Influence of the Surface Viscosity on the Breakup of a Surfactant-Laden Drop

We examine both theoretically and experimentally the breakup of a pendant drop loaded with an insoluble surfactant. The experiments show that a significant amount of surfactant is trapped in the resulting satellite droplet. This result contradicts previous theoretical predictions, where the effects of surface tension variation were limited to solutocapillarity and Marangoni stresses.We solve numerically the hydrodynamic equations, including not only those effects but also those of surface shear and dilatational viscosities. We show that surface viscosities play a critical role to explain the accumulation of surfactant in the satellite droplet.Ministerio de Economía y Competitividad DPI2013-46485-C3-1-R, TRA2013- 45808-RJunta de Extremadura GR1004

Acute onset supraclavicular lymphadenopathy coinciding with intramuscular mRNA vaccination against COVID-19 may be related to vaccine injection technique, Spain, January and February 2021

Monitoring adverse reactions following immunisation is essential, particularly for new vaccines such as those against COVID-19. We describe 20 cases of acute onset of a single supraclavicular lymphadenopathy manifesting between 24 h and 9 days after ipsilateral intramuscular administration of an mRNA-based COVID-19 vaccine, referred to our WHO Collaborating Centre for Vaccine Safety. Our results indicate that the swelling of supraclavicular lymph nodes following immunisation may constitute a benign and self-limited condition, related to a higher than recommended injection siteS

¿Cómo se construye el sujeto feliz contemporáneo? investigación sobre la relación entre el coaching vivencial y el cristianismo protestante en Bogotá, Colombia

La búsqueda de la felicidad ha sido uno de los propósitos más significativos en la vida de los seres humanos a lo largo de la historia, no solo en su afán por experimentarla y vivirla plenamente, sino también por la necesidad de lograr definirla y explicarla desde distintas posturas teóricas y religiosas. Actualmente, el sujeto contemporáneo y su noción de felicidad se han visto enmarcados por diferentes tipos de gobierno, los cuales no solo van desde patrones de conducta o belleza, sino también desde prácticas religiosas y psicológicas, que prometen guiarlo por la ruta de la redención y felicidad. Por esta razón, nuestra investigación se propuso estudiar cómo se construye el sujeto feliz contemporáneo, a partir de una relación entre dos de las vías más optadas por el hombre hoy en día para sentirse mejor consigo mismo y su entorno, que son el coaching y el cristianismo protestante. Siendo estas prácticas procedentes de sociedades del Atlántico norte, aún permanecen sin explorar cómo funcionan estos escenarios en países del sur. Por lo cual, hemos querido investigar y conocer lo que se encuentra sucediendo en estos espacios dentro de contextos latinoamericanos, específicamente en la ciudad de Bogotá, Colombia. Por este motivo, basadas en experiencias y preguntas personales acerca de por qué personas allegadas frecuentan esos espacios y logran verse transformados, se decidió llevar cabo un estudio de corte etnográfico, mediante el cual se pudo tener acceso a ambos espacios y lograr una inmersión en el área del cristianismo y el coaching donde se pone en escena la psicología tal y como se presenta en el coaching, las técnicas y los discursos utilizados por las iglesias cristianas. Para esto, se privilegió la experiencia de inmersión como herramienta de investigación. Por lo cual, en efecto surge la propia subjetividad de las investigadoras, lo cual sirvió de base para analizar y explorar las estrategias, instrumentos y discursos que se llevan a cabo en cada escenario y así dar cuenta qué impacto tiene lo que se observó en los otros y en nosotras mismas.The pursuit of happiness has been one of the most significant in the life of human beings throughout history purposes, not only in their eagerness to experience it and live it fully, but also by the need to define it and explain it from different theoretical and religious positions. Currently, the contemporary subject and his notion of happiness have been framed by different types of government, which not only ranging from behavioral patterns or beauty, but also from religious and psychological practices that promise to guide you through the path of redemption and happiness. For this reason, our research was to examine how contemporary happy subject is constructed from a relationship between two of the busiest ways man use today to feel better about yourself and your environment, wich are coaching and Protestant Christianity. Therefore, based on personal experiences and questions about why people close frequenting these places and manage to be transformed, it was decided to carry out a study ethnographic, by which it could have access to both spaces and achieve immersion area where Christianity and coaching is staged psychology as presented in coaching techniques and discourses used by Christian churches. For this, the immersion experience as a research tool is favored. Therefore the subjectivity of the researchers arises, indeed, which served as a basis to analyze and explore the strategies, tools and speeches that are held in each scenario and thus realize what impact does that observed in the others and ourselves.Psicólogo (a)Pregrad

