Remaining Dentine Thickness Following Tooth Preparation And Its Impact On Dentine – Pulp Complex, Rudina Berani, Merita Barani Sveqla

UBT International Conference

There are many factors accused of causing pulpal damage, but studies indicate that endodontic complications after placement of fixed prosthetic crowns and bridges are entirely iatrogenic and as a consequence of a deep tooth preparation. In 2mm of the remaining dentine thickness after preparation, there are significant reductions in cellular cell adhesion molecules in the pulp of the prepared tooth data compared to those intact. Researchers confirm that even this decline may be an expression of early stages of pulp inflammation. According to Murray & co, the number of odontoblasts in a dentine thickness of 2.5-0.5mm, was reduced by 13.6%; …

Worship, Ante Jeroncic

Andrews Autumn Conference on Religion and Science

Abstract

The devotional explores the intersection of ethics and epistemology through the “deadly sin” of acedia (or sloth) and the moral dimension of ignorance entailed in it. In particular, it juxtaposes the acedia-ignorance nexus to 2 Peter 1:5-9 and its argument about the interconnectedness of virtue—including enkrateia or self-control—and access to (some forms of) truth.

An Exotic Journey Into The Commonplace, Linda Weintraub

Artizein: Arts and Teaching Journal

Standardized mass-produced commodities, reliance upon electronic data-gathering, and sanitized material manipulations are so pervasive in contemporary industrialized societies that today, ‘exotic’ experiences activate sensory interactions with the substances and conditions of planet Earth. ‘Plugging in’ to the international flow of goods and information commonly results in ‘tuning out’ connections with the immediate surroundings. This essay highlights the capacity of the un-aided mind and body to explore the wondrous complexity of planet Earth. The first part presents four artists who, by engaging geological, biological, and meteorological components of their surroundings, exchange dematerialized surfing activities offered by the World Wide Web, for …

Chemistry & Biochemistry Faculty Works

Nanomedicine utilizes the remarkable properties of nanomaterials for the diagnosis, treatment, and prevention of disease. Many of these nanomaterials have been shown to have robust antioxidative properties, potentially functioning as strong scavengers of reactive oxygen species. Conversely, several nanomaterials have also been shown to promote the generation of reactive oxygen species, which may precipitate the onset of oxidative stress, a state that is thought to contribute to the development of a variety of adverse conditions. As such, the impacts of nanomaterials on biological entities are often associated with and influenced by their specific redox properties. In this review, we overview …

Primary Cilium-Dependent Signaling Mechanisms, Rajasekharreddy Pala, Nedaa Alomari, Surya M. Nauli

Pharmacy Faculty Articles and Research

Primary cilia are hair-like organelles and play crucial roles in vertebrate development, organogenesis, health, and many genetic disorders. A primary cilium is a mechano-sensory organelle that responds to mechanical stimuli in the micro-environment. A cilium is also a chemosensor that senses chemical signals surrounding a cell. The overall function of a cilium is therefore to act as a communication hub to transfer extracellular signals into intracellular responses. Although intracellular calcium has been one of the most studied signaling messengers that transmit extracellular signals into the cells, calcium signaling by various ion channels remains a topic of interest in the field. …
