We report ambient pressure chemical vapor deposition (CVD) growth of single-crystalline NbS2 nanosheets with controlled orientation. On Si and SiO2 substrates, NbS2 nanosheets grow almost perpendicular to the substrate surface. However, when we apply transferred CVD graphene on SiO2 as a substrate, NbS2 sheets grow laterally lying on the graphene. ...

Diimine ligand (DL) 1 significantly exhibited the fluorescence quenching upon binding to guanine. Changing at the para-substituent of the phenyl ring from the hydroxyl to bromo groups reversely enhanced the fluorescence in the presence of guanine. The reverse in the fluorescence selectivity indicated the profound effect of the substituent at ...

BACKGROUND: Postoperatively shed blood salvage is commonly used to reduce allogenic blood transfusion in patients undergoing total hip (THA) and knee arthroplasty (TKA). Autologous blood retransfusion is not devoid of risk. We hypothesized that adding tranexamic acid (TXA) to a restrictive blood transfusion protocol would reduce the need for postoperative ...

An attempt was made to clarify the additive suppressive effects of pranlukast, a cysteinyl leukotriene-receptor (LTR) antagonist, in combination with chlorpheniramine, an antihistamine, on the up-regulation of histamine H1-receptor (H1R) mRNA in toluene 2,4-diisocyanate (TDI)-sensitized rats. Although pre-treatment with pranlukast partially, but significantly, suppressed TDI-induced up-regulation of H1R mRNA and ...

BACKGROUND: A number of models exploring the cost-effectiveness of dabigatran versus warfarin for stroke prevention in atrial fibrillation have been published. These studies found dabigatran was generally cost-effective, considering well-accepted willingness-to-pay thresholds, but estimates of the incremental cost-effectiveness ratios (ICERs) varied, even in the same setting. The objective of this ...

The amyloid hypothesis of Alzheimer's disease (AD) suggests that soluble amyloid β (Aβ) is an initiator of a cascade of events eventually leading to neurodegeneration. Recently, we reported that Aβ deranged Ca(2+) homeostasis specifically in hippocampal astrocytes by targeting key elements of Ca(2+) signaling, such as mGluR5 and IP3 R1. ...
