The formulations of the drug of choice for its treatment have a low residence time and bioavailability at the site of infection. The aim of this study was to prepare and characterize mucoadhesive films of chitosan and polygalacturonic acid by the “Solvent-Casting” technique loaded with nystatin as a sustained release system for the oral cavity. The films obtained were characterized to determine their morphological characteristics, adhesion capacity, and degree of swelling and release profile of the drug. The morphology of the films was determined by scanning electron microscopy, the interaction between the polymers was determined by infrared spectroscopy, thermogravimetric analysis, and differential scanning calorimetry, additionally, its antimicrobial activity against two Candida species was tested. The obtained films showed mucoadhesion capacity and a sustained release of the drug explained by the Korsemeyer-Peppas model, also a significant antimicrobial activity was found. These findings suggest that chitosan-based films are a possible nystatin release system for the oral cavity.</em></p> 2021-01-15T00:00:00+00:00 Copyright (c) 2021 Efrain Armenta Rojas, Jose Manuel Cornejo Bravo, Aracely Serrano Medina , Eduardo Alberto López Maldonado , Amelia Olivas Sarabia, Nydia Alejandra Castillo Martínez, Ayla Carolina Vea Barragán https://recit.uabc.mx/index.php/revista/article/view/tlei1 Design and implementation of a pumping system for salt extraction based on photovoltaic energy 2021-01-08T20:19:40+00:00 Jorge Armando Ojeda Sánchez jojeda1@ucol.mx Erik Eduardo Vázquez Fernández erick_vazquez@ucol.mx Ramón Antonio Félix Cuadras rfelix@ucol.mx Alejandro Regalado Escobedo regalado@ucol.mx Arturo Rincón Pulido rinconpulido@ucol.mx <p>Sea salt production in Mexico uses traditional systems for filling, brine treatment, and storage. Access to the electrical distribution network is generally not available due to the salinity of the soil. In the Laguna de Cuyutlán in the southwest of the state of Colima, Mexico, the production process requires that the pumping of seawater be carried out by means of generator equipment for use in motor pumps at specific hours of the morning, due to the high solar radiation exposure. In the present work, an isolated photovoltaic system with battery backup applied to the pumping systems is developed, controlled semi-automatically by using the Arduino board. The goal is to improve industrial infrastructure and increase the efficiency of traditional salt production processes. From the implementation of an isolated photovoltaic system (IPVS), the process of pumping seawater is improved in a semi-automatic way, compared to the traditional process, avoiding the expense of fuel in generator equipment.</p> 2021-01-25T00:00:00+00:00 Copyright (c) 2021 Jorge Armando Ojeda Sánchez, Erik Eduardo Vázquez Fernández, Ramón Antonio Félix Cuadras, Alejandro Regalado Escobedo, Arturo Rincón Pulido
