DPP-IV Inhibitory Potential of Methanolic Extract of Pueraria Tuberosa in Liver of Alloxan Induced Diabetic Model
Authors: Srivastava Shivani , Yadav Durgavati , Bhusan Tripathi Yamini
Published: April 2018

DPP-IV is usually found to be over expressed in many pathological conditions of Liver via disturbing immune system, lipid accumulation, ECM degradation etc. The main objective of this work was to explore the effect of methanolic extract of Pueraria tuberosa (PTME) against Alloxan induced liver damage with respect to its potential of inhibiting DPP-IV activity. PTME was prepared through continuous soxhlet extractor. Alloxan injections were given to the same age group with weight range of 80-100 g Charles foster albino male rats at the dosage of 120mg/kg bw. Rats were divided into five groups. Group 1 was given with PTME dose of 20mg/100 g bw for 7 days, Group 2 for 14 days, Group 3 for 30 days, Group 4 for 40 days and Group 5 taken as an Alloxan control. Animals were sacrificed at their respective time along with the normal rats. DPP-IV activity in liver homogenates were done through the kit based on fluorescence ELISA. After treatment with PTME (20 mg/100 g bw) at different time intervals, the alloxan induced stress enhanced DPP-IV activity in liver significantly decreased in a time dependent mannerin. This short study provides an idea, how PTME protects liver via its potential role as DPP-IV inhibitor. But it needs further deep study to reveal the overall mechanism at pathological, clinical and molecular basis in different models of liver diseases.

Authors: Koc A.  Bulent Koc , Liu Bo
Published: April 2018

Abstract.

Ultrasound-assisted cutting has been used to cut materials with high precision, improved quality and reduced cutting forces. The research objective was to investigate the effects of high-frequency vibrations on the cutting force and cutting energy of switchgrass and miscanthus stems. Laboratory experiments were conducted on individual biomass stems at cutting speeds between 3 and 400 mm/s. An experimental cutting system with an ultrasound generator, an ultrasonic blade, a load cell, and a data acquisition system was developed. The custom designed blade was 5-cm wide and vibrated at 19.551 kHz with 2.8 µm tip vibration amplitude. There were significant measured differences in the cutting forces and cutting energies between conventional cutting and ultrasonic cutting of switchgrass and miscanthus stems (p < 0.05). These results suggest that the use of high-frequency vibrations reduce cutting force and cutting energy of both switchgrass and miscanthus stems. Ultrasound-assisted cutting reduced the cutting energy of switchgrass by 66.85% at 100 mm/s and miscanthus by 80.58% at 30 mm/s. However, ultrasonic cutting did not have a significant effect on the cutting force and cutting energy when the cutting speed was equal to or greater than the blade tip vibration speed. The results of this research should be useful for adapting the ultrasonic technology in biomass harvesting, particle size reduction, and processing equipment.

Published: April 2018

Abstract.

Mixing fans (MFFs) are widely used in ventilation of agricultural buildings to improve the uniformity of the air supply, thereby improving the ventilation efficiency. In order to improve the ventilation performance of MFFs, a new visor-shaped diffuser was designed and installed on a MFF. The angle and the length of the diffuser were crucial parameters that affected the performance of the MFFs with the diffusers. Thereby, in this study numerical simulation with 42 diffusers of different angles (ranged from 90-270°) and different lengths (ranged from 150-650 mm) with the MFF were studied with Computational Fluid Dynamics (CFD) simulation to acquire the optimal design of diffusers. The numerical simulation results show that the diffusers of 90°/450 mm, 120°/350 mm, and 150°/250 mm with jet lengths of up to 5.85, 5.90, and 5.85 m, respectively, had better performances among all the diffusers. The optimal prototype diffusers of 90°/450 mm, 120°/350 mm, and 150°/250 mm of MFFs were tested by laboratory study and field test. The test was conducted in wind speed distributions at distances of 0.5 to 1.0 m from the axial of MFFs. During the test, we evaluated the MFFs performance such as maximum flow flux, maximum energy efficiency, and non-uniformity coefficient. The diffuser of 150°/250 mm showed the best performance, increasing the flow flux and energy efficiency by 3.8% and 11%, respectively, and obtain higher axial wind speeds and larger non-uniformity coefficients. Finally, the diffusers of 150°/250 mm were tested in a free-stall dairy barn. The field test result shows that the diffusers of 150°/250 mm increased overall average wind speeds by 7.4% and local average wind speeds at bedding 1 and bedding 2 by 31.0% and 27.7%, respectively, which agreed with our numerical simulation and laboratory test. This optimal design of mixing fans could be applied to improve the air mixing in agricultural buildings. Keywords: Agricultural buildings, Diffuser, Mixing fan, Numerical simulation, Optimization.

