Published: September 2018

El contenido y comportamiento del carbono orgánico del suelo (COS) en regiones áridas; a través, del tiempo son desconocidos, aun cuando las enmiendas de estiércol bovino en estos suelos han tomado importancia en los sistemas agrícolas extensivos de esas regiones, no existe información que revele los cambios en el estatus del COS. Por tal motivo, los objetivos de esta investigación fueron establecer la distribución del contenido de COS del municipio de Matamoros, Coahuila y determinar los cambios en su concentración, través del tiempo. Muestras de suelo de la capa superficial (0-30 cm) en el año 2015, se colectaron, para estimar el contenido de COS. Estos datos y sus georreferencias se utilizaron para realizar una interpolación con el método geoestadístico Krigin Ordinario y obtener un mapa temático de distribución de COS. Asimismo, datos base de COS del año 2002, adquiridos de un trabajo previo, se emplearon para obtener otro mapa temático del municipio. Los mapas fueron comparados con una tabla de referencias cruzadas y con el índice de concordancia Kappa (ICK). Los resultados mostraron que los mapas no son iguales, como lo confirmo el ICK= 0.1, de tal manera que en trece años el COS se incrementó 65 511.88 Mg. La determinación del contenido de COS y el establecimiento de su distribución espacial, así como su comparación con datos y mapas base de COS existentes, permitieron determinar los cambios en los contenidos de COS a través del tiempo.

Published: September 2018

El financiamiento a través del crédito permite aumentar las actividades productivas de los agricultores y las oportunidades de acceso al mercado, sus ingresos y de esta manera mejorar la calidad de vida de las familias. El objetivo de este trabajo fue analizar la distribución de créditos que ha realizado la Unión de Crédito ‘Mixta Plan Puebla’ (UCMPP) del periodo de 1993 hasta 2005, con la finalidad de conocer si éstos han sido destinados a los municipios menos desarrollados donde fue su área de mayor dispersión y si se dio seguimiento a los créditos otorgados. Para alcanzar dicho propósito se llevó una investigación de campo que consistió en la aplicación de 86 encuestas a los socios, así como la elaboración de una base de datos históricos de los municipios. Dentro de los resultados se observa que 61% de los créditos están distribuidos en comunidades urbanas, mientras que 39% en comunidades rurales, de los cuales 56% son de mediana marginación y 59% de baja migración.

Authors: Coutiño Estrada Bulmaro , Vidal Martínez Víctor A. , Vázquez Carrillo Gricelda
Published: September 2018

Pocos productores de maíz pueden adquirir semilla certificada de híbridos, por lo que la otra opción para agricultores de escasos recursos es adquirir semilla certificada de variedades de polinización libre. En Chiapas se liberó la variedad V-526 en 1983 y fue muy apreciada por los productores llegándose a sembrar hasta 50 000 ha en su primer año con semilla certificada. En el año 2000 se inició un esquema de selección combinada de familias de hermanos completos en la V-526 con objeto de renovarla, incrementar su potencial de rendimiento, pero sin cambiar sus características fenotípicas de planta y mazorca. Después de tres ciclos de selección se evaluaron las variedades experimentales formadas y se detectó una de ellas como sobresaliente, a la cual se le denominó V562. Esta nueva variedad puede producir hasta 1.4 t más que la V-526, con un rendimiento potencial de 7.8 t ha-1, bajo condiciones de buen temporal. Sus características de grano son excelentes para la elaboración de tortillas de color blanco y buena calidad.

Authors: Byvaltsev V. A. , Sorokovikov V. A. , Kalinin A. A. , Okoneshnikova A. K.
Published: September 2018

Background. Periarticular cysts (PC) of facet joints is a rare pathology in neurosurgical practice. The concept of PC is applicable for all cysts that are located either pararticularly in the region of facet joints, or start from them.

Material and methods. A systematic search was performed in medical databases: Medline, RINC, EMedicine, UMKB, Pubmed on the relevant topic in Russian and English. The search query includes  words: arcuate joint, periarticular cyst, clinic, diagnosis, surgical  treatment. One of the significant factors of PC development is the  instability of the vertebralmotor segment of both degenerative and post-traumatic character.

Results. The result of the literature review was the writing of a clinical lecture, the current state of the issue of etiopathogenesis, diagnosis and management of patients with  periarticular cysts of facet joints was studied. The article gives a  clinical example of surgical treatment of a patient with a periarticular cyst at the level of LIV-LV on the right.

