Sobre la revolución territorial de los pueblos. Diputación provincial y ayuntamientos en Guanajuato, 1822-1824

Abstract: This article focuses on the history of the diputación provincial in Guanajuato. During the 25 months that it functioned as an institution, the principle objective of the representatives (diputados) on that provincial board (junta) was to achieve a transformation that would make it the dominant instance in political and administrative government in Guanajuato. What institutional performance allowed it to occupy the territorial hierarchy in Guanajuato? With whom was it allied? What social and economic processes facilitated or impeded the board's work? To answer these questions, the essay examines -and adds many lines of research that question- the pertinence of using the historiographic concept of the "territorial revolution of peoples" proposed by Antonio Annino as a way to understand the political transition from New Spain to 19th-century Mexico.Resumen: En este artículo me centro en la historia de la diputación provincial de Guanajuato. En estos años y un mes de funcionamiento institucional, los diputados de la junta provincial tuvieron como principal objetivo convertirse en la instancia que dominaba el gobierno político y administrativo de Guanajuato. ¿Cuál fue el desempeño institucional que les permitió ocupar la jerarquía territorial de Guanajuato?, ¿con quiénes se aliaron?, ¿qué procesos sociales y económicos facilitaron o impidieron la labor de la junta? Para responder a esas preguntas, en este artículo retomo y agrego muchas más líneas de investigación que cuestionan la pertinencia de usar el concepto historiográfico de la "revolución territorial de los pueblos" propuesto por Antonio Annino, a fin de entender la transición política entre la Nueva España y el México decimonónico

Analysis of the objective internal load in Portuguese skydivers in the first jump of the day

The general objective of this study was to identify the variation in heart rate (HR) of Portuguese skydivers during 6 moments in their first jump of the day, bearing in mind the variable level of experience. Thirty-one Portuguese skydivers, 28 men and 3 women, aged between 19 and 62, participated in the study, 12 had A and B licenses (less experienced) and 19 had C and D licences (more experienced). The instrument used to record the heart rate of the skydivers at the different moments of their first jump of the day was the WIMU PRO. A repeated measures analysis of variance was used to analyse HR at different moments in the jump and its relation with the variables level of experience. Bonferroni multiple comparisons were performed to study the importance of the differences observed in HR at the different moments. The effect size was evaluated with partial eta squared. The results showed that average HR in this group of skydivers was 130 bpm, in the different moments of the jump. HR increases from the value recorded at rest until the moment of jumping from the plane and opening the parachute, reaching the highest average at that moment, then decreasing until contact with the ground. Comparing the variable, we found that the less experienced had higher HR than the more experienced at all moments during the jump. Statistically significant differences were found at the different moments of the jump, regarding HR (Max: p < 0.001, η 2 p = 0.820; Min: p < 0.001, η 2 p = 0.821; AVG: p < 0.001, η 2 p = 0.834) Level of experience with jumping moment interaction, we only verified differences related to HR Min (p = 0.007, η 2 p = 0.056),. With regard to experience, the identified differences were not statistically significant. Skydiving triggers an acute adaptive cardiovascular response which is reflected in the increase in the HR, between the moment of boarding the plane and the moment at which the parachute opens, thereafter decreasing until contact with the ground. The most experienced parachutists recorded the highest HR at the moment of landing and the least experienced at the moment of free fall.info:eu-repo/semantics/publishedVersio

Demonstrating engineering schools’ commitment to the achievement of the SDGs: The ALCAEUS Evaluation Program / 2030 Agenda. A case study

ALCAEUS is a voluntary evaluation scheme developed by the Spanish agency ACPUA, designed to provide visibility to institutions and centers that demonstrate commitment and contribute to the achievement of the UN Sustainable Development Goals (SDGs) / 2030 Agenda. It is a pioneering international external evaluation program within the European Higher Education Area, open to faculties and schools that have successfully undergone an IQAS certification review (institutional accreditation). The ALCAEUS pilot program was carried out last year and two Engineering Schools (Escuela de Ingeniería y Arquitectura and Escuela Politécnica Superior) of the University of Zaragoza (Spain) participated in it. The evaluation was based on a site visit conducted by an international review team. The two schools demonstrated a firm commitment to SDGs and were awarded a 2030 Agenda quality label valid for 6 years

