A triple system of Fe(III)/sulfite/persulfate: Decolorization and mineralization of reactive Brilliant Red X-3B in aqueous solution at near-neutral pH values
We report herein the use of ferric iron (Fe3+) and sulfite (SO3 2−) to activate persulfate (S2O8 2−). Decolorization and mineralization of reactive Brilliant Red X-3B (a model azo dye) by an Fe(III)/sulfite/persulfate triple system have been investigated in aqueous solutions. Initial pH and dissolved oxygen are important factors influencing X-3B decolorization in this system. The rapid decolorization process occurred in 30min and about 85% of X-3B was decolorized in this triple system at initial pH 6.0. Moreover, about 66.4% of the TOC was removed through reaction for 36h. The generation of SO4 •− and HO• were id...

Unusual anti-leukemia activity of nanoformulated naproxen and other non-steroidal anti-inflammatory drugs.
Abstract The non-steroidal anti-inflammatory drugs (NSAIDs) are the most widely used pharmaceuticals worldwide. Interestingly, many of them have significant anticancer properties too. However, the poor water solubility of certain NSAIDs limits their application for cancer treatment. Nanosizing of such drugs can help to improve the solubility and this may result in enhanced anticancer activities too. Moreover, over dosages and the accompanying side effects of NSAIDs can be minimized by improving their solubility and bioavailability. Successful nanoformulation of three NSAIDs: ibuprofen (IBP), ketoprufen (KP) and na...

Newly Approved Agents for the Treatment and Prevention of Pediatric Migraine
AbstractTreatment of pediatric migraine remains an unmet medical need. There continues to be a paucity of pediatric randomized controlled trials for the treatment of migraine, both in the acute and preventive settings. Pediatric studies are often complicated by high placebo-response rates and much of our current practice is based on adult trials. This lack of significant pediatric studies results in a wide variation in migraine management both amongst clinicians and between institutions, and evidence-based treatments are not always administered. In this article, we aim to briefly review newly approved abortive and preventi...

Repurposing FDA-approved drugs for anti-aging therapies.
Abstract There is great interest in drugs that are capable of modulating multiple aging pathways, thereby delaying the onset and progression of aging. Effective strategies for drug development include the repurposing of existing drugs already approved by the FDA for human therapy. FDA approved drugs have known mechanisms of action and have been thoroughly screened for safety. Although there has been extensive scientific activity in repurposing drugs for disease therapy, there has been little testing of these drugs for their effects on aging. The pool of FDA approved drugs therefore represents a large reservoir of ...

Determination of ibuprofen, naproxen and diclofenac in aqueous samples using a multi-template molecularly imprinted polymer as selective adsorbent for solid-phase extraction
This study describes the application of multi-template molecularly imprinted polymer (MIP) as selective sorbent in the solid-phase extraction (SPE) of naproxen, ibuprofen and diclofenac from wastewater and river water. MIP was synthesized at 70°C by employing naproxen, ibuprofen and diclofenac as multi-templates, ethylene glycol dimethacrylate, 2-vinyl pyridine and toluene as cross-linker, functional monomer and porogen, respectively. Wastewater and river water samples (pH 2.5) were percolated through SPE cartridge packed with 50mg of the MIP. The cartridge was washed with 2mL of methanol-water 10:90% (v:v) prior to eluti...

Suitability of passive sampling for the monitoring of pharmaceuticals in Finnish surface waters.
Abstract The occurrence of five pharmaceuticals, consisting of four anti-inflammatory and one antiepileptic drug, was studied by passive sampling and grab sampling in northern Lake Päijänne and River Vantaa. The passive sampling was performed by using Chemcatcher® sampler with a SDB-RPS Empore disk as a receiving phase. In Lake Päijänne, the sampling was conducted during summer 2013 at four locations near the discharge point of a wastewater treatment plant and in the years 2013 and 2015 at four locations along River Vantaa. The samples were analyzed by liquid chromatography coupled to tandem mass spectrometry...
