Nitrogen And Phosphorus Accumulation In Pasture Soil From Repeated Poultry Litter Application, Zhongqi He, C. Wayne Honeycutt, Irenus A. Tazisong, Zachary N. Senwo, Donglin Zhang

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Poultry litter (PL) is a traditionally inexpensive and effective fertilizer to improve soil quality and agricultural productivity. However, over application to soil has raised concern because excess nutrients in runoff could accelerate the eutrophication of fresh water. In this work, we determined the contents of total phosphorus (P), Mehlich 3 extracted P, total nitrogen (N), ammonium (NH4)-N, and nitrate (NO₃)-N, in pasture soils receiving annual poultry litter applications of 0, 2.27, 2.27, 3.63, and 1.36 Mg/ha/ yr, respectively, for 0, 5, 10, 15, and 20 years. Samples were collected from three soil depths (0–20, 20–40, and 40–60 cm) …

Relationships Between Executive Functions, Attention Deficit Hyperactivity Disorder (Adhd), Comorbid Disorders, And Familial History In A Nonclinical Population, Sara M. Sachjog Velez

PCOM Psychology Dissertations

Attention-deficit/hyperactivity disorder (ADHD) is typically characterized by impulsivity, inattention, and hyperactivity and often lasts into adulthood. Depression, anxiety, and bipolar disorder are often diagnosed as comorbid disorders with ADHD. Adults with ADHD may also display executive functioning deficits. The current study sought to identify whether symptoms of executive functioning were related to symptoms of ADHD in adults. It also identified comorbid disorders in the participants. Questionnaires assessing executive functioning, ADHD, depression, anxiety, and bipolar spectrum disorders were given to participants. Demographics were obtained regarding their own background and comorbid disorders in their first-degree relatives. Results indicated that symptoms of executive …

Plant Species Composition And Biofuel Yields Of Conservation Grasslands, Paul R. Adler, Matt A. Sanderson, Paul J. Weimer, Kenneth P. Vogel

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Marginal croplands, such as those in the Conservation Reserve Program (CRP), have been suggested as a source of biomass for biofuel production. However, little is known about the composition of plant species on these conservation grasslands or their potential for ethanol production. Our objective was to assess the potential of CRP and other conservation grasslands for biofuel production, describing the relationships of plant species richness and tall native C₄ prairie grass abundance with plant chemical composition and the resulting potential ethanol yield. We determined plant species composition and diversity at multiple scales with the modified Whittaker plot technique, aboveground …

Transferrin Lipoplex-Mediated Suicide Gene Therapy Of Oral Squamous Cell Carcinoma In An Immunocompetent Murine Model And Mechanisms Involved In The Antitumoral Response, S. Neves, Henrique Faneca, S. Bertin, Krystyna Konopka, Nejat Düzgüneş, V. Pierrefite-Carle, S. Simões, M. C. Pedroso De Lima

All Dugoni School of Dentistry Faculty Articles

Suicide gene therapy has been used for the treatment of a variety of cancers. We reported previously the in vitro efficacy of the Herpes Simplex Virus Thymidine kinase (HSV-tk)/ganciclovir (GCV) system to mediate cytotoxicity in oral squamous cancer cells, using transferrin (Tf)-lipoplexes, prepared from cationic liposomes composed of 1,2-dioleoyl-3-(trimethylammonium) propane (DOTAP) and cholesterol. In the present study, we evaluated the antitumoral efficacy mediated by this lipoplex formulation in two suicide gene therapy strategies, HSV-tk/GCV and cytosine deaminase (CD)/5-fluorocytosine (5-FC), using a syngeneic, orthotopic murine model for head and neck squamous cell carcinoma. The cellular and molecular events associated with the …

Correlation Between The Levels Of Survivin And Survivin Promoter-Driven Gene Expression In Cancer And Non-Cancer Cells, Krystyna Konopka, Christopher Spain, Allison Yen, Nathan Overlid, Senait Gebremedhin, Nejat Düzgüneş

All Dugoni School of Dentistry Faculty Articles

Survivin, a member of the inhibitor of apoptosis (IAP) protein family, is associated with malignant transformation and is over-expressed in most human tumors. Using lipoplex-mediated transfection, we evaluated the activity of the reporter enzyme, luciferase, expressed from plasmids encoding the enzyme under the control of either the cytomegalovirus (CMV) or survivin promoters, in tumor- and non-tumor-derived human and murine cells. We also examined whether there is a correlation between the survivin promoter-driven expression of luciferase and the level of endogenous survivin. Human cancer cells (HeLa, KB, HSC-3, H357, H376, H413), oral keratinocytes, GMSM-K, and chemically immortalized human mammary cells, 184A-1, …

The Immature Stages And Natural History Of Veladyris Pardalis (Salvin, 1869) In Eastern Ecuador (Lepidoptera, Nymphalidae, Ithomiinae), H. F. Greeney, Ryan I. Hill, M. R. Hualinga, W. R. Simbana, G. Gentry

College of the Pacific Faculty Articles

We describe the immature stages and oviposition behavior of Veladyris pardalis (Salvin, 1869) from northeastern Ecuador. An unidentified species of Solanum (Solanaceae) is the larval food plant. Eggs are laid singly on leaves, stems or epiphytes growing on the host. Veladyris pardalis has four larval stadia, and takes 64–70 days to mature from oviposition to adult.

Interpretive Bias In Acupuncture Research? A Case Study, Neil E. O'Connell, Benedict M. Wand, Ben Goldacre

Health Sciences Papers and Journal Articles

Acupuncture is one of the most widely used and broadly researched of the complementary and alternative therapies, but high quality trials generally show no benefit over sham acupuncture. Many would view this result as evidence of ineffectiveness for this intervention.

This discussion paper focuses on the report of one large multi-centre randomised controlled trial of acupuncture for chronic low back pain in the lay and academic press, the ensuing discussion, and its impact on both clinical practice and service provision.

We suggest that interpretive bias has affected reporting, leading to questionable conclusions and advocacy in favour of this form of …

Biodegradation Of 2-Chlorophenol Using Free And Immobilized Laccase From Trametes Versicolor / Swapna Sambrani, Sambrani Swapna

Student Works (2000-2009)

Laccase from white rot fungus Trametes versicolor was immobilized in sodium alginate beads using entrapment method. Kinetic parameters (Vmax and Km) of both free and immobilized laccase were determined using syringaldazine as substrate. 2- chlorophenol was degraded using free and immobilized laccase. An indirect rapid assay method was developed for the assay of degraded products of 2-chlorophenol, wherein the anionic phenoxy radicals, possibly generated during 2-chlorophenol degradation, couples with a cationic dye, Methylene Blue and renders it colorless. The extent of decolorization indicated the extent of product formation and hence the extent of 2-chlorophenol degradation assuming a 1:1 stoichiometric reaction …

The Effect Of Heating On The Antioxidants Content In Edible Oil / Premanand A/L Krishnan, Krishnan Premanand

Student Works (2000-2009)

There are many types edible oils with various brand found in the market. The types of oils involved in the analysis for the antioxidants content were palm oil, olive oil, canola oil, sunflower oil, soy bean oil, corn oil, gingerly oil, rice bran oil, mixed oil and ayurvedic oil. The method used to evaluate the amount antioxidants in this study was 2, 2-diphenyl-1-picrylhydrazyl (DPPH). In this test, the scavenging of the DPPH radicals was followed by monitoring the decrease in absorbance at 515 nm. Heating the oil samples to various temperatures shows negative effect on the antioxidants content. The antioxidants …
