Lei de Bases do Sistema Educativo (1986): Ruturas, continuidades, apropriações seletivas
Authors: Lima Licínio C. 
Published: October 2018

O artigo apresenta uma análise sociológica e política da reforma do sistema educativo iniciada em meados da década de 1980 em Portugal. Em 1986, o governo nomeou uma Comissão de Reforma do Sistema Educativo com o objetivo de preparar estudos e propostas legislativas. Naquele ano o parlamento aprovou a Lei de Bases do Sistema Educativo. Ambos os processos decorreram de forma paralela, apenas com articulações posteriores, por iniciativa daquela comissão. A lei fundamental da educação de 1986 resultou da Constituição democrática de 1976 e veio substituir a anterior lei de 1973, aprovada no final do regime autoritário e nunca regulamentada. Com base numa análise dos textos das constituições, dos projetos de lei apresentados no parlamento, das leis de 1973 e de 1986, bem como de outros documentos de política educativa, o autor reflete criticamente sobre as ruturas operadas pela lei de 1986 face à lei de 1973 e também sobre as continuidades que foi possível observar. Outras ruturas e continuidades são ainda destacadas entre a lei de 1986 e as agendas de política educativa e respetiva produção legislativa dos governos durante as últimas três décadas, confirmando a plasticidade daquela lei e as dificuldades políticas do parlamento para a substituir.

Published: October 2018

OBJECTIVE
To examine the relative importance of maternal preexisting type 1 diabetes (T1D), preexisting type 2 diabetes (T2D), and gestational diabetes mellitus (GDM) on risk of attention deficit/hyperactivity disorder (ADHD) in offspring.

RESEARCH DESIGN AND METHODS
This retrospective birth cohort study included 333,182 singletons born in 1995–2012 within Kaiser Permanente Southern California hospitals. Children were prospectively followed through electronic medical records from age 4 years. Relative risks of ADHD associated with diabetes exposures in utero were estimated by hazard ratios (HRs) using Cox regression with adjustment for potential confounders. For GDM, timing of exposure was evaluated by gestational age at diagnosis and severity was assessed by the need for antidiabetes medication treatment during pregnancy.

RESULTS
A total of 37,878 (11.4%) children were exposed to diabetes (522 exposed to T1D, 7,822 T2D, and 29,534 GDM). During a median of 4.9 years (interquartile range 2.2, 9.6) of follow-up after age 4 years, 17,415 (5.2%) children were diagnosed with ADHD. ADHD risk was not associated with GDM taken as a whole (P = 0.50) or with gestational age at GDM diagnosis (P = 0.16). However, the risk was significantly greater for the GDM requiring versus not requiring antidiabetes medications (P &lt; 0.001). Compared with children unexposed to diabetes, the adjusted HRs for ADHD in children were 1.57 (95% CI 1.09–2.25) for exposure to T1D, 1.43 (1.29–1.60) for T2D, 1.26 (1.14–1.41) for GDM requiring antidiabetes medications, and 0.93 (0.86–1.01) for GDM not requiring medications.

CONCLUSIONS
The hierarchy of risks suggests that severity of maternal diabetes (T1D vs. T2D vs. GDM requiring antidiabetes medications) influences the risk of ADHD in offspring of mothers with diabetes.

Determinación de cambio climático y su registro en los procesos de colmatación en las ciénagas continentales (VVM ejemplo de caso)
Authors: Villamizar Mateus Victor Alfonso , Cantillo Romero Janer Rafael 
Published: October 2018

En los sedimentos de fondo de las ciénagas del sur del departamento del Cesar es posible observar una serie de procesos que conllevan a la colmatación inminente de los cuerpos de agua en estos territorios del Magdalena y la ampliación de la película de agua en el territorio, la perdida de profundidad efectiva y por ende procesos de eutrofización de las aguas con todo lo que ello conlleva. La correlación de los sedimentos de fondo en las diferentes etapas de formación de las ciénagas Musanda, Doña Maria, Baquero y Sordo, han permitido recrear las etapas de colmatación y los procesos de aceleración de estos procesos al menos en la última centuria. Las variable de cambio climático global observadas y analizadas como temperatura, relacionado con el proxy 10Be, δ18 O y los cambios en el nivel del mar, genera como resultado los cuatro eventos correlacionables de los registros de LOI y la estratigrafía, se aprecian cambios drásticos como disminución o aumento de los picos de los registros de LOI, asimismo estos cambios son comparables con los de cambio climático global. Se deriva un primer periodo cálido a un frio seco bastante intenso, un aumento progresivo en la temperatura y leve en la humedad, y seguidamente un periodo con un descenso y accenso drástico en la temperatura para 1910, posteriormente un aumento progresivo en todas las variables.

