Oral Cancer Awareness Among University Students From Karachi, Pakistan, Dnyanesh Limaye, Patrick Ziesenis, Vaidehi Limaye, Mansoor Ahmad, Farah Saeed, Mahboob Alam, Ramla Rizvi, Atul Kapadi, Sushama Sathe, Gerhard Fortwengel

Section of Dental-Oral Maxillofacial Surgery

Background: Oral cancers (OC) are malignant lesions occurring in the oral cavity that include squamous cell carcinomas (SCC), salivary gland and odontogenic neoplasms. Even though it is the eighth most common malignancy globally but in Pakistan it is the second commonest type of cancer. Lack of awareness about ill-effects of preventable risk factors of oral cancer increases the burden of disease due to the associated high cost of treatment, permanent impairment and high mortality. Hence, awareness can be very helpful in prevention, control and early diagnosis of oral cancer.
Methods: A cross-sectional study was carried out among university students from …

Association Between Periodontal Pathogens And Systemic Disease, Fiona Q. Bui, Cássio Luiz Coutinho Almeida-Da-Silva, Brandon Huynh, Alston Trinh, Jessica Liu, Jacob Woodward, Homer Asadi, David M. Ojcius

All Dugoni School of Dentistry Faculty Articles

A growing body of literature suggests that there is a link between periodontitis and systemic diseases. These diseases include cardiovascular disease, gastrointestinal and colorectal cancer, diabetes and insulin resistance, and Alzheimer's disease, as well as respiratory tract infection and adverse pregnancy outcomes. The presence of periodontal pathogens and their metabolic by-products in the mouth may in fact modulate the immune response beyond the oral cavity, thus promoting the development of systemic conditions. A cause-and-effect relationship has not been established yet for most of the diseases, and the mediators of the association are still being identified. A better understanding of the …

School of Dentistry Faculty Research and Publications

Oxygen plays a key role in human mesenchymal stem cell growth. Without adequate oxygen (hypoxic condition), cells are not able to survive, proliferate, and migrate. The objective of the present study is to investigate oxygen transfer through the cell-seeded scaffolds stored in static or dynamic bioreactors using a mathematical model. The effects of porosity, cell type, scaffold architecture and cell distribution as potential effective parameters on oxygen transfer kinetics were examined. The results suggest the substantial effect of porosity and cell type on the oxygen concentration within the scaffold compared to scaffold architecture (homogeneous vs. gradient). The obtained data …

Microfluidic Synthesis Of Plga/Carbon Quantum Dot Microspheres For Vascular Endothelial Growth Factor Delivery, Meisam Omidi, Mohadeseh Hashemi, Lobat Tayebi

School of Dentistry Faculty Research and Publications

In this study, vascular endothelial growth factor (VEGF) loaded poly(D,L-lactide-co-glycolide) (PLGA) – carbon quantum dot microspheres were produced using microfluidic platforms. The microcapsules were fabricated in flow-focusing geometry with a biphasic flow to generate solid/oil/water (s–o–w) droplets. To avoid any damage to protein functional and structural stability during the encapsulation process, the VEGF was PEGylated. The produced microspheres were intact and highly monodisperse in size (CV < 5%). Furthermore, microspheres in a size range of 16–36 µm were achieved by adjusting the flow ratio parameter. The encapsulation efficiency, release profile, and bioactivity of the produced microparticles were also studied. The loading efficiency of PEGylated VEGF in the microparticles was varied from 51–69% and more than 90% of PEGylated VEGF was released within 28 days. Furthermore, the release of VEGF was indirectly monitored by carbon quantum dots. The present monodisperse and controllable VEGF loaded microspheres with reproducible manner could be widely used in tissue engineering and therapeutic applications.

Designing Biomimetic Implant Surfaces To Promote Osseointegration Under Osteoporotic Conditions By Revitalizing Mechanisms Coupling Bone Resorption To Formation, Ethan M. Lotz

Theses and Dissertations

In cases of compromised bone remodeling like osteoporosis, insufficient osseointegration occurs and results in implant failure. Implant retention relies on proper secondary fixation, which is developed during bone remodeling. This process is disrupted in metastatic bone diseases like osteoporosis. Osteoporosis is characterized low bone mass and bone strength resulting from either accelerated osteoclast-mediated bone resorption or impaired osteoblast-mediated bone formation. These two processes are not independent phenomena. In fact, osteoporosis can be viewed as a breakdown of the cellular communication connecting bone resorption to bone formation. Because bone remodeling occurs at temporally generated specific anatomical sites and at different times, …
