A global synthesis reveals biodiversity-mediated benefits for crop production
(AAAS, 2019-10)Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related ecosystem services can be maintained by a few dominant species or rely on ... -
Complete Dosage Compensation in Anopheles stephensi and the Evolution of Sex-Biased Genes in Mosquitoes
(Oxford University Press, 2015-06-09)Complete dosage compensation refers to hyperexpression of the entire X or Z chromosome in organisms with heterogametic sex chromosomes (XYmale or ZW female) in order to compensate for having only one copy of the X or Z ... -
CoSpliceNet: a framework for co-splicing network inference from transcriptomics data
(BMC, 2016)Background: Alternative splicing has been proposed to increase transcript diversity and protein plasticity in eukaryotic organisms, but the extent to which this is the case is currently unclear, especially with regard to ... -
A novel Gateway®-compatible binary vector allows direct selection of recombinant clones in Agrobacterium tumefaciens
(BMC, 2011-12-07)Background: Cloning genes into plasmid vectors is one of the key steps for studying gene function. Recently, Invitrogen™ developed a convenient Gateway® cloning system based on the site-specific DNA recombination properties ... -
Mitochondrial Dysregulation in Skeletal Muscle from Patients Diagnosed with Alzheimer’s Disease and Sporadic Inclusion Body Myositis
(Scientific Research Publishing, 2014-05)Mitochondrial dysfunction is implicated in Alzheimer’s disease (AD) and disruption of mitochondrial dynamic pathways has been documented in brains from patients diagnosed with AD; although it is unclear whether other tissues ... -
Development of Efficient Plant Regeneration and Transformation System for Impatiens Using Agrobacterium tumefaciens and Multiple Bud Cultures as Explants
(BMC, 2010-08-09)Background: Impatiens (Impatiens walleriana) is a top selling floriculture crop. The potential for genetic transformation of Impatiens to introduce novel flower colors or virus resistance has been limited by its general ... -
Expression of mitochondrial branched-chain aminotransferase and α-keto-acid dehydrogenase in rat brain: implications for neurotransmitter metabolism
(Frontiers Media, 2012-05-28)In the brain, metabolism of the essential branched chain amino acids (BCAAs) leucine, isoleucine, and valine, is regulated in part by protein synthesis requirements. Excess BCAAs are catabolized or excreted. The first step ... -
Nhlh2 is a Cold-Responsive Gene
(Bentham Open, 2010)Nescient helix-loop-helix 2 (Nhlh2) is a basic helix-loop-helix transcription factor that functions to communicate signals of energy availability. Based on the expression pattern of Nhlh2 in cold-sensitive areas of the ... -
Feasibility, effectiveness, and perceptions of an Internet- and incentive-based behavioral weight loss intervention for overweight and obese college freshmen: A mixed methods approach
(2013)Challenges inherent with the transition to col- lege are often accompanied by weight gain among college freshmen. Weight gain and dura- tion of obesity increase metabolic syndrome and cardiovascular disease risk in young ... -
Gamma Irradiation Influences the Survival and Regrowth of Antibiotic-Resistant Bacteria and Antibiotic-Resistance Genes on Romaine Lettuce
(Frontiers Media, 2019-04)Contamination of romaine lettuce with human pathogens, antibiotic-resistant bacteria (ARB), and antibiotic resistance genes (ARGs) occurs during production. Post-harvest interventions are emplaced to mitigate pathogens, ... -
Microbiota and Antibiotic Resistome of Lettuce Leaves and Radishes Grown in Soils Receiving Manure-Based Amendments Derived From Antibiotic-Treated Cows
(Frontiers Media, 2019-04-10)Cattle are commonly administered antibiotics, resulting in excretion of antibiotics, antibiotic-resistant bacteria (ARB), and antibiotic resistance genes (ARGs). The aim of this study was to determine if the use of dairy ... -

(PLOS, 2019-09-19)The identification and separation of cells from heterogeneous populations is critical to the diagnosis of diseases. Label-free methodologies in particular have been developed to manipulate individual cells using properties ... -
N-(3-oxododecanoyl)-L-homoserine lactone interactions in the breast tumor microenvironment: Implications for breast cancer viability and proliferation in vitro
(PLOS, 2017-07-10)It is well documented that the tumor microenvironment profoundly impacts the etiology and progression of breast cancer, yet the contribution of the resident microbiome within breast tissue remains poorly understood. Tumor ... -
Dose-Dependent Phytotoxicity of Pesticides in Simulated Nursery Runoff on Landscape Nursery Plants
