Use Of Calcium Hypochlorite As A Sanitizer For Seeds Used For Sprouting: Task #2; Impact: Improved Alfalfa Decontamination Technologies, Emily Damron, Carrie Klein, Melissa Leach, Jordan Mourot, Tom Murphy, Amy Seamans, Ryan Wilson

Inquiry: The University of Arkansas Undergraduate Research Journal

Consumption of raw or lightly cooked alfalfa sprouts has been a concern of the U.S. Food and Drug Administration (FDA) in recent years due to connections between sprouts and foodborne illnesses. Researchers have identified, contaminated seeds as the primary source of alfalfa sprouts contamination. Contamination of alfalfa seeds can originate in the field, harvesting, storing, or sprouting. Two pathogens of particular concern on alfalfa seeds are Escherichia coli 0157:H7 (E. coli) and Salmonella. These pathogens are capable of producing biofilms that provide protection for individual cells and allow for survival in otherwise hostile environments, including some disinfectant washes. Other factors …

Small Fish Species Of Arkansas Reservoirs, Thomas M. Buchanan Jan 2005

Small Fish Species Of Arkansas Reservoirs, Thomas M. Buchanan

Journal of the Arkansas Academy of Science

Sixty-six Arkansas reservoirs were sampled with rotenone from 1997 through 2004 to determine the distribution and species richness of small, nongame fish species in manmade lentic environments. Eighty-five small fish species distributed among 13 families were collected. Fish distribution and species richness varied by reservoir size, ecoregion, and reservoir type. Species richness was significantly correlated with reservoir size and the number of small species occurring in reservoir drainages. Some small species apparently maintained breeding populations in reservoirs, other species occurred in low numbers and may not have maintained breeding populations, and some species occurred sporadically, probably as stragglers from nearby …

Distribution Of Bats In Bottomland Hardwood Forests Of The Arkansas Delta Region, H. Bobby Fokidis, Stephen C. Brandebura, Thomas S. Risch Jan 2005

Distribution Of Bats In Bottomland Hardwood Forests Of The Arkansas Delta Region, H. Bobby Fokidis, Stephen C. Brandebura, Thomas S. Risch

Journal of the Arkansas Academy of Science

Bat distribution data is incomplete for the delta region of Arkansas. We extensively surveyed 16 counties within the Mississippi alluvial plain that comprises the delta from late spring to early fall 2004 using mist nets. We obtained 44 new county records for 9 species: Myotis lucifigus, M. austroriparius, Pipistrellus subflavus, Eptesicus fuscus, Lasiurus seminolus, L. borealis, L. cinereus, Nycticeius humeralis, and Corynorhinus rafinesquii. We generated updated distribution maps for these species and eastward Arkansas range expansions were documented for L.seminolus. Possible sampling concerns and research directions are discussed in relation to the needs of bats inhabiting bottomland forests of the …

Synthesis And Evaluation Of New Cathepsin D Inhibitors, Rose M. Mcconnell, Walter E. Godwin, Kelley Sayyer, Carol Trana, Adam Green, Matthew Mcconnell, Ashley Young, Lauren Young, Susan E. Hatfield

Journal of the Arkansas Academy of Science

Cathepsin D, a lysosomal aspartic protease, has been suggested to play a role in the metastatic potential of several types of cancer A high activated cathepsin D level in breast tumor tissue has been associated with an increased incidence of relapse and metastasis. High levels of active cathepsin D have also been found in colon cancer, prostate cancer, uterine cancer, and ovarian cancer. Hydroxyethyl isosteres with cyclic tertiary amine have proven to be clinically useful as inhibitors of aspartyl proteases, such as cathepsin D and the HIV1 aspartyl protease. Also cathepsin D has recently been associated with the development of …

Seasonal Incidence Of Sperm Within The Spermathecae Of Ouachita Dusky Salamanders (Desmognathus Brimleyorum) In Arkansas, Stanley E. Trauth, Michelle N. Mary Jan 2005

Seasonal Incidence Of Sperm Within The Spermathecae Of Ouachita Dusky Salamanders (Desmognathus Brimleyorum) In Arkansas, Stanley E. Trauth, Michelle N. Mary