Promotion of Healthy Habits in University Students: Literature Review

[EN] The increase in responsibilities, together with the multiple challenges that students face in the university period, has a direct impact on their healthy lifestyles. This literature review describes the benefits of promoting healthy habits in college, highlighting the fundamental role of prevention and promotion. A systematic review was carried out following the PRISMA recommendations, searching for information in the WOS and Scopus databases. On the other hand, a search was carried out within the existing and available grey literature. The review focused on finding information about physical activity, nutrition, and stress (with an emphasis on resilience and academic burnout) in university students. This bibliographic review includes 32 articles and six web pages, containing information on the benefits of physical activity, healthy habits, and health prevention. The information collected in this study shows that university students are exposed to multiple changes during this period, increasing as the academic years progress. At that time, their habits worsen, with low adherence to the Mediterranean diet, low physical activity, and high levels of stress, specifically increasing cases of academic burnout. The establishment of healthy habits during the university period is necessary, observing an improvement in all the variables studied. Prevention has played a fundamental role.S

Synthetic nanocarriers for the delivery of polynucleotides to the eye

This is the accepted manuscript of the following article: Saraiva, S., Castro-López, V., Pañeda, C., & Alonso, M. (2017). Synthetic nanocarriers for the delivery of polynucleotides to the eye. European Journal Of Pharmaceutical Sciences, 103, 5-18. doi: 10.1016/j.ejps.2017.03.001This review is a comprehensive analysis of the progress made so far on the delivery of polynucleotide-based therapeutics to the eye, using synthetic nanocarriers. Attention has been addressed to the capacity of different nanocarriers for the specific delivery of polynucleotides to both, the anterior and posterior segments of the eye, with emphasis on their ability to (i) improve the transport of polynucleotides across the different eye barriers; (ii) promote their intracellular penetration into the target cells; (iii) protect them against degradation and, (iv) deliver them in a long-term fashion way. Overall, the conclusion is that despite the advantages that nanotechnology may offer to the area of ocular polynucleotide-based therapies (especially AS-ODN and siRNA delivery), the knowledge disclosed so far is still limited. This fact underlines the necessity of more fundamental and product-oriented research for making the way of the said nanotherapies towards clinical translationThis work was supported by the European Union's Horizon 2020 - Research and Innovation Framework Programme under the Marie Sklodowska-Curie Grant agreement No. 642028 (NABBA) and by the Spanish Ministry of Economy and Competitiveness (MINECO) under Grant agreement No. RTC-2014-2375-1 (SURFeye)S

Necrólisis epidérmica tóxica atípica inducida por furosemida

Toxic epidermal necrolysis is a rare and severe skin disease, usually induced by drugs, that is characterized by an epidermal detachment that affects more than 30% of the total body surface. It is very important to keep it in mind, for the risk of secondary complications and high mortality. Furosemide is a diuretic of the sulfonamide group, widely used in daily clinical practice, which rarely produces this type of adverse reaction. We present an atypical clinical case of toxic epidermal necrolysis induced by furosemide. It differs from previous cases in the form of presentation, diagnosis and evolution.La necrólisis epidérmica tóxica es una enfermedad cutánea severa y poco frecuente, generalmente inducida por fármacos, que se caracteriza por un desprendimiento epidérmico que afecta a más del 30% de la superficie corporal total. Es importante tenerla en cuenta por el riesgo de complicaciones secundarias y su elevada mortalidad. Furosemida es un diurético del grupo de las sulfonamidas ampliamente utilizado en la práctica clínica diaria que raramente produce este tipo de reacción adversa. Presentamos un caso clínico atípico de necrólisis epidérmica tóxica por furosemida, que difiere con lo anteriormente publicado en forma de presentación, diagnóstico y evolución

Spontaneous tonsillar hemorrhage as initial presentation of acute promyelocytic myeloid leukemia

Actualmente, la hemorragia espontánea amigdalar es un signo faríngeo muy infrecuente. Su etiología habitual se relaciona con la amigdalitis crónica y su tratamiento suele ser local y sintomático. El caso clínico que presentamos refuerza la importancia del estudio integral del paciente con hemorragia espontánea amigdalar, ya que, puede ser la presentación inicial de enfermedades hematológicas graves.Currently, spontaneous tonsillar hemorrhage is a very uncommon pharyngeal sign. Its etiology is usually related to chronic tonsillitis and its treatment uses to be local and symptomatic. The case that we report reinforces the importance of the global study of the patient with spontaneous tonsillar hemorrhage because it can be the initial presentation of serious hematologic diseases

The smartphone in research: The instant messenger as an ally to reduce trial drop-outs

El permanente avance de la telefonía móvil en la vida diaria puede traducirse en beneficios para los investigadores, especialmente en el campo de la salud. Hay varios motivos para ello: la reducción de gastos derivados de las llamadas telefónicas, del SMS, así como del tiempo dedicado a la puesta en contacto con los sujetos; puede ser una herramienta de anonimato perfecta, asociando un código a un número de teléfono; se tiene constancia del momento en que el sujeto ha leído la información suministrada por el investigador y además permite una mayor cercanía entre el participante y el investigador
