Socialización política juvenil y movilidad estudiantil pendular en localidades pequeñas: hacia la construcción de una pregunta etnográfica

Si bien el campo de los estudios en juventudes y política se ha ampliado notablemente en la última década, la mayor parte de ellos dirigen su atención a las zonas urbanas y, en menor medida, al ámbito de la ruralidad. A fin de seguir ampliando el conocimiento sobre la socialización política de los jóvenes, el presente artículo tiene como finalidad realizar un primer acercamiento a la pregunta por la relación entre la movilidad estudiantil pendular a la Ciudad de La Plata y el proceso de socialización política de los jóvenes estudiantes provenientes de ciudades pequeñas. Puntualmente me interesa indagar el modo en que los jóvenes llegan a convertirse en actores sociales y políticamente activos en sus localidades de pertenencia. Desde la perspectiva de la antropología de la política (Peirano 1996; Kurshnir, 2007) y desde los estudios sobre formación de subjetividades políticas juveniles (Kriger, 2010; 2013, 2017) esta pregunta se desprende de uno de los objetivos que estructura mi proyecto de investigación de maestría: Jóvenes y política. Un estudio sobre socialización política juvenil y su relación con la movilidad estudiantil pendular en localidades pequeñas del Partido de Punta Indio (Pcia. de Buenos Aires). El cual tiene por objetivo contribuir al campo de estudios sobre juventudes y política desde una perspectiva antropológica abordando la socialización política juvenil en localidades pequeñas.GT37 - La política como proceso vivo: creatividad social e imaginación antropológica en el análisis de la política colectiva y la (re)producción de la vida.Universidad Nacional de La Plat

Locoregional versus general anesthesia in carotid surgery: Is there an impact on peri-operative myocardial ischemia? Results of a prospective monocentric randomized trial.

PURPOSE: The incidence of cardiac morbidity and mortality in patients who undergo carotid surgery ranges from 0.7% to 7.1%, but it still represents almost 50% of all perioperative complications. Because no data are available in literature about the impact of the anesthetic technique on such complications, a prospective randomized monocentric study was undertaken to evaluate the role of local anesthesia (LA) and general anesthesia (GA) on cardiac outcome. METHODS: From November 1995 to February 1998, 107 patients were classified by the cardiologist as cardiac patients (IHD; history of myocardial infarction, previous myocardial revascularization procedures, or myocardial ischemia documented by means of positive electrocardiogram [ECG] stress test results) or noncardiac patients (NIHD; no history of chest pain or negative results for an ECG stress test). The patients were operated on after the randomization for the type of anesthesia (general or local). Continuous computerized 12-lead ECG was performed during the operative procedure and 24 hours postoperatively. The end points of the study were ECG modifications (upsloping or downsloping more than 2 mm) of the sinus tachycardia (ST) segment. RESULTS: Fifty-five patients were classified as IHD, and 52 were classified as NIHD. Twenty-seven of the 55 IHD patients (49%) and 24 of 52 NIHD patients (46%) were operated on under GA. Thirty-six episodes of myocardial ischemia occurred in 22 patients (20.5%). Episodes were slightly more frequent (58%) and longer in the postoperative period (intraoperative, 10 +/- 5 min; postoperative, 60 +/- 45 min; P <. 001). As expected, the prevalence of myocardial ischemia was higher in the group of cardiac patients than in noncardiac group (15 of 55 patients [27%] vs 7 of 52 patients [13%]; P <.02). By comparing the two anesthetic techniques in the overall population, we found a similar prevalence of patients who had myocardial ischemia (GA, 12 of 52 [23%]; LA, 10 of 55 [18%]; P = not significant) and a similar number of ischemic episodes per patient (GA, 1.5 +/- 0.4; LA, 1.8 +/- 0.6; P = not significant). Episodes of myocardial ischemia were similarly distributed in intraoperative and postoperative periods in both groups. It is relevant that under GA, IHD patients represent most of the population who suffered myocardial ischemia (83%). On the contrary, in the group of patients operated on under LA, the prevalence was equally distributed in the two subpopulations. CONCLUSION: The results confirm the different hemodynamic impact of the two anesthetic techniques. Patients who received LA had a rate of myocardial ischemia that was half that of patients who had GA. The small number of cardiac complications do not permit us to make any definitive conclusion on the impact of the two anesthetic techniques on early cardiac morbidity, but the relationship between perioperative ischemic burden and major cardiac events suggests that LA can be used safely, even in high-risk patients undergoing carotid endarterectomy

