An efficient green route for the preparation of naphthoxazinones, applying a three-component one-pot condensation reaction of 2-naphthol, aromatic aldehyde and urea in the presence of nano silica supported ferric chloride under solvent-free conditions has been developed. The present procedure offers several advantages such as short reaction time, simple workup, recovery and reusability of the c...

The purposes of these studies were to produce a small animal model of arterial thrombosis for study of novel antithrombotic agents, to validate a simple temperature index of occlusive thrombosis, and to describe the composition of the thrombus. Small thermocouple transducers were fabricated from readily available materials. A thermocouple was inserted under a carotid artery of the anesthetized ...

Small sized magnetite iron oxide nanoparticles (Fe3O4-NPs) with were successfully synthesized on the surface of rice straw using the quick precipitation method in the absence of any heat treatment. Ferric chloride (FeCl3·6H2O), ferrous chloride (FeCl2·4H2O), sodium hydroxide (NaOH) and urea (CH4N2O) were used as Fe3O4-NPs precursors, reducing agent and stabilizer, respectively. The rice straw f...

Norovirus (NV) is an important human pathogen that causes epidemic acute nonbacterial gastroenteritis worldwide. Because of the lack of a cell culture system or an animal model for this virus, studies of drinking water treatment such as separation and disinfection processes are still hampered. We successfully estimated NV removal performance during a coagulation-rapid sand filtration process by...

Ferrous ferric chloride (FFC) is a distinct form of aqueous iron composed of a complex of ferrous chloride and ferric chloride that participates in both oxidation and reduction reactions. The author's previous study showed that the supplementation of culture medium with FFC stimulated the proliferation and differentiation of keratinocytes and melanocytes in newborn mice. FFC also stimulated the...
