Secondary and Micronutrient Uptake, Partitioning, and Removal across a Wide Range of Soybean Seed Yield Levels
Authors: Gaspar Adam P. , Laboski Carrie A.M. , Naeve Seth L. , Conley Shawn P.
Published: June 2018

Micronutrient uptake was strongly influenced by environment and/or variety.

Leaf tissue micronutrient concentrations varied largely between growth stages and within each specific growth stage.

Total micronutrient uptake for soybean yield of 6,700 kg ha−1 was <0.9 kg ha−1 for Zn, Mn, Cu, Fe, and B.

Late season S supply is critical as sulfur uptake during seed fill increased with yield, while remobilization from vegetative tissue was relatively less than that of N.

Reduced atmospheric S deposition, in conjunction with higher grain sale prices and steadily increasing yields of soybean [Glycine max (L.) Merr.], has many growers considering an increase in secondary and micronutrient applications. Limited information exists quantifying requirements of S, Mg, Ca, Zn, Mn, Cu, Fe, and B across a wide yield range for modern soybean production systems. Using six site‐years and eight varieties, plants were sampled at six growth stages and partitioned into their respective plant parts and analyzed. Nutrients were acquired heavily (48–73%) from R1 through R5.5 with peak uptake rates near R3. Yet, uptake after R5.5 represented a greater portion of total S uptake as yield increased from the low (24.9%) to high (32.2%) yield level (3608 vs. 5483 kg ha−1). This coincided with seed S accumulation, which relied more heavily on continued uptake after R5.5 (58%) vs. vegetative S remobilization (42%). Across all environments (site × year) and varieties, total S uptake (0.004 kg S kg grain−1) and removal (0.003 kg S kg grain−1) showed moderate (R2 = 0.58) and strong (R2 = 0.76) relations with yield, respectively. These relations for each micronutrient were much weaker (R2 = 0.13–0.66), due largely to the main effects of environment and variety along with their respective interactions with yield. Furthermore, micronutrient concentrations in leaf tissue varied considerably (CV = 28–46%) during recommend testing stages. Thus, previously reported inconsistent yield responses to foliar application of these micronutrients may primarily be due to the large variability in leaf tissue concentrations and nutrient requirements.
Ammonia Emissions from Subalpine Forest and Mountain Grassland Soils in Rocky Mountain National Park
Authors: Stratton Joshua J. , Ham Jay , Borch Thomas
Published: June 2018

Atmospheric deposition of NH3 and NH4+ contributes to eutrophication within sensitive subalpine ecosystems of Rocky Mountain National Park (RMNP) in the United States. However, little is known about the local contribution of NH3 from soils within the park. Thus, the goal of this study was to quantify and compare NH3 emissions from intact soil cores sampled from a subalpine grassland and forest within RMNP. Cores were collected at 2‐wk intervals from 20 June 2011 to 12 Sept. 2011 and transferred to a laboratory chamber system for NH3 flux measurements. Additionally, N wet deposition was monitored at the sampling location to investigate possible impacts on NH3 soil emissions. The average quantifiable NH3 emissions (with SDs) from intact soil cores analyzed in the laboratory (23°C) were 0.42 ± 0.30 mg NH3–N m−2 d−1 for grassland soil and 0.21 ± 0.03 mg NH3–N m−2 d−1 for forest soil (p < 0.001). A mechanistic model was developed to estimate the impact of temperature on soil emissions using the chamber data and field‐site air temperatures. Average estimated NH3 emissions from the field site over the study period were 0.21 and 0.082 mg NH3–N m−2 d−1 for grasslands and forests, respectively. Ammonium wet deposition was not correlated to short term reemission of NH3 based on N isotope analysis. This work provides new information on the magnitude of NH3 emissions from native subalpine soils, indicating that natural emissions are not likely major sources of NH3 in the RMNP airshed.

Core Ideas

We assessed NH3 emissions from native subalpine soils in the RMNP.

NH3 emissions from grassland and forest soils within RMNP were directly compared.

NH3 emissions from forest soils were significantly lower than grassland soils.

Natural NH3 emission from soils likely plays a minor role in NH4+ wet deposition in the RMNP.
The Effect of Water Deficit and Waterlogging on the Yield Components of Cotton
Authors: Wu Hao , Wang Xiugui , Xu Min , Zhang Jinxing
Published: June 2018

The objectives of this study were to determine the influence of waterlogging alone, drought alone, and alternating drought and waterlogging on cotton (Gossypium hirsutum L.) yield and yield components. Water deficit and waterlogging experiments were conducted at the flowering and boll‐setting stages of cotton. The lint and cottonseed yields were reduced after waterlogging alone, drought alone, and alternating drought and waterlogging. The lint and cottonseed yields under alternating drought and waterlogging were greater than those under drought alone. When alternating drought and waterlogging, the drought stage decreased the lint and cottonseed yields, whereas the waterlogging stage had a compensatory effect. The decrease in the number of opening bolls might be the major reason for the observed decrease in lint and cottonseed yields. Waterlogging alone, drought alone, and alternating drought and waterlogging all led to an increase in the proportion of the boll wall biomass and a decrease in the proportion of the fiber biomass of cotton bolls. The proportion of the seed biomass of cotton bolls always decreased, except under alternating drought and heavy waterlogging in 2015. The fiber/seed biomass ratio decreased, except under drought alone in 2015. These findings might provide data to support the prevention of cotton yield loss under drought and waterlogging.
Assessment of ecotoxicological effects of ciprofloxacin in Daphnia magna: life-history traits, biochemical and genotoxic effects
Authors: Nunes B. , Leal C. , Rodrigues S. , Antunes S. C.
Published: June 2018

