Educational Attainment, Population Increase And The Progress Of African Americans, Amadu Jacky Kaba 2010 Seton Hall University

Educational Attainment, Population Increase And The Progress Of African Americans, Amadu Jacky Kaba

Amadu Jacky Kaba

This paper claims that African Americans are making consistent progress in college or university enrollment and degree attainment. These gains in educational attainment have led to a substantial proportion of African Americans to rise in many important sectors of society, such as business, the military and politics. However, there is a concern that unlike the Asian and Hispanic populations in the United States, proportionally, the African American population is not increasing as rapidly. This slow annual growth of the African American population may have both economic and political implications in the years and decades to come.

Michelle Obama And The Black Female Diaspora: The Most Influential Black Woman In History?, Amadu Jacky Kaba

Amadu Jacky Kaba

This paper claims that just as President Barack Obama is the most known male member of the Black World in the 21st century, so also his wife First Lady Michelle Obama is the most known female member of this racial group. Also, just as President Obama is the most powerful Black leader in history, so also First Lady Obama is the most influential Black female in history. The paper argues that Both President Obama and First Lady Obama are keeping their 2008 campaign promises to the youth who gave them a very high share of their votes both in the ...


Forced-Exercise Alleviates Neuropathic Pain In Experimental Diabetes: Effects On Voltage-Gated Calcium Channels, Sahadev A. Shankarappa 2010 Loyola University Chicago

Forced-Exercise Alleviates Neuropathic Pain In Experimental Diabetes: Effects On Voltage-Gated Calcium Channels, Sahadev A. Shankarappa

Dissertations

Exercise is now established as an integral adjunct to the management of diabetes. Diabetic polyneuropathy, a painful complication of diabetes, remains untreatable, emphasizing a critical need for improved therapeutic strategies. Recent evidence suggests that exercise may facilitate recovery of peripheral nerve function in diabetes. However, the mechanism by which exercise protects against diabetes-induced nerve dysfunction is unknown. In this dissertation we hypothesized that forced-exercise protects against experimental DPN by preventing glucose-associated alterations of voltage-gated calcium currents (VGCC) in small diameter dorsal root ganglion (DRG) neurons. Using behavioral, nerve-electrophysiology and patch-clamp methodology we examined the functional consequences of forced-exercise (treadmill, 5 ...


Cholinergic Neurons Regulate And Utilize Gdnf Secreted By C2c12 Skeletal Muscle Cells In Culture, John-Mary Vianney, John M. Spitsbergen 2010 Western Michigan University

Cholinergic Neurons Regulate And Utilize Gdnf Secreted By C2c12 Skeletal Muscle Cells In Culture, John-Mary Vianney, John M. Spitsbergen

Biological Sciences Faculty and Graduate Student Research

Glialcell line-derived neurotrophicfactor (GDNF) has been regarded as a potent survival factor for a subpopulation of neurons. It has been shown that GDNF expression is upregulatedin skeletal muscle of patients with early stage of neuromuscular diseases such as amyotrophic lateral sclerosis (ALS). Previous results from our laboratory showed that neural cells regulate GDNF secretion by skeletal muscle; non-innervated skeletal muscle appear to secrete more GDNF compared to innervated skeletal muscle. Two aims were examined in the current study. First, to examine whether neural cells inhibit GDNF through acetylcholine release. Second was to examine whether differentiated NG108-15 neural cells secrete GDNF ...


Short Term Voluntary Exercise Alters Gdnf Protein Expression In Rat Spinal Cord, Monica J. McCullough, John Spitsbergen 2010 Western Michigan University

Short Term Voluntary Exercise Alters Gdnf Protein Expression In Rat Spinal Cord, Monica J. Mccullough, John Spitsbergen

Biological Sciences Faculty and Graduate Student Research

Glial cell line-derived neurotrophic factor (GDNF) is considered to be one of the most potent neurotrophic factors for motor neurons of the spinal cord. However, little is known about the response of GDNF in the spinal cord following exercise from healthy individuals.PURPOSE:Previous studies from our laboratory have shown that long term voluntary exercise (6 weeks and 6 months) has no effect on GDNF protein content in rat spinal cord. Therefore, the aim of the current study was to examine changes in GDNF protein content in the spinal cord following 2 weeks of voluntary exercise from adult and aged ...

