A rapid, sensitive and validated method for the determination of fusaric acid (FA) in several Fusarium strains and different commercial food and feed products is reported based on ultra-performance liquid chromatography. This method requires only crude sample by a simple extraction with methanol, and requires a very short time of 8 min for completion. Separation of FA was performed at injection volume of 1 μl with a 20:80 (v/v) water/acetonitrile mobile phase containing 0.1 % formic acid at a flow rate of 0...

Folic acid (FA) functionalized magnetic bovine serum albumin (BSA) microcapsules (FA-MBMCs) were prepared by a facile sonochemical method, in which FA molecule was immobilized onto the outer walls of microcapsules as a targeting ligand and oleic acid (OA) modifying Fe3O4 magnetic nanoparticles (OA-Fe3O4 MNPs) were wrapped into the microcapsules. The obtained FA-MBMCs possessed a nice spherical morphology with the mean size of 1.4 μm. FA-MBMCs also showed an excellent magnetic and molecular dual-targeted property...

PURPOSE: The aim of this study was to evaluate whether anterior cruciate ligament (ACL) and ACL graft could be imaged using diffusion tensor imaging (DTI) and to provide the DTI metrics for ACL and grafts. MATERIALS AND METHODS: Magnetic resonance imaging and DTI were performed in 40 healthy volunteers and 15 patients with ACL reconstruction. Fiber tracking and other postprocessing steps were performed on the workstation. The fractional anisotropy (FA) and apparent diffusion coefficient (ADC) values of ACL and grafts were determined...

The present study introduces two novel organic matrices for matrix assisted laser desorption/ionization mass spectrometry (MALDI-MS) for the analysis of small molecules. The first matrix is "2-amino-4,5-diphenylfuran-3-carboxylic acid" (also called furoic acid, FA) which was synthesized and then characterized by ultraviolet (UV), infrared (FTIR), nuclear magnetic resonance NMR ((1)H and (13)C) and mass spectrometry. The compound has organic semiconductor properties and exhibits intense UV-absorption which is suitable for the UV-MALDI laser (N2 laser, 337 nm)...

The speciation of uranyl ions in fulvic acid (FA) and humic acid (HA), based on models of larger sizes, is systematically studied using density functional theory (DFT). Four uranyl binding sites are suggested for FA and based on their energetics, the preferential binding sites are proposed. The computed binding sites include two chelating types, one through the carboxylate group and one via the hydroxo group. A systematic way to attain the possible structure for Stevenson's HA model is carried out using a combined molecular dynamics (MD) and quantum chemical approach...

By solid-state reaction and doping, a series of red-emitting phosphors Na(x)Y(0.92-x/3)(MoO(4))(y)(WO(4))(1-y)O(0.5) : zEu(3+) have been synthesized. Through optimization of the process conditions and photoluminescent analysis, one type of red emission is obtained that matches nicely with ultraviolet light-emitting diode (UV-LED) chips.

This paper presents a summary of the evidence review group (ERG) report into the clinical effectiveness and cost-effectiveness of cetuximab for the first-line treatment of metastatic colorectal cancer (mCRC), in accordance with the licensed indication, based upon the manufacturer's submission to the National Institute for Health and Clinical Excellence (NICE) as part of the single technology appraisal process. The ERG project ran between 22 January 2008 and 4 November 2008. The clinical evidence came from two unpublished randomised controlled trials (RCTs) of cetuximab plus chemotherapy versus chemotherapy alone in the first-line treatment of mCRC...

Ca(x)Sr1-x-1.5y-0.5zMoO4:yEu3+ zNa+ red phosphors were prepared by solid-state reaction using Na+ as charge supply for LEDs (light emitting diodes). The content of charge compensator, Ca2+ concentration, synthesis temperature, reaction time, and Eu3+ concentration were the keys to improving the properties of luminescence and crystal structure of red phosphors. The photoluminescence spectra shows the red phosphors are effectively excited at 616 nm by 311 nm, 395 nm, and 465 nm light. The wavelengths of 395 and 465 nm nicely match the widely applied emission wavelengths of ultraviolet or blue LED chips...

We have disclosed a very nice advance of nickel(II)-catalyzed carboannulation reactions. Highly substituted indene derivatives are readily prepared in moderate to excellent yields under very mild reaction conditions in air via a nickel(II)-catalyzed cyclization of propargylic compounds with soft nucleophiles.

OBJECTIVE: We studied whether distal peripheral nerves could be imaged using quantitative diffusion tensor imaging (DTI) with a 3-T MRI scanner, and visualized using tractography. METHODS: Altogether 6 healthy subjects were studied. The diffusion was quantified with apparent diffusion coefficient (ADC) and fractional anisotropy (FA) maps, and the direction of main diffusivity was visualized with color-coded orientation maps and tractography. RESULTS: We present the first DTI and tractography results of human distal peripheral nerves...

Heterosexual men and women were told they were competing with another same-sex individual for a date with an attractive opposite-sex interviewer. After answering 6 questions, participants were asked to tell the competitor why the interviewer should choose them over the competitor. Participants' videotaped behavior was coded for different behavioral tactics. Men who were more symmetrical and who had a more unrestricted sociosexual orientation were more likely to use direct competition tactics than were less symmetrical and restricted men...
