Optimization of ultrasonic assisted continuous production of biodiesel using response surface methodology.

Ultrason. Sonochem. 27 , 54-61, (2015)

This paper evaluates and optimizes the continuous production of biodiesel from waste cooking oil. In this research work, methanol and potassium hydroxide were used as catalyst engaging response surface methodology. For this purpose, the central composite expe...

Modification of the cellulosic component of hemp fibers using sulfonic acid derivatives: Surface and thermal characterization.

Carbohydr. Polym. 134 , 230-9, (2015)

The aim of this study was to characterize the surface, morphological, and thermal properties of hemp fibers treated with two commercially available, inexpensive, and water soluble sulfonic acid derivatives. Specifically, the cellulosic component of the fibers...

Cheminformatics analysis of assertions mined from literature that describe drug-induced liver injury in different species.

Chem. Res. Toxicol. 23 , 171-83, (2010)

Drug-induced liver injury is one of the main causes of drug attrition. The ability to predict the liver effects of drug candidates from their chemical structures is critical to help guide experimental drug discovery projects toward safer medicines. In this st...

Adriamycin-induced nephropathy in rats: functional and cellular effects characterized by MRI.

J. Magn. Reson. Imaging 41(3) , 829-40, (2015)

To assess with magnetic resonance imaging (MRI) adriamycin-induced nephropathy in living rats, an established model for proteinuric renal disease was used.Functional information of contrast agent clearance was obtained with dynamic contrast-enhanced (DCE) ima...

Evaluation of chemical components and properties of the jujube fruit using near infrared spectroscopy and chemometrics.

Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 153 , 79-86, (2015)

Near-infrared spectroscopy (NIRS) calibrations were developed for the discrimination of spectra of the jujube (Zizyphus jujuba Mill.) fruit samples from four geographical regions. Prediction models were developed for the quantitative prediction of the content...

Gold Nanoparticles-based Extraction-Free Colorimetric Assay in Organic Media: An Optical Index for Determination of Total Polyphenols in Fat-Rich Samples.

Anal. Chem. 87 , 6905-11, (2015)

In this work, a rapid and simple gold nanoparticle (AuNPs)-based colorimetric assay meets a new type of synthesis of AuNPs in organic medium requiring no sample extraction. The AuNPs synthesis extraction-free approach strategically involves the use of dimethy...

Candida rugosa lipase immobilization on hydrophilic charged gold nanoparticles as promising biocatalysts: Activity and stability investigations.

Colloids Surf. B Biointerfaces 131 , 93-101, (2015)

In this work, a simple and versatile methodology to obtain two different bioconjugated systems has been developed by the immobilization of Candida rugosa lipase (CRL) on hydrophilic gold nanoparticles functionalized with 2-diethylaminoethanethiol hydrochlorid...

Transporter-mediated uptake of UDP-glucuronic acid by human liver microsomes: assay conditions, kinetics, and inhibition.

Drug Metab. Dispos. 43(1) , 147-53, (2014)

This study characterized the kinetics, variability, and factors that affect UDP-glucuronic acid (UDP-GlcUA) uptake by human liver microsomes (HLM). Biphasic kinetics were observed for UDP-GlcUA uptake by HLM. Uptake affinities (assessed as Kd) of the high- an...

Ultra-high throughput synthesis of nanoparticles with homogeneous size distribution using a coaxial turbulent jet mixer.

ACS Nano 8(6) , 6056-65, (2014)

High-throughput production of nanoparticles (NPs) with controlled quality is critical for their clinical translation into effective nanomedicines for diagnostics and therapeutics. Here we report a simple and versatile coaxial turbulent jet mixer that can synt...

Ionic liquid-mediated technology to produce cellulose nanocrystals directly from wood.
