A system has been developed to electronically tag and track test tubes used in biorepositories. The system is based on a light-activated microtransponder, also known as a "p-Chip." One of the pressing problems with storing and retrieving biological samples at low temperatures is the difficulty of reliably reading the identification (ID) number that links each storage tube with the database containing sample details. Commonly used barcodes are not always reliable at low temperatures because of poor adhesion of the label to the test tube and problems with reading under conditions of frost and ice accumulation...

The National Institute of Mental Health (NIMH) has made sustained investments in the development of genomic resources over the last two decades. These investments have led to the development of the largest biorepository for psychiatric genetics as a centralized national resource. In the realm of genomic resources, NIMH has been supporting large team science (TS) consortia focused on gene discovery, fine mapping of loci, and functional genomics using state-of-the-art technologies. The scientific output from these efforts has not only begun to transform our understanding of the genetic architecture of neuropsychiatric disorders, but it has also led to a broader cultural change among the investigator community towards deeper collaborations and broad pre-publication sharing of data and resources...

Imputation of human leukocyte antigen (HLA) alleles from SNP-level data is attractive due to importance of HLA alleles in human disease, widespread availability of genome-wide association study (GWAS) data, and expertise required for HLA sequencing. However, comprehensive evaluations of HLA imputations programs are limited. We compared HLA imputation results of HIBAG, SNP2HLA, and HLA*IMP:02 to sequenced HLA alleles in 3,265 samples from BioVU, a de-identified electronic health record database coupled to a DNA biorepository...

CONTEXT: The promising perspective of storing dried blood spot (DBS) for evaluating 25-hydroxyvitamin D (25OHD) levels is increasingly being realized. While strong correlations have been demonstrated between 25OHD levels measured in DBS and in systemic serum samples in earlier works, the clinical concordance of the assay results has not been evaluated. Moreover, the utility of dried serum spot (DSS), a highly suitable matrix for sample archiving, has not been investigated in this respect...

RATIONALE: Pulmonary complications after hematopoietic stem cell transplant (SCT) are associated with increased mortality. Genetic markers for those at risk for pulmonary impairment post-SCT have not been widely investigated. METHODS: Forty-nine patients were retrospectively selected from a single institution's biorepository with linked clinical data. All subjects performed pre-SCT PFTs. Genotyping was conducted using the Infinium Exome-24 BeadChip. Four single nucleotide polymorphisms (SNPs) were selected (rs1800871, rs1695, rs1800629, rs12477314) and evaluated for association with PFT parameters as change over time from baseline...

A biorepository of human samples is essential to support the research of life science. Lymphoblastoid B cell line (LCL), which is easy to be prepared and can reproduce indefinitely, is a convenient form of sample preservation. LCLs are established from human B cells transformed by Epstein-Barr virus (EBV). Chinese National Immortalized Cell Bank has preserved human LCLs from different ethnic groups in China. As there are many studies on the nature of LCLs and public available resources with genome-wide data for LCLs, they have been widely applied in genetics, immunology, pharmacogenetics/genomics, regenerative medicine, cancer pathogenesis and immunotherapy, screening and generation of fully human neutralizing monoclonal antibodies and study on EBV pathogenesis...

Patients enrolled in the African American Study of Kidney Disease and Hypertension (AASK) Cohort Study who exhibited overt proteinuria have been reported to show high nonalbumin proteinuria (NAP), which is characteristic of a tubulopathy. To determine whether African American Study of Kidney Disease and Hypertension nephropathy (AASK-N) is a tubulopathy, we obtained urine samples of 37 patients with AASK-N, with 24-hour protein-to-creatinine ratios (milligrams per milligram) ranging from 0.2 to 1.0, from the National Institute of Diabetes and Digestive Kidney Diseases repository and tested for seven markers of tubular proteinuria...

Arterial thrombosis is a major and global cause of human death and disability. Considering the socioeconomic costs of arterial thrombosis, identification of biomarkers to predict and detect arterial thrombosis at an early stage is an important public health goal. Platelet extracellular vesicles (PEV) are a new candidate biomarker of arterial thrombosis. PEV can be measured in biorepositories, thereby offering the possibility to validate PEV in multicenter clinical trials. PEV analysis has been hitherto hampered by lack of standardized methodology, but substantial technological improvements of PEV detection techniques have been achieved recently...

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: Pulmonary hypertension (PH) is a common and morbid complication of left heart disease with 2 subtypes: isolated post-capillary pulmonary hypertension (Ipc-PH) and combined post-capillary and pre-capillary pulmonary hypertension (Cpc-PH). Little is known about the clinical or physiological characteristics that distinguish these 2 subphenotypes or if Cpc-PH shares molecular similarities to pulmonary arterial hypertension (PAH). OBJECTIVES: The goal of this study was to test the hypothesis that the hemodynamic and genetic profile of Cpc-PH would more closely resemble PAH than Ipc-PH...
