The application value of spectral CT venography in the display and staging of deep venous thrombosis in the lower extremity / 实用放射学杂志

Objective To investigate the application value of spectral computed tomography venography(CTV)in the display and staging of deep venous thrombosis(DVT)in the lower extremity.Methods Eighty-two patients with CTV were selected and ran-domly divided into group A(42 patients)and group B(40 patients).Group A:tube voltage 120 kVp.Group B:gemstone spectral ima-ging(GSI)mode,reconstruction of 50 keV and iodine(water)maps.The CT and standard deviation(SD)values of the veins were measured,signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated in 120 kVp images of group A and in 50 keV images of group B.Two observers scored the image quality of the 2 groups subjectively,and Kappa test was used to examine the con-sistency.Based on the duration from the occurrence of clinical symptoms,the DVTs were classified.The CT values and iodine con-centration(IC)of DVT were measured in the 120 kVp images of group A and in the iodine(water)maps of group B,respectively.The receiver operating characteristic(ROC)curve was drawn to compare the effectiveness of CT values and IC in diagnosing DVT staging.Results CT values,SNR,and CNR of veins in group B were higher than those in group A(P<0.05).The subjective scores of the two groups were consistent(Kappa=0.926-0.955,P<0.05).The score for the display of veins and thrombus clarity in group B was 5(4,5),which was better than the score of 4(3,4)in group A(P<0.05).The efficiency of IC in diagnosing DVT staging[area under the curve(AUC)=0.973]was better than that of CT values(AUC=0.891).Conclusion The spectral CTV can improve the contrast of lower extremity deep veins and the clarity of thrombus,and can provide more objective indicators for the diagnosis of thrombus staging,which is conducive to accurate clinical diagnosis and treatment.

Climate change-induced degradation of expert range maps drawn for kissing bugs (Hemiptera: Reduviidae) and long-standing current and future sampling gaps across the Americas

BACKGROUND Kissing bugs are the vectors of Trypanosoma cruzi, the etiological agent of Chagas disease (CD). Despite their epidemiological relevance, kissing bug species are under sampled in terms of their diversity and it is unclear what biases exist in available kissing bug data. Under climate change, range maps for kissing bugs may become less accurate as species shift their ranges to track climatic tolerance. OBJECTIVES Quantify inventory completeness in available kissing bug data. Assess how well range maps are at conveying information about current distributions and potential future distributions subject to shift under climate change. Intersect forecasted changes in kissing bug distributions with contemporary sampling gaps to identify regions for future sampling of the group. Identify whether a phylogenetic signal is present in expert range knowledge as more closely related species may be similarly well or lesser understood. METHODS We used species distribution models (SDM), specifically constructed from Bayesian additive regression trees, with Bioclim variables, to forecast kissing bug distributions into 2100 and intersect these with current sampling gaps to identify priority regions for sampling. Expert range maps were assessed by the agreement between the expert map and SDM generated occurrence probability. We used classical hypothesis testing methods as well as tests of phylogenetic signal to meet our objectives. FINDINGS Expert range maps vary in their quality of depicting current kissing bug distributions. Most expert range maps decline in their ability to convey information about kissing bug occurrence over time, especially in under sampled areas. We found limited evidence for a phylogenetic signal in expert range map performance. MAIN CONCLUSIONS Expert range maps are not a perfect account of species distributions and may degrade in their ability to accurately convey distribution knowledge under future climates. We identify regions where future sampling of kissing bugs will be crucial for completing biodiversity inventories.

Groundwater carbonate and bicarbonate ranged from 0.01 to 0.62 m mol-1 and 6.35 to 10.24 mmol-1 respectively. The dug well, bore well and tube well water RSC ranged from 0.70 to 1.25 mmol-1.Conclusion: This extensive study provides helpful insights into the regional variability of physical and chemical properties in both soil and water with help of soil fertility maps, providing better understanding of soil fertilizer input and environmental conditions in the Tungi watershed.

