Comparison of Ibuprofen with Ketorolac on the Control of Renal Colic Pain: A Meta-Analysis of Randomized Controlled Studies.

Purpose: The comparison of ibuprofen with ketorolac remains controversial for the pain control of renal colic. We therefore conduct this meta-analysis to compare the analgesic efficacy of ibuprofen with ketorolac for renal colic.

Methods: We have searched PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through December 2022 for randomized controlled trials (RCTs) assessing the analgesic efficacy of ibuprofen in comparison with ketorolac for renal colic.

2-Methylimidazole directed ambient synthesis of zinc-cobalt LDH nanosheets for efficient oxygen evolution reaction.

It is a highly desired yet challenging task to replace rare and expensive noble metal catalysts with inexpensive and earth-abundant metal ones in electrochemical sustainable chemistry field. Herein, the bimetallic zinc-cobalt layered double hydroxide nanosheets (ZnCo-LDH NS) have been facilely synthesized using 2-methylimidazole as a bifunctional alkali source (OH) and a morphological controlling reagent by the one-step room-temperature reaction. The mechanism study shows that the weak organic base of 2-methylimidazole-induced slow release of OH in water/ethanol is the controlling factor for the formation of the LDH nanosheets.

Selective binding of Pb with manganese-terephthalic acid MOF/SWCNTs: Theoretical modeling, experimental study and electroanalytical application.

A nanocomposite of flake-shaped manganese-terephthalic acid MOF/single-walled carbon nanotubes (Mn(TPA)-SWCNTs) was synthesized using manganese chloride, terephthalic acid and SWCNTs as raw materials. Theoretical modeling study shows that the Mn(TPA) component has stronger adsorption ability to lead ion (Pb) than the other common heavy metal ions, which is in good agreement with the result of electrochemical assay. Then, the Mn(TPA)-SWCNTs were used as a sensing matrix for the voltammetric determination of Pb.

Hydroxyapatite/chemically reduced graphene oxide composite: Environment-friendly synthesis and high-performance electrochemical sensing for hydrazine.

It is unexpectedly found that, the in-situ growth of hydroxyapatite (HAP) on graphene oxide (GO) under a moderate temperature (85°C) can effectively trigger the reduction of GO, which needs neither extra reducing agents nor high-temperature thermal treatment. The transmission electron microscope (TEM) experiment demonstrates that the rod-like HAP particles are well attached on the surface of reduced GO (rGO) to form the composite. Electrochemical sensing assays show that the synthesized HAP-rGO nanocomposite presents excellent electrocatalytic capacity for the oxidation of a toxic chemical of hydrazine.