Published: April 2018

Abstract. Northeastern North America is the world’s leading producer of wild blueberry. Ripening of wild blueberry is the leading factor for fruit quality. Currently, there are no protocols available for the farming community related to wild blueberry fruit ripening and maturity. A nondestructive, rapid, and reliable digital photography technique could be used to examine the ripening of wild blueberries for appropriate harvesting time. Two wild blueberry fields were selected to examine the berry ripening levels using digital photographic techniques at different time of harvest (early, middle, and late seasons). The fields were divided into four blocks and each block was further divided into three classes of times of harvest. Fruit images from each block were acquired and processed to count blue pixels from each image. A significant correlation was found between percentage of blue pixels and actual fruit yield in Field A (R2 = 0.96; P < 0.001) and Field B (R2 = 0.97; P < 0.001). The results also indicated that the effect of time of harvest on fruit yield was significant and fruit yield increased gradually during early harvesting, reached maximum during mid-season, and then started to decrease in late harvesting. Results indicated that 90% of green-berries had turned blue at the end of middle season compared to early season (58%). Based on the results of this study, optical analysis could help to keep fruit quality by optimizing appropriate harvesting time of wild blueberries. It is also suggested that the optimum time to harvest wild blueberries is middle season to ensure high fruit yield and quality. Keywords: Blue pixels, Fruit yield, Harvesting season, Wild blueberry.

Authors: Ahn Jun-Bae
Published: April 2018

To determine the bioactive compound of domestic cherry tomato, the levels of lycopene, β-carotene, and phenolic compounds were analyzed in three domestic cherry tomato cultivars (Summerking, Qutiquti, and Minchal) using HPLC and LC-MS/MS. The levels of lycopene were 69.40 mg/100 g (Qutiquti), 69.07 mg/100 g (Minichal), and 38.52 mg/100 g (Summerking). The contents of β-carotene were 3.35 mg/100 g (Qutiquti), 2.30 mg/100 g (Summerking), and 2.25 mg/100 g (Minichal). Five phenolic compounds were identified exactly as 3-caffeoylquinic acid, 5-caffeoylquinic acid, quercetin-3-apiosylrutinoside, quercetin-3-rutinoside, and naringenin chalcone from three domestic cherry tomatoes. Five phenolic compounds were identified partially as two isomers of caffeic acid-hexose, caffeoylquinic acid isomer, di-caffeoylquinic acid, and tri-caffeoylquinic acid from three domestic cherry tomatoes. Naringenin chalcone was the most abundant phenolic compound, ranging from 78.2 mg/100 g for Qutiquti to 222.9 mg/100 g for Summerking. High levels of quercetin-3-rutinoside and 5-caffeoylquinic acid were found, ranging 24.3- 50.8 mg/100 g and 31.8-47.6 mg/100 g, respectively. These results suggested that domestic cherry tomatoes can be used as bioactive food materials.

This article discusses Christianization in Bali during the late XIX until XX century that was not only become religious phenomena, but also the pragmatical of government policy. It is compiled with historical method. According to the study, it can be delivered that Bali in the Dutch colonial era was in a tense situation. It was not only because the new religion came from the other parts of the world and therefore considered as alien by the local community based on Hinduism, but also discrimination against the zending institution conducted by the colonial regime. In the macro policy level, the government put into zending and mission became counterpart as well as media to conquer and civilize the colonies in order to face of Islamic radicalism as a common enemy. However, the government viewed that Bali as a strategic partner against the common enemy. Christianization was feared to lead a strong rejection from the Balinese people and ultimately led to resistance of the government. Therefore, the government prohibited zending in Bali despite the reasons that were not commonly found in the dominant politics of cultural preservation.

