Authors: Giacomasso María , Chaparro María Gabriela , Curtoni Rafael Pedro 
Published: November 2019

En este trabajo se discuten algunas políticas públicas de reivindicaciones indígenas hacia el pueblo rankülche de la provincia de La Pampa, Argentina. El análisis se centra en dos acciones de reconocimiento impulsadas por el gobierno provincial, las cuales permiten plantear un giro en la forma de reivindicación, manifestado en la selección de nuevos espacios para el emplazamiento de monumentos, más céntricos y visibles, y en la evocación de referentes conocidos de la historia indígena. Como parte de estas políticas de reparación hacia el patrimonio cultural indígena, recientemente se han comenzado a promover algunas restituciones territoriales en respuesta a demandas rankülches.
Tertium (non) datur: tres lecciones sobre la ficción según Ricardo Piglia
Authors: Zangara Juan Pablo 
Published: November 2019

En un cuerpo textual que fluctúa entre la narrativa y la reflexión crítica, Ricardo Piglia ha insistido en un conjunto de definiciones sobre la literatura. A partir de un diálogo que enlaza las intervenciones reunidas en Crítica y ficción (su última versión, de 2001) con la conferencia en La Habana “Tres propuestas para el próximo milenio (y cinco dificultades)” (publicada en la revista de Casa de las Américas también en 2001), ensayaremos tres derivas de lectura sobre el concepto de ficción acuñado por el escritor argentino. Examinaremos críticamente la suspensión de lo real y la indeterminación de lo verificable, la contradicción de las narrativas del Estado y los restos de la función utópica.

Las prácticas de violencia sexual en la Salta profunda y los regímenes de (in)visibilidad mediática
Authors: Zurita Inés Patricia 
Published: November 2019

El presente artículo indaga los modos de visibilidad que adquirió la violencia sexual dentro del discurso periodístico a inicios del año 2019 en la provincia de Salta, teniendo en cuenta las huellas de las condiciones de producción de la información que estuvieron atravesadas a nivel local por la declaración de Emergencia Pública en materia de Violencia de Género (Decreto N° 7863) debido a que la provincia encabeza uno de índices de femicidios y violaciones más elevados del país por cantidad de habitantes; mientras que a nivel nacional, hubo una ascendente visibilización de la violencia sexual en la agenda pública en el marco del debate por la aprobación de la Ley de Interrupción Voluntaria del Embarazo, y de las luchas emprendidas por el movimiento de mujeres y feminista que van trazando nuevos parámetros de tolerabilidad social respecto a los diversos tipos y modalidades de la violencia contra las mujeres.
El análisis se centra en las representaciones de un caso de violación en banda contra una adolescente, ocurrido en la localidad de Las Lajitas, que se textualizan en cuatro diarios digitales: El Tribuno de Salta, Nuevo Diario de Salta, Informate Salta y Qué Pasa Salta.
Un polo textil impulsado desde la periferia. Abordajes sobre La Salada a partir de investigaciones en Ciencias Sociales
Authors: Bello Juan Martín 
Published: November 2019

En el presente artículo se realiza una revisión bibliográfica de las investigaciones académicas que abordaron el fenómeno de la feria de La Salada. Para ello se han considerado aquellos trabajos que se focalizaron en este conjunto de ferias, ya fuese como su principal objeto de estudio o como un caso relevante dentro de un abordaje más amplio.
A lo largo de las siguientes páginas se expondrán los orígenes de la feria de La Salada, su relevancia para las ciencias sociales, y los modos en que distintos estudios abordaron el fenómeno. En este proceso, se distinguen dos grandes grupos de trabajos, identificando, por un lado, investigaciones centradas en una distinción antinómica entre lo formal y lo informal, y, por otro, estudios que abordan a estas ferias a partir de su dimensión productiva, esto es, a partir de las relaciones y prácticas sociales que consideran específicas del fenómeno.
En el último apartado, se señalan los aportes de estos trabajos y algunas áreas de vacancia que motivan un abordaje de mayor profundidad, vinculadas con los distintos niveles de regularización formal que presentan los locales, el surgimiento de marcas propias y el acercamiento de nuevos públicos.
Post-Harvest Losses along the Rice Value Chain in Kwara State, Nigeria: An Assessment of Magnitude and Determinants
Authors: Babatunde R. , Omoniwa A. , Aliyu J. 
Published: November 2019

