Alkaloids of Phaedranassa dubia (Kunth) J.F. Macbr. and Phaedranassa brevifolia Meerow (Amaryllidaceae) from Ecuador and its cholinesterase-inhibitory activity
Alzheimer's disease is considered the most common cause of dementia and, in an increasingly aging population worldwide, the quest for treatment is a priority. Amaryllidaceae alkaloids are of main interest because of their ...
Alkaloid profile in wild autumn-flowering daffodils and their acetylcholinesterase inhibitory activity
Amaryllidaceae alkaloids are secondary metabolites with interesting medicinal properties. Almost every Narcissus species can synthesize them and constitute an excellent source for their isolation and study. Several ...
A topical microemulsion for the prevention of allergic rhinitis symptoms: results of a randomized, controlled, double-blind, parallel group, multicentre, multinational clinical trial (Nares study)
Background: Since barrier protection measures to avoid contact with allergens are being increasingly developed, we assessed the clinical efficacy and tolerability of a topical nasal microemulsion made of glycerol esters ...
Protective barrier properties of Rhinosectan® spray (containing xyloglucan) on an organotypic 3D airway tissue model (MucilAir): results of an in vitro study.
Background: To evaluate barrier protective properties of Rhinosectan® spray, a medical device containing xyloglucan, on nasal epithelial cells (MucilAir). Methods: MucilAir-Nasal, a three-dimensional organotypic (with ...
Tomato UDP-glucose sterol glycosyltransferases: A family of developmental and stress regulated genes that encode cytosolic and membrane-associated forms of the enzyme
Sterol glycosyltransferases (SGTs) catalyze the glycosylation of the free hydroxyl group at C-3 position of sterols to produce sterol glycosides. Glycosylated sterols and free sterols are primarily located in cell membranes ...
Assessment of dead-end ultrafiltration for the detection and quantification of microbial indicators and pathogens in the drinking water treatment processes
A safe water supply requires distinct treatments and monitoring to guarantee the absence of pathogens and substances potentially hazardous for human health. In this study we assessed the efficiency of the dead-end ...
Trois cas de gynandromorphisme chez Sergentomyia minuta (Diptera, Psychodidae) dans la Péninsule Ibérique
Three gynandromorphe specimens of Sergentomyia minuta have been identified among sandflies captured in North-East Spain. The simultaneous presence of more or less modified male genitalia and of fome female structures were ...
The lipopolysaccharide of Aeromonas spp: structure-activity relationships
Marine microorganisms, including Aeromonas, are a source of compds. for drug development that have generated great expectations in the last decades. Aeromonas infections produce septicemia, and ulcerative and haemorrhagic ...
Xyloglucan, Hibiscus and Propolis for the prevention of Urinary Tract Infections: results of in vitro studies
Aim: To assess the properties of a medical device containing xyloglucan, propolis and hibiscus to create a bioprotective barrier to avoid the contact of uropathogenic Escherichia coli strains on cell walls in models of ...
2010, Any Internacional de la Biodiversitat
El Conveni per a la Diversitat Biològica (CBD) de les Nacions Unides ha declarat l'any 2010 com a Any Internacional de la Biodiversitat. Durant tot l'any se succeiran activitats de tota mena per difondre la problemàtica ...
Emerging roles for conjugated sterols in plants
In plants, sterols are found in free form (free sterols, FSs) and conjugated as steryl esters (SEs), steryl glycosides (SGs) and acyl steryl glycosides (ASGs). Conjugated sterols are ubiquitously found in plants but their ...
Adiciones al catálogo florístico del delta del Ebro (Tarragona, España)
[eng] A list of 20 new records of vascular plants for the Ebro river delta (Tarragona province, Spain) is presented. The occurrence of Tamarix boveana Bunge and Carex laevigata Sm. is of particular chorologic significance. ...

Ultrastructure of digenean trematode eggs (Platyhelminthes: Neoophora): A review emphasizing new comparative data on four European Microphalloidea
Despite their tremendous diversity and their medical and veterinary importance, details of egg ultrastructure among the digenean trematodes has been studied rather little. The available literature is spread over several ...
Factors influencing the presence of sand flies in Majorca (Balearic Islands, Spain) with special reference to Phlebotomus pernicious, vector of Leishmania infantum
Background: Although the Mediterranean island of Majorca is an endemic area of leishmaniosis, there is a lack of up-to-date data on its sand fly fauna, the last report dating from 1989. The aim of the present study was to ...
New Data on Pterygodermatites ( Pterygodermatites) plagiostoma Wedl, 1861 (Nematoda, Rictulariidae) Parasite of the Algerian Hedgehog Atelerix algirus Linnaeus, 1758 (Eulipotyphla: Erinaceidae) from the Canary Islands
A redescription of the rictulariid nematode Pterygodermatites (Pterygodermatites) plagiostoma Wedl, 1861, is made by means of light and scanning electron microscopy, including the first data on male specimens. The morphologic ...
Sobre un Verbascum no iberico
Verbascum creticum (L.) Cav., como novedad provincial que lo sería también peninsular. Anteriormente, BENEDÍ and J. M. MONTSERRAT (Collect. Bot. Barcelona 16:110,1985) han considerado que dicha especie no es ibérica.
