We present first-principles studies of the adsorption of Sb and Ag on clean and Sb-covered Ag (111). For Sb, the substitutional adsorption site is found to be greatly favored with respect to on-surface fcc sites and to subsurface sites, so that a segregating surface alloy layer is formed. Adsorbed silver adatoms are more strongly bound on clean Ag(111) than on Sb-covered Ag. We propose that the...

CCL25/CCR9 chemokine ligand/receptor pair has been reported to play an important role in small bowel (SB) immunity and inflammation. We have previously reported an aberrant SB expression of CCL25 in Crohn's disease (CD) and an increased frequency of CCR9(+) T cells in the peripheral blood of patients with SB inflammatory diseases such as CD and celiac disease. In this study, we have characteriz...

OBJECTIVES We sought to assess the fate of stent (ST)-related side branches (SB) after coronary intervention in patients with in-ST restenosis. BACKGROUND In-ST restenosis constitutes a therapeutic challenge. Although the fate of lesion-related SB after conventional angioplasty or initial coronary stenting is well established, the outcome of ST-related SB in patients with in-ST restenosis und...

OBJECTIVES This study aimed to assess the effect of re-etching of desensitized dentin for five and 10 seconds on marginal microleakage of composite restorations. MATERIALS AND METHODS Class V cavities (4×2×2mm) were prepared on the buccal surfaces of 64 third molars and randomly divided into four groups of 16. In the control group, Single Bond (SB) adhesive was applied after etching. In BB+SB...

BACKGROUND Salvianolic acid B (SB) is an active component isolated from Danshen, a traditional Chinese medicine widely used for the treatment of cardiovascular disorders. Previous study suggested that SB might inhibit adhesion as well as aggregation of platelets by a mechanism involving the integrin α2β1. But, the signal cascades in platelets after SB binding are still not clear. METHODOLOGY/...

Elevated antimony concentrations in aqueous environments from anthropogenic sources 9 is becoming of global concern, here iron oxides are known to strongly adsorb aqueous antimony 10 species with different oxidation states, but the effect of silica on the removal characteristics is not 11 well understood despite being a common component in the environment. In this study, ferrihydrite 12 was syn...

Sodium butyrate (SB) provided orally favours body growth and maturation of the gastrointestinal tract (GIT) in milk-fed pigs. In weaned pigs, conflicting results have been obtained. Therefore, we hypothesised that the effects of SB (3 g/kg DM intake) depend on the period (before v. after weaning) of its oral administration. From the age of 5 d, thirty-two pigs, blocked in quadruplicates within ...
