Detección de Aflatoxina M1 en leche caprina de Mendoza, Argentina

Las micotoxinas más comúnmente analizadas en los alimentos son las aflatoxinas, ocratoxinas, fumosinas y zearaleonona. Sin embargo, solo las aflatoxinas son sometidas a límites legales en cuanto a su valor en la alimentación. La aflatoxina B1, es un tipo de toxina que puede encontrarse en alimentos para consumo de ganado lechero, que al entrar al organismo del animal, por procesos metabólicos, se transforma en aflatoxina M1 (AFM1), la cual es secretada por la leche. Esta toxina es responsable de múltiples patologías en animales y seres humanos debido a su carácter tóxico, mutagénico y teratogénico. Mendoza es considerada una de las provincias con mayor producción de leche caprina del país (16,6%), y siendo esta leche considerada un producto importante, no solo para la producción de derivados lácteos sino también para alimentación de individuos alérgicos a la proteínas de la leche de vaca, que en mayor medida son niños lactantes y que a su vez son los más susceptibles a la intoxicación con aflatoxinas

Bronchoscopist's perception of the quality of the single-use bronchoscope (Ambu aScope4™) in selected bronchoscopies: a multicenter study in 21 Spanish pulmonology services

Background: The disposable bronchoscope is an excellent alternative to face the problem of SARS-CoV-2 and other cross infections, but the bronchoscopist's perception of its quality has not been evaluated. Methods: To evaluate the quality of the Ambu-aScope4 disposable bronchoscope, we carried out a cross-sectional study in 21 Spanish pulmonology services. We use a standardized questionnaire completed by the bronchoscopists at the end of each bronchoscopy. The variables were described with absolute and relative frequencies, measures of central tendency and dispersion depending on their nature. The existence of learning curves was evaluated by CUSUM analysis. Results: The most frequent indications in 300 included bronchoscopies was bronchial aspiration in 69.3% and the median duration of these was 9.1 min. The route of entry was nasal in 47.2% and oral in 34.1%. The average score for ease of use, image, and aspiration quality was 80/100. All the planned techniques were performed in 94.9% and the bronchoscopist was satisfied in 96.6% of the bronchoscopies. They highlighted the portability and immediacy of the aScope4TM to start the procedure in 99.3%, the possibility of taking and storing images in 99.3%. The CUSUM analysis showed average scores > 70/100 from the first procedure and from the 9th procedure more than 80% of the scores exceeded the 80/100 score. Conclusions: The aScope4™ scored well for ease of use, imaging, and aspiration. We found a learning curve with excellent scores from the 9th procedure. Bronchoscopists highlighted its portability, immediacy of use and the possibility of taking and storing images

Ubiq-Ideas Machin: Ubiquitous computing system to support creative ideas generation sessions in open innovation [Ubiq-Ideas Machine: Sistema de cómputo ubicuo para apoyar sesiones creativas de generación de ideas en procesos de innovación abierta]

Ideas emerge in the less imagined scenarios, and it is mandatory to have a set of tools which ease their incorporation without time/place/access medium constraints, in order to maximize opportunities and avoid losing worthy contributions that become in incomes for innovations processes in companies or any other institution interested in actively involving their customers, employees, providers and other stakeholders in the Value Chain by means of co-creation. In this work we propose Ubiq-Ideas Machine, a ubiquitous computing prototype to support creative sessions of ideas generation by using a distributed scheme. This tool was built by reviewing literature and a strong field work with ubiquitous computing experts. We present the process until proposing the design and prototype generation. After a first assessment, an interesting projection is revealed due to a high commercialization impact

Oxidation behavior of dense Yttrium doped B2-NiAl bulk material fabricated by ball milling self-propagating high-temperature synthesis and densified by spark plasma sintering

The effect of Y additions on the oxidation behavior in furnace cyclic tests and its correlation with thermogravimetric analysis of sintered NiAl alloys is here reported. Part of the samples got an EB-PVD 7YSZ coating on top. Highly ordered B2-NiAl intermetallic powder was obtained by self-propagating high-temperature synthesis (SHS) during ball milling of elemental precursors with Y additions in amounts between 0 and 1.5 at.%. The SHS process was optimized to identify the combination of milling parameters that leads to a sharp increase in the reaction temperature for intermetallic synthesis. The tested samples consisted of NiAlY buttons densified by spark plasma sintering (SPS). Furnace cyclic testing of the SPSbuttons at 1100 °C showed high resistance to spallation of the 7YSZ top-coat and a significant decrease in its oxide growth kinetics attributed to Y-additions. Contents below 0.5 at.% Y reduce the oxidation kinetics of NiAl exposed to thermal cycles at 1100 oC, while higher Y contents are favorable for a longer TBC lif
