Psychiatry ,RC435-571 - Abstract
Introduction The Positive and Negative Syndrome Scale (PANSS) has been used as a universal instrument for clinical assessment of psychopathology in schizophrenia. Different studies have analyzed the factorial structure of this scale and have suggested a five-factor model: positive, negative, excited, depressive, and cognitive/disorganized factors. Two of the most used models are the Marder´s solution and the Wallwork´s one. Objectives The aim of this work was to study the correlations of the two cognitive factors (Marder and Wallwork) with a cognitive assessment performed with a standard cognitive battery, in a sample of patients with first psychotic episode of schizophrenia. Methods Seventy four patients with first psychotic episode of schizophrenia (26.9, SD:7.8 years old; 70.3% male) were included. The cognitive assessment was performed with the MATRICS Consensus Cognitive Battery (MCCB). The MCCB present seven cognitive domains: Speed of processing, Working memory, Attention/Vigilance, Verbal Learning, Visual Learning, Reasoning and Problem Solving, and Social cognition). Pearson correlations were performed between MCCB scores and Marder´s PANSS cognitive factor (P2, N5, G5, G10, G11, G13, G15) and Wallwork´s one (P2, N5, G11). Results Correlation between MCCB scores and cognitive factors of Marder and Wallwork can be seen in the table. Marder´s cognitive factor Wallwork´s cognitive factor Speed of processing r = -0.461; p

Geodiversity is recognized as one of the most important drivers of ecosystem characteristics and biodiversity globally. However, in the northern Neotropics, the contribution of highly diverse landscapes, environmental conditions, and geological history in structuring large-scale patterns of aquatic environments and aquatic species associations remains poorly understood. We evaluated the relationships among geodiversity, limnological conditions, and freshwater ostracodes from southern Mexico to Nicaragua. A cluster analysis (CA), based on geological, geochemical, mineralogical, and water-column physical and chemical characteristics of 76 aquatic ecosystems (karst, volcanic, tectonic) revealed two main limnological regions: (1) karst plateaus of the Yucatán Peninsula and northern Guatemala, and (2) volcanic terrains of the Guatemalan highlands, mid-elevation sites in El Salvador and Honduras, and the Nicaraguan lowlands. In addition, seven subregions were recognized, demonstrating a high heterogeneity of aquatic environments. Principal component analysis (PCA) identified water chemistry (ionic composition) and mineralogy as most influential for aquatic ecosystem classification. Multi-parametric analyses, based on biological data, revealed that ostracode species associations represent disjunct faunas. Five species associations, distributed according to limnological regions, were recognized. Structural equation modeling (SEM) revealed that geodiversity explains limnological patterns of the study area. Limnology further explained species composition, but not species richness. The influence of conductivity and elevation were individually evaluated in SEM and were statistically significant for ostracode species composition, though not for species richness. We conclude that geodiversity has a central influence on the limnological conditions of aquatic systems, which in turn influence ostracode species composition in lakes of the northern Neotropical region.

Geology ,QE1-996.5 - Abstract
The primary scientific objective of MexiDrill, the Basin of Mexico Drilling Program, is development of a continuous, high-resolution ∼400 kyr lacustrine record of tropical North American environmental change. The field location, in the densely populated, water-stressed Mexico City region gives this record particular societal relevance. A detailed paleoclimate reconstruction from central Mexico will enhance our understanding of long-term natural climate variability in the North American tropics and its relationship with changes at higher latitudes. The site lies at the northern margin of the Intertropical Convergence Zone (ITCZ), where modern precipitation amounts are influenced by sea surface temperatures in the Pacific and Atlantic basins. During the Last Glacial Maximum (LGM), more winter precipitation at the site is hypothesized to have been a consequence of a southward displacement of the mid-latitude westerlies. It thus represents a key spatial node for understanding large-scale hydrological variability of tropical and subtropical North America and is at an altitude (2240 m a.s.l.), typical of much of western North America. In addition, its sediments contain a rich record of pre-Holocene volcanic history; knowledge of the magnitude and frequency relationships of the area's explosive volcanic eruptions will improve capacity for risk assessment of future activity. Explosive eruption deposits will also be used to provide the backbone of a robust chronology necessary for full exploitation of the paleoclimate record. Here we report initial results from, and outreach activities of, the 2016 coring campaign.

