The solid base catalysis of sodium salts Lindqvist-type metal oxide clusters was investigated using a Knoevenagel condensation reaction. We successfully synthesized the Ta and Nb mixed-oxide Na8?nHn[(Ta6?xNbx)O19]·15H2O (Na-Ta6?xNbx, n = 0, 1, x 0–6) found them to exhibit activity for proton abstraction from nitrile substrates with pKa value 23.8, which is comparable that conventional MgO. Ta-r...

Abstract Introduction Adequate post-operative analgesia is important for recovery, early rehabilitation and patient satisfaction. We aimed to prove that patients undergoing surgery breast cancer who receive cryotherapy via frozen gel-packs in the immediate postoperative period would report lower pain, require lesser narcotics pain medication. Method This prospective randomized study was conduct...

Abstract Introduction Malnutrition is a key priority on the global health agenda, yet impact of nutritional state cancer surgery across income strata remains poorly described. This study aimed to determine effect malnutrition early postoperative outcomes following elective for colorectal or gastric cancer. Method Multicentre, international prospective cohort consecutive patients undergoing was ...

Background Dendritic cells (DCs) are the most potent antigenpresenting cells, having an important role in linking innate and adaptive immunity. DCs are also critical mediators of immune tolerance and anergy, depending on the type of antigen they encounter. Peripheral blood DCs represent only the 0.1–1% of mononuclear cells and, based on their lineage origins, they can be divided into two major ...

This paper examines the role of the global institutional frameworks on the national processes of innovation diffusion. we focus on the influence of the Kyoto mechanisms on the diffusion of renewable energy technologies in the BRICS countries i.e. Brazil, China India, Russia and South Africa. Our preliminary analysis suggests that the Kyoto Mechanisms may support...
