Abstract

Background: U.S. Hispanic/Latino construction workers constitute a large and historically underserved group in terms of smoking cessation services. Using formative research, we developed a worksite smoking cessation intervention tailored to the life/work circumstances of these workers. Aims: This study aims to examine the feasibility, acceptability, and potential efficacy of the developed intervention "Enhanced Care" (EC; one group behavioral counseling session provided around the food truck + fax referral to tobacco quitline [QL] + 8-week nicotine replacement treatment [NRT]) compared with "Standard Care" (SC; fax referral to tobacco QL + 8-week NRT) in a pilot, two-arm, cluster randomized controlled trial. Method: In collaboration with construction site safety managers, a sample of 17 construction sites (EC: nine sites/65 smokers; SC: eight sites/69 smokers) was enrolled. Participants received two follow-ups at 3 and 6 months after enrollment. Feasibility outcomes were enrollment rate, adherence to treatment, and 6-month retention rates. The primary efficacy outcome was 6 months prolonged abstinence verified by expired carbon monoxide <10 ppm. Results: Enrollment rate was high (85.9%). Six-month follow-up rates were acceptable (EC = 76.9%, SC = 66.6%). Adherence to treatment was better in the EC group (received worksite intervention: EC = 93.8%, SC = 88.4%; contacted by QL: EC = 49.2%, SC = 40.6%). Abstinence rates were 27.7% for the EC and 20.3% for the SC (p = 0.315). Discussion: The developed intervention was feasible and acceptable, and it substantially improved abstinence among Hispanic/Latino workers. The involvement of safety managers was essential to the implementation of the intervention. Training safety managers to deliver the intervention has great potential to implement a sustainable smoking cessation service in the construction sector.

Abstract

BackgroundWe characterized the whole transcriptome of circulating tumor cells (CTCs) in stage II-III breast cancer to evaluate correlations with primary tumor biology.MethodsCTCs were isolated from peripheral blood (PB) via immunomagnetic enrichment followed by fluorescence-activated cell sorting (IE/FACS). CTCs, PB, and fresh tumors were profiled using RNA-seq. Formalin-fixed, paraffin-embedded (FFPE) tumors were subjected to RNA-seq and NanoString PAM50 assays with risk of recurrence (ROR) scores.ResultsCTCs were detected in 29/33 (88%) patients. We selected 21 cases to attempt RNA-seq (median number of CTCs = 9). Sixteen CTC samples yielded results that passed quality-control metrics, and these samples had a median of 4,311,255 uniquely mapped reads (less than PB or tumors). Intrinsic subtype predicted by comparing estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) versus PAM50 for FFPE tumors was 85% concordant. However, CTC RNA-seq subtype assessed by the PAM50 classification genes was highly discordant, both with the subtype predicted by ER/PR/HER2 and by PAM50 tumors. Two patients died of metastatic disease, both of whom had high ROR scores and high CTC counts. We identified significant genes, canonical pathways, upstream regulators, and molecular interaction networks comparing CTCs by various clinical factors. We also identified a 75-gene signature with highest expression in CTCs and tumors taken together that was prognostic in The Cancer Genome Atlas and Molecular Taxonomy of Breast Cancer International Consortium datasets.ConclusionIt is feasible to use RNA-seq of CTCs in non-metastatic patients to discover novel tumor biology characteristics.

Abstract

A20 is a ubiquitin-editing enzyme that is known to regulate inflammatory signaling and cell death. However, A20 mutations are also frequently found in multiple malignancies suggesting a potential role as a tumor suppressor as well. We recently described a novel role for A20 in regulating the wnt-beta-catenin signaling pathway and suppressing colonic tumor development in mice. The underlying mechanisms for this phenomenon are unclear. To study this, we first generated A20 knockout cell lines by genome-editing techniques. Using these cells, we show that loss of A20 causes dysregulation of wnt-dependent gene expression by RNAseq. Mechanistically, A20 interacts with a proximal signaling component of the wnt-signaling pathway, receptor interacting protein kinase 4 (RIPK4), and regulation of wnt-signaling by A20 occurs through RIPK4. Finally, similar to the mechanism by which A20 regulates other members of the receptor interacting protein kinase family, A20 modifies ubiquitin chains on RIPK4 suggesting a possible molecular mechanism for A20's control over the wnt-signaling pathway.

