Quantification of leghaemoglobin content in pea nodules based on near infrared hyperspectral imaging spectroscopy
and chemometrics
Authors: Eylenbosch Damien , Dumont Benjamin , Baeten Vincent , Bodson Bernard , Delaplace Pierre , Pierna Juan
Published: June 2018

Leghaemoglobin content in nodules is closely related to the amount of nitrogen fixed by the legume–rhizobium
symbiosis. It is, therefore, commonly measured in order to assess the effect of growth-promoting parameters such as
fertilisation on the symbiotic nitrogen fixation efficiency of legumes. The cyanmethaemoglobin method is a reference
method in leghaemoglobin content quantification, but this method is time-consuming, requires accurate and careful
technical operations and uses cyanide, a toxic reagent. As a quicker, simpler and non-destructive alternative, a method
based on near infrared (NIR) hyperspectral imaging was tested to quantify leghaemoglobin in dried nodules. Two
approaches were evaluated: (i) the partial least squares (PLS) approach was applied to the full spectrum acquired with
the hyperspectral device and (ii) the potential of multispectral imaging was also tested through the preselection of the most
relevant wavelengths and the building of a multiple linear regression model. The PLS approach was tested on mean
spectra acquired from samples containing several nodules and acquired separately from individual nodules. Peas (Pisum
sativum L.) were cultivated in a greenhouse. The nodules were harvested on four different dates in order to obtain
variations in leghaemoglobin content. The leghaemoglobin content measured with the cyanmethaemoglobin method in fresh
nodules ranged between 1.4 and 4.2 mg leghaemoglobin g–1 fresh nodule. A PLS regression model was calibrated on
leghaemoglobin content measured with the reference method and mean NIR spectra of dried nodules acquired with a
hyperspectral imaging device. On a validation dataset, the PLS model predicted the leghaemoglobin content in nodule
samples well (R2 = 0.90, root mean square error of prediction = 0.26). The multispectral approach showed similar
performance. Applied to individual nodules, the PLS model highlighted a wide variability of leghaemoglobin content in
nodules harvested from the same plant. These results show that NIR hyperspectral imaging could be used as a rapid and
safe method to quantify leghaemoglobin in pea nodules.

A New Heuristic Formulation for a Competitive Maximal Covering Location Problem
Authors: Seyhan Tolga H. , Snyder Lawrence V. , Zhang Ying
Published: June 2018

We consider a competitive facility location problem in which two firms engage in a leader–follower game. Both firms would like to maximize the customer demand that they capture. Given the other player’s decision, each player’s problem is the classical maximal covering location problem. That is, the leader has to solve a bi-level problem in which the second-level problem is NP-hard. To overcome this, we use the greedy add algorithm as an approximation for the follower’s response and formulate a mixed-integer programming model that embeds the follower’s heuristic response into the leader’s constraints and solve it as a single-level problem. The resulting formulation is tractable and provides near-optimal solutions for the leader’s decision. We analyze the performance of the heuristic both theoretically and computationally. We also provide alternate formulations for the same problem and compare them.
FLIRT E ATOPIA: O CONTO-ENSAIO
Authors: Pereira Paulo Alexandre
Published: June 2018

No presente artigo, depois de expender algumas reflexões em torno da natureza transicional e atópica da forma ensaística, discute-se o modo como, em instâncias recorrentes de confluência intergenérica, no conto encontra acolhimento a pulsão indagativa e filosofante que constitui o proprium do ensaio. Com efeito, apesar do muito que, nos planos retórico e conceptual, parece separá-los, conto e ensaio partilham entre si afinidades histórico-genéticas e traços processuais que as três narrativas breves selecionadas para análise – de Fernando Pessoa, Jorge de Sena e Gonçalo M. Tavares – não deixam de evidenciar. Nesse sentido, argumenta-se que, nestas ficções breves, em que a efabulação se compagina com a deriva abstrata ou especulativa, a retórica ensaística reveste insistente tonalidade autorrefleviva, convertendo o conto-ensaio num ensaio sobre o conto.
Study Design and qPCR Data Analysis Guidelines for Reliable Circulating miRNA Biomarker Experiments: A Review
Authors: de Ronde Maurice W J , Ruijter Jan M , Moerland Perry D , Creemers Esther E , Pinto-Sietsma Sara-Joan
Published: June 2018

BACKGROUND

In the past decade, the search for circulating microRNA (miRNA) biomarkers has yielded numerous associations between miRNAs and different types of disease. However, many of these relations could not be replicated in subsequent studies under similar experimental conditions. Although this lack of replicability may be explained by the variation in experimental design and analysis methods, guidelines on the most appropriate design and analysis methods to study circulating miRNAs are scarce.

