Testis Tissue

Ectopic implantation of donor testis cell aggregates in recipient mice results in de novo formation or regeneration of testis tissue and, as such, provides a unique invivo model for the study of testis development. However, currently the results are inconsistent and the efficiency of the model remains low. This study was designed to: (1) examine several factors that can potentially improve the consistency and efficiency of this model and (2) explore the use of ultrasound biomicroscopy (UBM) for the non-invasive invivo evaluation of implants. Testis cell aggregates, containing ~40% gonocytes, from 1-week-old donor piglets were implanted under the back skin of immunodeficient mice through skin incisions using gel matrices or through subcutaneous injection without using gel matrices. The addition of gel matrices led to inconsistent tissue development; gelatin had the greatest development, followed by collagen, whereas agarose resulted in poor development. The results also depended on the implanted cell numbers since implants with 100×106 cells were larger than those with 50×106 cells. The injection approach for cell implantation was less invasive and resulted in more consistent and efficient testis tissue development. UBM provided promising results as a means of non-invasive monitoring of implants.

Invasive Measurement

The development of biofilms and the related changes in porous media in the subsurface cannot be directly observed and evaluated. The primary reason that the mechanism of biofilm clogging in porous media cannot be clearly demonstrated is due to the opacity and structural complexity of three-dimensional pore space. Interest in exploring methods to overcome this limitation has been increasing. In the first part of this review, we introduce the underlying characteristics of biofilm in porous media. Then, we summarize two approaches, non-invasive measurement methods and mathematical simulation strategies, for studying fluid–biofilm–porous medium interaction with spatiotemporal resolution. We also discuss the advantages and limitations of these approaches. Lastly, we provide a perspective on opportunities for in situ monitoring at the field site.

The Mediterranean Basin

Rock art of the Mediterranean Basin of the Iberian Peninsula was declared World Heritage Site by UNESCO, it has an outstanding cultural value hence its dissemination is essential. Over the years, rock art paintings have been deteriorated and even some have disappeared. Consequently, it is quite difficult to recognise them in situ without experts. At this point, non-invasive and novel techniques can offer great potential, on the one hand, avoiding direct contact with the surface promoting its conservation, and on the other hand, through dissemination and analysis of these elements. One of the most promising techniques is Augmented Reality (AR). By means of AR applications, the visitor can see any kind of virtual content related to cultural heritage, through its mobile or tablet screen. Thus, any virtual content that is considered of interest can be added, offering in this way additional information that complements the real element. In this study, two approaches are presented for the rock art dissemination of the Cova dels Cavalls. The first is based on a marker recognition, which launches the application that displays an image of the motif and a descriptive text about it. In the second proposal, the camera device recognises the real image of the painting and the virtual information is overlapped. The study aims at evaluating the use of these AR techniques applied to rock art dissemination and shows the methodology for its development.http://dx.doi.org/10.4995/CIGeo2017.2017.6598

Glass Foam

Septal cartilage is widely used for the repair of soft tissue defects in the head, neck and nose. Tissue Engineering techniques are being investigated to create cartilage in vitro by seeding appropriate cells on resorbable scaffolds. In this study, human chondrocytes were cultured on macroporous bioactive glass foam scaffolds. The aim was to investigate how Raman spectroscopy could be used as a non-invasive technique to monitor the response of chondrocytes to a 3D scaffold in real time. The spectra were compared to scanning electron microscope (SEM) micrographs and immunohistochemistry results.