Según la Organización de las Naciones Unidas para la Agricultura y la Alimentación, los cítricos dominan la producción mundial de todas las frutas. Por su posición geográfica, Ecuador tiene condiciones favorables de crecimiento para la producción de cítricos y la mayor parte del país tiene condiciones favorables para las plantas y sus relaciones con las condiciones ambientales. El objetivo de la presente investigación fue determinar la fenología reproductiva de la sutil de limón ( Citrus aurantifolia Swingle) bajo diferentes niveles de humedad del suelo.Un Asistente de Configuración de Base de Datos) usando un diseño de Bloque Completo Aleatorio aplicado y cuatro tratamientos y seis repeticiones se distribuyeron de la siguiente manera: tratamiento 1 [coeficiente de cultivo (Kc) 0.3], tratamiento 2 (Kc 0.5), tratamiento 3 (Kc 0,7) y tratamiento 4 (Kc 0,9). Se evaluó la calidad del fruto, peso de piel y pulpa, cantidad de semilla, contenido de jugo, grado Brix y diámetro polar y ecuatorial, y se ajustó la fenología a la codificación de la escala BBCH. No se encontraron diferencias estadísticamente significativas durante el estudio que resultaron de las lluvias que homogeneizaron todo el sustrato y mantuvieron la humedad del suelo.Establecimos que desde la fase fenológica de los primordios hasta la cosecha del fruto, hubo un intervalo de 138-140 d en el que el peso promedio del fruto (42. 62 g) fluctuó según el peso de la piel (7,65 g) , peso de la pulpa (34,73 g), número de semillas (5,05), cantidad de jugo (14,36 mL), grados Brix (5,5), diámetros polares y ecuatoriales (44,32 y 42, 12 mm, respectivamente) y la acidez titulable (6,54%). Concluimos que las Kcs propuestas en la presente investigación deben evaluarse durante la estación seca porque, en esta investigación, el riego fue inducido por Kc solo durante 2 meses después de las lluvias.

- Abstract
Background: Greater provision of inclusive education is an important goal for education systems internationally. Frequently identified barriers to progress include a lack of resources to support students with special educational needs (SEN) in mainstream education settings. Purpose: This study from Spain sought to gain insight into the availability of educational resources to support students with SEN in mainstream schools in the region of Murcia, by exploring the perceptions of stakeholders. Methods: Participants were 27 stakeholders involved in the development and operation of special classrooms in mainstream settings for students with SEN who require highly specialised attention. Perceptions were gathered from participants across 18 mainstream centres in the region, via semi-structured interviews and focus groups. Data were analysed qualitatively, according to an existing categorisation that distinguished between material, human and teaching space resources. Findings: In-depth analysis suggested that, according to many stakeholders, an insufficiency of educational resources constituted one of the main barriers to achieving inclusive education. Participants believed that material resources in education centres should be increased to support students with SEN, reporting a lack of digital resources and the necessary teacher education for their application in the classroom. Limited availability of human resources was also highlighted, with participants desiring a more substantial presence of professionals in mainstream centres and a deeper commitment towards inclusion. They considered that there should be more space in the centres to conduct multisensory and motivating activities for students with SEN. Conclusions: Catering to the diverse learning needs of all students is a key concern globally. This study underscores the significance of different types of resources in inclusive provision. It draws attention to the importance of increasing the availability of resources in mainstream educational settings to support students with SEN.

