With the ethical, legal, and societal issues (ELSI) Knowledge Base, we introduce a key element of the Biobanking and Biomolecular Resources Research Infrastructure-European Research Infrastructure Consortium (BBMRI-ERIC) Common Service ELSI, which provides ethical, legal, and societal support for researchers and biobankers involved in transnational research. In contrast to the customized support provided by the ELSI Helpdesk, the ELSI Knowledge Base will be available to the user on a self-serve basis. The information that is made available through a knowledge base comes from multiple sources, usually from several expert contributors who are well versed in the subject matter...

The work described here aimed to verify the efficiency of different extenders for cryopreservation of equine semen using sperm motility and acrosin activity as spermatic parameters. The semen was fractioned into two equal parts and resuspended in an 11% lactose solution in a 1:1 proportion, where it remained for 20 minutes at room temperature. The semen was centrifuged at 600 g for 10 minutes, and after the second centrifugation, each pellet received the freezing extender (Merck or Zorlesco) and was loaded into 4 mL straws...

Currently the most popular mouse sperm freezing medium is R18SM3+MTG containing 18% raffinose, 3% skim milk, and 0.5 mM monothioglycerol (MTG), but there is no information available about whether MTG and other antioxidants can cryoprotect mouse sperm DNA integrity. It is also uncertain if sucrose can be used successfully for sperm cryopreservation. In this report we compared the cryoprotective effects of sucrose and raffinose, as well as the antioxidants MTG, reduced glutathione (GSH), and quercetin on sperm motility, DNA integrity, and fertility in the C57BL/6J mouse strain...

AIMS: The use of primary hepatocytes in pharmacological and toxicological research as well as for clinical and biotechnological applications requires adequate storage options for these cells. However, hepatocytes are very susceptible to cryopreservation injury. Based on experience in hypothermic storage of hepatocytes, we, in this study, aimed to optimize hepatocyte cryopreservation. MATERIALS AND METHODS: Rat hepatocytes were cryopreserved in serum-containing cell culture medium or in serum-free solutions optimized for hypothermic storage, all with 10% dimethyl sulfoxide, using a standard protocol (-1°C/min in a controlled-rate freezer)...

BACKGROUND: Cold ischemia protects organs and tissues by slowing their metabolism, but it also causes ischemic injury. Minimizing cold ischemia has been an important goal in parathyroid auto- and allotransplantation, as well as the transplantation of other major organs. Parathyroid glands are responsible for calcium homeostasis by releasing parathormone (PTH) into the blood circulation. Functionality of a new parathyroid transport solution (NPTS) and effects on cell viability, PTH secretion, and calcium-sensing receptor (CaSR) levels during cold ischemia were evaluated...

Cryopreservation represents one if not the only long-term option for tissue and perhaps future organ banking. In one particular approach, cryopreservation is achieved by completely avoiding ice formation (or crystallization) through a process called vitrification. This "ice-free" approach to tissue banking requires a combination of high-concentration cryoprotective additives such as M22 (9.4 M), VS55 (8.4 M), or DP6 (6 M) and sufficiently fast rates of cooling and warming to avoid crystallization...

AIM: The present study evaluates the effect of different concentrations of antioxidants (catalase - CAT and alpha lipoic acid - ALA) on the follicular activation and morphology, DNA damage, ROS production, and mitochondrial activity in vitrified sheep ovarian tissue. METHODS: This experiment was divided into two steps. First, ovarian fragments were distributed into the following treatments: fresh tissue or control (CTR), incubation (INC), vitrification without antioxidant (VWA), with CAT (10, 20, or 40 IU mL-1 ) or ALA (25, 50, or 100 μM mL-1 )...

OBJECTIVES: We have explored a better method to preserve and store human medically amputated large size samples. The approach involved developing a special embalming solution and procedures for biopreservation and biostorage of a large-sized sample as a whole specimen rather than dissected small parts. Evaluation of the effect of our special embalming solution and procedures on whole human amputated extremities compared with excised small tissues was conducted. Histological and morphological techniques and elemental analyses were utilized to assess the effects of our new method using the special embalming solution...

Biobanking and BioMolecular resources Research Infrastructure (BBMRI)- European Research Infrastructure Consortium (ERIC) is the largest infrastructure launched in Europe in health research. By nature it is a distributed infrastructure, in which biological samples and data are hosted by the European Member States biobanks. As of today, BBMRI-ERIC consists of 19 European Member States and 1 international organization, the International Agency for Research on Cancer. This means that BBMRI-ERIC has a population of >500 million individuals in Europe...

Most university biobanks begin like other university research projects, that is, with an idea conceived by an individual researcher in pursuit of his/her own research interests, publications, funding, and career. Some biobanks, however, come to have scientific value that goes beyond the projects that were initially responsible for the collection of the samples and data they contain. Such value may derive from among other things the uniqueness of the samples in terms of their sheer volume, the quality of the samples, the ability to link the samples with information retrieved in disease registries, or the fact that the samples represent very rare diseases...

This study investigates the possible causes for low development of blastocysts in vitrified immature oocytes by evaluating the changes of mitochondrial membrane potential and reactive oxygen species (ROS) production and finds a recovery mechanism for these conditions in vitrified immature oocytes. To recover from the cryoinjury, we cultured vitrified immature oocytes in milrinone containing medium for 1, 3, and 5 hours and then extended the culture for oocyte maturation. There was no difference in in vitro maturation and fertilization rate between fresh and vitrified/warmed oocytes...

BACKGROUND: Ex vivo cold storage of red blood cells (RBCs) for transfusion has long been associated with hypothermic storage lesions. It has been proposed that liposomes can be used to mitigate hemorheological elements of RBC membrane storage lesions. This study aimed to determine the appropriate liposome treatment time and assess the effects of liposome treatment on RBC's hemorheological and metabolic profiles. MATERIALS AND METHODS: Unilamellar liposomes were synthesized to contain a bilayer of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC):cholesterol (7:3 mol%)...
