Objective: This study aimed to fabricate and characterize a novel periodontal barrier nanofibers-based bio-membrane using electrospinning.
Materials and Methods: The matrix solution was prepared from poly (vinyl alcohol) (PVA) incorporating hydroxyapatite, hyaluronic acid, collagen, L-arginine and vanillin to fabricate composite membrane. Subsequently the elemental analysis, viscosity, conductivity and surface tension of solutions before spinning were evaluated. The physicochemical and mechanical properties were characterized using UV-VIS spectroscopy, scan electron microscope (SEM), fourier transform infrared spectroscopy (FT-IR) and tensile strength. Data were expressed as mean and standard deviation (±SD). P values < 0.05 were considered significant.
Results: The results revealed that the composite solution surface tension …

How Stromal Interactions Play A Role In The Quest For Human Papillomavirus Specific Cancer Therapeutics, Alexis-Leigh A. Fakunmoju
Theses and Dissertations
High-risk human papillomaviruses (HPV), like HPV16 and HPV18, are associated with malignant cancer growth within the oropharynx and cervix. Globally, HPV-induced cancers, including oropharyngeal and cervical cancers, contribute 5% to the overwhelming burden of all cancers. HPV is highly transmissible by sexual contact via micro abrasions to the mucosa. Once exposure occurs, the virus begins replication and creates an intimate relationship with the host’s cellular proteins. While most HPV is cleared quickly by our immune system, persistent infections, or infections in immune compromised individuals, are susceptible to transformation and tumor progression. Early detection measures like PAP smears and preventable measures …

This in vitro study aimed to investigate the effect of different chromium metal alloys on enamel wear through longitudinal observation across various simulated chewing cycles. Four groups of alloys were studied (n=10 per group): casting Ni-Cr alloys (NC), casting Co-Cr alloys (CC), SLM Co-Cr alloys (CS), and heat-treated SLM Co-Cr alloys (CS-H). The test simulated chewing of enamel cusps against the alloys in distilled water under specific conditions (49 N load, 0.7 mm sliding movement, and 1.6 Hz frequency). Enamel wear was measured at 60,000, 120,000, and 240,000 cycles by using intraoral scanner matching with open-source 3D software. Enamel wear …

Faculty, Staff and Student Publications
Periodontitis is a chronic inflammatory disease induced by dysbiotic dental biofilms. Management of periodontitis is primarily anti-bacterial via mechanical removal of bacterial biofilm. The successful resolution requires wound healing and tissue regeneration, which are not always achieved with these traditional methods. The discovery of specialized pro-resolving mediators (SPMs), a class of lipid mediators that induce the resolution of inflammation and promote local tissue homeostasis, creates another option for the treatment of periodontitis and other diseases of chronic inflammation. In this mini-review, we discuss the host-modulatory effects of SPMs on periodontal tissues and changes in the taxonomic composition of the gut …

Melanomas are outstandingly aggressive cancers, still their incidence is increasing. They can occur in the skin as cutaneous melanoma or in the eye as ocular melanoma. Their pathogenesis is generally similar; however, the prognosis of ocular melanoma patients is still poor, due to its special genetic profile and tumor microenvironment. Here we review the similarities and differences between cutaneous and ocular melanoma, with a focus on their prognostic significance, their molecular signature, and their tumor microenvironment, in order to understand the strategies adopted to escape immune response. Gathering and understanding available knowledge of melanomas and their specificities may help to …
