Authors: Dorvillé Luís Fernando Marques , Selles Sandra Lúcia Escovedo
Published: July 2016

Ao longo das últimas décadas, um número crescente de comunidades evangélicas e adventistas tem defendido o criacionismo em nosso país. Este artigo se propõe a examinar as matrizes identitárias desse movimento, suas transformações ao longo do tempo e a influência de seus discursos na sociedade, em particular no ensino de ciências e biologia. Sugere-se que o enfrentamento dessa situação deva envolver práticas que contribuam para uma melhor compreensão da atividade científica, enfatizando a relevância da sua abordagem na formação inicial. É destacada ainda a importância de atividades didáticas capazes de promover um ambiente de respeito pelas diferentes visões de mundo ao mesmo tempo em que trabalham o conhecimento transmitido pela ótica do estranhamento, desabilitando zonas de conforto.
Floral traits as potential indicators of pollination vs. theft
Authors: Souza Camila Silveira de , Aoki Camila , Ribas Augusto , Pott Arnildo , Sigrist Maria Rosângela
Published: July 2016

Abstract Floral visitation does not necessarily mean pollination, as several animals utilize floral resources without transferring pollen. Since pollinators and thieves can affect the reproduction, morphology and diversification of flowering plants, we here investigated if attributes of flowers and flowering of plant species collected in the central Brazilian vereda would predict the pollination (pollen seeking) or theft (pollen/nectar theft) during the visits. It was hypothesized that non specialized flowers would have a higher incidence of thievery, where as specialization, for example, the presence of large and medium flowers with long corolla, making it difficult to access nectar, would lead to increased pollination. As a result, four attributes were mainly associated with illegitimate visits, and in order of importance, they are size (small), quantity of flowers per plant (large), flowering time (< 10 months) and floral type (inconspicuous). The richest and most abundant visitor groups, including bees, flies and wasps, acted mainly as potential pollinators, while cockroaches, butterflies, beetles, ants and hemipterans acted as thieves. However, further studies are required to confirm that this pattern is repeated in other larger and more diverse communities, thus confirming the possible preference for floral thieves.

Medical training and nurses of Family Health strategy on worker health aspect
Authors: Mori Érika Chediak , Naghettini Alessandra Vitorino
Published: July 2016

Considering the worker’s health one of the Unified Health System (SUS) tasks, the Primary Health Care (PHC) and the Family Health Strategy (FHS) play an important role in the development of health actions in the field health-work. In Brazil, where the number of informal and domiciled jobs is high, the FHS becomes a reference in the workers’ health actions. Therefore, if the FHS is not attentive to the relation between professional occupation and disease, several diseases that affect workers can overload the system without obtaining a cure. The aim of this study is to evaluate doctors and nurses recognition of the Family Health Strategy on occupational diseases in Aparecida de Goiânia. This is a qualitative descriptive study and the data analysis was done by content analysis. The setting for this study contemplates FHS units in the municipality of Aparecida de Goiânia, Goiás. There were 8 Basic Health Units and 16 health professionals were interviewed. The data was collected in the participants of the interview workplaces, from February through April, 2013, after being approved by the Ethics and Research Committee. The discourses were analyzed according to Minayo (2007), using thematic analysis. The interviews were recorded and later transcribed for analysis. Among the 16 professionals interviewed we observed that only 3 (18.75%) received professional training on occupational health in their Institution, however the aim of the courses were towards situations of biological hazards and not about workers care. Practitioners reported lack of knowledge in the occupational health area, and also observed that the area is still undervalued and underexplored in the academic and professional fields, and even by the Municipality health management. Evaluating the academic education it is possible to observe the inadequacy of the subject workload, where professionals reported the lack of knowledge in the area and the low workload of the subject in the academic field. Conclusion: There is a need to raise awareness and interest of the municipality health managers and the health professionals, doctors and nurses, towards the relations work-health-disease and the need to capacitate these professionals, in order to assist the workers in a better way.

