Título: Enfermedades afectivas y actividad solar: Seguimiento a 16 años / Association between hospital admissions due to affective disorders and solar activity: Analysis of 16 years

Resumo: Background: Exposure to solar activity may be associated with incidence of depressive and manic disorders. Aim: To assess the link between solar activity and appearance of affective disorders. Material and Methods: We examined 1862 clinical records of a psychiatric clinic located in Santiago, Chile. Patients with major depression and manic disorders were included in the study, only when they were admitted at the clinic for the first time. Solar activity was calculated using the Wolf number, which is given by the formula R= K(10g+f), where “g” stands for the groups of sunspots and “f ” is the total number of sunspots. We examined the correlation between annual incidence of hospital admissions and average Wolf numbers for the period 1990-2005, which corresponds to approximately one and half solar cycles of 16 years. Results: A total of 450 medical records corresponding to 299 patients (199 women) with depressive symptoms and 151 patients (73 women) with mania, were analyzed. There was a higher number of admissions for depression during the years with lower solar activity. Admissions due to mania tended to increase in the years with high solar activity. There was a negative correlation between the number of hospital admissions due to depression and solar activity (Spearman r =-0.812, p < 0.01). The association between the latter parameter and admissions due to mania did not reach statistical significance. Conclusions: There is a significant negative association between the rate of hospital admissions due to depressive disorders and solar activity.

Título: Nueva clasificación de los tipos de piel y sus implicaciones en dermatología cosmética / New skin type classification implications in cosmetic dermatology
Fonte: Dermatol. venez;43(4):4-7, 2005. tab.
Idioma: es.
Resumo: A principios de siglo XX se identificaron y descubrieron cuatro diferentes tipos de piel: seca, grasa, combinada y sensible. Desde entonces, la industria de productos para el cuidado de la piel se ha desarrollado hasta producir billones de dólares. Mientras que las formulaciones han evolucionado para obtener una alta sofisticación, lograda a través de extensos estudios de investigación, el gremio dermatológico no ha realizado avances plausibles en la creación de métodos precisos para caracterizar los tipos de piel con el fin de asistir a los pacientes en la búsquedad y utilización de productos que sean apropiados para cada tipo específico de piel. Nuestra experiencia clínica de varios años nos ha llevado a desarrollar un sistema de tipicación de la piel basado en las clasificaciones utilizadas en la actualidad, tales como seca o grasa, sensible o resistente, pigmentada o no pigmentada, con arrugas o sin ellas. Debido a que estas categorías no son mutuamente excluyentes y partiendo de la primera clasificación en cuarto tipos de piel, hemos podido identificar hasta dieciséis tipos diferentes de piel.

Título: Backup compass mechanisms in pigeon orientation with the sun in the zenith

Resumo: The sun is known to guide homing pigeons as a priority cue. The literature indicates that under total overcast conditions pigeons rely on a backup mechanism akin to the magnetic inclination compass for which there is much laboratory evidence in migratory birds. Total overcast conditions are not favorable for orientation research in the State of Sao Paulo, Brazil. The orientation of homing pigeons raised near the tropic of Capricorn was therefore observed around the time of the December solstice, when the sun culminates directly overhead, with a consequent interruption of the sun compass for a short time every day. In these experiments, carried out between 1981 and 1993, local geomagnetic field inclination was -25 degrees Celsius to -29 degrees Celsius 30', so that a functioning magnetic inclination compass should have been available to the birds. Whereas the birds released with sun to zenith angles between 10 degrees Celsius and 30 degrees Celsius were well oriented, both in the morning (99 vanishing bearings) and in the afternoon (143 vanishing bearings), those released with the sun less than 5 degrees Celsius away from the zenith showed random orientation (105 vanishing bearings), with no evidence of an alternative magnetic compass mechanism.