Abstract

Objectives: Limited research exists on COVID-19 associated brain fog, and on the long-term cognitive and psychiatric sequelae in racially and ethnically diverse patients. We characterize the neuropsychological sequelae of post-acute COVID-19 in a diverse cohort and investigate whether COVID-19 clinical severity remains associated with brain fog and cognitive deficits approximately 2 years post infection. Methods: A cross-sectional study of patients with a history of COVID-19 hospitalization (March-September 2020). COVID-19 clinical severity was indexed using the National Early Warning Score 2 and a comprehensive neuropsychological tele-battery was administered 2 years post discharge. Pearson's r correlations assessed association, while independent sample t-tests examined group differences. Significant outcomes were further analyzed using multiple regression and ANCOVAs, adjusting for key covariates. Results: In 41 adult patients (19 female, 30 Hispanic, 13 Black, mean age of 65 (SD = 15), COVID-19 level of severity was associated with greater number of endorsed brain fog symptoms (Pearson's r =.34, 95% CI [.04,.59]), worse overall cognitive functioning (global cognition: r = -.36, 95% CI [-.61, -.05]) and reduced performance on an attention and working memory task (digit span backwards: r = -.41, 95% CI [-.66, -.09]) at 2-year follow-up. Brain fog symptoms most associated with COVID-19 severity included difficulty focusing (r =.46, 95% CI [.18,.67]), detached (r =.41, 95% CI [.12,.64]) and feeling sleepy (r =.40, 95% CI [.11,.63]). Patients' cognitive performance was generally below average (global cognition z-score: M = -.96, SD =.66), with group differences based on sex and ethnicity evidenced on individual cognitive tests. Discussion: This study emphasizes the importance of continued research on the long-term effects of COVID-19 infection on neuropsychological outcomes, particularly among underrepresented, health-disparate groups. Greater understanding of these associations could improve detection and treatment of those at increased risk of cognitive decline or impairment. [ABSTRACT FROM AUTHOR]

Abstract

This essay explores engagement with postindustrial landscapes and conceptions of nature at Hunters Point, a formerly vacant waterfront site in Queens, New York City. Chronicling and documenting a number of appropriations and transgressive practices at this postindustrial site, it argues for the necessity of vacant spaces within dense contemporary cities, like New York. Vacant or marginal spaces, particularly those on the water's edge, offer opportunities for environmental engagement that are not available in traditional or emerging parks and public spaces, and speak to basic human impulses or needs to convene with the natural environment in which we live.

Abstract

ilustraciones El formato coral (SATB) ha sido asociado con construcciones de género binarias durante mucho tiempo, esto ha generado una normalización en la asociación de registros vocales con el género de una persona; sopranos y altos son mujeres, tenores y bajos son hombres. En la actualidad la inclusión y la diversidad del género es un tema que no debería ignorarse, esta investigación es una invitación a la discusión del formato coral en su tradición, y como este podría adaptarse a la inclusión y la diversidad de género, aportando herramientas al director coral colombiano que van desde la comunicación, el uso del lenguaje inclusivo dentro y fuera del aula de clases, hasta la definición de conceptos propios de la comunidad LGBT. El escrito presenta una reflexión en torno a una comunidad que ha sido violentada, discriminada y marginada de muchos escenarios, buscando crear una inclusión desde el conocimiento, la conciencia y el respeto.