Using Glycerol to Produce European Sea Bass Feed With Oleaginous Microbial Biomass: Effects on Growth Performance, Filet Fatty Acid Profile, and FADS2 Gene Expression

Using a circular economy concept, the present study investigated the use of crude glycerol, a primary by-product of biodiesel production, as a low-priced nutrient source for heterotrophic cultivation of the fungus-like protist Schizochytrium limacinum SR21 strain. The whole biomass of this oleaginous microorganism, rich in docosahexaenoic acid (DHA) and high-quality proteins, was then paired with a vegetable oil (VO) source and used to replace fish oil (FO) in European sea bass (Dicentrarchus labrax) feeds. Four nutritionally balanced diets were formulated: diet FO (a FO-based diet), diet VO + 0 (a VO-based diet without S. limacinum), and diets VO + 5 and VO + 10 that were VO-based feeds supplemented with 5 and 10% of S. limacinum, respectively. After a 3-month feeding trial, fish of all dietary groups tripled their initial weight, but growth and feeding efficiencies of D. labrax were not significantly different among treatments. Although the formulated diets were balanced for polyunsaturated fatty acids (PUFAs), fish fed with feeds containing either VO or VO plus 5 and 10% of S. limacinum biomass had significantly higher levels of PUFAs in the flesh than fish fed the FO-based diet. Values of health-related lipid indexes, such as atherogenicity index, thrombogenicity index, and flesh lipid quality as well as n-6/n-3 and PUFAs/SFAs ratios confirmed the high nutritional value of sea bass filet, thus representing a healthy product for human consumption. Although the PUFAs/SFAs ratio showed a significantly higher value in fish fed with VO-based diets supplemented with S. limacinum than in those fed with FO diet, suggesting a better filet quality, the n-6/n-3 ratio clearly indicated that filet quality of dietary group FO was best (value of 0.55) and that of group VO + 10 second best (value of 0.98). We also evaluated the nutritional regulation of 16-desaturase (or fads2) gene expression in European sea bass liver. European sea bass fed the VO + 0 diet had the highest number of mRNA copies for 16-desaturase (or fads2), fish fed with diet VO + 10 the lowest. Our study adds to the growing body of literature concerning the use of thraustochytrid biomass as a valid alternative to marine-derived raw materials for European sea bass feeds

Imported severe malaria and risk factors for intensive care: A single-centre retrospective analysis.

OBJECTIVES: This study aims to identify the risk factors for intensive care (IC) in severe malaria patients admitted to the "Lazzaro Spallanzani" National Institute for Infectious Diseases, Rome, Italy. METHODS: All patients with confirmed severe malaria and hospitalized between 2007 and 2015 were included in the analysis and stratified into two groups: those requiring IC and those who did not. Five prognostic malaria scores were estimated; clinical severity at IC unit admission was assessed using the Sequential Organ Failure Assessment and the quick-Sequential Organ Failure Assessment scores. Univariate and multivariate analysis were performed to assess factors independently associated to IC. RESULTS: A total of 98 severe malaria patients were included; 10 of them required IC. There were no deaths or sequelae. Patients requiring IC had higher severity scores. At the multivariate analysis, only the number of World Health Organization criteria and the aspartate aminotransferase value were independently associated with the need of IC. CONCLUSIONS: An early and accurate assessment of the severity score is essential for the management of severe malaria patients

Foam fractionation efficiency in particulate matter and heterotrophic bacteria removal from a recirculating sea bass (Dicentrarchus labrax) system.

