available in the repository: https://osf.io/5scb7/?view_only=de34082b5aaf460fb79a14b701e403e1Electronic devices such as smartphones have become a primary part of young people's lives. Fear of missing out seems to influence
the ability to set boundaries around sleep time. This study aims to explore (1) the use of electronic media devices in presleep
time, quality of sleep, anxiety, and well-being in females and males’ university students in the UK and Spain, (2) whether
university students’ fear of missing out (FoMO) is associated with a higher usage of electronic devices at night-time by gender.
A cross-sectional, quantitative design through Qualtrics.com was used. Samples were formed by N = 159 British participants,
and N = 172 Spanish. Findings from this study suggest that fear of missing out in females is a predictor, in both countries, of
electronic devices usage at night-time but not in males. Night-time usage of electronic devices is a predictor of: higher sleep
difficulties in British males and females and in Spanish females, higher FoMO in females from both countries but not in males,
and higher negative experiences in Spanish females. Night-time usage of electronic devices did not predict satisfaction with
life or loneliness. There is a lack in the literature examining general electronic devices usage habits during night-time, fear of
missing out, well-being and mental health, a lack of cross-cultural studies and that consider well-being not with positive or
negative factors but from a broad perspective of the construct. Findings suggest the necessity to evaluate students’ levels of
FoMO in clinical practice, especially in females, and to incorporate this construct in prevention and intervention programs

One-pot synthesis of compact DNA silica particles for gene delivery and extraordinary DNA preservation
Repairing genetic defects using exogenous DNA is a major challenge the science is currently facing. This requires the design of vectors that can effectively encapsulate, protect and target nucleic acids to specific cells safely and precisely. Here we have designed silica-based physiologically responsive particles to encapsulate, store, and transfer DNA. Unlike existing vectors (e.g., viral or lipidic particles), these DNA@SiO2 systems are very stable at room temperature. We also demonstrate how they protect the encapsulated DNA from exposure to different biological and physicochemical stresses, including DNase, denaturation temperatures (>100 °C), or reactive oxygen species (ROS). Remarkably, upon cellular uptake, these vectors dissolve safely unpacking the DNA and transfecting the cells.Acknowledgments: We are grateful to D.

Tailoring physicochemical properties of collagen-based composites with ionic liquids and wool for advanced applications
Wool, choline dihydrogen phosphate ([Ch][DHP]) or choline serinate ([Ch][Seri) ionic liquids (ILs) were incorporated into native collagen formulations and films were prepared by compression molding. Scanning electron microscopy (SEM) images showed no agglomeration, indicating good dispersion of additives within films. The denaturation peak observed by differential scanning calorimetry (DSC), along with infrared spectroscopy (FTIR) results, showed that collagen fibrillary structure was preserved in all samples. These outcomes were correlated with X-ray diffraction (XRD) patterns. Wool or ILs addition increased tensile strength and improved electrical conductivity and all films showed antistatic behaviour. The samples showed a high dielectric constant, mainly determined by mobile charge contributions. This work shows the potential of native collagen films with tuneable physical-chemical characteristics for a new generation of sustainable materials for a wide variety of applications.This research was funded by MCI/AEI/FEDER, UE, grant number RTI2018-097100-B-C22.

Sustainable Collagen Composites with Graphene Oxide for Bending Resistive Sensing
This work reports on the development of collagen films with graphene oxide nanoparticles (GO NPs), aiming toward the development of a new generation of functional sustainable sensors. For this purpose, different GO NP contents up to 3 wt % were incorporated into a collagen matrix, and morphological, thermal, mechanical and electrical properties were evaluated. Independently of the GO NP content, all films display an increase in thermal stability as a result of the increase in the structural order of collagen, as revealed by XRD analysis. Further, the inclusion of GO NPs into collagen promotes an increase in the intensity of oxygen characteristic absorption bands in FTIR spectra, due to the abundant oxygen-containing functional groups, which lead to an increase in the hydrophilic character of the surface. GO NPs also influence the mechanical properties of the composites, increasing the tensile strength from 33.2 ± 2.4 MPa (collagen) to 44.1 ± 1.0 MPa (collagen with 3 wt % GO NPs). Finally, the electrical conductivity also increases slightly with GO NP content, allowing the development of resistive bending sensors.This research was funded by Grant PID2021-124294OB-C22 funded by MCI/AEI10.13039/501100011033 and by “ERDF A way of making Europe”.

GENERAL ASPECTS REGARDING THE GROWTH FRESHWATER FISH IN CUBES, AN ALTERNATIVE FOR AQUACULTURE IN ROMANIA
Due to the increased consumption of fish, as an alternative to achieving healthy population nutrition, the development of European aquaculture also shows an increasing trend. At present, freshwater culture is about 42% of total European fish production. Valuable species, from an economic point of view, can be reared in intensive systems in cages on running waters or ponds, combined with less valuable species. There are also new species that are gradually becoming increasingly important for the fish industry in Europe. Freshwater aquaculture in Romania is based on rainbow trout and carp which are still predominant species, but there is significant demand for valuable fish species [11,12,16]. Â
Magnetically responsive chitosan-pectin films incorporating Fe3O4 nanoparticles with enhanced antimicrobial activity.
Chitosan-pectin films with iron oxide (Fe3O4) magnetic nanoparticles were prepared by solution casting in order to produce biopolymer based magnetically active materials. Infrared (FTIR) spectra indicated physical interactions between the matrix and nanoparticles, corroborated by differential scanning calorimetry (DSC) results. In addition, thermal characterization suggested that the interactions between chitosan, pectin and the nanoparticles resulted in a less compact structure, influencing the film mechanical properties. Regarding vibrating-sample magnetometry (VSM) and electrical analysis, chitosan-pectin films with Fe3O4 nanoparticles showed ferrimagnetic behavior, with an increase of the dielectric constant as the nanoparticle concentration increased. Furthermore, films displayed enhanced antimicrobial activity against Escherichia coli (Gram-negative) and Staphylococcus epidermidis (Gram-positive) bacteria. Therefore, chitosan-pectin films with Fe3O4 magnetic nanoparticles provide promising results for active and intelligent food packaging applications.Grant PID2021-124294OB-C22 funded by MCI/AEI10.13039/501100011033 and by “ERDF A way of making Europe”.

Loot box purchases and their relationship with internet gaming disorder and online gambling disorder in adolescents: A prospective study
In recent years, the video game industry has introduced Loot Box (LB), a new type of microtransaction in which a gamer uses real currency to purchase a random virtual item within a video game. Recently, LBs became more widespread and there is evidence suggesting their similarity to online gambling. Although some studies have investigated the association between LBs with disordered gaming and disordered gambling, very few have done so with clinical indicators of these problems. Furthermore, to the best of our knowledge no longitudinal evidence of such relationships currently exists in the literature. Therefore, the present study aimed to 1) ascertain the stability of LB purchasing in minors and 2) investigate the associations between LB purchasing with gambling online and online gambling disorder within six months. A prospective cohort study was conducted at two time points six months apart. In total, 2.213 Spanish adolescents (1.067 [48.9%] boys) aged between 11 and 17 years participated in both waves. The purchase of LBs was prevalent and stable in the sample across the six months. While a positive relationship was found between purchasing LBs and online gambling six months later, the relationships between purchasing LBs and the presentation of online gambling disorder and gaming disorder require further study
