Flotar en la viscosidad. Literatura cubana de los 90

Flotar en la viscosidad. Literatura cubana de los 90, is a dissertation that focuses on Cuban literature in the 90s as one of the stages of major changes and literary projections after 1959 in Cuba, as part of Latin American literary developments following the collapse of the Berlin Wall. The late twentieth century in Cuba was a time of fractures and vulnerabilities in different representations of the social subject and his/her circumstances, historically manipulated by the government. As examples of this rupture with the socialist literary canon, I study three authors and their representative works from this period: the poet Reina María Rodríguez, the narrator Pedro Juan Gutiérrez and the poet, narrator and essayist Antonio José Ponte. As I demonstrate in my thesis, their works are able to dialogue with particular and dissimilar voices using original prose fiction, poetry and essayistic elements, mostly absent on the island map during three decades of socialism. Similarly, their books reflect a critical period, damaged paradigms and a new subject that coincides with a novel national imaginary, contrasting with the new man (“el hombre nuevo”) as symbol of the socialist regime. In this regard, I have paid close attention to two major events for the continent after the collapse of the Berlin Wall: the so-called “special period in peace time” and the triumph of neoliberal globalization in the rest of Latin America

Abdominoplasty Marking Instrument

Introduction: Data from the International Society of Aesthetic Plastic Surgery indicate that abdominoplasty is the fourth most common plastic surgery performed worldwide. Several surgical techniques aim to restore the abdominal contour. The indication for the technique used should aim to improve any individual deformity present in the abdomen. Abdominoplasty marking is done using a ruler, protractor, compass, nylon thread, toothpick, pen, and/or methylene blue, according to the surgeon's preference. Here we aimed to produce a surgical instrument that optimizes the abdominoplasty marking procedure. Methods: The study was approved by the ethics research committee. Graphic designs were developed to identify each part of the instrument, a precedence search was performed, and a patent application was requested. Results: We developed an abdominoplasty marking instrument consisting of a horizontal ruler that receives a vertical ruler at its midpoint, two pivotal rulers with a basal protractor, all marked in millimeters, and a central area that allows marking in this region with methylene blue or a pen. Moreover, it acts as a compass and features side pivotal rulers derived from a basal grade protractor. Conclusion: The instrument developed in this study was designed to minimize the amount of material used and optimize abdominoplasty marking time

Development and implementation of a potential coronavirus disease 2019 (COVID-19) vaccine: A systematic review and meta-analysis of vaccine clinical trials.

Background: To date, there is no comprehensive systematic review and meta-analysis to assess the suitability of COVID-19 vaccines for mass immunization. The current systematic review and meta-analysis was conducted to evaluate the safety and immunogenicity of novel COVID-19 vaccine candidates under clinical trial evaluation and present a contemporary update on the development and implementation of a potential vaccines. Methods: For this study PubMed, MEDLINE, and Embase electronic databases were used to search for eligible studies on the interface between novel coronavirus and vaccine design until December 31, 2020. Results: We have included fourteen non-randomized and randomized controlled phase I-III trials. Implementation of a universal vaccination program with proven safety and efficacy through robust clinical evaluation is the long-term goal for preventing COVID-19. The immunization program must be cost-effective for mass production and accessibility. Despite pioneering techniques for the fast-track development of the vaccine in the current global emergency, mass production and availability of an effective COVID-19 vaccine could take some more time. Conclusion: Our findings suggest a revisiting of the reported solicited and unsolicited systemic adverse events for COVID-19 candidate vaccines. Hence, it is alarming to judiciously expose thousands of participants to COVID-19 candidate vaccines at Phase-3 trials that have adverse events and insufficient evidence on safety and effectiveness that necessitates further justification

Native and fermented waxy cassava starch as a novel gluten-free and clean label ingredient for baking and expanded product development

Amylose-free and wild-type cassava starches were fermented for up to 30 days and oven- or sun-dried. The specific volume (ν) after baking was measured in native and fermented starches. The average ν (across treatments) for waxy starch was 3.5 times higher than that in wild-type starches (17.6 vs. 4.8 cm3 g−1). The best wild-type starch (obtained after fermentation and sun-drying) had considerably poorer breadmaking potential than native waxy cassava (8.4 vs. 16.4 cm3 g−1, respectively). The best results were generally obtained through the synergistic combination of fermentation (for about 10–14 days) and sundrying. Fermentation reduced viscosities and the weight average molar mass led to denser macromolecules and increased branching degree, which are linked to a high loaf volume. The absence of amylose, however, was shown to be a main determinant as well. Native waxy starch (neutral in taste, gluten-free, and considerably less expensive than the current alternatives to cassava) could become a new ingredient for the formulation of clean label-baked or fried expanded products