Conclusion. Periarticular cysts of facet joints are one of the factors of compression of cauda equina roots, with surgical treatment being  a radical and effective way of treatment. A detailed study of this  pathology is a promising direction in spinal neurosurgery. Further  research is required on comparative analysis of clinical and  instrumental efficacy of various methods of surgical treatment of periarticular cysts of facet joints.

Published: September 2018

The analysis of vacancies and job offers for doctors, especially information on the declared amount of wages and benefits, allows  not only to study the need for personnel, but also to study the level  of motivation of candidates for medical posts. The aim of the study  was to analyze vacancies and job offers for doctors from state  medical organizations of the Irkutsk region. The study was  conducted using the method of continuous statistical analysis of job  offers for physicians posted on the official website of the Ministry of  Health of the Irkutsk region. The public sector of the healthcare  system in the Irkutsk region provides a large number of vacancies  for unemployed doctors and young professionals. Declared in job  advertisements, the salary level of doctors is below the level  reflected in regional state reports on the health of the population and  the organization of health care. There is a lag in the salaries of  medical workers from the average for the region, as well as the  backlog of the Irkutsk region in this indicator from the Russian  Federation. When comparing the municipalities of the region to the  maximum and minimum declared wage levels, it is revealed that the  difference between them is almost fourfold. Although the most  demanded are doctors who provide primary health care, the need for these specialists does not correlate with the level of wages offered to them in vacancy announcements. Fourfold excess of the maximum  declared wage level over the minimum in the municipal formations of the region is not a consequence of taking into account difficult  working conditions in hard-to-reach areas, but is due exclusively to factors of economic nature.

Published: September 2018

Adhesive process in the abdominal cavity is one of the most frequent complications of intra-abdominal surgery.

The aim of the study was to evaluate the activation of the JNK MAPK cascade during the experimental adhesion process.

Materials and methods. Experimental studies were performed on 40 male Wistar rats (9 months old). We modeled the adhesive  process in the abdominal cavity. At the time from 2 hours (2, 6, 12  hours) to 30 days (1, 3, 7, 14, 30 days), a JNK MAPK cascade was  evaluated in the zone of damage to the serosa using  immunohistochemical methods (painting on JNK1 Phospho (pT183) /  JNK2 Phospho (pT183) / JNK3 Phospho (pT221)) and real-time  PCR (the MAP Kinase Signaling Pathway RT2 - Profiler ™ PCR Array  (Qiagen) kit). 

Results. We have found that the expression of the  phosphorylated part of the JNK MAPK cascades has an undulating dynamics with two  peaks on the 3rd and 14th day. It has been determined that all  three JNK cascades are involved in the process, and all JNK cascades are synchronously activated on the 3rd day (JNK1 increases 12-fold  in comparison with the group of intact animals, JNK2 is 8-fold, JNK3  is 10-fold). On the 14th day, the activity of the JNK3 cascade is the  most intensively increased – 30 times (for JNK1 – about 6 times,  JNK2 – 12 times). 

 

Conclusion. Significant activation of MARK cascades has been established on the 14th day after traumatic injury, which indicates the need for long-term prevention of posttraumatic changes, in particular, the formation of adhesions.

Authors: Iunikhina O. V. , Kompanets G. G.
Published: September 2018

Hemorrhagic fever with renal syndrome is a widespread natural-borne infection of orthohantavirus etiology in the territory of the  Russian Federation. Male patients of working age dominated, which  is associated with their professional and social activity. Although the  rate of children among all cases of this infection in our country is 2.5 %, the variety of clinical symptoms causes the problem in the diagnostic of this disease.

The purpose of this work was to study the characteristics of  orthohantavirus infection among children and adolescents of  Primorski Krai.

Materials and methods. A retrospective analysis of 60 serologically confirmed cases of orthohantavirus infection in children and  adolescents was carried out. Patients were divided into age  subgroups with a link to the possibility of infection in the urban or rural locations.

Results. The prevalence of men aged 15-17 years among all studied patients was established. However, children starting from 3 years old are at risk of infection in rural areas of the region too, which is  related to proximity of natural landscapes. Circulation in the  Primorski Krai of two pathogenic orthohantaviruses (Hantaan and  Seoul) causes yearround registration of human orthohantavirus infection, including children.

Conclusion. The Primorski Krai is an endemic territory for orthohantavirus infection, with the simultaneous circulation of  several orthohantaviruses. Risk of infection within all categories of  the population, including children, in whom the disease can occur  more often in a moderate form and with variety of different  symptoms, is related with the activation of the epizootic process in the rodent’s populations.

