Microspore Wall Morphogenesis And Orbicule Ultrastructure Of Isoetes, Khalid Alarid

Biological Sciences Theses & Dissertations

The microspore wall morphogenesis and orbicule ultrastructure of Isoetes were studied using electron microscopy. Microspore wall morphogenesis in five species of Isoetes (I. appalachiana, I. engelmannii, I. hyemalis, I. piedmontana, and an undescribed species from York Co., VA, USA) was studied using scanning and transmission electron microscopy. Results show that they generally have the same developmental stages in terms of microspore wall morphogenesis. The mature microspore wall consisted of four layers: perispore, paraexospore, exospore and endospore. Paraexospore formation began during the tetrad stage. The exospore was then formed between the paraexospore and the plasma membrane. During the free spore …

The Perspective And Practice Of Leadership By Managers Within The Virginia Department Of Corrections: An Instrumental Case Study, Elizabeth M. Gagnon

School of Public Service Theses & Dissertations

This dissertation explores the extent to which the perspective and practice of leadership by managers in the Virginia Department of Corrections (DOC) reflect the Leadership Perspectives Model (LPM), and the extent to which their perspective varies by level of management. The LPM is a model of leadership that consolidates leadership study into five distinct leadership perspectives that managers use in their understanding and practice of leadership. This study builds upon research in which the a LPM was tested and validated within a sample managers from municipal government agencies (M. R. Fairholm, 2004a, 2004b).

The findings of this study reveal that …

Genome-Wide Compensatory Changes Accompany Drug-Selected Mutations In The Plasmodium Falciparum Crt Gene, Hongying Jiang, Jigar J. Patel, Ming Yi, Jianbing Mu, Jinhui Ding, Robert Stephens, Roland A. Cooper, Michael T. Ferdig, Xin-Zhuan Su

Biological Sciences Faculty Publications

Mutations in PfCRT (Plasmodium falciparum chloroquine-resistant transporter), particularly the substitution at amino acid position 76, confer chloroquine (CQ) resistance in P. falciparum. Point mutations in the homolog of the mammalian multidrug resistance gene (pfmdr1) can also modulate the levels of CQ response. Moreover, parasites with the same pfcrt and pfmdr1 alleles exhibit a wide range of drug sensitivity, suggesting that additional genes contribute to levels of CQ resistance (CQR). Reemergence of CQ sensitive parasites after cessation of CQ use indicates that changes in PfCRT are deleterious to the parasite. Some CQR parasites, however, persist in the …

Molecular Characterization And Related Aspects Of The Innate Immune Response In Ticks, Daniel E. Sonenshine, Wayne L. Hynes

Biological Sciences Faculty Publications

Compared to insects, little is known about innate immunity in ticks. This chapter addresses the molecular processes that recognize non-self and the cellular and molecular processes mobilized to phagocytose, engulf, inhibit or kill invaders. We discuss the receptors that recognize pathogen associated molecular patterns (PAMPs) and the putative up-regulation of regulatory cascades that lead, ultimately, to cellular or molecular responses. We describe the molecular events that activate the cellular processes and the array of humoral factors that are mobilized against invading organisms, including antimicrobial peptides, proteases and protease inhibitors, lectins, coagulation factors and others. Special attention is directed to the …

Safety Profile Of Parenteral Ketamine And Lignocaine Infiltration In Pediatric Operations, David O. Osifo, Kennedy N. Emeagui, Sylvester E. Aghahowa

Saudi Medical Journal

OBJECTIVE: To study the safety and benefits of parenteral ketamine and lignocaine infiltration among pediatric surgical patients with co-morbidities that would preclude the use of general anesthesia requiring endotracheal intubation/face mask in a developing country. METHODS: This prospective study was undertaken at the Leadeks Medical Centre, Benin City Edo State, Nigeria between January 2002 and December 2006. Patients requiring surgery were safely operated even in the presence of co-morbidity. RESULTS: A total of 416 children were recruited and they were aged 6 days to 16 years (mean 12 -/+ 2.04 years) with a male/female ratio of 1:1.1. Appendectomy (33.2%), herniotomy …