CONTENT

miRNA biomarker experiments generally consist of a discovery phase and a validation phase. In the discovery phase, typically hundreds of miRNAs are measured in parallel to identify candidate biomarkers. Because of the costs of such high-throughput experiments, the number of individuals included in those studies is often too small, which can easily lead to false positives and false negatives. In the validation phase, a small number of identified biomarker candidates are measured in a large cohort of cases and controls, generally by quantitative PCR (qPCR). Although qPCR is a sensitive method to measure miRNAs in the circulation, experimental design and qPCR data analysis remain challenging. Omitting some crucial steps in the design and analysis of the qPCR experiment or performing them incorrectly can cause serious biases, ultimately leading to false conclusions.

In this review, we aim to expose and discuss the most common sources of interstudy variation in miRNA research from a methodological point of view and to provide guidelines on how to perform these steps correctly to increase replicability of studies on circulating miRNAs.

Curating Context: The Art Institute of Chicago’s 1945 Leopoldo Méndez Exhibition
Authors: Merfish Beth Matusoff
Published: June 2018

This article considers the exhibition of the work of leftist Mexican printmaker Leopoldo Méndez at the Art Institute of Chicago in 1945. Showing Méndez’s work in a manner that illuminated the artist’s communist loyalties could have been controversial in the postwar milieu, but the exhibition did not generate negative publicity. The professionals of the Art Institute, most notably Katherine Kuh and Carl Schniewind, perpetuated the invented populist legacy of printmaker José Guadalupe Posada to provide a folkloric and regional context for the work of Méndez. They thereby provided a reading that encouraged audiences to overlook the contemporary leftist political importance of Méndez’s work, and made the prints palatable to an audience that might otherwise have reacted strongly to the work of a communist Mexican artist at a time when the Good Neighbor Policy had come to an end and the Cold War had begun. This case study, the dynamics of which were repeated at parallel exhibitions at the Brooklyn Museum of Art, exemplifies the crucial challenge of the curatorial representations that have not problematized the context of the artistic narratives that they present.
Exhibiting the End: Curatorial Scenarios of Burial, Contagion and Extinction
Authors: Connolly Maeve
Published: June 2018

This article examines curatorial strategies used to contextualize, dramatize and narrativize events that unfold over timescales far exceeding that of the individual human lifespan, sometimes involving life forms that are posthuman or other-than-human. Three exhibition projects from 2015 will be analysed – A Breathcrystal curated by Mihnea Mircan, Riddle of the Burial Grounds curated by Tessa Giblin, and Disappearing Acts curated by Matt Packer and Arne Skaug Olsen – each of which explores situations of actual or potential disaster resulting from exposure to nonhuman organisms, nuclear waste or rising seas caused by climate change. Informed by T. J. Demos and Fredric Jameson’s theorizations of ‘negative utopianism’ in art theory and science fiction, I explore how these curatorial scenarios investigate the properties of human and nonhuman entities, whether encountered in the present or from vantage points of the distant past or future.
‘Savoy Truffle’: Love, lust and longing in a box of chocolates
Authors: Neill Lindsay , Hemmington Nigel
Published: June 2018

This article re-reads The Beatles’ song, ‘Savoy Truffle’, not as an ode to Eric Clapton’s rotting teeth and chocolate consumption, but rather as a thinly veiled rock music metaphor reflecting the triptych love relationship between its composer, George Harrison, his wife, Pattie Boyd, and her lover and later husband, Eric Clapton. Re-reading ‘Savoy Truffle’ provides a valuable insight into the intricacies of how popular rock music communicates constructs of love within metaphor and how The Beatles integrated multiple meanings into lyrics conveying love and its contention. Such multiplicity aids explanations exploring the band’s extraordinary popularity by providing a socio-temporal insight into an extra-ordinary time: the 1960s. In re-reading ‘Savoy Truffle’, this article contextualizes the multiplicity of love itself within an exploration of the passion within lust, the longing of desire and the satisfaction of having the desired object. The desired object was Pattie Boyd, who Harrison projected within a box of ‘Good News’ chocolates.
Fatores Simbólicos e Instrumentais de Atração de Pessoas em PMES Relações com o Estilo de Liderança do Empreendedor
Authors: Reis Germano Glufke , Fernandes Bruno Rocha , Nakata Lina Eiko
Published: June 2018

