Digital Holographic Microscopy Of Phase Separation In Multicomponent Lipid Membranes, Vahideh Farzam Rad, Ali-Reza Moradi, Ahmad Darudi, Lobat Tayebi

School of Dentistry Faculty Research and Publications

Lateral in-homogeneities in lipid compositions cause microdomains formation and change in the physical properties of biological membranes. With the presence of cholesterol and mixed species of lipids, phospholipid membranes segregate into lateral domains of liquid-ordered and liquid-disordered phases. Coupling of two-dimensional intralayer phase separations and interlayer liquid-crystalline ordering in multicomponent membranes has been previously demonstrated. By the use of digital holographic microscopy (DHMicroscopy), we quantitatively analyzed the volumetric dynamical behavior of such membranes. The specimens are lipid mixtures composed of sphingomyelin, cholesterol, and unsaturated phospholipid, 1,2-dioleoyl-sn-glycero-3-phosphocholine. DHMicroscopy in a transmission mode is an effective tool for quantitative visualization of phase …

The Effects Of Orthodontic Appliance Base Plate Material, Pmma, Infused With Silver And A Novel Antibacterial Compound On Biofilm Formation, Ryan D. Jolley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Retention is required in the majority of orthodontic patients throughout the remainder of their life. The traditional Hawley style retainer is still considered by many orthodontic professionals to be the gold standard in retention appliances. The orthodontic population, in general, is at a higher risk for caries due to plaque accumulation from poor diet, suboptimal oral hygiene, and often a lack of motivation. A Hawley retainer that reduces caries-causing oral microbes could improve oral health and be very beneficial to the post-orthodontic patient. Developing methods to safely include antibacterial products within the Hawley retainer’s base plate material could help effect …

Intercanine Distance Used As A Measure To Rule Out Biters In Bite Mark Forensics, Alana Joy Scudiere Ohana

Masters Theses

The science of identification by bite mark analysis has recently been called into serious question. (Reesu and Brown 2016) Human dentition is truly variable, but often not unique. When animal bites are considered, a proper ID of the perpetrator is nearly impossible. Primary distortion (when the bite is made) and secondary distortion (during decomposition or healing) both further disrupt landmarks that might be used for identification. (Sheasby and MacDonald 2001) Using only ink marks and intercanine distance on live subjects, this study attempts to determine maximum distortion possible for a variety of bite mark locations on skin. (Pretty and Sweet …

Oral Microbial Burden Of Periodontal Pathogens Among Orthodontic Patients, David Jolley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objectives

Many research studies involving orthodontic patients have a natural inclination to focus on changes in levels of cariogenic pathogens after bracket placement, and very few studies examine the role of changes of periodontal pathogens – particularly among adult patients. Interestingly, recent evidence suggests that increased levels of a specific periodontal pathogen, Fusobacterium nucleatum, may elevate risk for development of colon cancer in adults through direct pathways. Based upon this new evidence, the objective of the current study was to screen saliva samples taken from orthodontic patients to determine the prevalence of periodontal pathogens, including F. Nucleatum, T. denticola, and …

Mechanism Of Interaction Of Peptide Modified Nanoparticles With Porphyromonas Gingivalis., Ankita Jain

Electronic Theses and Dissertations

Studies suggest that P. gingivalis functions as a keystone pathogen and interacts with primary colonizers in the supragingival biofilm such as S. gordonii. This interaction contributes to the initial colonization of the oral cavity by P. gingivalis and thus represents a potential target for therapeutic intervention. We have identified a peptide (BAR) derived from the streptococcal SspB protein that functions to inhibit P. gingivalis adherence to S. gordonii. In addition, we showed that nanoparticles (NPs) functionalized with BAR inhibit this interaction more potently than free soluble peptide, possibly by promoting interaction with P. gingivalis at higher valency than …

Role Of Lipid Mediators In P2x7 Signaling In Osteoblasts, Erin Eyer

Electronic Thesis and Dissertation Repository

P2X7 is a cell-surface nucleotide receptor that plays a critical role in skeletal mechanotransduction; however, the signaling pathways mediating these effects are poorly understood. Previous studies showed that the nucleotide analog benzoylbenzoyl-ATP induces anabolic gene expression in osteoblastic cells. Our first objective was to determine whether this effect was mediated by P2X7. Inhibition of anabolic gene expression by a P2X7-specific antagonist established involvement of this receptor. Our second objective was to investigate the role of lipid mediators, lysophosphatidic acid (LPA) and prostaglandin (PG), both of which are produced in response to P2X7 activation. The effect of P2X7 on expression of …

One of the dental psychosomatic territories is the link between personality traits and oral health treatment. This present study aims at investigating whether determination of patient personality types leads to enhanced communication between dental hygienists and patients resulting in improved oral health. Some hypothesize that determining patient personality traits results in enhanced communication between the patient and the dental hygienist. Similarly, it is hypothesized that determination of a patient’s personality trait can result in better oral health.

Nasal Morphology As A Predictor Of Craniofacial Growth Direction, Christos Papadopoulos

Electronic Thesis and Dissertation Repository

It is important for an orthodontist to predict growth related changes and thereby appropriately time orthodontic treatment using the vertical indicators currently available. A potential predictor of craniofacial growth direction that has been discussed yet remains scientifically unexplored is nasal morphology. The objectives of this study are to determine if a difference in pre-adolescent nasal contour exists between post-adolescent normodivergent and hyperdivergent subjects, and if nasal contour morphology in pre-adolescent females is a reliable indicator of future craniofacial growth direction. A significant difference in pre-adolescent nasal contour morphology was found between normodivergent and hyperdivergent groups. A pre-adolescent nasal contour elevation …
