The Photophysics Properties Of Lanthanide Luminescent Probes, Ke Li
The Photophysics Properties Of Lanthanide Luminescent Probes, Ke Li
Theses
A detailed study of the luminescence quantum yield, lifetimes and the number of water molecules coordinated to lanthanide luminescent probes based on biphenylyl-7-amino-4- methyl-2(1H)-quinolinon (Bi-cs124) derivatives have been carried out using a time- resolved fluorescence assay (TRFA). Bi-cs124 was conbined with different chelating agents, specifically diethylene triamine pentaacetic acid (DTPA), ethylene diamine tetraacetic acid (EDTA), ethylene glycol tetraacetic acid (EGTA), and 3,6,9,12-Tetrakis carboxymethyl)-3,6,9,12-tetraazatetradecane-1,14-dioic acid (TTHA). The results indicate that Bi-cs 124-TTHA has a longest lifetime and smallest number of coordinated water molecules because TTHA has larger number of chelating groups. The dependence of the luminescence lifetimes on the probes concentrations …

Formation Of Branching Angles At Bifurcations Of Ant Trail Networks, Subash Kusum Ray
Theses
Ants form dendritic trail networks around the nest to search for and exploit food sources located at the periphery of the network. Studies found these trail networks to be very efficient for the ants in terms of time and energy, which later was found stored in the bifurcation angle (θ) of the branches of these trail networks. It has been observed, that bifurcations are symmetrical when moving from the nest to the food source, while are asymmetrical when moving back towards the nest. The mean bifurcation angles have been found to be 50° - 80° for networks radiating out from …

The Relationship Between Traumagenic Dynamic Responses Towards Childhood Sexual Abuse, Ethnic Identity, Social Support, Trauma Severity, And Attitudes Towards Interpersonal Relationships In Adolescent Females, Nita J. Makhija
Seton Hall University Dissertations and Theses (ETDs)
This study used the theory of traumagenic dynamics (TD) to examine how symptomatology resulting childhood sexual abuse (CSA) are related to the attitudes adolescent females have towards interpersonal relationships. The ultimate goal being that this understanding can inform the creation and implementation of empirically based clinical interventions that specifically target CSA-related symptoms which are associated with the endorsement of unhealthy attitudes towards romantic relationships. In examining this relationship, family support and ethnic identity were examined as protective factors against the endorsement of unhealthy attitudes towards romantic relationships, and trauma severity and the presence of domestic violence in the home were …

Disturbed But Not Destroyed: New Perspectives On Urban Archaeology And Class In 19th Century Lowell, Massachusetts, Katelyn M. Coughlan
Disturbed But Not Destroyed: New Perspectives On Urban Archaeology And Class In 19th Century Lowell, Massachusetts, Katelyn M. Coughlan
Graduate Masters Theses
Through the artifacts from the Jackson Appleton Middlesex Urban Revitalization and Devolvement Project (hereafter JAM) located in Lowell, MA, this research explores social class in nineteenth-century boardinghouses. This thesis is a two-part study. First, through statistical analysis, research recovers interpretable data from urban archaeological contexts subject to disturbance. Pinpointing intra-site similarities between artifacts recovered from intact and disturbed contexts, data show that artifacts recovered from disturbed and intact contexts in urban environments are not as dissimilar as previously believed. In the second phase using both intact and disturbed JAM contexts, the analysis of four boardinghouse features highlights two distinct patterns …
Transcriptional Regulation Of Sinorhizobium Meliloti Cell Cycle-Related Genes In The Δcbra Mutant And Root Nodules Of Medicago Sativa, Corey S. Hazekamp
Transcriptional Regulation Of Sinorhizobium Meliloti Cell Cycle-Related Genes In The Δcbra Mutant And Root Nodules Of Medicago Sativa, Corey S. Hazekamp
Graduate Masters Theses
Sinorhizobium meliloti is a Gram-negative alphaproteobacterium and nitrogen-fixing symbiont, which undergoes a novel cell cycle modification during its' host-microbe interaction. I intend to monitor the transcriptional regulation of cell cycle-related genes during free-loving growth, in addition to monitoring their expression during symbiosis. Using genes known to be regulated by CtrA in C. crescentus or predicted to be regulated by CtrA in S. meliloti, I aim to show how certain cell cycle genes are regulated in S. meliloti. In C. crescentus, CtrA acts as a transcription factor that is active when phosphorylated and inactive when not phosphorylated. In …

Rural-Urban Differences In The Utilization Of Maternal Healthcare In Ghana: The Case Of Antenatal And Delivery Services, Gloria Afful-Mensah, Edward Nketiah-Amponsah, Louis Boakye-Yiadom
African Social Science Review
Although maternal health in Ghana has generally improved over the past two decades, the current MMR implies that Ghana‟s MMR is approximately 2.4 times higher than the set target in MDG 5. Using data from the Ghana Demographic and Health Survey 2008, an attempt is made in this study to investigate the rural-urban differences in maternal health care (antenatal and delivery care) service utilization in Ghana. Most previous studies focused more broadly on the utilization of MHC services either in the entire country or some parts of the country. This study fills the gap by looking at women from the …

Fructose-2,6-Bisphosphate Synthesis By 6-Phosphofructo-2-Kinase/Fructose-2,6-Bisphosphatase 4 (Pfkfb4) Is Required For The Glycolytic Response To Hypoxia And Tumor Growth, Jason Chesney, Jennifer Clark, Alden C. Klarer, Yoannis Imbert-Fernandez, Andrew N. Lane, Sucheta Telang
Markey Cancer Center Faculty Publications
Fructose-2,6-bisphosphate (F2,6BP) is a shunt product of glycolysis that allosterically activates 6-phosphofructo-1-kinase (PFK-1) resulting in increased glucose uptake and glycolytic flux to lactate. The F2,6BP concentration is dictated by four bifunctional 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatases (PFKFB1-4) with distinct kinase:phosphatase activities. PFKFB4 is over-expressed in human cancers, induced by hypoxia and required for survival and growth of several cancer cell lines. Although PFKFB4 appears to be a rational target for anti-neoplastic drug development, it is not clear whether its kinase or phosphatase activity is required for cancer cell survival. In this study, we demonstrate that recombinant human PFKFB4 kinase activity is 4.3-fold greater than …

Pharmaceutical Sciences and Research
The simple and rapid spectrophotometric methods were developed for analysis of hydrocortisone acetate in cream pharmaceutical formulations containing nipagin as preservative. Concentration of hydrocortisone acetate was determined by measuring the first derivative absorption (ratio amplitudes) at 257.0 nm (zero crossing for nipagin). The calibration graphs were linear over the range of 4.0-40.0 ppm of hydrocortisone acetate (r= 0.9999). The limit of detection (LOD) and the limit of quantitation (LOQ) were found to be 0.9617 ppm and 3.2050 ppm, respectively. This method had good precision (repeatability and intermediate precision) with RSD < 2.0% where as the means of the recovery data (accuracy) were 102.03±0.14% and 100.23±0.69% for hydrocortisone acetate cream 1% and 2.5%, respectively. The proposed method was applied for the determination of hydrocortisone acetate in three out of four commercial cream formulations samples and the results of label claim were 102.93±0.22%, 108.48±0.19% and 106.67±0.35% for sample A, B and D, respectively. The result of brand C analysis showed to contain more than 110.0% of the labeled amount of hydrocortisone acetate, indicated there was additive other than nipagin in the cream basis to interfer with the hydrocortisone acetate measurements.
