Nuevas terminaciones para nuevas realidades: performatividad, afiliación y atenuación en la comunidad de habla LGTBI
2021
Este artículo presenta un estudio sobre las terminaciones -i/-is y -e/-es en la comunidad de habla LGTBI. La motivación de esta investigación viene de la representación del género no binario en la lengua española, marcado recientemente por las terminaciones en -e, que además es utilizado para crear un plural inclusivo que evite el masculino genérico. En la misma línea, se han detectado usos, dentro de la comunidad de habla LGTBI, de otro grupo de terminaciones (-i/-is) que parecen anular la distinción de género. Los datos han sido extraídos de una encuesta sociolingüística elaborada por el autor de este trabajo. En la parte sociolingüística se pretende perfilar el tipo de usuario de estas t…
Clinical pathways for fragility fractures of the pelvic ring: personal experience and review of the literature
2014
AbstractFragility fractures of the pelvic ring (FFP) are increasing in frequency and require challenging treatment. A new comprehensive classification considers both fracture morphology and degree of instability. The classification system also provides recommendations for type and invasiveness of treatment. In this article, a literature review of treatment alternatives is presented and compared with our own experiences. Whereas FFP Type I lesions can be treated conservatively, FFP Types III and IV require surgical treatment. For FFP Type II lessions, percutaneous fixation techniques should be considered after a trial of conservative treatment. FFP Type III lesions need open reduction and in…
Steroidal saponins from Asparagus acutifolius.
2007
Abstract Six new steroidal saponins ( 1 – 6 ) were isolated from the roots of A. acutifolius L., together with a known spirostanol glycoside ( 7 ). Their structures were elucidated mainly by extensive spectroscopic analysis (1D and 2D NMR, FABMS and HRESIMS). Compounds 4 – 7 demonstrated antifungal activity against the human pathogenic yeasts C. albicans , C. glabrata and C. tropicalis with MICs values between 12.5 and 100 μg/ml.
Steroidal saponins from Smilax medica and their antifungal activity.
2005
Three new steroidal saponins (1-3) were isolated from the roots of Smilax medica, together with the known disporoside A (4). The structures of the new compounds were elucidated mainly by extensive spectroscopic analysis (1D and 2D NMR, FABMS, and HRESIMS). Compounds 1, 2, and 4 demonstrated weak antifungal activity against the human pathogenic yeasts Candida albicans, C. glabrata, and C.tropicalis, with MIC values between 12.5 and 50 microg/mL.
Bioactive Steroidal Saponins from Smilax medica
2006
Two new spirostanol saponins ( 1 and 2) were isolated from the roots of Smilax medica, together with the known smilagenin 3-O-beta-D-glucopyranoside (3). Their structures were determined by spectroscopic methods including 1D- and 2D-NMR experiments. Compounds 1 and 2 exhibited antifungal activity against the human pathogenic yeasts Candida albicans, C. glabrata and C. tropicalis (MICs between 6.25 and 50 microg/mL) whereas 3 was inactive.
Steroidal saponins from the roots of Smilax aspera subsp. mauritanica
2008
Two new steroidal saponins (1, 2) were isolated from the roots of Smilax aspera subsp. mauritanica (POIR.) ARCANG. (Liliaceae), together with the known curillin G (3), asparagoside E (4), asparoside A (5), asparoside B (6) and the phenolic compound resveratrol (7). Their structures were established mainly on the basis of 600 MHz 2D-NMR spectral data. 3 exhibited antifungal activity against the human pathogenic yeasts Candida albicans, C. glabrata and C. tropicalis (minimum inhibitory concentrations of 25, 25 and 50 microg/ml, respectively) whereas the other compounds were inactive.
Successful use of impella CP through femoral access in a patient with bilateral iliac and aortic endoprosthesis in the setting of cardiogenic shock
2019
We report the case of a 67-year-old male, with previous history of severe peripheral vascular disease (abdominal aorta aneurism and bilateral iliac stenosis) requiring the implantation of 3 endoprostheses 7 months ago (Figure 1(A)), and previous myocardial infarction 10 years ago. The left ventricular ejection fraction (LVEF) was preserved at last control (58%). The patient was referred for acute coronary syndrome complicated with pulmonary oedema and cardiogenic shock. Echocardiography showed a severe impairment of LVEF (18%) and the patient was transferred to cathlab for emergency percutaneous coronary intervention (PCI). Coronary angiography via right femoral 7Fr access showed a chronic …
Fruit Colour Preferences of Redwings (Turdus iliacus): Experiments with Hand-Raised Juveniles and Wild-Caught Adults
2004
Certain fruit colours and their contrast with the background coloration are suggested to attract frugivorous birds. To test the attractiveness of different colours, we performed three experiments in laboratory with controlled light conditions. In the first two experiments, we studied the fruit colour preferences of naive juvenile redwings. In the third experiment, we continued to investigate whether the contrast of the fruit colour with the background coloration affects the preference of both naive juveniles and experienced adult redwings. In the first experiment, juvenile birds preferred black, UV-blue and red berries, to white ones. In pairwise trials, a new set of juveniles still preferr…
Prospero hierae (Hyacinthaceae), a New Species from Marettimo Island (Sicily)
2009
A new species, Prospero hierae C. Brullo, S. Brullo, Giusso, Pavone & Salmeri (Hyacinthaceae), from Island of Marettimo (Egadi Archipelago, Sicily) is described and illustrated. Its chromosome number (2n = 14), leaf anatomy and ecology are examined. This small species with glaucous, adaxially flat leaves is closely related with the taxa belonging to the Prospero autumnale group and, in particular, it shows more affinities with P. corsicum, P. pulchellum and P. minimum.
Cytotoxicity of medicinal plants of the West-Canadian Gwich׳in Native Americans towards sensitive and multidrug-resistant cancer cells
2015
Abstract Ethnopharmacological relevance Traditional medicine of the Native Americans has a long tradition of medicinal plants, which also influenced modern oncology. For instance, podophyllotoxin the active ingredient of Podophyllum peltatum L. (Berberidaceae) used by Native Americans to treat warts led to the development of etoposide and teniposide. In the present investigation, we studied 10 medicinal plants used by the Gwich׳in First Nation of West-Canada, which have been used against diverse diseases including cancer. Material and methods Sensitive and multidrug-resistant (MDR) tumor cell lines expressing various ATP-binding cassette (ABC) transporters (P-glycoprotein/ ABCB1/MDR1 , MRP1…
