(De Gruyter, 2018-06-21)Foodborne illnesses have been a heavy burden in the United States and globally. Many medicinal herbs have been cultivated in the US and many of which contain antimicrobial compounds with the potential to be used for food ... -
The Lyme disease spirochete's BpuR DNA/RNA-binding protein is differentially expressed during the mammal-tick infectious cycle, which affects translation of the SodA superoxide dismutase
(2019-07)When the Lyme disease spirochete, Borrelia burgdorferi, transfers from a feeding tick into a human or other vertebrate host, the bacterium produces vertebrate-specific proteins and represses factors needed for arthropod ... -
Two of the three Transformer-2 genes are required for ovarian development in Aedes albopictus
(2019-06)In Drosophila melanogaster, transformer-2 (tra2) plays an essential role in the sex-specific splicing of doublesex (dsx) and fruitless (fru), two key transcription factor genes that program sexual differentiation and ... -
Comparison of Common Analytical Methods for the Quantification of Total Polyphenols and Flavanols in Fruit Juices and Ciders
(2019-07-17)Multiple analytical methods are used for quantification of total polyphenols and total flavanols in fruit juices and beverages. Four methods were evaluated in this study: Folin-Ciocalteu (F-C), Lowenthal permanganate (L-P), ... -
Internalization of Erythrocyte Acylpeptide Hydrolase Is Required for Asexual Replication of Plasmodium falciparum
(American Society for Microbiology, 2019-05-08)The human malaria parasite Plasmodium falciparum causes disease as it replicates within the host's erythrocytes. We have found that an erythrocyte serine hydrolase, acylpeptide hydrolase (APEH), accumulates within developing ... -
Public, animal, and environmental health implications of aquaculture
(1997-10)Aquaculture is important to the United States and the world's fishery system. Both import and export markets for aquaculture products will expand and increase as research begins to remove physiologic and other animal ... -
Integrating Nutrition Content into High School Courses: Sample Lesson Plans for Teachers
(Virginia Tech, 2019-08-19)Obesity and overweight are common in the United States. The Centers for Disease Control and Prevention suggest that obesity affects 1 in 5 adolescents in the United States and may lead to an increased risk for a variety ... -
Cache Valley Virus in Aedes japonicus japonicus Mosquitoes, Appalachian Region, United States
(2018-03)We detected Cache Valley virus in Aedes japonicus, a widely distributed invasive mosquito species, in an Appalachian forest in the United States. The forest contained abundant white-tailed deer, a major host of the mosquito ... -
La Crosse Virus in Aedes japonicus japonicus Mosquitoes in the Appalachian Region, United States
(2015-04)La Crosse virus (LACV), a leading cause of arboviral encephalitis in children in the United States, is emerging in Appalachia. For local arboviral surveillance, mosquitoes were tested. LACV RNA was detected and isolated ... -
Student Athlete Leadership Institute
(Virginia Tech, 2019-08-18)The purpose of this project was to determine if Virginia Tech’s Leadership Institute is helping student athletes in their overall experience. Additionally, the project sought to identify which parts of the Leadership ... -
Genotyping by low-coverage whole-genome sequencing in intercross pedigrees from outbred founders: a cost-efficient approach
(2019-08-14)Abstract Background Experimental intercrosses between outbred founder populations are powerful resources for mapping loci that contribute to complex traits i.e. quantitative ... -
From Bright Bodies to iChoose: Using a CBPR Approach to Develop Childhood Obesity Intervention Materials for Rural Virginia
(2019-03-21)This community-based participatory research (CBPR) project used a collaborative process to develop a culturally relevant workbook for parents of overweight children. We followed a mixed methods iterative process to assess ... -

(PLOS, 2016-04)Aedes aegypti, the primary vector of dengue, yellow fever and Zika flaviviruses, consists of at least two subspecies. Aedes aegypti (Aaa) is light in color, has pale scales on the first abdominal tergite, oviposits in ... -
Cooler Temperatures Destabilize RNA Interference and Increase Susceptibility of Disease Vector Mosquitoes to Viral Infection
(PLOS, 2013-05)Background: The impact of global climate change on the transmission dynamics of infectious diseases is the subject of extensive debate. The transmission of mosquito-borne viral diseases is particularly complex, with climatic ... -
Effects of La Crosse virus infection on the host-seeking behavior and levels of two neurotransmitters in Aedes triseriatus
(2019-08-09)Abstract Background La Crosse virus (LACV) infection has been shown to manipulate the blood-feeding behaviors of its main vector, Aedes triseriatus. Here, we investigated the ... -
Mixed methods evaluation of implementation and outcomes in a community-based cancer prevention intervention
(2019-08-05)Abstract Background Community-based educational programs can complement clinical strategies to increase cancer screenings and encourage healthier lifestyles to reduce cancer ... -
Optimization of sand fly embryo microinjection for gene editing by CRISPR/Cas9
(PLOS, 2018-09)Background Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 technology has rapidly emerged as a very effective tool for gene editing. Although great advances on gene editing in the medical entomology ... -
Using Hyperspectral and Multispectral Indices to Detect Water Stress for an Urban Turfgrass System
(MDPI, 2019-08-08)Spectral reflectance measurements collected from hyperspectral and multispectral radiometers have the potential to be a management tool for detecting water and nutrient stress in turfgrass. Hyperspectral radiometers collect ... -
