O objetivo deste estudo foi elaborar formulações de bolo com farinha de banana verde (Musa sp.) e frutooligossacarídeo, e avaliar o efeito da substituição da farinha de trigo pela farinha de banana verde, no que se refere às características sensoriais e químicas do produto proposto. Foram elaboradas três formulações de bolo, que foram avaliadas microbiologicamente (bolores e leveduras, coliformes totais, coliformes termotolerantes e Salmonella sp.), sensorialmente (preferência, aceitação e intenção de compra) e quimicamente (umidade, lipídios, proteínas, cinzas, fenólicos totais, radical difenil-picril-hidrazina e redução do ferro). Além disso, foram determinados os carboidratos totais e o percentual calórico dos bolos. As três formulações de bolo, estavam microbiologicamente seguras, diferiram sensorialmente no que se refere a aparência e a cor, sendo esses parâmetros estatisticamente iguais entre as formulações 1 e 3 e formulações 2 e 3. A composição química variou a umidade (22,82 a 28,67), os fenólicos totais (124 a 267,08) e a redução do ferro (4,45 a 10,18). A substituição da farinha de trigo por farinha de banana não influenciou a qualidade microbiológica dos bolos, a preferência sensorial e potencial de consumo, porém exerceu pouco efeito na aceitação sensorial e na composição química, sendo assim, diante das características observadas nas formulações de bolo com farinha de banana e frutooligossacarídeo indicam que são potencialmente atrativas do ponto de vista comercial e nutricional.

Published: April 2019

Este trabalho teve como objetivo avaliar a qualidade microbiológica de sorvetes consumidos em Frutal/MG, por meio da determinação de coliformes totais e termotolerantes, Staphylococcus coagulase positiva e coagulase negativa, e Salmonella spp. Foram avaliadas 40 amostras de sorvetes, de 5 sorveterias, coletadas aleatoriamente. As amostras foram diluídas em água peptonada, nas diluições 10-1 a 10-4. Os coliformes totais foram determinados em Caldo Verde Bile Brilhante, a 35 ºC por 24-48h. Dos tubos positivos, uma alça foi semeada para o meio EC para determinação de coliformes termotolerantes, a 45 ºC, pelo mesmo período. A contagem de Staphylococcus coagulase positiva foi feita em meio Baird Parker e a contagem de Salmonella spp foi feita em meio Salmonella Shigella (SS). Observou-se que 11 amostras (27,5%) apresentaram índices acima do permitido pela legislação para coliformes termotolerantes (>50 NMP/g). Uma amostra (2,5%) estava contaminada por Staphylococcus coagulase positiva. Em uma amostra (2,5%) também foi detectada presença de Salmonella spp. No total, 14 amostras (35,0%) estavam impróprias para consumo, por estarem fora dos padrões para pelo menos um dos microrganismos avaliados. Os resultados indicam a necessidade de melhorias das condições de higiene na produção, armazenamento e/ou manipulação, nos estabelecimentos onde houve contaminação dos sorvetes, uma vez que o consumo de sorvetes fora dos padrões microbiológicos pode representar riscos à saúde dos consumidores.

Published: April 2019

Os sistemas de manejo do solo podem resultar em alterações físicas no solo como a formação de camadas compactadas. Um dos atributos físicos mais adotados como indicativo da compactação do solo têm sido a resistência mecânica do solo à penetração, por apresentar relações diretas com o crescimento das plantas e por ser mais eficiente na identificação de estados de compactação do solo. Nesse sentido, objetivou-se avaliar a resistência mecânica do solo à penetração em dois sistemas de manejo do solo, por meio de utilização da técnica de penetrometria. O experimento foi realizado em área da Universidade Federal Rural da Amazônia, Campus de Parauapebas. O delineamento experimental utilizado foi inteiramente casualizado com dois tipos de manejo: sistema de plantio direto (SPD) e sistema de plantio convencional (SPC), com 40 repetições para cada tratamento. A resistência do solo à penetração (RP) foi mensurada utilizando-se o Medidor Eletrônico de compactação do solo por pressão, modelo PenetroLOG – PLG 1020 da marca Falker, na profundidade de 0,00 a 0,40m a qual foi subdividida em oito camadas de 0,05 m para avaliação. A adoção dos sistemas de plantio direto e plantio convencional ocasionaram oscilação na resistência mecânica do solo à penetração ao longo das camadas do solo. No SPC foi observada menor RP quando comparado ao outro tratamento, na profundidade 0,00 - 0,10 m. Diferente disso, no SPD as subcamadas de 0,15 - 0,25 m apresentaram menores valores de RP e maior umidade do solo. A partir da profundidade de 0,20 m ambos os sistemas apresentaram indicativo de camadas compactadas do solo.