Antibiotics (e.g. ciprofloxacin) have been detected in surface water and groundwater for several decades. In order to understand the potential impact of the continuous exposure of aquatic organisms to ciprofloxacin, a chronic assay was carried out with Daphnia magna. This approach allowed evaluation of the effects of ciprofloxacin on life-history and sub-individual parameters (antioxidant status and metabolic response: activities of catalase and glutathione S-transferases – GSTs; peroxidative damage; thiobarbituric acid reactive substances and genotoxic effects (genetic damage index, measured by the comet assay). Life-history parameters of D. magna showed no significant effects after ciprofloxacin exposure. Concerning oxidative stress and metabolism parameters, no significant alterations were reported for catalase and GSTs activities. However, a dual response was observed, with a significant decrease in lipid peroxidation levels at low ciprofloxacin concentrations (<0.013 mg/L), while a significant increase was verified at high ciprofloxacin concentrations (0.078 mg/L). The genotoxicity assay detected a significant increase in genetic damage index up to 0.013 mg/L of ciprofloxacin. The here-tested ciprofloxacin concentrations, which are ecologically relevant, did not cause significant impacts concerning the life-history parameters of D. magna; however, at the same levels of ciprofloxacin an oxidative stress and genotoxic damage scenarios were recorded.

Published: June 2018

Al analizar el estudio de la durabilidad en las restauraciones dentales, la clorhexidina aparece como un agente antibacteriano de amplio espectro, con capacidad de inhibir la actividad proteolítica de algunas enzimas que pueden degradar las fibras colágenas de la capa híbrida y de aumentar la capacidad de adhesión en una restauración. Este artículo analiza los aspectos generales en las soluciones de clorhexidina a dos concentraciones diferentes, observando los beneficios o desventajas que presentan sobre el barrillo dentinario y la posibilidad de que una restauración tenga mejor fijación sobre la dentina. Para la obtención del material, se realizó una búsqueda basada en la literatura, utilizando como fuente las bases de datos PubMed y Scielo. Se emplearon los descriptores de búsqueda: “clorhexidine”, “dentine”, “solutions”, y se relacionaron con los términos: “cavity preparations”, “desadaptaciones”, “recurrence decay”. Los resultados de la presente revisión evidencian que las sustancias de clorhexidina en el campo odontológico son de gran utilidad e importancia porque proporcionan múltiples resultados cuando son aplicadas en procesos de restauración y tejidos adyacentes a la misma. Al aplicar el 2% de clorhexidina, esta presenta mejor eficacia que si se aplicara solo el 0,2%.

Published: June 2018

In the present review, we describe three hot topics in cancer research such as circulating
tumor cells, exosomes, and 3D environment models. The first section is dedicated to
microfluidic platforms for detecting circulating tumor cells, including both affinity-based
methods that take advantage of antibodies and aptamers, and “label-free” approaches, exploiting
cancer cells physical features and, more recently, abnormal cancer metabolism. In
the second section, we briefly describe the biology of exosomes and their role in cancer, as
well as conventional techniques for their isolation and innovative microfluidic platforms. In
the third section, the importance of tumor microenvironment is highlighted, along with techniques
for modeling it in vitro. Finally, we discuss limitations of two-dimensional monolayer
methods and describe advantages and disadvantages of different three-dimensional tumor
systems for cell-cell interaction analysis and their potential applications in cancer management.
Dual Inhibitors as a New Challenge for Cancer Multidrug Resistance Treatment
Authors: Stanković Tijana , Dinić Jelena , Podolski-Renić Ana , Musso Loana , Burić Sonja Stojković , Dallavalle Sabrina , Pešić Milica
Published: June 2018

Background:

Dual-targeting in cancer treatment by a single drug is an unconventional approach in relation to drug combinations. The rationale for the development of dualtargeting agents is to overcome incomplete efficacy and drug resistance frequently present when applying individual targeting agents. Consequently, -a more favorable outcome of cancer treatment is expected with dual-targeting strategies.

Methods:

We reviewed the literature, concentrating on the association between clinically relevant and/or novel dual inhibitors with the potential to modulate multidrug resistant phenotype of cancer cells, particularly the activity of P-glycoprotein. A balanced analysis of content was performed to emphasize the most important findings and optimize the structure of this review.

