Allografts are used to compensate for bone defects resulting from revision surgery, tumor surgery, and reconstructive bone surgery. Although it is well known that the reduction of fat content of allografts increases mechanical properties, the content of liquids with a known grain size distribution has not been assessed so far. The aim of the study was to compare the mechanical properties of dried allografts (DA) with allografts mixed with a saline solution (ASS) and with allografts mixed with blood (AB) having a similar grain size distribution...

Whole genome amplification (WGA) has become an invaluable method for preserving limited samples of precious stock material and has been used during the past years as an alternative tool to increase the amount of DNA before library preparation for next-generation sequencing. Myelodysplastic syndromes (MDS) are a group of clonal hematopoietic stem cell disorders characterized by presenting somatic mutations in several myeloid-related genes. In this work, targeted deep sequencing has been performed on four paired fresh DNA and WGA DNA samples from bone marrow of MDS patients, to assess the feasibility of using WGA DNA for detecting somatic mutations...

INTRODUCTION: Biobanking is a relatively new concept in the Arab region. Targeting different stakeholders to introduce the concept of biobanking and develop an acceptance of it among them is important for the growth of biobanking in the region. Undergraduate students of life sciences represent an important segment of stakeholders, since they constitute potential future biobank customers. Limited funding, lack of awareness of the existence of the term "biobanking" itself among these students, and questions regarding best marketing strategies presented challenges to planning for the most effective message delivery to this target group...

Well-prepared and preserved freshly frozen specimens are indispensable materials for clinical studies. To manage specimen quality and to understand the factors potentially affecting specimen quality during preservation processes, we analyzed the quality of RNA and genomic DNA of various tissues collected between 2002 and 2011 in Linkou Chang Gung Memorial Hospital, Taiwan. During this period, a total of 1059 freshly frozen specimens from eight major cancer categories were examined. It was found that preservation duration, organ origin, and tissue type could all influence the quality of RNA samples...

The development of biomedical research urgently needs the support of a large number of high-quality clinical biospecimens. Therefore, human biobanks at different levels have been established successively in China and other countries at a significantly increasing pace in recent years. To better understand the general current state of clinical biobanks in China, we surveyed 42 clinical biobanks based in hospitals and collected information involving their management systems, sharing mechanisms, quality control systems, and informational management systems using closed questionnaire methods...

In the present study, we examined various freezing protocols, effects of controlled seeding, and changes in cooling rate and determined the endpoint (temperature at which sample could be plugged into liquid nitrogen (LN) without visible effect on survival rate after thawing) to reveal the relative importance of each different stage of cooling on freezing success during cryobanking of carp sperm. Sperm samples from different individual carp males were frozen in 0.5 mL straws by conventional freezing. Cooling rates were determined by monitoring the sample's internal temperature...

Biobanking of organs by cryopreservation is an enabling technology for organ transplantation. Compared with the conventional slow freezing method, vitreous cryopreservation has been regarded to be a more promising approach for long-term storage of organs. The major challenges to vitrification are devitrification and recrystallization during the warming process, and high concentrations of cryoprotective agents (CPAs) induced metabolic and osmotic injuries. For a theoretical model based optimization of vitrification, thermal properties of CPA solutions are indispensable...

The addition of antioxidants to semen cryopreservation extenders has been employed for combating oxidative damage. This work aimed to evaluate the addition of carotenoid canthaxanthin to a cryopreservation extender of ram semen. Three breeder rams were used and, after semen collection, with 48-hour intervals between collection, the samples were included in the pool formation (n = 6). The experimental groups comprised 0 (control), 0.1, 1, 10, and 25 μM of canthaxanthin. After thawing (37°C/30 s) and incubation at 37°C for 2 hours, semen aliquots from each group were evaluated for sperm kinetics (CASA), the integrity of the plasma and acrosomal membranes (iPAM), intracellular reactive oxygen species (ROS) production, and lipid peroxidation (LPO) by flow cytometry associated with the image...

All organizations are subject to risk and uncertainty. Adverse events may disrupt normal organizational activity and may even cause complete failure of business operations. Biorepositories are also at risk and there have been instances where multiple samples or entire collections have been destroyed. Biobank guidelines accordingly recommend the establishment of contingency plans to reduce risk to an acceptable level. In this review article, we will use general theory on risk management and illustrate how such principles can be used to establish a practical crisis management plan for any biobank organization...

BACKGROUND: Serum samples are widely used in clinical research, but a comprehensive research of the stability of parameters relevant to chronic hepatitis and the effect of a relatively long-term (up to 10 years) storage on the stability have rarely been studied. AIMS: To investigate the stability of chronic hepatitis-related parameters in serum samples after long-term storage. MATERIALS AND METHODS: The storage stability of common clinical parameters such as total bile acid (TBA), total bilirubin (TBIL), potassium, cholesterol, and protein parameters such as alanine aminotransferase (ALT), creatine kinase (CK), γ-glutamyltransferase (GGT), albumin, high-density lipoprotein (HDL) and also hepatitis B virus (HBV) DNA, hepatitis C virus (HCV) RNA, hepatitis B surface antigen (HBsAg), and chemokine (C-X-C motif) ligand 10 (CXCL10) were tested in serum samples after storing at -20°C or -70°C for 1, 2, 3, 7, 8, and 10 years...