We present results of analysis of biological (diatoms and ostracodes) and non-biological (Ti, Ca / Ti, total inorganic carbon, magnetic susceptibility) variables from an 8.8 m long, high-resolution (~ 20 yr sample−1) laminated sediment sequence from Lake Santa María del Oro (SMO), western Mexico. This lake lies at a sensitive location between the dry climates of northern Mexico, under the influence of the North Pacific subtropical high-pressure cell and the moister climates of central Mexico, under the influence of the seasonal migration of the intertropical convergence zone and the North American monsoon (NAM). The sequence covers the last 2000 years and provides evidence of two periods of human impact in the catchment, shown by increases in the diatom Achnanthidium minutissimum. The first from AD 100 to 400 (Early Classic) is related to the shaft and chamber tombs cultural tradition in western Mexico, and the second is related to Post-Classic occupation from AD 1100 to 1300. Both periods correspond to relatively wet conditions. Three dry intervals are identified from increased carbonate and the presence of ostracodes and aerophilous Eolimna minima. The first, from AD 500 to 1000 (most intense during the late Classic, from AD 600 to 800), correlates with the end of the shaft and chamber tradition in western Mexico after ca. AD 600. This late Classic dry period is the most important climatic signal in the Mesoamerican region during the last 2000 years, and has been recorded at several sites from Yucatan to the Pacific coast. In the Yucatan area, this dry interval has been related with the demise of the Maya culture at the end of the Classic (AD 850 to 950). The last two dry events (AD 1400 to 1550 and 1690 to 1770) correspond with the onset of, and the late, Little Ice Age, and follow largely the Spörer and Maunder minima in solar radiation. The first of these intervals (AD 1400 to 1550) shows the most intense signal over western Mexico; however this pattern is different at other sites. Dry/wet intervals in the SMO record are related with lower/higher intensity of the NAM over this region, respectively.

Resumen: Introducción: Se considera que la arteriosclerosis de las arterias extracraneales causa casi un tercio de los ictus isquémicos. El diagnóstico certero del grado de estenosis es fundamental para indicar la mejor estrategia terapéutica. Si bien la angiografía cerebral se considera la técnica de referencia, el estudio ultrasonográfico (EUS) es un procedimiento más disponible, no invasivo y bien establecido en la cuantificación de la estenosis carotídea. Sin embargo, al ser una técnica dependiente del explorador, se recomienda que cada laboratorio valide sus resultados frente a la angiografía. Objetivos: Establecer, en nuestro laboratorio, la validez del estudio neurosonológico en el diagnóstico de la enfermedad ateromatosa extracraneal y determinar su capacidad para cuantificar el grado de estenosis de la arteria carótida interna. Material y métodos: Estudio retrospectivo de los pacientes con enfermedad ateromatosa carotídea extracraneal en cuyo proceso diagnóstico se realizó tanto ultrasonografía carotídea como angiografía por sustracción digital de troncos supraaórticos. Resultados: Se evaluaron 254 carótidas clasificando el grado de estenosis en > 50%, 70-99% y 100%. Para el primer grupo el EUS obtuvo una sensibilidad del 97%, una especificidad del 90%, un valor predictivo positivo (VPP) del 94,6% y un VP negativo (VPN) del 94,2%. En el segundo grupo, se obtuvo: sensibilidad, 96,4%; especificidad, 93%; VPP, 94,4%, y VPN, 95,4%. Para la oclusión carotídea los valores respectivos fueron del 85, el 96,8, el 80 y el 97,8%. Conclusiones: Nuestros datos validan la capacidad del EUS realizado en nuestro laboratorio para el diagnóstico del grado de estenosis carotídea. Abstract: Introduction: Arteriosclerosis of the extra-cranial arteries is believed to be responsible for almost one-third of all ischaemic strokes. The sound diagnosis of the degree of stenosis is essential in deciding the best therapeutic strategy. Although cerebral angiography is considered the reference technique, ultrasound study (UST) is a more readily available, non-invasive and well-established procedure for quantifying carotid stenosis. However, on being a dependent exploratory technique, it is recommended that each laboratory validates its results against angiography. Objetives: To establish the validity of the neuro-ultrasound study in our laboratory for use in the diagnosis of extracranial atheromatous disease, and determine its capacity to quantify the degree of stenosis in the internal carotid artery. Material and methods: A retrospective study of patients with extracranial carotid atheromatous disease, in whom the diagnostic process was carried out with carotid ultrasound as well as supra-aortic trunk digital-subtraction angiography. Results: A total of 254 carotids were evaluated and the degree of stenosis being classified into > 50%, 70-99% and 100%. The UST for the first group had a sensitivity (Se) of 97%, a specificity (Sp) of 90%, a positive predictive value (PPV) of 94.6% and a negative predictive value (NPV) of 94.2%. The second group had an Se of 96.4%, Sp 93%; PPV 94.4% and NPV 95.4%. The respective values for carotid occlusion were, 85%, 96.8%, 80% and 97.8%. Conclusions: Our data validates the ability of UST performed in our Laboratory to diagnose the degree of carotid stenosis.