Published: July 2016

ABSTRACT OBJECTIVE To describe the constitution and operation of a voluntary interruption of pregnancy team of a university hospital, from the outlook of the mental health team. METHODS In this case study, the following aspects were analyzed: 1) historical background; 2) implementation of Law 18,897 of October 22, 2012; and 3) functioning of the program at the Hospital de Clínicas of the Facultad de Medicina (Universidad de la República, Uruguay), taking into account three dimensions: structure, process, and results. RESULTS Between December 2012 and November 2013, a total of 6,676 voluntary interruptions of pregnancy were reported in Uruguay; out of these, 80 were conducted at the Hospital de Clínicas. The patients’ demographic data agreed with those reported at the national level: Of the total patients, 81.0% were aged over 19 years; 6.2% decided to continue with the pregnancy; and only 70.0% attended the subsequent control and received advice on contraception. CONCLUSIONS In its implementation year in Uruguay, we can assess the experience as positive from the point of view of women’s health. Our experience as a mental health team at the Hospital de Clínicas, inserted into the multidisciplinary voluntary interruption of pregnancy team, is in the process of assessment and reformulation of practices.

Authors: Oliveira Albertina L , Silva José T , Lima Margarida P
Published: July 2016

ABSTRACT OBJECTIVE To validate the Escala de Autoeficácia para a Autodireção na Saúde (EAAS – Self-efficacy for Self-direction in Health Scale). METHODS Non-experimental quantitative study of EAAS validation, by confirmatory factorial analyses, evaluating a sample of 508 older adults from the north and the center of Portugal with mean age of 71.67 (from 51 to 96 years), to whom the Self-efficacy for Self-direction in Health Scale, the Rosenberg Self-esteem Scale, the Positive and Negative Affect Schedule, the Satisfaction with Life Scale, and the Instrumental Activities of Daily Living Scale were applied. The EAAS was developed from the theoretical constructs of self-efficacy and from self-directed learning within the PALADIN European project framework, aiming to develop an instrument able to assess the extent to which older adults take good care of their health. RESULTS The internal consistency was 0.87 (Cronbach’s alpha) and confirmatory factorial analyses enabled to find a model near the one theoretically proposed, indicating a structure consisting of four dimensions: physical exercise, healthy diet, engaging in health-related learning, and visits to health professionals. From the psychometric point of view, the model in four factors showed quite satisfactory fit indicators. CONCLUSIONS The Self-efficacy for Self-direction in Health Scale, with 16 items, is adequate to evaluate to what extent older adults have confidence in their ability to take care of their own health, with high degree of autonomy.
Influence of Nitrogen Status on the Sensitivity of Glyphosate-Resistant and -Susceptible Tall Waterhemp (Amaranthus tuberculatus) and Palmer Amaranth (Amaranthus palmeri)
Authors: Kohrt Jonathon R. , Young Julie M. , Matthews Joseph L. , Young Bryan G.
Published: June 2016

Anecdotal observations of improved glyphosate efficacy on glyphosate-resistant (GR) tall waterhemp populations in corn production compared with soybean suggested the presence of nitrogen (N) fertilizer may influence the expression of glyphosate resistance. Greenhouse and field experiments were conducted to determine the influence of soil-applied nitrogen fertilizer on the growth rate and sensitivity of glyphosate-susceptible (GS) and GR tall waterhemp and Palmer amaranth. The addition of supplemental fertilizer increased the relative growth rate (plant height and shoot volume), number of nodes, and percentage of shoot nodes with axillary branches on GS and GR biotypes of both weed species. The axillary bud activity was increased 52 and 8% with increasing N for the GR and GS biotypes of tall waterhemp and Palmer amaranth, respectively. The GS populations of tall waterhemp and Palmer amaranth were more sensitive to glyphosate in the greenhouse under increased fertilizer levels compared with no fertilizer. Additionally, GR tall waterhemp was more sensitive to glyphosate under the higher fertilizer treatments, which resulted in a reduction in the calculated resistance factor (RF) from 27.8 under no fertilizer to 4.7 for the high fertilizer treatment. The RF for GR Palmer amaranth was not influenced by the fertilizer treatments in the greenhouse. Field experiments demonstrated that glyphosate efficacy may be greater on GR populations of tall waterhemp and Palmer amaranth under high N conditions, but these results were not consistent and most likely were influenced by soil moisture in 2012, which was more limiting than N supply. This research implies that soil fertility can influence the sensitivity of some GR weed species to glyphosate and the RF. Therefore, the evolution and management of GR weed species in commercial crop production may be influenced by the nutrient status of the soil and the use of supplemental fertilizers.