Amino Acid Transport In Thermophiles: Characterization Of An Arginine-Binding Protein In Thermotoga Maritima, Matthew S. Luchansky, Bryan S. Der, Sabato D'Auria, Gabriella Pocsfalvi, Luisa Iozzion, Daniela Marasco, Jonathan D. Dattelbaum

Chemistry Faculty Publications

Members of the periplasmic binding protein superfamily are involved in the selective passage of ligands through bacterial cell membranes. The hyperthermophilic eubacterium Thermotoga maritima was found to encode a highly stable and specific periplasmic arginine-binding protein (TM0593). Following signal sequence removal and overexpression in Escherichia coli, TM0593 was purified by thermoprecipitation and affinity chromatography. The ultra-stable protein with a monomeric molecular weight of 27.7 kDa was found to exist as both a homodimer and homotrimer at appreciable concentrations even under strongly denaturing conditions, with an estimated transition temperature of 116 °C. Its multimeric structure may provide further evidence of ...

Distribution Of Eastern Hemlock, Tsuga Canadensis, In Eastern Kentucky And The Susceptibility To Invasion By The Hemlock Woolly Adelgid, Adelges Tsugae, Joshua Taylor Clark 2010 University of Kentucky

Distribution Of Eastern Hemlock, Tsuga Canadensis, In Eastern Kentucky And The Susceptibility To Invasion By The Hemlock Woolly Adelgid, Adelges Tsugae, Joshua Taylor Clark

University of Kentucky Master's Theses

The hemlock woolly adelgid, an invasive non-native insect, is threatening eastern hemlock in Kentucky. This study examined three techniques to map the distribution of eastern hemlock using decision trees, remote sensing, and species distribution modeling. Accuracy assessments showed that eastern hemlock was best modeled using a decision tree without incorporating satellite radiance. Using the distribution from the optimal model, risk maps for susceptibility to hemlock woolly adelgid infestation were created using two species distribution models. Environmental variables related to dispersal were used to build the models and their contributions to the models assessed. The models showed similar spatial distributions of ...

Spiny amaranth is a problematic weed of heavily grazed pastures in Kentucky and surrounding states. The first objective was to evaluate spiny amaranth control when herbicides are applied before and after emergence. Spiny amaranth seed collected in 2008 were seeded in rows in the fall (November) and the following spring (March) in fields located near Lexington and Princeton, KY. Treatments consisted of five application dates and five herbicides plus an untreated control arranged in a split-split plot design. The following parameters were measured: fresh weight, plant height and percent visual control. At both locations pendimethalin applied in November, March and ...


Impact Of High-Input Production Practices On Soybean Yield, Daniel L. Jordan 2010 University of Kentucky

Impact Of High-Input Production Practices On Soybean Yield, Daniel L. Jordan

University of Kentucky Master's Theses

High-input management practices are often heavily marketed to producers to increase soybean [Glycine max (L) Merr.] yield in already high-yielding environments. Field research was conducted in three locations within 6 states (Arkansas, Iowa, Kentucky, Louisiana, Michigan, and Minnesota) in 2009 to determine the effect of seed treatment, inoculant, foliar fungicide, additional soil fertility beyond state recommendations, foliar fertilizer, increased population over state recommendations, and narrow row spacing on yield. The high-input system (combination of the management practices) yielded higher than standard-input system (University recommended management practices) in only 8 of the 18 locations. Narrow rows, in both the high and ...

We evaluated the effects of wearing a weighted vest during 6 weeks of military-style training. Forty-three subjects were randomly assigned to a control group or a vest group (carrying 4-5 kg for 2 weeks, and 8-10 kg for 4 weeks), with 37 completing the study (17 vest, 20 control). Both groups performed stair climbing in addition to standard Marine Corps training for 1 hour, four times per week. Pre- and post-tests were performed while wearing military personal protective equipment, with the exception of the Marine Physical Readiness Test (PRT). Both groups significantly improved PRT scores (8.4% 3-mile run, 28-38 ...

Atmospheric nitrogen (N) deposition is a recognized threat to plant diversity in temperate and northern parts of Europe and North America. This paper assesses evidence from field experiments for N deposition effects and thresholds for terrestrial plant diversity protection across a latitudinal range of main categories of ecosystems, from arctic and boreal systems to tropical forests. Current thinking on the mechanisms of N deposition effects on plant diversity, the global distribution of G200 ecoregions, and current and future (2030) estimates of atmospheric N-deposition rates are then used to identify the risks to plant diversity in all major ecosystem types now ...


