Gorab deficiency in skin dermis accelerates aging and is associated with dysregulation of RCHY1‐mediated P53 ubiquitination

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Based on a dermis fibroblast Gorab knockout mouse model, this study revealed that Gorab deficiency promotes skin aging by influencing RCHY1, causing a decrease in P53 ubiquitination, damaging the activity of HDAC2, further resulting in the accumulation of aging‐related proteins (P53, P21, P16) and a reduction in extracellular matrix (ECM) components ...

Establishment of a mouse model of propylthiouracil‐induced antineutrophil cytoplasmic antibody‐associated vasculitis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This graphical abstract summarizes our study in which we established a novel murine model of antineutrophil cytoplasmic antibody (ANCA)‐associated vasculitis. Neutrophil recruitment was induced using thioglycolate, followed by timed administration of propylthiouracil and phorbol 12‐myristate 13‐acetate to generate DNase I‐resistant neutrophil ...

Constituents of Dental Calculus from Sheep

Nature, 1963
WHILE the crystalline composition of dental calculus in man is well elucidated, very little is known about such calculus in animals. We have had the opportunity of comparing the results of X-ray diffraction examinations of samples of dental calculus from sheep from Dundee, Scotland, and from Greenland.

Electronmicroscopy of Dental Calculus

Science, 1960
Electron microscopy of ultrathin osmium-fixed sections of dental calculus, cut with a diamond knife without prior decalcification, revealed densely mineralized areas entrapping many degenerating microorganisms, within which were deposited similarly electron-dense crystals.

Radiographic Detection of Dental Calculus

Journal of Periodontology, 1987
To determine the sensitivity and specificity of the radiographic detection of calculus, 275 proximal tooth surfaces from 18 patients were evaluated. Standardized periapical radiographs obtained before extraction were coded, batch processed, and evaluated independently by two investigators under optimum viewing conditions.

Formation and Inhibition of Dental Calculus

Journal of Periodontology-Periodontics, 1969
Indeed there has been an " i n f o r m a t i o n exp los ion" i n this f ield, as the author suggests, and it is grati fying to see the fragments being put i n their places. T h i s book cr i t i ca l ly analyzes over 6 0 0 works o n the epidemiology, physiology and c l in i ca l significance of calculus ; its dis ­ t r ibut ion , chemistry ...

Hyaluronic acid in supragingival dental calculus

Calcified Tissue Research, 1977
A method is described for the isolation of heteropolysaccharides from human supragingival calculus. One component was identified as hyaluronic acid, by electrophoretic mobility, testicular hyaluronidase digestion and cetylpyridinium chloride profiles. No sulphated glycosaminoglycans were detected.