Results:

Two-hundred and forty-five papers were included in the review. The introductory part was interpreted by 9 papers. Tyrosine kinase inhibitors’ role in the inhibition of Pglycoprotein and chemosensitization was illustrated by 87 papers. The contribution of naturalbased compounds in overcoming multidrug resistance was reviewed using 92 papers, while specific dual inhibitors acting against microtubule assembling and/or topoisomerases were described with 55 papers. Eleven papers gave an insight into a novel and less explored approach with hybrid drugs. Their influence on P-glycoprotein and multidrug resistance was also evaluated.

Conclusion:

These findings bring into focus rational anticancer strategies with dual-targeting agents. Most evaluated synthetic and natural drugs showed a great potential in chemosensitization. Further steps in this direction are needed for the optimization of anticancer treatment.
Enhancing Executive Functions Among Dutch Elementary School Children Using the Train Your Mind Program: Protocol for a Cluster Randomized Trial (Preprint)
Authors: Bervoets Joachim , Jonkman Lisa M , Mulkens Sandra , de Vries Hein , Kok Gerjo
Published: June 2018

BACKGROUND

Executive functions are higher cognitive control functions, which are essential to physical and psychological well-being, academic performance, and healthy social relationships. Executive functions can be trained, albeit without broad transfer, to this date. Broad transfer entails the translation of improved cognitive functions to daily life (behaviors). The intervention Train your Mind was designed to train executive functions among elementary school children aged 9 to 11 years, and obtain broad transfer in terms of enhanced physical activity, healthy eating, and socioemotional regulation.

OBJECTIVE

This paper aims to describe the cluster randomized trial to test the effectiveness of the Train your Mind intervention.

METHODS

Train your Mind was integrated into the existing school curriculum for 8 months (25 weeks excluding holidays). The effectiveness of the intervention was tested in a cluster randomized trial comprising 13 schools, 34 groups (school classes), and 800 children, using a battery of 6 computer tasks at pre- and postmeasurement. Each of the 3 core executive functions was measured by 2 tasks (Flanker and Go/No-Go; N-Back and Running Span; Attention Switching Task and Dots/Triangles). Moreover, we administered questionnaires that measure emotion-regulation, cognitive errors, physical activity, dietary habits, and the psycho-social determinants of diet and physical activity. Body mass index was also measured. Multilevel analyses will account for clustering at the school and group levels, and randomization took place at the school level.

RESULTS

Results are currently being analyzed.

CONCLUSIONS

The main purpose of this study is to test Train your Mind’s effectiveness in enhancing executive functions. Second, we investigate whether increased executive functions lead to improved physical activity and healthy eating. If found effective, executive function training could easily be integrated into school curricula everywhere, and as such, boost health, academic performance, and emotion-regulation of elementary school children, in a cost-effective manner.

Alcance y derrotabilidad de las reglas jurídicas
Authors: Pulido Ortiz Fabio Enrique
Published: June 2018

En este artículo se analiza el alcance práctico de las reglas (AP) y su relación con las reglas de derrotabilidad (RD). Primero, se afirma que determinar el AP depende tanto de las reglas secundarias del sistema jurídico como del dominio limitado de las autoridades. Segundo, se muestra que las reglas secundarias pueden incluir o excluir las razones justificatorias de las reglas y, en esos contextos en donde esas razones no son excluidas, es posible que ellas generen excepciones implícitas, las cuales no pueden ser identificadas de manera anticipada. Tercero, se concluye que la derrotabilidad de la reglas es una propiedad contingente que depende de dos elementos: a) la presencia de razones justificatorias que no son excluidas de acuerdo con las reglas secundarias y el límite de dominio de las autoridades, y b) que las consecuencias normativas de esas razones no puedan ser identificadas ex-ante.
Ética de la virtud y profesiones jurídicas
Authors: Aránguez Sánchez Tasia
Published: June 2018

¿Qué virtudes debe tener la persona juzgadora? ¿Qué hay de la abogacía? Este trabajo está enfocado en el estudio de la naturaleza ética de la profesión jurídica, planteando la necesidad de modelos de excelencia orientados a la promoción de la justicia. Frente a una visión que concibe al derecho como el arte de persuasión, en este trabajo se explora el paradigma clásico de la “retórica de la virtud”, formulada por Cicerón y Quintiliano. Desde una postura que asimila la tarea judicial como un ejercicio abstracto, este artículo se enfoca en el modelo judicial compasivo defendido por Aristóteles.
Educación para las diversidades; la vocación de la universidad, una plaza (cité) expuesta para la fuerza
Authors: Raphael Lucía
Published: June 2018

