The aim of this study was to quantify the expression of E-selectin, intercellular cell adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 ... JR Paysant,A Rupin,TJ Verbeuren - 《Endothelium》 被引量: 10发表: 2009年 Role of estrogen receptor-dependent upregulation of P38...
Oxygen is one of the most critical components of life. Nature has taken billions of years to develop optimal atmospheric oxygen concentrations for human life, evolving from very low, peaking at 30% before reaching 20.95%. There is now increased understan
A small-molecule high-oxygen water dispenser comprises a base, a water supplying device and an oxygen generating device both arranged inside the base, wherein a base frame for the water supplying device is arranged inside the accommodation space of the base, a cold water container above the ...
An acrylate composition, especially useful for producing conformal coatings on circuit board assemblies, includes a photoinitiator and an air-curing system, the latter being comprised of a compound having multiple allyloxy groups in its molecule and a transition metal salt catalyst. The composition is ...
The oxygen molecule was first detected early in the 1770s and was recognized as a chemical element by correctly characterizing its role in combustion and corrosion; it received the proper name ‘oxygen’ in 1777. Interestingly, oxygen is the most abundant chemical element by mass in the Earth’...
This paper systematically investigates the roles of lattice oxygen in V 2O 5 and activated coke over coke-supported V 2O 5 catalysts in SO 2 removal process at 200 °C. The results show that one SO 2 molecule reacts with one O atom in a surface V 2O 5 molecule to form an intermedi...
The key concept is to use nano-clusters (small size is essential to maximise the effect of adsorbates on metal clusters) that donate or accept a significant amount of charge upon adsorption of a target molecule, so as to affect electron transport in the nanotube. This concept was first ...
Whereas chemical oxidation resulted in cluster decomposition, reduction with decamethylcobaltocene yielded stable salts of formula [Cp*2Co][(ArN)14Ta6O] (Ar=Ph, Ar=p-MeC6H4). Small-molecule reactivity studies on one of these clusters showed that its imido functionalities are moderately reactive ...
