VAD is associated with increased susceptibility to disease, poor response to vaccination and increased mortality 2, 3. An estimated 250 million preschool-aged children are VAD, with at least 5 million showing clinical signs 1. Vitamin A deficiency (VAD) is one of the most common nutritional disorders in the world. Our results support the use of the calf model for elucidating the impact of nutritional status on mucosal immunity and respiratory viral infection in infants and underline the importance of VA in regulating immunity in the respiratory mucosa. We further show that acute BRSV infection negatively impacts serum and liver retinol, rendering even well-nourished individuals susceptible to VAD. Our results show that VAD calves are unable to respond to the mucosal BRSV-NP vaccine, are afforded no protection from BRSV challenge and have significant abnormalities in the inflammatory response in the infected lung. Here, we evaluated the impact of VAD on the immune response to the BRSV-NP vaccine and subsequent challenge with BRSV. Calves receiving a single, intranasal dose of the BRSV-NP vaccine are partially protected from BRSV challenge. We have previously developed an amphiphilic polyanhydride nanoparticle (NP)-based vaccine (i.e., nanovaccine) encapsulating the fusion and attachment proteins from BRSV (BRSV-NP).
The calf model of BRSV infection is useful to understand the immune response to human RSV infection. Bovine RSV (BRSV) is a primary cause of lower respiratory tract disease in young cattle. Vitamin A deficiency (VAD) is one of the most prevalent nutrition-related health problems in the world and is a significant risk factor in the development of severe respiratory infections in infants and young children. Sin embargo, no sabemos muy bien que pinta aquí un juego como es Tour de France: 2011, un juego que puede estar notoriamente desfasado.Respiratory syncytial virus (RSV) infection is a leading cause of severe acute lower respiratory tract infection in infants and children worldwide. Los últimos juegos que pasan a estar disponibles son J urassic Park, Battlestations: Midway, Drangon´s Lair y Tour de France: 2011.De este modo toca disfrutarlos. Entre otros nos encontraremos el juego de Jurassic Park, toca revivir las viejas glorias y preparar nuestra consola para las largas etapas en casa. Durante el día de ayer, se anunciaba que algunos juegos pasaban a engrosar más la lista de juegos totalmente compatibles con Xbox One a pesar de ser de plataformas anteriores.
Todo ello, gracias a su compatibilidad con el desarrollo de Windows 10. No podía ser de otro modo en la plataforma de Microsoft, la Xbox One, una consola que cuenta con el mayor catálogo retro-compatible del mercado. Como ya sabéis, la locura por la retro-compatibilidad y los juegos de antaño está plagando las consolas de nueva generación.