Relational Missiology. When Mission Gets In Between
Authors: Vellguth Klaus
Published: April 2018

The addressees of the mission of the Church today cannot be defined in terms of territorial. As a result of numerous theological discussions, an interesting expression emerged that reflected the dynamics of the mission – missio inter gentes. The preposition communicating inter indicates a specific relationship between the mission of the Church and its addressees. Missiology, which examines the nature of the mission focuses on its relatedness and hence becomes an advocate a relational theology also relational understanding of faith, religion, ecclesiology and dialogue because God gets in between.
Summability on non-rectifiable Jordan curves
Authors: Guseynov Yevgeniy
Published: April 2018

For a given parameterization of a Jordan curve, we define the notion of summability or classes of measurable functions on a contour where a new integral is introduced.
It is shown that natural functional spaces defining summability for non-rectifiable Jordan curves are the Lebesgue spaces with the weighted norm.
For non-rectifiable Jordan curves where an integral was previously defined for continuous (Hölder) functions [Y. Guseynov,
Integrable boundaries and fractals for Hölder classes; the Gauss–Green theorem,
Calc. Var. Partial Differential Equations 55 2016, 4, Article ID 103], a weight function is constructed which, in general, is not summable by parameter, and a weighted functional space (summability) is defined where the new integral exists.
Quality of life and reconstructive surgery efforts in severe hand injuries
Authors: Alawi Seyed Arash , Werner Dennis , Könneker Sören , Vogt Peter M. , Jokuszies Andreas
Published: April 2018

Introduction:

Severe hand trauma, leading to extensive skeletal and tissue defects, requires plastic surgical reconstruction of the highest level aiming at maximizing function and aesthetics. The intention of this study was to investigate clinical parameters and resource consumption connected with severe hand injuries, with specific emphasis on a follow-up evaluation of quality of life after the reconstruction process.

Materials and methods:

In this retrospective study, we evaluated patients with severe hand injuries from 2013 to 2016 who had completed surgical and non-surgical treatment. Measures included total period of therapy (TPT) in days, total duration of operations including anesthesia (TOA), total duration of all operations (TO), and total number of operations (TNO). We also determined total inpatient stay (TIS), total number of clinic presentations with interventions (TNPI), initial hand injury severity score (iHISS), and inpatient proceeds (IPP) in Euros (€). Correlation was assessed between iHISS and TOA, TNO, and TIS. Finally, these patients were reexamined in a follow-up inquiry and the life quality was assessed with the five-level version of the EuroQol five-dimensional (EQ-5D) descriptive system (EQ-5D-5L).

Results:

We analyzed 12 patients with an average age of 44 years (min. 24 years, max. 75 years). Patients receiving reconstructive surgery experienced median (${\rm{\tilde x}}$) TPT of 175 days [interquartile range (IQR), 51–499], TOA of 13 h (IQR, 6–37), TO of 9 h (IQR, 4–25), and TNO of 5 (IQR, 3–11). Further, the patients’ median TIS was 22 days (IQR, 9–86), TNPI was 4 (IQR, 2–8), and iHISS was 77 (IQR, 44–162). The median IPP was 14.595 € (IQR, 5.541–33.709 €). IHISS was positively correlated with Pearson’s r for TIS (0.817), TOA (0.857), and TNO (0.871). The EQ-5D-5L index value resulted in a high level of life quality with a median of 0.898 (min. 0.8, max. 1).

Conclusion:

Severe hand injuries are related to high efforts for surgical and functional reconstructions, which result in high quality of life measured with the EQ-5D-5L assessment. However, for a defined collective of patients, myoelectric prosthetic functional replacement should be considered. Further studies are necessary to examine functional outcomes and quality of life after bionic prosthetic replacement. Also, a bionic reconstruction score to define hard criteria for taking an acute treatment decision is necessary.

Cerebral toxoplasmosis in a diffuse large B cell lymphoma patient
Authors: Savsek Lina , Opaskar Tanja Ros
Published: April 2018

Background

Toxoplasmosis is an opportunistic protozoal infection that has, until now, probably been an underestimated cause of encephalitis in patients with hematological malignancies, independent of stem cell or bone marrow transplant. T and B cell depleting regimens are probably an important risk factor for reactivation of a latent toxoplasma infection in these patients.

Case report

We describe a 62-year-old HIV-negative right-handed Caucasian female with systemic diffuse large B cell lymphoma who presented with sudden onset of high fever, headache, altered mental status, ataxia and findings of pancytopenia, a few days after receiving her final, 8th cycle of rituximab, cyclophosphamide, vincristine, doxorubicin, prednisolone (R-CHOP) chemotherapy regimen. A progression of lymphoma to the central nervous system was suspected. MRI of the head revealed multiple on T2 and fluid attenuated inversion recovery (FLAIR) hyperintense parenchymal lesions with mild surrounding edema, located in both cerebral and cerebellar hemispheres that demonstrated moderate gadolinium enhancement. The polymerase chain reaction on cerebrospinal fluid (CSF PCR) was positive for Toxoplasma gondii. The patient was diagnosed with toxoplasmic encephalitis and successfully treated with sulfadiazine, pyrimethamine and folic acid. Due to the need for maintenance therapy with rituximab for lymphoma remission, the patient now continues with secondary prophylaxis of toxoplasmosis.

