Blood samples are an excellent source of large amounts of genomic DNA. However, alternative sources are often needed in epidemiological studies because of difficulties in obtaining blood samples.

This protocol is designed to provide blood, buccal mucosa and bone marrow aspirate samples from approximately 250, healthy volunteer donors for use in in vitro studies of mast cells, masto...
We propose to conduct a pilot study among 30 volunteers from the Division of Cancer Epidemiology and Genetics (DCEG) in order to: (1) select the urine pH strip that most closely correlate...
The goal of this study is to establish a genetic registry of patients with early-onset motor neuron and neuromuscular diseases. The investigators will collect samples from patients with a ...
All eligible subjects were randomly assigned to group A and group B sequences, each sequence has 12 subjects. The SP2086 were given limosis,then after the meal,then limosis.In the study ,t...
This is a randomized non-blinded comparison of dorsal vs. ventral approach for buccal mucosa graft urethroplasty in the bulbar urethra. Buccal mucosa graft is a common method of repairing ...
Telomere length has garnered interest due to the potential role it may play as a biomarker for the cellular aging process. Telomere measurements obtained from blood-derived DNA are often used in epide...
An acceptable area for collecting DNA reference sample is a part of the forensic DNA analysis development. The aim of this study was to evaluate skin surface cells (SSC) as an alternate source of refe...
The human microbiota is postulated to affect cancer risk, but collecting microbiota specimens with prospective follow-up for diseases will take time. Buccal cell samples have been obtained from mouthw...
MicroRNAs (miRNAs) are small regulatory non-coding RNAs for which altered expression in cancers can serve as potential biomarkers for diseases. We here investigated whether circulating miRNAs can serv...
The cells of buccal epithelium were investigated in groups of smoking and non-smoking students. Cell samples were collected by scraping with blunt sterile spatula, stained with orcein and photographed...
Works consisting of collected letters by or about a person or on a subject.
Administration of a soluble dosage form between the cheek and gingiva. It may involve direct application of a drug onto the buccal mucosa, as by painting or spraying.
Testing erythrocytes to determine presence or absence of blood-group antigens, testing of serum to determine the presence or absence of antibodies to these antigens, and selecting biocompatible blood by crossmatching samples from the donor against samples from the recipient. Crossmatching is performed prior to transfusion.
The narrow passage way that conducts the sound collected by the EAR AURICLE to the TYMPANIC MEMBRANE.
The preparation and analysis of samples on miniaturized devices.
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
