Oral Health Is Important, But How Important?, Alexander G. Dengel

Population Health Research Brief Series

Dental care is often overlooked as a priority and sometimes considered more of a chore rather than an important aspect of personal health. This oversight can lead to poor health outcomes like gingivitis, periodontitis, and even chronic illness like heart disease, diabetes, and cancer. This issue brief describes the short- and long-term effects of a poor dental health routine and the simple steps necessary to maintain a healthy smile.

Total Salivary Protein Concentration And Its Correlation To Dental Caries, Emyli Peralta, Jonathan Joseph

The Pegasus Review: UCF Undergraduate Research Journal

According to the World Health Organization, dental cavities are the number one chronic disease in children. Saliva coats the teeth all day and serves many functions to maintain and protect teeth. Saliva has many proteins that can be both detrimental and essential to the preservation of tooth enamel. The purpose of this study was to determine if a correlation exists between the total protein concentration in saliva and the prevalence of cavities in the mouth. We hypothesized that there would be a positive correlation between total salivary protein concentration and the prevalence of cavities in the participant.Saliva samples were collected …

Phenytoin Inhibits Cell Proliferation Through Microrna-196a-5p In Mouse Lip Mesenchymal Cells, Hiroki Yoshioka, Sai Shankar Ramakrishnan, Akiko Suzuki, Junichi Iwata

Faculty, Staff and Student Publications

Cleft lip (CL) is one of the most common birth defects. It is caused by either genetic mutations or environmental factors. Recent studies suggest that environmental factors influence the expression of noncoding RNAs [e.g., microRNA (miRNA)], which can regulate the expression of genes crucial for cellular functions. In this study, we examined which miRNAs are associated with CL. Among 10 candidate miRNAs (miR-98-3p, miR-101a-3p, miR-101b-3p, miR-141-3p, miR-144-3p, miR-181a-5p, miR-196a-5p, miR-196b-5p, miR-200a-3p, and miR-710) identified through our bioinformatic analysis of CL-associated genes, overexpression of miR-181a-5p, miR-196a-5p, miR-196b-5p, and miR-710 inhibited cell proliferation through suppression of genes associated with CL in cultured …

Mccormack, Daniel Contaifer, Naren Gajenthra Kumar, Saidheeraj Paravataneni, Monther Alsultan, Suad Alshammari, Silas Contaifer, Parthasarathy Madurantakam, Dayanjan Wijesinghe

Pharmacotherapy and Outcomes Science Publications

Aims: Platelet rich plasma (PRP) has been used in tissue repair to treat numerous inflammatory pathophysiologies. Recent studies have elucidated that the bioactive lipid fraction of PRP significantly contributes towards the resolution of inflammation. There has been great interest in how therapeutics could modulate the PRP lipidome to formulate a more pro-resolving matrix. Many of the pathways used to produce either pro-resolving or pro-inflammatory lipids are shared between ω-3 and ω-6 polyunsaturated fatty acids (PUFA). Here, we explored the separate and interacting effects acute exogenous ω-3 PUFA supplementation and aspirin had on the lipidome of PRP within 6 hours.