Conclusions

With this case report, we wish to emphasize the need to consider cerebral toxoplasmosis in patients with hematological malignancies on immunosuppressive therapy when presenting with new neurologic deficits. In such patients, there are numerous differential diagnoses for cerebral toxoplasmosis, and the CNS lymphoma is the most difficult among all to distinguish it from. If left untreated, cerebral toxoplasmosis has a high mortality rate; therefore early recognition and treatment are of essential importance.
Imaging of human glioblastoma cells and their interactions with mesenchymal stem cells in the zebrafish (Danio rerio) embryonic brain

Published: April 2018

Background

An attractive approach in the study of human cancers is the use of transparent zebrafish (Danio rerio) embryos, which enable the visualization of cancer progression in a living animal.

Materials and methods

We implanted mixtures of fluorescently labeled glioblastoma (GBM) cells and bonemarrow-derived mesenchymal stem cells (MSCs) into zebrafish embryos to study the cellular pathways of their invasion and the interactions between these cells in vivo.

Results

By developing and applying a carbocyanine-dye-compatible clearing protocol for observation of cells in deep tissues, we showed that U87 and U373 GBM cells rapidly aggregated into tumor masses in the ventricles and midbrain hemispheres of the zebrafish embryo brain, and invaded the central nervous system, often using the ventricular system and the central canal of the spinal cord. However, the GBM cells did not leave the central nervous system. With co-injection of differentially labeled cultured GBM cells and MSCs, the implanted cells formed mixed tumor masses in the brain. We observed tight associations between GBM cells and MSCs, and possible cell-fusion events. GBM cells and MSCs used similar invasion routes in the central nervous system.

Conclusions

This simple model can be used to study the molecular pathways of cellular processes in GBM cell invasion, and their interactions with various types of stromal cells in double or triple cell co-cultures, to design anti-GBM cell therapies that use MSCs as vectors.
18F-FET and 18F-FCH uptake in human glioblastoma T98G cell lines
Authors: Persico Marco Giovanni , Buroni Federica Eleonora , Pasi Francesca , Lodola Lorenzo , Aprile Carlo , Nano Rosanna , Hodolic Marina
Published: April 2018

Background

Despite complex treatment of surgery, radiotherapy and chemotherapy, high grade gliomas often recur. Differentiation between post-treatment changes and recurrence is difficult. 18F-methyl-choline (18F-FCH) is frequently used in staging and detection of recurrent prostate cancer disease as well as some brain tumours; however accumulation in inflammatory tissue limits its specificity. The 18F-ethyl-tyrosine (18F-FET) shows a specific uptake in malignant cells, resulting from increased expression of amino acid transporters or diffusing through the disrupted blood-brain barrier. 18F-FET exhibits lower uptake in machrophages and other inflammatory cells. Aim of this study was to evaluate 18F-FCH and 18F-FET uptake by human glioblastoma T98G cells.

Material and methods

Human glioblastoma T98G or human dermal fibroblasts cells, seeded at a density to obtain 2 × 105 cells per flask when radioactive tracers were administered, grew adherent to the plastic surface at 37°C in 5% CO2 in complete medium. Equimolar amounts of radiopharmaceuticals were added to cells for different incubation times (20 to 120 minutes) for 18F-FCH and 18F-FET respectively. The cellular radiotracer uptake was determined with a gamma counter. All experiments were carried out in duplicate and repeated three times. The uptake measurements are expressed as the percentage of the administered dose of tracer per 2 × 105 cells. Data (expressed as mean values of % uptake of radiopharmaceuticals) were compared using parametric or non-parametric tests as appropriate. Differences were regarded as statistically significant when p<0.05.

Results

A significant uptake of 18F-FCH was seen in T98G cells at 60, 90 and 120 minutes. The percentage uptake of 18F-FET in comparison to 18F-FCH was lower by a factor of more than 3, with different kinetic curves.18F-FET showed a more rapid initial uptake up to 40 minutes and 18F-FCH showed a progressive rise reaching a maximum after 90 minutes.

