Project description:Crosslinking immunoprecipitation and sequencing was used to characterize nucleocapsid-RNA interactions in Rift Valley fever virus infection. This data set includes illumina HiSeq paired-end reads of Rift Valley fever virus infected HEK293 cells. The sequencing libraries were generated from nucleocapsid-bound RNAs.
Project description:Rift Valley fever virus causes severe disease in humans and livestock and in some cases can be fatal. There is concern about the use of Rift Valley fever virus as a bioweapon since it can be transmitted through the air, and there are no vaccines or antiviral treatments. Airborne transmission of the virus causes severe inflammation of the brain, yet little is known about the immune response against the virus in this organ. Here, we investigated the immune response in the brain to Rift Valley fever virus following intranasal infection. We determined that microglia, the resident immune cells of the brain, initiate a robust response to Rift Valley fever virus infection and identified a key immune pathway that is critical for the ability of microglia to respond to infection. When this immune pathway is rendered non-functional, mice have a dysregulated response to infection in the brain.
Project description:Coccidioides immitis and Coccidioides posadasii are soil-dwelling fungi of arid regions in North and South America that are responsible for Valley fever (coccidioidomycosis). Forty percent of patients with Valley fever exhibit symptoms ranging from mild, self-limiting respiratory infections, to severe, life-threatening pneumonia that requires treatment. Misdiagnosis as bacterial pneumonia commonly occurs in symptomatic Valley fever cases, resulting in inappropriate treatment with antibiotics, increased medical costs, and delay in diagnosis. In this study, we explored the feasibility of developing breath-based diagnostics for Valley fever using lung specimens from persons with community-acquired pneumonia (CAP). To investigate potential volatile biomarkers of Valley fever that arise from host-pathogen interactions, we collected bronchoalveolar lavage fluid (BALF) and sputum from patients treated at Mayo Clinic in Scottsdale, Arizona for untargeted volatile metabolomics via solid phase microextraction (SPME) and two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC×GC-TOFMS). We identified 244 total volatile organic compounds (VOCs). Using Random Forest, we identified a subset of these VOCs that were also able to separate Coccidioides positive samples from bacteria positive samples. The data presented here show that Coccidioides and/or the host produce volatile metabolites that may yield biomarkers for a Valley fever breath test that can detect Coccidioidal infection.

Project description:Images and gpr files were examined using a novel saturation reduction method to determine whether accuracy could be improved by extending dynamic range of saturated pixels Three immunosignatures from human Valley Fever (Coccidiodes) patients and three immunosignatures from human influenza vaccine recipients were examined to test an algorithm that extends the apparent dynamic range of a fluorescence image. These images had several saturated spots at 70PMT and 100% laser power. The program examined the differences between Valley Fever and influenza in terms of standard image processing vs. segmentation and intensity estimation.
Project description:Iso-Seq "full length" transcript sequences were used as one of many guides informing gene model annotation of the Valley Oak genome sequence.
Project description:This pilot study is a 3-arm randomized control trial assessing the effectiveness of sequential or active choice in CRC (colorectal cancer) screening outreach vs. colonoscopy outreach only, in patients between 50-74 years old, who have received care at the University City or Valley Forge CCA (Community Care Associates) practices, are due for screening, and are asymptomatic for CRC. The three arms are: Arm 1: Direct schedule colonoscopy (Control), Arm 2: Direct schedule colonoscopy followed by mailed FIT(Fecal Immunochemical Test) (Sequential Choice), and Arm 3: Choice of direct schedule colonoscopy or mailed FIT (Active Choice).