A gestão de pessoas em pequenas e médias empresas (PMEs) tem sido pouco abordada pela literatura que, em geral, foca as grandes empresas. Esta pesquisa busca preencher essa lacuna, investigando a relação entre o estilo do empreendedor e as abordagens de atração de pessoas em PMEs. Para tanto, foi realizado um survey com 146 PMEs, testando um conjunto de hipóteses por meio de modelagem de equações estruturais. Os resultados indicam haver uma relação entre o estilo do empreendedor (transformacional versus transacional) e os tipos de atributos (simbólicos ou instrumentais) enfatizados na atração de pessoas. Também foi observado que quanto maior a empresa, menor ênfase é dada a fatores simbólicos. Já PMEs comerciais/varejo enfatizam mais fatores simbólicos de atração do que outros segmentos. Por outro lado, os resultados indicam que as abordagens de atração são mais impactadas pelo estilo do empreendedor em si, do que por características da empresa/negócio (idade, tamanho, segmento).

Pollution is one of the important issues faced by marine resources including zooxanthellae, which is known to be very sensitive to environmental changes. Some pollutants have been reported to have adverse effects on zooxanthellae, however, their sensitivity in regards to changes on cell size of these algae has not been widely explored. This study examined the effects of pollutants on the sensitivity of zooxanthellae through changes in size. Zooxanthellae were isolated from corals Porites lutea, Acropora aspera, and Montipora digitata collected from Panjang Island, Jepara, Indonesia. These algae were exposed to pollutants i.e. heavy metals (Cu, Cd, Pb) and nutrients (ammonium and phosphate) at concentrations of 5,10,15 ppb and 5,10,15 μM, respectively. Zooxanthellae size were measured five hours after pollutants exposure. The results showed that all treatments reduced the size of zooxanthellae. Algae isolated from P. lutea are the least affected by pollutants and the highest percentage cell size reduction was found in phosphate treatment. However, reduction on the size of algae were not statistically significant. These results indicate that in relation to reduction in the size, zooxanthellae are not sensitive to pollutants. Keywords: Zooxanthellae, pollutants, sensitivity, size reduction
Nowe widzenie – astrologiczny i astronomiczny wymiar wizji fotograficznej
Authors: Łuczak Dorota
Published: June 2018

The paper focuses on the New Vision – one of the most important developments in the history of the twentieth-century photography, whose ambition was to modernize human perception, hence also society. A project with such an objective, characteristic of the avant-garde, required not only the use of photography as a tool of “ocularcentrism,” to use a term coined by Martin Jay, but also some more solid epistemological and ontological foundation. The author analyzes the project of the New Vision, introducing two interpretive contexts, i.e. astrology and astronomy, which are understood as specific paradigms of cognition and knowledge. First, both concepts are located in a more general discourse of the philosophy of history (Nietzsche, Benjamin), and second, they are related to the practice and theory of the New Vision and the idea of developing a new vision of reality, shown at the famous “Film und Foto” exhibition (Stuttgart, 1929). The basis of the present interpretation is methodological reflection on the ideologization of photography in the so-called revisionist studies which favor the critique of the apparatus of power. Instead, the author proposes a concept of photographic vision connecting the picture and the spectator or, in other words, calling for taking into consideration the process of reception. This proposal, close to Hans Belting’s anthropology of the image, renounces the idea of the passive spectator, subject to the picture, in favor of the analysis of its perception. In the context of the New Vision, the picture-spectator relationship has been approached in terms of astrology and astronomy.
Pamięć autobiograficzna w czasach cyfryzacji
Authors: Michałowska Marianna
Published: June 2018

