Evaluating cardiac gene expression in maternal phenylketonuria offspring

McCoy, Jennifer Ellie (2006-05)

Maternal phenylketonuria (MPKU) is a teratogenic syndrome, caused by development of offspring in a uterine environment made toxic by the metabolic imbalance of PKU. The birth defects resulting from untreated MPKU include ...
Reassessment of intra- and extra-ovarian expression of growth differentiation factor-9

Bowser, Jessica Lynn (2006-05)

Mammalian ovarian organogenesis is characterized temporally by oogonial mitosis, oogonial apoptosis, rescue of germ cells via interaction with somatic cells to form primordial follicles, and entrance into meiosis. Recent ...
West Nile virus and wild bird populations

Shelite, Thomas R. (Wichita State University, 2006-05)

West Nile Virus (WNV) first appeared in the western hemisphere in 1999, and has since spread across the United States and into Mexico and the Caribbean. It has been hypothesized that WNV has spread rapidly via migratory ...
The effect of large neutral amino acids on maternal phenylketonuria offspring

Gowda, Supriya Srinivasa (Wichita State University, 2006-05)

Women with untreated phenylketonuria (PKU), tend to give birth to infants with multiple congenital anomalies, as elevated maternal phenylalanine (Phe) level is teratogenic. The best outcomes occur when strict control of ...
Soil community analysis along a salt gradient using denaturing gradient gel electrophoresis of PCR-amplified 16s rRNA genes

Dutta, Partha (2006-05)

Many studies of hyper saline environments have been performed, mainly on aquatic systems. However, the microbial community in terrestrial thallasohaline environments has not been studied extensively. To our knowledge, this ...
GCNF as a growth regulator in normal and neoplastic cells

Srikanthan, Sowmya (2007-05)

Germ cell nuclear factor (GCNF/NCNF/RTR, NR6A1) is an orphan member of the nuclear receptor super family that exhibits repressive transcriptional activity and is expressed in the embryonic stem cells, embryonic carcinoma ...
Abundance of nifH genes in urban, agricultural, and pristine prairie streams exposed to different levels of nitrogen loading

Santos-Caton, Ingrid R. (2007-05)

Ecosystem processes drive biogeochemical cycles that influence input and losses of nutrients in the biosphere. Through human activities the environment has been highly enriched with nutrients, especially nitrogen. In most ...
Mechanism of ovarian disruption by neonatal DES exposure: A further investigation into ovarian function in the hamster cheek pouch

Alwis, Imala D. (Wichita State University, 2007-07)

Treatment of hamsters on the day of birth with the synthetic estrogen and prototypical endocrine disruptor, diethylstilbestrol (DES), induces severe anomalies throughout the female reproductive tract. The disruption ...
Analysis of aggregation behavior of Xenopus Laevis tadpoles in relation to sibling rearing condition and presence of a predator cue

Brane, Kate Elizabeth (Wichita State University, 2008-08)

Differential effects on behavior of a focal tadpole subjected either to the absence or presence of a predator cue were examined when the focal animal was in the presence of conspecific tadpoles differing in relatedness and ...
Follicle stimulating hormone-receptor expression in the aging human ovary

Asthi, Karthik (Wichita State University, 2008-12)

The follicles in a human ovary gradually decline in number during infancy, adolescence and the reproductive years. However, during the perimenopausal period there is a more rapid decline in follicles. Older women have fewer ...
Effects of atrazine, chlorpyrifos, and their interactions on anti-predator behavior and activity in African clawed frogs, Xenopus laevis

Heckmann, Jonathan Gardner (Wichita State University, 2009-05)

Two separate experiments were conducted to examine potential mixture effects of chronic, sub-lethal concentrations of atrazine and chlorpyrifos on the alarm response and activity of larva of the African clawed frog, Xenopus ...
Causes of variation in damage by folivores: The roles of ecosystem productivity and habitat complexity

Shrestha, Shubha (Wichita State University, 2009-05)

Understanding the causes of variation in herbivore damage among individual plants is important because it may lead to strategies for increasing damage to invasive weeds, thereby, reducing their population growth. My ...
Human follicle-stimulating hormone glycoform abundance during the normal menstrual cycle in women

Rueda Santos, Monica A. (Wichita State University, 2009-05)

Human FSH exists as two major glycoforms, tetra-glycosylated and di-glycosylated hFSH. Tetra-glycosylated FSH possesses both α and β subunit carbohydrates while di-glycosylated hFSH possesses only α subunit carbohydrates. ...
The role of altered microRNA expression in an experimental model of estrogen-dependent uterine cancer

Padmanabhan, Ramesh (Wichita State University, 2009-07)

This project screened for altered expression of small RNA species, microRNAs (miRNA), in the hamster uterus following neonatal exposure to the potent synthetic estrogen and established endocrine disruptor diethylstilbestrol ...
Developmental expression of GCNF during organ maturity

Rogers, Andrea Michelle (Wichita State University, 2010-05)

Without a ligand, Germ Cell Nuclear Factor (GCNF) binds to and represses genes. Targets include Oct4 (involved in the pluripotency of embryonic and germ cells), CRIPTO-1 (found in undifferentiated stem cells), and reproductive ...
Expression of a novel follicle stimulating hormone glycoform

Tran, Thao P. (Wichita State University, 2010-05)

Heterodimeric pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), play significant roles in follicular development and maintenance of the female reproductive cycle. FSH functions in ...
Indirect, plant mediated interactions of meristem miners on flower head feeders, a case for non-independence?

Jones, Matthew D. (Wichita State University, 2010-05)

A long standing, dominant paradigm in the biological control of weeds is the independence of insect herbivore guilds' effects on their host plant. Recent work has shown stronger interactions among insect herbivore guilds ...
Differential expression of germ cell nuclear factor (GCNF) in human ovarian cancer cell lines

Devabhakthuni, Rajeswari (Wichita State University, 2010-05)

Germ Cell Nuclear Factor (GCNF) is the only existing member of nuclear receptor (NR) super family NR6A1, and an orphan receptor because of an unidentified ligand. Members of NR superfamily act as ligand activated ...
Molecular interactions between the pathogenic fungus Macrophomina phaseolina and its plant host Medicago truncatula

Reyes Gaige, Andres (Wichita State University, 2010-08)

Macrophomina phaseolina is a necrotrophic soil-borne fungal pathogen that causes a disease commonly known as charcoal rot. This fungus has the potential to infect over 500 different plant species worldwide including many ...
Does productivity matter? An investigation of habitat use by insect and small mammal herbivores in a grassland system

Samant, Suvidha S. (Wichita State University, 2011-05)

Although some ecological theory predicts that herbivore density should increase with plant quality or biomass, few studies have directly measured the response of multiple groups of grassland herbivores to changes in plant ...
