Valorisation Of The Cider And Brewing Industry By-Products As Nutraceutical Ingredients, Sofia Reis

Doctoral

By-products from the cider and brewing industries, including apple pomace (AP) and brewer’s spent grain (BSG) respectively, constitute major environmental problems due to the large quantities produced every year. They are sources of valuable compounds such as protein, fibre, essential fatty acids, phenolic compounds and minerals, some of them with antioxidant and prebiotic properties. Their high nutritional value leads to their potential use as human food products and several applications have been considered recently. The aims of this work include i) the nutritional and compositional characterisation of AP, BSG and final extruded and baked prototypes containing these by-products and ii) …

Pharmacy Faculty Articles and Research

Several novel N-(9-oxo-9H-xanthen-4-yl)benzenesulfonamides derivatives were prepared as potential antiproliferative agents. The in vitro antiproliferative activity of the synthesized compounds was investigated against a panel of tumor cell lines including breast cancer cell lines (MDA-MB-231, T-47D) and neuroblastoma cell line (SK-N-MC) using MTT colorimetric assay. Etoposide, a well-known anticancer drug, was used as a positive standard drug. Among synthesized compounds, 4-methoxy-N-(9-oxo-9H-xanthen-4-yl)benzenesulfonamide (5i) showed the highest antiproliferative activity against MDA-MB-231, T-47D, and SK-N-MC cells. Furthermore, pentafluoro derivatives 5a and 6a exhibited higher antiproliferative activity than doxorubicin against human leukemia cell line (CCRF-CEM) and breast adenocarcinoma (MDA-MB-468) cells. Structure-activity relationship studies revealed that …

Closing The Knowing-Doing Gap In Invasive Plant Management: Accessibility And Interdisciplinarity Of Scientific Research, Virginia Matzek, Justin Covino, Jennifer L. Funk, Martin Saunders

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Like many conservation disciplines, invasion biology may suffer from a knowing-doing gap, where scientific research fails to inform management actions. We surveyed California resource managers to evaluate engagement with scientific research and to identify research priorities. We examined managers' access to information, judgment of the usefulness of existing research, ability to generate scientific information, and priorities for future research. We found that practitioners rely on their own experience, and largely do not read the peer-reviewed literature, which they regard as only moderately useful. Less than half of managers who do research carry out experiments conforming to the norms of hypothesis …

Connecting Model Species To Nature: Predator-Induced Long-Term Sensitization In Aplysia Californica, Maria J. Mason, Amanda J. Watkins, Jordann Wakabayashi, Jennifer Buechler, Christine Pepino, Michelle Brown, William G. Wright

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Previous research on sensitization in Aplysia was based entirely on unnatural noxious stimuli, usually electric shock, until our laboratory found that a natural noxious stimulus, a single sublethal lobster attack, causes short-term sensitization. We here extend that finding by demonstrating that multiple lobster attacks induce long-term sensitization (>= 24 h) as well as similar, although not identical, neuronal correlates as observed after electric shock. Together these findings establish long-and short-term sensitization caused by sublethal predator attack as a natural equivalent to sensitization caused by artificial stimuli.

Bacon's Swamp- Ghost Of A Central Indiana Natural Area Past, Rebecca W. Dolan

Scholarship and Professional Work - LAS

Bacon’s Swamp was identified in the 1920s as a ca. 12 ha glacial kettle lake bog system at the southernmost limits of these habitats in Indiana. Located just 9.6 km from the center of Indianapolis, the site was all but destroyed in the mid-20th century by urban expansion. Prior to habitat conversion at the site, Bacon’s Swamp was a frequent location for Butler University ecology class field trips and student research projects. Herbarium specimens and published inventory records allow for analysis of the historical vegetation of Bacon’s Swamp using modern techniques. Floristic Quality Assessment applied to these historical records reveals …

Alterations And Specifications Of Excess Post-Exercise Oxygen Consumption: A Review, Genevieve Kocoloski, Anne R. Crecelius