Authors: Nugroho Agung
Published: September 2018

Social media is currently an online media that is widely accessed in the world. Microblogging services such as Twitter allow users to write about various things they experience or write reviews of a product, service, public figures and so on. This can be used to take opinion or sentiment towards an entity that is being discussed on social media such as Twitter. This study utilizes these data to determine public opinion or sentiment regarding public perceptions of the issue of rising electricity tariffs. Opinion taking is based on three classes namely positive, negative and neutral. Users often use non-standard word abbreviations or spelling, this can complicate the process and accuracy of classification results. In this study the authors apply text-preprocessing in handling these problems. For feature extraction, n-gram and classification methods are used using the Naive Bayes classifier. From the results of the research that has been done, the most negative sentiments are formed in response to the issue of the increase in basic electricity tariffs. In addition, from the results of testing with the method of cross validation and confusion matrix it is known that the accuracy of the naïve Bayes method reaches 89.67% before applying n-gram, and the accuracy rate increases 2.33% after applying n-gram characters to 92.00%. It is proven that the application of the n-gram extraction feature can increase the accuracy of the naïve Bayes method.
MODERN ASPECTS OF HUMAN PAPILLOMAVIRUS VACCINATION
Authors: Alyautdina O. S. , Darmostukova M. A.
Published: September 2018

Human papillomavirus refers to DNA-containing viruses and infects the skin and mucosal epithelium. One common way is to change the  expression of cellular genes by integrating the viral genome into  cellular DNA. The reason for the resistance of HPV infection is the  presence of complex mechanisms of inhibiting the immune response  of the macroorganism. An important infectious agent involved in  carcinogenesis are human papillomavirus (HPV) viruses, which cause  a significant part of oncological diseases. Viruses create the  prerequisites for malignant cells by introducing an oncogene or  blockade of suppressor proteins in cells to disrupt the regulation of  cell division. Two proteins, E6 and E7, encoded by the DNA of the  virus, play a leading role in this process. More than 100 different types of HPV have been identified, and approximately one- third of them infect epithelial cells in  the genital tract. HPV is also  the cause of carcinoma of the penis, vulva, anus and contribute to  the occurrence of more than 40 % of oropharyngeal cancer. To date,  the most effective way to combat HPV infection is  immunoprophylaxis. To date, there are three commercially available  HPV vaccines: Cervarix®, Gardasil®, Gardasil®9. These three  vaccines effectively prevent HPV infections, causing the production of neutralizing antibodies that bind to viral particles and block their  entry into host cells. However, these vaccines are not effective in  eliminating pre-existing infections. Currently, there are no  therapeutic vaccines against HPV, approved for use in humans. The  review discusses the types of vaccines against HPV infection and the effectiveness of vaccination.

Authors: Bence A. R. , García J. , Fernández E. , Morrell E. , Cantón G.
Published: September 2018

Se describe un presunto caso de intoxicación con ionóforos en búfalas de un tambo de la Provincia de Buenos Aires, Argentina, las cuales habían consumido pasturas y ración comercial formulada para bovinos en ordeñe, conteniendo monensina. Murieron 5 de las 50 búfalas en ordeñe, manifestando taquipnea, disnea, sialorrea, decúbito y muerte. Durante la necropsia se observó hidrotórax, ascitis, hígado con puntillado hemorrágico, edema en vesícula biliar, duodeno y diafragma, así como coloración blanquecina en miocardio. Microscópicamente se evidenciaron miocarditis y miositis necrotizante no supurativa, hepatitis centrolobulillar necrotizante y edema pulmonar severo. La actividad de las enzimas creatinfosfoquinasa y aspartato amino transferasa estaba elevada en animales muestreados al azar. Los datos anamnésicos y clínico-patológicos fueron suficientes para determinar a la intoxicación por ionóforos como el diagnóstico presuntivo de esta mortandad, siendo éste el primer reporte en búfalos de Argentina
Distribución de beta-catenina en lesiones displásicas de colon en ratas alimentadas con leche de búfala
Authors: Catuogno M. S. , Montenegro M. A. , S. Negrette M.
Published: September 2018

