Pituitary tumor transforming gene ( PTTG ), also known as securing, is a novel oncogene that is expressed at high levels in most of the tumors analyzed to date. Overexpression of PTTG in mouse fibroblast(NIH 3T3) cells increases cell proliferation,...
This dissertation is a hypothesis-driven research oriented study to determine the role of the pituitary-tumor transforming gene (PTTG) in ovarian cancer, specifically if it is involved in neoplastic transformation leading to tumorigenesis through...
Cancer patients show circadian disruption that increases as disease progresses. Disrupted endocrine and activity rhythms predict early metastatic cancer mortality. Effects of psychological versus biological factors on rhythms are unknown, as are...
The mechanisms by which estrogens regulate mitochondrial activity are not completely understood. Chronic treatment of ovariectomized rats with estradiol (E 2 ) increased the amount of Nuclear Respiratory Factor-1 (NRF-1) protein in cerebral blood...
Among gynecological malignancies, carcinoma of the cervix is the leading cancer type worldwide. Conversely, vaginal tumors account for an incidence of approximately 1-2% of lower genital tract malignancies. Interestingly, the major shared risk...
BACKGROUND: Regulated secretion of protein by salivary and other exocrine glands requires correct trafficking of soluble cargo proteins into secretory vesicles. However, the molecular mechanism of sorting in the parotid salivary gland is unknown....
Tobacco smoke is a strong and independent risk factor for several chronic systemic diseases and also increases susceptibility to a multitude of bacterial infections, including periodontal infections. Periodontitis is a chronic inflammatory disease...
Chronic periodontitis is strongly associated with composition of the oral biofilm
occupying the gingival crevicular aspect of the tooth and its associated root. Some gram-negative,
"red complex" bacteria instigate periodontal bone loss in...
Gene therapy; Spinal cord--Wounds and injuries; Tissue engineering
The combination of viral mediated gene delivery, tissue engineering, and Schwann cell (SC) transplantation offer a promising strategy to enhance axonal regeneration and functional recovery following spinal cord injury (SCI). The rationale and...
Polycyclic aromatic hydrocarbons; Fetus--Effect of tobacco on
Polycyclic aromatic hydrocarbons (PAH) are chemicals generated from the incomplete combustion of organic materials, including tobacco smoke. Some PAH are known to be mutagenic and carcinogenic in humans, and of concern for the fetus when women...
Human adult olfactory epithelium contains neural progenitors (hONPs) which replace damaged cellular components throughout life. Methods to isolate and expand the hONPs have been developed in our laboratory. In response to morphogens, the hONPs...
Computer-assisted instruction; Three-dimensional imaging; Neuroanatomy--Study and teaching (Higher)
Visualizations in the form of computer-based learning environments are highly
encouraged in science education, especially for teaching spatial material. Some spatial
material, such as sectional neuroanatomy, is very challenging to learn. It...
Introduction: The study investigated dimensional relationships between the sphenoid and maxillary sinuses and other selected craniomaxillofacial structures by using traditional cephalometric and volumetric procedures based on cone beam computed...
Human arylamine N-acetyltransferase (NAT) is a phase II cytosolic enzyme that occurs as two isozymes, NAT1 and NAT2. This family of polymorphic enzymes catalyzes the detoxification and/or activation of many aromatic and heterocyclic amine drugs and...
Research over the past twenty five years has led to the development of the hypothesis that colorectal cancer is caused by the accumulation of mutations in tumor suppressor genes and proto-oncogenes. The last ten years has also revealed that the...
Purpose: To evaluate baseline and 3 different image enhancements for the detection of landmarks and overall perceived quality in photostimuable phosphor cephalograms. Methods: DenOptix images of 48 patients (plus 12 repeats) were presented randomly...
Dehydroepiandrosterone (DHEA) is a C-19 adrenal steroid and the most abundant circulating hormone in humans. Since circulating levels decline in late adulthood, treatment of humans with DHEA has been suggested to have beneficial health effects....
Obesity in children; Obesity in adolescence; Orthodontics
The purpose of this study was to determine if obesity impacts craniofacial dimensions in adolescent and teenage subjects. Twenty-one cephalometric measurements were selected as a basis for comparison between normal weight, overweight and obese...
20S proteasome, essential component of protein degradation mechanism, is important to maintain homeostasis. Its malfunctions have been associated with several pathological conditions. This study presents an extensive study of murine cardiac 20S...
