Plasmid-mediated mineralization of carbofuran by Sphingomonas sp. strain CF06.

Feng, X, Ou, L T, Ogram, A

A bacterial strain (CF06) that mineralized both the carbonyl group and the aromatic ring of the insecticide carbofuran and that is capable of using carbofuran as a sole source of carbon and nitrogen...

High- and low-abundance chemoreceptors in Escherichia coli: differential activities associated with closely related cytoplasmic domains.

Feng, X, Baumgartner, J W, Hazelbauer, G L

In Escherichia coli, two high-abundance chemoreceptors are present in cellular dosages approximately ten-fold greater than two low-abundance receptors. In the absence of high-abundance receptors,...

Expression and function of the equine herpesvirus 1 virion-associated host shutoff homolog.

Feng, X, Thompson, Y G, Lewis, J B, Caughman, G B

The ability of herpes simplex virus types 1 and 2 (HSV-1 and HSV-2, respectively) to repress host cell protein synthesis early in infection has been studied extensively and found to involve the...

Dot-immunogold filtration assay as a screening test for syphilis.

Huang, Q, Lan, X, Tong, T, Wu, X, Chen, M, Feng, X, ...

A dot-immunogold filtration assay (DIGFA) for the rapid detection of reaginic antibody in the serum of syphilitic patients was developed. The assay was simple, rapid, and reproducible. The test...

Identification of heparin-binding EGF-like growth factor as a target in intercellular regulation of epidermal basal cell growth by suprabasal retinoic acid receptors.

Xiao, J H, Feng, X, Di, W, Peng, Z H, Li, L A, Chambon, P, ...

The role of retinoic acid receptors (RARs) in intercellular regulation of cell growth was assessed by targeting a dominant-negative RARalpha mutant (dnRARalpha) to differentiated suprabasal cells of...

Genetic Analysis of a Cryptosporidium parvum Human Genotype 1 Isolate Passaged through Different Host Species

Akiyoshi, D. E., Feng, X., Buckholt, M. A., Widmer, G., Tzipori, S.

Cryptosporidium parvum TU502, a genotype 1 isolate of human origin, was passaged through three different mammalian hosts, including humans, pigs, and calves. It was confirmed to be genotype 1 by...

Post-transcriptional suppression of cytosolic ascorbate peroxidase expression during pathogen-induced programmed cell death in tobacco.

Mittler, R, Feng, X, Cohen, M

As a means to eliminate pathogen-infected cells and prevent diseases, programmed cell death (PCD) appears to be a defense strategy employed by most multicellular organisms. Recent studies have...

The observation of the local ordering characteristics of spermidine-condensed DNA: atomic force microscopy and polarizing microscopy studies.

Lin, Z, Wang, C, Feng, X, Liu, M, Li, J, Bai, C

Condensation of DNA by multivalent cations can provide useful insights into the physical factors governing the folding and packaging of DNA in vivo. In this work, local ordered structures of...

Stable isotopes examined across a migratory divide in Scandinavian willow warblers (Phylloscopus trochilus trochilus and Phylloscopus trochilus acredula) reflect their African winter quarters.

Chamberlain, C P, Bensch, S, Feng, X, Akesson, S, Andersson, T

The C and N isotopes of feathers from two subspecies of willow warblers Phylloscopus trochilus trochilus and Phylloscopus trochilus acredula) are isotopically distinct. Our analysis of 138 adult...