The analysis of everyday practices focused on photography has always been an important element of the theoretical reflection on the media. Such a social approach can be found in the writings of classics, such as Benjamin, Sontag, Barthes, and Berger, as well as contemporary theorists. In their works one can find reflection on the cultural need to create one’s image both for oneself and for others. In theory, this problem has been formulated in different ways. It may refer to making a family album (Hirsch) or to the selfie as an “extension and enhancement of a long tradition of the self-portrait” (Mirzeoff) or to action that embodies an imagined identity, rooted in communication practices (van Dijck). The gist of those discussions is the perception of oneself and others, and the technological methods of picturing, experiencing, and distributing that perception in society. The paper presents an analysis of the evolution of cultural meanings attributed to the autobiographical memory that affects the concept of identity. Photobiographies can be placed between two extremes: the nineteenth-century belief that “photography cannot flatter,” remembered by Douve Draaisma, and contemporary picture-editing programs. José van Dijck argues that contemporary digital pictures are usually “living” since they can be endlessly modified. The paper has been divided into two parts. One is a short survey of qualitative methods, based on photography and the idea of the autobiographical memory. The other presents biographical artistic practices of Krzysztof Pruszkowski, Nancy Burson, Marek Lalko, and Josef Klammer, as well as autobiographical Internet production (e.g., selfie and time-lapse photography). The conclusion is that the digital media have changed the status of the autobiographical memory by mediatizing its presence in reality.
Agreement in grammar and discourse: A research overview
Authors: Haig Geoffrey , Forker Diana
Published: June 2018

Agreement is among the most widely-researched issues in theoretical linguistics. In this introduction, we critically review some of the key issues, focussing on typological approaches to agreement, the role of agreement in establishing and maintaining reference, and the emergence of agreement diachronically. We point to the interplay of semantic, pragmatic and syntactic factors in shaping the way agreement systems function, and emphasize the need for more usage-based research in understanding the impact of extra-syntactic factors. We also argue for greater attention to lesser-researched languages, particularly those where features other than person are central in agreement relations. Finally, we offer a short synopsis of the contributions to this issue.

Validity of the handheld Doppler to determine lower-limb blood flow restriction pressure for exercise protocols. J Strength Cond Res 34(9): 2693–2696, 2020—Handheld (HH) Doppler is frequently used for determining the arterial occlusion pressure during blood flow restriction exercises; however, it is unknown whether the blood flow is occluded when the auscultatory signal is no longer present. The purpose of this study was to assess the validity between the HH Doppler and the Doppler ultrasound (US) measurements for determining the arterial occlusion pressure in healthy men. Thirty-five participants underwent 2 arterial occlusion pressure measurements. In the first measure, a pressure cuff (17.5 cm wide) was placed at the most proximal region of the thigh and the pulse of posterior tibial artery was detected using an HH Doppler probe. The cuff was inflated until the auscultatory pulse was no longer detected. After 10 minutes of rest, the procedure was repeated with the Doppler US probe placed on the superficial femoral artery. The cuff was inflated up to the point at which the femoral arterial blood flow was interrupted. The point at which the auscultatory pulse and blood flow were no longer detected was deemed the arterial occlusion pressure. There were no significant differences in arterial occlusion pressure level between the HH Doppler and the Doppler US (133 [±18] vs. 135 [±17] mm Hg, p = 0.168). There was a significant correlation (r = 0.938, p = 0.168), reasonable agreement, and a total error of the estimate of 6.0 mm Hg between measurements. Arterial occlusion pressure level determined by the HH Doppler and the Doppler US was similar, providing evidence that the HH Doppler is a valid and practical method.
Influence of Sex on Current Methods of Adjusting Saddle Height in Indoor Cycling

Encarnación-Martínez, A, Ferrer-Roca, V, and García-López, J. Influence of sex on current methods of adjusting saddle height in indoor cycling. J Strength Cond Res 35(2): 519–526, 2021—The popularity of indoor cycling has increased in fitness centers, and therefore, proper bike fitting is important to avoid biomechanical-related injuries. However, no previous studies have compared the biomechanical kinematics of various existing protocols of saddle-height adjustment in indoor cycling. Furthermore, it was not clear if these protocols were appropriate for both men and women, as these equations were primarily obtained in male cyclists. Therefore, lower-limb joint kinematics were compared among 4 different protocols of saddle-height adjustment (1-Preferred, 2-Ferrer-Roca et al., 3-Lemond & Guimard, and 4-Static Goniometry) in 30 experienced indoor-cycling subjects (15 men and 15 women). Only 20–33% of the women had a knee extension while pedaling within the recommended range for each of the different protocols except for the preferred adjustment (73% were within). By contrast, all the protocols were moderately suitable for men (47–60% were within the recommended range). A multiple linear equation to estimate the recommended saddle height in both men and women (R
2 = 0.917, p = 0.001) was obtained from the following variables: inseam length, stature, foot length, and knee angle. The differences in the findings between men and women may be partially explained by differences in anatomical structures, as well as the male-based equations, which argues the need for future investigations in female cyclists.