Ethics and theories of communication: power, interactions, and participative culture
Authors: Martino Luis Mauro Sá , Marques Ângela Cristina Salgueiro
Published: July 2016

The aim of this paper is to make an epistemological approach of the ethical conceptions presented in the main Communication Theories, identifying in some of its epistemological proposals elements of an ethos. It is highlighted how these theories approach communicative mediated processes and at the same time propose procedures and practical actions. We develop our argument in a historical-critical perspective, mapping how notions of power, communicative capacities and constitution of the political citizen, among others are interlaced to the theoretical articulations of the research field. The analysis is developed around three perspectives: (a) antisymmetrical, evincing the way power is placed side by side with media; (b) symmetrical, making equivalent, in different spaces, media producers and receivers; (c) paritarian, with intersections between these two types of agents in a participative culture. The text analyzes these three perspectives focusing the ruptures and continuities between ethics and epistemology.

Published: June 2016

La cuenca de drenaje del Rio Lozoya (Comunidad de Madrid) es una depresión tectónica ubicada en la parte oriental del Sistema Central Español. Esta área está caracterizada por una litología muy heterogénea y una historia estructural muy compleja. Durante el Cuaternario, en este sector, se generó una extensa secuencia de terrazas rocosas que demuestra la enrevesada evolución de relieve en la cuenca del Río Lozoya. La ausencia de depósitos sedimentarios hace muy difícil  obtener información numérica a partir de este tipo de morfologías. Para poder superar esta problemática se ha empleado el método de datación por exposición de una superficie erosiva por isotopos cosmogénicos mediante una modelización inversa de chi-cuadrado para ajustar los valores medidos de 10Be y 26Al en modelos de perfiles de profundidad en dos niveles de la secuencia regional de terrazas rocosas: TE15 (+62-64m) y TE17 (+42-46m). En ambos casos, los ratios de concentración 26Al/10Be en las muestras medidas es muy parecido al ratio de producción superficial (~6,75), lo que indica una constante exposición. Usando la modelización inversa, se han calculado edades mínimas de>232 ka y ratios de erosión 18-19 mm/ka para TE15 y >140 ka y 7-8 mm/ka para TE17.
Modelado fractal de la distribución del tamaño de dolinas en el macizo kárstico de la Sierra de las Nieves (Málaga, España)
Authors: Pardo Iguzquiza Eulogio , Durán Valsero Juan José , Robledo Ardila Pedro Agustín
Published: June 2016

El estudio de la distribución espacial de dolinas en terrenos kársticos puede proporcionar una información muy valiosa acerca de la geomorfología e hidrogeología del macizo kárstico, además de posibles controles tectónicos. En este trabajo se ha analizado la distribución espacial de dolinas en el macizo kárstico de la Sierra de las Nieves en la provincia de Málaga (España). Es este un karst mediterráneo de relieve alto, caracterizado por una elevada precipitación y que forma un importante acuífero kárstico donde las dolinas actúan de colectores de recarga concentrada y muestran un marcado control estructural, habiéndose desarrollado a lo largo de las direcciones preferentes de fracturación. Las dolinas aparecen en grupos, pudiéndose distinguir tres grupos principales relacionados con el funcionamiento hidrogeológico del macizo; aunque, atendiendo al control tectónico, se pueden diferenciar dos familias de dolinas en función de su localización geográfica. La distribución estadística de los tamaños de todo el conjunto de dolinas sigue una ley potencial que indica un comportamiento fractal y se ha especulado con los motivos para tal comportamiento. Asimismo se propone el vuelo de Lévy como modelo estocástico para la distribución espacial y tamaño de las depresiones. Esta información puede ser de gran utilidad para mejorar el conocimiento geomorfológico y de evolución del macizo kárstico.
La deglaciación de las áreas libres de hielo de las islas Shetland del Sur (Antártida). Ejemplos de Byers (Livingston) y Barton (King George)