Introduction: Arteriosclerosis of the extra-cranial arteries is believed to be responsible for almost one-third of all ischaemic strokes. The sound diagnosis of the degree of stenosis is essential in deciding the best therapeutic strategy. Although cerebral angiography is considered the reference technique, ultrasound study (UST) is a more readily available, non-invasive and well-established procedure for quantifying carotid stenosis. However, on being a dependent exploratory technique, it is recommended that each laboratory validates its results against angiography. Objectives: To establish the validity of the neuro-ultrasound study in our laboratory for use in the diagnosis of extracranial atheromatous disease, and determine its capacity to quantify the degree of stenosis in the internal carotid artery. Material and methods: A retrospective study of patients with extracranial carotid atheromatous disease, in whom the diagnostic process was carried out with carotid ultrasound as well as supra-aortic trunk digital-subtraction angiography. Results: A total of 254 carotids were evaluated and the degree of stenosis being classified into >50%, 70–99% and 100%. The UST for the fi rst group had a sensitivity (Se) of 97%, a specificity (Sp) of 90%, a positive predictive value (PPV) of 94.6% and a negative predictive value (NPV) of 94.2%. The second group had a Se of 96.4%, Sp 93%; PPV 94.4% and NPV 95.4%. The respective values for carotid occlusion were, 85%, 96.8%, 80% and 97.8%. Conclusions: Our data validates the ability of UST performed in our Laboratory to diagnose the degree of carotid stenosis. Resumen: Introducción: Se considera que la arteriosclerosis de las arterias extracraneales causa casi un tercio de los ictus isquémicos. El diagnóstico certero del grado de estenosis es fundamental para indicar la mejor estrategia terapéutica. Si bien la angiografía cerebral se considera la técnica de referencia, el estudio ultrasonográfico (EUS) es un procedimiento más disponible, no invasivo y bien establecido en la cuantifi cación de la estenosis carotídea. Sin embargo, al ser una técnica dependiente del explorador, se recomienda que cada laboratorio valide sus resultados frente a la angiografía. Objetivos: Establecer, en nuestro laboratorio, la validez del estudio neurosonológico en el diagnóstico de la enfermedad ateromatosa extracraneal y determinar su capacidad para cuantificar el grado de estenosis de la arteria carótida interna. Material y métodos: Estudio retrospectivo de los pacientes con enfermedad ateromatosa carotídea extracraneal en cuyo proceso diagnóstico se realizó tanto ultrasonografía carotídea como angiografía por sustracción digital de troncos supraaórticos. Resultados: Se evaluaron 254 carótidas clasifi cando el grado de estenosis en > 50%, 70–99% y 100%. Para el primer grupo el EUS obtuvo una sensibilidad del 97%, una especificidad del 90%, un valor predictivo positivo (VPP) del 94,6% y un VP negativo (VPN) del 94,2%. En el segundo grupo, se obtuvo: sensibilidad, 96,4%; especifi cidad, 93%; VPP, 94,4%, y VPN, 95,4%. Para la oclusión carotídea los valores respectivos fueron del 85, el 96,8, el 80 y el 97,8%. Conclusiones: Nuestros datos validan la capacidad del EUS realizado en nuestro laboratorio para el diagnóstico del grado de estenosis carotídea.

