Clinical Evaluation of Fluido Compact: A New Intravenous Fluid Warmer  [PDF]
Juan M. Zaballos, Lisette De la Cruz
Open Journal of Anesthesiology (OJAnes) , 2017, DOI: 10.4236/ojanes.2017.74010
Abstract: Unintended peri-operative hypothermia is very common in surgical patients and is associated with adverse outcomes. Perioperative use of forced-air and intravenous fluid warmers is recommended for hypothermia prevention. This study evaluated the ease of use of Fluido Compact, a new fluid warming device, and its ability to help as part of the intraoperative patient temperature management. It was used in 36 patients undergoing scheduled surgery at risk of hypothermia under regional, general or combined anesthesia, of more than one hour duration and with a predicted intravenous fluid administration of at least 1000 ml. The fluid warmer is very easy to set up. The disposable cassette has a very low (3 ml) priming volume and it is easy to handle and to place inside the warming module. Once connected to the main power outlet, it is ready to deliver fluid at target temperature in just a few seconds. Control panel is intuitive, and the one button operation system makes it safe and convenient. The combination of peri-operative patient surface warming with Mistral-Air forced-air warming system and intravenous fluid warming with Fluido Compact, that allowed the administration of IV perfusions at body temperature at the rate needed thus avoiding heat loss, helps to maintain intraoperative core temperature between 36.4°C and 36.8°C. A group of patients undergo a variety of surgical procedures with neuraxial, general or combined epidural-general anesthesia.
Bioassay Directed Identification of Royal Jelly’s Active Compounds against the Growth of Bacteria Capable of Infecting Cutaneous Wounds  [PDF]
Mariana C. Garcia, Mónica S. Finola, Juan M. Marioli
Advances in Microbiology (AiM) , 2013, DOI: 10.4236/aim.2013.32022

Antibiotic-resistant bacteria continue to be of major health concern world-wide. Thus, it is of great interest to study the biological properties and determine active compounds in natural products likely to be used as new health remedies. Therefore, the main objective of this work is to test the antibacterial activity of royal jelly samples, defatted royal jelly samples and their ethyl ether extracts against bacteria capable of infecting cutaneous wounds in humans and animals, and to recognize major bioactive compounds by using bioassay directed identification. The microorganisms used in the study were Staphylococcus aureus (including Methicillin-resistant and sensitive strains), Staphylococcus epidermidis, Micrococcus luteus, Streptococcus uberis, Enterococcus faecalis, Pseudomonas aeruginosa, Escherichia coli, and Klebsiella pneumoniae. The activity of royal jelly samples to inhibit bacterial growth was assessed by using well-difussion tests. Direct bioautography was used to identify bioactivity, and uv-visible spectroscopy and gas chromatography-mass spectrometry were used to identify bioactive compounds. Overall, royal jelly samples showed higher growth inhibition activity against Gram positive bacteria as compared to Gram negative bacteria. The growth of bacterial strains belonging to the Enterococcus and Streptococcus genders was less affected by the presence of royal jelly than bacterial strains of the Staphylococcus gender did. Compounds with antibacterial activity were found in the ethyl ether extract of royal jelly samples. 10-hydroxy-2-decenoic acid was the major component identified in the purified fraction obtained by bioassay guided fractionation of the ethyl ether extract. In conclusion, bioactivity of royal jelly samples is mainly due to their 10-hydroxy-2-decenoic acid content.

Factores tecnológicos, legales y documentales de la preservación documental digital
Voutssas M., Juan;
Investigación bibliotecológica , 2009,
Abstract: today's problematic about the huge world production and accumulation of information conformed as digital or electronic documents is analyzed, as well as the problems related to the risk or possible loss of such information and the different strategies for insuring its preservation. factors which work in favor or against long term preservation of digital documents are studied and established, particularly those of technological, legal or documentary nature.
Factores culturales, económicos y sociales de la preservación documental digital
Voutssas M., Juan;
Investigación bibliotecológica , 2011,
Abstract: the current problem of the huge global production and accumulation of information in the form of electronic or digital documents, and the problem caused by the loss of that information and the possible preservation are analyzed. factors that affect the preservation of long-term digital documents are established and studied in detail, in particular the cultural, economic and social ones.
Preservación documental digital y seguridad informática
Voutssas M., Juan;
Investigación bibliotecológica , 2010,
Abstract: today's problematic situation with respect to the world production and accumulation of information in electronic or digital document format is analyzed, as well as the problems associated with access to their content, especially via the internet since this could imply the risk of losing such information. the risks, threats, vulnerabilities, etc. which affect this information are determined, as well as diverse strategies to establish computer security, and the relation this has with reliable preservation of information. the factors which have a bearing in favor of or against the security of digital documents, are studied in detail.
Preservación del patrimonio documental digital en el mundo y en México
Voutssás M., Juan;
Investigación bibliotecológica , 2012,
Abstract: the paper discusses the evolution of the main projects of digital document preservation globally, highlighting its premises and most relevant elements, as well as various strategies that have been developed for its possible preservation. from this, is a proposal for a possible national-level strategy to begin developing digital document preservation projects in a coordinated and harmonious way aimed at this purpose.
El texto en representación: La escritura visual en Exit de Gonzalo Mu?oz
Herrera M,Juan;
Acta literaria , 2009, DOI: 10.4067/S0717-68482009000100008
Abstract: this article examines the poetic writing by gonzalo mu?oz to show that his poetry is connected to the image culture. the texts by mu?oz, in regard to their composition and references therein, and the poetic chilean tradition, represent the crisis of a print culture and the advent of a new image regime in the context of the chilean culture of the 1980s.
Hacia una estética de la desaparición en la poética de Tomás Harris
Acta literaria , 2005, DOI: 10.4067/S0717-68482005000100002
Abstract: this article focuses on the poetry of tomas harris (1956), from the image culture perspective, assuming this approach has been scarcely applied in previous works, with only a few exceptions. moreover, this work studies the form in which some author?s texts are culturally determined by this turning point in the chilean poetic tradition, taking into account some rhetoric elements, which evidence the presence of this new paradigm
La nueva novela de Juan Luis Martínez: Poesía protohipertextual en el contexto de la videósfera
Herrera M,Juan;
Acta literaria , 2007, DOI: 10.4067/S0717-68482007000200002
Abstract: this article examines the poetry of juan luis martinez, which constitutes a complex representation system where the limits of a book are shifted from the sphere of writing to the sphere of images. this fact determines a significant work in the context of chilean poetry in the 80s. the rhetoric elements and other operations which characterize the aesthetics of martinez's work lead us to posit that this literature announces the new ways to support the text: the hypertext.

Carretero Zamora,Juan M.;
Cuadernos de historia de Espa?±a , 2003,
Abstract: the "colectorías"; were basic institutions of the pope's finances. there was a "colectoría"; in each european catholic kingdom, chiefs of which were those belonging to the habsburg monarchy: spain, naples and portugal. the most important was the spanish "colectoría";, which included the kingdoms of castile and aragon. this "colectoría"; reached its definitive configuration in the times of the papal nuncio in spain, giovanni poggio, an important person who held high offices in rome's finances.