Published: June 2016

El proceso de deglaciación de las actuales áreas libres de hielo existentes en la zona de la Antártica marítima tiene notables repercusiones geomorfológicas y ecológicas. No obstante, la cronología del retroceso glaciar es aún poco conocida. Éste es el caso de las áreas deglaciadas existentes en las penínsulas Byers (isla Livingston) y Barton (isla King George). La datación de la base de los sedimentos recolectados en diferentes lagos emplazados en estas dos penínsulas permite inferir la edad de aparición de cada lago que, integrando el conjunto de dataciones, posibilita la reconstrucción del patrón espacial y temporal de la deglaciación de estos espacios. Las técnicas empleadas para el establecimiento de la cronología de los sedimentos de los lagos se han basado en el uso complementario de dataciones de radiocarbono y termoluminiscencia. En ambas penínsulas la aparición de superficies libres de hielo se inició durante el Holoceno superior, en torno a los 8 ka cal BP. Las áreas más alejadas de los casquetes glaciales actuales y las zonas más elevadas de ambas penínsulas (nunataks) fueron las primeras superficies en quedar expuestas. Durante el Holoceno medio (entre 5-6 ka cal BP) el sector central de estas áreas fue progresivamente deglaciado. Durante el Holoceno superior los frentes glaciares permanecen circunscritos a la posición que determinan las morrenas frontales actuales, con avances y retrocesos menores.

Análisis del film Tomboy
Authors: Truzzoli Claudia
Published: June 2016

Una película de Céline Sciamma, que nos conduce a reflexionar acerca de la configuración de la identidad sexual en la que nos inscribimos todos de una u otra manera. Tema que ha sido objeto de controversia en lo que se refiere a las causas que determinan dicha identidad. Los que se inclinan por las explicaciones antropológicas son más proclives a considerarla un resultado de la cultura en la que se inscribe un sujeto. Los amantes de la determinación genética, más esencialistas, se decantan por un determinismo biológico algunos, otros por un determinismo estructural que corresponde al psiquismo. Todas estas explicaciones causales dejan un vacío frustrante cuando pretenden explicar la identidad apelando sólo por una única causa. A mí me interesa un enfoque multidisciplinar que integre además la concepción de la diferencia de género en el análisis de esta cuestión.

Las nuevas tecnologías como herramienta para la igualdad de género: Mujeres inmigrantes religiosas del barrio del Raval, Barcelona
Authors: Sabaté Gauxachs Alba
Published: June 2016

En el barrio del Raval (Barcelona) viven más de 10.000 mujeres inmigrantes. Traen consigo tradiciones y religiones que se incorporan al variopinto abanico que convive en la citada zona de la ciudad. En este estudio hemos investigado el papel de las nuevas tecnologías en el entorno de las mujeres inmigrantes de distintas religiones y países. Nuestro objetivo es saber si estas herramientas suponen un elemento para la igualdad de género y la integración. Para ello hemos realizado 238 entrevistas que nos han permitido obtener datos significativos. Tras las conversaciones, nos damos cuenta de que existe un elevado acceso a las tecnologías pero que a pesar de su potencial integrador, el uso que le dan se limita a su entorno más próximo y, en cualquier caso, potencia más la relación con el país de origen y el pasado que la integración con el nuevo contexto y el presente.
El valor de la palabra en la prevención de la violencia de género en contextos escolares
Authors: López-García-Torres Rocío , Saneleuterio Elia
Published: June 2016

Los planes de prevención de la violencia en la escuela deben contemplar que esta no solo se manifiesta de manera física, sino también verbal. El lenguaje es, además, el germen del problema, especialmente en los casos de violencia de género, y en esencia aglutina parte de su solución. Reconocemos el papel fundamental de la educación en su atención y vigilancia como premisa para alcanzar la igualdad entre mujeres y hombres. Precisamente con nuestra propuesta, basada en el estudio de programas anti acoso y de prevención de conductas sexistas, consideramos diez pautas de comunicación verbal eficaces para la prevención de la violencia de género y el fomento de la igualdad, dirigidas al profesorado, que deberían asumir las políticas educativas e instituciones escolares.