Se presentan los resultados de los estudios de paleomagnetismo (primeros 12 metros) y microfósiles (primeros 8 metros) para la secuencia lacustre del lago de Chalco. Estos se han realizado en material recobrado de cuatro perforaciones en el sector central del lago. La reconstrucción paleoambiental propuesta integra los datos de polen, diatomeas, limnología, paleomagnetismo y fechamientos de radiocarbono. La edad estimada para el fondo de la secuencia, a los 12 m, es de 25,000 años antes del presente. Los sedimentos están caracterizados por valores altos de susceptibilidad magnética, los cuales están relacionados a la ocurrencia de material volcánico (se identifican 10 tefras en esta parte de la secuencia). La paleoflora está constituida principalmente por bosques de coníferas y vegetación subacuática. Los datos limnológicos indican fluctuaciones en el nivel del lago, con correspondientes cambios en salinidad y alcalinidad. La disminución o ausencia de paleofósiles en la secuencia correlacionan con la localización de las tefras; ello sugiere una relación con la actividad volcánica. El registro de declinación magnética muestra varias anomalías, de hasta 30 - 60 grados, para aproximadamente los 5,000 años y los 14,000 años. La variación para los 5,000 años ha sido observada también en estudios de rocas volcánicas y podría reflejar una variación del campo geomagnético. El registro de inclinación magnética muestra un patrón más homogéneo, con fluctuaciones alrededor de los 32.9 grados (inclinación dipolar es de 35.3 grados). Sin embargo se tiene también una variación para los 14,000 años, que se resalta en los valores de la anomalía de inclinación. El análisis espectral de los registros de los varios parámetros magnéticos indica varios periodos dominantes. Para la intensidad se tienen del orden de 650 a 2,900 años. Para la declinación se tienen del orden de 850 a 2,900 años. Para la inclinación se tienen del orden de 1,000 a 3,800 años.

Se presentan los resultados de un estudio estratigráfico y de fechamiento radiométrico para los primeros doce metros de la secuencia volcano-sedimentaria del Lago de Chalco, en el sector sureste de la Cuenca de México. Para el estudio se ha analizado el material recuperado de cuatro perforaciones realizadas en la porción central del sector oeste de la cuenca. El modelado de las anomalías de Bouguer indica que la cuenca esta dividida en dos sub-cuencas por un alto estructural N-S que coincide con la estructura volcánica de Xico. El espesor máximo de la secuencia en la parte oeste es de 400 m y en la parte este de 300 m. Este estudio forma parte de un proyecto que incluye análisis del contenido de microfósiles, paleomagnetismo, sedimentología y limnolog1a, encaminado a documentar la evolución paleoambiental y paleoclimática de la Cuenca durante el Pleistoceno tardío y el Holoceno. Cinco unidades mayores pueden ser identificadas en los primeros 12m. intensa actividad volcánica esta representada por 10 horizontes de tefra. El control de edades se ha obtenido a partir de once determinaciones de radiocarbono. La edad a los 9 m de profundidad es alrededor de 19, 000 años. Un cambio marcado en la secuencia ocurre a los 13,000 años, indicado por los fechamientos y la presencia de una tefra y un grueso horizonte de diatomitas. Los cocientes promedio de sedimentación cambian de unos 0.80 mm/año en la parte profunda entre 3.5 y 8.13 m a unos 0.28 mm/año en la parte somera, arriba de los 3.5 m de profundidad. Análisis de las variaciones del contenido de carbón orgánico en la secuencia sugieren que entre 3 y 8 metros corresponden principalmente a un ambiente de lago somero, con acumulación alta de materia orgánica. doi: https://doi.org/10.22201/igeof.00167169p.1994.33.3.1181

