Brick Shaped Antenna Module for Microwave Brain Imaging Systems

In this letter, we describe and validate a microwave antenna designed for an imaging device for the diagnosis and monitoring of cerebrovascular pathologies. The antenna consists of a printed monopole immersed in a parallelepipedic block of semiflexible material with custom-permittivity, which allows to avoid the use of liquid coupling media and enables a simple array arrangement. The “brick” is built with a mixture of urethane rubber and graphite powder. The -10 dB frequency band of the antenna is 800 MHz-1.2 GHz, in agreement with the device requirements. The designed brick antenna is assessed in terms of power penetration, reflection, and transmission coefficients. To show the performance of the antenna in the relevant application scenario, an experiment has been carried out on an anthropomorphic head phantom, measuring the differential signals between healthy state and hemorrhagic stroke mimicking condition for different antennas positions

Területfejlesztés vagy iparpolitika?: A francia versenyképességi pólus program tapasztalatai

A tanulmány felvázolja a területfejlesztési és a verseny-, illetve iparpolitikának a metszetében elhelyezkedő francia versenyképességi pólusok kialakulásának előzményeit, elméleti hátterét, és az alig egy évtizedes múltra visszatekintő gyakorlati tapasztalatok összegzésére vállalkozik. A versenyképességi pólusok az innovációs szereplők hálózatos kapcsolataira épülnek, fejlődésüket a szereplők közti együttműködés minősége alakítja. Miközben a teljesítmény-szemléletű politikák a legdinamikusabban fejlődő régiókra összpontosítanak az ország európai és globális pozícióját szem előtt tartva, és a pólusok esetében is a legígéretesebb csúcsipari ágazatok támogatását szorgalmazzák, a közel fél évszázados múltú egyenlősítő célzatú területfejlesztési politikák céljai a pólusok nagy számával és a hagyományos, érettebb ágazatok támogatásával realizálódnak. A kettős célkitűzés egyidejűleg a pólusprogram esetében is nehezen teljesíthető, de mindmáig jelen van az ország jövőjét meghatározó területpolitikai vitákban

Plasmonic nanoparticles and their characterization in physiological fluids

Nanoparticles possess unique properties beyond that of classical materials, and while these properties can be used for designing a dedicated functionality, they may also pose a problem to living organisms, to human health and the environment. The specific primary routes by which nanoparticles may interact with the human body include inhalation, injection, ingestion and application to the skin. Independent of the entry route, the particles inevitably encounter a complex physiological fluid populated with e.g. proteins, vitamins, lipids and salts/ions. Different consequences of such an encounter may include formation of a surface-bound protein layer, particle dissolution or aggregation, which are expected to have a crucial impact on cellular interaction. Understanding cellular responses to nanoparticle interactions starts with understanding particle behavior in physiological fluids. Nanoparticles are now available in practically any size, shape and functionalization, to promote distinct optical, magnetic, and physico-chemical properties, making the prediction of their behavior, in physiological fluids, not a trivial task. Characterization has therefore become of paramount importance. In this review, we give an overview about the diversity of physiological fluids as well as present an inventory of the most relevant experimental techniques used to study plasmonic nanoparticles

Replacement of fish oil with vegetable oil blends in feeds for greater amberjack (Seriola dumerili) juveniles: effect on growth performance, feed efficiency, tissue fatty acid composition and flesh nutritional value

[EN] This study was undertaken to assess the effects of fish oil (FO) substitution by a mixture of alternative vegetable oils (VO) on Seriola dumerili culture performance. A 154-day feeding experiment was conducted using juveniles (39.2 +/- 1.6g average weight). Three isolipidic and isoenergetic meal-based diets were formulated varying their lipid component. The control diet contained 100% FO (FO100), whereas diets VO50 and VO100 included 1/2 of oil blend and all the oil from blend of palm oil (PO) and linseed oil (LO) as substitute for FO, respectively. Dietary regime did not significantly affect growth performance, biometric indices, feed efficiency, plasma chemistry and liver and muscle lipid contents. Nonetheless, dietary VO inclusion impacted on the fatty acid profile of target tissues, especially in the liver. Fatty acid profiles of the fillets reflected those of the dietary oils except that there was apparent selective utilization of palmitic acid (C16:0) and oleic acid (C18:1n-9) and apparent selective retention of long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid (EPA, C20:5n-3) and docosahexaenoic acid (DHA, C22:6n-3). The nutritional value and the potential ability to prevent the development of coronary heart diseases of the flesh lipid fraction decreased with gradual FO substitution.Ministerio de Ciencia e Innovacion (MICINN), Grant/Award Number: AGL2011-30547-C03-02Monge-Ortiz, R.; Tomas-Vidal, A.; Rodriguez-Barreto, D.; Martínez-Llorens, S.; Perez, J.; Jover Cerda, M.; Lorenzo, A.

Situation, challenges, and SEOM recommendations for the future of undergraduate education in Oncology in Spain

Purpose The Spanish Society of Medical Oncology (SEOM, for its Spanish acronym) would like to attest to the relevance of training in Oncology as part of the undergraduate education in Medicine program and issue recommendations to improve said training, with the aim of responding better to the challenges that cancer poses to our society. Materials and methods The curricula of 42 schools of medicine were reviewed with interviews with at least one teaching medical oncologist from each faculty. The qualitative and opinion analysis was completed by means of an online questionnaire targeting lecturers, resident tutors, and residents in Medical Oncology (MO), enabling the detection of needs and areas for improvement at an organizational level and in terms of skill acquisition. Results While the number of medical schools with a specific, mandatory program in MO has grown by up to 90%, it has not been accompanied by an increase in independent programs. Instead, they largely consist of programs shared with other specialties (61% of the medical faculties). In most of the undergraduate education programs, Oncology contents are fragmented and approached from the perspective of each organ system. Conclusions Despite the positive evolution in recent years, the heterogeneity in Oncology contents during undergraduate education training continues to be remarkable. Cross-sectional programs with an integral vision, taught in the final years of undergraduate medical education would be desirable. Among the recommendations for improvement of training in Medical Oncology, the SEOM proposes that updated, theoretical content be incorporated and clinical practice in Medical Oncology departments be promotedThis study was funded as an unrestricted grant by Jansse

Influence of potato crisps processing parameters on acrylamide formation and bioaccesibility

A fractional factorial design was used to evaluate the effects of temperature, frying time, blanching treatment and the thickness of potato slices on acrylamide content in crisps. The design was used on freshly harvested and four-month stored potatoes. The critical factors found were temperature and frying time, and the interaction between blanching treatment and slice thickness. Once frying conditions were selected, an acrylamide content of 725 and 1030 mg kg−1 was found for non-stored and 4-month stored tubers, with adequate textural parameters in both cases. The difference in concentration is related to storage conditions, which must be controlled in order to control acrylamide levels. Bioaccesibility studies demonstrated that acrylamide concentration remained at 70%, and reductions took place mainly at the intestinal phase, as a result of reaction with nucleophilic compounds.This research was funded by Fritos Totis SA de CV and CONACyT-Incentives for Research, Technological Development and Innovation Program (conv 2016-232271)S
