Fateme Derakhshan-Panah was born in Hamedan (Iran) in 1987. She received her B.S. in Pure Chemistry (2009) and M.S. in Organic Chemistry (2011) from Bu-Ali Sina University, Iran. She is currently working towards her Ph.D. under the supervision of Professor M. A. Zolfigol. Her research interest is organic methodology especially the application of solid acids and ionic liquids in organic synthesis.

We describe a sensitive, specific liquid-chromatographic determination of penbutolol and its 4-hydroxy metabolite in plasma and urine. The method involves a simple organic extraction, evaporation of the solvent, reconstitution in methanol/water, and injection into the chromatograph. Penbutolol, its metabolites, and the internal standard, propranolol, are resolved on a CN reversed-phase column a...

Over the last century, intakes of omega-6 (ω-6) fatty acids in Western diets have dramatically increased, while omega-3 (ω-3) intakes have fallen. Resulting ω-6/ω-3 intake ratios have risen to nutritionally undesirable levels, generally 10 to 15, compared to a possible optimal ratio near 2.3. We report results of the first large-scale, nationwide study of fatty acids in U.S. organic and convent...

anaerobic digestion is the breakdown of biodegradable organic material by microorganisms in the absence of oxygen or in an oxygen-starved environment.this technology is superior to the landfilling and also the aerobic composting. the aim of the present study was to examine whether the effluent volatile fatty acids from the anaerobic acidogenesis of the food waste can be used du to its high valu...

INTRODUCTION Recommended by the National Advisory Council of the Disabled, the Ministry of Health of Singapore supported a nationwide study of inherited metabolic disorders (IMDs). When the 5-year project ended, investigations were provided as a diagnostic service. This paper documents our 13-year experience. MATERIALS AND METHODS Patients with symptoms suggestive of an IMD were referred. Inv...

Case presentation: Male patient, 6 months old, admitted due to seizure associated with severe refractory hypoglycemia. Patient had been experiencing unusual sleepiness for 8 days, and vomiting after feedings. Brain CT showed prominence of the bilateral frontotemporal extra-axial space Sylvian fissures, EEG revealed a slow diffuse moderate disturbance background activity MRI extensive areas diff...

The objective of this work is to determine mepivacaine hydrochloride (MPVHC) as local anesthetic drug. Modified carbon paste ion-selective electrode was used for the determination MPVHC in different dosage forms and biological fluids. study depends on potentiometric titration drug using modified (MCPE) end point indicator electrode. effects composition, conditioning parameters foreign ions perf...

A batch experiment was conducted to examine the effects of six low-molecular-weight organic acids on the mobilization of arsenic and trace metals from a range of contaminated soils. The results showed that the organic acids behaved differently when reacting with soil-borne As and trace metals. Oxalic acid and acetic acid had the strongest and weakest capacity to mobilize the investigated elemen...

The complex mixture of organic compounds in the atmosphere influences climate, air quality, and ecosystem processes. Atmospheric pressure electrospray ionization mass spectrometry (APESI-MS) was evaluated as a potential tool for direct measurement of the total suite of individual dissolved organic matter (DOM) compounds in rainwater. The APESI-MS response was linear to all DOM compounds of atmo...