Authors: Zelenikhin P.V. , Makeeva A.V. , Nguen T.N. , Siraj Y.A. , Ilinskaya O.N.
Published: June 2016

Some microbial ribonucleases (RNases) demonstrate selective cytotoxic effect against a wide range of tumor cells. In this context combined use of cytotoxic RNases in complex therapy with other chemotherapeutic agents appears to be especially promising. In this study we have investigated the apoptosis-induced effect of Bacillus pumilus RNase (binase) in combination with known anti-tumor antibiotic bleomycin on human lung adenocarcinoma A549 cells. The combined effect of high concentrations of these agents did not have any mutual increase in their apoptosis-induced action, while a combination of non-apoptotic concentrations resulted in the increase of the proportion of apoptotic cells up to 22% as compared with individual effect of bleomycin (6%) and binase (12%) used separately. These results indicate that binase and bleomycin are effective in combination of their low concentrations and ineffective in combination of their high concentrations.

Tissue specific expression of genes encoding cholesterol transporters ABCA1 and ABCG1 as well as genes encoding the most important transcriptional regulators of adipogenesis – LXRa, LXRb, PPARg and RORa has been investigated in intraabdominal adipose tissue (IAT) samples.A direct correlation between the content of ABCA1 and ABCG1 proteins with RORa protein level (r=0.480, p<0.05; r=0.435, p<0.05, respectively) suggests the role of the transcription factor RORa in the regulation of IAT ABCA1 and ABCG1 protein levels. ABCA1 and ABCG1 gene expression positively correlated with obesity indicators such as body mass index (BMI) (r=0.522, p=0.004; r=0.594, p=0.001, respectively) and waist circumference (r=0.403, p=0.033; r=0.474, p=0.013, respectively). The development of obesity is associated with decreased IAT levels of RORa and LXRb mRNA (p=0.016 and p=0.002, respectively). These data suggest that the nuclear factor RORa can play a significant role in the regulation of cholesterol metabolism and control IAT expression of ABCA1 and ABCG1, while the level of IAT LXRb gene expression may be an important factor associated with the development of obesity.

Previously it found that the bienzymatic conjugate superoxide dismutase-chondroitin sulfate, catalase (SOD-CHS-CAT) increased the survival rate of rats with endotoxic shock caused by the administration of lipopolysaccharide (LPS). This effect was observed both in preventive (before LPS) and therapeutic conjugate administration (after the administration of LPS). This study shows that the development of endotoxic shock is accompanied by increased levels of NO in the liver, lungs, kidneys, heart; administration of the SOD-CHS-CAT conjugate insignificantly influenced this parameter. At the same time, the changes in blood urea and creatinine suggest the protective effect of the conjugate on renal function, while diverse changes in biochemical parameters studied complicate the formation of the agreed conclusions on the state of other organs.

It is known that disorders in the cell functioning of the organs/tissues is accompanied by increased expression of certain receptors. A modern approach to improve the specificity of the drug accumulation in the affected area is to construct the delivery nanosystems with the address fragments. Active tagged transport may help to reduce the dose of the drug, minimizing the impact on healthy cells and organs (reduced adverse events). This approach is particularly important in oncology because of the high toxicity of the drugs used. In this work we have obtained and characterized the pharmaceutical composition of doxorubicin and chlorine e6 into colloidal nanoparticles with synthesized previously targeted conjugates based on folic acid and biotin. On the cell culture Hep G2 it was shown an increase in the internalization of drugs when they were introduced in the incubation medium in the form of drug compositions with transport nanosystems and targeted fragments.