Abstract
Post-harvest losses, particularly along the rice value chain, have been highlighted as a major source of reduction in revenue among the value chain actors. It is therefore imperative that empirical assessment of the magnitude and determinants be investigated, so as to be able to provide a reliable policy stand that can help reduce these losses. Patigi and Edu local government areas were purposively sampled from Kwara state, Nigeria, since they are the major producers of rice in the State. Data were gathered through the use of a questionnaire from 40 rice farmers, 40 rice processors and 40 rice marketers. Descriptive statistics and multiple linear regression model were used to analyze the data. The result showed that the loss was highest for farmers at 41-50 kg (₦14402.40) (1 Naira = 0.002772 U.S. $), 31-40 kg (₦2383.20) for processors and at less than 11 kg (₦398.30) for the marketers. Household size and farm size were significant at 1% in determining post-harvest losses for farmers, while only the household size was significant in determining post-harvest losses for processors. It was thus recommended that efficient milling machine should be introduced, particularly to rural rice processors, such that quality grains can be achieved.

Published: November 2019

Abstract
Corn is one of the most important cereal crop grown in Iran. A complete randomized design with four replications was used to analysis the influence of soil amendment of super absorbent polymer on grain yield and yield components of corn in center of Iran in 2016 and 2017. Treatments with super absorbent polymer were 0 kg/ha (S1), 15 kg/ha (S2), 30 kg/ha (S3), and treatments with fertilizers were 50% (F1), 75% (F2), 100% (F3), which could be combined into nine pots. The influence of super absorbent polymer was significant on spike weight in 2017, above-ground biomass in 2016, one hundred seed weight in 2016, and grain yield in 2017. There was no meaningful influence of super absorbent polymer on spike weight in 2016, above-ground biomass in 2017, 100 seed weight in 2017 and grain yield in 2016. Fertilizer treatments had significant influence on spike weight, above-ground biomass, 100 seed weight, and grain yield in both 2016 and 2017. The interaction between SAP and fertilizers had significant effect on above ground biomass in 2017. In both years, the highest spike weight, above ground biomass, 100 seed weight and grain yield was related to S3 (30 kg/ha), followed by S2 (15 kg/ha) and S1 (0 kg/ha), respectively. 100% application of fertilizer (F3) had obtained the maximum spike weight, above ground biomass, 100 seed weight and grain in both 2016 and 2017. Our data have shown that the applied SAP had a remarkable effect on corn growth and yield under different fertilization treatments, and its application of 30 kg/ha gave the best corn production index.
The Relationship between Chlorophyll Content and Antioxidant Activity of Abies alba and Nepeta pannonica Extracts According to Phenophase and Harvesting Area
Authors: Buhăianu S. , Jităreanu Doina Carmen 
Published: November 2019

Abstract
Abies and Nepeta species are well known for their traditional use in traditional medicine from Bukovina, Romania, and other parts from the world. However, too few studies present the connection between phenophase, chlorophyll content and antioxidant activity of extracts obtained from medicinal plants. Phenophases, like stages from vital cycle of plants, involve seasonal and evolutionary changes, including chlorophyll content of the leaves. With these changes, there are also changes in the oxidative activity of the extracts obtained from the studied plants. The chlorophyll was extracted with acetone, being quantitatively measured using the spectrophotometer. Antioxidant activity was determined by the DPPH method. This method is one from the most popular ways to measure the antioxidant capacity of a substance. The studied species are Abies alba and Nepeta pannonica. Plants were harvested from different locations of Bukovina, from areas of Câmpulung Moldovenesc and Cacica localities, Suceava county, Romania. Chosen phenophases were growing and flowering. The DPPH method implies making some extracts with organic solvents from collected plants, in this case being acetone. Using 2,2-diphenyl-1-picrylhydrazil reactive, there was determined the antioxidant capacity of mentioned extracts. There were observed variations of this depending of phenophase and collecting areas, being closely related to total chlorophyll content. The both species have behaved differently and obtained results can be used to determine the optimal harvest moments of these plants.