Published: April 2019

O estudo da percepção ambiental constitui uma ferramenta capaz de expor a realidade socioambiental de determinadas comunidades através da coleta de informações diretamente com os moradores que vivenciam os problemas, visto que evidencia ações, valores e opiniões, bem como conhecimentos culturais e hábitos. O objetivo deste trabalho foi avaliar a percepção ambiental dos moradores do Distrito de Galante, sobre a utilização das águas do Açude José Rodrigues após o racionamento ocorrido nos entre os anos de 2016 e 2017, uma vez que as águas deste reservatório estão impróprias para o consumo humano. A metodologia foi composta pela aplicação de um questionário semiestruturado contendo questões abertas e fechadas, sendo aplicado a 30 moradores residentes no entorno do açude José Rodrigues. Os resultados mostram que 60% dos moradores afirmaram utilizar as águas do açude no período do racionamento, sendo as águas utilizadas para consumo humano, dessedentação animal, atividades domésticas, etc. Constatou-se que após o fim do racionamento os moradores utilizavam as mesmas águas para dessedentação animal, recreação, pesca e irrigação. Além disso, o açude é utilizado como ponto turístico, movimentando a economia local. Entretanto, essas águas estão impróprias para o consumo humano e para a realização de atividades que dependam da potabilidade da água.

A busca de bioinseticidas vegetais tem se intensificado, visto que os inseticidas naturais não são persistentes e degradam com maior velocidade que os sintéticos sem deixar resíduos nos alimentos ou no meio-ambiente. Objetivou-se com este trabalho avaliar a ação repelente de óleos essências e vegetais em pulgão-preto (Aphis craccivora Koch) em cultivares de feijão-fava (Phaseolus lunatus L.). Para realização do experimento, discos foliares foram imersos durante 30 segundos em uma solução de 0,05% de cada tratamento e a testemunha em água destilada. Em seguida, os discos foliares foram colocados, dois a dois (tratado e testemunha) em placas de petri com tampas contendo abertura no centro coberta com tecido tipo “voil”, contendo solução ágar-água a 1%, unidos por uma tira de papel. No retângulo de papel foram colocados adultos ápteros de A. craccivora. Foram testados os óleos essenciais: alecrim (Rosmarinus officinalis), copaíba (Copaifera langsdorfii), menta (Mentha L.) e citronela (Cymbopogon winterianus) e três óleos fixos de pequi (Caryocar brasiliense), girassol (Helianthus annuus) e mamona (Ricinus communis). Os dados coletados foram registrados no período de 48h. O número de fêmeas atraídas e de ninfas produzidas, foram analisados pelo teste não-paramétrico x2 (qui-quadrado). O óleo essencial de C. winterianus teve maior repelência e menor produção de ninfas, o óleo de R. communis não apresentou efeito significativo de repelência, aumentando a produção de ninfas e os óleos essenciais R. officinalis, C. langsdorfii e Mentha L. e os óleos vegetais C. brasiliense e H. annuus, apresentaram efeito significativo na redução de ninfas.

