    , Morpheus counsels Neo to choose between a blue pill that will allow him to continue living a happy existence, or a red pill that will mean facing a potentially harsher reality. When Viagra first appeared back in 1998 as a drug treatment for erectile dysfunction (ED), it similarly promised an exciting future with a younger, sexually vibrant version of yourself. This was of particular importance given the number of men with the condition. The Massachusetts Male Ageing Study (MMAS) demonstrated 40% of 40-year-old men reported ED, and this figure rose to almost 70% in men aged 70 years. Medical professionals like myself refer to the drug as 'sildenafil' – the active compound in the branded drug Viagra – which relaxes blood vessel walls, increases blood flow to the penis and gives a firmer erection. The problem is that in a significant number of men, simply swallowing the pill isn't enough to result in a firm erection. This is understandably disappointing for patients and has led to a high drop-out rate: some studies have found at least 30% don't even get past their first prescription. This means many men stop using a potentially very effective drug which has been available on the NHS since last year. viagra shipped within canada VIAGRA is a prescription drug that works by increasing blood flow to the penis. During arousal, the arteries in the penis relax and widen, allowing more blood flow into the erectile tissues. The veins that carry blood away from the penis become compressed, restricting the blood flow out of the penis. When a man is sexually stimulated, VIAGRA helps the penis fill with enough blood to cause an erection. More blood begins flowing in and less flows out, making the penis larger, and causing an erection. Blood must be able to reach and remain in the erectile tissues to maintain erection quality.

    Viagra works in response to sexual stimulation to increase the blood flow to the penis leading to an erection. Viagra does not result in an erection without sexual stimulation. When a man is aroused, muscles in the penis relax to allow this greater blood flow. Viagra helps to elevate the levels of a substance (cyclic guanosine monophosphate, or c GMP) that causes the tissues to relax, leads to an inflow of blood, and causes an erection with sexual stimulation.

    Una delegación asiática visita la Isla para conocer el trabajo del Banco de Algas, el ITC y Eco Aqua Una expedición de científicos del Instituto Coreano de Ciencia y Tecnología Oceánica (Kiost) ha anunciado la firma de convenios relacionados con la biotecnología azul en Gran Canaria, dado el interés de los estudios de investigación con microalgas para la industria cosmética, alimentaria, farmacéutica y obtener tintes biológicos para el sector textil que se desarrollan en la isla, según comunicó ayer el consejero de Desarrollo Económico, Energía e I D i del Cabildo, Raúl García Brink. Este intercambio de conocimiento entre científicos coreanos y los que trabajan en Gran Canaria ha sido posible tras las gestiones de la Sociedad de Promoción Económica de Gran Canaria (Spegc) dentro de la estrategia que lidera el Cabildo para el desarrollo de la bioeconomía azul en la Isla junto al Instituto Tecnológico de Canarias (ITC) y la Universidad de Las Palmas de Gran Canaria. La delegación recorrió los interesantes trabajos que desarrollan el Instituto Tecnológico de Canarias, el Banco Español de Algas (BEA) y el Instituto Universitario de Acuicultura Sostenible y Ecosistemas Marinos (Eco Aqua), en cuyas sedes en Taliarte estuvieron acompañados también por el cónsul de Asuntos Marítimos y Pesca de Corea en Canarias, Park Ingu. Do-Hyung Kang, el investigador que coordina la investigación para aplicaciones industriales en Kiost, destacó que pese a los casi 15.000 kilómetros que separan Corea de Canarias encontró en la Isla su "segunda casa", ya que ambos territorios insulares comparten la misma inquietud por el desarrollo de una industria que aproveche las múltiples propiedades de las microalgas. Los investigadores coreanos conocieron los procedimientos y los laboratorios para el cultivo de algas tanto del ITC y el Banco de Algas, como el proyecto Seacolors que busca obtener pigmentos para elaborar tintes biológicos para la industria textil. Además, en el Banco Español de Algas, instalado en Telde, pudieron conocer la importante colección de más de 1.600 cepas de la región macaronésica usadas en proyectos de investigación, como Rebeca, de la convocatoria europea Interreg-Mac para identificar el potencial de estos cultivos. Gran Canaria es conocida en la comunidad científica internacional por ser la sede de instituciones científicas, el ITC, el Banco de Algas y el Eco Aqua, que son un referente "para el sector de la biotecnología con algas y la acuicultura por sus servicios de alta especialización y por la importancia de sus proyectos", explicó el consejero.
