Authors: Soria Carlos A 
Published: October 2017

Se estudió el efecto del Bioterr Labitech, un nuevo fitonematicida a base de benzimidazol, como una alternativa al uso de nematicidasorganofosforados y clorinados. Se utilizaron varios cultivos comerciales para demostrar, primero, la incidencia de diferentes géneros denematoparásitos en dichas plantaciones, y segundo, el control de los mismos utilizando diferentes dosificaciones, únicas o repetitivas,del producto. No se reportó fitotoxicidad en banano (Musaparadisiaca), tomate de árbol(Solanum betaseum), rosas(Rosasp.) y tomate riñón(Solanum lycopersicum), inclusive utilizando dosis por encima de las recomendadas. En los suelos de los rosales estudiados, se encontró principalmente Meloidogyne, Paratylenchusy Pratylenchus, como los más numerosos. El Bioterr redujo el número de nemátodos del suelo en rosas y tomate de árbol a niveles considerados fitopatológicamente tolerables. También hubo disminución parasitaria en las agallas radiculares causadas por Meloidogynesp. El control dentro de las agallas parece indicar que el producto actúa, no solamente por contacto externo fuera de la raíz con parásitos libres, sino también en forma sistémica con los endoparásitos. Se reporta diferencias significativas en la sensibilidad parasitaria comparada con los saprófitos que resultan menos afectados. Se anota esta diferencia considerando la importancia de estos últimos en el mantenimiento del equilibrio bioquímico de los suelos.

Introduction: Neonatal sepsis is a serious problem in developing countries like Nepal. The main objectives of this study were to determine the bacteriological profile of neonatal sepsis, to determine the antimicrobial susceptibility patterns of the causative agents and to evaluate the association between the neonatal sepsis and the different characteristics of the neonates.Methods: A hospital based cross-sectional study was conducted among a total of 450 neonates suspected of suffering from sepsis. Blood culture was performed using statdard microbiological techniques. The colonies grown were identified on the basis of colony morphology, Gram’s stain and biochemical tests. The antimicrobial susceptiblility testing was performed by Kirby Bauer disc diffusion method. Results: Out of total 450 blood samples, 92 (20.4%) were culture positive. Of which, 16 (17.4%) samples contained gram negative bacteria and 76 (82.6%) samples contained gram positive cocci. The most common bacterial pathogens isolated were Staphylococcus epidermidis (67.4%) followed by Escherichia coli (13%). All gram positive cocci were susceptible to vancomycin, while all gram negative bacilli were sensitive to amikacin. There was statistically significant relationship between neonatal sepsis and gestation age of neonates.Conclusions: Neonatal sepsis is still present as a serious problem in Nepal. Staphylococcus epidermidis was the most common cause of the neonatal sepsis. Prematurely delivered neonates should be given more care, as they are more prone to suffering from neonatal sepsis. Vancomycin and amikacin can be used as the drugs of choice for preliminary treatment of neonatal sepsis in our settings.

<p class="Abstract">The aim of this study was to investigate the hypoglycemic effect of Camellia chrysantha using type 2 diabetic mice model. The ethyl acetate/dichloromethane extract exhibited the most effective hypoglycemic effect. Compared to model group, all the three groups of C. chrysantha extracts significantly improved the mices behavioral performance, weight, reduced water and food intake. The ethyl acetate/dichloromethane extract of C. chrysantha significantly reduced the blood glucose level in the first week after administration and the crude extract also showed a significant effect after longer time administration. All the three extracts reduced the fasting blood glucose level to a certain extent and ethyl acetate/dichloromethane extract exhibited most significant effect among all the three extracts.</p><p><strong>Video Clip of Methodology</strong>:</p><p>1 min 31 sec <a href="https://www.youtube.com/v/X_H_vaA7MgE">Full Screen</a> <a href="https://www.youtube.com/watch?v=X_H_vaA7MgE">Alternate</a></p>
Comparison of Shear Bond Strengths of Conventional Resin Cement and Self-adhesive Resin Cement bonded to Lithium Disilicate: An in vitro Study

Published: October 2017

ABSTRACT

Aim
The aim of this study is to compare the shear bond strengths of conventional resin cement and self-adhesive resin cement bonded to lithium disilicate.

