Yogur desnatado con transglutaminasa microbiana: evaluación de la aceptación del consumidor

The decrease in the fat content of yoghurt causes sensory modifications. Microbial transglutaminase (TG) has been proposed as an alternative for reducing the problems caused by the fat reduction. This work deals with the evaluation of the sensory profile, acceptance and preferences of skim yoghurt produced with TG at pilot scale. A group of 124 consumers of yoghurts were randomly selected. A lower firmness has been observed in yoghurt without TG (NoTG). TG Yoghurt has shown a lower whey odor and less acid taste than NoTG yoghurt. Free whey was not observed in the TG yoghurt. Despite of those differences, consumers only observed minor textural differences. In terms of overall acceptance and preference, no statistically significant differences were observed. The use of TG avoids the addition of milk protein or other texture additives into the yoghurt, decreasing production cost with the same overall acceptance and preference by consumers.La disminución del contenido graso del yogur provoca modificaciones sensoriales. La transglutami- nasa microbiana (TG) se ha propuesto como una alternativa para reducir los problemas causados por la reducción de grasa. Este trabajo trata sobre la evaluación del perfil sensorial, la aceptación y la preferencia del yogur desnatado producido con TG en una planta piloto. Un grupo de 124 consumidores de yogures fueron seleccionados al azar. Una menor firmeza se observó en el yogur sin TG (NoTG). EL yogur con TG mostró menor olor a suero, menor sabor ácido que el yogur NoTG. No se observó suero en el yogur con TG. A pesar de esas diferencias, los consumidores solo observaron pequeñas diferencias de textura. En términos de aceptación global y preferencia, no se observaron diferencias estadísticamente significativas. El uso de TG evita la adición de proteínas de la leche u otros aditivos para mejorar la textura del yogur, lo que reduce los costes de producción manteniéndose la aceptación y preferencia por parte de los consumidores.This research was supported by MICINN (Spain) [Project No. RTC2014- 1835-2] and Consellería de Cultura, Educación e Ordenación Universitaria, Xunta de Galicia (ES) [Project No. ED431B 2016/009]S

Integra BioFis 5.0. A collaborative, participatory and interdisciplinary experience for undergraduates in nursing

The pandemic has forced us to reinvent ourselves and to consider new strategies in education. Motivation, fundamental to student performance, has been seriously compromised. In this sense, the type of motivation we are interested in "fostering" is intrinsic motivation, closely linked to the concept of learning-centered goals and objectives. The action implemented is committed to the approach to challenge-based learning-gamification in the Degree in Nursing (UAH), in order to develop an integrative training with an interdisciplinary focus. Biochemistry and Physiology came together in Integra BioFis 5.0 and through participatory and collaborative techniques we pursued meaningful learning. All the students of the Biochemistry and Physiology subjects (n = 120) took part in the learning experience, organized in 12 teams. The action was carried out online through the virtual platform: - An initial session, in which the objectives, methodology, timetable and evaluation criteria were clarified. Topics that aroused the students? interest were randomly assigned (https://bit.ly/3tfJaCi). The assigned tutors guided the students in overcoming the challenges of each stage. - The development of the action consisted of a series of phases: i) documentation and literature search; ii) integration of objectives and choice of presentation format; iii) elaboration of the graphical document; iv) peer review of presentations and voting for the best contribution. The students' papers, as well as the rubrics with comments and suggestions from each of the instructors, were returned to the teams immediately. - A final session, in which they reflected on the activity they had carried out, highlighting the positive aspects of the training for the development of competences and skills: i) search for information from quality sources; ii) synthesis of contents; iii) work as a team; iv) elaboration of an original and own work. Voting was then shown for the papers presented, revealing the names of the three teams with the most votes, finalists and winners. Learning assessment was conducted by taking into account the influence of learning on motivation and the student's self-esteem and competences, with indicators such as progress, content, sources, graphical document production, teamwork and responsibility, among others. As an important element that makes gamification work, a reward for participation (awarding of a participation diploma) and for the best Integra BioFis 5.0 graphic document presented (awarding of diplomas and prizes-gifts to the members of the winning team) was considered as an important element that makes gamification work. From this educational strategy, it can be concluded that gamification is a constructive experience, taking advantage of all the benefits of implementing the overcoming of challenges in the educational environment. This has had an impact on teaching practice, to the extent that what has been "reflected" and "worked" in Integra BioFis 5.0 has contributed to improving the quality of virtual teaching, "fostering" intrinsic motivation in students.Universidad de Alcal