Published: June 2018

Introducción. El síndrome de Bouveret es una entidad poco frecuente de íleo biliar que provoca obstrucción gástrica debido a la presencia de un lito biliar a nivel de píloro o duodeno y secundaria a una fistula biliodigestiva. Esta enfermedad es de difícil diagnóstico y una de sus complicaciones es la hemorragia digestiva alta; su manejo es quirúrgico y se recomienda en dos tiempos, aunque se puede manejar por endoscopia alta en aquellos cálculos <2.5cm. El pronóstico es bueno, con un post-operatorio sin novedades.Presentación del caso. Paciente de 63 años con cuadro clínico de 15 días de evolución de dolor en epigástrico y vómitos biliosos incontables. Se realizaron imágenes diagnósticas donde se evidenció masa calcificada en duodeno II, por lo que la paciente fue intervenida quirúrgicamente: se progresó el cálculo a yeyuno, se realizó enterotomía y se extrajo el lito. Al quinto día fue dada de alta sin novedades.Conclusión. El síndrome de Bouveret es una entidad rara que requiere de una adecuada valoración médica y de métodos auxiliares de imágenes para un diagnóstico oportuno.

El sujeto y la ética en Michel Foucault
Authors: Hernández Castro Gustavo
Published: June 2018

El presente artículo tiene como objetivo analizar el pensamiento de Michel Foucault en torno al sujeto y la ética y su vínculo con la modernidad. Para establecer esa relación se analiza las categorías focultianas de saber, poder y gobernabilidad.  El saber y el  poder se organizan para someter la conducta de los sujetos; mientras la gobernabilidad debe ser analizada en dos vías; desde las prácticas de subjetivación, es decir, como un espacio en el cual se deben descubrir las significaciones originarias y en la cual se funda el sujeto; y por la desubjetivación mediante el cual, el sujeto ya no es el mismo, se desprende de sí,  para convertirse en otro sujeto.
Aceleracionismo y arte contemporáneo
Authors: Harillo Pla Adrià
Published: June 2018

En el presente artículo se presenta el concepto de Aceleracionismo, aunque no se realizará un análisis profundo del término. La principal aportación de este texto pretende ser, por el contrario, la aplicación del movimiento aceleracionista al caso del arte contemporáneo. Si bien este intento de unión ya aporta un valor académico por sí mismo, la hipótesis concreta sobre la que se trabaja y que será aquí desarrollada es que, debido a las particularidades institucionales del arte contemporáneo, el Aceleracionismo no es un mecanismo válido para su superación y cambio de paradigma, si es que un cambio de esta naturaleza fuese necesaria.
A theory of economic cycles
Authors: Dobos Imre , Ábel István
Published: June 2018

The theory of economic motion was András Bródy’s main interest. This paper presents a simplifi ed framework of Bródy’s economics. His multi-sector production and price theory is based on the Marxian theory of value reinterpreted by using measurement considerations. Economic motion in this framework is driven by technology represented by the internal proportions of production, not by external shocks. Prices and proportions jointly determine the economic structure and its motion (duality of prices and volumes). We derive the laws of motion of production and use of goods (consumption and accumulation) based on technological accounting balances. These laws determine a cyclical pattern. Using numerical examples we demonstrate how external changes in technology and valuations are propagated in changing the cyclical pattern of motion.
Market and democracy: Friends or foes? Theories reconsidered
Authors: Gedeon Péter
Published: June 2018

