The incidence of skin cancer (e.g., squamous cell carcinoma, basal cell carcinoma, and melanoma) has been increasing over the past several years. It is expected that there will be a parallel demand for cutaneous tumor samples for biomedical research studies. Tissue availability, however, is limited due the cost of establishing a biorepository and the lack of protocols available for obtaining clinical samples that do not interfere with clinical operations. A protocol was established to collect and process cutaneous tumor and associated blood and saliva samples that has minimal impact on routine clinical procedures on the date of a Mohs surgery...

Disseminating mouse stocks as frozen materials offers both ethical and logistical advantages over live animal shipment, minimizing the welfare issues and avoiding some of the complex custom regulations that are associated with live animal transportation. Embryo freezing in liquid nitrogen (LN2) at -196 °C has traditionally been the method of choice for archiving mouse lines. However, spermatozoa freezing is emerging as a more convenient alternative due to the application of innovative cryopreservation and recovery protocols...

The Human Heredity and Health in Africa (H3Africa) Consortium is a conglomeration of research and infrastructure projects spread throughout Africa whose aim is to apply genomic methodology to diseases affecting the people in the region. Its operation is innovative in the sense that it is doing something new; that is, filling a hitherto existing void in genomic research capability of African scientists and infusing resources and manpower to institutions and investigators across Africa. But aside from developing and sustaining capacity in genomic research and biorepositories, H3Africa is also invested in developing appropriate ethical regulatory regime to govern research in these areas...

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...
