Los organismos defensores de los derechos universitarios en México, Una mirada desde la REDDU

El nacimiento de la universidad en Occidente se debió al reclamo y ejercicio de los que hoy denominamos derechos universitarios, protegidos por organismos llamados defensorías, procuradurías o comisiones. A pesar de su importante labor, éstos son poco conocidos en México. Este libro ofrece el estado actual de tales entidades, resultado del proyecto Diagnóstico de las Defensorías y Procuradurías de los Derechos Universitarios en las Universidades públicas estatales y federales en México. Dicha investigación se ha enriquecido mediante la incorporación de instituciones pertenecientes a la Red de Organismos Defensores de los Derechos Universitarios (REDDU).Universidad Autónoma del Estado de México

CONTROLE ESTRUTURAL DO NEÓGENO E QUATERNÁRIO NAS BACIAS DE CAMPOS E DO ESPÍRITO SANTO

A principal produção de hidrocarbonetos nas bacias de Campos e do Espírito Santo é associada a reservatórios turbidíticos do Cenozoico, sendo na sua maioria de idade oligo-miocênica. Interpretações sísmicas realizadas, apontam a presença de armadilhas mistas (estruturais–estratigráficas), cujo componente estrutural seria de idade neógena a quaternária. O objetivo deste trabalho consiste na identificação, caracterização e interpretação das estruturas tectônicas do Neógeno e Quaternário presentes na porção offshore destas bacias, utilizando interpretação sísmica integrada com métodos potenciais. O intuito é caracterizar a importância da deformação tectônica, deste período, nos processos que confinam a jazida, e definir possíveis províncias que poderiam conter plays exploratórios específicos. As análises foram realizadas com base na interpretação de dados geofísicos (sísmicos, de poços e métodos potenciais) controlados pelo refletor do Mioceno Médio e a deformação associada a este. Como resultado, sete províncias de hidrocarboneto foram identificadas limitadas, principalmente, por sistemas de falhas com projeção lateral no embasamento aflorante e por falhas neotectônicas reativadas de estruturas geológicas pré-existentes

Lightning Activity Over Chilean Territory

This work presents the spatial distribution and temporal variability of lightning activity over the continental territory of Chile by means of Thunderstorms days (Td), on the basis of 7 years (2012–2018) of lightning measurement from World Wide Lightning Location Network (WWLLN). Td are obtained separately for the 15 geopolitical regions of Chile, reporting the higher lightning activity in the northeastern region of the country with 85 thunderstorms days per year. These values are mainly located in the mountains between 2,000 and 5,000 m.a.s.l. where extensive mining activity is located and there are electrical facilities of great importance for Chile. The Td values obtained in this study update the information presented by the World Meteorological Organization (WMO) in 1953, so far the only one available for the entire Chilean territory. From the diurnal cycle analysis, there is a marked mono-modal behavior of lightning activity in the afternoon for latitudes between (Formula presented.) S and (Formula presented.) S (regions XV, I, and II) and a different behavior of lightning activity over the region between (Formula presented.) S and (Formula presented.) S (regions X, XI, and XII) known as Chilean Patagonia, due to special weather conditions in that area. Further more, the seasonal analysis showed that the highest lightning activity occurs in January and February and the lowest activity takes place between June and August. Once again, the Chilean Patagonia showed a different behavior because the highest activity is presented in May and August, and the lowest in September. The analysis and results presented here contribute to the knowledge of lightning activity in the region that has not been characterized before and can serve as a basis for future research to determine the behavior of this natural phenomenon.Fil: Montana, Johny.

State biomarkers for Machado Joseph disease : validation, feasibility and responsiveness to change

Machado-Joseph disease (SCA3/MJD) is the most common spinocerebellar ataxia worldwide, and particularly so in Southern Brazil. Due to an expanded polyglutamine at ataxin-3, SCA3/MJD presents a relentless course with no current disease modifying treatment. Clinical scales used to measure SCA3/MJD progression present moderate effect sizes, a major drawback for their use as main outcomes in clinical trials, given the rarity and slow progression of the disease. This limitation might be overcome by finding good surrogate markers. We present here a review of studies on peripheral and neurophysiological markers in SCA3/MJD that can be candidates for state biomarkers. Data on markers already studied were summarized, giving emphasis on validation against clinical scale, and responsiveness to change. While some biological fluid compounds and neurophysiological parameters showed poor responsiveness, others seemed to be good candidates. Some potential candidates that are waiting for responsiveness studies were serum levels of neuron specific enolase, vestibulo-ocular reflex and video-oculography. Candidates evaluated by RNA and microRNA expression levels need further studies to improve their measurements. Data on peripheral levels of Beclin-1 and DNAJB1 are promising but still incipient. We conclude that several potential candidates should follow onto validating studies for surrogate state biomarkers of SCA3/MJD