Published: November 2019

Abstract
In December of 2018 I published my consolidated findings of a closed-form description of propagated signaling phenomena in the membrane of an axon [1]. Those results demonstrate how intracellular conductance, the thermodynamics of magnetization, and current modulation, function together in generating an action potential in a unified differential equation. At present, I report on a subsequent finding within this model. Namely, evidence of quantized magnetic flux Φ0 in an axon.
The angiotensinogen gene polymorphism, lifestyle factors, associated diseases and gastric areas of inflammatory and preneoplastic lesions in a Romanian sample of patients
Authors: Anciuc Mădălina , Tripon Florin , Crauciuc George-Andrei , Mocan Simona , Negovan Anca 
Published: November 2019

Abstract
The aim of our study was to evaluate the association between variant genotype of angiotensinogen (AGT) c.-58A>C, lifestyle factors and clinical factors and corporeal extension of gastric inflammatory and preneoplastic lesions.

Methods: Our study included 209 subjects who underwent a complete set of gastric biopsies, followed by genotyping. They were included to study inflammatory gastric changes and preneoplastic lesions and were grouped according to the localization of changes.

Results: No significant statistical associations were noticed between AGT c.-58A>C genotypes and the corporeal extension of the inflammation or preneoplastic injury groups. Extending preneoplastic lesions to the gastric body was associated with smoking habits (p=0.01) and additionally, there was a significant association between nicotine consumption and the body extension of preneoplastic lesions (p=0.01). The use of acenocoumarol was frequently associated with the progression of histological lesions to preneoplastic lesions (p=0.01). Compared with the wild-type AA genotype, the combined genotypes AA+CC of AGT c.-58A>C were significantly associated with the progression of inflammatory gastric lesions’ according to the regular ingested doses of nonsteroidal anti-inflammatory drugs (NSAIDs).

Conclusion: The AGT c.-58A>C polymorphism is not associated with extension of the gastric lesions. In accordance with nicotine and alcohol consumption, the acenocoumarol co-treatment and multiple cardiac pathologies are associated with the corporeal progression of these injuries. The age below 70 years and NSAIDs treatment for the patients with heterozygous AC genotype and variant homozygous CC genotype for the mentioned SNP have been associated with the corporeal extension of gastric inflammation.
A chronic hepatitis B patient infected with HBsAg diagnostic-escape strain in the presence of anti-HBs positivity

Published: November 2019

Abstract
Hepatitis B virus (HBV) is an important pathogen responsible for serious diseases like chronic hepatitis, cirrhosis and liver cancer. Turkey is located in the intermediate endemic region based on the average HBV surface antigen positivity. The high replication capacity of HBV and the lack of proofreading activity of the reverse transcriptase (RT) enzyme makes the virus prone to mutations. In this study, S gene mutation which is detected in a chronic HBV case without any follow-up and treatment is presented. Although patient was HBsAg negative and anti-HBs positive in the examinations, the mutation analysis was performed upon the high level of HBV DNA load and sG145R (vaccine escape) mutation in S gene region and rtI169F, rtV173L, rtA181G and rtT184R mutations in pol gene region were detected. S gene region mutations may cause false negatives in diagnostic assays that detect HBsAg. At the same time, it is a public health problem because these HBV variants can also be transmitted by vertical and horizontal routes. Therefore, when atypical serological profiles are encountered, it is of utmost importance to remember S gene mutations and perform necessary analyses.
The evaluation of the reverse algorithm for syphilis screening in blood donors
Authors: Berkem Rukiye , Karakoç Ayşe Esra 
Published: November 2019

Abstract

Background: In Turkey, prior to transfusion and apheresis, it is mandatory to screen blood for HBsAg, anti-HCV, anti-HIV 1/2, and syphilis. In recent years, efforts have been made to create effective diagnostic algorithms for screening, and as a screening strategy, many countries have switched from traditional algorithms to reverse algorithms. This study was carried out to evaluate the results we obtained after changing to chemiluminescence immunoassay (CLIA) based reverse algorithm, which is more sensitive and specific than the traditional algorithm and VDRL test we currently use for syphilis screening.