Este ensayo desarrolla el acercamiento entre las reflexiones de dos filósofos contemporáneos, Martha Nussbaum y Jaques Derrida, quienes encuentran en la educación y en la universidad las trincheras necesarias para regresar su lugar a las humanidades, comenzando por el derecho, pero no sólo su humanidad, sino su papel fundamental para la concientización y reapropiación de la dignidad que todo ser humano conlleva, y cuya realidad se está viendo menguada hasta su propia negación por el sistema político actual, reinante de manera global en el planeta, el cual lo conduce hacia su destrucción. Es una invitación a comprender la riqueza que implican las diversidades, las diferencias, las alteridades, y el compromiso que la universidad, desde su vocación primera, comprende desde la Edad Media de ser el espacio de todas las preguntas y también por qué no, de los silencios, y lo que se requiere es guardarlos. El derecho tiene la responsabilidad de reconocer en su razón de ser las aspiraciones del Siglo de las Luces, de libertad, de igualdad, de laicidad, y nos corresponde a nosotrxs como estudiantes de esta disciplina defender y entender los conceptos de un alto valor humanista, que lo exponen como defensor de la dignidad humana y como límite para el poder desmedido y a la intolerancia que lleva a la humanidad a la destrucción y al odio del otro, de los desconocido, y nunca, ojalá fuera posible, lo contrario, como suele ocurrir.

O mar, a nau, a batalha: a sobrevivência das formas na 'Antologia da memória poética da Guerra Colonial'
Authors: Vasconcellos Lisa Carvalho
Published: June 2018

A Antologia da memória poética da guerra colonial, livro publicado pelos lusitanistas Roberto Vecchi e Margarida Calafate Ribeiro em 2011, é o mais recente esforço no sentido de coletar e dar significado ao enorme corpus poético que foi produzido a partir dos conflitos travados entre Portugal e suas ex-colônias nas décadas de 1960 e 70. Entre os muitos eixos temáti­cos e formais que atravessam os poemas e poéticas recolhidos no livro, o resgate e a reproposição da tradição literária portuguesa talvez sejam os principais. Nas mais de seiscentas páginas do volume, as tradições do pas­sado – as Cantigas de Amigo, as crônicas de navegação, a épica camoniana, as figuras históricas e os mitos heroicos – são revistas de modo crítico e inventivo. Mais do que uma releitura paródica do passado, a presença de elementos arcaicos e tradicionais na Antologia denota a sobrevivência de formas e tensões (cf. Aby Warburg) na cultura literária de Portugal, que se renova e reinventa a partir quase sempre das mesmas questões (o mar, a conquista, a saudade e a destruição).---DOI: http://dx.doi.org/10.22409/abriluff.2018n20a483

Este artigo pretende explorar as ligações entre literatura colonial e antro­pologia durante as primeiras décadas do século XX. Através da análise da obra Pretos e Brancos (1926) de Brito Camacho é minha intenção demons­trar que algumas das obras vencedoras do Concurso de Literatura Colonial se encontram imbuídas de um olhar antropológico fazendo com que lite­ratura colonial e antropologia se tivessem constituído como dois “saberes” coloniais interligados desde a sua génese. Assim sendo, ambos os “saberes” – literário e antropológico –funcionaram no início do projeto colonial com o objetivo de construção e legitimação do império colonial português.---DOI: http://dx.doi.org/10.22409/abriluff.2018n20a494
O singular enfrentamento à ideologia colonial da colecção “autores ultramarinos ” da Casa dos Estudantes do Império
Authors: Mata Inocência Luciano dos Santos
Published: June 2018

Tendo a CEI nascido sob os auspícios do então ministro das Colónias de Portugal, Vieira de Machado, como consagração da política de enaltecimento e defesa do império colonial, pode parecer paradoxal que uma instituição que era suposto funcionar como “triunfo do espírito português” pudesse gerar tantos cartuchos fracturantes da consciência histórica do regime. Um desses cartuchos, para além do Centro de Estudos Africanos (criado pelos estudantes da CEI, mas que não funcionava no espaço da CEI), foi a Colecção “Autores Ultramarinos”, em que, não obstante a designação, foram publicadas as obras mais emblemáticas da literatura anticolonial africana. O objectivo deste artigo é revelar os meandros dessa orientação editorial e a sua relação com a “questão colonial” e como ela funcionou como uma estratégia para enfrentar a violência da ideologia colonial cujo objectivo era a subalternização das identidades africanas.---DOI: http://dx.doi.org/10.22409/abriluff.2018n20a495

Published: June 2018

Phleum pratense (L.) is the important forage grass species in Serbia. The
study was conducted on 20 autochthonous population of Phleum pratense (L.),
originating from Western Serbia. Plant height, protein content and crude
cellulose content had a high direct impact on yield. Populations of PP16,
PP20, PP2 and PP9 had the significantly higher yield of the raw matter
compared to all the tested population and the highest values for the other
evaluated parameters, also. The average yield of crude biomass was positive
statistically highly significantly correlated with plant height (r=0.87**),
and positively significantly correlated with a content of crude proteins and
positive non significant correlated with crude cellulose (r=0.42 ns). Based
on obtained values and by the appropriate choice of selection methods, we
conclude that we have excellent genotypes, PP16, PP20, PP2 and PP9 for a
successful selection process in order to obtain new high yielding varieties
of Phleum pratense.