Field Evaluation of Site Specific Drip Fertigation in Tomato

Evaluation of site specific drip fertigation system based on GIS integrated nutrient status maps was conducted at Instructional Farm, KCAET, Tavanur, Malappuram, Kerala. Using the spatial variability maps of the soil nutrients, two test plots, one from high fertility zone and one from low fertility zone were identified with the help of GPS for raising the tomato crop. The experimental plot was laid out in a Completely Randomized Design (CRD) with four treatments and four replications. The results showed an increase in yield and growth parameters under site specific drip fertigation treatment in low fertility area due to the adequate fertiliser application than general recommendation. In high fertility area, reduction of fertilizer to site specific requirements has produced almost similar result of general recommendation which indicates that site specific dose was sufficient to produce optimum yield from the crop. Site specific drip fertigation helped to achieve a higher water and nutrient use efficiency with a high economic return of agricultural produce. From this study, it could be concluded that, instead of going with blanket nutrient recommendation, a site specific nutrient recommendation may help the farmers who want to achieve higher profit from unit land area by using optimum inputs, thereby reducing environmental stress due to over fertilizer application.

Os ciclos de engajamento no trabalho de servidores públicos federais / Los ciclos de compromiso laboral de los servidores públicos federales / The work engagement cycles of federal civil servants

Resumo Servidores públicos têm diferentes níveis de engajamento no trabalho ao longo da vida laboral. Essas variações, denominadas "ciclos de engajamento no trabalho", ocorrem graças aos recursos disponíveis e às demandas do ambiente de trabalho. Diante disso, o presente artigo busca descrever os ciclos de engajamento no trabalho de servidores públicos federais com base em suas histórias de vida profissional, evidenciando demandas e recursos relevantes do ambiente ocupacional na trajetória dessas pessoas. Usando o modelo job demands-resources (JD-R) e a metodologia de mapas cognitivos, foi possível identificar um ciclo positivo do engajamento no trabalho, um ciclo reforçador - relacionado com oportunidades e valorização - e dois ciclos de desequilíbrio, um ligado à produtividade disfuncional e, outro, à descontinuidade administrativa. A análise dos ciclos de engajamento permitiu identificar recursos do ambiente de trabalho que interferem de diferentes maneiras no engajamento de servidores públicos. Por fim, foi utilizado o conceito de "ciclo de enfrentamento" como subsídio de políticas para servidores desengajados.

Resumen Los servidores públicos tienen diferentes niveles de compromiso en el trabajo a lo largo de su vida laboral. Estas variaciones, llamadas ciclos de compromiso laboral, ocurren debido a los recursos disponibles y las demandas del entorno laboral. Frente a eso, el presente trabajo buscó describir los ciclos de compromiso en el trabajo de los servidores públicos federales a partir de sus historias de vida profesional, destacando demandas y recursos del ambiente laboral relevantes en la trayectoria laboral de esas personas. Utilizando el modelo job demands-resources (JD-R) y la metodología de mapas cognitivos, fue posible identificar un ciclo positivo de compromiso en el trabajo, un ciclo de refuerzo ‒ relacionado con oportunidades y apreciación ‒ y dos ciclos de desequilibrio, uno relacionado con la productividad disfuncional y el otro con la discontinuidad administrativa. El análisis de los ciclos de compromiso permitió identificar los recursos del ambiente de trabajo que interfieren de diferentes formas en el compromiso de los servidores públicos. Finalmente, se utilizó el concepto de "ciclo de afrontamiento" como base de las políticas para los servidores desinteresados.