Biofertilization of topinambur with Azospirillum brasilense and native mycorrhical fungi, cultivated in the Central Valley of Catamarca, Argentina

To evaluate the effect of Azospirillum and mycorrhizal soil fungi on the nutrition of the Jerusalem artichoke crop (Helianthus tuberosus L.), determinations of agronomic parameters and the health status of the plants were carried out under field conditions. The tests were carried out, at the time of the implantation of the culture: the ?seeds? were inoculated with A. brasilense and with native mycorrhizal fungi, generating four treatments including the control and the co-inoculation of the consortium of the microorganisms under study (T0: control or uninoculated control; T1: inoculation with native A. brasilense; T2: inoculation with native mycorrhizal fungi and T3: joint inoculation with A. brasilense and native mycorrhizal fungi). The results indicate that co-inoculation with A. brasilense and native mycorrhizal fungi, significantly increased plant growth in height, leaf area, biomass, dry matter, and yields. It was determined that the application of the selected microorganisms has a promoting effect of plant growth, increasing the growth and productivity of the topinambur crop.Fil: Di Barbaro, Maria Gabriela.

Effect of Azospirillum brasilense and mycorrhizal soil fungi on topinambur grown in a greenhouse

To determine the effect of Azospirillum brasilense and soil mycorrhizal fungi on the nutrition of the Jerusalem artichoke crop (Helianthus tuberosus L.), evaluations of agronomic parameters and the health status of the plants were carried out, under greenhouse conditions. The tests were carried out, at the moment of the implantation of the culture: the tubers were inoculated with A. brasilense and with native mycorrhizal fungi, generating four treatments including the control and the co-inoculation of the consortium of the microorganisms under study (T0: control or control without inoculation; T1: inoculation with native A. brasilense; T2: inoculation with native mycorrhizal fungi and T3: joint inoculation with A. brasilense and native mycorrhizal fungi. The results indicate that co-inoculation with A. brasilense and with native mycorrhizal fungi increased plant growth in height, leaf area, biomass, dry matter, and yields significantly in greenhouse production. It was determined that the application of the selected microorganisms has a plant growth-promoting effect, increasing the productivity of cultivated topinambur in the greenhouse.Fil: Di Barbaro, Maria Gabriela.

Pretreatment of Real Wastewater from the Chocolate Manufacturing Industry through an Integrated Process of Electrocoagulation and Sand Filtration

En este artículo se analizó el efecto de un proceso acoplado de electrocoagulación y filtración, para remover partículas suspendidas en un agua residual procedente de una industria de chocolates.The purpose of this study was to evaluate the efficiency of removal of suspended solids in terms of turbidity, color, and chemical oxygen demand (COD) when integrating the electrocoagulation process using aluminum sacrificial anodes and the sand filtration process as a pretreatment of wastewater from the chocolate manufacturing plant in Toluca, México. Wastewater from the chocolate manufacturing industry used in this study is classified as nontoxic, but is characterized as having a high content of color (5952 ± 76 Pt-Co), turbidity (1648 ± 49 FAU), and COD (3608 ± 250 mg/L). Therefore, enhanced performance could be achieved by combining pretreatment techniques to increase the efficiencies of the physical, chemical, and biological treatments. In the integrated process, there was a turbidity reduction of 96.1 ± 0.2% and an increase in dissolved oxygen from 3.8 ± 0.05 mg/L (inlet sand filtration) to 6.05 ± 0.03 mg/L (outlet sand filtration) after 120 min of treatment. These results indicate good water quality necessary for all forms of elemental life. Color and COD removals were 98.2 ± 0.2% and 39.02 ± 2.2%, respectively, during the electrocoagulation process (0.2915 mA/cm2 current density and 120 min of treatment). The proposed integrated process could be an attractive alternative of pretreatment of real wastewater to increase water quality of conventional treatments

