Scanning Acoustic Microscopy (SAM) can deliver information on mechanical properties. For the investigation of bone microstructure we found the acoustic impedance as the most suitable parameter.A spatial resolution of approximately 1 um at 1 GHz allows morphological studies at the level of cellular structures. For quantitative analysis at high frequencies a smooth and plane surface is essential....

OBJECTIVES Glucagon-like peptide 2 (GLP2) is an intestinal growth factor that has been shown to stimulate intestinal growth and reduce disease severity in preclinical models of short bowel syndrome and inflammatory bowel disease. Teduglutide, a recombinant human GLP2 variant (GLP2-2G), has increased half-life and stability as compared to the native GLP2 peptide, but still requires twice daily d...

introduction: insertion or deletion of a guanine in -1607 at promoter region of matrix metalloproteinase-1 enzyme creates two allelic types for this gene in the population: 2g and 1g, respectively. 2g allele contains an extra binding site for ets transcription factors that this may increase the level of gene expression. therefore, aim of this study was investigation of the single guanine insert...

2-O-α-d-Glucopyranosyl-l-ascorbic acid (AA-2G) is one of the stable ascorbic acid (AA) derivatives known as provitamin C agents. We have previously synthesized two types of monoacylated derivatives of AA-2G, 6-O-acyl-2-O-α-d-glucopyranosyl-l-ascorbic acids having a straight-acyl chain of varying length from C₄ to C18 (6-sAcyl-AA-2G) and a branched-acyl chain of varying length from C₆ to C16 (6-...

BACKGROUND Matrix metalloproteinase-1 (MMP-1) plays an important role during the destruction of periodontal tissue. Although multiple studies had focused on the association between MMP-1 g.-1607dupG and periodontitis susceptibility, the results remained inconclusive. The purpose of this meta-analysis was to explore its role in the development of periodontitis. METHODS Retrieved studies from P...

OBJECTIVE Monocyte (MN) recruitment is an essential inflammatory component of many autoimmune diseases, including rheumatoid arthritis (RA). In this study we investigated the ability of 2-fucosyllactose (H-2g), a glucose analog of blood group H antigen to induce MN migration in vivo and determined if H-2g-induced interleukin-8 (IL-8/CXCL8) plays a role in MN ingress in RA. METHODS Sponge gran...

Interstitial collagen gives fetal membranes tensile strength, and membrane rupture has been attributed to collagen degradation. A polymorphism at -1607 in the matrix metalloproteinase-1 (MMP-1) promoter (an insertion of a guanine (G)) creates a core Ets binding site and increases promoter activity. We investigated whether this polymorphism is functionally significant for MMP-1 expression in amn...