An exploratory research work was conducted to study the character association
and their direct and indirect effects on grain yield in three bacterial
blight resistance genes introgressed segregating populations (F2) in rice.
Data for yield and five other traits which were component of yield were
recorded in 449 F2 individuals in all three crosses. Thousand grain weight
was highly correlated with single plant yield in (r=0.95**, p<0.01) CB 174 R
? IRBB 60> (r=0.48**, p<0.01) CB 87 R ? IRBB 60> (r=0.44**, p<0.01) TNAU CMS
2B ? IRBB 60. Thousand grain weight was exhibited important yield
determining component for CB 174 R ? IRBB 60 (0.92) and CB 87 R ? IRBB 60
(0.45), and panicle length for (0.39) TNAU CMS 2B ? IRBB 60 by direct
effect. The genetic information derived from our study could be useful to

Published: June 2018

Genetic relationships among 12 taxa from subgenera Pinus and Strobus were
studied through fourteen microsatellite markers, previously developed for
Pinus taeda. To our knowledge, this is the first comparative study of pines
using nuclear EST-microsatellites (EST-SSRs). The total number of detected
alleles in all investigated taxa was 72 (5.14 in average). The numbers of
alleles per locus and PIC values for estimated markers ranged from 3 to 7,
and from 0.43 to 0.81, respectively. Presented results are in accordance
with majority of previous genetic investigations and infrageneric
classification of genus Pinus up to the sectional level, while subsectional
position of some species has still not dismissed, especially regarding
relict ones. According to nuclear EST-SSRs, Pinus heldreichii is in
early-diverging position within subsection Pinaster and shows the greatest
closeness with P. halepensis, while Pinus peuce doesn't have basal position
within subsection Strobus being more close to P. strobus than to P.
wallichiana. Furthermore, the closest connections in subsection Pinus were
found between two Pinus nigra subspecies (dalmatica and nigra) as well as
between P. sylvestris and P. mugo.
Using the Griffing’s experimental design method I, model II. Apple breeding - a case study as a proposed methodology of the statistical and genetic analysis
Authors: Sestraş Adriana , Jäntschi Lorentz , Bolboacă Sorana
Published: June 2018

The diallel mating design is widely used in plant breeding to estimate
combining ability of genitors and useful genetic parameters. In this work, a
complete diallel mating design with four apple cultivars used as genitors
was set, in order to elaborate a pattern for a quantitative trait,
respectively the height of apple hybrids, measured at three months after
emergence. Griffing?s method I, model II, with random effects, also known as
complete diallel mating design, was included in a broader context of a
methodology for both statistical and genetic analysis of the experimental
data. An algorithm was developed based on the proposed methodology and
tested on the experimental data as well as on other two simulated scenarios
of complete diallel mating design with respectively three and seven parents
fed with random values. The results have illustrated the pattern suitability
for the quantitative inherited trait as was the height of the apple
seedlings, respectively the speed of growth of the very young plants. In
addition, the proposed algorithm can help young researchers to understand
and use adequately for different similar traits the complexity of
statistical and genetic analysis of the full diallel mating design. The
information obtaining using diallel crosses offers the breeders the
possibility to choose the appropriate breeding and selection strategies for
quantitative traits.
Different multivariate analysis for fruit traits in sweet pepper breeding
Authors: Danojevic Dario , Medic-Pap Sladjana
Published: June 2018

Pepper is very popular vegetable crop in Southeast Europe and in Serbia as
well. Wide genetic variability is essential in pepper breeding programs. The
aim of this study was to evaluate variability for the most important fruit
traits and differences between 28 sweet pepper genotypes from the working
collection from the Institute of Field and Vegetable Crops (Novi Sad,
Serbia). The following traits were analyzed: fruit weight (g), fruit length
(cm), fruit diameter (cm), fruit index, number of locules, number of apexes,
pericarp thickness (mm), and total soluble solids (?Brix). Results confirmed
great variability in evaluated pepper fruit traits. Genotypes were separated
into individual groups based on fruit characteristics. According to our
research, hierarchical cluster analysis represented differentiation among
groups of genotypes more clearly than PCA, but not comparing to k-means.
Hierarchical cluster analysis showed the similarity between genotypes, but
k-means clustering did not. Genotypes from group 3 will be used in breeding
for higher fruit weight and group 6 for thicker pericarp.

Published: June 2018

The diversity and phylogeny of 30 rhizobia isolated from nodules of faba bean
plants grown on 5 geographic regions located in the East Azerbaijan province
of Iran were examined using rep-PCR fingerprinting, sequence analysis of 16S
rRNA accompanied with nodC genes. Based on cluster analysis of rep-PCR
fingerprints, faba bean rhizobia isolates were differentiated into five
clusters (A to E) at 80% similarity level. The cophenetic correlation
coefficient for the dendrogram obtained from the combined dataset of BOX and
ERIC primers was 0.942. The percentage of polymorphic loci was 59.2% using
the BOX-PCR primer and 67.3% using the ERIC-PCR primers. The data obtained
by rep-PCR fingerprinting showed high apparent correlation between genetic
diversity and geographical origin of the isolates. The phylogenetic analysis
based on 16S rRNA and nodC sequences showed that representative isolates
were closely related to R. leguminosarum bv. viciae and R. fabae. To the
best of our knowledge, this is first report of isolation and
characterization of R. fabae from Iran.
Polymorphism of the melanocortin receptor gene and its association with egg production traits in Lohmann Brown chickens
Authors: Aggag Sarah , El-Sabrout Karim
Published: June 2018