Abstract

Using a cultural landscape approach, this study examines all National Register of Historic Places (NRHP) sites in Ouachita Parish, Louisiana, located in the southern United States. The NRHP recognizes sites representative of “our” national heritage by listing them on this registry. From analysis of these records and related archival materials and observations garnered from field visits to select historic sites in the parish, this study interrogates the officially-designated memorial landscape of the American South. We find that preservation and reuse practices of NRHP-sites have engaged in racialized “purposeful forgetting” (Roberts 2020) and reinforced power relations while enabling the appropriation of Black, Indigenous, People of Color (BIPOC) labor and culture.

Abstract

BACKGROUND Metastatic breast cancer (MBC) and the circulating tumor cells (CTCs) leading to macrometastases are inherently different than primary breast cancer. We evaluated whether whole transcriptome RNA-Seq of CTCs isolated via an epitope-independent approach may serve as a surrogate for biopsies of macrometastases. METHODS We performed RNA-Seq on fresh metastatic tumor biopsies, CTCs, and peripheral blood (PB) from 19 newly diagnosed MBC patients. CTCs were harvested using the ANGLE Parsortix microfluidics system to isolate cells based on size and deformability, independent of a priori knowledge of cell surface marker expression. RESULTS Gene expression separated CTCs, metastatic biopsies, and PB into distinct groups despite heterogeneity between patients and sample types. CTCs showed higher expression of immune oncology targets compared with corresponding metastases and PB. Predictive biomarker (n = 64) expression was highly concordant for CTCs and metastases. Repeat observation data post-treatment demonstrated changes in the activation of different biological pathways. Somatic single nucleotide variant analysis showed increasing mutational complexity over time. CONCLUSION We demonstrate that RNA-Seq of CTCs could serve as a surrogate biomarker for breast cancer macrometastasis and yield clinically relevant insights into disease biology and clinically actionable targets.

Abstract

En el presente estudio se propone una metodología que cuantifique la capacidad de carga de un puente de concreto reforzado bajo distintas condiciones de deterioro en Colombia. Para esto se recopila modelos analíticos del estado del arte de materiales que calculan la difusión de agentes degradantes y el estado del material en distintas épocas del tiempo. Para calcular el deterioro de materiales se usó como parámetros de entrada la variación del estado atmosférico, el diseño del concreto y el detalle del acero de refuerzo del puente. La modelación se realizó con simulaciones de Monte - Carlo para considerar la variabilidad del estado del material y obtener distintos resultados en el tiempo. Finalmente, con los resultados de deterioro del material se calcula la capacidad de carga de un puente típico de concreto reforzado. This study proposes a methodology that quantifies the load carrying capacity of a reinforced concrete bridge under different deterioration conditions in Colombia. For this, analytical models of the state of the art of materials are compiled that quantify the diffusion of degrading agents and the state of the material in different periods of time. To calculate the deterioration of the materials, the variation of the atmospheric state, the concrete design, and the detail of the reinforcing steel of the bridge are used as input parameters. The modeling was carried out with Monte-Carlo simulations to consider the variability of the state of the material and obtain different results over time. Finally, with the material deterioration results, the load carrying capacity of a typical reinforced concrete bridge is calculated. Magíster en Ingeniería Civil Maestría

