Development of low cost, easy-to-use chemical sensor systems for low dose detection of γ radiation remains highly desired for medical radiation therapy and nuclear security monitoring. We report herein on a new fluorescence sensor molecule, 4,4'-di(1H-phenanthro[9,10-d]imidazol-2-yl)biphenyl (DPI-BP), which can be dissolved into halogenated solvents (e.g., CHCl3, CH2Cl2) to enable instant detec...
The redox state of the heme of soluble guanylate cyclase (sGC) may regulate the sensitivity of vascular tissue to nitric oxide (NO). In this study, diphenyliodonium (DPI) is used as an inhibitor of flavoprotein oxidoreductases to examine their potential role in the expression of NO-elicited cGMP-associated arterial relaxation and sGC stimulation. The relaxation of endothelium-removed bovine cor...
The probability of detecting influenza A virus (IAV) by virus isolation (VI), point-of-care (POC) antigen detection, and real-time reverse-transcription polymerase chain reaction (rRT-PCR) was estimated for pen-based oral fluid (OF) and individual pig nasal swab (NS) specimens. Piglets (n=82) were isolated for 30 days and confirmed negative for porcine reproductive and respiratory syndrome viru...
Porcine epidemic diarrhea virus (PEDV) is associated with clinical diarrhea in naïve swine of all ages. This report describes timing of antibody generation and disease progression following infection with a US PEDV isolate by assessing fecal viral shedding, morphometric analysis of intestinal lesions, and magnitude of immunohistochemical staining. Sixty-three, 3-week-old pigs were randomly allo...
BACKGROUND An optimal inhalation flow pattern is essential for effective use of a dry powder inhaler (DPI). We wondered whether DPI instructors inhale from a DPI with an appropriate pattern, and if not, whether self-training with visual feedback is effective. METHODS Subjects were 14 pharmacists regularly engaged in instruction in DPI use. A newly designed handy inhalation flow visualizer (Vi...
Experimental inoculations of approximately 100,000 infective Toxocara cati larval eggs were done in twelve pigs. The T. cati eggs used for inoculation were collected from cat's feces. Another group of three pigs served as an uninfected control. Groups of infected pigs were euthanized at seven, 14, 21, and 28 days post-inoculation (dpi). Tissue samples were taken for digestion and histopathology...
Aedes aegypti is the primary vector of dengue, an arboviral disease caused by dengue virus (DENV) that exists as four distinct serotypes (DENV 1-4). While all DENV circulate in Kenya, differential distribution specific regions suggests transmission may differ among local populations. In this study, we tested hypothesis a coastal Ae. population (Rabai, Kilifi County) varies its ability to transm...
Newly emergent turkey arthritis reoviruses (TARV) were isolated from tendons of lame 15-week-old tom turkeys that occasionally had ruptured leg tendons. Experimentally, these TARVs induced remarkable tenosynovitis in gastrocnemius tendons of turkey poults. The current study aimed to characterize the location and the extent of virus replication as well as the cytokine response induced by TARV du...
In the recent years pulmonary drug delivery system is found to be preferred route of administration for various drugs. It has been divided into 3 classes: Nebulizers, pMDI, DPI.DPI are used as an alternative to pMDI because pMDI contains propellant (CFC) which has ozone depletion characteristics. DPI delivers medication in the form of dry powder to lungs. DPI is formulated either as a carrier b...
To determine whether vesicular stomatitis virus (VSV) infection of Culicoides sonorensis Wirth & Jones (Diptera: Ceratopogonidae) affects subsequent blood-feeding behavior, midges injected with either virus-infected or virus-free cell lysates were allowed to blood feed for short (10-min) or long (60-min) periods on 2, 3, and 4 d postinoculation (DPI). Generalized linear mixed models were fit to...