Rachael M. Caballero
- Abstract
With an increased focus on teacher retention in the wake of the COVID-19 pandemic there is a need to understand teachers' perceptions about their work. Many special educators cite job design factors related to case management and lack of administrator support as reasons for leaving education. Nevertheless, case management is not widely studied. Case management is the facilitation of special education documents and services. It is completed in addition to typical teacher duties. The dual role of teacher and case manager creates role conflict for special educators. Administrator support can mitigate role conflict experienced by special educators. This study investigated special educators' and administrators' perceptions regarding role conflict in case management and their perceptions regarding principals' support for their role as special education case managers. The study utilized an explanatory sequential mixed methods design. The Role Conflict and Role Ambiguity Scale and the Principal Support Scale were employed to collect quantitative data. 87 high school special educators and 7 high school special education administrators completed the survey. After analysis, the researcher developed interview questions for the qualitative phase. The interview protocol was used with 11 survey respondents to gather explanations of the emerging themes from the quantitative phase. In the analysis, a priori themes included role conflict, role ambiguity, and principal support. Emergent themes included having a dedicated case manager, the legality of special education, administrator job complexity, administrator turnover, teachers supporting teachers, and transition. Teachers indicated perceptions of role conflict and lack of administrator support in the role of case manager. The evidence of these findings provided the following conclusions: (1) The design of special educators' job creates competing priorities between special education process tasks (IEPs, reevaluations, etc.) and instructional tasks (lesson planning, delivering instruction, co-teaching); (2) Special educators need more non-instructional time to complete all the tasks of their job; (3) Teachers value emotional support most, especially support of the special education process; and (4) The complexity of special education administrators' job design impedes their ability to support teachers. These conclusions suggest restructuring the job of special educators' job as a strategy to retain special education teachers.

Des facteurs et des moments critiques influant sur la qualité hygiénique du lait ont été examinés au Costa Rica dans une coopérative de petits éleveurs laitiers qui livraient tous leur lait à une laiterie. Le lait de toutes les vaches en lactation a été examiné avec le CMT (California Mastitis Test). Le lait positif au CMT a subi un examen bactériologique (EB). En outre, des échantillons de lait ont été prélevés dans les cuves de stockage pour le comptage des cellules somatique (CCS) et EB. Huit pour cent des échantillons positifs au CMT ont révélé la présence de S. aureus. Vingt-huit pourcent des échantillons prélevés dans les cuves de stockage contenaient S. aureus et 79 % des échantillons contenaient E. coli. Tous les échantillons pris dans les cuves de stockage de la laiterie avaient un nombre de CFU supérieurà 2.106 cellules/ml. Ce lait était fortement contaminé par des agents bactériologiques provenant de l'environnement. Le refroidissement du lait était inadéquat. La méthode de préparation des mamelles, les appareils de traite insuffisamment aseptisés et l'eau de nettoyage étaient les principales sources de contamination du lait.

Articular cartilage injuries in the knee can lead to post-traumatic osteoarthritis if untreated, causing debilitating problems later in life. Standard surgical treatments fail to ensure long lasting repair of damaged cartilage, often resulting in fibrotic tissue. While there is a vast amount of research into cartilage regeneration, integrating engineered implants with cartilage remains a challenge. As cartilage is a load bearing tissue, it is imperative to evaluate tissue repair strategies and their ability to integrate under mechanical loading. This work established a dynamically loaded ex vivo model of cartilage repair using human cartilage explants. The model was used to assess the efficacy of a stem cell therapy delivered in a bioadhesive hydrogel comprised of photocrosslinkable gelatin methacryloyl (GelMA) and microbial transglutaminase to repair the model defect. Extensive neocartilage production and integration were observed via histology and immunohistochemistry after 28 days chondrogenic culture. Analysis of culture media allowed monitoring of glycosaminoglycan and type II collagen production over time. A mechanical assessment of integration via a push out test showed a 15-fold increase in push out strength over the culture duration. The model was successful in exhibiting robust chondrogenesis with transglutaminase or without, and under both culture conditions. The work also highlights several limitations of ex vivo models and challenges of working with bioreactors that must be overcome to increase their utility. This ex vivo model has the potential to delay the need for costly pre-clinical studies and provide a more nuanced assessment of cartilage repair strategies than is possible in vivo.

