Carbonaceous nanofiber membrane functionalized by beta-cyclodextrins for molecular filtration.

Ping Chen et al.

ACS nano, 5(7), 5928-5935 (2011-06-15)

In this paper, we report the fabrication of carbonaceous nanofiber (CNF) membranes functionalized by beta-cyclodextrins (CNF-β-CD membrane) and their application for molecular filtration. The chemically synthesized carbonaceous nanofibers were first functionalized by β-CD, and the free-standing CNF membrane can be

Use of a pharmaceutically adulterated dietary supplement, Pai You Guo, among Brazilian-born women in the United States.

Pieter A Cohen et al.

Journal of general internal medicine, 27(1), 51-56 (2011-08-17)

Pai You Guo is a weight loss supplement manufactured in China and adulterated with the banned pharmaceutical products sibutramine and phenolphthalein. The US Food and Drug Administration (FDA) announced a voluntary recall of Pai You Guo in 2009, yet clinicians

Functional electrospun polystyrene nanofibers incorporating α-, β-, and γ-cyclodextrins: comparison of molecular filter performance.

Tamer Uyar et al.

ACS nano, 4(9), 5121-5130 (2010-08-20)

Electrospinning has been used to successfully create polystyrene (PS) nanofibers containing either of three different types of cyclodextrin (CD); α-CD, β-CD, and γ-CD. These three CDs are chosen because they have different sized cavities that potentially allow for selective inclusion

The preparation and characterization of non-covalently functionalized graphene.

Nantao Hu et al.

Journal of nanoscience and nanotechnology, 12(1), 99-104 (2012-04-25)

Recently, much work has focused on the exfoliation of graphene through a combination of oxidation and sonication procedures, followed by reduction through chemical methods. We demonstrated that the individual graphene oxide sheets can be readily reduced by using phenolphthalin as

Rational quantitative structure-activity relationship (RQSAR) screen for PXR and CAR isoform-specific nuclear receptor ligands.

Ann M Dring et al.

Chemico-biological interactions, 188(3), 512-525 (2010-09-28)

Constitutive androstane receptor (CAR) and pregnane X receptor (PXR) are closely related orphan nuclear receptor proteins that share several ligands and target overlapping sets of genes involved in homeostasis and all phases of drug metabolism. CAR and PXR are involved