Abstract Civil servants have different levels of work engagement throughout their working lives. These variations are the work engagement cycles, which occur based on available resources and work environment demands. This study describes the work engagement cycles of federal civil servants based on their professional life histories, highlighting the demands and resources of the work environment in their professional trajectory. Using the job demands-resources (JD-R) model and the cognitive maps methodology, it was possible to identify a positive cycle of work engagement, a reinforcing cycle (related to opportunities and appreciation), and two disequilibrium cycles, one related to dysfunctional productivity and the other to administrative discontinuity. The analysis of the engagement cycles allowed the identification of work environment resources that interfere in the engagement of public servants in different ways. Finally, the concept of "coping cycle" was used as a subsidy of policies for disengaged servants.

Three-dimensional morphology of lateral malleolar fractures of Danis-Weber type B and its clinical implications / 中华创伤骨科杂志

Objective:To characterize the 3-D morphology of lateral malleolar fractures of Danis-Weber type B, especially the distribution of fracture apexes, for formulation of 3-D maps of fracture lines which may facilitate the treatment of the fractures.Methods:A retrospective study was conducted to analyze the CT tomography data of 114 patients who had been operatively treated for lateral malleolar fractures of Danis-Weber type B at Department of Orthopaedic Surgery, Yangpu Hospital from January 2017 to May 2022. There were 46 males and 68 females with a mean age of 61.5 (51.8, 68.0) years. The morphology of distal bone blocks was measured and positions of fracture apexes were observed on 3-D CT reconstruction. According to the positions of apex, the fractures were divided into 4 types: type Ⅰ with the apex located on the lateral ridge, type Ⅱ with the apex located on the posterolateral side, type Ⅲ with the apex located on the posterior ridge, and type Ⅳ with the apex located on the medial side. CT images of all fractures were superimposed on a standard template to create 3-D fracture line maps.Results:In this cohort, there were 7 cases of type Ⅰ (6.1%, 7/114), 65 cases of type Ⅱ(57.0%, 65/114), 39 cases of type Ⅲ (34.2%, 39/114) and 3 cases of type Ⅳ (2.6%, 3/114). In 49 cases (43.0%, 49/114), the fracture apex was not located on the posterolateral fibula (so that a conventional posterolateral steel plate cannot compress the apex). In fracture morphology of the 114 patients, the anterior fracture height, posterior fracture height, vertical fracture length, inclination angle, spiral angle, and apex spiral angle were, respectively, (-6.22±4.62) mm, (27.23±12.32) mm, (33.45±11.89) mm, 56.9°±9.6°, 269.8°±37.1°, and 156.2°±24.0°. The anterior fracture height, posterior fracture height, vertical fracture length, inclination angle, spiral angle, and apex spiral angle in type Ⅲ were all significantly larger than those in type Ⅱ ( P<0.05). The 3-D fracture line maps indicated that the lines of type Ⅲ fracture were steeper than those of type Ⅱ fracture. Conclusions:Since the apexes are not located on the posterolateral fibula in nearly half of the Danis-Weber type B lateral malleolar fractures, a conventional posterolateral steel plate cannot provide an effective anti-glide role. The higher a fracture line, the closer the fracture apex is to the posteriomedial fibula (posterior ridge and medial side). Fractures of type Ⅲ and type Ⅲ often indicate greater injury violence and more accompanying injuries.

Case Report: Arterial Spin Labeling Perfusion MRI Contribution for Clinical Implementation of Brain Disease

@#Currently, ASL is widely used as an additional breakthrough sequence in MRI due to acquiring reliable results. The case report aims to prove the efficacy and effectiveness of a quantitative method of ASL sequence through the calculation of the cerebral blood flow (CBF) on CBF maps in different cases. ASL sequence has been done on four patients with different cases. Then, the authors put 2 regions of interest (ROI) for measurement in normal and different regions on CBF maps and then calculated the average value result from CBF maps. ASL has been proven as a reliable and breakthrough sequence in MRI for detecting brain disease with a non-invasive method through the calculation of CBF value. ASL should be used as an additional protocol in brain examinations because it allows radiologists to assess the significance of CBF values using a quantitative method that is more reliable and non-invasiv

Spatial variability of soil fertility under agroforestry system and native forest in eastern Amazonia, Brazil

