Phenotypic variability, both based on phenotypic plasticity and genetic diversity, can be a main factor affecting the invasion process of alien species. Limnoperna fortunei (Dunker 1857) was introduced in South America around 1990, in the Rio de la Plata estuary, Argentina, from where it spread swiftly to cover most of the basin and other smaller watersheds. However, some environments have not been colonized and, presumably, the survival of this species was affected by different environmental factors such as suspended solids, salinity, and pollution. L. fortunei showed high genetic and morphological variability, showing a distribution strongly affected by human activities and its dispersal vectors. The degree of phenotypic variability would be playing a main role in its establishment, or not, in the different environments. Morphological and metabolic variations, including changes in the growth rate, development of internal organs or changes in the rate of filtration and respiration in border areas of its distribution or under extreme environmental conditions, would allow to explain, together with other variables such as the presence of dispersal vectors, the current distribution pattern.

Citizen science involves the participation of the entire community in scientific activities and promotes the active contribution of citizens in research projects through their efforts, knowledge, tools and resources. The community living nearby a reservoir suffers the main consequences of cyanobacteria blooms and usually has a popular knowledge of the problem and a great enthusiasm to collaborate in research tasks. This study describes a joint project between the community and the Faculty of Exact, Physical and Natural Sciences of the National University of Cordoba, the Special Rescue Group of Calamuchita and the Provincial Administration of Water Resources. This initiative includes the collaborative monitoring of cyanobacterial blooms in Los Molinos reservoir in an unprecedented experience in reservoirs in the province of Cordoba (Argentina). Secchi depth is described as an excellent indicator for recreational use. The participation of students of the Alfonsina Storni school in Potrero de Garay and of the Special Rescue Group of Calamuchita, who reported valuable data on the reservoir conditions in relation to cyanobacterial blooms and transmit the main results and conclusions to their families, coworkers and the whole community, is here underscored.

Nuts contain a high content of oleic acid and/or polyunsaturated acids, so their intake reduces the level of total cholesterol and LDL cholesterol in the blood, which is associated with a lower incidence of cardiovascular diseases. Besides, nuts have beneficial effects on human health due to the presence of antioxidants (polyphenols and tocopherols). In this study, lipid content, fatty acid profile and polyphenols and tocopherols content of some nuts were determined: walnuts, pecans, hazelnuts, almonds, peanuts, pistachios and cashews. The extraction of polyphenols in hazelnuts was optimized by using different mixtures of solvents as well as several conditions of temperature and extraction times. The mixture water/acetone (80:20) at 25 °C during 24 hours showed the highest content of polyphenols. The polyphenol content of the extracts obtained from the nuts showed values in the range between 427 ppm (almonds) and 8805 ppm (walnuts), while the content of tocopherols, ranges between 160 ppm (cashews) and 358 ppm (walnuts). Thus, the analyzed nuts have important antioxidant contents but in different amounts. Furthermore, the nutshell offers a barrier to slow down the oxidation processes of the oil present in the product.

This work evaluated the use of apple juice by-product as a functional ingredient in healthy baking premixes. Due to its high fiber content, this raw material was decided to be used as an enrichment strategy for food product formulation. Apple pomace was obtained as a by-product of the juice industry and was dried and ground to obtain apple flour. Premixes for fiber enriched muffins, cakes and biscuits were developed by partially substituting wheat flour for apple flour to obtain a product that could be labeled as “source of fiber”. The products developed were satisfactorily evaluated, but even if fiber had a negative effect on the sensory characteristics of the products, it also caused them to be perceived as healthy. Considering that the cake was the product with the highest acceptability, it was selected to make a comparative study with competing market-leading products. This comparison revealed that the developed premix contributes to the preparation of another product concept, since it was described differently than commercial products, but with comparable acceptability. Finally, it can be said that the development of premixes using apple juice by-product constitutes a new category of functional foods, which satisfies both the needs of consumers and those of the industry, making it possible to transform an environmental problem into a potential economic return for companies.

With the increasing advance of nanotechnology, both in the academic and commercial areas, the need for nanoparticle characterization techniques and protocols has grown. Although there are several measurement methods, the "true" size of nanoparticles cannot be understood in absolute terms but related to the material, the technique and to the protocols or criteria associated with these measurements. In other words, when we talk about the size of a particle, we must take into account two basic questions: what are we measuring? and how do we measure? From the metrological point of view, it is important to discuss the criteria to take into account, and which additional parameters should we report when presenting a nanoparticle size result. The present work shows, comparatively, the characterization of the size of homogeneous gold nanoparticles, using different techniques and measurement criteria with DLS, UV-VIS and HR-TEM methods. The results show how the definition of size is important to establish a result, as well as the criteria chosen when performing the particle counting.

