Modulation Of Osteoclast Differentiation By Epigallocatechin-3-Gallate (Egcg)/Type I Collagen–Coated Titanium Implant Surface In Vitro, Her-Hsiung Huang, Yu-Ying Cheng, Chia-Fei Liu, Wei-Cheng Chen

Journal of Dental Sciences

Background/purpose: Implant osseointegration depends not only on osteogenesis but also on coordinated bone remodeling. Our previous study demonstrated that epigallocatechin-3-gallate (EGCG)/type I collagen–coated titanium (Ti) surfaces enhance angiogenesis and osteogenic differentiation in vitro. However, their influence on osteoclast differentiation remains unclear. This study evaluated the modulatory effects of this coating on osteoclast responses in vitro.

Materials and methods: Sandblasted and acid-etched (SLA) Ti surfaces followed by alkaline treatment (SLAA) were prepared. Type I collagen was immobilized onto SLAA surfaces using the natural crosslinker EGCG (10 or 50 μg/mL). Surface morphology, roughness, hydrophilicity, and functional groups were characterized.

Impact Of Immediate Restoration On Bone Remodeling In The Esthetic Zone: A Randomized Clinical Trial, Hao-Dong Wang, Xin-Hai Lin, Yi-Wen Wu, Hong-Run Zhou, Tai Zhao Wei, Xi Chen, Yi-Qun Tang, Ya-Qin Zhu, Long Jiang

Journal of Dental Sciences

Background/purpose: Traumatic loss of anterior teeth creates esthetic challenges and often requires immediate rehabilitation. Although immediate implant placement and restoration (IIPR) shortens treatment time, strict primary stability limits its use. A native-crown restoration supported by fiber-reinforced composite (FRC) splints may broaden the indications of immediate restoration, but its effectiveness remains unclear. This randomized controlled trial aimed to evaluate the effects of the novel immediate restoration following IIP on peri-implant bone remodeling in anterior esthetic zone trauma during osseointegration.

Materials and methods: Twenty participants undergoing IIP in the anterior maxilla were randomized into two groups. In the experimental group, immediate restorations …

Sleep Restriction Exacerbates Pulpal Inflammation And Impairs Tissue Repair Following Dental Pulp Capping: An In Vivo Animal Study, Siqi Huang, Qian Wang, Ziyu Chen, Guomiao Zhang, Ying Zheng

Journal of Dental Sciences

As a fundamental physiological process, sleep is essential for maintaining systemic homeostasis. Although sleep restriction (SR) has been shown to trigger a systemic inflammatory response, its specific impact on local pulpal inflammation remains poorly understood. In this preliminary study, we investigated the effects of SR on the inflammatory response and reparative capacity of dental pulp in a rat model. Immunohistochemistry and western blotting revealed that, even in intact pulp tissue, SR upregulated the expression of interleukin-6, increased the infiltration of neutrophils, and activated the nuclear factor-kappa B signaling pathway. Subsequent investigations demonstrated that following dental pulp capping, SR provoked an …

Nasal Polyp With Ossification In The Right Maxillary Sinus: Differential Diagnosis Of Radiopaque Lesions In Maxillary Sinus Region, Ssu-Li Li, Shan-Ju Chou, Yang-Che Wu, Chun-Yu Ho

Journal of Dental Sciences

Nasal polyps are soft, droplet-like lumps that develop on the inner lining of the nose or sinuses due to long-term inflammation in those areas. Nasal polyps are common lesions, however, the occurrence of osseous metaplasia within them is relatively rare. Besides, without a CT scan, relying solely on plain X-ray films to assist clinical diagnosis can easily be misleading due to the uncertainty of the lesion’s location. In this report, our treatment steps were described as medical image analysis, removing the lesion, confirming the pathological result, and regularly follow-up. The Caldwell-Luc approach rather than endoscopic surgery was performed due to …

Living With Generative Ai: Considering Constructionist Approaches To Learning And Methodological Implications Of Process Ontologies, Jimin Lee, Nancy Budwig

Psychology

The growing presence of generative artificial intelligence (GenAI) in educational practice raises questions about how learners and educators live with AI and reshapes questions about how learning unfolds across contemporary learning environments. Although research on AI in education has expanded quickly, much of this work continues to frame GenAI in technocentric and static terms, as a tool to be evaluated, rather than as a relational and developmental presence within learners' trajectories. Drawing on constructionist learning theory and post-Cartesian metatheoretical perspectives, this mini review suggests that such framings are insufficient for understanding how learning is enacted in AI-mediated contexts. We propose …

