Study of the persistence of the anti-inflammatory effect observed after application of preparations containing organic ultraviolet filters.

Int. J. Pharm. 476(1-2) , 160-3, (2015)

Given that previous studies have highlighted the anti-inflammatory nature, which is influenced by UV radiation, of a certain number of ultraviolet filters currently used in Europe, it seemed interesting to evaluate the persistence of this type of effect. The ...

Abiogenic Syntheses of Lipoamino Acids and Lipopeptides and their Prebiotic Significance.

Orig. Life Evol. Biosph. 45 , 427-37, (2015)

Researchers have formed peptide bonds under a variety of presumed prebiotic conditions. Here it is proposed that these same conditions would have also formed amide bonds between fatty acids and amino acids, producing phosphate-free amphipathic lipoamino acids...

Structural insights into methanol-stable variants of lipase T6 from Geobacillus stearothermophilus.

Appl. Microbiol. Biotechnol. 99 , 9449-61, (2015)

Enzymatic production of biodiesel by transesterification of triglycerides and alcohol, catalyzed by lipases, offers an environmentally friendly and efficient alternative to the chemically catalyzed process while using low-grade feedstocks. Methanol is utilize...

Induction of Hepatic and Endothelial Differentiation by Perfusion in a Three-Dimensional Cell Culture Model of Human Fetal Liver.

Tissue Eng. Part C Methods 21 , 705-15, (2015)

The development of functional engineered tissue constructs depends on high cell densities and appropriate vascularization. In this study we implemented a four-compartment three-dimensional perfusion bioreactor culture model for studying the effects of medium ...

Determining fatty acids by desorption/ionization mass spectrometry using thin-layer chromatography substrates.

Anal. Bioanal. Chem 407 , 4513-22, (2015)

In this study, we demonstrate the application of ambient mass spectrometry for measuring fatty acids from various biological sample matrices such as olive oil, fish oil, salmon, and human serum. Optimum performance was obtained after spotting samples onto thi...

Sono-intercalation of CdS nanoparticles into the layers of titanate facilitates the sunlight degradation of Congo red.

J. Colloid. Interface Sci. 462 , 130-9, (2015)

In this paper, the degradation of Congo red (CR) as a dye was investigated by a new synthetic photocatalyst. The synthesis was done through the intercalation of CdS in the layers of titanate (K2Ti4O9) by the assistance of ultrasound. The photocatalyst was pre...

Dietary stearic acid leads to a reduction of visceral adipose tissue in athymic nude mice.

PLoS ONE 9(9) , e104083, (2014)

Stearic acid (C18:0) is a long chain dietary saturated fatty acid that has been shown to reduce metastatic tumor burden. Based on preliminary observations and the growing evidence that visceral fat is related to metastasis and decreased survival, we hypothesi...

Paired-ion electrospray ionization--triple quadrupole tandem mass spectrometry for quantification of anionic surfactants in waters.

Talanta 143 , 320-7, (2015)

A new paired ion electrospray ionization tandem mass spectrometry method for determination of anionic surfactants in water samples was developed. In this method, dicationic ion-pairing reagents were complexed with monoanionic analytes to facilitate analyte de...

Physiology and pathophysiology of organic acids in cerebrospinal fluid.

J. Inherit. Metab. Dis. 16(4) , 648-69, (1993)

Concentrations of organic acids in cerebrospinal fluid (CSF) appear to be directly dependent upon their rate of production in the brain. There is evidence that the net release of short-chain monocarboxylic acids from the brain is a major route for removing th...

HMDB: a knowledgebase for the human metabolome.

Nucleic Acids Res. 37(Database issue) , D603-10, (2009)

The Human Metabolome Database (HMDB, http://www.hmdb.ca) is a richly annotated resource that is designed to address the broad needs of biochemists, clinical chemists, physicians, medical geneticists, nutritionists and members of the metabolomics community. Si...
