Behavioral Science Faculty Publications

BACKGROUND: Cognitive-behavioral stress management interventions are associated with improved psychological well-being for cancer survivors. The availability of, access to, and outreach of these in-person interventions are limited, however. The current study, therefore, evaluated the efficacy of StressProffen, a digital application (app)-based stress management intervention for cancer survivors, in a 12-month randomized controlled trial.

METHODS: Cancer survivors 1 year or less after their treatment (N = 172) were randomized to the StressProffen intervention (n = 84) or a usual-care control group (n = 88). The intervention was delivered in a simple blended care model: 1) 1 in-person introduction session, 2) 10 …

Fermentation And Cell Wall Degradation In Guineagrass And Italian Ryegrass Silages, Mitsuhiro Niimi, O. Kawamura

IGC Proceedings (1977-2023)

Guineagrass (Panicum maximum Jacq.) was ensiled at the room temperature and Italian ryegrass (Lolium multiflorum L.) was ensiled at the room temperature and at 30 under the laboratory conditions. As a result, the acetic acid silage was made from Guineagrass and the lactic acid silages were made from Italian ryegrass. The loss of cell wall components during ensiling was the most in hemicellulose followed by NDF, but those of cellulose and AD-lignin were slight. In the hemicellulosic monosaccharides, the loss of hexose (galactose and glucose) was relatively high and that of pentose (arabinose and xylose) was relatively low …

Evaluation Of Forage Sorghum Silages With The Addition Of Sorghum Grain, M. De León, E. Ustarroz, M. A. Brunetti, C. Boetto, M. Bulaschevich

IGC Proceedings (1977-2023)

The aim of this experiment was to evaluate the effect of additional sorghum grain and stage of maturity of forage sorghum silage on the animal performance. Two feeding trials were conducted with forage sorghum silage made at different stage of plant maturity. In trial 1, early silage was made with the crop harvested in early bloom stage. Four diets based on different ratios of silage: sorghum grain were evaluated: 100% silage (ES); 80% silage: 20% dry grain (ES20D); 60% silage: 40% dry grain (ES40D) and 60% silage: 40% wet grain silage (ES40W). In trial 2, late silage was made with …

Influence Of Additive Aiv-2000 And Pre-Wilted Big Bale On Silage Quality, Animal Performance And Rumen Metabolism, Jonas Jatkauskas, V. Vrotniakienė

IGC Proceedings (1977-2023)

Silage treatment with AIV-2000 or making of silage big bales resulted in a higher level of lactic acid and organic matter digestibilities and reduced concentrations of butyric acid and ammonia-N. Feeding AIV-2000 treated and big bale silages increased weight gains of young fattening bulls by, respectively, 5.44 and 6.77% in comparison with the ordinary made silage. AIV-2000 treated and big bale silages affected microflora activity in the rumen. Infusoria count was higher by 13.5 and 30.34% (P < 0.05), VFA concentration increased by 0.39 and 8.45%, the pH value decreased by 0.05 and 0.1 unit, the content of total nitrogen was by 14.67 and 18.73 mg/100 ml, protein nitrogen by 14.12 and 16.63 mg/100 ml and non-protein nitrogen by 0.53 and 1.39 mg/100 ml higher, respectively for AIV-2000 and big bale groups in comparison with the control group.

Quality And Nutritive Value Of Mott Dwarf Elephantgrass Silage With Biological Additives, T. Clavero

IGC Proceedings (1977-2023)

This experiment was conducted to study the effects of cellulase enzymes and lactic acid bacteria on the fermentation characteristics, chemical composition and nutritive value of Pennisetum purpureum cv Mott silage. Five kinds of preparation were tested: sugar molasses (control); sugar molasses and cellulase enzymes; cellulase enzymes; concentrate of lactic acid bacteria and sugar molasses and concentrate of lactic acid bacteria. Significant differences (P< 0.05) were found in fermentation quality and chemical composition of control silage as compared to the biological additives treated silage. Addition of cellulase enzymes and lactic acid bacteria resulted in decrease of pH value, cell wall content and increased lactic acid concentration. The biological additives increased silage intake and daily live weight by growing steers.

Effects Of Different Additives On Silage Quality Of Napiergrass, Y. K. Cheng, C. S. Chen, P. W. Peng

IGC Proceedings (1977-2023)

Objectives of this experiment were to determine the effects of different additives on silage quality of napiergrass (Pennisetum purpureum). The cultivar of TLG2 with high water soluble carbohydrates was used to making silages added with or without 5 and 10% corn meal or wheat bran, and then treated with or without enzyme. Crude protein, acid detergent fiber, neutral detergent fiber, water soluble carbohydrates and volatile fatty acid contents of silage were determined to evaluate silage quality. From the results, it showed that var.TLG2 could be making good silages without any additives but the dry matter was low. Adding …

Background: Cerebral glucose hypometabolism is consistently observed in individuals with Alzheimer’s disease (AD), as well as in young cognitively normal carriers of the Ε4 allele of Apolipoprotein E (APOE), the strongest genetic predictor of late-onset AD. While this clinical feature has been described for over two decades, the mechanism underlying these changes in cerebral glucose metabolism remains a critical knowledge gap in the field.

Methods: Here, we undertook a multi-omic approach by combining single-cell RNA sequencing (scRNAseq) and stable isotope resolved metabolomics (SIRM) to define a metabolic rewiring across astrocytes, brain tissue, mice, and human subjects expressing APOE4.