Prognostic value of RT-PCR tyrosinase detection in peripheral blood of melanoma patients

Malignant melanoma (MM) prognosis has been related to tumour thickness and clinical stage and metastasis risk has been associated with presence of tumour cells in peripheral blood. The aim of this study was to determine the relationship between presence of tyrosinase in peripheral blood of MM patients and their clinical prognosis. Blood samples from 58 MM patients (stage I–IV) were analysed, using RT-PCR assay to detect tyrosinase mRNA. The results showed that positive RT-PCR assay for tyrosinase were significantly associated with clinical status and tumour thickness. After a median follow-up of 24 months, RT-PCR results were found to be significant correlated with recurrence (p < 0.05) and clinical stage III (p < 0.05). Separate analysis of stage III tumours to determine the prognostic value of tyrosinase presence in peripheral blood showed an overall 24-month survival rate of 70% in the RT-PCR negative group versus 10% in the positive group (p < 0.02). These results suggest that detection of circulating melanoma cells may be especially relevant in stage III patients, in whom RT-PCR positivity defines a subpopulation at high risk of recurrence.This study was supported by the Fondo de Investigación Sanitaria de la Seguridad Social (FIS), Spain through no.

Study of antitumor activity in breast cell lines using silver nanoparticles produced by yeast

In the present article, we describe a study of antitumor activity in breast cell lines using silver nanoparticles (Ag NPs) synthesized by a microbiological method. These Ag NPs were tested for their antitumor activity against MCF7 and T47D cancer cells and MCF10-A normal breast cell line. We analyzed cell viability, apoptosis induction, and endocytosis activity of those cell lines and we observed that the effects of the biosynthesized Ag NPs were directly related with the endocytosis activity. Moreover, Ag NPs had higher inhibition efficacy in tumor lines than in normal lines of breast cells, which is due to the higher endocytic activity of tumor cells compared to normal cells. In this way, we demonstrate that biosynthesized Ag NPs can be an alternative for the treatment of tumors.Support from Universidad Nacional de San Luis, to the Agencia Nacional de Promoción Científica y Tecnológica, from Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) (Argentina), and from GENYO, Centre for Genomics and Oncological Research: Pfizer-University of Granada, Andalusian Regional Government, Granada, Spain are acknowledged

Concurrent Validity and Reliability of Devices to Measure Jump Height in Men’s Handball Players

Although there is a wide range of validated devices to measure vertical jump height, the degree of interchangeability among them is currently unknown. Aims: The purpose of this study was to examine the concurrent validity and reliability of multiple devices to measure jump height in men’s handball players. Methods: Sixteen players (age = 24.0 ± 3.7 years old) performed three types of jumps (n= 144—squat jump (SJ), countermovement jump (CMJ) and Abalakov jump (ABK)) on a contact platform (CHRONOJUMP®) while simultaneously being measured with two inertial devices (WIMU® and VERT®) and recorded with a high-speed camera. Vertical jump height was analyzed according to each type of jump. Results: The t-test showed statistically significant differences (p = 0.001) between the contact platform (reference standard) and the rest of the tools that tended to overestimate jump height in all jumps. SJ and CMJ proved to be the jump tests with the most stable reliability values in all devices (ICC: 0.92–0.98), except in the comparison with VERT®. Conclusions: Although all the analyzed devices proved to be valid and reliable in previous studies, they are not interchangeable. Therefore, it is suggested to always use the same type of device to evaluate vertical height jump

A Novel, Quick, and Reliable Smartphone-Based Method for Serum PSA Quantification: Original Design of a Portable Microfluidic Immunosensor-Based System

