Ultravio!et-B radiation absorbing capacity of leaf hairs, -Physiol, Plant, 86:414-418,Pubescence layers with their native structure and orientation were isolated from the leaves of Olea europaea L, and Otea chrysophylla L, They were almost transparent in the visible, but considerable absorptance was evident in the ultraviolet-B region (UV-B), with maximum at 310 nm, Methanolic extracts of hairs from Olea and a variety of other pubescent species consistently showed the existence of UV-screening pigments, Ahsorptance of trichomes varied, but a trend towards more effective UV-B radiation attenuation in the sub-alpine Verbascum species may be claimed. In all cases, pigments were located within hair cells and in Olea they were characterized as phenolics with considerable flavonoid contribution. It is suggested that leaf hairs, besides other functions, may constitute a shield against UV-B radiation.

BackgroundThe onset of a major depressive episode is experienced by a large number of women in the weeks or months following delivery. Postpartum depression may deem those women experiencing it incapable of taking care for themselves, their family and their infants, while at the same time it could negatively affect their quality of life. The present study assessed the quality of life of a sample of mothers in Greece, in order to investigate the association between postpartum depression and quality of life (QoL).Methods145 women in a Private-General Obstetrics and Pediatric Clinic in Greece completed the Edinburgh Postnatal Depression scale (EPDS) and SF-36 questionnaire on the third and fourth day after delivery (caesarean or normal childbirth). The data were analyzed using SPSS version 17.0. Linear and logistic regression analysis was performed in order to find the independent factors related to the quality of life and postpartum depression symptoms.Results9.9% of the participants experienced postpartum depression symptoms. Significant associations were found between the place of residence and symptoms of postpartum depression, and more specifically, women outside of Attica indicated higher levels of postpartum depression symptoms (p = 0.008) than women living in Attica. The level of education was also found to be significantly associated with postpartum depression symptoms, since women with Primary and Secondary education experienced higher levels of postpartum depression symptoms (p = 0.005) than those with a tertiary education. Concerning quality of life, women with postpartum depression symptoms scored 24.27 lower in «Role-Physical», 15.60 lower in «Bodily pain», 11.45 lower in «General Health», 14.18 lower in dimension of «Vitality», 38.25 lower in Role – Emotional and 16.82 lower in dimension of mental health, compared to those without depression symptoms.ConclusionPostpartum depression symptoms are associated with the quality of life of women after pregnancy, and therefore constitute a powerful predictor of the quality of life. Health care professionals should provide individualized care for the prevention and treatment of Postpartum Depression symptoms in order to help women improve their quality of life.
