    BACKGROUND: Women with Human Papilloma Virus (HPV) persistence are characterized by high levels of IL-10 at cervix. We have determined whether polymorphisms of IL-10 gene promoter might be associated with increased risk of squamous intraepithelial cervical lesions (SICL) and whether exist significative differences of IL-10 mRNA expression at cervix and systemic and serum IL-10 protein between SICL cases and non-Cervical Lesions (NCL). METHODS: Peripheral blood samples from SICL (n = 204) and NCL (n = 166) were used to detect IL-10 promoter polymorphisms at loci -592A/C (rs1800872), -819C/T (rs1800871), -1082A/G (rs1800896), -1352A/G (rs1800893), by allelic discrimination and to evaluate serum IL-10 protein. Cervical epithelial scrapings from NCL and biopsies from SICLs were used for HPV-typing and to evaluate IL-10 mRNA expression level. The systemic and local IL-10 mRNA expression levels were measured by real time-PCR. Genotypic and allelic frequencies of the selected polymorphisms were analyzed by logistic regression, adjusting by age and HPV-genotype, to determine the association with SICL. RESULTS: No significant differences were found between genotype frequencies at loci −819, -1082, and −1352. Individuals carrying at least one copy of risk allele A of polymorphism −592 had a two-fold increased risk of developing SICL [adjusted odds ratio (OR), 2.02 (95% CI, 1.26-3.25), p = 0.003], compared to NCL. The IL-10 mRNA expression and serum IL-10 protein, were significantly higher in SICL cases (p < 0.01), being higher in patients carrying the risk allele A. CONCLUSIONS: The −592 polymorphism is associated with increased risk of SICL and can serve as a marker of genetic susceptibility to SICL among Mexican women. According to IL-10 levels found in SICL, IL-10 can be relevant factor for viral persistence and progression disease

    La integración del diseño con la vanguardia se observa natural, esto es, el diseño es una disciplina abductiva y la vanguardia persigue fines prospectivos, es decir, en ambos casos se trata de objetivos de posibilidad futura. De tal suerte, este libro, emanado de una parte de las ponencias rigurosamente arbitradas del Coloquio Internacional de Diseño 2016, está dividido en tres secciones o capítulos, a saber, el capítulo uno relacionado con la teoría y metodología para proyectos de diseño de vanguardia, el segundo sobre la tecnología, la innovación y la sostenibilidad de vanguardia de dichos proyectos, y finalmente el último capítulo, vinculado con la gestión estratégica de proyectos de vanguardia.La historia se forja de hechos e interpretaciones, de pasados construidos y de presentes en procesos constantes, estudiados en forma estricta por las ciencias. Por su parte, el futuro ostenta la posibilidad de ser indefinidamente planeado con base en las variopintas aproximaciones teóricas y empíricas que dan fundamento a este tipo de ciencia; éstas son denominadas prospectivas y sus bases vanguardias. Resulta importante señalar, que estas posibilidades sólo permiten tener una idea hipotética de lo que será la realidad y el mundo de vida de los seres vivos y su contexto, no obstante, se trata de la única manera racional que tiene el ser humano de prever ese futuro posible. Las distintas ciencias y disciplinas nos permiten construir históricamente estas posibilidades partiendo de datos, hechos, significados y un sinfín de informaciones que le dan cuerpo y sentido a tales posibilidades. En este sentido, la vanguardia, como base del conocimiento prospectivo, observa la necesidad de ser escrita, leída y discutida en los términos más estrictos con el fin de volver las predicciones más precisas. El diseño por su parte, es definido de manera sucinta como la disciplina proyectual estratégica y sistémica de la posibilidad, dirigida a procesos de significación utilitaria y simbólica para la comprensión –o interpretación– y modificación –o proyectación– de niveles de realidad (referentes y sujetos) desde diversos aparatos teóricos y empíricos –perspectivas disciplinarias–

    The present study analyzes the relationship between age, grades and socialization of students with special educational needs (NEEs) belonging to a telesecundary. In order to accomplish that the BAS-1 socialization battery (teachers), BAS-2 (parents) and BAS-3 (students) were used. And it was held in a telesecundary in San Francisco de Campeche, with a sample of 25 students with NEEs, 25 parents and/or guardians of these and three titular teachers in charge of one of each grades. The results were analyzed with statistical correlation test. As part of the results, significant correlations (p < .05 and p < .01) were found between most of the scales and dimensions in the version for teachers and only some in the other two version; at the same time, some significant correlations between the versions. Also, between the scales and dimensions of the socialization battery with age and grades, in both cases there is a greater number of correlations with the teachers’ version.O presente estudo consistiu em analisar a relação entre idade, séries e socialização de alunos com necessidades educacionais especiais (NEE) pertencentes a uma telecdaria.

