Due to the use of antimicrobials in livestock production, residual and antimicrobial resistance genes (ARGs) could enter environment following land application animal wastes further contaminate surface groundwater. The objective this study was determine effect various manure methods on fate transport ARGs soil runoff swine slurry. Swine slurries were obtained from facilities housing pigs that fed chlortetracyline, tylosin or bacitracin applied via broadcast, incorporation, injection methods....
Background: The cholesterol‐lowering drug simvastatin has been shown to stimulate murine calvarial bone growth after multiple injections. purpose of this study was test if similar stimulation could be induced by 2 single‐dose delivery systems appropriate periodontal therapy. Methods: ICR Swiss mice were treated with the following protocols: 1) injection methylcellulose gel alone, subcutaneously over calvarium (INJ‐GEL; n = 8); 2) (INJ‐SIM; 2.2 mg, 16); 3) polylactide membrane (PLA)...
Little is known about physiological mechanisms that underlie the cost of reproduction. We tested hypothesis stress susceptibility a In one test our hypothesis, Drosophila melanogaster females were exposed to juvenile hormone analog (methoprene) stimulate egg production followed by assays. A sterile stock D. was employed as control for Exposure fertile methoprene resulted in an increase female reproduction and increased oxidative starvation (compared solvent controls). Sterile did not exhibit...
Abstract Cornstarch, at 20% moisture content (dry basis, d.b.), was mixed with glycerol 3:1 ratio to form the base material for extruded starch films. Stearic acid, sucrose and urea, varying concentrations, were tested as secondary plasticizers starch‐glycerol mixture. The ingredients 110 120°C barrel temperatures determine effects of extrusion temperature, plasticizer type their concentrations on film‐forming characteristics starch, well selected physical functional properties mechanical...
Abstract Excretal deposition concentrates nutrients in animal watering and resting areas of pastures, including these soil sampling may bias fertilizer recommendations. Our objective was to determine the magnitude extent nutrient enhancement near a water source each two experimental tall fescue ( Festuca arundinacea Schreb.) pastures. The rectangular 0.44‐ha pastures were southcentral Iowa included three soils: fine, montmorillonitic, mesic Typic Argiaquoll, fine‐loamy, mixed, Argiudoll,...
The inherent spatial heterogeneity and complexity of antibiotic-resistant bacteria antibiotic resistance (AR) genes in manure-affected soils makes it difficult to sort out that can be attributed human use from occurs naturally the soil. This study characterizes native Nebraska prairie have not been affected by or food-animal waste products provide data on background levels southeastern Nebraskan soils. Soil samples were collected 20 sites enumerated tetracycline cefotaxime media; screened...
Abstract Aim To compare the apical density of several obturation techniques when used in palatal roots extracted maxillary molars. Methodology Seventy molars were randomly divided into seven groups with 10 teeth each. The root canals instrumented to size 60 MAF, coated Kerr's Pulp Canal Sealer, and obturated using one techniques. separated from crowns, decalcified, sectioned horizontally at 2 4 mm apex. cross‐sections photographed through a microscope, photos analysed, amount area canal that...
A study was conducted to assess the effects of varying cage spaces on a commercial laying hen strain fed differing levels dietary metabolizable energy (ME) for 15 wk. Four space allowances (342, 413, 516, and 690 cm2/hen) were combined with 3 ME (2,800, 2,850, 2,900 kcal ME/kg) in 4 × factorial arrangement. Each treatment assigned 6 replicate cages total 72 randomized complete block design. Feed intake significantly (P < 0.01) greater hens housed at cm2/hen compared those 413 342 cm2/hen,...
Information about the potential for crop–wild hybridization is needed to understand how crop genes, including transgenes, affect population genetics and ecology of sexually compatible relatives. Transgenic sorghum under development use by traditional farmers in Africa, center origin [ Sorghum bicolor (L.) Moench], but systematic surveys current extent contact with wild weedy relatives are lacking. We studied sorghums that interfertile constitute a crop–wild–weed complex. The survey was...
