La instrucción del movimiento durante actividades de copia con escritores y escritoras principiantes
Authors: Muñoz-Abrines María Loreto
Published: April 2020

El presente artículo tiene como objetivo revisar sustento teórico y empírico que aporte a repensar las prácticas pedagógicas que se están utilizando con personas escritoras principiantes para favorecer el proceso de automatización de habilidades grafomotoras durante actividades de copia. Lo anterior, porque siendo dicha actividad necesaria para desarrollar habilidades grafomotoras y en consecuencia para el proceso de automatización; la copia mecánica, reiterada e inconsciente resulta ineficiente y contraproducente. No solo no aporta a la construcción de memoria muscular, aspecto clave para la automatización del trazado, sino que las exigencias trascienden las capacidades motrices de la niñez. Se concluye que para que las prácticas de copia resulten respetuosas con dichas capacidades motrices y aporten a la automatización de las habilidades grafomotoras, se deben focalizar en la construcción de memoria muscular por medio de la instrucción del movimiento utilizando letra grande.
ACA Medicaid Expansion and Insurance Coverage Among New Mothers Living in Poverty
Authors: Johnston Emily M. , McMorrow Stacey , Thomas Tyler W. , Kenney Genevieve M.
Published: April 2020

BACKGROUND:

Medicaid plays a critical role during the perinatal period, but pregnancy-related Medicaid eligibility only extends for 60 days post partum. In 2014, the Affordable Care Act’s (ACA’s) Medicaid expansions increased adult Medicaid eligibility to 138% of the federal poverty level in participating states, allowing eligible new mothers to remain covered after pregnancy-related coverage expires. We investigate the impact of ACA Medicaid expansions on insurance coverage among new mothers living in poverty.

METHODS:

We define new mothers living in poverty as women ages 19 to 44 with incomes below the federal poverty level who report giving birth in the past 12 months. We use 2010–2017 American Community Survey data and a difference-in-differences approach using parental Medicaid-eligibility thresholds to estimate the effect of ACA Medicaid expansions on insurance coverage among poor new mothers.

RESULTS:

A 100-percentage-point increase in parental Medicaid-eligibility is associated with an 8.8-percentage-point decrease (P < .001) in uninsurance, a 13.2-percentage-point increase (P < .001) in Medicaid coverage, and a 4.4-percentage-point decrease in private or other coverage (P = .001) among poor new mothers. The average increase in Medicaid eligibility is associated with a 28% decrease in uninsurance, a 13% increase in Medicaid coverage, and an 18% decline in private or other insurance among poor new mothers in expansion states. However, in 2017, there were ∼142 000 remaining uninsured, poor new mothers.

CONCLUSIONS:

ACA Medicaid expansions are associated with increased Medicaid coverage and reduced uninsurance among poor new mothers. Opportunities remain for expansion and nonexpansion states to increase insurance coverage among new mothers living in poverty.
Conflicto, negociación y postconflicto en la confrontación Gobierno-FARC-EP, Colombia
Authors: Botero-Torres Raúl
Published: April 2020

Las negociaciones de paz en La Habana entre el Gobierno Nacional de Colombia y las Fuerzas Armadas Revolucionarias de Colombia - Ejército del Pueblo (FARC-EP) se constituyó en uno de los hechos más significativos de la historia política de Colombia en los últimos cien años. Fue de alguna manera el punto de cierre a una de las formas de violencia que ha padecido este país. Examinar esas formas violentas, el proceso de negociación y lo que ha venido después es nuestra obligación como académicos. En este examen emergen; de un lado, la desigualdad entre los distintos sectores sociales y el ejercicio hegemónico del poder por parte de las élites dominantes, como algunas de las causas; y de otro, el conflicto armado con su secuela de muertos y desplazados como la consecuencia casi obvia de lo anterior. Ser capaces de entender lo que pasa, tal vez no sea la solución al conflicto, pero si es el comienzo para entender los procesos históricos y sociales que han ocurrido, que están sucediendo y que muy probablemente van a darse en un futuro más o menos inmediato.
Breve contexto legal y conceptual de la tenencia de animales domésticos, silvestres y exóticos en Colombia
Authors: Vásquez-Restrepo Juan D. , Rubio-Rocha Laura
Published: April 2020