The paper examines theories on the relationship of market and democracy. Four theorems may be distinguished: (1) The necessity theorem: market (M) is the necessary condition of democracy (D) ([M→D]+). (2) The inequality theorem: market undermines democracy ([M→D]–). (3) The optimality theorem: democracy is the optimal condition of market ([D→M]+). (4) The disability theorem: democracy undermines the market ([D→M]–). My question is whether these theorems include or exclude each other. After the reconstruction of the four theorems I examine the six possible combinations of them. My conclusion is that the theory stating that market and democracy mutually reinforce each other is compatible with the theory discussing the confl icts between market and democracy: the two theories do not constitute a logical contradiction. This analysis assists in understanding why the relationship of capitalism and democracy may be relatively stable: the selectivity of democracy and the political restrictions of market do not undermine, do not eliminate economic and political freedom, but sustain it in a modifi ed form.
Zorunlu-Kitlesel Göç Olgusuna Sosyolojik Bir Yaklaşım: Türkiye’deki Suriyeli Sığınmacılar Örneği

Göç; ister bireysel ve gönüllü olsun, ister kitlesel ve
zorunlu olsun birçok sorunu beraberinde getiren bir süreçtir. Göç basit bir
mekân değişikliği değil, göç edenin zihninde başlayıp mekân değiştirme ile
devam eden bir sosyal olgudur. Sosyal ve kültürel çevreyi değiştirir ve göçmeni
yeni bir ilişkiler ağına sokar. Göç, sağlıktan eğitime, barınmadan istihdama,
ekonomiden örgütlenmeye bir dizi uyum, değişim ve dönüşüm gerektiren süreçtir.

Son yıllarda Suriye’den Türkiye’ye doğru gerçekleşen zorunlu
ve kitlesel göç; hem göç eden Suriyelileri, hem de göçü kabul eden Türk
vatandaşlarını olağanüstü göç koşulları ile yüzleşmek zorunda bırakmıştır.
Ancak bu yakın geçmişte yaşanmış en büyük göç hareketi, hareketin büyüklüğüne
oranla minimum düzeyde sorunlarla yürütülmektedir. Bunu sağlayan faktörler iki
toplumun ortak tarih, inanç ve kültürel değerlere sahip olması, akrabalık ve etnik
aidiyet ilişkileri, bütün bunların ötesinde devlet desteği ve sivil toplum
katkılarıdır. Bu kitlesel ve ani
göçün ilk beş yılında Türkiye’de hükümet yetkililerinden yerel yönetimlere,
bürokrasiden tüm sivil toplum kuruluşlarına kadar herkes bir yardım
seferberliğine girişmiştir. Yapılan bu yardım ve dayanışmanın temel dinamiğini
ensar-muhacir kardeşliği söylemi oluşturmuştur. Türkiye adeta ensar–muhacir
kardeşliğinin modern zamanlarda yeniden üretilebileceğini kanıtlamıştır. Daha
sonraki yıllarda ise bu göç, daha rasyonel bir biçimde ekonmik ve sosyal gerçeklere
göre şekillenmeye başlamıştır.

Bu çalışmada Suriye’den Türkiye’ye doğru yaşanan kitlesel ve
zorunlu göç; sorunlar, çözümler, uyum ve toplumsal bütünleşme açısından ele
alınmıştır.

Published: June 2018

Abstract The mineral nutrition is essential to increase yield and fruit quality of passion fruit. There is no information of nutrient accumulation throughout the production cycle. Thus, in order to assist in the correct nutrients supply and update the recommendations, studies involving cultivars and cultivation techniques are necessary. The aim of this study was to evaluate the plant growth, the nutrient accumulation and the exportation in plants of yellow passion fruit cv. IAC 275. The experimental design was a randomized block, with three replications, where the treatments were evaluation times. Stem length, dry mass matter and nutrient accumulation in aerial part (leaves and stems), fruits and roots were evaluated. The maximum daily accumulation rate and periods of maximum nutritional requirement were calculated, in addition to the nutrient extraction and exportation. The nutrient accumulation at the end of the cycle, at 450 days after sowing, were in g plant-1: N (178.5) > K (162.4) > Ca (70.8) > Mg (14.8) > S (13.3) > P (11.0) and mg plant-1: Fe (827.6) > Mn (130.7) > Zn (69.8) > B (56.7) > Cu (17.8).

