Project description:This study mapped the genome wide DNA methylation changes in whole blood and buccal swab samples of 2 year old male rhesus monkeys subjected to parental deprivation in their first months of life (surrogate peer-reared condition).
Project description:The objectives of this study were to establish a microbiome profile for oral epithelial dysplasia using archival lesion swab samples to characterize the community variations and the functional potential of the microbiome using 16S rRNA gene sequencing
Project description:The ongoing SARS-CoV-2 pandemic and subsequent demand for viral testing worldwide has led to major issues in scaling the efforts of diagnostic labs and even in securing basic supplies for collection and processing of samples. This has in turn led to worldwide efforts by the scientific community to establish improved protocols that are cheaper, more scalable, and not as resource intensive. One such effort resulted in an assay called “Swab-Seq”, which was so named because it was originally developed to work with dry nasal swab samples, but is actually flexible in terms of the sample type it can accommodate for testing. The assay adapts the existing gold standard (RNA extracted from a nasopharyngeal (NP) swab that is subjected to quantitative reverse transcription polymerase chain reaction, “qRT-PCR”) to a next-generation sequencing readout. By pairing this modification with extraction-free sampling techniques it is possible to achieve high scalability at low cost per sample, and a reasonable turnaround time for reporting results. We evaluated the effectiveness of this assay both on samples collected from asymptomatic individuals using the traditional NP swab and using alternative extraction-free sampling techniques, including saliva and a saline mouth gargle protocol, and found the assay to be highly sensitive (comparable to the standard qRT-PCR assay), flexible (adaptable to saliva and gargle samples stored at room temperature up to a week), and scalable (easily accommodating hundreds of samples at a time). Continued development in the future will lead to more effective testing regimes that reduce the burden of transmissible respiratory infections on the global community.
Project description:Genome-wide expression profiling of four kinds of body fluid samples (blood, saliva, semen and vaginal swab). The purpose of the present study was selection of specific mRNA markers for identification of the four body fluids. Results provide important information about gene expression level of each body fluid for forensic science.