El objetivo de este artículo es hacer una revisión y recopilación de la normativa acerca de la tenencia de diferentes tipos de animales en Colombia, así como un análisis comparativo entre los términos doméstico, silvestre y exótico presentes en la legislación y los conceptos biológicos para las mismas nociones. Se encontró que algunas de las definiciones existentes son generales y pueden ocasionar problemas de interpretación al momento de aplicar la normatividad. Colombia es un país con una legislación que en materia de fauna ha priorizado la protección de las especies silvestres, e incorporado recientemente aspectos relacionados con el bienestar animal. Sin embargo, la ausencia de una reglamentación específica acerca de la tenencia de fauna exótica, puede propiciar el aumento de situaciones de ilegalidad y su consecuente riesgo para los ecosistemas.

The author studies 1 Thessalonians 2: 7-12 about teacher qualifications. This study departs from the writer's anxiety about the condition of the teacher. Where teachers are currently required to perform tasks according to the educational qualifications of each level. But in reality, there are still many teachers who have not met the minimum bachelor requirements. One obstacle is the distance to go to college and the age that is not young anymore. As a result, many teachers have difficulty in accessing education. With that problem, the author examines the qualifications of teachers based on 1 Thessalonians 2: 7-12. The method used by the author is qualitative. The method used to trace the actual state of the object of research. The study used is exegese. Exegese tries to understand the text from various aspects. Based on the study conducted by the author in this paper, there are two important things that need to be learned, namely hospitality in love. And the example of struggle is an example for many people. Teaching is a very important task in Paul's ministry. Paul gave an example of how to work hard in work as a teacher, providing holistic service. This paper is a teacher qualification study that touches on nature that must be possessed by a teacher.

The Interpenetrating
Polymer Network (IPN) structure was obtained by gamma radiation of solution of
polyethylene glycol (PEG)(35000MW) in an acrylonitrile (AN) to 14 and 60kGy
doses were amidoximated with hydroxylamine solution at optimum amidoximation
conditions. Effects of pH (2-10) and mNi/mIPN ratio (0.002-0.5) in Ni2+adsorption
were examined by batch process and optimum values were determined as 8 and 0.4
for both doses, respectively. Also, the effect of flow rate to Ni2+
adsorption was examined by the reflux flow process with a fixed-bed reactor at
room temperature. Optimum flow rate is determined as 6mL/s at optimum pH. Ni2+
adsorption studies were carried out in batch (pH=6 and 8) and flow (pH=8) systems.
Maximum adsorption values reached for irradiated to 14 and 60kGy doses and
amidoximated IPNs were given as 105 and 99 mgNi/gIPN in batch system (pH=6),
378 and 361 mgNi/gIPN in batch system (pH=8) and 891 and 673mgNi/gIPN in flow
system (pH=8), respectively. Maximum elution
efficiency was obtained for HCl as being 99.5% and 66.1% for IPNs irradiated
to 14 and 60kGy doses and amidoximated, respectively. FTIR results showed that
HCl caused structural deformation. Minimum elution
efficiency was obtained for (NH4)2CO3 as
being 60.1% and 58.2% for IPNs irradiated to 14 and 60kGy, respectively, by the
minimum deformation.
Camera-trap records of breeding Eurasian lynx (Lynx lynx) at the Mount Ilgaz Wildlife Reserve
Authors: SOYUMERT Anil
Published: April 2020

