Laboratory Animal Research (2020) 36:33 Laboratory Animal Research https://doi.org/10.1186/s42826-020-00066-w REVIEW Open Access Cryopreservation of mouse resources Toru Takeo1* , Satohiro Nakao1, Yoshiko Nakagawa1, Jorge M. Sztein1 and Naomi Nakagata2 Abstract The cryopreservation of sperm and embryos is useful to efficiently archive valuable resources of genetically engineered mice. Till date, more than 60,000 strains of genetically engineered mice have been archived in mouse banks worldwide. Researchers can request for the archived mouse strains for their research projects. The research infrastructure of mouse banks improves the availability of mouse resources, the productivity of research projects, and the reproducibility of animal experiments. Our research team manages the mouse bank at the Center for Animal Resources and Development in Kumamoto University and continuously develops new techniques in mouse reproductive technology to efficiently improve the system of mouse banking. In this review, we introduce the activities of mouse banks and the latest techniques used in mouse reproductive technology.

Abstract: Increasing numbers of women are undergoing oocyte or tissue cryopreservation for medical or social reasons to increase their chances of having genetic children. Social egg freezing (SEF) allows women to preserve their fertility in anticipation of age-related fertility decline and ineffective fertility treatments at older ages. The purpose of this study was to summarize recent findings focusing on the challenges of elective egg freezing. -
Effects of Sample Treatments on Genome Recovery Via Single-Cell Genomics
The ISME Journal (2014) 8, 2546–2549 & 2014 International Society for Microbial Ecology All rights reserved 1751-7362/14 www.nature.com/ismej SHORT COMMUNICATION Effects of sample treatments on genome recovery via single-cell genomics Scott Clingenpeel1, Patrick Schwientek1, Philip Hugenholtz2 and Tanja Woyke1 1DOE Joint Genome Institute, Walnut Creek, CA, USA and 2Australian Centre for Ecogenomics, School of Chemistry and Molecular Biosciences, University of Queensland, Brisbane, Queensland, Australia Single-cell genomics is a powerful tool for accessing genetic information from uncultivated microorganisms. Methods of handling samples before single-cell genomic amplification may affect the quality of the genomes obtained. Using three bacterial strains we show that, compared to cryopreservation, lower-quality single-cell genomes are recovered when the sample is preserved in ethanol or if the sample undergoes fluorescence in situ hybridization, while sample preservation in paraformaldehyde renders it completely unsuitable for sequencing. The ISME Journal (2014) 8, 2546–2549; doi:10.1038/ismej.2014.92; published online 13 June 2014 Relatively little is known about the functioning of genomes from single cells. Three methods of sample complex microbial communities, largely due to the preservation were tested: cryopreservation with difficulty in culturing most microbes (Rappe and 20% glycerol as a cryoprotectant, preservation in Giovannoni, 2003). Although metagenomics can 70% ethanol, and preservation in 4% paraformalde- provide information on the genetic capabilities of hyde. Because paraformaldehyde treatment causes the entire community, it is difficult to connect crosslinks between nucleic acids and proteins, we predicted gene functions to specific organisms using tested cells exposed to 4% paraformaldehyde with metagenomics (Morales and Holben, 2011). -
Progress in Nuclear Waste Vitrification by Ceramic Melter Technique
JP9950237 PROGRESS IN NUCLEAR WASTE VITRIFICATION BY CERAMIC MELTER TECHNIQUE S. WEISENBURGER Forschungszentrum Karlsruhe Institut fur Nukleare Entsorgungstechnik P.O.BOX 3640, 76021 Karlsruhe, Germany ABSTRACT Nuclear waste vitrification by using the liquid-fed ceramic-lined waste glass melter process started in 1973 with the pioneering development at Batelle Pacific Northwest Laboratory. The first radioactive plant applying this technique was the PAMELA plant in Mol/ Belgium which was put into hot operation in 1985. A main part of the technology for this plant including the melter was developed by the Institut fur Nukleare Entsorgungstechnik (INE) of Forschungszentrum Karlsruhe (FZK)! For the time being there is an increasing demand for the availability of small-scale vitrification units for processing of small stocks of high level liquid wastes (HLLW). Limited quantities of HLLW solutions were obtained during the period of development of reprocessing techniques at various international sites. One example is the former WAK (Wiederaufarbeitungs-anlage Karlsruhe) reprocessing plant. It is located at the site of Forschungszentrum Karlsruhe and is now under decommissioning. The overall decommissioning program includes vitrification of 70 m3 of stored HLLW with a total p7y radioactivity of 8.9 x E17 Bq. This paper focuses on progress achieved in the design of small-scale liquid-fed ceramic glass melters for these purposes. Improvements are described regarding extension of power electrode life time by optimized air cooling, glass pouring operation, off-gas pipe cleaning, glass level detection system in the melt tank, and arrangement of a small-scale melter in a hot a cell. Some test results achieved with the new melter are also outlined.
