Improved methods for detection of β-galactosidase (lacZ) activity in hard tissue [PDF]

open access: yes, 2012
The ß-galactosidase gene (lacZ) of Escherichia coli is widely used as a reporter gene. The expression of lacZ can be detected by enzyme-based histochemical staining using chromogenic substrates such as 5-bromo-4-chloro-3-indolyl-ß-D: -galactoside (X-gal).

Viscoelasticity of periodontal ligament: an analytical model [PDF]

open access: yesMechanics of Advanced Materials and Modern Processes, 2015
Abstract Background Understanding of viscoelastic behaviour of a periodontal membrane under physiological conditions is important for many orthodontic problems. A new analytic model of a nearly incompressible viscoelastic periodontal ligament is suggested, employing symmetrical paraboloids to describe its internal and ...

Polymicrobial periodontal disease triggers a wide radius of effect and unique virome. [PDF]

open access: yes, 2020
Periodontal disease is a microbially-mediated inflammatory disease of tooth-supporting tissues that leads to bone and tissue loss around teeth. Although bacterially-mediated mechanisms of alveolar bone destruction have been widely studied, the effects of