Breeding seasons are one of the most important periods for the life cycle of large mammals. The young individuals of large carnivore mammals are normally dependent on the female for food and protection. Therefore, availability of the sources and human disturbance at the breeding site are critical for a successful breeding season. The breeding site is of vital importance to the survival of the newborns and thus to the trends in the population size. The present study assesses the breeding sites for the Eurasian lynx (Lynx lynx) based on camera-trapping surveys at Mount Ilgaz Wildlife Reserve in the province of Kastamonu. The surveys were conducted continuously over a four year period (2014-2018) and the results indicate that the Eurasian lynx breeding sites have also been used by the juvenile individuals of two other top predator large mammals, brown bear (Ursus arctos) and grey wolf (Canis lupus) and the juveniles of their prey species, red deer (Cervus elaphus) and brown hare (Lepus europaeus). Consequently, an effective conservation plan managing the breeding sites as core areas, will significantly contribute to the protection of the Eurasian lynx and other wildlife populations in the Western Black Sea Region of Anatolia.
Shear strength of interface between high-performance concrete and claystone in the context of a French radioactive waste repository project
Authors: Liu Zaobao , Shao Jianfu , Zha Wenhua , Xie Shouyi , Bourbon Xavier , Camps Guillaume
Published: April 2020

The Callovo-Oxfordian (COx) claystone is chosen as a potential geological barrier for the geological repository of radioactive waste in France, and high-performance concrete is used as a sealing plug and lining in repository facilities. In this study, the shear strength of the interface between the concrete and claystone is investigated in particular. Ultra-high-performance (UHP) concrete is directly cast and cured beside a COx claystone semi-cylinder to make a cylindrical specimen including an interface. First, a microscopic analysis of the interface surfaces using scanned electronic microscope images is presented. It is shown that the adhesion of the UHP concrete to the COx claystone is of good quality and there is almost no initial interface aperture between the two materials. By using a home-designed original device, a series of direct shear tests is performed on cylinder specimens with interface under different confining stresses. The interface deformation and shear strength are quantitatively analysed. It is found that the interface has a bonded cohesion and the shear strength can be approximated by a non-linear function of normal stress. In most cases, the shear deformation does not generate an opening but rather a closure of the interface. The morphology of the sheared interface is also analysed by optical microscopic scanning images.
Key factors influencing the implementation of three-dimensional printing in construction
Authors: Umar Tariq
Published: April 2020

Due to its wider applications and advantages, three-dimensional (3D) printing has attracted the attention of various industries in the past years. Although the implementation of 3D printing in many industries still has challenges, progress in the construction industry is particularly slow. This paper explores the key factors that influence 3D printing adaptation and implementation in construction. A qualitative research method considering a systematic review was adopted to achieve this aim. Relevant data spanning over a period of 20 years (2000–2019) considering four main databases were collected using specified keywords. A total of 137 published articles were downloaded, and 43 were finally selected after the screening criteria had been imposed. The results from this review enabled categorisation of the derived factors broadly into four categories: technology, organisation, environment and cost. Each of these main factors is constituted by subfactors. An understanding of these factors will be helpful in developing effective strategies towards adaptation and implementation of 3D printing in the construction industry. Since industry characteristics vary from region to region, the significance of these factors in various regions could be different and needs to be investigated further.

Current evidence indicates that the minimum light intensity of photo curing units required to polymerize in a reliable way a composite resin, in increments of 2mm, is 300mW/cm2. The recent introduction of new generations of composite resin materials for large volume increments, partially contrasts with ISO 4049 (2009), calling for the use of light intensity of 1,000mW/cm2. Therefore, it is considered relevant to carry out periodic measurements of the emission intensity of light-curing units of clinical use. The aim of this study was to test the intensity [mW/cm2] of a representative sample of tungsten-halogen and LED photopolymerization units used in private and public health service in different areas of the Valparaíso Region in Chile. This was achieved through the use of dental radiometers, without considering the variables of intensity modification over time (either spontaneously, by undesirable inherent characteristics of the device, or by programs of intensity modification in time), or the density of accumulated power needed. This in vitro diagnostic test, evaluated a sample of 507 units, 107 halogen and 400 LED, for a period of around one month, using two radiometers as measuring instruments. For LED units the Bluephase Meter® radiometer, from Ivoclar-VivadentTM was used, and for halogen units we used the Coltolux® from ColténeTM. As a result, 85% of the LED and halogen units achieved the minimum requirements of intensity needed for the polymerization of conventional dental biomaterials. However, only 25% from the tested units achieved a power density of 1,000mW/cm2.