The usage of spatial tools might be helpful in the optimization of decision-making regarding soil management, with technologies that assist in the interpretation of information related to soil fertility. Therefore, the present study evaluated the spatial variability of chemical attributes of the soil under an agroforestry system compared to a native forest in the municipality of Tomé-açu, Eastern Amazon, Brazil. Soil samples were performed at 36 points arranged in a 55 x 55 m grid. The soils were prepared and submitted to analysis in order to determine pH in H2O, exchangeable calcium, magnesium, potassium and aluminium, available phosphorus, potential acidity, organic matter, bases saturation and aluminium saturation. For each soil attribute, the spherical, gaussian and exponential models were adjusted. After the semivariograms fitting, data interpolation for assessment of spatial variability of the variables was performed through ordinary kriging. The spherical and gaussian models were the most efficient models in estimation of soil attributes spatial variability, in most cases. Most of variables presented a regular spatial variability in their respective kriging maps, with some exceptions. In general, the kriging maps can be used, and we can take them as logistical maps for management and intervention practices in order to improve the soil fertility in the study areas. The results principal components indicate the need for integrated management of soil chemical attributes, with localized application of acidity correctors, fertilizers and other types of incomes, using the spatial variability of these fertility variables.

Os árbitros do desejo e os enteados da natureza: controvérsias e ontologias sobre a categoria pedofilia em torno do DSM - 5 / The arbiters of desire and the stepchildren of nature: controversies and ontologies on the category pedophilia around the DSM - 5

Pedofilia é categoria originada na psiquiatria do final do século XIX para descrever uma espécie das denominadas perversões ou desvios sexuais, hoje parafilias, que conceitua a atração sexual de adultos por crianças pré-púberes. Tornou-se objeto de proibição e punição legal, ligada à categoria "abuso sexual infantil", e de repúdio social extremo, que configurou um dos pânicos morais/sexuais a partir das últimas décadas do século XX, no Brasil a partir do início dos anos 2000. No entanto, é notável constatar que a categoria, suas definições e características e as práticas científicas e políticas decorrentes (de pesquisa, terapêuticas, jurídicas) são objeto de uma ampla literatura e intensas controvérsias acadêmicas, clínicas e forenses em muitos países centrais da Europa e América do Norte. A tese visa delinear controvérsias recentes sobre o diagnóstico psiquiátrico "pedofilia" em torno da revisão do Diagnostic and Statistic Manual of Mental Disorders ­ DSM (Manual Diagnóstico e Estatístico de Transtornos Mentais) ­, da American Psychiatric Association, para a formulação do DSM-5, publicado em 2013, através de uma amostra de artigos de autores presentes nas propostas de revisão do diagnóstico, que expressam epistemologias, ontologias e deontologias diversas e em confronto. Os temas das controvérsias analisadas são a mudança do diagnóstico para "pedohebefilia", a permanência ou remoção das parafilias e da pedofilia do Manual e sua natureza enquanto "orientação", "interesse" ou "preferência" sexual. As vozes presentes nas controvérsias incluem psiquiatras, sexólogos, psicólogos, historiadores e uma organização de "pessoas atraídas por menores" (MAPs), nova designação utilizada por uma vertente do ativismo pedófilo. O delineamento das controvérsias é feito a partir de seus enquadramentos institucionais, políticos, morais, éticos e clínicos, configurando disputas significativas nestas posições e um consenso em torno do "combate" e prevenção ao abuso sexual infantil, categoria forte na quase totalidade das formulações. Apesar disso, há um dissenso ideológico e político sobre se a psiquiatria deve ser um enquadramento deste crime, se este não é, de fato, problema jurídico e penal e não médico, numa crítica à extensão das entidades diagnósticas para fins morais e políticos de contemplar a opinião pública e o aparato judicial. A psiquiatria forense é campo prevalente e determinante, embora não único, da permanência da categoria enquanto diagnóstico médico. Por outro lado, são abordadas as lutas, presentes nas controvérsias e no ativismo, pela desestigmatização desta condição da sexualidade, sua distinção da violência sexual e pelo estabelecimento de cidadania plena para os MAPs, que inclui o respeito de seus direitos no atendimento em serviços de saúde mental.

