Autoregulation of Periodontal Ligament Cell Phenotype and Functions by Transforming Growth Factor-β1
During orthodontic tooth movement, mechanical forces acting on periodontal ligament (PDL) cells induce the synthesis of mediators which alter the growth, differentiation, and secretory functions of… Expand

Synthesis of proinflammatory cytokines by human gingival fibroblasts in response to lipopolysaccharides and interleukin-1 beta.
We have examined the ability of gingival fibroblasts (GF) to participate in inflammatory response and function as accessory immune cells. The accessory immune function of GF cells was evaluated by… Expand

Effect of 2-alkynoic acids on in vitro growth of bacterial and mammalian cells.
3-Decynoyl-N-acetylcystamine is known to inhibit the in vitro growth of Escherichia coli but not of yeasts or mammalian cells. Neither the free acid nor the 2 positional isomer is active (L. R. Kass,… Expand

Scanning electron microscopy of epithelial cells grown on enamel, glass and implant materials.
The purpose of the present study was to examine with scanning electron microscopy gingival epithelial cells grown in cell culture on tooth enamel, glass, Vitallium, titanium and vitreous carbon. SGL… Expand

LPS Responsiveness in Periodontal Ligament Cells is Regulated by Tumor Necrosis Factor-α
Gingival fibroblasts function as accessory immune cells and are capable of synthesizing cytokines in response to lipopolysaccharides (LPS) from Gram-negative microbes. Recently, we have isolated,… Expand

Regulation of Periodontal Ligament Cell Functions by Interleukin-1β
ABSTRACT Periodontal ligament (PDL) cells maintain the attachment of the tooth to alveolar bone. These cells reside at a site in which they are challenged frequently by bacterial products and… Expand

Antifungal properties of 2-n-alkyn-1-ols.
Fourteen 2-n-alkynols (C3-C14, C16, and C18) were tested against Aspergillus oryzae, Aspergillus niger, Trichoderma viride, and Myrothecium verrucaria in Sabouraud dextrose agar at pH 5.6 and 7.0.… Expand

Effect of linolenyl alcohol on the in-vitro growth of the oral bacterium Streptococcus mutans.
The effect of primary aliphatic alcohols of varying chain length and degree of unsaturation on bacterial growth was assessed, using Strep. mutans BHT as the main test organism. Unsaturated alcohols,… Expand

Use of lipids to potentiate the antibacterial activity of aminoglycosides.
Linolenyl alcohol has been shown to inhibit the in vitro growth of several species of gram-positive bacteria. Since the double bonds in linolenyl alcohol could undergo autooxidation, the… Expand