The melanocortin gene (MC4R) was proposed as a candidate gene in this study
for egg production traits (yield and weight) in Lohmann Brown hens. Two
different primers from MC4R gene (MC4R-1 and MC4R-2) were investigated. DNA
from blood samples was extracted to amplify the MC4R gene and the purified
PCR products were sequenced. Alignment of sequence data from each group
revealed that there is a variation in MC4R-1 at nucleotide 22 (T-G) (sense
mutation) for high egg weight. Hens with the genotype produced
significantly (P<0.05) higher egg weight compared to hens with the AA and BB
genotypes. There was no significant (P>0.05) effect of this mutation on egg
yield. There was no variation detected in MC4R-2. The detected mutation and
the analysis of egg production means revealed a significant association
between MC4R polymorphism and egg weight. The MC4R-SNP could be considered
as a useful marker in chicken selection especially for egg weight.
Investigation of association between the human neuropeptide Y gene Leucine7Proline polymorphism and obesity in a population from Turkey

Published: June 2018

Obesity, an important public health issue, is a risk factor for many diseases
and has been associated with many genes. The aim of this study was to
investigate if there is an association between an NPY gene polymorphism,
Leu7Pro, and obesity and/or obesity-related phenotypes. A total of 84 obese
cases (45 female and 39 male) and a total of 77 non-obese control subjects
(38 female and 39 male) were included in this case-control study. Body
weight and height measurements were used for calculation of Body Mass Index
(BMI) and the ones in the ranges of 18 to 25 kg/m2 were considered normal
and the ones 30 kg/m2 and over were considered obese from the subjects.
Minor allele frequency for Leu7Pro polymorphism was 3.5% and it was found to
be associated to increased obesity in the population studied. No significant
differences were observed between genotype distrubutions and allele
frequencies for both obese and non-obese subjects. However, mean BMI values
were found to be higher (38,88 ? 2,96) in obese cases having Pro7 allele
than non carriers of this allele (35,37 ? 5,16), (p=0.044). This is the
first study in a Turkey population which supports the role of Leu7Pro
polymorphism in obesity. Further studies with larger sample sizes may
confirm these findings and can contribute and shed light on the genetic
factors playing a part in Turkey population.
From proteomics to ionomics: Soybean genetic improvement for better food safety
Authors: Watanabe Daisuke , Losák Tomás , Vollmann Johann
Published: June 2018

Soybean is a major protein and oilseed crop for food and livestock feed
production, which is increasingly utilized in the food industry due to its
favorable protein content and a superior overall seed composition with a
high nutritional value. However, some of the soybean seed components have
the potential to reduce the value of soy-food products as they are posing
different food safety risks. Therefore, the objective of the present review
was to evaluate options of soybean genetic improvement for the development
of food-grade soybeans with a focus on food safety traits. To date, useful
genetic variation in soybean germplasm collections and breeding materials
has been described for protein components such as allergens or
anti-nutritional factors, for fatty acid composition relevant to food
safety, and for toxic heavy metal accumulation. Due to the progress in
genomic research, genetic markers are available for assisting the
introgression of major food safety traits into breeding populations, and the
genetic mechanisms behind particular food safety traits have been clarified.
Moreover, analytical methods from the fields of proteomics or ionomics are
helpful for validating selection response and for monitoring quality
features across genotypes. As consumer demand for food safety is steadily
increasing, plant breeding approaches are gaining in importance as they can
provide high-quality soybean raw materials to the food industry. For
implementing better food safety on the consumer level, however, it appears
that coordinated action between plant breeding and genetic research, food
processing and marketing of products needs to be developed.

New proposals for organization of knowledge and their role in the development of databases for history of science
Authors: Alfonso-Goldfarb Ana M. , Waisse Silvia , Ferraz Marcia H.M.
Published: June 2018

As is known, the digital era brought new possibilities for creation, organization and work with large databases. However, some problems make such large databases difficult to manage, as e.g., lack of definite standards, or perhaps even full impossibility to develop any standard at all due to the complexity of the data. This certainly is the case of databases in the humanities, especially in regard to fields in which the aspect of temporality is constitutive. In this paper we discuss models for organization of knowledge, with particular attention to the modern fate of the traditional ‘trees of knowledge’, the emergence of decentered network models and new possibilities that emerged together with the digital humanities. We conclude with some considerations on very recent initiatives to solve the problem posed by temporality in large textual corpora.
From the Golem's Jewish Myth to IBM's responsive Watson: where are we going?
Authors: Goldfarb Jose Luiz , Souza Odecio
Published: June 2018

