From Development To Evolution: The Re-Establishment Of The "Alexander Kowalevsky Medal", A. T. Mikhailov, Scott F. Gilbert

Biology Faculty Works

The Saint Petersburg Society of Naturalists has reinstated the Alexander O. Kowalevsky Medal. This article announces the winners of the first medals and briefly reviews the achievements of A.O. Kowalevsky,the Russian comparative embryologist whose studies on amphioxus, tunicates and germ layer homologies pioneered evolutionary embryology and confirmed the evolutionary continuity between invertebrates and vertebrates. In re-establishing this international award, the Society is pleased to recognize both the present awardees and the memory of Kowalevsky, whose work pointed to that we now call evolutionary developmental biology.

Technical Note: The Effect Of Freezing On Warner-Bratzler Shear Force Values Of Beef Longissimus Steaks Across Several Postmortem Aging Periods, B.C. Shanks, D.M. Wulf, R.J. Maddock

Animal Science Faculty Publications

The objective of this study was to compare fresh and frozen protocol procedures for Warner- Bratzler shear force (WBSF) determination on steaks aged for different periods of time. The fresh protocol consisted of measuring WBSF on steaks cooked on the exact day the aging period ended. The frozen protocol consisted of measuring WBSF on steaks that were aged, frozen (−16°C) for approximately 2 mo, thawed for 24 h, and then cooked. Twenty-two strip loin steaks from each of 20 crossbred heifers and steers were individually vacuum-packaged and assigned to either the fresh or frozen protocol and one of 11 aging …

Genesis And Morphology Of Soil Pendants In Quaternary Landforms Of Pahranagat Valley, Nevada, Amy Lynn Brock

UNLV Theses, Dissertations, Professional Papers, and Capstones

Five geomorphic surfaces present in the northern Pahranagat Valley, Lincoln County, Nevada range in age from Early Pleistocene to Recent (Q1-Q5) and vary in clast lithology from dolomite to volcanic tephras. Two chronosequences and 5 lithosequences were compared to evaluate micro and macromorphic characteristics and development of soil pendants. This study presents a new interpretation for soil pendant development. Key features observed in the Pahranagat Valley pendants provide evidence for precipitation at the clast-pendant contact suggesting that newer deposits are not always found at the pendant terminus as other studies have assumed. These features include a void at the clast-pendant …

Repellency Of Live Potted Plants Against Anopheles Gambiae From Human Baits In Semi-Field Experimental Huts, Aklilu Seyoum, Ephantus W. Kabiru, Wilber Lwande, Gerry F. Killeen, Ahmed Hassanali, Bart G.J. Knols

All Peer-Reviewed Publications

The repellency of potted plants against the malaria vector Anopheles gambiae sensu stricto Giles was quantified in experimental huts under semi-field conditions inside a screen-walled greenhouse. Ocimum americanum Linnaeus (Labiatae), Lantana camara L. (Verbenaceae), and Lippia uckambensis Spreng (Verbenaceae) repelled at an average of 39.7% (95% confidence interval [CI] = 29.6-48.4%), 32.4% (95% CI = 19.7-43.1%), and 33.3% (95% CI = 21.5-43.3%) of the mosquitoes, respectively (P < 0.0001 for all treatments). This was determined by logistic regression, allowing for variations associated with different bait hosts, sampling huts, and replicate test nights. In contrast, Ocimum kilimandscharicum Guerke (Labiatae), Ocimum suave Willd. (Labiatae), Corymbia citriodora Hook (Myrtaceae), Azadirachta indica A. Juss (Meliaceae), Tagetes minuta L. (Asteraceae), and Hyptis suaveolens Poit. (Lamiaceae) did not significantly repel mosquitoes. The combination of O. americanum with either L. camara or L. uckambensis repelled 31.6% (95% CI = 19.7-41.7%) and 45.2% (95% CI = 34.7-54.0%) of the mosquitoes, respectively (P < 0.0001 for both treatments). This study is the first to show that live intact plants can reduce domestic exposure to malaria vector mosquitoes. As such, they may represent a new, sustainable and readily applicable malaria vector control tool for incorporation into integrated vector management programs.

All Peer-Reviewed Publications

The ovicidal activity of eight isolates of entomopathogenic hyphomycetes was evaluated in the laboratory against Maruca vitrata and Clavigralla tomentosicollis. At a concentration of 1 × 108 conidia ml-1, four isolates (Beauveria bassiana CPD 3 and 10, and Metarhizium anisopliae CPD 5 and 12) were found to be highly pathogenic to eggs of M. vitrata, achieving 89-100% mortality. At a given concentration, three isolates (B. bassiana CPD 9 and M. anisopliae CPD 5 and 12) were highly pathogenic to eggs of C. tomentosicollis, achieving 91-94% mortality. These isolates also caused high larval and nymphal mortality (94-100% in M. vitrata and …

A Correlational Analysis Of Anthropometric Measures And Selected Blood, Immune And Endocrine Indices In Adult Males, Janet Tracey Peterson

Loma Linda University Electronic Theses, Dissertations & Projects

Over the past few decades it has become apparent that increased body weight, specifically body fat, coupled with a sedentary lifestyle is associated with an increased risk for chronic disorders such as cardiovascular disease and diabetes. Researchers are now re-directing their focus on determining the cause of these relationships from an epidemiological view to a more biological or physiological standpoint. The purpose of this cross sectional study was to examine associations among obesity, physical activity and select immune, endocrine and metabolic parameters identified as risk factors for several chronic conditions. Ninety-one healthy males between the ages of 19 and 45 …