Materials and methods
A total of 40 extracted human molar teeth were mounted in self-cure acrylic resin. Teeth were prepared to obtain flat occlusal surface. About 40 lithium disilicate specimens of dimension—10 mm in diameter and thickness of 2 mm—were fabricated using lost wax technique. The samples were divided into four groups: Groups I, II, III, and IV (n = 10). The specimens were surface treated with Monobond S silane coupling agent. Self-etching primer and bonding agent were applied on the bonding surface of the teeth in groups I and III. The specimens were bonded to the primed teeth with the Multilink N resin cement and subjected to the universal testing machine. The specimens were light-cured. Specimens in groups II and IV were luted to teeth using self-adhesive cement RelyX U100. The same force was applied over the specimen as mentioned above. Excess cement was removed, and light curing was done. The specimens in groups III and IV were subjected to thermocycling for 10,000 cycles at temperatures altering between 5°C and 55°C.

Results
The shear bond strengths of conventional resin cement and self-adhesive resin cement with lithium disilicate were tested before and after thermocycling. Results indicated thermocycling has no significant effect on the bond strengths of conventional or self-adhesive resin cement. However, from the study, it is seen that conventional resin cement had a higher shear bond strength value than the self-adhesive resin cement.

Conclusion
There was a significant difference between the average shear bond strength values of conventional resin cement (Multilink N) and self-adhesive resin cement (RelyX U100) when bonded to lithium disilicate disks, and thermocycling had no significant effect on the bond strength of conventional or self-adhesive resin cements.

Clinical significance
Among all-ceramic systems available, lithium disilicate materials have emerged as an excellent esthetic material for fabrication of anterior and posterior crowns and three-unit anterior fixed partial dentures because of their high translucency and improved optical properties. For successful clinical outcomes, the luting agent should have high bond strength not only to the ceramic surface, but also to the tooth surface.

Published: October 2017

ABSTRACTBackgroundOrthodontic treatment is one of the commonly used dental treatments. Orthodontic forces act on the bone by modulating the biomolecules, chiefly the osteoprotegerin (OPG), osteopontin (OPN), receptor activator of nuclear factor kappa-B (RANK), and RANK ligand (RANKL) (OPG ligand). Hormonal changes are known to cause marked alteration in the levels of these biomolecules. Hence, we planned this study to evaluate the response of bone biomarkers in the gingival crevicular fluid (GCF) in postmenopausal women undergoing fixed orthodontic therapy.Materials and methodsThis study included assessment of 50 subjects who underwent orthodontic treatment from June 2012 to July 2016. All the patients were divided into two study groups with 25 patients in each group: premenopausal group and postmenopausal group. Similar orthodontic wires were used for controlling the forces applied in subjects of both the study groups and their GCF levels of RANKL, and OPN was assessed at baseline and 24 hours after the activation of orthodontic forces. All the results were compiled, assessed, and analyzed by Statistical Package for the Social Sciences software version 16.0. Chi-square test, Student's t-test, and Mann–Whitney U test were used for the assessment of the level of significance.ResultsThe mean values of RANKL and OPN in the premenopausal and postmenopausal groups were found to be 241.52 and 317.15 pg/µL respectively. The mean values of RANKL at baseline in the premenopausal and postmenopausal groups were found to be 7.15 and 3.84 pg/µL respectively. Nonsignificant results were obtained while comparing mean OPN and RANKL level alteration in between the two study groups.ConclusionThe mean alterations in the GCF levels of bone biomarkers are similar for both premenopausal and postmenopausal women.Clinical significanceFor women with either premenopausal or postmenopausal status, orthodontic treatment appears to be equally safer.How to cite this articleBitra A, Rani BJ, Agarkar SS, Parihar AS, Vynath GP, Grover S.

DIREITOS DE PROPRIEDADE E INSTRUMENTOS ECONÔMICOS DE REGULAÇÃO AMBIENTAL: UMA ANÁLISE DAS ATRIBUIÇÕES IMPLÍCITAS
Authors: Santos Laura Meneghel dos , Porto Antônio José Maristrello , Sampaio Rômulo Silveira da Rocha 
Published: October 2017

