mining, this study used the life cycle assessment (LCA) method to analyse the life cycle of coal mining from the cradle- to-gate. Midpoint results based on ReCiPe 2016 indicated that coal mining had a remarkable impact on human carcinogenic toxicity, marine ecotoxicity, freshwater ecotoxicity, fossil resource scarcity, and human non-carcinogenic toxicity. The contribution analysis revealed that material production was identified as the main cause of environmental impacts, followed by energy consumption and process emissions. Steel consumption, electricity production and wastewater discharge were identified as key environmental pollution processes. In addition, specific environmental pollution substances and their contributions were recognized from the source, and sensitivity analysis between key processes and key impact categories was carried out. At the endpoint level, coal mining led to the most damage to human health, followed by ecosystems and resources. This study is of reference significance in guiding the construction of green mines and achieving sustainable development of coal resources.

Background This meta-analysis aimed to assess and systematically investigate the efficacy of drug-loaded gel adjuncts in the treatment of periodontitis based on relevant literature. Methods Six databases including the China National Knowledge Infrastructure, WanFang Data, VIP Chinese Science and Technology Periodical Database, China Biology Medicine disc, Cochrane library, PubMed, and Web of Science were searched from the establishment of the database until December 2021 for randomized controlled trials (RCTs) that studied the application of drug-loaded gel in periodontitis treatment. The meta-analysis was conducted using Stata 15.0 and Review Manager 5.4 for articles that met the criteria. Results The study included nine RCTs involving 706 participants. Periodontal probing depth (PPD) and clinical attachment level (CAL) were the primary and secondary outcomes, respectively. The subgroup analyses performed for PPD (standardized mean difference [SMD] = 0.59, 95% confidence interval [CI]=[0.44, 0.73], I2 = 48.0%, p = 0.05) and CAL (SMD = 0.58, 95% CI=[0.34, 0.82], I2 = 61.0%, p = 0.005) of follow-up period revealed that the heterogeneity (p) among groups of each indicator is 0.98 and 0.96, respectively. The gel component was analyzed as another subgroup factor, reflected by heterogeneity (p = 0.23) among groups and Egger test (p = 0.794) in PPD, while the results of those in CAL were 0.1 and 0.079, respectively. Conclusion The application of drug-loaded gel as an adjunctive therapy for periodontitis resulted in effectively reduced PPD and promoted CAL recovery, providing an evidence-based improvement in efficacy, security, and rational use for clinical drug therapy instruction for periodontitis.

The objective of this study was to understand the perception of entrepreneurs based on their business model related to the connection of the Amazon brand. There is a need to present an entrepreneurial perspective on the brand´s changes and their long-term relationships between the Forest and the environmental sustainability on the Brazilian Amazon. The study consisted of semi-structured interviews with 1 out of 7 companies operating in the Amazon region. Brands that develop sustainable businesses in the Brazilian Amazon, with their brand equity based on the region's environmental responsibility, brought an understanding that a full performance of sustainable activities depends on the performance of three agents: entrepreneurs, native peoples and management. Entrepreneurs perceive a greater valuation of their products associated with the sustainability of the Amazon introduced in the brand experience by the customer.

Published: September 2022

A polymer-modified cement formulation with self-healing capability at ambient temperature is reported. The polymer used is a copolymerization product from the crosslinking reaction between N, N-methylene-bis-acrylamide (MBA) and 1,4-butanediamine (BDA) (MBA-BDA). Results show that the added polymer homogeneously distribute in the cement matrix without phase separation or water segregation. The polymer-modified cement has better workability than conventional cement and self-healing capability as demonstrated by the recovery of compressive strength after multiple damage/healing events. From 13C NMR data a mechanism for self-healing of MBA-BDA-modified cement is proposed based on multiple hydrogen bonding interactions between the oxygen of the carbonyl in the polymer and the hydrogen of the calcium silicate hydrates of cement. Unlike any other polymer-cement technologies reported in the open literature, such as cement modified with superabsorbent polymers or encapsulated polymers where fractures are filled without any apparent chemical bond formation, this self-healing polymer-modified cement represents a true self-healing cement formulation since chemical bonds are formed between the polymer and the surface of a crack restoring the structural integrity of cement as demonstrated by its multiple self-healing capability. To the best of our knowledge, this is the first polymer-modified cement technology with true self-healing capability at ambient temperature.

Graves' disease (GD) is the leading cause of hyperthyroidism in pediatric patients. Radioiodine therapy (RAIT) is widely used to treat GD, however, the predictors of efficacy of RAIT in childhood and adolescence are still not completely clear. Our purpose was to determine the most significant predictors of efficacy of RAIT in pediatric patients. The study enrolled 144 patients (124 females; 20 males) aged 8 to <18 years old who received the primary dosimetry-guided RAIT for GD. The parameters analyzed included gender, age, thyroid volume according to ultrasound examination before and 12 months after treatment, thyroid stimulating hormone (TSH), free triiodothyronine (FT3) free thyroxine (FT4), TSH receptor antibodies (TRAB) levels at baseline and twelve months after RAIT, 10-20-Min 99mTc thyroid uptake (%), maximum thyroid 131I uptake (%), specific 131I uptake (MBq/g) and therapeutic 131I activity (MBq). Fisher's exact test, Mann-Whitney U-test, Wilcoxon signed–rank test, ROC–analysis and Youden index were used for statistical analysis. Six months after RAIT, hypothyroidism was achieved in 119 (82.6%) patients, euthyroid state was achieved in 6 (4.2%), and hyperthyroidism persisted in 19 (13.2%). Thyroid volume decreased from 17.6 [14.6; 24.1] to 9.25 [7.62; 13.34] mL 12 months after the treatment (p<0.001). The main predictor that showed a statistically significant difference between the groups of patients who achieved and did not achieve remission of GD hyperthyroidism after RAIT was the initial thyroid volume. Using Youden index the optimal cut-off point of the initial thyroid volume in 45.4 ml was determined.Conclusion: The efficacy of the dosimetry-guided RAIT in pediatric patients with GD was 82.6% after 12 months, and one of the major predictors of RAIT success was an initial smaller thyroid volume.