Il-10 And Alveolar Bone Loss, Abdulaziz Saud Al-Rasheed

Loma Linda University Electronic Theses, Dissertations & Projects

Interleukin-10 (IL-10) is a cytokine with anti-inflammatory activities. IL-10 knockout (KO) mice exhibit severe intestinal inflammation in the presence of normal gut flora. We hypothesized that IL-10 KO mice would also be susceptible to inflammatory periodontal disease resulting in alveolar bone loss (ABL). The purpose of this study was to compare naturally occurring ABL in IL-10 KO and wild type (WT) mice. Twelve IL-10 KO and 12 WT mice, age-(7 months) and sex-(male) matched, were used. Half of the mice were on 129/SvEv and half on C57BL/6J background. Animal heads were defleshed and treated to remove all organic material. ABL …

Identification Of Hard Tissue Using Dentin Sialoprotein (Dsp) As A Marker, Wallis E. Andeline

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to identify the early hard tissue formed in experimental pulp exposures capped with calcium hydroxide, mineral trioxide aggregate (MTA) or bone morphogenetic protein-7 (BMP-7) using dentin sialoprotein (DSP) as a marker. The pulps of eighty-five maxillary first, second and third molar teeth from twenty male rats were experimentally exposed. The exposed pulps were capped with calcium hydroxide followed by restoration with amalgam (n = 20), with MTA alone as a pulp capping agent and final restoration (n = 20) or with BMP-7 followed by restoration with MTA (n = 20). Ten teeth with Class …

The Biophysical Limitations In Physiological Transport And Exchange In Plants Grown In Microgravity, D. M. Porterfield

Biological Sciences Faculty Research & Creative Works

This paper describes how changes in the physical behavior of fluids and gases in microgravity can limit the physiological transport and exchange in higher plants. These types of effects are termed indirect effects of microgravity because they are not due to gravity interacting with the mass of the plant body itself. The impact of limiting gravity-dependent transport phenomena has been analyzed by the use of mathematical modeling to simulate and compare biophysical transport in the 1g and spaceflight environments. These data clearly show that the microgravity environment induces significant limitations on basic physiological and biochemical processes within the aerial and …

Simple, Compact Source For Low-Temperature Air Plasmas, D. P. Sheehan, J. Lawson, M. Sosa, Richard A. Long

Faculty Publications

A simple, compact source of low-temperature, spatially and temporally uniform air plasma using a Telsa induction coil driver is described. The low-power ionization discharge plasma is localized (2 cm X 0.5 cm X 0.1 cm) and essentially free of arc channels. A Teflon coated rolling cylindrical electrode and dielectric coated ground plate are essential to the source’s operation and allow flat test samples to be readily exposed to the plasma. The plasma is a copious source of ozone and nitrogen oxides. Its effects on various microbes are discussed.

Eicosanoids Mediate Manduca Sexta Cellular Response To The Fungal Pathogen Beauveria Bassiana: A Role For The Lipoxygenase Pathway, Jeffrey C. Lord, Sheri Anderson, David W. Stanley

Department of Entomology: Faculty Publications

Many studies have documented the involvement of eicosanoids in insect cellular immune responses to bacteria. The use of the fungal pathogen Beauveria bassiana as a nodulation elicitor, with inhibition of phospholipase A2 by dexamethasone, extends the principle to fungi. This study also provides the first evidence of involvement of the lipoxygenase (LOX) pathway rather than the cyclooxygenase (COX) pathway in synthesis of the nodulation mediating eicosanoid(s). The LOX product, 5(S)- hydroperoxyeicosa-6E,8Z,11Z,14Z-tetraenoic acid (5-HPETE), substantially reversed nodulation inhibition caused by dexamethasone and the LOX inhibitors, caffeic acid and esculetin. The COX product, prostaglandin H₂ (PGH₂), did not reverse …

Effect Of Duration Of Performance Test On Variance Component Estimates For Lamb Growth Rate, G. D. Snowder, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

The objective was to determine the effect of periods of adjustment and duration of performance test on estimating genetic variance parameters for ADG. Variance components were estimated from ADG data collected from 1978 to 1984 on a total of 1,047 Targhee ewe and ram lambs at the U.S. Sheep Experiment Station (Dubois, ID). Across all years, lambs averaged 84 ± 9 d of age and 25 ± 5.4 kg of weight when placed on test. Lambs were provided ad libitum access to a commercial pellet of barley grain and ground alfalfa for 14 wk. Every 2 wk, ADG was recorded. …

Customizing Conception: A Survey Of Preimplantation Genetic Diagnosis And The Resulting Social, Ethical, And Legal Dilemmas, Jason Christopher Roberts

Duke Law & Technology Review

One in six American couples experience difficulties conceiving a child. With fertility rates at an all time low, the business of treating infertility is booming. However, due to the United States prohibition on government funding for embryonic research, the $4 billion industry of assisted reproductive technologies (ART) has been incompletely monitored and largely removed from oversight. Additionally, due to the fervent abortion debate, in vitro fertilization (IVF) was introduced in the United States without a research phase and procedures have been forced to evolve in the private sector. Thus, the checks and balances on medical innovation that are generally imposed …