Published: April 2019

Introduction: Beta-thalassemia is one of the most prevalent inherited blood diseases among Iranians. The aim of this study was to elucidate the chromosomal background of beta-thalassemia mutations in Esfahan province, Iran.
Materials and Methods: In this study, we investigated three frequent mutations (c.315+1G>A, c.93-21G>A and c.92+5G>C in β-globin gene, the frequency of RFLP haplotypes, and LD between markers at β-globin gene cluster) in 150 beta-thalassemia patients and 50 healthy individuals. The molecular and population genetic investigations were performed on RFLP markers HindIII in the c.315+1G>A of Gγ (HindIIIG) and Aγ (HindIIIA) genes, AvaII in the c.315+1G>A of β-globin gene and BamHI 3' to the β-globin gene. All statistical analyses were performed using Power Marker software and SISA server.
Results: Fifty percent of beta-thalasemia patients were associated with these mutations. Haplotype I was the most prevalent haplotype among beta-thalassemia patients (39.33%) and normal individuals (46%). The commonest c.315+1G>A mutation in our population was tightly linked with haplotype III (43.75%) and haplotype I (31.25%). The second prevalent mutation, c.92+5G>C, was 90%, 6.66%, and 3.33% in linkage disequilibrium with haplotypes I, VII, and III, respectively. The c.93-21G>A mutation indicated a strong association with haplotype I (80%).
Conclusion: Our study participants like beta-thalassemia patients from Kermanshah province was found to possess a similar haplotype background for common mutations. The emergence of most prevalent mutations on chromosomes with different haplotypes can be explained by gene conversion and recombination. High linkage of a mutation with specific haplotype is consistent with the hypothesis that chromosomes carrying beta-thalassemia mutations experienced positive selection pressure, probably because of the protection against malaria experienced by beta-thalassemia carriers.

Published: April 2019

Immunotherapy is the treatment that either boosts the patient’s immune system or uses human-made versions of the normal parts of the immune system to kill lymphoma cells or slow their growth.
A forty-eight-year-old lady with neck nodes, axillary nodes, weight loss and fever diagnosed to have Diffuse Large B-Cell Lymphoma (DLBCL) in December 2009 was treated with 6 cycles of R-CHOP, and her treatment was completed in May 2010. After 2 years in July 2012, the patient developed similar symptoms and received salvage chemotherapy with R-DHAP, and her treatment was completed in January 2013. After one and a half years, in August 2014, the patient again had relapsed DLBCL. She was treated with R-ICE 4-cycles and rendered disease-free following allogeneic HSCT in June 2015. But in December 2016, the patient again developed isolated axillary lymphadenopathy and relapsed DLBCL was confirmed by HPR and IHC. This time, the patient was unwilling to go on chemotherapy, but after counselling about the new drug, Nivolumab, she became convinced, and her treatment was started with 3mg per kg every 2 weeks. After 4 cycles, she had a complete response and is now being treated with the same treatment without any symptoms of the disease or any adverse drug reactions. Nivolumab was well tolerated and exhibited antitumor activity in extensively pretreated patients with relapsed or refractory B- cell lymphomas. Additional studies are ongoing to learn more about the use of Nivolumab in these diseases.

Published: April 2019

Background: Caring is one of the main concepts in nursing and its modes of delivery in different diseases have been widely studied. Hematopoietic Stem Cell Transplantation (HSCT) is a novel, complex, and time-consuming clinical intervention which is applied as a final medical choice in several life-threatening diseases. The aim of the current study was to explore the process of caring for patients undergoing HSCT.
Materials and Methods: In this article, we present a qualitative research study conducted between 2011 and 2013 in accordance with the procedures of grounded theory methodology. Data were gathered by interviewing and observing health professionals involved in HSCT process, as well as patients and their families. The study participants consisted of 18 HSCT nurses, 2 physicians, 12 patients, and 7 members of patients’ families. The initial sampling in the study was purposeful, followed by theoretical sampling. Data were analyzed using the Corbin & Strauss (2008) method.
Results: Four main categories, reflecting 13 sub-categories, were emerged by analyzing the data: struggling of patients between life and death, trying to reduce the chance of patient’s death, enforcing patients’ spirit and caring achievements. The core variable of study, defined as “supporting patients to go through the HSCT process successfully”, represented the nature and efficiency of care delivered to HSCT patients in the study setting.
Conclusion: HSCT patients enter the caring process in the context of life-and-death limbo. The caring strategy in HSCT patients is aimed at trying to reduce the chance of the patient’s death, as well as enforcing patients’ spirit. The HSCT process affects all areas involved in various ways and has some outcomes. The findings and the theoretical conclusions of this study are potentially valuable in improving nursing practice, designing of educational programs and setting of caring policies.