Hepatology ,Gastroenterology - Abstract
It has been reported that professional cyclists had an accelerated solid gastric emptying which decreased by increasing the exercise intensity. That could be explained by a predominance of stress-dependent motility inhibitors such gastrointestinal hormones, neurotransmitters and or the predominance of the gastric inhibitory vagal motor circuit. The aim of this preliminary study was to evaluate the role of β-endorphins, inhibitors of gastric motility, in these findings.Gastric emptying of solids marked with TcBasal β-endorphin levels were lower in cyclists vs controls (p0.05) and they increased with the exercise intensity (p0.001). There were no significant differences in gastric emptying of solids with or without naloxone when 75% of the maximum oxygen consumption was reached.The inhibitory effect of the exercise in the gastric emptying of solids does not seem to be secondary to the action of β-endorphins, that leaves the gastric inhibitory vagal motor circuit a more likely predominant role.

The development of electroactive cell-laden hydrogels (bioscaffolds) has gained interest in neural tissue engineering research due to their inherent electrical properties that can induce the regulation of cell behaviour. Hydrogels combined with electrically conducting materials can respond to external applied electric fields, where these stimuli can promote electro-responsive cell growth and proliferation. A successful neural interface for electrical stimulation should present the desired stable electrical properties, such as high conductivity, low impedance, increased charge storage capacity and similar mechanical properties related to a target neural tissue. We report how different electrical stimulation protocols can impact neuronal cells' survival and proliferation when using cell-laden GelMA/GO hydrogels. The rat pheochromocytoma cell line, PC12s encapsulated into hydrogels showed an increased proliferation behaviour with increasing current amplitudes applied. Furthermore, the presence of GO in GelMA hydrogels enhanced the metabolic activity and DNA content of PC12s compared with GelMA alone. Similarly, hydrogels provided survival of encapsulated cells at higher current amplitudes when compared to cells seeded onto ITO flat surfaces, which expressed significant cell death at a current amplitude of 2.50 mA. Our findings provide new rational choices for electroactive hydrogels and electrical stimulation with broad potential applications in neural tissue engineering research.

PEPTIDES ,HYDROGELS ,BRAIN injuries ,DRUG efficacy ,NERVES ,BIOMATERIALS - Abstract
Current therapies for the devastating damage caused by traumatic brain injuries (TBI) are limited. This is in part due to poor drug efficacy to modulate neuroinflammation, angiogenesis and/or promoting neuroprotection and is the combined result of challenges in getting drugs across the blood brain barrier, in a targeted approach. The negative impact of the injured extracellular matrix (ECM) has been identified as a factor in restricting post‐injury plasticity of residual neurons and is shown to reduce the functional integration of grafted cells. Therefore, new strategies are needed to manipulate the extracellular environment at the subacute phase to enhance brain regeneration. In this review, potential strategies are to be discussed for the treatment of TBI by using self‐assembling peptide (SAP) hydrogels, fabricated via the rational design of supramolecular peptide scaffolds, as an artificial ECM which under the appropriate conditions yields a supramolecular hydrogel. Sequence selection of the peptides allows the tuning of these hydrogels' physical and biochemical properties such as charge, hydrophobicity, cell adhesiveness, stiffness, factor presentation, degradation profile and responsiveness to (external) stimuli. This review aims to facilitate the development of more intelligent biomaterials in the future to satisfy the parameters, requirements, and opportunities for the effective treatment of TBI.

Biodegradable polymers have been widely used in tissue engineering with the potential to be replaced by regenerative tissue. While conventional bionic interfaces are designed to be implanted in living tissue and organs permanently, biocompatible and biodegradable electronic materials are now progressing a paradigm shift towards transient and regenerative bionic engineering. For example, biodegradable bioelectronics can monitor physiologies in a body, transiently rehabilitate disease symptoms, and seamlessly form regenerative interfaces from synthetic electronic devices to tissues by reducing inflammatory foreign-body responses. Conventional electronic materials have not readily been considered biodegradable. However, several strategies have been adopted for designing electroactive and biodegradable materials systems: (1) conductive materials blended with biodegradable components, (2) molecularly engineered conjugated polymers with biodegradable moieties, (3) naturally derived conjugated biopolymers, and (4) aqueously dissolvable metals with encapsulating layers. In this review, we endeavor to present the technical bridges from electrically active and biodegradable material systems to edible and biodegradable electronics as well as transient bioelectronics with pre-clinical bio-instrumental applications, including biodegradable sensors, neural and tissue engineering, and intelligent drug delivery systems.