Analysis of Minor Proteins Present in Breast Milk by Using WGA Lectin

Breast milk is a complex and dynamic biological fluid and considered an essential source of nutrition in early life. In its composition, the proteins have a relevant biological activity and are related to the multiple benefits demonstrated when compared with artificial milks derived from cow’s milk. Understanding human milk composition provides an important tool for health care providers toward the management of infant feeding and the establishment of breastfeeding. In this work, a new technique was developed to increase the knowledge of human milk, because many of the components remain unknown. To isolate minor proteins present in breast milk by using WGA lectin, breast milk was centrifuged to remove cells and separate the fat phase from the serum phase. The serum obtained was separated into two groups: control (n = 3; whole serum sample from mature milk) and WGA lectin (n = 3; sample processed with WGA lectin to isolate glycosylated proteins). The samples were analyzed by high-performance liquid chromatography coupled to mass spectrometry (HPLC/MS). A total of 84 different proteins were identified from all of the samples. In the WGA lectin group, 55 different proteins were isolated, 77% of which had biological functions related to the immune response. Of these proteins, there were eight WGA lectin group exclusives, and two had not previously been described in breast milk (polyubiquitin-B and POTE ankyrin domain family member F). Isolation by WGA lectin is a useful technique to detect minor proteins in breast milk and to identify proteins that could not be observed in whole serum

Designing a biochemical escape room for undergraduate students

Gamification is increasingly used in Higher Education to foster intrinsic motivation of undergraduate students. In this sense, we designed the Biochemical Escape Room. The students, organized in teams and through the overcoming of challenges, tackled the contents reviewed in the face-to-face classes. In addition, the tests helped in the training of different soft skills such as creative thinking, deductive thinking, collaborative work, teamwork, manual dexterity, communication and time management. The activity was designed in several phases: i) setting the learning objectives; ii) adapting the physical spaces to the teams involved in the "game"; iii) acquiring the material; iv) preparing, placing the tests and the clues and general rehearsal before D-day; and v) D-day. The results obtained after the design of the Biochemical Escape Room and its implementation show that one of the objectives of the activity had been achieved: it provided an "injection" of motivation for teachers and students. And although there are certain aspects that need to be improved, designing the escape room for the biochemistry laboratories has meant a significant change both for the instructors, in the way we teach, and for the students, in the manner they learn.Universidad de Alcalá.

Experiências do pessoal de enfermagem do Hospital Sao Joao de Deus em Tenerife no tempo de Covid-19

La enfermedad infecciosa por coronavirus 2019 (COVID19) es una infección del tracto respiratorio causada por un coronavirus de reciente aparición (2019 –nCoV), que fue reconocido por primera vez en Wuhan, China, en diciembre de 2019. La secuencia genética del virus sugiere que se trata de un betacoronavirus, estrechamente vinculado al virus de la SARS. El principal objetivo de este estudio es conocer las vivencias del personal de enfermería, en las unidades de hospitalización de Medicina Interna, en tiempos de COVID-19, en el Hospital San Juan de Dios de Tenerife, con el fin de averiguar medidas estratégicas de intervención que ayuden a afrontar estas situaciones en caso de rebrote por coronavirus SARS-CoV-2. Se trata de una investigación cualitativa de tipo fenomenológico. Se ha decidido por este tipo de estudio debido a la mayor proximidad con la realidad vivenciada por el personal de enfermería, al estar en la primera línea de atención a pacientes contagiados/as por el virus. Tras los resultados obtenidos, el personal de enfermería coincide en que cuando una situación de estas características, como es una pandemia, nos sobreviene, al principio existe desconcierto y desorden. Los días van pasando y los protocolos y los circuitos quedan establecidos y la sensación de seguridad durante los turnos se instaura. Como conclusión, consideramos imprescindible mantener una formación continuada y el cuidado a nivel psicológico del personal de enfermería en situaciones de pandemia; ya que en todo este proceso, los sentimientos y las emociones se intensifican y se producen muchas circunstancias adversas que pueden dificultar la práctica asistencial diaria.Infectious disease coronavirus 2019 (COVID19) is a respiratory tract infection caused by a recent-onset coronavirus (2019 –nCoV) that was first recognized in Wuhan, China, in December 2019. The genetic sequence of the virus suggests that it is a betacoronavirus, closely related to the SARS virus. The main objective of this study is to know the experiences of the nursing staff, in the Internal Medicine hospitalization units, in times of COVID-19, at the San Juan de Dios Hospital in Tenerife in order to find out strategic intervention measures that help cope with these situations in the event of a SARS-CoV-2 coronavirus outbreak. It is a qualitative research of a phenomenological type. It has been decided on this type of study due to the greater proximity to the reality experienced by the nursing staff as they are in the first line of care for patients infected by the virus. After the results obtained, the nursing staff agrees that when a situation of these characteristics, such as a pandemic, occurs to us at the beginning, there is confusion and disorder. The days go by and the protocols and circuits are established and the feeling of security during shifts is established. In conclusion, we consider it essential to maintain continuous training and psychological care for nursing personnel in pandemic situations; Since throughout this process, feelings and emotions intensify and many adverse circumstances occur that can make daily care practice difficult.Doença infecciosa coronavírus 2019 (COVID19) é uma infecção do trato respiratório causada por um coronavírus de início recente (2019 -nCoV) que foi reconhecido pela primeira vez em Wuhan, China, em dezembro de 2019.

