Background: Restoring bonding composite to silver diamine fluoride (SDF)-treated enamel is challenging. This study investigates if phosphoric acid etch restores bond strength SDF-treated using universal adhesives. Methods: Twenty-four recently extracted permanent teeth were randomly divided into 4 (2 experimental (SDF) and 2 control (CTR)) groups: SDF+Water: SDF (1 min) then water rinse (15 mL)...

This paper describes our system for generating Chinese aspect expressions. In the system, the semantics of different aspects is characterized by specific temporal and conceptual features. The semantic applicability conditions of each individual aspect are theoretically represented by an aspect selection function (ASF). The generation is realized by evaluating implemented inquiries which formall...

objective: transplantation of mesenchymal stem cells (mscs) can promote functional recovery of the brain after hypoxic-ischemic brain damage (hibd). however, the mechanism regulating msc migration to a hypoxic-ischemic lesion is poorly understood. interaction between stromal cell-derived factor-1α (sdf-1α) and its cognate receptor cxc chemokine receptor 4 (cxcr4) is crucial for homing and migra...

Stromal derived factors, SDFs, are a loosely defined group of molecules that may be generated by stromal cells. Two of the stromal derived factors, SDF-1 and SDF-4 belong to the chemokine family. Other SDFs, such as SDF-2 and SDF-5 are not well defined and their biological functions are less known. Although SDF-1 and its receptor have been strongly indicated in the progression of various cancer...

Semen analysis, sperm DNA fragmentation (SDF) and hypo-osmotic swelling test (HOST) are usually performed for the evaluation of sperm fertilizing ability. There are some debates over the necessity of SDF and HOST incorporation in male infertility work-up.Semen of 77 men was evaluated by SDF and HOST through three semen analyses. Sperm parameters were arranged into different categories: <5%, 5-1...

Various in vitro preconditioning strategies have been implemented to increase the regenerative capacity of MSCs. Among them are modulation culture atmosphere (hypoxia or anoxia), three-dimensional (3D), addition trophic factors (in form growth factors, cytokines hormones), lipopolysaccharides, and pharmacological agents. Preconditioning mesenchymal stem cells by culturing a hypoxic environment,...

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 &lt;i&gt;Streptoc...