    Poco se sabe sobre el impacto del sobrepeso y la obesidad en la calidad de vida (CV), casi siempre se asocia a enfermedades cr&oacute;nicas. El prop&oacute;sito del presente estudio fue evaluar los patrones de calidad de vida relacionada con la salud (CVRS) y algunos comportamientos de salud en relaci&oacute;n con el &iacute;ndice de masa corporal (IMC), en una muestra de trabajadores de la industria manufacturera en Jalisco, M&eacute;xico, que no contaban con alguna enfermedad manifiesta. Se utiliz&oacute; un dise&ntilde;o transversal con una muestra de 392 trabajadores de la industria manufacturera, 200 (51%) proceden de industrias peque&ntilde;as, 118 (30%) de la industria mediana y 74 (19%) de la industria grande. De los 392 trabajadores encuestados, la mayor&iacute;a era mujer (65.1%), soltera (72%), en su mayor parte trabajadoras de producci&oacute;n (91%); el decremento de la actividad f&iacute;sica, la disminuci&oacute;n de los componentes mentales del SF-36 y el incremento de la percepci&oacute;n de problemas de salud se ven relacionados con el incremento IMC, en ambos sexos, con una asociaci&oacute;n lineal significativa en el deterioro de la funci&oacute;n f&iacute;sica y la percepci&oacute;n de salud en mujeres en contaste con los hombre. En conclusi&oacute;n, existen comportamientos en salud, as&iacute; como un deterioro f&iacute;sico e incremento en la percepci&oacute;n de malestares de salud asociados al incremento de IMC en los trabajadores de la industria manufacturera, con diferencias significativas por g&eacute;nero.Little is known about the impact of overweight and obesity related quality of life (Qol)), almost always associated with chronic diseases. The purpose of this study was to evaluate the patterns health related quality of life (HRQoL) and some health behaviors in relation to body mass index (BMI) in a sample of manufacturing workers who did not have any overt disease. A cross-sectional study was used with a sample of 392 manufacturing workers, 200 (51%) come from small industries, 118 (30%) of the industry median and 74 (19%) of the largest industry. Of the 392 workers surveyed, most were female (65,1%), single (72%), for the most part of production workers (91%); the decrease in physical activity, decreased mental components of the SF-36 and the increase in the perception of health problems are related to increased BMI for both gender, with a significant linear association in the impaired function and perceived physical health in women told the men. Scores on the mental components of the SF-36 did not differ by BMI categories in both sexes. In conclusion, there are health behaviors and physical deterioration and increase in the perception of health ailments associated to increased BMI on workers in the manufacturing industry, with significant differences by gender

    Patients with endogenous hypercortisolism are prone to develop infectious diseases. In this study, we investigated the spontaneous and in vitro response to interleukin-2 (LAK) or interferon -a (IFN-a NK) natural  killer cytotoxicity in 12 ambulatory female patients with Cushing’s disease (CD) Twelve healthy age-matched women served as control subjects (C). Mean spontaneous NK activity in CD ( 1.82 ± 0.77 LU/106 PBL) was not different than C (2.38 ± 0.59 LU/106 PBL). Mean LAK activity in CD (4.27 ± 1.72 LU/106 PBL) was significantly lower than C (9.52 ± 1.19 LU/10 6 PBL; p<0.001). Mean IFN-a NK cytotoxicity response in CD (3.33 ± 1.57 LU/10 6 PBL) was significantly reduced compared with C (8.41 ± 1.24 LU/106 PBL, p< 0.001). Spontaneous and stimulated NK cytotoxicity did not show correlation with plasma corticotrophin, total urinary-free cortisol or late salivary cortisol. Although spontaneous NK cytotoxicity did not demonstrate differences from healthy women, this finding did not exclude an impairment of the NK response to immunomodulators like found in these high-risk patients.Fil: Cardoso, Estela M. del Luján.
