Yo ayudo, tú ayudas ¡y cómo nos ayudamos! Espacio de autoconocimiento y escucha

En este trabajo se da cuenta de la experiencia durante el grupo/taller denominado “Yo ayudo, tu ayudas ¡y cómo nos ayudamos! Espacio de autoconocimiento y escucha de los colaboradores de un Centro de Rehabilitación Integral”. Se detalla lo sucedido desde su planeación, las modificaciones y adaptaciones que se requirieron durante el proceso, hasta las conclusiones y el resultado del análisis del material obtenido durante esta experiencia. El lector encontrará una parte de la realidad de las once colaboradoras del Centro de Rehabilitación. Será un acercamiento a los sentimientos, emociones y sensaciones que acompañan la labor de quienes ayudan todos los días a personas con discapacidad y las historias personales de la vida privada que les acompaña, ese espacio que, como diría Luis Carlos Restrepo (1994), es donde se entreteje lo público. Se muestra el proceso vivido durante los talleres de intervención, donde hubo un acercamiento persona a persona con cada uno de los participantes. A lo largo del trabajo se podrá reconocer cómo, sesión a sesión, se aprendieron herramientas que facilitaron el autoconocimiento, autocuidado y un modo de estar más presentes para cada una de las personas que trabajan en el Centro, para el equipo de trabajadoras y para los pacientes. También encontrará, a la par de los resultados del grupo/taller, algunos de los avances o estudios que se han hecho sobre el tema, desde trabajos de grado de la Maestría en Desarrollo Humano del ITESO e IBERO sobre el desgaste del voluntariado en temas de salud y el autoconocimiento, así como investigaciones o artículos de otros países que complementan y van de la mano con el sustento teórico de los autores que ayudaron a fundamentar el taller, análisis y construcción de las conclusiones. El eje central de este documento es el Enfoque Centrado en la Persona de Carl Rogers y el Focusing de Eugene Gendlin.ITESO, A. C

Las estrategias utilizadas por los niños Tee Savi en la resolución de problemas aritméticos

En: Revista Latinoamericana de Investigación en Matemática Educativa, Vol. 18; No. 2, pp. 213-244. doi: 10.12802/relime.13.1823México es un país con una gran diversidad cultural y lingüística, por esta razón y por la importancia que ha cobrado la interculturalidad planteada en los planes y programas de estudio en vigor para la educación pública (SEP, 2011a), es que nos interesamos en una comunidad particular, la población de niños Tee Savi (mixtecos). Específicamente nos cuestionamos sobre cuáles son las estrategias que utilizan los niños Tee Savi de primaria cuando resuelven problemas aritméticos formales y prácticos. Identificar las estrategias utilizadas permite, entre otros resultados, comparar su eficiencia en la resolución de los problemas antes mencionados. Como método de investigación se utilizó el estudio de casos múltiples, donde participaron 70 alumnos de 4°, 5° y 6° grado de primaria, cuyas edades oscilan entre los 9 y los 13 años. Se recurrió a cuestionarios (escritos en español) y entrevistas grupales (en Tu’un Savi, lengua materna del alumno) como instrumentos de recolección de datos. Las evidencias escritas y orales dan cuenta de la diferencia entre las estrategias usadas para ambos tipos de problemas

Impact of neurodegenerative diseases on human adult hippocampal neurogenesis

Disrupted hippocampal performance underlies psychiatric comorbidities and cognitive impairments in patients with neurodegenerative disorders. To understand the contribution of adult hippocampal neurogenesis (AHN) to amyotrophic lateral sclerosis, Huntington's disease, Parkinson's disease, dementia with Lewy bodies, and frontotemporal dementia, we studied postmortem human samples. We found that adult-born dentate granule cells showed abnormal morphological development and changes in the expression of differentiation markers. The ratio of quiescent to proliferating hippocampal neural stem cells shifted, and the homeostasis of the neurogenic niche was altered. Aging and neurodegenerative diseases reduced the phagocytic capacity of microglia, triggered astrogliosis, and altered the microvasculature of the dentate gyrus. Thus, enhanced vulnerability of AHN to neurodegeneration might underlie hippocampal dysfunction during physiological and pathological aging in humans.Fil: Terreros Roncal, J..

Unusual presentation of hepatitis B serological markers in an Amerindian community of Venezuela with a majority of occult cases

<p>Abstract</p> <p>Background</p> <p>Occult hepatitis B infection (OBI) is characterized by the presence of hepatitis B virus (HBV) DNA in the absence of HBsAg in the serum of patients. The aim of this study was to characterize HBV infection among a Piaroa community, an Amerindian group which exhibits significant evidence of exposure to HBV but relatively low presence of HBsAg, and to explore the presence of OBI in this population.</p> <p>Results</p> <p>Of 150 sera, with 17% anti-HBc and 1.3% HBsAg prevalence, 70 were tested for the presence of HBV DNA. From these, 25 (36%) were found positive for HBV DNA by PCR in the core region. Two of these 25 sera were HBsAg positive, indicating an overt infection. Of the remaining 68 sera tested, 23 exhibited OBI. Of these, 13 were HBV DNA out of 25 anti-HBc positive (52%) and 10 HBV DNA positive, out of 43 anti-HBc negative (23%), with a statistical significance of <it>p </it>= 0.03. Viral DNA and HBsAg were present intermittently in follow up sera of 13 individuals. Sequence analysis in the core region of the amplified DNA products showed that all the strains belonged to HBV genotype F3. The OBI isolates displayed 96-100% nucleotide identity between them. One isolate exhibited the co-circulation of a wild type variant with a variant with a premature stop codon at the core protein, and a variant exhibiting a deletion of 28 amino acids.</p> <p>Conclusions</p> <p>The frequency of OBI found in this Amerindian group warrants further studies in other communities exhibiting different degrees of HBV exposure.</p

