This study investigated the effects of silver diamine fluoride (SDF) and potassium iodide (KI) treatments on acid resistance dentin exposed to secondary caries. Sixteen bovine specimens with artificially induced caries were assigned following four groups: untreated negative control, positive SDF-treated (SDF), SDF KI-treated (SDFKI). Multispecies cariogenic biofilms containing <i>Streptoc...

زمینه و هدف: تا کنون در مطالعات مختلفی به بررسی موبیلیزاسیون سلول های بنیادی خونساز به منظور پیوند و اهمیت سیگنال های بتا آدرنرژیکی در القای این فرآیند، پرداخته شده است. با این وجود، اطلاعات کمی درباره نحوه اثر سیگنال های بتا آدرنرژیکی در موبیلیزاسیون سلول های بنیادی خونساز ، موجود است. sdf-1 در موبیلیزاسیون سلول های بنیادی خونساز، نقش کلیدی ایفا می کند. این کموکاین توسط سلول های بنیادی مزانشیم...

Background: It is now well established that several environmental stress factors cause activation of p38 MAP kinase and JNK in various cell types to produce chemokines. Objective: To investigate the expression of CXC chemokines Gro/KC and SDF- 1a in rat's H4 hepatoma cells in response to heat shock, hyperosmolarity and oxidative stress. Methods: Hepatoma cells were maintained in MEM medium. Cel...

BACKGROUND Stromal cell-derived factor-1 (SDF-1) is a chemokine considered to play an important role in the trafficking of hematopoietic stem cells. Given the close relationship between hematopoietic stem cells and endothelial progenitor cells (EPCs), we investigated the effect of SDF-1 on EPC-mediated vasculogenesis. METHODS AND RESULTS Flow cytometric analysis demonstrated expression of CXC...

background: although the effectiveness of ginger as an antioxidant agent has been exploited, little human research has been conducted on its activity on male reproductive functions. objective: this study was designed to investigate the effects of ginger (zingiber officinale) on sperm dna fragmentation (sdf) in infertile men. materials and methods: this randomized double-blind, placebo-controlle...

Stromal cell-derived factor 1 (SDF-1/CXCL12/PBSF) plays important roles in the biological and physiological functions of haematopoietic and mesenchymal stem cells. This chemokine regulates the formation of multiple organ systems during embryogenesis. However, its roles in skeletal development remain unclear. Here we investigated the roles of SDF-1 in chondrocyte differentiation. We demonstrated...

The chemoattractant stromal cell-derived factor-1 (SDF-1) and its receptor CXC chemokine receptor 4 (CXCR4) are key modulators of immune function. In the developing brain, SDF-1 is crucial for neuronal guidance; however, cerebral functions of SDF-1/CXCR4 in adulthood are unclear. Here, we examine the cellular expression of SDF-1 isoforms and CXCR4 in the brain of mice receiving systemic lipopol...

Stromal cell-derived factor-1 (SDF-1/CXCL12) is one of the essential chemokines, which mediates hematopoietic differentiations. However, the mechanism by which SDF-1 expression is regulated in granulocyte differentiation is poorly understood. Here, we suggest a novel mechanism by which all-trans-retinoic acid (ATRA) induces the expression of SDF-1 during the differentiation of promyelomonocytic...