Published: April 2019

We report a case of a 76-year-old male with a history of relapsed and refractory diffuse large B-cell lymphoma (DLBCL).Our patient was initially treated with front line chemotherapy along with central nervous system (CNS) prophylaxis with complete response. He subsequently relapsed, was sensitive to second-line chemotherapy, and underwent autologous stem cell transplantation achieving a complete remission. Only a few months after transplant, the patient suffered his second relapse and was deemed a candidate for Chimeric Antigen Receptor T-Cell Therapy (CAR-T). Given his aggressive disease, combined with the time needed to generate CAR-T cells, a multidisciplinary team recommended to treat our patient with liposomal vincristine in combination with rituximab as a bridge therapy. Durable responses have been seen using liposomal vincristine based on results from a recent phase II trial in heavily pretreated patients with DLBCL1. This therapy was effective in stabilizing and reducing active disease in our patient. This case looks to illustrate the use of liposomal vincristine in combination with immunotherapy in a novel setting bridging highly selected patients with active and refractory lymphoma prior to CAR-T. Moreover, we expanded an additional therapeutic point, highlighting the importance of optimal disease control prior to CAR-T cell harvesting, as recent literature has shown that residual malignant cells in the pheresis product may be inadvertently be transfected with the CAR gene, resulting in resistance and further relapse2.

Gut microbiota is the complex community of microorganisms that live in the digestive tracts of humans and other animals, including insects. The relationship between gut microbiota and human health is mutualistic and altered bacterial composi- tions in fecal and mucosal specimens of colon in patients with cancer compared to healthy subjects were observed. Thereby, studying the gut microbiota, their interactions with the host and their alterations in colorectal cancer (CRC) patients could be helpful to diagnose and treat the disease in earlier stages. In CRC research, the most common samples are feces and tumor tissues. Interestingly, scientists have quite different views regarding gut microbiota composition of feces and tissues. Some believe bacterial populations in feces and mucosa are completely distinct and differ in composition and diversity while some others declare similar variations. Actually, both types of specimens have some advantages and disadvantages in survey of gut microbiota. Fecal samples serve as a noninvasive approach for screening tests while mucosal associated samples are more powerful for identification of bacteria with adenoma and CRC initiation and growth. Here we have discussed the advantages and disadvantages of two type of specimens in CRC investigations and also discussed the similarities and differences of microbial composition between stool and tissue specimens.

Background and Objectives: Pseudomonas aeruginosa is a ubiquitous opportunistic pathogen. The presence of several virulence factors such as exotoxin and exoenzyme genes and biofilm may contribute to its pathogenicity. The purpose of this study was to investigate the presence of toxA, exoU and exoS, the determination of biofilm production and antimicrobial susceptibility patterns among clinical isolates of P. aeruginosa.
Materials and Methods: In this study, 75 isolates of P. aeruginosa were recovered from various clinical specimens. Antimi- crobial susceptibility pattern of isolates were identified. Virulence genes toxA, exoU and exoS were determined using PCR. The ability of biofilm production was assessed.
Results: Antimicrobial susceptibility test showed that 12 strains were resistant to more than 8 antibiotics (17.14%). The most effective antibiotic was colistin as 98.6% of isolates were sensitive. The frequencies of exoU and exoS genes were detected as 36.6% and 55.7%, respectively. In addition, 98.6% of the isolates were biofilm producers. Exotoxin A was detected in sixty-eight isolates (95.7%).
Conclusion: The findings of this study showed that, the presence of P. aeruginosa exotoxin and exoenzyme genes, particu- larly, the exoU gene is the most common virulence factors in the bacterial isolates from urine samples. Biofilm is a serious challenge in the treatment of P. aeruginosa infection.

