The extinction rate of mammalian species has been accelerated in recent decades. It therefore is important to preserve and store genetic materials in cryobanks for research purposes and subsequent production of offspring through assisted reproductive techniques. Along with the systematic collection and storage of germplasm, research efforts focusing on in vitro culture to produce mature gametes are critical. Specifically, obtaining mature oocytes from in vitro culture of preantral follicles is a great option to enhance female fertility preservation since these early follicles represent 90%-95% of the follicular population on ovarian cortex biopsy...

Precision medicine has received increased attention as an effective approach for the treatment of cancer patients. Because of challenges associated with the availability of archived tissue, liquid biopsies are often performed to detect cancer-specific mutations. One of the major advantages of the liquid biopsy is that the treatment can be monitored longitudinally, even after the tumor tissue is no longer available. In a clinical setting, one component of precision medicine is the detection of cancer-specific mutations using archived samples...

Ancient human remains may exist as intact cadavers in various forms, including mummies as well as humid or soft corpses. These valuable human depositories have been increasingly investigated with modern molecular biological approaches, delivering breakthrough discoveries in the field of paleoanthropology. Many ancient remains are also preserved in museums for public education of the history of human civilization. The Mawangdui tomb No. 1 cadaver was unearthed in 1972 in Changsha, China, and is a well-preserved humid-type corpse of a deceased woman who lived in the Western Han Dynasty (206BC-24AD)...

Legal and ethical demands for more transparent and strict data protection measures to enhance research participant privacy have grown with an increasing number of human biobanks providing biomaterial collections long term for unspecified future research questions. The design of a data protection scheme that minimizes the risk of donor reidentification and promotes biomaterial and data use in research is a big challenge to all kinds of human biobanks. Yet, there is a lack of publications which address this basic building block of a biobank...

BACKGROUND: It is widely assumed that the integrity of tissue specimens remains stable indefinitely if preserved at cryogenic temperatures. With biobanking reaching a level of maturity where samples are increasingly stored for 10 years and beyond, this assumption of prolonged stability should be tested. Data from such an assessment are critical to verify if samples stored for extended durations remain "fit for purpose" or if there is need to reconsider the utility of samples stored beyond a certain timeframe...

Production of quality seeds is a critical need, and cryopreservation serves as an important biotechnological tool in achieving that goal. In the present study, the effects of different extenders and dilution ratios on the spermatological and fertilization parameters of cryopreserved milt were evaluated in common carp brooders. Milt was collected from Cyprinus carpio brooders and diluted and cryopreserved at three dilution ratios such as 1:40, 1:80, and 1:120, using Freshwater Fish Saline (FWFS) and Modified Fish Ringer as extenders and dimethyl sulfoxide as cryoprotectant (90:10)...

The emergence of biobanks has expanded the scope of biomedical research, ushering in an era of "precision medicine" to improve the treatment of disease. However, biobanks also face sustainability challenges comprising three dimensions-"financial," "operational," and "social." The Taiwan Biobank (TWB), as a large-scale national biobank that supplies valuable phenotypic and genetic information to biomedical researchers on an application basis to investigate the relationship among personal health, genes, lifestyle, environment and diseases of the Taiwanese population, has not been sufficiently explored by researchers...

During pulmonary resections, removal of visceral pleura is frequently required, resulting in lung air leakage (LAL) and bleeding. Especially persistent LAL after pulmonary surgery has negative consequences. Current surgical procedures are ineffective in closing these visceral pleural injuries. Previously, the authors' laboratory has developed a novel and effective LAL sealant using tissue-engineered cell sheets harvested from temperature-responsive culture dishes. The clinical application of fresh fibroblast sheets (FSs) is limited by several problems related to the cell culture period, mass production, preservation, and transportation...

The occurrence of cryoinjuries during ovarian tissue freezing necessitates development of methods that can overcome these challenges in cell and tissue cryopreservation. It has been hypothesized that omega-3 and vitamin E diet supplementation to the animal could be an appropriate strategy to preserve post-thaw ovarian quality. The laying hen is an appropriate animal model that can be used to study the effects of providing dietary supplements on the outcomes of ovary cryopreservation. The purpose of the study was to evaluate the dietary effects of fish oil, sunflower oil, and vitamin E on 68 laying hens according to the following treatments: basal diet + 1...

BACKGROUND: Researchers and other key stakeholders in biobanking often do not have a thorough understanding of the true costs and challenges associated with initiating, running, and maintaining a biobank. The National Cancer Institute's Biorepositories and Biospecimen Research Branch (BBRB) commissioned the Biobanking Financial Sustainability survey to better understand the challenges that biobanks face in supporting ongoing operations. A series of interviews with biobanking managers and an international focus group session informed the content of the survey...

We examined whether the introduction of an audit and feedback strategy applied to specimens dissected at the John Hunter Hospital anatomical pathology department improved the number of formalin fixed tumor specimens sampled by anatomical pathology registrars for the Hunter Cancer Biobank. During the audit period (1/7/16 to 30/6/17) a total of 949 tumor specimens were sampled for the biobank compared with 393 of the previous year (1/7/15 to 30/6/16) resulting in a 141% increase in specimens biobanked. A targeted group of previously underrepresented specimen types, including brain, lung, and lymph node tumors were studied in depth to establish which specimens were sampled and which potentially biobankable specimens were "missed"...

The effect of Equex STM® paste supplementation on the Tris-extender for collared peccaries' semen cryopreservation was assessed. Semen from 12 mature individuals was obtained by electroejaculation and evaluated for morphology, membrane integrity, osmotic response, and sperm kinetic metrics. Samples were diluted in Tris plus 20% egg yolk and divided into three aliquots. The first aliquot was without any supplementation, the second and third contained 0.5 and 1.0% Equex STM, respectively. The samples were added with 3% glycerol, frozen in liquid nitrogen, thawed, and assessed for the same parameters after a thermal resistance test (TRT) for 120 minutes...

Neotropical carnivores include a large number of threatened and endangered species. It is critical to develop conservation efforts to ensure the sustainability of populations in situ and ex situ. The highest priorities are to protect natural habitats and better understand the biology of rare species. Conservation efforts also are directed toward the implementation of breeding programs and the development of reproductive biotechnologies in which the cryopreservation of male gametes plays a major role. It also is fundamental to create semen banks that contribute to maintaining genetic diversity in small and endangered populations...

Tumor biobanks have become critical components of the cancer research infrastructure. Consideration of how to place appropriate values on tumor biobanks is important for all stakeholders. At the level of individual biobanks, value is important in determining how to contribute to, utilize, and fund biobanks. At the level of the research system, value is important in determining how to evaluate, rationalize, and sustain or modify the investments in this infrastructure. This review considers approaches and indicators for evaluation of a biobank with a particular focus on utilization, as one important indicator of value, from the perspective of the researcher and funder...

Many classic biobanks collect more human tissues than they distribute, leading to increased inventories, unnecessary storage, increased expenses, and reduced chargeback income. This situation is a result of biobanks operating without well-defined goals, having incorrect views of the potential number of investigators who will utilize specimens, and collection of biospecimens without adequately considering the need for specific tissues by investigators. These deficiencies frequently lead to unrealistic plans for biospecimen utilization and biobanks that are larger than necessary...