Abstract

In the present investigation, we evaluated the green synthesis of ZnO nanoparticles and their application as an antibacterial agent for textile substrates. The synthesis process involved the use of Azadirachta indica and Aloe vera extracts, and zinc acetate dihydrate as a metallic precursor. The synthesis of the nanoparticles was confirmed by UV-Vis spectrophotometry, Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (DRX), and Scanning Electron Microscopy (SEM). The efficiency of nanoparticles as a textile antibacterial agent was tested in a 100 % cotton textile functionalized by exhaustion. The textile was subjected to five and ten domestic washing cycles to analyze the durability of the nanoparticles. The antibacterial activity of the functionalized textile, with and without washing cycles, was determined by the ISO 20743:2007 standard against Staphylococcus aureus ATCC 6538 bacteria. We found that nanoparticles conferred strong antibacterial activity to the textile, and while there is a significant loss of nanoparticles with wash cycles, the remaining concentration is sufficient to maintain significant antibacterial activity up to ten cycles. We concluded that ZnO nanoparticles are promising candidates to be used as antibacterial agents in the textile industry, presenting antibacterial activity and being relatively easy to obtain by green synthesis using vegetal subtracts available in Antioquia., En la presente investigación se evaluó la síntesis verde de nanopartículas de óxido de zinc (ZnO) y su aplicación como agente antibacteriano para sustratos textiles. El proceso de síntesis implicó el uso de extractos de Azadirachta indica, Aloe vera, y acetato de zinc como precursor metálico. La síntesis de nanopartículas se confirmó mediante espectrofotometría UV-Vis, espectroscopia de infrarrojo con transformada de Fourier (FTIR), difracción de rayos X (DRX) y microscopía electrónica de barrido. La eficiencia de las nanopartículas como agentes antibacterianos en textiles se probó en uno de 100 % algodón funcionalizado por impregnación. Este fue sometido a cinco y diez ciclos de lavado doméstico para analizar la durabilidad de las nanopartículas. La actividad antibacteriana del textil funcionalizado, con y sin ciclos de lavado, se determinó mediante la norma ISO 20743:2007 contra la bacteria Staphylococcus aureus ATCC 6538. Se encontró que las nanopartículas confieren una actividad antibacteriana fuerte al textil y, aunque hay una pérdida importante del nanomaterial con los ciclos de lavado, la concentración remanente es suficiente para mantener una actividad antibacteriana significativa hasta los diez ciclos de lavado. Se concluye que las nanopartículas de ZnO son candidatas promisorias para ser empleadas como agentes antibacterianos en la industria textil, pues presentan actividad antibacteriana y son relativamente fáciles de obtener por síntesis verde con extractos de A. indica y A. vera, material vegetal de fácil acceso en el departamento de Antioquia.

Abstract

Trabajo final presentado por Daniel Campo para un Máster de la Universitat de Barcelona (UB), realizado bajo la dirección del Dr. David Casas y del Dr. Rafael Bartolomé del Institut de Ciències del Mar (ICM-CSIC), [EN] Multibeam bathymetry and more than 1519 nm of very high-resolution parametric profiles (TOPAS and ParasoundP-35) were used to characterize the recent morpho-sedimentary evolution of the Garrucha canyon system located in the Palomares continental margin (SW Mediterranean). For this purpose, unconventional seismic processing was performed to improve 784 nmof the parametric profiles that presented low-quality images.Three main echo-facies, (a) stratified (b) non-penetrative and (c) transparent were distinguished, mapped and interpretedin terms of sedimentaryprocesses, allowing the identification of several depositional, erosional and mass movement features distributed in the canyon domain and its margins. Upper-slope depositional systems, including contourite drifts, are interrupted by the tributaries of the Garrucha canyon system, which in turn, exhibits a network of gullies. Mass movement features (MTD) are distributed along the margin and are identified as the dominant sedimentary features in the continental slope on the canyon margins and walls.The most likely trigger of the near-surface slope failures described is the tectonic activity and the interaction of fluvio-marine processes, [ES] La evolución morfo-sedimentaria reciente del sistema de cañón de Garrucha localizado en el margen continental de Palomares (SO Mediterráneo), ha sido caracterizada mediante datos de batimetría multihaz y perfiles paramétricos de muy alta resolución (TOPAS y Parasound P-35). Debido a la escasa calidad de una parte de los perfiles paramétricos disponibles, unas 784 millas náuticas de perfiles se han procesado mediante un procedimiento no convencional pero aplicable a datos paramétricos. El análisis de los perfiles sísmicos ha permitido definir 3 tipos de eco-facies principales:(a) estratificada, (b) no-penetrativa y (c) transparente, así como su distribución en el área de trabajo. Esto interpretado en términos de procesos sedimentarios permitió delimitar los procesos deposicionales, erosivos e inestabilidades sedimentarias como los principales que definen el sistema de cañón de Garrucha. Los elementos deposicionales como los depósitos contorníticos presentes en el talud continental superior, se ven interrumpidos por el sistema de cañón que a su vez está afectado por elementos erosivos como cárcavas. Las inestabilidades sedimentarias (MTD) son los procesos dominantes tanto en los diferentes dominios del cañón como en los márgenes. La actividad tectónica y la interacción con procesos fluvio-marinos se han identificado como los principales detonantes (triggers) de la inestabilidad sedimentaria en la zona de estudio