Са2+ is a very important and versatile intracellular signal which controls numerous biochemical and physiological (pathophysiological) processes in the cell. Good evidence exists that mitochondria are sensors, decoders and regulators of calcium signaling. Precise regulation of calcium signaling in the cell involves numerous molecular targets, which induce and decode changes of Са2+ concentrations in the cell (pumps, channels, Са2+-binding proteins, Са2+-dependent enzymes, localized in the cytoplasm and organelles). Mitochondrial Са2+ uniporter accumulates excess of Са2+ in mitochondria, while Na+/Са2+- and H+/Са2+-antiporters extrude Са2+ in the cytoplasm. Mitochondrial Са2+ overloading results in formation of mitochondria permeability transition pores which play an important role in cell death under many pathological conditions. Mitochondria regulate Са2+ homeostasis and control important cellular functions such as metabolism, proliferation, survival. Identification of cellular and mitochondrial Ca2+ transporters and understanding their functional mechanisms open up new prospects for their using as therapeutic targets

Published: June 2016

La Ley Orgánica de Educación Superior de Ecuador, establece que todas las Universidades deben contar con un sistema de seguimiento a sus graduados. A partir de este planteamiento, el presente estudio pretende determinar la situación actual de los graduados de la Carrera de Economía en relación al empleo, formación, y satisfacción laboral y la relación con su formación. Para ello, se ha revisado y analizado la base de datos de la Universidad Nacional de Chimborazo, y por otra parte, se aplicó una encuesta a la población involucrada. Los resultados muestran que cerca a la media, considera suficiente la formación obtenida en la Carrera y en un porcentaje similar, se encuentran muy satisfechos respecto a su empleo actual. La satisfacción laboral de los graduados tiene relación al apoyo recibido en el proceso de titulación y la formación recibida, éste último contrastado a través de una hipótesis que refleja una relación medianamente significativa. No obstante, existen otros factores externos que influyen en la satisfacción laboral del graduado.

ABSTRACT

 

The Organic Law on Higher Education of Ecuador establishes that all universities should have a system of monitoring to its graduates. From this approach, the present study aims to determine the current situation of graduates of the School of Economics in relation to employment, training and job satisfaction and the relationship with their training. To this end, the database of the National University of Chimborazo has been reviewed and analyzed and, on the other hand, a survey of the population involved was applied. The results show that close to the average, considered sufficient training obtained in their career and a similar percentage is found to be very satisfied about their current employment. Job satisfaction of graduates has support in relation to the process of qualifications and training received, the latter contrasted through a hypothesis reflects a fairly significant relationship. However, there are other external factors that influence the graduate job satisfaction.

 Keywords. Monitoring to graduates, training, satisfaction, employment.

SUMMARY

 

This research aims to assess advance and progress of food security policies and strategies implemented in Ecuador for the last ten years. For this, literature about progress and achievements of State implemented policies and programs - related to food security - has been reviewed. It is evident the effort made by the Government in the search of guaranteeing food availability and access to the population. Still, though, there is the need to establish guidelines for fostering concrete and systematic actions; also, development players and agents’ participation in the implementation of programs and projects needs to be enhanced and coordinated; thus, guarantee outcomes, sustainability, and life quality betterment of the Ecuadorian population.

 

Key words: food security, advance and progress, policies and strategies, Ecuadorian population. 

 
MOBILITY AND DISCOURSE CIRCULATION IN THE CONTEMPORARY WORLD: THE TURN OF THE REFERENTIAL SCREW
Authors: Fabrício Branca Falabella
Published: June 2016

In this paper I call into question the referential paradigm, drawing on the conceptual framework developed by contemporary Anthropology, Linguistic Anthropology, Sociolinguistics and Applied Linguistics. I call for the urgent problematization of the so-called referential metaphysics while arguing that constructs such as entextualization and indexicality can shake the strong representational tradition in the field of language studies – a tradition sustained by an infectious modernist linguistic ideology and authoritarian and monist models of reality. The latter have been losing ground, as an explanatory apparatus, amidst the intense mobility and complexity of globalization processes which require new theoretical-analytical tools.  This work is licensed under a Creative Commons Attribution 3.0 License.
LEGITIMACY, AUTHORITY AND MOBILITY IN A MULTI-SCALAR UNIVERSITY CLASS MEDIATED BY WEB TECHNOLOGIES