In recirculating aquaculture systems (RAS), particulate matter and bacterial communities management are required to maintain water quality. Foam fractionation is a water treatment technology that can be easily applied to water reuse systems to remove bacteria and suspended solids. This study investigated the efficiency of foam fractionation in removing particulate matter and heterotrophic bacteria in a closed recirculating seabass (Dicentrarchus. labrax) system. This system consisted of 10 rearing tanks, a skimmer acting as the foam separation system (SKIM1), a biofilter unit, and an UV unit. The efficiency of SKIM was analyzed for different foam fractionation operation times (50on/50off, 150on/150off and 300on/300off) and for different sizes of particulate matter (>60 mm, 60\u20138 mm, 8\u2013 1.2 mm, and 1.2\u20130.22 mm). The removal of particulate matterwas influenced by different particle sizes with higher removal percentages for the >60 mm and 1.2\u20130.22 mm categories of 96.8 and 100%, respectively. Nevertheless, these categories represented the lower percentage of total solid compositions in the RAS water studied (>60 mm = 7.14 2.78%, and 1.2\u20130.22 mm = 18.27 2.50%). The removal of heterotrophic bacteria did not correlate with the operation time or particle size and SKIM removal percentages ranged between 32 and 88%

Effect of dietary Astaxanthin sources supplementation on muscle pigmentation and lipid peroxidation in rainbow trout (Oncorhynchus mykiss)

Astaxanthin is one of the major carotenoids in aquatic animals including salmonid fishes and is the preferred pigments added to salmon feed. It&rsquo;s also a powerful antioxidant compared to other carotenoids and that may confer numerous health benefits. The aim of the present experi- ment was to investigate the effect of Astaxanthin deposition on the lipids peroxidation by studying the Malondialdeide (MDA) level in muscle of rainbow trout (Oncorhynchus mykiss). The Astaxanthin concentrations in fish fed with a commercial sources as Lucantin&reg;Pink (BASF Ludwigshafen, Ger- many) reached values to 5.76&plusmn;0.18x10-3 mg/g after 50 days feeding, while the MDA concentration de- creased from 1.56x103 to 0.45x103 ng/g. The correlation between MDA and Astaxanthin concentrations decreased linearly and confirmed the antioxidant properties of the pigment by reducing the lipids peroxidation

Molecular characterization and in vivo expression of hypoxia inducible factor (HIF)-1α in sea bass (Dicentrarchus labrax) exposed to acute and chronic hypoxi

Aquatic hypoxia is a frequent event and in fish a complex set of physiological and bi- ochemical alterations are employed to cope with this environmental stress. Many of these adjustments depend to a large extent on changes in the expression of genes that encode for physiologically relevant proteins. Genes that are induced by hypoxia appear to share a common mode of transcriptional regula- tion. This induction depends upon activation of a transcription factor, the hypoxia inducible factor-1 (HIF-1), which is a heterodimer composed of two subunits: &alpha; ‧ and &beta;. In this study we report first on the molecular cloning and characterization of HIF-1&alpha; ‧ in sea bass (Dicentrarchus labrax). The full-length sea bass cDNA for HIF-1&alpha; was isolated and deposited in the GenBank with accession no. DQ171936. It consists of 3317 base pairs (bp) carrying a single open-read- ing frame that encompasses 2265 bp of the coding region and 1052 bp of the 3&rsquo; UTR. We then utilized the real-time PCR technology to monitor dynamic changes in levels of HIF-1&alpha; ‧ tran- scripts, in response to acute and chronic hypoxic stress. The number of HIF-1&alpha; ‧ mRNA copies were signifi- cantly increased in response to both acute (1.9 mg/L, dissolved oxygen for 4 hours) and chronic (4.3 mg/L, DO for 15 days) hypoxia in sea bass, whereas it remained unchanged in fish exposed to hyperoxic (DO 13.5&plusmn;1.2 mg/L, 155 % saturation) conditions. This is the first study carried out to investigate the behaviour of HIF-1&alpha; gene transcripts during hypoxia in representative of marine hypoxia-sensitive fish species