The cluster R136 in the giant star-forming region 30 Doradus in the Large Magellanic Cloud (LMC) offers a unique opportunity to resolve a stellar population in a starburst-like environment. We obtain the near-infrared to ultraviolet extinction towards 50 stars in the core of R136, employing the `extinction without standards' method. To assure good fits over the full wavelength range, we combine and modify existing extinction laws. We detect a strong spatial gradient in the extinction properties across the core of R136, coinciding with a gradient in density of cold gas that is part of a molecular cloud lying northeast of the cluster. In line with previous measurements of R136 and the 30 Doradus region, we obtain a high total-to-relative extinction ($R_V = 4.38 \pm 0.87$). However, the high values of $R_V$ are accompanied by relatively strong extinction in the ultraviolet, contrary to what is observed for Galactic sightlines. The relatively strong ultraviolet extinction suggests that the properties of the dust towards R136 differ from those in the Milky Way. For $R_{V} \sim 4.4$, about three times fewer ultraviolet photons can escape from the ambient dust environment relative to the canonical Galactic value of $R_{V} \sim 3.1$ at the same $A_{V}$. Therefore, if dust in the R136 star-bursting environment is characteristic for cosmologically distant star-bursting regions, the escape fraction of ultraviolet photons from such regions is overestimated by a factor of three relative to the standard Milky Way assumption for the total-to-selective extinction. Furthermore, a comparison with average curves tailored to other regions of the LMC shows that large differences in ultraviolet extinction exist within this galaxy. Further investigation is required in order to decipher whether or not there is a relation between $R_V$ and ultraviolet extinction in the LMC., Accepted for publication in A&A (18 pages, 12 figures)

General Medicine - Abstract
The gastric mucosa has been studied since the pre-Helicobacter pylori (H. pylori) era, but the complete descriptions of the stomach and duodenum have been anecdotal, and those of the distal duodenum, exceptional. Our aim was to evaluate the different epidemiologic characteristics and the gastroduodenal inflammatory status in patients with upper gastrointestinal symptoms.We studied 138 patients divided into: the non-ulcer group (functional dyspepsia [n = 77] and GERD [n = 27]) and the ulcer group (peptic ulcer [n = 13] and duodenal ulcer [n = 21]). Ten biopsy samples (2 from the corpus, 3 from the antrum, 3 from the proximal duodenum, and 2 from the distal duodenum) were taken in each patient for histologic and/or microbiologic study.The prevalence of dyspepsia, functional dyspepsia, and H. pylori was 80.4%, 69.4%, and 82.6%, respectively. The frequency of superficial chronic gastritis in the corpus was significantly higher in the ulcer group vs. the non-ulcer group, whereas there was more chronic atrophic gastritis in the antrum in the ulcer group (P0.05). Duodenitis was significantly more frequent in the ulcer group vs. the non-ulcer group, in both the proximal and distal duodenum. Pangastroduodenitis was a significant finding in the ulcer group. In both groups, chronic gastritis (corpus and antrum) and duodenitis (proximal and distal) were significantly related to the presence of H. pylori. Proximal duodenitis is not an uncommon finding in functional dyspepsia (37.7%) and is twice as frequent as distal duodenitis (16.9%).The ulcer group presented with a gastroduodenal inflammatory map different from that of the non-ulcer group and was characterized by a higher frequency of superficial chronic gastritis in the corpus, chronic atrophic gastritis in the antrum, and a very high frequency of proximal duodenitis.