How Our Health Depends On Biodiversity, Eric Chivian M.D., Aaron Bernstein M.D., M.P.H. 2010 Center for Health and the Global Environment at Harvard Medical School

How Our Health Depends On Biodiversity, Eric Chivian M.D., Aaron Bernstein M.D., M.P.H.

Ecosystem Disruption & Climate Change

The eminent Harvard biology Professor Edward O.Wilson once said about ants, “We need them to survive, but they don’t need us at all.” The same, in fact, could be said about countless other insects, bacteria, fungi, plankton, plants, and other organisms. This fundamental truth, however, is largely lost to many of us. Rather, we humans often act as if we are totally independent of Nature, as if our driving thousands of other species to extinction and disrupting the life-giving services they provide will have no effect on us whatsoever.

This summary, using concrete examples from our award-winning Oxford ...

The purpose of this study was to examine the efficacy of continuous resistance training (3 days/wk) compared to interrupted resistance training where 20-24 h separated an exercise bout (i.e. 6 days/wk) for enhancing bone mineral density (BMD) in growing male rats. The total volume of work performed per week between the two resistance training programs was equivalent by design. Young male rats were randomly divided into Control (Con, n = 9), 3 days/wk resistance trained group (RT3, n = 9), and 6 days/wk resistance trained group (RT6, n = 9). The RT3 and RT6 groups were conditioned to ...


Hydrogenase-3 Contributes To Anaerobic Acid Resistance Of Escherichia Coli, Joan Slonczewski, Ken Noguchi, Daniel P. Riggins, Khalid C. Eldahan, Ryan D. Kitko 2010 Kenyon College

Hydrogenase-3 Contributes To Anaerobic Acid Resistance Of Escherichia Coli, Joan Slonczewski, Ken Noguchi, Daniel P. Riggins, Khalid C. Eldahan, Ryan D. Kitko

Faculty Publications

Background: Hydrogen production by fermenting bacteria such as Escherichia coli offers a potential source of hydrogen biofuel. Because H2 production involves consumption of 2H+ , hydrogenase expression is likely to involve pH response and regulation. Hydrogenase consumption of protons in E. coli has been implicated in acid resistance, the ability to survive exposure to acid levels (pH 2–2.5) that are three pH units lower than the pH limit of growth (pH 5–6). Enhanced survival in acid enables a larger infective inoculum to pass through the stomach and colonize the intestine. Most acid resistance mechanisms have been defined using ...


Osmolytes Contribute To Ph Homeostasis Of Escherichia Coli, Joan Slonczewski, Ryan D. Kitko, Jessica C. Wilks, Gian M. Garduque 2010 Kenyon College

Osmolytes Contribute To Ph Homeostasis Of Escherichia Coli, Joan Slonczewski, Ryan D. Kitko, Jessica C. Wilks, Gian M. Garduque

Faculty Publications

Background: Cytoplasmic pH homeostasis in Escherichia coli includes numerous mechanisms involving pH-dependent catabolism and ion fluxes. An important contributor is transmembrane K+ flux, but the actual basis of K+ compensation for pH stress remains unclear. Osmoprotection could mediate the pH protection afforded by K+ and other osmolytes. Methods and Principal Findings: The cytoplasmic pH of E. coli K-12 strains was measured by GFPmut3 fluorimetry. The wild-type strain Frag1 was exposed to rapid external acidification by HCl addition. Recovery of cytoplasmic pH was enhanced equally by supplementation with NaCl, KCl, proline, or sucrose. A triple mutant strain TK2420 defective for the ...

On The Mechanism Of Protein Fold-Switching By A Molecular Sensor, Margaret M. Stratton, S N. Loh 2010 University of Massachusetts Amherst

On The Mechanism Of Protein Fold-Switching By A Molecular Sensor, Margaret M. Stratton, S N. Loh

Biochemistry & Molecular Biology Department Faculty Publication Series

Alternate frame folding (AFF) is a mechanism by which conformational change can be engineered into a protein. The protein structure switches from the wild-type fold (N) to a circularly-permuted fold (N'), or vice versa, in response to a signaling event such as ligand binding. Despite the fact that the two native states have similar structures, their interconversion involves folding and unfolding of large parts of the molecule. This rearrangement is reported by fluorescent groups whose relative proximities change as a result of the order-disorder transition. The nature of the conformational change is expected to be similar from protein to protein ...