Assessment of a surface-active ionic liquid formulation for EOR applications: Experimental and simulation studies

This study aims to assess a surfactant blend for enhanced oil recovery from carbonate rocks. Due to the abundance of these reservoirs, their profitable exploitation would ensure our petrochemical needs are met, and maintain current quality of life. The objective of this work is to increase the technology readiness level of our previous proposal based on the use of a blend of pure sodium dodecylbenzene sulfonate and the surface-active ionic liquid cocosalkylpentaethoximethyl ammonium methylsulfate. To that aim, the method was adapted for its application with a commercially available petrochemical surfactant (RECOLAS103, a mixture of lineal alkyl benzene sulfonates), and reservoir simulations were carried out to evaluate its effectiveness. Phase behavior, stability, dynamic interfacial tension, adsorption and core flooding were the experimental tests carried out. An optimized formulation consisting of 1 wt% of blend (40 wt% RECOLAS103) in synthetic sea water was found stable and able to reduce water-oil interfacial tension down to 0.02 mN/m. The dynamic blend adsorption in carbonate rocks was found to be 0.60 mg/grock, a promising value for the application. Core flooding tests were conducted at 25 and 120 °C and additional oil recoveries achieved ranged from 10.2 to 12.7% of the original oil in place, the lowest production obtained at the highest temperature. This work offers an advance in the application of surfactants for EOR in carbonate reservoirs, since it improves previous proposals that show stability or high adsorption problems. Moreover, a chemical injection optimization was also carried out by simulation with the CMG-STARS software. Results point to the possibility of reaching higher oil recoveries than those obtained experimentally if the extraction method is optimizedS

Prognostic Factors in Patients with Rocky Mountain Spotted Fever

Background: Rocky Mountain Spotted Fever (RMSF) is a disease with a high mortality rate, caused by Rickettsia rickettsii, a bacteria transmitted to humans by infected ticks. In 2008 there was a Rocky Mountain Spotted Fever (RMSF) outbreak in the city of Mexicali, México, resulting in an increased mortality rate amongst the area population. Methods: Case-series study of patients admitted to the General Hospital of Mexicali between 2014 and 2019 with a confirmed diagnosis of RMSF. Mortality was compared dividing the population on those ?20 and younger than ?21 years of age. Results: A total of 129 patients’ records during a 5-year period whose diagnosis was RMSF confirmed with PCR were included. Mortality was compared among patients admitted who were younger than ?20 years of age with that among patients who were older than ?20 years of age (61 versus 68 respectively), the latter being higher with an OR 4.2 (p&lt;0.0001). Conclusion: RMSF in hospitalized patients has a high mortality rate in spite of early treatment in all age groups, without showing any predominance in gender. However, patients older than 20 years of age had a higher mortality rate than those younger than 20 years, without any predominance in gender

Psychosocial profile of juvenile and adult offenders who acknowledge having committed child-to-parent violence

The main objective of this study was to establish the psychosocial profile of adolescents and adults who have admitted to committing child-to-parent violence (CPV) and were serving a judicial sanction or prison sentence, respectively. Two groups of participants took part in this study. The first group was made up of 89 male youths who were serving judicial sanctions, and the second group was made up of 70 men serving a prison sentence. A cross-sectional retrospective design with concurrent measurements was used in this study. Group differences in the exposure-to-violence variables were conducted. Automatic regression models were used to estimate a self-reported CPV. In relation to the variables of indirect exposure to violence, statistically significant differences between those who admitted having committed CPV and those who did not, irrespective of being adults or adolescents, were found for seeing violence in class and at home but not for seeing violence on the street or on television. Regarding the variables related to experiencing violence, the results showed statistically significant differences in experiencing violence at home but not in class or on the street. The best predictive model of CPV includes some of the dimensions of self-concept, specifically academic and family self-concept, as well as the avoidant and rational problem-solving styles and the negative orientation toward problems. The results have shown the existence of a CPV offender profile that is common to minors and adults

Non-conventional yeasts as hosts for heterologous protein production

Creative Commons-Attribution-Non-Commercial-Share Alike 3.0 Spain.-- et al.Yeasts are an attractive group of lower eukaryotic microorganisms, some of which are used in several industrial processes that include brewing, baking and the production of a variety of biochemical compounds. More recently, yeasts have been developed as host organisms for the production of foreign (heterologous) proteins. Saccharomyces ccrevisiae has usually been the yeast of choice, but an increasing number of alternative non-Saccharomyces yeasts has now become accessible for modern molecular genetics techniques. Some of them exhibit certain favourable traits such as high-level secretion or very strong and tightly regulated promoters, offering significant advantages over traditional bakers' yeast. In the present work, the current status of Kluyveromyces lactis, Yarrowia lipolytica, Hansennla polymorpha and Picliia pastoris (the best-known alternative yeast systems) is reviewed. The advantages and limitations of these systems are discussed in relation to S. cerevisiae. © Springer-Verlag 1998.This work was partially supported by grants from the CICYT (BIO92-0304 and BIO 95-0518) and EU (BIO4-CT96-0003).Peer Reviewe
