OCCLUSION of the central retinal vein causes incomplete haemorrhagic infarction of the inner layers of the retina. Haemorrhagic infarction describes a situation in which the venous backflow of an area of tissue is interrupted. As a result the flow of blood has to stop; ischaemia and resulting increase of vascular permeability lead to retinal oedema and extensive haemorrhages. The central retina...

Traffic-related air pollution is one of the most relevant environmental problems in urban areas. Several cryptogams (i.e., lichens and mosses) vascular species have been employed to monitor since they allow assessment quality a large number sampling sites simultaneously at low cost. In cities, vehicle emissions are frequently major source along with residential energy (for cooking heating), ind...

Information on floral resource costs is fundamental for understanding how selection operates on floral morphology. In this study, I explored the cost of maturing flowers in a self-incompatible population of the ligulate composite Crepis tectorum L. by experimentally manipulating floral investment and then monitoring the response in reproductive effort. Plants on which the heads were removed dur...

These paper deals with 45 taxa, seven of which are new to the Balearic Islands flora: Agrostis capillaris L., Centaurea solstitialis L. Chenopodium strictum Roth, Datura wrigthii Regel, Kickxia elatine (L.) Dumort. subsp. elatine, Ranunculus xatardii Lapeyr. and Senecio inaequidens DC. On the other hand, six taxa [Catananche caerulea L., Centaurea apula Lam., Filago micropodioides Lange, Legous...

A 29-year-old female, an aesthetician, developed occupational allergic contact dermatitis caused by extracts of crude drugs. The results of 48-hour closed patch testing showed positive reactions to the moisturizing cream and oil that she used in her work. This cream and oil included Scutellraria Baicalensis, mugwort (Artemisia vulgaris), and Artemisia capillaris,Gardenia. The results of patch t...