Zinc is an essential cofactor for bacterial metabolism, and many Enterobacteriaceae express the zinc transporters ZnuABC and ZupT to acquire this metal in the host. However, the probiotic bacterium Escherichia coli Nissle 1917 (or “Nissle”) exhibits appreciable growth in zinc-limited media even when these transporters are deleted. Here, we show that Nissle utilizes the siderophore yersiniabactin as a zincophore, enabling Nissle to grow in zinc-limited media, to tolerate calprotectin-mediated zinc sequestration, and to thrive in the inflamed gut. We also show that yersiniabactin’s affinity for iron or zinc changes in a pH-dependent manner, with increased relative zinc binding as the …

A Comparative Study Of Yokeless And Segmented Armature Versus Single Sided Axial Flux Pm Machine Topologies For Electric Traction, Narges Taran, David Klink, Greg Heins, Vandana Rallabandi, Dean Patterson, Dan M. Ionel

Power and Energy Institute of Kentucky Faculty Publications

This article systematically compares two axial flux permanent magnet machines designed for a university student racing car application: a double-rotor single-stator yokeless and segmented armature (YASA) structure, and a single-stator single-rotor configuration. Both machines are optimized for minimum loss and active weight using three-dimensional finite element analysis and the highest performing candidate designs are compared in more detail. The studies indicate that the benefits offered by the YASA configuration over the single-stator single-rotor machine are achieved only for specific designs that are heavier. For the design space with lower mass, albeit with increased losses, the Pareto front designs overlap. In …

Radioresistance In Prostate Cancer: Focus On The Interplay Between Nf-Κb And Sod, Sameera Kumar, Daret St. Clair

Toxicology and Cancer Biology Faculty Publications

Prostate cancer occurs frequently in men and can often lead to death. Many cancers, including prostate cancer, can be initiated by oxidative insult caused by free radicals and reactive oxygen species. The superoxide dismutase family removes the oxygen-derived reactive oxygen species, and increased superoxide dismutase activity can often be protective against prostate cancer. Prostate cancer can be treated in a variety of ways, including surgery, androgen deprivation therapy, radiation therapy, and chemotherapy. The clinical trajectory of prostate cancer varies from patient to patient, but more aggressive tumors often tend to be radioresistant. This is often due to the free-radical and …

Berseem Clover In Binary Mixtures With Oats, Triticale Or Barley For Silage And Late Season Grazing, S. M. Ross, J. R. King

IGC Proceedings (1977-2023)

An experiment was conducted at northerly latitudes with berseem clover (Trifolium alexandrinum L) in binary mixtures with oats (Avena sativa L.), barley (Hordeum vulgare L.) and triticale (X Triticosecale Wittmack). The effects of cereal species, variety and density were assessed for a two cut harvest. Total dry matter yields were 11.7 to 14.5 t ha^-1, with 7.8 to 10.2 t ha^-1 as silage, and 2.0 to 6.0 t ha^-1 as berseem regrowth. Berseem regrowth added an average of 4.0 t ha^-1 in forage yield. Total yields did not differ with cereal …

Forage Productivity Of Panicum Maximum Pastures In Two Different Agropastoral Systems, Tsutomu Kanno, Manuel C. M. Macedo, J. A. Bono, J. D. G. Santos Jr., M. R. Correa, L. G. R. Beretta

IGC Proceedings (1977-2023)

Forage productivity was evaluated for Panicum maximum pastures established after 4 years of soybean cultivation in the summer (PM-SO), and 4 years of rotation of soybeans in the summer and millet for winter grazing (PM-MI). In the PM-MI pasture, biomass and dry matter production were much lower than in the PM-SO, and the amount of copper and nitrogen in the top part of the plants in PM-MI were significantly lower than that in PM-SO. Thus, it was considered that the shortage of copper and nitrogen restricted photosynthesis and forage production in PM-MI.

Nitrogen Mineralization From Root Residues Of Subterranean Clover And Lucerne, T. P. Bolger, J. F. Angus, M. B. Peoples

IGC Proceedings (1977-2023)

To understand why crops grown in the first or second year after lucerne (Medicago sativa L.) yielded less than crops grown after subterranean clover (Trifolium subterraneum L.) despite greater nitrogen (N) fixation by the lucerne, we studied the N mineralization patterns of their root residues in soil incubation assays. Fine roots of both species produced more mineral N than the control soil with no root residues. In contrast, coarse roots mineralized less N than the control soil. These differences in N mineralization were not explained by the physical size and therefore surface area differences between fine and coarse …

Supplementation Of Temperate Pastures, D. H. Rearte, G. A. Pieroni

IGC Proceedings (1977-2023)

Generally in temperate regions, beef and milk were produced on extensive systems with forage from perennial pasture and natural grassland being the main component of animal diet. Supplementation on pasture was usually applied strategically to supply nutrients to grazing cattle only when forage availability was not enough to satisfy animal’s requirements. At present beef and dairy production systems have become more intensive and even when forage from pasture continue being the main component of the diet higher level of different type of supplement are fed to the animals. Intensive systems are characterized by a higher stocking rate capable of consuming …

Feeding Of Conserved Forage - Implications To Grassland Management And Production, C. W. Holmes, P. N. P. Matthews

IGC Proceedings (1977-2023)

This review will focus on the use of conserved forages in pastoral dairy farm systems; especially on their conservation as an aid to good grazing management during periods of rapid pasture growth, and on their consumption as an aid to good feeding management and grazing management during periods of slow pasture growth. Conservation of pasture, in order to move it from one time to another later time, always involves “costs”, either financial expenditure or physical losses (of dry matter/quality) or both, which must be evaluated in the whole system.

Most of the data is drawn from New Zealand and Australia, …
