The general objective of this thesis is to develop and investigate microfluidic devices to be applied to the culture of eukaryotic cells and the study of fluids in porous media. During this thesis work, microfluidic devices have been successfully developed, which were applied in the culture of both adherent and suspended cells and in the analysis of flow in porous media. A new method of manufacturing microfluidic devices has been developed the manufacturing of microdevices possible in the country (and in other developing countries), without the need of access to a cleanroom, which will make the massification of microfluidic possible.
A meritocracy is a society in which success and failure belong to those who 'deserve' them. What you get depends directly on the decisions you make and on archiving the right balance between responsibility and audacity. Yet, a key point is frequently overlooked: identical circumstances, means, and opportunities must be guaranteed for meritocracy to make sense. In this article, Sol Minoldo highlights the danger of the reverse the logic, that is, assuming that the different achievements are reliable proof that some made more effort than others, and discusses what a higher performance might actually reflect.
The JOSHA Team is very pleased to share information with you about our Demetrios Prize 2020. The International Academy of Sciences, Humanities, and Arts (IASHA e.V.), with the support of the BioThera-Roland Mertelsmann Foundation, will award three prizes of 500 euros for the categories BACHELOR, MASTER and DOCTOR THESIS. Our editors will make the selection and the theses of the winners will be published in JOSHA and can be referenced with their DOI number! The “Journal of Science, Humanities, and Arts – JOSHA” has been initiated to create a novel internet platform to access the broad diversity of important discoveries and creativity in the fields of Science, Humanities, and Arts. At JOSHA we believe, that "Knowledge that is not communicated is wasted knowledge".
This is one of many Articles El Gato y La Caja shares with the JOSHA Journal. This time in the field of Life and Sciences Ezequiel Calvo presents an incredible story about Henrietta Lacks, a woman that changes and improve forever all the labs around the world. Shortly after being diagnosed (and without her consent) a small piece of Henrietta Lacks´ tumor was cut out and put it in a glass dish. Surprisingly, her uterine-cervical cancer cells had the ability to grow indefinitely. In this single immoral act, the beginning of a revolution in cell biology had occurred. On October 4, 1951, Henrietta Lacks died without knowing that a little piece of her was going to be found in almost every laboratory in the world that uses cell culture. This is her story.
Languages that attribute a grammatical gender to objects might induce a biased effect on how these objects are perceived. In a famous study by Lera Boroditsky, a list of 24 reverse-gendered nouns was prepared in Spanish and German. In each language, half of them were feminine and half masculine. Native Spanish and German speakers were shown the nouns, written in English, and asked about the first three adjectives that came to their minds. For instance, the word key is masculine in German. German speakers described keys as hard, heavy, metallic, and useful. In contrast, Spanish speakers described them as golden, small, adorable, shiny, and tiny. Conversely, the word bridge is feminine in German, and German speakers described bridges as beautiful, elegant, fragile, pretty, quiet, slender. Spanish speakers said that they were big, dangerous, strong, resistant, imposing, and long.
Perfil Clinico de Pacientes con Trastornos de la Conducta Alimentaria - Clinical Profile of Patients with Eating Disorders
The main objective of the present theoretical review is to provide a detailed description of the clinical profile of subjects suffering from an Eating Disorder. To this end, documentary observation and content analysis were used as data collection and systematization techniques, respectively. The above was done by reviewing a total sample of 49 electronic articles that gave an account of the incident factors in eating disorders. The results obtained indicate the relevance of cognitive distortions of body image in the maintenance and prognosis of ACTs. Taking into account the aforementioned, a review of the main theoretical contributions describing the clinical profile of patients with eating disorders will be carried out. In particular about Anorexia Nervosa (AN) and Bulimia Nervosa (BN).
Correlation between ultrasound Diagnosis of Chorionicity with postpartum placental Histopathology and the Risk of adverse perinatal Outcomes in monochorionic twin Pregnancies
The objective of this study is to determine if non-correlation between the ultrasound diagnosis of chorionicity with a postpartum placental histopathological study is a risk factor for presenting adverse perinatal outcomes, assumed fact, but it has not been registered yet in the current literature. MATERIALS AND METHODS: transversal and retrolective study. Twin pregnancies cases treated in the HUS between 2014-2019 were evaluated. Cases with a postpartum placental histopathological study report, concerning monochorionic twin pregnancy, were included. The ultrasound / histopathological diagnostic correlation of chorionicity was evaluated between initial obstetric ultrasound and placental study. Stratified sampling analysis was performed according to the presence or absence of diagnostic correlation and according to the time of the obstetric ultrasound.
PENSAR CON OTROS, La Era de la Posverdad - Las palabras y las cosas, Capitulo 1- THINKING WITH OTHERS: A survival guide in times of post-truth
Below is the introduction, preface and first chapter of the book Pensar con otros. Una guía de supervivencia en tiempos de posverdad (Thinking with others. A survival guide in times of post-truth), published in 2018. A book that aims to be a starting point to break down post-truth into its main components through concrete examples, as a way to better prepare ourselves to identify the structures that foster post-truth and thus achieve, together, survival and victory. Post-truth allows facts to become facts as long as they fit the desires of each group, of each tribe. Each of these groups develops its own narrative with a language that privileges the capacity to provoke emotions, and pushes those emotions to build landscapes only accessible to those who share the way of looking at them. This discontinuity in the landscape is a threat to the existence and development of meaningful human bonds, to our coexistence as a species on this planet and, thus, to our survival.
The Effect of Cervical Cancer Surgical Management on Sexual Function in a northeastern colombian Hospital
Female sexual function is one of the determinants factors for female health. The objective of this study is to evaluate the effect of surgical management on female sexual function in patients with cervix cancer six months after the intervention. MATERIALS AND METHODS: Prolective cohort in which we applied in a voluntary way the Female sexual function index (FSFI) n women with a diagnosis of cervix cancer and surgical management with active sexual life treated in Hospital Universitario de Santander (Colombia) in 2019.
Evaluation of the Determinants of Magnesemia in Patients with Preeclampsia with severe Features treated according to 2013 Task force Figo protocol
Corresponding Author: Katherine Bahamon Florez. The therapeutic schemes with magnesium sulfate for the treatment to severe criteria preeclampsia haven't had changes since the last century; they don't take into account the medicine's pharmacokinetics, resulting in variations on the Magnesium's serum levels. There is local research which evidenced that the use of current schemes is associated with subtherapeutic serum levels. Looking at factors that influenced creatinine's serum levels, body mass index (BMI) and the therapeutic scheme used. In this prospective study made in a third level hospital. We studied 90 pregnant women diagnosed with severe criteria preeclampsia, who were treated in the University Hospital of Santander from 2018 to 2019 and who started a prophylactic scheme with magnesium sulfate by 24 hours.
