Predictability of short implants ( < 10 mm) as a treatment option for the rehabilitation of atrophic maxillae: a systematic review
2016
Background Short implants (< 10 mm) are one of the treatment options available in cases of limited vertical bone. A purpose of this paper is to evaluate the predictability of short implants as an alternative to technically molthough such implants are now widely used, there is controversy regarding their clinical reliability. There complex treatments in patients with atrophic maxillae, based on a systematic review of the literature and the analysis of the implant survival rates, changes in peri-implant bone level, and associated complications. It is postulated that short implants offer clinical results similar to those of longer implants. Material and Methods A Medline-PubMed search was made…
Delivery of siHIF‐1α to Reconstruct Tumor Normoxic Microenvironment for Effective Chemotherapeutic and Photodynamic Anticancer Treatments
2021
The tumor hypoxic microenvironment not only induces genetic and epigenetic changes in tumor cells, immature vessels formation for oxygen demand, but also compromises the efficiency of therapeutic interventions. On the other hand, conventional therapeutic approaches which kill tumor cells or destroy tumor blood vessels to block nutrition and oxygen supply usually facilitate even harsher microenvironment. Thus, simultaneously relieving the strained response of tumor cells and blood vessels represents a promising strategy to reverse the adverse tumor hypoxic microenvironment. In the present study, an integrated amphiphilic system (RSCD) is designed based on Angiotensin II receptor blocker cand…
Reproducibility and validity of a food frequency questionnaire among pregnant women in a Mediterranean area
2013
Background: Studies exploring the role of diet during pregnancy are still scarce, in part due to the complexity of measuring diet and to the lack of valid instruments. The aim of this study was to examine the reproducibility and validity (against biochemical biomarkers) of a semi-quantitative food frequency questionnaire (FFQ) in pregnant women. Methods: Participants were 740 pregnant women from a population-based birth cohort study in Valencia (INMA Study). We compared nutrient and food intakes from FFQs estimated for two periods of pregnancy (reproducibility), and compared energy-adjusted intake of several carotenoids, folate, vitamin B12, vitamin C and a-tocopherol of the FFQ in the firs…
Perfluoroalkylated amphiphilic MUC1 glycopeptide antigens as tools for cancer immunotherapy.

The synthesis of perfluoroalkylated glycopeptide antigens and their specific binding to anti-MUC1 mouse antibodies is reported.
Bacteriophage Adherence to Mucus Mediates Preventive Protection against Pathogenic Bacteria
2019
The mucosal surfaces of animals are habitat for microbes, including viruses. Bacteriophages—viruses that infect bacteria—were shown to be able to bind to mucus. This may result in a symbiotic relationship in which phages find bacterial hosts to infect, protecting the mucus-producing animal from bacterial infections in the process. Here, we studied phage binding on mucus and the effect of mucin on phage-bacterium interactions. The significance of our research is in showing that phage adhesion to mucus results in preventive protection against bacterial infections, which will serve as basis for the development of prophylactic phage therapy approaches. Besides, we also reveal that exposure to m…
La Justicia Medioambiental y su posible introducción en el Ordenamiento Jurídico Español
2014
La tesis se centra en el concepto de la Justicia Medioambiental, entendida como “el trato justo y la participación significativa de todas las personas, sin consideración de raza, color, origen nacional o posición económica, en el desarrollo, implementación y cumplimiento de las leyes, reglamentaciones y políticas medioambientales”. La tesis analiza el surgimiento del movimiento de la Justicia medioambiental en los Estados Unidos en la década de los ochenta del siglo XX, y realiza un recorrido histórico por las fases de consolidación y de posterior expansión del mismo en suelo europeo. Describe el marco de la justicia medioambiental, entendido como un modelo de análisis de los conflictos med…
Tensiones constitucionales de la intervención del estado colombiano en la exploración y explotación minera respecto de las personas y el territorio
2022
Dentro del marco de la presente investigación, se direcciona estudiar las existentes e históricas tensiones constitucionales entre las entidades territoriales y las facultades propias de su autonomía, así como el poder central materializado a través de la nación, en tal sentido estudiar las figuras conexas, los principios, las regulaciones, la normativa y la jurisprudencia. Lo anterior, a partir de un estudio hermenéutico desde los enfoques del iuspositivismo vs. Iusnaturalismo, los cuales ejercen una función orientadora en las vías y resoluciones jurídicas, frente a las tensiones en cuestión. Por su parte, el modelo de la organización territorial y administrativa del Estado colombiano resp…

Valutare il merito. Pistis ed epiekeia nella Retorica di Aristotele.
2017
Nel secondo capitolo del primo libro della Retorica, definendo la prova basata sull’ethos (1356a 4-13), Aristotele collega la capacità dell’oratore di risultare credibile (pistos) presso il suo uditorio all’epieikeia, una qualità morale tipica del saggio (phronimos) che svolge un ruolo importante anche nella teoria aristotelica della giustizia (EN 1337a 32-1138a 3). In linea generale, la caratteristica specifica dell’epieikes è per Aristotele la capacità di esprimere giudizi e prendere decisioni caso per caso tenendo conto delle circostanze, anche al di là di ciò che è stabilito dalla legge (dikaion). In questo articolo mettiamo in luce come questo riferimento all’epieikeia in ambito retori…
Increased sulfate availability in saline water promotes hydrogen sulfide production in fish organic waste
2020
The risk of hydrogen sulfide (H2S) production can be a challenge in marine land-based recirculating aquaculture systems (RAS). Hydrogen sulfide is a toxic gas that can cause massive fish mortality even at low concentrations, and in addition, serious odour problems in the surroundings. It is a bacterial by-product originating from the degradation of organic matter in sulfur-rich waters such as marine waters. In order to hinder H2S production in marine land-based RAS, more information on the H2S production conditions and the associated microbiology is needed. In this study, the production of H2S from rainbow trout (Oncorhynchus mykiss) organic waste was examined using a novel H2S measurement …