Pedophilia is a category originated in psychiatry in the late 19th century to describe a species of the so-called sexual perversions or deviations, nowdays paraphilias, which conceptualizes the sexual attraction by adults of pre-pubertal children. It turned the object of legal prohibition and punition, linked to the category of "child sexual abuse", and of extreme social rejection, that shaped one of the moral/sexual panics since the last decades of the 20th century, in Brasil since the early 2000 years. Nevertheless, it's noticeable to verify that the category, its definitions and features, and the scientific and political ensuing practices (of research, therapeutic, legal) are the object of a large literature and intense academic, clinical and forensic controversies in many central countries of Europe and North America. The thesis intends to outline recent controversies on the psychiatric diagnosis "pedophilia" around the revision of the Diagnostic and Statistic Manual of Mental Disorders ­ DSM - of the American Psychiatric Association and the elaboration of the DSM-5, published in 2013, through a sample of papers of acting authors in the proposals of the revision of the diagnosis, which express various epistemologies, ontologies and deontologies in dispute. The themes of the controversies under analysis are the change of the diagnosis to "pedohebephilia", the tenure or removal of paraphilias and pedophilia from the Manual and its nature as a sexual "orientation", "interest" or "preference". The figuring voices in the controversies include psychiatrists, sexologists, psychologists, historians and an organization of "minor-attracted people" (MAPs), new designation used by a branch of the pedophile activism. The delineation of the controversies is made through their institutional, political, moral, ethical and clinical frames, outlining noteworthy disputes in these positions and a consensus around the "combat" and prevention of child sexual abuse, strong category in almost the whole of the formulations. In spite of this, there is an ideological and political dissent on if psychiatry should be a frame to handle a crime, if this one is a juridical and penal problem and not a medical one, in a criticism of the extension of diagnostic entities for moral and political ends to comply with public opinion and the apparatus of Justice. Forensic psychiatry is a prevailing and decisive field, though not the only one, in the maintenance of the category as a medical diagnosis. On the other hand, the struggles, active in the controversies and activism, over the de-stigmatization of this condition of sexuality, its distinction from sexual violence and for the establishment of a full citinzenship for MAPs, including the respect of their rights of assistance in mental health services, are addressed.

Large-scale advances in SSR markers with high-throughput sequencing in Euphorbia fischeriana Steud

BACKGROUND: Euphorbia fischeriana Steud is a very important medicinal herb and has significant medical value for healing cancer, edema and tuberculosis in China. The lack of molecular markers for Euphorbia fischeriana Steud is a dominant barrier to genetic research. For the purpose of developing many simple sequence repeat (SSR) molecular markers, we completed transcriptome analysis with the Illumina HiSeq 2000 platform. RESULTS: Approximately 9.1 million clean reads were acquired and then assembled into approximately 186.3 thousand nonredundant unigenes, 53,146 of which were SSR-containing unigenes. A total of 76,193 SSR loci were identified. Of these SSR loci, 28,491 were detected at the terminal position of ESTs, which made it difficult to design SSR primers for these SSR-containing sequences, and the residual SSRs were thus used to design primer pairs. Analyzing the results of these markers revealed that the mononucleotide motif A/T (44,067, 57.83% of all SSRs) was the most abundant, followed by the dinucleotide type AG/CT (9430, 12.38%). Using 100 randomly selected primer pairs, 77 primers were successfully amplified in Euphorbia fischeriana Steud, and 79 were successfully amplified in three other related species. The markers developed displayed relatively high quality and cross-species transferability. CONCLUSIONS: The large number of EST-SSRs exploited successfully in Euphorbia fischeriana Steud for the first time could provide genetic information for research on linkage maps, variety identification, genetic diversity analysis, and molecular marker-assisted breeding.