Health and Sport Science Faculty Publications

This review describes oxygen consumption, both in terms of a goal of weight management and aerobic training. It introduces excess postexercise oxygen consumption (EPOC) and the benefits that can come from it. EPOC can aid in weight management as a means to continue to expend energy even after exercise has ceased. This review also discusses the many determinants of EPOC and analyzes the effects of various conditions on the elevated consumption. Such conditions include duration and intensity of exercise, training status, and supplementation. Later discussed are the possible underlying mechanisms and how they are responsible for EPOC. Although they have …

Fate Of Antimicrobials And Antimicrobial Resistance Genes In Simulated Swine Manure Storage, Stacey R. Joy, Xu Li, Daniel D. Snow, John Gilley, Bryan L. Woodbury, Shannon L. Bartelt-Hunt

School of Natural Resources: Faculty Publications

The behavior of three antibiotics (bacitracin, chlortetracycline, and tylosin) and two classes of antibiotic resistance genes (ARGs), tet and erm, were monitored in swine manure slurry under anaerobic conditions. First-order decay rates were determined for each antibiotic with half-lives ranging from1 day (chlortetracycline) to 10 days (tylosin). ARGs were monitored in the swine manure slurry, and losses of approximately 1 to 3 orders of magnitude in relative abundance were observed during the 40 day storage period. First-order degradation profiles were observed for chlortetracycline and its corresponding resistance genes, tet(X) and tet(Q). Tylosin was degraded to approximately 10% …

Fatigue Resistibility And Stimulus Strength Using Intraspinal Microstimulation Vs. Intramuscular Stimulation In A Rat Model: Case Study, John Dube

Honors Theses, 1963-2015

Spinal Cord Injury is a devastating injury that has drastic effects on an individual’s daily living activities. The current devices and methods of direct muscle, peripheral nerve cuff, and epidural stimulation are bulky, easily fatigable, require large stimulation parameters, and/ or difficult to use. Intraspinal Micro stimulation (ISMS) suggests a more fatigue resistant method at lower stimulation parameters that will help restore locomotion, bladder control, and sexual function in an individual. The research conducted herein shows ISMS evokes a linear positive relationship between stimulus strength and muscle contraction force that is comparable to clinically used methods of Intramuscular stimulation. Research …

Occurrence Of Multiple Antibiotic Resistant Bacteria In Aquatic Environments In Central Minnesota, Megan Bollin

Honors Theses, 1963-2015

Antibiotic resistance among bacteria has been a topic of concern for many years. The purpose of this study was to evaluate the occurrence of antibiotic resistance among bacteria found in aquatic environments such as the lakes on the campus of Saint John’s University along with the Sauk River in Cold Spring and St. Joseph, Minnesota. By analyzing samples from different aquatic environments, this data can be used to better identify patterns of resistance within different genera of bacteria. A total of 125 isolates were captured from these different areas and isolated into pure cultures. The isolated cultures were grown on …

A Retrospective Examination Of Paleoparasitology And Its Establishment In The Journal Of Parasitology, Charles T. Faulkner, Karl Reinhard

School of Natural Resources: Faculty Publications

Volume 95 (2009) of the Journal of Parasitology represented a significant benchmark in the history of paleoparasitology when it received on the cover formal recognition as a topical area for publication. This retrospective examination chronicles the emergence of paleoparasitology, from its origins as an adjunct contribution to the study of prehistoric human populations to its modern expression as a sub-disciplinary interest. The aim of paleoparasitology is to elucidate the temporal and spatial dimensions of parasitism from the fossil record of human and non-human host populations.

The Distance From Necessity: A Bourdieusian Analysis Of Gathering Practices In Vermont, Alan Robert Pierce

Antioch University Full-Text Dissertations & Theses

This study examines why contemporary Americans continue to gather wild plants and fungi. Vermont, a state with a rich history of gathering, serves as a study site. I interviewed twenty-four gatherers using ethnographic methods. I applied a Bourdieusian framework to analyze the differences between gathering practices as they related to gathering knowledge, views of nature, and uses of gathered products. The interviews indicated that gathering is important to the physical and mental well-being of its practitioners and instills a connection to nature as well as to place. Interviewees cited spending time in nature and enjoyment of engaging the senses as …