Conclusions

18F-FCH and 18F-FET are candidates for neuro-oncological PET imaging. 18F-FET could be the most useful oncological PET marker in the presence of reparative changes after therapy, where the higher affinity of 18F-FCH to inflammatory cells makes it more difficult to discriminate between tumour persistence and non-neoplastic changes. Additional studies on the influence of inflammatory tissue and radionecrotic cellular components on radiopharmaceutical uptake are necessary.
EJE PRIZE 2018: A gut feeling about glucagon
Authors: Knop Filip K
Published: April 2018

Hyperglucagonaemia (in the fasting as well as in the postprandial state) is considered a core pathophysiological component of diabetes and is found to contribute substantially to the hyperglycaemic state of diabetes. Hyperglucagonaemia is usually viewed upon as a consequence of pancreatic alpha cell insensitivity to the glucagon-suppressive effects of glucose and insulin. Since we observed that the well-known hyperglucagonaemic response to oral glucose in patients with type 2 diabetes is exchanged by normal suppression of plasma glucagon levels following isoglycaemic intravenous glucose administration in these patients, we have been focusing on the gut and gut-derived factors as potential mediators of diabetic hyperglucagonaemia. In a series of clinical experiments, we have elucidated the role of gut-derived factors in diabetic hyperglucagonaemia and shown that glucose-dependent insulinotropic polypeptide promotes hyperglucagonaemia and that glucagon, hitherto considered a pancreas-specific hormone, may also be secreted from extrapancreatic tissues – most likely from proglucagon-producing enteroendocrine cells. Furthermore, our observation that fasting hyperglucagonaemia is unrelated to the diabetic state, but strongly correlates with obesity, liver fat content and circulating amino acids, has made us question the common ‘pancreacentric’ and ‘glucocentric’ understanding of hyperglucagonaemia and led to the hypothesis that steatosis-induced hepatic glucagon resistance (and reduced amino acid turnover) and compensatory glucagon secretion mediated by increased circulating amino acids constitute a complete endocrine feedback system: the liver–alpha cell axis. This article summarises the physiological regulation of glucagon secretion in humans and considers new findings suggesting that the liver and the gut play key roles in determining fasting and postabsorptive circulating glucagon levels.

O texto objetiva apresentar um quadro de pesquisas em História da Educação disseminadas na comunidade acadêmica e produzidas a partir das teorias de Norbert Elias. Os conceitos privilegiados são: figuração, poder, estado e gênio. Tais constructos possibilitaram-nos interpretações sobre a história das instituições escolares como monopólios do Estado, das escolas de formação de professores como figurações de relações de poder e das trajetórias de educadores intelectuais como um entrecruzamento do pedagógico, cultural, político, artístico e social. Os temas abordados recaíram sobre a sociedade brasileira do século XIX e início do XX.
Las paradojas del heroísmo y de la civilización en Ignacio Manuel Altamirano
Authors: López Horacio González , Sánchez Irene Marquina
Published: April 2018

Este escrito busca develar la postura sostenida por el multifacético escritor mexicano Ignacio Manuel Altamirano, respecto de dos conceptos esenciales a los cambios socio-políticos enfrentados por el México de la segunda mitad del siglo XIX: por un lado el concepto de Héroe y, con él, el concepto de Heroísmo, y por otro lado, el concepto de Civilización. Este último concepto es abordado a la luz del trabajo realizado por Norbert Elias acerca de la sociogénesis del concepto de Civilización. Sobre la base de una breve revisión histórica, este escrito señala que, en Francia, a finales del Siglo XVIII, ya se habían advertido algunas contradicciones implicadas en ese concepto. En el anterior sentido, las contradicciones susceptibles de se halladas en el manejo que Altamirano hizo de ese mismo concepto no le eran exclusivas.
Preceitos para bem viver: um estudo sobre manuais de civilidade e etiqueta na década de 1950
Authors: Cunha Maria Teresa Santos , Santos Márcia Regina
Published: April 2018