Since data mining uses notions from areas such as cybernetics and artificial intelligence, it is worth evoking here ages-old fears elicited by the idea of automatons created to help humans, but which eventually turned against their creators. Examples might range from the Jewish myth of the Golem to the more famous Frankenstein, Hal from Stanley Kubrick’s 2001: A Space Odyssey (1968), and the more recent Her, by Spike Jonze (2013). In this discussion we pay special attention to the fact that in the 21st-century it seems to be less a matter of creating an individual cybernetic creature, than of the rise of social networks, which are alluded by many as collective intelligence. Such collective intelligence might involve, for instance, the responsive ability of IBM’s Watson.
History of science: the problem of cataloging, knowledge indexing and information retrieval in the digital space
Authors: Bromberg Carla
Published: June 2018

Text-based and multimedia documents in and for history of science are displayed in libraries and ought to be organized to make knowledge and information on history of science accessible. The traditional approach to the organization of and access to knowledge and information was expressed by classification schemes primarily influenced by philosophical traditions, and then mostly based on the literary warrant principle. Within this context, the scholarly and scientific literature was seen as representing facts about knowledge and structures of knowledge. Cataloging and classification were essential to provide users access to information. Cataloging elements consist of bibliographic description, subject analysis and classification. Currently, within the digital environment, not only text-based documents, but documents of all sorts must be included, classified and organized in order to be browsed. In this paper I call the attention to some of the improvements and challenges that currently affect the relationship between catalogs, knowledge organization, classification and information retrieval. As an example I mention the catalog-interface that is being developed for the digital library of CESIMA-Brazil.
Amor, relacionamentos amorosos e poliamor na perspectiva de jovens universitários e idosos
Authors: Hatakeyama Natani Harumi , Almeida Thiago De , Falcão Deusivania Vieira da Silva
Published: June 2018

Este estudo teve por objetivo investigar as crenças de jovens universitários e idosos sobre: os conceitos por eles atribuídos à palavra amor, e o que entendem como relacionamentos amorosos, sejam estes monogâmicos, poligâmicos ou poliamorosos. Trata-se de um estudo exploratório, transversal e descritivo. Participaram da pesquisa sete jovens universitários, com idades variando entre 22 a 42 anos e cinco idosos, e idades entre 62 e 68 anos. A amostra foi obtida por conveniência. Observou-se que os conceitos de amor, relacionamentos amorosos, e poliamor são heterogêneos, sendo influenciados pela vivência de cada indivíduo. Alguns fatores externos podem ter contribuído para a formação da concepção do indivíduo, como a cultura, o grupo social, a época vivida etc.

Observou-se que os impactos psicossociais estão relacionados à exclusão, ao sofrimento psíquico, à falta de autonomia e de planos futuros, aos sentimentos de abandono, patologias, distúrbios do sono e uso de psicofármacos. Assim, se faz necessária a produção de mais estudos, visando a promover a saúde e qualidade de vida de idosos institucionalizados.
Doğru Taban Gübre Seçiminde İhmal Edilen Seçenek: 20.32.0.+15 (SO3) + Zn Gübresi ve Toprak Analiz Desteği
Authors: Kaplan Mustafa , Maltaş Ahmet Şafak
Published: June 2018

Öngörü çalışmalarının zenginliği, çoğu zaman,
öngörü kalitesini artırır. Ancak Türkiye kimyasal gübre tüketimlerinin
geleceğine yönelik çalışmalar azdır. Bu makaleyle, 1999 yılında önerilen ve
2004 yılından itibaren üretilmeye başlanan bir kompoze gübrenin, henüz tahmin
edilen düzeyde tüketilmiyor olmasının neden ve sonuçları tartışılmıştır.
Türkiye’de çiftçiler özellikle hububat üretiminde ekim öncesi veya ekimle
gübrelemede çoğunlukla azot ve fosforu birlikte içeren kompoze gübreleri tercih
etmektedirler. Bu tercih,  çiftçileri DAP
ve 20.20.0 kompoze gübrelerini yaygın olarak kullanmaya yönlendirmiştir. 1999
yılında önerdiğimiz,  2004 yılından bu
yana üretilen 20.32.0. 15(SO3)+Zn gübresi, bazı hububat alanları için çok daha
uygun azot fosfor dengesi sağlayan doğru bir alternatiftir. Ancak bilinirliği
çok sınırlıdır. Yıllık tüketim miktarının son 3 yıl ortalaması yaklaşık 19 bin
ton düzeyindedir ve bu durum beklentilerimizin altındadır. Toprak analizine
dayalı, nitelikli gübreleme tavsiyeleri sayısının artışı; bu ve bu gübredeki
N/P205 dengesine yakın özellikte üretilecek gübrelere
artan miktarlarda tüketim şansı verecektir. Olmasını beklediğimiz bu artış,
dengesiz azot-fosfor kullanıma bağlı ekonomik kayıpları azaltabilecektir. Bilgi
ve gözlemlerimizin hemen tamamı Türkiye’de toprak ve bitki analiz desteğinin
çok özel bir değere sahip olduğuna işaret etmektedir.  Kimyasal gübre tüketim desteğinden daha
öncelikli olarak, toprak ve bitki analiz desteğinin uygulama kalitesi
geliştirilmelidir. Bu yolla gübrelemelerin analiz sonuçlarına dayalı olarak
yapılmasını gerçekleşebilecektir. Sonuçta kimyasal gübre kullanım etkinliği
artacaktır.
Samandağ Kumsalı Yeşil Deniz Kaplumbağası (Chelonia mydas) Yuvalarında Memeli Predasyonunun Zamansal ve Mekansal Değişiminin İncelenmesi
Authors: Sönmez Bektaş
Published: June 2018

