Hypogravity research and educational parabolic flight activities conducted in Barcelona: a new Hub of innovation in Europe
We report on different research and educational activities related to parabolic flights conducted in Barcelona since 2008. We use a CAP10B single-engine aerobatic aircraft flying out of Sabadell Airport and operating in visual flight conditions providing up to 8 seconds of hypogravity for each parabola. Aside from biomedical experiments being conducted, different student teams have flown in parabolic flights in the framework of the international contest ‘Barcelona Zero-G Challenge’, and have published their results in relevant symposiums and scientific journals. The platform can certainly be a good testbed for a proof-of-concept before accessing other microgravity platforms, and has proved to be excellent for motivational student campaigns.Peer ReviewedPostprint (author's final draft

Anatomical and functional brain approach along short abrupt changes in G-levels
To conduct experiments under abrupt changes in g-levels, a single-engine aerobatic aircraft has been used, providing 6-8 seconds of reduced gravity, preceded and followed by 5-7 seconds of hypergravity periods. Due to the specific conditions of the flight and previous findings [1], the hypothesis of the present work lies on the idea that some sensory inputs could have a notorious effect on brain final responses when gravity is altered. Therefore, this study focuses on the evaluation of such hypothesis, based on the analysis of the evolution in time of intracranial activity of limbic, visual and auditory cortices. Five subjects (N=5, age 41¿14 years) have flown in parabolic flight with their eyes both open and closed. Electroencephalogram signals were recorded with an Emotive Epoc headset, synchronized with a triaxial accelerometer. The intracranial brain bioelectric activity (standardized current density) throughout the parabola, was calculated by applying Standard Low Resolution Brain Electromagnetic Tomography, and it was analyzed for the limbic, visual and auditory cortices. Intracranial activity of the Temporal, Parietal and Occipital lobes were carried out as well in order to compare the different periods/phases of the flight. Results detected a lower brain activity during the hypogravity phase in all lobes and cortices, only in the case of open eyes. The bioelectrical brain activity along the parabola showed similar patterns in all lobes and cortices, when visual inputs are highlighted. Suppressing the sight, two major behaviors were detected in brain activity: one for temporal lobe and auditory cortex, and second one for the rest of the lobes and visual cortex. It Seemed that, flying with closed eyes, other sensory stimuli were enhanced, in this case the auditory cortex. To confirm the validity of the results two-way ANOVA (factors lobe/phases) and Fisher post hoc test have been applied on mean intracranial activity values in all cases. Spectral entropy evolution in time has been considered as a fast indicator of the sudden extracranial brain activity variation during short g-changes. For open eyes, spectral entropy values indicated a slight decrease at the onset of the hypogravity phase, whereas in case of closed eyes, this change was detected in the last seconds of the parabola, even though these fluctuations were statistically non-significant. Results suggest that some of the sensory inputs can indeed have an impact on brain final response, when gravity conditions are altered.Peer ReviewedPostprint (published version

Microgravity effects on frozen human sperm samples
Purpose: Microgravity has severe effects on cellular and molecular structures as well as on metabolic
interactions. The aim of this study is to investigate the effects of microgravity (µg) exposure on human frozen sperm samples.
Methods: Sibling samples from 15 normozoospermic healthy donors were frozen using glycerol as
cryoprotectant and analyzed under microgravity and ground conditions. Microgravity was obtained by
parabolic flights using a CAP10B plane. The plane executed 20 parabolic maneuvers with a mean of 8.5
seconds of microgravity for each parabola.
Results: Frozen sperm samples preserved in cryostraws and stored in a secure and specific nitrogen vapor
cryoshipper do not suffer significant alterations after µg exposure. Comparing the study group (µg) and
the control group (1g), similar results were obtained in the main parameters studied: Sperm motility
(M/ml) 13.72 ± 12.57 vs 13.03±12.13 (-0.69 95% CI [-2.9;1.52]); Progressive a+b sperm motility (%)
13 21.83±11.69 vs 22.54±12.83 (0.03 95% CI [-0.08;0.15]); Sperm vitality (%) 46.42±10.81 vs 44.62±9.34
14 (-0.04 95% CI [-0.13;0.05]); Morphologically normal spermatozoa (%) 7.03±2.61 vs 8.09±3.61 (0.12
15 95% CI [0.01;0.24]); DNA sperm fragmentation by SCD (%) 13.33±5.12 vs 13.88±6.14 (0.03 95% CI [-
16 0.09;0.16]); Apoptotic spermatozoa by MACS (%) 15.47±15.04 vs 23.80±23.63 (-0.21 95% CI [-
17 0.66;1.05]).
Conclusion: The lack of differences obtained between frozen samples exposed to µg and those
maintained in ground conditions provides the possibility of considering the safe transport of human male
gametes to space. Nevertheless, further research is needed to validate the results and to consider the
possibility of creating a human sperm bank outside the Earth.Peer ReviewedPostprint (author's final draft
La regulación del derecho a la autodeterminación informativa en El Salvador
El derecho a la Autodeterminación Informativa tiene por objeto dotar a las personas de un control sobre sus datos personales a través de una serie de principios y facultades, los cuales han sido cambiantes desde el origen de este derecho, debido al desarrollo acelerado que ha sufrido la tecnología y con ella la recolección y tratamiento de datos personales, por lo que es fácil predecir que ante esta realidad el Derecho a la Autodeterminación Informativa se encuentra todavía en constante evolución. Este derecho en la doctrina y en la legislación comparada ha alcanzado un gran desarrollo, regulando temas relativos a la información de las personas en redes sociales y en buscadores de internet (derecho al olvido), además de los datos en la nube (derecho a la portabilidad), el control del procesamiento de datos personales en el extranjero, la transferencia de datos al extranjero y un ente administrativo que vela por el cumplimiento de la legislación relativa a la protección de datos. El Salvador no es ajeno a las causas que originan la necesidad de la regulación del tratamiento de datos personales, Es indiscutible además que existe desarrollo del derecho a la autodeterminación informativa, tanto a nivel jurisprudencial como legislativo, pero este es insuficiente ya que la legislación es dispersa, se encuentra restringida por su propio ámbito de aplicación y no corresponde al desarrollo tecnológico actual. Por lo antes expuesto, existe la necesidad de crear una ley que regule la protección de datos de carácter personal adaptada a las exigencias tecnológicas, incorporando las facultades y principios ya establecidos en doctrina y el derecho comparado