O período posterior às guerras mundiais demandou a reinvenção das convivências, do sentimento de pertença e das formas de distinção. O presente artigo discutirá as leituras de formação, mais precisamente, manuais de etiqueta e boas maneiras produzidos para contribuirem no processo de reabilitação dos modos compreendidos como civilizados, no sentido de compreender as concepções do que é civilizado em cada tempo, as formas mobilizadas para internalizar os hábitos, os tipos de conteúdos divulgados e quais eram os ensinamentos propostos na literatura sobre boas maneiras.. Como corpo documental foram selecionados dois manuais de boas maneiras produzidos na década de 1950, editados e comercializados no Brasil, intitulados Aprenda boas maneiras, da autora Dora Maria (1958) e Boas maneiras, da autora Carmen D’Ávila (1958). A análise dos documentos sinalizou que a formação proposta nos dois manuais se constrói a partir de lugares diferentes que convergem para uma mesma organização. As considerações elaboradas a partir da discussão com as  propostas por  Norbert Elias  sobre o tema, a abordagem de alguns conteúdos e a análise da materialidade permitiram evidenciar a continuidade dessa demanda por formação e o potencial de alcance das prescrições.
Práticas de escrita de educadoras como experiência formativa na escola
Authors: Pinto Keila Santos , Chaluh Laura Noemi
Published: April 2018

Este trabalho apresenta parte de uma pesquisa de mestrado que buscou compreender a atuação da professora coordenadora, no contexto dos espaços de formação na escola, por meio das práticas de escrita realizadas pelas professoras e professora coordenadora em uma escola municipal de Educação Infantil, localizada no interior do Estado de São Paulo. O percurso investigativo da pesquisa pautou-se na narrativa de experiências do vivido (LIMA, GERALDI E GERALDI, 2015), e os dados foram analisados a partir do paradigma indiciário de Ginzburg (1989). Enquanto professora coordenadora, ao pesquisar sua própria prática, a intenção foi mobilizar uma experiência formativa, a qual ampliasse a interlocução entre as educadoras, exercício esse que disparou a reflexão sobre as potencialidades e as limitações das práticas formativas existentes na escola, ao legitimar a escola como espaço-tempo de produção de sentidos e conhecimentos. Uma das propostas dessa interlocução foi o Diário de HTPC (Horas de Trabalho Pedagógico Coletivo), uma ação coletiva de escrita que possibilitou propor diferentes formas de organização desse espaço de formação, ao promover o movimento das palavras, a liberdade de dizer sobre si e sobre o outro, o estreitamento das relações de intimidade e confiança e o compartilhamento dos sentimentos e saberes.
A cidade e os museus: cognição e tecnologias em questão
Authors: Carvalho Cristina
Published: April 2018

O presente artigo aborda aspectos relacionados aos espaços não formais de educação, na perspectiva da cidade educadora, e o potencial dos museus no uso de tecnologias digitais para ampliar experiências educativas. Nessa perspectiva, são então analisadas algumas experiências que vêm sendo desenvolvidas nessa área e que incorporam a cidade como ambiente de educação e memória coletiva de uma comunidade, a partir dos artefatos nos quais a memória é incorporada e interpretada. Constata-se que o uso de ambientes virtuais e de tecnologias digitais tem se apresentado de modo cada vez mais recorrente em museus, modificando experiências corporais e culturais, e expandindo os espaços de aprendizagem.
Direito Fundamental a uma nacionalidade
Authors: Cavallieri Leila Arruda
Published: April 2018

Os direitos fundamentais são a base da garantia do exercício pleno da dignidade humana.A salvaguarda desses direitos pelo país é um dever que não pode ser relegado ou olvidado. Desta forma, existem mecanismos que compelem o Estado a proteger, defender e cobrar respeito pelos mesmospor parte da sociedade e de outros Estados. No caso da adoção internacional, o direito à convivência familiar é conquistado pelos adotandos a partir da sentença judicial brasileira. Porém, ao se tornarem filhos de pais domiciliados em outro Estado, as crianças e adolescentes aqui nascidos precisam ter as garantias que são atinentes ao status de cidadão daquele país. A partir do reconhecimento do direito à nacionalidade pelo país de acolhida das crianças, elas passam a usufruir de uma condição de equiparação a seus adotantes, do ponto de vista de direitos e deveres. A nacionalidade ou cidadania para os adotandos é um direito fundamental que necessita ser conquistado e preservado, através das normativas internas ou de direito convencional, visando atender ao superior interesse da criança ou adolescente. A legislação italiana é uma das legislações estrangeiras que possui tais dispositivos, o que se torna uma grande conquista no direito transnacional. PALAVRAS-CHAVE: direitos fundamentais; adoção internacional; direito à convivência familiar; direito à nacionalidade   Abstract Fundamental rights are the basis for ensuring the full exercise of human dignity. The safeguarding of these rights by the country is a duty that can not be relegated or forgotten. Thus, there are mechanisms that compel the State to protect, defend and claim respect for them by society and other States. In the case of international adoption, the right to family coexistence is won by adoptees based on the Brazilian judicial decision. However, when they become children of parents domiciled in another State, the children and adolescents here born need to have the guarantees that are pertinent to the status of citizen of that country. From the recognition of the right to nationality by the host country of the children, they will enjoy a condition of equality with their adopters, from the point of view of rights and duties. Nationality or citizenship for adopte is a fundamental right that needs to be won and preserved, through internal norms or conventional law, in order to meet the superior interest of the child or adolescent. The Italian legislation is one of the foreign laws that have such devices, which becomes a great achievement in transnational law. KEYWORDS: fundamental rights; international adoption; right to family life; right to nationality

