Robust Differentiable Functionals in the Additive Hazards Model
(Scientific Research Publishing, 2015-10)
In this article we present a new family of estimators for the regression parameter β in the Additive Hazards Model which represents a gain in robustness not only against outliers but also against unspecific contamination ...
Novel aspects of parenchymal–mesenchymal interactions: from cell types to molecules and beyond
(Wiley, 2013-06)
Mesenchymal stem or stromal cells (MSCs) were initially isolated from the bone marrow and received their name on the basis of their ability to differentiate into multiple lineages such as bone, cartilage, fat and muscle. ...
Inflammation and oxidative stress in retinal diseases: the role of intracellular signaling in the retinal pigment epithelium
(ClinMed International Library, 2015-08)
The retinal pigment epithelium (RPE) is essential for the integrity and function of the retina. RPE cells exert key functions to maintain photoreceptors´ (PRs) viability and functionality, such as light absorption and ...
Lutein and Zeaxanthin Protect Photoreceptors from Apoptosis Induced by Oxidative Stress: Relation with Docosahexaenoic Acid
(Association for Research in Vision and Ophthalmology, 2007-11)
Purpose: Oxidative stress has been proposed as a major pathogenic factor in age-related macular degeneration (AMD), the leading cause of vision loss among elderly people of western European ancestry. Lutein (LUT) and ...
Norfloxacin treatment on E. coli in the urinary tract of mice: Effect of probiotic Lactobacilli
(Medwell online, 2006-12)
This study was perfomed to evaluate the effect of the treatment of norfloxacin, as an antimicrobial agent, on the uropathogenic Escherichia coli colonization in mice, complemented by Lactobacilli as probiotics. Norfloxacin ...
Failure and integrity analysis of casings used for oil well drilling
(Pergamon-Elsevier Science Ltd, 2017-05)
Drilling with casing (DwC) is an innovative method particularly widespread in deep shale plays, that reduces the time and cost of drilling stages. However, casings are not designed for this purpose, and still the pipes and ...
QM/MM Molecular Dynamics Study of the Galactopyranose → Galactofuranose Reaction Catalysed by Trypanosoma cruzi UDP-Galactopyranose Mutase
(Public Library of Science, 2014-10)
The enzyme UDP-Galactopyranose Mutase (UGM) catalyses the conversion of galactopyranose into galactofuranose. It is known to be critical for the survival and proliferation of several pathogenic agents, both prokaryotic and ...
Reproductive performance and weaning success in fur-chewing chinchillas (Chinchilla lanigera)
(Inst Animal Reproduction Food Research, 2014-09)
In captive chinchillas, one of the most challenging behavioral problems is the development of a stress-related abnormal repetitive behavior (ARB) known as ‘‘fur-chewing’’. We investigated whether there is a relationship ...
Sublethal Effect of Pyriproxyfen Released From a Fumigant Formulation on Fecundity, Fertility, and Ovicidal Action in Aedes aegypti (Diptera: Culicidae)
(Entomological Society of America, 2014-04)
Dengue and dengue hemorrhagic fever are mosquito-borne viral diseases that coincide with the distribution of Aedes aegypti (L.), the primary vector in the tropical and semitropical world. With no available vaccine, ...
Dual role of immune cells in the testis: protective or pathogenic for germ cells?
(Taylor & Francis, 2013-01)
The purpose of this review is to describe how the immune cells present in the testis interact with the germinal epithelium contributing to survival or apoptosis of germ cells (GCs). Physiologically, the immunosuppressor ...