Glutathione And Malondialdehyde Levels In Patients With Hydatid Cyst, Metin Atambay, Ulku Karaman, Tugba R. Kiran, Cemil Colak, Aysun B. Karabulut, Tuncay Celik, Nilgun Daldal

Saudi Medical Journal

OBJECTIVE: To investigate the levels of glutathione (GSH), and malondialdehide (MDA) in the sera of patients diagnosed with cyst hydatid. METHODS: Forty-six hydatid cyst patients who were indirect hemaglutination (IHA) and indirect fluorescence antibody (IFA) test positive constituted our study group in 2007. Patients diagnosed with hydatid cyst in the Inonu University School of Medicine, Department of Parasitology were re-called for the study. Forty healthy subjects who were negative for hydatid cyst by IHA and IFA methods, and who did not have any parasites on stool inspection formed the control group. The MDA level was analyzed in the sera by …

Saudi Medical Journal

OBJECTIVE: To evaluate the overall incidence of microsatellite instability (MSI), hereditary non polyposis colorectal cancer, and tumor supressor gene (TP53) mutations in Saudi colorectal carcinomas. METHODS: We studied the MSI pathway in Saudi colorectal cancers (CRC) from 179 unselected patients using 2 MSI by polymerase chain reaction, and immunohistochemistry detection of mutL homologs 1 and mutS homologs 2 proteins. The TP53 mutations were studied by sequencing exons 5, 6, 7, and 8. RESULTS: Of the 150 colorectal carcinomas analyzed for MSI, 16% of the tumors showed high level instability (MSI-H), 19.3% had low-level instability (MSI-L) and the remaining 64% tumors …

Can Constitutionalism Be Leftist?, Louis Michael Seiman

Georgetown Law Faculty Publications and Other Works

In this essay, written for a symposium on the work of Mark Tushnet, I examine Tushnet’s effort to defend popular constitutionalism in his powerful and subtle book entitled ATaking the Constitution Away from the Courts,” I ask whether the book succeeds in reconciling constitutionalism with leftism. If there is anyone who could accomplish this task, it is Tushnet. He is without question our most thoughtful constitutional leftist. And yet, the book, at least taken at face value, fails to achieve its goal. To the extent that the book argues for constitutionalism, it abandons leftism, and to the extent it is …

Mixed Speech: When Speech Is Both Private And Governmental, Caroline Mala Corbin

Articles

Speech is generally considered to be either private or governmental, and this dichotomy is embedded in First Amendment jurisprudence. However, speech is often neither purely private nor purely governmental but rather a combination of the two. Nonetheless, the Supreme Court has not yet recognized mixed speech as a distinct category of speech. This Article suggests considerations for identifying mixed speech and exposes the shortcomings of the current approach of classifying all speech as either private or governmental when determining whether viewpoint restrictions pass First Amendment muster. Treating mixed speech as government speech gives short shrift to the free speech interests …

The Teaching And Learning Cycle: Integrating Curriculum, Instruction, And Assessment, Donna L. Jones

Christian Perspectives in Education

The philosophies of educators and government entities guide the teaching and learning cycle of curriculum, instruction, and assessment. The educator’s worldview plays an important part in developing these concepts which is demonstrated throughout history. Studying the history of the educational philosophers reveals their beliefs about curriculum, instruction, and assessments and the effects on education today. It shows the importance of integrating all three concepts in the educational process creating the teaching and learning cycle.

A Picture Of The New York Court Of Appeals At The Time Of Wood V. Lucy, Lady Duff-Gordon, Meredith R. Miller

Scholarly Works

Wood v. Lucy, Lady Duff-Gordon is an enduring part of the Contracts canon. A symposium addressing the legacy of the case would be incomplete without a picture of the New York Court of Appeals at the time the case was decided and a discussion of the oft-neglected role that court rules and administration play in the development of the law. Thus, it is the aim of this short essay to place Wood in the context of the Court's history, and to explore how structural and jurisdictional changes to the Court could have had an impact on how the case was …
