    Effects of carvedilol on oxidative stress and chronotropic response to exercise in patients with chronic heart failure
    (WILEY, 2005) Castro, P; Vukasovic, JL; Chiong, M; Diaz Araya, G; Alcaino, H; Copaja, M; Valenzuela, R; Greig, D; Perez, O; Corbalan, R; Lavandero, S
    Background: Our previous studies suggest that the increase in heart rate from rest to peak exercise is reduced in patients with chronic heart failure (CHF) and this is associated with increased oxidative stress, as determined by malondialdehyde (MDA) plasma levels.

    Temporal crescent syndrome. Report of one case
    (SOC MEDICA SANTIAGO, 2004) Mery, V; Mellado, P; Valenzuela, R; Luco, C; Huete, I
    The temporal crescent syndrome or half-moon syndrome is a rare mono ocular retrochiasmatic visual field defect that cart be correlated to a lesion along the contralateral parieto-occipital sulcus. This field defect may be missed in automated perimetry. We report a 45 years old man, consulting for sudden loss of the peripheral temporal field in his right eye. The magnetic resonance imaging and the spectroscopy studies confirmed an ischemic lesion on the left anterior occipital cortex. Control imaging studies six months later did not show changes in the lesion.