Background and Objectives: Leptospirosis is a zooanthroponosis caused by the genus of Leptospira. It is an emerging public health problem due to its increasing incidence. The achievement to a vaccine that prevent from entrance of Leptospira interrogans to the deeper tissues of the host is needed. This study aimed to investigate the immunogenicity of LcpA (rLcpA) and LenA (rLenA) recombinant proteins in combination with LTB (rLTB) recombinant protein as an adjuvant against lepto- spiral infection in hamsters.
Materials and Methods: The genes encoding these proteins were cloned into pGH cloning vector and then lenA, lcpA and ltb genes subcloned into pET-15b and pET-28a expression vectors, respectively. The hamsters were immunized with the puri- fied recombinant proteins and challenged with Leptospira interrogans for evaluation of their survival. The antibody respons- es to the recombinant proteins were determined by ELISA. Then, data entered into SPSS software. Statistical Kruskal–Wallis test was used to compare the significant differences among different groups. The groups with significant differences were further analyzed by post hoc tests. The p value < 0.05 statistically was considered significant.
Results: Immunized hamsters with rLenA-plus-rLTB, rLcpA-plus-rLTB and rLenA-plus-rLcpA-plus-rLTB proteins showed
60%, 74%, and 80% survival rates, respectively. A significant amount of interleukin-17 (IL-17), interleukin-4 (IL-4) and gamma interferon (IFNγ) cytokines were produced in immunized hamsters.
Conclusion: Based on our findings, rLcpA and rLenA proteins in combination with rLTB can protect the hamsters against L. interrogans and effectively induce a protective antibody response. Thus, these proteins can be used as an additional pro- phylactic tool against leptospira.

Authors: Rahpeyma Sayyed Shahryar , Raheb Jamshid
Published: April 2019

Background and Objectives: rpoS is a bacterial sigma factor of RNA polymerase which is involved in the expression of the genes which control regulons and play a critical role in survival against stresses. Few suitable vectors are available which could be maintained successfully in Flexibacter chinesis cells and could in particular be used as a suicide vector to make mutation in the rpoS gene. The aim of this study was to investigate if rpoS mutagenesis has impact on bacterial morphology in addition to cell division.
Materials and Methods: A 0.603 kb BamHI-PstI fragment subclone of pICRPOS38Ω was cloned into linearized pLYLO3. The final construct, pLRPOS38 suicide vector, was introduced into Flexibacter chinesis. Then the cytoplasm of mutant strain and wild-type were investigated by transmission electron microscopy.
Results: After successful subcloning of suicide vector into F. chinesis, based on TEM study, it was demonstrated that muta- tion in rpoS gene leads to decomposition of outer membrane of F. chinesis.
Conclusion: A suitable vector to make suicide mutation in rpoS was constructed for F. chinesi.
Towards Critical Realism in Cost Overrun Research
Authors: Alolote Amadi
Published: April 2019

Construction management, as an emergent field of research, is yet to have a recognized methodological orientation, characteristic of other more established domains, and therefore builds on the traditional philosophical assumptions of related natural and social science research. The term “Methodological pluralism,” has thus been used to describe the use of a multiplicity of philosophies and methods, compatible with the study of construction phenomena. This study narrows down the philosophical argument in construction management to within the specific domain of cost overrun research, to systematically articulate the shortcomings in the methodological/philosophical tradition embraced by previous studies. Empirical profiling of cost overrun research reveals the predominance of mono-method studies based on questionnaire survey methods, correlative analysis, and archival data modeling techniques, all of which are underlain by positivism. The study argues that such positivist philosophies, although methodologically valid, cannot adequately explain and provide an in-depth understanding of the contextual drivers in construction organizations, that trigger the more tangible technical constructs, leading to the phenomena of cost growth in projects. Joining in the chorus call for methodological pluralism in construction industry research, this study makes a case for critical realism specifically in the context of cost overrun research.

That’s a summary of our research in Greece and Germany as it concerns with their “labor market”. We examine the 3-polar system in the labor market, State-Company-Citizen. The aim of this paper is to show the bargaining possibilities when there are three involved parties on a labor market and two of them are active decision-makers. The third one is stakeholder who does not directly take part in the decision-making process. We will show possible solutions for increasing the benefit for all three parties. As an introduction, basic statistical data from Greece and Germany will be presented and structured. After this, the different behaviors of the parties in both countries will be regarded and their bargaining success will be illustrated.
Paddy husk compost addition for improving nitrogen availability
Authors: Latifah Omar , Ahmed Osumanu Haruna , Majid Nik Muhammad Abdul
Published: April 2019

Mature compost with good agronomic properties can be used to control nitrogen loss from soil. Soil incubation and leaching experiments were conducted to determine the effects of paddy husk compost addition on controlling ammonium and nitrate
losses from Bekenu Series soil. Retention of soil exchangeable ammonium and available nitrate were significantly improved in soil amended with paddy husk compost treatments compared with urea alone thus, reducing leaching of these ions. At 30 days of
the leaching experiment, ammonium and nitrate losses were highest in urea without paddy husk compost addition compared with co-application of urea and paddy husk compost because the treatment significantly improved retention of soil exchangeable
ammonium and available nitrate. Urea can be co-applied with paddy husk compost to improve release of ammonium and nitrate and to retain nitrogen availability.