Published: April 2018

O objetivo deste trabalho foi realizar uma revisão integrativa sobre quais os principais fatores associados aos índices de desperdício em Unidades de Alimentação e Nutrição. Por meio dos descritores “alimentação coletiva”, “desperdício” e “unidades de alimentação e nutrição”, foram realizadas buscas em bases de dados eletrônicas (LILACS, MEDLINE, Scielo e Google Acadêmico), selecionando-se artigos completos que abordassem a temática desperdício em unidades de alimentação e nutrição, nos idiomas português e inglês, publicados entre os anos de 2008 e 2016. Conforme resultados encontrados pela literatura, os principais fatores que contribuem para os elevados percentuais de desperdício em Unidades de Alimentação e Nutrição são os elevados níveis de resto-ingesta devido à falta de orientações aos comensais, falta de treinamento dos manipuladores, falhas durante o armazenamento e o pré-preparo, elevados fatores de correção, falhas durante planejamento e recebimento de matéria-prima e a falta de padronização na elaboração das preparações. Dessa forma, verifica-se a importância de um bom planejamento, monitoramento e treinamento de funcionários durante todas as etapas de recebimento, produção, armazenamento distribuição. Assim como, a conscientização dos comensais em relação à redução dos níveis de desperdício por meio de palestras, cartazes e materiais impressos.

Authors: BYBORDI Ahmad , GHEIBI Mohammad Nabi
Published: April 2018

Both the beneficial and the adverse effects of various nickel level supplements on growth and chlorophyll content of canola plants were evaluated while either urea or ammonium nitrate was supplied as the sole N source in the nutrient solutions. This study was arranged in completely randomized with three replications. Treatments included nutrient solution cultures containing urea and ammonium nitrate at the rate of 84 mg N L-1 separately as nitrogen sources with four nickel levels as NiSO4.6H2O at the rates of 0, 0.01, 0.05 and 0.1 mg Ni L-1. Plants were allowed to grow for 6 weeks then leaves chlorophyll content and shoots and roots fresh and dry weight were determined. Both plant growth and leaves chlorophyll content of the urea-fed plants increased significantly with the increase in nickel content up to 0.1 mg Ni L-1. However, root fresh and dry weight increased up to 0.01 mg Ni L-1 and started to decrease with further increase in solutions nickel content. Nickel did not affect these parameters with plants supplied with ammonium nitrate significantly. In these plants, the optimum nickel level for shoot growth and leaves chlorophyll content was 0.05 mg L-1 and for root fresh and dry weight was 0.01 mg Ni L-1. Further increase in Ni concentration reduced growth. As a whole, plants received urea plus nickel performed better than those received ammonium nitrate plus nickel.

The soil seedbank of Tithonia diversifolia, an invasive species which dominates open waste fallowland vegetation was studied. Two different roadside sites which vary in extent of open waste land were selected.The species composition of the established vegetation was assessed in the two diferent sites. Twenty top soil samples were collected at five different distances (15 cm, 30 cm, 45 cm, 60 cm, and 75 cm) inwards away from each main road in dry and rainy seasons and the seed bank composition was determined by greenhouse germination over a 6 month period. The similarity between the composition of the seed bank flora and that of the established vegetation was low. The least and the highest emerged seedlings density was recorded in the 15 metres and 75 metres respectively inwards away from the main road in both seasons. The results of the seedlings emergence is a reflection of the extent of open waste land dominated by the invasive species due to human disturbance (road construction) on both sites. Overall results suggest that the emergence of the species from the soil seed bank may be due to the impact of the invasive species Tithonia diversifolia on other plant species in the study environment.