Use of computational intelligence in the genetic divergence of colored cotton plants

The objective of this work was to analyze the genetic diversity using conventional methods and artificial neural networks among 12 colored fiber cotton genotypes, using technological characteristics of the fiber and productivity in terms of cottonseed and cotton fiber yield. The experiment was conducted in an experimental area located at Fazenda Capim Branco, belonging to the Federal University of Uberlândia, in the city of Uberlândia, Minas Gerais. Twelve genotypes of colored fiber cotton were evaluated, 10 from the Cotton Genetic Improvement Program (PROMALG): UFUJP - 01, UFUJP - 02, UFUJP - 05, UFUJP - 08, UFUJP - 09, UFUJP - 10, UFUJP - 11, UFUJP - 13, UFUJP - 16, UFUJP - 17 and two commercial cultivars: BRS Rubi (RC) and BRS Topázio (TC). The experimental design used was complete randomized block (CRB) with three replications. The following evaluations were carried out at full maturation: yield of cottonseed (kg ha-1) and the technological characteristics, which include, fiber length, micronaire, maturation, length uniformity, short fiber index, elongation and strength, using the HVI (High volume instrument) device. Genetic dissimilarity was measured using the generalized Mahalanobis distance and after obtaining the dissimilarity matrix, the genotypes were grouped using a hierarchical clustering method (UPGMA). A discriminant analysis and the Kohonen Self-Organizing Map (SOM) by Artificial Neural Networks (ANN's) were performed through computational intelligence. SOM was able to detect differences and organize the similarities between accesses in a more coherent way, forming a larger number of groups, when compared to the method that uses the Mahalanobis matrix. It was also more accurate than the discriminant analysis, since it made it possible to differentiate groups more coherently when comparing their phenotypic behavior. The methods that use computational intelligence proved to be more efficient in detecting similarity, with Kohonen's Self-Organizing Map being the most adequate to classify and group cotton genotypes.

Cross-country orienteering: interventions for the prevention and control of myopia among children and adolescents / 中国学校卫生

Abstract@#The visual health of children and adolescents in China has become a major issue that is relevant to the nation s present and its future. This article analyzed the value of map reading and searching for specific features during orienteering projects for myopia prevention and control. The findings suggest that orienteering exercises show good regulatory effects on eye muscles, effectively improve concentration, and help to stimulate mental activity and visual system. Targeted exercises, including scanning maps for specific features, is beneficial for myopia prevention and control. It is proposed that, by changing the teaching style of cross-country orienteering, teaching space, and teaching scene, exercises can be tailored to treat and relieve eye strain, as well as to prevent and control myopia, which is essential to promote the visual health of children and adolescents.

Regulation of EMT in lung cancer cells by interaction of Hsp90 and SIRT1 / 国际肿瘤学杂志

