The use of photo-curable resin composite restorations is an essential treatment modality in modern dental practice. The success and longevity of these restorations depend on achieving predictable and effective polymerization. Understanding the dynamics of the polymerization and the effect of light cure units (LCUs) on this process is paramount. The goal of this concise narrative review is to provide a simplified presentation of basic principles of composite chemistry, polymerization reactions, and photo-curing with relevant terminologies. Clinical guidelines for choosing and maintaining LCUs, as well as safety precautions and factors under the control of the clinician are listed. Finally, clinical recommendations of LCUs' usage and monitoring are included to aid practitioners in achieving predictable polymerization during the placement of direct resin composite restorations.

Dementia was a condition I was aware of from a very young age as I witnessed my grandmother decline, and my mother step into the role as a caregiver, health care director and power of attorney. I was taught the foundation for this process by direct observation of my mother's actions. One aspect of caregiving that isn't teachable is the emotional pain, anguish, sadness and guilt that often accompanies that role.

Background: The global ageing population is rising with each year, and with that, the percentage of individuals with Alzheimer's disease (AD) is expected to rise in parallel. Along with age, traumatic brain injury (TBI) is another risk factor for AD. TBI and AD patients demonstrate abnormal inflammatory responses, including that of the inflammasome.

Background: Alzheimer's disease (AD) is the most common global cause of dementia, with no real cure available. Despite extensive genetic findings from large-scale genetic associations and similar studies, our understanding of AD is largely hindered by its long, asymptomatic progression with limited access to human brain tissue. Animal models like the marmoset allow for longitudinal analysis of disease by enabling the assaying of disease-specific phenotypes that mimic human pathophysiology.

Alzheimers Dement (N Y)

Department of Psychiatry, Harvard Medical School Massachusetts General Hospital Boston Massachusetts USA.
Objective: Physical activity (PA) has been linked to reduced Alzheimer's disease (AD) risk. However, less is known about its effects in the AD preclinical stage. We aimed to investigate whether greater PA was associated with lower plasma biomarkers of AD pathology, neural injury, reactive astrocytes, and better cognition in individuals with autosomal-dominant AD due to the presenilin-1 E280A mutation who are virtually guaranteed to develop dementia.

The purpose of this study was to investigate the effects of acetyl tributyl citrate (ATBC) on the mechanical properties, abrasion resistance, and cytotoxicity of a polyurethane-based 3D printing resin for mouthguard applications. The synthesized polycarbonate-based polyurethane acrylate was formulated into digital light processing printing resins with 40 wt% triethylene glycol dimethacrylate, and different percentage of ATBC were added for further characterizations. The mechanical properties and abrasion resistance, ATBC migration, and the cytotoxicity of the resins were evaluated.
