Stress-Induced Attenuation Of Acoustic Startle In Low-Saccharin-Consuming Rats., Clinton Chapman, Nancy Dess, Mitzi Gonzales, Cameryn Garrett

Clinton D Chapman

Exposure to stress can lead to either increased stress vulnerability or enhanced resiliency. Laboratory rats are a key tool in the exploration of basic biobehavioral processes underlying individual differences in the effect of stress on subsequent stressors' impact. The Occidental low (LoS) and high (HiS) saccharin-consuming rats, which differ in emotional reactivity, are useful in this effort. In the present study, footshock affected acoustic startle amplitude 4 h later among LoS but not HiS rats. Surprisingly, shock attenuated startle rather than sensitizing it, a finding not previously reported for male rats exposed to shock. Attenuation was blocked by administering the …

Iron Fertilization Of Kentucky Bluegrass, David Wehner, Jean Haley

David J. Wehner

Iron applications are sometimes used to enhance the color (darker green) of turfgrass stands even when iron is not deficient. A study was conducted to determine the feasibility of replacing a portion of the total yearly N applied to Kentucky bluegrass (Poa pratensis L.) with iron. Turfgrass response to iron chelate (Sequestrene 330) applications at 2.2 kg Fe ha^-1 in combination with three liquid-applied N sources (urea, Formolene, and FLUF) at 25 kg N ha^-1 was compared to turf response from applications of the N sources at 49 kg N ha^-1. Iron was substituted for …

Honey Bees: A History, Tammy Horn

Tammy Horn

Long known as the angels of agriculture, honey bees have received global attention due to losses attributed to a combination of factors: Colony Collapse Disorder, mites, deforestation and industrial agriculture. Honey bees provide pollination for crops, orchards and flowers; honey and wax for cosmetics, food and medicinal-religious objects; and inspiration to artists, architects and scientists.

Models For Predicting The Lower Limit Of The Canopy-Air Temperature Difference Of Two Cool Season Grasses, Dennis Martin, David Wehner, C. Throssell

David J. Wehner

Estimation of the lower limit of the canopy-air temperature differential, (T_c–T_a)_LL, is required for calculation of an empirically-based crop water stress, index. This research determined the complexity of model needed for accurate estimation of (T_c–T_a)_LL for several field grown cultivars of Kentucky bluegrass (Poa pratensis L.) and for creeping bentgrass (Agrostis stolonifera L. var. palustris (Huds.) Farw.). Regression models using vapor pressure deficit of the air (VPD), net radiation load (R_n), and wind speed (WS) were developed for predicting (T_c–T_{a …}

Melamine/Urea And Oxamide Fertilization Of Kentucky Bluegrass, David Wehner, Dennis Martin

David J. Wehner

The commercial lawn care industry represents a large market for N sources. A formulated melamine (2,4,6-triamino-s-triazine) plus urea combination (MLU) (45% melamine by weight) and oxamide were evaluated for use by the lawn care industry by comparing turfgrass response from these fertilizers to that from urea, sulfur coated urea (SCU), ureaformaldehyde (Nitroform), and a non-fertilized check. Fertilizers were applied four times per year to field plots of Kentucky bluegrass (Poa pratensis L.) growing on a Flanagan silt loam (fine, montmorillonitic, mesic Aquic Argiudoll) at a rate of 49 kg N ha-1 per application. Color ratings and clipping weights were determined …

Coal Country Beeworks: An Experiment In Apiforestation, Tammy Horn

Tammy Horn

The Coal Country Beeworks promotes a fundamental principle: diverse economies depend on diverse landscapes. In order for the colonial status of Appalachia to change, the unique mesophytic forests that existed prior to mining need to be reestablished so local people can be beekeepers, honey producers, queen rearers,scientists, etc. In this way,the two-tier economy that has defined Appalachia for the past hundred years can be diversified.

Protease Activation Of A2-Macroglobulin Modulates A Chaperone-Like Action With Broad Specificity, Katie French, Justin Yerbury, Mark Wilson

Mark R Wilson

α2-Macroglobulin (α2M) is a major human blood glycoprotein best known for its ability to inhibit a broad spectrum of proteases by a unique trapping method. This action induces an “activated” conformation of α2M with an exposed binding site for the low density lipoprotein receptor, facilitating clearance of α2M-protease complexes from the body. This report establishes that protease activation also modulates a potent chaperone-like action of α2M which has broad specificity for proteins partly unfolded as a result of heat or oxidative stress. Protease-mediated activation of α2M abolishes its chaperone-like activity. However, native α2M is able to form soluble complexes with …