Abstract

VII International Symposium on Marine Sciences (ISMS 2020), 1-3 July 2020 (Barcelona).-- 1 page, The 74 km long Almanzora-Alías-Garrucha canyon system is one of the most important submarine canyons located in the Palomares continental margin (SW Mediterranean Sea). The canyon head and upper course are constituted by several tributaries such as Almanzora, Garrucha, Cabrera and Alias canyons from N to S. During 3 recent oceanographic cruises, different multibeam echosounder datasets were merged and also an extensive network of parametric profiles was recorded to study the canyon. A total of 1519 nautical miles of parametric profiles (TOPAS and Parasound P-35, penetration < 150 m) were acquired in order to characterize the main morphological features and to map the eco-facies defining the deposits and sedimentary processes along the different canyon domains, included its margins.

Abstract

El cambio climático fácilmente podría ser el peor mal de nuestros tiempos y las consecuencias que este traería podrían ser devastadoras para la vida en nuestro planeta. Podemos entender como cambio climático la variación del clima atribuido directa o indirectamente a la actividad humana, ocasionando como resultado de esto, un aumento del nivel del mar, olas de calor, sequías, especies en extinción, Inestabilidad económica, entre otras. Para mitigar esta problemática se han creado algunos acuerdos a nivel mundial, de entre ellos el que posiblemente sea el más importante, serían los Objetivos de Desarrollo Sostenible (ODS) u Objetivos Mundiales; estos fueron acordados en 2015 como un llamado universal para poner fin a la pobreza, proteger el planeta y garantizar que todas las personas gocen de paz y prosperidad para 2030. Estos 17 componentes que conforman los ODS están articulados porque se reconoce que los resultados de unos, ya sean estos positivos o negativos afectaran los resultados de los otros. Además de esto es importante destacar que existen otros estudios que están íntegramente relacionados con los ODS, más concretamente nos referimos a los estudios sobre el medio ambiente y el cambio climático en general, estos estudios encajan en quizás un “marco de estudio” conocido como puntos de inflexión o tipping points, los cuales son nueve puntos críticos de no retorno que tendrán y tienen un gran impacto en el cambio climático. Para esta investigación nos enfocamos en 3 de los 17 componentes que conforman los ODS, los cuales son el 13. Acción por el clima, el 14. Vida submarina y el 15. Vida de ecosistemas terrestre, estos fueron seleccionados en base a que son los objetivos que más pueden afectar a los tipping points, entre más sea el desarrollo de estos aumentará la posibilidad de evitar las consecuencias del cambio climático. El motivo de redacción de este artículo es a modo de estado del arte a cerca de como los tipping points tienen un impacto a día de hoy, y a su vez el cómo estos podrían impactar en un futuro no muy lejano, no solo a un nivel nacional sino también de forma internacional, conociendo de paso qué medidas se están o se estarán aplicando tanto en Colombia como en el resto del mundo.

