Antígenos histo-sanguíneos e infección por rotavirus
2019
La infección por rotavirus es la principal causa de gastroenteritis aguda en niños menores de 5 años en todo el mundo. Su incidencia es similar en países desarrollados y en vías de desarrollo, aunque la mayor mortalidad ocurre en estos últimos. Las vacunas frente a rotavirus han demostrado una gran efectividad en los países industrializados, pero su protección es menor en los países del África subsahariana y Asia. Se ha descrito que los antígenos histo-sanguíneos, presentes en la membrana de los enterocitos, actúan como ligandos para distintos genotipos de rotavirus. Esto podría explicar las diferencias que se observan en su distribución geográfica y la distinta eficacia vacunal de unas áre…
Ultrasound bioeffects in rats: quantification of cellular damage in the fetal liver after pulsed Doppler imaging
2011
Objective To determine whether pulsed Doppler examination of the ductus venosus in rat fetuses could damage exposed tissue. Methods On gestational day 18, the livers of a mean of approximately five fetuses per mother (n = 5.14, SD = 1.6), in a cohort of 35 pregnant female rats, were exposed individually to pulsed Doppler and these were considered the 'exposed group'. The remaining fetuses in each pregnant rat (n = 5.16, SD = 2.1) formed the 'control group'. We tested for 600, 300, 60, 20, 15, 10 and 3 s of exposure of the fetal ductus venosus and the damage was evaluated measuring a cell death index of apoptotic activity at 7 h post-exposure (n = 16). In addition, subgroups of mothers were …
Síntesis diasteroselectiva de sistemas terpénicos con esqueleto de isoespongiano y 25-norescalarano
2012
Esta Tesis describe la síntesis de sistemas terpénicos de tipo isoespongiánico y 25-norescalaránico. En el primer capítulo se describe la síntesis de sistemas diterpénicos con esqueleto carbocíclico de isoespongiano a partir del monoterpeno (S)-carvona. En la misma este monoterpeno es empleado como sintón quiral del anillo C e incorporado al esqueleto tretracíclico de isoespongiano vía una estrategia sintética del tipo C→ABC→ABCD, empleando para su elaboración como etapas clave una reacción de Diels-Alder intramolecular de un 1,3,9-decatrieno para la construcción de los anillos AB y una reacción de metátesis de cierre de anillo de un éter de bis-alilo para la construcción del anillo D. Esta…
Lumbar facet joint stabilization for symptomatic spinal degenerative disease: A systematic review of the literature
2022
Objective: Lumbar spinal degenerative disease (LSDD), unresponsive to conservative therapy, is commonly treated by surgical decompression and interbody fusion. Since facet joint incompetence has been suggested as responsible for the entire phenomenon of spinal degeneration, facet stabilization can be considered as an alternative technique to treat symptomatic spinal degenerative disease. The purpose of this study was to systematically review the literature for studies utilizing lumbar facet joint fixation techniques for LSDD to assess their safety and efficacy. Methods: A systematic literature review was performed following the preferred reporting items for systematic reviews and meta-analy…
Remodeling Pattern of Spinal Canal after Full Endoscopic Uniportal Lumbar Endoscopic Unilateral Laminotomy for Bilateral Decompression: One Year Repe…
2022
Objective: There is limited literature on repetitive postoperative MRI and clinical evaluation after Uniportal Lumbar Endoscopic Unilateral Laminotomy for Bilateral Decompression. Methods: Clinical visual analog scale, Oswestry Disability Index, McNab’s criteria evaluation and MRI evaluation of the axial cut spinal canal area of the upper end plate, mid disc and lower end plate were performed for patients who underwent single-level Uniportal Lumbar Endoscopic Unilateral Laminotomy for Bilateral Decompression. From the evaluation of the axial cut MRI, four types of patterns of remodeling were identified: type A: continuous expanded spinal canal, type B: restenosis with delayed expansio…
Weed vegetation of cereal crops in Tajikistan (Pamir Alai Mts., Middle Asia)
2013
The paper presents results of investigations of weed vegetation conducted in crop fields, in Tajikistan (Middle Asia) - one of the world cradles of the weed flora. The study has been based on 299 phytosociological relevés obtained in various geobotanical regions of the country in 2009-2012. In the examined vegetation patches 469 vascular plant species were noted. Many of the recorded species are widespread weeds. However, there were also some rare and endemics taxa (e.g. Prangos pabularia, P. saraw-schanica and Thlaspidium thlaspi) observed in the sample plots. The collected material presents probably, the majority of the variability among the weed communities of crop cultivations in the Mi…

Uretroplastica con innesto dorsale di mucosa buccale: è ancora il metodo di scelta nella stenosi uretrale a lungo termine? – P18.
2015
INTRODUZIONE E OBIETTIVO DELLO STUDIO: Risultati a lungo termine dell'uretroplastica con innesto dorsale di mucosa buccale e fattori predittivi negativi della metodica. MATERIALI E METODI: Analisi retrospettiva di 27 pazienti sottoposti a uretroplastica con innesto di mucosa buccale (prelievo del graft della guancia di circa 4x2,5 cm) per stenosi uretrale nel periodo 2010-2015 (mediana 42 mesi). Flusso massimo (Qmax), residuo post-minzionale (RPM), ecografia del corpo spongioso uretrale, test IPSS (solo domanda su QoL) e percezione soggettiva allo svuotamento sono stati ottenuti prima e dopo l’intervento (un mese e dopo mediana di 3,5 anni). L’età media del campione era di 43,2 anni (range …