We describe a versatile, portable, and simple platform that includes a microfluidic electrochemical immunosensor for prostate-specific antigen (PSA) detection. It is based on the covalent immobilization of the anti-PSA monoclonal antibody on magnetic microbeads retained in the central channel of a microfluidic device. Image flow cytometry and scanning electron microscopy were used to characterize the magnetic microbeads. A direct sandwich immunoassay (with horseradish peroxidase-conjugated PSA antibody) served to quantify the cancer biomarker in serum samples. The enzymatic product was detected at -100 mV by amperometry on sputtered thin-film electrodes. Electrochemical reaction produced a current proportional to the PSA level, with a linear range from 10 pg mL(-1) to 1500 pg mL(-1). The sensitivity was demonstrated by a detection limit of 2 pg mL(-1) and the reproducibility by a coefficient of variation of 6.16%. The clinical performance of this platform was tested in serum samples from patients with prostate cancer (PCa), observing high specificity and full correlation with gold standard determinations. In conclusion, this analytical platform is a promising tool for measuring PSA levels in patients with PCa, offering a high sensitivity and reduced variability. The small platform size and low cost of this quantitative methodology support its suitability for the fast and sensitive analysis of PSA and other circulating biomarkers in patients. Further research is warranted to verify these findings and explore its potential application at all healthcare levels.Universidad Nacional de San Luis PROICO 22/Q241ANPCyT PICT 2018-04443 PICT-2015-2246 PICT-2015-1575 PICT-2014-1184 PICT-2014-0375 PICT-2018-04443Consejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET) PIP 11220150100004COGENYOCentre for Genomics and Oncological Research: Pfizer-University of GranadaAndalusian Regional Government (Granada, Spain)ISCIII Health Research Institute P17/00989La Caixa FoundationHealth and Family Secretariat of the Andalusian Regional GovernmentSpanish GovernmentH2020-MSCA-IF-2019-89566

Galanin n-terminal fragment (1-15) decreases the voluntary alcohol intake in rats

Galanin (GAL) is involved in drug abuse and addiction including alcohol intake. In this work, we have analysed the role of the N-terminal GAL fragment (1-15) [GAL(1-15)] in voluntary ethanol consumption in rats using the two-bottle choice paradigm as well as compare the effects of GAL(1-15) with GAL. The two-bottle choice test was used to determine the voluntary ethanol consumption of rats (Castilla-Ortega et al., 2016). Three sets of experiments were conducted. In the first set of experiments, a dose-response curve of GAL(1-15) was performed. Groups of rats (n=7-9) received i.c.v. GAL(1-15) 1 nmol, 3 nmol or vehicle 2, 14 and 24 hours before the measures. In the second set of experiments, the effects in two-bottle choice test of GAL 3 nmol, and GAL(1-15) 3 nmol were compared. In the last set of experiments rats received i.c.v. GAL(1-15) 3nmol combined with GALR2 antagonist M871 3 nmol 2 hours before the measures. GAL(1-15) 3nmol significantly decreased the alcohol intake 2 (p<0.05), 14 (p<0.05) and 24 (p<0.05) hours after its administration. Moreover, 2 hours after i.c.v. GAL(1-15) 3nmol a significantly decreased by 90% in preference was observed (p<0.05). This effect was maintained 24hours. GAL(1-15) also significantly reduced the alcohol intake (p<0.05) and preference (p<0.05) compared with GAL. GALR2 antagonist M871 significantly blocked the decreased in the ethanol intake (p<0.05) and preference (p<0.05) induced by GAL(1-15) 2 hours after its administration. These results indicates that GAL(1-15) induces a strong reduction in preference and alcohol consumption in rat, showing a differential role than GAL. These results may give basis for the development of novel therapeutic strategies using GAL(1-15) for treatment of alcohol addiction.Universidad de Málaga.
