- Biobanks are an organized collection of biological material and associated data. They are a fundamental resource for life science research and contribute to the development of pharmaceutical drugs, diagnostic markers and to a deeper understanding of the genetics that regulate the development of all life on earth. Biobanks are well established in High Income Countries (HIC) and are rapidly emerging in Low and Middle Income Countries (LMIC). Surveys among biobanks operating in a LMIC setting indicate that limited resources and short term funding tied to specific projects threaten the sustainability of the biobanks. Fit-for-purpose biobanks targeting major societal challenges such as HIV and Malaria provide an excellent basis for integrating biobanks with the available research communities in LMIC regions. But to become sustainable for the future it is important that biobanks become an integrated part of local research communities. To achieve this, the cost of operating biobanks must be lowered, templates must be developed to support local ethics committees and researchers must be given the opportunity to build experience in successfully operating biobank based research projects. The B3Africa consortium is based on these conclusions and set up to support biobank based research by creating a cost efficient Laboratory Information Management System (LIMS) for developing biobanks and also contribute to the training and capacity building in the local research community. The technical platform called the eB3Kit is open source and consists of a LIMS and a bioinformatics module based on the eBiokit that allow researchers to take control over the analysis of their own data. Along with the technical platform the consortium will also contribute training and support for the associated infrastructures necessary to regulate the ethical and legal implications of biobank based research.

- The heated 5G network deployment race has already begun with the rapid progress in standardization efforts, backed by the current market availability of 5G-enabled network equipment, ongoing 5G spectrum auctions, early launching of non-standalone 5G network services in a few countries, among others. In this paper, we study current and future wireless networks from the viewpoint of energy efficiency (EE) and sustainability to meet the planned network and service evolution toward, along, and beyond 5G, as also inspired by the findings of the EU Celtic-Plus SooGREEN Project. We highlight the opportunities seized by the project efforts to enable and enrich this green nature of the network as compared to existing technologies. In specific, we present innovative means proposed in SooGREEN to monitor and evaluate EE in 5G networks and beyond. Further solutions are presented to reduce energy consumption and carbon footprint in the different network segments. The latter spans proposed virtualized/cloud architectures, efficient polar coding for fronthauling, mobile network powering via renewable energy and smart grid integration, passive cooling, smart sleeping modes in indoor systems, among others. Finally, we shed light on the open opportunities yet to be investigated and leveraged in future developments.

Expression Analysis of Proline Rich 15 (Prr15) in Mouse and Human Gastrointestinal Tumors

- Proline rich 15 (Prr15), which encodes a protein of unknown function, is expressed almost exclusively in postmitotic cells both during fetal development and in adult tissues, such as the intestinal epithelium and the testis. To determine if this specific expression is lost in intestinal neoplasias, we examined Prr15 expression by in situ hybridization (ISH) on mouse intestinal tumors caused by different gene mutations, and on human colorectal cancer (CRC) samples. Prr15/PRR15 expression was consistently observed in mouse gastrointestinal (GI) tumors caused by mutations in the Apc gene, as well as in several advanced stage human CRCs. In contrast, no Prr15 expression was detected in intestinal tumors derived from mice carrying mutations in the Smad3, Smad4, or Cdkn1b genes. These findings, combined with the fact that a majority of sporadic human CRCs carry APC mutations, strongly suggest that the expression of Prr15/PRR15 in mouse and human GI tumors is linked, directly or indirectly, to the absence of the APC protein or, more generally, to the disruption of the Wnt signaling pathway.
