Background: This research aimed to evaluate the marginal and internal gaps of crowns, which were produced using both digital and conventional impression techniques and cemented with various types of cement.
Material And Methods: For the full ceramic crown restoration, an anatomically prepared acrylic first molar phantom tooth (Frasaco GmbH, Germany) was scanned with Scanner S600 ARTI (Zirkonzahn). 160 PMMA analogues produced from the milling unit.
Altered Functional Responses of the Retina in B6 Albino Tyrc/c Mice.
Invest Ophthalmol Vis Sci
August 2024
Article Synopsis
- Mammals with albinism have impaired visual discrimination and altered retinal cell makeup, affecting how retinal ganglion cells (RGCs) function.
- The study used a mouse model of oculocutaneous albinism (Tyrc/c) to analyze RGC responses to light and assess differences in their receptive fields compared to normal mice.
- Results showed similar receptive field sizes between albinism-affected and normal RGCs, but the albinism-affected RGCs exhibited more OFF responses and different polarity changes, indicating unusual adaptations during development due to the lack of eye pigments.
Article Synopsis
- The brain's ability to predict future sensory inputs and signal prediction errors is crucial, and this study focuses on how this occurs in the retina.
- Researchers discovered that depressing inhibitory synapses affects the timing of responses to stimuli that are omitted during periodic stimulation.
- Their model suggests that a constant response latency to an omitted stimulus relies on the presence of enough stimulation flashes, highlighting the importance of these synapses in generating accurate predictive responses in the retina and possibly other brain regions.
Masking Ability of Monolithic CAD/CAM Laminate Veneers Over Different Resin Cement Shades and Substrate Colors.
Int J Prosthodont
September 2024
Purpose: To compare the masking ability of monolithic CAD/CAM veneers placed over different resin cement shades and substrate colors.
Materials And Methods: Veneers were milled from four different monolithic CAD/CAM restorative materials: feldspathic ceramic (VMII), lithium disilicate ceramic (Emax CAD), zirconiareinforced lithium silicate ceramic (VS), and high-translucency zirconia ceramic (YZ-XT). Veneers were luted on natural tooth-colored (ND1) or discolored substrates (ND3 or ND5) using two different resin cement shades (opaque white or translucent).
Subdivisions of mouse whisker somatosensory thalamus project to cortex in a region-specific and layer-specific manner. However, a clear anatomical dissection of these pathways and their functional properties during whisker sensation is lacking. Here, we use anterograde trans-synaptic viral vectors to identify three specific thalamic subpopulations based on their connectivity with brainstem.
