Focal dermal hypoplasia (Goltz syndrome) is a rare syndrome comprising developmental anomalies of tissues and organs of mesoectodermal origin. As a result, there are abnormalities of the eyes, skin, oral structures, musculoskeletal system and central nervous system. This article describes the case of a four-year-old female with focal dermal hypoplasia (FDH) who displayed many of the oral featur...

The in situ regeneration of reduced nicotinamide cofactors (NAD(P)H) is necessary for practical synthesis of many important chemicals. Here, we report the engineering of a highly stable and active mutant phosphite dehydrogenase (12x-A176R PTDH) from Pseudomonas stutzeri and evaluation of its potential as an effective NADPH regeneration system in an enzyme membrane reactor. Two practically impor...

Human serum albumin (HSA) is the major protein component of blood plasma and serves as a transporter for thyroxine and other hydrophobic compounds such as fatty acids and bilirubin. We report here a structural characterization of HSA-thyroxine interactions. Using crystallographic analyses we have identified four binding sites for thyroxine on HSA distributed in subdomains IIA, IIIA, and IIIB. M...

The calculation of loop amplitudes with parity violation or spin effects within dimensional regularization needs a consistent definition of γ5. Also loop calculations in supersymmetric theories need a consistent definition of γ5. In this paper we develop a new formalism, which allows us to define consistent regularization schemes. We use Grothendieck’s K-functor to construct finite-dimensional ...

CO2 emissions are the primary reason for global warming; hence, biological and chemical technologies converting into useful compounds being actively studied. Biological methods using enzymes can convert under mild conditions. Formate dehydrogenase (FDH) is a representative conversion enzyme. Its function was revealed after isolation from bacteria, yeast, plants. In this study, we evaluated pote...

Fourier-domain holography (FDH) has several advantages over image-domain holography for optical coherence imaging of tissue. Writing the hologram in the Fourier plane significantly reduces background arising from reference light scattered from the photorefractive holographic film. The ability to use FDH is enhanced by the use of a diffuse target, such as scattering tissue, rather than specular ...

A mutant of Methylobacterium extorquens AM1 with lesions in genes for three formate dehydrogenase (FDH) enzymes was previously described by us (L. Chistoserdova, M. Laukel, J.-C. Portais, J. A. Vorholt, and M. E. Lidstrom, J. Bacteriol. 186:22-28, 2004). This mutant had lost its ability to grow on formate but still maintained the ability to grow on methanol. In this work, we further investigate...

AIMS To assess protective efficacy of genetically modified Escherichia coli Nissle 1917 (EcN) on metabolic effects induced by chronic consumption of dietary fructose. MATERIALS AND METHODS EcN was genetically modified with fructose dehydrogenase (fdh) gene for conversion of fructose to 5-keto-D-fructose and mannitol-2-dehydrogenase (mtlK) gene for conversion to mannitol, a prebiotic. Charles ...

One-compartment biofuel cells without separators have been constructed, in which d-fructose dehydrogenase (FDH) from Gluconobacter sp. and laccase from Trametes sp. (TsLAC) work as catalysts of direct electron transfer (DET)-type bioelectrocatalysis in the two-electron oxidation of d-fructose and four-electron reduction of dioxygen as fuels, respectively. FDH adsorbs strongly and stably on Ketj...

We present the two-loop QCD helicity amplitudes for quark-gluon scattering, and for quark-antiquark annihilation into two gluons. These amplitudes are relevant for next-to-next-to-leading order corrections to (polarized) jet production at hadron colliders. We give the results in the ‘t Hooft-Veltman and four-dimensional helicity (FDH) variants of dimensional regularization. The transition rules...