Published: April 2019

The main objective of this study is the Population dynamics evaluation of broad bean bruchid Bruchus rufimanus (Coleoptera: Chrysomelidae) in crops beans of Vicia faba within the El Asnam’s region (Algeria). A weekly monitoring of B.
rufimanus was made during breeding diapauses in the laboratory and during their colonization in the parcel of variety of Séville, and then a comparative study had been implemented to characterize the total haemolymphatic protein levels during
diapause and the periods of reproductive activity. The obtained results demonstrated that after the diapause period, the colonization of the field by adults of B. rufimanus coincides with the period of full bloom of the host plant which represents a
trophic source necessary for the reproductive activity. 54 beetles were captured from which 28 were males. Oviposition covering a period of one month and 15 days, with a total of 168 eggs being counted, of which 72 were placed on the low layer pods.
The total hemolymphatic protein content of B. rufimanus was found a high concentration during diapause and varying between 46 to 85.8ìg/ìl. High levels of protein were probably due to the stock of proteins during the larval life of this pest. Protein
levels had decreased significantly in April, reflecting a recovery in the activity and colonization of bean fields for food, sexual partnership, spawning, and other activities. However, throughout the month of May, the protein concentration increased
due to the pollen supply provided by the host plant and weeds present in the agrosystem.

Authors: Singh Surabhi , Paul Bishwajeet , Kumar Archna
Published: April 2019

Y-tube olfactometer study was carried out to observe the orientation response of egg-larval parasitoid Chelonus blackburni Cameron towards various concentrations of volatile cues emitted from three potato varieties and Phthorimaea operculella
Zeller. Volatile cues were subjected to Gas Chromatography-Mass Spectrometry (GC-MS) profiling to identify the signaling molecules present in the pool of volatile cues. Out of 16 selected volatile cues concentrations obtained from plant and host
insect sources, 10 cues acted as significant attractant for C. blackburni. Volatile cues emitted from Kufri Surya in vegetative stage were able to generate highest stimulation in C. blackburni. Among volatiles obtained from larval and adult stage of
P. operculella, adult cues were found to be more efficient in the alteration of foraging behaviour of targeted parasitoid. GC-MS of targeted cues revealed the presence of fifteen saturated hydrocarbons ranging from C12 to C54; varying in
concentrations. Study specified that C. blackburni preferred cues could be exploited to enhance the host searching efficacy during Integrated Pest Management releases.

Authors: Kumar Sanjeev , Upadhyay Sanjay Kumar
Published: April 2019

This paper has analysed the emerging dimensions of food security and trends of crop productivity by using secondary data from 1980-81 to 2014-15 at State level of India and has also identified the impact of climatic and non-climatic variables
on food security and crop productivity. The study revealed that the growth rate of foodgrains and non-foodgrains productivity was found positive except for some crops of non-foodgrains at state level with some fluctuations. In case of food security
and its component, the result showed that there were wide variations across the states during the study period. The panel data regression results also highlighted that the non-climatic factors had positive and significant impact on food security
except urbanization while climatic factors viz. maximum temperature had negative and significant impact and minimum temperature and rainfall had insignificant impact on food security. Furthermore, the impact of climatic and non-climatic factors had a
mixed effect on crop productivity. The paper suggested that there was need to change the policy in term of building sustainable climate resilient technology, enhancing the agricultural infrastructure and optimizing use of inputs for boosting up the
crop productivity and increasing public-private partnerships for sustainable development to solve the problems of food and nutrition at state level.

