Research ArticleOpen accessIn the author namesProsthetic Knee Mechanism Using a Double Locking System as a Safety MeasureEicarl Saynes Vazquez, Esther Lugo GonzálezThe design of a four-link knee prosthesis mechanism with two locking systems activated during the flexion/extension phase is presented. The first is geometric, totally mechanical and activated by the user's weight. The second is variable and is activated automatically when walking on irregular or special surfaces is required. The links' dimensions were selected using the differential evolutionary optimization algorithm to … …Journal of Mechatronics and Robotics, Vol. 8, Issue 1 · 12 Feb 2024 · 5,706 accessesView PDFCite
InvestigationOpen accessIn the author namesComparison of Green Roof Model Predictions with Experimental DataSergio Quezada-García, Manuela Azucena Escobedo-Izquierdo, Juan José Ambriz-García et al.In this study, the results of a green roof model are presented and compared with experimental data. Good agreement between simulation and experiment were found for different experimental conditions that were carried out in a controlled environment laboratory. The study of green roof heat transfer processes is important because it allows a better thermal design in buildings; the use of … …Energy Research Journal, Vol. 6, Issue 1 · 14 Jul 2015 · 7,228 accessesView PDFCite
Research ArticleOpen accessIn the author namesCirculation of Multidrug-Resistant (MDR) and Extensively Drug-Resistant (XDR) Mycobacterium Tuberculosis Strains in MexicoCarlos A. Vazquez-Chacon, Armando Martinez-Guarneros, Susana Balandrano Campos et al.Emergence of Extensively Drug-Resistant (XDR) Tuberculosis (TB) is an important public health problem worldwide. In Mexico, the extent of circulation of XDR-TB strains is unknown. Here, the drug-resistance patterns of TB isolates collected in Mexico between 2006 and 2008 were analyzed. Among 137 TB isolates, (58%) were classified as MDR exclusively, (33%) were Pre-XDR and (9%) were assigned as XDR. … …American Journal of Infectious Diseases, Vol. 10, Issue 4 · 7 Jan 2015 · 7,424 accessesView PDFCite
Research ArticleOpen accessIn the author namesHeat Transfer Numerical Analysis of a Thermochemical Solar ReactorA. Vázquez-Rodríguez, J. R. Varela-Ham, R. Avalos-Zuñiga et al.In this study a 2D transient temperature distribution in a one-dimensional thermochemical solar reactor of gas-particles is presented. The gas-particles medium is contained in a reactor where an endothermic chemical reaction of some oxide-metal at high temperature is expected to be occurred. The reactor receives the concentrated solar power on the reactor walls, or directly to the gas-particles medium. As … …Energy Research Journal, Vol. 5, Issue 2 · 6 Jan 2015 · 6,809 accessesView PDFCite
Research ArticleOpen accessIn the author namesANTIOBESITY EFFECTS OF HUMAN SOLUBLE LEPTIN IN MICE NOURISHED WITH A HIGH-FAT/HIGH FRUCTOSE DIETB. Chimal-Vega, N. Paniagua-Castro, J. C. Perez-Rebollar et al.Leptin is a hormone that regulates energy balance. Since its discovery two decades ago, several efforts have been made to fully understand its role in metabolic regulation of feeding behavior, reproduction, glucose homeostasis, immune function, bone formation, lipid metabolism, among others. Its use as a therapeutic option in obese patients is still limited due to the syndrome known as Leptin … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 9 Jul 2014 · 7,388 accessesView PDFCite
Research ArticleOpen accessIn the author namesStructural Consequences of the Polymorphism Q223R in the Human Leptin Receptor: A Molecular Dynamics StudyJonathan P. Carrillo-Vázquez, Brenda Chimal-Vega, Beatriz Zamora-López et al.Leptin Receptor (LEPR) is a component of a signaling pathway related to appetite and energy expenditure. Single Nucleotide Polymorphisms (SNP) of Leptin receptor gene (lepr) have been proposed as possible modulator of adipose tissue and body weight. The main phenomenological consequence reported of these SNPs is the modulation of the LEP-LEPR interaction promoting the weight gain. Particularly, Q223R polymorphism has … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 3 · 23 Sep 2013 · 7,839 accessesView PDFCite