The process of calibration of ISO 3650 gauge blocks by mechanical comparison includes not only a significative demands on the stabilization of environmental conditions, but also a significant test time for the technician who operates the comparator and performs the calibration of each block. A recent development at Laboratorio Tecnologico del Uruguay (LATU), in its role of National Metrology Institute of Uruguay, allows the entire process to be autonomously carried out by means of a robotic system built with simple hardware components, and controlled by custom-made software to manage workflow and gauge block comparator actions. The software performs hardware control during the process, and automatic data acquisition of the environmental conditions as well as comparator readings. Finally, this software performs automatic data processing and calibration results with their associated uncertainty without any technician involvement. This work describes in detail the characteristics of the automated calibration system, the elements used for mechanical automation, its assembly and the software strategy used for system administration.

Introduccion: Las enfermedades pulmonares intersticiales son un grupo muy heterogeneo de afecciones que tienen manifestaciones clinicas, radiologicas y funcionales en comun. Su epidemiologia esta documentada en forma parcial y su etiologia es muy variada. El diagnostico se basa en la clinica, la tomografia computada de alta resolucion y, en algunos casos, la histologia. Objetivos: describir la poblacion de pacientes con diagnostico de enfermedad pulmonar intersticial asistidos en la Policlinica de Intersticiopatias del Hospital Pasteur en el periodo comprendido entre el 5 de mayo de 2017 y el 17 de mayo de 2019. Materiales y metodos: Estudio descriptivo, observacional y transversal. Se utilizo un muestreo por conveniencia. Las variables analizados fueron: edad, sexo, comorbilidades, etiologia, patron tomografico predominante, funcional respiratorio (Test de Marcha 6 Minutos y espirometria forzada con difusion de monoxido) y tratamiento instituido. Se obtuvo consentimiento informado y el trabajo fue aprobado por el Comite de Bioetica del Hospital Pasteur. Resultados: 20 de los 42 pacientes asistidos eran portadores de enfermedad pulmonar intersticial. Predomino el sexo femenino (14 pacientes, 70%). La edad media fue 60 ± 16.84 anos. La comorbilidad mas frecuente fue el tabaquismo (13 pacientes, 65%). En 6 pacientes (30%) se identificaron exposiciones ambientales o laborales de riesgo. La etiologia fue determinada en 15 pacientes (75%), siendo en 10 pacientes (50%) asociada a enfermedades autoinmunes sistemicas y en 3 pacientes (15%) neumonitis por hipersensibilidad. La mayoria (11 pacientes, 55%) tuvieron patrones tomograficos inespecificos. 94.11% tuvieron un patron restrictivo en el estudio funcional respiratorio, predominando la restriccion moderada a severa. La difusion monoxido media fue 47.25 ± 16.71%. 11 pacientes (55%) fueron tratados con corticoides sistemicos y 2 pacientes necesitaron oxigeno a permanencia. Conclusiones: Las caracteristicas demograficas, etiologia, patrones tomograficos y tratamiento instituidos estan influenciados por un sesgo de seleccion, ya que una elevada proporcion de pacientes son derivados desde policlinicas de enfermedades autoinmunes sistemicas. Es fundamental un manejo integral de estos pacientes porque la asociacion con otras enfermedades que pueden contribuir en la sintomatologia es frecuente. Las enfermedades pulmonares intersticiales encontradas son mayormente severas y de diagnostico tardio.

Introduction. Venous Thromboembolic Disease (VTE) is a serious, frequent and preventable medical complication in hospitalized patients. Although the efficacy of its prevention (pharmacological and / or mechanical) has been demonstrated, its adherence is insufficient at the international and national level. Goals. 1-Contribute to the knowledge of the national reality on thromboprophylaxis in hospitalized patients in order to optimize their adherence. 2-To know the prevalence of the risk of VTE in the analyzed population and evaluate adherence to the indication of thromboprophylaxis. Methodology. Observational, descriptive, crosssectional and multicenter study of all medical-surgical patients admitted to moderate care wards of Hospital de Clínicas, Hospital Maciel and Sanatorio Americano, during April 26 and 27, 2017. Sociodemographic variables and the percentage of patients were studied at risk of VTE. In patients at risk, the percentage who received pharmacological thromboprophylaxis was assessed. Results. 427 patients were included. 63% (269) presented medical pathology and 37% (158) surgical pathology. 294 (68.9%) were at risk of VTE, of which 55.8% (164) were receiving pharmacological prophylaxis. They did not receive it by omission 19.4% (57), due to contraindication 18.4% (54) and because they were anticoagulated 6.4% (19). None of the patients with a contraindication for pharmacological thromboprophylaxis received mechanical measures. The population of patients at risk who received thromboprophylaxis was statistically higher in medical patients (66.7%, 110/165) than in surgical patients (41.9%, 54/129) p <0.001. Of the 130 patients who did not have an indication for drug thromboprophylaxis, 9.3% (12) received it. All these patients presented medical pathology. Conclusions. In our study we found 68.9% of patients at risk, which confirms that it is a serious and frequent problem. With regard to thromboprophylaxis, although we observed a clear improvement compared to previous national studies, we believe that it is still insufficient and we must continue working on this line.