Objective: The aim of this study was to investigate loose brackets in relation to various related factors in orthodontic patients who had completed orthodontic treatment. Material and Methods: In this retrospective study, 738 medical records of patients who had undergone comprehensive orthodontic treatment and matched specific inclusion criteria were selected. Paired t-tests and ANOVA, along with the Mann-Whitney test and Kruskal–Wallis analyses were performed to compare the means of variables between selected subgroups. Results: Loose brackets were found most frequently on premolars, followed by incisors and then canines (p<0.01). Male and young patients were found to have a higher incidence of loose brackets compared to female and adult patients (p=0.044 and p<0.01, respectively). The highest correlation coefficient value was found between treatment duration and total number of loose brackets (0.393), which was statistically significant. Conclusions: The frequency of total number of loose brackets increased with younger age group. Premolar teeth were found to be the most commonly affected teeth, followed by incisors and canines. Mandibular teeth presented more loose brackets than maxillary.

Introduction: The process to evaluate the effectiveness of preventive programs involves follow-up and monitoring activities, assessing if these programs really contribute to the improvement of oral health conditions of the target population. Objective: To evaluate the effectiveness of oral health programs, according to their levels of prevention, applied to schoolchildren at educational institutions in Chiclayo and Pimentel, in the district of Lambayeque, Peru. Materials and Methods: A retrospective, longitudinal and descriptive study was carried out on 237 schoolchildren between 6 and 7 years of age, from four educational institutions located in Chiclayo and Pimentel. A record of the oral hygiene index and caries’ incidence was carried out in four stages, including a baseline diagnosis and three follow-up evaluations every six months between 2016 and 2017, with a previously verified calibration process for the oral hygiene index (k=0.86) and for caries registration (k=0.79). Results: A greater effectiveness was observed in programs with level 2 prevention, achieving a progressive decrease in the oral hygiene index from a baseline mean of 2.04 to 1.98 at 6 months, 1.77 at 12 months and 1.64 at 18 months, with significant differences between them. Regarding the incidence of caries in permanent first molars, no significant differences were found in the effectiveness of programs with levels 1 and 2 of prevention, according to mixed factorial ANOVA (p<0.05). Conclusion: Programs with level 2 prevention have a greater effectiveness in terms of improving oral hygiene conditions, with significant differences in comparison to programs with level 1 prevention. No significant differences were found between the effectiveness of Level 1 and 2 programs regarding the incidence of dental caries.

Objective: To evaluate the effect of the application of a flipped learning model for teaching biostatistics to dental students in a Peruvian public university. Methodology: A quasi-experimental, crossover, longitudinal and prospective design was used. A non-probability sampling technique was employed. The sample consisted of 63 students that enrolled in the Biostatistics course at the School of Dentistry at Universidad Nacional Mayor de San Marcos. Students were divided into two groups according to their designated training schedule. The contents of two units were assessed. For the first unit (descriptive statistics), the first group was taught using the flipped learning model and the second group with the master class model. For the second unit (inferential statistics), groups were crossed over. At both periods of the study, cognitive, procedural and attitudinal skills were assessed through previously validated questionnaires. Mann-Whitney U test, Cohen is d and multiple linear regression analysis were performed. Results: the mean total score for the second unit was higher (p<0.001) in the flipped learning group (32.58) compared to the master class guided training group (27.94), presenting a Cohen’s d=0.97. Procedural (9.23 versus 7.80) and attitudinal (15.63 versus 12.90) skills were on average higher in the flipped learning group. Regression analysis resulted in R2=0.245, p=0.003. Conclusion: the flipped learning method achieved a higher content learning in the second unit, compared to the master class model.