Published: April 2018

Garlic is one of the oldest and popular spices in the World that also contain very good nutritional value. Garlic has a wide spectrum of actions not only is it antibacterial, antiviral, antifungal and antiprotozoan but it also has beneficial effects on the cardiovascular and immune systems. They contain unique oil which is very easily digested and is stable to oxidative stress and for this reasons they are useful and healthy for consumption. Several epidemiological and experimental studies suggest that garlic oil has been thought to bring about its anticarcinogenic effect and other pharmacological properties through a number of mechanisms, such as the scavenging of radicals, increasing glutathione levels, increasing the activities of enzymes such as glutathione S transferase, catalase, incubation of cytochrome p450 2E1, DNA repair mechanisms, prevention of chromosomal damage etc. Future research should standardize the dosage of garlic and type. Several hypotheses suggest that the anticancer mechanism may be due to DNA repair mechanism, prevention of chromosomal damage, antiproliferative effect and alteration of the cell cycle. Garlic and garlic oil should be considered as one of the most valuable food for good quality of life in general.

Published: April 2018

Viral diseases are a major threat to world agriculture and breeding resistant varieties against these viruses is one of the major challenge faced by plant virologists and biotechnologists. The development of the concept of pathogen derived resistance gave rise to strategies ranging from coat protein based interference of virus propagation to RNA mediated virus gene silencing. Much progress has been achieved in protecting plants against these RNA and DNA viruses. In this review, the most recent transgene based approaches for viral disease management in plants will be discussed.

Published: April 2018

Salinity, either of soil or of irrigation water, causes disturbances in plant growth and nutrient balance. Previous work indicates that applying nutrients by foliar application increases tolerance to salinity. A pot experiment with three replicates was carried out in the green house of NRC, Cairo, Egypt, to study the effect of micronutrients foliar application on salt tolerance of faba bean. Two concentrations of a micronutrient compound (0.1% and 0.15%) were sprayed in two different treatments prior to or after the salinity treatments. Levels of NaCl (0.00-1000-2000-5000 ppm) were supplied to irrigation water. Results indicated that 2000 and 5000 ppm NaCl inhibited growth and nutrient uptake. Spraying micronutrients could restore the negative effect of salinity on dry weight and nutrients uptake, when sprayed either before or after the salinity treatments. It is suggested that micronutrient foliar sprays could be used to improve plant tolerance to salinity.

Tropical moist climate in Manipur supports rich and luxuriant growth of Bambusa tulda Roxb. locally known as Saneibi, which is endemic to northeastern region and West Bengal of India. It represents one of the most costly species of bamboo in Manipur, its price ranging from Rs. 70-150/-per mature bamboo culm. The meitei Manipuris have a rich traditional knowledge for utilization of this particular bamboo species. In fact, it has got multipurpose use covering several aspects from religious to industrial. Because of its strength and durability it is of great demand on the market. Its young shoots (ushoi) and the fermented young shoots (soibum) represent a significant vegetable for local people. Ushoi costs Rs.10-50/- per piece while soibum cost Rs. 30-50/- per kg. Local medicine man use this for healing properties. It forms a good raw material for various handicraft works, house building, paper industries, fencing, and several other useful equipments for day to day life. This bamboo species could yield more than 15 very commonly used and highly marketable articles with prices ranging from Rs.10/-to Rs 300/-per piece. Therefore, the development of small scale industries with highly skilled handicraftsmen can be profitable. Plantation of this bamboo species on farmland, borders of home garden, foothills, riversides, sides of ponds will prove to be a good business as well as a proper help in the conservation and sustainable management of this endemic species. Traditional mode of propagation is done successfully through off-set planting method. This paper presents a detailed study on this particular bamboo species regarding taxonomy, status of distribution, density, regeneration capacity, traditional uses, methods of processing and its commercial implications highlighting the eco-friendly nature of bamboo plantation and bamboo products.

This study examined the allelopathic effect of Ludwigia decurrens and L. adscendens exudates on germination, seedling growth (hypocotyl and radicle elongation), seedling mortality, vegetative growth and reproductive yield of Corchorus olitorious. Ludwigia decurrens, L. adscedens exudates and tap water (control) were applied to seeds of Corchorus olitorious over a period of 15 days and to 3 weeks old seedling for a period of 4 weeks. Ludwigia exudates had no inhibitory effect on the germination percentage of C. olitorious, but the exudates from the two Ludwigia spp. induced mortality rate of the 15 day old seedlings (control: 5.00%, L. decurrens: 17.50%, L. adscendens: 26.88%) and a significant decrease in seedling elongation (hypocotyl and radicle length) of C. olitorious. For the vegetative growth experiment, results showed that the stem length, stem fresh weight and leaf area of C. olitorious were significantly inhibited during week 6 (P