Chondroid Tumors: Review of Salient Imaging Features and Update on the WHO Classification

Chondrogenic tumors are typically well recognized on radiographs, but differentiation between benign and malignant cartilaginous lesions can be difficult both for the radiologist and for the pathologist. Diagnosis is based on a combination of clinical, radiological and histological findings. While treatment of benign lesions does not require surgery, the only curative treatment for chondrosarcoma is resection. This article (1) emphasizes the update of the WHO classification and its diagnostic and clinical effects; (2) describes the imaging features of the various types of cartilaginous tumors, highlighting findings that can help differentiate benign from malignant lesions; (3) presents differential diagnoses; and (4) provides pathologic correlation. We attempt to offer valuable clues in the approach to this vast entit

Nursing Escape Room UAH: motivation to learn in the biochemistry laboratory

In recent years, Escape Room-type games have gained popularity as a way to motivate students to become more actively involved in their learning. The overall objective of the proposed activity is to promote students' intrinsic motivation and, in turn, meaningful learning. For this purpose, we implemented the game in our laboratories. The first year students of the degree in Nursing participated in the Nursing Escape Room UAH. We chose a situation reviewed in the theoretical-practical contents of the Biochemistry subject they were studying. Our aim was to achieve significant learning through overcoming challenges and collaborative work. After the implementation of the activity, we assessed it. The participating students felt that the activity: i) had helped them to learn and understand the subject; ii) had been a fun and different experience when it came to understanding the content; iii) had been a motivating experience; and iv) they liked the fact that it was carried out in a team. In addition, these students obtained a higher average score and pass rate on the learning assessment test than those who had not participated in the game. The instructors involved also highlighted that the activity was a motivating and different way of learning and recommended its continuation. Altogether, we can conclude that the Nursing Escape Room UAH game has been a motivating experience in the Biochemistry laboratory for both students and instructors. We anticipate that the activity may improve the quality of the teaching-learning process.Universidad de Alcalá. Vicerrectorado de Innovación Docente y Transformación Digita

Impact of Activity-Oriented Propioceptive Antiedema Therapy on the Health-Related Quality of Life of Women with Upper-Limb Lymphedema Secondary to Breast Cancer—A Randomized Clinical Trial

Alterations derived from lymphedema in the upper-limb secondary to breast cancer-related lymphedema (BCRL) decrease the health-related quality of life (HRQoL), but there is limited evidence of the impact of the different interventions on it. The aim of this research was to compare the effect of conventional treatment with another treatment based on Activity-Oriented Antiedema Proprioceptive Therapy (TAPA) on HRQoL in women diagnosed with BCRL.This research was funded by the Call for research and innovation projects in the field of primary care, regional hospitals and high-resolution hospital centres of the Public Health System of Andalusia in 2021 by the Progreso y Salud Foundation, of the Ministry of Health and Families of the Junta de Andalucía, with EXP. No.: AP-0160-2021-C2-F2. He has also been awarded a scholarship by the Professional Association of Occupational Therapists of Extremadura (COPTOEX) (Spain) call 2020 and awarded a financial contribution from the Research Group in Primary Health Care of Aragon (GAIAP-B21-17R group), recognized and financed by the Government of Aragón (Spain) and by Feder Funds “Another way of making Europe”

Análisis y cartografía de peligrosidad geológica en el litoral de Ceuta

La Ciudad Autónoma de Ceuta posee un litoral con una longitud de más 25 km donde se concentra gran parte de su población. En estas costas se describen numerosos procesos geológicos que conllevan una importante peligrosidad potencial para la vida humana e infraestructuras. El objetivo de este trabajo es describir y analizar cada uno de estos procesos mediante la construcción de mapas de peligrosidad de inundaciones y avenidas fluviales; deslizamientos y caída de rocas; y temporales, tsunamis y ascenso del nivel del mar. Aunque aproximadamente sólo el 15% del territorio de Ceuta se encuentra afectada potencialmente por algún tipo de proceso peligroso, hay que destacar que más del 70% de la superficie de su litoral sí se encuentra expuesto. Las zonas consideradas de mayor peligrosidad coinciden con espacios donde se concentran varios tipos de procesos que actúan con grados de peligrosidad alta a muy alta. Son sectores costeros relativamente planos, aunque anexos a zonas más escarpadas, donde desembocan arroyos y barrancos que presentan un comportamiento de marcado carácter estacional.The coastal line of Ceuta is more than 25 km length, where a great amount of population is placed. Along this coast many geological processes have been described and imply a great threat for both human and infrastructure. The aim of this work is to analyse these processes by means of geological hazard mapping focused on flooding and flash flood, landslide and rock fall, storms, tsunamis and sea-level rise. These maps are valuable tools to predict and reduce the response-time with respect to catastrophic natural processes and territorial management. Although approximately only 15% of the Ceuta territory is exposed, more than 70% of its coastal area is exposed to geological hazards. Zones of higher hazard are located where several -high to very high degree- hazard processes could take place even simultaneously. This scenario is mainly found in relatively flat coastal sectors but attached to steep zones, where stream mouths and gorges are placed and display a strong seasonal behaviour