Abstract Studies on adaptation to the cultivation site are necessary for the recommendation of new cultivars. The aim of this study was to evaluate the phenological development, productivity and fruit quality of eight blueberry cultivars from the rabbiteye group (Aliceblue, Bluebelle, Bluegem, Briteblue, Climax, Delite, Powderblue and Woodard) and two from the highbush group (Georgiagem and O’Neal) under humid subtropical conditions in the 2012/2013, 2013/2014 and 2014/2015 cycles. Beginning and end of flowering, beginning and end of harvesting, fruit set, production, mass, diameter, pH, content of soluble solids, titratable acidity, ratio and coloring were evaluated. The evaluated cultivars presented flowering in the period from July to September, concentrating harvest in the months of November and December. The highest fruit set was observed in Delite, Climax, Briteblue and Powderblue cultivars. There were differences among cultivars regarding fruit mass, size, pH, content of soluble solids and acidity. The results showed that the cultivars exhibited blue color with few variations over the evaluation years. Cultivars with the best productive performance under humid subtropical climate conditions are Bluegem, Delite, Climax and Powderblue.

ABSTRACT Objective: To evaluate the profile of patients with osteoporotic fractures treated at a tertiary orthopedic hospital. Methods: Using questionnaires, 70 patients with osteoporotic fractures (OF) were compared with 50 outpatients with multiple osteoarthritis (OA) followed through an outpatient clinic. Results: The OF group was older (p <0.001), less heavy (p=0.003), had lower BMI (p=0.006), was more likely to be white (p=0.011), was less likely to be married (p=0.008), and had previous falls, previous fractures, old fractures (>1 year), falls in the last 12 months, fractures due to falls, and needed more assistance (p<0.05). They also had lower Lawton & Brody Instrumental Activities of Daily Living scores (p <0.05) and reported less lower limb disability, foot pathology, muscle weakness, hypothyroidism, and vitamin D intake than patients in the OA group. White race, previous falls, and previous fractures increase the risk of osteoporotic fractures by 10.5, 11.4, and 4.1 times, respectively. The chance of fracture dropped 29% for each one-unit increase in Lawton & Brody IADL score. Married participants had fewer fractures than participants with other marital status. Conclusion: Together, race, marital status, previous falls, foot pathologies, previous fractures, and IADL scores define the profile of patients with osteoporotic fractures.

ABSTRACT Objective: To collect data from patients with cervical fracture who were treated surgically in a tertiary health service, in order to better understand the current scenario of this kind of injury in our population. Methods: This retrospective survey examined consecutive cases of patients with cervical spine trauma who received surgical treatment during 2013 and 2014. The data were subjected to descriptive statistical analysis. Results: Fifty-two patients were treated with surgery during 2013 and 2014. All patients classified as Frankel A and B developed respiratory failure. Patients classified as Frankel A, B, and C had significantly higher rates for postoperative complications (p < 0.01) than patients classified as Frankel D and E, except for the rate of postoperative infections (p = 0.717). Hospitalization time was also longer in the first group (p < 0.01). Conclusion: Patients with cervical trauma who present with neurological deficit at hospital admission should receive special attention, since the rate of postoperative complications is higher and hospital stays are lengthier in this group. In addition, patients with Frankel A and B classification should be monitored in an intensive care unit. Level of Evidence III; Retrospective comparative study.

ABSTRACT Objective: It is difficult to define parameters for management and factors associated with primary bone lymphoma (PBL). This article presents the experience in a single institution with 42 patients with PBL over a 16-year period (2000-2016). Methods: Fifty-five patients were retrospectively evaluated, and forty-two were included (76.3%). Results: Median age at diagnosis was 51.5 years, and median follow-up was 102.7 months. One patient had HIV. Pain in the affected site was the most prevalent symptom. The average time between symptom onset and diagnosis was 5.4 months. The vertebrae were most affected (n=16, 33.3%). According to the International Prognostic Index Score (IPI), 64.3% of the patients were classified as having low-grade lymphoma and 25.7% as low-intermediate. The most common histology was diffuse large B cell lymphoma (DLBCL) (85.7%). Immunophenotyping was CD20 positive in 93.5% of patients, and 11 patients had pathological fracture. All patients received chemotherapy and 30% of the regimens included rituximab. Thirty-eight percent of patients received radiation therapy. Overall survival was 50%, and survival median time was 80 months. Age and chemotherapy regimen influenced patient survival. Younger patients and patients who received RCHOP had better prognoses. Conclusions: The choice of chemotherapy regimen associated with age influenced survival for patients with PBL. Level of Evidence IV; Case series.