46. Parametric eco-facies mapping of The Garrucha Canyon System: Seismic processing and geological interpretation

Abstract

[EN] Multibeam bathymetry and more than 1519 nm of very high-resolution parametric profiles (TOPAS and ParasoundP-35) were used to characterize the recent morpho-sedimentary evolution of the Garrucha canyon system located in the Palomares continental margin (SW Mediterranean). For this purpose, unconventional seismic processing was performed to improve 784 nmof the parametric profiles that presented low-quality images.Three main echo-facies, (a) stratified (b) non-penetrative and (c) transparent were distinguished, mapped and interpretedin terms of sedimentaryprocesses, allowing the identification of several depositional, erosional and mass movement features distributed in the canyon domain and its margins. Upper-slope depositional systems, including contourite drifts, are interrupted by the tributaries of the Garrucha canyon system, which in turn, exhibits a network of gullies. Mass movement features (MTD) are distributed along the margin and are identified as the dominant sedimentary features in the continental slope on the canyon margins and walls.The most likely trigger of the near-surface slope failures described is the tectonic activity and the interaction of fluvio-marine processes, [ES] La evolución morfo-sedimentaria reciente del sistema de cañón de Garrucha localizado en el margen continental de Palomares (SO Mediterráneo), ha sido caracterizada mediante datos de batimetría multihaz y perfiles paramétricos de muy alta resolución (TOPAS y Parasound P-35). Debido a la escasa calidad de una parte de los perfiles paramétricos disponibles, unas 784 millas náuticas de perfiles se han procesado mediante un procedimiento no convencional pero aplicable a datos paramétricos. El análisis de los perfiles sísmicos ha permitido definir 3 tipos de eco-facies principales:(a) estratificada, (b) no-penetrativa y (c) transparente, así como su distribución en el área de trabajo. Esto interpretado en términos de procesos sedimentarios permitió delimitar los procesos deposicionales, erosivos e inestabilidades sedimentarias como los principales que definen el sistema de cañón de Garrucha. Los elementos deposicionales como los depósitos contorníticos presentes en el talud continental superior, se ven interrumpidos por el sistema de cañón que a su vez está afectado por elementos erosivos como cárcavas. Las inestabilidades sedimentarias (MTD) son los procesos dominantes tanto en los diferentes dominios del cañón como en los márgenes. La actividad tectónica y la interacción con procesos fluvio-marinos se han identificado como los principales detonantes (triggers) de la inestabilidad sedimentaria en la zona de estudio

Abstract

The 74 km long Almanzora-Alías-Garrucha canyon system is one of the most important submarine canyons located in the Palomares continental margin (SW Mediterranean Sea). The canyon head and upper course are constituted by several tributaries such as Almanzora, Garrucha, Cabrera and Alias canyons from N to S. During 3 recent oceanographic cruises, different multibeam echosounder datasets were merged and also an extensive network of parametric profiles was recorded to study the canyon. A total of 1519 nautical miles of parametric profiles (TOPAS and Parasound P-35, penetration < 150 m) were acquired in order to characterize the main morphological features and to map the eco-facies defining the deposits and sedimentary processes along the different canyon domains, included its margins. The parametric profiles have been processed after the deconvolution of the continuous 4 kHz Carrier wave pulse acquired using a source wavelet extracted from the data itself. Processing steps include automatically picking of the seafloor, burst noise removing, time-frequency noise attenuation, spherical divergence correction, butterworth and 2D spatial filtering. Finally, reflection strength (envelope of the signal) has been calculated and time-variant amplitude corrected for displaying and interpretation. Different sedimentary features such as bedforms, mass-movement deposits, erosive surfaces, fluid dynamic features and contourites have been defined. Most of tributaries show a progressive indentation and features observed in the upper courses are related to the erosive processes e.g. a dense network of dendritic gullies and minor scars and falls affecting the canyon walls. The seafloor of the southern margin is highly irregular defining an area that extends from 600 to 2240 mwd affected by a mass flows deposits composite. In contrast, the northern margin presents a set of nested concave-downward scars, with a W-E trend, and lengths of 2 to 8 km
