Chemical Composition And Behavioural Responses Of Male And Female Bactrocera Dorsalis To Their Volatile Emissions, Fikira Kimbokota

Journal of Humanities and Social Sciences

Bactrocera dorsalis, (Tephritidae) presented a grave threat to a broad range of fruit and vegetables in the tropics, including Tanzania. Bactrocera dorsalis is among the most destructive tephritid fruit fly, causing devastating loss of fruits especially mango. Insects use olfactory cues to locate hosts, oviposition sites and mating, in which pheromones are believed to be a strong cue used by insect to locate their mates. However, due to their high ability to adapt and occupy different ecological niches into various agroecological zones, there is a need to evaluate pheromonal composition from time to time to improve their control strategies. Therefore, …

Amphiphilic Cell-Penetrating Hybrid Cyclic-Linear Peptides As A Drug Delivery System, Saghar Mozaffari

Pharmaceutical Sciences (PhD) Dissertations

A number of cyclic peptides containing a positively charged ring composed of arginine residues attached to hydrophobic tail made of tryptophan residues through a lysine linker namely [R₅K]W₅, [R₆K]W₅, [R₅K]W₆, [R₇K]W₅, [R₅K]W₇, [R₆K]W₆, and [R₇K]W₇ were synthesized and evaluated as molecular transporters. The peptides were evaluated for their ability to deliver, fluorescence-labeled cell-impermeable negatively charged phosphopeptide (F′-GpYEEI), and fluorescent labeled anti-HIV drugs (F′-FTC and F′-d4T). The results indicated that the presence of positively …

Chlorhexidine Gluconate Vs Povidone-Iodine In The Prevention Of Clean-Contaminated Surgical Site Infections, Erin Layne, Abigail Stone

Physician Assistant Capstones, 2016 to 2019

Abstract

Background:

A patient’s skin is the major source of pathogens that can cause post-operative complications such as surgical site infections (SSIs). Optimization of pre-operative skin antisepsis is obtained with chlorhexidine gluconate (CG) and povidone-iodine (PI). These two solutions are the most widely used antiseptics for pre-operative purposes.

Objective:

Among surgical patients greater than 18 years of age undergoing clean-contaminated surgery, which antiseptic, iodophors or chlorhexidine gluconate, is more effective at reducing postoperative surgical site infections?

Methods:

A search was done in PubMed utilizing the terms chlorhexidine, infection control, iodophors, and surgical site infection. The limits applied included randomized …

Budesonide Enhances Agonist-Induced Bronchodilation In Human Small Airways By Increasing Camp Production In Airway Smooth Muscle, Cynthia J. Koziol-White, Timothy B. Johnstone, Maia L. Corpuz, Gaoyuan Cao, Sarah Orfanos, Vishal Parikh, Brian Deeney, Omar Tliba, Rennolds S. Ostrom, Ian Dainty, Reynold A. Panettieri Jr.

The non-genomic mechanisms by which glucocorticoids modulate β₂ agonist-induced-bronchodilation remain elusive. Our studies aimed to elucidate mechanisms mediating the beneficial effects of glucocorticoids on agonist-induced bronchodilation. Utilizing human precision cut lung slices (hPCLS), we measured bronchodilation to formoterol, prostaglandin E₂ (PGE₂), cholera toxin (CTX) or forskolin in the presence and absence of budesonide. Using cultured human airway smooth muscle (HASM), intracellular cAMP was measured in live cells following exposure to formoterol, PGE₂, or forskolin in the presence or absence of budesonide. We showed that simultaneous budesonide administration amplified formoterol-induced bronchodilation and attenuated agonist-induced phosphorylation …

Substituted Anthraquinones Represent A Potential Scaffold For Dna Methyltransferase 1-Specific Inhibitors, Rebecca L. Switzer, Jessica Medrano, David A. Reedel, Jill Weiss

Faculty Journal Articles

In humans, the most common epigenetic DNA modification is methylation of the 5-carbon of cytosines, predominantly in CpG dinucleotides. DNA methylation is an important epigenetic mark associated with gene repression. Disruption of the normal DNA methylation pattern is known to play a role in the initiation and progression of many cancers. DNA methyltransferase 1 (DNMT1), the most abundant DNA methyltransferase in humans, is primarily responsible for maintenance of the DNA methylation pattern and is considered an important cancer drug target. Recently, laccaic acid A (LCA), a highly substituted anthraquinone natural product, was identified as a direct, DNA-competitive inhibitor of DNMT1. …

Understanding Structure-Activity Relationship Of Synthetic Cathinones (Bath Salts) Utilizing Methylphenidate, Barkha J. Yadav

Theses and Dissertations

Synthetic cathinones are stimulant drugs of abuse that act at monoamine transporters e.g. the dopamine transporter (DAT) as releasing agents or as reuptake inhibitors. More than >150 new synthetic cathinones have emerged on the clandestine market and have attracted considerable attention from the medical and law enforcement communities.

threo-Methylphenidate (tMP) is an FDA approved drug for the treatment of ADHD and narcolepsy, which also acts as a DAT reuptake inhibitor and is widely abused. tMP and synthetic cathinones share some structural similarities and extensive structure-activity relationship (SAR) studies on tMP have been conducted. However, much less is known about the …