ABSTRACT Objective: To conduct a systematic review of literature about the use of contralateral patellar tendon autograft in anterior cruciate ligament reconstructions and present the results. Methods: The LILACS, MEDLINE, Cochrane, PubMed, Scielo and Google Scholar databases were searched without date restrictions for the keywords “anterior cruciate ligament reconstruction” combined with “contralateral” in the article title. After the studies were identified, two independent evaluators collected the qualitative characteristics of the studies and classified them according to clinical outcomes of these grafts as positive, neutral, or negative. Results: A total of 755 articles were found initially, and after detailed evaluation of all references, followed by a screening process and assessment of quality, a total of 11 studies were determined to be eligible for inclusion in this systematic review. Of these, 72.72% were level II studies, the most common level of evidence among the results. Positive results for this type of graft were found in 63.63% of the studies. Conclusion: Based on the literature review, most of the included articles (63.63%) presented positive results for the use of contralateral patellar tendon grafts.

ABSTRACT Objective: Globally, more than 1.2 million people die from traffic accidents each year. In order to reduce the rate of traffic accidents and their subsequent social consequences in Sao Paulo, Brazil, the aim of this study was to characterize pedestrian victims of traffic accidents and occurrences. Methods: This is a cross-sectional, quantitative, descriptive and retrospective epidemiological study of 2723 pedestrians injured in traffic accidents during 2016 in Sao Paulo. Results: Of the total sample, 37.3% participants were female and 62.7% male; incidence was highest in the 10-19 year old age group (19.9%) and lower limb injuries were most frequent (28.6%). Of the cases attended in urgent health care units, 75.6% progressed to hospital discharge. Accidents were more frequent in the afternoon (44.6%), and most commonly involved cars (47.2%). Conclusions: This study showed the importance of making detailed records of traffic accidents to guide the government in intensive education efforts to develop a healthy society and respect for traffic regulations, to promote urban improvements involving signage and pavement, and to maintain pre-hospital and hospital care teams in strategic locations to minimize the time elapsed between the accident and care provided to the victim.

ABSTRACT Objective: The purpose of this study was to reproduce a mouse model of bone sarcomas for use in cancer research. Methods: A fresh sample of the tumor tissue was implanted subcutaneously into nude mice. When the patient-derived xenograft (PDX) reached a volume of 1500 mm3, it was harvested for re-implantation into additional mice. Histology was used to compare the morphological characteristics of different generations of sarcoma xenografts with the primary tumor. Results: Sixteen sarcoma tissue samples were engrafted into nude mice. Nine patients were diagnosed with osteosarcoma, two with chondrosarcoma, two with malignant peripheral nerve sheath tumor, one with synovial sarcoma, one with pleomorphic sarcoma, and one with Ewing’s sarcoma. PDX tumors were generated in 11 of the 16 implanted specimens (69% success rate in P1). Six P1 tumors grew sufficiently for transfer into additional mice, producing the P2 generation, and three P2 tumors established the P3 generation. Conclusion: PDX tumors generated from bone sarcomas were successfully established in immunodeficient mice and reproduced the characteristics of the primary tumor with a high degree of fidelity. The preclinical PDX model described herein may represent an important tool for translational oncology research and for evaluating therapeutic strategies for bone sarcomas.

ABSTRACT Objective: To analyze 10 consecutive cases of microsurgical arteriovenous loops created to reconstruct complex injuries from March 2011 to May 2012. Methods: This observational cohort-type study conducted by the Hand and Microsurgery Group at the HC-FMUSP included patients who were candidates for microsurgical reconstruction as a last alternative to amputation of the limb with proven absence of adequate recipient vessels for primary microsurgical anastomosis, in a prospective and consecutive manner. We analyzed 14 variables (epidemiological, clinical, procedure-related, and outcome) in patients who underwent reconstruction using an arteriovenous loop utilizing a single-stage or two-stage procedure. Results: The injuries were mostly traumatic (80%). The success rate of the single-stage procedure was 75%, and 17% for the two-stage procedure. The rate of preservation for the injured limb was 44%. Conclusion: This study reinforces the more recent understanding that the indication for single-stage or two-stage reconstruction should be individualized; our findings favor the single-stage reconstruction. This technique should be used in selected cases, as a last reconstructive alternative before amputation, and further studies are necessary to confirm its safety and efficacy in our practice. Level of Evidence IV; Case series.