Published: April 2020

The paper considers the estimation problem of the autoregressive parameter in the first-order autoregressive process with Gaussian noises when the noise variance is unknown. We propose a non-asymptotic technique to compensate the unknown variance, and then, to construct a point estimator with any prescribed mean square accuracy. Also a fixed-width confidence interval with any prescribed coverage accuracy is proposed. The results of Monte-Carlo simulations are given.
Mercenary Purpose in Theft: Are There Limits To Broad Interpretation?
Authors: Khilyuta V. V.
Published: April 2020

The paper deals with the issue of the modern understanding of the mercenary purpose as an element of theft and its forms — fraud, misappropriation and embezzlement. The author closely analyzes the Plenum of the Supreme Court of the Russian Federation Resolution No. 48 dated 30 November 2017 "On court practice on cases involving fraud, misappropriation and embezzlement" in view of the discussion of understanding mercenary purpose in litigation. The author polemically sets out the point of view that it is impossible to interpret a mercenary purpose in a broad sense — as the ability to dispose of stolen property at their own discretion, including in favor of other persons, whose circle is unlimited. It is proved that the term "lucre" cannot reveal the content of the purpose of theft, since lucre is inherent not only in theft, but also in other crimes. "Lucre" can only indicate the attitude of a person to the act of his behavior, the method of committing a crime, but does not characterize the purpose of his actions, as a result of which the concept of mercenary purpose can be filled with different content. Mercenary motives should determine the existence of a mercenary purpose, and non-mercenary motives should exclude the qualification of committed acts as theft of someone else’s property. The explanation of a mercenary purpose proposed by the Supreme Court of the Russian Federation significantly shifts the scope of the presence of elements of theft and transfers them to an earlier stage. Evening a mercenary purpose with the purpose of gaining (receiving) property benefits is not certain, since property benefits can also be extracted from the illegal use of other people’s property. For the objective classification of theft, the motive of the perpetrator’s behavior and the nature of his actions must be essential. Therefore, from the point of view of subjective elements of theft, its purpose should indicate that such an act is aimed at enriching the perpetrator or other persons, the circle of whom should be limited.
The niche in the uterine cesarean scar: a new problem of women’s reproductive health
Authors: Nozhnitseva Olga N. , Bezhenar Vitaliy F.
Published: April 2020

Hypothesis/aims of study. In the recent decades, the quality of uterine suture repair after a cesarean section is widely discussed, as local thinning of the myometrium forming uterine scar defects, or the so-called scar niche, are relatively common after the operation. The aim of this study was to identify the causes of local thinning of the uterine scar after cesarean section, to determine the effectiveness of existing methods for assessing the uterine scar in non-pregnant women, and to develop a method for surgical correction of this pathology.
Study design, materials and methods. Over 4 years, 175 non-pregnant women with a uterine scar were examined. The 50 of them were diagnosed with the uterine scar niche, with a laparoscopic metroplasty performed in these patients. The effectiveness of the operation was evaluated in the long-term postoperative period.
Results. Performing cesarean section because of weakness of labor activity and a complicated course of the postpartum period are significant factors in the formation of a uterine scar niche (p 0.05). Ultrasound examination and magnetic resonance imaging of the pelvic organs can be used to detect local thinning of the myometrium with a sensitivity of 82% and 96%, and a specificity of 85% and 90%, respectively.
Conclusion. Metroplasty for patients with a diagnosed scar niche can significantly increase the thickness of the myometrium (p 0.05) and reduce the frequency of complaints of such menstrual irregularities as postmenstrual vaginal bleeding, dysmenorrhea, and hypermenorrhea (p 0.05).

Published: April 2020

Hypothesis/aims of study. Recently, due to empowering the improvement of care for patients with traumatic brain injury and creating effective methods of intensive therapy for severe brain lesions of various genesis, there has been a tendency towards an increased number of patients who have gone out of a coma into an unconscious state a vegetative state or an unresponsive wakefulness syndrome (BS / UWS). The functions of the brain stem and hypothalamus in patients in a BS / UWS are preserved. The aim of this study was to evaluate the significance of the relationship between the regulation of sex steroid hormones and the secretion of neurotransmitters.
Study design, materials and methods. The study was performed using systematic analysis and compilation of literature data obtained by foreign and domestic authors over the period from 1931 to 2018.
Results. This article reviews publications covering the relationship between the regulation of sex steroid hormones and the secretion of neurotransmitters, as well as their effect on the reproductive system. The theory of neurosecretion depicting the mechanisms of positive and negative feedback of the synthesis of neurotransmitters and sex steroid hormones, and the characteristics of the secretion machineries for sex hormones with normogonadotropic and hypogonadotropic pituitary insufficiency, and nonendocrine manifestations of the pathology of the hypothalamus is highlighted in this review.
Conclusion. The hormonal profile of patients with chronic disorders of consciousness remains almost unstudied. A further study of the hormonal profile in this patient category will create the prerequisites for the development of pathogenetically substantiated hormone-modifying replacement therapy, which may have a positive effect on the dynamics of recovery of consciousness and improve treatment outcomes.
Applying the “baby nursing model” in under-resourced audiovisual archives in Africa
Authors: Opoku-Boateng Judith
Published: April 2020