Objective:To investigate the interaction between heat shock protein 90 (Hsp90) and silent mating-type information regulation 2 homolog 1 (SIRT1) and evaluate its effect on epithelial-mesenchymal transition (EMT) of lung cancer A549 cells.Methods:EMT model was established by treating lung cancer A549 cells with 5 μg/L transforming growth factor-β1 (TGF-β1), which was used as TGF-β1 group, and the normal lung cancer A549 cells were used as control group. The interaction between Hsp90 and SIRT1 in lung cancer A549 cells was detected by immunocoprecipitation method. The expression of Hsp90 gene was silenced by RNA interference technique, and the cells were divided into TGF-β1 group, TGF-β1+ siRNA-Hsp90-neg group and TGF-β1+ siRNA-Hsp90 group. Transwell invasion assay was used to investigate the effect of the interaction of Hsp90 and SIRT1 on the invasion ability of lung cancer A549 cells. The expressions of Hsp90, SIRT1, E-cadherin and vimentin were detected by Western blotting. The effect of inhibiting Hsp90 expression on the stability of SIRT1 protein and EMT of lung cancer A549 cells was observed.Results:After 48 h induction with TGF-β1, EMT characteristics of lung cancer A549 cells were induced successfully. The relative expression levels of Hsp90 protein in the control group and TGF-β1 group were 0.45±0.05 and 1.31±0.06, respectively, the relative expression levels of SIRT1 protein were 0.29±0.04 and 0.95±0.08, respectively, and there were statistically signigicant differences ( t=10.98, P=0.018; t=7.39, P=0.028). The results of immunocoprecipitation showed that there was an interaction between Hsp90 and SIRT1 protein in lung cancer A549 cells. The relative expression levels of Hsp90 in the TGF-β1 group, TGF-β1+ siRNA-Hsp90-neg group and TGF-β1+ siRNA-Hsp90 group were 0.75±0.07, 0.63±0.06 and 0.23±0.05, respectively, and there was a statistically significant difference ( F=18.85, P=0.012). The relative expression levels of SIRT1 in the above three groups were 0.99±0.08, 0.97±0.12 and 0.35±0.05, respectively, and there was a statistically significant difference ( F=16.52, P=0.014). The expression levels of Hsp90 and SIRT1 in the TGF-β1+ siRNA-Hsp90 group were significantly lower than those in the TGF-β1 group ( P=0.019, P=0.016). The numbers of cells passing Matrigel in the above three groups were 378.13±27.70, 323.52±19.82 and 142.51±22.54, respectively, and there was a statistically significant difference ( F=27.35, P=0.022). The number of cells passing Matrigel in the TGF-β1+ siRNA-Hsp90 group was significantly less than that in the TGF-β1 group ( P=0.028). The relative expression levels of E-cadherin in the above three groups were 0.31±0.02, 0.34±0.04 and 0.63±0.05, respectively, and there was a statistically significant difference ( F=19.39, P=0.031). The relative expression levels of vimentin in the above three groups were 0.33±0.02, 0.27±0.05 and 0.09±0.03, respectively, and there was a statistically significant difference ( F=12.58, P=0.012). The expression level of E-cadherin in the TGF-β1+ siRNA-Hsp90 group was significantly higher than that in the TGF-β1 group ( P=0.017), while the expression level of vimentin was significantly lower than that in the TGF-β1 group ( P=0.023). Conclusion:Hsp90 interacts with SIRT1, and Hsp90 inhibition can lead to the decrease of SIRT1 protein level. Hsp90 may play a role of molecular chaperone to maintain the conformation stability of SIRT1, and the interaction between Hsp90 and SIRT1 may be one of the molecular mechanisms for the occurrence of EMT and the enhancement of invasion ability of lung cancer A549 cells.

Mapping Domain- and Age-Specific Functional Brain Activity for Children’s Cognitive and Affective Development / 神经科学通报·英文版

The human brain undergoes rapid development during childhood, with significant improvement in a wide spectrum of cognitive and affective functions. Mapping domain- and age-specific brain activity patterns has important implications for characterizing the development of children’s cognitive and affective functions. The current mainstay of brain templates is primarily derived from structural magnetic resonance imaging (MRI), and thus is not ideal for mapping children’s cognitive and affective brain development. By integrating task-dependent functional MRI data from a large sample of 250 children (aged 7 to 12) across multiple domains and the latest easy-to-use and transparent preprocessing workflow, we here created a set of age-specific brain functional activity maps across four domains: attention, executive function, emotion, and risky decision-making. Moreover, we developed a toolbox named Developmental Brain Functional Activity maps across multiple domains that enables researchers to visualize and download domain- and age-specific brain activity maps for various needs. This toolbox and maps have been released on the Neuroimaging Informatics Tools and Resources Clearinghouse website (http://www.nitrc.org/projects/dbfa). Our study provides domain- and age-specific brain activity maps for future developmental neuroimaging studies in both healthy and clinical populations.