Methods: The screening algorithm was initiated with the treponemal CLIA method. The reactive samples were tested using a nontreponemal test VDRL and a second treponemal test TPHA. In the descriptive analyses, the averages, numbers, and percentage distributions were calculated. The group comparisons were undertaken with the chi-square test, accepting p < 0.05 as statistically significant.

Results: Of the 5,053 samples that were tested with CLIA syphilis TPA assay 5,043 were negative (99.802%) and 10 were positive reactive (0.198%), and the difference between the two was statistically significant (p < 0.001). Ten samples that were recurrently reactive were analyzed by VDRL and TPHA tests simultaneously. VDRL was negative in all 10 samples, whereas TPHA was negative in one sample, but positive in nine samples at a titer of ≥1/160.

Conclusion: Based on the results of this study, we decided to use the CLIA method and reverse algorithm instead of using the traditional algorithm and VDRL as the initial screening method.

Abstract
Wandering spleen is a very rare clinical condition characterized by spleen absence in the normal anatomical location in the upper left quadrant of the abdomen and its presence at another location in the abdomen or pelvis. The ectopic spleen is extremely rare in children, where its increased mobility is the result of a congenital disturbance of the fixation for the anterior wall due to the absence or weakness of the supporting ligaments. Wandering spleen is usually asymptomatic, but its torsion is possible, as well as infarction or rupture which demand an urgent diagnosis and surgical treatment. The diagnosis of wandering spleen can easily be overlooked due to low incidence and insufficient clinical experience, which multiplies patient's risk from life-threatening conditions. We present a case of wandering spleen in an 11-year-old girl with acute abdominal pain, which after ultrasound examination raised suspicion on the right adrenal gland tumor. Additional diagnostics verified an ectopic spleen in the right adrenal box, after which the recommended preventive splenopexy was seriously considered. Due to the fixation of the vital spleen in the new position, but also the negative attitude of the parents towards the surgical intervention, clinical monitoring was selected, with exclusion of intense physical activity that carries the risk of traumatization of the spleen. As the girl has been in good health for over 3 years and without symptoms, we consider that the selection of conservative access although difficult, was correct. We hope that our experience in treating wandering spleen in girls will increase the number of valid facts about this rare condition.

Published: November 2019

Abstract
This prospective study was conducted for the clinical evaluation of pain severity and knee functionality following PRP injections with different leukocyte (WBC) concentrations applied to cases diagnosed with knee osteoarthritis. A total of 109 patients were included in the study. According to the leukocyte content the PRP injections were prepared as low-leukocyte content PRP (P-PRP) and high concentration leukocyte content PRP (L-PRP). Patients were divided into 2 groups. Group 1 (n=44) received low-leukocyte content PRP and Group II (n = 65) received high-leukocyte content PRP. The patients were evaluated clinically with Visual Analog Scale (VAS) and Knee Society Score (KSS). The changes in the PLT levels of the L-PRP group after the procedure compared to the levels prior to the procedure were found to be statistically significantly greater than the changes in the PPRP group. The mean VAS score of all the cases before treatment was 9.05±0.91 and this score decreased to 3.71±1.46 within 12 months. The increases in the mean Knee Society Score (KSS) values were determined as 16.92±1.97 within 6 months and 16.89±2.97 within 12 months in the P-PRP group and 19.71±1.24 within 6 months and 19.86±0.42 within 12 months in the L-PRP group. The most important aspect of this study is that, in contrast to many other studies, the results continued after the 6th month and were reported to be good in the 12th month. It was also recorded that L-PRP was clinically superior to P-PRP in the treatment of early stage knee osteoarthritis.