It is a well-known fact that there has been extensive documentation of African traditional arts in post-colonial Africa, which has contributed to the growing accumulation of field recordings in Africa that could form the nucleus for archives in individual African countries. These include private collections as well as recordings at broadcasting and television stations; government ministries such as Tourism, Culture and Information; museums and academic institutions. Sadly, these precious traditions – which have been expensively captured – are often not properly managed in their host institutions. The caretakers of this heritage mostly sit by as collections deteriorate and sometimes are disposed of due to lack of institutional support. Such practices prevail in most African archives. This paper proposes a new mode of consciousness of the value of audiovisual heritage materials by comparing them with human babies. This new archival management principle, ‘the baby nursing model’, has been adopted and practiced at the University of Ghana and has achieved positive results.

Published: April 2020

Background: Congestive cardiac failure (CCF) is often a worldwide phenomenon and usually affects millions of people years and is accompanied with high mortality. The present study is undertaken to evaluate the usefulness of Lung Ultrasound Scan in diagnosis and to identify its role as a marker of clinical outcome in patients with Acute LVF.Methods: A prospective analytical study was undertaken among the patients diagnosed as acute left ventricular failure who were admitted in tertiary care hospital. About 45 patients were enrolled by convenient sampling. The severity of acute LVF will be assessed using Clinical Congestion Score (CCS) and Lung Ultrasound Scan (LUS) based degree of congestion within 6 hours of admission, day 01 of admission and 24 hours before discharge.Results: The mean clinical congestion score was 5.36 at the time of admission. The Kerley B line at the time of admission was 15.93. The mean Kerley B line was 20.41 in the patients with clinical congestion score of more than 3.The mean Kerley B score after 24 hours of discharge was 19.69 and 5.69 during discharge among the patients with severe LV dysfunction. The mean Kerley B line score was higher at the time of admission which was statistically significant at the time of admission and within 24 hours after admission in patients with readmission.Conclusions: The mean clinical congestion scores and Kerley B lines were higher during the admission which rapidly decreased before discharge. There was a positive correlation between the Clinical congestion scores and Kerley B lines.

Cholinesterase activity in mixed saliva of patients with somatic pathology was investigated. The results showed differences in enzyme activity depending on the disease. The highest salivary cholinesterase activity was detected in patients with bronchopulmonary pathology, and the lowest - in cardiovascular diseases. A reliable relationship between the changes in the activity of cholinesterase in saliva and the rate of salivation, and with patients taking atypical antipsychotics and M, H-anticholinergic drugs, was revealed.

Considering a stage of the pathological process patients (boys at the age of 8-12 years) were divided into two (2) groups. Group I included 14 patients with the fragmentation stage (Perthes disease Stage II). Group 2 included 15 children with Perthes disease Stage III (the stage of re-ossification). Perthes disease regardless of the stage of the disease was characterized by the increase in oxygen-dependent and lysosomal phagocytic activity of neutrophils, the increase in the number of early extracellular traps, as well as by increased concentrations of pro-inflammatory cytokines (IL-1β and TNFa), IgE, decreased concentrations of IL-18. The fragmentation stage was characterized by moderate activation of cellular immunity with a prevailing increase in the number of T-lymphocytes with early activation markers (CD25). At the re-ossification stage the predominance of T-lymphocytes was observed with late activation markers (HLADR), being accompanied by moderate activation of humoral immunity (increased concentrations of class A and G serum immunoglobulins). The obtained data can be used as additional criteria for clarifying Perthes disease stage, predicting osteonecrosis development when making decision of the feasibility of performing reconstructive surgeries on the joint.