Considerando que a sobre-exploração dos recursos naturais está, muitas vezes, associada a falta ou insegurança de direitos de propriedade sobre recursos, bens e serviços que beneficiam a sociedade como um todo, esse trabalho aborda o tratamento dessa problemática pelos instrumentos econômicos de gestão e regulação ambiental. Com base no referencial analítico de Direitos de Propriedade proposto nos trabalhos de Elinor Ostrom, Guido Calabresi e Douglas Melamed, foram analisados três instrumentos econômicos de gestão ambiental (tributação, sistemas de certificados negociáveis e pagamentos por serviços ambientais), assim como uma experiência brasileira de cada um deles
Observamos que ao tentar estabelecer um sistema econômico mais eficiente e sustentável via internalização de externalidade ambientais, os instrumentos econômicos de gestão ambiental engendram uma variedade de formas de atribuição tácitas de direitos de propriedade relativos ao meio ambiente.
Ou seja, para que resultados eficientes (tanto ambientalmente quanto economicamente) possam ser de fato gerados, é essencial que o Direito atue no sentido de garantir a segurança jurídica dessas atribuições, formalizando arranjos institucionais claros e impondo sanções efetivas para aqueles que não forem complacentes com a modelagem jurídica e econômica estabelecida para os instrumentos. Fica claro, portanto, que uma política ambiental eficaz não pode prescindir de um tratamento multidisciplinar que se aproprie das ciências jurídica e econômica.
« Seuls les marxistes aiment le passé » : le tiers-mondisme de Pier Paolo Pasolini dans le genre des appunti
Authors: Caminati Luca , Saglier Viviane 
Published: October 2017

Pasolini conçoit en 1968 un projet de film intitulé Notes pour un poème sur le tiers-monde (Appunti per un poema sul Terzo Mondo), constitué d’une série de courts et de moyens métrages en forme de « notes » mêlant fiction et documentaire. Comme d’autres expérimentations avant-gardistes de l’époque, le genre des appunti que pratique Pasolini se situe à l’intersection de différentes formes filmiques, dont le documentaire ethnographique autoréflexif, le récit de voyage expérimental et l’essai cinématographique. Pour Pasolini, aller tourner dans le tiers-monde représente un moyen d’explorer le projet politique du mouvement des pays non alignés issu de la conférence de Bandung et le désir de l’artiste engagé de trouver dans les luttes de libération un espace de changement politique radical, une révolution da farsi. La forme essayiste, ouverte, des appunti de Pasolini vise précisément à reproduire dans sa propre structure hybride l’ouverture du mouvement révolutionnaire.
Du développement du capitalisme à l’infini plan-séquence : les quatre « utopies » de Porno-Teo-Kolossal
Authors: Paquette Julie 
Published: October 2017

Cet article analyse le traitement d’un film jamais réalisé de Pier Paolo Pasolini, Porno-Teo-Kolossal. Il se propose de montrer que les quatre mondes qu’y traversent les deux protagonistes peuvent être compris comme des variations sur la modalité de l’utopie, à savoir l’utopie, la dystopie, l’uchronie et l’atopie ; les trois premiers moments correspondent à la mise en récit de la conscience d’une Europe en voie d’homologation et en butte aux pouvoirs autoritaires et fascistes, alors que le quatrième moment correspond à ce que Pasolini entrevoyait comme une potentialité venue du Sud. Ce parcours doit être considéré comme étant « révolutionnaire », non pas au sens téléologique du terme, mais plutôt au sens du mot latin revolutio, qui signifie « retour à l’origine ». Cette lecture de Porno-Teo-Kolossal permettra de faire entendre une conception de l’engagement qui serait basée sur un infini plan-séquence irréductible à l’opération du montage-mort.
Disturbing the Peace of “Two Not So Very Different” Countries: James Baldwin and Fritz Raddatz
Authors: Zocco Gianna 
Published: October 2017

When James Baldwin in No Name in the Street discusses the case of Tony Maynard, who had
been imprisoned in Hamburg in 1967, he emphasizes that his efforts to aid his unjustly
imprisoned friend were greatly supported by his German publishing house Rowohlt and, in
particular, by his then-editor Fritz Raddatz (1931–2015). While the passages on Maynard
remain the only instance in Baldwin’s published writings in which Raddatz—praised as a
courageous “anti-Nazi German” and a kindred ally who “knows what it means to be beaten in
prison”—is mentioned directly, the relation between Baldwin and Raddatz has left traces
that cover over fifty years. The African-American writer and Rowohlt’s chief editor got to
know each other around 1963, when Baldwin was first published in Germany. They exchanged
letters between 1965 and 1984, and many of Raddatz’s critical writings from different
periods—the first piece from 1965, the last from 2014—focus of Baldwin’s books. They also
collaborated on various projects—among them a long interview and Baldwin’s review of
Roots—which were all published in the German weekly newspaper Die Zeit, where Raddatz
served as head of the literary and arts sections from 1977 to 1985. Drawing on published
and unpublished writings of both men, this article provides a discussion of the most
significant facets of this under-explored relationship and its literary achievements.
Thereby, it sheds new light on two central questions of recent Baldwin scholarship: first,
the circumstances of production and formation crucial to Baldwin’s writings of the 1970s
and 1980s, and secondly, Baldwin’s international activities, his transcultural
reception and influence.
“Who’s the Nigger Now?”: Rhetoric and Identity in James Baldwin’s Revolution from Within
Authors: Houck Davis W. 
Published: October 2017