El objetivo del presente trabajo fue determinar la distribución de beta-catenina en lesiones displásicas (LD) de colon en ratas alimentadas con leche de búfala. Se utilizaron ratas Wistar machos de 6 semanas, que recibieron diferentes dietas lácteas durante 123 y 240 días. Se suministraron dos tipos de dietas lácteas, una estándar, proveniente de búfalas alimentadas con pasturas naturales, y otra mejorada obtenida de búfalas suplementadas con aceite de pescado, con alto contenido en ácido linoleico conjugado y omega-3. Las LD fueron inducidas por el carcinógeno 1,2-dimetil-hidrazina. Para detectar beta-catenina se empleó la técnica de inmunohistoquímica. Las células epiteliales colónicas mostraron claramente expresión membranosa de beta-catenina. En células superficiales, la proteína pudo ser identificada también en el citoplasma, pero con una tinción membranosa más débil. En las células que estaban localizadas hacia la profundidad de la mucosa, se observó falta de proteína en el citoplasma, permaneciendo en la membrana citoplasmática. Los enterocitos ubicados sobre la muscular de la mucosa mostraron tinción membranosa débil en comparación con las membranas de las células superficiales. No se observó beta-catenina en núcleos de células normales. En LD de ratas alimentadas con leche de búfala, la distribución de beta-catenina cambió sustancialmente acorde a la severidad de la displasia. Estos hallazgos podrían ser de utilidad para la detección de lesiones pre-carcinomatosas en estadios tempranos

La bursitis infecciosa aguda, conocida como enfermedad de Gumboro, es una afección viral muy contagiosa, económicamente importante por afectar severamente a los pollos producidos comercialmente en el mundo entero. El objetivo del trabajo fue comparar, a los 21 y 28 días de edad, los niveles de anticuerpos post-vacunales contra dicha enfermedad en pollos parrilleros inoculados con vacuna recombinante in ovo a los 18 días en planta de incubación, así como medir los niveles de anticuerpos a los 1, 7, 14, 21, 28 y 35 días de edad a fin de trazar la curva de anticuerpos post-vacunales. De una población total de 200 pollitos parrilleros, 28 fueron seleccionados al azar para la extracción de sangre, que se realizó por punción cardiaca a los 1, 7 y 14 días de edad, así como por punción de la vena alar a los 21, 28 y 35 días de edad. Las muestras fueron procesadas mediante el método ELISA indirecto, utilizándose un kit comercial (Idexx Lab). Los resultados correspondientes a los títulos geométricos promedio de anticuerpos fueron: día 1: 6955, día 7: 3678, día 14: 808, día 21: 34, día 28: 8, y día 35: 3013. No se encontraron diferencias estadísticamente significativas (p>0,05) en los niveles de anticuerpos entre los días 21 y 28, siendo los mismos considerados como no protectivos

Published: September 2018

En la actualidad el sistema agrícola tiene como principal propósito el aumento de la producción con el fin de garantizar el abastecimiento y distribución de sus productos en el mercado, sea interno o externo, generando así mayor rentabilidad económica. Esto trae aparejado la implementación de diferentes agroquímicos que, vertidos al ambiente, pueden tener un impacto negativo sobre la flora, fauna, cuerpos hídricos e incluso en seres humanos. El glifosato (Roundup Full II) es uno de los herbicidas más empleados y sus beneficios están siendo objetados por las desventajas que podría provocar su utilización en forma excesiva. El objetivo de este trabajo fue evaluar la ocurrencia de alteraciones citoplasmáticas en eritrocitos de sábalo (Prochilodus lineatus) expuestos en un ensayo crónico al herbicida glifosato. Se utilizaron ocho ejemplares juveniles de sábalo, los que fueron distribuidos aleatoriamente en dos tratamientos según la adición del herbicida: control (C) sin adición y tratado (T) con adición de 0,1 µg/l de glifosato. El ensayo tuvo una duración de 70 días. Para la preparación de los frotis sanguíneos se procedió a la extracción de sangre periférica por punción de la vena caudal. Las alteraciones observadas fueron presencia de vacuolas citoplasmáticas, dacriocitosis y microcitosis. Estas anormalidades se presentaron con mayor frecuencia en el grupo T con respecto al C. Los resultados obtenidos sugieren la existencia de una respuesta patológica a nivel hemático ante una exposición crónica a la dosis de 0,1 µg/l del herbicida