Yuva predasyonu, birçok nesli tükenmekte olan kuş ve
sürüngen türünün korunması için önemli bir pratik zorluktur ve yavru başarısını
azaltma ve tehdit altındaki popülasyonların iyileşmesini yavaşlatma potansiyeline
sahiptir. Yuva predasyonunun zamansal ve mekansal değişiminin tahmin edilmesi
predasyon yönetimini optimize etme potansiyeline sahiptir. Bu çalışmada,
Samandağ kumsalında yeşil deniz kaplumbağası (Chelonia mydas) yuvalarında memeli predasyonunun zamansal ve
mekansal değişimleri araştırıldı. 2012 ve 2017 yılları arasında 733'ü metal
ızgaralı kafes ile korunan, 231'i ise metal ızgara ile korumaya alınmamış
kontrol yuvaları olan toplam 964 yuva araştırıldı. En etkili yuva predatörü Çakal
olarak tespit edildi. Yuvaların metal ızgaralı kafes ile korunması yavru
başarısını etkin bir şekilde arttırdı. Predasyona uğrayan yuva sayısı yıllara
göre pozitif bir eğilim gösterdi, ancak bu eğilim istatistiksel olarak anlamlı
değildi. Predasyon olasılığı kuluçka döneminin sonuna doğru arttı ve deniz ve
bitki örtüsüne olan mesafeye göre mekansal değişimde farklılık ortaya çıkmadı.
Ayrıca, kumsalın sonuna doğru predasyon olasılığı arttı. Yuva yoğunluğu ve yuva
derinliklerine bağlı predasyon olma ihtimalinin ileride araştırılması
önemlidir. Ayrıca Samandağ sahilinde baskın yırtıcı olan Çakalların populasyon
ekolojisi ve statüsünün araştırılması da her iki tür için de önemlidir.

Published: June 2018

Bu çalışma farklı kök bakterilerinin (Azot-1,
Azot-2, Fosfor-1, Fosfor-2, Azot+Fosfor), 3 çilek çeşidinde (Albion, San
Andreas ve Monterey) verim ve bazı meyve özellikleri üzerine etkilerini
araştırmak amacıyla yapılmıştır. Çalışmada bakteri uygulamalarından meyve verimi üzerine en
etkili sonuç 99.88 g bitki-1 ile Fosfor-1 uygulamasından elde
edilmiştir. Bakteri uygulaması sonucunda çeşitler arasında en yüksek verim,
93.02 g bitki-1 ile San Andreas çeşidinden elde edilmiştir.  Bakteri uygulamaları bakımından, en yüksek
meyve sayısı 3.48 adet bitki-1 ile Azot-1 uygulamasından elde
edilmiştir. Bunun yanında en fazla meyve sayısı 4.28 adet bitki-1
ile Monterey çeşidindeki Azot-1 grubundan elde edilmiştir. Bakteri
uygulamalarında ortalama meyve ağırlığı bakımından, en yüksek sonucu 30.17 g
meyve-1 ile Fosfor-2 uygulaması vermiştir. Aynı şekilde en yüksek
ortalama meyve ağırlığı 32.38 g meyve-1 ile San Andreas çeşidinde
Fosfor-2 uygulamasında belirlenmiştir. Suda çözünür kuru madde
içeriği açısından bakteri uygulamalarından en yüksek değer %10.02 ile
Azot-1 uygulamasında belirlenmiştir. Fosfor-2 uygulamasında en yüksek suda
çözünür kuru madde miktarı %10.98 ile Monterey çeşidinde elde edilmiştir.
Bakteri uygulamaları sonucu en yüksek pH değere 3.97 ile Azot-2 uygulamasından
ulaşılmıştır. İncelenen çilek çeşitleri arasında en yüksek pH 9.92 ile Albion
çeşidinde kontrol grubundan elde edilmiştir. Bakteri uygulamalarında en yüksek
titre edilir asitlik %0.92 ile Fosfor-2 uygulamasında belirlenmiştir. Çilek
çeşitlerinde ise en fazla titre edilir asit %1.18 ile San Andreas çeşidinde
Fosfor-2 uygulamasından elde edilmiştir. Çalışma sonucunda incelenen
parametreler bakımından kök bakterisi uygulamalarının verim ve kalite yönünden
faydalı olacağı düşünülmektedir.
