Retinoic acid-treated pluripotent stem cells undergoing neurogenesis present increased aneuploidy and micronuclei formation.

PLoS ONE 6(6) , e20667, (2011)

The existence of loss and gain of chromosomes, known as aneuploidy, has been previously described within the central nervous system. During development, at least one-third of neural progenitor cells (NPCs) are aneuploid. Notably, aneuploid NPCs may survive an...

Determination of tannic acid in industrial wastewater based on chemiluminescence system of KIO₄-H₂O₂-Tween40.

Luminescence 25(5) , 350-4, (2010)

The oxidation reaction of H₂O₂ with KIO₄ can produce chemiluminescence (CL) in the presence of the surfactant Tween40 and the CL intensity of the CL system KIO₄-H₂O₂-Tween40 can be strikingly enhanced after injection of tannic acid. On this basis, a flow inje...

Oceanobacillus neutriphilus sp. nov., isolated from activated sludge in a bioreactor.

Int. J. Syst. Evol. Microbiol. 60(Pt 10) , 2409-14, (2010)

A Gram-stain-positive, neutrophilic, rod-shaped bacterium, strain A1g(T), was isolated from activated sludge of a bioreactor and was subjected to a polyphasic taxonomic characterization. The isolate grew in the presence of 0-17.0 % (w/v) NaCl and at pH 6.0-9....

Isolation of subcellular organelles.

Characterization and antimicrobial activity of a pharmaceutical microemulsion.

Int. J. Pharm. 395 , 154-160, (2010)

The characterization of a pharmaceutical microemulsion system with glycerol monolaurate as oil, ethanol as cosurfactant, Tween 40 as surfactant, sodium diacetate and water, and the antimicrobial activities against Escherichia coli, Staphylococcus aureus, Baci...

Use of Tween 40 and Tween 80 to deliver a mixture of phytochemicals to human colonic adenocarcinoma cell (CaCo-2) monolayers.

Br. J. Nutr. 91(5) , 757-64, (2004)

Epidemiological evidence suggests that dietary intake of carotenoids and tocopherols may influence the risk of certain chronic diseases, such as cancer and CVD. In vitro studies investigating the synergistic effects of mixtures of carotenoids and tocopherols ...

Investigation of phosphorylation status of OdhI protein during penicillin- and Tween 40-triggered glutamate overproduction by Corynebacterium glutamicum.

Appl. Microbiol. Biotechnol. 91(1) , 143-51, (2011)

Glutamate overproduction by Corynebacterium glutamicum is triggered by treatment with penicillin or Tween 40 and is accompanied by a decrease in 2-oxoglutarate dehydrogenase complex (ODHC) activity. We have reported that de novo synthesis of OdhI, which inhib...

Determination of soluble and granular inorganic polyphosphate in Corynebacterium glutamicum.

Appl. Microbiol. Biotechnol. 72(5) , 1099-106, (2006)

Corynebacterium glutamicum forms inorganic polyphosphate (poly P) that may occur as soluble (cytosolic) poly P and/or as volutin granules. A suitable method for monitoring soluble and granular poly P in C. glutamicum was developed and applied to C. glutamicum...

Water-Tween 40/Imwitor 308-isopropyl myristate microemulsions as delivery systems for ketoprofen: small-angle X-ray scattering study.

Int. J. Pharm. 327(1-2) , 170-7, (2006)

Small-angle X-ray scattering technique has been used to study the structural properties of the quaternary microemulsion Tween 40/Imwitor 308/isopropyl myristate/water and of five-component system obtained by the addition of the drug ketoprofen to the original...

Tween 40-based precipitate production observed on modified chromogenic agar and development of biological identification kit for Malassezia species.

Med. Mycol 44(3) , 227-31, (2006)

We developed a simple identification kit for nine species of Malassezia (M. furfur, M. slooffiae, M. sympodialis, M. restricta, M. obtusa, M. globosa, M. pachydermatis, M. dermatis, and M. japonica) based on their biological features. This method utilizes Twe...