La importancia de los perros como reservorio en el ciclo doméstico de Trypanosoma cruzi, agente de la enfermedad de Chagas, se ha visto reforzada por las altas prevalencias halladas en caninos de barrios periféricos, lo cual junto a la precariedad de viviendas, patios y su entorno, contribuyen a la presencia endémica de la enfermedad. Se consideró el grado de infección canina a T. cruzi y su asociación con factores de riesgo, utilizándose como indicador epidemiológico el porcentaje de animales infectados en el barrio Bañado Norte de la ciudad de Corrientes, dimensionándose los factores de riesgo surgidos de las características de las viviendas. La muestra estuvo conformada por 122 caninos, de los cuales el 58% pertenecían a viviendas tipo A (paredes de madera, piso de tierra) y el 42% a tipo B (ladrillos y cemento, respectivamente). La prevalencia total fue de 54%, es decir que resultaron positivos 66 sueros, de los cuales 41 pertenecían a caninos que habitaban casas tipo A y los 25 restantes a casas tipo B. Si bien la prevalencia hallada fue alta, para poder inferir la situación existente a nivel poblacional se debería aumentar el tamaño muestral. El valor de 1,41 del riesgo relativo calculado para asociar la presencia de infección con el tipo de vivienda, podría interpretarse como que los caninos procedentes de viviendas tipo A tienen mayor probabilidad de adquirir la infección, aunque el análisis estadístico no arrojó evidencias significativas para afirmar tal asociación

Sulfur (S) isotope compositions of pyrites in the sedimentary record have played an important part in our understanding of biogeochemical cycling in the geologic record. However, the kinetics of pyritization are complex and depend strongly on the reactivity and mineralogy of available iron. As a second major sink for sulfide in anoxic sediments, organic matter (OM) provides essential context for reconstructing the distribution and isotopic composition of environmental sulfide. To first order, roughly parallel pyrite and OM δ34S profiles reflect changes in sulfide, while independent patterns require alternative explanations, including changes in iron availability or OM characteristics. We apply this framework to Ocean Anoxic Event 2 (OAE-2, 94 Mya), a period of enhanced reduced C and S burial (in OM and pyrite) that was associated with expanded marine anoxia. We present paired S-isotope records for pyrite and OM along with profiles of OM S:C ratio and S redox speciation from four well-characterized lithologic sections (Pont d’Issole, Cismon, Tarfaya Basin, and Demerara Rise) to reconstruct both local redox structure and global mechanisms impacting the C, S and Fe cycles around OAE-2. OM sulfurization appears to be a major control on OM preservation at all four sites. Similar to modern anoxic environments, there is a positive correlation between OM S:C ratios and OM concentrations for sites with more reducing conditions, implying a link between OM sulfurization and burial. At consistently anoxic sites like Tarfaya Basin and Demerara Rise, strongly sulfurized OM with a consistent S redox speciation and S-isotope composition most likely formed rapidly in sinking particles before, during, and after OAE-2. Particle-hosted OM sulfurization may therefore have been a central mechanism facilitating the massive burial of OM in anoxic environments during this and other periods of enhanced global carbon burial. At the same time, a nearly 25‰ negative shift in the δ34S values of pyrite – but not OM – occurs at multiple, globally distributed sites near the onset of OAE-2, indicating slower pyritization reactions that likely reflect changes in iron delivery due to expanding regional or global anoxia. The combination of pyrite and organic S isotopes thus provides novel constraints on the interwoven cycles of carbon, iron, and sulfur across a major carbon cycle perturbation.

Confirmatory factor analysis (CFA) has been frequently applied to executive function measurement since first used to identify a three-factor model of inhibition, updating, and shifting; however, subsequent CFAs have supported inconsistent models across the lifespan, ranging from unidimensional to nested-factor models (i.e., bifactor without inhibition). This systematic review summarized CFAs on performance-based tests of executive functions and reanalyzed summary data to identify best-fitting models. Eligible CFAs involved 46 samples (N=9,756). The most frequently accepted models varied by age (i.e., preschool=one/two-factor; school-age=three-factor; adolescent/adult=three/nested-factor; older adult=two/three-factor), and most often included updating/working memory, inhibition, and shifting factors. A bootstrap reanalysis simulated 5,000 samples from 21 correlation atrices (11 child/adolescent; 10 adult) from studies including the three most common factors, fitting seven competing models. Model results were summarized as the mean percent accepted (i.e., average rate at which models converged and met fit thresholds: CFI≥.90/RMSEA≤.08) and mean percent selected (i.e., average rate at which a model showed superior fit to other models: ∆CFI≥.005/.010/∆RMSEA≤-.010/-.015). No model consistently converged and met fit criteria in all samples. Among adult samples, the nested-factor was accepted (41-42%) and selected (8-30%) most often. Among child/adolescent samples, the unidimensional model was accepted (32-36%) and selected (21-53%) most often, with some support for two-factor models without a differentiated shifting factor. Results show some evidence for greater unidimensionality of executive function among child/adolescent samples and both unity and diversity among adult samples. However, low rates of model acceptance/selection suggest possible bias towards the publication of well-fitting, but potentially non-replicable models with underpowered samples.
