Biochips for cell biology by combined dip-pen nanolithography and DNA-directed protein immobilization.
2013
A general methodology for patterning of multiple protein ligands with lateral dimensions below those of single cells is described. It employs dip pen nanolithography (DPN) patterning of DNA oligonucleotides which are then used as capture strands for DNA-directed immobilization (DDI) of oligonucleotide-tagged proteins. This study reports the development and optimization of PEG-based liquid ink, used as carrier for the immobilization of alkylamino-labeled DNA oligomers on chemically activated glass surfaces. The resulting DNA arrays have typical spot sizes of 4-5 μm with a pitch of 12 μm micrometer. It is demonstrated that the arrays can be further functionalized with covalent DNA-streptavidi…
Semiconductor @ sensitizer composites for enhanced photoinduced processes
2021
Abstract This Chapter provides an overview of common procedures used for the preparation, characterization, and exploration of photocatalytic properties of composite materials based on inorganic semiconductors in combination with sensitizers, such as porphyrins, phthalocyanines, and related macrocyclic compounds as promoters of photoinduced processes. In this context the advantage of hybrid photocatalysts, obtained by impregnation of photosensitizers onto the surface of different semiconductors, designed for improving a choice of diverse reactions has been demonstrated, highlighting innovative aspects that contribute to better sustainability of the photocatalytic processes. Mechanistic deta…
Hydrodynamic ultrasonic maxillary sinus lift : review of a new technique and presentation of a clinical case
2010
Objectives: Placing implants in the posterior maxillary area has the drawback of working with scarce, poor quality bone in a significant percentage of cases. Numerous advanced surgical techniques have been developed to overcome the difficulties associated with these limitations. Subsequent to reports on the elevation of the maxillary sinus through the lateral approach, there were reports on the use of the crestal approach, which is less aggressive but requires a minimal amount of bone. Furthermore, it is more sensitive to operator technique, as the integrity of the sinus membrane is checked indirectly. The aim of this paper is to review the technical literature on minimally invasive sinus l…
¿Por qué la literatura?

In poetry, as well as in a good part of prose works, the rhythm of words is the music that governs reason and emotion. Literature occupies an important place in my creation. In this article I describe the different procedures in which I configure its presence in my music and the main themes in four of my works: Envoi, Como el viento, Maya and Transmutación.
Towards the integration and development of a cross-European research netwerk and infrastructure : the DEterminants of Diet and Physical ACtivity (DED…
2014
To address major societal challenges and enhance cooperation in research across Europe, the European Commission has initiated and facilitated ‘joint programming’. Joint programming is a process by which Member States engage in defining, developing and implementing a common strategic research agenda, based on a shared vision of how to address major societal challenges that no Member State is capable of resolving independently. Setting up a Joint Programming Initiative (JPI) should also contribute to avoiding unnecessary overlap and repetition of research, and enable and enhance the development and use of standardised research methods, procedures and data management. The Determinants of Diet …
A Patient Registry to Improve Patient Safety: Recording General Neurosurgery Complications
2016
Background To improve the transparency of the local health care system, treatment cost was recently referenced to disease related groups. Treatment quality must be legally documented in a patient registry, in particular for the highly specialized treatments provided by neurosurgery departments. Methods In 2013 we have installed a patient registry focused on cranial neurosurgery. Surgeries are characterized by indication, treatment, location and other specific neurosurgical parameters. Preoperative state and postoperative outcome are recorded prospectively using neurological and sociological scales. Complications are graded by their severity in a therapy-oriented complication score system (C…
Analysis of the conflicts of interest disclosed by the program reviewers of the scoliosis research society (SRS) congresses, 2010-2014.
2018
Background Conflicts of interest (COI) between industry and surgeons frequently introduce biases into surgical research. The abstracts submitted for presentation in scientific congresses are usually vetted for any indication of commercial bias. Members of review program committees regularly have recognized qualifications, and therefore certain COI are unavoidable. This study aims to determine the prevalence and magnitude of possible COI among those responsible for the selection of presentations at two important international conferences on spine surgery during a five-year period. Methodology COI declarations by those responsible for the final programs of the annual SRS (Scoliosis Research S…
Transvestibular Urethrolysis.
2011
Bladder outlet obstruction with obstructive and irritative urinary symptoms may be a complication of surgery for female urinary incontinence. In presence of persistent symptoms the therapy is surgical and usually consists in an accurate urethrolysis. The way of approach is generally transvaginal. In this paper we propose and describe our experience with a transvestibular approach.From 1995 to 2009 18 women who had undergone anti-incontinence surgery (TVT 12 pts, TOT 3 pts, Burch retropubic colposuspension 3 pts) with obstruction and/or irritative symptoms underwent to a transvestibular urethrolysys. Five patients had urinary retention the other patients had post voiding residual urine100 ml…
Expertise and Skill in Minimally Invasive Surgery
2009
New attitudes to medical ethics and demands for efficiency have brought increased attention to surgical skills and training. It is important to characterize the expertise and skill involved in the multidimensional surgical profession. At a time of change, there is a need to discuss the nature of surgical expertise, and also the prospects for resident training, with special reference to new minimally invasive techniques (MIS). In this paper, we selectively review knowledge on surgical expertise and the specific demands placed on a skilled MIS surgeon. In addition, the review contains a selection of studies from those areas that have been seen as important for the future of training in surge…
Anatomía descriptiva y funcional del ligamento cruzado anterior: implicaciones clínico-quirúrgicas
1992
El ligamento cruzado anterior (LCA) es una estructura anatómica vital para la estabilidad de la rodilla y su correcta plastias exige que su tensión, dirección y punto ble al LCA original. Este trabajo intenta actualizar los aspectos anatómicos y funcionales fundamentales para una correcta cirugía de las lesiones del LCA. The anterior cruciate ligament (ACL) is a vital structure for stability of the knee and its correct biomechanics. ACL repair by means of grafts requires that tension, direction and attachment points resemble those of original ligament. This work attempts to update the fundamental functional and anatomical aspects for correct surgery of ACL.