The adiponectin/leptin ratio is a useful tool to evaluate de metabolic status in an Obstetrical Intensive Care Unit

Introduction. Critically ill patients, including obstetrical patients, face undernutrition but a reliable and cost effective study to assess their nutritional state is still missing. Our main objective was to analyze serum leptin and adiponectin concentrations in puerperal women attended in an Obstetrical Intensive Care Unit (OICU) in order to evaluate their potential role as nutritional metabolic parameter. Methods. This was a descriptive, clinical, longitudinal and comparative study. We evaluated the anthropometric variables, clinical laboratories, daily calories and adiponectin and leptin serum levels of 16 puerperal women attended at the OICU of the Materno Perinatal Hospital “Mónica Pretelini” (HMPMP). Results. For all women there was a negative correlation with Spearman test between leptin the day of discharge from the obstetrical intensive care unit and the days of stay –0.632 (p = 0.011). Considering an adiponectin/leptin ratio, the media in the first day was of 0.3 (0.07–13.6) and in the day of discharge it was of 2.4 (0.1–24.6) in overweight women. The same values for obese women were of 0.3 (0.2–0.4) and 0.5 (0.3–1.2). Conclusion. After an average of six days of hospitalization, leptin showed a decrement in women attended at the OICU. As expected, adiponectin increased in both groups. The adiponectin/leptin ratio could be a useful metabolic parameter

Arboviruses emerging in Peru: need for early detection of febrile syndrome during El Niño episodes

The presence of El Niño Southern Oscillation (ENSO) implies the presence of fluctuating rains in coastal areas and these changes influence the occurrence of febrile syndromes outbreaks. In Peru, Aedes aegypti is the vector responsible for various viruses such as the dengue, Zika, chikungunya, which is distributed in 18 Peruvian departments. These viruses cause similar clinical characteristics in the host and for this reason rapid, sensitive and specific diagnostic tests are needed so that the patient can receive timely treatment.Revisión por pare

PL-016 Endurance training, muscle fibre type composition and the maximal capacity for fat oxidation

Objective A greater capacity for fat oxidation in endurance trained athletes is linked to greater utilisation of intramuscular lipid (IMCL). IMCL breakdown occurs only in type I muscle fibres yet little is known about the fibre type specific abundance of lipid regulatory proteins. We explored the impact of endurance training on the maximal rate fat oxidation, muscle fibre type and muscle fibre type specific abundance of proteins regulating IMCL metabolism. Methods Endurance trained (n=7, 28 ± 3 years, VO2max62.6 ± 1.6 ml·min-1·kg-1) and untrained (n=8, 25 ± 1 years, VO2max44.9 ± 1.9 ml·min-1·kg-1) males performed an incremental exercise test to determine maximal fat oxidation rate. Muscle fibre type composition and fibre type-specific IMCL content was assessed with immunofluorescence microscopy and protein abundance was analysed with immunoblotting on pooled single muscle fibres and whole muscle. Results Endurance trained individuals displayed a higher peak fat oxidation rate (0.49 ± 0.05 vs. 0.20 ± 0.03 g·min-1, P<0.05), which correlated with type I fibre percentage (R = 0.83, P < 0.01) and VO2max (R = 0.78, P < 0.01). Type I muscle fibres from endurance trained individuals had a greater abundance of ATGL. In whole muscle, the endurance trained group had greater abundance of PLIN2, PLIN5 and ATGL compared to the untrained group (P < 0.05). Furthermore, autophagy flux measured as LC3-II/I ratio was higher in type I muscle fibres and LC3-II/I, lysosomal markers (LAMP2) and chaperone-mediated autophagy markers (LAMP2A) were all higher in whole muscle of endurance trained individuals (P < 0.05). Conclusions These results demonstrate that the maximal rate of fat oxidation is related to the proportion of type I muscle fibres. Furthermore, IMCL storage and the abundance of key proteins regulating lipid metabolism is fibre type specific and greater in endurance trained individuals. Muscle fibre type composition should be considered when investigating the regulation of IMCL utilisation and markers of autophagy