Escherichia coli is characterized by a wide intraspecific diversity. The species includes both commensals and pathogens that cause diarrhea and extra-intestinal diseases. Pathogenic strains differ from non-pathogenic ones by the presence of virulence factors and their genes. The phylogenetic structure of the species is represented by four main groups (A, B1, B2, D), which differ in their prevalence among residents of different geographical regions. Pathogenic members of the species have been studied in detail, while non-pathogenic strains have not received such attention. This report presents the results of a study of 511 E. coli strains isolated from the gut microbiota of children without diarrhea and urinary tract infections, aged from 1 month to 17 years, living in St. Petersburg. The main phylogenetic groups were determined by PCR, and E. coli virulence genes associated with diarrhea and extra-intestinal diseases were identified. Results: population structure of E. coli is represented by the following groups: A-33.3%, B1-6.7%, B2-34.0%, D-26%. In the studied population 2.5% of strains belonded to EPEC and 4.5% to EAggEC. EPEC virulence genes were more often detected in strains of phylogroup B1, and EAggEC virulence genes in isolates of phylogroup D. The prevalence of extra - intestinal virulence genes was as follows: pap - 29.5%; sfa - 19.8%; afa - 3.3%; hly - 20.9%; cnf - 17.4%; aer-20.0%. The pap, sfa, hly, and cnf genes were detected mostly in the B2 phylogenetic group. Obtained data shows the similarity of E. coli phylogenetic groups structure in St. Petersburg with E. coli populations isolated from residents of Paris and Sydney. Analysis of the virulence genes prevalence showed the dependence of their presence on the genetic background bacteria.

MiR-155 is involved in various physiological processes in the cell, including hematopoiesis, immunity, inflammation and differentiation. Increased expression of miR-155 is observed in many malignant diseases, including lymphomas, acute myeloid leukemia and CLL. However, a comparative study of the miR-155 expression in the blood leukocytes in patients with chronic myeloid and lymphoproliferative diseases has not yet been carried out. To investigate the expression of miR-155 in the blood cells of patients with lympho- and ph-negative myeloproliferative neoplasms. MiR-155 expression were studied in the blood leukocytes of 28 patients with B-CLL, 52 patients with MPN and 51 donors by “real time” PCR method. The study revealed an increase in miR-155 in blood leukocytes in both patients with CLL and patients with MPN compared with the control group. In accordance with the results of the ROC analysis, the sensitivity and specificity of blood leukocytes testing on miR-155 expression level was 81.8% and 78.4%, respectively, for CLL and 55.1% and 82.4%, respectively, for MPN. At the same time, in patients with CLL who received therapy, the level of miR-155 was significantly lower compared with those who did not receive therapy. Thus, the involvement of miR-155 in the pathogenesis of chronic myeloid and lymphoproliferative diseases was demonstrated.

De la diversión a la transformación. Movilidad de creencias mediante metodología Lego® Serious Play®
Authors: Gutiérrez Rivera Pablo , Gómez Nocetti Viviana
Published: April 2020

Este estudio reporta resultados de una experiencia de movilidad de creencias en formación inicial docente sobre escuelas en contextos de bajo nivel socioeconómico. Se implementaron cuatro sesiones basadas en la metodología Lego® SeriousPlay® (LSP) con un grupo de cuatro estudiantes novatos más dos grupos de tensionadores (estudiantes mayores y formadores), seleccionados mediante un instrumento sobre creencias epistemológicas y pobreza. Mediante análisis del discurso se establecieron las creencias relativas a escuelas vulnerables, estudiantes y profesores y luego se posicionaron en una gradiente de ingenuidad-sofisticación. Los resultados muestran que las primeras metáforas corroboran las creencias ingenuas en los estudiantes novatos, pero revelan menor sofisticación en estudiantes mayores respecto al cuestionario. La progresión en las sesiones muestra una trayectoria de sofisticación intermedia frente a estudiantes mayores, pero más acentuada ante los formadores. Estos últimos son los que más impactan en la sofisticación de las creencias.
