School of Dentistry Faculty Research and Publications

Background

Syphilis is a sexually-transmitted infectious disease caused by Treponema pallidum. Cases of primary and secondary syphilis are on the rise in the United States, with a 14.4% increase in new cases noted from 2017 to 2018 and an escalation of 71% between the years 2014 and 2018. Fulfilling its nickname of “the great imitator,” oral manifestations of syphilis may mimic a variety of infectious, neoplastic, or immune-mediated processes, both clinically and histopathologically. This large spectrum of appearances can create a diagnostic challenge to the clinician and/or pathologist, leading to delay in diagnosis or misdiagnosis.

Inventing Dental Continuing Education: History Of The Dental Forum -- Milwaukee, Kenneth J. Waliszewski

School of Dentistry Faculty Research and Publications

Life-long learning is an ancient concept. The young are unaware of it. A beginning practitioner, often blinded by ego, ignores its value. The seasoned veteran, haunted by challenges, wonders how it passed him by. History can and does often teach us lessons. In 1787, Benjamin Franklin stood up to address the American Constitutional Convention and urged his fellow patriots to sign the document. At the age of 81, he was the oldest person in the group. He acknowledged having opened his mind to contrarian viewpoints from his younger colleagues. Franklin spoke these words: “If you are convinced that you know …

Bioresorbable Composite Polymeric Materials For Tissue Engineering Applications, Sakineh Hajebi, Saeed Mohammadi Nasr, Navid Rabiee, Mojtaba Bagherzadeh, Sepideh Ahmadi, Mohammad Rabiee, Mohammadreza Tahriri, Lobat Tayebi, Michael R. Hamblin

School of Dentistry Faculty Research and Publications

This review covers the development of bioresorbable polymeric composites for applications in tissue engineering. Various commercially available bioresorbable polymers are described, with emphasis on recent bioresorbable composites based on natural and synthetic polymers. Bioresorbable polymers contain hydrolyzable bonds, which are subjected to chemical degradation via either reactive hydrolysis or enzyme-catalyzed active hydrolysis. For synthetic polymers, chemical hydrolysis is the most important mode of degradation. The degradation rate can be controlled by varying the molecular weight and crystallinity. Examples of bioresorbable polymers are: polyurethane, poly(D,L)lactide, poly(lactic-co-glycolic) acid, poly(α-hydroxy acids), cross-linked polyester hydrogels, poly(orthoesters), polyanhydrides and polyethylene glycol.

Proanthocyanidin Block Arrays (Pacbar) For Comprehensive Capture And Delineation Of Proanthocyanidin Structures, Shuxi Jing, Wayne E. Zeller, Daneel Ferreira, Bin Zhou, Joo-Won Nam, Ana K. Bedran-Russo, Shao-Nong Chen, Guido F. Pauli

School of Dentistry Faculty Research and Publications

Proanthocyanidins (PACs) are near-ubiquitous and chemically complex metabolites, prototypical of higher plants. Their roles in food/feed/nutrition and ethnomedicine are widely recognized but poorly understood. With the analysis of evidence that underlies this challenge, this perspective identifies shortcomings in capturing and delineating PAC structures as key factors. While several groups have forwarded new representations, a consensus method that captures PAC structures concisely and offers high integrity for electronic storage is required to reduce confusion in this expansive field. The PAC block arrays (PACBAR) system fills this gap by providing precise and human- and machine-readable structural descriptors that capture PAC metabolomic structural …