The aim of this article is to identify and describe the interactional flow dynamics between participants of a course developed using web technology mediation by a consortium of graduate programs in different Brazilian states in the first half of 2015. Based on the analysis of multimedia records on the development of the course, three interaction spaces, or locales, are identified and described between the participants of the course (Skype, live-and-in-person learning classes and Wikispaces), understood as heterogeneous spaces, but interwoven through technological mediation. Based on the affordances and constraints of the technologies used, as well as multi-scale topography observed in these spaces, the interactional flow at and through each level is not linear, as it is governed by legitimacy and authority parameters that not only refer to the conventional school participation modes, but also point to more complex ones.  This work is licensed under a Creative Commons Attribution 3.0 License.
Cancer control in resource-limited settings

Cervical cancer is one of the leading causes of death for women globally. In the Pacific, it is the most common cancer among adult women. Yet it is almost completely preventable, if precancerous lesions are identified and treated early in a timely manner.  This is the biggest challenge for Pacific island countries – to establish a practical and affordable comprehensive cancer control programme that is accessible by all women to improve cancer prevention and care.

The diagnosis, prognosis, and management of patients with gliomas are largely dictated by the pathological analysis of tissue biopsied from a selected region within the lesion. However, the heterogeneous and infiltrative nature of gliomas make it difficult to identify the optimal region for biopsy with conventional magnetic resonance imaging (MRI). This is particularly true for low-grade gliomas, which are often nonenhancing tumors. To improve the management of patients with such tumors, neuro-oncology requires an imaging modality that can specifically identify a tumor's most anaplastic/aggressive region(s) for biopsy targeting. The addition of metabolic mapping using spectroscopic MRI (sMRI) to supplement conventional MRI could improve biopsy targeting and, ultimately, diagnostic accuracy. Here, we describe a pipeline for the integration of state-of-the-art, high-resolution, whole-brain 3-dimensional sMRI maps into a stereotactic neuronavigation system for guiding biopsies in gliomas with nonenhancing components. We also outline a machine-learning method for automated histological analysis that generates normalized, quantitative metrics describing tumor infiltration in immunohistochemically stained tissue specimens. As a proof of concept, we describe the combination of these 2 techniques in a small cohort of patients with grade 3 glioma. With this work, we aim to present a systematic pipeline to stimulate histopathological image validation of advanced MRI techniques, such as sMRI.

2-hydroxyglutarate (2-HG) has emerged as a biomarker of tumor cell isocitrate dehydrogenase mutations that may enable the differential diagnosis of patients with glioma. At 3 T, detection of 2-HG with magnetic resonance spectroscopy is challenging because of metabolite signal overlap and spectral pattern modulation by slice selection and chemical shift displacement. Using density matrix simulations and phantom experiments, an optimized semi-LASER scheme (echo time = 110 milliseconds) considerably improves localization of the 2-HG spin system compared with that of an existing point-resolved spectroscopy sequence. This results in a visible 2-HG peak in the in vivo spectra at 1.9 ppm in the majority of isocitrate dehydrogenase-mutated tumors. Detected concentrations of 2-HG were similar using both sequences, although the use of semi-LASER generated narrower confidence intervals. Signal overlap with glutamate and glutamine, as measured by pairwise fitting correlation, was reduced. Lactate was readily detectable across patients with glioma using the method presented here (mean Cramér–Rao lower bound: 10% ± 2%). Together with more robust 2-HG detection, long-echo time semi-LASER offers the potential to investigate tumor metabolism and stratify patients in vivo at 3 T.
Optoacoustic Tomography Using Accelerated Sparse Recovery and Coherence Factor Weighting

Published: June 2016

Sparse recovery algorithms have shown great potential to accurately reconstruct images using limited-view optoacoustic (photoacoustic) tomography data sets, but these are computationally expensive. In this paper, we propose an improvement of the fast converging Split Augmented Lagrangian Shrinkage Algorithm method based on least square QR inversion for improving the reconstruction speed. We further show image fidelity improvement when using a coherence factor to weight the reconstruction result. Phantom and in vivo measurements show that the accelerated Split Augmented Lagrangian Shrinkage Algorithm method with coherence factor weighting offers images with reduced artifacts and provides faster convergence compared with existing sparse recovery algorithms.