Published: April 2019

Grain legumes are the important source of dietary protein in tropical regions and insect pests are the major biotic constraints in the production of the grain legumes throughout the country. About 150 species of insects are known to attack
pulse crops in India. Among the insect pests, the sucking pests like aphid, Aphis craccivora Koch; jassid, Empoasca kerri Pruthi; whitefly, Bemisia tabaci Gennadius, thrips,Thrips palmi Karny and flower thrips, Megalurothrips usitatus Bagnall are
known to cause significant damage to the pulse crops and also indirectly acting as a vectors in transmitting the deadly diseases resulting in severe loss in grain yields of the legume crops. The present review highlights the losses caused by the
sucking pests and critically review the literature generated on the bio efficacy of conventional and novel groups of chemical insecticides for the management of sucking pests infesting grain legumes at different locations in India.

Published: April 2019

Core collections contribute to a better utilization of accessions in breeding programs. Eighty-five accessions from a collection of Pisum germplasm were evaluated during 2015 and 2016. Phenotypic values of 12 morphological traits were
measured and genotypic values (BLUP) were calculated. Molecular characterization was performed assaying a total of 15 SSR and 25 SRAP primer combinations. Four Cluster Analysis (phenotypic values, genotypic values, molecular markers and consensus)
and four strategies to determine the number of accessions selected (constant, logarithmic, proportional and maximization strategies) were applied to construct 16 core collections. Validation of the core collections were performed through Mean
difference percentage (MD), Variance difference percentage (VD), Coincidence rate of range (CR) Variable rate of coefficient of variation (VR), Shannon diversity index (SW) and the Taxonomy coverage (TC). The logarithmic strategy with data on
genotypic values was the best strategy, while the least strategy was the proportional strategy with molecular marker data.

Published: April 2019

TThe physiological and phytochemical responses of red amaranth (Amaranthus tricolor L.) and green amaranth (Amaranthus dubius L.) to different salinity levels were determined in two experiments conducted in Vietnam. Both experiments were
performed in a net house involving pot experiments arranged in randomized complete block design (RCBD) with three replications. Two genotypes of amaranth were grown in garden soil, saline soil, 50% garden soil: 50% saline soil and 25, 50 and 100 mM
NaCl. Salinization was imposed at 7, 14 and 21 days after transplanting. Results indicated that salt stress decreased growth parameters and biomass production in all treatments except for 25 mM NaCl. Na+ and Cl- content accumulated in both shoot and
root, however, root had greater NaCl content than shoot. Total phenolics, total flavonoid content and antioxidant activity increased with increasing salinity levels from 25 mM to 50 mM NaCl; however, at 100 mM NaCl, all these parameters decreased.
These results showed that red amaranth was more tolerant to salinity stress than green amaranth.
Effects of some abiotic factors on the exit of poppy root weevils (Ethelcus denticulatus Schrank) (Coleoptera: Curculionidae) from overwintering area
Authors: Islamoðlu M.
Published: April 2019

With this study, it is aimed to determine the effects of some abiotic factors on the exit of poppy root weevils (Ethelcus denticulatus Schrank) (Coleoptera: Curculionidae) from their overwintering area. Poppy root weevils is the most
important harmful pest of poppy fields (Papaver somniferum L.) (Rhoedales; Papaveraceae). According to the findings, the first adults were seen on the soil on March 10, 2014. It has been observed that as the temperature of the air increases, the
number of adults on the soil surface also increases. Thus, it was determined that the number of adults in square meters reached the highest level on April 21, 2014. After this date, it was determined that the number of wintering adults decreased
gradually. While the first insect on the surface of the field was caught on March 09, 2015 in the second year. It was determined that the number of highest poppy root weevils caught on the soil surface and in the traps was on April 13, 2015. After
this date, it was determined that both the trapped insects and their numbers in m2 decreased. There were significant (P£0.05) correlations between the poppy root weevil exit from their overwintering area and soil temperature (r=0.648, r2=0.461, n=84
P=0.000) and temperature (r=0.59, r2=0.277, n=84, P=0.004) whereas there was no significant correlation between it and soil moisture (r=0.310, r2=0.021, n=84, P=0.466), humidity (r=0.32, r2=0.108, n=84, P=0.87) and rain (r=0.38, r2=0.101, n=84,
P=0.73).
