Antibacterial PEGylated Solid Lipid Microparticles for Cosmeceutical Purpose: Formulation, Characterization, and Efficacy Evaluation
2020
The development of efficacious means of delivering antioxidant polyphenols from natural sources for the treatment of skin diseases is of great interest for many cosmetic and pharmaceutical companies. Resveratrol (RSV) and Limonene (LIM) have been shown to possess good anti-inflammatory and antibacterial properties against Staphylococcus aureus infections responsible for many skin disorders, such as acne vulgaris. In this study, solid lipid microparticles are designed as composite vehicles capable of encapsulating a high amount of trans-RSV and enhancing its absorption through the stratum corneum. A microparticulate system based on mixture of PEGylate lipids, long-chain alcohols and LIM is a…
Predicting Outcome of Aortic Dissection with Patent False Lumen by Computational Flow Analysis
2014
Although Type B aortic dissection (AoD) has better in-hospital survival than Type A AoD, the short- and long term outcome for patients remains challenging, with 50–80% deaths at 5-years. Dissection-related complications include rapid aortic expansion, impending rupture, and malperfusion syndromes. We aimed to assess hemodynamic implications of patients with patent false lumen (FL) of dissected aorta. Computational fluid dynamic analyses were performed on patient-specific aortic geometries reconstructed from computed tomography scans of 25 patients with AoDs, who were admitted in our hospital from 2007 to 2013. We used the development of acute complications and chronic aneurysmal evolution a…
Does the Sun Shine byppor CNO Fusion Reactions?
2002
We show that solar neutrino experiments set an upper limit of 7.8% (7.3% including the recent KamLAND measurements) to the fraction of energy that the Sun produces via the CNO fusion cycle, which is an order of magnitude improvement upon the previous limit. New experiments are required to detect CNO neutrinos corresponding to the 1.5% of the solar luminosity that the standard solar model predicts is generated by the CNO cycle.
Desenvolupament i validació d'una metodologia per a l'avaluació de la cultura de seguretat per mitjà de l'observació de reunions de treball en una ce…
2010
L'objectiu d'aquest treball és descriure el desenvolupament i la validació d'una metodologia per a avaluar la cultura de seguretat per mitjà de l'observació de reunions de treball. Es va partir de la definició de cultura de seguretat més estesa dins el sector (International Atomic Energy Agency, 1991), les cinc dimensions que presenta i els atributs corresponents. La validesa d'aquesta metodologia es posà a prova en una central nuclear mitjançant l'observació d'un total de 36 reunions de treball de naturalesa molt diversa. Els resultats indiquen que l'observació de les reunions és un mètode útil per a l'avaluació de la cultura de seguretat. Comparada amb els mètodes tradicionals per a fer a…

Pasaku izmantošanas iespējas 4 - 5 gadus vecu bērnu uzvedības uzlabošanai
2017
Diplomdarba “Pasaku izmantošanas iespējas 4 – 5 gadus vecu bērnu uzvedības uzlabošanai” mērķis ir izpētīt pasaku izmantošanas iespējas 4 – 5 gadus vecu bērnu uzvedības problēmu mazināšanā. Darba teorētiskā daļa satur informāciju par pētījuma problemātiku, empīriskā daļa atspoguļo sākotnējo uzvedības problēmu biežumu grupā X un pasaku ietekmi uz bērniem, atklājot pasaku izmantošanas iespējas. Pētījuma uzdevumi ir: analizēt teorētisko literatūru par pētījuma problemātiku; analizēt bērnu literatūru un radīt pasakas, kas atstātu pozitīvu iespaidu uz bērnu uzvedību; veikt empīrisku pētījumu par pasaku izmantošanas iespējām 4 – 5 gadus vecu bērnu uzvedības problēmu mazināšanā. Izvirzītā hipotēze …
Mathematical problem-solving in early school years with Bee-bot
2018
Los entornos relacionados con la robótica y los lenguajes visuales de programación por bloques permiten plantear tareas que pueden ser entendidas como problemas con contenido matemático aptos para edades escolares tempranas. Estos entornos permiten proponer situaciones problemáticas en edades en las que el formalismo o el escaso conocimiento matemático impide a los estudiantes abordar problemas matemáticos más complejos. En este trabajo se da cuenta de cómo el robot programable Bee-bot constituye un dispositivo privilegiado donde poder observar cómo los estudiantes toman decisiones durante el proceso de resolución. The environments related to robotics and the visual block-based programming …
Diagnostic efficacy of panoramic mandibular index to identify postmenopausal women with low bone mineral densities
2011
Objectives: The aim of the study was to compare and assess the accuracy of panoramic mandibular index (PMI) and antegonial index (AI) in the panoramic radiographs of postmenopausal women with normal and low skeletal bone mineral densities( BMD) diagnosed by using dual energy x-ray absorptiometry ( DXA). Study Design: In panoramic radiographs obtained from 40 post menopausal women( 20 normal and 20 osteoporo tic) aged between 50-75 who’s BMD has already been assessed by a DXA, the mean was calculated for PMI and AI index values measured in the right and left mandibles. The PMI and AI index values were evaluated using the student’s t test. The correlation between the observers for indices was…
Void Zone: Readings of Fear and Solitude in the Post-industrial/Post-modern City
2009
The explosion of the city consequent to the industrial revolution and, even more, the sprawling diffusion arising in Europe from the post-industrial transformations let us talk about the disappearing of the border of the city. A diffuse urbanization cancer wastes the landscape and finally the city can be defined more for what it's not (it's no country, it's no natural landscape, it's no nature) than for a definite urban space. If the city is configured principally by its surplus (interstices, spaces under, undefined extensions of un-urban urbanization, infrastructural nets...), in a different sense we may, finally, talk about the thickening of the border of the contemporary, postmodern, Eur…
Changes in meibomian fatty acids and ocular surface in patients with meibomian gland dysfunction after minocycline treatment
2008
International audience; Purpose:Tear film lipid layer (TFLL) is a very structured layer with essential functions. Its structure is highly dependent on chemical and physical characteristics of lipids composing the TFLL We previously published alterations in the composition of TFLL in patients suffering from meibomian gland dysfunction (MGD). Branched chain fatty acids (BCFA) were significantly increased, suggesting that BCFA may be associated with the disease. The aim of this study was to evaluate the effect of a treatment by oral minocycline associated to lid hygiene versus lid hygiene only on changes in ocular surface abnormalities and in meibomian fatty acid composition in patients suffer…
