Fatty acid compositions in growing and resting cells of several strains of Pseudomonas putida (P8, NCTC 10936, and KT 2440) were studied, with a focus on alterations of the saturation degree, cis-trans isomerization, and cyclopropane formation. The fatty acid compositions of the strains were very similar under comparable growth conditions, but surprisingly, and contrary to earlier reports, tran...

We discuss the discretization using discontinuous Galerkin (DG) formulation of an elliptic Poisson problem. Two commonly used DG schemes are investigated: the original average flux proposed by Bassi and Rebay (J. Comput. Phys. 1997; 131:267) and the local discontinuous Galerkin (LDG) (SIAM J. Numer. Anal. 1998; 35:2440–2463) scheme. In this paper we expand on previous expositions (Discontinuous...

OBJECTIVES To identify differences in the prevalence of smoking and second-hand smoke exposure between Spanish and immigrant pregnant women, as well as the factors associated with continued smoking during pregnancy. METHODS An epidemiologic cross-sectional study was carried out in women attended at delivery in Zaragoza (Spain). A smoking questionnaire was used to collect the following variabl...

Many diseases and genetic disorders are associated with ABO and Rh systems of blood antigens. This study was conducted to determine the frequency of ABO and Rhesus (Rh) blood groups in District Rahim Yar Khan, Pakistan so that the results could be used for further application. A total of 9891 subjects including patients and healthy individual were sampled only belonging to District Rahim Yar Kh...

Type I signal peptidase (SPase I) catalyzes the hydrolytic cleavage of the N-terminal signal peptide from translocated preproteins. SPase I belongs to a novel class of Ser proteases that utilize a Ser/Lys dyad catalytic mechanism instead of the classical Ser/His/Asp triad found in most Ser proteases. Recent X-ray crystallographic studies indicate that the backbone amide nitrogen of the catalyti...

The addition of gangliosides to tissue culture cells causes a decrease in the tyrosine protein kinase activity of the epidermal growth factor (EGF) receptor and an inhibition of EGF-stimulated growth. Based on these data, the hypothesis that the EGF receptor is physiologically regulated by gangliosides has been proposed by E.G. Bremer, J. Schlessinger, and S. Hakomori (J. Biol. Chem. (1986) 261...

M. Bickel European Commission, Joint Research Centre, Institute for Reference Materials and Measurements, Retieseweg 111, 2440 Geel, Belgium Abstract The International Atomic Energy Agency (IAEA), through its Technical Co-operation Programme, has supported the establishment of many nuclear analytical and complementary laboratories in Member States. This included the development of capabilities ...

For a sample of 2440 non-supergiant Hipparcos stars belonging to Strr omgren's `early group' luminosities, temperatures, ages and distances have been determined. 241 stars younger than 30 Myr with well determined ages and space velocities fall within the local attened system, inclined 20 o to the galactic plane, called Gould's Belt. The system is dominated by a number of nearby prominent associ...

A new procedure is presented for the determination of low concentrations of lead and cadmium in water samples. Ligand assisted pseudo-stir bar hollow fiber solid/liquid phase microextraction using sol-gel sorbent reinforced with carbon nanotubes was combined with differential pulse anodic stripping voltammetry for simultaneous determination of cadmium and lead in tap water, and Darongar river w...