The Costs Of Changing Our Minds, Nita A. Farahany

Faculty Scholarship

This isn’t quite a draft yet – it’s a concept paper. You’ll see after the first 10 pages a good bit of text in brackets, which are primarily notes for me, but it’ll give you a sense of the content of those sections. I’d like to talk through the concept – the “duty” to mitigate emotional distress damages and how courts have struggled with it, as a foray into a broader dichotomy that I see in a number of areas of law that suggest an implicit value in “cognitive liberty.” This is a smaller version of a broader book project …

Grain Finishing Beef: Alternative Rations, Cattle Performance And Feeding Costs For Small Feeders, Dillon M. Feuz, Jesse Russell

All Current Publications

In a feeding trial at Utah State University during the summer of 2013, it was found that cattle had higher ADG when fed SFC compared to whole corn. However, when the relative cost of SFC and whole corn were considered, feeding whole corn compared to SFC resulted in nearly identical feed costs per pound of gain. Actual and relative costs of SFC and whole corn can and do vary over time and across geographic regions. Therefore, feeders could use the information in this fact sheet to determine which feed will be the most economical for them.

Lack Of Equivalence In The Elemental And Stable Isotope Chemistry Within The Sagittal Otolith Pair Of The Summer Flounder, Paralichthys Dentatus, Antranik Kajajian, Jason J. Schaffler, Cynthia M. Jones

OES Faculty Publications

In fish that are not bilaterally symmetrical, the left and right sagittae are often not symmetrical, exhibiting divergent growth patterns and mass, and may have differences in chemical composition. We investigated this in the asymmetrical summer flounder Paralichthys dentatus, collected from different nursery habitats along the US east coast. Significant differences were detected in otolith mass, δ¹³C, δ¹⁸O, Li:Ca, Mg:Ca, and Sr:Ca, and overall chemical signatures. These results refute the hypothesis of left-right equivalence that is prevalent for bilaterally symmetrical fishes. We tested whether a specific side was better suited for classification. The best models …

Effect Of An Herbal/Botanical Supplement On Strength, Balance, And Muscle Function Following 12-Weeks Of Resistance Training: A Placebo Controlled Study, Jonathan Furlong, Corey A. Rynders, Mark Sutherlin, James Patrie, Frank I. Katch, Jay Hertel

Human Movement Sciences & Special Education Faculty Publications

Background: StemSport (SS; StemTech International, Inc. San Clemente, CA) contains a proprietary blend of the botanical Aphanizomenon flos-aquae and several herbal antioxidant and anti-inflammatory substances. SS has been purported to accelerate tissue repair and restore muscle function following resistance exercise. Here, we examine the effects of SS supplementation on strength adaptations resulting from a 12-week resistance training program in healthy young adults.

Methods: Twenty-four young adults (16 males, 8 females, mean age = 20.5 ± 1.9 years, mass = 70.9 ± 11.9 kg, stature = 176.6 ± 9.9 cm) completed the twelve week training program. The study design …

Peroneal Reaction Time After Ankle Sprain: A Systematic Review And Meta-Analysis, Matthew C. Hoch, Patrick O. Mckeon

Human Movement Sciences & Special Education Faculty Publications

Background: Many studies have examined the temporal response of the peroneal muscles to sudden inversion perturbation in patients with a previous ankle sprain. The purpose of this systematic review with meta-analysis was to synthesize the evidence and determine whether peroneal reaction time (PRT) impairments are present after ankle sprain. Methods: An electronic search was conducted using PubMed Central and EBSCOhost (1965-January 2013). Articles were included if they 1) examined the PRT to sudden inversion perturbation in patients with a history of ankle sprain using a mechanical tilt platform, 2) made comparisons with a control group or contralateral limb with no …

High-Intensity Tasks With External Load In Military Applications: A Review, Eric K. O'Neal, Jared H. Hornsby, Kyle J. Kelleran

Human Movement Sciences & Special Education Faculty Publications

This article provides a synopsis of the limited investigations examining the impact of external load (EL) on performance of high-intensity tasks under load (HITL), EL training intervention effects on HITL performance, and injuries from EL training. Repetitive lifting tasks and initiation of locomotion, such as rapidly moving from a prone position to sprinting appear to be more hindered by EL than maximal sprinting velocity and may explain why training with EL does not improve obstacle course or prolonged (200-300 yard shuttle) drills. EL training appears to offer very little if any benefit for HITL in lesser trained populations. This contrast …