Despite the proliferation of interest in James Baldwin across popular culture and the
academy, few, if any, critical studies of his public oratory have been conducted. This is
unfortunate and ironic—unfortunate because Baldwin was a marvelous orator, and ironic in
that his preferred solution to what ailed whites and blacks as the Civil Rights movement
unfolded was thoroughly rhetorical. That is, Baldwin’s racial rhetorical revolution
involved a re-valuing of the historical evidence used to keep blacks enslaved both
mentally and physically across countless generations. Moreover, for Baldwin the act of
naming functions to chain both whites and blacks to a version of American history
psychologically damaging to both. Three speeches that Baldwin delivered in 1963 amid the
crucible of civil rights protest illustrate these claims.

Background:Shorter childhood telomere length (TL) and more rapid TL attrition are widely regarded as manifestations of stress. However, the potential effects of health interventions on child TL are unknown. We hypothesized that a water, sanitation, handwashing (WSH), and nutritional intervention would slow TL attrition during the first two years of life.Methods:In a trial in rural Bangladesh, we randomized geographical clusters of pregnant women into individual water treatment, sanitation, handwashing, nutrition, combined WSH, combined nutrition plus WSH (N + WSH), or control arms. We conducted a substudy enrolling children from the control arm and the N + WSH intervention arm. Participants and outcome assessors were not masked; analyses were masked. Relative TL was measured at 1 and 2 years after intervention, and the change in relative TL was reported. Analysis was intention-to-treat.Results:Between May 2012 and July 2013, in the overall trial, we randomized 720 geographical clusters of 5551 pregnant women to a control or an intervention arm. In this substudy, after 1 year of intervention, we assessed a total of 662 children (341 intervention and 321 control) and 713 children after 2 years of intervention (383 intervention and 330 control). Children in the intervention arm had significantly shorter relative TL compared with controls after 1 year of intervention (difference −163 base pairs (bp), p=0.001). Between years 1 and 2, TL increased in the intervention arm (+76 bp) and decreased in the controls (−23 bp) (p=0.050). After 2 years, there was no difference between the arms (p=0.305).Conclusions:Our unexpected finding of increased telomere attrition during the first year of life in the intervention group suggests that rapid telomere attrition during this critical period could reflect the improved growth in the intervention group, rather than accumulated stress.Funding:Funded by The Bill and Melinda Gates Foundation.Clinical trial number:NCT01590095.

Newman, I., Qian, L., Tamrakar, N., Feng, Y., & Xu, G. (2017). Chemical content of unrecorded distilled alcohol (bai jiu) from rural central China: Analysis and public health risk. The International Journal Of Alcohol And Drug Research, 6(1), 59-67. doi:http://dx.doi.org/10.7895/ijadr.v6i1.236Aims: To test 47 samples of locally distilled unrecorded beverage alcohol (bai jiu) obtained in rural central China.Methods: Alcohol samples purchased from home-based makers or from small village shops were analyzed for ethanol, methanol, acetaldehyde, ethyl acetate, six higher alcohols, arsenic, cadmium, and lead. Results were judged against the standards for these compounds set by the AMPHORA Project.Findings: Ethanol concentrations ranged from 38.7% to 63.7% (mean 50.4%). Methanol and methyl acetate detected in all samples did not exceed the Alcohol Measures for Public Health Research Alliance (AMPHORA) limits. Acetaldehyde was present in all samples, with three samples exceeding the AMPHORA limit by a small amount. Lead was found in 57.4% of the samples with one sample exceeding the AMPHORA limit; cadmium was found in 89.4% of the samples with two exceeding the AMPHORA limit. Arsenic was found in 46.8% of the samples with none exceeding the AMPHORA limit.Conclusions: The three samples that exceeded AMPHORA limits for cadmium or lead are of concern in terms of the potential of long-term exposure for local people who regularly consume locally made bai jiu. The main health concern from bai jiu appears to be the risk associated with high ethanol concentration—the same health concern as for recorded, commercially produced spirits.