Journal of the Arkansas Academy of Science

We examined 91 adult female Ouachita dusky salamanders {Desmognathus brimleyorum) to determine the seasonal incidence of sperm within spermathecae. The spermatheca (sperm storage gland) along with supporting tissue was removed from the dorsal cloacal wall of each female and prepared for light microscopy. We recorded the reproductive condition of females (diameter of enlarged ovarian follicles =EOF) and found large aggregates of sperm within the spermathecae during all months, except February (no specimens available). The highest incidence of sperm in spermathecae occurred in July specimens (53%; n = 17). Although the known nesting season runs from July into August in this …

Level And Source Of Supplemental Selenium For Beef Steers, Scott Fry, Elizabeth B. Kegley, M. Ellen Davis, Michael D. Ratcliff, Douglas L. Galloway, Ron A. Dvorak Jan 2005

Level And Source Of Supplemental Selenium For Beef Steers, Scott Fry, Elizabeth B. Kegley, M. Ellen Davis, Michael D. Ratcliff, Douglas L. Galloway, Ron A. Dvorak

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Selenium (Se) is deficient in many Arkansas soils; therefore, an experiment was conducted on steers to evaluate the effects of two supplemental Se sources on performance, blood metabolites, and immune function. Thirty Angus-crossbred steers were blocked by weight and assigned within block to one of 15 pens (two steers/pen). Pens were assigned randomly within blocks to one of three dietary treatments consisting of a corn-soybean meal supplement devoid of supplemental Se (negative control, NC) or corn-soybean meal supplements providing 1.7 mg supplemental Se/d as sodium selenite (inorganic Se, ISe) or as Se yeast (organic Se, OSe). Steers were offered fescue …

Growth And Development Of Tomato Seedlings In Sphagnum Peat, Vermiculite, And Processed Rice Hull Substrates, Matthew K. Nutt, Michael R. Evans Jan 2005

Growth And Development Of Tomato Seedlings In Sphagnum Peat, Vermiculite, And Processed Rice Hull Substrates, Matthew K. Nutt, Michael R. Evans

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Tomato (Lycopersicum esculentum ‘Early Girl’) seedling growth was evaluated in substrates containing varying proportions of ground rice hulls. Substrates were formulated containing 0, 30, 60, and 90% ground rice hulls with one-half of the treatments also treated with a surfactant. Seedling growth in two of the ground rice hull-containing substrates was generally similar to the two controls of 90% peat or 100% vermiculite. The germination percentages for all ground rice hull-containing substrates were similar to the two controls. Ground rice hulls are a viable alternative to peat and vermiculite seedling substrates.

Effect Of Social Status Of Dairy Heifers On Expression Of Estrus And Subsequent Fertility, Dawn A. Elkins, Rick W. Rorie Jan 2005

Effect Of Social Status Of Dairy Heifers On Expression Of Estrus And Subsequent Fertility, Dawn A. Elkins, Rick W. Rorie

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

A study was conducted to determine if social status of heifers within a herd influences estrus activity and subsequent fertility. Thirty cyclic dairy heifers were observed over a 14 d period and ranked by social status, based on a displacement index. The estrous cycles of the heifers were synchronized by treatment with two injections of prostaglandin F2a (PGF2a; Lutalyse, 25 mg) given 14 d apart. At the second PGF2a injection, HeatWatch transmitters were placed on the heifers for continuous monitoring of mounting (estrus) activity over the next 45 d. All heifers were artificially inseminated at estrus, using semen from a …

Abnormalities In The Ozark Hellbender, (Cryptobranchus Alleganiensis Bishopi) In Arkansas: A Comparison Between Two Rivers With A Historical Perspective, Waylon R. Hiler, Benjamin A. Wheeler, Stanley E. Trauth Jan 2005

Abnormalities In The Ozark Hellbender, (Cryptobranchus Alleganiensis Bishopi) In Arkansas: A Comparison Between Two Rivers With A Historical Perspective, Waylon R. Hiler, Benjamin A. Wheeler, Stanley E. Trauth

Journal of the Arkansas Academy of Science

We documented abnormalities of Ozark hellbender (Cryptobranchus alleganiensis bishopi) populations in the Eleven Point River (Randolph County, Arkansas) and the Spring River (Fulton County, Arkansas) as part of ongoing monitoring efforts in this species. We found abnormalities in 90% (9 of 10) and 40% (36 of 97) of hellbenders in the Spring River and Eleven Point River, respectively, during the 2003-2004 field seasons. Most abnormalities found in Eleven Point hellbenders were generally less invasive and seemed to be more intrinsic to the species' natural history (i.e., vicissitudes of living), whereas those found in Spring River hellbenders were gross morphological aberrations. …