What Kind Of Democracy Is Energy Democracy? Reconsidering Energy Democracy Through Green Democratic Theory, Eric S. Godoy

Faculty Publications - Philosophy

This study examines an energy democracy framework for guiding a just transition to renewable energy, which incorporates democratic methods and values into energy policy decision-making. But as there are a variety of models of democracy (e.g. liberal, ecological, green republican, and socialist), energy democracy is a complex normative concept, which gives rise to ambiguities and confusions. Drawing from political theory, I argue that identifying with a particular kind of democracy provides the framework with a clearer definition, richer normative grounding, and resources for addressing some limitations its critics have identified, such as the reduction of democracy to participation.

Diverse C–C Bond Formation Reactions Catalyzed By Oxidized Palladium Nanoparticles Supported On Marine Shell Waste Powder Via Additive-Free Deposition–Precipitation, Jian Hou, Garrett M. Milligan, Zhicheng Cai, Jun-Hyun Kim

Faculty Publications – Chemistry

The formation of carbon-carbon (C–C) bonds is central to modern organic synthesis. Although the use of conventional Pd-ligand complexes as homogeneous catalysts results in highly effective yields, these systems often face some limitations including high cost, difficult recyclability, and thermal stability. Here, we demonstrate the utilization of palladium (Pd)-derived metals supported on finely ground marine shell waste as a reactive and recyclable catalyst for diverse C–C bond-forming reactions. Oyster shell powder (OSP) derived from problematic biowaste, primarily composed of calcium carbonate, provides abundant anchoring sites to immobilize Pd ions via an additive-free deposition–precipitation method, followed by thermally-induced conversion into oxidized …

Supporting Teachers’ Learning About Technology Accessibility: A Content Analysis Of Asynchronous Professional Development, Mutiara Syifa, Natalie L. Shaheen

Faculty Publications - College of Education

Accessibility is imperative to providing disabled students a free and appropriate technology-mediated public K-12 education. But according to the literature, teachers often lack the requisite knowledge to ensure the technologies they use are accessible. So, we conducted a study to understand what, if any, asynchronous professional development about technology accessibility was available to teachers and other K-12 professionals. The findings indicate that of the free technology accessibility professional development materials in the sample (a) fewer than 20% are designed for teachers, (b) most provide limited information, and (c) fewer than 9% specifically address science, technology, engineering, and mathematics (STEM) subjects. …

Structural Design Of Macroporous Layered Double Hydroxide Catalysts: Alleviating Mass Transport Constraints In Bulkier Triglycerides, Nazrizawati Ahmad Tajuddin, Mohamad Hidayat Haider, Nazarudin Nazarudin

Baghdad Science Journal

Layered double hydroxides (LDHs) serve as potential catalysts for biodiesel production through triglyceride (TAG) transesterification; nevertheless, mass transport limitations hinder their effectiveness, especially with larger TAG molecules. This study addresses this limitation by synthesizing macroporous MgAlLDH and ZnAlLDH using a polystyrene templating method. Thorough characterization reveals the successful formation of macroporous structures with significantly increased physicochemical properties and their structural design compared to conventional LDHs. X-ray Diffraction (XRD) confirmed the successful restoration of the LDH structure following calcination and rehydration, with enhanced crystallinity seen in the macroporous materials. The BET surface area analysis revealed a substantial increase (∼10x for MgAlLDH) …

Effect Of Mycovirus Infection On The Hydrolytic Enzymes Activity Of Fusarium Oxysporum F. Sp. Cubense Tropical Race 4, The Causal Agent Of Banana Fusarium Wilt, Zhi-Qin Lai, Clement Kiing Fook Wong, Nor Ismaliza Binti Mohd Ismail, Ganesan Vadamalai

Baghdad Science Journal

Fusarium oxysporum f.sp cubense Tropical Race 4 also known as Fusarium odoratissimum (FO) is a fungal pathogen affecting banana (Musa spp.). It secretes plant cell-wall degrading enzymes (PCWDEs) to penetrate and colonize roots, resulting in wilting symptoms and host death. Mycovirus is a virus that infects fungus. It was discovered that mycovirus could be a biocontrol agent by causing hypovirulence in fungal pathogens, a typical symptom of suppressed pathogenicity of an infected host. Hypovirulence was also associated to reduced PCWDE activity in several plant fungal pathogens. To date, no hypovirulent mycovirus was reported in FO. Hence, this study …
