FEBS Open Bio, EarlyView.Two biomarkers of Alzheimer's disease, amyloid β‐peptide (Aβ) and tau, induce the transformation of U‐251 and other glioblastoma cell lines into neurotoxic A1‐like reactive astrocytes. This transformation is produced by cytokines and is followed by upregulation of PMCA activity and isoform expression, and is closely associated with inflammation, as ...

Accuracy of impressions with different impression materials in angulated implants [PDF]
Nigerian Journal of Clinical Practice, 2013 To evaluate the dimensional accuracy of the resultant (duplicative) casts made from two different impression materials (polyvinyl siloxane and polyether) in parallel and angulated implants.Three definitive master casts (control groups) were fabricated in dental stone with three implants, placed at equi-distance.

Radiopacity of impression materials
Oral Surgery, Oral Medicine, Oral Pathology, 1979The radiographic densitites of twenty-six impression materials were measured and the values expressed as an equivalent thickness of aluminum. Under simulated clinical conditions, only ten of the materials tested could be consistently distinguished from the bone structure in periapical radiographs. It was far more dificult to detect objects with beveled

Impression Materials and Virus
The Journal of the American Dental Association, 1991Results of this study indicate that impression materials vary in their ability to absorb and retain virus. Disinfection procedures specific for each material or groups of materials should be developed.

Cytotoxicity of impression materials
The Journal of Prosthetic Dentistry, 1993The purpose of this study was to assess the potential cytotoxicity of impression materials. The impression material brands tested included Impregum, Reprosil, Surgident, Permlastic, Jeltrate Regular and Jeltrate Fast Set. These impression materials and their components were tested for their possible cytotoxic effects by three different methods.

Reactions to dental impression materials
Contact Dermatitis, 1975In the department of prosthetic dentistry at Groningen, during the past four years, approximately 2,000 persons have been treated with Scutan, an epimine plastic for temporary crowns and bridges and Impregum, a polyether impression material. A total of ten patients complained of untoward reactions. Patch tests with the basic materials were performed on

Viscosity of elastomeric impression materials
The Journal of Prosthetic Dentistry, 1977(1) Some elastomeric impression materials (Omniflex and Impregum) exhibited extreme shear thinning properties. This property was considered useful and these materials can be considered all-purpose. (2) The use of impression materials in syringing applications should not be precluded simply because the substances are thick or heavy during spatulation. A

Impression materials and electrodeposits. Part I: Impression materials
The Journal of Prosthetic Dentistry, 19811. When compared to the master die, all five impression material specimens showed a shrinkage of from 0.07% to 0.23%. When used as substrates for electrodeposition, these dimensions partly predetermined the dimensions of the electrodeposits. (This will be discussed in Part II of this study). 2.