Authors: Recio Colmenares Roxana , Gurubel Tún Kelly 
Published: October 2018

Los procesos biológicos para el tratamiento de agua residual son sistemas altamente no lineales que están sometidos a incertidumbres y perturbaciones externas, se ha creído ampliamente que los modelos que describen las reacciones bioquímicas y procesos de sedimentación son muy complejos y difíciles de manejar exactamente con fines de control. Por tal motivo se requieren estrategias avanzadas para la identificación, estimación de parámetros no medibles del proceso y control.En este trabajo se propone una red neuronal no lineal en tiempo discreto en presencia de perturbaciones externas y estimación de los estados dinámicos difíciles de medir en un proceso de digestión aerobia para tratamiento de agua residual. Se presentan resultados de estimación vía simulación, donde se demuestra que el modelo neuronal propuesto es eficiente para la estimación de las dinámicas de los estados en presencia de perturbaciones. Con este modelo neuronal será posible diseñar una estrategia de control para optimizar el rendimiento de la degradación de materia orgánica en un proceso de digestión aerobia usando técnicas de control óptimo y estimación neuronal.

Abstract
OBJECTIVE To develop and characterize flow cytometric assays for detecting IgG bound to canine erythrocytes and bone marrow erythroid precursors.
SAMPLE Blood samples from 20 healthy and 61 sick dogs with (n = 33) or without (28) immune-mediated hemolytic anemia (IMHA) and bone marrow samples from 14 healthy dogs.
PROCEDURES A flow cytometric assay for measurement of IgG on RBCs was developed, and appropriate positive control cells were generated. Analytic and diagnostic performance were characterized. The RBC IgG assay was then combined with density-gradient fractionation of aspirated bone marrow cells and a 2-color process to yield an assay for detecting IgG on nucleated RBCs (nRBCs). Cell sorting and cytologic examination confirmed target cell populations, and anti–dog erythrocyte antigen 1 (DEA1) blood-typing serum was used to generate IgG-positive nRBCs.
RESULTS Within- and between-run coefficients of variation for the RBC IgG assay were 0.1% to 13.9%, and > 90% of spiked IgG-positive RBCs were detected. Diagnostic sensitivity and specificity of the assay for detection of IMHA were 88% and 93%, respectively. Cytologic findings for sorted bone marrow fractions rich in early-, mid-, and late-stage nRBCs from 3 healthy dogs indicated 89% to 98% nRBC purity. After IgG coating with anti-DEA1 blood-typing serum, IgG was detected on nRBCs from DEA1-positive, but not DEA1-negative, healthy dogs.
CONCLUSIONS AND CLINICAL RELEVANCE The developed RBC IgG assay had favorable analytic and diagnostic performance for detection of IMHA in dogs and was successfully adapted to detect IgG on canine nRBCs of various maturation stages. The findings supported the presence of DEA1 on canine nRBCs.

Abstract
OBJECTIVE To evaluate the 3-D geometry of canine pelves and to characterize the long-term effects of juvenile pubic symphysiodesis (JPS) on pelvic geometry by comparing the pelvic configuration between littermates that did and did not undergo the procedure.
ANIMALS 24 Labrador Retriever, Golden Retriever, or Labrador Retriever–Golden Retriever crossbred service dogs from 13 litters.
PROCEDURES At 16 weeks old, puppies with a hip joint distraction index ≥ 0.5 were randomly assigned to undergo thermal JPS (n = 9), mechanical JPS (7), or a sham (control) surgical procedure (8). Ten years later, each dog underwent a CT scan of the pelvic region. Modeling software was used to create 3-D reconstructions from the CT scans, and various pelvic measurements were made and compared among the 3 treatments.
RESULTS Compared with the control treatment, thermal and mechanical JPS increased the hemipelvis acetabular angle by 4°, the acetabular angle of lateral opening by 5°, and the orientation of the medial acetabular wall in a transverse plane by 6°, which indicated that JPS increased dorsal femoral head coverage by the acetabulum. Both JPS procedures decreased the pelvic canal area by approximately 20% and acetabular inclination by 6° but did not alter acetabular retroversion.
CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that thermal and mechanical JPS were equally effective in altering the 3-D pelvic geometry of dogs. These findings may help guide future studies of alternatives for optimizing canine pelvic anatomy to minimize the risk of hip dysplasia and associated osteoarthritis.

Abstract

Introduction
The purpose of this study was to investigate the protective effect of hydrogen-rich saline (HRS) against liver ischaemia-reperfusion combined resection injury.

Material and Methods
Eighteen miniature pigs were randomly divided into three groups: a sham operated group (sham group, laparoscopic liver ischaemia-reperfusion combined resection injury group (IRI group), and a hydrogen-rich saline intervention group (IRI + HRS group). Samples of hepatic tissue and serum were collected at the time of reperfusion and then 3 h, 1 d, and 3 d post reperfusion. Liver function, oxidative stress, autophagy-related mRNA genes, and protein expression were evaluated. Changes in cell and tissue ultrastructure were examined by transmission electron microscopy.

Results
Compared with the sham group, the level of autophagy of hepatocytes increased in the IRI and IRI + HRS groups, corresponding to high oxidative stress and severe liver function injury. Liver function, antioxidant content, autophagy levels, and liver injury were improved after intervention with HRS in the IRI + HRS group compared with the IRI group.

Conclusion
Intervention with hydrogen-rich saline could exert a protective effect against liver ischaemia-reperfusion combined resection injury through the reduction of oxidative stress and hepatocyte autophagy.
