Understanding protein adsorption kinetics to surfaces is of importance for various environmental and biomedical applications. Adsorption bovine serum albumin self-assembled monolayer including neutral charged hydrophilic hydrophobic was investigated using in-situ combinatorial quartz crystal microbalance with dissipation spectroscopic ellipsometry. varied as a function surface properties, concentration pH value. Charged exhibited greater quantity adsorption, larger layer thickness, increased...
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....
We propose a simple causal model depicting relationships involved in dissemination of antibiotics and antibiotic resistance agroecosystems potential effects on human health, functioning natural ecosystems, agricultural productivity. Available evidence for each link is briefly summarized, key knowledge gaps are highlighted. A lack quantitative estimates exposure to environmental bacteria, general, antibiotic-resistant specifically, significant data gap hindering the assessment health. The...
Supplements and growth promotants containing steroid hormones are routinely administered to beef cattle improve feeding efficiency, reduce behavioral problems, enhance production. As a result, manure will contain both synthetic steroids as well range of endogenous including androgens, estrogens, progestogens. A two-year controlled study was conducted in which were via subcutaneous implants feed additives the occurrence 16 metabolites evaluated runoff from feedlots soil collected feedlot...
<h3>Importance</h3> Scalable programs for school-based SARS-CoV-2 testing and surveillance are needed to guide in-person learning practices inform risk assessments in kindergarten through 12th grade settings. <h3>Objectives</h3> To characterize infections staff students an urban public school setting evaluate test-based strategies support ongoing assessment mitigation learning. <h3>Design, Setting, Participants</h3> This pilot quality improvement program engaged 3 schools Omaha, Nebraska,...
Abstract Land-applied municipal biosolids, produced from wastewater treatment sludge, contributes to microplastics contamination in agroecosystems. The impacts of biosolids on microplastic concentrations agricultural soil have been previously investigated, however, the potential for transport biosolid-amended croplands has not quantified. In this study, manure and were applied field plots, runoff was collected following natural precipitation events bacterial biofilm grow different...
Abstract Polar organic chemical integrative samplers (POCIS) are useful in monitoring for a wide range of chemicals aquatic systems; however, lack available uptake rate data compounds environmental interest is one limitation the application these to studies. In this study, laboratory calibration experiments were conducted with POCIS 65 at 25°C under flowing conditions determine chemical‐specific rates ( R s ). Experimental measured study ranged from 0.034 1.33 L/d, and determined 36 no...
The environmental spread of antibiotics and antibiotic resistance genes (ARGs) from the land application livestock wastes can be a potential public health threat. objective this study was to assess effects setback distance, which determines how close manure may applied in relation surface water, on transport ARGs runoff soil following swine slurry. Rainfall simulation tests were conducted field plots covered with wheat residues, each contained an upslope region where slurry adjacent...
The beef cattle industry in the United States has been using a variety of growth-promoting steroids and steroidlike compounds (GPSCs) to improve growth rates, feed efficiency, lean muscle mass since 1954 (Raun Preston 1997). Almost 96% placed feedlots receive one or more GPSC treatments (USDA 2000). Although there are number natural used as GPSCs, synthetic often potent biologically active than their analogs (Preston 1999). After administration, portion these metabolites excreted into...
