The results showed that the sorption of explosive to black hair is significantly higher than brown, blond and bleached hair. The hair did not …

What's Wrong And Who Cares? Reader Reaction To Error, Susan Rashid Horn

Open Access Dissertations

As much as readers profess to be bothered by its presence, little is known about error except that it is irksome. This study demonstrates that error has practical consequences. While error may not significantly affect reading comprehension, it does affect reading time and reading patterns, and its presence correlates with a negative construction of the writer. Prior studies about error have been conducted in formats where errors are highlighted and readers are queried about the degree of "bothersomeness." But Williams has demonstrated there is a difference between reading for error and reading for content. So in this study, errors were …

Effects Of Endocrine-Disrupting Chemicals On Fish Reproduction And Reproductive Indicators, Lesley Judith Mills

Open Access Dissertations

The central hypothesis tested in this dissertation is that endocrine-disrupting chemicals (EDCs) found in the aquatic environment disrupt reproductive processes in fish. To gain a broad perspective of existing evidence, a review of the current literature was conducted. From this literature review, the lack of a dependable method or indicator to assess reproductive fitness of fish in situ was identified as an outstanding need. In laboratory experiments, reproductive endpoints (egg production, fertility and viablity) were measured in the marine fish Tautogolabrus adspersus , or cunner, implanted with estrogens. Estrone and ethynylestradiol significantly reduced egg production in treated cunner at the …

Synthesis Of Some Pyridinone Nucleoside Analogues As Antitumor Agents, Shaikha Saif Saeed Alneyadi

Theses

Abstract

3-Deazapyrimidine nucleosides have been shown to exhibit great potential as pro drug for use in medicine especially as antagonists to cancer tumors and the HIV-virus. Recent research has focused on the design, synthesis and characterization of novel nucleoside analogues.

Fluoropyridinone and their corresponding nucleoside derivatives have been synthesized and characterized to induce the activity against tumors. 4, 6-diaryl-3-cyano-2(1H)-pyridinones (82a-i) and their nucleosides were prepared. A trifluoromethyl group was introduced into the pyridinone ring system to study its effect on different tumor cells. The glycoside analogues (83a-e, 85a-e, 87a-e and 88a-d) have been synthesized …

Development Of Electroanalytical Methods For The Determination Of Sialic Acid As A Biomarker For Cancer, Khawla Ali Rashid Al-Tayyari

Theses

Sialic acid (SA) is a general term for a family composed of 43 derivatives of neuraminic acid. Whereas N-acetylneuraminic acid (NANA) is the most commonly occurring sialic acid in human. There has been a great interest in the determination of SA in humans because variations in SA level was linked to different medical conditions and diseases. In particular, serum SA are elevated in several types of cancers. SA also exists in Erythropoietin (EPO), a hormone, which induces the production of red blood cells and hence used in the treatment of anemia.

Although of the great physiological significance of SA …

Effects Of Novel Synthetic Nucleosides As Anti-Tumor Agents On Human Acute Promyelocytic Leukemia Cell Line (Hl-60), Salma Awad Merghani Mahmoud

Theses

Nucleosides and their analogs are considered a clinically proven class of therapeutic agents possessing anticancer and antiviral activity. Several trifluoromethyl-substituted pyrazole N-nucleosides (coded NIA, NIIA and NIIA) and their nucleobases were synthesized and tested for the ability to induce apoptosis in acute human promyelocytic cell line (HL-60). The growth and proliferation of HL-60 was more effectively inhibited by NIA, NIIA and their nucleobases compared to NIIIA and its nucleobase. In addition, DNA fragmentation was detected in a concentration-dependent manner as a result of nucleosides treatment. A caspase-3-dependent apoptosis was observed based on the Western blot analysis of poly-ADP-ribose polymerase (PARP) …

Expression Of Tumor Suppressor Genes During Breast Cancer Progression In The Rat, Wafa Saqer Rashid Abdullah Aldhaheri

Theses

Breast cancer is the most common type of cancer and the leading cause of cancer deaths among women in the United Arab Emirates and all over the world. Although many factors contribute to the high incidence of breast cancer, a considerable number of cases are related to environmental factors. In this study, breast cancer was induced in female rats using a single dose, 80 mg/kg body wt, of the environmental carcinogen 7,12- dimethylbenz[a]anthracene (DMBA). The aim was to characterize some of the early cellular and molecular changes that occur during breast cancer development in the DMBA-treated rat model. Mammary gland …

Effects Of Medicinal Plants On Lead Induced Toxicity Of Biotransformation And Redox Cycling Enzymes, Yusra Saif Khalfan Al Dhaheri
